Abstract
A biological information detection device includes: a needle body configured to pierce the living body; and a sensor that has an elongated shape and is configured to detect biological information using a distal end portion of the sensor that is configured to indwell inside a living body. The distal end portion of the sensor is insertable into the living body by moving along the needle body after the needle body has pierced the living body.
Claims14
A biological information detection device comprising:
- a needle body configured to pierce the living body;
- a sensor that has an elongated shape and that includes:
- a proximal end portion that is movable in a direction different from an extending direction of the needle body, and
- a distal end portion that is insertable into the living body by moving along the needle body after the needle body has pierced the living body, and that is configured to indwell inside the living body,
- wherein the sensor is configured to detect biological information using the distal end portion;
- an end member that is fixed to the proximal end portion of the sensor and that has a first cylindrical outer peripheral surface, wherein the end member is configured to pass a signal obtained from the sensor therethrough, the signal containing information indicative of a concentration of an analyte to be detected;
- a base member that is affixable to a surface of the living body;
- an end member guide path that is located in the base member and that has a cylindrical inner peripheral surface, wherein the end member guide path is configured to accommodate and guide the end member;
- and
- a detector configured to receive the signal from the end member, and to detect the concentration of the analyte to be detected based on the received signal, wherein the detector is attachable to and detachable from the base member and comprises:
- an insertion tube portion having a second cylindrical outer peripheral surface, the insertion tube portion being insertable into the end member guide path, and
- an operation portion that is integrally rotatable with the insertion tube portion,
- wherein the end member is configured to rotate as the end member is pushed and moved by the detector, and
- wherein the distal end portion of the sensor is configured to move along the needle body as the end member is pushed and moved by the detector,
- wherein the inner peripheral surface of the end member guide path and the second cylindrical outer peripheral surface of the insertion tube portion are connectable via a screw portion that is configured to move the insertion tube portion in a depth direction of the end member guide path in accordance with a rotational operation of the operation portion, and
- wherein a distal end surface of the insertion tube portion and a proximal end surface of the end member are connectable via a fitting portion that inhibits mutual rotation.

A biological information detection device comprising:
- a needle body configured to pierce the living body;
- a puncturing needle holding member that holds the needle body;
- a puncturing biasing member that provides a biasing force to the puncturing needle holding member toward the surface of the living body;
- a puncturing movable portion that is engaged with the puncturing needle holding member to hold a state in which the puncturing needle holding member receives the biasing force from the puncturing biasing member;
- a sensor that has an elongated shape and that includes:
- a proximal end portion that is movable in a direction different from an extending direction of the needle body, and
- a distal end portion that is insertable into the living body by moving along the needle body after the needle body has pierced the living body, and that is configured to indwell inside the living body,
- wherein the sensor is configured to detect biological information using the distal end portion;
- an end member that is fixed to the proximal end portion of the sensor and that is configured to pass a signal obtained from the sensor therethrough, the signal containing information indicative of a concentration of an analyte to be detected;
- a base member that is affixable to a surface of the living body;
- an end member guide path that is located in the base member and is configured to guide the end member;
- and
- a detector configured to receive the signal from the end member, and to detect the concentration of the analyte to be detected based on the received signal, wherein the detector is attachable to and detachable from the base member,
- wherein the distal end portion of the sensor is configured to move along the needle body when the end member is pushed and moved by the detector,
- wherein the puncturing movable portion is configured to be released from engagement with the puncturing needle holding member by being pushed by the detector, and thereby cause the needle body to pierce the living body, as the detector is moved with respect to the base member, and
- wherein the distal end portion of the sensor is configured to move along the needle body as the end member is pushed and moved by the detector.

- a removing biasing member that provides a biasing force to the removing needle holding member in a direction away from the surface of the living body;
- a removing movable portion that is engaged with the removing needle holding member to hold a state in which the removing needle holding member receives the biasing force from the removing biasing member;
- a sensor that has an elongated shape and that includes:
- a proximal end portion that is movable in a direction different from an extending direction of the needle body, and
- a distal end portion that is insertable into the living body by moving along the needle body after the needle body has pierced the living body, and that is configured to indwell inside the living body,
- wherein the sensor is configured to detect biological information using the distal end portion;
- an end member that is fixed to the proximal end portion of the sensor and that is configured to pass a signal obtained from the sensor therethrough, the signal containing information indicative of a concentration of an analyte to be detected;
