Need to use At least five different syringes and needles waste medical resources and increase the burden of medical expenses for patients; 3. Repeated insertion and extraction waste time.

Utility model content

The utility model is to solve the problem that in the existing hemodialysis, at least five different syringes and needles need to be used, and different syringes connected to the central venous catheter are repeatedly inserted and pulled out, which may easily cause blood infection of the central venous catheter, and then lead to fever and bacterial blood in the patient. It is easy to cause the problem of air embolism caused by air entering the central venous catheter, and provides a central venous catheter thrombolysis device for hemodialysis.

The technical scheme that the utility model adopts for solving the above problems is:

A central venous catheter thrombolysis device for hemodialysis, which consists of a suction tube, a flow inspection tube, a saline through tube, a drug injection tube, a suction syringe, a flow syringe, a saline syringe, a urine enzyme syringe, a connecting tube and a stopper. flow valve, the output ends of the suction pipe, the flow inspection pipe, the brine pipe and the drug injection pipe are all communicated with the connecting pipe, the input end of the liquid suction pipe is connected with the liquid suction syringe, and the input end of the flow inspection pipe The end is connected with the flow injector, the input end of the saline pipe is connected with the saline syringe, the input end of the injection pipe is connected with the urine enzyme syringe, the suction pipe, the flow inspection pipe, the saline pipe and the medicine injection Stop valves are installed on the pipes.

Further, the saline syringe is a one-way syringe.

The utility model has the following beneficial effects:

1. There is no need to insert and pull out the syringe repeatedly. The utility model can be used for one-time insertion until the end of thrombolysis and then pulled out. It complies with the principle of sterility and can prevent the risk of central venous catheter infection and air thrombolysis caused by multiple syringes.

2. Save medical resources, do not need several syringes, and reduce the economic burden of patients.

3. There is no need to insert and pull out the syringe repeatedly, which saves the treatment time of doctors, nurses and patients, and is more suitable for patients who undergo hemodialysis treatment as soon as possible after emergency thrombolysis.
