Description
Technical field
The invention provides a kind of toy mouth and nose and expose flexible constraint frame.
Background technology
Utilize some rats in recent years, mice, the toys such as Cavia porcellus carry out respiration test and obtain flourish to study respiratory medications and pollutants in air for the simulation experiment study of anthropogenic influence and application, these type of toy respiration test great majority of current experiment only can bundle toy with sebific duct or rope and simple being enclosed within by breathing mask on its nose arrives atomising device by hose connection, toy does not have good fixing means, sometimes the tight toy that affects tied is breathed and normal physiological limits, sometimes phenomenons such as tightly can not causing that midway is escaped is bundled, breathing mask is revealed and is not sternly caused the inaccurate of respiration test and contaminated environment, not smooth sometimes can also the causing of pipeline breathes anoxia impact experiment, some special toy fixed mounts carrying out respiration test use are had mostly to adopt the rigid material such as ail-plastic materials or lucite to be made recently, although facilitate animal to fix and respiration test, but the fixed mount that this type of rigid material is made is when fixing toy or push and sternly do not cause Head gas to leak, or push rear toy and activity cannot cause dyspnea, restriction time slightly long toy aches all over just to struggle and causes blood pressure, the rhythm of the heart, the endocrine regulations such as body temperature rising, some also can be dead in experimentation, the result of the shortcoming severe jamming respiration test of these unsurmountable employing firm constraints toy adverse consequencess, have impact on the development of this type of scientific research, become when last large technical barrier, so exploitation one not only can be laid fast and be fixed toy and do not make its head have any Leakage Gas but also can allow toy suitable movable lower body in experimentation, convert attitude, the breathing of convenient expansion pulmonary is happy does not have temperature to accumulate, also would not because of toy dyspnea, struggle causes blood pressure, the rhythm of the heart, the special toy mouth and nose of adverse consequences dead in the endocrine regulations such as body temperature rising and experimentation expose flexible constraint and put up as current urgent needs.
Summary of the invention
For solving the problem, the object of this invention is to provide a kind of toy mouth and nose and exposing flexible constraint frame, toy can be fixed fast, do not allow Leakage Gas can allow again the adverse consequencess such as the comfortable apnea difficulty of toy, struggle.
For achieving the above object, the technical solution used in the present invention is to provide a bottom bracket, extenal fixation interface and flexible screen frame, the gas that the extenal fixation interface that bottom bracket front end connects inner air inlet pipe can introduce respiration test flows into and provides suction gas to toy, extenal fixation interface internal is the mouth and nose exposure gas cabin with a circle exhalation pore, mouth and nose expose the toy head air feed accepting respiration test under inside, gas cabin can hold and breathe, one circle external tapping sealing ring of extenal fixation interface outside can be fixed on specific breathing bulkhead, the edge of bottom bracket both sides is respectively provided with two outstanding gim pegs, a flexible screen frame of semicircle with flexible constraint net can firmly be arranged on bottom bracket top by the holddown groove be fixed on base, toy can be placed between bottom bracket and flexible screen frame, fixing hole clipping on the cervical region fixing hoop of bottom bracket and flexible net upper frame edge is just in time applicable to the shape size of toy cervical region, the comfortable cervical region fixing toy tightly makes it exit, disorderly can not move and ensure that breathing gas can not leak, flexible constraint net on flexible screen frame can retrain toy trunk, make that toy is not escaped and health can have certain activity not make it feel bad, the tail of toy can pass from the afterbody fixing hole in afterbody fixing hoop, toy Excreta can be leaked into from bottom bracket back porus excretorius and is fixed on the dung collection box of bottom bracket bottom by box gim peg.
The invention has the beneficial effects as follows that developing a kind of toy mouth and nose exposes flexible constraint frame, not only can lay fast and fix toy and do not make its head have any Leakage Gas but also can allow toy suitable movable lower body in experimentation, convert attitude, the breathing of convenient expansion pulmonary is happy does not have temperature to accumulate, also would not because of toy dyspnea, struggle causes blood pressure, the rhythm of the heart, adverse consequences dead in the endocrine regulations such as body temperature rising and experimentation, special toy mouth and nose exposure flexible constraint frame is provided for satisfactorily completing toy respiration test, ensure that the result of respiration test is accurately rigorous, facilitate the development of this type of scientific research, be used widely in respiratory disease pathology and drug development scientific research.
