Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an anti-slip displacement air cushion. Background Technology

[0002] Medical air cushions are assistive medical devices specifically designed for medical settings, primarily used to improve patients' comfort while in bed, prevent complications, or assist in treatment. They are typically made of polymer materials forming an air bladder structure, achieving specific functions through inflation, deflation, or pressure adjustment. They are widely used in the care of long-term bedridden patients, post-operative recovery patients, or people with limited mobility.

[0003] In existing technologies, some patients need to place air mattresses on the bed board during their recuperation. Air mattresses can distribute body pressure and prevent pressure sores, making them especially suitable for patients who are bedridden for a long time. The flexible support of air mattresses reduces pressure on bony protrusions, improves bed comfort, and cushioning can relieve muscle fatigue.

[0004] However, during the use of air cushions, the lack of fixation can cause the air cushion to shift when the patient moves, and the patient may also unconsciously hit the edge of the air cushion, causing it to slide. This may not only cause the air cushion to deviate from its original support position and reduce the pressure distribution effect, but may also cause the patient's body to be partially suspended and unevenly stressed, increasing the risk of pressure sores. Therefore, we propose an anti-slip displacement air cushion. Utility Model Content

[0005] One of the technical problems this application aims to solve is: to prevent the air mattress from sliding freely on the bed frame by fixing it in place.

[0006] To address the aforementioned technical problems, this application provides an anti-slip displacement air cushion, including an anti-slip mechanism. A protective mechanism is provided on one side of the anti-slip mechanism. The anti-slip mechanism includes a bed board, with an air cushion body disposed on the top side of the bed board. The top side of the bed board contacts the bottom side of the air cushion body. A protrusion is provided on one side of the air cushion body, and this protrusion is fixedly connected to one end of the protrusion. A connecting rod is provided on one side of the protrusion, and this rod is fixedly connected to one end of the connecting rod. A collar is provided on the outer side of the other end of the connecting rod, and this collar fits into the inner side of the collar. An insertion rod is provided on the inner wall of the collar, and the inner wall of the collar is through-connected to the outer side of the insertion rod. One outer end of the insertion rod is perpendicularly engaged with the inner wall of the connecting rod.

[0007] In some embodiments, the protective mechanism includes a protective shell, one side of which contacts one side of the bed board, and a locking rod is provided on the inner wall of one side of the bed board. The inner wall of one side of the bed board is engaged with the outer side of the locking rod, and the outer side of the locking rod is fixedly connected to the inner wall of the bed board through it.

[0008] In some embodiments, a positioning plate is provided on the top side of the bed board, and the top side of the bed board is fixedly connected to the bottom side of the positioning plate. One side of the positioning plate contacts one side of the air cushion body. A crossbar is provided on the inner wall of the bed board. In some embodiments, a conical plate is provided at one end of the mother plate, and one end of the mother plate is fixedly connected to one side of the conical plate. A sub-rod is provided on the top side of the conical plate, and the top side of the conical plate rotatably contacts the bottom end of the sub-rod.

[0009] In some embodiments, a fixing rod is provided at the top of the cone plate, the top of the cone plate is fixedly connected to the bottom side of the fixing rod, and the bottom side of the fixing rod is fixedly connected to the top of the insertion rod.

[0010] In some embodiments, an inner plate is provided on the inner side of the crossbar, and the inner side of the crossbar is slidably connected to one end of the inner plate.

[0011] In some embodiments, the upper and lower sides of the inner panel are fixedly connected to the inner wall of the bed board.

[0012] The outer sliding connection.

[0013] In some embodiments, a handle is provided on one side of the crossbar, and one side of the crossbar is fixedly connected to one end of the handle. A knob is provided at the middle of the handle, and the middle of the handle is rotatably connected to the outer side of the knob. A mother plate is provided at the top of the knob, and the top of the knob is fixedly connected to one end of the mother plate.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. By pushing the crossbar, which has multiple collars, each collar corresponds to a connecting rod. Therefore, by pushing the crossbar, the collars move in their original positions, and at the same time, the collars fit into the outer side of one end of the connecting rod, preventing the air cushion body from moving back and forth on the bed board. By applying external force to the mother plate, the cone plate rotates slightly, allowing the insert rod to enter the connecting rod without any support. In this way, the air cushion body can be prevented from moving left and right on the bed board. The above method can achieve complete fixation of the air cushion body in the front, back, left and right directions on the bed board.

[0016] 2. By engaging the locking rod on the protective shell with the bed board, the protective shell and the bed board are structurally connected. This allows the anti-slip components to be covered by the protective shell when the user gets into bed, preventing the human body from directly contacting the mechanical structure of the anti-slip components and avoiding deformation of the anti-slip components due to pressure.

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.

[0026] Example 1: Please refer to Figure 1 - Figure 6This utility model provides a technical solution: an anti-slip displacement air cushion, including an anti-slip mechanism 1, a protective mechanism 2 provided on one side of the anti-slip mechanism 1, the anti-slip mechanism 1 including a bed board 11, an air cushion body 12 provided on the top side of the bed board 11, the top side of the bed board 11 contacting the bottom side of the air cushion body 12, a protrusion 13 provided on one side of the air cushion body 12, one side of the air cushion body 12 being fixedly connected to one end of the protrusion 13, a connecting rod 14 provided on one side of the protrusion 13, and one side of the protrusion 13 being connected to the connecting rod 14. One end of the connecting rod 14 is fixedly connected, and the other end of the connecting rod 14 is provided with a collar 15 on the outer side. The other end of the connecting rod 14 is fitted and connected to the inner side of the collar 15. An insertion rod 18 is provided on the inner wall of the collar 15. The inner wall of the collar 15 is connected through to the outer side of the insertion rod 18. The outer side of one end of the insertion rod 18 is perpendicularly engaged with the inner wall of the connecting rod 14. A positioning plate 115 is provided on the top side of the bed board 11. The top side of the bed board 11 is fixedly connected to the bottom side of the positioning plate 115. One side of the positioning plate 115 contacts one side of the air cushion body 12. A crossbar 16 is provided on the inner wall of the bed board 11. The inner wall of the bed board 11 is slidably connected to the outer side of the crossbar 16. A handle 17 is provided on one side of the crossbar 16. One side of the crossbar 16 is fixedly connected to one end of the handle 17. A knob 111 is provided at the middle of the handle 17. The middle of the handle 17 is rotatably connected to the outer side of the knob 111. A mother plate 112 is provided at the top of the knob 111. The top of the knob 111 is fixedly connected to one end of the mother plate 112. A conical plate 113 is provided at one end of the mother plate 112. One end of the mother plate 112 is connected to the conical plate 113. One side of the plate 113 is fixedly connected. A sub-rod 110 is provided on the top side of the cone plate 113. The top side of the cone plate 113 is rotatably in contact with the bottom end of the sub-rod 110. A fixing rod 19 is provided at the top of the cone plate 113. The top of the cone plate 113 is fixedly connected to the bottom side of the fixing rod 19. The bottom side of the fixing rod 19 is fixedly connected to the top of the insertion rod 18. An inner plate 114 is provided on the inner side of the crossbar 16. The inner side of the crossbar 16 is slidably connected to one end of the inner plate 114. The upper and lower sides of the inner plate 114 are fixedly connected to the inner wall of the bed board 11.

[0027] When using this type of anti-slip displacement air cushion, firstly, multiple positioning plates 115 are installed on the bed board 11, with a certain gap between the multiple positioning plates 115. Therefore, by aligning the distance between the air cushion body 12 and the positioning plates 115, the air cushion body 12 is initially fixed. At the same time, the air cushion bodies 12 are connected by protrusions 13. Then, a connecting rod 14 is installed on one side of each of the multiple protrusions 13. At this time, a crossbar 16 designed inside the bed board 11 has multiple collars 15, each collar 15 corresponding to a connecting rod 14. Therefore, by pushing the crossbar 16, the collars 15 move in their original positions. At the same time, the collars 15 fit with the outer side of one end of the connecting rod 14, preventing the air cushion body 12 from moving back and forth on the bed board 11.

[0028] An insert rod 18 is provided on the inner wall of the top side of the collar 15. The top end of the insert rod 18 is fixed to the fixing rod 19. The fixing rod 19 has the same length as the crossbar 16. At the same time, a sub-rod 110 is designed on the bottom side of the middle end of the fixing rod 19. The bottom end of the sub-rod 110 contacts the cone plate 113. Therefore, by applying external force to the mother plate 112, the cone plate 113 is rotated slightly, and then the cone plate 113 is separated from the bottom end of the sub-rod 110. When the sub-rod 110 is not supported, the insert rod 18 and the fixing rod 19 move down synchronously, and the insert rod 18 enters the connecting rod 14. In this way, the air cushion body 12 cannot move left or right on the bed board 11. Therefore, the air cushion body 12 can be fully fixed in the front, back and left and right directions on the bed board 11 through the above method, effectively preventing its anti-slip displacement.

[0029] An inner plate 114 is designed inside the crossbar 16. The upper and lower sides of the inner plate 114 are fixed to the inner wall of the bed board 11, while the left and right ends are slidably connected to the inside of the crossbar 16. In this way, the crossbar 16 can slide without deviation in its path under the action of the inner plate 114, thereby ensuring that the collar 15 can accurately fit with the connecting rod 14.

[0030] Example 2: Please refer to Figure 1 - Figure 6 The protective mechanism 2 includes a protective shell 21. One side of the protective shell 21 contacts one side of the bed board 11. A locking rod 22 is provided on the inner wall of one side of the bed board 11. The inner wall of one side of the bed board 11 is engaged with the outer side of the locking rod 22. The outer side of the locking rod 22 is fixedly connected to the inner wall of the bed board 11 through it.

[0031] A protective shell 21 is designed on one side of the bed board 11. By locking the locking rod 22 on the protective shell 21 to the bed board 11, the protective shell 21 and the bed board 11 are structurally connected. In this way, when the user gets on the bed, the protective shell 21 can cover the anti-slip components, preventing the human body from directly contacting the mechanical structure of the anti-slip components. This avoids deformation of the anti-slip components after being pressed, which would prevent the structural fit from being completed effectively. It ensures that each component can cooperate precisely when the anti-slip components are fixed in the front-back and left-right directions.

[0032] Please see Figure 1 - Figure 6By aligning the distance between the air cushion body 12 and the positioning plate 115, the air cushion body 12 is initially fixed. At this time, the crossbar 16 designed inside the bed board 11 has multiple collars 15, each collar 15 corresponding to the connecting rod 14. Therefore, by pushing the crossbar 16, the collars 15 move in their original positions. At the same time, the collars 15 fit with the outer side of one end of the connecting rod 14, preventing the air cushion body 12 from moving back and forth on the bed board 11. Since there is an insert rod 18 designed on the inner wall of the collar 15, by moving the mother plate 112, the cone plate 113 no longer provides support to the sub-rod 110. The insert rod 18 and the fixing rod 19 move down simultaneously, and the insert rod 18 enters the connecting rod 14. In this way, the air cushion body 12 cannot move left or right on the bed board 11, and the air cushion body 12 can be controlled in all directions.

[0033] By engaging the locking rod 22 on the protective shell 21 with the bed board 11, the protective shell 21 and the bed board 11 are structurally connected. This allows the anti-slip components to be covered by the protective shell 21 during the user's ascent, preventing the human body from directly contacting the mechanical structure of the anti-slip components and avoiding deformation caused by pressure on the anti-slip components.
