Pressure switches, transmitters, systems, and methods for monitoring a pressure at a tissue site
First Claim
1. A system for monitoring a pressure exerted on a tissue site, the system comprising:
- a transmitter operable to propagate a first signal, the first signal being a radio frequency signal, and emitting an alert when the transmitter receives a second signal in response to the first signal; and
a pressure switch adapted for placement adjacent the tissue site and to be responsive to a force applied at the tissue site, the pressure switch comprising;
an antenna operable to receive the first signal and propagate the second signal;
a diode disposed adjacent the antenna and electrically connected to the antenna to rectify the second signal;
a switch electrically connected to the antenna and the diode for completing a circuit when closed; and
a membrane covering the antenna and the diode, the membrane movable from an unpressed position to a pressed position when the force is exerted on the membrane to close the switch;
whereby the antenna propagates the second signal when the membrane is in the pressed position.

Abstract
Apparatuses, systems, and methods for monitoring a pressure exerted on a tissue site are provided. In one embodiment, an apparatus includes a pressure switch adapted for placement adjacent the tissue site. The pressure switch includes an antenna operable to receive a first signal, a diode disposed adjacent the antenna, and a membrane covering the antenna and the diode. The membrane is movable from an unpressed position to a pressed position when a force is exerted on the membrane to cause electrical communication between the antenna and the diode. The antenna is operable to send a second signal when the membrane is in the pressed position. The apparatus may also include a transmitter operable to emit the first signal to the antenna. The transmitter may output an alert when the transmitter receives the second signal.
