A substance delivery device (autoinjector) for use with a container (such as a syringe) containing the substance includes: a body arranged to house or hold the container; a plunger which is movable with respect to at least a portion of the body, the plunger being arranged to act upon the container so as to move the container with respect to the portion of the body; wherein the plunger is also arranged to expel at least a portion of the substance from the container; and wherein the device includes elements for adjusting the amount of substance to be expelled from the container. The device can also have elements for priming the container, and can accommodate containers of different size or shape.

Described is an autoinjector comprising a front case having a first rib and a second rib, and a rear case telescopically coupled to the front case and having latch arms adapted to engage the first rib and the second rib. When the front case is in a first position relative to rear case, the latch arms are engaged to the first rib. When the latch arms disengage the first rib, the front case translates to a second position relative to the rear case, an axial distance between the front case and the rear case increases relative to the first position, the latch arms engage the second rib.

An injection needle assembly (50) for an injection device, comprising: a) a needle cannula (3) attached to a needle hub (4) and defining a pointed tip at a free end (3a, 3b), and b) a needle cover (10, 10a, 10b) forming an axially extending elongated flexible enclosure accommodating the needle cannula (3). The needle cover (10, 10a, 10b) is configured to axially collapse and become penetrated by the needle cannula (3) when a penetration force is applied to the needle cover. The needle cover (10, 10a, 10b) defines a shaft section (11a) and a bulb section (11b). The shaft section (11a) encircles the needle cannula (3) and extends axially from the needle hub (4) to the bulb section (11b). The shaft section (11a) comprises wall areas of minimum wall thickness t.sub.1 whereas the bulb section (11b) comprises wall areas (17a, 17b) having a wall thickness t.sub.2 larger than said minimum wall thickness t.sub.1. The shaft section (11a) comprises one or more reinforcing ribs (16), each reinforcing rib extending non-parallel to the needle axis so as to at least partly encircle the needle cannula (3), wherein each reinforcing rib (16) divides adjoining annular collapse regions (15) of the shaft section (11a).

The present disclosure relates to a cap assembly for a medicament delivery device. The cap assembly comprises: a cap body arranged to be mounted to a proximal end of a medicament delivery device for protecting and for removing a medicament delivery member shield. The cap body has an inner cap structure defining a channel extending along the central axis of the cap body, and a gripping member configured to be received in the channel. The gripping member is radially flexible and has a first leg, a second leg, and a connecting portion extending between the first leg and the second leg. The first leg and the second leg each has a proximal portion that is radially flexible and extends distally from the connecting portion. Each proximal portion has an inclined section extending radially inwards in an axial direction away from the connecting portion. Each of the first leg and the second leg has a distal portion extending from the inclined section, the distal portions being radially flexible and extending radially outwards in an axial direction away from the proximal portions to allow the gripping member to receive a medicament delivery member shield between the distal portions. The gripping member and an inner wall of the channel are configured to engage to retain the gripping member in the inner cap structure. Each distal portion is provided with a medicament delivery member shield gripper configured to engage with a medicament delivery member shield when the gripping member engages with the inner wall of the channel and the gripping member has received a medicament delivery member shield causing the proximal portions and the distal portions to flex radially inwards.

A syringe cover obscures a patient's observation of needle insertions for medical procedures. Obscuring the needle insertion from the patient reduces the psychological fear associated with needles. The syringe cover includes a tubular sleeve, a collapsible sleeve, and a viewport opening. The tubular sleeve covers the fluid reservoir barrel to hide the fluid drawn from or injected into the patient from the patient's view. The collapsible sleeve obscures the needle of the syringe from the patient's view. The collapsible sleeve is pressed against the patient's body when the needle penetrates the patient's skin. The collapsible sleeve deforms as the needle is inserted into the patient's body such that the collapsible sleeve does not obstruct the insertion of the needle. The viewport allows the medical practitioner to view the volume of fluid within the fluid reservoir barrel of the syringe.
