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:

an input device that receives a signal each time a heartbeat of a patient is detected, the input device being actuated by an end-user each time the patient'"'"'s heartbeat is auscultated;

a microprocessor coupled to the input device, wherein the microprocessor is programmed with one or more predetermined heartbeat thresholds and calculates the number of signals received by the input device based on the number of times the patient'"'"'s heartbeat is auscultated over a predetermined amount of time to generate a calculated heart rate; and

a display connected to the microprocessor that receives the calculated heart rate and outputs the calculated heart rate along with a unique identifier identifying which of the one or more predetermined heartbeat thresholds that the calculated heart rate resides within.

2. The device of claim 1, wherein the predetermined heartbeat thresholds comprise predefined ranges of a newborn'"'"'s heartbeats per minute.

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

4. The device of claim 1, wherein the input device is a component of a stethoscope.

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 display outputs a numerical output that comprises average heartbeats per minute, whereby the numerical output changes color depending on where the average heartbeats per minute fall within the one or more predetermined heartbeat thresholds.

7. The device of claim 1, wherein the one or more predetermined heartbeat thresholds are set at whether a patient has less than 60 heartbeats per minute, between 60 and 100 heartbeats per minute or greater than 100 heartbeats per minute.

8. The device of claim 1, wherein the display outputs a different signal output that comprises average heartbeats per minute, whereby the different signal output changes depending on which of the one or more predetermined heartbeat thresholds the average heartbeats per minute fall within.

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 predetermined heartbeat thresholds.

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

placing a stethoscope on a patient;

providing a device for inputting data each time a heartbeat of the patient is detected, the device comprising;

an input device that receives a signal each time a heartbeat of a patient is detected;

a microprocessor coupled to the input device, wherein the microprocessor is programmed with one or more predetermined heartbeat thresholds and calculates the number of signals received by the input device over a predetermined amount of time to generate a calculated heart rate; and

a display connected to the microprocessor that receives the calculated heart rate and outputs the calculated heart rate along with a unique identifier identifying which of the one or more predetermined heartbeat thresholds that the calculated heart rate resides within;

an end-user actuating the input device each time the patient'"'"'s heartbeat is auscultated to generate a number of heartbeat signals, the number of heartbeat signals being generated based on the number of times the patient'"'"'s heartbeat is auscultated;

inputting each of the number of heartbeat signals into the microprocessor;

calculating the heart rate in the microprocessor using the input number of heartbeat signals;

outputting the calculated heart rate to the display; and

treating the patient based on which of the one or more predetermined heartbeat thresholds that the calculated heart rate resides within.

11. The method of claim 10, wherein the predetermined heartbeat thresholds comprise predefined ranges of a neonatal patient'"'"'s heartbeats per minute.

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

13. The method of claim 10, wherein the display is updated with a rolling-average of heartbeats calculated at a select number of heartbeats.

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

15. The method of claim 10, wherein the display outputs a numerical output that comprises uniquely identified average heartbeats per minute, whereby the numerical output changes color depending on where the uniquely identified average heartbeats per minute fall within the one or more predetermined heartbeat thresholds.

16. The method of claim 10, wherein the one or more predetermined heartbeat thresholds are set at whether the patient has less than 60 heartbeats per minute, between 60 and 100 heartbeats per minute or greater than 100 heartbeats per minute.

17. The method of claim 10, wherein the display outputs a different signal output that comprises average heartbeats per minute, whereby the different signal output changes depending on which of the one or more predetermined heartbeat thresholds the average heartbeats per minute fall within.

18. 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 where the average heartbeats per minute fall within the predetermined heartbeat thresholds.

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

an input device, the input device being actuated each time a heartbeat of a patient is auscultated to generate actuation data;

a microprocessor coupled to the input device and receiving the actuation data from the input device, the microprocessor is programmed with predetermined heartbeat thresholds and calculates the number of times the input device is actuated using the input actuation data over a predetermined amount of time to generate a calculated heart rate;

a display connected to the microprocessor that receives the calculated heart rate and outputs the calculated heart rate along with a unique identifier identifying whether the calculated heart rate is below, at or above any of the predetermined heartbeat thresholds; and

treating the patient based on where the calculated heart rate falls within the predetermined heartbeat thresholds.
