Vulnerating experimental device based on composite craniocerebral injury in typical traffic accident

Abstract

The invention discloses a vulnerating experimental device based on a composite craniocerbral injury in a typical traffic accident. The device includes an acceleration device which includes an impact block and a boosting mechanism used for accelerating the impact block; and a deceleration device which includes a deceleration push plate and a deceleration buffering device acing on the deceleration push plate and also includes a pressure sensor A and an upper computer capable of receiving signals of the pressure sensor A, wherein the pressure sensor A is arranged on the impact block or a test chamber and is specifically arranged on a contact surface when the impact block impacts on the test chamber. Through the arrangement of the pressure sensor A and the upper computer capable of receiving the signals of the pressure sensor A, impact force can be accurately controlled, and thus an experiment has relatively high repeatability and operability.

Description

technical field [0001] The invention relates to a medical research experiment device, in particular to an injury experiment device based on a compound craniocerebral injury in a typical traffic accident. Background technique [0002] Craniocerebral impact injury is a common injury in traffic accidents. According to foreign statistics, the incidence rate of craniocerebral impact injury is as high as 54%, which is the primary cause of death and disability after injury. Pedestrians are in a disadvantaged position in road traffic accidents, coupled with the complex road environment where people and vehicles are mixed in my country, my country has become one of the countries with frequent pedestrian traffic accidents, and craniocerebral injury is the main cause of pedestrian death, so pedestrian cranial injury The study of brain impact injury is of great significance. Accelerated brain injury is a brain injury that occurs when a hard object hits a stationary head; deceleration br...

AI Technical Summary

Problems solved by technology

[0003] The research institutions use the deceleration injury device and the acceleration injury device respectively in the study of deceleration brain injury and acceleration injury. Both the wounding device and the accelerated wounding device have shortcomings such as poor repeatability and low experimental accuracy

In addition, in traffic accidents, it is often a compound brain injury in which acceleration injuries and deceleration injuries are superimposed. At present, there is no relevant equipment to simulate compound brain injuries
