Problems solved by technology

On the one hand, the incidence of thrombosis in the double-lumen central venous catheter in maintenance hemodialysis patients is still high; on the other hand, when the blood coagulation phenomenon is solved, the catheter is not easy to unblock, resulting in the need to replace a new catheter , not only brings pain to patients, but also increases the economic burden of patients

Embodiment 1

[0039] like Figure 1 to Figure 11 As shown, a central venous catheter locking pump includes a first pump body 100, a second pump body 101, and a flow diversion unit 102. The first pump body 100 includes a casing 1, and the casing 1 is provided with a housing cavity 2, the shell 1 is provided with a connecting ring 3, the connecting ring 3 is located at the opening of the containing cavity 2 and coincides with the center line of the containing cavity 2, the detachable A positioning shield 5 is provided, and the upper end of the positioning shield 5 is provided with an opening 6;

[0040]A syringe 7 is arranged in the accommodating chamber 2, and the head of the syringe 7 extends out of the accommodating chamber 2 and is located in the positioning shield 5; injection pump, the first pump body 100 has the same structure as the second pump body 101;

[0041] The distribution unit 102 includes a distribution box 103, the inside of the distribution box 103 is provided with a part...

Embodiment 2

[0060] This embodiment is further optimized on the basis of Embodiment 1. This embodiment is basically the same as Embodiment 1, the difference is that only the first pump body 100 is provided in this embodiment (such as Figure 12 As shown), the second pump body is not provided, and two accommodation chambers are arranged in the first pump body 100, each accommodation chamber is respectively provided with a syringe for installing medicine, and each syringe is respectively passed through each connecting tube 107 It is connected with the arterial tube 21 and the venous tube 22. In this embodiment, the first pump body 100 simultaneously controls the two syringes so as to realize the injection of the drug. Since the pump body is carried outside the human body, two pump bodies are optimized into one pump body in this embodiment, which reduces the number of pump bodies and makes it more convenient to carry.

Abstract

The invention discloses a central venous catheter sealing pump. The central venous catheter sealing pump comprises a shell; a containing cavity is formed in the shell; a connecting ring is arranged onthe shell; the connecting ring is located at an opening of the containing cavity and coincides with the center line of the containing cavity; a positioning protective cover is detachably arranged onthe connecting ring; an opening is formed in the upper end of the positioning protective cover; an injector is arranged in the containing cavity; the head of the injector extends out of the containingcavity and is located in the positioning protective cover; and an injection pump used in cooperation with the injector is arranged in the shell. According to the invention, on one hand, the thrombusoccurrence rate of a double-cavity central venous catheter of a hemodialysis patient is effectively reduced; and on the other hand, the situation that a new catheter needs to be replaced due to the hemagglutination phenomenon is avoided, and the economic burden of the patient is reduced while the pain of the patient is relieved. The central venous catheter sealing pump has the beneficial effects of simple structure, convenience in operation, difficulty in damage, low manufacturing cost and the like.

Description

technical field [0001] The present invention relates to a tube sealing pump, in particular to a central venous catheter sealing pump and its use method. Background technique [0002] When the patient is undergoing dialysis, the catheter needs to be sealed with heparin sodium after each dialysis. About 48 hours later, you need to do hemodialysis again. During this time, blood clots are prone to occur in the catheter. When hemodialysis is performed again, hemolytic drugs need to be injected first, and hemodialysis can only be performed again after the hemodialysis is completed. On the one hand, the incidence of thrombosis in the double-lumen central venous catheter in maintenance hemodialysis patients is still high; on the other hand, when the blood coagulation phenomenon is solved, the catheter is not easy to unblock, resulting in the need to replace a new catheter , not only bring suffering to patients, but also increase the financial burden on patients. [0003] Therefo...
