  • Publication number: 20230088439
    Abstract: The present disclosure provides methods of preparing a medical solution. In some aspects, the medical solution can be prepared from mixing a first liquid with a second liquid or mixing a solid component with a liquid in an autoinjector. In some aspects, the heat released from the mixing can promote solubility of a dry medicament in the solution.

  • Publication number: 20220223750
    Abstract: A photovoltaic device is provided. It comprises at least two electrical contacts, p type dopants and n type dopants. It also comprises a bulk region and nanowires in an aligned array which contact the bulk region. All nanowires in the array have one predominant type of dopant, n or p, and at least a portion of the bulk region also comprises that predominant type of dopant. The portion of the bulk region comprising the predominant type of dopant typically contacts the nanowire array. The photovoltaic devices' p-n junction would then be found in the bulk region. The photovoltaic devices would commonly comprise silicon.

  • Publication number: 20220001112
    Abstract: A mixing device configured to hold two containers, each having a separate medicament component disposed therein. A fluidic channel is provided that upon creating fluidic communication with each container once seals about each container are opened. Then a transfer mechanism can transfer the medicament components from one container to the other container until ready to be delivered or transferred through the fluidic channel through a delivery assembly.

  • Patent number: 11116903
    Abstract: Contemplated herein is a medication mixing device which can include a housing having therein a first chamber containing a first medicament component and a second chamber provided containing a second medicament component provided with a sealing structure selectively isolating the first chamber from the second chamber. The sealing structure can include a first sealing component having a first sealing interface and a second sealing component having a second sealing interface wherein a first compression force can be applied to the first and second sealing components causes the sealing interfaces to form a seal. The first compression force can then be configured to allow the first sealing component and the second sealing component to maintain at least one degree of freedom with respect to one another.

  • Patent number: 11007320
    Abstract: A portable auto-injector configured to store a dry medication separately from a liquid component, wherein removal of a cap operates a first actuation mechanism which opens a valve between a first and second chamber that are slidably movable relative to each other and thus allows for the initiation of a mixing step prior to injection. An extendable needle guard is provided over the delivery assembly which prevents premature injection as well as inadvertent sticks or other cross contamination of a needle. The needle guard can also form part of a secondary trigger mechanism which injects the mixed components after the mixing stage is complete.

  • Publication number: 20200139048
    Abstract: A portable dual chamber auto-injector configured to store a dry opioid antagonist medicament separately from a liquid component, wherein a user actuated mixing system comprising a movable component to create a fluidic pathway between the first and second chambers and release a portion of energy from a pre-stored energy to drive a displacement mechanism into the first chamber and displace the liquid component into the second chamber and solubilize the opioid antagonist. A needle assembly in fluid communication with the second chamber can be used to transfer the solubilized opioid antagonist.

  • Patent number: 10569017
    Abstract: A telescoping portable drug mixing and delivery device configured to store a dry medication separately from a liquid component, wherein a tensile force applied between the housing and a cap opens a valve and causes displacement of a fluid from a first chamber to a second chamber while simultaneously mixing the fluid with a dry medicament prior to injection. An extendable needle guard is provided over the delivery assembly which prevents premature injection as well as inadvertent sticks or other cross contamination of a needle. The needle guard can also form part of a secondary trigger mechanism which injects the reconstituted drug after the mixing stage is complete.
