A massage device is disclosed that is made by converting an existing breast pump using a massage adapter ring that allows for the easy conversion to and from a massage device to breast pump.

Embodiments of the invention relate to a pressure field stimulation device including a sheath having an integrated cup. The sheath and cup are together formed of (or consist of) a single piece of material. The pressure field stimulator has a cup and a driver, where the driver is configured to vary a volume of the cup. The pressure field stimulator has a housing that has an opening therein with an edge on which a portion of the cup rests when installed. The sheath is tightly bound to the housing such that a driver can make contact with the cup. In some embodiments, the pressure field stimulator has a shaft portion, which may include a second stimulation device. The sheath can be bound over the shaft portion as well as the pressure field stimulator housing.

Disclosed embodiments provide an improved stimulation device. Embodiments of the improved stimulation device include a cup and a driver. The cup has a cavity surrounded by a rim. In use, a user positions the rim such that an opening to the cavity is over an area to be stimulated (for example, the clitoris). A sealed-, or substantially-sealed, chamber is formed by the cavity walls and the user's skin (surrounding the clitoris). A pressure field is generated in the chamber without generating a pressure below a reference pressure, which is gauge pressure reading of zero. In some embodiments, this is achieved by a driver configured to vary a volume of the cavity in such a way that the varied volume is not larger than an initial volume. In some embodiments, the stimulation device is a sex toy. In some embodiments, the stimulation device is a medical device.

An air pressure massager includes at least one pressure field generating device. The pressure field generating device includes a chamber with at least one first opening, a connecting rod member connected to one end of the chamber, an eccentric member connected to the connecting rod member, a driving unit connected with the eccentric member, a control device configured to activate the drive unit, and an accessory. The first opening is configured to be placed on a portion of a human body. The driving unit drives the eccentric member to move to drive the connecting rod member to move, such that a volume of the chamber is changed to generate a pressure field for stimulating the human body. The pressure field generated in the chamber directly towards the portion of the human body. The pressure field is adjusted by a positive pressure mode and/or a negative pressure mode.

Embodiments of the present invention relate to an improved stimulation device. Embodiments of the improved stimulation device includes a cup and a driver. The cup has a cavity surrounded by a rim. The driver comprises a plate disposed on an underside of the cup, a cam disposed adjacent to the plate, and a motor mechanically coupled to the cam. The driver comprises a cam pin affixed to the cam, and a bearing rotatably disposed on the cam pin. The bearing is mechanically coupled to a lifter. The lifter is mechanically coupled to a linear bearing, enabling a smooth reciprocating back-and-forth motion from the rotation of the motor. A top of the cup swells and unswells during an operation cycle of the driver.

Stimulation devices are disclosed. An example apparatus includes a housing including a chamber. The housing defines an opening to the chamber. The example apparatus includes a flexible material protruding from the opening and configured to sealingly engage a portion of a body of a user including a clitoris. The example apparatus includes a drive unit disposed in the housing. The drive unit is to cause a volume of the chamber to alternate between a first volume and a second volume, the alternating volume of the chamber to cause pressure in the chamber to modulate between positive pressures relative to an ambient pressure and negative pressures relative to the ambient pressure. The modulated positive pressures and negative pressures are to be applied to the portion of the body via the opening.

An example stimulation device includes a housing, a longitudinal axis of the housing being an axis of longest extension along a length of the housing from a first end to a second end of the housing, a first portion of the housing defining an opening to a chamber, a central longitudinal axis of the first portion of the housing extending through the opening, the central longitudinal axis of the first portion of the housing disposed at a non-perpendicular angle relative to the longitudinal axis of the housing; and a drive unit disposed in the housing, the drive unit to cause a volume of the chamber to change to cause pressure in the chamber to alternate between positive pressures and negative pressures relative to an ambient pressure, the alternating positive and negative pressures to be applied to a portion of a body of a user including a clitoris via the opening.

A stimulation device is provided in accordance with one embodiment. The stimulation device includes a chamber which has a flexible wall portion. A drive unit of the stimulation device is in physical communication with the flexible wall portion so as to cause deflections of the flexible wall portion in opposing directions, thereby resulting in a changing volume of the chamber. The changing volume of the chamber results in modulated positive and negative pressures with respect to a reference pressure. An opening of the stimulation device is for applying the modulated positive and negative pressures to a body part. The stimulation device includes a control device for controlling the drive unit.

The present invention relates to a canister, a suction apparatus and a tissue expansion apparatus comprising same, and provides, according to one aspect of the present invention, a suction apparatus comprising: a housing having an inlet and an outlet; a pump disposed in the housing and suctioning air flowing in via the inlet; a first flow line for connecting the inlet and an inflow port of the pump; a second flow line for connecting an outflow port of the pump and outside air; a control valve disposed in the housing and provided with a first port connected to the first flow line, and a second port connected to the second flow line; a battery disposed in the housing and supplying power to the pump; and a control unit for controlling the pump and the control valve.
