Abstract: A cannula device having a base body made of plastic, on which a cannula is held, and having a guard element that can be moved relative to the base body into a second position, in which the cannula tip is exposed for the use of the cannula device, from a first position, in which, in the delivered state of the cannula device, the cannula tip is covered to protect the user from injury. The guard element is movable, after use of the cannula device, back into a third position in which the cannula tip is covered to protect a user from injury, and the guard element is irreversibly locked to the base body by a third fixing device including a first latching protrusion protruding from the base body and at least one first latching receptacle, associated with the first latching protrusion in at least one side wall of the guard element.

Abstract: A cannula for deposition of an object in the body of a living organism, comprising a cannula holder having a first handle and a sleeve with a second handle surrounding said cannula holder at least in part and being axially movable in relation thereto, and having a mandrin extending inside the cannula, said object such as a medical long-term preparation, identification carrier or capsule containing a radioactive substance being depositable by a relative movement between the mandrin and the cannula receiving the object.

Abstract: Proposed is a needle (12) with a sharpened point (14) at the tip and a needle holder (16) at the rear end holding the needle, a mandrel (24) which can be displaced inside the needle, and optionally a protective cap (18) enclosing the needle point and detachably attached to the needle holder, with which objects (10) such as longterm preparations, identification tags, or the like are to be inserted in the body of a living being. To ensure that the object is unequivocally fixed in position inside the needle, the object is arranged between a closure toward the tip of the needle and, for example, a constriction (20) toward the handling end. The closure is preferably a stopper which is carried along with the object when the latter is inserted.

Abstract: A process for the production of a split cannula (10), and such a cannula having predetermined break lines (18) which run in the lengthwise direction (12) and preferably are diametrically opposite, are proposed, with the predetermined break lines (18) being produced by non-metal-cutting shaping.

Abstract: A cannula for puncturing blood vessels comprising a beveled cannula tip and a cannula holder wherein the cannula is fixedly mounted, the cannula holder having at its rear end a flexible tube and being at least partially surrounded by a wing-shaped handle and a protector cap covering the cannula tip, wherein the protector cap and the handle are formed as a unit, which is slipped onto the said holder from the cannula tip, the said cannula holder comprises a locking collar and the said handle comprises a snap-in groove whereby said locking collar is locked in said snap-in groove when the unit is mounted on the cannula holder and the said cannula holder is provided with a shoulder facing said tube at a distance from said handle.
