Description

Technical Field

[0001] The utility model relates to the field of animal testing devices, in particular to a device used for animal gas anesthesia testing. Background Art

[0002] like Figure 1 As shown, the existing animal gas anesthesia test device passes the anesthetic pipe into the waste gas collection pipe to deliver gas anesthetic to the animal mask. Since the test animals cannot remain relatively quiet during the anesthesia process like humans, in order to facilitate the test, the test animals are usually tied to the fixed plate with tape; however, during the test, the test animals will still swing and struggle, and swing more significantly. Long-term swinging can easily cause cracks at the bifurcation of the anesthetic pipe and the waste gas collection pipe, resulting in anesthetic leakage, affecting the test effect. Utility Model Content

[0003] In response to the problems in the above-mentioned prior art, the present application proposes a device for animal gas anesthesia experiments, comprising a gas anesthesia pipeline and a fixed cover; wherein the gas anesthesia pipeline comprises a trumpet-shaped gas mask, a waste gas collection pipe and an anesthetic pipe; one end of the anesthetic pipe and the waste gas collection pipe is located inside the gas mask, in the same direction as the trumpet mouth of the gas mask, and the other end of the anesthetic pipe and the waste gas collection pipe extends outward from the tail of the gas mask; the fixed cover comprises an anesthetic pipe inlet, a waste gas collection pipe outlet and a double-tube fixed port, and the waste gas collection pipe outlet has a pipe structure extending in the same direction as the waste gas collection pipe.

[0004] Preferably, the double-tube fixing port adopts a double-hole structure, and each hole matches the anesthetic pipe and the waste gas collection pipe respectively.

[0005] Preferably, the double-tube fixing port adopts a single-hole structure, and the outer sides of the anesthetic pipeline and the waste gas collection pipeline are covered with double-hole sealing plugs, and the outer diameter of the double-hole sealing plugs matches the single hole of the double-tube fixing port.

[0006] Preferably, a hook is provided at one end of the anesthetic pipeline located inside the gas mask for fixing on the teeth of the animal.

[0007] Preferably, the gas mask, the waste gas collection pipe and the anesthetic pipe are integrally injection molded.

[0008] Preferably, the waste gas collection pipe and the anesthetic pipe have the same aperture and wall thickness.

[0009] Preferably, the inlet position and the outlet position of the anesthetic pipeline on the side wall of the fixed cover are located on the same straight line.

[0010] Preferably, the distance between the center line of the exhaust gas collecting pipe outlet and the inlet position of the exhaust gas collecting pipe on the side wall of the fixed cover is greater than 3 times the bending radius of the exhaust gas collecting pipe.

[0011] The above technical features can be combined in various suitable ways or replaced by equivalent technical features as long as the purpose of the utility model can be achieved.

[0012] Working principle: Before the animal gas anesthesia test begins, the animal needs to be fixed on the test bench, and the trumpet-shaped gas mask covers the animal's head. The gas anesthetic drug is delivered from the anesthetic pipeline to the gas mask until the desired anesthetic effect is achieved. The anesthetic drug that is not inhaled by the animal is delivered to the waste gas collection device through the waste gas collection pipeline (not shown in the figure).

[0013] The utility model provides a device for animal gas anesthesia test, which has at least the following beneficial effects compared with the prior art:

[0014] The relative swing between the internal parts of the animal gas anesthesia test device is reduced, the service life of the animal gas anesthesia test device is increased, the probability of failure is reduced, and the stability of the animal gas anesthesia test effect is improved.
