Abstract

The present invention includes devices, methods and systems for reporting a heart rate comprising: an input device; a microprocessor coupled to the input device and a power supply, wherein the microprocessor is programmed with a predetermined heartbeat threshold and calculates the number of times the input device is actuated over a predetermined amount of time; and a display connected to the microprocessor that receives the calculated heart rate and displays whether the heart rate is below, at or above predetermined threshold, e.g., when a patient has less than 60 heartbeats per minute, between 60 and 100 heartbeats per minute and greater than 100 heartbeats per minute.

Claims

1. A device for reporting a heart rate comprising:

a stethoscope having a manually actuated input device, the input device is a manually actuated by an end user of the stethoscope each time the end user detects a heartbeat of a newborn upon which the stethoscope is placed and generates a signal for each said manual actuation;

a microprocessor coupled to the input device, wherein the microprocessor is programmed with a first predetermined newborn heartbeat threshold having a first unique identifier, a second predetermined newborn heartbeat threshold having a second unique identifier, and a third predetermined newborn heartbeat threshold having a third unique identifier, the microprocessor including a central processing unit (CPU), a computer readable memory, a computer readable storage media, and a set of program instruction including,

first program instructions to receive the signals of each said manual actuation corresponding to each said detected heartbeat,

second program instructions to calculate a number of times the input device is actuated over an amount of time using the received signals,

third program instructions to generate a calculated heart rate based on the calculated number of times the input device is actuated,

fourth program instructions to determine whether the calculated heart rate resides within the first, second or third predetermined newborn heartbeat thresholds,

fifth program instructions to associate the corresponding first, second or third unique identifier to said calculated heart rate based on said determined threshold in which said calculated heart rate resides, thereby generating a uniquely identified calculated heart rate,

sixth program instructions to output said uniquely identified calculated heart rate,

wherein the first, second, third, fourth, fifth and sixth program instructions are all stored on the computer readable storage media for execution by the CPU via the computer readable memory; and

a display connected to the microprocessor that receives and displays the uniquely identified calculated heart rate at least to said end user thereby informing at least said end user of whether the calculated heart rate resides within the first, second or third predetermined newborn heartbeat threshold for performing any necessary medical action on the newborn.

2. The device of claim 1, wherein the manually actuated input device is permanently attached to the stethoscope.

3. The device of claim 1, wherein the display is activated once the input device has been actuated a predetermined number of times.

4. The device of claim 1, wherein the actuated amount of time is at least 0.1 seconds.

5. The device of claim 1, wherein the display outputs a numerical output that comprises uniquely identified average heartbeats per minute.

6. The device of claim 1, wherein the first, second and third unique identifiers are color coded indicators.

7. The device of claim 1, wherein the first predetermined newborn heartbeat threshold is set at less than 60 heartbeats per minute, the second predetermined newborn heartbeat threshold is set at between 60 and 100 heartbeats per minute, and the third predetermined newborn heartbeat threshold is set at greater than 100 heartbeats per minute.

8. The device of claim 1, wherein the manually actuated input device is actuated by the end user by thumb, finger, foot or other manual input.

9. The device of claim 1, wherein the display outputs a combination of a numerical output and a different signal output of average heartbeats per minute, whereby the numerical output and the different signal output change depending on where the average heartbeats per minute fall within the first, second or third predetermined heartbeat thresholds.

10. A method for calculating a neonatal heart rate comprising the steps of:

an end user placing a stethoscope on a newborn;

providing a manually actuated input device for inputting data each time a heartbeat is auscultated;

providing a microprocessor coupled to the input device, wherein the microprocessor is programmed with a first predetermined heartbeat threshold having a first unique identifier, a second predetermined newborn heartbeat threshold having a second unique identifier, and a third predetermined newborn heartbeat threshold having a third unique identifier;

the end user manually actuating the manually actuated input device each time the heartbeat is auscultated by said end user, thereby generating a signal for each said manual actuation that is input into the microprocessor;

using the input signals, the microprocessor calculating a number of times the manually actuated input device is actuated over an amount of time and generating a calculated heart rate based thereon;

the microprocessor determining whether the calculated heart rate resides within the first, second or third predetermined newborn heartbeat thresholds, and associating the corresponding first, second or third unique identifier to said calculated heart rate based on said threshold in which said calculated heart rate resides, thereby generating a uniquely identified calculated heart rate;

outputting the uniquely identified calculated heart rate to a display connected to the microprocessor;

displaying the uniquely identified calculated heart rate at least to said end user thereby informing at least said end user of whether the calculated heart rate resides within the first, second or third predetermined newborn heartbeat threshold; and

treating the newborn based on whether the uniquely identified calculated heart rate falls within the first, second or third predetermined newborn heartbeat threshold.

11. The method of claim 10, wherein the stethoscope is positioned on the newborn immediately after birth and the uniquely identified calculated heart is generated and output to a medical team present at the birth before any mechanically generated heart rate readings are provided to the medical team.

12. The method of claim 10, wherein the display is activated once the input device has been actuated a predetermined number of times.

13. The method of claim 10, wherein the actuated amount of time is at least 0.1 seconds.

14. The method of claim 10, wherein the manually actuated input device is permanently attached to the stethoscope.

15. The method of claim 10, wherein the display outputs a numerical output that comprises uniquely identified average heartbeats per minute.

16. The method of claim 10, wherein the first, second and third unique identifiers are color coded indicators.

17. The method of claim 10, wherein the first predetermined newborn heartbeat threshold is set at less than 60 heartbeats per minute, the second predetermined newborn heartbeat threshold is set at between 60 and 100 heartbeats per minute, and the third predetermined newborn heartbeat threshold is set at greater than 100 heartbeats per minute.

18. The method of claim 10, wherein the manually actuated input device is actuated by the end user by thumb, finger, foot or other manual input.

19. The method of claim 10, wherein the display outputs a combination of a numerical output and a different signal output of average heartbeats per minute, whereby the numerical output and the different signal output change depending on whether the average heartbeats per minute fall within the first, second or third predetermined newborn heartbeat thresholds.

20. A system for providing real-time medical information comprising:
