Imager for medical device
View Patent ↗A system for transmitting a temperature of a patient to an electronic medical record associated with the patient includes a thermometer with a digital display that is configured to display a temperature value associated with the temperature signal and at least one error-checking value. The system also includes a handheld imaging device including a camera to capture an image of the digital display of the thermometer, a processor to extract the text in the image using optical character recognition, and perform an error-check on the temperature value using the at least one error-checking value in the image, and to transmit the patient's identification number and temperature to an electronic medical record system.
1. A handheld imaging device, comprising:
a housing;
a camera supported by the housing and configured to capture a visual image containing text displayed by a thermometer, the text displayed by the thermometer including both a value representing a physiological measurement and a checksum value;
a processor operatively coupled to the camera and configured to:
extract the text from the visual image using optical character recognition, and
compare the value representing the physiological measurement and the checksum value to check for errors in the optical character recognition of the image;
a display on the housing configured to display the text; and
a network connection unit operatively coupled to the processor,
wherein the network connection unit is configured to communicate with an electronic medical record system and to transmit at least some of the extracted text to the electronic medical record system, and
wherein the processor is further configured to provide at least one of a message to capture a new visual image or an error message on the display screen, if the imaging device is not able to read, process or verify the value representing the physiological measurement.
2. The handheld imaging device of claim 1 , wherein the error-control includes using an error detection function to verify an integrity of the value representing the physiological measurement.
3. The handheld imaging device of claim 1 , wherein the error-control includes using an error correction function to correct error of the value representing the physiological measurement.
4. The handheld imaging device of claim 1 , wherein the camera is configured to image a temperature reading provided by a thermometer.
5. The handheld imaging device of claim 1 , further comprising:
a code interpretation module configured to interpret any one of the following in the image: a barcode or a quick response code.
6. The handheld imaging device of claim 1 , wherein the network connection unit communicates with the electronic medical system wirelessly.
7. The handheld imaging device of claim 1 , wherein the housing is a key fob.
