Stimulation devices are disclosed. An example 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.

A massage device with knocking and sucking functions includes a housing including a driving member, a telescopic member connected with the driving member in a transmission way, and a through-hole formed at an end thereof so that the telescopic member can pass through the through-hole to be exposed outside; a soft massaging member surrounding around the through-hole and connected with the telescopic member; a soft suction nozzle detachably connected with the soft massaging member and formed a chamber with an opening therebetween, when removing the soft suction nozzle, the driving member drives the telescopic member to reciprocate up and down to drive the soft massaging member to reciprocate up and down, to knocking massage the human body; when connecting the soft suction nozzle with the soft massaging member, the soft massaging member reciprocates up and down to squeeze air in the chamber, to sucking massage the human body.

An elastic electric-heating cupping jar includes a hollow convoluted jar body made of an elastic material, and further includes an electric heating device, where the electric heating device includes an electric heating wire and a connection fixture that are electrically connected to each other; the connection fixture includes a circuit board and a pluggable port; two poles of the electric heating wire and a wire connecting end of the pluggable port are electrically connected to the circuit board; and the electric heating device is encapsulated in a wall at a plane of a maximum jar body diameter, a center of the electric heating wire is located on or near an axial cross section with the maximum jar body diameter, and the pluggable port faces toward an outer surface of the jar body and is electrically connected to a controller outside the jar body and/or an external power supply.

A mechanical CPR device having one or more of a piston, a driving component configured to extend the piston toward a patient's torso and retract the piston away from the patient's torso, a controller configured to control the driving component to at least compress the patient's torso by extending the piston from a reference position to a depth and retracting the piston from the depth to the reference position, and a contact member such as one or more of a pressure pad and a suction cup attached to the end of the piston. The contact member can include a semi-adhesive material that has low adhesiveness when the controller controls the driving component to compress the patient's torso less than 60 times per minute and high adhesiveness when the controller controls the driving component to compress the patient's torso more than 60 times per minute.

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 provides devices and methods for creating and/or maintaining patency of the upper airway passage. The device is configured to fit under the chin of a subject at an external location corresponding approximately with the subject's internal soft tissue associated with the neck's anterior triangle. The device includes structural elements designed to optimize comfort, compliance and seal achieved through minimizing the pressure variation along the contact surface of the therapy device.

Disclosed embodiments provide an improved stimulation device, including 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 driver is configured to vary a volume of a cavity of a cup from a first volume to a second volume. The cup returns from the second volume to the first volume, in between intermittent varying from the first volume to the second volume, due to a buckle region wall of the cup springing out. The varying of the volume creates a pressure field in the chamber. The springing out produces a “thud” force, also used interchangeably with “thump” force.

Embodiments of the invention relate to a device including a pressure field stimulator and a roller massager. The pressure field stimulator has a cup and a driver, where the driver is configured to vary a volume of the cup. The roller massager comprises a flexible sheath and a roller disposed adjacent the flexible sheath. In some embodiments, an enclosure is disposed around the roller where the enclosure includes an opening through which the roller protrudes. In some embodiments, the roller is disposed on a threaded shaft, mechanically coupled to a motor, within the enclosure. The sheath is tightly bound to the enclosure such that the roller presses on the sheath.
