The present disclosure discloses a suction toy, including a shell, a printed circuit board (PCB), an actuating device, a piston, and a power supply. The shell is provided with a piston chamber; the piston chamber is communicated with an air inlet channel and an air outlet channel; the air inlet channel is provided with an air inlet, and the air outlet channel is provided with an air outlet; the shell is provided with a suction mouth; and the air inlet and the air outlet are both communicated with the suction mouth. Therefore, compared with the prior art, the suction toy can generate larger air flow and provide users with a better experience, and also has the advantages of difficulty in damage and longer service life.

A method of treating cardiovascular disease in a patient includes generating, by an implantable stimulator configured to be implanted beneath a skin surface of the patient, stimulation sessions at a duty cycle that is less than 0.05 and applying, by the implantable stimulator in accordance with the duty cycle, the stimulation sessions to a location, within the patient, that is associated with the cardiovascular disease. The duty cycle is a ratio of T3 to T4. Each stimulation session included in the stimulation sessions has a duration of T3 minutes and occurs at a rate of once every T4 minutes.

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 of a user’s body to be stimulated (for example, the clitoris). A sealed-, or substantially-sealed, main chamber is formed by the cavity walls and the user’s body (skin surrounding the clitoris). A pressure field is generated in the main chamber. The device may further include an auxiliary chamber that is pneumatically connected to the main chamber via a conduit. An auxiliary chamber volume adjuster allows the user to vary the volume of the auxiliary chamber, which varies a total combined volume of the pneumatically connected main chamber and auxiliary chamber. The change in total volume causes a change in pressure experienced by the user. This allows the user to adjust the pressure based on comfort and pleasure as per user preferences.

A visual assistance system or distance and location detection system is provided. The system comprises a sensor detecting distance of objects in a user's path and alerting the user when an object is within a designated proximity to the user. The system further comprises a location detection system using GPS technology that tracks the user's location and issues an alert to the user or other individual when the user's location exceeds the boundaries of a designated safe zone.

A weighted massage roller including a plurality of end rounds, wherein each of the plurality of end rounds has an end round diameter, a plurality of middle rounds, wherein at least one of the plurality of middle rounds is located adjacent to each of the plurality of end rounds, and wherein each of the plurality of middle rounds has a middle round diameter, and a center round located adjacent to another of the plurality of middle rounds, wherein the center round has a center round diameter, and wherein the center round diameter is larger than the middle round diameter of each of the plurality of middle rounds and the end round diameter of each of the end rounds is larger than the center round diameter.

An adult toy article including a main body including a rear, central and front portions and defining a tip end and a rear end, and including an inner body and an outer body overlaying at least a portion of the inner body, each of the inner body and outer body defining a rear, central and front portion corresponding to the rear, central and front portion of the main body. The central portion of the inner body may define at least in part an elongated shape. The front portion of the inner body may define a tapering cone-shape with a rounded front end. The outer body may overlay at least a portion of the inner body, the outer body being sufficiently transparent to view at least a portion of the inner body there through.

A massage roller includes a cylindrical tube body having an inner surface; a supporting core attached on the inner surface of the cylindrical tube body to form a cylindrical cavity; and a filing unit disposed inside the cylindrical cavity to improve the strength of the massage roller.

A device for treating a user includes a housing having apertures. The housing has application areas including a convex top surface, a concave bottom surface, a convex rear surface, convex side surfaces and rounded protrusions extending away from the housing. A vibrational source is located in the housing to produce vibration at the application areas. A switch is in operative communication with the vibrational source to control operation of the vibrational source.

The present disclosure includes various examples for cooling electronics within a medical device while preventing or reducing the risk of an interior of the medical device being contaminated with a pathogen. The present disclosure includes a medical device having an air deflector to deflect potentially contaminated air from infecting a patient or caregiver. The present disclosure also includes medical devices with disinfectant devices installed to disinfect air either before entering the medical device or before exiting the device. Other examples of the present disclosure include medical devices that are sealed from outside air and fluids, and which may include a cooling device on an exterior surface which may be cleaned and/or removed after each use.

Disclosed are methods, circuits, devices, assemblies and system for treatment of a highly concentrated therapeutic solution of salts and minerals in water. According to some embodiments, a system for solution treatment, integral or otherwise functionally associated with a pool, may include a combination of filters, heaters, antimicrobial reactors and injectors.
