Abstract

A probe used to determine different possible body conditions of a human or animal subject includes an elongated insertable portion which is adapted for use orally, anally or vaginally, and along which are provided a number of biosensors and/or temperature sensors. The elongated portion is contoured so as to have a complementary shape to the physiology of the user'"'"'s mouth, anus or vagina to ensure good contact between the probe sensors and the subject'"'"'s body fluids or tissues. At least some of the sensors are positioned within a channel or trough which extends along the insertable portion of the probe and which is sized to collect body fluids from the subject therein. Preferably the channel is defined by a pair of spaced apart projecting ribs with fluid grooves formed in the elongated portion to assist in directing body fluids towards the channel and sensors. In use, once the probe is inserted, body fluids will tend to collect in the channel ensuring that the sensors therein are emersed in the fluid, eliminating air pockets and ensuring more accurate biosensor readings.

Claims

1. A probe for determining a body condition of a human or animal subject comprising,

a generally cylindrical housing, the housing being elongated along a longitudinal axis and having a first end portion sized for insertion into the subject'"'"'s mouth, vagina or anus, and a second end portion,

the first end portion including an end tip having a first thickness, and a contoured portion spaced rearwardly from said end tip towards the second end portion, the contoured portion defined at least in part by a generally concave surface, said concave surface curving in a generally longitudinally extending arc with said contoured portion having a minimum thickness selected less than the first thickness,

at least one sensor disposed along said concave surface for sensing a body characteristic of said subject which is indicative of said body condition and generating data signals representative of said sensed body characteristic,

said contoured portion further including a pair of spaced apart ribs extending longitudinally along at least part of said concave surface to define a channel therebetween, said at least one sensor being disposed within said channel,

an integrated circuit for receiving said data signals from each of said sensors and for processing said data signals, and

an output electronically linked to said integrated circuit for outputting information representing the status of said body characteristic.

2. A probe as claimed in claim 1 wherein a plurality of sensors are axially spaced from each other along said concave surface, and said probe further comprising an ultrasonic sensor located at a forwardmost end of said end tip, said ultrasonic sensor being electronically linked to said integrated circuit.

3. A probe as claimed in claim 1 wherein a plurality of sensors are axially aligned with each other along said concave surface.

4. A probe as claimed in claim 1 further including a basal body temperature sensor, said basal body temperature sensor disposed along a portion of said first end portion radially spaced from said concave surface.

5. A probe as claimed in claim 3 wherein said body characteristic is selected from the group consisting of body temperature, pH level, Luteinising hormone level, mucous density, vaginal cavity pressure, estrogen level, progesterone level, and human chorionic gonadotrophin hormone level.

6. A probe as claimed in claim 5 wherein said output comprises a LCD display located in the second end portion of said housing for visually outputting said information.

7. A probe as claimed in claim 2 wherein, said sensors are disposed at axially spaced locations along said channel.

8. A probe as claimed in claim 7, wherein said first end portion further includes at least one groove extending in a genarally axial direction across said end tip substantially to said channel.

9. A probe as claimed in claim 1 wherein said subject is an animal, and said probe further includes a transponder signal receiver for receiving and identifying a signal from an animal transponder signal transmitter.

10. A vaginal probe for determining a body condition of a human subject comprising,

a housing elongated along a longitudinal axis and having a first end portion and a second end portion,

the first end portion having an end tip and a contoured portion spaced rearwardly from said end tip towards the second end portion, the first end portion being sized to permit its insertion into the subject'"'"'s vagina with said end tip locating adjacent to the subject'"'"'s cervix,

the contoured portion including a generally concave surface curving in a generally longitudinally extending arc,

a plurality of axially spaced sensors disposed along said concave surface, at least one of said sensors for sensing a body characteristic which is indicative of said body condition and generating data signals representative of said sensed body characteristic,

said contoured portion further including a pair of ribs, said ribs being spaced from each other and extending longitudinally along at least part of said concave surface to define a channel therebetween, said sensors being disposed at axially spaced locations along said channel,

an integrated circuit for receiving data signals from said sensors and for processing said data signals received therefrom, and

an output display electronically linked to said integrated circuit displaying information indicative of said body condition.

11. A probe as claimed in claim 10, wherein said first end portion fuher includes at least one groove extending in a generally axial direction across said end tip substantially to said channel.

12. A probe as claimed in claim 11, wherein said sensors are selectively operable independently from each other depending on the body characteristic to be sensed.

13. A probe as claimed in claim 12, wherein said body characteristic is selected from the group consisting of body temperature, pH level, Luteinising hormone level, mucous density, estrogen level, progesterone level, and human chorionic gonadotrophin hormone level.

14. A probe as claimed in claim 10, further including a basal body temperature sensor, said basal body temperature sensor disposed along a portion of said first end portion radially spaced from said concave surface.

15. A probe as claimed in claim 14, wherein said sensors comprise at least one biosensor for sensing covalent immubilization of haptens, polypeptides, enzymes, antibodies and DNA fragments, and said probe further includes an ultrasonic sensor disposed towards a forwardmost end of said end tip, said ultrasonic sensor electronically linked to said integrated circuit.

16. A vaginal probe for determining a body condition of a human or animal subject comprising,

a housing having a first end portion elongated along a longitudinal axis and sized for insertion into the subject'"'"'s vagina, and a second end portion,

the first end portion including a channel sized to permit the collection of vaginal fluids therein, and at least one sensor located within said channel for sensing a body characteristic of said subject which is indicative of a body condition and generating data signals representative of said sensed body characteristic,

an integrated circuit electronically linked to said at least one sensor for processing generated data signals, and

an output linked to said integrated circuit for outputting information indicative of said body characteristic.

17. A vaginal probe as claimed in claim 16, wherein said channel is defined in part by a pair of spaced apart longitudinally extending ribs, each of said ribs projecting radially outwardly from an immediately adjacent portion of said housing.

18. A vaginal probe as claimed in claim 16, wherein said first end portion further includes at least one fluid flow groove extending in a generally axial direction to assist in the flow of said vaginal fluids into said channel.
