Urinary catheter with anti-blocking function

Abstract

The invention provides a ureter with an anti-blocking function, belongs to the technical field of medical instruments, and aims to solve the problem that normal drainage is affected due to the fact that an existing ureter is easy to block when facing urine containing blood and flocculate. Comprising an anti-blocking cavity and a urination cavity which are isolated, and an anti-blocking pipe and a urination pipe are correspondingly arranged at the tail end of the catheter body; the head end of the pipe body is connected to one side of the main end, the auxiliary end is connected to the other side of the main end through a telescopic structure, the telescopic structure is communicated with the anti-blocking cavity and the anti-blocking pipe, and the telescopic amount of the telescopic structure is adjusted through fluid. Through meshes are formed in the opposite end faces of the main end and the auxiliary end and located on one side of the main end, the urination cavities outside the main end and inside the main end are communicated through the through meshes, a protruding cone array is arranged on one side of the auxiliary end, and when the telescopic structure controls the auxiliary end to be close to the main end, the protruding cone array can be inserted into the through meshes. The method has the technical effects that the blockage risk is greatly reduced, and dredging treatment after blockage is simple and convenient.
