A low-frequency treatment device includes a pad including a through hole and a pad side electrode on a rear surface, a holder disposed on the rear surface side of the pad so as to oppose the pad side electrode, a body including a body side electrode and detachably attached to the holder, and a wiring member configured to electrically connect the body side electrode and the pad side electrode. The wiring member includes a first end portion connected to the body side electrode, a second end portion connected to the pad side electrode, and a conductive portion, disposed such that a portion of the conductive portion extends through a through hole, for conducting electricity between the first end portion and the second end portion.

Low-frequency treatment device, body for low-frequency treatment device, and combination of pad and holder for low-frequency treatment device

A low-frequency treatment device includes: a pad configured to be attached to a body of a user; a holder configured to hold the pad; and a main body portion configured to be attached to the holder. The holder and the main body portion are engaged, with a clearance of a predetermined distance for arranging the pad being formed therebetween. Electrical conduction established between a pad-side electrode portion included on the pad and a main body portion-side electrode portion included on the main body portion by coming into contact with each other in the clearance of the predetermined distance. At least one electrode portion among the pad-side electrode portion and the main body portion-side electrode portion can perform movement in a direction of approaching and separating from the other electrode portion and is biased in the approaching direction.

The present invention includes a guiding engagement portion configured such that a holder and a main body portion for supplying a low-frequency pulse current to a pad engage in a state in which the main body portion is attached to the holder, and the holder and the main body portion are disengaged in a state in which the main body portion is removed. The guiding engagement portion is formed so as to allow the holder and the main body portion to engage by moving in a direction of approaching each other during the attachment, and during the removal, disengage the holder and the main body portion by restricting movement in a direction opposite to the movement direction during the attachment, and allowing the main body portion to move with respect to the holder in a direction intersecting the direction of approaching each other.

A piezoelectric pump is provided with an actuator containing a piezoelectric element and a vibrating sheet; a first diaphragm, positioned opposite the actuator, with a first connecting hole provided therein; a pump chamber formed by the space between the actuator and the first diaphragm; and a second diaphragm positioned opposite the first diaphragm. The part of the second diaphragm opposite the first connecting hole is provided with an opposing wall portion that prevents a fluid that has been introduced into the pump chamber via the first connecting hole from flowing back towards a suction side via the first connecting hole.

Piezoelectric pump and blood-pressure information measurement device provided therewith

In a fluid control device, a check valve includes a first valve housing and a first diaphragm. The first diaphragm defines a first valve chamber and a second valve chamber. An exhaust valve includes a second valve housing and a second diaphragm. The second diaphragm defines a third valve chamber and a fourth valve chamber. The check valve is opened and closed by a difference in pressure between the first valve chamber and the second valve chamber. The exhaust valve is opened and closed by a difference in pressure between the third valve chamber and the fourth valve chamber.
