Detailed Implementation

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] An integrated pressure-relief pad for preventing back and buttock injuries includes a back airbag assembly 1 and a buttock fluid cushion 2. A connecting structure 3 is provided between the back airbag assembly 1 and the buttock fluid cushion 2 to fix the back airbag assembly 1 and the buttock fluid cushion 2 into one unit. The connecting structure 3 is provided with straps or buckles to fix the pressure-relief pad to the backrest and seat area of ​​the wheelchair. The back airbag assembly 1 includes multiple interconnected airbag units, which are stacked along the longitudinal direction of the back to adapt to the back curve. Each airbag unit is provided with an inflation / deflation port 11, and a sealing cover 12 is provided on the inflation / deflation port 11. The buttock fluid cushion 2 is filled with a highly fluid medium, and the exterior of the buttock fluid cushion 2 is a flexible sealing structure. Two sets of pressure relief grooves 21 are symmetrically arranged on the buttock fluid cushion 2.

[0016] In use, the back airbag assembly 1 is connected and fixed to the hip fluid cushion 2 via the connecting structure 3. The pressure-reducing pad is then fixed to the backrest and seat area of ​​the wheelchair via straps or buckles on the connecting structure 3. The sealing cap 12 is then unscrewed, and the back airbag assembly 1 is inflated through the inflation / deflation port 11, providing the patient's back with a close-fitting and pressure-distributing support. The inflation / deflation port 11 inflates or deflates the airbag unit of the back airbag assembly 1 to adjust the expansion degree of the airbag unit, allowing it to better adapt to the back curves of different users, thereby providing support to the back. It provides effective support and pressure relief; the patient's buttocks naturally sit on the buttock fluid cushion 2, and the fluid medium dynamically flows with the pressure on the buttocks to achieve uniform pressure distribution. Two sets of pressure relief grooves 21 are located at the patient's buttocks, which can improve the patient's comfort while achieving the purpose of pressure relief. During long-term use, the inflation volume of the back airbag can be finely adjusted at any time according to the patient's body posture or pressure perception to maintain the best pressure relief effect, achieve integrated pressure relief of the back and buttocks, effectively prevent pressure injuries in wheelchair patients, and has the advantages of reasonable structure, convenient use, and significant pressure relief effect.

[0017] As a possible implementation of this solution, preferably, the connecting structure 3 includes a connecting seat 31, a movable support 32 is rotatably connected to one side of the connecting seat 31, the movable support 32 is fixedly connected to the side wall of the buttock fluid cushion 2, a U-shaped card seat 35 is installed on the connecting seat 31, the U-shaped card seat 35 is installed on the bottom outer side of the back airbag assembly 1, and the two sides of the U-shaped card seat 35 abut against the two sides of the movable support 32.

[0018] The U-shaped bracket 35 and the movable support 32 abut against each other, ensuring the stability of the connection between the two, while facilitating the assembly and disassembly of the back airbag assembly 1 and the hip fluid cushion 2, enabling quick installation and disassembly.

[0019] As a possible implementation of this solution, preferably, guide holes 33 are symmetrically arranged on both sides of the top of the connecting seat 31, and guide rods 13 are arranged on both sides of the bottom of the back airbag assembly 1 corresponding to the guide holes 33, and one side of the back airbag assembly 1 is tightly fitted with the movable support 32.

[0020] The guide hole 33 on the connector 31 cooperates with the guide rod 13 at the bottom of the back airbag assembly 1, which plays a guiding and positioning role in the installation of the back airbag assembly 1, ensuring the accuracy of the connection between the back airbag assembly 1 and the connector 31, while enhancing the stability of the connection between the two and preventing the back airbag assembly 1 from shaking during use.

[0021] As a possible implementation of this solution, preferably, threaded holes 34 are symmetrically arranged on both sides of the movable support 32, and bolts 36 are arranged on both sides of the U-shaped bracket 35 corresponding to the threaded holes 34, so that the U-shaped bracket 35 clamps the back airbag assembly 1 from the side opposite to the movable support 32 through the bolts 36.

[0022] The threaded holes 34 on both sides of the movable support 32 cooperate with the bolts 36 on both sides of the U-shaped bracket 35. By tightening the bolts 36, the U-shaped bracket 35 can clamp the back airbag assembly 1 from the side opposite to the movable support 32, which further strengthens the connection between the back airbag assembly 1 and the connecting structure 3, prevents the back airbag assembly 1 from loosening or falling off during use, and ensures the stability of the decompression effect.
