Sensor insertion/recovery device
First Claim
1. A sensor insertion and removing device, comprising:
- a sensor;
a puncture blade member;
a housing which houses the sensor and the puncture blade member;
a guide part which is provided within the housing and which glidibly supports the puncture blade member;
a puncture blade operating part including a first grip part which is fixed to a predetermined first basic portion in the puncture blade member, and inserted through an operation opening so as to be exposed outside the housing;
a sensor operating part including a second grip part which is fixed to a predetermined second basic portion in the sensor, and inserted through the operation opening so as to be exposed outside the housing;
wherein the puncture blade operating part delivers the puncture blade member integrally with the sensor towards the outside of the housing in coordination with the movement of the first grip part to a first direction with respect to the housing, and removes the puncture blade member into the housing in coordination with the movement of the first grip part to a second direction which is opposite the first direction, andthe sensor operating part delivers the sensor towards the outside of the housing in coordination with the movement of the second grip part driven by the movement of the first grip part to the first direction with respect to the housing, and removes the sensor into the housing in coordination with the movement of the second grip part to the second direction.

Abstract
The present invention provides a sensor insertion and removing device which is user-friendly and which does not cause infection. The sensor insertion and removing device has a sensor; a puncture blade member; a housing which houses the sensor and the puncture blade member; a guide part which is provided within the housing and which glidably supports the puncture blade member; a puncture blade operating part which inserts the sensor under the skin by causing the puncture blade member to glide along the guide part integrally with the sensor, upon delivering the puncture blade member outside the housing to puncture the skin, and which causes the puncture blade member to glide along the guide part in a state of being separated from the sensor, upon removing the puncture blade member from under the skin into the housing, and a sensor operating part which pulls out the sensor from under the skin and removes it from under the skin into the housing.

12. A sensor insertion and removing method, comprising the steps of:
-
a setup step of setting, on skin, a sensor insertion and removing device, which comprises a sensor;
a puncture blade member;
a housing which houses the sensor and the puncture blade member;
a guide part which is provided within the housing and which glidably supports the puncture blade member;
a puncture blade operating part including a first grip part which is fixed to a predetermined first basic portion in the puncture blade member, and inserted through an operation opening so as to be exposed outside the housing; and
a sensor operating part including a second grip part which is fixed to a predetermined second basic portion in the sensor, and inserted through the operation opening so as to be exposed outside the housing;a sensor insertion step of inserting, after the setup step, the sensor under the skin by causing the puncture blade member to glide along the guide part integrally with the sensor, upon delivering the puncture blade member outside the housing to puncture the skin in coordination with the movement of the first grip part to a first direction with respect to the housing; a puncture blade removing step of removing, after the sensor insertion step, the puncture blade member from under the skin into the housing by causing the puncture blade member to glide along the guide part in a state of being separated from the sensor in coordination with the movement of the first grip part to a second direction which is opposite to the first direction; and a sensor removing step of removing, after the puncture blade removing step, the sensor from under the skin into the housing by pulling the sensor out from under the skin in coordination with the movement of the second grip part to the second direction. - View Dependent Claims (13, 14)
