Ventricular drainage device

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a ventricular drainage device which comprises a base, a vertical plate is fixedly connected to the topof the base, a pair of sliding rails is fixedly connected to the vertical plate, and sliding grooves are formed in the adjacent sides of the sliding rails; a sliding block is slidably connected into the sliding groove, and a lead screw penetrates through the sliding block. A drainage bottle is fixedly connected to the sliding block, the bottom of the drainage bottle communicates with a hose, and the other end of the hose communicates with the ventricle to-be-drained part; a pressure chamber is arranged in the middle of the hose, a cylinder is fixedly connected to the inner wall of the pressurechamber, an elastic film is hermetically connected to one end, away from the inner wall of the pressure chamber, of the cylinder, and a conductive coating is coated on one side, in the cylinder, of the elastic film and connected with the controller through a wire; according to the ventricular pressure balance adjusting device, after the elastic film is deformed, the conductive coating is electrically connected with the contact column, then the controller controls the drainage bottle to stop lifting the height, and then ventricular pressure balance is quickly adjusted.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a ventricle drainage device. Background technique [0002] Ventricular puncture and drainage is a commonly used treatment method in clinical massive cerebral hemorrhage craniotomy. Through ventricular drainage, cerebrospinal fluid and intracranial hemorrhage are drained outside the brain, thereby reducing the pressure on brain tissue and controlling intracranial pressure. Reduce cerebral edema. The height of postoperative ventricular drainage suspension should usually be about 15-20 cm from the apex of the drainage drip pot to the scalp puncture point, so as to allow adequate drainage and maintain normal intracranial pressure. At present, the method of external ventricular drainage is to draw out the cerebrospinal fluid of the ventricle through a drainage tube and transport it into a drainage bottle. Because the drainage height of the drainage bottle has an extremely im...
