Abstract
A pressure-actuated floor mat, mattress or chair pressure sensor is enclosed within a flexible protective envelope that is provided with active electronic devices that can monitor the state of the sensor but which can also wirelessly transmit signals carrying information from the sensor-detecting electronics. Radio signals carrying information about the sensor are transduced or emitted from a small antenna within, or attached to the one of the envelopes surfaces. A receiver receives the signals emitted from the antenna and relays the information to a remote patient monitoring system is realized by the electronics and sensor within a disposable protective envelope.
Claims22
A mattress or chair sensor (sensor) comprised of:
- a flexible dielectric envelope that defines an interior volume and which includes therein, a sensor to detect a person on a mattress or a chair;
- and
- a single, substantially planar, elongated plastic substrate (substrate) having first and second opposing sides, the substrate being within the interior volume of the dielectric envelope and being sized, shaped and arranged to prevent the single plastic substrate and from being driven into a mattress or chair pad by the weight of a person to be monitored;
- a processor within the interior volume of the envelope;
- a radio frequency transmitter within the interior volume and electrically coupled to the processor;
- and
- an antenna within said interior volume and electrically coupled to the radio frequency transmitter, radio frequency signals broadcast from the antenna carrying sensor-generated information.
A sensor comprised of:
- a flexible plastic dielectric envelope (envelope) having an exterior surface and an interior surface, the envelope defining an interior volume, which includes first and second substantially rectangular conductive panels separated from each other by a non-conductive pliable gasket, the gasket and panels being configured to define a plurality of open area between the panels wherein gasket material surrounds each open area;
- a circuit board within envelope, the circuit board having at least one electronic device mounted thereon;
- a radio frequency transmitter mounted to the circuit board and generating radio frequency signals;
- and
- an antenna coupled to the radio frequency transmitter within the envelope, signals broadcast from the antenna carrying sensor-generated information.
