The present disclosure provides medical devices, particularly medical grade needles with removable tips, as well as methods of needle tip installation and removal, and devices therefor. Needle tip installation and removal devices may include needle tip installation and removal tools and kits, including hand held and manipulated tools that facilitate the installation and removal of needle tips, particularly on vascular access port needles. Such installation and removal devices may provide more expedient hook up of the access port for the therapy. Also, the installation and removal of the needle tips may be conducted in a more sterile manner.

The present invention relates to a filtering syringe, and more particularly, to an apparatus obtained by improving a syringe provided with a filter means for filtering foreign substances such as glass fragments of an ampoule, so that opening or closing of a one-way valve means is controlled depending on whether a cap is separated, and that the filter means can be also designed to be larger in cross-sectional area so as to allow a liquid medicine to be smoothly sucked with a smaller force. The filtering syringe is configured such that the liquid medicine is filtered and sucked through the filter means having the larger cross-sectional area even with the smaller force in a cap-assembled state and the one-way valve means is automatically closed to allow the liquid medicine to be injected in a cap-separated state, thereby maximizing user's convenience and marketability of the syringe.

User-friendly attachment mechanisms for pen needles provide improved handling and ease of use, including locking installation and removal features and sensory feedback when a needle-bearing hub is seated on a pen. Embodiments include a needle-bearing hub includes a circumferentially oriented flexible tab that engages a radially inward rib on an outer cover to assist in attaching a pen device to the pen needle.

A needle tip (22) for being connected and disconnected in use from a needle tip support (16), comprises a needle (24) having a forward end and a rearward end and, a connector secured to the needle intermediate its ends. The connector comprises two arms (28) each extending outwardly and rearwardly relative to the needle (16) and configured to be coupled and uncoupled in use from said needle tip support, and the arms are disposed on opposite sides of the needle. Also disclosed are arrangements for storing, dispensing and later disposing such needle tips, as well as coupling interfaces between the needle tip and a needle support cap to which it is fitted in use.

A method for producing an injection device are disclosed. The injection device comprises a hollow needle which is positioned in a basic body of the injection device. The injection device is produced by a two-stage injection process. At least one first slider and a second slider are provided in a tool block. Together with the tool block, the first slider and the second slider form free space, which defines a shape of a pre-injection molded part of the basic body of the injection device.

A dual-needle syringe capable of preventing infection, including: an infusion needle shaft (3) configured to aspirate a liquid from a drug container (30); an injection needle shaft (5) having a sharp point of one end inserted into a body, and the other end connected to the syringe (10), through which the liquid filled in the syringe (10) is injected into a body; a hub barrel (7) engaged to a barrel (15) of the syringe (10) to infuse the liquid, which is aspirated from the drug container (30) through the infusion needle shaft (3), into the syringe (10) through the injection needle shaft (5), the hub barrel having an infusion needle shaft hub (21) and an injection needle shaft hub (23) which can be separated from each other before the liquid is injected; and a filter (9) configured to filter foreign substances contained in the liquid.

An injection device including a syringe including a barrel having a distal end and a proximal end and a tip provided on the distal end of the barrel, the barrel defining an internal bore extending from the proximal end to the distal end of the barrel; a luer lock adaptor including a body having a proximal end and a distal end, a reduced-diameter portion provided on the proximal end of the body, and a threading provided on an outer surface of the body, the reduced-diameter portion defining an opening to receive the tip of the syringe in a friction fit; and a needle hub including a body defining an inner cavity, a needle receiving portion extending distally from the body, and a skirt extending inwardly into the inner cavity.

A wearable drug delivery device includes a housing, a needle assembly at least partially disposed in the housing, and a drive assembly at least partially disposed in the housing and coupled to the needle assembly. The needle assembly includes a needle or cannula and a sterile barrier disposed proximal to the needle or cannula in a first configuration where the sterile barrier is intact. The drive assembly includes a container that contains a medicament to be administered, a first plunger disposed in the container, and a drive mechanism that forces the first plunger to urge the medicament through the container. Upon engaging the drive mechanism, the needle or cannula and the sterile barrier move relative to each other from the first configuration to a second configuration where the needle or cannula breaks the sterile barrier, thereby allowing the medicament to be administered via the needle or cannula.

A safety device for preventing needlestick injury with a needle, including a protective cap and a shield capable of pivoting from a storage position where it is interlocked with the protective cap, a retracted position where it gives access to the needle and a safety position where it covers the needle, wherein a cam surface of the shield and an engaging peg of the protective cap are arranged so that, when the safety device is mounted around the tip of a medical device, removing the protective cap from the tip by a distal movement displaces the shield from the storage position to the retracted position. A medical device including a tip provided with a needle including a needle point, wherein the medical device further includes a safety device.

The invention relates to a process for producing and assembling an aseptic container (100, 200) suitable for containing and supplying medical liquids comprising in sequence at least the steps of extruding a plastic material, operating on the intermediate tubular element obtained by blow moulding so as to obtain at least a hollow body (2, 202) and sealing the hollow body (2, 202) with a cap having a small size or applying an insert, comprising at least a portion (4, 204) with facilitated breakage.
