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 on

Embodiment Construction

[0017] The drainage tube 20 is a three-chamber type. The drainage chamber 3 plays a drainage role, and the drug injection chamber 6 and the water injection chamber 12 are both located in the tube wall. The front port 13 of the water injection chamber communicates with the water bag 5 , and the rear port 14 is connected to the auxiliary water injection pipe 11 , and the auxiliary water injection pipe 11 has a one-way valve 10 . A one-way flap 9 is arranged in the one-way valve 10 . The front port 4 of the injection cavity is located at the front port 1 of the drainage tube, and the rear port 15 is connected to the medicine injection auxiliary pipe 7, and the medicine injection auxiliary pipe 7 has a one-way valve 8. Water bag 5 is about 2cm long, next to side hole 2. The side hole 2 is about 2 cm away from the front port 1 of the drainage tube.

[0018] The drainage tube 20 is fixed in the chest by the water bag 5, and the length of the water bag is 2 cm. Therefore, the len...

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. ...
