Description

Technical Field

[0001] The utility model relates to the technical field of dialysis catheters for nephrology, in particular to a dialysis catheter for nephrology. Background Art

[0002] Dialysis is a separation and purification technology that separates small molecules from biomacromolecules by the principle of small molecules diffusing into water (or buffer) through a semipermeable membrane. Dialysis therapy is a treatment method that allows components (solutes or water) in body fluids to be discharged from the body through a semipermeable membrane. It can generally be divided into hemodialysis and peritoneal dialysis. Due to renal failure in some patients, the internal water cannot be discharged, resulting in excessive abdominal water accumulation and abnormal swelling. Therefore, a dialysis catheter for nephrology is needed to meet the current market demand. Although a variety of dialysis catheters have been produced on the market, in general, there are still many common problems. First, most of the existing dialysis catheters adopt an integrated structure instead of a detachable structure, which makes it impossible to disassemble and clean individual parts separately. Second, most of the existing dialysis catheters are not equipped with an adjustment sleeve, which makes it impossible to control the drainage rate. For this reason, we propose a dialysis catheter for nephrology to solve the above problems. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4 The utility model provides an embodiment: a dialysis catheter for nephrology, comprising a hose 1; a dialysis head 3, which is arranged at the right end of the hose 1; a connecting tube 4, which is arranged at the left end of the hose 1; an adjusting sleeve 8, which is slidably mounted on the hose 1; a chute 9, which is arranged inside the adjusting sleeve 8; a slider 10, which is slidably mounted inside the chute 9; an adjusting component, which is arranged inside the slider 10, and is used to adjust the position of the slider 10 in the chute 9;

[0018] Furthermore, both left and right ends of the hose 1 are provided with threads 2, and the dialysis head 3 and the connecting tube 4 are rotatably mounted inside the threads 2, such as Figure 3 As shown, this arrangement facilitates the subsequent removal of the dialysate head 3 and the connecting tube 4 from the left and right ends of the hose 1, so that the dialysate head 3 and the connecting tube 4 can be disinfected and cleaned for subsequent use.

[0019] Furthermore, a sliding sleeve 5 is slidably mounted on the hose 1, and straps 6 are arranged on both the front and rear sides of the sliding sleeve 5, a Velcro 7 is arranged on the upper side of the front strap 6, and a Velcro 7 is arranged on the lower side of the rear strap 6, such as Figure 1 As shown, the two sets of straps 6 and Velcro 7 are provided to facilitate tying the hose 1 to the patient's arm or the bed column, thereby preventing the hose 1 from being pulled off by external forces during use.

[0020] Furthermore, the adjustment component includes a movable groove 11, a spring 12, a limit block 13 and a limit groove 14. The lower end of the slider 10 is provided with a movable groove 11, and a spring 12 is movably installed inside the movable groove 11. The limit blocks 13 are movably inserted on both the front and rear sides of the movable groove 11. The convex head part of the limit block 13 is arc-shaped. The front and rear sides of the adjustment sleeve 8 are arrayed with multiple groups of limit grooves 14, and the limit grooves 14 are adapted to the convex head part of the limit block 13, such as Figure 4 As shown, the position of the slider 10 in the slide groove 9 can be controlled by setting the adjustment component, and the hose 1 can be squeezed to different degrees, so that the flow rate of the liquid in the hose 1 can be controlled.

[0021] Furthermore, the adjusting sleeve 8 has grooves 15 symmetrically formed inside, and two sets of limit plates 16 are fixedly mounted on the lower end of the slider 10. The two sets of limit plates 16 slide inside the grooves 15. Figure 4 As shown, the stability of the slider 10 when sliding in the slide groove 9 is ensured by the provision of two sets of limit plates 16 .

[0022] Working principle: When the device is used, the staff connects the dialysis head 3 and the connecting tube 4 provided at the left and right ends of the hose 1 to the medical device to be used, and then the staff uses two sets of straps 6 to tie the patient's arms, or ties the two sets of straps 6 to the pillars of the bed. Then the staff uses two sets of Velcro 7 to adjust according to the thickness of the patient's arms, and connects the two sets of straps 6 to each other, and then the hose 1 can be used. When it is necessary to adjust the flow rate of the liquid in the hose 1, the staff pushes the slider 10 to the right inside the chute 9, and the two sets of limit blocks 13 are pushed to the opposite side inside the movable groove 11. When sliding sideways, the opposite side of the two groups of limit blocks 13 squeezes the spring 12, and the convex head parts of the two groups of limit blocks 13 move out from the inside of the two groups of limit grooves 14. When the two groups of limit blocks 13 move to the next group of symmetrically opened limit grooves 14, the two groups of limit blocks 13 are ejected to the front and rear sides in the movable groove 11 by the elastic force of the spring 12, and then the convex head parts of the two groups of limit blocks 13 are inserted into the inside of the two groups of limit grooves 14, and then the position of the slider 10 is limited and fixed, and the lower end of the slider 10 squeezes the hose 1, so that the flow rate of the liquid in the hose 1 becomes smaller. The above is the entire working principle of the utility model.
