Abstract
Description
Technical Field
[0001] The utility model relates to daily necessities for human beings, in particular to medical equipment, and more particularly to a headrest for preventing pressure damage to the occipital region. Background Art
[0002] Pressure injuries, also known as pressure sores, often occur on bony protrusions of the body. Pressure injuries can cause pain, infection, prolonged hospitalization, increased mortality, loss of body image, and increased treatment costs.
[0003] Infants and young children generally refer to children under 3 years old. Since they are still in a special developmental stage, their heads, especially the occipital region, have less hair and lack the protection of fat tissue, making their heads particularly sensitive to pressure. At the same time, the younger the child, the greater the proportion of head weight to body weight, which can reach 25% for newborns. The proportion of head weight to body weight in infants and young children is also much greater than that of an ordinary adult. Therefore, when infants and young children maintain a supine position for a long time, the occipital region of infants and young children is very prone to pressure injuries, especially after surgery. Due to factors such as mechanical ventilation and the use of sedatives, infants and young children are unable to change their body position independently and will remain in a supine position for a long time, which greatly increases the probability of pressure injuries to the occipital region of infants and young children.
[0004] Products used to prevent pressure injuries in the prior art, such as Figure 1 As shown, or for example, CN203663020U (anti-pressure sore circulating air cushion device), CN209187311U (a cooling and comfortable pillow for preventing and improving pressure sores), etc., mainly reduce the pressure on the pillow by changing the hardness of the pillow support, but cannot substantially change the pressure point. Especially for infants and young children, if the pressure point cannot be adjusted, maintaining a supine position for a long time will still cause pressure injuries to the pillow.
[0005] On the other hand, when infants and young children use other products, such as water pillows, hydrocolloid dressings, and foam dressings, nurses need to regularly remove the dressings to inspect the infant's or young child's occipital region. This can cause pain and can also lead to occipital baldness. When using water pillows and pressure-reducing dressings, the infant's or young child's occipital region is elevated, hindering airway patency. Utility Model Content
[0006] The purpose of the present utility model is to provide a headrest for preventing pressure injuries to the occipital region. The headrest for preventing pressure injuries to the occipital region is intended to solve the technical problem in the prior art that existing headrests cannot prevent pressure injuries by adjusting the pressure points.
[0007] In order to achieve the above purpose, the present invention provides the following technical solutions:
[0008] A headrest for preventing occipital pressure injuries comprises four airbags, a console and an air source, wherein the four airbags are connected end to end in a ring; a controller is provided in the console, and a command input device is connected to the input end of the controller; each of the airbags is connected to the air source via an inflation pipe, and each of the inflation pipes is provided with a ventilation solenoid valve, and the control end of each ventilation solenoid valve is communicatively connected to the output end of the controller; each of the airbags is also connected to an exhaust device.
[0009] Furthermore, the exhaust device is an exhaust solenoid valve, the control end of the exhaust solenoid valve is communicatively connected to the output end of the controller, the air inlet end of the exhaust solenoid valve is connected to the inner cavity of the corresponding airbag, and the air outlet end of the exhaust solenoid valve is connected to the outside world.
[0010] Furthermore, the command input device is a control button.
[0011] Furthermore, an electronic barometer is provided in each of the airbags or the inflation pipe, and the signal output end of each of the electronic barometers is electrically connected to the input end of the controller.
[0012] Furthermore, a display screen is provided on the console, and an input end of the display screen is communicatively connected to an output end of the controller.
[0013] Furthermore, any one of the airbags is in the shape of a quarter of a circular ring, and the four airbags are connected by gluing.
[0014] Alternatively, the outside of any one of the airbags is covered with a pillowcase, and the bases of any two adjacent pillowcases are connected by a zipper.
[0015] Working principle: By adjusting the air pressure to achieve the pressure of the airbag in different directions, the airbag can drive the patient's head to rotate. By preventing the pressure point on the patient's head from staying in the same position for a long time, the probability of pressure injury to the patient's head is reduced.
[0016] Compared with the prior art, the beneficial effect of the present invention is that it enables the patient's head to rotate within a controllable range, thereby preventing the patient from lying on his back for a long time and causing pressure damage to the head.

[0019] Example 1
[0020] See also Figure 2 , the utility model provides a technical solution:
[0021] A headrest for preventing occipital pressure injuries comprises four airbags 1, a console 2, and an air source (not shown). The four airbags 1 are connected end to end in a ring. The console 2 is provided with a controller (not shown), and the input end of the controller is connected to a command input device 3. The command input device 3 receives at least four input commands, namely, to inflate airbags A, B, C, and D respectively. The command input device 3 is a control button. Each airbag 1 is connected to the air source via an inflation pipe 4. Each inflation pipe 4 is provided with a ventilation solenoid valve (not shown). The control end of each ventilation solenoid valve is communicatively connected to the output end of the controller. Each airbag 1 is also provided with an exhaust device (not shown).
[0022] The control buttons are physical buttons, which can prevent accidental touches.
[0023] Example 2
[0024] The difference between Example 2 and Example 1 is that the exhaust device is an exhaust solenoid valve, the control end of the exhaust solenoid valve is communicatively connected to the output end of the controller, the air inlet end of the exhaust solenoid valve is connected to the inner cavity of the corresponding airbag 1, and the air outlet end of the exhaust solenoid valve is connected to the outside world.
[0025] By operating the command input device 3 , the exhaust solenoid valve can be made to exhaust the air in the airbag 1 .
[0026] Example 3
[0027] The difference between Example 3 and Example 1 is that each airbag 1 is provided with an electronic barometer, the signal output end of each electronic barometer is electrically connected to the input end of the controller, and a display screen is provided on the console 2, and the input end of the display screen is communicatively connected to the output end of the controller.
[0028] The electronic barometer reading and the current mode of the device (decompression mode, steering mode, airway mode, etc.) can be displayed on the display screen, making it easier for medical staff to make decisions and adjust the air pressure independently.
[0029] The structure of this embodiment is combined with the exhaust solenoid valve in embodiment 2, so that the air pressure in the four airbags can be adjusted more freely.
[0030] Example 4
[0031] The difference between Example 4 and Example 1 is that each airbag 1 is in the shape of a quarter of a circular ring, and the four airbags 1 are connected by gluing.
[0032] Example 5
[0033] The difference between Example 5 and Example 1 is that the outside of any airbag 1 is covered with a pillowcase, and the bases of any two adjacent pillowcases are connected by a zipper.
[0034] The structure of this embodiment is more conducive to improving the comfort of patients.
[0035] The controller 3 includes a processor and input / output circuits. Specifically, the processor and the input / output circuits are integrated into a single chip microcomputer, such as the MEGA32 chip of ARM.
[0036] The controller 3, electronic barometer, ventilation solenoid valve, exhaust solenoid valve, control buttons, processor and input and output circuits, and single-chip microcomputer described in the above embodiment all adopt well-known solutions in the prior art, which are already understood by those skilled in the art and will not be described in detail here.
[0037] The working process of this embodiment:
[0038] Place the airbags in a ring shape on the lower side of the patient's head. Figure 2 The four airbags 1 are distinguished by their positions and named as airbag A, airbag B, airbag C, and airbag D. By manipulating the controller 3 and opening the ventilation solenoid valve 5, the four airbags 1 can be inflated separately, and by opening the exhaust solenoid valve, the four airbags can be exhausted separately. The independent inflation and exhaust operations of the four airbags can make the four airbags produce the same or different air pressures, which are recorded as PA, PB, PC, and PD, corresponding to airbag A, airbag B, airbag C, and airbag D respectively. At this time, the different air pressure relationships will make each airbag 1 produce a different support height, thereby pushing the patient's head to produce different postures in the three-dimensional direction, which is specifically manifested as follows:
[0039] Decompression mode: PA=PB=PC=PD, keeping the head suspended in a decompression state; this state can provide balanced support for the head of a patient lying flat. If PA, PB, PC, and PD are reduced at the same time, airbags A, B, C, and D will become softer simultaneously, increasing the contact area with the patient's head and achieving a decompression effect;
[0040] Airway mode: At this time, PB and PC are greater than PA and PD, which can keep the airway open. At this time, the patient's head can be controlled to lift in the length direction to keep the airway open.
[0041] Turning mode (left turn): PA, PB> PC, PD, the pressure part can be adjusted; the pressure of each part of the head can be balanced to prevent a certain part from being subjected to excessive pressure or too strong pressure;
[0042] Steering mode (turn right): At this time, PA and PB are less than PC and PD, and the pressure part can be adjusted; at this time, the pressure of various parts of the head can be balanced to prevent a certain part from being subjected to excessive and strong pressure.
[0043] Different modes can be adjusted according to the doctor's surgical needs to assist in surgery and reduce long-term pressure on the patient's head, resulting in redness or skin pressure damage.
[0044] When the headrest is not needed, the air in the four airbags 1 can be emptied through the exhaust solenoid valve or by removing the inflation pipe 4 from the airbag 1.
[0045] The device, operated by medical staff through a command input device, can assist with adjustments when the patient is unable to control head movement without interfering with the patient's connected tubes. When infants and young children are in the prone position, the gap between the two airbags can be adjusted as needed using a zipper, facilitating the placement of endotracheal tubes and other catheters while the infant is in the prone position.
[0046] Specifically, the pillowcase is used to absorb the patient's sweat and improve the patient's comfort.
[0047] Specifically, this device can be mainly used for infants and young children to help them turn their heads while lying in bed, preventing pressure injuries to their occipital region. This device can also be used as a pillow for adults, or to assist in supporting other parts of the body to prevent pressure injuries.
