Abstract

A hand-held pediatric medical diagnostic device includes a sensor module adapted to detect one or more corresponding conditions of a child. A gel material at least partially coats a contact surface on the diagnostic device. The area of the contact surface and the weight associated therewith are selected to substantially stabilize the sensor module during use. In one version, the pediatric device comprises a pediatric respiratory rate sensing device in which an accelerometer is connected to a portable, rechargeable power source.

Claims

1. A portable, pediatric respiratory rate sensing device comprising:

an accelerometer adapted to detect respiration of a child;

a contact surface operatively connected to the accelerometer, the contact surface adapted to be placed in operative contact with the child'"'"'s chest;

a gel material at least partially coating the contact surface, the gel material selected from the group consisting of silicone, polyvinyl chloride, and latex; and

a portable, rechargeable power source electrically connected to the accelerometer;

wherein the area and weight associated with the contact surface, and the characteristics of the gel material, are selected to substantially stabilize the accelerometer during use to reduce spurious signals.

2. The device of claim 1, wherein the contact surface has an area about 4 square inches to about 14 square inches, a weight of about 130 to about 200 grams, and the gel material has an area substantially corresponding to the contact surface, a thickness of about ⅛

″

to ¼

″

, and a tackiness sufficient, under standard atmospheric conditions, to both adhere to the skin of the child being examined and be harmlessly removable therefrom.

3. The device of claim 1, further comprising a housing carrying the accelerometer, wherein the power source comprises a manually operable crank charger, the charger being selectively connectable to the housing.

4. The device of claim 1, wherein the device configured to sense respiratory rates in children from newborn infants to age five.

5. The device of claim 1, further comprising a control system for the device, the control system including a user interface and a processor suitably programmed to process input from the user interface and from the accelerometer.

6. The device of claim 5, wherein the control system is configured to operate the device in three modes consisting of infant, toddler, and child modes.

7. The device of claim 1, further comprising a transmitter operatively connected to the accelerometer to send signals corresponding to respiration detected by the accelerometer in a format selected from a group consisting of Bluetooth, Wi-Fi, NFC, radio, cellular, AM/FM, 802.5.14, and protocols of wireless diagnostic devices.

8. The device of claim 1, wherein the gel material comprises silicone configured to be peeled away from the contact surface and remain substantially intact, washable, and replaceable back on a corresponding contact surface for reuse.

9. The device of claim 1, further comprising:

a user interface module having user input areas to select respiratory programs and a screen for displaying corresponding readouts;

a first sensor module including the accelerometer, and a first power module including the rechargeable power source;

wherein the first power module and the first sensor module are user-detachable to enable attachment of a second power module and a second sensor module, said second modules being different from the first modules.

10. The device of claim 9, wherein the screen comprises a touch screen and at least some of the user input areas are available via the touch screen, the user interface module having a lower surface at least partially comprising the contact surface.

11. The device of claim 9, wherein the user input areas comprise selection buttons corresponding to respective modes of operation selected from the group consisting of infant, toddler, and child.

12. The device of claim 1, further comprising a temperature sensor, the temperature sensor operatively connected to the contact surface.

13. The device of claim 1, wherein the contact surface includes a pair of resiliently flexible straps for laying out on the child'"'"'s chest and wrapping around a wrist.

14. A hand-held pediatric medical diagnostic device, comprising:

a sensor module adapted to detect one or more corresponding medical conditions of a child;

a contact surface operatively connected to the sensor module, the contact surface adapted to be placed in operative contact with a child;

a control module including a user interface having user input areas to initiate at least one diagnostic program associated with the sensor module, and a processer suitably programmed to process input from the user interface and from the sensor module;

a portable, rechargeable power source electrically connected to the control module;

wherein the sensor module includes at least one sensor selected from the group consisting of an accelerometer, a thermometer, a galvanic sensor, a heart rate sensor, an oximeter, a stethoscope, a flow meter, an ECG/EKG sensor, an otoscope, and a photographic camera.

15. The device of claim 14, further comprising:

a gel material at least partially coating the contact surface, the gel material selected from the group consisting of silicone, polyvinyl chloride, and latex; and

wherein the area and weight associated with the contact surface, and the characteristics of the gel material, are selected to substantially stabilize the sensor module during use.

16. The device of claim 15, wherein the contact surface has an area about 10 square inches to about 14 square inches, a weight of about 130 grams to about 200 grams, and the gel material has an area substantially corresponding to the contact surface, a thickness of about ⅛

inch, and a tackiness sufficient, under standard atmospheric conditions, to both adhere to the skin of the child being examined and be harmlessly removable therefrom.

17. The device of claim 14, further comprising a housing carrying the control module, and wherein the power source comprises a manually operable crank charger, the charger selectively connectable to the housing.

18. The device of claim 14, further comprising a transmitter operatively connected to the control system to send signals corresponding to the medical condition detected by the sensor module in a format selected from the group consisting of Bluetooth, Wi-Fi, NFC, radio, cellular, AM/FM, 802.5.14, and protocols of wireless diagnostic devices.

19. The device of claim 14, further comprising a plurality of the sensor modules and a multiplexed sensor connector electrically connected to the control system, the connector adapted to removably receive any selected one of the sensor modules.
