[0033] Please see Figure 1 - Figure 5 An air cushion structure for preventing pressure injury to the coccyx and sacrum during surgery includes a connecting plate 100, an inflation component 200, and a protective component 300.

[0034] Please refer to the details. Figure 1 An air cushion 110 is provided on the top of the connecting plate 100.

[0035] Please see Figure 2 - Figure 5 The inflation assembly 200 includes several sealing strips 210 disposed inside the air cushion 110. Several delivery pipes 220 are sealed and connected to the bottom of the air cushion 110. The bottom of each delivery pipe 220 passes through a connecting plate 100 and is sealed and connected to an electric valve 230. The bottom of each electric valve 230 is sealed and connected to a delivery ring 240. One side of the delivery ring 240 is sealed and connected to an air supply pipe 250. One side of the air supply pipe 250 is sealed and connected to a connector 260.

[0036] In one specific embodiment, the connector 260 allows the user to connect it to an external inflation / inhalation device and inflate the connector 260. The gas then enters the gas delivery pipe 250 and the delivery ring 240 through the connector 260. The user can press one of the control buttons 600 to open two corresponding electric valves 230, allowing gas to enter the air cushion 110. After being isolated by the sealing strip 210, four chambers are formed within the air cushion 110. Gas is inflated through two of the electric valves 230, causing two chambers to expand preferentially. Pressing the other control button 600 inflates the remaining chamber. After expansion, the electric valve 230 is closed, allowing the patient's sacrum to be supported within the groove, preventing pressure sores. When gas needs to be expelled, it can be extracted using the external inflation / inhalation device, thus avoiding pressure injuries.

[0037] Please see Figure 3 - Figure 4 The protective component 300 includes a fixing ring 310 with the color on the bottom of the connecting plate 100, a plurality of barbed hook and loop fasteners 320 on the top of the air cushion 110, a rough hook and loop fastener 330 attached to the top of each of the barbed hook and loop fasteners 320, and a soft pad 340 on the top of each of the rough hook and loop fasteners 330.

[0038] In one specific embodiment, the provided soft pad 340 allows other parts of the patient to come into contact with it during use, providing support and enhancing patient comfort. It also allows the soft pad 340 to be easily removed for cleaning using the combination of the hook and loop fasteners 330 and serrated hook and loop fasteners 320, avoiding the hassle of washing. Furthermore, the retaining ring 310 engages with the connecting plate 100, allowing the user to lean against the connecting plate 100 after the gas in the air cushion 110 is released, preventing the user from damaging the electric valve 230 or other air tubes due to the released gas. This achieves dual protection for the patient's body and other components.

[0039] Please see Figure 1 The outer wall of the fixing ring 310 is provided with a ventilation opening, and the interior of the connecting plate 100 is provided with several ventilation holes.

[0040] In one specific embodiment, the provided ventilation openings facilitate ventilation of the patient's coccyx and sacrum when the air cushion 110 lifts the patient up, thus avoiding discomfort caused by poor ventilation in the coccyx and sacrum and improving comfort.

[0041] Please see Figure 1A connecting line 400 is provided on one side of the fixing ring 310, and a connecting block 500 is provided on one side of the connecting line 400. Two control buttons 600 are provided on the top of the connecting block 500.

[0042] In one specific embodiment, the connecting block 500 facilitates the support and fixation of the top control button 600 and the bottom controller, making them more stable during use and preventing shaking.

[0043] Please see Figure 1 The soft pad 340 is made of medical-grade silicone, and the air cushion 110 has a groove in the middle, with a groove length of 13 cm.

[0044] In one specific embodiment, the presence of medical-grade silicone allows the cushion 340 to be made softer during use, thus enhancing patient comfort. Additionally, the groove allows the user's coccyx to be suspended in the air.

[0045] Please see Figure 2 - Figure 5 The outer wall of connector 260 is interlocked with retaining ring 310.

[0046] In one specific embodiment, the fixed ring 310 facilitates the support and fixation of the top part and protects the bottom part of the connecting plate 100, preventing damage to it.

[0047] Please see Figure 1 The air cushion 110 is made of polyurethane, and the bottom of the connecting block 500 is equipped with a controller.

[0048] In one specific embodiment, the presence of polyurethane allows for the utilization of its excellent sealing properties during use, effectively preventing air leakage and improving sealing performance.

[0049] Please see Figure 1-5 The electric valve 230 and the control button 600 are both electrically connected to the controller, which is electrically connected to an external power supply.

[0050] In one specific embodiment, a controller is provided to facilitate power supply control of electrical equipment, enabling the equipment to be powered on when needed, thus avoiding situations where power cannot be supplied when power is required.

[0051] In use, the user first connects to an external inflation / inflation device via the connector 260. Inflation of the connector 260 involves the gas entering the gas delivery pipe 250 and then the delivery ring 240. Pressing one of the control buttons 600 opens two corresponding electric valves 230, allowing gas to enter the air cushion 110. After being isolated by the sealing strip 210, four chambers are formed within the air cushion 110. Gas then inflates two of these chambers through two of the electric valves 230, causing them to expand preferentially. Pressing the other control button 600 inflates the remaining chamber. After expansion, the electric valve 230 is closed, allowing the patient's sacrum to be supported within the groove. To prevent pressure sores, when gas needs to be released, an external inflation / inflation device can be used to extract the gas, thereby avoiding pressure injuries. The included soft pad 340 allows other parts of the patient to contact the pad during use, providing support and comfort. The pad 340 can be easily removed for cleaning using the hook and loop fasteners 330 and serrated fasteners 320, avoiding the hassle of washing. The retaining ring 310 engages with the connecting plate 100, allowing the user to lean against the connecting plate 100 after the gas in the air cushion 110 is released, preventing damage to the electric valve 230 or other air tubes from the released gas. This provides dual protection for the patient and other components.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
