Electrophysiological comprehensive experiment shielding box

Abstract

The invention discloses an electrophysiological comprehensive experiment shielding box. The shielding box mainly comprises a box body, a box cover, electrodes, nerve trunk tissue fixing devices and multifunctional liquid tanks, wherein a movable conductive pole assembly, a specimen fixing device, the nerve trunk tissue fixing devices, a thighbone fixing seat of a muscle specimen fixing device, a muscle specimen fixing device screw, a general liquid tank (24) and a side cover of a side drawer sample are arranged in the box boy, and a first handle is arranged on the side cover of the side drawer sample; the box cover is provided with a staff gauge, a gap, an opening and a specimen shielding moisturizing cover or a shielding moisturizing surrounding bucket, wherein the gap is used for moving a sliding positioning block, the opening is correspondingly formed in a muscle fixing device in the box body, the specimen shielding moisturizing cover or the shielding moisturizing surrounding bucket covers the opening, a second handle is arranged on the specimen shielding moisturizing cover, the muscle fixing device comprises the thighbone fixing seat and the muscle specimen fixing device screw, and the shielding moisturizing surrounding bucket comprises two parts, namely a bucket body and a bucket opening. The electrophysiological comprehensive experiment shielding box has the characteristic of convenience in operation and is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of electrophysiological experiments, and relates to a shielding box for comprehensive electrophysiological experiments. Background technique [0002] At present, when doing electrophysiology and pharmacology teaching experiments, there are four main problems in the response of animal nerve activity and body tissue: First, the nerve and muscle tissue are separated, and the experimental records and analysis are completed separately. The electrical conduction activity of the nerve or the movement state of the muscle tissue can be seen separately, and the synchronous comprehensive analysis cannot be carried out and the internal connection between the two can be reflected; the second is the process of moving the electrode, because there is no scale and the nerve trunk is not fixed, it is impossible to accurately locate the nerve The stimulation and recording position of the stem; the third is that the conditions ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the defects in the prior art that the muscle nerves cannot be observed simultaneously, the nerve trunk cannot be accurately located, the experiments under different conditions cannot be effectively controlled, and the experimental materials are not well sealed, and to solve the above technical problems, the present invent...
