Embodiment Construction

[0033] figure 1 and figure 2 A syringe (2) comprising a safety device (1) for avoiding stab wounds is shown, figure 1 is the isometric view, figure 2 is a cross-sectional view. The syringe (2) comprises a syringe body (3) configured as a hollow cylinder. The syringe body has a distal region (10) comprising a distal end (4). A piercing tool (5) is arranged at the distal end (4). The piercing tool (5) is connected to the cavity in the syringe body (3) through a hole in the distal region (10), so that the medium to be injected can pass through the piercing tool (5) from the cavity when using the syringe (2). wear out. The distal region (10) is configured with a conical end piece having a smaller outer diameter than the syringe body (3). The syringe also has a transition region (26) in which the outer diameter of the syringe body (3) transitions into the outer diameter of the end piece. In addition, a protrusion (27) is arranged on the distal region.

Abstract

The invention relates to a safety device for a syringe for avoiding stab wounds, said syringe having a syringe body and a piercing means arranged on the distal end of the syringe body. The safety device comprises a sleeve element that extends along an axial direction (X) and at least partially encloses the piercing means and the syringe body, and an inner element which is at least arranged at least in sections inside the sleeve element and surrounds the piercing means. Said safety device is characterised in that the inner element comprises a rim section and a piercing means protection sectionsurrounding the piercing means. Said rim section can be arranged on a distal end of the syringe body, the safety device is secured to the syringe body, and the piercing means protection section can beremoved from the rim section before using the syringe.

Description

technical field [0001] The present invention relates to a safety device for avoiding stab wounds for a syringe having a syringe body and a piercing tool arranged at the distal end of the syringe body, said safety device comprising a sleeve element and an inner element, the sleeve The barrel element extends in the axial direction (X) and at least partially surrounds the piercing tool and the syringe body, and the inner element is at least partially arranged inside the sleeve element and surrounds the piercing tool. Background technique [0002] Universal safety devices for avoiding stab wounds are known in the art. Especially the use of such a safety device in prefilled syringes is advantageous. Handling of this syringe is very simple as media does not have to be transferred into the syringe before use. Furthermore, the possibility of delivering the wrong drug is very low, even in emergency situations. They are now the primary encapsulation material of choice for vaccines ...
