1. A sensor inserting device comprising:
- a device main body comprises a signal transmitting part;
a movement mechanism provided in the device main body and configured to move a detector of a sensor and an insertion needle, while in a held state, the sensor is held together with the insertion needle for piercing a body of a person to be measured, wherein the sensor is electrically connected to the signal transmitting part; and
a signal processor configured to be attached to and detached from the device main body and electrically connected to the signal transmitting part, wherein a signal, associated with biological information, produced by the sensor is transmitted through the signal transmitting part to the signal processor, and wherein the signal transmitting part transmits a signal between the sensor and the signal processor when the signal processor is attached to the device main body in the held state of the movement mechanism, wherein the signal transmitting part is a flexible cable that electrically connects the sensor to the signal processor when in the held state, moves with the sensor during sensor insertion, and maintains the electrical connection while the sensor is indwelling.

Abstract
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.
