FIELD: medicine.
SUBSTANCE: invention refers to medicine. A portable device for the noncontact random check of patient's vital values comprises: a distance sensor for series detection of a time range of the patient's chest, a respiratory rate calculator for respiratory activity measurement derived from the detected time range. Besides, the device comprises two handles so that the patient holds the device with both hands so that the distance sensor is directed to the patient's chest. The handles comprise ECG recording electrodes. The device comprises an optic sensor for photoplethysmographic measurement which is placed so that the patient holding the device automatically puts a finger on the optic sensor.
EFFECT: invention provides higher usability and simplicity of the random check of the patient's respiration ensured by guiding the distance sensor onto the patient's chest with two hands.
