Description
Technical field
The present invention relates to a kind of assay device studying traumatic brain injury, slow down particularly to one and hinder injury device.
Background technology
Deceleration injury (injury of deceleration) refers to that wounded's head clashes into the most suddenly
Object and stop caused brain injury.The distribution of deceleration brain injury both can betide puts forth effort position, it is possible to
Betide the position that liquidates, i.e. shock point wound and contre coup injury occurs the most simultaneously.Described shock point wound refers to impetus
Place collides with inner table of skull mutually simultaneously because skull temporary deformity or fracture are caved at impetus on brain surface, causes
The damage of cerebral tissue below impetus；Described contre coup injury refers to that the offside of impetus i.e. liquidates position, due to entirely
Brain to putting forth effort side mass movement, rough bone ridge at the bottom of the brain bottom surface at the position that liquidates and anterior cranial fossa and middle cranial fossa
Rubbing mutually, brain surface is collided with bone jut, the brain injury caused.The feature of deceleration injury is not
With density cerebral tissue generation relative displacement, producing tangential wound, itself and contre coup injury are the most more serious, even specific impulse wound
Even more serious.The most reasons causing on-board crew brain injury in vehicle accident are caused by wound of slowing down,
For deceleration being hindered patient and carries out in time, diagnosis and treatment accurately, patient is lapsed to have decisive meaning,
Therefore, set up good deceleration and hinder animal model to research deceleration wound is machine-processed and Therapeutic Method has particularly significant
Meaning.
The presently disclosed technical information about deceleration wound model is little, and rare is that Tan Yuanfu et al. is at one
Entitled " establishment of deceleration brain injury animal model " (see: China's wound magazine, 2001,17 (4):
Article 212-215) discloses a kind of deceleration wound model, this model uses elastic band trial target is carried out
Accelerate, then make trial target be obstructed suddenly and clash into deceleration, be allowed to be injured by deceleration.Its concrete grammar is:
Rabbit head is placed in flap front end, applies maximum pull with elastic band in vertical position in flap rear end, clash into front wink
Between, rabbit head obtains maximal rate, when be obstructed suddenly shock time cranium brain caused injury by deceleration.This model
Advantage is simple in construction, low cost；Shortcoming is a lack of testing degree of accuracy and repeatability.
Additionally, the Chinese patent of Application No. 200810237275.1 (hinders causing injury of experimentation for slowing down
Device and the method making deceleration wound model) disclose another deceleration wound model, this model is by animal
Trial target is from eminence free-falling and clashes into chopping block, thus causes the cranium brain of animal experiment product to slow down and hinder.This mould
The advantage of type is that simple in construction, experimental cost are low, and its shortcoming is: 1, wayward falling speed, experiment
Degree of accuracy is the best；2, the product individual variation that is put to the test impact substantially, lacks repeatability.
