In recent years, ultrasound diagnostic equipment has become popular for examining the presence of abnormalities in organs within the human body, examining skin and skin tissues, and detecting fetal pulsations and blood flow. It came to be used for. When performing tests using this diagnostic device, water, vegetable oil, mineral oil, glycerin, liquid paraffin, or an amorphous gel is typically used to prevent ultrasound attenuation between the transducer and the human skin. or apply a self-adhesive film. When applying liquids such as water, oil, and liquid paraffin, use J as a contact medium.
Sumi only lasts for 1 to 2 hours at most, and in the case of oil or liquid paraquinol, it is difficult to cure the patient's skin after diagnosis.
I need to wipe it off. trench, as a contact medium 1['I
In cases where Kyobon is necessary, a plastic ice bag is filled with water and applied to the measurement site, which is called the water immersion method. To prevent this, it is necessary to use deaerated water, and if you use an ice bag, there is a risk of water spilling 2). Amorphous gel 1 (4 machines ζ affected, 1-Jljjke no 1 section (c) circulated more widely than water or oil)! , but it is only about 1 to 2 nn at most. What's more, it is superior to the probe; the thickness is 17iL from V, and the diagnosis (1> requires the thickness to be wiped off. In the case of self-adhesive film, it is necessary to wipe it off for diagnosis. Although it can be easily peeled off afterwards, the thickness is at most 1F or less.

In contrast, the J-role catalyst body of the ultra-sweat index probe of the present invention is a hydrogel with a water content of 80%. By inserting it between the hair and shoulders, it is possible to almost completely prevent the ultrasonic waves from being emitted. Even after diagnosis, you can remove it without washing it off. C1. Therefore, diagnosis can be made without causing any discomfort to the person to be diagnosed. In addition, there is no need to prepare degassed water when using an ice bag for JTj. Furthermore, the hydrogel according to the present invention has sufficient strength and can be used to move the probe from side to side when obtaining cross-sectional images using the echo method, for example. Diagnosis is performed, but the gel may collapse during this time.

However, the contact +9Lf medium of the present invention has 1. The gel strength is optically strong, the thickness can be easily adjusted by cutting the gel, and in some cases, it is possible to use two sheets in a stack. Even when making a diagnosis using an electronic focus type probe, it is possible to diagnose different parts of the skin by adjusting the thickness of the contact medium without changing the probe. This has an advantage.Especially, the price of one probe is high for devices that obtain one dynamic image of real-time display that are currently on the market. Although it is a large burden on the operator, the present invention allows contact with only one probe when using J, B/ζ.

Furthermore, since the contact medium according to the present invention has a gel strength that is optically strong, it may be fitted into the tip of the probe in some cases. It is also possible to use Such use facilitates transrectal diagnosis and provides clear images. For example, when performing surgery inside an organ, diagnosis of the inside of the organ can be easily and appropriately performed by directly applying a probe fitted with a contact medium according to the present invention to the surface of the organ after laparotomy. It has a number of points that allow for rapid surgery.

Short fibers or fibrous materials may be added, such as 61:1 in No. 674, or plasticizers, gelling agents, and antifoaming agents may be added. However, in order to achieve the object of the present invention, the hydrogel must be homogeneous to ultrasonic waves, and the inclusion of air bubbles must be prevented as much as possible. Furthermore, when adding plasticizers, gelling agents, other matrices, etc. other than polyvinyl alcohol, the dispersion of these in the sweat gel should be as uniform as possible, and these secret agents and water content should be It is necessary to choose one that does not cause a difference in gel density.

In addition, freezing treatment temperature and treatment +1. ! The time between r has a large influence on the strength and flexibility of the frozen gel obtained.
If the freezing temperature is too high, the gel will not be frozen sufficiently and the gel will become soft. The preferable cold σ+i treatment Jl gastric crystallinity is 1°C to -70°C1, especially -1 (1"C
- to -50°C is acceptable for this purpose. In addition, it is preferable that the moisture content of the frozen gel of the present invention is low from the viewpoint of gel strength, but on the other hand, it is desirable to prevent the attenuation of ultrasonic waves as much as possible, and to make the density of the gel closer to the density of the skin. It is preferable that the water content is as high as possible.In order to achieve the object of the present invention, it is desirable that the moisture content be at least 8 (7) ml.
