AI Technical Summary

Technical Problem

Traditional pleural effusion drainage methods need to be operated in medical institutions, which have problems with infection risk and protein loss, which affects the patient's rehabilitation process and increases medical costs.

Method used

A pleural fluid autologous drainage device is designed to form a pipe through the connection of the thoracic and abdominal perforation catheter, and the intermediate catheter is used to introduce the pleural fluid into the abdominal cavity. Anti-counterflux structure and power module are set up to control the drainage speed and reduce the risk of protein loss and infection.

Benefits of technology

Effectively reduce protein loss, reduce infection risk, promote patient rehabilitation, reduce hospitalization time and treatment costs, and improve quality of life.

Abstract

The invention discloses a hydrothorax autologous drainage device which comprises a thoracentesis catheter and an abdominal puncture catheter. The thoracic puncture catheter and the abdominal puncture catheter are communicated and connected through a middle catheter to form a pipeline capable of guiding hydrothorax from the chest cavity to the abdominal cavity, an anti-backflow structure is arranged on the pipeline, and a power module can be further arranged on the middle catheter to change the drainage speed. The pleural effusion is led to the abdominal cavity from the thoracic cavity, so that protein loss can be avoided while the pleural effusion is reduced; due to the portability of the equipment, the equipment can be carried and used outside a hospital for a long time, the out-of-hospital survival time of a patient is prolonged, and the living quality is improved.
