| (57) A health bed device for actively supporting neck and shoulder and a method thereof
mainly comprises a head air bladder set and a neck and shoulder air bladder set installed
in the top surface, near a front end, of a cushion in a mattress. The head air bladder
set is not aerated, and the neck and shoulder air bladder set is full of air. Each
air bladder of the head air bladder set and the neck and shoulder bladder set is connected
to an aerating/deflating device through air tubes. The air tubes are connected to
a control device, so the control device derives the aerating/deflating device to aerate
or deflate the air bladders of the head air bladder set and the neck and shoulder
air bladder set. Each air tube is connected to a pressure sensor. When a pressure
sensor detects the pressure of a air bladder increasing suddenly, it can determine
that a user changes his/her sleep position from lying on his/her back to lying on
his/her side. The air bladders whose pressures increased are the air bladder pressed
by the user. Meanwhile, the control device derives the aerating/deflating device to
automatically decrease the pressures inside the air bladders to setting values, and
to aerate the air bladders of the head air bladder set to setting value so as to reduce
the pressure on the user's shoulder.

BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] This invention relates generally to a health bed device for actively supporting neck and shoulder and a method thereof, and more specifically, to a device and a method that detects a pressure value of each air bladder with pressure sensors to determine whether a user change his/her sleep position from lying on his/her back to lying on his/her side and automatically reduces the pressure on the user's shoulder.
2. Description of the Prior Art
[0002] There are a variety of prior health beds, such as memory beds, energy beds, etc. A common point of such health beds is that these beds passively support a user. That is, springs inside the beds are the device to support a user's body. In fact, the springs are compressed by the user's body weight and cannot actually support the user's body. Therefore, these health beds cannot solve a user's sleep problems.
[0003] In order to solve the problem of passive support of the prior health beds, the inventor of this invention has applied a series of patent applications regarding health beds that can actively support a user's spine: PCT Appl. No. PCT/CN2007/0002585 (Ref. 1), PCT Appl. No. PCT/CN2007/002602 (Ref. 2), PCT Appl. No. PCT/CN2007/002956 (Ref. 3), and U.S Pat. Appl. No.12/493,196 (Ref. 4). However, the patent applications mentioned above focus on supporting a user's spine but overlook problems of hand numbness, neck and shoulder pain, and stiff neck resulting from the fact that a user's shoulder is not able to bear the user's body weight when the user lie on his/her side for a long time.
SUMMARY OF THE INVENTION
[0005] One object of this invention is to provide a health bed device for actively supporting a user's neck and shoulder and a method thereof. By detecting whether pressure values of the air bladders of a neck and shoulder air bladder set rise suddenly, it can determine whether a user change his/her sleep position from lying on his/her back to lying on his/her side. If a user's sleep position is determined to be lying on his/her side, the pressure values of the air bladders whose pressure was rising will be decreased to settings, so the pressure on the user's shoulder can be reduced.
[0006] The other object of this invention is to provide a health bed device for actively supporting a user's neck and shoulder and a method thereof. A head air bladder set, which is not inflated, is installed in the heath bed. When a user is lying on his/her side, the head air bladder set will be inflated to settings, so the position of the user's head will be up and the position of the user's shoulder will be down, and the pressure on the user's shoulder can be reduced.
[0007] A health bed device for actively supporting a user's neck and shoulder and a method thereof, which can achieve the objects, mainly comprise a mattress, a head air bladder set, a neck and shoulder air bladder set, a pressure sensor set, a air tube set, an aerating/deflating device, and a control device. The head air bladder set and the neck and shoulder air bladder set are installed in the top surface, near a front end, of the mattress, so when a user lies down, the user's head lies on the head air bladder set, and the user's neck and shoulder lie on the neck and shoulder air bladder set.
[0008] Each air bladder of the head air bladder set and the neck and shoulder air bladder set is connected to one end of an air tube of the air tube set, and the aerating/deflating device is connected to the other end of the air tube. Every air tube is connected to a pressure sensor. The control device derives the aerating/deflating device through the air tube set to aerate or deflate the air bladders of the head air bladder set and the neck and shoulder air bladder.
[0009] Under normal condition, the air bladders of the head air bladder set are not aerated, and the air bladders of the neck and shoulder air bladder set are full of air. When the control device receives the signal detected by the pressure sensors that the pressures of all the air bladders of the neck and shoulder air bladder set increase, it could determine that the user changes his/her sleep position from lying on his/her back to lying on his/her side. When the control device receives the signal that the pressure value of the air bladder which is pressed by the user's shoulder is the highest, the control device will turn on the control switches. Then, the aerating/deflating device aerates the air bladders of the head air bladder set to the setting pressure and deflates the air bladders of the neck and shoulder air bladder set to the setting pressure. As a result, the user's shoulder is lowered, and the user's head is raised, so the pressure on the user's shoulder is reduced.

a head air bladder set 21 comprising a top layer 211 and a plurality of air bladders S1 and S2, which are averagely distributed on the surface of the top layer 211, each air bladder S1 and S2 having a plurality of aerating/deflating holes (not shown in figures); the head air bladder set 21 is installed in the space of the higher layer of the upper accommodation room 121, and the air bladder S1 and S2 are in a state of not being aerated;
a neck and shoulder air bladder set 22 comprising a top layer 221 and a plurality of air bladders S3∼S5, which are averagely distributed on the surface of the top layer 221, each air bladder S3∼S5 having a plurality of aerating/deflating holes (not shown in figures); the neck and shoulder air bladder set 22 is installed in the space of the lower layer of the upper accommodation room 121, and each air bladder S3-S5 is aerated and full of gas, in which the height of the air bladders is nearly equal to the height of the upper accommodation room 121, so the surface of the mattress 1 is not affected by the aerated neck and shoulder air bladder set 22 and does not raise;
an air tube set 3 comprising a plurality of air tubes 31, one end of each air tube 31 connected to one of the aerating/deflating holes of each air bladder S1∼S5 of the head air bladder set 21 and the neck and shoulder air bladder set 22, and the other end of each air tube 31 penetrating the penetrating holes 123 of the cushion 12 and the lower accommodation room 122 so as to expose the end from the open 11 on the bottom of the mattress 1 and connected to the first tube 41 of a three-way tube 4;
an aerating/deflating device 5 having a plurality of venting holes (not shown in figures), each venting hole is electrically connected to a control switch 6, as shown in Fig. 4, each control switch 6 connected to the second tube 42 of the three-way tube 4, so that the aerating/deflating device 5 is able to aerate and deflate the air bladders S1∼S5 of the head air bladder set 21 and the neck and shoulder air bladder set 22;
a pressure sensor set 8 comprising several pressure sensors 81, the pressure sensors 81 connected to the third tube 43 of the three-way tube 4 so as to detect the pressure inside each air bladder S1∼S5 of the head air bladder set 21 and the neck and shoulder air bladder set 22; and
a control device 7 connected to the aerating/deflating device 5 and each of the control switches 6 and electrically connected to each pressure sensor 81 of the pressure sensor set 8, and the control device 7 is able to turn on or turn off the control switch 6 according to the signal of the detected result from the pressure sensor 81, so the aerating/deflating device 5 is able to aerate or deflate each air bladder S1∼S5 of the head air bladder set 21 and the neck and shoulder air bladder set 22.
[0012] In addition, the control device 7 can be a PC (personal computer), a laptop, a PDA, or other electronic products with screens or input interfaces, and the input interface can be buttons, keys, a touch screen, or a remote controller.
[0013] Moreover, the top surface of the cushion 12 of the mattress 1 can be covered by an upper pad 13 to position the head air bladder set 21 and the neck and shoulder air bladder set 22 so as to make a user more comfortable. The upper pad 13 can be made of memory foam, latex pad, different types of foam materials, or flexible materials.
[0014] Furthermore, the aerating/deflating device 5 can also be installed in the mattress 1, so every air tube 31 of the air tube set 3 does not expose from the mattress 1.
[0015] Please refer to Fig. 2, Fig. 3A, 3B, and Fig. 4A, 4B, 4C illustrating schematic operation views of the present invention. When a user 9 is lying on his back on the surface of the mattress 1, the user's head is lying on the air bladders S1∼S2 of the head air bladder set 21, and the user's shoulder is lying on the air bladders S3∼S5 of the neck and shoulder air bladder set 22. Meanwhile, the air bladders S1∼S2 are not aerated, and the air bladders S3∼S5 are full of gas. Because the user's whole back shares the pressure of the user's body weight, the pressures of each air bladder S3∼S5 of the neck and shoulder air bladder set 22 detected by the pressure sensors 81 are almost the same. As shown in Fig. 4A, the pressures of the air bladders S1∼S2 of the head air bladder set 21 are close to 0, and the pressures of the air bladders S3∼S5 of the neck and shoulder air bladder set 22 are 1 kg/cm2. When the user 9 changes his sleep position from lying on his back to lying on his side, the user's shoulder bears the pressure of his body weight. Therefore, the pressures of each air bladder S3∼S5 of the neck and shoulder air bladder set 22 detected by the pressure sensors 81 increase. Among these air bladders S3∼S5, the pressure of air bladder S4, on which user's shoulder is lying, increases most. It can not only determine the user 9 changed his sleep position from lying on his back to lying on his side, but also find out which air bladder is pressed by the user's shoulder through the pressure sensors 81. As shown in Fig. 3A and Fig. 4B, the pressures of the air bladders S3 and S5 of the neck and shoulder air bladder set 22 increase to 1.5kg/cm2, and the pressure of the air bladder S4 increases to 2kg/cm2. Hence, it can determine that air bladder S4 is pressed by the user's shoulder. When the control device 7 receives the pressure signal detected by the pressure sensors 81, the control device 7 will turn on the control switch 6, so the aerating/deflating device 5 is able to deflate the air bladders S3∼S5 of the neck and shoulder air bladder set 22. After the pressures of the air bladders S3∼S5 decrease to the settings, the control switch 6 is turned off. Meanwhile, the control device 7 will turn on the control switch 6, so the aerating/deflating device 5 is able to aerate the air bladders S1∼S2 of the head air bladder set 21. After the pressures of the air bladders S1∼S2 increase to the settings, the control switch 6 is turned off. As shown in Fig. 3B and Fig. 4C, the pressures of the air bladders S3 and S5 of the neck and shoulder air bladder set 22 decrease to 1 kg/cm2, the pressure of the air bladder S4 decreases to 1.5kg/cm2, and the pressures of the air bladders S1 and S2 of the head air bladder set 21 increase to 0.5kg/cm2. As a result, the user's shoulder is lowered, and the user's head is raised, so the pressure on the user's shoulder is reduced.
[0016] The pressure values mentioned in Fig. 4A to 4C provided above is a preferred embodiment of the present invention to show the technical features of the invention, but not to limit the claims of the invention.
[0017] In addition, if the user 9 feels there is not enough pressure in the head air bladder set 21 or there is too much pressure in the neck and shoulder air bladder set 22, the amount of air aerated or inflated in every air bladder S1∼S5 can be individually adjusted through the input interface of the control device 7.
[0018] When the control device 7 receives the signal detected by the pressure sensors 81 that the pressures of air bladders S3-S5 of the neck and shoulder air bladder set 22 return to the initial values, it can be determine that the user changes his sleep position from lying on his side to lying on his back. The control device 7 will turn on the control switch 6, and the aerating/deflating device 5 will deflate the air bladders S1 and S2 of the head air bladder set 21 to completely remove the pressures of the air bladders S1 and S2, and will aerate the air bladders S3-S5 of the neck and shoulder air bladder set 22 to the initial pressure values.
[0019] Comparing with prior arts, the present invention has the following advantages, which include:
- 1. The invention determines if a user changes his/her sleep position from lying on his/her back to lying on his/her side by detecting whether the pressures of the air bladders of the neck and shoulder air bladder set increase suddenly. If it determines the user is lying on his/her side, the pressures of the air bladders whose pressures increased will be automatically decreased to the settings to reduce the pressure on the user's shoulder.
- 2. A head air bladder set, which is not inflated, is installed in the heath bed of the present invention. When a user is lying on his/her side, the head air bladder set will be inflated to settings, so the position of the user's head will be up and the position of the user's shoulder will be down, and the pressure on the user's shoulder can be reduced.
[0020] Although the invention has been disclosed and illustrated with reference to particular embodiments, the principles involved are susceptible for use in numerous other embodiments that will be apparent to persons skilled in the art. This invention is, therefore, to be limited only as indicated by the scope of the appended claims.
