Description

[0001] The invention relates to a gas switcher with manometer and a collector with gas switcher with manometer, that is designed especially to be used in land ambulances, sea ambulances and air (aircraft, helicopter) ambulances, takes up less space by saving material compared to known systems, prevents forced pressure leaks by making the manometer positioned directly on the switcher more protected, and is practical to install and use, in which the manometer switcher can be used independently (alone) or as collector with gas switcher with manometer by mounting the manometer directly on the switcher so that the knob controlling the switcher and the manometer are on the same axis.

[0002] Today, running out of oxygen supplied by cylinders that is used in emergency response vehicles such as land ambulances, air (aircraft, helicopter) ambulances, sea ambulances, etc., in small health centres, mobile health centres and at home where patients are being cared for, where medical oxygen is used, puts human life at risk, and continuity of oxygen flow is essential for patients. Insufficient oxygen can cost the patient's life during critical interventions. In the cases in which oxygen runs out, difficulties are experienced when changing the oxygen cylinder. Especially the time lost during the replacement of the oxygen cylinder or cylinders often endangers the patient's life. In order to solve these problems, first the product that is the subject of the utility model no. TR2017/01986 with the invention title "Multifunctional Oxygen Switcher" was designed. Then, the product that is the subject of the utility model no. TR2018/13963 with the invention title "Automatic Oxygen Switcher", which provides gas flow automatically by switching to the other oxygen cylinder when the gas in one oxygen cylinder runs out, was designed. Above mentioned gas flow switchers can be used stand-alone (independent) or by being mounted on multiplexers (distributors) such as collectors with gas sockets on them. After all, the product that is the subject of the utility model no. TR2017/02974 with the invention title "Part for connecting the oxygen gas equipment" has been designed for the assembly of parts such as switchers, collectors, etc.

[0003] The pressure gauge (manometer) is usually located on the collector (distributor), which takes up an extra space and causes the collector to be long (and therefore more material to be used). The pressure gauge is more unprotected and vulnerable to impacts when it is positioned on the collector, mostly when the vehicle is on move. This may cause early wear and gas leaks. If the pressure gauge (manometer) is not at an easily visible angle on the collector, it causes difficulties for medical teams during gas pressure control in moving vehicles.

[0004] The system that is the subject of the invention was designed by taking these problems into consideration. The aim here is to position the manometer on the oxygen switcher, to keep the manometer indicator constant regardless of the button when the button is turned, and to clearly measure the instantaneous pressure of the gas passing through the switcher. In this way, the user (healthcare worker, caregiver) will be able to instantly monitor the gas used.

[0005] The subject of the mentioned invention, "gas switcher with manometer" can be used alone (independent / stand-alone) or can be used acuplated by side of the collector or mounted directly on the collector. It can be positioned anywhere desired, away from the collector in cases where direct connection to the collector is not desired; in this case, the gas flow is provided by tubes (hoses). When used as a whole with the collector (manometer and switcher as a single piece), material savings are achieved as there is no need for the part where the pressure gauge (manometer) is mounted by eliminating the section reserved for the pressure gauge (manometer). Or it provides the opportunity to position more oxygen sockets in the same size collector.

[0006] The gas switcher with manometer, which is the subject of the invention, is a more robust product in terms of structure, since the manometer and the changer knob provide integrity. The knob acts as an external shield in case of any impact, minimizing the impact on the manometer body (indicator) positioned inside. In this way, the service life of the manometer body (indicator) is extended and preventing O-ring wear that may occur due to possible impacts, the possibility of oxygen leakage from the pressure indicator (manometer) is minimised. Mounting the manometer on the knob of the switcher has made the product more useful in terms of design. While turning the knob connected to the switcher mechanism, the manometer (pressure indicator) itself always remains fixed, that is, it is independent of the turn of the knob. It will provide healthcare teams with a more comfortable working opportunity as it provides convenience while monitoring the pressure gauge.

[0010] The subject of the invention is gas switcher with manometer, characterised by comprising switcher body (1) that has centring pin bearing (1a), opening-closing ball o-ring slot(s) (1b), gas inlet path(s) (1c), gas outlet path(s) (1d), positioning pin slot (1e), screw bearing (1f), fixing part bearing (fixing ball cavity) (1g), gas inlet channel (hole) (1h), gas outlet channel (hole) (1i,); gas passage cavity (1j) between the switcher body (1) and fixed disk (5); opening-closing ball o-ring(s) (2), centring pin (3), positioning pin (4); fixed disk (5) that has fixed disk chamfer (5a), opening-closing ball bearing(s) (5b), centring pin hole (5c), positioning pin hole (5d), hole(s) for the gas entry into the system (5e) and working cavity that prevents the friction of the cam shaft (5f); opening-closing ball(s) (6); shaft with cam (7) that has cam slot (7a), positioning pin channel (bearing) (7b), ball roll bearing(s) / peak plane (7c), friction plane (bearing) of the friction seal (7d), internal sealing o-ring bearing (7e), snap ball slot(s) / torque adjustment slot(s) (7f), hole of the rotating part (7g) and adjustment bushing bearing (plane) (7h); friction gasket (8); internal sealing o-ring (9); external sealing o-ring (10); cam shaft bearing and manometer carrier (11) comprising cam shaft bearing (11a) that has cam shaft seating slot (1IaI), friction surface of the friction gasket (11a2), notch(es) (11a3), capillary duct (11a4), hole / channel that allows the gas to reach the manometer (11a5), external sealing o-ring bearing (slot) (11a6), snap ball hole(s) (11a7), snap ball(s) (11a8), snap ball spring(s) (11a9), spring support ring bearing (cavity) (11a10), screw clamping ring bearing (cavity) (11a11), fixing part cavity (fixing ball cavity) (11a12) and capillary duct pool (11a13), and manometer carrier (gas conveyor to the manometer) (11b) that has carrier column(s) (11b1), space for rotating part (cavity) (11b2), angled cavity(s) (11b3), threaded hole for manometer mounting (11b4), sealing o-ring bearing (slot) for manometer mounting (11b5), adjustment cavity (manometer positioning cavity) (11b6), gas pool (11b7), and sealing o-ring of the manometer (11b8); fixing part (ball) (12); spring support ring (13); screwed clamping ring (14) that has threaded zone (14a), wrench zone (14b), spring support ring cavity (14c) and cam shaft bearing and manometer carrier mounting clamping plane (14d); rotating group (15) that has rotating part (screw) (15a), washer (roundel) (15b) and adjustment bushing (15c); knob (16) that has rotating part hole (16a), rotating part mounting slot (16b), washer bearing (16c), support hole (cavity) (16d), manometer slot (16e) and switcher position identifier (16f); lock nut (manometer position fixing nut) (17); and manometer (18). If the system of the invention is integrated with the collector, it has collector main body with switcher (1) instead of the switcher body (1). In other words, when the system that is the subject of the invention is independent, it has the collector main body with switcher (1), whereas if the collector and the switcher with manometer body are made as a single piece, it has the collector main body with switcher with manometer (1).

[0011] The gas switcher with manometer that is the subject of the invention can be a single model (model with a single oxygen inlet) or it can be a multiple model (model with multiple oxygen inlets) depending on the place and purpose where the system will be used. These models may have a single oxygen outlet or multiple oxygen outlets, that is, there may be inlet and outlet holes in different combinations.

[0012] In the gas switcher with manometer that is the subject of the invention, the switcher body (1) allows the gases coming from the cylinders to enter the system through the gas inlet path(s) (1c). There are gas inlet path(s) (1c) on different surfaces of the switcher body (1); depending on where the system will be positioned, the gas inlet path(s) (1c) that are not intended to be used are closed with blind plugs. Figure 1 shows the side and bottom gas inlet path(s) (1c). For example, the gas inlet path(s) (1c) on the bottom surface are closed with a blind stopper and the hoses (pipes) coming from the cylinders are attached there using the gas inlet path(s) (1c) on the front surface. With the same logic, the gas exit path(s) (1d) are also located on different surfaces; depending on where the system will be positioned, the unwanted gas outlet path(s) (1d) are closed with a blind plug and the gas is directed to the gas outlet path(s) on the other surface (1d). There is/are an opening-closing ball o-ring slot(s) (1b) at the inlets that allow the gas coming from the gas inlet path(s) (1c) to enter the system. Sealing is ensured by placing opening-closing ball o-ring slot(s) (2) in these slots (1b). The centring pin (3) ensures that the switcher body (1) and the fixed disk (5) are in the desired alignment (axis). The function of the positioning pin (4) is to ensure that the fixed disk (5) centred inside the switcher body (1) is stopped (fixed) in the desired position and to restrict the movement of the cam shaft (7) to the desired extent. There is a working cavity (5f) in the fixed disk (5) that prevents the friction of the cam shaft (7). Gases coming into the system from the oxygen tube(s) and entering through the gas inlet path(s) (1c) pass through the gas inlet channel (hole) (1h) and reach the opening-closing ball(s) (6) positioned on the fixed disk (5). When the system is closed, the opening-closing ball(s) (6) rest on the ball roll bearing(s) / peak plane (7c) on the cam shaft (7) [at the edges of the cam slot (7a); in other words, the ball/balls (6) close the gas inlet channel(s) (1h) in the switcher body (1) by pressing on the opening-closing ball(s) o-ring(s) (2). Ball rolling bearings / peak plane(s) (7c) and cam slot (7a) are designed in accordance with the diameter of the ball (6), so that the balls (6) roll more easily. The system is turned on by moving the cam shaft (7) to the right or left. For example, if the system has two balls; when the cam shaft (7) is turned to the right, the opening-closing ball (6) on the right rises to the cam slot (7a) under the effect of the pressure from the tube connected to that side, allowing gas to pass. Meanwhile, the other opening-closing ball (6) continues to be located on the ball roll bearing(s) / peak plane (7c). In other words, the opening-closing balls (6) with their positions according to the movement of the cam slot (7a) either allow or do not allow gas passage.

[0013] The gas coming to the opening-closing ball bearing(s) (5b) positioned on the fixed disk (5) enters the system from whichever of the opening-closing ball (6) is open, that is, whichever is in the cam slot (7a); the gas passes through the hole(s) for the gas entry into the system (5e) on the fixed disk (5) and reaches the gas passage cavity (1j) around the fixed disk (5), that is, the space between the fixed disk (5) and the switcher body (1). Gas circulates easily around the fixed disk (5) by means of the gas passage cavity (1j) left between the periphery of the fixed disk (5) and the switcher body (1). The fixed disk chamfer (5a), designed to be positioned on the gas outlet path (1d) located at the back of the switcher body (1) allows, by means of the space it provides, the gas to pass through the gas outlet channel (hole) (1i) and exit easily through the gas outlet path (1d).

[0014] Our system, which is the subject of the invention, ensures instantaneous monitoring of the pressure of this gas in motion by providing communication between the gas entering and exiting the system and the manometer.

[0015] The centring pin bearing (1a) on the switcher body (1) and the centring pin hole (5c) on the fixed disk (5) align and these two parts are centred with the centring pin (3); a gas passage cavity (1j) is created, which is the ideal space between the fixed disk (5) surroundings and the switcher body (1) for gas passage. The positioning pin hole (5d) on the fixed disk (5) and the positioning pin slot (1e) on the switcher body (1) are aligned and the fixed disk (5) is fixed to the switcher body (1) with the positioning pin (4). The positioning pin (4), by means of its part remaining as a protrusion on the fixed disk (5), sits (positioned) in the positioning pin channel (bearing) (7b) in the cam shaft (7) and restricts the movement of the cam shaft (7) to the specified extent. In this way, the opening-closing ball(s) (6) moves in a limited manner in the ball bearing(s) (7c).

[0016] The friction gasket (8), which is used to facilitate movement by minimising the friction between the cam shaft (7) and the cam shaft bearing and the manometer carrier (11), is assembled / seated on the friction plane (bearing) of the friction seal (7d). The function of the friction gasket (8) is to create an oil-free mechanism by means of its sliding feature. Normally, an expensive oil that is not harmful to health could be used in this part. However, this friction gasket (8) prevents negative formations that affect the operation of the system due to oil sedimentation over time, prevents the possibility of oil particles mixing into oxygen gas, and also reduces the product cost. The friction gasket (8) is made of material with a low friction coefficient and very affordable cost and is harmless to health.

[0017] In order to prevent gas leakage between the cam shaft (7) and the cam shaft bearing and manometer carrier (11), an internal sealing o-ring (9) is attached to the internal sealing o-ring bearing (7e) on the cam shaft (7).

[0018] The friction gasket (8) can cover the hole that allows the gas to reach the manometer (11a5), making gas passage difficult or obstructing it. This is an undesirable situation. By means of the capillary duct (11a4) opened on the inner wall of the cam shaft bearing (11a) [at the level of the entrance of the hole that allows the gas to reach the manometer (1 1a5)], this problem is eliminated by providing gas flow between the cam shaft (7) next to the friction gasket (8) and the cam shaft bearing and manometer carrier (11). The gas passing through the capillary duct (1 1a4) comes to the capillary duct pool (1 1a13) and from there it moves upwards by means of the hole / channel that allows the gas, positioned in the carrier column (11b1), to reach the manometer (11a5). By means of this channel (11a5) opened in the carrier column (11b1), the gas reaches the gas pool (1 1b7) and goes to the manometer (18).

[0019] Snap ball slot(s) / torque adjustment slot(s) (7f) ensures that the positioning given to the snap ball(s) (11a8) remains constant while turning the knob (16) and stops at the desired torque force, that is, the constant torque determined by the standards (standard: minimum 6 Newtons). In this way, the knob (16) is prevented from rotating spontaneously due to the movements of the ambulance, etc. The snap ball slot(s) / torque adjustment slot(s) (7f) are removed from the environments where gas passes, that is, they do not have any contact with the gas.

[0020] After the assembly of the cam shaft (7) to the cam shaft bearing and manometer carrier (11), an external sealing o-ring (10) is attached to the outer sealing o-ring bearing (11a6) to prevent gas leakage between the switcher body (1).

[0021] The cam shaft (7) is attached to the cam shaft bearing (11a) so that the cam slot (7a) in the pre-assembled cam shaft (7) is aligned with the fixing piece gap (11a12) in the cam shaft bearing and manometer carrier (11).

[0022] The upper part of the cam shaft (7) on which the friction gasket (8) and internal sealing o-ring (9) are assembled is placed inside the cam shaft bearing and the manometer carrier (11) so that the cam slot (7a) and the hole that allows the gas to reach the manometer (11a5) are in the same alignment. It is fixed by placing first the snap ball(s) (11a8) and then the snap ball spring(s) (11a9) into the snap ball(s) hole(s) (11a7) on the cam shaft bearing and manometer carrier (11) and then, by attaching the spring support ring (13) to the spring support ring bearing (11a10) in order to prevent the spring/springs from coming out.

[0023] The screwed clamping ring (14) is placed in such a way that the screwed clamping ring on the cam shaft bearing (11a) comes to the screw clamping ring bearing (11a11).

[0024] Before placing the manometer (18) in the threaded hole for manometer mounting (bed) (11b4), the sealing o-ring of the manometer (11b8) is placed in the sealing o-ring bearing (slot) for manometer mounting (11b5) in order to prevent forced gas leaks. A lock nut (17) is attached to the manometer (18), then the manometer (18) is attached to the manometer carrier (1 1b) and tightened all the way. It is left that way if the writings on the manometer (18) are at the desired angle; if the manometer clockface view is not in the desired position, the manometer (18) is turned in the reverse direction until the desired position is reached and the lock nut (17) is tightened so that it appears in the desired position. What allows the manometer (18) to be turned in this reverse direction and the sealing to be maintained is the adjustment cavity (1 1b6). The manometer (18) and other parts assembled on the cam shaft bearing and manometer carrier (11) are passed through the knob (16) as a whole, and the manometer (18) fits into the manometer slot (16e).

[0025] The opening-closing ball o-ring(s) (2) are placed in the opening-closing ball o-ring slot(s) (1b) on the switcher body (1). The fixed disk (5) is installed by placing the positioning pin (4) into the positioning pin slot (1e) on the switcher body (1), and the centring pin (3) into the centring pin bearing (1a). Opening-closing ball(s) (6) are placed on the opening-closing ball bearing(s) (5b). By aligning fixing piece bearing (1g) located in the switcher body (1) and the fixing piece cavity (fixing ball cavity) (11a12) in the cam shaft bearing and manometer carrier (11) on the same axis, fixing part (ball) (12) (being placed in the fixing part cavity (11a12) in the cam shaft bearing and manometer carrier (11)) and the pre-assembled groups, that is, the manometer (18), the knob (16), the cam shaft bearing and the manometer carrier (11), the cam shaft (7), and the screwed clamping ring (14), are all pushed together into the switcher body (1). The knob (16) is pulled up to the bottom surface of the manometer (18), and the specially designed wrench is inserted into the screwed clamping ring (17) by taking advantage of the cavity created. While the threaded zone (14a) of the screwed clamping ring (14) is placed on the screw bearing (1f) in the switcher body (1), the wrench zone (14b) is tightened with a specially designed wrench.

[0026] During the installation of the rotating group (15) into the system, it is first assembled within itself. First, the washer (15b) is attached to the rotating part (15a), then the adjustment bushing (15c). The knob (16) is lifted up to the distance between it and the manometer (18). Then, the rotating part (15a) passes through the space for rotating part (cavity) (11b2) and is attached to the hole of the rotating part (7g) in the cam shaft (7). While the washer (15b) attached to the rotating part (15a) is positioned to the front on the rotating part (15a), and the adjustment bushing (15c) is positioned to the forward side, the pulled-up knob (16) is placed on the rotating part (15a) through the cavity between the slot (16b) on the knob (16), the washer (15b) and the adjustment bushing (15c), and the rotating part (15a) is tightened to the end. They are the angled cavities (11b3) on the carrier column(s) (11b1) that allow the system to be minimised by providing maximum material saving and the movement of the rotating part (15a) to be at the specified angle. If material saving is not desired, the movement of the rotating part (15a) can be achieved at the desired angle without creating angled cavities (11b3).

[0027] The adjustment bushing (coupling bushing) (15c), which is placed by pushing up to the coupling bushing bearing (7h) on the cam shaft (7), ensures that the knob (16) is at an equal distance from the manometer indicator (18), that is, it remains in the centre. The washer (15b) integrates with the knob (16) and closes the rotating part mounting slot (16b) opened for assembly and prevents the rotating part (15a) from being released, and also serves to distribute the pressure.

[0028] The rotating part (15a) is easily placed in the rotating part hole (16a) by means of the rotating part mounting slot (16b). During this assembly, the adjustment bushing (15c) remains on the inside of the knob (16) and the washer (15b) remains on the outside. When the rotating part (15a) starts to be tightened, the knob (16) stuck between the washer (15b) and the adjustment bushing (15c) is fixed. When the rotating part (15a) tightening process is completed, the end part of the rotating part (15a) is placed on the support hole (16d). In this way; although the rotating part (15a) can be installed (shorter) without being placed on the support hole (16d), the system can be operated, by making the rotation moment healthier, damage such as breakage, warping, etc. in the rotating part mounting slot (16b) and the rotating part hole (16a) is prevented under any stress.

[0029] Rotating group (15) comprises the rotating part (screw) (15a), which provides the connection between the knob (16) and the cam shaft (7), washer (roundel) (15b) that ensures the closure/integration of the slot opened in the knob (16), that is, the rotating part mounting slot (16b) and the adjustment bushing (15c), which enables the adjustment (centring) of the middle axis distance between the knob (16) and the cam shaft (7). The head part of the rotating part (screw) (15a) also serves as a direction indicator and shows the closed/open position of the knob (16). The fixing part (12) prevents the cam shaft bearing and the manometer carrier (11) from rotating on the switcher body (1).

[0030] The cam shaft bearing and manometer carrier (11) in the system of the invention also have

• cam shaft seating slot (cavity) (11a1) that has a cavity to accommodate the lower part of the cam shaft (7) and allows the gas to pass through the gas outlet channel (hole) (1i) and reach the gas outlet path(s) (1d) by means of the gas passage cavity (1j) formed between the lower part of the cam shaft (7) and its own walls,
• the friction surface of the friction gasket (11a2) with which the friction gasket comes into contact,
• notch(es) (11a3) that prevent the contact of the opening and closing ball(s) (6) with the cam shaft bearing (11a),
• the fixing part cavity (11a12) that prevents the cam shaft bearing and manometer carrier (11) from rotating on the switcher body (1),
• snap ball(s) (11a8) and snap ball spring(s) (11a9), which enable the rotated knob (16) to stop at the desired points and at the desired torque force and guide the user by giving an audible warning,
• the space for rotating part (cavity) (11b2), which is the area that allows the cam shaft (7) to rotate at the specified angle,
• adjustment cavity (manometer positioning gap) (11b6) which allows leaving the manometer (18) during assembly if the clockface view (texts) on the manometer (18) is at the desired angle / position, and turning it in the reverse direction until the desired position is achieved if it is not in the desired position, and

[0031] The system that is the subject of the invention cannot be limited to what is described here and to the model shown in the picture. Changes can be made to the shape of the invention without depending on the material and size, the places of the parts used can be changed, the number of parts used can be changed, different parts with similar features can be used instead of the used parts, and the system can be used without some parts if desired.

[0032] For example;

• If the system of the invention is integrated with the collector, it has the collector main body with gas switcher with manometer (1) instead of the gas switcher body with manometer (1) (Figure 13). Figure 12 shows the state of the art.
• Apart from the mounting system described above, parts of the system can be mounted in different ways.
• In order to prevent the sound that may occur due to the friction between the manometer (18) and the knob (16), an o-ring or friction ring can be installed in the slot to be opened in the manometer slot (16e) located inside the knob (16).
• In uses with a flush-mounted additional panel, the switcher position identifier (16f) can be placed on different parts of the knob (16) in different shapes. The switcher position identifier (16f) may have various shapes such as lines, slots, screws, projections, etc. This switcher position identifier (16f) allows to indicate the closedopen positions of the system. Figure 11 also shows models with the switcher position identifier (16).
• In order to facilitate the assembly or disassembly of the system (especially for ease of maintenance phases), the knob (16) may be in two parts (for example, the lower small part and the upper larger part).
• The cam shaft bearing and manometer carrier (11) can be a single piece as seen in the pictures, or they can be produced as two separate parts, the cam shaft bearing (11a) and the manometer carrier (11b).
• If suitable materials are used in the parts used in the system, the system of the invention can be used for all kinds of fluids such as different gases, liquids, etc. For example, if it is intended to be used for milk, food-grade materials should be used. If acidic liquids are desired to be used, acid-resistant materials should be used.
