Abstract

The invention discloses a rotary fixer for detecting murine toe swelling, belonging to the technical field of pharmacological equipment. A step motor is fixed on a motor fixing plate; a step motor shaft is fixedly connected in a bottom plate seat through a screw; a fixing cover is bonded on a boss of a bottom plate; a movable cover and a fixed cover are aligned; a four-limb hole is formed at the two ends of a U-shaped frame of the movable cover respectively; a strip insertion hole is formed at the arc ends of the fixed cover and the movable cover respectively, and a murine tail limiting plate is inserted into the strip insertion hole; a four-limb hole is formed at the two ends of the U-shaped frame at the butt joint combination between the fixed cover and the movable cover respectively; a semi-four-limb hole is formed in the fixed cover and the movable cover respectively; a sponge compression spring is fixedly glued on a cover pressing plate; a head pressing sliding plate is a rectangular slot body, and two side plates are trapezoidal plates; screw holes are formed in the two trapezoidal plates of the head pressing sliding plate; a head pressing plate is mounted in the slot between the two trapezoidal plates of the head pressing sliding plate and fixed in the screw holes in the two trapezoidal plates of the head pressing sliding plate by a screw; and a head sliding plate fixing screw, a head pressing plate and a head pressing sliding plate form a head pressing component.

Description

technical field [0001] The invention relates to a rotating fixer for measuring rat toe swelling, in particular to a fixer for fixing experimental mice to be measured and driving the experimental mice to rotate, belonging to the technical field of pharmacological appliances. Background technique [0002] Currently, in pharmacological animal experiments, it is difficult to fix animals, and the known mouse toe swelling tester is not equipped with a rodent rotating fixator. The movable cover of the existing mouse immobilizer is laterally fixed, the toe is exposed to a small volume, and the measurement accuracy is low. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention provides a rotary fixer for measuring rat toe swelling, which can fix the experimental mouse and rotate the fixed experimental mouse according to the needs, and the measured value is accurate . [0004] The technical scheme of the present invention is: the str...
