An automatic speed measurement and automatic pulse cleaning device for external drainage of cerebrospinal fluid

Abstract

The present invention is an automatic speed measurement and automatic pulse cleaning device for external drainage of cerebrospinal fluid, which includes a housing, and the inside of the housing includes a liquid drop monitoring device, a one-way pump on the effusion side, a one-way pump on the saline side, connecting rods, gears, Drive gears, motors, and computer control chips. The one-way pump on the effusion side is composed of an effusion chamber and the left side of a synchronous piston located in the effusion chamber. The one-way pump on the saline side is composed of a saline chamber and a The right side of the synchronous piston in the normal saline cavity is formed; the left side of the synchronous piston divides the effusion cavity into the effusion cavity C and the effusion cavity D, and the right side of the synchronous piston divides the normal saline cavity into the normal saline cavity A, Physiological saline chamber B; the power output end of the motor is connected to a driving gear, the driving gear is meshed with a gear, the gear is connected to a connecting rod, and the connecting rod is connected to a synchronous piston. The automatic monitoring function of the present invention continuously monitors the drip rate of the external drainage of the cerebrospinal fluid, so as to prevent possible untimely discovery by manual monitoring and affect the treatment of patients.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an automatic speed measurement and automatic pulse cleaning device for external drainage of cerebrospinal fluid. Background technique [0002] During the treatment of neurosurgical diseases such as cerebral hemorrhage, hydrocephalus, and intracranial infection, external drainage devices for cerebrospinal fluid are often required. For example: in cases of cerebral hemorrhage, external drainage of cerebrospinal fluid can lead out bloody cerebrospinal fluid; in cases of hydrocephalus, external drainage of cerebrospinal fluid can reduce intracranial pressure; in cases of intracranial infection, external drainage of cerebrospinal fluid can lead out infected cerebrospinal fluid from the body. [0003] External drainage of cerebrospinal fluid includes external ventricular drainage, lumbar cistern drainage, etc. However, in the actual treatment process, due to various...

Problems solved by technology

[0003] External drainage of cerebrospinal fluid includes external ventricular drainage, lumbar cistern drainage, etc. However, in the actual treatment process, due to various reasons such as infection and hemorrhage, the drainage tube is blocked and the drainage is not smooth. The long-term drainage failure not only delays treatment, but also may cause Intended infection, leading to more serious consequences, even endangering the patient's life; it is extremely important to detect and deal with poor drainage in time, and rely on doctors, nurses, and the care of patients' family members in clinical work

However, in the actual operation process, especially in the middle of the night, it is often impossible to detect the poor drainage of the drainage tube in time, or even the state of the blocked tube, which delays the treatment
