Problems solved by technology

[0006] However, there may be situations where a user wishes to temporarily keep a used needle on the device, for example when a suitable container for safe disposal of the needle is not immediately available
[0007] If the cap is sized to accommodate the needle, the overall length of the pen injector is long and the device can be awkward for the user

Embodiment Construction

[0042] The following will refer to the attached image 3 to 9 to describe the present invention in detail.

[0043] The invention is suitable for any reusable syringe, such as a multidose device adapted to receive a drug cartridge and adapted to receive a needle. figure 1 with 2 The trigger and dose button are optional features. exist figure 1 with 2 In , the syringe is shown with a single cap capable of housing the needle. A specific example of a needle would be a needle conforming to ISO11608-2:2012, which specifies sterile needles for single use, double use, needle-based injection systems (NIS) meeting the provisions of ISO11608-1 requirements and test methods.

[0044]In one aspect of the invention, the syringe is provided with two caps, one cap sized to accommodate a needle and the other cap being shorter and possibly incapable of accommodating a needle. Before replacing the longer cap with the shorter cap it is necessary to remove the needle, which in any case sho...

Abstract

A re-usable, multi-dose injection device having a housing suitable for receiving a medicament cartridge, and also suitable for receiving a needle, and comprising a cap (22) that can be removably attached to a needle receiving end of the housing, wherein the cap (22) has an adjustable length.

Description

technical field [0001] The present invention relates to substance delivery devices, and in particular to caps for devices including injection devices such as auto-injectors and pen injectors. Background technique [0002] Automatic injection devices are commonly used in the field of medicine to deliver measured doses of medication to a user. Self-administering patients can safely use these injection devices because of their user-friendly design, but in some cases these injection devices can be used by trained individuals. Automatic injection devices may be designed to be carried by the user who uses them at any time, in which case these injection devices need to be as small and unobtrusive as possible to improve user compliance. Autoinjection devices for self-administration of injected medications include single-dose and multi-dose reusable and disposable auto-injectors and pen-injectors (e.g., insulin pens) that are suitable for a wide range of mainstream containers, inclu...
