Description

Bidirectional interchangeable connector capable of realizing liquid circulation Technical Field The invention relates to the technical field of medical auxiliary instruments, in particular to a bidirectional interchangeable connector capable of realizing liquid circulation. Background The device is suitable for body cavity circulation perfusion treatment, the treatment means is commonly used for clinical treatment of abdominal cavity, thoracic cavity and other parts, and the treatment purpose is realized by means of continuous and stable liquid circulation. In the prior art, the liquid circulation connector mostly adopts a fixed one-inlet one-outlet passage structure, and the main joint of the liquid circulation connector is directly connected with a body cavity of a patient, so that the liquid circulation connector is easily blocked by falling tissues brought out by circulating fluid. Once the main joint is blocked, medical staff needs to detach the pipeline for reconnection, and the operation can directly interrupt perfusion treatment, reduce the treatment effect, and also can introduce external pollution due to pipeline disassembly and assembly, so that clinical potential safety hazards exist. At present, the traditional connector lacks the design that can switch the circulation path fast without dismantling, can not maintain the treatment continuity when the jam occurs, and is difficult to satisfy the clinical high-efficient and safe treatment needs. Disclosure of Invention The invention aims to at least solve one of the technical problems in the prior art, provide a bidirectional interchangeable connector capable of realizing liquid circulation, solve the problem that a fixed passage of a traditional body cavity perfusion connector is easy to cause interruption of treatment and pollution introduction due to blockage of a main joint, and realize disassembly-free rapid reversing. The invention further provides the bidirectional interchangeable connector capable of realizing liquid circulation, which comprises two guide pipes which extend along the same direction and are parallel to each other, wherein the two ends of each guide pipe are respectively communicated with one first connector and one second connector, the side surface of each first connector is communicated with two main joints, the main joint on one guide pipe is an inlet body, the main joint on the other guide pipe is an outlet body in the process of body cavity circulation perfusion treatment, the two side surfaces of the connector corresponding to one guide pipe are communicated with inlet joints, the two side surfaces of the connector corresponding to the other guide pipe are communicated with outlet joints, and a reversing assembly is arranged between the two guide pipes and is used for switching the circulation paths of liquid in the two guide pipes when any main joint is blocked so as to maintain the continuity of liquid circulation. Preferably, the reversing assembly comprises two reversing pipes, wherein the two reversing pipes are arranged in a crossing mode, two ends of the reversing pipes are respectively communicated with the corresponding first connector and the corresponding second connector to form a parallel fluid passage, one side of each of the two first connectors is communicated with an auxiliary joint, and the auxiliary joint is communicated with the reversing pipe when any main joint is blocked. Preferably, the reversing assembly further comprises a pipe clamp assembly, wherein the pipe clamp assembly comprises two shells, and the two shells are respectively sleeved on the outer walls of the two reversing pipes. Preferably, the pipe clamp assembly further comprises a screw and a clamping plate, wherein the clamping plate is connected to the inner wall of the shell in a sliding manner and is abutted against the corresponding reversing pipe, the screw is connected to the rear surface of the clamping plate in a rotating manner, and the other end of the screw is connected to the outside of the shell in a threaded manner. Preferably, an elastic sealing gasket is arranged on one side of the clamping plate, which faces the reversing pipe, and is used for sealing and plugging the reversing pipe when the clamping plate abuts against the reversing pipe. The beneficial effects are that: According to the bidirectional interchangeable connector capable of realizing liquid circulation, when the main joint of the outlet catheter is blocked by falling tissues, a pipeline is not required to be detached or treatment is not required to be interrupted, and a reversing pipe passage can be opened only by operating the reversing assembly, so that fluid forms a new circulation path through the auxiliary joint and the reversing pipe, the pouring direction is rapidly switched, the original outlet is changed into the inlet, the inlet is changed into the outlet, the circulation interruption and treatment stagnation caused by the pipeline blockage
