Abstract: A plunging apparatus for a syringe is applied to connect with a driving assembly of an injection device and a medicine vial. The plunging apparatus has a pushing element connected with a connection element by a unidirectional check element. The rear end of the connection element is connected with a pushing rod. The front end of the pushing rod has an ejection element and a spring. A threaded collar is mounted around the pushing rod, and an injection rod is mounted in the pushing rod. The connection element is inserted into a rear opening of the medicine vial. Engagement hooks on the ejection element can be pressed by medicine vial. The spring forces the ejection element to move forward to push the pushing element to abut the piston. Accordingly, the medicine vial can be used immediately after being combined with the injection device without discharging air manually.

Abstract: The present invention relates to an injection device for subcutaneous or intramuscular injection of a pharmaceutical formulation characterized by a yield value, said device comprising, a longitudinally continuous hollow element forming a reservoir for the pharmaceutical formulation, said longitudinally continuous hollow element having a first cylindrical hollow element having an internal diameter (d1), in continuum with a second tapering element that tapers from the internal diameter (d1) to an opening with a diameter (d2) over a length (l), wherein d1 ranges from 2.6 mm to 3.0 mm, d2 ranges from 0.71 mm to 1.01 mm and l ranges from 0.91 mm to 1.41 mm; a needle adapted to be attached to the opening of said second tapering element; and a plunger rod for insertion in the said cylindrical hollow element having a thumb rest at one end and a stopper at the other end.

Abstract: A portable device for cutting a capsule which has been filled with a drug formulation is configured to allow for the accurate alignment of the capsule in the capsule holder and includes a blade shaped to cut the upper portion of the capsule so as to open and dispense the drug formulation without any spillage, and the cut end is disposed capably without falling back in the medication. The device operates accurately with different capsule sizes, even with smaller capsule size when dose content is low, and provides a reliable and precise technique for splitting capsules.

Abstract: A portable device for cutting of capsules filled with a drug formulation and simultaneously forming a passageway for dispensing the drug formulation.
