DEVICE HAVING A DIGITAL INFRARED SENSOR AND NON-TOUCH OPTICAL DETECTION OF OF VITAL SIGNS FROM A TEMPORAL VARIATION AMPLIFIER

摘要

A microprocessor is operably coupled to a camera from which patient vital signs are determined. A temporal variation of images from the camera is generated and amplified from which the patient vital sign, such as heart rate or respiratory rate, can be determined and displayed or stored.

主权项

1. A device comprising:
a microprocessor; a battery operably coupled to the microprocessor; a single button operably coupled to the microprocessor; a camera operably coupled to the microprocessor and providing at least two images to the microprocessor; a digital infrared sensor operably coupled to the microprocessor, the digital infrared sensor having ports that provide only digital readout; and a display device operably coupled to the microprocessor, wherein the microprocessor is operable to receive from the ports that provide only digital readout a digital signal that is representative of an infrared signal generated by the digital infrared sensor and the microprocessor is operable to determine a temperature from the digital signal that is representative of the infrared signal and the microprocessor including a cropper that is operable to receive at least two images from the camera and operable to crop the images to exclude a border area of the images, generating at least two cropped images, the microprocessor also including a temporal-variation-amplifier of at least two cropped images that is operable to generate a temporal variation, the microprocessor also including a vital-sign generator that is operably coupled to the temporal-variation-amplifier that is operable to generate at least one vital sign from the temporal variation and the microprocessor also operably coupled to the display device that is operable to display the at least one vital sign.
