Mask for analyzed mammals

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.

2. The AGM of claim 1 , wherein said mask is made of MRI-compatible materials, said MRI-compatible materials being selected from a group consisting of polymers.

3. The AGM of claim 1 , further comprising a mask maneuvering mechanism comprising an adjustment rod in connection with said mask, said adjustment rod adapted to ensure that said mask is located in a predefined location within a housing of said FSM.

4. The ELSM according to claim 1 , wherein said ELMS is an MRI-compatible ELSM.

5. The ELSM according to claim 4 , wherein said AGM, said FSM and mechanisms thereof are selected to be of a size and a shape to ensure anesthetization of animals, said animals selected from a group consisting of laboratory animals.

6. The ELSM according to claim 1 , wherein said AGM, said FSM and mechanisms thereof are selected to be of a size and a shape to ensure anesthetization of animals, said animals selected from a group consisting of laboratory animals.

7. The AGM of claim 1 , further comprising a mask maneuvering mechanism that includes an adjustment rod placeable within said interior of said mask, the diameter of said adjustment rod being smaller than said diameter of said adjustment rod, said adjustment rod locatable in at least one predefined location within said FSM.

8. A safe method for preventing leakage of anesthetization gas from gas supply inlets to a laboratory, comprising:

a. providing a cradle or bed selected to be of size and shape to accommodate said animal; 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 aperture 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; a fluid supplying mechanism (FSM), 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; an airtight shell, 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;

b. placing said AGM in fluid communication with said gas supply inlet;

c. placing said AGM in fluid communication with a suction gas outlet;

d. supplying anesthetization gas to said mask via said gas supply inlet; e. placing said AGM in said FSM; and f. enveloping said ELSM in said airtight shell;

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.
