Patient monitoring apparatus and method
First Claim
1. Apparatus for use in monitoring a patient'"'"'s respiration, comprisingdisposable flexible substrate means, including a flexible inductive respiration signal transducer, for maintaining the flexible respiration signal transducer coupled with a patient to produce a signal representing the patient'"'"'s respiration;
- a wireless telemetry device for transmitting a respiration signal to a wireless receiver; and
manually releasable coupling means for manually detachably coupling the wireless telemetry device with said transducer for transmitting a respiration signal produced thereby whereby the telemetry device can be selectively coupled and decoupled with the transducer without damaging the coupling;
said disposable means including a non-replaceable power source mounted within the substrate for supplying operating power to said wireless telemetry device; and
said coupling means including means for selectively and manually detachably coupling said power source means to said wireless telemetry device.

Abstract
A respiration transducer apparatus for monitoring respiratory movement in patients is disclosed which includes a transducer for detecting respiratory movement in the patient'"'"'s body. The transducer includes a first inductor adapted to be positioned adjacent a portion of the patient'"'"'s body and a second inductor adapted to be positioned adjacent the same portion of the body. The transducers are disposed in a substantially fixed geometric relation as an integrally fixed coil with the first and second inductors inductively reacting with each other and a forming a continuous transducing area.
