Method and assembly for a wireless probe and interrogator
A method and system for the wireless interrogation of a body immersed in a circulatory bath or a tank for heating. More specifically, the system may include a probe having multiple sensors for gauging a core temperature associated with the immersed body in combination with one or more wireless connections leading to a controller (on a circulator or a user interface) such that the user can determine temperature information (e.g., core temperature) of the body being immersed.
1 . A probe assembly disposed within a water bath for providing body temperature data to a remote interrogator and receiving power from the remote interrogator outside of water bath containing the body, the probe assembly comprising:
a rigid member having a first end, a second end, and a shaft extending therebetween;
a first sensor at the first end for providing temperature data related to the interior of the body;
a second sensor at the second end for providing temperature data related to the body;
a radio frequency transmitter at the second end of the rigid member for providing temperature data to a remote interrogator through the water bath;
a chip on the second end for receiving temperature data from the first sensor and the second sensor, the chip storing said temperature data to provide to the transmitter; and
an emitter, and a light harvester and capacitor on the second end for receiving the sole source of power from the remote interrogator for the chip and the emitter for transmitting an LED signal from the emitter to the remote interrogator.
2 . A probe assembly for providing temperature data corresponding to surface and interior temperatures for a body residing in a bath, and for enabling temperature data to be transmitted to remote interrogator, the probe assembly comprising:
a) a rigid member comprising a first end and a second end, and a shaft extending there between, the first end to be inserted into the body and the second end being outside the body;
b) a first sensor at the first end for receiving temperature data corresponding to the interior of the body;
c) a second sensor at the second end for receiving temperature data corresponding to the surface of the body;
d) an LED emitter at the second end for relaying temperature data received from the first sensor and the second sensor;
e) a chip on the second end for receiving temperature data from the first sensor and the second sensor, the chip storing said temperature data to provide to the LED emitter; and
f) a light harvester and capacitor on the second end for receiving the sole source of power for the chip and the LED emitter from an emitter on the remote interrogator.
3 . A probe and interrogator assembly for monitoring temperature data of at least the interior of a body in a bath, the assembly comprising:
a) an interrogator comprising:
i) a controller; and
ii) a transceiver, the transceiver including an antenna for receiving a signal from a probe assembly, the transceiver further including a light source for providing energy to the probe assembly;
b) the probe assembly for providing body temperature data to a remote interrogator outside of a bath containing the body, the probe assembly comprising:
i) a rigid member having a first end, a second end, and a shaft extending therebetween,
ii) a first sensor at the first end for providing temperature data related to the interior of the body;
iii) a radio frequency transmitter at the second end for relaying temperature data received by the first sensor and a second sensor;
iv) a chip on the second end for receiving temperature data from the first sensor and the second sensor, the chip storing said temperature data to provide to a light transmitter; and
v) a light harvester and capacitor on the second end for receiving power from the transceiver so as to provide the sole source of power for the chip and the light transmitter.
4 . The probe and interrogator assembly of claim 3 , wherein the interrogator further comprises a user interface for providing a display related to the temperature data to a user.
