Abstract: An electric dental flosser apparatus includes a drive mechanism for rotationally oscillating a drive shaft 4 about its own axis and a floss holder 3 mounted on the drive shaft 4 so as to be oscillated rotationally by the drive shaft 4. A flosser element 5 is stretched taut on the floss holder in a direction perpendicular to an axial direction of the drive shaft 4 so as to pass across an extension line A of the drive shaft 4 or a position adjacent thereto.

Abstract: In an electric toothbrush in which a disk-like brush body is reciprocally rotated about an axis intersecting at a predetermined angle in a line extended in a longitudinal direction of a grip portion, a head portion put into user's mouth is made smaller or thinner, a rotation shaft of the brush body and a head portion are enabled incline at an optional angle with respect to the grip portion, and transmission efficiency of driving force is increased. For there purposes, an eccentric member having an eccentric shaft is fixed on a driving shaft of a motor, a joint portion formed at a first end portion of a lever member is made point contact with the eccentric shaft, so that the rotation movement of the eccentric shaft is converted to swing movement of the first end portion of the lever member.

Abstract: An object of present invention is to provide an eye drop which causes no uncomfortable irritation upon instillation and shows favorable long-term storage stability of CPB-I. The eye drop which comprises CPB-I and a polyhydric alcohol, preferably the polyhydric alcohol having a carbonyl value of 5 &mgr;mol/g or lower, can be provided.

Abstract: A massaging apparatus including a head unit, a pair of housings and a pair of arms. The head unit is configured to massage a body of a user. The pair of housings are connected to opposite sides of the head unit respectively and extend in opposite directions from the head unit. The pair of arms are configured to be held by the user and provided to the pair of housings respectively. The pair of arms are flexible.

Abstract: A roller massaging apparatus includes a massaging portion having a plurality of bar-shaped rotatable rollers. The rollers are circumferentially mounted to the massaging portion at a certain interval. The roller massaging apparatus also includes a driving mechanism for rotating the massaging portion around an axis thereof and a stimulating member disposed at an upper side of the massaging portion. The stimulating member is pushed up by the rollers. A mutual positional relationship between the massaging portion and the stimulating member is changed by moving as least one of the massaging portion and the stimulating member.

Abstract: A massager comprises a handle, a roller rotatably supported at one end of the handle and having a peripheral surface adopted to contact a human body, and a vibration generating unit for giving a vibration to the roller. A head for incorporating the vibration generating unit therein is formed at the end of the handle. The roller is disposed on an outer surface of the head to which the vibration is applied. The present massager can selectively provide a vibration massage of applying a vibration to a skin through the roller rolled along the skin, and a vibration massage of applying a vibration to a skin through a peripheral portion of the head pressed against the skin. As a result, it is possible to provide an adequate vibration massage in accordance with the circumstances.

Abstract: An air massaging device having at least one inflatable air bag adapted to be laid against a portion of the human body. The device includes an air pump generating a pressurized air and a distributor valve which has an open position of feeding the pressurized air to the air bag and a closed position of allowing the pressurized air to be discharged from the air bag to the atmosphere in order to repeat inflating and deflating the air bag. A single pressure sensor is disposed upstream of the distributor valve to monitor a pressure level developed on the side of the air pump. A control circuit is included to activate the air pump on a time-period basis in order to give a desired pressure level to which the air bag is inflated. The control circuit operates to provide one or more initial inflation cycle and subsequent inflation cycles alternated by deflating cycles.

Abstract: An air massaging apparatus utilizes a plurality of inflatable air bags of elongated configuration which are arranged in side-by-side relation along a line and supplied with compressed air from a pump to inflate. A distributor is provided to channel the compressed air from the pump selectively to the air bags for inflating the air bags one after another sequentially in a predetermined primary direction along the line of arrangement in such a manner as to inflate at least one air bag at a time while allowing the compressed air to escape from the remaining air bags. The distributor is controlled to inflate the air bags temporarily in a reverse order over a limited number of the air bags during an overall operation of sequentially inflating the air bags in the predetermined primary direction.

Abstract: A bedsore-preventing air mattress controller provided with an air pump for generating a magnetomotive force in a plurality of stages proportional to the feed air amount of the pump, and with an electric switch for changing over the magnetomotive force of the pump and integrally assembled with an air shut-off valve for discharging and halting air, whereby the controller arrangement is simplified to effectively reduce the required number of parts for lowering manufacturing costs.

Abstract: A bedsore preventing apparatus comprises an air mattress having at least two groups of pneumatically expandible and contractible cells respectively communicating with one another in each of the groups, each of said cells in one of the groups being positioned between adjacent ones of the cells in the other group, an air pump for supplying air under a pressure to the cells in each group through each of conduit pipes for the respective groups, and a valve means provided at least in one of the conduit pipes and cyclically actuated for changing over its mode between open and closed modes so that, upon activation of the apparatus, the cells in at least one of the groups sequentially expand and contact to sufficiently change inflation and deflation pattern of the cells of the air mattress for avoiding continuous support at any specific positions of patient's body lying on the mattress and preventing patient's bedsore at such positions.
