Puncture drainage combined bag

Abstract

The invention relates to a puncture drainage combined bag. The puncture drainage combined bag comprises a drainage device, a drainage bag, a heparin cap, a crossover coupling, a puncture needle, an expander and a guide wire, wherein universal first inner threads are arranged at one end of the heparin cap; the drainage device consists of a drainage sheath, a first joint and a second joint; first outer threads which are connected with the first inner threads are separately arranged at the outer end of the first joint and the outer end of the second joint; first inner threads are arranged at oneend of the crossover coupling; second outer threads are arranged at the other end of the crossover coupling; the drainage bag is provided with a circulating tube; and second inner threads which are matched with the second outer threads are arranged at the tail end of the circulating tube. According to the puncture drainage combined bag, threaded connection of the circulating tube on the drainage bag can be realized by the crossover coupling, firm connection between the drainage bag and the drainage device is ensured, an existing mode of connecting a drainage bag with a drainage tube through ashort tube joint and adhesive tapes is changed, the circumstance that the drainage bag is separated from the drainage tube when the overturning or action amplitude of a patient is over large is avoided, the beneficial effect is remarkable, and the puncture drainage combined bag is suitable for being applied and popularized.

Description

technical field [0001] The present invention relates to a puncture and drainage combination bag, and more specifically relates to a puncture and drainage combination bag suitable for pericardial puncture, thoracentesis and drainage. Background technique [0002] Clinically, it is necessary to drain the effusion in a specific part of the human body, such as pericardiocentesis, thoracentesis, etc. After the puncture, a drainage sheath is inserted, and a drainage bag is connected to the end of the drainage sheath, so that the effusion in the patient’s body can be drained to the Inside the drainage bag. However, there is currently no device specially used for pericardiocentesis, thoracentesis and drainage, but a traditional central venous catheter package is used instead; since the central venous catheter does not need to lead out body fluids, there is no drainage device in the central venous catheter package. After the deep vein catheter is inserted into the human body, it is ...

AI Technical Summary

Problems solved by technology

However, due to the adhesive tape connection, the connection between the joint of the deep vein catheter and the drainage bag is not firm. When the patient turns over or has a large range of motion, the connection between the deep vein catheter and the drainage bag will be disconnected, which will lead to deep vein drainage. The venous tube communicates with the outside world and the effusion flows out, which seriously affects the normal treatment and the safety of the patient. At the same time, the drained liquid contaminates the sheets, bedding, etc.
