Barcode scanning device for determining a physiological quantity of a patient
First Claim
1. A barcode scanning device configured both for reading a barcode attached to a patient and for determining a physiological quantity of the patient wherein the physiological quantity of the patient comprises at least one of a respiratory frequency of the patient or a pulse frequency of the patient, the barcode scanning device comprising:
- a light emitting unit configured for emitting light towards a surface to be sensed of the patient, wherein a wavelength of the emitted light comprises visible light or infrared light, and wherein the emitted light comprises a light pattern of at least one of a rectangular shape, a rectangular framed shape, a grid shape, and a spot shape,a light receiving unit configured for;
(i) receiving light reflected from a surface to be sensed of the patient, and(ii) acquiring images based on the received light, anda signal processing unit configured for;
(i) reading a barcode, and (ii) determining the physiological quantity of the patient based on the received light, wherein the signal processing unit comprises;
(i) a change signal determining unit configured for determining a signal indicative of a change between the images acquired based on the received light, and(ii) a peak detector configured for determining a peak of the signal indicative of the change between the acquired images.

13. A method of determining at least one of a respiratory frequency of a patient or a pulse frequency of the patient with a single device, the method comprising:
-
emitting light towards a surface of the patent to be sensed, wherein the emitted light comprises a light pattern of at least one of a rectangular shape, a rectangular framed shape, a grid shape, and a spot shape, receiving light reflected from the surface of the patent to be sensed by a light receiving unit of a barcode scanning device, acquiring images based on the received light, determining at least one of the respiratory frequency or the pulse frequency of the patient based on the received light by a signal processing unit of the barcode scanning device, determining a signal indicative of a change between images acquired based on the received light, and determining a peak of the signal indicative of the change between the images.
