One aspect relates to a device for producing a bone cement paste from a monomer liquid and a cement powder as parent components of the bone cement paste and for delivering the mixed bone cement paste, the device having a cartridge having a cylindrical interior. The interior of the cartridge is closed on the front side except for a delivery opening for expelling the bone cement paste. A delivery plunger is arranged in the interior of the cartridge. The cement powder is arranged in the interior of the cartridge. A closure is arranged on the front side of the delivery plunger. The closure closes the delivery opening when the delivery plunger is pressed against the front side of the interior of the cartridge. The closure blocks a further movement of the delivery plunger so that the delivery plunger is spaced from the front side of the interior of the cartridge at least in some areas and a dead volume remains in the interior of the cartridge when the delivery plunger is pressed against the front side of the interior of the cartridge.

A bone cement applicator comprising a cartridge with an internal space. The cartridge has a head with a dispensing opening for expulsion of bone cement, a dispensing plunger, a receptacle mobile in the cartridge, and a mixing rod with a mixer fastened to it and arranged in the internal space of the cartridge. The mixing rod is detachably connected, on a side opposite from the mixer, to a front side of the receptacle that faces the cartridge head. When the mixing rod is detached from the receptacle and the receptacle is propelled in the direction of the cartridge head the mixing rod can be pushed into the receptacle. A method is also disclosed for production of a bone cement using the bone cement applicator.

The present invention relates to a dispenser for viscous materials that includes a static mixer, a first and second receptacle R.sub.1 and R.sub.2 for a first and second viscous material, connected in fluid communication with the static mixer, a first and second actuator configured for discharge of receptacle R.sub.1 and R.sub.2, an electrically or manually operable drive and a mechanical or hydraulic power transmission configured to translate drive motion into first and second actuator motion.

An individual frozen drink dispenser includes a housing having a base configured to support a blender cup, a dispensing chamber disposed above the blender cup and configured to support a frozen beverage container containing frozen ingredients suitable for preparing a frozen drink, at least one dispensing mechanism configured to move from a pre-dispense position to a dispense position in which the dispensing mechanism drives the frozen ingredients from the frozen beverage container into the blender cup, and a drive mechanism coupled to the housing and configured to drive the movement of the dispensing mechanism from the pre-dispense position to the dispense position. A method of preparing a frozen drink is further disclosed.

Described is an apparatus for preparing baby formula using a liquid concentrate solution. The apparatus includes a housing with a cavity for receiving and holding a container liquid concentrate solution. A motor is attached with the housing for forcing liquid concentrate solution from the container and into a mixing chamber. A pump and a water tank are also included. A spray head is attached with the housing. The spray head includes a plurality of spray jets in fluid connection with the pump for receiving water from the water tank and dispensing water from the spray jets into the mixing chamber. Finally, the mixing chamber receives the liquid concentrate solution and water, such that when the water and the liquid concentrate solution are introduced into the mixing chamber, the water and liquid concentrate solution mix into a baby formula and are dispensed from an outlet in the mixing chamber.

A system and apparatus for opening and emptying a bag of material includes a base having a pair of opposed sides and a central aperture through which material may flow. The system includes a pair of opposed doors rotatably mounted on a pair of door shafts, the edges of the pair of opposed doors forming an opening and a plurality of piercing blades pivotally mounted to the base on a pivot rod, the blades capable of pivoting to pierce said bag. The system further includes a cutting blade mounted transversely below the opening of the opposed doors, the cutting blade capable of linear motion across the opening.

A device for storage of a monomer liquid and a cement powder as starting components of a bone cement dough and for mixing the starting components, and for dispensing the mixed bone cement dough. The device includes a receptacle in which a monomer liquid container is arranged and a cartridge containing the cement powder. A feed plunger is arranged in the receptacle. A dispensing plunger is arranged between the monomer liquid container and the cement powder in the cartridge. The feed plunger can be punctured by a rod when motion of the feed plunger is blocked, whereby the dispensing plunger is propelled by propelling the rod further through the blocked and punctured feed plunger. Also provided are an extrusion device for propelling a feed plunger and a dispensing plunger of a device for mixing of a bone cement dough, and a method for the production of a bone cement dough.

A bone cement applicator comprising a cartridge with an internal space. The cartridge has a head with a dispensing opening for expulsion of bone cement, a first thread, a dispensing plunger, a threaded tube having a counter thread engaging the first thread, a receptacle mobile in the threaded tube, and a mixing rod with a mixer fastened to it and arranged in the internal space of the cartridge. The mixing rod is detachably connected to the receptacle and is guided through a feedthrough in the dispensing plunger and is supported in the feedthrough so as to be axially mobile. When detached from the receptacle, the mixing rod can be pushed into the receptacle when the receptacle is propelled in the direction of the cartridge head. A method is also disclosed for production of a bone cement using the bone cement applicator.

One aspect relates to a device for producing a bone cement paste from a monomer liquid and a cement powder as parent components of the bone cement paste and for delivering the mixed bone cement paste. The device has a cartridge with a cylindrical interior. The interior of the cartridge is closed at a front side apart from a delivery opening for discharging the bone cement paste. In the interior of the cartridge a delivery plunger is arranged which is pushable in the direction of the delivery opening. The cement powder is arranged in the interior of the cartridge between the delivery opening and the delivery plunger. A hollow cylinder is arranged at a front side of the delivery plunger facing the delivery opening. The hollow cylinder is open at its front face facing the delivery opening and extends from the front side of the delivery plunger at least 3 mm into the interior of the cartridge.

The present invention involves the use of a small profile device for preparation and/or delivery of cold slurry into the human body. The cold slurry can be generated within the device itself or within a separate small chamber, both of which produce a cold slurry using a cooling source and an injectable fluid. The delivery device provides continued agitation to the fluid/slurry through rotation and/or vibration of blades within the device. The fluid/cold slurry is cooled/kept cool through the use of an external cooling device, such as a cooling sleeve, that at least partially surrounds the delivery device. The cooling sleeve can cool or maintain the temperature of the cold slurry through a number of mechanisms. The cold slurry can be delivered using a device in accordance with the present invention to any tissue inside the body, including subcutaneous fat, visceral fat, and brown fat.
