Problems solved by technology

However, this solution can be considered inherently unsafe due to the impaired safety function of the safety device
In addition, the process of using the safety sleeve after an injection is uncomfortable for the patient since the edge of the safety sleeve presses against the skin at certain locations

Embodiment Construction

[0035] figure 1 is an isometric view of a syringe including a safety device, and figure 2 is a side view of a syringe including a safety device according to a first embodiment.

[0036] The syringe (2) comprises a syringe body (3) configured as a hollow cylinder. The syringe body comprises a distal region (12) having a distal end (4). A piercing tool (5) is arranged at the distal end (4). This piercing tool (5) is connected to the cavity in the syringe body (3) through a hole in the distal region (12), so that during use of the syringe (2) the injected medium can pass through the cavity and pass through the piercing tool ( 5). The distal region (12) is designed as a conical end piece with a smaller outer diameter than the syringe body (3). The syringe also has a transition region in which the outer diameter of the syringe body (3) transitions into the outer diameter of the end piece.

[0037] A safety device (1) for a syringe (2) for avoiding stab wounds comprises a sle...

Abstract

The 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, the safety device comprising a needle extending in the axial direction (X) and at least partially surrounding the piercing A tool and a syringe body, wherein the sleeve member includes at its distal end a contact portion which, during use of the syringe, at least partially contacts a patient's skin and defines an opening surface. The safety device is characterized in that the opening surface at least partially has a subregion enclosing an angle α with the axial direction (X), wherein the angle α is in the range between 10° and 80°.

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, the piercing tool comprising a and a sleeve member of the syringe body, the sleeve member having a contact portion at its distal end that contacts at least a portion of the patient's skin when the syringe is in use and defines an open face. Background technique [0002] Universal safety devices for avoiding stab wounds are known in the art. It is advantageous to use such a safety device in particular in prefilled syringes. The handling of this syringe is very simple, as there is no need to transfer the medium into the syringe prior to administration. Also, even in an emergency, the chances of using the wrong medication are very low. Such syringes are now the primary packaging material of choice for vaccines and countless other pharmaceuticals. These syringes are usually mad...
