Injury-causing device for experimental investigation of deceleration injury and method for producing deceleration injury model

Abstract

The invention discloses an injury making device for deceleration injury experimental research and a method for making a deceleration injury mould. A space for the pulley falling is existed between an upper supporting seat and a substrate. The space is internally and vertically provided with a guided way. The pulley is arranged between the upper supporting seat and the substrate and is matched with the guided way by a rolling device in a rolling way. The substrate is provided with a chopping block and a device used for buffering and deceleration. An animal is fixed on the pulley. A bracket is used for holding the position of the animal needing to be injured. The pulley is caused to freely fall along the guided way so that the position of the animal needing to be injured collides with the chopping chock. The device used for buffering and deceleration controls deceleration so as to form the deceleration damage of the position of the animal needing to be injury, thus obtaining the mould of the deceleration injury. The invention overcomes the shortcomings of the existing injury making device for deceleration injury and the method for making the deceleration injury mould, is economical and scientific and can be widely used in the fundamental research of medicines such as traffic medicine, physical exercise medicine, aviation and aerospace and etc.

Description

technical field [0001] The invention relates to the field of trauma experiments, in particular to a wounding device used for experimental research on deceleration injuries and a method for making a deceleration injury model. Background technique [0002] Deceleration injuries are injuries caused by a moving creature colliding with other objects suddenly, forcing the creature to slow down in a very short period of time. Deceleration injuries are common in traffic accident injuries, high-altitude fall injuries, and sports injuries. [0003] With the development of society, human beings have more and more means of transportation, and the number of traffic accident injuries caused by traffic accidents has increased. Traffic safety has become a serious threat to human health. Traffic accident injuries are also listed as the most harmful to human life safety. The "World's No. 1 Public Hazard" has a great impact on social stability and economic development. Common types of injuri...

Problems solved by technology

Gravitational acceleration using free fall is a more economical experimental method. It releases experimental animals to fall freely from a certain height to obtain the initial velocity. Although this method can achieve the purpose of controlling the initial velocity, it cannot solve the damage of the experimental object. The positioning of the parts and the control of the deceleration process, due to the poor controllability of the experiment, the resulting deceleration injury model is not ideal, and it is not easy to meet the expected requirements

The elastic contraction is used to provide power to the experimental object to obtain the initial velocity, but the elastic will cause rubber fatigue and material aging as the number of tests increases, and there are still differences in material properties between different manufacturers and different batches of elastic , In addition, the mechanical conditions of rubber bands vary greatly under different temperature conditions. In view of these reasons, there are uncertainties in the stability of repeated experiments in the way of elastic contraction acceleration, and the reference value of the deceleration injury model produced is not enough for research. ideal

It is a better choice in terms of experimental accuracy and repeatability to make deceleration injury models by motor-driven steel cable traction, but because of its complicated operation, high-power motors consume a lot of electric energy, resulting in experimental costs increase, which is not economical and wastes energy

In view of the above reasons, in the research of deceleration injury in the field of traffic medicine, what kind of equipment should be used to make a deceleration injury model, which can not only solve the positioning of the experimental object and the control of the deceleration process, but also ensure the stability of the acceleration process and deceleration process. It can also reduce the cost of experimental research and easy operation, but has not been able to find an ideal solution
