Problems solved by technology

There are a number of disadvantages associated with this approach
For example, if the plunger is released prematurely, the injection will stop and the intended dose will not be delivered
Also, the force required to push the plunger may be too high (for example, if the user is an elderly person or a child)
Also, aligning the injection device, administering the injection, and holding the device still during the injection may require dexterity, which some patients do not possess

Embodiment Construction

[0064] figure 1 is a simplified longitudinal sectional view of an exemplary embodiment of an autoinjector 1 according to the invention after assembly, showing the main assembly components. Figure 2A is a partially cutaway schematic perspective view of the autoinjector 1 . Figure 2B An exploded view showing all components of the autoinjector 1. Figure 2A , 2B The assembled autoinjector 1 is shown in more detail.

[0065] The autoinjector 1 includes a housing 2 . The housing 2 is designed in multiple parts. In particular, the housing 2 comprises a front housing 2.1 and a rear housing 2.2. The rear housing 2.2 is surrounded longitudinally by the front housing 2.1 and is adapted to close the open proximal end of the front housing 2.1. The housing 2 is adapted to hold a syringe 3 .

[0066] The syringe 3 may be a prefilled syringe or a prefilled drug container, and has a needle 4 provided at the distal end. The syringe 3 may be pre-assembled. In general, a protective ne...

Abstract

A syringe carrier(16) comprising: - a housing(16.0) adapted to receive a syringe (3) having a needle (4) encapsulated by a removable protective needle sheath (5), - two or more flexible arms (16.1) protruding inwards in a relaxed state and adapted to couple with the syringe (3) in a mounted position, wherein the flexible arms (16.1) are adapted to deflect radially outwards in a pre-assembled position of the syringe (3) in the syringe carrier (16), wherein in the mounted position the flexible arms (16.1) are allowed to return into the relaxed state due, in part, to an axial force (F2) operatingon the syringe carrier (16). The invention further relates to an autoinjector and a method of assembling the autoinjector.

Description

technical field [0001] The present invention relates to a syringe carrier for an autoinjector and a method of assembling an autoinjector. Background technique [0002] Administering an injection is a process that presents numerous mental and physical risks and challenges to both the user and the healthcare professional. Injection devices generally fall into two categories - manual devices and auto-injectors. In traditional manual devices, human power is required to drive the drug through the needle. This is usually done with a plunger that is pushed continuously during the injection. There are a number of disadvantages associated with this approach. For example, if the plunger is released prematurely, the injection will stop and the intended dose will not be delivered. Additionally, the force required to push the plunger may be too high (eg, if the user is an elderly person or a child). Also, aligning the injection device, administering the injection, and holding the in...
