Embodiment

[0027] Such as Figure 1~3 As shown, the multifunctional experimental animal impact machine includes a platform, a spring force device arranged on the top of the platform, a bumper connected to the spring force device, and a backing plate 15 positioned below the bumper, and the bottom of the backing plate is A pressure sensor 1 is provided.

[0028] The method of use is as follows: Expose the required impact object to the backing plate, fix it, slowly pull the bump head upwards with both hands, compress the spring force device, and then release the bump head instantly, and generate a strong force during the process of the spring force device returning to its original state. The power pushes the bumper to quickly strike the research object on the backing plate. After the impact, the pressure sensor senses the impact force to measure the actual pressure.

[0029] Specifically, the spring force device includes a hollow cylinder connected to the stand, and a spring 2 arranged in ...

Abstract

The invention discloses a multifunctional experimental animal impacting machine, which solves the problem that the existing impacting machine is inaccurate in data reading. The multifunctional experimental animal impacting machine comprises a saddle piece, a spring power generation device arranged at the upper part of the saddle piece, an impacting head connected with the spring power generation device, and a cushion plate which is disposed below the impacting head, wherein a pressure sensor is arranged on the bottom of the cushion plate. The multifunctional experimental animal impacting machine is simple to operate, low in cost and good in controllability and repeatability; sensing is performed by adopting the pressure sensor, so data is more accurate.

Description

technical field [0001] The invention relates to a multifunctional experimental animal impact machine. Background technique [0002] With the progress of industrialization, various types of trauma such as traffic injuries and falls from heights have risen sharply around the world. Worldwide, about 5 million people die from various types of trauma every year. Studying the pathophysiology of various types of trauma through animal experiments has extremely important clinical significance and can provide a strong theoretical basis for improving the prognosis of trauma patients. However, the trauma animal models established at home and abroad are difficult to truly and effectively simulate the occurrence and development of trauma, and at the same time, they cannot accurately measure the impact force, which makes it difficult for trauma animal experiments to provide a good theoretical basis for clinical practice. Contents of the invention [0003] The purpose of the present inve...
