Abstract: A disposable double pointed injection needle has a needle hub to which a thin needle cannula is permanently fasten and which needle hub can be mounted on to a syringe comprising a dose setting and injection mechanism and a cartridge containing a liquid medicine to be injected subcutaneously into a human body. The needle hub is provided with a safety shield guided on the outside surface of the needle hub. The safety shield is urged in a direction away from the needle hub by a spring located between the needle hub and the safety shield. The safety shield has a number of protrusions guided in guiding tracks on the outside surface of the needle hub. The guiding tracks are designed such that the safety shield during injection is moved towards the needle hub, and after injection is moved away from the needle hub by the spring and locked in an irreversible position where the safety shield covers the needle cannula and prevents accidental needle stick injuries.

Abstract: The system is a semi automatic needle magazine mounted on, or as a part of a medication delivery system. It comprises of a plurality of confinements each containing an injection needle. The needle magazine can be rotated in order to position one injection needle at the time in front of a cartridge located in the medication delivery system. Once the injection needle is located in front of the cartridge the needle magazine can be pushed towards the medication delivery system whereby the injection needle penetrates the septum of the cartridge.

Abstract: The needle assembly comprises a hub with a thread fitting the thread of a standard medical injection device. The hub is mounted with a cannula. The cannula has a proximal end that can penetrate the septum of a cartridge and a distal end that can penetrate the skin a patient. A protective sleeve surrounding the cannula is mounted at the distal end of a conical spring, which is mounted on the distal surface of the hub. The protective sleeve is locked in position near the distal surface of the hub. The protective sleeve is released when the needle is fully inserted into the patients skin, and slides along the needle cannula toward the distal end as the needle is withdrawn from the patient. When the protective sleeve reaches the distal end of the cannula it locks in position preventing further access to the distal end of the cannula.
