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...
