Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, and more particularly to a heel part anti-pressure injury lifting device. BACKGROUND

[0002] Patients who are in bed for a long time are prone to pressure sores, especially in the heel and other bony protuberance parts, because the local skin is under pressure for a long time. Pressure sores, also known as pressure ulcers or bedsores, are a phenomenon of tissue ulceration and necrosis caused by long-term pressure on local tissues, resulting in persistent ischemia, hypoxia, and malnutrition. For patients who are in a coma or have hemiplegia and are in bed for a long time, the heel and other parts that lack muscle and fat protection are more susceptible to pressure, thereby causing pressure sores. Pressure sores not only increase the patient's pain and the burden on the family and society, but also may even threaten the patient's life. Therefore, preventing and treating pressure sores is an important task in the care of patients who are in bed for a long time.

[0003] In the prior art, one of the common methods to avoid pressure sores in the heel due to long-term compression is to use a pillow or other soft cushion to elevate the foot. Although this method can reduce the pressure on the heel to some extent, the fixing effect is often not good, and the pillow or soft cushion is easily displaced, thereby losing the effect of elevating the foot. In addition, the pillow or soft cushion has a relatively single function and can only provide a basic elevating effect, and cannot simultaneously have the effect of preventing foot drop.

[0004] Therefore, it is necessary to make further improvements in the prior art. SUMMARY

[0040] The following describes in detail, with reference to the accompanying drawings, the heel support device for preventing pressure injuries according to an embodiment of the present invention.

[0041] Reference Figures 1 to 11 As shown, a heel support device for preventing pressure injuries according to an embodiment of the present invention includes a support plate 10, a leg pad 20, a locking member 13, a baffle, a palm pad 40, and an adjustment component 32.

[0042] The upper surface of the tray 10 is provided with a first mounting groove 11, and the front end of the tray 10 is provided with an extension plate 12.

[0043] The leg pad 20 is detachably disposed within the first mounting groove 11 for placing the patient's lower leg. The upper surface of the leg pad 20 is made of a flexible material and conforms to the contour of the human lower leg. It should be noted that the upper ends of both sides of the first mounting groove 11 have an inwardly protruding structure, meaning that the leg pad 20 needs to be inserted into the first mounting groove 11 from the rear end of the support plate 10 during installation. The front end of the first mounting groove 11 also protrudes upward to limit the insertion depth of the leg pad 20.

[0044] The locking member 13 is disposed in the first mounting groove 11 to lock the leg pad 20 in the first mounting groove 11.

[0045] The baffle is located at the front end of the extension plate 12 and forms an accommodating gap between the support plate 10 and the baffle. The baffle and the extension plate 12 are arranged perpendicularly, and a third mounting groove 31 is provided on the rear side of the baffle.

[0046] The palm pad 40 is disposed in the third mounting groove 31, and its lower end is rotatably connected to the third mounting groove 31 to fit the patient's foot.

[0047] The adjustment component 32 is located on the upper end of the front side of the baffle, and one end is connected to the upper end of the palm pad 40 to adjust the angle of the palm pad 40.

[0048] Based on the above, the leg pad 20 supports the patient's lower leg, allowing the heel to rest naturally within the accommodating gap formed by the support plate 10 and the baffle. This effectively avoids direct pressure on the heel, significantly reducing the risk of pressure injury caused by prolonged compression. The synergistic effect of the leg pad 20 and the foot pad 40 provides comprehensive support for the patient's lower leg and foot, ensuring a comfortable and stable posture during prolonged lying or rest, reducing pressure and discomfort caused by improper posture. The foot pad 40 is specifically designed to stabilize the patient's foot, effectively preventing foot drop and maintaining normal foot function and shape, which is especially important for patients who are bedridden for extended periods or in the recovery phase. The adjustable component 32 allows the angle of the foot pad 40 to be flexibly adjusted according to the patient's specific needs and comfort, enhancing the adaptability and personalized user experience of the device and meeting the needs of different patients. Meanwhile, the leg pad 20 is detachably installed in the first mounting slot 11 and fixed by the locking member 13. This design makes it easy for medical staff to quickly install or remove the leg pad 20 according to the patient's actual situation, improving the convenience and efficiency of operation and facilitating medical and nursing work.

[0049] In summary, this heel support device for preventing pressure injuries not only effectively avoids pressure on the heel, improving patient comfort and stability, but also prevents complications such as foot drop. Furthermore, it offers excellent adjustability, convenience, and practicality.

[0050] Preferably, in one embodiment of the present invention, the lower ends of the left and right sides of the palm pad 40 are provided with a first rotating part 41, and the end of the first rotating part 41 is rotatably connected to the groove wall of the third mounting groove 31.

[0051] In this way, the palm pad 40 can rotate at a certain angle within the third mounting groove 31 via the first rotating part 41, which allows the device to adapt more flexibly to the foot angles and postures of different patients, improving the comfort and adaptability of use.

[0052] Preferably, in one embodiment of the present invention, the adjusting component 32 includes an adjusting screw 321, a support plate 323, and an adjusting nut 325.

[0053] One end of the adjusting screw is provided with a sleeve 322, and the rear side of the upper surface of the palm pad 40 is provided with a fourth mounting groove 42. A rotating shaft 421 is provided laterally in the fourth mounting groove 42, and the sleeve 322 is sleeved on the rotating shaft 421.

[0054] The upper end of the rear surface of the baffle is provided with a fifth mounting groove 33, the support plate 323 is provided in the fifth mounting groove 33, and the support plate 323 is provided with a second rotating part 324 on both the left and right sides. The other end of the second rotating part 324 is rotatably connected to the groove wall of the fifth mounting groove 33, and the other end of the adjusting screw 321 passes through the support plate 323.

[0055] The adjusting nut 325 is connected to the other end of the adjusting screw 321 and is threadedly connected to the adjusting screw 321. One side of the adjusting nut 325 is connected to the front side of the support plate 323 and is restricted to rotating only along its own axis.

[0056] Thus, by cooperating with the adjusting screw 321 and adjusting nut 325, the angle of the palm pad 40 can be precisely adjusted. Medical staff can easily adjust the position of the palm pad 40 according to the patient's specific needs and comfort, ensuring optimal support and fixation for the foot. The sleeve 322 is fitted onto the rotating shaft 421, and the support plate 323 is rotatably connected to the wall of the fifth mounting groove 33 via the second rotating part 324. These designs enhance the stability of the adjusting assembly 32. During adjustment, the components maintain a tight connection, ensuring that the palm pad 40 remains firmly in the desired position after adjustment. The design of the adjusting screw 321 and adjusting nut 325 makes the adjustment process simple and easy to understand, allowing medical staff to adjust the palm pad 40 without complicated operations.

[0057] Preferably, in one embodiment of the present invention, the front side of the support plate 323 is provided with a first annular protrusion 3231, the adjusting screw 321 passes through the first annular protrusion 3231, the outer surface of the first annular protrusion 3231 is provided with a connecting groove 3232, and the connecting groove 3232 extends circumferentially along the first annular protrusion 3231.

[0058] The rear side of the adjusting nut 325 is provided with a second annular protrusion 3251, and the inner wall of the second annular protrusion 3251 is provided with a connecting protrusion 3252. The connecting protrusion 3252 is rotatably sleeved in the connecting groove 3232.

[0059] Thus, the cooperation of the first annular protrusion 3231 and the second annular protrusion 3251, as well as the nested design of the connecting groove 3232 and the connecting protrusion 3252, ensures the stable connection of the adjusting nut 325 on the adjusting screw 321. This structure effectively prevents the adjusting nut 325 from axial displacement or falling off during adjustment, ensuring the accuracy and reliability of the adjustment. The design of the first annular protrusion 3231 and the second annular protrusion 3251 not only serves a connecting function but also enhances the structural strength between the support plate 323 and the adjusting nut 325. This design allows the adjusting assembly 32 to maintain stable performance even when subjected to large pressures or torques.

[0060] Preferably, in one embodiment of the present invention, the locking member 13 includes a locking piece 131, a plurality of elastic members 132 and a driving piece 133.

[0061] The front end face of the tray 10 is provided with a sixth mounting groove 14. The locking piece 131 is horizontally disposed in the sixth mounting groove 14 and can move in the vertical direction. The top surface of the sixth mounting groove 14 is provided with a through groove 15 that extends into the first mounting groove 11. The upper end of the locking piece 131 extends through the through groove 15 into the first mounting groove 11.

[0062] Multiple elastic elements 132 are disposed on the bottom surface of the locking piece 131 and are distributed at intervals along the length direction of the locking piece 131. The lower ends of the multiple elastic elements 132 are connected to the bottom surface of the sixth mounting groove 14.

[0063] The drive plate 133 is connected to the side of the locking plate 131, and one end extends toward the front end face of the support plate 10 to drive the locking plate 131 to move up and down.

[0064] The leg pad 20 has a slot 2121 at the front end of its bottom surface, and the upper end of the locking piece 131 is inserted into the slot 2121.

[0065] Thus, the locking piece 131, by inserting its upper end into the slot 2121 at the front end of the bottom of the leg pad 20 on the support plate 10, reliably locks the leg pad 20. Multiple elastic elements 132 are disposed on the bottom surface of the locking piece 131 and spaced apart along its length. These elastic elements 132 provide an upward elastic force to the locking piece 131, allowing it to automatically reset after unlocking, facilitating subsequent use. The drive piece 133 is connected to the side of the locking piece 131, with one end extending towards the front end of the support plate 10. Medical personnel can easily raise and lower the locking piece 131 through simple manual operation, achieving rapid locking and unlocking of the leg pad 20. This design simplifies the operation process and improves work efficiency.

[0066] Preferably, in one embodiment of the present invention, the connection between the front side and the upper surface of the locking piece 131 is an arc-shaped transition surface 1311.

[0067] Thus, the design of the arc-shaped transition surface 1311 makes the edge contact of the leg pad 20 smoother during insertion, reducing friction and wear. This allows it to smoothly press the locking piece 131 downwards. Once the leg pad 20 is in place, the elastic force of the elastic element 132 causes it to spring back and insert into the slot 2121. Preferably, in one embodiment of the present invention, a pointer 34 is provided on both sides of the baffle, the pointer 34 is connected to the first rotating part 41 and rotates with the first rotating part 41; The pointer 34 is surrounded by multiple scale lines 341, which are arranged in an arc shape with the first rotating part 41 as the center. The end of the pointer 34 points to one of the scale lines 341.

[0068] Thus, the combination of pointer 34 and scale line 341 allows the rotation angle of the first rotating part 41 to be intuitively read through the scale line 341 pointed to by pointer 34. This provides the user with immediate feedback, facilitating accurate understanding and adjustment of the position or angle of the rotating part. Through the subdivision of the scale line 341, the user can more precisely control the rotation angle of the first rotating part 41.

[0069] Preferably, in one embodiment of the present invention, a flexible pad 43 is provided on the front side of the palm pad 40, and the flexible pad 43 and the palm pad 40 are detachably connected.

[0070] Thus, the material of the flexible pad 43 is usually softer and more skin-friendly, providing users with a more comfortable touch. The detachable connection design between the flexible pad 43 and the palm pad 40 makes it easy to remove the flexible pad 43 for cleaning or replacement.

[0071] Preferably, in one embodiment of the present invention, the front side of the palm pad 40 is provided with an elastic fixing band 44, the two ends of the elastic fixing band 44 are respectively connected to the left and right sides of the palm pad 40, so as to fix the patient's foot on the palm pad 40.

[0072] In this way, the elastic fixing band 44 can firmly fix the patient's foot on the palm pad 40, effectively preventing the foot from sliding or shifting during use, thereby enhancing the stability of the foot placement. The elastic fixing band 44 has a certain degree of elasticity and can adapt to different foot sizes.
