A portable massage ball assembly for facilitating a user to massage their back while seated in a vehicle includes a clasp that is closable around a support such that the clasp can be attached to a seat in a vehicle. A retractor is coupled to the clasp and a cable is integrated into the retractor. Additionally, the cable is drawable outwardly from the retractor. A ball is coupled to the cable such that the ball can be positioned between the seat in the vehicle and a user. In this way the user can massage their back with the ball.

Examples of the disclosure include a universal suction cup for a cardiopulmonary resuscitation device having a first circular member extending from a piston-facing surface, and a second circular member concentric to the first circular member extending from the piston-facing surface, the second circular member having a diameter that is less than the first circular member. Example of the disclosure also include suction cups with rigid members to reduce the amount of force necessary to attach the suction cup to a patient. Examples of the disclosure also include a mechanical compression device which can detect the type of suction cup attached to a compression member and activate particular features or settings based on the attached suction cup.

According to some embodiments, a device configured for self-administered therapy comprises at least two base members, each base member configured to be secured to a surface for mounting the device of said surface, a shaft configured to secure to the at least two base members and extend between the at least two base members, and at least one therapy member configured to be secured relative to the shaft, wherein the at least one therapy member is configured to rotate relative to the shaft during use, wherein the at least one therapy member is configured to be contacted by a user and configured to rotate during use.

According to some embodiments, a method of promoting hair growth or hair stimulation in a subject comprises applying vacuum or suction using a handpiece assembly along a targeted portion of the subject's skin surface where hair growth or hair stimulation is desired and providing at least one treatment material to said targeted portion of the subject's skin surface, wherein the application of vacuum or suction helps promote hair growth or stimulate hair.

An anti-drowsiness device includes a head cover; an electroencephalograph, which is formed on the head cover, the electroencephalograph receiving the brain-waves all the time and generating a sleep-detection signal when a specific frequency, which shows drowsiness, is received, and an electrostimulator, which is formed on the head cover, the electrostimulator generating electrostimulation when receiving the sleep-detection signal.

Examples of the disclosure are directed to mechanical compression devices that can adjust a location of a compression position relative to a patient. One or more of the mechanical compression devices can adjust the compression position in an adjustment plane that is generally perpendicular to a patient. Some of the mechanical compression include support columns that have actuators that can be set asymmetrically to adjust the compression position and/or can be tilted relative to the backboard to adjust the compression position. Other examples includes mechanical compression devices that have multiple actuators that can be used to adjust the compression position as well as provide compressions.

Techniques and devices for extending a piston and/or compression unit, for example connected to a medical device such as a mechanical CPR device, to accommodate different sized patients, are described herein. In some cases, a piston of a mechanical CPR device may include an inner piston at least partially slidable into an external piston sleeve. In one aspect, some aspects, the piston includes sleeves which can move relative to each other to extend the piston. In additional aspects, the compression mechanism may also extend downward toward the patient. In all aspects, the change in length of the piston may be detected and used to modify movement of the piston, for example to more safely perform mechanical CPR.

Provided is a multi-use container. The container can be used for drinking a liquid by sucking a nipple to actuate one-way valve. Alternatively, the container can be used as a dildo by using a glans shaped cap. The container can be used to drink liquids from all sorts of angles. The container can also include a piston.

A video augmentation system is disclosed. The system includes a sensor configured to detect haptics signals associated with user manipulation; a camera configured to record images associated with the user manipulation; and a processor configured to combine the haptics signals and the images into a combined haptics/images file.

A negative-pressure massage machine includes a main body and an embedded filter. The main body has a panel with an installing hole. The embedded filter includes a hollow cylinder and a filter element disposed in the hollow cylinder. The hollow cylinder is assembled or removed corresponding to the installing hole from the outside of the panel. Therefore, the ventilation may be performed with a filter assuredly when a user is operating, and the degree of dirtiness of the filter may be easily viewed and the filter may be replaced conveniently.
