Abstract

Apparatus 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 situated proximate to the body cavity and left there 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 an apparatus for obtaining from a female body fluid, such as vaginal fluid, information pertaining to female human beings or other female animals, collecting means for automatically collecting a body fluid when in contact with the same, said collecting means being capable of remaining comfortably in juxtaposition to a body cavity, such as the vagina, for a time sufficient for collecting a body fluid, such as vaginal fluid, in an amount sufficient for analysis, enclosure means for enclosing the collected fluid for transmittal to a laboratory or the like where the collected fluid is to be analyzed, said enclosure means having an interior with which said collecting means communicates, means for causing said body fluid to flow from the collecting means to the enclosure means while substantially avoiding flow of the collected fluid by way of the collecting means back to the body cavity, and closure means operatively connected to said enclosure means for closing said enclosure means not later than upon removal of the same from the body cavity so as to prevent contamination of body fluid in the enclosure means.

2. The combination of claim 1 and wherein an agent such as a preservative is situated in said enclosure means for cooperating with the collected fluid to give a desired characteristic to the latter.

3. In an apparatus 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, collecting means for automatically collecting a body fluid when said collecting means is situated in juxtaposition to a body cavity where the fluid is present, enclosure means for enclosing the collected fluid for transmittal to a laboratory or the like where the collected fluid is to be analyzed, said collecting means and enclosure means being provided with means for causing flow of the fluid from the collecting means to the enclosure means while substantially avoiding flow of the collected fluid by way of the collecting means back to the body cavity, said collecting means operating by capillary action to automatically collect fluid in the body cavity, said collecting means being in the form of a unit such as a wad of filamentary material, and said enclosure means including a container into which said collecting means partly extends for delivering collected fluid thereto, and closure means operatively connected to said enclosure means for closing said enclosure means not later than upon removal of the same from the body cavity so as to prevent contamination of body fluid in the enclosure means.

4. In an apparatus 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, collecting means for automatically collecting a body fluid when said collecting means is situated in juxtaposition to a body cavity where the fluid is present, and enclosure means for enclosing the collected fluid for transmittal to a laboratory or the like where the collected fluid is to be analyzed, said collecting means and enclosure means being provided with means for causing flow of the fluid from the collecting means to the enclosure means while substantially avoiding flow of the collected fluid by way of the collecting means back to the body cavity, said collecting means including an elongated wick adapted to automatically suck body fluid from an end of the wick in engagement with the body fluid along the length of the wick, said enclosure means including an elongated enclosure formed with an opening through which the wick extends into the interior of the enclosure, trigger means in the enclosure for automatically retracting the wick into the interior of the enclosure after the enclosure and wick have remained in juxtaposition to the body cavity for a time sufficient to afford collection of a suitable quantity of fluid by the wick, means responding to operation of the trigger means to retract the wick into the enclosure for automatically placing in engagement with the fluid collected by the wick an agent which affects the fluid, and closure means operatively connected to said enclosure means for closing said enclosure means not later than upon removal of the same from the body cavity so as to prevent contamination of body fluid in the enclosure means.

5. The combination of claim 4 and wherein a closure means is operatively connected with said trigger means to be actuated thereby for automatically closing said opening to the exterior of the enclosure.

6. The combination of claim 4 and wherein said trigger means has a temperature-responsive component which in response to the temperature of the body cavity responds to cause the trigger means to retract the wick after the enclosure and wick have been at the body cavity for a length of time sufficient for collection of a suitable quantity of the fluid.
