Problems solved by technology

This method solves the problem of animal stress, but since the pressure measurement is performed after injecting normal saline, the pressure measurement can only be the result of one urination and cannot reflect the pressure change process before the animal urinates and the pressure change when the animal does not urinate. Poor sexuality, the result of one urination does not fully reflect its complete urination ability

Abstract

The invention provides a rat bladder internal pressure measuring device and a rat bladder internal pressure measuring method. The device comprises a biological signal collecting system and further comprises an injection pump, a bladder fistulization tube, a restrictive rat cage and a balance scale; the bladder fistulization tube comprises an injection tube and a pressure measuring tube, the injection tube is connected with the injection pump through a first catheter, and the piezometric tube is connected with the biological signal acquisition system through a second catheter; and the restrictive rat cage comprises a side plate and a hollowed-out laminate erected on the side plate, and a weighing plate is arranged right below the hollowed-out laminate. According to the rat bladder internal pressure measuring device and the rat bladder internal pressure measuring method, during rat bladder internal pressure measurement, the urination condition is close to the urination condition of a rat in a natural state, the catheter can be prevented from being bitten by the rat when penetrating out from a subcutaneous part, real-time dynamic measurement of the bladder internal pressure can be achieved, and experimental data are detailed.

Description

technical field [0001] The invention belongs to the field of laboratory measuring instruments, and in particular relates to a device for measuring intravesical pressure of rats and a method for measuring intravesical pressure of rats. Background technique [0002] The current methods for measuring intravesical pressure in rats mainly include the following: [0003] (1) Observing the urination of the rats with the naked eye: Before the experimental observation, the rats were given enough water, and the urination frequency and volume of each urination of the rats were observed with the naked eye within 24 hours, and the data were analyzed to judge the urination function of the rats. This method takes a long time and requires 24 hours to observe the urination of the rats, and it is impossible to directly measure the pressure change in the bladder during urination of the rats, and it is subjective, and the error of the experiment is relatively large. [0004] (2) Detection of i...
