Patent number: 7303547Abstract: The present invention is a safety syringe for use with a plurality of interchangeable needles. The plurality of needles may be inserted by the user into the safety syringe for use. In operations, the user selects the desired needle, e.g., a needle having a particular gauge or size or of a particular type. The user inserts the needle (14) into a safety syringe (10) comprising a barrel (6), a needle assembly area (18) located within or attached to the barrel and a plunger (66). The needle couples to the syringe by a number of means. For instance, a locking mechanism (20, 22) may be used by which a needle hub located within the needle assembly has an area adapted to mate with a corresponding area on the needle. Or, the needle may be formed as part of a separate needle assembly, whereby the user will place the entire needle assembly onto the end of the syringe barrel.Type: GrantFiled: March 14, 2006Date of Patent: December 4, 2007Assignee: MedSafe Technologies LLCInventors: William B. S. Pressly, Sr., Charles A. Vaughn, Sr., G. Samuel Brockway, Thomas R. Ellis

Patent number: 7255685Abstract: An intravenous catheter placement device having a hollow body and a nose on one end of the hollow body. A needle hub fits within the nose and contains a needle embedded therein. A catheter is free to slide along the needle and substantially covers the shaft of the needle. Winged beams on the needle hub include catches and release tabs that cooperate with slots in the nose to retain the needle hub in the nose. A magnified transparent verification cavity in the needle hub provides for viewing blood flash in the cavity to verify that the intravenous catheter is inserted into the correct location. An energy storage device in contact with the needle hub releasably retains the needle hub to prevent premature projection of the needle hub into the hollow body. Upon insertion of the intravenous catheter and introducer needle into a patient, depressing the release tabs triggers the needle hub and blunts the needle within the catheter and projects the needle hub and embedded needle into the hollow body.Type: GrantFiled: August 9, 2005Date of Patent: August 14, 2007Assignee: MedSafe Technologies LLCInventors: William B. S. Pressly, Sr., John M. Mitnick

Or, the needle may be formed as part of a separate needle assembly, whereby the user will place the entire needle assembly onto the end of the syringe barrel. During use, the user operates the syringe, using one hand to depress the plunger, which ultimately causes a spring to propel the needle into the barrel of the syringe.Type: GrantFiled: February 18, 2000Date of Patent: March 21, 2006Assignee: MedSafe Technologies, LLCInventors: William B.

Publication number: 20040064106Abstract: A syringe apparatus and process for using the same is provided, the syringe apparatus having a barrel, a plunger movable within the barrel, a needle assembly attached to an end of the barrel and having a passageway therethrough, a deformable base positioned within the barrel, flexible supports included on the deformable base, a spring within the passageway of the needle assembly, a hollow needle passing through the passageway, an enlarged head on the needle, and a rupturable web on an end of the plunger, whereby when the plunger moves through the barrel toward the needle assembly, a fluid can be moved from the barrel through the hollow of the needle, and continued movement of the plunger flexes the supports and moves the deformable base downwardly until such time a sufficient force is imparted to the rupturable web by the enlarged head to tear the web, the deformable base then releasing the needle due to force applied by the spring to project the needle into the interior of the plunger.Type: ApplicationFiled: July 1, 2003Publication date: April 1, 2004Inventors: William B.

Patent number: 6605073Abstract: A syringe apparatus and process is provided for retracting a needle from a hypodermic syringe following the completion of an injection. The hypodermic syringe has a plunger which, upon completion of the injection, is forced downwardly against a needle support deformable base, severing sacrificial supports. An end portion of the needle tears a base portion of the plunger and propels the needle into a hollow region of the plunger such that the needle is contained entirely within the plunger.Type: GrantFiled: June 13, 2000Date of Patent: August 12, 2003Assignee: MedSafe Technologies, LLCInventors: William B.

Patent number: 5211629Abstract: A hypodermic syringe is provided having a barrel with a movable plunger therein to inject a fluid through a hollow needle thereof which is housed within a passageway of a needle assembly that is attached to the barrel by ultrasonic welding means or other permanent attaching means. Positioned between sacrificial supports in the needle assembly and the barrel is a deformable base. The deformable base houses an enlarged head of the needle which is in contact with energy storage means within the passageway of the needle assembly. The plunger has a rupturable boot thereon which, upon completion of an injection, contacts a deformable base forcing it downward and severing a sacrificial support means within the needle assembly thereby permitting the base to move the enlarged head of the needle downward, until it is blocked by the passageway. Further movement of the base forces the enlarged needle head from the base and into contact with the rupturable boot.Type: GrantFiled: December 23, 1991Date of Patent: May 18, 1993Inventors: William B. S. Pressly, Charles A. Vaughn, Sr.
