A wireless patient monitoring apparatus uses an optical signal to transmit information from a transducer to a photodetector of an optical receiver. The photodetector converts the optical signal to an electrical signal which is then provided to monitoring and analysis instrumentation. Signals which are indicative of physiological functions are modulated onto a carrier, and the resulting modulated signal is provided, in turn, to the optical source, which may be a light-emitting diode (LED) which emits in the infrared band. A self-contained portable transducer assembly which is strapped or otherwise secured to the patient may house the transducer, modulator and optical source, and is adapted for underwater use. Optionally, the optical source can be positioned remote from the assembly. In a fetal monitor implementation, both wireless ultrasound and tocodynamometer transducers are provided.
An optical patient monitoring apparatus, comprising:
A receiver for use with an optical patient monitoring system, said system including a transducer which is designed for placement on a patient to be monitored, said receiver comprising;
An optical source holder for use with a patient monitoring system, said system including a housing which provides a modulated signal carrying physiological information from a patient, wherein:
A method for performing underwater monitoring on a patient, comprising the steps of:
