For the purpose of stably performing blood flow measurements etc. for a long time by inserting and fixing the ultrasound probe into the cavity of the holder, the axis perpendicular to the transducer surface of the ultrasound probe and the body surface are set at 30 to 75 degrees. A fixing holder is provided with a cavity that can be inserted at a predetermined angle within the range of 100° and fixed near the body surface.

尚、第２図従来の構成について簡単に説明する。For this reason, conventional methods have a through hole through which the ultrasound probe is inserted with its axis perpendicular to the transducer surface and the blood vessel axis at a predetermined angle within the range of 30 degrees to 75 degrees, as shown in Figure 2. Measurement was carried out by fixing the ultrasonic probe 13 using a water holder 11 for fixing the blood flow measurement ultrasonic probe. This through hole 1
4 is provided because the material of the fixing holder 11 used conventionally is Teflon or silicone rubber. This is because if there is an intervening interface, the acoustic impedance will be different from that of the human body, and ultrasonic waves will be reflected at the interface. When this reflection occurs, not only does the blood vessel being close to the ultrasound probe cause multiple reflections that interfere with measurement, but the frequency of the ultrasound used to measure blood flow velocity and its profile is as high as 3 to 30 MHz. Therefore, the ultrasonic waves are severely attenuated, making it difficult to accurately measure blood flow velocity.
Therefore, measurements were taken by filling the bottom portion of the through hole 14 in contact with the body surface with a substance through which ultrasonic waves can easily pass, such as liquid ultrasonic gel. However, there was a problem in that this ultrasonic gel leaked out during measurement, making it difficult to perform stable measurements over a long period of time.The conventional configuration is briefly explained in Figure 2. .

The space between this ultrasound probe 13 and the body surface was filled with ultrasound gel 12. During use, this liquid ultrasonic gel 12
was often leaked.

り、作成が簡単かつ構造が簡単となる。In FIG. 1, the cavity 4 of the fixing holder 1 has an angle θ of 30 to 75 degrees with respect to the body surface of the ultrasound probe 3.
It is fixed at a certain angle within a degree range. The bottom part 2 of this cavity 4 is made of a material (gelled polyvinyl alcohol aqueous solution in the range of 15 to 30 weight percent) that has approximately the same acoustic impedance as the living body, so it cannot be inserted into this cavity 4. The ultrasonic probe 3 fixed in place can transmit and receive ultrasonic waves through the bottom portion 2 without causing any reflection on the body surface. Further, by integrally forming the bottom portion 2 of the cavity portion 4, it is easy to fabricate and the structure is simple.

It is pressed against the surface of the body to measure things such as blood flow velocity.

明する。Next, regarding the bottom 20 portion of the cavity 4 of the fixing holder 1, we will discuss the material that has an acoustic impedance approximately equal to the acoustic impedance of a living body, the hardness as a solid at that time, and the procedure for creating it using this material. The process of discovering the substance related to the present invention will be explained in detail one by one.
第１に、超音波探触子３を空洞部４内に挿入して固定し
、血流速な゛どを計測するときに当該超音波探触子３の
角度が変化しないだけの硬さが必要である。First, the ultrasonic probe 3 is hard enough that the angle of the ultrasonic probe 3 does not change when it is inserted into the cavity 4 and fixed to measure blood flow velocity, etc. is necessary.
第２に、人体の皮宥に直接に接触し、あるいは冠血管の

させないようにするためである。Third, it is necessary that the acoustic impedance be in the range of 1.4 XIO' to 1.7 XIO'g/m"/s. This is to prevent reflection of ultrasound from the human body.
第４に、減衰率が０．４ ｄＢ／ｃｎ／Ｍｌ（ｚ以下で

２回、超音波が通過することによる減衰を可及的に小さ
くするためである。以下考察する。Fourth, the attenuation rate must be 0.4 dB/cn/Ml (z or less. This is to minimize the attenuation caused by the ultrasonic wave passing through the acoustic coupler 2 twice, on the way out and on the way back. This is to make the size smaller.This will be discussed below.

料はなかなか見当たらなかった。For example, Teflon satisfies the first and second conditions but does not satisfy the third and fourth conditions, and silicone rubber satisfies the first and second conditions.
, there are materials that satisfy the second condition and the third or fourth condition, but there is no material that satisfies all the conditions, and it is difficult to find other materials that satisfy all the conditions. I couldn't find it.

足する。After examining a large number of materials, the present inventors have found a substance that satisfies all of these conditions among high water content gelled products. Examples of gelled products with high water content include agar gel and gelled products of konjac (konjac) and polyvinyl alcohol (hereinafter referred to as PVA) aqueous solutions.It is necessary to limit the composition of these products, but the third condition is the acoustic impedance. satisfy.

Only for the gelled product of aqueous solution A, we were able to find a composition range that allows reliable long-term measurement.

も大きな変形を起こさない硬さが得られた。The factors that contribute most to the physical properties of the gelled product of PVA aqueous solution are:
PVA is 111 degrees, and the higher the concentration, the harder it becomes.
Regarding the first condition related to the present invention, "angular displacement of the fixed ultrasonic probe 3," it was confirmed that the allowable range of 15 g of PVA is 15% by weight or more. P
An aqueous solution in which 15 g of VA is dissolved in 100 g of water is injected into the mold in which the fixing holder 1 in Fig. 1 is a space, and -30
By cooling the fixing holder 1 to °C, thawing it, and repeating the cooling/thawing process five times, it was possible to obtain a hardness that would not cause large deformation even when the fixing holder 1 was held between fingers.

The upper limit of 9 degrees is limited by acoustic impedance. That is, the acoustic impedance of the gelled PVA aqueous solution increases as the PVA15g content increases, and at 30% by weight it is 1.7xlO'Kg/wa"/s, which is within the allowable range. However, at 35% by weight, .9xlO

Regarding the speed of sound, PVA from the ultrasound probe 3 to the human body
Although the gelled aqueous solution has a structure in which the lengths are different, the influence can be ignored by correcting the angle of the ultrasound probe 3.

7.5 dB/cm at MHz (0.25 dB/MHz
), but since the length between the bottom 2 of the cavity 4 and the body surface is at most about 2II11 in the long part, the loss of ultrasonic waves in the round trip is about 3dB, which is within the allowable range and can be used. It is.

For example, the finger press part 6 and the finger scissor part 5 that constitute the fixing holder 1 may be made of materials with different hardnesses. In that case, the softer one may be prepared first, then the softer one may be heated to a temperature slightly lower than its melting point, the hard one may be melted and poured into this to be integrally molded.
