Method for increasing cell viability by using drug delivery system and ultrasound irradiation, and ultrasound irradiation apparatus using same

An ultrasound irradiating device for increasing a viability of one or more cells by irradiating the cells with ultrasound, comprising:

• an ultrasound transducer;
• and
• a controlling part, on condition that a drug and an epidermal drug carrier are applied on epidermis of a subject and that ultrasound parameters have been preset within respective ranges, for positioning the ultrasonic transducer within a threshold range from the epidermis of the subject and then allowing the ultrasonic transducer to irradiate the epidermis with the ultrasound;
• and
• wherein the epidermal drug carrier causes cavitation to create at least one cavity around the epidermis in response to irradiating the epidermis with the ultrasound, and
• wherein the ultrasound parameters include a pressure of the ultrasound and a duty percentage of the ultrasound, wherein the pressure of the ultrasound ranges from 0.5 MPa to 1 MPa, and wherein the duty percentage of the ultrasound ranges from 1% to 5%.
