Abstract: An ultrasonic toothbrush for use in personal dental hygiene care includes an exchangeable ultrasonic implement which may be rigidly and removably mounted to ultrasonic power means and readily removed therefrom with a relatively small separating force. Provision is made for coupling the toothbrush to the power means and is arranged to transfer the ultrasonic energy from the power means to the ultrasonic implement with the power means remaining substantially free from absorbing ultrasonic energy as the vibratory energy is transmitted therethrough.

Abstract: An ultrasonic toothbrush for use in personal dental hygiene care includes an exchangeable toothbrush member which is removably attached to an ultrasonic power member and may be readily removed therefrom with less than one revolution and inserted on to the ultrasonic power member in a like manner. Provision is made for locking the toothbrush to the power member and is arranged to transfer the ultrasonic energy from the power member to the toothbrush with minimum energy loss.

Abstract: An auxiliary enclosed fluid supply unit or system that is adapted to be used in conjunction with commercially available professional dental and medical equipment to permit the user to select a variety of fluids to be administered to the patient during dental and other procedures and maintain desired levels of sterility in the operative cite of the patient.

Abstract: The invention relates to the field of hygienic care of the human skin and for performing certain dermatological procedures as removing blackheads and opening pimples with an ultrasonic applicator. The applicator or tool, which is used in conjunction with a selected fluid, has a contoured configuration or surface that is placed in energy transmission relationship to the skin and ultrasonically vibrated for performing the particular procedure desired.

Abstract: The treating of hair on the human head is obtained by providing a cylindrical shaped support member capable of transmitting ultrasonic vibrations in a radial mode and placing hair around the support member to receive vibrations transmitted thereto. A cover is disposed substantially around the support member as an ultrasonic transducer adapted to produce radially directed vibrations is positioned within the support member. A treatment fluid is simultaneously supplied to the hairs supported on the support member, and by energizing the transducer ultrasonic vibrations are radially transmitted through the support member for treatment of the hair with the cover substantially retaining the fluid around the support member.
