Description

This disclosure relates to a cartridge for an ultrasonic irradiation device and a method thereof. Ultrasound refers to waves with frequencies of 20 kHz or higher. Because it has the property of penetrating water, it is widely used in the medical field, such as in ultrasound diagnostic equipment and ultrasound irradiation devices. In the medical field, the most representative application of ultrasound is ultrasound imaging devices that utilize the transmission and reflection properties of ultrasound. For example, there are devices that visualize the time and intensity of ultrasound as it penetrates the human body, passing through various organs, to obtain cross-sectional images of the body. Furthermore, there are devices that utilize the heat generated by high-intensity focused ultrasound (HIFU) to burn and remove specific subcutaneous tissue, such as tumors within the skin, or to induce degeneration and regeneration of skin tissue, thereby producing cosmetic or dermatological effects such as wrinkle reduction. Conventional ultrasonic irradiation devices irradiate the transducer while it is immersed in distilled water to prevent it from being struck. However, conventional ultrasonic irradiation devices have limitations in efficiently irradiating ultrasound under fluctuating conditions such as the evaporation rate, remaining amount, and tilt of distilled water. This limits their ability to extend the lifespan of the transducer and prevent accidents caused by ultrasonic irradiation.

Reference numerals identical throughout this disclosure indicate the same component. This disclosure does not describe all elements of each embodiment, and general content in the art to which this disclosure pertains, or content that is redundant in the embodiments, is omitted. The terms “parts, modules, components, and blocks” as used in this specification may be embodied in software or hardware, and in embodiments, multiple “parts, modules, components, and blocks” may be embodied as a single component, or a single “part, module, component, and block” may include multiple components. In the entire specification, when one part is described as being "connected" to another part, this includes not only direct connections but also indirect connections, and indirect connections include connections via wireless communication networks. Furthermore, when a part is described as "containing" a certain component, unless otherwise specified, this means that it can include other components rather than excluding them. Throughout the specification, when a component is described as being "on top of" another component, this includes not only cases where the component is in contact with another component, but also cases where another component exists between the two components.

Unless the context explicitly states a specific order, the stages may be performed in a different order than that specified. The operating principle and embodiments of this disclosure will be described below with reference to the attached drawings. First, High-Intensity Focused Ultrasound (HIFU) technology uses the heat generated when high-intensity ultrasound is focused on a single point within the skin to burn specific subcutaneous tissues, such as tumors. This principle is similar to using a magnifying glass to focus sunlight and start a fire. Because ultrasound easily penetrates body tissue, HIFU irradiation is performed in a completely non-invasive manner, without the
