The device for moulding frozen confectionery articles comprises a metering hopper connected to a volumetric metering device comprising a metering chamber and a metering element dispensing a predetermined volume of ice cream into passing containers by means of a metering nozzle. As the hopper is pressurized, the metering chamber is filled without the formation of air pockets in the aspiration phase, which makes it possible to manufacture moulded articles of hard ice cream.

A portable, patient-controlled medication delivery system includes an infusion pump and a catheter assembly. The infusion pump retains a treatment fluid and provides a drive mechanism for delivering the treatment fluid to a patient via the catheter assembly. The infusion pump includes a fluid reservoir, a dosage chamber, a displacement piston displacable within the dosage chamber, a charge flowpath providing fluid communication between the fluid reservoir and the dosage chamber, and a passive flow restrictor positioned in the charge flowpath. An elastic member is also positioned in the infusion pump to exert an elastic displacement force on the displacement piston, which expands the dosage chamber and draws the treatment fluid from the fluid reservoir into the dosage chamber at a charge flow rate controlled by the passive flow restrictor. When an opposing manual displacement force is exerted on the displacement piston, the dosage chamber contracts and discharges the treatment fluid from the dosage chamber to the treatment site.

A portable, patient-controlled medication delivery system includes an infusion pump, a catheter assembly and an extension tubing set. The infusion pump retains a treatment fluid and provides a drive mechanism for delivering the treatment fluid to a patient. The catheter assembly has a medicine catheter which penetrates directly into the treatment site of the patient and the extension tubing set has an extension tube which connects the medicine catheter and infusion pump. The infusion pump includes a fluid reservoir, a dosage chamber, and a displacement piston displacable within the dosage chamber. An elastic member is also positioned in the infusion pump to exert a displacement force on the displacement piston. The elastic member is alternately transitionable between a more stressed position and a less stressed position. The elastic member elastically displaces the displacement piston in a first direction to expand the dosage chamber and draw the treatment fluid from the fluid reservoir into the dosage chamber when the elastic member transitions from the more stressed position to the less stressed position. The displacement piston is manually displaced in a second direction to contract the dosage chamber and discharge the treatment fluid from the dosage chamber to the treatment site when the elastic member transitions from the less stressed position to the more stressed position.

Molded ice confectionery articles are prepared by delivering a hard ice confectionery composition to a metering device chamber under a pressure greater than atmospheric pressure, keeping the composition in the device chamber under a pressure greater than atmospheric pressure and metering the composition from the composition from the device chamber under a pressure greater than atmospheric pressure into a mold member positioned in an environment for freezing the composition metered into the mold member for obtaining a molded frozen article. So operating allows the composition delivered to the device chamber to have a percentage of frozen water to total water of at least 50%.

A method and system for creation of compression-molded edible ice objects from a pulverized ice mass, where said method involves feeding of the pulverized ice mass from a container to one or more cylinders in an inlet magazine and movement of the one or more cylinders of the inlet magazine to a transfer position. Furthermore, the method also comprises transferring of the ice mass from the one or more cylinders to at least one form in a form unit by compression to form one or more edible ice objects, and movement of the at least one form to a release position, where the edible ice objects are released from the at least one form.
