Abstract

The present invention relates to an auto injector, e.g. a disposable auto injector, that can be safely operated for automatic injection of a dose of medication by the recipient of the medication, having a housing for accommodation of a container with at least one compartment for accommodation of a medicament to be injected and a needle mounting site for user mounting of a needle covered by a needle cap before injection, and a needle shield that is accommodated in the housing in a retracted position before mounting of the needle and that is configured to be automatically moved forward to a protruded position by a needle shield driver upon mounting of the needle and removal of the needle cap.

Description

technical field [0001] The present invention relates to syringes that can be safely operated by a recipient of a medicament for automatically injecting a dose of medicament. Auto-injectors can be disposable. Background technique [0002] Autoinjectors are well known in the art. Autoinjectors are provided with varying degrees of automation, from automatic penetration only or automatic injection only to fully automatic functions including penetration, injection, withdrawal and protection of the needle. [0003] Some auto-injectors are used to deliver to the patient so-called ready-to-use medications packaged in a syringe, ampule or syringe in a liquid state, which can be stored for a long period of time before use. [0004] Other drugs must be mixed with a liquid immediately before injection because the effect of the drug deteriorates and is lost very quickly after mixing with the liquid. [0005] WO 2006 / 080893 A1 discloses an autoinjector with a needle shield. A needle w...
