Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable finger web pressure finger separator. Background Technology

[0002] Hand burns are a common type of trauma, with complex and varied sequelae that severely impact patients' quality of life and functional recovery. Common manifestations of hand burns include: local wound inflammation, swelling, itching and pigmentation changes at the skin graft and donor sites, joint stiffness, extension contractures of the metacarpophalangeal joints, flexion contractures of the proximal interphalangeal joints, webbed fingers, especially thumb webbed fingers, hypertrophic scars, nail bed damage, and severe psychological trauma.

[0003] The rehabilitation goals for hand burns are to reduce swelling, maintain or restore joint range of motion, reduce contractures and deformities, and ultimately rebuild maximum hand function to help patients reintegrate into their families and society. Braces play a crucial role in both the acute and rehabilitation phases of hand burns, effectively preventing or correcting hand deformities, particularly in early prevention of webbed fingers or adhesions, and later in correcting webbed scarring or contractures.

[0004] Existing orthoses, when addressing finger web contracture, typically provide relatively fixed pressure. Over time, as the body's sensitivity and tolerance increase, the pressure from these orthoses gradually decreases, failing to provide sustained effective support. Users cannot adjust the pressure according to their needs. This leads to a gradual weakening of the orthosis's effectiveness during rehabilitation, sometimes necessitating frequent replacements, increasing the patient's financial burden and inconvenience. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the technical problem of this utility model is to provide an adjustable finger web pressure finger separator.

[0006] An adjustable finger web pressure finger plate includes a thermoplastic plate, elastic bands, elastic steel wires, elastic rubber bands, guide blocks, threaded rods, fastening nuts, and positioning sliders. The thermoplastic plate is designed in an ergonomic hand shape, covering the fingers, finger webs, palm, and wrist. Two elastic bands are connected to the wrist position on the bottom surface of the thermoplastic plate, and there are four elastic bands for the finger webs. Guide blocks are connected to the top surface of the thermoplastic plate near each finger web, and threaded rods are slidably inserted into each guide block. Positioning sliders are threadedly connected to the bottom of each threaded rod, and the positioning sliders are slidably connected to the inside of the thermoplastic plate. Elastic steel wires are connected to the palm position on the bottom surface of the thermoplastic plate, and four elastic rubber bands are connected to the elastic steel wires at intervals. One end of each elastic rubber band goes upward around the corresponding finger web position and then fits onto the threaded rod. Fastening nuts are threadedly connected to the top of each threaded rod, and the fastening nuts lock the elastic rubber bands.

[0007] Optionally, it also includes silicone grease filling, with silicone grease filling attached to the elastic bands at the web positions.

[0008] Optionally, it also includes a recess and a protrusion, with a recess on the bottom surface of the guide block and a protrusion on the top of the positioning slider, the two engaging with each other.

[0009] Optionally, it also includes a knuckle fixation strap and a fixation ring. The knuckle fixation strap is threaded through the fingers on the thermoplastic plate. The two ends of the knuckle fixation strap are located above the thermoplastic plate, and the two ends of the knuckle fixation strap are connected by a fixation ring, forming a ring.

[0010] Optionally, it also includes a Velcro strap, which is attached to the wrist portion of the thermoplastic plate near the palm.

[0011] Optionally, it also includes massage balls, with several ventilation holes spaced apart on the thermoplastic plate, and multiple massage balls connected at intervals on the bottom surface of the thermoplastic plate.

[0012] The beneficial effects are as follows: 1. One end of the elastic band is attached to the threaded rod, and the threaded rod can slide and adjust on the guide block, thereby adjusting the pressure of the elastic band. In the early postoperative period, the fingers and finger webs are relatively fragile and require greater support to maintain the correct position of the fingers, prevent adhesion and joint contracture. By increasing the pressure of the elastic band, sufficient support can be provided to help the fingers maintain the separated state and promote healing.

[0013] 2. As the rehabilitation process progresses, users can gradually reduce the pressure on the elastic band in the middle stage, allowing more finger movement and flexibility to promote functional recovery. In the later stage of rehabilitation, only slight pressure is needed to maintain the correct finger posture and ensure the natural range of motion of the fingers.

[0014] 3. The adjustable design of the elastic band allows users to make precise adjustments according to their hand shape, strength level, and comfort, ensuring that each user can obtain the most suitable treatment effect. For example, users with thinner or thicker fingers can find the most comfortable way to wear it by adjusting the tension of the elastic band, avoiding discomfort or ineffective treatment caused by being too tight or too loose.

Detailed Implementation

[0023] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example: An adjustable finger web pressure finger separator, such as Figures 1-6As shown, the device includes a thermoplastic plate 1, elastic bands 4, elastic steel wires 6, elastic rubber bands 7, silicone grease filling 8, guide blocks 9, threaded rods 10, fastening nuts 11, positioning sliders 12, recesses 13, and protrusions 131. The thermoplastic plate 1 is designed in an ergonomic hand shape, covering the fingers, webs, palm, and wrist to form a complete support structure. Two elastic bands 4 are connected to the wrist position on the bottom surface of the thermoplastic plate 1 to ensure a tight fit between the device and the user's hand, preventing slippage or detachment. There are four webs. Guide blocks 9 are connected to the top surface of the thermoplastic plate 1 near each web. Threaded rods 10 are slidably inserted into each guide block 9. Square positioning sliders 12 are threaded to the bottom of each threaded rod 10. The positioning sliders 12 are slidably connected to the inside of the thermoplastic plate 1 and are limited by the thermoplastic plate 1 to prevent rotation. The bottom surface of the guide block 9 has a recess. 13. The top of the positioning slider 12 is provided with a protrusion 131, which engages with each other to ensure that the positioning slider 12 can be firmly fixed after adjustment and prevent slippage. An elastic steel wire 6 is connected to the palm position on the bottom surface of the thermoplastic plate 1. Four elastic rubber bands 7 are connected to the elastic steel wire 6 at intervals. One end of each elastic rubber band 7 is wrapped upwards around the corresponding finger web position and then sleeved on the threaded rod 10. The top of the threaded rod 10 is threaded with a fastening nut 11, which locks the elastic rubber band 7 to ensure that one end of the elastic rubber band 7 is tightly fixed on the threaded rod 10. When disassembling, maintaining or replacing, the fastening nut 11 can be removed to loosen one end of the elastic rubber band 7. Silicone grease 8 is connected to the elastic rubber band 7 at the finger web position, which increases the pressure in the finger web area and enhances the support force of the elastic rubber band 7, ensuring that it has sufficient stability and elasticity.

[0025] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes a knuckle fixing strap 14 and a fixing ring 15. The knuckle fixing strap 14 is inserted through the fingers on the thermoplastic plate 1. The two ends of the knuckle fixing strap 14 are located above the thermoplastic plate 1. The two ends of the knuckle fixing strap 14 are connected by the fixing ring 15. The fixing ring 15 fixes the knuckle fixing strap 14 by friction. The knuckle fixing strap 14 forms a ring, which facilitates the user's fingers to enter the knuckle fixing strap 14. By adjusting the position of the fixing ring 15, the circumference of the ring formed by the knuckle fixing strap 14 can be flexibly adjusted to adapt to users with different finger sizes.

[0026] like Figure 1 , Figure 5 and Figure 6As shown, it also includes a Velcro strap 5. The Velcro strap 5 is connected to the wrist portion of the bottom surface of the thermoplastic plate 1 near the palm. The Velcro strap 5 is provided with a Velcro structure. The Velcro female is connected to the end of the Velcro strap 5, and the Velcro female is connected to the other side of the Velcro strap 5 near the edge. The Velcro strap 5 tightens the wrist. By adjusting the tightness, and then fixing the Velcro strap 5 in place, the tightness of the device at the wrist can be adjusted to ensure a secure fit.

[0027] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes massage balls 3. Several ventilation holes 2 are spaced apart on the thermoplastic plate 1 to ensure breathability after wearing and avoid skin discomfort caused by prolonged wear. Multiple massage balls 3 are connected at intervals on the bottom surface of the thermoplastic plate 1. When wearing, the massage balls 3 are in contact with the user's palm to massage, promote blood circulation, and improve user comfort.

[0028] When wearing this device, the user inserts their hand into the elastic band 4, with their palm against the bottom surface of the thermoplastic plate 1 (the side with the massage balls 3), the back of their hand through the elastic wire 6, and their fingers into the knuckle fixing strap 14. Then, the user tightens the Velcro strap 5, securing it to the wrist to prevent slippage. Next, the user adjusts the circumference of the knuckle fixing strap 14 to ensure a snug fit. After wearing the device, the pressure of the elastic band 7 can be adjusted. By turning the threaded rod 10, the positioning slider 12 moves downwards, separating the recessed portion 13 of the guide block 9 from the protruding portion 131 of the positioning slider 12, allowing the threaded rod 10 and the positioning slider 12 to slide back and forth along the guide block 9. Pulling one end of the elastic band 7 adjusts its tension. This changes the pressure applied to the finger webs. After adjustment, reverse the threaded rod 10 to move the positioning slider 12 upward. The protrusion 131 re-engages with the recess 13, fixing the positioning slider 12 and ensuring that the tension of the elastic band 7 remains stable. After wearing this device, appropriate pressure on the finger webs can improve blood circulation in the finger web area, aiding recovery and keeping the fingers separated, helping to maintain correct finger posture and preventing abnormal bending or crossing. The silicone grease 8 enhances the support of the elastic band 7, ensuring its sufficient stability, while the massage balls 3 provide additional comfort and massage effect. To remove the device, loosen the magic tightening strap 5 and the knuckle fixing strap 14.
