Description

Technical Field

[0001] This utility model belongs to the field of auxiliary device technology, specifically relating to a dialysis limb protection device. Background Technology

[0002] Hemodialysis (HD), also known as blood dialysis, is a commonly used method of blood purification. It mainly refers to establishing extracorporeal circulation through a hemodialysis device, simultaneously injecting the patient's blood and dialysate into the dialyzer, and using the diffusion effect of the dialyzer's semi-permeable membrane to remove small molecule metabolic waste or harmful substances from the blood, including urea, xenon, creatinine, small molecule toxins, and water, thereby correcting the patient's water load, electrolyte imbalance, and acid-base imbalance. Clinically, it is often used to treat acute and chronic renal failure, as well as drug or poisoning.

[0003] Hemodialysis involves drawing blood out of the body through an arteriovenous fistula or a hemodialysis catheter. The drawn blood then passes through a hemodialysis machine containing a synthetic membrane to remove toxins before being returned to the body. This process aims to remove excess fluid and toxins from the body and correct electrolyte imbalances.

[0004] Regardless of the dialysis method, blood needs to be transported to the dialysis machine for purification through two tubes (venous delivery tube and arterial delivery tube). The purified blood is then returned to the body through the tubes. However, the tubes are usually connected to the body through dressings and medical tape. A dialysis session typically lasts about 4 hours. The adhesiveness of the medical tape and dressings is lost when the patient sweats, and there is no other way to fix the tubes except through the tape. When the patient moves vigorously, the tubes can be pulled, affecting the stability of the dialysis process. Utility Model Content

[0005] This utility model discloses a dialysis limb protection device, which aims to solve the technical problem in the prior art where the dialysis tubing is not fixed and protected, which may be pulled and affect the stability of dialysis.

[0006] To solve the aforementioned technical problems, the present invention adopts the following technical solution:

[0007] A dialysis limb protection device includes a protective sleeve that can be fitted onto the arm. The protective sleeve has an opening that mates with an arteriovenous fistula. A clamping device that mates with a tubing is provided inside the opening. The clamping device includes several sliding bands, each of which can be slidably provided with several clamping blocks. Each clamping block has a clamping hole that mates with an arterial or venous delivery tube.

[0008] By adopting this technical solution, the protective sleeve can protect and keep the patient's arm warm, which can improve the patient's comfort during dialysis.

[0009] Inside the opening of the protective sleeve, a clamping block is installed to fit the tubing. The clamping block can clamp and guide the arterial and venous delivery tubes, allowing them to be clamped and guided on the protective sleeve. This prevents the tubes from getting tangled, supports the tubes, prevents the tube diameter from being squeezed, and prevents the tubes from coming loose when pulled, thus protecting the tubing.

[0010] The opening extends through both ends of the protective sleeve. The sidewall of the opening is provided with a first sliding part that cooperates with the sliding band. The first sliding part includes a sliding groove provided on the sidewall of the opening. A sliding plate is provided in the sliding groove. One end of the sliding band is provided with a slider that cooperates with the sliding plate. The slider is provided with a first locking device that cooperates with the protective sleeve.

[0011] By adopting this technical solution, the design of the chute and slide plate allows the longitudinal position of the sliding band within the opening to be altered through the interaction between the slider and the chute, thus aligning with the position of the patient's arteriovenous fistula on their arm. This improves the clamping and guiding effect on the tube and enhances the practicality of the device. The slide plate improves the smoothness of the slider's movement, increasing user comfort, while the first locking device enhances the stability of the sliding band's fixation to the protective sleeve, thereby improving the overall stability of the device during use.

[0012] The first locking device includes an elastic protrusion on the slider, and the slide plate and the protective sleeve are provided with several positioning grooves that cooperate with the elastic protrusion.

[0013] After adopting this technical solution, the setting of positioning groove and elastic protrusion simplifies the fixing method of sliding band and protective sleeve. When the sliding band slides to the appropriate position, the elastic protrusion on the slider will extend from the positioning groove to complete the fixing of the sliding band and protective sleeve, which is more convenient in operation.

[0014] The clamping block includes a rotatably connected male clamp and a female clamp. The female clamp is slidably connected to the sliding belt. The female clamp is provided with a sliding hole that cooperates with the sliding belt. The female clamp is provided with a second locking device that cooperates with the sliding belt.

[0015] With this technical solution, the sliding hole and the second locking device make it easier for medical staff to adjust the lateral position of the clamping block on the sliding band according to the location of the arteriovenous fistula in the patient's arm, so as to cooperate with the tube and clamp the tube, thereby improving the clamping and guiding effect of the tube and increasing the practicality of the device in use.

[0016] The second locking device includes several insert rods disposed on the female clamp, and several insertion holes for the insert rods to engage on the sliding band.

[0017] By adopting this technical solution, the design of the insertion rod and insertion hole simplifies the connection between the clamping block and the sliding band, thereby improving the ease of use of this device.

[0018] Both the male and female clamps are provided with arc-shaped grooves, and the two arc-shaped grooves form the clamping holes. The male and female clamps are provided with a third locking device.

[0019] By adopting this technical solution, the male and female clamps are configured to be rotatably connected, which facilitates the installation of pipes in the clamping holes. At the same time, a third locking device is set on the male and female clamps, which improves the stability of the clamping block during clamping, thereby improving the stability of the device during use.

[0020] The third locking device includes a slot and a plate respectively disposed on the male and female clamps, and both the slot and the plate are elastic structures.

[0021] By adopting this technical solution, a slot and a plug plate are used, and the slot and plug plate are connected and locked by an elastic structure, which not only improves the convenience of connecting the male and female clips, but also makes it easy to disconnect the male and female clips.

[0022] The protective cover has a through hole that mates with the sliding band. The sliding band and the protective cover are connected by a connecting device. The connecting device includes a Velcro patch on the outer wall of the protective cover and a Velcro female patch that mates with the Velcro patch on the side of the sliding band closest to the skin.

[0023] With this technical solution, one side of the sliding belt is connected to the protective sleeve via a slider, and the other end passes through and is connected to the protective sleeve via Velcro and Velcro fastener. Medical staff can use this structure to connect the other end of the sliding belt to the protective sleeve. The ring structure formed by the sliding belt and the protective sleeve can be adjusted according to the thickness of the patient's arm, which improves the practicality of the device.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0025] (1) Setting up a protective sleeve can protect and keep the patient's arm warm, which can improve the patient's comfort during dialysis. Inside the opening of the protective sleeve, there is a clamping block that fits with the tubing. The clamping block can clamp and guide the arterial and venous delivery tubes, so that the arterial and venous delivery tubes can be clamped and guided on the protective sleeve, preventing the tubes from getting tangled. It can also support the tubes, prevent the tubes from being squeezed and affecting the tube diameter, and prevent the tubes from coming off the needle when pulled, thus affecting the dialysis process and protecting the tubes.

[0026] (2) The setting of the chute and the slide plate can change the longitudinal position of the sliding band in the opening through the cooperation between the slider and the chute, so as to match the position of the patient's arteriovenous fistula on the arm, thereby improving the clamping and guiding effect of the tube and the practicality of the device.

[0027] (3) The setting of the sliding hole and the second locking device makes it convenient for medical staff to adjust the lateral position of the clamping block on the sliding band according to the position of the arteriovenous fistula in the patient's arm, cooperate with the pipeline, and clamp the pipeline, thereby improving the clamping and guiding effect of the pipeline and increasing the practicality of the device in use.

[0028] (4) One side of the sliding belt is connected to the protective sleeve via a slider, and the other end passes through and is connected to the protective sleeve via Velcro and Velcro. Medical staff can use this structure to connect the other end of the sliding belt to the protective sleeve. The ring structure formed by the sliding belt and the protective sleeve can be adjusted according to the thickness of the patient's arm, which improves the practicality of the device.
