Magnetic peritoneal drainage tube device

Abstract

The invention discloses a magnetic peritoneal drainage tube device. The magnetic peritoneal drainage tube device comprises a drainage tube, an inner core arranged in the drainage tube and a magnetic controller arranged in vitro, wherein the inner core is magnetic, and the magnetic inner core enables the head end of the drainage tube to change the drainage position in vivo under the action of the magnetic controller; the magnetic inner core is provided with an air bag at the head end in vivo and is provided with an air extractor at the tail end in vitro, and the air extractor is communicated with an air guide tube arranged in the magnetic inner core. The magnetic peritoneal drainage tube device is simple in structure, can be used for accurately adjusting the head end of the drainage tube according to the specific drainage position after the drainage tube enters a body, and provides reliable guarantee for smooth drainage.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drainage tube. Background technique [0002] Drainage tubes used for abdominal cavity and pleural effusion drainage may be displaced due to patient turning over, body position changes, etc., and even poor drainage may occur. . Chinese patent 201410523458.5 discloses a drainage tube set, including a drainage tube and a rigid inner sleeve. The front end of the drainage tube and the tube wall behind the front end are provided with adsorbents that adsorb each other. When the rigid inner sleeve is inserted into the drainage When the drainage tube is in the tube, the drainage tube is stretched into a straight tube; after the drainage tube is implanted in the body and the rigid inner sleeve is withdrawn, the two adsorbents are adsorbed together, and the front end of the drainage tube is ring-shaped, realizing the function of fixing. However, this kind of fixing method can on...

Problems solved by technology

However, this kind of fixing method can only be carried out by relying on the operating experience of medical staff, and because the inner cannula is a rigid structure, after the inner cannula is inserted into the body, the position of the head end of the drainage tube cannot be adjusted according to the situation in the body, so it is easy to cause drainage Unblocked, complicated by abdominal infection and other diseases, and patients with anastomotic leakage may even need a second operation, which increases the pain of the patient
