Filling devices disclosed herein comprise a container having an open end, a first tubular attachment in fluid communication with the interior of the container, a second tubular attachment in fluid communication with the interior of the container, and a removable and re-installable closure or cap for the open end of the container. Hydration systems disclosed herein comprise a hydration bladder, a first hose section, a filling device in accordance with the embodiments herein, a second hose section, and a mouthpiece. The first hose section connects the hydration bladder to the filling device, and the second hose section connects the filling device to the mouthpiece.

A fluid storage bag comprising a storage bag sealed to a collapsible quick filling and self-sealing fill tube. After partially filling the storage bag, through the fill tube, to a desired level with water or other liquid the storage bag is inverted, thereby collapsing and effectively sealing the fill tube against itself. After use, the storage bag may be re-filled, or recycled. In one example, a 4 inch wide fill tube extends at 6 inches into the storage bag, with the last 5 inches creating a funnel to a 2 inch bottom width. In other examples air or other gas may be introduced through the fill tube; and as the bag is pressurized, the fill tube collapses and seals so that the bag may serve as a flotation device, air mattress, pillow or other device.

Embodiments include a cooling device for a medical device. The cooling device including a controller configured to receive data from one or more temperature sensors and a pump, configured to be operated by the controller, to circulate a cooling fluid through a cooling system and through fluid channels in the medical device. The cooling device is configured to be worn by a user and to be selectively coupled to the medical device by the user.

A hydration pack includes a main body, a strap, a bladder, a hydration tube, a first chain of magnets, and a second chain of magnets. The main body defines a storage compartment. The strap is coupled to the main body. The bladder is disposed in the storage compartment of the main body and configured to retain liquid. The hydration tube includes a proximal end coupled to the bladder and a distal end. The first chain of magnets is disposed on the strap. The second chain of magnets is disposed along a length of the hydration tube. The first and second chains of magnets are configured to connect by magnetic forces and disconnect by a force exceeding the magnetic force of the first and second chains of magnets.

An apparatus for carrying liquid includes a liquid container and an article of apparel. The liquid container includes a body, which is configured to removably receive the liquid, and a cap, which is configured to selectively seal the body. The article of apparel includes a pocket, which has an interior configured to removably receive the body. The article of apparel also includes a first opening and a second opening, each of which is in communication with the pocket interior. The first opening passes the liquid container, and the second opening passes the cap. The article of apparel further includes a flap, which is movably coupled to the article of apparel. The flap includes a third opening, which passes the cap. The flap is coupled to the article of apparel and movable between a first position, covering the first opening, and a second position, not covering the first opening.

A hydration device is provided that includes a sleeve that is worn securely on a limb, such as a forearm, of a user and contains a bladder for holding liquid such as water, sports drinks, etc. The bladder is removable and includes a refill port and a drinking valve. The hydration device can be designed to absorb impacts while being worn, yet is light-weight and flexible enough to conform to the user's body.

A fluid container can comprise a flexible bladder having an internal region for storing a fluid, a bladder opening at an upper end portion of the bladder for allowing passage of fluid in or out of the internal region, a lower rigid member secured to an outer surface of the bladder at a lower end portion of the bladder, an upper closure secured to the bladder over the bladder opening for selectively closing and opening the bladder opening, and a rigid, removable handle, wherein the handle has an upper end portion that is detachably coupled to the upper closure and a lower end portion that is detachably coupled to the lower rigid member.

A fluid containment system that comprises a fluid container with a top, with an orifice and a wall extending from the bottom, a junction cap that can be mechanically attached to the extended wall, a tube leading from the junction cap, and a mouth piece attached distal to the junction on the tube suitable for an end user to draw fluid from the fluid container.

An apparatus for material storage, transport and dispensation uses a bag constructed from one of more flexible plastic sheets and forming a chamber for holding material. Reinforced end regions of the bag may be removably coupled to one another to form a self-forming loop. A nozzle is coupled to the chamber by a flexible tube to form an attachment for dispensation of material from the chamber. The attachment may take the form of a shower head, for example.

A backpack and horizontal hydration reservoir combination is provided. The backpack does not extend downward beyond the middle of the back of the wearer, thereby eliminating the need for long shoulder straps and maintaining the weight of the hydration reservoir, housed within the backpack, in a horizontal orientation above the middle of the back.
