Abstract

A preferred embodiment of a bio-medical cryogenic system 10 is described having a unique canister support frame 100. The frame 100 is elongated when in the upright position having side walls 102 and 104, a top wall 114, a bottom wall 118, a back wall 122 and internal dividers 132 forming a narrow elongated cavity subdivided into canister compartments 136 having a front opening 130. Upright abutment lips 121 and 138 are positioned in the compartments 136 to prevent canisters 50 from being inadvertently dislodged from the compartments 136. Access slots 150 are formed in the back wall 122 and at least one of the side walls 102,104 to enable a laboratory person to insert their finger into the slot and push a canister forward while the other hand is lifting a front portion of the canister above the abutment lip 121 or 138.

Claims

1. In a cryogenic system for storing bio-organic specimens at sub-zero temperatures in a cryogenic vessel, a cryogenic storage specimen frame for receiving and supporting one or more bio-organic specimen canisters, comprising:

elongated, normally upright, side walls extending between bottom ends and top ends;

a narrow top wall extending between the top ends of the side walls;

said top wall having a handle thereon to enable the frame to be carried upright;

a narrow bottom wall extending between the bottom ends of the side walls;

a narrow back wall extending between the side walls to partially enclose the frame defining an elongated narrow, normally upright, frame cavity having an elongated narrow front opening;

at least one frame divider extending between the side walls spaced from the top and bottom walls dividing the frame cavity into more than one normally vertically spaced compartments for receiving and supporting canisters therein; and

abutment means projecting into each compartment adjacent the front opening for preventing a canister from inadvertently being dislodged from the frame.

2. In the cryogenic system as defined in claim 1 wherein at least one of the side walls has finger slots formed therein to enable laboratory personnel to lift the canister above the abutment means and move the canister at least partially through the front opening.

3. In the cryogenic system as defined in claim 1 wherein the abutment means includes a lip formed on the dividers adjacent the front opening to prevent the canisters from being inadvertently dislodged from the frame.

4. In the cryogenic system as defined in claim 2 wherein the slots are formed in the back wall and extend partially toward the front opening providing access to a rear portion of the canister to enable the laboratory person to lift a canister bottom edge above abutment means with one hand and then push a rear edge of the canister forward with the other hand to move the canister at least partially outward through the front opening.

5. In the cryogenic system as defined in claim 1 wherein the back wail is formed by tabs formed integrally with the side walls that extend at substantially right angles from rear edges of the side walls.

6. In the cryogenic system as defined in claim 1 wherein the top wall is formed integrally with one side wall and the bottom wall is formed integrally with the other side wall.
