Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an adjustable long-term dialysis catheter fixation and protection bag. Background Technology

[0002] Long-term dialysis catheters generally use single-needle double-lumen catheters with two "Y"-shaped ends. The interfaces are sealed with heparin caps, and the exposed catheter outside the tunnel opening is in a free state. Traditional catheter fixation uses conventional adhesive tape fixation. The specific measures are: after disinfection, the catheter is wrapped with sterile gauze, secured with adhesive tape, and the catheter opening is covered with a medical dressing. The exposed free catheter is then covered with medical tape and attached to the front of the patient's pectoralis major muscle. It is mainly based on adhesive tape. The above fixation method has the following drawbacks: adhesive tape leaves adhesive tape marks after fixation, patients' skin is allergic to medical tape, and some patients still experience skin redness, swelling, unbearable itching, and rashes even after switching to 3M paper tape, which increases the patient's suffering. Scratching can also easily dislodge the catheter. Utility Model Content

[0021] This specific embodiment is an adjustable long-term dialysis catheter fixation and protection bag, the structural diagram of which is shown below. Figures 1-5As shown, the protective bag includes a bottom bag 1 and an upper bag 2 disposed above the bottom bag 1. One end of the upper bag 2 is fixedly connected to one end of the bottom bag 1. A second hook and loop fastener is fixedly connected to the outer surface of the other end of the bottom bag 1. A second hook and loop fastener is fixedly connected to the inner wall of the other end of the upper bag 2, which is used to cooperate with the second hook and loop fastener. The upper bag 2 is fixed on the bottom bag 1 to form a pocket for placing a tube. Two round holes 21 are opened on the upper bag 2, and an adjustable strap 3 is installed inside the round holes 21.

[0022] The adjustable strap 3 is made of braided rope, which is soft, skin-friendly, wear-resistant, strong, waterproof, and sweatproof. The adjustable strap 3 is made by leaving 70-80cm of the braided rope. One end of each of the two braided ropes is fixed in the two round holes 21 in the upper bag 2. The ends of the two braided ropes away from the upper bag 2 are joined together and tied with a square knot (also made of braided rope) to form a necklace-like structure. The square knot can be pushed and pulled freely. A knot is tied at the end of the braided rope away from the upper bag 2 to prevent the square knot from falling off the braided rope. When using this protective bag, the adjustable strap 3 is put around the patient's neck, and the braided rope is adjusted to a suitable length by pushing the square knot to shorten it, such as hanging around the neck like a necklace to fix the catheter. Therefore, the adjustable strap 3 can be adjusted to facilitate use by different patients.

[0023] The bottom bag 1 is equipped with a fixing component 4 for fixing the tube. There are two fixing components 4. Each fixing component 4 includes a wide fixing strap 41. One end of the wide fixing strap 41 is sewn to the bottom bag 1. The wide fixing strap 41 has a through groove. Each fixing component 4 also includes a thin fixing strap 42 that is fixedly connected to the wide fixing strap 41. The end of the thin fixing strap 42 away from the wide fixing strap 41 is fixedly connected to a first hook and loop fastener. The bottom bag 1 is fixedly connected to a first hook and loop fastener barbed surface that cooperates with the first hook and loop fastener.

[0024] The catheter is placed on the wide fixing band 41. Medical personnel hold the end of the thin fixing band 42 furthest from the wide fixing band 41 and wrap it around the catheter, then pass it through the slot in the wide fixing band 41. The thin fixing band 42 is then secured by the first Velcro surface of the thin fixing band 42 engaging with the first Velcro barbed surface of the bottom bag 1. This achieves catheter fixation. A schematic diagram of the wide fixing band 41 and the thin fixing band 42 wrapped around the catheter is shown in Figure 2. Figure 4 As shown, securing the catheter inside the pocket prevents the risk of catheter dislodgement and effectively increases the efficiency of catheter fixation.

[0025] The bottom bag 1, top bag 2, wide fixing strap 41 and thin fixing strap 42 are all made of cotton fabric. Cotton fabric is soft, comfortable and breathable, and is also suitable for sensitive skin caused by uremia.

[0026] In use, the catheter is first placed on the wide fixing strap 41 of the bottom bag 1. Then, the thin fixing strap 42 is wrapped around the catheter and fixed by the first hook and loop fastener surface and the first hook and loop fastener barbed surface. This achieves the fixation of the catheter. By setting two fixing parts 4, the catheter can be fixed at both ends of the pocket. After the catheter is fixed by the fixing parts 4, the other end of the upper bag 2 is pinched and flipped over to cover the fixing parts 4 and the catheter. After the upper bag 2 is flipped over, the inner wall of the other end of the upper bag 2 is attached to the bottom bag 1. At this time, the upper bag 2 is fixed to the bottom bag 1 with the cooperation of the second hook and loop fastener surface and the second hook and loop fastener surface. At this time, the upper bag 2 and the bottom bag 1 form a rectangular pocket. Then, the adjustable strap 3 is hung around the patient's neck. The adjustable strap 3 can be adjusted in length by flat knot. It can support the dialysis catheter according to the size of the patient's neck and can effectively fix it to the neck. It is comfortable and secure. The catheter is fixed inside the pocket and looks good.

[0027] In summary, this invention, by fixing the catheter inside the pocket and using cotton cloth for both the bottom pocket 1 and the upper pocket 2, avoids causing skin irritation or other adverse effects when in contact with the patient's skin. Therefore, it avoids adverse reactions such as residual adhesive on the skin surface, itching, allergies, and medical adhesive-related skin damage caused by traditional adhesive tape fixation, and increases patient comfort, thereby improving patient satisfaction.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
