Abstract

The monitoring device incorporates transducing devices for converting the desired measured parameters into electrical signals capable of being processed by a local computer or microprocessor system. The device interacts with the ambulatory patient and then, via a modem or other electronic communication device, transmits the measured parameters to a computer located at a remote site. At the remote location the various indicia of the ambulatory patient'"'"'s condition are monitored and analyzed by the medical professional caregiver. To provide the ambulatory patient with an added level of convenience and ease of use, such monitoring device is contained in a single integrated package.

Claims

1. An apparatus for monitoring an ambulatory patient and establishing communication to a caregiver regarding the wellness parameters of such an ambulatory patient, such apparatus comprising:

a physiological parameter transducing device, said device generating an electronic signal representative of the value of the physiological parameter being monitored;

a central processor device, said central processor operatively coupled to said parameter transducing device and processing said physiological parameter electronic signals;

an electronic receiver/transmitter communication device, said communication device having one end operatively coupled to said processor and another end operatively coupled to a communication network;

an output device operatively coupled to said processor and providing a series of queries to the ambulatory patient, each query in the series is representative of a symptom the ambulatory patient may be experiencing;

an input device operatively coupled to said processor and configured to receive inputs from the ambulatory patient in response to the series of queries output by the output device, wherein the processor receives the electronic signal generated by the transducing device and inputs from the input device wherein each input from the input device is assigned a score representing the severity of the symptom and the scores are tallied at a remote location where if the tallied score exceeds a predetermined value, an exception is issued notifying a remote healthcare professional that the ambulatory patient requires immediate attention wherein said devices are integrated into a single unit.

2. The apparatus according to claim 1 wherein said integrated unit comprises:

a base, said base including said physiological parameter transducing device;

a housing, said housing including said central processor device, said electronic receiver/transmitter communication device, said input device and said output device; and

a support member, said support member having a first end connected to said base and a second end connected to said housing.

3. The apparatus according to claim 2, wherein said support member is rigid.

4. The apparatus according to claim 2, wherein said support member is adjustable.

5. The apparatus according to claim 2, wherein said support member is flexible.

6. The apparatus according to claim 2 wherein said support member is telescopic.

7. The apparatus according to claim 2 wherein said support member includes a hinge so that the apparatus can be folded.

8. The apparatus according to claim 2 wherein the first end of the support member is removably inserted into a socket in the base.

9. The apparatus according to claim 2 wherein the support member includes a first piece and a second piece wherein a first end of the first piece is coupled to the second piece by a first hinge and a second end of the first piece is coupled to the base by a second hinge so that when not in use, the apparatus can be folded for easy storage.

10. The apparatus according to claim 1 wherein the physiological parameter transducing device is a scale for monitoring the body weight of a chronic heart failure patient.

11. The apparatus according to claim 10 wherein said scale comprises:

a top plate defining an interior and exterior surface;

a base plate defining an interior and exterior surface;

a load cell having a top and bottom side and a first and second end disposed between said top plate and said base plate, wherein the top side of the first end of said load cell is in contact with a first support surface within the interior surface of said top plate, and the bottom side of the second end of said load cell is in contact with a second support surface within the interior surface of said base plate.

12. The apparatus according to claim 11 wherein said load cell further comprises a strain gage disposed on said load cell.

13. The apparatus according to claim 10 further comprising means for determining whether said patient requires hospitalization or medication adjustments based on said body weight.

14. The apparatus according to claim 6 wherein the scale is accurately operable on a hard floor as well as a carpeted floor.

15. The apparatus according to claim 10 wherein the scale has a standard of deviation ranging from about 0.04 to about 0.17.

16. The apparatus according to claim 10 wherein the scale has a standard of deviation ranging from about 0.04 to about 0.08.
