Problems solved by technology

[0002] At present, in the pharmacological animal experiments, the mouse toe swelling measuring instrument can measure the data of the mouse toe swelling, but, in the measurement, due to the poor positioning of the mouse, the existing fixed movable cover of the mouse is fixed in the side position, and the toe is fixed. The exposed volume is small and the measurement accuracy is low, resulting in inaccurate measurement data

Abstract

The invention discloses a murine toe swelling tester, belonging to the technical field of pharmacological appliances. A total bearing plate is a rectangular body, a gravity pillar is arranged at one side of the upper end of the total bearing plate, the gravity pillar is connected with a measurement platform and a gravity sensor at the lower end of the total bearing plate by bolts, one end of the gravity sensor is connected with a sensor support, the other end of the gravity sensor is connected with a gravity support, and a measurement cup is placed on the upper end of the measurement platform; the other side of the upper end of the total bearing plate is connected with a stand column frame by bolts, the top end of the stand column frame is connected with an upper end plate by bolts, a lifting threaded rod is arranged at the front end of the stand column frame, the upper end of the lifting threaded rod is mounted on the upper end plate, a motor fixing plate of a rotation fixator is connected with a lifting board by a bolt through threaded holes of the lifting board, and one end of the motor fixing plate is connected with a rotation fixator motor; a detection channel is arranged on a measurement circuit board, and is electrically connected with an LM 358 direct current signal amplification module, the LM 358 direct current signal amplification module is connected with the gravity sensor, the measurement circuit board is electrically connected with an RS 232 communication port, and the RS 232 communication port is connected with a computer.

Description

technical field [0001] The invention relates to a mouse toe swelling measuring instrument, which belongs to the technical field of pharmacological instruments. Background technique [0002] At present, in the pharmacological animal experiments, the mouse toe swelling measuring instrument can measure the data of the mouse toe swelling, but, in the measurement, due to the poor positioning of the mouse, the existing fixed movable cover of the mouse is fixed in a lateral position, and the toe is fixed. The exposed volume is small and the measurement accuracy is low, resulting in inaccurate measurement data. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings, the present invention provides a mouse toe swelling measuring instrument, which can precisely fix the experimental mouse, and use the weighing method to input the volume into the AD converter with a voltage in a gravity mode, Through the RS232 interface, it is transmitted to the micro...
