Zusammenfassung: | A noninvasive method of sensing an arterial pulse on a paw pad includes providing an instrument having a probe; placing the probe housing a tactile transducer and a reflective optical coupler comprising an infrared emitter and an infrared detector on a subject's metatarsal or metacarpal pad; emitting infrared light from the emitter; detecting infrared light with the detector; maintaining a linear direct current bias of the detector; converting a signal emitted by the infrared detector into a digital pulse that drives the tactile transducer to emit tactile pulses; and counting the tactile pulses over a predetermined time. An arterial pulse detection system includes a probe. The probe contains an optical sensor and a tactile transducer to which instrumentation is electrically connected. The optical sensor includes an infrared emitter and an infrared detector. |
