本発明は医療用に使用される血流状態を測定する血管装
着用プローブとこのプローブを操作する治具に関するも
のである。The present invention relates to a blood vessel attachment probe used for medical purposes to measure blood flow conditions, and a jig for operating this probe.
通信、医療等の分野で広く超音波が利用されている。特
に医療分野における応用の進歩は著しいものである。Ultrasound is widely used in fields such as communications and medicine. In particular, the progress of application in the medical field is remarkable.
この超音波利用の１部に血管内の血流状態を測定するも
のがある。この使用される状態は手術中に用いられるこ
とが多く、従って操作性が容易でしかも、測定値が正確
であることが必要である。One part of the use of ultrasound is to measure the state of blood flow in blood vessels. This state of use is often used during surgery, and therefore it is necessary that the operability is easy and the measured values are accurate.

音波を送信し血流によって反射する超音波で血流状態を
測定する。When measuring blood flow using this probe, the probe is attached by placing the notch A against the blood vessel and storing the blood vessel in the notch A against the elasticity of the blood vessel. After that, ultrasonic waves are transmitted and the blood flow state is measured using the ultrasonic waves reflected by the blood flow.
この際、血流及び血圧によって血管は、切欠き部Ａから
はみ出して、血管形状を変形させる。この変形によって
正確な血流状態の測定が不可能であった。At this time, the blood vessel protrudes from the notch A due to blood flow and blood pressure, deforming the blood vessel shape. This deformation made it impossible to accurately measure the state of blood flow.
上記したように、従来の血管装着用のプローブは、測定
が不正確であると云う問題があった。As described above, conventional probes for use in blood vessels have a problem in that measurements are inaccurate.
本発明はこのような点に鑑みて創作されたもので簡易な

ある。The relative positional relationship is such that the grasping part 4-3 is slid to the left side in the figure,
When the tip 4-4 passes over the projection 3-3 to the left, the flat projection 4-5 is positioned on the projection 3-4. Therefore, when the flat protrusion 4=5 is located on the protrusion 3-4, the tip 3-2 is open, and the tip 4-4 is also opened. When the grasping part 4-3 is moved to the right, the protrusion 3-4
The flat protrusion 4-5 is removed, the tip 3-2 is closed, and the tip 4-4 is closed by the protrusion 3-3. Note that when the tip 4-4 is on the left side of the projection 3-3 and the tip 3-2 is in an open state, the concave surface of the probe described above is in a circular state.
従って、プローブの血管装着は把握部４−３を左右に動
かすのみにて行えることとなる。Therefore, the probe can be attached to the blood vessel by simply moving the grasping section 4-3 from side to side.
