A personal care device, such as an electric toothbrush, has a handle having a longitudinal axis and a treatment head connected to a carrier. The carrier extends within the handle and is mounted at the handle for pivoting motion around a pivot axis against a restoring spring force. A drive unit, such as a linear actuator, is mounted on the carrier, and at least one electrical connector is arranged between the handle and the carrier to convey electrical energy from an energy source fixedly mounted with respect to the handle to the drive unit. The electrical connector can be realized as an elastic metal sheet element having a spring constant for providing at least a part of the restoring spring force.

A method of relieving a hyperirritable area on or surrounding a mandible. The method may include steps of selecting a first head component from a set of head components of a myofascial release apparatus (MRA); connecting the first head component with a handle of the MRA; locating the hyperirritable area on or surrounding the mandible of a patient experiencing muscle tension; contacting the hyperirritable area, via a contact member of the first head component, on or surrounding the mandible of the patient; actuating a motor of the MRA, via an electrical control assembly of the MRA, from an OFF state to an ON state for vibrating the first head component at at least one predetermined frequency; and relieving the hyperirritable area on or surrounding the mandible. Optional steps may be included when using other head components provided in the set of head components.

A handpiece assembly for a medical device has a handpiece having a handpiece distal portion for receiving an insert assembly including a radiofrequency identifier, an insert antenna and an insert. A handpiece antenna is arranged in the handpiece distal portion. Radiofrequency signal supply means provide radiofrequency signals to the handpiece antenna that communicates with the insert antenna when the insert assembly is inserted in an insertion region in the handpiece distal portion. The handpiece antenna is a loop antenna or segmented ring antenna having at least two segments. A first end of a first segment is connected to a first terminal of the radiofrequency signal supply means, a second end of a last segment is connected to a second terminal of the radiofrequency signal supply means, forming a coil radiating structure generating an electromagnetic field. Each segment has a radiant metal element, with respective inductance, electrically connected to a respective capacitive element. A medical device including a control element, an insert assembly, and the handpiece assembly is also provided.

The charging stand for a care apparatus according to the present disclosure includes a fifth terminal connected to a first terminal, a sixth terminal aligned with the fifth terminal and electrically connected to a second terminal, a first cover having a cylindrical shape that stores the first terminal, a second cover having a cylindrical shape that stores the second terminal, a fifth cover having a cylindrical shape that stores the fifth terminal, and a sixth cover having a cylindrical shape that stores the sixth terminal. A shape of an input connecting portion formed by the fifth cover and the sixth cover is different from a shape of an output connecting portion formed by the first cover and the second cover.
