Closed care drainage device for cardiothoracic surgery

Abstract

The invention discloses a closed care drainage device for cardiothoracic surgery. The closed care drainage device comprises a drainage bag, the upper portion of the drainage bag is provided with a retractable part, one end of a drainage tube is connected with a puncture needle, the other end of the drainage tube is provided with a connecting sleeve, the top of the drainage bag is provided a sealing cover, the sealing cover is provided with a connecting hole connected with the connecting sleeve, and the connecting sleeve can be inserted into the connecting hole; a negative-pressure drainage apparatus is communicated with the drainage bag through a negative-pressure tube, the drainage tube is provided with a one-way valve, the one-way valve is formed by two one-way clacks arranged on the inner wall of the drainage tube, the one-way clacks point to the direction of drainage after being closed, the bottom of the drainage bag is provided with a liquid discharge tube, the liquid discharge tube is provided with a liquid discharge valve, and the drainage tube is provided with a squeeze tube located between the one-way valve and the drainage bag. Negative pressure is generated in the drainage bag through the negative-pressure drainage apparatus, and then effusion in the patient's body can be smoothly and thoroughly drained into the drainage bag under the action of negative pressure; asthe drainage tube is provided with the one-way valve, reverse flow of effusion can be prevented.

Description

technical field [0001] The invention relates to the technical field of negative pressure drainage appliances, in particular to a closed nursing drainage device for cardiothoracic surgery. Background technique [0002] At present, for patients with clinical cardiothoracic drainage, closed chest drainage is a commonly used treatment method in the field of cardiothoracic surgery. During treatment, the gas and liquid in the patient's chest should be discharged in time. Several drainage methods in the prior art There are certain deficiencies, one of which is to repeatedly suck the gas and liquid in the patient's thorax with a syringe. The disadvantage of this method is that the patient's thorax is repeatedly punctured, which increases the pain of the patient, and the labor intensity of the medical staff is high. Another method is thoracocentesis and drainage. The chest drainage tube widely used in clinical practice is medical silicone tube with end and side hole. , It is often n...

[0002] At present, for patients with clinical cardiothoracic drainage, closed chest drainage is a commonly used treatment method in the field of cardiothoracic surgery. During treatment, the gas and liquid in the patient's chest should be discharged in time. Several drainage methods in the prior art There are certain deficiencies, one of which is to repeatedly suck the gas and liquid in the patient's thorax with a syringe. The disadvantage of this method is that the patient's thorax is repeatedly punctured, which increases the pain of the patient, and the labor intensity of the medical staff is high. Another method is thoracocentesis and drainage. The chest drainage tube widely used in clinical practice is medical silicone tube with end and side hole. , It is often necessary to squeeze the drainage tube, but the squeezing effect of these drainage tubes is not good, it cannot produce a large pressure difference, and it cannot cause a strong flushing effect on the clots and cellulose that block the drainage tube. The external fixation effect of the patient is not ideal

[0003] The current negative pressure drainage device is composed of a drainage tube and a drainage bag, which has good negative pressure attraction and can avoid reflux infection, but the replacement of the drainage bag is more complicated and requires a lot of work intensity for the medical staff. The negative pressure device uses a ball The bladder needs to be squeezed to exhaust, which is cumbersome and troublesome to use

There is no anti-backflow device on the drainage tube. When the negative pressure ball is pressed, the drainage fluid in the drainage tube will easily flow back to the wound, resulting in poor drainage.
