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;
- 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;
- an upper seal positioned toward the proximal end of the handheld portion relative to the needle port;
- and
- a lower seal positioned toward the distal end of the handheld portion relative to the needle port;
- and
- a drug delivery port configured to fluidly connect the drug vial to the needle port;
- wherein the needle assembly has a first needle position in which the needle assembly is fully disposed within the handheld portion, and a second needle position where at least a portion of the needle extends through the injection opening;
- and
- wherein the upper seal moves toward the lower seal as the needle assembly moves from the first needle position to the second needle 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 comprising:
- a needle with an interior lumen;
- and
- a needle port for receiving medication from the drug vial;
- and
- a drug delivery port configured to deliver medication from the drug vial to the needle assembly;
- removing a separation strip that prevents the handheld portion from moving relative to a trigger portion of the drug self-delivery device;
- placing the trigger portion adjacent to a user's skin at a location where the medication is to be administered, the trigger portion 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;
- wherein removing the separation strip further removes a non-conductive member from between a battery and an electrical contact, thereby completing an electronic circuit.
A drug self-delivery system 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;
- 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 portion 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;
- a battery;
- an electronic contact;
- and
- a non-conductive tooth positioned to separate the battery from the electronic contact.
