はソレノイド（２）と反対方向へ移動する。The adhesive sheet (8) of the needle storage part (7) is brought into contact with the applicable part of the skin. Avoid driving the solenoid drive device (a), and
A voltage is applied to the solenoid (2) as shown in Figure (3a). At this time, the iron core (3) of the solenoid (2) is magnetized to the same polarity as that of the permanent magnet (5), and the permanent magnet (5)
moves in the opposite direction to solenoid (2).
永久磁石（５）か移動すると同時に皮膚貫入用針（６）

イド（２）は、この交流電圧の電気的振動を磁気的振動
に変える。この磁気的振動は、永久磁石（５）に伝達さ
れ、永久磁石（５）は上下の機械的振動を行なう。Permanent magnet (5) moves at the same time as needle for skin penetration (6)
The skin penetrating needle (6) is also moved, and the skin piercing needle (6) is inserted into the skin tissue (I4) as shown in FIG. After insertion, use a skin-penetrating needle (6
) Blood flows along the surface and oozes into the blood pool (9). Furthermore, the solenoid drive circuit (a) applies an alternating current voltage as shown in FIG. 3 (3b) to the solenoid (2). The solenoid (2) converts the electrical oscillations of this alternating voltage into magnetic oscillations. This magnetic vibration is transmitted to the permanent magnet (5), and the permanent magnet (5) performs vertical mechanical vibration.
永久磁石（５）と同じく皮膚貫入用針（６）も振動し、
この振動は血液の凝固を阻止すると共に、鎮痛作用も生
じさける。Like the permanent magnet (5), the skin penetration needle (6) also vibrates,
This vibration prevents blood from coagulating and also causes an analgesic effect.

Ｏ）を介して血溜部（９）に防圧がかけられる。血溜部
（９）に溜まった血液は、この防圧により導管（１０）
、採血管（１１）を介して真空採血装置（ｂ）に送り出
される。When the blood exuding into the blood pool (9) reaches a predetermined type, the vacuum blood sampling device (b) is driven, and the blood sampling tube (11) and the conduit (l) are activated.
Pressure protection is applied to the blood pool (9) via O). The blood accumulated in the blood pool (9) is transferred to the conduit (10) by this pressure protection.
, and is delivered to the vacuum blood collection device (b) via the blood collection tube (11).
採血が終了した後、第３図（３Ｃ）に示すように、電圧
を停止し、本体及び針収納部（７）を皮膚組織（Ｉ１）
から剥ぎ取る。After the blood collection is completed, as shown in Figure 3 (3C), the voltage is stopped and the main body and needle storage part (7) are inserted into the skin tissue (I1).
strip it off.
本発明に於ける皮膚貫入用針（６）は、口径が数十ミク
ロンと、蚊か持つ針の口径に近似するものが好ましいが
、数ミクロン−数百ミクロンの範囲で設定されればよい
。従って採血が終了した後、皮膚組織に残る傷跡は非常
に小さく、針を抜き出した後、血液は即凝固し、傷跡か
ら血液か流れ出すことはほとんどないものである。The skin-penetrating needle (6) in the present invention preferably has a diameter of several tens of microns, which is similar to the diameter of a needle carried by a mosquito, but it may be set in the range of several microns to several hundred microns. Therefore, after blood collection is completed, the scar remaining on the skin tissue is very small, the blood coagulates immediately after the needle is removed, and almost no blood flows out from the scar.
又、上述した如く、本体（１）と針収納部（７）とは着
脱自在であることから、−個人ごとに針収納部（７）を
交換すれば、保健衛生上極めて好ましい態様にもなる。Furthermore, as mentioned above, since the main body (1) and the needle storage part (7) are removable, it is possible to replace the needle storage part (7) for each individual, which is an extremely desirable aspect from a health and hygiene perspective. .
本発明に於ける永久磁石（４）及び（５）は、同極又は
異極何れであってもよい。即ちこれら永久磁石は、移動
可能に設置されている永久磁石（５）に対し、反発力及
び牽引力を与えて、不使用時に於ける無用な針の移動を
１１１１止するものである。The permanent magnets (4) and (5) in the present invention may have the same polarity or different polarity. That is, these permanent magnets apply repulsive force and traction force to the movably installed permanent magnet (5), thereby stopping unnecessary movement of the needle when not in use.
又、本実施例に於いては本体及び針収納部を透明な材質
で成形することにより、血液の滲出ｍを目視によって測
定していたが、電気的センサー等を血溜部（９）に設置
することにより、電気的に測定してもよい。In addition, in this example, the main body and the needle storage part were molded with a transparent material, and the blood exudation m was measured visually, but an electric sensor or the like was installed in the blood pool part (9). It may be measured electrically by doing so.
以上本発明は、任愈の血液量を無傷で且つ適確に採血す
る口上が可能であり、人手を必要とＵ・ず、自動的な採
血ができる等の効果を有するものである。As described above, the present invention has the advantage that it is possible to collect a desired amount of blood accurately and without damage by mouth, and that blood can be collected automatically without requiring manual intervention.
