Mask for analyzed mammals

摘要

An encapsulatable life support mechanism (ELSM) for an analyzed animal, including: a cradle or bed adapted by means of size and shape to accommodate the animal; an anesthetization gas mask (AGM) characterized by a cup with conic cross section, comprising a plurality of apertures located at the outer circumference of the cup; a fluid supplying mechanism (FSM) in which the AGM is placed, the FSM is in a continuous fluid communication with (i) an anesthetization gas inlet positioned outside the ELSM and an outlet located within the ELSM; (ii) an air suction scavenging device positioned outside the ELSM and a mask and an air suction outlet located within the ELSM; and a plurality of (iii) air conditioning tubes; and an airtight shell enveloping the same. The airtight ELSM prevent leakage of anesthetization gas.

1. An encapsulatable life support mechanism (ELSM) for an analyzed animal, comprising:
a. a cradle or bed selected to be of size and shape to accommodate said animal; b. an anesthetization gas mask (AGM) comprising: a hollow, generally cone-shaped main piece comprising a wide portion, a narrow end and an interior space; said narrow end comprising an orifice having a diameter; said wide portion comprising a central opening surrounded by a ring, said ring having an inner circumference forming said central opening and an outer circumference in physical connection with a single internal circumference of said generally cone-shaped main piece, said single internal circumference in the wide portion of said generally cone-shaped main piece; said ring comprising a plurality of apertures providing direct fluid connection between said interior space and points external to said generally cone-shaped main piece; c. a fluid supplying mechanism (FSM) in which said AGM is placed, said FSM in continuous fluid communication with (i) an anesthetization gas inlet positioned outside said ELSM and an outlet located within said ELSM; (ii) an air suction scavenging device positioned outside said ELSM and said mask, and an air suction outlet located within said ELSM; and (iii) a plurality of air conditioning tubes; and d. an airtight shell enveloping said ELSM, said airtight shell adapted to (i) prevent leakage of anesthetization gas from said ELSM outward to a laboratory; and (ii) avoid accidental spillage of hazardous materials from said airtight ELSM to said laboratory, wherein said airtight shell is adapted to provide thermal isolation between ambient air in said laboratory and air-conditioned animal environment, wherein, when a mammal's head is positioned in said central opening, said apertures, said interior space and said orifice comprise a direct open fluid connection between said external points, said interior of said mask, and points external to said narrow end, and wherein said orifice comprises a Bernoulli-type orifice.
