Intracranial hematoma drainage device

Abstract

The invention discloses an intracranial hematoma drainage device, and belongs to the field of medical instruments. According to the technical scheme, the drainage device is characterized by comprisinga drainage tube and a pull rod, wherein the pull rod is inserted into an inner cavity of the drainage tube through the insertion end of the drainage tube, a drainage opening is formed in the wall ofthe drainage tube, is in a long strip shape and is formed in the length direction of the drainage tube, a shielding sheet covers the drainage opening, one end of the shielding sheet is fixedly connected with one end of the drainage opening, and the other end of the shielding sheet is a bent end; a sliding rail is arranged on the inner wall of the shielding sheet in the length direction of the shielding sheet; and a supporting rod is arranged in the inner cavity of the drainage tube and perpendicularly and fixedly connected with the pull rod, and a sliding block is fixedly arranged at the end of the supporting rod, penetrates out of the drainage opening outwards and is arranged in the sliding rail in a sliding mode. An elastic device and a collecting device are arranged to expand the sectional area of the drainage opening and prevent the drainage opening from being blocked; the bendable shielding sheet is arranged on the drainage opening to prevent surrounding tissue from shielding thedrainage opening; and a negative pressure ball on the collecting device can generate negative pressure, and thus the negative pressure drainage effect of the negative pressure ball is improved.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to an intracranial hematoma drainage device. Background technique [0002] Intracranial hemorrhage refers to the bleeding caused by the rupture of blood vessels in the brain. Therefore, the brain cells that receive blood from the blood vessels are destroyed, and at the same time, the surrounding nerve tissue is blocked due to hemorrhage. Usually, intracranial hemorrhage will be combined with hyperthermia. This symptom will Increase the oxygen consumption of the brain, thereby causing 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 circumferential direction. The material of the tube body is elastic sol...

Problems solved by technology

[0006] The technical problem to be solved by the present invention: the drainage hole of the drainage tube currently used is small, which may easily cause the blockage of the drainage hole and cause the use effect of the drainage tube to deteriorate; because the surrounding tissue has a certain elasticity, it is easy to cause the tissue to fit the drainage hole , which leads to the blockage of the drainage hole and the poor effect of the drainage tube; and the intracranial pressure is small, and the back 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 of the patient. and rehabilitation effect, providing a drainage device for intracranial hematoma
