Techniques and devices for extending a piston, 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, an external piston spacer may be attached to an outward surface of the inner piston to extend the length of the piston. In another aspect an internal bayonet sleeve may contact one or more locking rods at various positions, enabling adjustment of the length of the inner piston. In yet another aspect, a piston adapter may be removably attached to the end of the piston. 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.

A dildo assembly comprising a housing, and a dildo, having a base at one end and a tip at the opposite end, attached at its base to the housing and comprising a plurality of hinged segments, wherein the plurality of hinged segments are moveable between a first configuration, in which the dildo is curved, and a second configuration in which the dildo extends substantially straight away from the housing.

Provided is a container for drinking liquid comprising: a) a body; b) a first cap for removably attaching to the body, the cap having an opening configured to allow liquid to travel from inside of the body to outside of the body; c) a piston configured to move inside the body as the liquid leaves the body, the piston separating the liquid and air inside the body; wherein liquid leaves the body and moves to the outside of the container through the opening in the first cap.

Systems, devices and methods adaptable for use with or as a toilet seat to assist in a bowel movement. The systems and devices may include one or more projections extending upward to be desirably positioned relative to body parts while the user is seated on a toilet seat having the one or more projections.

An instrument is applied to body tissue of a body part to produce vibration to thereby reduce pain of injection or other pain producing stimulus. The device has a frame, and a source of vibration connected to the frame. A removable tip is connectable to the frame which has a distal end that is connected to the source of vibration when the tip is connected to the frame, to thereby vibrate the distal end when the source of vibration is activated. At the distal end of the tip are mutually facing arms which define an opening between them. Each arm forms a projection which extends at an angle from the arm. The projections are shaped to fit the body part so that the arms and projections are sized and dimensioned to position, retain, and transmit vibration to the body part in a position proximate the opening.

The disposable Cupping device is useful for wet and dry cupping therapeutic treatment. It consists of a Barrel like cup, plunger with at least one projections, and a Locking mechanism.

Foot care devices include a battery-powered vibration motor disposed inside a water-tight housing, a foot treatment element attached to the upper surface of the housing, and surface immobilizing suction cups attached to the bottom of the housing to inhibit positional movement of the device during use. Foot treatment elements have exfoliating pumice, massaging protuberances, and/or cleaning bristles and vibrate during operation of the motor. Cushioning pads between the upper surface of the housing and the attached foot treatment element reduce rattling noises during operation of the motor. Foot treatment elements also have drain holes extending therethrough and the housing has a drain channel for draining water off the upper surface. The devices can also have one or more stabilizing platform extending therefrom. Foot pressure applied to the platform during operation further reduces positional movement. Foot care kits can have a plurality of interchangeable foot treatment elements.

Provided is a container for drinking liquid comprising: a. a reservoir for holding liquid, the reservoir made from a material that shrinks as liquid leaves the reservoir, b. an opening for the liquid to leave the reservoir and exit the container; and c. a one way valve configured to be actuated by a person sucking the opening; wherein when the person sucks, the one way valve opens and the liquid leaves the container while the reservoir shrinks to compensate for volume of the liquid that left the container. In another embodiment, provided is a container for drinking liquid comprising: a) a housing in a shape of a phallus, the housing having a body and a cap, inside of the body of the housing having a reservoir for a liquid, the cap configured to be removably attached to the housing; and b) a channel in the cap configured to carry liquid from inside of the housing to outside of the container: wherein the reservoir is tilled by removing the cap, and pouring the liquid into the reservoir, and the liquid is consumed through the channel. Provided is a container for drinking liquid comprising: a) a body; b) a cap for removably attaching to the body, the cap having an opening configured to allow liquid to travel from inside of the container to outside of the container; c) a cup for holding liquid placed inside of the body, the cup maintained in proximity to, a top of the body; Wherein liquid leaves the cup and moves to the outside of the container through the opening in the cap. Also provided are mannequins in assembly with such containers.

An elevation device used in the performance of cardiopulmonary resuscitation (CPR) includes a base and an upper support pivotably coupled to the base. The upper support is configured to elevate the individual's upper back, shoulders and head when pivoted. The upper support is expandable lengthwise. The upper support includes a neck support that is configured to support the individual's spine in a region of the individual's C7 and C8 vertebrae throughout elevation of the upper back, shoulders and head.
