Technical Field [0001] The present invention relates to a solid contact medium for ultrasonic inspection and a manufacturing method thereof,

The present invention relates to a solid contact medium for ultrasonic inspection and a method of manufacturing the same, and more particularly, to a method of manufacturing a solid contact medium for ultrasonic inspection, which is used for improving the permeability during ultrasonic inspection, And it is possible to increase the satisfaction of the patient by reducing the application time due to the flowing down. Since the conventional ultrasonic gel is solidified and compacted, it is easy to hold and it is not necessary to store in a warm place, the preparation process before and after the examination is simplified, And to a method of manufacturing the same.

Ultrasonography is the trend of increasing inspection inspection and target area every year due to the application of health insurance. Such an ultrasonic inspection uses a contact medium as a material for improving the inspection efficiency by reducing the difference between the surface of the probe of the ultrasonic inspection apparatus and the impedance of the soft tissues and improving the permeability of the ultrasonic waves.

At this time, the contact medium should be a single medium and have an absorption coefficient similar to that of water, so that ultrasonic wave reflection should be avoided so that it can be used for inspection. Conventionally, oily ultrasound gel has been used as such a contact medium, but recently it has been replaced with aqueous ultrasound gel due to various inconveniences of oilseed.

However, the conventional liquid ultrasound gel is not only uncomfortable due to the cold during coating of the human body, but also is inconvenient to remove, and is removed due to friction and evaporation during the test. Therefore, And due to the characteristics of the liquid, the contact medium flows down during the inspection, so that the paper towel is overused and the cost increase and environmental problems may occur.

In addition, since the conventional ultrasonic gel is in a liquid state, it is inconvenient and needs to be stored in a warm room, and since measures are required to prevent the gel of the patient from getting wet during ultrasonic examination, preparation process before and after the examination is complicated .

Hereinafter, preferred embodiments of the present invention will be described. However, the embodiments of the present invention can be modified into various other forms, and the scope of the present invention is not limited to the following embodiments.

In addition, to include an element throughout the specification does not exclude other elements unless specifically stated otherwise, but may include other elements.

Solid contact medium for ultrasonic inspection

The solid contact medium for ultrasonic inspection of the present invention includes a liquid contact medium for ultrasonic inspection and wax. Hereinafter, for convenience of explanation, the liquid contact medium is defined as an ultrasonic gel and the solid contact medium is defined as an ultrasonic wave balm.

The ultrasonic gel includes water and a polymer, and may further include a wetting agent, a colorant, and an antiseptic agent. In the present embodiment, the ultrasound gel may be a super sonic gel of Sungheun Co., for example.

The wax serves to solidify the liquid contact medium. For example, various types such as beeswax (beeswax) or candelilla wax may be used, but in this embodiment, candelilla wax can be preferably used.

The beeswax is relatively invisible to the naked eye but has a relatively soft texture compared to candelilla wax and has a better shape retention than the candelilla wax when hardness tested.

The candelilla wax is a wax component extracted from candelilla which is a water-insoluble and belonging to the genus Liliaceae, and is a human-safe substance having a first degree of danger. Such candelilla waxes can be used as vegetable thickeners, emollients, binders, astringents, film formers, moisturizers, moisture barrier agents, emulsion stabilizers and thickeners.

In addition, the candelilla wax has a moisturizing effect and a conditioning effect for preventing moisture evaporation by supplying oil to the skin.

Therefore, the candelilla wax is not softer than the wax, can be solidified in a small amount, and is harmless to the human body. Therefore, it is more stable than the beeswax described above in applying to an ultrasonic inspection material which is in direct contact with the human body.

At this time, a preferable mixing ratio of the ultrasonic gel and the wax may be the ultrasonic gels 7 to 13 with respect to the wax 1. When the ultrasonic gel is mixed with the wax 1 at a ratio of less than 7, the ultrasonic gel may scatter due to excessive curing. When the ultrasonic gel is mixed with the wax 1 at a ratio exceeding 13, the fluidity becomes too large, There is a problem that ultrasonic waves are not properly formed.

In addition, the ultrasound chest may further include a moisturizing agent for enhancing a patient's satisfaction by providing comfort during examination, and for enhancing a moisturizing effect and a perfume. At this time, the perfume may be preferably aroma oil, and the humectant may be vaseline.

The fragrance may be included in an amount of 2 to 10 parts by weight based on 1 part by weight of the wax, and the humectant may be included in an amount of 0.2 to 1.0 part by weight based on 1 part by weight of the wax.

If the amount of the perfume is less than 2 parts by weight with respect to 1 part by weight of the wax, the fragrance may be mixed with the wax fragrance and the fragrance of the perfume may not be effective. If the amount is more than 10 parts by weight, It may become difficult to use it for ultrasonic inspection.

If the amount of the moisturizing agent is less than 0.2 part by weight based on 1 part by weight of the wax, the moisturizing effect may not be exhibited. If the amount is more than 1.0 part by weight, the hardness of the finished solidified contact medium may be excessively increased, It may cause problems that the medium is not suitable for ultrasonic inspection.

Since the solid contact medium for ultrasonic inspection according to the present invention is solid, it can be manufactured in various shapes such as circular (or coin), square, curved, and rod shape as required, So that it is possible to make the coating easier during the ultrasonic examination.

Particularly, since the solid contact medium for ultrasonic inspection in this embodiment uses candelilla wax having excellent effect of holding a shape when solidified, the shape can be maintained well when it is made into a rod shape, Forming contact medium is produced, it is suitable to be accommodated in a stick-shaped container to be described later.

Method for manufacturing solidified contact media for ultrasonic inspection

A method for producing a solidified contact medium for ultrasonic inspection having the above structure will be described. First, a mixture is prepared by mixing the liquid contact medium for ultrasonic inspection and the wax at a ratio of 7 to 13: 1.

Next, the mixture is heated in a heating bath tool at 75 to 85 DEG C, and then cooled at a low temperature at a low temperature to be solidified, thereby preparing a liquid contact medium for ultrasonic inspection.

At this time, the solidified solid forming contact medium 20 may be manufactured into a rod shape and then inserted into a stick-shaped container 10 having an open top as shown in FIG. The stick-shaped container 10 is hand-held by hand such that the inspecting person exposes a part of the solidified contact medium 20 in the form of a glue stick, and the solidified contact medium 20 is easily rubbed Can be applied. In this case, it is convenient to carry and store the solidified contact medium 20 and to prevent the solidified contact medium 20 from being buried in other areas than the region to be inspected during the ultrasonic inspection.

Experimental Example

Hereinafter, characteristics of the solidified contact medium for ultrasonic inspection manufactured by the above method will be described. As the solidified contact medium for the following experiment, the supersonic gel and the candelilla wax of the stigma were used as an ultrasonic gel, and they were liquefied by boiling at 80 DEG C using a heating bath tool, and then liquefied super sonic gel and candelilla wax were mixed And allowed to cool at room temperature for 60 minutes to solidify.

1. Mixing ratio of ultrasonic gel and wax

In order to determine the desirable mixing ratio of the ultrasonic gel and the wax, the mixing ratio between the ultrasonic gel and the wax is gradually increased from 5: 1 to 15: 1, and the solidifying operation is performed.

# Ultrasonic Gel (g) Wax (g) Mixing ratio (ultrasonic gel: wax) Scattering Solidification One 50 10 5: 1 Yes Ok 2 60 10 6: 1 Yes Ok 3 70 10 7: 1 No Ok 4 80 10 8: 1 No Ok 5 90 10 9: 1 No Ok 6 100 10 10: 1 No Ok 7 110 10 11: 1 No Ok 8 120 10 12: 1 No Ok 9 130 10 13: 1 No Ok 10 140 10 14: 1 No NG 11 150 10 15: 1 No NG

As shown in Table 1, in the samples 1 and 2 in which the mixing ratio of the ultrasonic gel and the wax was in the range of 5: 1 to 6: 1, scattering was observed due to excessive curing of the ultrasonic night, and the mixing ratio of the ultrasonic gel and wax was 14: In samples 10 and 11 having a ratio of 1 or more, the fluidity is too large to show solidification limit, and ultrasonic night is not formed properly. Thus, the ultrasound gel and wax showed the most ideal form in which the solidification was completely performed without exhibiting the scattering characteristics in Samples 3 to 9 having the mixing ratio of 7 to 13: 1. At this time, the intensity of the ultrasonic wave was suitable for the ultrasonic examination 25-30 (measured using a GS-200N model hardness tester manufactured by TECLOCK, Japan).

2. Transmission of Ultrasonic Night

Hereinafter, the transmittance of the ultrasonic wave according to the present invention is compared with that of the conventional ultrasonic gel. In the following experiment, the ultrasound night is preceded by the sample 6 of Experiment 1. For this experiment, an ultrasound gel and an ultrasound chest are first applied to the ultrasound multi-purpose phantom, respectively, and the image parameters of the ultrasound diagnostic apparatus are fixed and imaged to acquire an image as shown in FIG.

In this case, when each parameter is fixed to parameters such as gain, time gain compensation, dynamic range, and focus of the ultrasonic diagnostic apparatus and the contact medium is not used for the multi-purpose ultrasonic phantom (hereinafter referred to as Comparative Example 1) , A case of using an ultrasonic gel (hereinafter referred to as Comparative Example 2), and a case of using a Candellila wax (hereinafter referred to as an embodiment).

1 (a) is an image of Comparative Example 1, (b) is an image of Comparative Example 2, and (c) is an image of the embodiment. Here, the phantom is a multipurpose phantom for managing ultrasonic quality of Samsung Polymer. 1400 HTS, and the ultrasonic diagnostic apparatus uses a 3.5 MHz covex probe of GE LOGIQ P5.

Each image obtained in this way is used to evaluate the brightness and resolution after deriving the results using the image J program. At this time, the luminance value is measured by using the SPSS V.18 program after measuring the maximum value, the minimum value and the average value.

As a result, it was found that the average luminance value of Comparative Example 1 was 50.91, the average luminance values of Comparative Example 2 and Example were 71.06 and 70.71, respectively, and that the gray value was improved by 20 or more as compared with Comparative Example 1 . At this time, the standard deviation was 11.96 in the comparative example 1, 16.99 in the comparative example 2, and 16.98 in the example.

Table 2 shows the results of the gray-level statistical value by using the SPSS V.18 program for the comparison of mean values. As shown in Table 2, the significance probability of using ultrasound gel and ultrasound chest was statistically less than 0.05 when compared to the case of using no contact medium, and the probability of significance of ultrasound chest and ultrasound gel was statistically significant I did.

This indicates that the ultrasonic wave of the present invention has a similar transmittance to that of a liquid ultrasonic gel, and thus the ultrasonic wave can be used as a contact medium even though the ultrasonic wave is solid.

3. Comparison of convenience and discomfort when using ultrasound gel and ultrasound night

The results of the statistical analysis of the results are shown in Table 3. The results are shown in Table 3. The results were as follows: Respectively. The subjects were 28 males and 22 females. The age of the subjects was 3 in their 20s, 42 in their 30s, and 5 in their 40s.

Item Comparative Example 2 Example Satisfaction Average Value 2.5000 3.6600 Satisfaction standard deviation 1.21638 1.23899 Satisfaction t -4.72400 -4.72400 Satisfaction p-value 0.000 0.000 Convenience Average Value 2.6200 3.6600 Convenience standard deviation 1.35360 1.33417 Convenience t -3.86928 -3.86928 Convenience p-value 0.000 0.000

Referring to Table 3, the average value of satisfaction in Comparative Example 2 was 2.5000 and the average value of satisfaction in Example was 3.6600. In the case of using the ultrasonic night as the contact medium according to the present invention, the satisfaction rate was higher, Since both are less than 0.05, we can see that all the results between the two items are statistically significant. The results are evaluated as being due to the discomfort caused by the ultrasonic gel of Comparative Example 2 because it provides a colder touch than the ultrasonic wave of the Examples.

In addition, the results of the convenience evaluation of the comparative example 2 and the comparative example 2 were 2.6200, and the convenience of the embodiment was 3.6600, indicating that the convenience of the embodiment was higher. In this case, the p- Since both are less than 0.05, we can see that all the results between the two items are statistically significant. The results are evaluated to be due to the fact that the application time of ultrasound examination in the case of ultrasound examination is reduced by the evaporation, and the amount of application is relatively small and the removal is easy. If the application amount of the contact medium is reduced, the use amount of the paper towel can be reduced, thereby contributing to cost reduction and environmental improvement.

Then, an ultrasonic inspection using the comparative example 2 and the example was performed on the same object, and the possibility of supersonic wave night substitution of the embodiment was surveyed. As a result, it can be seen that the substitution result as the contact medium for ultrasonic inspection of the embodiment has an utility value because the average value is 3.9000 and the standard deviation is 1.11100. At this time, t is 24.81800 and the p-value is 0.000, and the result is statistically significant because the p-value is less than 0.05.

In addition, we examined the possibility of ultrasonic night substitution according to sex and age. As a result, X ² was 5.6910 and p-value was 0.22300, and X ² was 12.1150 and 0.14600, respectively. That is, the p-value is 0.05 or more in the cross-sectional analysis of the sex and the item, and it is evaluated that there is no difference in the response according to sex and age range. Thus, in the conventional ultrasonic gel regardless of sex and age, It is possible to confirm that the possibility of replacing ultrasonic rice is generally positive.

Therefore, based on the above-described experimental results, the ultrasonic wave according to the present invention has an excellent transparency, can prevent discomfort when applied to the surface of a conventional ultrasonic gel, It is possible to replace the conventional ultrasonic gel in various aspects.

The present invention is not limited by the above-described embodiment and the accompanying drawings, but is intended to be limited by the appended claims. It will be apparent to those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. something to do.
