Re-loadable auto injector

A reloadable auto injector comprising:

• a housing;
• a syringe assembly comprising
• a syringe with a needle, the syringe assembly being movably positioned in the housing between a first position in which position the needle is accommodated inside the housing and a second position in which position the needle protrudes outside the housing,
• a plunger rod driver configured to apply a force to a plunger rod to advance the plunger rod in the syringe for delivering at least one dose of medicament,
• a syringe driver configured to apply a force to the syringe assembly thereby moving the syringe from the first position to the second position;
• and
• a reload handle configured to reload the auto injector for injecting a further dose of medicament,
• wherein the reload handle is connected to the syringe assembly so that operation of the reload handle is configured to retract the syringe assembly to the first position and to simultaneously reload the syringe driver.

A reloadable auto injector with a housing for accommodation structures, the structures comprising:

• a skin sensor;
• a syringe assembly comprising
• a syringe with a needle,
• a plunger rod driver configured to apply a force to a plunger rod to advance the plunger rod in the syringe for delivering at least one dose of medicament,
• a syringe driver configured to apply a force to the syringe assembly thereby moving the syringe from a first position to a second position;
• a reload handle configured to reload the auto injector to deliver a further dose of medicament,
• wherein the reload handle is connected to the syringe assembly and the skin sensor so that an operation of the reload handle is configured to retract the syringe assembly to the first position and to simultaneously reload the syringe driver and release the skin sensor;
• and
• a syringe lock configured to lock the syringe assembly in the first position and the skin sensor configured to release the syringe lock upon engagement with the skin of a user,
• wherein the operation is configured to retract the syringe assembly to the first position, relock the syringe lock, and place the skin sensor in an unlocked position.
