[0001] Two inventions combined in the application relate to medical equipment, namely, to
neonatal equipment intended to exercise care and intensive therapy of new-born and
weakened infants in departments of emergency and medical pediatrics, maternity homes
and research institutes of maternity and childhood care.
[0002] Equipping of resuscitation wards with incubators-transformers allow to reduce by
two times the areas required for placement of incubators and resuscitation systems
and to sufficiently increase the quality of care of premature neonates having extremely
low mass of body.
[0003] There is the known neonatal resuscitation complex made with a possibility of transformation
into incubator for neonates and providing optimal conditions for resuscitation, care
and nursing of neonates Giraffe OmniBed of Ohmeda Medical Inc., USA, Internet-sites,
for example, www/bmt-medical.ru, that, as for essential characteristics in aggregate,
is the nearest analog of the first invention of the claimed group of inventions.
[0004] The device contains the infant module with lateral panels and a hood installed on
a transport trolley, stand for the hood relocation with illumination device and control
unit with a monitor, module of equipment connection, box for accessories storage.
In three lateral panels, installed in infant module with the help of hinges, there
are made oval windows providing access to the patient during resuscitation activities
and infant care procedures. Inside the hood there is placed an IR lamp with curtains.
The hood is fixed on the upper bar that is installed on a stand with lifting mechanism
for the hood relocation in vertical in relation to the neonate bed. The box for storage
of accessories for the neonate care is installed under the infant module.
[0005] The disadvantages of the known device are:
- labour intensiveness of product manufacture from numerous assembly units;
- displacement of the infant module hood during opening and closing as well as its stay
in open position above the bed is not a desirable psychological factor for the neonate,
the ergonomic parameters of product are not provided;
- it is difficult to make disinfection of the hood with the IR lamp with curtains placed
inside because it is located in upper position above the neonate bed.
[0006] The transformation of the known incubator device Giraffe OmniBed of Ohmeda Medical
Inc., USA into the resuscitation system is made by the method known from the patent
DK 1053736 that, as for essential characteristics in aggregate, is the nearest analog of the
second invention of the claimed group of inventions. Transformation is made by pressing
the button to start displacement in vertical plane in relation to the bed for neonate
of the hood with heating device when changing the function between the lower position,
in which it operates as an incubator for newborn, and the upper position, in which
it operates as a heating device. To provide for easiness of medical operations three
lateral panels can be folded manually, partially or completely. The process of transformation
from resuscitation system to incubator is made in reverse order: the lateral panels
will be installed, and further, when pressing the button, the hood starts moving from
upper position to lower position until interaction with lateral panels.
[0007] The disadvantages of the known method are:
- necessity of manual manipulations to provide for complete transformation from incubator
to resuscitation system and vice-versa, that is not desirable for observance of the
medical staff hands sterility and also increases the interval of time, for example,
from the beginning of the incubator transformation until the beginning of necessary
resuscitation measures for the patient;
- operations for the hood opening and closing are carried out above the neonate's bed,
that is dangerous for the patient in alarm situations, for example, with power supply
disconnections, damages etc.
[0008] The task, to the solution of which each from the proposed inventions is directed,
is an increase of performance features of incubator-resuscitation system for newborns.
[0009] When realizing the present inventions the achievable technical result consists in
excluding the necessity of using manual operations for provision with full access
to the patient and the hood stay above the patient bed during the product transformation,
and also increase of easiness of work of the medical staff for the neonate care.

labor expenses during the product manufacture and assembly and also allows to exclude,
as compared with the prototype, the manual operations and reduce the product transformation
time, moreover, to provide for disinfection of the infant module the hood is easily
dismounted, thus increasing the easiness and quality of performed works,
- division of the hood in longitudinal axis into two parts each of which is installed
in articulated manner in the infant module body allows to open/close the hood and
compactly place under the patient's bed,
- placement of the hood windows symmetrically on the hood lateral surfaces allows to
have a comfortable access to the patient during medical activities carried out by
the medical staff in the closed position of the hood,
- performance in lateral walls of the enlarged windows for access to the patient with
the doors installed in articulated manner allows to take the neonate from incubator
with the closed position of the hood,
- performance of the handrail from the opposite side from the stand on infant module
body provides for easiness of the product relocation by the staff,
- the additional control unit with monitor, installed on the infant module body, arranged
on the opposite side from the stand provides for control of basic functions of the
incubator - resuscitation system transformer with the deactivated basic control panel,
for example, at night time,
- the phototherapy device additionally installed on the stand increases a number of
procedures built-in into the product that are required for the neonate care,

[0014] The described design of mechanism of the incubator-resuscitation system for the newborn
allows to quickly transform the incubator into resuscitation system and back, herewith,
the product provides for accurate temperature condition controlled by the processor,
the preset humidity, temperature against air and baby's skin are automatically maintained,
the weight is measured, the mattress slope and infant module height are adjusted.
The incubator hood is made in dome form, without angles, thus increasing the easiness
of visualization without distortions of the neonate condition from any location of
the medical staff.
[0015] The proposed inventions are explained by the drawings with the following representations:
Fig. 1 - Front view of the incubator-resuscitation system with closed hood (product
operates as an incubator),
Fig. 2 - Right view in Fig. 1,
Fig. 3 - Front view of the incubator-resuscitation system with open hood (product
operates as a resuscitation system),
Fig. 4 - Right view in Fig. 3.
[0016] The mechanism of incubator-transformer for the newborn contains the infant module
1 (Fig. 1, 2) installed on transport trolley 2 (Fig. 1, 2, 3, 4), stand 3 with IR-emitter
4, illumination device 5 and control unit 6 with monitor 7 that is performed with
sensor screen and additional local illumination source 8, equipment connection module
9, boxes 10 for accessories storage. The compartment for a neonate is formed at installation
of the hood 11 onto the infant module 1. The hood 11 is made dome-shaped (Fig. 2)
with the lateral sides as a unified structure in form of the half of the horizontally
orientated cylinder with ball segments on the ends (Fig. 1). The hood 11 is divided
in longitudinal axis into two parts 12 and 13 (Fig. 2, 4) which of them is installed
in articulated manner on parallel axes 14 and 15 (Fig. 1, 3) in the infant module
body 1. On lateral surfaces of the hood 11 there are symmetrically performed six windows
16 with doors 17 on each. Two windows 16 are made on doors 18 and 19 installed with
hinges in the windows of bigger size, that are made to provide for a possibility to
take a neonate out from the incubator with the closed hood 11. On the infant module
body 1, from the opposite side from the stand 3 there is installed an additional control
unit 20 with monitor 21 as well as a handrail 22 for the product relocation. On transport
trolley 2 there are mounted the pedals 23 that duplicate the product height adjustment
control and also the castors 24 for the product relocation. So, control of the product
transformation from incubator-transformer into resuscitation system and vice versa
and also control of the product height adjustment can be made on monitor 7 and additional
control unit 20. On stand 3 there is additionally installed a phototherapy device
25 and boxes 9 for accessories storage.
[0017] The proposed method of transformation of the incubator for the newborn into resuscitation
system is to be carried out in the following sequence. When touching a respective
button on monitor 7 display there will be switched on the control unit 6 of the hood
11 relocation mechanism of infant module 1 and the hood 11 will starts relocating
at simultaneous switch on of IR-emitter 4. The hood 11 divided in longitudinal plane
into two parts 12 and 13 starts rotation around the parallel axes 14 and 15 installed
on both sides of infant module 1 and on which the hood parts 12 and 13 respectively
are installed relocating under the infant module 1 body. At night time when the control
unit with monitor 7 is switched off the control of the hood 11 relocation is made
by pressing the button on the monitor control system 21. At occurrence of situations
dangerous for a neonate the monitor 7 will automatically switch on and on its screen
there will be displayed the information on the patient state and the equipment operation.
[0018] The devices operate as follows.
1. Incubator for the newborn.
[0019] The test system with micro processor monitoring control of the incubator operation
parameters will be connected to the power source. The monitoring parameters values
(temperature against air, temperature against skin, relative humidity, oxygen concentration,
neonate mass etc) will be output to the monitor 7 of the control 6 and display unit
placed on the incubator. The baby will be placed in the infant module 1. The incubator
for the newborn automatically provides the adjustable heat gain, required air humidity
and concentration of oxygen in infant module 1, body mass control.
[0020] The thermotherapy will be made by means of maintaining the present temperature of
air inside infant module 1 of the incubator with adjustment of air temperature of
patient's skin temperature, provision with required humidity of air, oxygen therapy
by adjusting the air saturation with oxygen, infant module 1 slope adjustment to ensure
the low or high position of the head. Standard or intensive care will be made by opening
the doors for hands in the windows 16 or lateral doors 18 and 19 of the windows of
larger size.
[0021] Moreover, when required, the following activities of intensive therapy will be carried
out:
- blood transfusion,
- dosed administration of medical solutions,
- aspiration from upper airways,
- artificial ventilation of lungs,
- phototherapy,
- X-ray.
[0022] The following parameters are output to the monitor 7:
- air temperature,
- skin temperature (two sensors),
- air relative humidity,
- O2 concentration,
- body mass,
- SPO2 measurement,
- arterial pressure measurement,
- CO2 measurement.
[0023] The incubator is provided with internal memory allowing to record all monitored parameters
during seven days and output the trends to the monitor 7.
2. Resuscitation system.
[0024] During the incubator-transformer transformation into resuscitation system the IR-emitter
4 is automatically switched on for maintaining the temperature preset by medical staff.
The necessary resuscitation activities will be carried out, and then, as required,
by touching the button of sensor monitor 7 the resuscitation system within several
seconds will be transformed into the incubator.
[0025] The realization of the claimed group of inventions is made with the use of progressive
methods from high quality materials. All basic elements of design (hood, doors, infant
module body, stand, boxes for accessories storage etc) are made with the use of the
following technologies: plastic material pressure casting, stamping, mechanical treatment.
During the product mounting they use mechanical assembly, electrical wiring and checkout.
[0026] During the infant module assembly the labor intensiveness of its manufacture has
decreased, because, as compared with a prototype, there are removed the operations
for installation of lateral panels and their checkout when installing onto the infant
module 1 body. Each half 12 and 13 of the hood 11 is made by casting from high quality
plastic as a single piece.
[0027] So, the use of the claimed technical solutions in the product improves its technological
effectiveness of manufacture, permits to sufficiently increase the performance values
of the incubator-resuscitation system for the newborn, including the easiness of maintenance,
control and survey of the patients care modes, provision with hygienic requirements
as well as is in compliance with the modern ergonomic requirements. Hereat, there
are excluded the manual operations of the attending staff for a full access to the
patient and stay of the hood over the patient during the product transformation into
the open resuscitation system.
