  • Publication number: 20240024199
    Abstract: An automated transfer and mixing device receives an injection device, a lyophilized drug vial and a diluent vial and transfers diluent from the diluent vial to the lyophilized drug vial and shakes or vibrates the lyophilized drug vial to reconstitute the drug. The device then transfers the reconstituted drug from the lyophilized drug vial to the injection device.

  • Patent number: 11833326
    Abstract: A fluid flow control valve includes a valve body with a fluid flow lumen therethrough and a valve member located within the fluid flow lumen. At least one of the valve body and the valve member is resilient and respectively sized for movement between a normally closed position in which the valve member and a fluid lumen surface are in sufficient annular contact to block fluid flow through the fluid flow lumen and an open position in which at least one of the valve body and the valve member flexes to a spaced apart position that allows the fluid flow between the valve body and the valve member. Downstream fluid pressure may contact the valve body to enhance sealing. A fluid absorbent member may also be employed with the valve body. Flow control devices, such as medical fluid injection devices, and methods may employ the valve.

  • Publication number: 20230285243
    Abstract: A transfer device for transferring a medical fluid from a vial to a medical fluid injection device includes a vial holder where a vial spike positioned within the vial holder is configured to enter a vial containing a medical fluid when the vial is inserted into the vial holder. An expansion chamber having an interior cavity is in fluid communication with the vial spike. A pressurized gas cartridge is positioned with the interior cavity of the expansion chamber, while a puncture tip is configured to puncture the pressurized gas cartridge when actuated by a user. The vial spike is also configured to be in fluid communication with an injection device attached to the transfer device.

  • Patent number: 11744777
    Abstract: A disposable fluid transfer and mixing device is disclosed and includes an injector support surface for receiving an injection device thereon. A lyophilized drug vial, a diluent vial and a syringe are also attached to the device. The device features fluid passageways and a manual valve that may be manipulated so that the syringe may be used to transfer diluent from the diluent vial to the lyophilized drug vial, for reconstitution of the drug. The valve may also be configured so that the reconstituted drug is transferred from the lyophilized drug vial to the injection device. An automated transfer and mixing device receives an injection device, a lyophilized drug vial and a diluent vial and transfers diluent from the diluent vial to the lyophilized drug vial and shakes or vibrates the lyophilized drug vial to reconstitute the drug. The device then transfers the reconstituted drug from the lyophilized drug vial to the injection device.
