초음파 전파 매개물은 초음파의 손실 없는 투과력을 위한 1차적인 목적 이외에 피부위에서 탐촉소자의 부드러운 이동을 위한 부가적인 목적이 있다. 본 연구는 제형이 다른 진단초음파 전파매개물이 갖는 피부 윤활성, 피부 보습성, 건조속도 등의 초음파 매개물의 특징을 측정하고 비교하였다. 마찰계수는 점도가 높을수록 높았으며 제제의 건조속도는 고분자 수화젤이 가장 높았다. 오일 함유량이 많을수록 수분증발이 나타나지 않았다. 피부수분함량에서는 저점도 에멀전이 높은 수분함량을 나타냈으며 수분함량 감소 정도가 가장 완만히 나타났다. 오일성분을 적절히 사용한 에멀전 형태의 초음파 전파매개물은 피부 보습효과, 피부 유연작용의 피부 건강측면과 피부-탐촉소자간의 피부 윤활성면에서 효과적인 제형임을 알 수 있었다.

When diagnostic ultrasounds are used, an ultrasonic transmission media is used to effectively transmit the ultrasonic energy. Types of ingredients of polymer hydro gel, emulsion, and oil gel were compared with commercialized products by measuring characteristics of ultrasonic transmission media such as skin lubricity, skin moisturizing, and dryness speed which were contained in each different media. The mean friction coefficient measured to investigate skin lubricity showed high in the agent containing a large amount of oil, whereas the mean friction coefficient of the low viscosity emulsion did not show a significant difference with that of the polymer hydro gel. The moisture evaporation measured to investigate the dryness speed of the agent showed highest in polymer hydro gel. This showed that the larger amount of oil it had, the less moisture evaporation occurred. For skin moisture measured to investigate moisturizing characteristics of skin, low viscosity emulsion showed high in moisture content, whereas it showed slowest reduction in moisture content. As a type of emulsion appropriately containing water and oil is superior in skin moisturizing and skin tenderness, it is expected to serve as a dosage form of new ultrasonic transmission media.

In this study, by combining a unique purpose and additional aspects of ultrasonic transmission media, a development potential on a new ultrasonic transmission media was sought. The rheological characteristics and the manufacturing cost for each manufactured formulation were compared and analysed with ready-made. An ultrasonic transmission media is to have different functional characteristics according to the following formulation, it was the best in rheological value, low viscosity emulsion with the oil gel. Polymer hydro gel is can be manufactured at low cost compared to other formulations. Emulsion which shows a sharp viscosity difference according to the components of oil and water had a big difference in manufacturing cost. This study can be utilized as the fundamental data on the ultrasound transmission media equipped with expertise in various areas of ultrasound.
