Abstract

The invention relates to the technical field of drainage catheters, in particular to an embedded chest drainage catheter. The chest drainage catheter comprises a drainage catheter and a butterfly-shaped adhesive plaster installed on the surface of the drainage catheter. A plurality of projections are disposed nearby one end of the drainage catheter, and one side, close to the adhesive tape, of a connection part is provided with a plurality of clamping grooves. According to the chest drainage catheter, the projections of the drainage catheter are clamped in the slots of the butterfly-shaped adhesive plaster, and then the butterfly-shaped adhesive plaster is pasted on skin, thereby solving a problem that a patient needs to be painful because a conventional catheter can be fixed under the condition of one-needle seaming on the skin after placement. Meanwhile, when the catheter is pulled out, the drainage catheter can be directly pulled out, and can avoid the damages to the tissues like asingle-J catheter and even avoid the scratch on the artery.

Description

technical field [0001] The invention relates to the technical field of drainage catheters, in particular to chimeric chest drainage catheters. Background technique [0002] Closed chest drainage is to put one end of the drainage tube into the chest cavity, and the other end is connected to a water-sealed bottle lower than its position, so as to expel air or collect fluid in the chest cavity, allowing the lung tissue to reopen and restore function. As a treatment method, it is widely used in the drainage of hemothorax, pneumothorax, empyema and after thoracotomy, and plays a very important role in the treatment of diseases. [0003] After the traditional catheter is placed, a needle needs to be sutured on the skin for fixation, which makes the patient suffer from pain again. The single-J catheter avoids the pain of skin suturing after catheterization, and replaces it with a built-in silk thread to curl the front end of the catheter into a snail shape, avoiding slippage. How...
