Neurosurgical negative-pressure drainage support capable of controlling pressure accurately

Abstract

The invention discloses a neurosurgical negative-pressure drainage support capable of controlling pressure accurately. The neurosurgical negative-pressure drainage support comprises a base. Universal wheels are fixed to the four corners of the bottom end of the base respectively. A sleeve is fixed to the top end of the base. A negative pressure barrel is arranged on the left side of the sleeve. The upper left side of the negative pressure barrel is connected with a connector in a matched mode through a sterilization device and a connection pipe. A pressure gage is fixed to the right side of the connector through a connection pipe. The right side of the pressure gage is connected with a micro suction pump through a connection pipe. The top end of the sleeve is connected with a telescopic rod through a telescopic adjustment mechanism. A steering mechanism is fixed to the top end of the telescopic rod through a bearing pedestal. A locking nut is fixed to the side wall of the steering mechanism. The side wall of the steering mechanism is further connected with one end of an L-shaped support. A tray and a C-shaped elastic clamp are further fixed to the other end of the L-shaped support through connection rods. The neurosurgical negative-pressure drainage support is simple in structure, the height of the neurosurgical negative-pressure drainage support can be adjusted, and then pressure can be indirectly adjusted.

Description

technical field [0001] The invention relates to the technical field of neurosurgery medical equipment, in particular to a negative pressure drainage bracket for neurosurgery that can precisely control pressure. Background technique [0002] According to statistics, there are about 800,000 to 1,000,000 cerebral hemorrhage patients in my country every year, and the recurrence cases are estimated to exceed 1,000,000 per year. In addition, in recent years, with the development of transportation, construction and other industries, the number of cases of traumatic cerebral hemorrhage has risen sharply. At present, there are more than 500,000 new cases of traumatic cerebral hemorrhage patients every year. Moreover, the mass effect of cerebral hemorrhage causes high intracranial pressure, leading to and aggravating secondary cerebral edema and brain injury, causing various complications and threatening life. [0003] Extracranial drainage and lumbar puncture catheter drainage are c...

AI Technical Summary

Problems solved by technology

The drainage speed is directly related to the pressure in the drainage bag. However, if the pressure is too high, it will cause life-threatening to the patient, and if the pressure is too small, it cannot meet the needs of neurosurgery drainage, which brings great harm to the medical staff. Trouble, increasing the difficulty of the work of medical staff

However, most of the traditional drainage stents use the method of manually adjusting the height of the stent to change its pressure. The pressure increase range of the drainage bag is limited, which cannot satisfy the normal drainage work
