Abstract

The invention provide a leaf-proof free-mounted pearls shape drainage tube, which is mainly used to breast vomica conduction after the operation of breat cancer and other coelom conduction. It comprises tube and bursa as a whole, and made from silica gel or rubber. The bursa comprises an imperforate bursa body and another bursa body with holes. The full length of drainage tube is 40 cm while the first imperforate 20 cm is out of body and the left 20 cm with holes is shaped strings of pearls and in the body. In the drainage tube, every 5 cm is mounted a pearls shaped expanded bursa with holes on the wall. The middle of tube is a ball shape imperforate bursa while the thickness of tube wall and bursa wall is 1-3 mm, which solve the problems of easy leak and demand for mounted, also increase the area of drainage hole by the ball shaped bursa, in particular having significantly effect on the preventing leak and block when suck the drainage tube in negative pressure. It can reduce the suffering of patients and related complications.

Description

technical field

[0001] It is mainly used in the medical field for female breast cancer surgery and breast abscess drainage. The principle of this technology can also be extended to especially the drainage that is suctioned by negative pressure, such as gastrointestinal decompression drainage, chest drainage, abdominal drainage and thyroid drainage. Drainage after surgery, etc. Background technique

[0002] At present, the widely used traditional female breast cancer surgery and breast abscess drainage often use ordinary rubber tube drainage, which is prone to leakage, needs to be fixed, and is inconvenient to use. It needs to be processed by cutting holes on the tube. When negative pressure is applied to the drainage tube, the lumen becomes flat, so drainage leakage is easy to occur, which brings great inconvenience to patients and clinicians, and may also cause infection. Contents of the invention

[0003] In order to overcome the problems of troublesome fixation and eas...
