Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a limb burn treatment stent. Background Technology
[0002] Limb burn treatment braces are a type of medical assistive device designed for patients with burns to the limbs. They are mainly used in the burn treatment and rehabilitation stages, while also preventing complications such as joint contractures and scar hyperplasia. By fixing the limb in a functional position, they prevent patients from maintaining a contracted position due to pain, and prevent limb deformities caused by joint contractures and scar traction. Static fixation braces are suitable for the early stages of burns or situations with a high risk of joint contractures, by fixing the limb to restrict abnormal movements.
[0003] In existing technological applications, traditional static fixation braces for early-stage burns use multiple sets of Velcro to bind and fix the burned limb. However, because the braces rely on multiple sets of Velcro for dispersed binding, and the Velcro's placement lacks directional avoidance for the burn wound, some Velcro may directly contact the skin of the burned area. This poses a high risk of secondary damage to the burn wound. Furthermore, the Velcro's contact surface is often made of nylon with hooks and barbs, which may exert physical pressure on the damaged skin tissue, exacerbating local damage. It may also interfere with the normal drainage of wound exudate, increasing the risk of infection. Utility Model Content
[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a limb burn treatment stent, which can effectively solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a limb burn treatment support, including an arc-shaped frame, Velcro straps and Velcro tapes. The inner side wall of the arc-shaped frame is fixedly equipped with a soft pad, and the two side walls of the arc-shaped frame are fixedly equipped with two guide rods. Each of the two guide rods is provided with an adjustment and fixing component on one side. The adjustment and fixing assembly includes a connecting block, one end of which is fixedly mounted with an mounting plate, and the top surface of the mounting plate is fixedly mounted on the bottom of the Velcro tape and the Velcro tape respectively.
[0006] Furthermore, a sleeve is fixedly fitted inside the connecting block, and the inside of the sleeve is a hollow structure. A closed cover structure is fixedly installed on one side of the sleeve, and a movable piece is slidably fitted inside the sleeve.
[0007] Furthermore, a compression spring is fixedly installed at one end of the movable piece, and the other end of the compression spring is fixedly installed at one end of the inner wall of the sleeve. A pull rod is fixedly sleeved inside the movable piece, and the pull rod is slidably sleeved inside the sleeve.
[0008] Furthermore, a locking block is fixedly installed at one end of the pull rod, and the locking block is located between the guide rod and the connecting block.
[0009] Furthermore, a sliding groove is provided through the interior of the two guide rods, and a sliding block is slidably fitted inside the sliding groove. One side of the sliding block is connected to one side of the mounting plate. A limit block is fixedly fitted to one end of the guide rod, and limit holes are provided on one side of both guide rods at equal intervals.
[0010] Furthermore, one side of the limiting hole is aligned with the card block, and the card block is inserted inside the limiting hole to limit the card block.
[0011] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model allows operators to adjust the fixing component by pulling the lever of the fixing component to release the position lock, causing the sliding block to move within the sliding groove of the guide rod. This, in turn, moves and adjusts the mounting plate, Velcro tape, and Velcro tape to a suitable position that avoids the burn area of the lower limbs. This prevents some Velcro tape and Velcro tape from contacting the burned skin of the lower limbs, thus avoiding the high risk of secondary damage to the burn wound. It also prevents physical pressure on the damaged skin tissue, which could aggravate local damage and increase the risk of infection.
[0012] 2. Through the use of soft pads and limiting blocks, the soft pads can buffer the local pressure of the arc frame on the limbs and reduce the discomfort of pressure on non-burn areas, while the limiting blocks can prevent components such as sliding blocks, mounting plates, Velcro straps and Velcro straps from detaching from the outside of the guide rod.

Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0017] The present invention will be further described below with reference to the embodiments.
[0018] Example 1: Reference Figures 1 to 4 This is the first embodiment of the present invention, which discloses a limb burn treatment support, including an arc frame 1, a Velcro strap 5 and a Velcro strap 6. A soft pad 3 is fixedly installed on the inner side wall of the arc frame 1. The soft pad 3 fixed on the inner side wall is made of a flexible and breathable material, which can buffer the local pressure of the arc frame 1 on the limb and reduce the discomfort of pressure on non-burn areas. Here, the arc frame 1 is made of flexible plastic material and is suitable for the lower limb (leg). Two guide rods 2 are fixedly installed on the two side walls of the arc frame 1. The two guide rods 2 are connected by heat fusion. An adjustment and fixing component 4 is provided on one side of each of the two guide rods 2. The adjusting and fixing component 4 includes a connecting block 43. One end of the connecting block 43 is fixedly fitted with a mounting plate 42. The top surface of the mounting plate 42 is fixedly mounted on the bottom of the hook and loop tape 5 and the hook and loop tape 6, respectively. The hook and loop tape 5 and the hook and loop tape 6 act as flexible fixing components. Through their adhesive bonding, the limb can be stably restrained within the support space formed by the arc-shaped frame 1 and the soft pad 3. The top surface of the mounting plate 42 serves as the mounting base for the hook and loop tape 5 and the hook and loop tape 6. They are fixed to the hook and loop tape 5 and the hook and loop tape 6 respectively by strong adhesive bonding, riveting, or sewing. The bottom of the connector and the bottom of the Velcro 6 are firmly connected. A sleeve 44 is fixedly sleeved inside the connector block 43. The sleeve 44 has a hollow structure inside. A closed cover structure is fixedly installed on one side of the sleeve 44. A movable piece 46 is slidably sleeved inside the sleeve 44. Inside the sleeve 44, a movable piece 46 is slidably sleeved and fits tightly against the inner wall of the sleeve 44. The outer diameter of the movable piece 46 is clearance-fitted with the inner diameter of the sleeve 44. The clearance is controlled within a very small range to ensure that the movable piece 46 can slide smoothly along the axis inside the sleeve 44.
[0019] One end of the movable piece 46 is fixedly equipped with a compression spring 47, and the other end of the compression spring 47 is fixedly equipped with one end of the inner wall of the sleeve 44. A pull rod 45 is fixedly sleeved inside the movable piece 46 and slides inside the sleeve 44. One end of the pull rod 45 is fixedly equipped with a locking block 48, which is located between the guide rod 2 and the connecting block 43. The operator holds the end of the pull rod 45 away from the locking block 48 and applies a pulling force away from the guide rod 2. The pulling force is transmitted to the movable piece 46 through the pull rod 45, causing the movable piece 46 to slide inside the sleeve 44 away from the guide rod 2. At the same time, the compression spring 47 inside the sleeve 44 is compressed. As the movable piece 46 slides, the pull rod 45 moves synchronously, and the locking block 48 at its end gradually disengages from the currently inserted limiting hole 22 until the locking block 48 is completely disengaged from the limiting hole 22.
[0020] Reference Figures 2 to 4The two guide rods 2 have sliding grooves 21 extending through their interiors. Sliding blocks 41 are slidably fitted inside the sliding grooves 21. When adjusting the positions of the hook and loop tapes 5 and 6, moving them away from the burn area of the lower limb, the sliding blocks 41 move within the sliding grooves 21 of the two guide rods 2. One side of the sliding block 41 connects to one side of the mounting plate 42, further moving the mounting plate 42, thereby moving and adjusting the hook and loop tapes 5 and 6. One end of the guide rod 2 is fixed... The fixed sleeve has a limiting block 7, which prevents the mounting piece 42, hook and loop tape 5, and hook and loop tape 6 from falling off the outside of the guide rod 2. The two guide rods 2 have limiting holes 22 arranged at equal intervals on one side. One side of the limiting hole 22 is aligned with the locking block 48. The compression spring 47 pushes the locking block 48 into the limiting hole 22, locking the sliding block 41, mounting piece 42, hook and loop tape 5, and hook and loop tape 6. The locking block 48 is inserted into the limiting hole 22, which limits the locking block 48.
[0021] The workflow of this utility model is as follows: First, assist the patient to slowly place the burned leg inside the curved frame 1, ensuring that the burned wound faces outward or upward, completely avoiding the curved frame 1 and the soft pad 3, and not contacting any support components. At this time, the soft pad 3 should fully conform to the non-burned area of the leg to form a uniform cushioning support.
[0022] Secondly, based on the location of the burn on the patient's lower limb leg, the operator holds the pull rod 45 of the adjusting and fixing component 4 and pulls it away from the guide rod 2. This causes the pull rod 45 to drive the movable piece 46 to compress the spring 47, and the locking block 48 to disengage from the current limiting hole 22, releasing the position lock. As a result, the sliding block 41 moves inside the sliding groove 21 of the two guide rods 2. One side of the sliding block 41 connects to one side of the mounting piece 42, further driving the mounting piece 42 to move. This, in turn, drives the Velcro strap 5 and Velcro strap 6 to move and adjust, adjusting the two sets of adjusting and fixing components 4 to avoid the burn area. When the appropriate position is reached, the lever 45 is released, the compressed spring 47 returns to its original position, and the movable piece 46 is pushed, causing the locking block 48 to insert into the corresponding limiting hole 22. This completes the locking of the position of the adjustment and fixing component 4, ensuring that the Velcro tape 5 and Velcro tape 6 avoid the burn area of the lower limb leg and are wrapped and fixed. The Velcro tape 5 and Velcro tape 6 avoid contact with the burn skin of the lower limb, thus avoiding the high risk of secondary damage to the burn wound. This also prevents physical pressure on the damaged skin tissue, which could aggravate local damage and increase the risk of infection.
[0023] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
