Автор: Kurt SHIMER, Matthew GUNN, Raymond Bizup
Принадлежит: Medical Components Inc

Disclosed is a Huber needle assembly that may include an upper body connected to a lower body, the assembly being structured to retain a needle for insertion/extraction of the needle into/from an insertion site. The upper body can statically retain the needle while the lower body may slidably receive the needle. The lower body can further include a catch that engages a tip of the needle and/or misaligns the tip of the needle with a needle aperture of the lower body to place the assembly in a safety-lock position, preventing rebound, needle-stick injury, and/or any type of exposure of the needle tip to an environment outside of the lower body. The assembly can further bias the needle in a direction so as to prevent re-emergence of the needle tip after being withdrawn into the lower body.

PAINLESS DRUG IMPLANTER

Принадлежит:

The present invention relates to a drug implant device which delivers a drug load to the body painlessly. The present invention achieves the painless drug implantation by adopting two principles: (1) rapid perpendicular insertion of fine cannula is painless and that (2) pain is incurred only when the occupied volume caused by the implant process is increased. Therefore, instead of inserting a cannula and injection a volume of drug, which increases the occupied volume of the injection process due to additional volume of the drug, the present invention retracts the cannula in order to dispose the drug into the body. The retraction of cannula does not increase the occupied volume therefore incurs no pain. In the preferred embodiment, the drug implant device () comprises a cannula () with a bevelled tip, a drug load () and an inner rod (), wherein the drug load () and the inner rod () are slidably disposed within the cannula (), and that the drug load () is disposed at the bevelled end of the cannula () and that the inner rod () is disposed adjacent to the drug load (). 1.

A retractable syringe is proposed having a cutting head mounted on a plunger of the syringe. When the plunger is advanced to expel fluid from the syringe, the cutting crown cuts a retention mechanism which holds a needle unit of the syringe, allowing a drive mechanism to drive the needle unit into the syringe. The cutting crown is shaped to reduce the force which has to be applied to cut the retention mechanism. Furthermore, a disposable needle assembly for attachment to a syringe unit is proposed. The disposable needle assembly has a needle and connector element for connecting the needle to the syringe unit. The connector element encircles the needle and has a thread on its outer surface for mating with the syringe unit. 1. A retractable syringe comprising:a barrel;a needle unit comprising a needle, an interior of the needle being in fluid communication with a chamber within the barrel;a retention mechanism for retaining the needle unit at one end of the barrel;a hollow plunger movable within the barrel towards the needle unit;a drive mechanism for driving the needle unit into the plunger; anda cutting crown at the end of the plunger facing the needle unit, the cutting crown being arranged for cutting the retention mechanism as the plunger is advanced, so that the drive mechanism retracts the needle unit into the barrel;wherein a piston is disposed over the cutting crown, and the piston has a weakened portion which is arranged to be cut by the cutting crown before the cutting crown cuts the retention mechanism; and wherein the weakened portion comprises a plurality of notches.2.

A syringe fill system is described, which is useful for filling syringes for dental anesthetic applications. The system incorporates capability for “push-pull”, “pull-push”, “push-push”, and “pull-pull” modes of operation, for loading syringes with compositions comprising multiple fluid components. A syringe fillable by such syringe fill systems is described, providing haptic and audible feedback to a user, to aid in administering precise amounts of therapeutic compositions. Also disclosed are cassette assemblies for use in such syringe fill systems. Such cassette assemblies may be formed of plastic and elastomeric materials of construction, as disposable or single-use components of the syringe fill system.

An enteral dosing control coupling comprising a cylindrical collar defining a hollow internal chamber and a lumen extension tip projecting axially into the internal chamber, the lumen extension tip defining an internal lumen extending therethrough. In example forms, the lumen extension tip is integrally formed with the cylindrical collar. In other example forms, the lumen extension tip is a separate piece and is removably engageable within the cylindrical collar. In some example forms, the present invention relates to syringes, connectors, couplings, etc. having ISO 80369-3 formatted couplings. In other example forms, the present invention relates to connectors, couplings, etc. for adapting coupling formats other than the ISO 80369-3 coupling format to the ISO 80369-3 coupling format.

A cold slurry syringe with enhanced features is provided for delivering a cold slurry into the human body. The syringe includes a syringe body for holding a volume of cold slurry, a plunger that slides within the syringe body for ejecting the cold slurry, and a tapered syringe head for delivering an even flow of cold slurry. An agitator can be added to keep the cold slurry from agglomerating and clogging the syringe. Insulation added around the syringe can keep the cold slurry from melting too quickly. A ball screw drive can be added to provide a smooth and consistent application of pressure as the cold slurry is delivered. The cold slurry flow can be enhanced by adding a streamline flow feature that reduces the occurrence of eddies or swirls inside the syringe. This feature can also help maintain the composition and consistency of the cold slurry. 1. A device for delivering cold slurry , the device comprising: a first end and a second end;', 'a longitudinal axis extending from the first and second ends;', 'an interior lumen defined by an interior wall of the syringe body, the interior lumen configured to receive and contain a volume of cold slurry;, 'a syringe body comprisinga plunger slideably movable within the interior lumen along the longitudinal axis, the plunger comprising a stopper and a stem extending from the stopper; and an inlet defining a first passageway in fluid communication with the interior lumen of the syringe body, the first passageway having a first diameter about the same as a diameter of the interior lumen;', 'an outlet spaced a predetermined distance from the inlet along the longitudinal axis, the outlet defining a second passageway in fluid communication with outside to serve as an exit for delivering cold slurry, the second passageway having a second diameter smaller than the first diameter; and', 'a reducer extending between the inlet and outlet, the reducer defining a third passageway in fluid communication with the first and second ...
