Disposable sterile multi-serous cavity effusion drainage device

Abstract

The invention discloses a disposable sterile multi-serous cavity effusion drainage device. The device comprises a skin expander and a built-in tube, wherein the skin expander is a bullet-shaped cylinder; a conical tip with external threads is arranged on the lower portion of the cylinder; an axial breaking seam is formed in the peripheral wall of the conical tip and breaks the wall of the conicaltip; the built-in tube is arranged in an inner cavity of the skin expander in a sliding mode; and the lower end of the built-in tube is located on the lower portion of an inner cavity of the conical tip. The drainage device has the beneficial technical effects of being simple in structure, convenient to operate and capable of enabling effusion in the organ of a patient to enter an effusion tank through the built-in tube and a drainage tube, and has the characteristics of shortening the drainage treatment operation time, relieving pain of the patient, improving the operation efficiency of medical staffs and reducing the cost.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable aseptic multi-serosa cavity effusion drainage device. Background technique [0002] In the process of clinical diagnosis and treatment, patients with pericardial effusion, pleural effusion and peritoneal effusion often need emergency drainage. Closed chest drainage is conducive to gas discharge and improves patient symptoms. The current operation method of closed thoracic drainage fluid is to select the puncture site, use a longer puncture needle to carry the guide wire to penetrate the subcutaneous tissue, muscle and parietal pleura in sequence to reach the pleural cavity, and then use a skin expander to expand the subcutaneous tissue. Then take a disposable soft plastic tube as a drainage tube and put it into the pleural cavity along the guide wire, and connect the closed drainage bag at the end. In the prior art, although the disposable aseptic indwelling...

AI Technical Summary

Problems solved by technology

In the prior art, although the disposable aseptic indwelling drainage catheter device approved for clinical use can be used for emergency treatment, there are the following problems in use: the skin expander of the original drainage device has poor penetrability, and the drainage tube is inserted into the patient. Organ operation takes a long time, puncture efficiency is low, and patients suffer for a long time
