Abstract
A drug self-delivery device comprising a body portion containing a drug vial and a needle assembly, where the body portion is slidably engaged to a trigger portion. When engaged by a user pressing the trigger portion against the user's flesh, the needle assembly relative to the drug vial so as to align a needle port with an integral drug delivery port connected to the drug vial thereby allowing fluid flow of medication through the needle. Seals engaged by a penetration spring prevent loss of medication and prevent the need for direct connection between the needle assembly and the drug vial.
Claims20
A drug self-delivery device comprising:
- a handheld portion having a proximal end, a distal end and a longitudinal axis therebetween;
- a trigger portion in slidable engagement with the distal end of the handheld portion and defining an injection opening;
- a drug vial disposed within the handheld portion, the drug vial containing a fluid medication and having a first vial position wherein the drug vial is distal from the trigger portion and a second vial position wherein the drug vial is proximate to the trigger portion;
- a needle assembly comprising:
- a needle having an interior lumen to allow the flow of medication;
- a needle port for receiving medication from the drug vial;
- and
- one or more seals to reduce leakage of medication delivered from the drug vial toward the needle port;
- a drug delivery port configured to deliver medication from the drug vial to the needle assembly when the drug vial is in the second vial position.
A method for administering medication stored within a drug self-delivery device comprising the steps of:
- grasping a handheld portion of the drug self-delivery device having a proximal end, a distal end and a longitudinal axis therebetween and at least partially housing:
- a drug vial containing a fluid medication to be administered;
- a needle assembly having a needle port for receiving medication from the drug vial and one or more seals to reduce leakage of medication delivered from the drug vial;
- a drug delivery port configured to deliver medication from the drug vial to the needle assembly;
- placing a trigger portion of the drug self-delivery device adjacent to a user's skin at a location where the medication is to be administered, the trigger portion being in slidable engagement with the distal end of the handheld portion and defining an injection opening;
- and
- pressing the handheld portion toward the trigger portion such that a portion of the needle extends through the injection opening.
A drug self-delivery system comprising:
- a handheld component having a proximal end, a distal end and a longitudinal axis therebetween;
- a trigger component in slidable engagement with the distal end of the handheld component and defining an injection opening;
- a drug vial disposed within the handheld component, the drug vial containing a fluid medication and having a first vial position wherein the drug vial is distal from the trigger portion and a second vial position wherein the drug vial is proximate to the trigger portion;
- a needle assembly comprising a needle and a needle port, the needle assembly having a first position where the needle assembly is entirely disposed within the handheld component and an extended position where the needle is at least partially extending through the injection opening;
- a drug delivery port configured to deliver medication from the drug vial to the needle assembly when the needle assembly is in the extended position;
- and
- a communication module configured to send an alert to a remote communication device to indicate a state of the drug self-delivery system.
