An injection pen, or an adapter for an injector pen, configured to connect at its distal end with a needle assembly, and having a tubular wall comprising a through cut from the distal end to pierce and capture barrier material covering needle assembly packaging containing a needle assembly in a cavity therein. The though cut has an opening with an edge that scythes the barrier material when the hub is pressed against the needle assembly packaging to access the needle assembly. The edge can have a tooth for piercing the barrier material. The opening can be dimensioned and shaped and angled relative to the longitudinal axis of the pen or adapter to facilitate capturing scythed barrier material and guiding it away from the needle assembly to ensure the pierced barrier material does not hinder connection of the needle assembly to the pen or adapter.

A connection structure of a medical container includes a liquid medicine containing part that contains a liquid medicine and a liquid medicine discharge part that discharges the liquid medicine includes: a sealing member including a mounting part to be mounted to cover the outside of the liquid medicine discharge part, an opening formed in the mounting part in an extending direction of the liquid medicine discharge part, and an elastic sealing body disposed in a space between the opening and the liquid medicine discharge part and sealing the liquid medicine discharge part; and a connector including a connection needle that punctures the elastic sealing body, and a needle hub that holds the connection needle, in which the connector has a push-in structure that compresses the elastic sealing body when the connection needle punctures the elastic sealing body.

A medicine injection catheter includes: a catheter main body formed with a medicine supply lumen; a tubular body connected to the distal end of the catheter main body and having a lumen communicating with the medicine supply lumen; an injection needle connected to the tubular body; a tubular cover member that accommodates the tubular body and that is configured to be advanced and retracted in the axial direction of the catheter main body between a first position where a distal end of the injection needle is accommodated in the tubular cover and a second position where the distal end of the injection needle protrudes forward from the inside space; a closing member to close and open the lumen of the tubular body, a motion conversion mechanism which converts advancing/retracting motion of the cover member into movement of the closing member to close the lumen of the tubular body.

An improved device delivers a fluid medicament to the subcutaneous tissue of a user. The device is better suited for patients with Parkinson's Disease and other central nervous system disorders, than conventional infusion devices. The device can include a reusable part including a drive component (e.g., motor) and control electronics and a disposable part including a medicament reservoir. Medicament can be evacuated from the medicament reservoir by a plunger assembly that includes a plunger attached to a lead screw that is rotated by a nut, all within the disposable part. The device can be fluidically coupled with the tissue via a flexible cannula. Various embodiments relate to an improved cannula insertion mechanism that delivers the cannula under a force applied by a spring. Various embodiments relate to improved filling of the device, for example, using a vial adapter and an automated filling station.

An adapter for attaching a needle to a pump actuated vial for injection of a vaccine or drug using a syringe-type injection motion while eliminating the time-consuming preparation of the injection device. The adapter includes a spray pump device having a first end defining a luer tip and a second end configured for accessing a media reservoir to receive a metered dose of flowable media. The luer tip is configured to be secured to a needle cannula to deliver the metered dose of the flowable media received from the spray pump device.

Improved apparatus for use with medication in fluid form, which is particularly beneficial for medications having a relatively high viscosity. The disclosed syringe adapter has an opening that is relatively large, as compared to a conventional needle, and thus affixing the disclosed syringe adapter to a syringe improves syringeability of higher-viscosity medications. Some embodiments feature a lateral extension that prevents inserting the syringe adapter too far into a medicine bottle, and some embodiments feature a component that assists in firmly grasping. When the disclosed syringe adapter is affixed to a pistol-grip or tab-handled syringe, the medication withdrawn into the pistol-grip syringe can be more easily administered from the syringe barrel. In some embodiments, the syringe adapter will be replaced with a needle prior to injecting the medication, while in some other embodiments, the needle is affixed to the in-place syringe adapter for the injection. In yet other embodiments, the needle is affixed to a needle holder that, in turn, is affixed to the in-place syringe adapter for the injection.

A medicament delivery device is disclosed, comprising a cartridge assembly that comprises a cartridge having a medicament chamber for containing a medicament, a sealing element for sealing a distal end of the medicament chamber and a coupling element attached to the cartridge. The device also includes a sealing element release member, a cannula for delivery of the medicament, and a removable cap. The device is switchable from a starting configuration in which the release member is spaced from the sealing element to an activated configuration in which the release member cooperates with the sealing element to connect the medicament chamber to the cannula. A proximal end of the release member is sealed in a release member chamber defined in part by, the sealing element and in part by the coupling element.

A collar for reinforcing a barrel outlet spout of an applicator, syringe or the like, the barrel having a substantially cylindrical main body, with the outlet spout at one end thereof, wherein the collar includes: a spout engagement portion; and a main body engagement portion.

A quick-connect syringe and needle system is provided including a syringe having a threaded portion, a needle assembly having a needle body and a needle affixed to the needle body and an intermediate adapter engageable with the syringe and releasably engageable with the needle body. A quick-connect mechanism is provided on the needle body and intermediate adapter for quickly and easily connecting the needle assembly with the syringe and intermediate adapter. The quick-connect mechanism can include a pair of diametrically opposed L-shaped slots formed in a rear portion of the needle body and a pair of corresponding and diametrically opposed projections extending from a front or locking portion of the intermediate adapter. The needle assembly is attached to the intermediate adapter by inserting the projections into the slots and giving the assembly a quick quarter turn to firmly seat the projections within the slots.

The present invention relates to a device for measuring, recording, and acting in response to changes in air pressures encountered through the lumen of a connected needle. The device signals when it has been powered and signals when the device recognizes both pressures and pressure change rates indicative of synovial cavity joint penetration, such as knee joint penetration. Synovial cavity pressures detected and acted upon may either be supra- (positive) or sub-atmospheric (negative). Internal light emitting diodes and a laptop connected display are demonstrated as signaling and communication mechanisms. Methods for delivering medicaments into human and animal intra-articular cavities or joints such as synovial cavities are provided. Furthermore, methods for facilitating the diagnoses of joint effusion also are provided.
