NEEDLE SHIELD PULLER CAP ASSEMBLY

A puller assembly for removing a shield from around a needle of a syringe. The puller assembly includes a grip component and a cap. The grip component has a tubular body defining an interior hollow which axially receives the shield. The tubular body has a slit that allows it to be forcibly shifted from a first arrangement to a second arrangement to change the size of the interior hollow. The tubular body includes a radial inner face with at least one radial inward projection for directly engaging the shield. The cap is grippable by a user. The grip component is held by the cap when inserted within a cavity of the cap during manufacturing installation, and when so held at least one radial inward projection of the grip component engages the shield for removal of the shield from around the needle when the cap is moved. A method of mounting a puller assembly to a shield around a needle is also disclosed.

Sharps end capture device and method

A sharps end capture device is disclosed for use in a system and method for the safe disposal and/or temporary storage of sharp-tipped implements including medical sharps, such as, syringe needles (epidural, spinal, blood collection, catheter, dialysis, intravenous, ophthalmic, hormonal pen, and radiologic). The device is useful to prevent injuries related to the use and disposal of sharp medical instruments, commonly known as, “sharps” or “sharps objects” is disclosed.

Medical injector with coupled body portions

A medical injector is provided herein which includes first and second body portions each having a longitudinal axis and configured to couple at a coupling. The medical injector also includes an axially-displaceable plunger; biasing element for advancing the plunger a predetermined distance; and, a releasable retainer for releasably retaining the plunger in a first state against the force of the biasing element. In an initial state, the axes of the first and second body portions are not aligned and the plunger is in the first state. In a coupled state, the axes of the first and second body portions are axially aligned, and the releasable retainer releases the plunger, thereby allowing the biasing element to advance the plunger the predetermined distance. Advantageously, the subject invention provides a medical injector having an automated plunger drive which is triggered upon assembly of the pen injector, thereby minimizing premature or failed activations.

Protection device for a needle

A protection device for a needle comprising an inner casing defining a cavity and an outer casing surrounding the inner casing, wherein the outer casing is provided with stabilizing means capable of cooperating with a substantially horizontal surface of a support so as to maintain the inner casing in a substantially vertical direction, in which an access to the cavity is left free. An assembly comprising such a protection device and a needle fixed on the needle tip of a drug delivery device.

Expandable and automatically retractable collar and method of use thereof

A flexible collar including a rigid body having a cylindrical outer surface and a cylindrical inner surface concentrically aligned with respect to a common longitudinal axis, a top surface, and a bottom surface, the inner surface defining a bore from the top surface to the bottom surface, and each of the top and bottom surfaces having an endless pathway confined to a respective plane and circumscribing a respective edge of the inner surface. The flexible collar further includes at least one accordion region having a plurality of pivots, at least two of the pivots being radially spaced apart from the longitudinal axis at different distances, and the accordion region being configured to radially deform.

Injection needle assembly

The present disclosure relates to an injection needle assembly for use in a medicament delivery device. The injection needle assembly comprises an injection needle holder, an injection needle fixed to said injection needle holder, the injection needle having a proximal end and a distal end, and a sealing assembly for sealing the distal end of the injection needle. The sealing assembly comprises a spacer element surrounding the distal end of the injection needle and a sealing membrane for sealing the distal end of the injection needle.

Dual Chamber Syringe With Retractable Needle

Embodiments of a retractable syringe assembly are provided that include a dual syringe barrel configuration. One or more embodiments include reuse prevention features and features that prevent premature activation of the retraction mechanism. Methods for aspirating and expelling liquid from medical devices are also provided.

Infusion device with releasable fluid connector

An infusion set system, including a base and a fluid connector removably coupleable thereto is disclosed. The fluid connector includes a fluid path portion and at least one connector latch displaceably connected to the fluid path portion and displaceable to a latching position in which at least a portion of the connector latch extends into the fluid path portion, which includes a cannula extending from a top interior surface thereof, and a plurality of internal sidewalls corresponding to at least two of a plurality of flat side surfaces of at least one of a base section and a base latch, thereby facilitating connection between the base and the fluid connector in a plurality of discrete rotational connecting positions. When the fluid connector is locked to the base, the at least one connector latch engages a base latching portion of the base and restricts proximal displacement of the fluid connector.

Multi-chamber injection device
11253648 · 2022-02-22 · ·

A multi-chamber injection device includes multiple syringes. The multiple syringes may be arrayed in a circular, linear, or other format. In some implementations, a needle, port, or similar may be shared by all the syringes in configuration that allows only one syringe to deliver contents at a time while blocking the other syringes from delivering their respective contents. In some implementations, the syringes may be all stored in the same container. One or more of the chambers of a multi-chamber injection device may be preloaded with medication. Different medications may be loaded into different chambers. The medications may be selected to treat the same medical condition.

Pen needle dispensing apparatus
09775944 · 2017-10-03 · ·

An apparatus is disclosed for storing and dispensing a pen needle for an injection device, including a packaging assembly including a pliable outer cover, the outer cover having a hub portion, a needle portion disposed at a distal end of the hub portion, and a flange disposed at a proximal end of the hub portion, the hub portion having internally protruding splines or other structures for engaging a hub of a pen needle. The hub portion is sufficiently pliable for a user to press gripping portions of the hub portion so that corresponding internal portions of the hub portion between the splines contacts the pen needle hub to increase a surface area contact between the outer cover and a pen needle therein.
