Abstract
A breath-operated interface device having a disposable module and a base. The disposable module having a breath tube with an inlet. A first pressure differential switch is in pneumatic communication with the breath tube and configured to be actuated by a change in pressure in the breath tube. A first signal coupler of the disposable module is in electrical communication with the first pressure differential switch to receive a signal according to an actuation state of the first pressure differential switch. The device may also include a base with a second signal coupler, where the second signal coupler is configured to detachably electrically connect with the first signal coupler of the disposable module. The base also includes a station interconnect configured to interface with an external system, such as, for example, a nurse call system.
