摘要： A medication injection pen, including a housing, a dose set knob (DSK) comprising an internal key, and a dose stop member engaging the dose set knob. Rotation of the dose set knob to set a medication dose causes rotation of the dose stop member with respect to the dose set knob, and when the dose set knob is rotated to a last dose setting position, the dose stop member rotationally abuts the internal key thereby preventing further rotational movement of the dose set knob in a dose setting direction.

摘要： A method for creating a sterile connection with a fluid in a container. The container has a sealing member sealing a first end of the container, and a barrier sealing a chamber in fluid communication with the sealing member. The method includes providing a valve sleeve assembly that includes a flexible sleeve having a barrier portion at an end of the flexible sleeve, a hollow first penetrator disposed within the flexible sleeve, and a hollow second penetrator at least partially disposed within the first penetrator. An interior of the flexible sleeve is sterile. The method also includes piercing the barrier portion and the barrier with the first penetrator, and displacing the second penetrator relative to the first penetrator and the sealing member to pierce the sealing member and establish the sterile connection with an interior of the container.

摘要： A medication injection pen, including a housing, a push button, a dose set knob (DSK) including at least one internal tooth and a ring of DSK ratchet teeth, a driver including at least one external tooth and a ring of driver ratchet teeth, a clicker operatively engaged between said dose set knob and said driver having at least a DSK ratchet arm and at least a driver ratchet arm, wherein said driver is prevented from rotating with said dose set knob while moving axially with said dose set knob during dose setting and dose correcting, and when said push button is depressed, said clicker pushes said driver distally such that said at least one external tooth of said driver engages said at least one internal tooth of said dose set knob thereby forcing said driver to rotate with said dose set knob during an injection.

摘要： A medical injector has a body with a displaceable plunger. The plunger includes a plurality of spaced-apart ratchet teeth disposed along the length thereof. At least one indexer is provided to engage the plunger, wherein the indexer is configured to allow the plunger to displace distally toward a distal end of the body but not proximally toward a proximal end of the body. The medical injector also includes an actuator having an engagement portion formed to engage one or more of the ratchet teeth. The actuator is displaceable to a ready state, the engagement portion being displaced proximally relative to the plunger with the actuator being displaced to the ready state. The indexer prevents proximal movement of the plunger, thereby allowing the engagement portion to bypass one or more of the ratchet teeth with the actuator being displaced to the ready state. In addition, the actuator is displaceable from the ready state to cause actuation of the medical injector. The displacement from the ready state causes distal displacement of the engagement portion with the engagement portion engaging one or more of the ratchet teeth and causing distal displacement of the plunger with the engagement portion.
摘要翻译： 医用注射器具有带有位移柱塞的主体。 柱塞包括沿其长度设置的多个间隔开的棘轮齿。 提供至少一个分度器以接合柱塞，其中分度器构造成允许柱塞朝向身体的远端远端移动，而不向近侧朝向身体的近端移位。 医疗注射器还包括具有形成为接合一个或多个棘齿的接合部的致动器。 致动器可移动到就绪状态，接合部分相对于柱塞向近侧位移，致动器被移位到就绪状态。 分度器防止柱塞的近端运动，从而允许接合部分绕过一个或多个棘轮齿，致动器被移动到就绪状态。 此外，致动器可从就绪状态移位以引起医用注射器的致动。 从就绪状态的位移导致接合部分的远端位移，其中接合部分接合一个或多个棘齿，并引起柱塞与接合部分的远端位移。

摘要： A system including an adapter for sequential engagement with a cartridge containing a first substance and a vial containing a second substance is disclosed. The adapter is configured to first engage with the vial and subsequently engage with the cartridge such that the cartridge is in fluid communication with the vial via the adapter. The system includes a latch member engageable with a portion of the cartridge. A plunger rod includes a protrusion and is adapted to communicate with the latch member, the plunger rod being transitionable from a disengaged position, in which the protrusion of the plunger rod is disengaged from the latch member and the latch member is locked to the cartridge, to an engaged position, in which the protrusion is engaged with the latch member and the latch member is unlocked from the cartridge and locked to the plunger rod.

摘要： A device for delivering a fluid includes a housing defining an interior space and having a bottom surface configured for contacting a patient. The bottom surface defines a needle opening. The device also includes a reservoir disposed within the interior space of the housing for containing a fluid therein, a needle carrier disposed within the housing, and an injection needle supported by the needle carrier and defining a lumen. The lumen of the injection needle is configured to be placed in fluid communication with the reservoir. The injection needle is transitionable from an initial position in which the injection needle is disposed within the housing, to a use position in which the injection needle extends through the needle opening, and a substantially shielded position in which the injection needle is disposed within the housing and the lumen of the needle is blocked by a portion of the housing.

摘要： A removal device (121, 221) for removing and disposing of a pen needle (113, 213) connectable to a drug delivery device (111, 211) includes a body (123, 223) having a cavity (141, 241) for receiving the pen needle of the drug delivery device such that a patient end (116, 216) of a needle (115, 215) of the pen needle is covered by the body. An ejector (151, 251) is movably connected to the body (123, 223) for engaging the received pen needle (113, 213) and selectively ejecting the engaged pen needle from the body. The pen needle (113, 213) is securely retained within the removal device (121, 221) without exposing the needle (115, 215) of the pen needle until the pen needle (113, 213) can be properly disposed of, such as in a sharps container, thereby substantially preventing an accidental needle stick.

摘要： An injection pen (1) includes a housing (2), a lead screw (75), a dose set member (6), a setback member (17), and a rotatable driver (60). The lead screw (75) is axially moveable in the housing (2). The dose set member (6) is connected to the housing (2) for dose setting and dose correcting. The setback member (17) is operatively connected to the dose set member (6). The rotatable driver (60) is operatively connected to the setback member (17) and the lead screw (75). The driver (60) is prevented from rotating during dose setting and dose correcting, and the driver (60) rotates during an injection to axially move the lead screw (75).
