23 Jul DEVICE FOR DETECTING PULSE SIGNALS
Abstract
FIELD: medical engineering. ^ SUBSTANCE: device has light-emitting element producing light passing through biological tissue to photosensitive cell connected to power supply source with one of its electrodes. Inductance element is also available. It is connected with one lead to the other electrode and threshold device input and with the other end to common buss. The device also has capacitor and resistor connected in parallel to the inductance element. The inductance element, capacitor and resistor form band-pass filter. ^ EFFECT: reduced pulse signal dependency on individual patient specific; stabilized photosensitive cell working point; improved noise immunity. ^ 1 dwg
