Description
Technical field
The utility model belongs to medical experiment equipment, animal centrifuge video harvester particularly, it is by observing the performance of rat in animal centrifuge, thereby set up the rat model of brain damage due to the positive acceleration that centrifuge produces, comprising the design and the collecting image of computer analysis of the special fixture of rat.
Background technology
Fighter plane does motor-driven or during aerobatics, the centripetal acceleration direction that is produced is pointed to canopy by the passenger cabin bottom.Under this accelerated motion situation, the pilot must be subjected to the centrifugal inertial force effect opposite with acceleration, and its direction is by head points pelvis (foot).Claim that in aeromedicine this acceleration is a positive acceleration, the inertia force that the pilot is subjected to is expressed as+Gz.In recent years, high-performance fighter aircraft can produce high G value (〉 9G in maneuvering flight), rapid onset rate (〉 6G/s) continuation+Gz, and occur repeatedly.The physiological effect of+Gz mainly shows as the health apparent weight to be increased, and organ deforms, is shifted along the inertia force direction, and hydrostatic pressure difference increases, and blood generation inertia shifts and redistribution, thereby causes various physiological function obstacles.The pilot threatened maximum be exactly+the loss of consciousness (G-LOC) that Gz causes.Think that at present G-LOC mainly is because under+Gz effect, the horizontal arterial pressure of brain reduces, the cerebral blood flow (CBF) minimizing, and then cause (Kurihara et al, 2007 due to brain tissue ischemic, the anoxic; McKinley et al, 2005; Ossard et al, 1994).Confirm in the animal experiment study of this respect+cerebral ischemia that Gz causes can cause brain damage and damage in learning and memory (Cao XS, et al, 2007; Sun XQ, et al, 2005), be the important topic of domestic and international Research Aviation Medicine so prevent and treat the cerebral ischemia that positive acceleration causes.
In the basic research of this respect, the conventional animal centrifuge produces positive acceleration and sets up the cerebral ischemic model that the loss of consciousness takes place animal, because the special operational condition (high speed rotating) of animal centrifuge, limited some advanced physiology monitoring The Application of Technology, at present when setting up the animal model of simulation G-LOC, the index that the loss of consciousness takes place the monitoring animal mainly contains: the horizontal arterial blood platen press of monitoring eye, 50% death rate method, the heart rate halving method, electrocardio disappearance method, (Sun Xiqing etc. such as brain wave disappearance method, 2009), we think and judge that by these indexs the defective that the loss of consciousness exists takes place animal at first is not directly perceived, and have predictive.
Rat is fixed in when rotating on the animal centrifuge pivoted arm, requires the rat cephalocaudal axis parallel, and head is towards the centrifuge axle center with the pivoted arm major axis.In the zoopery in the past; on the centrifuge fixedly the device of animal (rat) be a rectangle box; can not regulate size; rat retraction, rotary head can occur even self-protection gonosome position such as turn round in box; thereby weakened+influence of Gz; the success that is difficult to like this guarantee model becomes we carry out prophylactico-therapeutic measures research on this model basis bottleneck with stable.
Summary of the invention
But the purpose of this utility model provides a kind of intuitive analysis animal behavior state performance, find out rule, and then the animal centrifuge video harvester of G-LOC takes place in the judgement animal, thereby set up the G-LOC animal model, the pathophysiological mechanism and the prophylactico-therapeutic measures that cause brain damage for research positive acceleration provide stable basis.
The purpose of this utility model is achieved in that the animal centrifuge video harvester, it is characterized in that: comprise a centrifuge rotating shaft at least, centrifuge rotating shaft driving mechanism, the centrifuge rotating shaft is connected with the centrifuge pivoted arm is vertical, make the centrifuge pivoted arm parallel with the centrifuge base station, the horizontal centrifuge pivoted arm other end is the zoopery platform fixedly, the shooting of one wireless camera unit is fixed on the position of horizontal centrifuge pivoted arm 7 near the centrifuge rotating shaft, quickcam image focusing is on the zoopery platform, the wireless camera unit is with extracting the fixedly animal painting information of zoopery platform, be sent to a control computation unit by wireless mode, when the rotating shaft of centrifuge rotating shaft drive mechanism centrifuge is rotated, the centrifuge rotating shaft drives the fixing zoopery platform of the centrifuge pivoted arm other end when the centrifugal rotation of axle, control computation unit receives storage to animal painting information and analyzes, and judge whether animal the loss of consciousness (G-LOC) has taken place, when the loss of consciousness (G-LOC) does not take place, continue to quicken centrifugal rotation zoopery platform, drive the animal centrifugal motion; When the loss of consciousness (G-LOC) took place, control computation unit provided information, and control centrifuge rotating shaft driving mechanism stops operating.
It is raising rotating speed at interval that drive animal centrifugal motion is changeed in described control centrifuge rotating shaft drive mechanism centrifuge rotating shaft.
Described control computation unit animal painting information is received storage and analyze comprise extract that struggle state, the passivity head of animal under apocarpy in the image raise position and time of origin, fore paw grab the state of climbing, mouth breathing, spasm and time of origin, respiration rate, time and image when eyeball color different conditions produces.
Described fixedly zoopery platform comprises a U type support, animal passenger cabin, height adjusting ring, chest retainer plate, head movement framing mask, the animal passenger cabin is fixed in the U type support, U type support and horizontal centrifuge pivoted arm are fixed together, the animal passenger cabin is round tubular structure, round tubular structure one end is a hatch door, height adjusting ring, chest retainer plate are arranged in the chamber, and another outlet of round tubular structure has the head movement framing mask.
Advantage of the present utility model is: at first, the fixture of rat is in strict accordance with the status requirement design of animal in centrifuge, prevents that rat from taking the protectiveness position, so that farthest observe the behavior state performance of rat when G-LOC takes place; The second, can gather the preservation video again by observing the behavior state of animal in centrifuge judge the generation of animal G-LOC intuitively in real time, so that further playback analysis afterwards; The 3rd, animal model success rate height, the good stability of the simulation G-LOC that sets up by this method, the pathophysiological mechanism and the prophylactico-therapeutic measures that cause brain damage for research positive acceleration provide stable basis.
