Abstract: Point protection and method for use at hypodermic puncture needles characterised by that the point protector's active protection function is effected by a thin walled tube that externally or internally is closely fitted to the puncture needle (1) so that a supporting, evenly distributed normal pressure on the thin walled tube arises which substantially increases its capacity to sustain the forces that after accomplished tissue penetration may be expected to affect the protector, without embarrassing deformation, and by that prevent accidental scratch, chafe and/or stab injuries caused by the sharp needle point inclusive tissue damages at punctured tissue for instance at the inside punctured blood vessels, the so-called endothelium.

Abstract: Ergonomic handle for a syringe intended for puncturing blood vessel walls and establishing blood path connections. The typical syringe comprises a tube body and a needle body. The handle prevents unintended displacements between the tube body and the needle body and permits placement of the thumb and forefinger at the side and the tip of the puncture needle for more precision in use.

Abstract: An accessory for temporary, contamination-free holding of closing stoppers used for syringes and other medical care devices, where the accessory comprises a stopper designed for coupling to a recess in another existing stopper or a carrier that can be combined with a stopper. The carrier has a lower part, which may be designed as a substitute for an existing stopper; a mid-piece, which is inserted in or over an existing stopper; a rider for placing over a curved surface such as a syringe body; or a carrier-foot for fastening onto suitable surfaces.

Abstract: Method of direction control consisting in producing one or more parallel reference lines (7,8) that may be manipulated in such a way that their directions become parallel to the intended direction and with the help of plane mirrors making images (9,10) of the reference lines and images (12,13) of the object the straightening up of which is to be controlled. Implement for use at the method.
