Inventor
The Tubex Syringe cartridge was developed c. 1943 during World War II by the Wyeth company. It is a drug pre-filled glass cartridge syringe with attached sterile needle, which is inserted in a reusable stainless steel holder (now plastic). The needle protector is removed and is ready for immediate injection in the administration of a drug.
Syringe devices and methods for mixing and administering medication
The invention includes a device having a chamber within a syringe. A fluid passageway extends through a syringe piston. A valve is associated with the passageway controlling fluid passage through the piston. The invention includes a piercing structure having a head segment and a body portion, with a channel through the body portion and through at least one surface of the head without passing through the tip. In another aspect the invention encompasses a method of preparing an agent for administration to an individual. A first component is provided within a syringe and a second component is provided within a vial. A closed valve is associated with a fluid passageway between the vial and the syringe barrel through a piston. Valve repositioning allows fluid passage and sliding of the piston joins the first and second components. Repeated sliding of the piston mixes the components to produce the medication agent.

Pressure actuated valve for multi-chamber syringe applications
Methods and apparatus are disclosed for disposing a valve within a barrel of a conventional syringe to provide, first, a mixing syringe embodiment and, second, a sequential delivery syringe embodiment. Generally, the valve divides the syringe barrel into a proximal and a distal chamber. When used for mixing, the valve is self-displaceable by expansion of decompressing matter disposed within the valve against exterior matter permitting proximal displacement of the valve independent of character of matter in the distal chamber. For sequential delivery, switching of the valve occurs after switch opening causing pressure is relieved, thereby reducing inadvertent uncontrolled flow when the valve opens. In addition, a combination mixing and flush syringe is disclosed whereby a mixing and a flush capability is provided within a conventional syringe.

Attachment for a medical device
A fluid transfer adapter for use with a syringe barrel having a collar with adapter engaging structure and a distally-facing frusto-conically shaped surface is disclosed. The adapter includes a hub having a proximally-facing frusto-conically shaped surface for mating with the frusto-conically shaped surface on the barrel, structure for threadably engaging the hub to the collar of the barrel so that the frusto-conically shaped surface of the hub contacts the frusto-conically shaped surface of the barrel to prevent liquid flow between the surfaces and a fluid transfer having a passageway therethrough, connected to the distal end of the hub so that the lumen is in fluid communication with a conduit in the hub. The passageway includes a frusto-conically shaped edge that aligns with the frusto-conically shaped edge of the barrel, when the adapter is connected to the barrel, thereby reducing waste space.

Multiple ratio fluid dispenser
A double syringe delivery system is disclosed for holding a pair of syringes in a manner so as to accommodate the simultaneous activation of the plunger of each syringe in order to effect simultaneous delivery of the contents of each syringe. The delivery system includes a delivery mechanism for delivering the contents of both syringes to a site of application. The delivery system further includes a support member that is positioned between the two syringe bodies. The elongated support member has resilient, C-shaped clamps on one end of the support member. The clamps are designed to be removably clamped onto the applicator so that the syringe barrels will be held together in a parallel manner. The elongated support member further comprises finger grips. A plunger connects the two syringe plungers so that they can also be simultaneously activated.

A quality control method or system for determining a lubricant coverage at the inside surface of a syringe barrel is provided. The timing for the quality control is not intuitive, yet crucial for patient's safety. The pre-fill test is for a pre-filled (empty or no drug solution), yet oil lubricated, barrel. This pre-fill test needs to be performed within a certain time window immediately following the lubrication. The post-fill test is for a post-filled oil lubricated syringe barrel filled with a solution. This post-fill test needs to be performed after a certain time window has passed from the filling with the solution. The quality control methods could lead to a reduction of health-risks or avoid life-threatening situations associated with syringes that are either below or above the desired lubrication coverage.
