| 20080221531 | FLUSH SYRINGE HAVING COMPRESSIBLE PLUNGER - An I.V. flush syringe assembly includes a barrel having an inside surface defining a chamber for retaining fluid, an open proximal end and a distal end with a passageway therethrough in fluid communication with the chamber. An elongate plunger having a proximal end, a distal end and a stopper is slidably positioned in fluid-tight engagement with the inside surface of the barrel for drawing fluid into and out of the chamber by movement of the stopper relative to the barrel. The plunger includes anti-reflux structure for minimizing stopper deflection when fluid has been delivered from the chamber and the stopper is being forced against the distal end of the chamber. | 09-11-2008 |
| 20090118680 | Automatic gas filling consumable - An improved consumable for use in a fluid/gas exchange in vitreoretinal surgery. The consumable includes a syringe having a barrel with a first opening for receiving a retinal tamponading gas, a stopper slidably disposed within and fluidly sealed to the barrel, a plug assembly, and a plunger. The stopper has a relief valve for venting air and retinal tamponading gas to atmosphere via a hollow bore in the plunger. | 05-07-2009 |
| 20100324502 | SYRINGE WITH INTEGRATED VALVE MALE LUER LOCK CONNECTOR | 12-23-2010 |
| 20120059334 | SYRINGE ADAPTER WITH A BALL-TYPED VALVE - A syringe adapter with a ball-typed valve has a base, a dosing tube mounted around the base and a resilient valve mounted in the base and the dosing tube. The base has a guiding groove and an inner liquid channel communicating with each other, as well as an exhaust channel. Liquid medicine injected into the syringe adapter flows through the guiding groove and causes the inner liquid channel to be injected into a patient's body. The liquid medicine remaining in the split is cleaned when cleaning fluid is injected to clean the syringe adapter. Air in the syringe adapter flows out through the exhaust channel and is not injected into the patient's body, so the patient is free from pain. Furthermore, elements and assembling processes of the syringe adapter are simplified and manufacturing cost of the syringe adapter is lowered. | 03-08-2012 |
| 20120271244 | MEDICAL MALE LUER CONNECTOR WITH INCREASED CLOSING VOLUME - Disclosed herein is a valve assembly comprising a male luer end portion and a female luer end portion and a passage for the transfer of fluids extending between the male and female luer end portions, valve means movable between a first position, in which the passage is closed, and a second position, in which the passage is open, biasing means for biasing the valve means toward the first position, and actuating means extending into the male luer end portion and coupled to the valve means to actuate the valve means when a female luer end portion of a medical accessory is engaged with the male luer end portion. | 10-25-2012 |
| 20120271245 | MALLEABLE STOPPER FOR A SYRINGE - A syringe stopper for use in a syringe having a substantially cylindrical syringe barrel and a piston-like plunger rod for sliding inside the syringe barrel in a fluid-tight engagement. A malleable stopper is located on a distal end of the plunger rod and protrudes outwardly therefrom. The malleable stopper changes shape in response to a pressure applied thereon. | 10-25-2012 |
| 20120283662 | Method for Assembling a Drug Delivery Device, Assembly for a Drug Delivery Device and Piston Rod for a Drug Delivery Device - A method for assembling a drug delivery device comprising a body ( | 11-08-2012 |
| 20130030384 | AUTOMATIC INJECTION SYRINGE ASSEMBLY WITH INTEGRATED, FILLABLE MEDICINE CONTAINER AND METHOD OF FILLING AN INJECTION SYRINGE ASSEMBLY - An automatic injection syringe assembly having an integrated and tillable medicine container that includes a medicine container within a housing and a conduit assembly. The medicine container includes a piston having an aperture at a distal end thereof for the passage of fluid therethrough. The conduit assembly includes a conduit member that is releasably connected to the housing and has an open proximal end and an open distal end. The open distal end of the conduit member is releasably engaged with the piston and in fluid communication with the piston aperture. The open proximal end and the open distal end of the conduit member are in fluid communication via a conduit within the conduit member. | 01-31-2013 |
| 20130060204 | Syringe with prevention of backflow of blood - A syringe includes a hollow barrel and a liquid pushing assembly. The barrel has an injection end. The liquid pushing assembly includes a plunger and an elastic jacket. The plunger includes a stopper on a front end thereof. The stopper includes an abutment face. The plunger is received in the barrel. The abutment face of the stopper faces the injection end of the barrel. The elastic jacket includes a through-hole extending along an axis. The elastic jacket is mounted around the plunger. The abutment face of the stopper is exposed outside of the through-hole of the elastic jacket. | 03-07-2013 |
| 20140100532 | Syringe Devices, Components of Syringe Devices, and Methods of Forming Components and Syringe Devices - A syringe device includes a syringe barrel and piston having a fluid passageway extending from a vial port. Another syringe device includes a syringe barrel, a piston sleeve and an insert. A channel extends along a side of the insert. A valve controls fluid communication between the channel and the syringe barrel. Another syringe device has a syringe barrel, a piston sleeve and an insert. A valve controls fluid communication between a compartment within the insert and the syringe barrel. A method of preparing a medication includes providing a component within a syringe barrel and another component within a compartment of a piston insert. A seal is over-molded onto a tip of the insert and an end of a piston sleeve. The sleeve is rotated relative to the insert to establish fluid communication between the compartment and the barrel chamber. | 04-10-2014 |

| 20090247961 | Self-Capping Syringe Assembly With One-Way Valve - A syringe assembly is disclosed which includes a syringe body defining a fluid reservoir, a plunger assembly including a plunger rod and a sealing member supported on the plunger rod, and a luer cap releasably secured to a distal end of the syringe body. The luer cap includes a luer-type connector member and a fluid outlet. A one way valve is supported within the fluid outlet of the luer cap to prevent flow from the fluid outlet back into the fluid reservoir of the syringe body. | 10-01-2009 |
