Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to an improved U-shaped fixing belt for a hemodialysis catheter. Background Art

[0002] The hemodialysis device is a medical device that uses the principle of semipermeable membrane to exchange or discharge various harmful and redundant metabolic wastes and excessive electrolytes in the patient's blood through diffusion, convection and filtration, so that the patient's body environment is close to that of a normal person, thereby achieving the purpose of purifying the blood. It is mainly used clinically to treat acute and chronic renal failure caused by various reasons and some toxic diseases. Therefore, it is necessary to establish an extracorporeal blood circulation device through a puncture needle and an extracorporeal circulation pipeline to maintain a hemodialysis process of about 4 hours. The traditional simple device for fixing the catheter during hemodialysis is to use a clip or pliers to fix the catheter on the bed sheet or clothes. This method of fixing the catheter usually has the following problems: First, the fixation is not firm enough, which can easily cause the catheter to be pulled, thereby causing the puncture needle to come out; second, this method of fixing is prone to cause the puncture needle to slip out of place or come out under the action of gravity, causing accidental blood loss, which may create the possibility of medical risks. At the same time, after 4 hours of dialysis, patients often feel weakness and discomfort in the upper limbs; third, the use of clips or pliers increases additional resource expenditures and may also cause cross-infection. It needs to be replaced by one person at a time, and requires additional disinfection equipment and equipment and tools for detecting the disinfection effect. In response to the problems existing in the traditional method of fixing the catheter, various devices and equipment for fixing the catheter have appeared in the existing market, but most of them have the problems of complex structure, high cost and poor practicality. Summary of the invention

[0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide an improved fixing belt for hemodialysis catheter, which is specifically achieved through the following technical solutions:

[0004] The improved fixing belt for hemodialysis catheter comprises an elastic fixing belt body, the two ends of which are connected by Velcro, and a hook and loop assembly is arranged on one end of the elastic fixing belt body for fixing the hemodialysis catheter. The elastic fixing belt body is used to fix the catheter, which is easy to implement, low in cost and highly practical.

[0005] Furthermore, the hook body assembly includes a fleece surface arranged on one end of the elastic fixing belt body, a hook surface arranged corresponding to the fleece surface, the middle part of the hook surface is sewn on the fleece surface, and the two ends of the hook surface are free ends. The arrangement of the hook body assembly facilitates the U-shaped fixation of the catheter and reduces the gravity of the catheter.

[0006] Furthermore, the width of the fur surface provided on one end of the elastic fixing belt body is the same as that of the elastic fixing belt body, one end of the fur surface is flush with the end of the elastic fixing belt body, and the surrounding of the fur surface is fixed to the elastic fixing belt body by sewing. This arrangement makes the entire fixing belt structure neat, not complicated, convenient and practical.

[0007] Furthermore, the size of the hook surface matches the size of the hair surface.

[0008] Furthermore, the male and female surfaces of the Velcro are arranged on both sides of the elastic fixing belt body, so that the fixing belt can be put on the patient's arm for use, which increases the convenience of use.

[0009] The utility model has a simple structure and low cost, and is convenient for each patient to prepare a copy for repeated use. By adding a hook body component to the fixing belt, the U-shaped fixation of the catheter is increased. This fixing method can not only increase the firmness of the fixation but also resist the traction of the catheter, so that the traction has a certain buffer force, reduce the probability of accidental blood loss caused by the puncture needle coming out, provide medical safety protection, and at the same time avoid the patient's feeling of weakness, soreness and discomfort in the upper limbs.

[0014] The present invention is further described below in conjunction with the accompanying drawings in order to better understand the present technical solution.

[0015] like Figure 1-3 As shown, the improved fixing belt for hemodialysis catheter of the utility model comprises an elastic fixing belt body 1. The elastic fixing belt body 1 is in the shape of a rectangular strip as a whole and can be prepared separately, so that one person has one belt to avoid infection. No additional disinfection facilities are required and only regular cleaning is required. An arteriovenous fistula tourniquet can also be used instead to achieve the purpose of one belt for multiple uses. The two ends of the elastic fixing belt body 1 are connected by Velcro 2, and the male and female surfaces of the Velcro 2 are respectively arranged on the two side surfaces of the elastic fixing belt body 1. This arrangement makes it easy to put the elastic fixing belt body 1 on the patient's arm and then fix it, which is convenient and quick to use.

[0016] A hook and loop assembly 3 is also provided on one end of the elastic fixing band body 1 for fixing the hemodialysis catheter. The hook and loop assembly 3 includes a loop surface 301 provided on one end of the elastic fixing band body 1 and a hook surface 302 provided corresponding to the loop surface 301. The size of the hook surface 302 matches the size of the loop surface 301. The middle of the hook surface 302 is sewn on the loop surface 301, and the two ends of the hook surface 302 are free ends. The width of the loop surface 301 provided on one end of the elastic fixing band body 1 is the same as the width of the elastic fixing band body 1. One end of the loop surface 301 is flush with the end of the elastic fixing band body 1, and the four sides of the loop surface 301 are fixed to the elastic fixing band body 1 by sewing.

[0017] The utility model can realize adding a U-shaped fixed passage to the hemodialysis catheter by simply adding a hook body component 3 to the elastic fixing belt body 1, and at the same time, the fixing firmness is increased. Due to the U-shaped fixation of the catheter, a certain catheter traction can be resisted, so that the traction has a certain buffering force, and the puncture needle is avoided from coming out. At the same time, after the catheter is fixed in the U shape, the unfixed length of the catheter is reduced, which plays a role in reducing the gravity of the catheter, so that the patient will not feel weakness, soreness and discomfort in the upper limbs after 4 hours of dialysis, and the occurrence of the puncture needle slipping out of place can also be avoided.

[0018] When the utility model is used, the elastic fixing belt body 1 is wrapped around the patient's arm and fixed by the Velcro 2. The catheter first passes through the fur surface 301 on one side of the sewing part, and then the catheter position is fixed by the adhesion of the hook surface 302 and the fur surface 301. After the catheter passes through, it is bent into a U shape and passes through the fur surface 301 on the other side of the sewing part. The catheter is fixed again by the adhesion of the hook surface 302 and the fur surface 301, that is, the U-shaped fixation of the catheter is completed. Although the device has a simple structure, it has a good use effect, strong practicality, and is convenient and quick to use.
