Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with accompanying drawing:

[0032] Such as Figure 1-3 Shown:

[0033] A kind of wounding experiment device based on compound craniocerebral injury in typical traffic accidents of the present invention comprises the following components:

[0034] A test box 1, which is used to hold or fix the test object; preferably, the test box 1 is made of light materials, such as aluminum alloy materials or plastic materials;

[0035] Acceleration device, which includes a bumper 2 and a booster mechanism 3 for accelerating the bumper; preferably, the booster mechanism includes a turntable 11, a rotating shaft 12 arranged in the middle of the turntable 11, and a drive mechanism arranged below the turntable 11. A motor 13 for rotating the rotating shaft. The rotating shaft 12 is provided with a traction arm 14 extending towards the edge of the turntable. The end of the traction arm 14 is provided with a magnetic...

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...
