Problems solved by technology

Another problem with current connectors is that the connector is usually screwed into the thread manually and the screw-in torque can fluctuate in a wide range, for example in the range of 12 Ncm to 56 Ncm, preferably 12 Ncm to 80 Ncm

Embodiment Construction

[0038] Figure 1 shows a part of a syringe body 1 comprising a syringe cone 3 with a distal opening 5. Only the upper part of the syringe in the region of the syringe cone 3 is shown in the entire syringe body 1 . The syringe body 1 is preferably made of a rigid plastic such as cycloolefin copolymer (COC) or cycloolefin polymer (COP). A connector for the syringe, such as a connector 10 for a sleeve, is arranged around the syringe cone 3. The connector 10 is here a sleeve with an internal thread 12, but is not limited thereto. The connecting piece 10 is here formed as a separate component with respect to the syringe body 3. In the embodiment according to FIG. 1 , the syringe body as the first component and the connecting piece as the second component are only mechanically connected to each other, for example the connecting piece 10 is slipped over the syringe body and locked in the undercut 14 , that is, the connecting piece is held in a form-fitting manner. The separate com...

Abstract

The invention relates to a syringe which includes a syringe body, a syringe cone having a distal opening, and a connection arranged in the region of the syringe cone, wherein the syringe body includesa first material and the connection includes a second material, and wherein the first material is different from the second material and the second material is a softer material than the first material.

Description

technical field [0001] The invention relates to a syringe having a syringe body and a syringe cone, the syringe cone comprising a distal opening and a connection, in particular in the form of a thread, arranged in the region of the syringe cone, wherein the syringe body is formed by a second A material is formed and the connector is formed of a second material. Background technique [0002] A number of patents have disclosed syringes with connections for different connectors (Konnektoren), which are mounted manually on top of the syringe. [0003] Such a syringe is shown for example by US 2013 / 079276 A. A syringe body is known from US 2013 / 079276 A, in which a transport cap, an IV port or an injection needle can be screwed into a thread above the syringe cone. The syringe cone can be protected if, for example, the transport cap is screwed into the thread. [0004] DE 202 158 07 U1 discloses a syringe with a thread in the region of a Luer-Lock connection, the thread being ...
