Abstract: A replacement head for detachable coupling to an oral care implement body. The replacement head may include a head having at least one treatment element and a tubular sleeve extending from the head and defining a cavity having an axis that receives a stem of the oral care implement body. The tubular sleeve may have a proximal edge that defines an opening into the cavity. A slot in the tubular sleeve is configured to mate with a boss of the stem of the oral care implement body. The slot may include an entry slot section extending from the proximal edge of the tubular sleeve towards the head and a locking slot section extending from the entry slot section towards the head. The locking slot section may have a first lateral wall that is oblique to the cavity axis and a second lateral wall that is parallel to the cavity axis.

Abstract: An oral care implement body to which a replacement head can be detachably coupled. In one embodiment, the oral care implement body includes a gripping portion having a shoulder, a stem extending from the shoulder along a longitudinal axis, and a boss protruding from an outer surface of the stem. The boss may have a locking rib section having an undercut surface that is axially spaced from the shoulder and a positioning rib section extending from the locking rib section to the shoulder. The undercut surface may circumferentially protrude from a first side surface of the positioning rib section. The locking rib section may extend along a first rib axis and the positioning rib section may extend along a second rib axis, the first rib axis oriented obliquely to the second rib axis.

Abstract: A connector capable of maintaining a state of being connected to a power feeding unit is provided. A blood pressure measurement device charging connector includes a main body including: a first member, a second member facing the first member, the second member including a protrusion including an end surface that makes contact with an inner peripheral surface of a pulling cuff provided on an inner peripheral surface of a curler mounted on the blood pressure measurement device, a rotational shaft configured to rotatably couple the first member and the second member, and a biasing member configured to bias the first member and the second member in an approaching direction; and a connection terminal connected to a power feeding terminal provided in the curler, the connection terminal being provided on the second member side in the first member.

Abstract: A fluid bladder includes multiple segment bladders that are each formed by folding one sheet in half in a width direction X extending along an artery passing through the measurement site, welding or adhering edge portions on a side opposite to the folding location for folding in half, and welding or adhering edge portions in a lengthwise direction Y. The multiple segment bladders are stacked in a width direction orthogonal to the measurement site and integrated, and the folding locations are arranged alternatingly on opposite sides in the width direction.

Abstract: The invention provides an electric toothbrush capable of changing a resonant frequency and vibration amplitude of an eccentric shaft. An electric toothbrush of the present invention includes a motor, an eccentric shaft with one end fixed to a rotation shaft of the motor, and a stemserving as a vibration transmitting component having a bearing for supporting the other end of the eccentric shaft for transmitting vibration generated in accordance with rotation of the eccentric shaft to a brush portion. In the electric toothbrush, the eccentric shaft is formed so that a gravity center position is movable at least in one direction among a direction in which a distance to a shaft center is changed and an axial direction.
