Active on-patient sensor, method and system
First Claim
1. A patient monitoring system, comprising:
- (a) a low profile sensing apparatus, the low profile sensing apparatus including;
(i) a sensor for sensing a condition adjacent to a human body;
(ii) a signal processor coupled to the sensor for producing data based on the state of the condition adjacent to a human body sensed by the sensor;
(iii) a transmitter coupled to the signal processor for wirelessly transmitting a signal containing the data based on the state of the condition adjacent to a human body sensed by the sensor;
(iv) a power supply for supplying power to the sensor and the signal processor; and
(v) a low profile flexible printed circuit substrate, at least the signal processor, the transmitter, and the power supply mounted on the low profile flexible printed circuit substrate;
(b) a bedside monitor configured to;
(i) wirelessly receive the signal wirelessly transmitted by the transmitter of the low profile sensing apparatus containing the data based on the state of the condition adjacent to a human body sensed by the sensor; and
(ii) wirelessly transmit a signal containing the data based on the state of the condition adjacent to a human body sensed by the sensor; and
(c) a patient monitoring apparatus, the patient monitoring apparatus including;
(i) a receiver for receiving the signal wirelessly transmitted by the bedside monitor containing the data based on the state of the condition adjacent to a human body sensed by the sensor; and
(ii) a computing device for determining if the data based on the state of the condition adjacent to a human body sensed by the sensor is in-range or out-of-range.

Abstract
A sensor (which could be detachable) to sense a condition (including pressure from body weight or moisture from incontinence; applied by adhering to skin of a human body or by putting a diaper on the human body, for example), a signal processing circuit, a periodic or continuous transmitter, and a power supply (typically including a battery) are associated with a flexible substrate in low profile enabling disposition adjacent the human body. A transmitter antenna is on the substrate. Insulator film between battery contacts and a switch-and-transistor combination are two power-on techniques. A bedside monitor, a transceiver configured to receive signals from and transmit signals to the bedside monitor, and a computer connected with the transceiver can be included. Other features include: notification signaling; differently responsive antennas; unique identification; low battery detection; anti-collision transmission; patient protocol scheduling; local data transfer from the bedside monitor; and out-of-range transmission detection.
