Twin-tube drainage tube

Abstract

The invention relates to medical appliances and particularly relates to a twin-tube drainage tube. The twin-tube drainage tube is used for overcoming the disadvantages of the existing drainage tubes that main drainage tube bodies are prone to slipping and cannot be accurately located. The twin-tube drainage tube comprises a guiding head, wherein one end of the guiding head is connected with a maindrainage tube, the other end of the guiding head is in sleeve joint with a drainage tube and a drug injection tube separately, a partition petal is arranged inside the main drainage tube, a high-density locating filler is embedded in the internal wall of the end part of the main drainage tube, and a fixed sleeve sleeves the outside of the main drainage tube. An adhesive sticker is stuck by usingan adhesive adhered to the surface of a cushion pad of one end of a fixed sleeve, the fixed sleeve can be stuck to scalp of a sufferer, an anti-slipping pad of the internal wall of the fixed sleeve isin fit with the surface of the main drainage tube by using inflated expansion of an air bag inside the fixed sleeve, friction is generated, and the functions of fixing the main drainage tube to the head of the sufferer and preventing slippage are achieved; and meanwhile, the air bag uniformly wraps and applies a force to the surface of the main drainage tube, so that circumstances of blockage caused by extrusion can be prevented, and the practicability is high.

Description

technical field [0001] The invention relates to medical instruments, in particular to a double-pipe drainage tube. Background technique [0002] At present, the main drainage tube used in minimally invasive drainage of hematoma cavity for hypertensive cerebral hemorrhage is mostly a single-lumen main drainage tube, which is prone to blockage of the main drainage tube, resulting in poor drainage. In addition, during the operation, it is necessary to inject medicine into the hematoma cavity, and the injection and suction of the hematoma are the same pipeline, which is prone to the backflow of the hematoma fluid, the insufficient effect of the medicine, and the increased probability of infection. [0003] China Novel: CN201720609057.0 discloses a three-chamber brain drainage tube, the drainage tube includes a main drainage tube body, and one end of the main drainage tube body for inserting into a patient's craniocerebral lesion is provided with a guide head, and the main draina...
