Intracranial hematoma drainage device

Abstract

The invention provides an intracranial hematoma drainage device. The intracranial hematoma drainage device comprises a drainage tube, a pull rod, a drainage port formed in the wall of the drainage tube and in a strip shape and arranged in the length direction of the drainage tube, a shielding sheet covering the drainage port, a sliding rail arranged on the inner wall of the shielding sheet and arranged in the length direction of the shielding sheet, a supporting rod arranged in the inner cavity of the drainage tube and vertically and fixedly connected with a pull rod, a sliding block fixedly arranged at the end of the supporting rod, outwards penetrating through the draiagen port and slidingly arranged in the sliding rail, and is provided with an elastic device and a collecting device, wherein the drainage tube is inserted into an inner cavity of the drainage tube from an insertion end of the drainage tube, one end of the shielding sheet is fixedly connected with one end of the drainage port, and the other end of the shielding sheet is a bent end. The sectional area of the drainage port is increased, the drainage port is prevented from being blocked, the bendable shielding sheet isarranged on the drainage port, surrounding tissues are prevented from blocking the drainage port, a negative pressure ball on the collecting device can generate negative pressure, and the negative pressure drainage effect of the negative pressure ball is improved.

Description

technical field [0001] The invention belongs to the technical field of cranial nerve medical equipment, and in particular relates to a drainage device for intracranial hematoma. Background technique [0002] Intracranial hemorrhage (abbreviation: ICH) refers to the bleeding caused by the rupture of blood vessels in the brain. Therefore, while the brain cells that obtain blood from the blood vessels are destroyed, at the same time, the surrounding nerve tissue is caused by bleeding pressure. Usually, intracranial hemorrhage and body temperature Too high and combined, this symptom will increase the oxygen consumption of the brain, resulting in insufficient oxygen supply to the brain. To treat this symptom, the intracranial hematoma needs to be drained by drainage. [0003] In the prior art, the drainage tube used includes a circular tube body with a closed front end and an open rear end. Two rows of symmetrical holes are arranged on the front side of the tube body in the circ...

Problems solved by technology

[0004] However, the drainage holes of the drainage tubes used in the prior art are relatively small, which can easily cause blockage of the drainage holes and lead to poor use of the drainage tubes; due to the certain elasticity of the surrounding tissues, it is easy to cause the tissues to fit the drainage holes, thereby causing drainage. The blockage of the drainage tube leads to poor use of the drainage tube; and the intracranial pressure is small, and the rear end of the drainage tube is directly connected to the outside world. It is difficult to discharge the intracranial hematoma by natural pressure, which affects the recovery speed and effect of the patient.
