A rat cerebrospinal fluid metering collection device with injection and pressure measurement functions
By designing a device that includes components such as a base plate, a support plate, and a hydraulic cylinder, the problem of collecting cerebrospinal fluid and injecting drugs in rats was solved. This enabled the accurate calculation of cerebrospinal fluid secretion and drug injection, meeting the needs of cerebrospinal fluid circulation research and reducing operational damage.

Abstract
This invention provides a rat cerebrospinal fluid (CSF) metering and collection device with injection and pressure measurement functions. The device includes a glass tube and a catheter. A pressure probe is installed inside the glass tube. A three-way valve is installed at one end of the glass tube, and the other two ends of the three-way valve are connected to tubing. This device facilitates drug injection, facilitates CSF collection, measures CSF pressure, observes the relationship between CSF flow rate, flow velocity, and intracranial pressure, and simulates and studies the effects of ventricular drainage surgery. The rat CSF metering and collection device with injection and pressure measurement functions provided by this invention has the advantages of being easy to use, capable of collecting CSF, and accurately calculating the amount of CSF secreted.
