摘要： A gear-driven infusion assembly is provided which has a housing, a gear assembly coupled to the housing, a shuttle assembly slidably coupled to the housing and operably coupled to the gear assembly, and a tube enclosure connected to the housing. The tube enclosure is configured to house a primary drug closure. The gear assembly includes a spool assembly having a pinion gear and a drive spool. When the spring rotates the drive spool, the drive spool drives the pinion gear, and the gear assembly drives the shuttle assembly. When the gear assembly drives the shuttle assembly, the shuttle assembly slides longitudinally along the housing. The gear assembly may be spring driven such that a spring rotates the pinion gear about the drive spool. The primary drug closure may be a syringe. An overspeed protection device is also provided which has a spool assembly including a drive spool having a plurality of cams, a spring, and a pinion gear with spiral cam surfaces.

摘要： Provided is a precision variable flow rate infusion system and method for delivering a liquid from a reservoir having an initial potential outflow rate to a patient. The system includes at least a first flexible flow rate tubing having a pre-defined flow rate selected at a maximum dosage flow rate for the liquid from the reservoir, the pre-defined flow rate being less than the initial potential outflow rate of the reservoir. Also provided is an adjustable flow rate controller having an inlet and an outlet, at least one internal fluid pathway there between and a fluid pathway modifier structured and arranged to modify the internal fluid pathway from the inlet to the outlet from a closed pathway to a maximum flow pathway with a plurality of different flow rate pathways there between. Moreover, the at least first flexible flow rate tubing and adjustable flow rate controller determine the maximum flow rate of liquid from the reservoir to a patient and the adjustable flow rate controller permits precision flow rate control from an off flow rate to about the maximum flow rate permitted. Associated methods of providing, calibrating and using the precision variable flow rate infusion system are also provided.

摘要： The present disclosure relates to a connector for connecting flow channels, flow regulators and/or reservoirs for directing flow. In some embodiments, the connector is a medical connector for connecting fluid flow controlling elements used in medical applications, particularly in infusion systems, such as tubes, syringes, needles, catheters and fluid reservoirs. The connector reduces the risk of contamination during handling and enhances safety when administering therapeutic solutions into a patient.

摘要： The present invention generally provides a device for inserting needles and alleviating the discomfort associated with needle insertion. In certain embodiments, the device is suited for injecting butterfly needles and particularly butterfly needles that are attached to infusion tubing. The patient or caregiver loads a butterfly needle with tubing attached into the base of the drive plunger. The needle with tubing attached is retracted into the housing of the device by retracting the inner plunger. Once retracted, the device is activated and ready to administer a needle into the tissue of a patient. The device is then placed on the location of the skin where injection is desired. The surface that contacts the skin may be textured and may include a contact switch that causes the device to vibrate when slight pressure is applied through contact with the skin. Two trigger buttons in the housing of the device may be depressed to eject the needle at an angle essentially perpendicular to the surface of the skin into the tissue of the patient concurrently with the textured pads contacting the skin and vibrating, distracting the patient from the needle insertion. The inner plunger of the device is then depressed toward the surface of the skin to release the needle from the device. The wings and body of the butterfly may be secured to the skin, for example, with an adhesive such as tape.

摘要： Provided is a system and method for an anti-foaming needle assembly for avoiding foam generation when extracting a liquid from a vessel having a chamber with a bottom and opposite thereto an opening sealed with a penetrable and re-sealable stopper providing an inner surface above the chamber. More specifically, the anti-foaming needle assembly includes a needle base having: a first end and opposite thereto a second end and a sidewall there between, the second end structured and arranged for temporary connection to a syringe having a barrel and a plunger; a first needle having a hollow shaft and a first length extending from the first end to provide an open distal end above the first end, the first needle having a second end vented through the sidewall; and a second needle having a hollow shaft and a second length extending from the first end generally parallel to the first needle to provide, when inverted, a distal end above the first end and below the distal end of the first needle, the second needle having a second end in fluid communication with the second end of the needle base. An associated method of use is also provided.

摘要： Provided is a system and method for a removable syringe micro pump. More specifically, the removable syringe micro pump includes a pump housing having a first end and opposite thereto an attaching end, and at least one sidewall there between, the housing having a base proximate to the first end and, the attaching end having an attacher structured and arranged to temporarily engage a syringe. A volute spring is nested within the housing and attached proximate to the base, the volute spring having a compressed first position wherein coils of the volute spring are concentrically disposed under tension such that an initial height of the volute spring is equivalent to a width of a coil, and an extended second position wherein the release of tension extends the volute spring normally away from the pump housing. The volute spring has a diameter pre-selected to pass within a barrel of the engaged syringe. The volute spring further having a distal end structured and arranged to engage a plunger seal of the engaged syringe, wherein the release of tension between the first position and the second position permits the distal end of the volute spring to move the plunger seal towards a nozzle of the syringe. An associated method of use is also provided.
