Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to an adjustable fixation device for fixing a dialysis catheter in the neck. Background Technology

[0002] Previous studies have shown that the average age of hemodialysis patients has reached 60 years and above, and the aging population and multiple diseases have increased the difficulty of managing vascular access.

[0003] International studies show that the incidence of catheter dysfunction can reach 14% in the early stages of catheterization, and the risk of catheter-related complications increases with the duration of insertion. Vascular access is the "lifeline" for hemodialysis patients and is of great significance to patient treatment and clinical outcomes.

[0004] Current methods for securing neck hemofiltration catheters primarily employ single-dimensional fixation, posing significant safety risks. Patients experience considerable neck movement, and the numerous skin folds on the neck cause the exposed catheter tip to rub against clothing and the head, making fixation difficult and insecure. Furthermore, sweating and washing the face or hair can easily cause the adhesive tape to loosen or become contaminated. This increases the workload for nurses and the medical costs of replacing fixation devices. Some patients are allergic to the adhesive tape's components, experiencing allergic reactions such as itching, redness, and rashes. Frequent removal of the medical adhesive increases the risk of iatrogenic skin injuries. Overly tight binding can cause pressure on the skin when the patient turns over and increase discomfort in the head.

[0005] Therefore, postoperative care for hemodialysis patients after internal jugular vein catheterization is an essential and crucial step. Effective assessment and proper maintenance of the dialysis catheter are critical factors in determining its lifespan, indwelling time, and the incidence of complications; and nursing staff play a decisive role in dialysis catheter maintenance.

[0006] The dialysis catheter in the neck of a hemodialysis patient needs to be fixed for a long time during treatment. As can be seen from the above, traditional fixation methods, such as adhesive tape or gauze, have the following problems:

[0007] 1. Adhesive tape is prone to falling off due to patient sweating or contact with water, leading to catheter displacement or slippage;

[0008] 2. Adhesive tape can easily cause skin allergic reactions and increase the risk of iatrogenic skin damage;

[0009] 3. If the fixation is not secure, the catheter may rub or be compressed when the patient moves their neck.

[0010] 4. Frequent changes of adhesive tape increase nursing workload and medical costs.

[0011] Therefore, existing technologies lack a fixation device that can both securely fix the catheter and adapt to different patients' neck circumferences, improving comfort. Thus, a new fixation device is urgently needed to solve these problems. Summary of the Invention

[0012] To address the aforementioned technical problems, the purpose of this utility model is to provide an adjustable neck dialysis catheter fixation device to solve the problems of catheter slippage, skin allergies, and poor comfort in traditional fixation methods.

[0013] The objective of this utility model is achieved through the following technical solution:

[0014] An adjustable neck dialysis catheter fixation device includes: a strap-shaped body with multiple Velcro tabs and a female tab on the strap-shaped body, including:

[0015] The outer left side of the strip body is provided with a first hook and loop fastener, and the inner right side is provided with a first hook and loop fastener mother fastener that matches the first hook and loop fastener.

[0016] Next to the first Velcro attachment on the left outer side of the strip body, there is also a second Velcro mother attachment and a second Velcro attachment.

[0017] The outer right side of the strip body has a 1 / 2 width hook and loop third sub-attachment, and the inner side has a 1 / 2 width hook and loop fifth female attachment, and a hook and loop third female attachment connected to the hook and loop third sub-attachment.

[0018] On the right outer side of the strip body, there is a fourth hook and loop fastener and a fourth hook and loop fastener 5cm away from the third hook and loop fastener and the third hook and loop fastener.

[0019] Furthermore, the strip body is a long strip made of two layers of pure cotton fabric, with a length of 50cm and a width of 5cm.

[0020] Furthermore, the first, second, third, and fourth sub-attaches of the hook and loop fastener are barbed anchoring layers; the first, second, third, fourth, and fifth female attachments of the hook and loop fastener are velvet layers.

[0021] Furthermore, a double fixation structure for the conduit is formed by the initial fixation of the third hook and loop fastener to the second hook and loop fastener, and by the subsequent fixation of the second hook and loop fastener to half of the second hook and loop fastener and half of the fifth hook and loop fastener.

[0022] Furthermore, the combination of the fourth sub-attachment and the fourth mother-attachment of the Velcro allows for adjustment of the tightness of the band body to accommodate different patients' neck circumferences.

[0023] Compared with the prior art, one or more embodiments of this utility model may have the following advantages:

[0024] 1) Securely fixed: The multi-layer Velcro design effectively prevents the catheter from slipping or shifting;

[0025] 2) Adjustable design: adapts to different patients' neck circumferences, improving comfort;

[0026] 3) Breathable and comfortable: Pure cotton material reduces skin allergies and pressure.

[0027] 4) Economical and practical: Reusable, reducing medical costs;

[0028] 5) Easy to operate: Patients can adjust or change the equipment themselves, reducing the burden of nursing care. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] like Figure 1 As shown, the structure of this utility model includes: a strip-shaped body, on which multiple Velcro tabs and female tabs are disposed, including:

[0033] The outer left side of the strip body is provided with a first hook and loop fastener 1, and the inner right side is provided with a first hook and loop fastener 2 that matches the first hook and loop fastener 1.

[0034] Next to the first sub-attachment 1 of the Velcro on the left outer side of the strip body, there is also a second female Velcro attach 3 and a second sub-attachment 4 of the Velcro;

[0035] The outer right side of the strip body has a 1 / 2 width hook and loop third sub-attachment 5, and the inner side has a 1 / 2 width hook and loop fifth mother attachment 9, and a hook and loop third mother attachment 6 connected to the hook and loop third sub-attachment 5.

[0036] On the right outer side of the strip body, there are a fourth hook and loop fastener 7 and a fourth hook and loop fastener 8 located 5cm away from the third hook and loop fastener 5 and the third hook and loop fastener 6.

[0037] The strip is a long strip made of two layers of pure cotton fabric, 50cm in length and 5cm in width. Pure cotton fabric is highly breathable, absorbs and releases moisture quickly, and has antibacterial and anti-mildew properties, effectively preventing allergic reactions from prolonged use.

[0038] The first sub-attachment 1, second sub-attachment 4, third sub-attachment 5, and fourth sub-attachment 7 of the hook and loop fastener form a bristle anchoring layer; the first mother-attachment 2, second mother-attachment 3, third mother-attachment 6, fourth mother-attachment 8, and fifth mother-attachment 9 of the hook and loop fastener form a velvet-like outer layer. The initial fixation of the third sub-attachment 5 and the second mother-attachment 3, followed by the folding of the second sub-attachment 4 up to half of the second mother-attachment 3 and half of the fifth mother-attachment 9, forms a double-fixation structure for the dialysis catheter. This double-fixation structure allows for effective fixation over a long period, effectively preventing displacement or slippage of the dialysis catheter due to external forces.

[0039] The cooperation between the fourth sub-attachment 7 and the fourth mother-attachment 8 of the Velcro allows for adjustment of the tightness of the band to accommodate different patients' neck circumferences. The sub-attachment 7 can be adhered to the mother-attachment 8 according to the patient's neck circumference, thus adapting to different patients. The purpose of this design is to facilitate flexible adjustment based on the patient's neck circumference and the position of the dialysis catheter, ensuring that the fixation device fits snugly against the skin to prevent catheter dislodgement or displacement, while also reducing pressure on the patient's skin, improving comfort, and making the fixation device more user-friendly.

[0040] When the patient's neck circumference does not need adjustment, directly attach the sixth female Velcro patch 10 and the fourth female Velcro patch 7 to avoid the barbs anchoring layer pricking the skin.

[0041] The implementation process of the above embodiments is as follows:

[0042] The strap, or fixation strap, is wrapped around the patient's neck and initially secured by the first Velcro tab 1 and the first Velcro tab 2. Then, the third Velcro tab 6 wraps around the catheter, and the third Velcro tab 5 and the second Velcro tab 3 are used for initial fixation. The second Velcro tab 4 is then folded up and secured again to half of the second Velcro tab 3 and the fifth Velcro tab 9. The tightness of the fixation strap is adjusted according to the patient's neck circumference using the fourth Velcro tab 7 and the fourth Velcro tab 8.

[0043] The aforementioned device is designed with patient comfort, safety, effectiveness, and economy in mind. Compared to existing technologies, this embodiment not only boasts an aesthetically pleasing design but also ensures a high level of safety during use. Its operation is simple and intuitive, allowing patients to easily manage it themselves. When the dialysis catheter needs replacement, the patient can perform the procedure independently, and it can be reused after cleaning. The relatively low manufacturing cost makes it highly economical in clinical applications, with satisfactory results, thus possessing broad application value. It avoids the use of traditional adhesive tape and gauze for fixation, overcoming a series of problems associated with traditional methods, such as tape easily falling off, gauze becoming damp and causing contamination, patient allergies to adhesive tape, catheter slippage, and infection. It reduces the risk of unplanned extubation and device-related pressure injuries. It shortens nursing operation time and improves service efficiency: the use of Velcro for quick fixation and an elastic band adjustment structure avoids the increased workload caused by frequent tape changes, shortening the time nurses spend maintaining the tubing. Furthermore, the use of this device can significantly reduce catheter infection rates, the incidence of unplanned extubation, and patient hospitalization rates, thereby reducing patients' medical expenses, saving valuable medical resources, and improving the quality of nursing care.
