Embodiment 1

[0016] Adjust to drainage state. Clamp the end of the drainage tube, connect the drainage bottle, push the built-in sleeve 5 of the rear section 3 of the drainage tube with the assistance of the booster protrusion 6, so that it moves forward to the middle section 2, and supports the closed middle section 2 , Open drainage, if necessary, the drainage bottle can be connected to a negative pressure device to speed up the drainage, so that the drainage is more sufficient.

Embodiment 2

[0018] Adjust to a painless / non-draining state. After sufficient drainage, open the side hole plug 11, withdraw the traction sheath 5 to the back section, close the side hole 8, clamp the drainage tube, remove the drainage bottle, and after the end plug 9 is sterilized, close the end and fix the drainage tube. After the cannula 5 is withdrawn, the middle section 2 is closed under the extrusion action of structures such as the thoracic and abdominal walls.

Embodiment 3

[0020] Fixed after intubation. After the operation, the drainage tube is placed according to the condition, and after being properly fixed with the fixing band 10, the drainage tube is adjusted to a painless or drainage state as the case may be.

Abstract

The invention discloses a painless adjustable intermittent drainage tube. The drainage tube adopts the design of 'front section hard material-middle section soft material-back section hard material and a movable sleeve tube built in the drainage tube' is adopted, the tube body is provided with metal wire strips or wire strips containing metal, two structure layers are arranged on the back section,an internal layer structure is the movable sleeve tube, a side hole and a side hole plug are arranged on the outer layer of the back section, and a tail end plug is arranged at the tail end. The drainage tube main body organically composed of three-section structures and a fixing band achieve adjustable intermittent painless drainage. The drainage tube achieves the intermittent drainage of pneumatosis and hydrops in the body cavity through the adjustable structure, and continuous pain and potential adverse influences which are caused by continuous extrusion conducted on the thoracoabdominal wall and other body structures by a traditional drainage tube body are avoided.

Description

technical field [0001] The invention relates to a medical drainage device, in particular to a drainage tube. Background technique [0002] Chest drainage tubes, some abdominal cavity drainage tubes, and body surface drainage tubes, which are widely used at present, are usually rigid tubular plastic products of uniform thickness, and can be divided into different models according to different inner diameters and shapes. Taking the chest drainage tube as an example, its working principle is to continuously drain the abnormal gas and liquid generated in the pleural cavity through the lumen of the drainage tube. For example, the Chinese invention patent with the notification number CN105131800A discloses "a medical painless chest drainage tube", which performs drainage through the lumen of the drainage tube, and achieves pain control by injecting analgesic drugs into the membranous drug sac structure. This kind of continuous chest drainage that relies on its own hardness suppor...
