The biosensor embedding device 1 according to the first embodiment of the present invention will be described below with reference to FIGS.
The biosensor 2 embedded in the body by the biosensor embedding device 1 according to the present embodiment is a sensor that measures biometric information such as a blood glucose level, for example. The biological information measured by the biological sensor 2 embedded under the skin is transmitted to a device outside the living body by wire or wirelessly.

As shown in FIG. 1, the biosensor embedding device 1 according to the present embodiment includes a mantle tube 3, an introduction needle 4 that is housed in the mantle tube 3 and holds the biosensor 2 at the tip, and a disinfectant A And a bag body (disinfecting means) 5 disposed at the tip of the outer tube 3.
The outer tube 3 has a cylindrical shape with both ends opened, and the distal end surface has a shape capable of sealing a gap with the skin when pressed against the skin surface, for example, a flat shape.

  The introduction needle 4 is disposed between the proximal end surface of the outer tube 3 via a spring 6 and is urged by the spring 6 in the proximal direction. Thus, the introduction needle 4 is disposed at the storage position shown in FIG. 1 where the tip is stored inside the tip surface of the outer tube 3 when not being operated by the user. When the user presses the proximal end of the introduction needle 4 against the biasing force of the spring 6, the distal end portion of the introduction needle 4 protrudes from the opening of the distal end surface of the outer tube 3 and punctures the skin. It is arranged at a possible puncture position.

  The biosensor 2 is held in the distal end portion of the introduction needle 4 by a frictional force with the inner peripheral surface of the introduction needle 4. In addition, a protrusion 4 a is provided inside the introduction needle 4 so as to protrude inward in the radial direction and abut against the surface on the proximal end side of the biosensor 2. The user presses the proximal end of the introduction needle 4. When the introduction needle 4 is moved to the distal end side, the biosensor 2 is also moved integrally with the introduction needle 4.

  The bag body 5 stores the disinfectant A and is disposed between the distal end of the introduction needle 4 disposed at the storage position and the distal end surface of the outer tube 3. The bag body 5 is easily cleaved by being punctured by the tip of the introduction needle 4 like a balloon, for example, and the disinfecting liquid A is leaked out. Thereby, when the introduction needle 4 moves from the storage position to the puncture position, the bag body 5 is cleaved to permit movement to the puncture position. That is, the puncture permission means of the present embodiment is configured by disposing the bag body 5 between the tip of the introduction needle 4 arranged at the storage position and the tip of the introduction needle 4 arranged at the puncture position. Has been.

The usage method and operation of the biosensor embedding device 1 configured as described above will be described below.
In order to embed the biosensor 2 under the skin of the living body using the biosensor embedding device 1 according to the present embodiment, the distal end surface of the outer tube 3 is pressed against the surface of the skin B above the position where the biosensor 2 is to be embedded, The distal end surface and the skin B are sufficiently adhered (see FIG. 2A). In this state, the proximal end of the introduction needle 4 is pressed. Thereby, the bag body 5 is cleaved by the tip of the introduction needle 4, and the disinfectant A leaked from the bag body 5 is stored in a space formed by the surface of the skin B and the inner surface of the outer tube 3 (FIG. 2B). )reference.). Thereby, the area | region enclosed by the outer tube 3 of the skin B is disinfected.

  Then, by further pressing the introduction needle 4, the introduction needle 4 is passed through the disinfecting liquid A and the introduction needle 4 is moved to the puncture position, thereby puncturing the skin B (FIG. 2C). reference.). Thereafter, the introduction needle 4 is released from the pressure and pulled out from the skin B. At this time, the biosensor 2 is left subcutaneously without moving together with the outer tube 3 due to the frictional resistance generated between the subcutaneous tissues (see FIG. 2D).

  Thus, according to the present embodiment, the disinfecting liquid A is sprayed on the skin B in the process of the operation in which the introduction needle 4 is punctured into the skin B. Thereby, immediately before the introduction needle 4 is punctured into the skin B, the skin B is sterilized by the antiseptic solution A, and there is an advantage that the cleanability of the skin B when the biosensor 2 is implanted subcutaneously can be ensured. . In addition, since both the disinfection of the skin B and the puncture of the skin B with the introduction needle 4 are sequentially performed by a one-step operation of pressing the introduction needle 4, the patient himself / herself operates the biosensor embedding device 1 However, the skin B and the introduction needle 4 can be sterilized simply and reliably.
