Catheter flushing system for implantable intravenous infusion port

Abstract

The invention relates to the technical field of medical equipment, in particular to a catheter flushing system for an implantable venous port, which comprises a main body, an auxiliary body is arranged on one side of the main body, an operating mechanism is mounted on the main body, a butt joint mechanism and a pressure relief mechanism are arranged at one end of the main body, and a pulse mechanism and a quantification mechanism are arranged in the auxiliary body. The quantifying mechanism limits the pulse mechanism, and a synchronizing mechanism is connected between the pulse mechanism and the operating mechanism; through the butt joint mechanism, the main body and the guide pipe can be quickly disassembled and connected, and the operation efficiency is improved; through the arrangement of the pressure relief mechanism, the effect of pressure overload protection can be achieved, and the situation that the pressure for injection is too large is avoided; by means of the pulse mechanism, the effect similar to pulse is achieved when injection is executed, and the catheter is effectively flushed; quantitative injection can be conveniently achieved through the quantitative mechanism, accurate medication is achieved, and the use safety of the device is improved; pulse and normal injection modes can be conveniently switched according to actual use requirements through the synchronizing mechanism, and operation is more flexible and efficient.

Description

Technical field [0001] The present invention relates to the technical field of medical equipment, specifically a catheter irrigation system for implantable intravenous infusion ports. Background [0002] An infusion port is an infusion device that is buried inside the human body and provides patients with long-term intravenous vascular access. Infusion ports are generally surgically buried under the patient's skin; The infusion port is mainly used for patients who need long-term chemotherapy, repeated blood draws, repeated blood transfusions and long-term intravenous nutrition, and the design of the infusion port has a long service life, from more than five years to twenty years or even lifelong use, and the catheter needs to be flushed and maintained when using the infusion port. [0003] However, when the infusion port is maintained, the traditional enlargement basically adopts the manual method, using the syringe manual interval injection method to simulate pulse flushing, b...

Problems solved by technology

[0003] However, when maintaining the infusion port, the traditional enlargement is basically done manually, using a syringe to simulate pulse flushing by manual interval injection. Since flushing clearly prohibits strong flushing and high-pressure injection, but the experience level of each operator is uneven, This puts forward high requirements for professionalism, increases the operational difficulty of using the infusion port, and is not convenient for medical staff who have just stepped into the workplace. Therefore, it is urgent to propose a kind of implantable venous infusion port. catheter flushing system
