Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, specifically, it relates to an elastic stocking for lower limb lymphedema. Background Technology

[0002] Lymphedema is a localized edema caused by impaired lymphatic drainage. Due to various reasons, lymph can accumulate in the subcutaneous tissue, leading to fibrosis, fat hardening, and eventually limb swelling, thickened and rough skin.

[0003] A search revealed that CN220424073U discloses an elastic stocking specifically for lower limb lymphedema. The waist stocking has an opening at the lower body to prevent pressure on the perineum and thus avoid edema. The leg stocking has an opening at the side of the leg. The opening of the leg stocking is connected by an elastic adjustment unit. It is easy to wear, the wearing pressure is adjustable, and it is comfortable.

[0004] These elastic stockings are made by bonding nylon hooks and loops to nylon fleece tape and then wrapping the leg opening around the patient's leg. Because of the high elasticity of the stockings, the tensile force is also high. If the bonding is not in place, the stockings may break, which will greatly affect the user experience. Therefore, the bonding method is not very secure.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To address the problem that the current elastic stockings are secured by bonding nylon hooks and loops to nylon fleece tape and then wrapping the leg opening around the patient's leg, this method of bonding, due to the high elasticity of the stockings and the resulting tensile force, can easily break if not properly bonded, significantly impacting the user experience. Therefore, the basic concept of this invention is as follows:

[0007] An elastic stocking specifically designed for lower limb lymphedema, including a waist stocking;

[0008] A connecting strap is attached to the inside of the waist stocking. A connecting mechanism is provided below the connecting strap, and an adjustment mechanism is provided on one side of the connecting mechanism. The connecting mechanism includes a leg stocking attached below the connecting strap.

[0009] A fixing strip is connected to one side of the outer wall of the leg stocking. The outer wall of the fixing strip has a groove. The bottom of the inner wall of the groove has a sliding hole. The bottom of the inner wall of the sliding hole is connected to a first spring. The end of the first spring away from the inner wall of the sliding hole is connected to a connecting slide rod. The top of the connecting slide rod is connected to a stabilizing slide rod. The top of the inner wall of the groove has a sliding groove. The outer wall of the stabilizing slide rod is slidably disposed on the inner wall of the sliding groove. A connecting plate is connected to the outer wall of the connecting slide rod. A positioning rod is connected to the bottom of the connecting plate. The end of the connecting slide rod away from the stabilizing slide rod is connected to a connecting post. A locking block is provided on the outer wall of the other side of the leg stocking. The top of the locking block has a locking hole.

[0010] In a preferred embodiment of this utility model, the adjustment mechanism includes a connecting piece connected to the outer wall of the sock on the other side. A limiting groove is formed on the outer wall of the connecting piece. A limiting slider is slidably provided on the inner wall of the limiting groove. One side of the outer wall of the limiting slider is connected to the outer wall of the locking block. A support block is connected to one side of the outer wall of the locking block. A circular hole is formed on the outer wall of the support block. A second spring is connected to the inner wall of the circular hole. A pull rod is connected to the end of the second spring away from the inner wall of the circular hole. A positioning post is connected to the outer wall of one end of the pull rod. The outer wall of the positioning post movably passes through the inner wall of the circular hole. A positioning hole is formed on the inner wall of the limiting groove.

[0011] In a preferred embodiment of this utility model, there are two slots and two positioning rods, and the slots and positioning rods are symmetrically distributed on the fixing strip.

[0012] In a preferred embodiment of this utility model, the outer wall of the card block is fitted with the inner wall of the card slot, and the outer wall of the positioning rod is fitted with the inner wall of the card hole.

[0013] In a preferred embodiment of this utility model, the bottom and top ends of the inner walls on both sides of the card slot are provided with connecting holes, and the outer wall of the connecting column is movably disposed on the inner wall of the connecting hole.

[0014] In a preferred embodiment of this utility model, the number of positioning holes is several, and the positioning holes are evenly and equidistantly distributed on the inner wall of the limiting slide groove. Both the connecting piece and the limiting slider are made of soft material.

[0015] In a preferred embodiment of this utility model, the inner wall of the positioning hole is fitted with the outer wall of the positioning post, and the inner wall of the limiting groove is fitted with the outer wall of the limiting slider.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] This invention utilizes a method where pulling one side of the leg stocking moves the fixing strip to the position of the fixing block. Then, moving the connecting slide rod upwards moves the positioning rod upwards, simultaneously moving the connecting column upwards, which in turn moves the bottom positioning rod upwards. The fixing block then engages with the inner wall of the slot. Releasing the connecting slide rod allows the return of the first spring to push the upper and lower positioning rods back into place, engaging with the inner wall of the positioning hole, thus completing the connection between the two leg stockings. This connection method is relatively stable and will not cause the stockings to come undone due to elasticity, ensuring a comfortable wearing experience for the patient.

[0018] This invention utilizes a pull rod to move a positioning pin, disengaging it from the inner wall of the current locking hole. The support block can then be moved left and right, causing the fixing block to move as well. During this movement, a limiting slider moves within the limiting groove, providing effective and stable support. Once the pin is in the correct position, the pull rod can be released, and the return of the second spring resets the positioning pin, causing it to engage with the inner wall of the current locking hole, thus completing the positioning. This allows the design to accommodate different leg sizes, improving the applicability of the elastic stockings.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] like Figures 1 to 5 As shown, a type of elastic stocking for lower limb lymphedema includes a waist stocking 1, a connecting strap 2 connected to the inside of the waist stocking 1, a connecting mechanism 31 below the connecting strap 2, and an adjustment mechanism 32 on one side of the connecting mechanism 31. The connecting mechanism 31 includes a leg stocking 3111 connected below the connecting strap 2. A fixing strip 311 is connected to the outer wall of one side of the leg stocking 3111. A groove 312 is formed on the outer wall of the fixing strip 311. A sliding hole is formed at the bottom end of the inner wall of the groove 312. A first spring 313 is connected to the bottom end of the inner wall of the sliding hole. The first spring 313 is located at... A connecting slide rod 314 is connected to one end of the inner wall of the sliding hole. A stabilizing slide rod 315 is connected to the top of the connecting slide rod 314. A groove is opened at the top of the inner wall of the slot 312. The outer wall of the stabilizing slide rod 315 is slidably disposed on the inner wall of the groove. A connecting plate 316 is connected to the outer wall of the connecting slide rod 314. A positioning rod 317 is connected to the bottom of the connecting plate 316. A connecting post 318 is connected to the end of the connecting slide rod 314 away from the stabilizing slide rod 315. A locking block 319 is provided on the outer wall of the other side of the leg stocking 3111. A locking hole 3110 is opened at the top of the locking block 319.

[0029] Furthermore, there are two slots 312 and two positioning rods 317. The slots 312 and the positioning rods 317 are symmetrically distributed on the fixing strip 311, so that the upper and lower sides of the leg stocking 3111 can be connected synchronously and evenly to ensure uniform force distribution.

[0030] Furthermore, the outer wall of the locking block 319 fits snugly against the inner wall of the slot 312, and the outer wall of the positioning rod 317 fits snugly against the inner wall of the locking hole 3110, thus ensuring the stability of the locking block 319 after it is engaged with the inner wall of the slot 312.

[0031] Furthermore, the bottom and top ends of the inner walls on both sides of the slot 312 are provided with connecting holes, and the outer wall of the connecting post 318 is movably disposed on the inner wall of the connecting hole. The connecting hole provides space for the connecting post 318 to move, thereby driving the positioning rods 317 on both sides to move in one step.

[0032] The adjustment mechanism 32 includes a connecting piece 321 connected to the outer wall of the leg stocking 3111 on the other side. A limiting groove 322 is formed on the outer wall of the connecting piece 321. A limiting slider 323 is slidably provided on the inner wall of the limiting groove 322. One side of the outer wall of the limiting slider 323 is connected to the outer wall of the locking block 319. A support block 324 is connected to one side of the outer wall of the locking block 319. A circular hole is formed on the outer wall of the support block 324. A second spring 325 is connected to the inner wall of the circular hole. A pull rod 326 is connected to the end of the second spring 325 away from the inner wall of the circular hole. A positioning post 327 is connected to the outer wall of one end of the pull rod 326. The outer wall of the positioning post 327 moves through the inner wall of the circular hole. A positioning hole 328 is formed on the inner wall of the limiting groove 322.

[0033] Furthermore, there are several positioning holes 328, which are evenly and equidistantly distributed on the inner wall of the limiting slide groove 322. The connecting piece 321 and the limiting slider 323 are both made of soft material, so that multiple adjustments can be made according to the multiple positioning holes 328 to adapt to different patients.

[0034] Furthermore, the inner wall of the positioning hole 328 fits snugly against the outer wall of the positioning post 327, and the inner wall of the limiting groove 322 fits snugly against the outer wall of the limiting slider 323. This ensures the stability of the positioning post 327 after it is engaged with the inner wall of the positioning hole 328.

[0035] The implementation principle of the elastic stockings for lower limb lymphedema in this embodiment is as follows: In use, first, the waist stocking 1 is put on. Then, the position of the locking block 319 is adjusted according to the patient's leg size. Next, the leg stocking 3111 on the other side is pulled, causing the leg stocking 3111 to move along the fixing strip 311, so that this leg stocking 3111 wraps around the leg stocking 3111 on the side with the locking block 319. Simultaneously, the connecting slide rod 314 is pushed upwards, causing the connecting plate 316 and positioning rod 317 connected to its outer wall to move upwards. During the movement of the connecting slide rod 314, the first spring 313 is stretched. At this time, the positioning rod 317 will move away from the bottom of the inner wall of the locking groove 312. Simultaneously, while pulling the connecting slide rod 314, the connecting column 318 is also moved upwards. As the connecting column 318 moves, the bottom... The connecting slide bar 314 moves upward, which in turn moves the bottom positioning bar 317 upward away from the bottom of the inner wall of the slot 312. After the fixing bar 311 is moved to the position of the locking block 319, the fixing bar 311 can be pulled according to the position of the locking block 319, so that the slot 312 on the fixing bar 311 moves to the position of the locking block 319. Then the locking block 319 can be locked into the inner wall of the slot 312. After locking, the connecting slide bar 314 can be released, and the rebound of the first spring 313 can drive the connecting slide bar 314 to reset, thereby driving the positioning bars 317 on both sides to reset, so that the outer wall of the positioning bar 317 is locked into the inner wall of the locking hole 3110, thus completing the connection of the two leg stockings 3111. This connection method is more stable and will not cause the leg stockings 3111 to come apart due to the elasticity of the leg stockings 3111, ensuring the patient's experience during wearing.

[0036] When adjusting the position of the locking block 319, first pull the lever 326 outward to move the positioning post 327 outward. During the movement, the second spring 325 will be stretched, causing the outer wall of the positioning post 327 to disengage from the inner wall of the currently engaged positioning hole 328. At this point, the limiting of the support block 324 and the locking block 319 can be released. Then, move the support block 324 and the locking block 319, which will cause the limiting slider 323 to move within the inner wall of the limiting groove 322. This completes the position adjustment of the locking block 319, thus adapting to different patients' leg sizes. After moving to the appropriate position, release the lever 326. The rebound of the second spring 325 will reset the positioning post 327, causing the outer wall of the positioning post 327 to engage with the inner wall of the currently engaged positioning hole 328, completing the positioning.
