An injection assembly includes a syringe barrel (12) having a proximal end and a distal end, a needle hub (20) supporting the needle and coupled to the distal end of the syringe barrel (12). A sleeve (32) is positioned on the syringe barrel and needle hub for sliding between a first position where the needle is covered and a second position exposing the needle. The sleeve (32) is biased to the extended position to cover the needle. The sleeve has a distal end (38) and a proximal end (40). During use, the syringe is positioned against the skin of the patient so that distal end of the sleeve contacts the skin of the patient before the needle so that lateral or angular force applied relative to the surface of the skin is absorbed by the sleeve to inhibit sliding of the sleeve and resist bending of the needle during insertion.

In one aspect of the subject invention, a grip is provided for mounting to a syringe, the grip including: an elongated body extending along a longitudinal axis between first and second ends, the first end defining a female luer fitting configured for mounting onto the syringe, an inlet opening being defined in the female luer fitting, the second end defining a male luer fitting defining an outlet opening, and, a liquid passageway defined through the body between the inlet opening and the outlet opening to allow liquid flow therebetween. The body further defines an outer surface encircling the longitudinal axis, the outer surface being at least partially textured. Advantageously, with the subject invention, a grip is provided which is configured to both mount to a syringe and to mountingly receive a cystotome, in providing an enhanced gripping surface for a practitioner performing a capsulotomy.

The present invention is directed to a needle retention assembly, an injectate delivery system, a needle, and a safety mechanism, all of which are for use with an injection device. The needle retention assembly includes a needle offset nut which is configured to removably attach to a needle retention nut and to provide support to the needle. The injectate delivery system includes an injectate holding compartment, a plunger, and a resilient member. The needle has a sidewall defining a longitudinal channel and includes at least two orifices in the sidewall, but does not include an orifice at a tip of the needle. The safety mechanism includes a dual switch that includes two switch elements that are each positioned on opposing sides of a handle of the injection device.

Provided is a fluid wicking tip. The fluid wicking tip includes a plurality of drip flanges arranged to wick fluid between narrow spaces defined between any two drip flanges. The narrow spaces are dimensioned to facilitate wicking by capillary action. Also provided is a syringe that includes the fluid wicking tip. Also provided is a spike tip including a series of tiered drip flanges for retaining fluid spilled from a bulk fluid container during a syringe filling operation.

The purpose of the present invention is to provide an injection needle unit, provided with a plurality of needle pieces, with a simple structure and capable of easy manufacturing. The injection needle unit provided with: a needle base provided with a medicinal solution accommodation space; and a plurality of needle pieces, each of which is attached to the needle base, and a base end of the needle piece communicates to the medicinal solution accommodation space. The needle base is composed of: a needle base body, provided with an opening for opening the medicinal solution accommodation space in the direction orthogonal to the axis directions of the needle pieces; and a lid for enclosing the opening of the needle base body.

A needle assembly includes a needle, a rear needle cap and a front needle cap. The needle includes a needle hub and a needle shaft running through and attached to the needle hub. The shaft incorporates two sharp ends and an internal channel running through the entire length of the shaft. The needle hub includes a rear needle body and a front needle body. The rear needle cap is adapted to be attached to the rear needle body and the front needle cap is adapted to be attached to the front needle body. The front needle body incorporates a guiding channel and a locking receptacle connecting to and extending from the guiding channel in a needle detachment direction. The front needle cap includes an internal locking plug adapted to move along the guiding channel and be disposed inside the locking receptacle. The front needle cap also incorporates a funnel lip.

The device includes a housing, said housing defining an internal conduit for circulation of the medical fluid from a fluid inlet to a fluid outlet,

a slider arranged inside the internal conduit such that the slider is movable along a central longitudinal axis A between an opening position, wherein the medical fluid is allowed to flow through the fluid outlet, and a closing position, wherein the medical fluid is prevented from flowing through said fluid outlet,

a plug connected to the slider said plug being configured to close the fluid outlet when the slider is in the closing position,

a resilient member disposed proximally to the plug and configured to exert a proximal force on said the slider such that the resilient member maintains the slider in the opening position,

a proximally oriented pressure area provided on an actuation member of the slider, said pressure area being configured to cause the slider to reach the closing position against the action of the resilient member when the medical fluid pressure exerted upon said pressure area is equal to or higher than a predetermined threshold, thereby causing the plug to close the fluid outlet.

Improved systems and methods for medicine delivery, and in particular, improved insulin pen needles and related devices are provided. Smart injection devices record and transfer data including medicine level, delivered dose, dose confirmation, and dose time and date. Additional data captured may include glucose concentration, insulin level, carbohydrates ingested, stress level, exercise, blood pressure, and glucose high and low excursion events. Various means of data collection and analysis are provided and systems can identify and flag patients who require intervention. Smart sleeves and add sensing capability to standard insulin pens. Pen needles are provided with sensing capability to confirm and measure doses delivered by insulin pen. A two-part pen cap include a primary sleeve that connects to the insulin pen and an end cap that provides for capturing the time of dose delivery, and monitoring the hold time for a dose delivery after plunger movement.

A drug delivery device for administering a drug is presented having a body adapted to retain a cartridge containing a drug, at least one electrical unit and a port for electrically contacting the electrical unit, an adapter for attaching an injection needle to the drug delivery device, a safety mechanism arranged to prevent contacting the electrical unit through the port whilst an injection needle is in fluid communication with the cartridge and arranged to prevent establishing a fluid communication between an injection needle and the cartridge whilst the port is configured to allow contacting the electrical unit.

A hard-packaged safety needle device comprises a needle hub comprising a distal portion and a proximal portion, a needle cannula extending from the distal portion of the needle hub, and a hard needle enclosure comprising a needle cover, an adapter and a cap. The needle cover is configured to house the needle cannula, and the adapter has a tapered aperture configured to create an interference fit and a sterility barrier with the tapered outer surface of the needle cover. The caps includes a distal opening defining a first cavity, the cap being configured to interdigitate with the adapter by the first cavity of the cap receiving a proximal portion of the adapter.
