Abstract

Methods for purposes such as obtaining information pertaining to human beings or other animals having body cavities wherein fluids from which desired information can be derived are at least temporarily present. A means for collecting a body fluid is introduced into the body cavity and left therein for a time sufficient to provide for collection of a quantity of fluid suitable, for example, for subsequent analysis. The fluid collected by the collecting means is enclosed in an enclosure which can then be transmitted to a laboratory or the like for subsequent analysis of the fluid.

Claims

1. In a method for obtaining information pertaining to human beings or other animals having body cavities wherein fluids from which the desired information can be derived are at least temporarily present, the steps of situating at a body cavity a means responding to presence of a fluid at the body cavity for collecting the fluid, leaving the latter means at the body cavity for a length of time sufficient to provide for collection of a quantity of fluids suitable for subsequent analysis, enclosing the collected fluid while said means remains in the body cavity in an enclosure suitable for transmittal to a laboratory or the like where the collected fluid is to be analyzed, while preventing the collected fluid in said enclosure from flowing out of said enclosure, and then analyzing the body fluid to obtain the desired information.

2. In a method as recited in claim 1 and wherein an enclosure having an entrance through which fluid enters the enclosure is situated at the body cavity with said entrance forming the means for collecting the body fluid while the remainder of the enclosure serves to enclose the collected fluid in the body cavity.

3. In a method as recited in claim 1, said enclosure having an entrance through which fluid enters the enclosure, and including the step of closing said entrance after a suitable quantity of the body fluid has been collected in said enclosure.

4. In a method as recited in claim 3 and wherein the closing step in manually performed.

5. In a method as recited in claim 3 and wherein the closing step is automatically performed.

6. In a method as recited in claim 1 and wherein the means situated at the body cavity to collect the body fluid is in the form of a unit capable of absorbing a body fluid by capillary action.

7. In a method as recited in claim 6 and wherein the enclosure for enclosing the body fluid is situated at the body cavity together with said unit with the latter extending partly into the enclosure.

8. In a method as recited in claim 7 and wherein said unit is compressible to squeeze body fluid therefrom while said enclosure is at least in part flexible at a portion surrounding said unit between a part thereof situated outside of the enclosure and a part thereof situated within the enclosure, and including the steps of contracting the flexible part of the enclosure to squeeze the unit at the part thereof which extends through the contracted enclosure part, and while maintaining the flexible part of the enclosure in its contracted condition withdrawing the unit from the enclosure to squeeze the fluid out of the unit into the enclosure.

9. In a method as recited in claim 6 and wherein said unit extends only partly into the container so that the fluid drips from the unit into the container in a hollow portion thereof situated beyond the unit.

10. In a method as recited in claim 1 and wherein said agent is a preservative applied to the collected body fluid prior to analysis of the body fluid.

11. In a method as recited in claim 10 and wherein the preservative is an antibiotic.

12. In a method as recited in claim 10 and wherein a part of the body fluid which is to be analyzed is extracted from the body fluid prior to said analysis.

13. In a method as recited in claim 12 and wherein the extracted part of the body fluid is diluted in a suitable solution prior to analysis.

14. In a method as recited in claim 1 and wherein the body cavity is the vagina and the collected fluid is menstrual blood.

15. In a method as recited in claim 14 and wherein the menstrual blood is diluted with water to precipitate red blood cells therefrom.

16. In a method as recited in claim 15 and wherein the solution remaining after precipitation of the red blood cells from the menstrual blood is tested for presence of uterine cancer cells and other cells of the female reproductive tract.

17. In a method as recited in claim 16 and wherein the matter suspended in the solution after precipitation of the red blood cells is separated from the solution and is then tested for the presence of uterine cancer cells and other cells of the female reproductive tract.

18. In a method as recited in claim 1 and including the step of situating in the enclosure said agent which will give the collected fluid a predetermined condition.

19. In a method as recited in claim 1 and including the step of applying part of the collected fluid to a growth medium situated in the enclosure, so that growth of bacteria or the like in the fluid can go forward even during transmittal of the enclosure to the laboratory or the like for subsequent analysis.

22. In a method as recited in claim 1 and wherein the means for collecting the body fluid is a tampon and the body cavity being a vagina into which the tampon is introduced for collecting vaginal fluid, and the enclosure being outside of the body and including the step of transferring fluid from the tampon to the enclosure for transmittal therein to a laboratory or the like.

23. In a method as recited in claim 22 and wherein a preservative is also introduced into the enclosure.

24. In a method as recited in claim 23 and wherein the enclosure is provided with suitable identification of the individual from whom the fluid is derived.

25. In a method as recited in claim 24 and wherein the material in the enclosure is subjected to treatments such as agitation, exposure to ultrasonic waves, centrifuging, or the like.

20. In a method for obtaining information pertaining to human beings or other aminals having body cavities wherein fluids from which the desired information can be derived are at least temporarily present, the steps of situating at a body cavity a means for collecting a body fluid present at the cavity, leaving the latter means at the body cavity for a length of time sufficient to provide for collection of a quantity of the fluid suitable for subsequent analysis, enclosing the thus-collected fluid in an enclosure suitable for transmittal to a laboratory or the like where the collected fluid is to be analyzed, and then analyzing the body fluid to obtain the desired information, and including the step of automatically closing the enclosure after a suitable quantity of fluid has been collected therein and simultaneously with the closing step releasing to the interior of the enclosure an agent which will contact the fluid collected therein to give the fluid a predetermined condition.

21. In a method as recited in claim 20 and wherein the released agent is a broth for promoting the growth of bacteria in the collected fluid.
