Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a clinical puncture device for cardiovascular medicine. Background Art

[0002] Pericardiocentesis is a diagnostic and treatment technique that uses a puncture needle to directly puncture the pericardial cavity. Pericardiocentesis must be performed under sterile techniques, with local application of procaine anesthesia. The puncture site should not be too deep to avoid puncturing the atrium, ventricle or coronary artery, causing a large amount of blood accumulation in the pericardial cavity. Patients undergoing pericardiocentesis can understand the nature of the pericardial effusion by testing the fluid in the pericardial cavity, and identify the cause of pericarditis based on the nature of the pericardial effusion.

[0003] Existing devices are unable to continuously discharge the retained effusion, and repeated extraction and drainage require repeated needle insertion and removal. Patients experience the pain of multiple punctures, the treatment efficiency is low, and it is impossible to combine extraction and injection of therapeutic agents into one. The operations of extracting effusion and administering drugs are cumbersome. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides: a clinical puncture device for cardiovascular medicine, specifically comprising:

[0007] The puncture device comprises:

[0008] A syringe, the syringe having a barrel and a piston arranged inside the syringe, the top of the piston passes through the syringe and is fixedly connected to a pressing plate, the bottom of the syringe is connected to a puncture needle through a first control valve, and the syringe is arranged inside a fixed sleeve;

[0009] A liquid extraction tube, the liquid extraction tube having a tube body and a liquid storage cylinder arranged at one end of the liquid extraction tube, the liquid storage cylinder being arranged at the bottom of the fixed plate, and the end of the liquid extraction tube away from the liquid storage cylinder being connected to the injection cylinder through a second control valve;

[0010] A medicine storage tank, which has a tank body and a heating device arranged inside the medicine storage tank. The interior of the medicine storage tank is connected to a medicine outlet pipe, and the end of the medicine outlet pipe away from the medicine storage tank is connected to the injection barrel through a third control valve. When the patient needs to be injected with medicine, the accumulated fluid in the injection barrel is completely discharged, the first control valve and the second control valve are closed, and the third control valve is opened to connect the medicine storage tank with the injection barrel. At this time, the pressing plate is pulled to draw the medicine inside the medicine storage tank into the injection barrel, and then the third control valve is closed and the first control valve is opened to inject the medicine in the injection barrel into the patient's body. The extraction of liquid and the injection of therapeutic agents can be combined into one, making the operation of extracting accumulated fluid and administering medicine more convenient, while reducing the pain of repeated injections for patients.

[0011] After opening the first control valve, the pressing plate is pulled to drive the piston to move upward, and the accumulated fluid is driven from the puncture needle into the injection barrel. The accumulated fluid in the injection barrel increases continuously, and the first control valve is closed to open the second control valve. At this time, the injection barrel is connected to the liquid storage barrel, and the pressing plate is pushed to drive the piston to move downward, and the accumulated fluid in the injection barrel is pressed into the liquid storage barrel until the accumulated fluid in the injection barrel is completely discharged. If it is necessary to draw fluid again, the second control valve can be closed and the first control valve can be opened again to draw fluid. The retained accumulated fluid can be continuously discharged, and the drawing and draining can be repeated without repeated needle insertion and removal, thereby reducing the pain of multiple punctures for patients and increasing the efficiency of treatment.
