A needle puncture device comprises: a needle base; a needle; a first structural member disposed outside of the needle base, slidably engaged with the needle base in an extending direction of the needle, and provided with a first restriction mechanism configured to restrict the first structural member from separating from the needle base along the extending direction of the needle; and a second structural member disposed outside of the first structural member, slidably engaged with the first structural member along the extending direction of the needle, and provided with a second restriction mechanism configured to restrict the second structural member from separating from the first structural member along the extending direction of the needle. The present invention has the advantages of both operational convenience for an operator and skin comfort for a patient, and the structural members above the needle base can quickly cover the needle after use.

The injection needle removal device has: a cylindrical outer cylinder on an upper opening of an injection needle case; a helical track on an inner peripheral surface of the outer cylinder in a helical shape from an upper locking point to a lower locking point; a syringe holding cylinder helically advances in the outer cylinder along the helical track; an injection needle tightening ring on a lower end portion of the syringe holding cylinder, the injection needle tightening ring holds an injection needle base portion of a syringe in the syringe holding cylinder to clamp the injection needle base portion; and a locking mechanism that stops the syringe holding cylinder where the injection needle tightening ring is exposed from a lower side of the outer cylinder at the lower locking point. The injection needle tightening ring turns to remove the syringe needle base portion from the syringe body and to expand in a distal-end divided manner by a turning generated by a descending movement of the syringe holding cylinder proximate the lower locking point to discard the injection needle base portion into the injection needle accommodation case with the injection needle.

The invention may include a knife having a syringe hub remover. In one embodiment, the invention may include a hub slot that may be integral to the knife tang and that may further be configured to be positioned over a syringe hub and allow for an improved leveraged torque force to be applied thereby twisting and ultimately assisting in the removal of the syringe hub.

The present disclosure relates to a device for handling medicament delivery devices and is to be used with a safety container, where the medicament delivery devices have information retaining elements having information that is unique to specific medicament delivery devices, and which medicament delivery devices are to be put in a safety container after use. The disclosed device has an information obtaining mechanism operably arranged to obtain information from the medicament delivery devices placed into the safety container.

An apparatus and method are provided for opening auto-injectors for subsequent servicing and refilling with medicament. The apparatus opens and disassembles an auto- injector to gain access to its drug reservoir so that a replacement medicament may be applied. The apparatus provides for reassembling the auto-injector as a medical device for subsequent service.

An attachable needle assembly (2) used on a medication delivery pen (4), the needle assembly (2) comprising a communication needle (10) configured to pierce a reservoir septum of the medication delivery pen (4), a spike housing (8) surrounding the communication needle (10) and configured to engage the medication delivery pen (4), a selector ring (16), including a selector opening (18), enclosing a septum (22, 30) of the needle assembly (2) defining a septum chamber (28, 29) that is in fluid communication with the communication needle (10), a plurality of needles (34) disposed in the septum (22, 30) of the needle assembly (2), and a peel tab (60) enclosing each of the plurality of needles (34), wherein the selector opening (18) is aligned with a selected peel tab (60) corresponding to a selected needle (40), the selected peel tab (60) is drawn out of the selector ring (16) and moves the selected needle (40) from a first position to a second position, and the selected needle (40) enters into fluid communication with the communication needle (10) in the second position.

A waste receiver for receiving pharmaceutical waste material and adapted to be releasably secured to a fixed surface is disclosed. The waste receiver comprises a receiver body with a fluid absorber and a chemical composition disposed within the receiver body. The receiver body defines an opening for receiving the pharmaceutical waste material and comprises an inner surface defining a container volume in fluid communication with the opening, and an outer surface opposite the inner surface with the outer surface defining a lock passageway through the receiver body and a keyway comprising a portion of the lock passageway. The lock passageway is adapted to receive a locking assembly and the keyway is adapted to receive an engagement feature of the locking assembly to releasably secure the waste receiver to the locking assembly in a single orientation. The waste receiver also comprises a cover adapted to be coupled with the receiver body.

A cap remover for removing a cap covering a needle of a medical injector includes a body having an insertion portion at its proximal end configured to at least partially accommodate the cap, and a grabbing portion at its distal end having an internal cavity which includes an extraction member having a series of laminas extending radially and inwardly from a ring.

A safety needle assembly having a first hub attached to a flexible tube and a second hub attached to a needle projecting through the flexible tube. A needle guard is positioned in an interior cavity of the first hub. The needle guard has a proximal wall having an opening and two arms each with an end and wherein the two ends spaced from and biased toward the needle in a ready position. In a particular example, a support is located inside the cavity of the first hub and wherein the two ends of the two arms on the needle guard rest on the support in the ready position.

A casing is described for shielding a hypodermic needle. The casing has a protective rigid housing comprised of a first open end, rigid side walls and a second closed end distal from the first open end. The first open end of the housing includes a first cylindrical inner cavity, configured to receive a first end of a hypodermic needle supported by a needle mounting assembly. The second closed end of the housing includes a cylindrical end portion, the cylindrical end portion having a second cylindrical inner cavity with a diameter smaller than the diameter of the first cylindrical inner cavity, the second cylindrical inner cavity is configured to receive a second injection sharp end of a hypodermic needle, distal to a needle mounting assembly when the needle mounting assembly is received in the first cylindrical cavity. An outer wall of the cylindrical end portion further comprises a fixing mechanism for engagement with a clamping mechanism within a container. The fixing mechanism comprises at least one slot in an outer wall of the cylindrical end portion, extending in a direction perpendicular to the longitudinal axis of the first and second cylindrical end portions, the slot being configured for engagement with a clamping mechanism.
