Tricavity internal fixing type thoracic drainage tube and disposable thoracic closed type drainage device

Abstract

An expendable sealed thoracic drainage device is composed of an internally fixed three-cavity intrathoracic drain, hard puncture needle and drainage bag. Said intrathoracic drain consists of drain, water bag, water-injecting tube and medicine-injecting tube. Said rain has a three-cavity structure, that is, a water injecting cavity and a medicine injecting cavity are arranged in its tube wall.

Description

technical field [0001] The invention relates to a closed chest drainage device. Background technique [0002] The chest cavity closed drainage tube that adopts more at present is a silicone tube with a side hole at the front end, and a water-sealed bottle is connected at its rear end. The shortcoming of this closed drainage tube in application is that the drainage tube only has a simple drainage function. If drug injection is required, the wall of the drainage tube needs to be punctured with a syringe, and the drug is injected into the drainage tube and enters the chest cavity through the drainage tube. The needle hole of the punctured tube wall will leak air, lose its airtightness, and cause pneumothorax; the length of the drainage tube inserted into the chest is completely determined by the doctor's experience, and it is difficult to guarantee the optimal length of 4-5 cm. If it is too long, the drainage tube will be easily discounted, which is not conducive to drainage. ...

AI Technical Summary

Problems solved by technology

The shortcoming of this closed drainage tube in application is that the drainage tube only has a simple drainage function. If drug injection is required, the wall of the drainage tube needs to be punctured with a syringe, and the drug is injected into the drainage tube and enters the chest cavity through the drainage tube. The needle hole of the punctured tube wall will leak air, lose its airtightness, and cause pneumothorax; the length of the drainage tube inserted into the chest is completely determined by the doctor's experience, and it is difficult to guarantee the optimal length of 4-5cm

If it is too long, the drainage tube will be easily discounted, which is not conducive to drainage. If it is too short, it will not only be not conducive to drainage, but also may cause pneumothorax or subcutaneous emphysema if the side hole enters the chest wall

Therefore, it is often necessary to repeatedly adjust the position of the drainage tube according to the chest X-ray or chest X-ray. Every time the tube is adjusted, the original fixing line must be removed, and then fixed with local anesthesia. Both require the use of sterile suture kits, which is very troublesome

At the same time, the drainage bottle, silicone tube and aseptic incision and suture kit of the drainage tube are separated, and it is quite difficult for one person to operate, which is not conducive to on-site rescue and is also not conducive to the transfer of the wounded by ambulance
