Abstract

A flexible sealed bag for containing and analyzing a specimen, comprising: an entrance; a first reservoir, communicating with the entrance, which receives specimen through the entrance; manually actuatable sealing means between the entrance and the reservoir; with a solid specimen, a liquid solvent in the reservoir into which the specimen becomes mixed; a narrow channel connecting the reservoir with an analysis chamber for permitting liquid in the reservoir to pass into the analysis chamber; the channel from reservoir to analysis chamber including manually actuatable sealing means for closing off the channel after adequate liquid has passed from the reservoir into the analysis chamber; the analysis chamber already holding a substance for reacting with the liquid transferred thereto; whereby a liquid specimen is divided into two parts, the part in the reservoir and the part in the analysis chamber.

Claims

2. The specimen analysis bag of claim 1, wherein said bag, said channel and said channel sealing means are comprised of such material and are so dimensioned that said bag may be readily severed at the vicinity of said channel sealing means to separate said reservoir from said reaction chamber.

3. The specimen analysis bag of claim 1 further comprising, reservoir sealing means between said reservoir and said bag entrance, said sealing means being actuatable to seal said reservoir, thereby preventing entry into and exit of material from said reservoir.

4. The specimen analysis bag of claim 3 further comprising, adhering means around said entrance for adhering said entrance to a source of specimen to permit gathering of specimen.

5. The specimen analysis bag of claim 1, wherein said bag is comprised of flexible material such that manipulating said bag displaces said bag and the material in it.

6. The specimen analysis bag of claim 5, wherein the substance with which the specimen is to react in said reaction chamber is stored in capsule means in said chamber;

said capsule means normally holding the substance so it is out of contact with specimen in said chamber;

said capsule means being operatable upon to cause release of the reaction substance from said capsule means such that the substance may react with the specimen in said chamber.

7. The specimen analysis bag of claim 1, wherein said reaction chamber is sub-divided into a plurality of separated chambers, each having within it a substance for reacting with specimen entering that said separate chamber;

all of said separate chambers communicating with said reservoir through a channel means;

said channel means including channel sealing means which may be actuated to seal each said separate chamber from said reservoir and from each other said separate chamber.

8. The specimen analysis bag of claim 7, wherein said separate chambers are each isolated from one another and each includes a separate channel communicating with said reservoir;

each said channel being provided with said sealing means.

9. The specimen analysis bag of claim 1, wherein the specimen is in solid form, said reservoir containing a receptacle holding solvent for the solid specimen, whereby when solvent exits from said receptacle, it dissolves the specimen.

10. The specimen analysis bag of claim 9, wherein said solvent receptacle is sealed and is adapted to be opened to permit solvent to exit therefrom by manipulation of said receptacle.

11. A method for performing at least two separate procedures on a specimen, including the steps of, placing a substance intended to react with the specimen in one section of a flexible bag;

placing a specimen in another section of the bag;

transferring a first portion of the specimen from the latter section to the former section of the bag;

sealing the bag in a manner which traps the first portion of the specimen in the one section of the bag;

further sealing the bag in a manner which traps the second portion of the specimen in the other section of the bag to be out of contact with the substance which is to react with the specimen so as to preserve the second portion for different use than the first portion;

operating upon the first section of the bag to bring about a reaction between the substance designed to react with the specimen and the first specimen portion.

12. The method for performing at least two separate procedures on a specimen of claim 11, including the additional step of severing the bag between the sealed section thereof in which the substance to react with the specimen is located and the other sealed section, thereby to form two separate sealed receptacles holding specimen.

13. The method for performing at least two separate procedures on a specimen of claim 11, wherein the specimen is a solid specimen and including the further steps of placing a solvent for the solid specimen in the other section of the bag prior to placing the specimen in that other bag section and dissolving the specimen in the solvent before transferring the specimen to the one section of the bag.
