Special tourniquet for dialysis catheter

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to special tourniquet of dialysis catheter is special to carry out hemostasis by compression's band behind putting into the dialysis catheter operation to the patient that will carry out hemodialysis treatment.

Background

When a patient is undergoing a hemodialysis treatment, a vascular access needs to be established first. In clinic, the dialysis catheter access is established by placing a dialysis catheter into a certain central vein of a patient through an operation (dialysis catheter placement operation). The most common sites of insertion of dialysis catheters are: about 2cm outside the neck or below the groin (left and right sides: four points in total). Due to the operation and the influence of various factors, bleeding (bleeding or hematoma) often occurs to the wound within 24 hours after the dialysis catheter is placed in the wound, and the incidence rate is about 7-20%. Because of the special surgical wound site, several hemostasis methods commonly used after surgery have certain disadvantages: 1. manual palm and finger pressing hemostasis, which is difficult to keep for a long time (0.5-5 hours) to realize continuous pressing hemostasis. 2. Sandbag compression hemostasis-the patient cannot keep a fixed posture; the gravity compression points of the sandbags are dispersed, and the compression hemostasis force is insufficient. 3. Bandage binding and compression hemostasis (shaped like a large tie of five flowers) -patient discomfort is obvious and individual patient is difficult to tolerate; the gauze bandage has no elasticity, and when the posture and the posture are changed, the bandage is naturally relaxed, the compression force is reduced, and the hemostasis is ineffective. 4. Re-surgical suture hemostasis-the chance of wound infection increases and adds additional pain to the patient. For the above reasons, there is a need for improvement.

Example 2:

in order to more clearly illustrate the special tourniquet, the embodiment is illustrated by taking compression hemostasis of a right neck surgical wound a of a human body as an example, the position of the right neck surgical wound a of the human body is shown in fig. 4, and fig. 5 shows a schematic diagram that after the right neck surgical wound a is surgically placed into the dialysis catheter D, the shape and position of the dialysis catheter D remaining outside the human body and the wound is wrapped with sterile gauze C.

Fig. 6 and 7 show the process of performing compression hemostasis on the right external neck surgical wound A by using the special tourniquet. Firstly, the fixing strap 1 is horizontally surrounded by armpits, and the thread gluing 103 at the two ends are adhered and fixed, so that the proper tightness of the fixing strap 1 is ensured. Then, a buckle 102 at a proper position on the fixing band 1 on the back of the patient is selected to be fixedly connected with a narrow backpack strip 202 at one end of a pressurizing band 2 in a penetrating manner, the pressurizing band 2 is stretched to enable an elastic band 201 to pass through a piece of sterile gauze C wrapped by the operation wound A on the outer side of the right neck, the narrow backpack strip 202 at the other end of the pressurizing band 2 is connected with the buckle 102 on the fixing band 1 on the front of the patient in a penetrating manner and is fixed after proper tightness is adjusted, and the compression hemostasis operation on the operation wound A on the outer side of the right neck is completed by utilizing the elastic force.

Example 3:

in order to more clearly illustrate the special tourniquet, the embodiment is illustrated by taking the compression hemostasis of the right inguinal operation wound B of the human body as an example, the position of the right inguinal operation wound B of the human body is shown in fig. 4, and fig. 5 shows that after the right inguinal operation wound B is implanted into the dialysis catheter D, the shape and the position of the dialysis catheter D outside the human body are retained, and the wound is wrapped by the sterile gauze C.

Fig. 8 and 9 show the process of performing compression hemostasis on the right inguinal operation wound B by using the special tourniquet. Firstly, the fixing strap 1 is used for encircling the waist, and the thread gluing 103 at the two ends of the fixing strap is bonded and fixed, so that the proper tightness of the fixing strap 1 is ensured. Then, a proper buckle 102 is selected on the fixing strap 1 on the back of the patient to be connected and fixed with a narrow backpack strap 202 at one end of the pressurizing strap 2 in a penetrating manner, the pressurizing strap 2 is stretched to the right side to be wound on the front of the patient, then the elastic strap 201 passes through the sterile gauze C bound by the operation wound B at the position of the right groin obliquely downwards inwards, then the sterile gauze C is wound around the thigh of the patient, the sterile gauze C bound by the operation wound B at the position of the right groin is further passed through the operation wound B at the position of the right groin obliquely upwards from the right outer side to the inner side of the thigh, namely the elastic strap 201 on the pressurizing strap 2 forms cross compression at the operation wound B at the position of the right groin, finally the narrow backpack strap 202 at the other end of the pressurizing strap 2 is connected with the buckle 102 on the front fixing strap 1 in.

Example 4:

the elastic cord 201 is of a double-layer structure, thread gluing which connects two layers of ports of the elastic cord 201 together is arranged at two ends of the elastic cord 201, an antibacterial coating is arranged between two layers of the elastic cord 201, when elastic force pressurization hemostasis is not carried out, any end thread gluing can be torn, and the elastic cord 201 is used as a bag for placing an external indwelling tube.

In order to prevent the displacement and the falling off of the indwelling tube, under most conditions, the indwelling tube has longer walking distance in vivo, the opening is kept nearby the armpit, the placing is not easy to fix, and the pollution is caused by sweating easily, so after hemodialysis and interventional surgery, the special tourniquet can be used for hemostasis, and the position can be adjusted to be used as a bag for accommodating the indwelling tube in vitro.

When not tightening and pressurizing hemostasis, the fastening binding positions of the narrow backpack strip 202 and the wide backpack strip 101 can be adjusted, the binding force is properly released, the position of the pressurizing strip 2 is adjusted, the elastic 201 moves down to the proper position, then the external indwelling tube is placed in an antibacterial bag formed by the double-layer structure of the elastic 201, and the falling of the catheter, the pollution and the like caused by shaking are avoided.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
