Abstract

Provided herein is a self-contained physiological measuring device adapted for disposition within a patient body cavity, primarily the vagina, for an extended period of time (e.g., 6-48 hours or more). While disposed within the body cavity, the device periodically measures one or more physiological parameters. In addition to measuring such physiological parameters, the device is operative to store such measurements to memory for subsequent download/processing upon removal of the device from the body cavity and/or upon wireless interrogation.

Claims

1. A self contained physiological monitoring device adapted for disposition within a body cavity, comprising:

a body adapted for insertion into a body cavity;

a battery mounted to the body;

a memory device mounted to the body;

at least one sensor mounted proximate to the body, the sensor being operatively interconnected to the battery and the memory device, wherein the sensor is operative to monitor at least one physiological parameter and generate an output indicative of the physiological parameter, wherein the output is stored by the memory device; and

a bio-inert coating covering at least a portion of the battery, the memory and the sensor, wherein the bio-inert coating substantially isolates these elements from bodily fluids when disposed within a body cavity.

2. The device of claim 1, wherein the body comprises an annular ring.

3. The device of claim 2, wherein the annular ring comprises a vaginal diaphragm.

4. The device of claim 1, wherein the body is cylindrical.

7. The device of claim 4, wherein the control circuit comprises a microprocessor.

8. The device of claim 1, wherein the sensor comprises at least one of:

a temperature sensor;

a pH sensor;

a strain gauge;

a pulse oximetry sensor.

9. The device of claim 1, wherein said sensor comprises a strain gauge, wherein said strain gauge is spaced from the surface of said body.

12. The device of claim 5, further comprising:

a wireless interface operatively connected to the control circuitry, wherein the wireless interface is at least operative to transmit data from the memory device.

10. A self-contained intra-vaginal monitoring device, comprising:

an annular body;

a battery mounted to the body;

a memory device mounted to the body;

at least one strain gauge mounted proximate to the body, the strain gauge being operatively interconnected to the battery and the memory device, wherein the strain gauge generates measurement outputs, wherein the measurement outputs are stored by the memory device;

control circuitry mounted to the body and being operatively connected to the battery, memory and strain gauge, wherein the control circuitry controls the operation of the strain gauge and

a bio-inert elastic coating that substantially isolates the body, memory device, control circuit and strain gauge from bodily fluid.

11. The device of claim 10, further comprising:

a pulse oximetry sensor mounted to the body, the pulse oximetry sensor having at least first and second light sources and at least one light detector, wherein the control circuit drives the light sources and the light detector generates outputs, wherein said output is stored by the memory.

13. A method for generating diagnostic markers associated with hypogonadism in women, comprising:

obtaining, from a plurality of individuals, a plurality of measurements of intra-vaginal physiological parameters, wherein said measurements are taken over an extended monitoring period;

for each individual, associating said parameter measurements with a corresponding level of a measured hormone;

analyzing said parameter measurements and corresponding hormone levels to identify a relationship between at least one physiological parameter and said hormone.

14. The method of claim 13, further comprising;

using different hormone levels of different individuals to generate a base line reference for said measured hormone, wherein said base line reference is based on at least one of said plurality of measurements.

15. The method of claim 13, wherein said method comprises taking intra-vaginal measurements using of at least one of:

a temperature sensor;

a pH sensor;

a strain gauge; and

a pulse oximetry sensor.

16. The method of claim 13, wherein obtaining comprises using self-contained monitoring devices adapted for intra-vaginal insertion to take said measurements.
