Embodiment Construction

[0014] The present disclosure relates to a needle shield remover 10 for use, for example, in conjunction with a medicament delivery device. Before using the medicament delivery device, the injection needle 11 of the medicament container 13 ( figure 1 and FIG. 2 ) are protected by a needle shield 12, usually a so-called flexible needle shield (or FNS) or a rigid shield remover (or RNS). In this regard, the FNS is made of a soft elastic material, such as rubber, and the RNS is provided with a shell or housing made of a rigid material. In order to inject, the needle shield must be removed. In this regard, the medicament delivery device is provided with a needle shield remover 10 ( figure 1 ).

[0015] In the embodiment shown in the figures, the needle shield remover 10 includes a generally tubular body 14 extending in a longitudinal direction L ( figure 1 ). At the distal end of the main body 14 there may be provided an attachment element 16 which may be designed to cooperat...

Abstract

The present invention relates to a needle shield remover comprising a generally tubular body having a longitudinal extension, a grip element comprising a braided sleeve arranged to said body, said braided sleeve having an opening with such a diameter that a needle shield may be introduced, and wherein said braided sleeve has such a diameter that a friction fit is created between said braided sleeve and said needle sleeve when said needle cover is pulled for removing said needle cover.

Description

technical field [0001] The present invention relates to a needle shield remover. Background technique [0002] Many drug delivery devices designed for self-administration provide a pre-filled syringe or similar drug container which in turn is provided with a drug delivery member, such as an injection needle. In order to maintain the sterility of the injection needle, a needle shield is usually attached to the needle and surrounds the needle. One very common type of needle shield is the so-called flexible needle shield or FNS. FNS are usually made of a resilient material such as rubber and have an internal cavity in which the needle is placed. The dimensions of the cavity are chosen to provide a tight fit around the needle, thereby preventing any contamination of the sterile needle. [0003] However, this tight fit means there is a friction fit, so some force is required to pull the needle shield off the needle. Accordingly, many drug delivery devices are provided with a ...
