Sensor insertion device and method for operating said device

摘要

A sensor inserting device includes a device main body and a push handle for moving a detector of a sensor and an insertion needle, with the sensor held coupled to the insertion needle, into the body of a patient. A transmitter, for processing a signal from the sensor, is set in the device main body. A cable, allowing transmission of a signal between the sensor and the transmitter, is connected to the sensor (12) and the transmitter.

1. A method for determining the state of a sensor comprising:
a processor of a display unit receiving a first signal from a transmitter, in communication with the sensor, wherein the first signal is received before the sensor is inserted into a patient; the processor retrieving a first threshold, wherein the first threshold is associated with a normal state for the sensor before the sensor is inserted into the patient; the processor comparing the first signal to the first threshold to determine if the sensor is in the normal state; if the first signal is not in the normal state, the processor:
determining that the sensor is not functioning properly; andproviding an alarm alerting that the sensor is not function properly if the first signal is in the normal state, the processor determining that the sensor is functioning properly; after insertion of the sensor:
receiving, by the processor, a second signal;retrieving, by the processor, a second threshold, wherein the second threshold is associated with a second normal state for the sensor after the sensor has been inserted into the patient, and wherein the first threshold and the second threshold are different;the processor comparing the second signal to the second threshold to determine if the sensor is in the second normal state;if the second signal is not in the second normal state, the processor:
determining that the sensor is not functioning properly;providing a second alarm alerting that the sensor is not function properly; andif the second signal is in the second normal state, the processor determining that the sensor is functioning properly.
