Description

Technical Field

[0001] The utility model relates to the technical field of nursing devices for hemodialysis, in particular to a hemodialysis deep vein catheter fixing device with a pressure-resistant structure. Background Art

[0002] Hemodialysis deep venous catheters are often used in hemodialysis and other blood purification therapies. When used, two catheters are inserted into the veins, one catheter is used to draw out blood, and the other catheter is used to return the purified blood to the patient. The hemodialysis deep venous catheter needs to be fixed to the patient's body near the insertion site, and tape is often used to stick the hemodialysis deep venous catheter to the patient.

[0003] The existing method of fixing deep venous catheters for hemodialysis has some disadvantages. First, the tape is used to position the catheter, which may lead to insufficient fixation and inconvenience in use. Second, sweat or water on the skin may cause the tape to be less sticky, which may easily lead to displacement of the catheter. Third, there is no protection or pressure resistance for the positioning position, which may easily cause injury to the patient. Utility Model Content

[0012] Preferably, a protective sheet is provided on the upper portion of the bonding tape, and the lower portions of both ends of the protective sheet are respectively fixedly connected to the upper ends of the limiting blocks.

[0013] Compared with the prior art, the utility model has the following beneficial effects: it is easy to position the catheter, easy to prevent slipping, and has good protection;

[0014] (1) The two catheters can be placed at the lower ends of the two fitting belts respectively. Since the lower part of the fitting belt is an arc-shaped protrusion, the friction between the fitting belt and the catheter can be increased, thereby firmly positioning the catheter. Flexible anti-slip protrusions are evenly arranged at the lower end of the fixing belt, which can improve comfort while preventing the fixing device from being displaced. According to actual needs, the second Velcro male patch and the second Velcro female patch can cooperate and fit with each other to bind the fixing device to the body, which is convenient for firmly positioning the catheter.

[0015] (2) The reinforcing belt can be tied on a suitable part of the patient's body by cooperating and fitting the male Velcro patch and the female Velcro patch together, and the catheter can be passed through the lower part of the connecting belt. The lower end of the connecting belt is evenly provided with flexible anti-skid convex strips, and the anti-skid convex strips are staggered horizontally and vertically, which is beneficial to improve the anti-skid performance of the fixing device and is easy to prevent slipping.

[0016] (3) If an external force accidentally hits or squeezes the protective sheet, the protective sheet will compress the spring through the limit block. Since the spring is elastic, the spring inside the coupling head has a buffering and protective effect on the protective sheet, and the protective performance is good.
