[0002] Hemodialysis (HD) is an important kidney replacement therapy for patients with acute and chronic renal failure. This method removes metabolic waste from the body by introducing blood from the patient's body to the outside, purifying the blood, and then reinfusing the purified blood into the patient's body. During the entire dialysis process, the dialysis catheter plays a key role as the access for blood in and out of the body.

[0003] During the dialysis treatment, the connection of the dialysis catheter and the heparin cap is crucial. However, the heparin cap may be affected by external forces during use due to patient activity, prolonged catheter indwelling time, and other external factors, leading to accidental detachment. To address this issue, medical staff usually wrap the heparin cap and catheter with gauze and then use adhesive tape to fix them.

DETAILED DESCRIPTION

[0013] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor all belong to the protection scope of the utility model. The experimental methods in the following embodiments are conventional methods, and the materials, reagents and the like used in the following embodiments can be obtained from commercial channels unless otherwise specified.

[0014] Please refer to Figure 1 And Figure 2As shown, this utility model provides a heparin cap protection device, including a dialysis catheter infusion end 1. The right end of the dialysis catheter infusion end 1 is connected to a heparin cap 11 by a thread. A nylon opening sleeve 2 is movably sleeved on the outside of the heparin cap 11. The dialysis catheter infusion end 1 is located inside the nylon opening sleeve 2. Assisting planes 21 are provided on both the upper and lower sides of the nylon opening sleeve 2. An adjusting main bar 22 is fixedly installed on the top of the assisting plane 21. A circular locking bar 23 is fixedly installed in the middle of the end of the adjusting main bar 22 away from the nylon opening sleeve 2. A first magic velvet noodle 24 is fixedly installed in the middle of the outer side of the adjusting main bar 22. A first magic hook noodle 25 is fixedly installed on the inner side of the circular locking bar 23. A positioning bar 26 is fixedly installed on the right end of the nylon opening sleeve 2. A second magic hook noodle 27 is fixedly installed on the left side of the positioning bar 26 close to the top. A second magic velvet noodle 28 is fixedly installed on the outer side of the adjusting main bar 22 close to the right end.

[0015] In this case, during use, the heparin cap 11 is threadedly connected to the right end of the dialysis catheter infusion end 1. The nylon opening sleeve 2 is movably fitted onto the outside of the dialysis catheter infusion end 1 and the heparin cap 11. The inner right side of the nylon opening sleeve 2 contacts the right end of the heparin cap 11. The adjusting main bar 22 and the ring locking bar 23 are tightened, and the first magic hook noodle 25 is attached to the first magic fleece noodle 24. The nylon opening sleeve 2 deforms under the tension of the adjusting main bar 22 and the ring locking bar 23, so that after the nylon opening sleeve 2 deforms, its inner side is in close contact with and locked to the dialysis catheter infusion end 1. The plasticity of the nylon opening sleeve 2 allows for the fitting of dialysis catheter infusion ends 1 of different specifications. After locking and fixing, the positioning strip 26 is tightened and adjusted. The positioning strip 26 causes the center position of the round hole at the right end of the nylon opening sleeve 2 to change, so that the center position of the round hole is close to the center position of the round hole at the right end of the heparin cap 11. The tightened positioning strip 26 is then attached to the second magic hook noodle 28 by the second magic velvet noodle 27, so that the right end of the nylon opening sleeve 2 and the right end of the heparin cap 11 are in closer contact. The combination of the ring locking strip 23 and the positioning strip 26 not only strengthens the connection between the heparin cap 11 and the infusion end 1 of the dialysis catheter, but also makes the operation simple and quick, saving a lot of medical resources and labor costs. At the same time, the fixation effect is significant and the efficiency is extremely high.

[0016] A circular hole is provided at the center of the right end of the nylon open sleeve 2, and the right end of the circular hole passes through the right side of the positioning strip 26.

[0017] This facilitates the insertion of the needle through the round hole into the heparin cap 11.

[0018] The length of the circular locking strip 23 is close to the circumference of the nylon open sleeve 2.

[0019] This allows the first magic hook noodle 25 to adhere to the first magic velvet noodle 24 at the appropriate length.

[0020] The inner side of the nylon opening sleeve 2 is fixedly provided with a friction strip, the friction strip, the circular ring locking strip 23 and the first magic velvet strip 24 are in the same line.

[0021] The friction strip increases the friction resistance of the inner side of the nylon opening sleeve 2 in contact with the dialysis catheter infusion end 1 when the nylon opening sleeve 2 is deformed.

[0022] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
