Description
Technical field
The invention provides a kind of hermetically sealed isolation toy mouth and nose and expose frame.
Background technology
Utilize in recent years some rats, mice, the toys such as Cavia porcellus suck experiment and study respiratory medications and pollutants in air is more and more paid attention to for anthropogenic influence's simulation experiment study and application, in laboratory, be mostly to adopt the cylindrical shape shelf that toy is put into special making to fix only to expose the mouth of toy and the method for nose positive alignment experimental gas breathing completes test, current existing special-purpose toy fixed mount adopts the rigid materials such as overall plastic material or lucite to be made mostly, although having facilitated animal fixes 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 toxic gas leakage meeting to pollute operator, or push rear toy and cannot activity cause dyspnea, slightly long toy of restriction time aches all over and just struggles and cause blood pressure, the rhythm of the heart, the endocrine regulations such as fervescence, some also can be dead in experimentation, even if there is netted flexible constraint frame newly developed, find that again interface is not easy sealing, still likely can produce certain Leakage Gas and affect test effect and environmental pollution, the result of the shortcoming severe jamming respiration test of these unsurmountable adverse consequencess, affected the development of this type of scientific research, become when last large technical barrier, so developing a kind of can not only can laying fast fixes toy and does not make its head have any Leakage Gas but also can allow toy suitable activity health once in experimentation, convert attitude, conveniently the breathing of expansion pulmonary is happy does not have temperature to accumulate, can be because of toy dyspnea, struggle causes blood pressure, the rhythm of the heart, in the endocrine regulations such as fervescence and experimentation dead adverse consequences not only can hermetically sealed isolation do not make poisonous gas leakage protect operator and environment simultaneously but also have the multiple functions such as animal environment ventilation humiture detection be integrated hermetically sealed isolation toy mouth and nose expose and put up as current urgent needs.
Summary of the invention
For addressing the above problem, the object of this invention is to provide a kind of hermetically sealed isolation toy mouth and nose and expose frame, adopting an inner flexible constraint frame is that main body fixes toy, externally surround a seal isolation cover structure with the rigidity of ambient parameter monitor and ventilating system, can both can lay fast and fix toy and do not make its head have any Leakage Gas, can allow toy suitable activity health once in experimentation, can be because of toy dyspnea, struggle causes blood pressure, the rhythm of the heart, the adverse consequences of death in the endocrine regulations such as fervescence and experimentation, not only can hermetically sealed isolation do not make poisonous gas leakage protect operator simultaneously but also have animal environment to ventilate and the multiple function such as ambient parameter detection, solved satisfactorily and met toy and suck experiment and study respiratory medications and pollutants in air for anthropogenic influence's simulation experiment study and application.
For achieving the above object, the technical solution used in the present invention is that flexible constraint net of employing and bottom bracket are that primary structure retrains fixedly toy, outside surround a hermetically sealed isolation cover structure with the rigidity of ambient parameter monitor and ventilating system and come the seal isolation experimental gas can be from internal leakage to peripheral operation space, bottom bracket front end is connecting the outer fixed interface that has inner air inlet pipe, the gas that can introduce respiration test flows into suction gas to toy is provided, outer fixed interface outside has a circle external tapping sealing ring to be fixed on specific breathing bulkhead, outer fixed interface inside is can discharge the mouth and nose exposure gas cabin of the expired gas discharge orifice of toy breath with a circle, mouth and nose expose inside, gas cabin can hold the lower toy snout air feed breathing of accepting respiration test, a flexible screen frame of semicircle with flexible constraint net can firmly be arranged on bottom bracket top, between bottom bracket and flexible screen frame, place toy, the cervical region bayonet socket of bottom bracket top is just in time applicable to the shape size of toy cervical region, the comfortable tight toy cervical region of fixing can not exit it, can not touch and guarantee that breathing gas can not leak, flexible constraint net can retrain toy trunk do not escape and can allow toy have certain body movement amount do not make its feel bad cause struggle irritable, toy tail passes from afterbody fixing hoop endoporus, toy Excreta leaks into dung collection box from bottom bracket back porus excretorius, the back of sealing joint circle is provided with an isolation cover interface with seal closure cushion rubber fixing hermetically sealed isolation cover is installed outside, hermetically sealed isolation cover front end top has an air outlet and by exhaust hose, gas is discharged, hermetically sealed isolation cover rear end has below a fresh air inlet and by air induction hose, fresh air outside gas is inputted to hermetically sealed isolation cover is inner by entering air interface, in center, hermetically sealed isolation cover rear end, have the opening installation environment parameter detection device with detector sealing ring, with ambient parameter detector, the environment of hermetically sealed isolation cover inside is monitored to guarantee the environmental requirement of toy necessity in experimentation.
The invention has the beneficial effects as follows that having developed a kind of hermetically sealed isolation toy mouth and nose exposes frame, adopting an inner flexible constraint frame is that main body fixes toy, externally surround a seal isolation cover structure with the rigidity of ambient parameter monitor and ventilating system, can both lay fast and fix toy and do not make its head have any Leakage Gas, can allow toy suitable activity health once in experimentation, convert attitude, conveniently the breathing of expansion pulmonary is happy does not have temperature to accumulate, can be because of toy dyspnea, struggle causes blood pressure, the rhythm of the heart, the adverse consequences of death in the endocrine regulations such as fervescence and experimentation, not only can hermetically sealed isolation do not make poisonous gas leakage protect operator simultaneously but also have animal environment to ventilate and the multiple function such as ambient parameter detection, the shortcoming and a large technical barrier that has affected the development of this type of scientific research of the adverse consequences of these severe jamming respiration test results have been solved satisfactorily, meeting toy sucks experiment and studies respiratory medications and pollutants in air for anthropogenic influence's simulation experiment study and the requirement of application.
