Abstract

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.

First claim

What is claimed is:

1. A mouse handling system (MHS) for anesthetizing and accurately positioning a laboratory animal inside a magnetic resonance device (MRD) while preventing leakage of anesthetization gas and/or accidental spillage of hazardous materials to ambient atmosphere, the MHS comprising:
a distal portion that is insertable into said MRD, the distal portion comprises:
a) a cradle to accommodate said animal,
b) an anesthetization gas mask that can be adjustably placed relative to animal,
c) a gas inlet in fluid communication with the anesthetization gas mask and capable of being in fluid communication with a gas supply,
d) a gas outlet in fluid communication with the anesthetization gas mask and capable of being in fluid communication with an air suction outlet, and
e) an air tight shell to encapsulate the cradle, the anesthetization gas mask, the gas inlet and the gas outlet; and

a proximal portion positioned outside said MRD when the distal portion is within said MRD and a shaft, the proximal portion incrementally rotatable about and slidable along said shaft to translate and rotate the laboratory animal when the laboratory animal is positioned within said distal end and said distal end is within said MRD.

2. The system of claim 1 , wherein said shaft comprises indicia indicating the relative angular and translational position of said distal portion with respect to said MRD.

3. The system of claim 1 , further comprising a plurality of levers and handles for locking said angular and translational position.

4. The system of claim 1 , wherein said cradle comprises a heating/cooling mechanism.

5. The system 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 said housing.
