  • Patent number: 10307337
    Abstract: An improved oral administration coupler for delivery of fluids such as medications and nutritional fluids. Example oral administration couplers have a first end with an applicator for oral delivery to an infant, and a second end with a coupling compatible with an enteral fluid delivery syringe. A fluid delivery conduit extends in fluid communication from the first end to the second end, to deliver fluid from the syringe to the infant. In some example embodiments, the coupler is configured for back-of-mouth delivery, and can comprise a generally elongate and at least partially flexible tube or straw.

  • Patent number: 9408975
    Abstract: An apparatus for operating a syringe has developed comprising: an upper semi-cylindrical tube section, semi-circular shaped locking groove and lower semi-cylindrical tube section. The upper semi-cylindrical tube section is integrally formed an upper head part with a threaded hole for axial movement. The lower semi-cylindrical tube section forms a top portion, intermediate portion and end portion. A diameter (Dc) at the intermediate portion larger than the diameter (Dtip) at end portion is gradually reduced from intermediate to end portion. The length of the tapered portion is same as that portion of the constant diameter. A tip portion has formed an opened semi-circular shape to simply overlap the syringe over the cartridge for easily snapping-in and out. The syringe piston moves downward with no reverse action when the piston press-unit is rotated, thus it is possible to inject the precise amount of medicine to a patient with constant pressure.

  • Patent number: 9378445
    Abstract: This inventive method assures the authenticity of drugs or other valuable substances that reside within product containers, such as syringes. The method includes initially measuring the 3D topology of the glass surface while determining the distance to the glass surface. Thereafter, a desired 3D code is written below the glass surface with a pulsed laser system. The written 3D code is readable using optical coherence topography (OCT) or parallel optical coherence tomography (pOCT) to verify the authenticity of the product container. A system uses this method with a plurality of syringes held within a tray, and a writing apparatus that moves relative to the tray to write a predetermined 3D code on each of the syringes held in the tray, during processing of the syringes along a process line while in the tray.

  • Patent number: 8491539
    Abstract: An aspiration apparatus includes handles with two members. Each of the handle members includes a proximal actuation end and an opposite distal connection end. The members of the handles are associated with one another (e.g., pivotally, etc.) in such a way that movement of the proximal actuation ends in first directions (e.g., toward one another, away from one another) causes the distal connection ends to move in opposite second directions (e.g., away from one another, toward one another). The distal connection end of the first member may configured for association with the barrel of a syringe, while the distal connection end of the second member may be configured for association with the plunger of the syringe. Association of one or both of the distal connection ends with its respective syringe element may be pivotal. Aspiration methods, including, but not limited to, methods of using such an aspiration apparatus, are also disclosed.

  • Publication number: 20130085455
    Abstract: A syringe assembly includes a syringe barrel having a first end, a second end, and a sidewall extending between the first end and the second end. The syringe assembly further includes a stopper disposed within a chamber of the syringe barrel, a plunger adapter engaged with the stopper, and a plunger rod having first and second ends. The first end of the plunger rod is pivotally secured to the plunger adapter. The plunger rod has a pre-use position where the second end of the plunger rod is positioned adjacent to the syringe barrel, and a use position where the plunger rod is configured to displace the stopper relative to the syringe barrel. A recessed portion of the plunger adapter receives a portion of the first end of the plunger rod when the plunger rod is in the pre-use position and the use position.

  • Patent number: 8308726
    Abstract: A system to minimize fluid turbulence inside a tissue cavity during endoscopic procedures. A body tissue cavity of a subject is distended by continuous flow irrigation using a solenoid operated pump on the inflow side and a positive displacement pump, such as a peristaltic pump, on the outflow side, such that the amplitude of the pressure pulsations created by the outflow positive displacement pump inside the said tissue cavity is substantially dampened to almost negligible levels. The present invention also provides a method for accurately determining the rate of fluid loss into the subject's body system during any endoscopic procedure without utilizing any deficit weight or fluid volume calculation, the same being accomplished by using two fluid flow rate sensors. The present invention also provides a system of creating and maintaining any desired pressure in a body tissue cavity for any desired cavity outflow rate.
