Embodiment
The present invention will be further elaborated with reference to the accompanying drawings and examples, it should which explanation, the description below is only
It is to explain the present invention, its content is not defined.
As shown in Fig. 1 Fig. 2, the experimental animal of the embodiment of the present invention is included with breathing anesthesia outfit, including outer cover 1, anesthesia
Chamber 2, air inlet pipe 3 and muffler 4, and anesthesia source of the gas, the inner side of outer cover 1 is provided with pressure sensitive device, pressure sensitive device
Including bearing plate 5, spring 6, rheostat 7 and controller 8, outer cover 1 is that insulating materials is made with bearing plate 5.Bearing plate 5, bullet
Spring 6 and rheostat 7 include upper and lower bearing plate, upper lower spring and upper and lower rheostat.One end of spring 6 is fixed on the inwall of outer cover 1
On, the other end is connected with bearing plate 5, and the bottom surface of bearing plate 5 connection rheostat 7, rheostat 7 is connected with controller 8, controller 8
It is connected with anesthesia compressed air source unit, controller 8 can cut off anesthesia source of the gas in time, stop fiber crops according to the anesthesia of experiment mice
It is liquor-saturated.
The end of air inlet pipe 3 is provided with one-way vent valve 9, and anesthetic gases enters anesthesia chamber 2 by one-way vent valve 9
In, the gas anaesthetized in chamber 2 cannot be introduced into air inlet pipe, avoid cross-infection.
In order to prevent gas leakage, connection cloth 10 is sealed between bearing plate 5 and the inwall of outer cover 1.
In order to reach more preferable gas distribution effect evenly, the gas prevented from air inlet pipe 3 is directly entered the quilt of muffler 4
Drain, the front portion of outer cover 1 is provided with return-air chamber 11, and the inwall of return-air chamber 11, which is uniformly distributed along the circumference, is provided with stomata 12, and stomata 12 is communicated in
Anesthesia chamber 2 and return-air chamber 11, the outer wall of return-air chamber 11 are provided with gas returning port 13, and gas returning port 13 connects with muffler 4.Due to anaesthetizing gas
Body easily converges in anesthesia chamber 2 bottom, therefore gas returning port 13 and muffler 4 are arranged at into outer cover 1 than the gas weight that animal breathes out
Top, this design can make anesthetic gases anesthesia intracavitary extended residence time, improve anesthesia efficiency.
In order to prevent the rear port 14 of outer cover 1 poorly sealed, rear port 14 is provided with inlet shroud 15, inlet shroud 15 is bullet
Property material, the middle part of inlet shroud 15 is provided with entrance 16, is provided with inlet shroud 15 around entrance 16 and easily tears seam 17, entrance
