Devices having male connectors for preventing connection to non-compatible female connectors are described. An exemplary male connector includes an elongate tip and a collar disposed coaxially around the elongate tip including a plurality of ribs disposed on either an inside surface or an outside surface of the collar for preventing entry of a non-compatible female connector into a channel formed between the elongate tip and the collar. One or more embodiments pertain to a device with a male connector and a compatible female connector including a threaded portion for engaging a corresponding threaded portion of the male connector.

A thermoplastic elastomer stopper that meets the desired material properties of a stopper for a syringe assembly is disclosed. The compression set of the thermoplastic elastomer stopper of the present disclosure is &#x2264;50% when measured at 25% compression for 22 hrs at 70 degree C. The hardness of the thermoplastic elastomer stopper of the present disclosure is 40-70 Shore A. The viscosity of a thermoplastic elastomer stopper of the present disclosure is &#x2265;70 Pa&#xb7;s at 1,000 sshear rate, &#x2265;12.0 Pa&#xb7;s at 10,000 sshear rate, and &#x2265;3.0 Pa&#xb7;s at 50,000 sshear rate when measured using a capillary rheometer at 205 degree C. (Die: Roundhole 20 mm length/1 mm diameter/180 degree inlet, Piston: d=15 mm, and melting time=7 min). The present non-lubricated stopper exhibits the required functional performance of a lubricated stopper.

Leak-free stopper having low breakloose and sustaining forces

A syringe packaging system that includes a packaging member defining a first compartment, a second compartment, and a third compartment that are in gaseous communication theretogether is disclosed. The first compartment is structured to receive a syringe barrel therein, the second compartment is structured to receive a plunger rod therein, and the third compartment is structured to receive an oxygen absorber therein. With the packaging member enclosing the syringe barrel, the plunger rod, and the oxygen absorber, the oxygen absorber is adapted to draw oxygen from within the syringe barrel and to absorb oxygen contained within at least one of the first compartment, the second compartment, and the third compartment of the packaging member. The syringe packaging system of the present disclosure also allows for reduced storage space of a syringe assembly.

Compositions including recycled resin components and medical devices and components made form such compositions are disclosed. The compositions and medical devices are characterized as biocompatible and sterilization stable. In one or more embodiments, the compositions include a recycled resin component and may include one or more of an anti-oxidant component, slip additive component, anti-static component, impact modifier component, colorant component, acid scavenger component, X-ray fluorescence agent component, radio opaque filler component, surface modifier component, melt stabilizer component, clarifier component, processing aid component and reinforcing agent component. Methods of forming medical articles and components are also disclosed.

Recycled resin compositions and disposable medical devices made therefrom

A plunger for a retracting needle syringe includes a hollow elongate body portion having a proximal end, a distal end, and a side wall therebetween defining a cavity. The distal end includes a distal wall having an inside surface and an outside surface. A stopper, at the distal end of the body portion, includes a peripheral portion performing a seal with the inside surface of a syringe barrel and at least one radial element extending from about a center of the outside surface of the distal wall to the peripheral portion. The distal end of the body portion includes at least one primary chamfer in the cavity at an intersection of the inside surface of the distal wall and the side wall. The chamfer is positioned under the at least one radial element for supporting the distal wall and the radial element when a hollow sleeve in the syringe barrel cuts through the end wall plunger. A secondary, smaller chamfer on each side of the primary chamfer is also provided.

Plunger for retracting needle syringe

An adapter is provided for enabling the single-handed use of a syringe for aspiration. An assembly including such an adapter is also provided. The adapter includes an elongate body portion including a first end portion which functions as a thumb pad and a second end portion secured to the syringe barrel. A winged member is secured to the syringe plunger and includes a pair of flanges extending outside the adapter. The syringe plunger may be retracted using only one hand by pulling the flanges of the winged member with the index and middle fingers while maintaining the thumb upon the first end portion of the adapter.
