[0019] It also includes an air pump 16 and a timer 17. The air pump 16 is connected to the first air charging pipe port 10 and the second air charging pipe port 11 through a pipeline, and the timer 17 is electrically connected to the air pump 16, the air charging valve 15 and the air exhaust valve 14 respectively.
[0020] In this embodiment: when the patient lies on his back, the neck support groove 3 on the protrusion 2 can support the patient's cervical spine, which is easy for the patient's shoulders to release pressure when lying on their back, and the head support groove 4 assists in limiting the head and gives the head a braking effect, which is easy for the patient to maintain a supine position;
[0021] A plurality of long airbag strips 5 and a plurality of short airbag strips 6 are arranged inside the head supporting groove 4. The power plug of the air pump 16 is plugged into the timer 17. The timer 17 controls the start and operation of the air pump 16 by powering on and off. Both the air charging valve 15 and the air exhaust valve 14 adopt normally closed solenoid valves. The timer 17 controls the opening and closing of the air charging valve 15 and the air exhaust valve 14 by powering on and off.
[0022] The timer 17 energizes the inflation pump 16 and the inflation valve 15 on the first inflation pipe port 10, and the gas enters the long airbag strip 5 through the first inflation layer 7. The multiple long airbag strips 5 support the patient's head, and there are gaps between the multiple long airbag strips 5, which makes it easy for the patient's head to ventilate where it is not in contact with the long airbag strips 5 and avoid squeezing. After the long airbag strips 5 support for a period of time, the timer 17 energizes the exhaust valve 14 on the first exhaust pipe 12, and the first exhaust pipe 12 opens, which makes it easy for the gas in the long airbag strips 5 to flow out, and then the patient is inhaled again. The inflation pump 16 and the inflation valve 15 on the second inflation pipe mouth 11 are energized to allow the gas to enter the short airbag strip 6 through the second inflation layer 8. The short airbag strip 6 and the long airbag strip 5 are arranged alternately to change the position of supporting the head. After supporting for a period of time, the exhaust valve 14 on the second exhaust pipe 13 is energized, and the second exhaust pipe 13 is opened to facilitate the outflow of gas from the short airbag strip 6; the long airbag strip 5 and the short airbag strip 6 alternately support the patient's head in turn, which is not easy to cause pressure sores on the occipital skin, and the supporting time can be set by the timer 17.
[0023] As a technical optimization solution of the present invention, a groove 18 is provided on the top of the pillow component 1 along the length direction, and the groove 18 is located behind the protrusion 2.
[0024] In this embodiment, the groove 18 facilitates heat dissipation at the bottom of the head and neck, thereby preventing the head and neck from sweating.
[0025] As a technical optimization solution of the present invention, a first through hole 19 is opened inside the neck support groove 3 .
[0026] In this embodiment, the inside of the neck supporting groove 3 is breathable, thereby enhancing the comfort performance of the neck.
[0027] As a technical optimization solution of the utility model, a second through hole 20 is opened inside the head supporting groove 4, and ventilation holes 21 are opened on both sides of the pillow component 1. The first through hole 19 and the second through hole 20 are connected to the ventilation holes 21.
[0028] In this embodiment, the air holes 21 are easy to let in air, thereby enhancing the overall air permeability of the pillow component 1.
[0029] As a technical optimization solution of the utility model, the pillow component 1 is a sponge-like foam made of polyurethane material.
[0030] In this embodiment: the sponge-like foam is made of polyurethane material, which has high comfort, increases the comfort of the user, and reduces the formation of pressure sores on the pillow skin.
[0031] Working principle: First, the timer 17 energizes the inflation pump 16 and the inflation valve 15 on the first inflation pipe port 10, and the gas enters the long airbag strip 5 through the first inflation layer 7. The multiple long airbag strips 5 support the patient's head, and there are gaps between the multiple long airbag strips 5, which makes it easy for the patient's head to ventilate where it is not in contact with the long airbag strips 5 and avoid squeezing. After the long airbag strips 5 support for a period of time, the timer 17 energizes the exhaust valve 14 on the first exhaust pipe 12, and the first exhaust pipe 12 opens, which makes it easy for the patient to breathe. The gas in the long airbag strip 5 flows out, and the inflation pump 16 and the inflation valve 15 on the second inflation pipe mouth 11 are energized again, so that the gas enters the short airbag strip 6 through the second inflation layer 8. The short airbag strip 6 and the long airbag strip 5 are arranged alternately to change the position of supporting the head. After supporting for a period of time, the exhaust valve 14 on the second exhaust pipe 13 is energized, and the second exhaust pipe 13 is opened, which makes it easy for the gas in the short airbag strip 6 to flow out; the long airbag strip 5 and the short airbag strip 6 alternately support the patient's head, which is not easy to cause pressure sores on the occipital skin.
[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
