AI Technical Summary

Technical Problem

The existing clinical puncture device of cardiovascular medicine is complicated to operate, has low aspiration efficiency, and is difficult to adapt to different treatment conditions, especially in emergencies such as acute cardiac pressure, which cannot meet the needs of rapid decompression.

Method used

A clinical puncture device for cardiovascular medicine is designed, and the first piston and the second piston move up and downward in synchronization with respect to the cylinder. By alternately generating pressure and negative pressure, rapid aspiration and discharge of pericardial effusion is achieved, which is suitable for different treatment situations.

Benefits of technology

It improves the aspiration efficiency and can quickly and effectively remove pericardial effusion. It is suitable for acute cardiac tumours, large amounts of exudative effusion, non-hematologic effusion removal, lavage and rinsing, etc., reducing the possibility of operating steps and misoperation.

Abstract

The present invention discloses a clinical puncture device for cardiovascular medicine, which relates to the field of medical devices and includes a flexible tube and a puncture needle installed at one end of the flexible tube. It further includes: a cylinder body, inside which a first piston and a second piston are slidably arranged along its axial direction. A first operating rod is installed on the upper surface of the first piston, and the top end of the first operating rod penetrates through the cylinder body and extends to the outside of the cylinder body. A second operating rod is installed on the upper surface of the second piston, and the top end of the second operating rod sequentially penetrates through the first piston and the first operating rod and extends to the outside of the cylinder body. By the synchronous up-and-down movement of the first piston and the second piston relative to the cylinder body, the present invention can efficiently aspirate pericardial effusion. This synchronous movement mode enables the upper cavity and the lower cavity to alternately generate pressure and negative pressure, realizing the rapid aspiration and discharge of pericardial effusion, and is applicable to various situations such as rapid decompression required for acute cardiac tamponade, a large amount of exudative effusion, non-bloody effusion clearance, lavage, and irrigation, greatly improving the aspiration efficiency.
