る。Here, if the presser lid body 8, which serves as an open lid, is laid down in advance on one side of the base plate 3 to form a closed lid shape, the lower end 10a of the gate-shaped support frame 10 built into the presser lid body 8 will fit into the stepped portion. At this time, the elevating presser piece 13, which is slidably fitted into the support frame 10, comes into contact with the base plate surface 3a at the outside position of the support frame 10, and is stopped by the elastic force of the spring 15 provided on the support shaft 16. In the extended state, the V-shaped receiver fits into the groove 2 side, and the V-shaped receiver holds down the specimen tail Aa portion guided by the groove 2.

ため、該昇降押え駒体１３下面は確実に検体尾Ａａへ密
着状となる。In this case, the diameter of the specimen tail Aa will of course vary depending on the size of A itself. Since the elevating presser foot 13 is constantly pushed downward by its own weight and the elastic force of the spring 15 attached to the support shaft 16, the lower surface of the elevator presser foot 13 is securely attached to the specimen tail Aa. It becomes a close contact with the body.
勿論、この検体尾Ａａが大径のときは、昇降押え駒体１
３はスプリング１５に抗して上方へ押上がるものとなる
。Of course, when the specimen tail Aa has a large diameter, the elevating presser foot 1
3 is pushed upward against the spring 15.
即ち、検体尾Ａａの上下位置には光源２０とセンサーと
なる受光器４が密接状態として配されたものとなる。That is, the light source 20 and the light receiver 4 serving as a sensor are arranged in close contact with each other above and below the sample tail Aa.

に配した受光器４に受光されるものとなる。In this state, if the switch 25 of the measuring device body 24 is turned on and the light source 20 of the detector 1' is turned on, the light source consisting of four sides will pass through the sample tail Aa, and the light beam will be directed to the opposite side (downward).
The light is received by the light receiver 4 placed at.

再び血流が開始する。In this case, the pressure conversion pump mechanism 29 is actually driven,
The bladder portion of the cuff 23 connected to the pump mechanism 29 is inflated and the sample tail Aa inserted therein is compressed to temporarily stop the blood flow, and the compressed state due to the decompression of the cuff 23 is released. Blood flow starts again.

を確実にとらえ得る。32 is a pressure meter, and 33 is a panel board. As mentioned above, the detector of the present invention has a light receiving side that guides the sample tail.■ The receiver has an elevating presser at the top of the groove that serves as the light source side that moves up and down according to the diameter (thickness) of the sample tail. By having a structure with a bridge body, it is possible to transmit light to the specimen tail in close contact with it at all times, and (2) it is possible to reliably detect changes in blood flow with the light receiver placed at the bottom of the groove.
しかも、この場合昇降押え駒体は、Ｖ状受は溝部に閉蓋
とする押え蓋体に内蔵形成してなるため、検体尾に対す

が簡単である。In addition, in this case, the lifting presser piece is formed with a V-shaped receiver built into the presser cover which closes in the groove, so the presser against the sample tail can be simply closed by closing the cover, making the handling process easy. It is.

ては正確な血流信号を得る。In addition, this elevating presser piece itself is guided by its own weight by an engagement strip that is groove-fitted to a fixed gate-shaped support frame that contacts the base plate surface, and there is a gap between the elevating presser piece and the support frame. Since a spring is interposed between the upper and lower sides, it is possible to move up and down reliably in the vertical direction, which also improves the adhesion to the specimen tail.Moreover, the light source for this receiver is the chevron-shaped presser foot of the lifting presser piece. Since the structure is divided into four directions (front, rear, left and right), it does not apply thermal stimulation to the specimen tail, and can reliably handle large and small diameters, resulting in accurate blood flow. Obtain a flow signal.
更に本考案は構成が簡略化してなるため、製作が容易で
、且つ長期使用に耐える等の実用的効果を奏する。Furthermore, since the present invention has a simplified configuration, it is easy to manufacture and has practical effects such as being durable for long-term use.
