Abstract

The invention discloses a disposable thrombus filter connector. The disposable thrombus filter connector comprises a first connector body, a rotary piston and a second connector body which are communicated. The rotary piston comprises a sliding groove, a piston piece, a handle and a hollow cylindrical outer shell, wherein the sliding groove is formed in the lateral surface of the outer shell, the piston piece is arranged in the outer shell, the handle is arranged outside the outer shell, the piston piece and the handle are connected, and the handle drives the piston piece to rotate through the sliding groove. The disposable thrombus filter connector prevents formed thrombus from falling into blood and causing serious complications, is convenient and practical, avoids the waste of extracted blood of a patient in operation (usually 5-10 ml of the blood of the patient is abandoned due to the worries of micro thrombus), then pulse type tube flushing is carried out to guarantee the smoothness of a retain tube, and the maintenance time is longer.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a disposable thrombus filter joint. Background technique [0002] Deep vein catheterization is currently being used more and more widely, especially in parenteral nutrition in surgery and intravenous infusion therapy for chronic diseases (malignant tumors). The indwelling tube of deep vein catheterization is buried for a long time, and generally can be kept for 3-6 months, but in this way, the patient faces the risk of venous thrombosis in the lumen. [0003] At present, our traditional dredging method requires multiple syringes for dredging, and each dredging requires about 3 to 4 syringes, and the blood we draw and the syringes we use will waste about 5 ml of blood. It is well known that our tumors Blood is very precious for patients, especially those with advanced tumors. Disadvantages of usual dredging methods: 1), waste of medical resources; 2), waste o...
