Experimental device for traumatic brain deceleration injury in simulated traffic accidents

Abstract

The invention discloses an injury experiment device for simulating a brain deceleration injury in a traffic accident. The device comprises a rack and an acceleration device, a rotating driving device,an experiment box, a simulation track and a deceleration device. The experiment box is arranged on the simulation track. The acceleration device and the deceleration device are arranged at the starting line and the finishing line of the simulation track respectively, the acceleration device is used for driving the experiment box to move on the simulation track, the acceleration device is used fordecelerating the experiment box, and the experiment box is used for fixing an animal needed by an experiment. According to the injury experiment device for simulating the brain deceleration injury inthe traffic accident, the deceleration injury mechanism process can be independently simulated, the diffusible axis cylinder injury causing mechanism process can also be simulated, the brain deceleration injury causing process with the diffusible axis cylinder injury in the traffic accident can be effectively simulated, the repeatability is high, and the experiment result is accurate.

Description

technical field [0001] The invention relates to a medical research experimental device, in particular to an experimental device for simulating trauma caused by craniocerebral deceleration injury in traffic accidents. Background technique [0002] Craniocerebral injury is a common type of trauma to the head and brain tissue. It ranks second only to limb injuries, accounting for 10%-20% of systemic injuries, but its mortality rate ranks first among all kinds of injuries. It includes Battle sign, offset brain injury, acceleration brain injury, diffuse axonal injury, and deceleration brain injury, where deceleration brain injury refers to brain injury that occurs when a moving head hits a stationary object. [0003] The degrees of injuries to patients in accidents vary. Hospitals can take timely and effective treatment for patients with obvious symptoms, but patients with insignificant symptoms are often ignored, especially for patients with brain impact. Most of them are in th...

Problems solved by technology

[0003] The degrees of injuries to patients in accidents vary. Hospitals can take timely and effective treatment for patients with obvious symptoms, but patients with insignificant symptoms are often ignored, especially for patients with brain impact. Most of them are in the brain, and in the absence of external bleeding or intracranial congestion, many patients did not feel any discomfort at that time, so they did not take corresponding detection and treatment, resulting in aggravation of the disease

[0004] In order to solve the above situation, some experimental simulation devices are currently designed, but these devices still have many shortcomings, such as low repeatability, poor precision, unreliable experimental data, etc.

For example, the Chinese Invention Patent Application No. 201410383601.5 discloses an experimental device for diffuse axonal injury, which drives two motors to rotate the animal's trunk and head relative to each other to analyze the effects of diffuse axonal injury on the head. However, in the past, diffuse axonal injury rarely occurred alone. In a car accident, the victim who was hit generally suffered from deceleration injury while landing with diffuse axonal injury. This kind of incidental diffuse axonal injury Due to the complexity of the symptoms and simulation experiments of deceleration injuries, a reasonable simulation experiment device has not yet been developed, so there are no corresponding results reported
