Problems solved by technology

[0011] However, it has been found that such a configuration with e.g. longitudinal ribs causes storage problems of the syringe body: a syringe body cast according to the above principles tends to tilt if placed on a flat surface with its flange surface

Embodiment Construction

[0053] figure 1 A schematic view of a syringe body 1 with a piston 2 is shown, which together form a medicament syringe 4 . The syringe body 1 is made of transparent plastic, in this example a cycloolefin polymer or copolymer. It comprises a cavity 6 with cylindrical walls. The wall is substantially closed at the first end face 8 , but the liquid located in the cavity 6 can also be forced out there via the cone 10 . This is achieved by squeezing the piston 2 inwards so that the piston head 12 , which is round and in seamless contact with the wall of the cavity 6 , exerts pressure on the liquid.

[0054] For inserting the piston 2 into the cavity 6, the cavity is open on the second end face of the cylinder. In order to press the piston 2 inwards, it has, on the side opposite the piston head 12 , a pressing surface 14 which is normally actuated by means of the user's thumb. To apply counter pressure, a collar is cast around the circular orifice of the cavity 6 flange 16 fo...

Abstract

The present invention relates to a syringe body for a drug or cosmetic syringe and a method for administering a drug or cosmetic, the syringe body comprising a cylindrical cavity having: a first end face with a cone; a second open end surface into which the piston is inserted; and a flange for the finger, which is arranged in the circumferential region of the open end face, the flange for the finger having, on the side facing the cone, a non-slip element for preventing slipping of the finger during injection.

Description

technical field [0001] The present invention relates to a syringe body for a drug or cosmetic syringe and a method for administering the drug or cosmetic product, said syringe body comprising a cylindrical cavity having: a first end surface with a taper; the second open end face for insertion into the piston; and a flange for the fingers, which is arranged in the circumferential region of the open end face, wherein the flange for the fingers has an anti-slip element on the side facing the cone for Prevent slipping of fingers during injection. Background technique [0002] A drug injector refers to a medical device for applying (injecting) liquid or fluid drugs or cosmetics (so-called injections, which are generally also simply referred to as fluids within the scope of the present disclosure). A syringe generally includes a syringe body having a cylindrical cavity and a plunger that moves therein. On the end face of the cylinder there is usually a cone, possibly also a thre...
