Sterilization Arrangement for Drug Delivery Device
A drug delivery system for injecting a medicament includes a housing defining a cavity, a container received within the cavity and configured to receive a medicament, the container comprising a stopper configured to move within the container and a closure, a drive assembly received within the cavity and configured to drive the stopper within the container, a needle actuator assembly received within the cavity and comprising a needle configured to be placed in fluid communication with the container, the needle moveable from a first position and a second position spaced from the first position, and a sterilizer received within the cavity and configured to sterilize at least one of the container, the drive assembly, and the needle actuator assembly upon activation of the drug delivery system.
1 . A wearable drug delivery system comprising:
a housing defining a cavity;
a container configured to be received within the cavity and configured to contain a medicament;
a first needle received within the cavity, the first needle configured to be placed in fluid communication with the container, the first needle having a first configuration in which the first needle is spaced from the container, and a second configuration different from the first configuration; and
a second needle in fluid communication with the first needle and configured to pierce skin of a patient and to deliver the medicament to the patient;
a button to initiate a drug delivery process; and
a sterilizer received within the cavity and configured to sterilize part of one or more of the container and the first needle upon initiation of the drug delivery process.
2 . The wearable drug delivery system of claim 1 , wherein the sterilizer comprises a source of ultraviolet light to sterilize the part of the one of the container and the first needle.
3 . The wearable drug delivery system of claim 1 , wherein the sterilizer comprises a light-emitting diode (LED) configured to emit light to sterilize the one or more of the container and the first needle.
4 . The wearable drug delivery system of claim 3 , wherein the sterilizer further comprises a power source operatively connected to the LED.
5 . The wearable drug delivery system of claim 4 , wherein the power source comprises a battery.
6 . The wearable drug delivery system of claim 3 , wherein the sterilizer further comprises a timer operatively connected to the LED and configured to shut off the LED after a predetermined amount of time.
7 . The wearable drug delivery system of claim 3 , wherein the at least one LED light source comprises a plurality of LEDs.
8 . The wearable drug delivery system of claim 3 , wherein the housing comprises a window configured to allow a patient to view a portion of the container.
9 . The wearable drug delivery system of claim 8 , wherein the window comprises a magnifying lens.
10 . The wearable drug delivery system of claim 3 , further comprising an indicator configured to convey a status of the drug delivery process.
11 . The wearable drug delivery system of claim 10 , wherein the indicator comprises an auditory, a tactile, or a visual indicator.
12 . The wearable drug delivery system of claim 10 , wherein the indicator is a visual indicator, and wherein the visual indicator is arranged within the housing and is visible through a window in the housing.
13 . The wearable drug delivery system of claim 10 , wherein the indicator is configured to indicate a pre-use status, a use status, and a post-use status.
14 . The wearable drug delivery system of claim 1 , further comprising an adhesive pad coupled to the housing and configured to be applied to a patient's skin and configured to adhere the wearable drug delivery system to the patient.
15 . The wearable drug delivery system of claim 1 , wherein the second needle is moveable between an extended position and a retracted position.
16 . The wearable drug delivery system of claim 1 , further comprising a drive assembly received within the cavity and configured to cause medicament to be expelled from the container.
17 . The wearable drug delivery system of claim 16 , wherein the drive assembly is configured to deliver medicament to a patient at a fixed pressure.
18 . The wearable drug delivery system of claim 16 , wherein the drive assembly is configured to deliver medicament at a fixed rate.
19 . The wearable drug delivery system of claim 1 , further comprising a sensor configured to detect when the button has been actuated and to cause the power source to supply power to the sterilizer.
20 . The wearable drug delivery system of claim 1 , wherein in the second position at least a portion of the first needle is received within the medicament container.
