TECHNICAL FIELD
[0001] The utility model relates to the technical field of anti-seepage bandage, specifically to a hemodialysis anti-seepage bandage. BACKGROUND
[0002] The hemodialysis anti-seepage bandage is mainly used for hemostasis and fixation during hemodialysis and after the end of dialysis. When the arteriovenous fistula is subjected to a great impact when the dynamic and static vein needle is pulled out at the end of dialysis, the bandage can help fix the cotton ball or gauze at this time, ensuring that they are firmly fixed at the puncture site, thereby achieving the hemostasis effect.
[0003] Some hemodialysis patients have puncture points in special positions such as joints and upper arms, and the fixed bandage is prone to displacement after getting off the machine, which drives the cotton ball or gauze under the bandage to move synchronously and separate from the puncture point, thereby causing the consequence of blood loss due to seepage. In addition, seepage means that blood has direct contact opportunities with the external environment, increasing the risk of invasion of bacteria, viruses and other microorganisms. If the seepage point cannot be treated in time and effectively, it may cause infection at the puncture point and even more serious systemic infection. SUMMARY
[0004] The utility model aims to provide a hemodialysis anti-seepage bandage to solve the problems raised in the background art.
[0005] To solve the above technical problems, the utility model provides the following technical scheme: a hemodialysis anti-seepage bandage, comprising:
[0006] The bandage has one end as a terminal end and the other end as a traction end. The terminal end is provided with a buckle loop. The end of the traction end is reversely pulled and fixed after passing through the buckle loop, forming a binding space. The size of the binding space is adjustable.
[0007] The inner side wall of the terminal end is provided with a pressing protrusion. The pressing protrusion is used for pressing on the puncture point.
[0008] The bandage has an enlarged part. The enlarged part is a hollow structure. The inner wall of the hollow structure is provided with a mesh elastic net. The mesh elastic net is used for adhering to the outer wall of the elbow joint.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This embodiment provides a hemodialysis anti-leakage strap 1, such as... Figure 1 As shown, the device includes a strap 1, with one end being an end 1A and the other end being a traction end 1B. End 1A has a loop, which is a rectangular frame 3. One end of the frame 3 is fixedly connected to end 1A of the strap 1. The end of traction end 1B passes through the loop and is pulled in the opposite direction and fixed, forming a binding space. A pressing protrusion 13 is provided on the inner wall of end 1A. The pressing protrusion 13 is used to press at the puncture point. During binding, according to the arm size of the hemodialysis patient, the end of traction end 1B passes through the loop and is pulled in the opposite direction to tighten the strap 1, i.e., along... Figure 2 Traction is applied in the direction indicated by the middle arrow M, while ensuring that the pressing protrusion 13 is pressed at the interlacing point. The outer wall of the traction end 1B is provided with a hook and loop fastener 11 and a hook and loop fastener 12. The hook and loop fastener 11 and the hook and loop fastener 12 are adhered together to adjust the binding space, ensuring that the strap 1 can be firmly bound to the arm. Suitable for upper arm binding of patients.
[0024] In some hemodialysis patients, because the puncture site is located at the elbow joint, the fixation bandage 1 is prone to shifting after disembarking. This shift can cause the hemostatic cotton ball or gauze under the bandage 1 to move away from the puncture site, resulting in bleeding. Therefore, the bandage 1 has an enlarged portion 1C, such as... Figure 1 and Figure 2 As shown, the enlarged part 1C has a hollow structure, and the inner wall of the hollow structure is provided with an elastic mesh 2 with mesh holes. When the puncture point is located in the elbow crease, the bandage 1 is wrapped around the elbow joint. The hollow structure of the enlarged part 1C needs to be attached to the outer wall of the elbow joint. The elbow joint will be embedded in the hollow structure. At the same time, the elastic mesh 2 is highly attached to the skin surface of the elbow joint, which can effectively prevent the bandage from slipping at the elbow joint, causing the pressing protrusion 13 to fall off the hemostatic cotton cloth and resulting in bleeding at the puncture point.
[0025] It is important to note that after the patient is discharged from the machine, the bandage 1 should be loosened periodically (e.g., every 5 minutes) to check for bleeding at the injection site. If there is no bleeding, the bandage 1 can be removed after a period of time (e.g., 20 minutes). If there is bleeding, the bandage 1 should be quickly re-applied until the bleeding at the injection site stops.
[0026] Additionally, the elastic net 2 can be made of spandex or latex. Spandex is a highly elastic synthetic fiber that provides good tensile strength and resilience. Latex offers excellent elasticity and conformability. Both spandex and latex materials can fit snugly against the skin, reducing slippage of the strap 1.
[0027] To further enhance the binding stability of the strap 1, at least four extension straps 4 are fixedly connected to the outer wall of the enlarged part 1C. Two extension straps 4 form a group, and the two groups of extension straps 4 are located on both sides of the strap 1, as shown below. Figure 4 As shown, four extension straps 4 are arranged on both sides of the binding strap 1. The two extension straps 4 in the same group are set towards the end 1A and the traction end 1B respectively. After the binding strap 1 is tied to the puncture point, the two extension straps 4 on the same side can be tied together by wrapping around the arm to achieve double fixation and prevent displacement.
[0028] Of course, you can also use two extension straps 4 in the same set to wrap around the arm and tighten them, then attach them with Velcro.
[0029] Example 2 differs from Example 1 in that: Figure 2 and Figure 3 As shown, the buckle has a rotating pin 35 connected to the end 1A of the strap 1, an extension end 31 fixed to one end of the rotating pin 35, an extension end 34 rotatably disposed at the other end of the rotating pin 35, and a rotating rod 32 rotatably disposed on the inner side wall of the end of the extension end 34. The space between the rotating pin 35, the extension end 31, the extension end 34, and the rotating rod 32 is the insertion space for the traction end 1B. Moreover, the end of the rotating rod 32 is rotatably provided with a locking post 36, and the upper side wall of the end of the extension end 31 is provided with a locking notch 33 for engaging with the locking post 36.
[0030] When binding strap 1, first rotate the rotating rod 32 together with the extension end 34 around the position where it rotates with the rotating pin 35, that is, according to... Figure 2 Lift the rod in the direction indicated by arrow Q, causing the locking pin 36 to disengage from the locking notch 33. This disengages the rotating rod 32 from the extension end 31, creating a notch on the side of the insertion space. This allows the traction end 1B to be inserted laterally. Then, rotate the rotating rod 32 along with the extension end 34 in the opposite direction around the position where it rotates with the rotating pin 35, locking the locking pin 36 into the locking notch 33. This closes the notch in the insertion space again, preventing the traction end 1B from disengaging laterally and thus ensuring the bandage 1 is securely fastened. Finally, pull the end of the traction end 1B through the loop and tighten the bandage 1 in the opposite direction to secure it at the puncture point, preventing bleeding.
[0031] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
