Cerebrospinal fluid drainage device and method based on intracranial pressure monitoring

Abstract

The invention discloses a cerebrospinal fluid drainage device and method based on intracranial pressure monitoring, and relates to the technical field of medical instruments. The device comprises a drainage tube, a drainage bag and a lifting device, a drainage opening is formed in the head end of the drainage tube, a branch tube is arranged on a tube body of the drainage tube, and an intracranial pressure monitoring device is connected into the branch tube; the tail end of the drainage tube is connected with a sample reserving tube and a connecting hose; a three-way valve is arranged at the joint of the tail end of the drainage tube, the sample reserving tube and the connecting hose; the drainage bag is connected with one end of the connecting hose, and a water drop flow velocity detection device is arranged on the drainage bag; the lifting device is connected with the drainage bag, a control system is arranged in the lifting device, the control system is in communication connection with the intracranial pressure monitoring device and the water drop flow speed detection device, and the control system controls operation of the lifting device so as to drive the drainage bag to move up and down. According to the cerebrospinal fluid drainage device and method based on intracranial pressure monitoring, the height of the drainage bag is automatically adjusted according to the monitored pressure value and the water drop flow speed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cerebrospinal fluid drainage device and method based on intracranial pressure monitoring. Background technique [0002] There are problems with the cerebrospinal fluid drainage devices currently used in clinical practice: (1) the measurement is not accurate, the cerebrospinal fluid drainage volume needs to be calculated precisely, and the requirements for sterility are high, and the drainage fluid of the previous day cannot be opened every day, and the drainage fluid accumulated in several days Together, it increases the difficulty of observation. (2) It is inconvenient to collect cerebrospinal fluid samples: frequent opening as above increases the risk; and the flow rate of ventricular drainage fluid is slow, and it takes a long time to collect the required amount after opening; using the fluid in the drainage bag cannot correctly reflect the current situation , becau...
