Embodiment Construction

[0033] Figure 1-4 Shown is a syringe (2) comprising a safety device (1) for avoiding poking according to various embodiments. The syringe (2) comprises a syringe body (3) designed as a hollow cylinder. The syringe body comprises a distal region (8) having a distal end (4). A piercing mechanism (5) is provided at the distal end (4). The piercing mechanism (5) is connected to the cavity of the syringe body (3) through a hole in the distal region (8), so that when the syringe (2) is applied, the medium to be injected can pass from the cavity through the piercing mechanism (5) Appear. The distal region (8) is designed as a tapered end portion with a smaller outer diameter than the syringe body (3). The syringe also includes a transition region (29) where the outer diameter of the syringe body meets the outer diameter of the tip portion. Furthermore, a protrusion (28) is provided in the distal region.

Abstract

The present invention relates to a safety device for avoiding stab wounds for a syringe comprising a syringe body and a piercing mechanism arranged at the distal end of the syringe body. The safety device includes a sleeve element extending in the axial direction (X) and at least partially surrounding the piercing mechanism and the syringe body, and also includes a sleeve element disposed on the distal region of the syringe body and locking the safety device in the axial direction (X). A collar element comprising at least one guide projection which engages in at least one guide rail of the sleeve element. The safety device further comprises a cap element arranged to be at least partially seatable on the sleeve element and by means of which the sleeve element can be locked with respect to movement of the syringe body relative to the sleeve element.

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 mechanism arranged at the distal end of the syringe body, the safety device comprising a The sleeve element of the threading mechanism and the syringe body, also includes a harness element arranged on the distal end region of the syringe body and locks the safety device in the axial direction (X), the harness element includes at least one guide protrusion, The guide protrusion engages in at least one guide rail of the sleeve element. Background technique [0002] Common safety devices for avoiding stab wounds are known. The use of such a safety device is particularly meaningful for prefilled syringes. Handling of this syringe is very simple as there is no need to transfer media into the syringe prior to application. In addition, the possibility of using the wrong drug is low, even in an emergency. The syringe is currently the...
