Description

Effusion discharging device for tumor nursing Technical Field The invention belongs to the technical field of medical appliances, and particularly relates to a effusion discharging device for tumor nursing. Background In the clinical treatment and care of malignant tumors, patients often have symptoms such as pleural effusion and peritoneal effusion due to invasion of tumor cells into the pleural, peritoneal or lymphatic system. In order to relieve the compression of effusion on viscera and improve the respiratory and circulatory functions of patients, an effusion discharge device (such as a negative pressure drainage device) is generally used for continuously draining and collecting the internal effusion in clinic. The existing effusion discharging device for tumor nursing mainly comprises a drainage catheter, a negative pressure generating source, a liquid storage container (such as a liquid collecting bottle or a drainage bag) and other basic components, and the effusion in a body cavity is directionally guided into the liquid storage container outside the body by maintaining the negative pressure environment in a pipeline. However, in practical clinical care applications, the existing effusion discharge devices have the following technical drawbacks: First, clinical drainage procedures are generally continuous and long lasting. During a long drainage period, the condition of the patient is often in dynamic change. When a patient has sudden physical sign changes (such as severe pain, abnormal fluctuation of blood pressure or suspected internal hemorrhage and other adverse reactions), medical staff is urgent to sample the effusion discharged by the specific time node accurately in real time so as to detect physicochemical properties, cytological components, blood content or tumor marker concentration, thereby being used as a key diagnosis basis for evaluating the current drainage effect and the disease progress. However, the existing drainage device adopts a single terminal liquid collecting container, and liquid products discharged in different time periods can be mixed after entering the liquid storage bottle, so that medical staff cannot separate and extract liquid product samples at a certain specific moment from the mixed liquid at all, and timeliness and accuracy are lost in real-time pathology detection. Secondly, in order to overcome the defect that the sample cannot be taken in real time, the current clinical compromises are usually forced aspiration sampling by directly puncturing the drainage pipeline with a syringe needle. From the perspective of hydrodynamics and medical instrument safety, the operation has the great hidden trouble that the puncture behavior can destroy the stability of the whole drainage system, and the puncture behavior can cause severe fluctuation of fluid in a pipeline at the suction moment, so that the original negative pressure unbalance and pressure disturbance of the system are caused, the subsequent normal drainage is influenced, the turbulence and even the effusion backflow of the fluid in the pipeline are extremely easy to be caused by the external suction negative pressure, and the clinical risk of retrograde infection is greatly increased. Disclosure of Invention According to the effusion discharging device for tumor nursing, the pluggable sample exchanging support component is arranged between the discharging pipe and the discharging pipe, when the component is pushed in, the sampling pipe is communicated with the main path to realize rapid liquid discharging, when the component is pulled out, the magnetic positioning and resetting mechanism is used for linkage, the step sliding block is pushed to automatically close the main path before the sampling pipe is separated, real-time accurate sampling of effusion is realized, negative pressure is maintained stably in the whole process, leakage is avoided, meanwhile, the pre-charging heparin is effectively prevented from being blocked, and the operation is rapid and simple. The technical scheme includes that the effusion discharging device for tumor nursing comprises a vertically fixed mounting plate, support plates are horizontally and symmetrically arranged at two ends of the mounting plate, first L-shaped clamping grooves are symmetrically formed in the edge of the inner side of each support plate along the length direction, and a discharging pipe which are coaxially arranged are respectively communicated with each other up and down. Further, the novel sliding mechanism further comprises two first ladder sliding blocks which are symmetrically arranged, each first ladder sliding block horizontally clings to and slides in a slideway formed by each group of first L-shaped clamping grooves, and a connecting rod is connected between the two first ladder sliding blocks. Further, a first reset mechanism and a limiting and positioning mechanism are respectively arranged in the middle of the mounting plate towards the conne
