Definitions
- the present invention relates to a transmission medium for ultrasonic sound diagnosis, and more particularly to a transmission medium for ultrasonic sound diagnosis characterized by containing a hydrocarbon, ether or ester having a specific viscosity.
- conventional polyglycerin and polypropylene glycol have insufficient adhesion to solids, which is called thixotropic property, and it takes two to three minutes to fix and stabilize the film quality. From the viewpoint of efficiency of inspection, etc., a transmission medium that can be measured immediately after the application of the transmission medium, that is, a transmission medium having good solid adhesion has been required.
- transverse waves can be transmitted in non-contact measurement where the test object or probe is immersed in the transmission medium. There is a problem that it cannot be performed, and a transmission medium that can transmit shear wave ultrasonic waves even in a non-contact state has been desired. Disclosure of the invention
- the present invention does not cause moisture generation of a subject and does not have hygroscopicity that deteriorates propagation characteristics during use, and solid-state adhesion is imparted in a short time. It is intended to provide a transmission medium for sound diagnosis.
- the present inventors have found that a transmission medium for ultrasonic sound diagnosis containing an ester compound has low hygroscopicity and excellent transmission properties, and has completed the present invention.
- FIG. 1 is a schematic diagram illustrating an ultrasonic transmission characteristic evaluation method according to the present invention.
- the ultrasonic wave in the present invention refers to an elastic wave having a frequency exceeding an audio frequency range, and includes a horizontal shear wave (SH wave), a vertical shear wave (SV wave), and a longitudinal wave (L wave). It is.
- SH wave horizontal shear wave
- SV wave vertical shear wave
- L wave longitudinal wave
- the transmission medium in the present invention needs to have a viscosity of 100 mPas or more at the operating temperature, that is, the measurement temperature.
- the range of 100 to 300 m0 Pas is preferable, and the range of 100 to 150 mPas is more preferable. I like it. If the viscosity is less than 1000 mPa ⁇ s, transverse ultrasonic waves cannot be transmitted. On the other hand, if the viscosity exceeds 3 0 0 OOO mPas, the viscosity may be too high and the handling property may be poor, making it difficult to use as a transmission medium.
- the hydrocarbon compound in the present invention is not particularly limited as long as it satisfies the viscosity condition, but is preferably a rigid compound having a ring structure or a quaternary carbon.
- hydrogenated hydride, ⁇ -methylstyrene oligomer, ⁇ -methylstyrene oligomer, and the like is preferable.
- the ether or ester compound in the present invention satisfies the viscosity condition and has a ring structure. This is because in the case of a flexible structure without a ring structure, the transmissivity of the shear wave is low.
- ring structure examples include a cyclohexane ring and a cyclohexane ring.
- saturated rings such as bicyclo [3,3,0] octane ring
- aromatic rings such as benzene ring, naphthalene ring, anthracene ring, fluorene ring, indane ring and acenaphthene ring.
- a paraffin-based hydrocarbon or an ester compound may be mixed as the mixing base material.
- the mixing ratio can be arbitrarily set within a range that satisfies the above viscosity condition, but is usually 1 to 95 mass. / 0 , preferably in the range of 5 to 80% by mass.
- FIG. 1 is a schematic diagram showing a method for evaluating ultrasonic transmission characteristics according to the present invention.
- the receiving sensitivity (V) was measured using SH and L waves at 5 MHz.
- a sound diagnostic device (USH-B manufactured by Toshiba Tungaloy Co., Ltd.) was used for ultrasound transmission / reception and waveform analysis. - ⁇ Example 1>
- ⁇ -alumina N6-12N manufactured by Nikki Chemical Co., Ltd.
- the reaction temperature was 285 ° C and the weight hourly space velocity (WH SV) was 1.1 hr-1.
- the dehydration reaction was carried out at 1 , and the 2-methylene3, -methylbisic port [2,2,1] heptane and 2,2 3
- the dehydration reaction product of 2-hydroxymethyl-3-methylbicyclo [2,2,1] heptane containing 1-dimethylbis [2,2,1] heptene 2-ene was obtained.
- the oligomerization reaction was performed at 20 ° C for 6 hours.
- the reaction mixture was washed with a dilute aqueous sodium hydroxide solution and saturated saline, and then charged to a 1 liter autoclave with a nickel / casseolite catalyst for hydrogenation.
- Table 1 shows the results of evaluating a mixture of Fluid 2 (79% by weight) and Fluid 1 (21% by weight) as an ultrasonic transmission medium.
- the transmission medium according to the present invention has high reception sensitivity for transverse ultrasonic waves, and reception sensitivity for longitudinal ultrasonic waves is comparable to conventional glycerin-based transmission media.
- Table 1 shows the results of evaluation of a commercially available polyglycerin-based transmission medium as an ultrasonic transmission medium immediately after coating and 5 minutes later.
- Table 1 shows the results of evaluating the same transmission medium as in Example 1 as an ultrasonic transmission medium 5 minutes after application.
- the transfer medium of the present invention did not show a decrease in the consultation sensitivity that occurred over time. No.
- the ultrasonic transmission medium of the present invention does not cause the generation of ⁇ in the subject, does not cause the deterioration of the propagation characteristics during use, has good solid adhesion, and has good transmission even in a non-contact state such as immersion. It is an excellent ultrasonic transmission medium.
- the transmission medium for ultrasonic sound diagnosis according to the present invention is a force that can be used for both shear wave ultrasonic wave and longitudinal wave ultrasonic wave. obtain.
