Description

Technical Field

[0001] The present application relates to the technical field of medical auxiliary devices, and in particular to a dialysis catheter anti-slipping fixing soft clip, which can not only fix and prevent the arteriovenous line of the dialysis catheter from slipping off, but also prevent the catheter puncture needle from being accidentally pulled out. Background Art

[0002] The arteriovenous catheter may be easily pulled out if the patient turns over or pulls involuntarily or when the patient is not conscious, or the arteriovenous catheter may be pulled out due to inertia, which may bring many health risks to the patient. For example:

[0003] 1. Bleeding: During the dialysis process, patients may experience bleeding and bleeding due to their own catheters. If the dialysis catheter is not fixed properly, it may cause vascular damage or even bleeding, and in severe cases, cause hemorrhagic shock;

[0004] 2. Infection: Long-term dialysis patients have low immunity. They may be infected due to their own reasons during dialysis. For example, if the patient coughs or sneezes violently or has constipation during dialysis, infection may occur if the catheter is pulled out and exposed to the outside world, disinfected, and then reinserted;

[0005] 3. Pain: During the dialysis process, due to the patient's own reasons, such as the patient's large movements, irritability, etc., the dialysis catheter may become loose or fall off. In severe cases, skin hematoma may occur. Therefore, accidental falling off of the catheter will cause pain to the patient.

[0006] 4. Prolonging the treatment time: For patients with more serious conditions, since the disease itself is a kind of pain and torture, if the catheter or puncture needle and other instruments fall off and are repeatedly injected, it will bring greater pain and inconvenience to the patient, which is not conducive to the patient's rehabilitation treatment, thereby prolonging the treatment time.

[0007] Therefore, in order to solve the problem that catheters and puncture needles are easy to fall off, bandages, adhesive tapes, etc. are usually used to fix catheters and puncture needles in clinical practice. Bandages are easy to loosen, and adhesive tapes must be attached tightly. However, due to the elasticity of the skin itself, they will gradually lose their stickiness after a period of use, resulting in loosening. Therefore, the existing fixation methods for dialysis catheters and puncture needles are easy to loosen. Repeated fixation not only brings trouble to patients, but also increases the workload of medical staff and increases medical costs. Therefore, it is necessary to propose a new technical solution to solve the problems existing in the existing technology. Utility Model Content

[0013] Furthermore, a plurality of anti-slip teeth are arranged on the surface of the third clamping block, and a plurality of anti-slip teeth are arranged on the surface of the fourth clamping block. The second spring pressing plate is used to realize the relative clamping or relative release of the second fixed wing plate and the third fixed wing plate. The third clamping block and the fourth clamping block cooperate to form a clamping position.

[0014] Furthermore, the third clamping block and the fourth clamping block are both cylindrical blocks, and the outer diameter of the third clamping block is smaller than the outer diameter of the fourth clamping block.

[0016] Furthermore, the first pressing plate is inclined toward the second pressing plate, and the second pressing plate is arranged horizontally.

[0017] Furthermore, the second fixed wing plate includes a first horizontal plate section for installing the second elastic clamping plate and the third clamping block, a second horizontal plate section for connecting the second connecting seat, and an intermediate inclined plate for connecting the first horizontal plate section and the second horizontal plate section, and the horizontal height of the first horizontal plate section is higher than that of the second horizontal plate section.

The catheter is easy to use, and can prevent slippage and displacement. When the dialysis patient is undergoing dialysis, the catheter can be fixed on the arteriovenous line of the dialysis catheter, reducing the risk of adverse events such as the patient turning over or pulling to pull out the arteriovenous catheter involuntarily or when the patient is not conscious, or the arteriovenous catheter is pulled out due to inertia. The use is simple, easy, effective and reliable.

People who are proficient in the technology can easily understand the advantages and effects of the present invention from the contents presented in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0032] The terms such as "upper", "lower", "left", "right", "middle" etc. used in this application are usually used to facilitate intuitive understanding by comparing with the drawings, and are not absolute limitations on the positional relationship in the actual product. Without departing from the technical concept disclosed in this application, changes in these relative positional relationships should also be regarded as the scope of this application.

[0033] The catheter anti-slipping fixing soft clip provided in the present application can be used to fix the arteriovenous line of the dialysis catheter during dialysis patients, reducing the risk of adverse events such as the patient turning over or pulling to pull out the arteriovenous catheter involuntarily or when the patient is not conscious, or the arteriovenous catheter is pulled out due to inertia. The soft clip provided in the present application can directly fix the arteriovenous line to the patient's clothing, which is simple, easy, effective and reliable, and can also reduce the risk of coagulation caused by folding and twisting of the line. For fistula patients, it can also be fixed to the clothing on the patient's fistula-side arm, reducing the risk of the puncture needle being pulled out due to the patient raising his hand, turning over, or the bed rails slipping. The structural principle of the catheter anti-slipping fixing soft clip provided in the present application is described in detail below.

[0034] The catheter anti-dropout fixing soft clip provided in the present application mainly comprises a first fixing wing plate 1, a second fixing wing plate 2 and a third fixing wing plate 3 which are arranged at intervals from top to bottom, wherein: Figure 2 A first connecting seat 11 is provided on one side of the lower surface of the first fixed wing plate 1, and a first elastic clamping plate 12 is provided on the other side of the lower surface of the first fixed wing plate 1. A first pressing plate 16 for clamping and pressing is formed on the first fixed wing plate 1. The first pressing plate 16 is located on one side of the first connecting seat 11, and the first pressing plate 16 is inclined toward the second pressing plate 26.

[0035] A second connecting seat 21 is set on one side of the lower surface of the second fixed wing plate 2, and a third clamping block 25 is set on the other side of the lower surface of the second fixed wing plate 2. A second elastic clamping plate 22 adapted to clamp the first elastic clamping plate 12 is set on one side of the upper surface of the second fixed wing plate 2. A second pressing plate 26 for clamping and pressing is formed on the second fixed wing plate 2. The second pressing plate 26 is located on one side of the second connecting seat 21. The first pressing plate 16 and the second pressing plate 26 are arranged opposite to each other up and down, and the second pressing plate 26 is arranged horizontally.

[0036] A third connection seat 31 is provided on one side of the upper surface of the third fixed wing plate 3, and a fourth clamping block 32 adapted to clamp the third clamping block 25 is provided on the other side of the upper surface of the third fixed wing plate 3. A first rotating shaft 14 adapted to rotate and connect with the first connection seat 11 and a second rotating shaft 23 adapted to rotate and connect with the second connection seat 21 are formed on the third connection seat 31, a first spring pressing piece 15 is provided on the first rotating shaft 14, a second spring pressing piece 24 is provided on the second rotating shaft 23, and the first rotating shaft 14 is provided above the second rotating shaft 23. The first spring pressing piece 15 and the second spring pressing piece 24 in the present application can be low-cost elastic parts such as torsion springs that can provide elastic force to realize the clamping and releasing action.

[0037] Therefore, see Figure 1 In the present application, a first clamping mechanism located at the upper part is formed by a first fixed wing plate 1, a second fixed wing plate 2, a first rotating shaft 14, and a first spring pressing plate 15, and a second clamping mechanism located at the lower part is formed by a second fixed wing plate 2, a third fixed wing plate 3, a second rotating shaft 23, and a second spring pressing plate 24. The invention has multiple clamping positions in one body. The catheter is clamped by the clamping mechanism at the upper part, and the patient's clothes or other fixed positions are clamped by the clamping mechanism at the lower part to realize the fixation of the catheter anti-slipping soft clip. The invention is easy to use and can prevent slipping and displacement.

[0038] In one embodiment, two clamping grooves 13 are respectively provided on the surface of the first elastic clamping plate 12 and the surface of the second elastic clamping plate 22, and a clamping groove 13 on the first elastic clamping plate 12 and a clamping groove 13 on the second elastic clamping plate 22 are aligned to form a clamping hole for fixing the catheter. Therefore, the soft clamp provided in the present application can fix multiple catheters. The first elastic clamping plate 12 and the second elastic clamping plate 22 can be made of medical grade silicone or sponge material.

[0039] In one embodiment, a plurality of anti-slip teeth are arranged on the end faces corresponding to the third clamping block 25 and the fourth clamping block 32, and a plurality of anti-slip teeth are arranged on the end faces corresponding to the fourth clamping block 32 and the third clamping block 25, and the third clamping block 25 and the fourth clamping block 32 cooperate to form a clamping position.

[0040] In one embodiment, the third clamping block 25 is a cylindrical block, the fourth clamping block 32 is a cylindrical block, the outer diameter of the third clamping block 25 is smaller than the outer diameter of the fourth clamping block 32, the third clamping block 25 and the fourth support block can be hollow cylinders, and a circle of anti-slip teeth is set on the end surface of the side wall of the hollow cylinder. The third clamping block 25 and the fourth support block can be integrally formed with the second fixed wing plate 2 and the third fixed wing plate 3 respectively, or can be bonded, which is lower in cost than fixing by screws or the like.

[0041] In one embodiment, the second fixed wing plate 2 includes a first horizontal plate section for installing the second elastic clamping plate 22 and the third clamping block 25, a second horizontal plate section for connecting the second connecting seat 21, and an intermediate inclined plate for connecting the first horizontal plate section and the second horizontal plate section. The horizontal height of the first horizontal plate section is higher than that of the second horizontal plate section. The height difference is set to ensure that the spacing between the first pressing plate 16 and the second pressing plate 26 is increased, which is convenient for the manual pressing operation distance. In the present application, the second elastic clamping plate 22 and the third clamping block 25 are staggered on the second fixed wing plate 2, so that the upper clamping mechanism will not block the lower clamping mechanism, so that medical staff can intuitively see the clamping state of the two clamping mechanisms. The first pressing plate 16 and the second pressing plate 26 are provided with anti-slip grooves, which are convenient for medical staff to use and not easy to slip.

[0042] In one embodiment, the anti-dropout fixing soft clip can be used after the patient is on the dialysis machine. The method of use is as follows:

[0043] 1. Disinfect or replace according to the instructions before and after each use to reduce the risk of infection;

[0044] 2. Determine the fixing position: Select a suitable catheter fixing position, and the medical staff fix the clamping mechanism at the bottom of the fixing clip to one side of the patient's clothing through the arc fixing method;

[0045] 3. Install the soft clip: Place the anti-dropping fixed soft clip on the selected fixed point, make sure the soft clip fits tightly against the catheter, and then press and fix it;

[0046] 4. Check the fixation effect: ensure that the soft clip is firmly fixed and the catheter is not displaced or fallen off;

[0047] 5. After dialysis, gently loosen the clamp and remove it carefully to avoid damaging the skin or catheter.

[0048] In the present application, the first fixed wing plate 1 and the second fixed wing plate 2 are fitted and clamped to fix the arteriovenous catheter by the first elastic clamping plate 12 and the second elastic clamping plate 22. The first elastic clamping plate 12 and the second elastic clamping plate 22 can be made of medical grade silicone material, which has good anti-slip and anti-skid properties, elastic flexibility, and maintains constant pressure and ductility. Sponge material can also be used. In addition, in the present application, the first fixed wing plate 1, the second fixed wing plate 2 and the third fixed wing plate 3 are fitted and fixed by a rotating shaft and a spring pressing plate. The connecting seat on each fixed wing plate is made of medical grade silicone material, which has good biocompatibility and can reduce allergic reactions to contact with the skin. At the same time, the toothed fixed end formed by the third clamping block 25 and the fourth clamping block 32 is clamped and fixed on the patient's clothes. The toothed fixed end and the arteriovenous catheter clamping part form a certain safe adjustment range to avoid safety hazards for operators or patients.

[0049] In the present application, the lower clamping part of the catheter anti-slipping soft clamp is designed to be serrated, which has a better fixing effect and a stable clamping force to ensure that it will not fall off, and the opening and closing amplitude of the serrated fixing end is controlled by the second spring pressure sheet 24 to ensure the safety of the serrated end for the operator and the patient; the upper clamping part of the catheter anti-slipping soft clamp constitutes the arteriovenous pipeline fixing end, which is designed to be adaptively clamped and uses silicone or sponge material. It can adapt to the changes in pipeline diameter caused by thermal expansion and contraction to provide a stable clamping force, and has sufficient elasticity and durability to withstand repeated use without being easily damaged. At the same time, it has an anti-slip effect and increases friction to ensure that the soft clamp can still firmly fix the catheter when the patient moves or adjusts his position.

[0050] The catheter anti-dislocation fixing soft clip provided in the present application has a simple structure, is lightweight and portable, and is convenient for medical personnel to operate. For patients, this soft clip is small and light, and does not change the patient's comfort level, nor does it cause additional pressure or discomfort.

[0051] Compared with the prior art, this application has the following advantages:

[0052] 1. Compared with traditional tape fixation, the dialysis catheter anti-dislocation fixation soft clip provided in this application is safer and more stable, reduces the probability of adverse events such as unplanned extubation, and demonstrates the humanized and rational design concept of medical equipment design.

[0053] 2. This application uses materials such as silicone or sponge as the catheter clamping part, which makes it have good durability, stability and anti-allergy, can adapt to the skin conditions and body shapes of different patients, reduce the pressure and friction on the skin during fixation, and improve the comfort of patients.

[0054] 3. Traditional fixation methods may have risks such as catheter falling off, displacement, bending and twisting, posing potential threats to the patient's life safety. The catheter anti-slip fixation soft clip provided in this application has additional functions such as anti-slip, anti-slip, and anti-dialysis pipeline bending and twisting in addition to the basic fixation function. These functions not only meet the basic needs of the dialysis process, but also improve the medical quality and service level, reduce the occurrence of adverse events, improve safety, and bring real benefits to patients.

[0055] 4. Medical staff can quickly master the use of this application and improve work efficiency. At the same time, its light size and easy-to-clean characteristics also make it more flexible and convenient in clinical applications.

[0056] 5. From a cost perspective, the catheter anti-dislocation fixation soft clip provided in this application also has significant economic advantages. Compared with traditional fixation methods, such as bandages, adhesive tapes, etc., the soft clip has a longer service life and extremely low maintenance costs. It can be reused after disinfection, which can save some economic expenses for the department.

[0057] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0058] The above is a relatively specific and detailed description of the present application through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
