Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure ulcer prevention and hand care technology, specifically to a pressure ulcer prevention and hand care device. Background Technology
[0002] Pressure ulcers, also known as bedsores or pressure sores, are a condition caused by prolonged, sustained pressure that damages the skin or subcutaneous tissue. This pressure is often caused by prolonged periods of lying in bed or a wheelchair. Pressure ulcers most commonly appear on the skin covering areas of the body that are close to the bones.
[0003] Existing pressure ulcer prevention hand care devices involve placing the bedridden patient's hand on a sponge pad or other soft material to reduce pressure on the hand. This method of protection is too rudimentary and ineffective. Therefore, we propose a pressure ulcer prevention hand care device. Utility Model Content
[0004] The purpose of this invention is to provide a hand care device to prevent pressure sores, so as to solve the problem that the protection methods mentioned in the background art are too simple and have poor protective effects.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a pressure ulcer prevention hand care device, comprising: a mounting plate, a breathable glove on the top of the mounting plate, two observation ports on the top of the breathable glove, an air cushion fixedly connected inside the breathable glove, a connecting tube fixedly connected to the outside of the breathable glove, an air bag fixedly connected to the end of the connecting tube away from the breathable glove, multiple slots on the top of the mounting plate, and a pushing mechanism on the outside of the mounting plate.
[0006] The driving mechanism includes a controller and a motor. The controller is fixedly connected to the outside of the mounting plate. A button is fixedly connected to the outside of the controller. A charging port is provided on the top of the controller. The motor is fixedly connected to the outside of the mounting plate. A threaded rod is fixedly connected to the output end of the motor. A threaded sleeve is threadedly connected to the outer circumference of the threaded rod. A rotating rod is rotatably connected inside the threaded sleeve. Multiple protrusions are fixedly connected to the outer circumference of the rotating rod. A gear is fixedly connected to the end of the rotating rod away from the threaded sleeve. A sliding groove is opened inside the mounting plate. A rack is fixedly connected inside the mounting plate.
[0007] The end of the connecting tube furthest from the airbag is fixedly connected to the outside of the air cushion.
[0008] The outer side of the threaded sleeve is slidably connected to the inside of the mounting plate, and both ends of the threaded rod are rotatably connected to the inside of the mounting plate.
[0009] The gear is located on top of the rack, and the gear and the rack mesh together.
[0010] The end of the rotating rod away from the threaded sleeve is slidably connected inside the groove.
[0011] The protrusions are staggered around the outer periphery of the rotating rod, and are located directly below the groove.
[0012] This utility model has at least the following beneficial effects:
[0013] In use, this utility model, through the setting of a pushing mechanism, enables massage and pushing of the hand when the patient is in bed, helping the patient to perform hand movements. This prevents the patient from being in bed for a long time, with the hand remaining still for a long time, resulting in continuous pressure on the hand and poor blood circulation, which could lead to damage to the skin or subcutaneous tissue. This improves the protective effect and increases the practicality of the device. Attached Figure Description

[0021] 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.
[0022] Example 1
[0023] Please see Figures 1 to 6This utility model provides a technical solution: a pressure ulcer prevention hand care device, comprising: a mounting plate 1, a breathable glove 2 on the top of the mounting plate 1, two observation ports 3 on the top of the breathable glove 2, an air cushion 4 fixedly connected inside the breathable glove 2, a connecting tube 5 fixedly connected to the outside of the breathable glove 2, an air bag 6 fixedly connected to the end of the connecting tube 5 away from the breathable glove 2, multiple slots 7 on the top of the mounting plate 1, and a pushing mechanism 8 on the outside of the mounting plate 1. In use, the device is placed on the bed, the glove is attached to the mounting plate 1 with Velcro, the patient's hand is put into the glove, and the air cushion 4 is inflated through the air bag 6 and the connecting tube 5 to support the patient's hand and prevent the patient's hand from being placed on a hard bed board. The color of the patient's hand can be observed through the observation slots to judge the pressure condition. The pushing mechanism 8 can massage the patient's hand, assist hand movement, and promote blood circulation in the hand. After use, the glove can be removed for disinfection and cleaning.
[0024] The driving mechanism 8 includes a controller 80 and a motor 83. The controller 80 is fixedly connected to the outside of the mounting plate 1. A button 81 is fixedly connected to the outside of the controller 80. A charging port 82 is provided on the top of the controller 80. The motor 83 is fixedly connected to the outside of the mounting plate 1. A threaded rod 84 is fixedly connected to the output end of the motor 83. A threaded sleeve 85 is threadedly connected to the outer circumference of the threaded rod 84. A rotating rod 86 is rotatably connected inside the threaded sleeve 85. Multiple protrusions 87 are fixedly connected to the outer circumference of the rotating rod 86. A gear 88 is fixedly connected to the end of the rotating rod 86 away from the threaded sleeve 85. A sliding groove 89 is opened inside the mounting plate 1. A rack 810 is fixedly connected inside the mounting plate 1. In use, pressing the button 81 activates the controller 80, which provides power to the motor 83. Upon startup, motor 83 drives threaded rod 84 to rotate, which in turn drives threaded sleeve 85 to move inside mounting plate 1. As threaded sleeve 85 moves, it drives rotating rod 86 to move inside slide groove 89. Rotating rod 86 drives gear 88 to move, and gear 88 meshes with rack 810, causing gear 88 to rotate. Gear 88 then drives rotating rod 86 to rotate, which in turn drives protrusion 87 to rotate. Protrusion 87 extends sequentially from inside slot 7 and contacts the glove, providing a pushing massage to the patient's hand. When rotating rod 86 reaches the end of slide groove 89, controller 80 reverses the rotation of threaded rod 84, causing threaded sleeve 85 to drive rotating rod 86 in the opposite direction. This provides a back-and-forth massage to the hand, promoting blood circulation and preventing damage to the skin or subcutaneous tissue caused by continuous pressure on the hand.
[0025] Example 2
[0026] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the end of the connecting tube 5 away from the airbag 6 is fixedly connected to the outside of the air cushion 4, so that the airbag 6 can inflate the air cushion 4. The outer side of the threaded sleeve 85 is slidably connected to the inside of the mounting plate 1, so that the threaded sleeve 85 can move stably and does not rotate with the threaded rod 84. Both ends of the threaded rod 84 are rotatably connected to the inside of the mounting plate 1, so that the threaded rod 84 can rotate stably. The gear 88 is located at the top of the rack 810, and the gear 88 and the rack 810 mesh with each other, so that the gear 88 meshes with the rack 810 and rotates when it moves, thereby driving the rotating rod 86 to rotate. The end of the rotating rod 86 away from the threaded sleeve 85 is slidably connected to the inside of the slide groove 89, so that the rotating rod 86 can move stably. The protrusions 87 are staggered around the outer periphery of the rotating rod 86. The protrusions 87 are located directly below the groove 7, so that the protrusions 87 can extend out from the inside of the groove 7 in sequence to push and massage the patient's hand.
