Description
Technical field
The present invention relates to a kind of zoopery instruments, and noninvasive ultrasound is carried out to mouse more particularly in a kind of mouse experiment
Fixed anaesthesia breathing mask when diagnosis for being anaesthetized to mouse.
Background technology
Noninvasive ultrasonic diagnostic technique is widely used in zoopery, is usually equipped with volatile anesthetic and is worked, i.e.,
Mouse is first positioned in anesthesia box after progress induced anesthesia before starting and is transferred quickly on operation panel by experiment, by mouse head
It is positioned over air passage nozzle and is continually fed into the maintenance anesthesia of mixed anesthesia gas.Noninvasive ultrasound is proceeded by after fixing mouse four limbs
Diagnostic operation.
In noninvasive Ultrasonic Diagnosis operating process, the physiological function of mouse can be inhibited due to excessively anaesthetizing, so to ensure
Experimental data accuracy needs suitably to adjust anesthesia amount, makes it from entering the deep anaesthesia shape for influencing experimental result
State.But it is Open architecture now to commonly use airway tube, and mouse head is only positioned over air passage nozzle and is continually fed by technician
Mixed anesthesia gas maintains anesthesia.And volatile anesthetic is adjusting anesthesia amount with the characteristic revived rapidly is anaesthetized rapidly
When be easy to cause mouse revival, head flee from ventilation nozzle lose anesthetic effect, also needed when necessary by mouse Departure operation panel
It is replaced in induced anesthesia in anesthesia box, experiment is seriously affected and carries out.
Operating process is also easy to cause stimulation to cause to revive mouse, and technician is when adjusting ultrasonic probe easily by mouse
Attack causes experiment accident to occur.And after mouse revives, technician controls mouse head and returns the salty new anesthesia of airway tube
When, mouse ultrasonic position can also deviate caused by manual operation is acutely revolted, and influence experimental implementation and result accuracy.
