Abstract
An exciter-detector unit is disclosed which includes an exciter and a detector mounted on a common support for inducing perturbations into the body and detecting the perturbations after they travel a distance through the body in order to detect a hemoparameter.
Claims24
An exciter-detector unit for measuring physiological parameters of a patient comprising:
- a support member adapted to be placed on the patient, an exciter mounted on said support member for transmitting perturbations into the patient at a first location, and
- a detector mounted on said support member spaced a predetermined distance along the support member from said exciter for detecting a hemoparameter and to provide an output signal containing a component of a physiological parameter waveform and a component of received perturbations.
An exciter-detector unit for measuring physiological parameters at selected positions on the body of a patient comprising:
- an exciter for transmitting vibrations into the patient at a first location at said position, and
- a detector spaced from said exciter for detecting a hemoparameter at a second location to provide an output signal containing a component of a physiological parameter waveform and a component of received vibrations, and
- an elongated support member for supporting said exciter and detector at a predetermined fixed spacing along said elongated support member.
