Problems solved by technology

Many newer generation injection devices are often not cylindrical, and in many newer devices, other parts of the device go beyond the needle hub, making it impossible to load the needle into the injection device without first removing it from the box

Embodiment Construction

[0021] The present invention provides systems and methods for fitting needle guard assemblies to ampoules and injection devices. Typically, a needle guard assembly includes a needle 510 mounted on a guard 500 (see image 3 ). Such as figure 1 As shown, needle guard 10 may be substantially cylindrical and have an inner wall surface 20 . In one embodiment of the present invention, a plurality of protrusions 30 protrude radially inwardly from the inner surface 20

[0022] Needle seat 100 is used for receiving needle cover 10 (see figure 1 ). Such as figure 1 and 2 As shown, hub 100 may be substantially cylindrical and have an outer wall surface 110 . A plurality of grooves or slots 120 are distributed in the outer surface 110 . The slot 120 has a first end 122 and a second end 125 . Slot 120 has a first portion 130 forming a channel substantially parallel to cylindrical axis 1000 of hub 100 . Although the first portion of the slot 130 is shown as a rectangular section, ...

Abstract

A needle mounting system and methods for mounting a needle assembly on a needle mount are disclosed. The needle mounting system includes a needle hub having protrusions extending radially inward. A needle mount has a plurality of slots to receive the protrusions. The slots have a first portion that defines a passageway substantially parallel to a longitudinal axis of the needle mount and a second portion substantially perpendicular to the axis. The needle hub and mount provide a method wherein a needle assembly may be mounted on an injection device without completely rotating the needle hub relative to the needle mount.

Description

field of invention [0001] The present invention relates generally to injection devices and, more particularly, provides methods and systems for loading a needle into an injection device or into an ampoule that can be loaded into an injection device. Background technique [0002] Injection devices, also known as dosers, have greatly improved the lives of patients who must self-administer pharmaceuticals and biologics. Dosers can come in many forms, including simple disposable devices that are smaller than an ampoule with an injection device, or they can be highly complex devices with a large number of functions. Regardless of the form of the doser, dosers have proven to be of great help in helping patients self-administer injectable medicines and biologics. Dosers can also greatly assist health care workers in administering injectable medications to patients who cannot administer their own injections. [0003] Pen injection devices, in particular, have proven to be an accur...
