Drainage device

Abstract

A drainage device comprises a drainage tube, and the drainage tube is provided with a drainage channel used for playing a drainage role and a shaping cavity channel used for containing a fluid medium; wherein the drainage channel penetrates through the drainage tube in the length direction of the drainage tube; the shaping cavity channel is arranged on the peripheral side of the drainage channel and extends in the length direction of the drainage tube; and the drainage tube can be in a firm state when the shaping cavity channel is filled with the fluid medium and keeps the fluid medium, and the drainage tube can be in a free state when the fluid medium is discharged out of the shaping cavity channel. By filling the fluid medium into the shaping cavity channel, the drainage tube which is soft and easy to bend originally becomes straight and is not easy to bend, so that not only can guarantee be provided for the tail end of the drainage tube to smoothly reach a specified operation area part and the convenience and the safety of operation and use be improved, but also the drainage tube with a proper length can be arranged as required, so that the drainage tube can stretch into a deeper human body through human body parts such as an oral cavity and an anus to execute operation items such as drainage, suction and flushing.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a drainage device. Background technique [0002] Drainage tube is a kind of medical equipment that is widely used in clinical surgery. In minimally invasive surgery such as laparoscopic surgery or other open operations, drainage tube is usually used to suction or flush the operation area, such as using The drainage tube sucks and removes blood, tissue fluid, pus, flushing fluid, exudate and other substances that affect the operation process in the operation area, or injects sterile physiological saline into the operation area with the help of the drainage tube, so as to remove the contamination of the operation area. objects or instruments for flushing.

Problems solved by technology

[0003] At present, the tube body (or tube body) of the suction and drainage tubes, flushing and drainage tubes on the market is very soft; on the one hand, when the tube body enters the human body and encounters obstacles, it often requires the operator to spend more effort Squeezing and pushing can make the drainage tube reach the operation area, which will not only easily cause strong discomfort to the patient, but also easily cause secondary trauma; on the other hand, the length of the tube body of the drainage tube will be limited, so that the drainage tube cannot Through the patient's throat, anus and other parts, it enters deeper into the body for suction, flushing and other operations
