Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-4, the embodiment provides a containing box for an electromyography evoked potential instrument, which includes a box body 1, an inner cavity of the box body 1 is divided into an upper containing cavity and a lower containing cavity, two long slide blocks are respectively fixed on two side walls of the upper containing cavity, the two long slide blocks are in sliding fit with U-shaped long slide rails 3 fixed on two sides of a drawer 2, the drawer 2 is slidably connected in the upper containing cavity through the U-shaped long slide rails 3 and the corresponding long slide blocks, the inside of the drawer 2 is divided into five placing grids 5 for placing an extension box 4, a top limiting block 6, a middle limiting block 7 and a bottom limiting block 8 are respectively fixed on two sides of the top, the middle and the bottom of the lower containing cavity, a partition plate 9 is fixed between the two middle limiting blocks 7 to divide the lower containing cavity into a first lower containing cavity 14 and a second lower containing cavity 15, the first layer lower part holds chamber 14 and has placed preamplifier 10 and preamplifier 10 spacing through top stopper 6 and middle part stopper 7, the second layer lower part holds chamber 15 and has placed electro stimulator 11 and electro stimulator 11 spacing through middle part stopper 7 and bottom stopper 8, the outside both sides that the chamber was held to the lower part are detachably connected with the vertical baffle 12 that is used for spacing preamplifier 10 and electro stimulator 11 respectively, the outside that the chamber was held to the lower part just is located two vertical baffles 12 covers and is equipped with lid 13.
