Rate cardiac perfusion fixer

Abstract

The invention discloses a rate cardiac perfusion fixer, which is a rate dissection blood-sampling or perfusion article for use in medical and pharmaceutical laboratories. The entire rate cardiac perfusion fixer is a cuboid framework which is 20 millimeters in height and 15 millimeters in width. The rate cardiac perfusion fixer is characterized in that the framework is formed by splicing two completely symmetric portions, is made of plastic and is compression-molded at one time. Upper and lower four edges constructing the framework and a four-edge framework on the body portion are cylinders of phi2 millimeters. Equilateral rhombus spacing frames are arranged on upper port and lower port square frames, frames shaped as the Chinese character 'Tian' are arranged on left and right faces, and splicing surfaces of six circular rings are formed on front and back faces. Crossed frameworks in the left and right faces are provided with millimeter graduation marks. Splicing portions of the fixer consist of female heads and male heads which are matched one above the other in a staggered way in order to ensure that two splicing bodies are completely symmetric. During use, the two splicing bodies are spliced together, and the heart is held in the framework in order to perform heart blood taking or perfusion.

Description

Technical field: [0001] Medicine, pharmacy teaching and scientific research experiment equipment. Background technique: [0002] In medical and pharmaceutical animal experimental research, rat experimental research is a relatively common experimental link. Various experimental research animal models, drug metabolism and drug evaluation require blood collection and pathological observation of corresponding organs. Common methods use cardiac bleeding, transaortic perfusion to flush blood from organs, or focus on fixatives to keep tissue samples fresh. In the above operation, the operation is difficult due to the beating of the heart, blood collection is easy to cause hemolysis, and the heart is not easy to fix during perfusion. So far, the above-mentioned operations can only be performed by butcher's hands, and there are no tools that can be used. The heart is only operated on with personal experience and skills. People often ask for help on the Internet to solve the hemolys...
