Abstract

A safety syringe sealing system and method of use is disclosed. The safety syringe sealing system includes the combination of a safety syringe and a plug. The safety syringe includes a barrel, a needle, a plunger and a needle sheath. The needle sheath is movable between a retracted position where the needle is exposed, to an extended position where the needle is protected, the needle sheath defining an open end. There is a plug that is engageable with the open end of the needle sheath when the needle sheath is in the extended position. The sealing system can also include a pharmaceutical pig, having a base and cap, where the base and cap define a hollow center section that is capable of receiving the safety syringe. Therefore, the safety syringe, having a plugged needle sheath, may be sealed within the pharmaceutical pig to prevent leakage and inadvertent exposure.

Description

 Safety syringe sealing system and method of use {A SAFETY SYRINGE SEALING SYSTEM AND METHOD OF USE}

 The Needlestick Prevention Act was enacted by the US Congress and entered into force on November 6, 2000, with a request for approval by April 18, 2001. The Congress established the Occupational OSHA, the Occupational Safety and Health Administration. Accordingly, OSHA has issued a revised provision on the control of pathogens in the blood (Bloodborne Pathogens Standard, 29C.F.R.Section 1910.1030). The revised standard for pathogens from this blood applies to all occupational exposures to blood or other potentially infectious substances. Needle bar prevention legislation attempts to prevent inadvertent exposure to bloodborne pathogens from 60,000 to 80,000 blood, which occur every year. Needle bar events occur at a rate of 300 inadvertent exposures per 100 health care beds per year. The law requires health care facilities under OSHA's jurisdiction to use safer medical devices, such as machined needle guards and needleless devices. This law and other OSHA orders require annual review of the instrument's exposure control plans and the use of safer medical devices to reduce needle bars and other sharps. As with other state rules and provisions, needle bar safety and prophylaxis have encouraged the development of safety syringes. The purpose of a safety syringe is to prevent the inadvertent incorporation of fluids with the tip of the needle or fluid in the syringe before or after the medication is administered to the patient.

 There are many safety syringe models, such as having a retracted or wrapped needle. One particular type of safety syringe includes a form of an extensible sliding lid, which moves from the retracted position surrounding the needle to the protruding position after the syringe has been used. Examples include, among others, Two Ludlow Park Drive, Monoject® safety syringe manufactured by Kendal-LTP and Tyco International Ltd, known as The Ludlow Company LP, with sales office in Chicopee Massachusetts01022, 1 Becton Drive, Franklin Lakes, New Jersey 07417 Getting Guard® syringes from Getting Technologies, Inc. with "The Safety-Lok ™" at Becton-Dickinson and Company, 1 Streamside Place, Spring Mills, Pennsylvania 16875, 22 Dubon Court, Farmingdale, New York Includes Univec Sliding Sheath® syringes from Univec Inc.

Also disclosed are safety syringes with extendable caps: U.S. Patent No. 4,994,045, registered to Ranford on February 19, 1991; U.S.Patent No. 4,998,924, which was registered with Ranford on March 12, 1991, and incorporated on this basis; U.S.Patent No. 4,743,233, registered with Schneider on May 10, 1998; Registered by Talonn et al on April 4, 1995, the U.S.Patent No. 5,403,287; On 17 November 1992, U.S.Patent No. 5,163,916; U.S.Design Patent No.313,470, incorporated by reference from Talonn et al, on January 1, 1991; U.S.Design Patent No.344,355, filed on February 15, 1994, with Talonn et al.

Radiopharmaceuticals typically administer liquid radiopharmaceuticals to traditional syringes, which are placed in pharmaceutical pigs for transportation to the pharmacy. Medical molds reduce unwanted exposure from radioactive material and protect traditional syringes from damage during transportation. After delivery, the medical template is opened and a liquid radiopharmaceutical is administered to the patient after the traditional syringe has been transferred. The used syringe is placed back into the medical mold and returned to the radioactive dispensing chamber for disposal. Remaining blood and liquid radiopharmaceuticals leak from traditional needles, contaminating the interior of the medical mold and increasing the exposure risk. In addition, sudden exposure to pathogens from the blood may occur prior to and during the protection of contaminated needles within the medical mold. In fact, the danger zone is specifically defined as the time from when the needle is injected into the patient to when the syringe is discarded. 50% of all inadvertent exposure to the pathogen from the blood occurs after injecting the patient, and 20% occurs when the syringe is thrown into the syringe barrel.

Some radiopharmaceuticals are independently owned and others are owned and operated nationwide by Cardinal Health with offices at 7000 Cardinal Place, Dublin, Ohio 430017 and Mallinckrodt with offices at 15 Hampshire, Mansfield, Massachusetts02048. Medical molds used in modern syringes are thin, long devices that are standardized to enclose one traditional syringe that takes one dose for a patient. Traditional medical molds are available from Biodex Medical Systems, Inc., with sales offices at 20 Ramsay Road, New York 11967-0702, and from Cardinal and Healthcare Ltd.
