Filed:

Mar 15, 2001

Appl. No.:

09/809469

Inventors:

A. Wesley Prais - Hewitt NJ
Judith L. Doyle - Upper Saddle River NJ
Steven L. Koziol - Columbus NE
Frederic Perot - Grenoble, FR

Assignee:

Becton, Dickinson and Company - Franklin Lakes NJ

International Classification:

A61M 532

US Classification:

604274, 206365

Abstract:

A syringe assembly including a needle cannula having a five-beveled point and a needle shield formed of a styrene block poly(ethylene/butylene) thermoplastic elastomer which significantly reduces needle penetration force and may reduce the cycle time for gas sterilization. The multi-beveled needle cannula point includes a primary bevel, a pair of tip bevels and a pair of middle bevels each intermediate the primary bevel and a respective tip bevel, wherein the angles of rotation of the primary bevel and the intermediate bevels are substantially equal resulting in reduced heights of intercepts between the bevels, thereby reducing needle penetration force. The needle shield maintains the sharpness of the needle cannula during application, sterilization and removal of the shield and it is believed that the needle shield will also reduce the cycle time of gas sterilization as compared to rubber needle shields and vulcanizate thermoplastic elastomers.

Appl. No.:

9/040067

Inventors:

Judith L. Doyle - Upper Saddle River NJ
Steven L. Koziol - Columbus NE

Assignee:

Becton Dickinson and Company - Franklin Lakes NJ

International Classification:

B21G 316

US Classification:

163 5

Abstract:

A hypodermic needle featuring a multi-beveled point geometry is disclosed. In one embodiment, the multi-beveled point features a primary bevel, a pair of tip bevels, and a pair of middle bevels each intermediate the primary bevel and a respective one of the tip bevels. The primary and middle bevels are provided at angles of inclination, measured between the central axis and a reference plane that are substantially identical. The tip bevels are formed at an angle of inclination respective to the central axis which is not equal to the angle of inclination at which the primary and middle bevels are formed. The resulting five-beveled point geometry contributes to a more continuous bevel face free of abrupt intercepts or transitions between the respective bevel faces, lessening the penetration force required to urge the needle point through skin, flesh, or other material.
