Embodiment approach

[0048] As a specific implementation of the rat crush injury mold provided by the present invention, please refer to Figure 4 , The fixing assembly 2 includes: a fixing frame and a plurality of fixing pieces 11 . The fixed frame has a hollow structure and is plugged into the socket slot 16; a plurality of fixed rings 9 are fixed on the inner wall of the fixed frame; Connected to the bottom of the slot 16. A plurality of fixing parts 11 correspond to the fixing ring 9 one by one; one end is connected to the fixing ring 9, and the other end is used for connecting with the rat's leg. The fixed frame is a hollow frame body, and the wall body of the fixed frame is rigid and thin. The wall body of the fixing frame can be inserted into the insertion slot 16 , and the fixing frame can be abutted against the insertion slot 16 , that is, the base 1 , by pressing the fixing frame. The structure of the fixed frame is arranged along the outer edge of the base 1. A plurality of fixed rin...

Abstract

The invention provides a rat extrusion injury mold and an extrusion injury experimental method, and belongs to the technical field of simulated extrusion injury. The rat extrusion injury mold comprises a base, fixing components, supporting frames, a plurality of extrusion mechanisms and rotating parts; the top of each of sliding rails is penetrated by a clamping groove; the plurality of extrusionmechanisms sleeves and are slidably arranged on the sliding rails; the bottom of each extrusion mechanism is provided with an extrusion part which is used for extruding a leg of a rat; each rotating part penetrates through and is in threaded connection with the top part of one corresponding extrusion mechanism, and is clamped and slidably arranged in one correponsing clamping groove; the extrusionmechanisms drive the rotating parts to slide along the clamping grooves; and the extrusion mechanisms drive the extrusion parts to move downwards by threaded force of the rotating parts so as to extrude the leg of the rat. The extrusion injury experimental method is carried out by adopting the rat extrusion injury mold. The rat extrusion injury mold and the extrusion injury experimental method provided by the invention can adapt to extrusion of legs of rats with different sizes and have high applicability.

Description

technical field [0001] The invention belongs to the technical field of crush injury simulation, and more specifically relates to a rat crush injury mold and a crush injury experimental method using the rat extrusion upper mold. Background technique [0002] In the rat experiment, it is necessary to place a certain weight on the leg of the rat. After the preset time is reached, a series of studies such as dissection of the rat are carried out, so as to analyze and determine that the human being is squeezed by the heavy object. Subsequent muscular changes. Due to the different sizes of the rats, there are certain differences in the positions of the legs, and the existing extrusion upper dies cannot be adjusted accordingly according to the positions of the legs of the rats, resulting in poor applicability. Contents of the invention [0003] The object of the present invention is to provide a rat crush injury mold and a crush injury experiment method, aiming to solve the prob...
