Next, the auxiliary tools 1a and 1b of the present invention will be described. The auxiliary tools 1a and 1b are used to guide the puncture device 9 and / or the blood glucose measuring device 7 to a target site when the device is used. Hereinafter, the auxiliary tool 1a of the first embodiment and the auxiliary tool 1b of the second embodiment will be sequentially described.

As shown in FIG. 1, the assisting tool 1a is composed of a curved plate-shaped (plate-shaped) guide member 2 and a ring-shaped (annular) fixed member 3.

On one surface of the guide member 2, a guide surface 21 formed of a concave surface (curved concave surface) is formed. The puncture device 9 and the blood glucose measurement device 7 abut on the guide surface 21 and are guided to a predetermined position.

Since the guide surface 21 is concave, the puncture device 9
When the blood glucose measuring device 7 is guided, their lateral positions are also regulated (positioned) to some extent, which is preferable.

The curvature of the guide surface 21 having a curved concave surface is not particularly limited. For example, the guide surface 21 may have a radius of curvature of about 0.5 to 20 cm.

In the illustrated embodiment, the guide surface 21
Is a concave surface curved in a substantially arc shape, but is not limited thereto.
For example, it may be a U-shaped or V-shaped concave surface.

The outer peripheral portion of the fixed member 3 is fixed to the back side of the guide member 2 (the side opposite to the guide surface 21). The fixing member 3 is for holding a measurer's finger (particularly the thumb 14) therein to support and fix the assisting tool 1a (see FIGS. 5 and 6).

The fixing method of the guide member 2 and the fixing member 3 is as follows.
There is no particular limitation, and examples thereof include fusion (thermal fusion, ultrasonic fusion, and the like), adhesion with an adhesive, fitting, caulking, screwing, and the like. Further, the guide member 2 and the fixing member 3 may be formed integrally.

In the illustrated configuration, the fixing member 3 is formed by forming a plate piece into a ring shape, but the members constituting the fixing portion 3 are not limited to this, and may be, for example, a mesh (net-like body), a frame member, or the like. , A belt (band), a string, or the like.

The shape of the fixing member 3 is not limited to a ring shape as shown in the figure, but may be any shape as long as it can be fixed to a finger. For example, it may be a C-shaped member, a clip, or the like.

The auxiliary tool 1a can be used for both the puncture device 9 and the blood glucose measuring device 7. Thereby, the operation from puncturing the finger with the puncture device 9 to aspirating the blood 16 with the blood glucose measuring device 7 can be performed using the same auxiliary device 1a.
The operation can be performed without removing or replacing the finger from the finger to which it is fixed, so that the operation is extremely easy.

In the present invention, a dedicated auxiliary tool 1a for each of the puncture device 9 and the blood glucose measuring device 7 is prepared.
It does not prevent use.

As shown in FIG. 2, the auxiliary tool 1b includes a guide member 4 having a flat plate shape (a strip-shaped plate piece).

On one surface (upper surface) of the guide member 4, a guide surface 41 formed of a flat surface is formed. This guide surface 41
Then, the puncture device 9 and the blood glucose measuring device 7 come into contact with each other, and they are guided to a predetermined position.

In the illustrated embodiment, the guide surface 41 is used.
Is a flat surface, but may be a curved surface such as a curved concave surface, or a curved surface bent in a V-shape.

The proximal end 42 and the distal end 43 of the guide member 4
Each constitute a finger contact unit for contacting a finger. As shown in FIGS. 7 and 8, the thumb is applied to the base end 42 of the guide member 4 and the index finger is applied to the distal end 43 of the guide member 4, and the guide member 4 is gripped by these fingers.

On the guide surface 41 on the distal end side of the guide member 4,
When guiding the puncture device 9 and the blood glucose measuring device 7, a pair of ribs (convex stripes) 5 are installed as a positioning mechanism for regulating (positioning) the position in the lateral direction (the width direction of the guide member 4). .

The ribs 5 are arranged substantially symmetrically on the guide surface 41. Both ribs 5 are arranged in a tapered shape (C-shape) such that their gap distance gradually decreases toward the distal end (toward the target portion). When the puncture device 9 and the blood glucose measurement device 7 are moved from the proximal end toward the distal direction on the guide surface 41, the puncture device 9 and the blood glucose measurement device 7
Slides while abutting against the tapered surface 51 of any of the ribs 5, and its lateral position is automatically corrected. Thus, by the time the distal ends of the puncture device 9 and the blood glucose measuring device 7 approach the target position (the punctured site, the bleeding blood 16), the distal portions of the puncture device 9 and the blood glucose measuring device 7 That is, it is positioned substantially at the center in the width direction.

Claws (stoppers) 6 are formed at the ends of the ribs 5 respectively. This claw (stopper) 6
Has a function of contacting the shoulder 75 of the blood glucose measurement device 7 and defining the limit of access to the target site (bleeding blood 16) of the blood glucose measurement device 7.

That is, when the blood glucose measuring device 7 is moved in the distal direction along the guide member 4, the blood glucose measuring device 7 is guided by the guide surface 41, and the lateral position is also corrected by the ribs 5. When the blood glucose measuring device 7 is further moved in the distal direction, the shoulders 75 abut (engage) with the claws 6 of the ribs 5,
It can no longer move in the tip direction. At this time, the protrusion 8 of the tip 8 attached to the blood glucose measurement device 7
The tip of 2 reaches the target site, that is, contacts the blood 16. By providing the nail 6 in this way, the blood glucose measuring device 7 is prevented from moving more than necessary after reaching the target site.

The puncture device 9 may be provided with a stopper (a mechanism for preventing the tip of the puncture needle 94 from pressing a finger more than necessary) that exerts a similar function.

Further, such a stopper may be provided for the above-mentioned auxiliary tool 1a.

The method of fixing the rib 5 to the guide member 4 is as follows.
There is no particular limitation, and examples thereof include fusion (thermal fusion, ultrasonic fusion and the like), adhesion with an adhesive, screwing, and the like. Further, the guide member 4 and the rib 5 may be formed integrally.

Such an auxiliary tool 1b can be used for both the puncture device 9 and the blood glucose measuring device 7. Thereby, the operation from puncturing the finger with the puncture device 9 to aspirating the blood 16 with the blood glucose measuring device 7 can be performed using the same auxiliary device 1b. The puncture of the finger 15 by the puncture device 9 and the suction of the blood 16 by the blood glucose measuring device 7 can be performed while holding the thumb 14 and the other finger (index finger) 15 of the hand, so that both operations are easy and quick. Can be done. In addition, since both operations can be performed without once removing the assisting tool 1b from the hand, the puncture site of the finger 15 by the puncture needle 94 and the blood 16 bleeding therefrom become the same relative to the guide member 4, respectively. Therefore, when the blood 16 is aspirated, the blood 1
The position of the tip of the protruding portion 82 of the chip 8 with respect to 6 can be determined more accurately.

In the present invention, a dedicated auxiliary tool 1b for each of the puncture device 9 and the blood sugar measuring device 7 is prepared.
It does not prevent use.
