Description

Technical Field

[0001] This invention relates to the field of prone ventilation technology, and particularly to a prone ventilation support. Background Technology

[0002] Prone ventilation is a respiratory medicine term published in 2018. Mechanical ventilation performed in the prone position is an adjunct measure for treating acute respiratory distress syndrome. Its mechanism utilizes gravity to increase blood flow to the anterior chest and ventilation in the back, improving gas exchange. However, when the patient is in the prone position, the head and shoulders are unsupported, and maintaining the prone position for a long time can easily cause fatigue and discomfort. Chinese patent (publication number: CN115192340A) discloses a prone ventilation support, including a head support seat; the head support seat is provided with a support device A, and the side of the support device A away from the head support seat is a support surface A for supporting the patient's head.

[0003] However, existing prone ventilation supports still have some drawbacks in use, such as:

[0004] Existing prone ventilation supports use a head support to support the head and a shoulder support to support the shoulders. However, these supports provide support at two points, leaving the upper body partially suspended in the air. If this type of support is used for extended periods, the weight of the upper body will be concentrated on the shoulders and head. Maintaining this posture for a long time can cause excessive pressure on the head and shoulders, leading to soreness or even secondary injury. To address these problems, we propose a prone ventilation support. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a prone ventilation support to solve the problem that existing support seats support the head and shoulders at two points, causing the upper body to be semi-suspended in the air. If such a support seat supports the body for a long time, it will cause the weight of the upper body to be concentrated on the shoulders and head. Maintaining this posture for a long time will cause excessive pressure on the head and shoulders, resulting in soreness or even secondary injury.

After the head support device 300 is inflated, the three diversion channels in the three-way air tube 103 are controlled by the switch control device 200. When the user presses the topmost press switch 205, the lever 204 descends and exerts force on the buckle plate 202. Under the pressure of the lever 204, the buckle plate 202 descends along the slope in the irregular groove. Finally, one end of the lever 204 falls into the irregular groove and then springs back to lock. When lever 204 is pressed down, one end of lever 204 presses against the upper shunt tube of the three-way airway 103, which closes the upper shunt tube of the three-way airway 103. The head support device 300 will no longer be filled with gas. Similarly, the other shunt tubes in the three-way airway 103 can be controlled. At the same time, when one lever 204 is pressed down, the buckle plate 202 descends, and the other levers 204 that are locked in the irregular slots can be popped out by the rebound force of the pressing spring 206. The head support device 300, the first hump airbag 401 and the second hump airbag 501 are filled with different amounts of gas, which can support the patient and provide a more comfortable prone ventilation position.
