Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] First embodiment:

[0034] like Figures 1-6 As shown, an airbag cushion for preventing pressure injuries includes a cushion assembly 10, an airbag assembly 20 installed inside the cushion assembly 10, an air delivery tube 40 installed on the cushion assembly 10, and an inflation tube 30 installed on the airbag assembly 20. The airbag assembly 20 is inflated and deflated through the inflation tube 30, thereby changing the pressure point on the skin and preventing pressure sores or pressure injuries.

[0035] The cushion 10 is circular, and the airbag assembly 20 is concentrically arranged with the cushion 10 and is surrounded inside the cushion 10.

[0036] Several sets of protrusions 11 are also fixedly provided along the end face of the soft pad 10 and the airbag assembly 20 for anti-slip purposes, etc.

[0037] Among them, such as Figure 1 As shown, the soft pad 10 also has a first notch 13 and a second notch 14 at both ends. The soft pad 10 can be opened through the notches 13 and 14 to remove the inner airbag assembly 20. A Velcro 15 is also installed on the front end face of the second notch 14. The front end face of the first notch 13 has a corresponding adhesive area (not shown in the figure) for the Velcro 15. The soft pad 10 is enclosed by attaching the Velcro 15 to this area.

[0038] Among them, such as Figure 2 As shown, to facilitate positioning of the airbag assembly 20, the airbag assembly 20 includes an airbag body 201 and a base 202, with the airbag body 201 inserted into the base 202, as shown. Figure 4 and Figure 6 As shown, a limiting plate 16 is also fixedly installed on the inner wall of the cushion 10. Two sets of limiting plates 16 are provided vertically. Limiting grooves 203 are formed between the upper and lower end faces of the base 202 and the limiting plates 16. The limiting plates 16 can be precisely engaged in the limiting grooves 203, thus restricting the airbag assembly 20 to a position as shown. Figure 1 In the direction shown, the inflation tube 30 should be connected to the airbag body 201. The end of the inflation tube 30 can be connected to an inflation device (not shown in the figure). The inflation device is equipped with inflation and deflation functions, which can realize the inflation and deflation of the airbag body 201. The inflation device is a product of the prior art, so it will not be described in detail here. In the first embodiment, the airbag is used to support the patient's head. By slowly inflating and deflating the airbag body 201, the pressure points in areas such as the skin behind the ear that are prone to pressure sores are changed, thereby preventing the occurrence of pressure sores and other problems.

[0039] Among them, such as Figure 1 As shown, the Velcro 15 is also provided with a corresponding clearance groove 15a to the inflation tube 30. The inflation tube 30 extends out from between the first notch 13 and the second notch 14 and passes through the clearance groove 15a.

[0040] Among them, such as Figure 3As shown, the ventilation of the skin area under pressure should also be considered, and for this purpose, a ventilation piece 12 is arranged at the junction of the soft cushion 10 and the air bag assembly 20, the ventilation piece 12 is mounted on the soft cushion 10, the ventilation piece 12 comprises a shell 121, a cavity 123 is arranged in the shell 121, and a ventilation hole 122 is arranged on the upper inclined surface of the shell 121, wherein the shell 121 is connected with the outlet of the air supply pipe 40, air is supplied through the air supply pipe 40, and the air is discharged from the ventilation hole 122, thereby improving the ventilation of the skin area under pressure and reducing the probability of pressure injury.

[0041] Second embodiment:

[0042] Different from the first embodiment, as shown in the figure, Figure 7 The soft cushion 10 comprises a circular portion and a long strip portion, the long strip portion can be used to accommodate the calf portion, and the air bag assembly 20 is arranged inside the circular portion and is mainly used to accommodate the heel portion to prevent the skin of the heel portion from being damaged by pressure, the principle of preventing pressure injury is the same as that of the first embodiment, the difference lies in the shape and the part acted on, and the shape is designed according to the part acted on.

[0043] Third embodiment:

[0044] Different from the first embodiment and the second embodiment, as shown in the figure, Figure 8 The soft cushion 10 is a cuboid, and a curved surface corresponding to the shape of the sacrum portion is arranged on the upper end surface of the soft cushion 10, two groups of air bag assemblies 20 are mounted in the curved surface and act on the sacrum with less fat.

[0045] The mounting and dismounting processes between the air bag assembly 20 and the soft cushion 10 in the above three embodiments are the same, and the contained components are consistent.

[0046] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
