Experimental animal hollow organ and vessel pressure-tolerant mechanics test device

Abstract

The invention relates to an experimental animal hollow organ and vessel pressure-tolerant mechanics test device, belonging to the technical field of devices for animal experiment. The test device comprises a double-way pipe, a three-way pipe, a pressurization module and a pressure detection recording module, wherein the double-way pipe, the pressurization module and the pressure detection recording module are communicated with the three-way pipe, and the other end of the double-way pipe is communicated with a closed hollow organ or a vessel to be tested. During an experiment by using the test device provided by the invention, the pressurization module is used for pressurizing the inside of the hollow organ or the vessel to be tested, and the pressure detection recording module is used for detecting and recording the pressure data in real time; once the hollow organ or the vessel is broken, the highest pressure data recorded by the pressure detection recording module is the bursting pressure so that the experimental process is simple, the observation is visual, and the experimental data is accurate and scientific. The experimental animal hollow organ and the pressure-tolerant voltage mechanics test device has the advantages of simple structure, low cost and wide application range.

Description

technical field [0001] The invention relates to the technical field of equipment for medical experiments, in particular to the technical field of equipment for animal experiments, in particular to an experimental animal cavity organ and blood vessel pressure resistance testing device. Background technique [0002] In the field of medical experiments, it is usually necessary to conduct experiments on the pressure resistance or tension of specific blood vessels or organs to determine their rupture pressure, so as to understand the recovery or anastomosis of blood vessels or organs using specific drugs or treatment methods growth status, and then judge the therapeutic effect of corresponding drugs or treatment methods. [0003] In the prior art, such experiments usually place tissues (including normal intestine, anastomotic intestine, incision skin, blood vessels, etc.) between the two grippers of the test instrument, apply a tension of 10 Newtons to the cells, and use 10 The ...
