Definitions

  • the Needlestick Prevention Act was enacted by the United States Congress and went into effect on November 6, 2000 with a requirement of compliance by April 18, 2001.
  • the U.S. Congress directed the Occupational Safety and Health Administration, hereinafter "OSHA", to administer the Act.
  • OSHA then promulgated revised regulations relating to the control of bloodborne pathogens (Bloodborne Pathogens Standard, 29 C.F.R. Section 1910.1030). This revised Bloodborne Pathogens Standard applies to all occupational exposure to blood or other potentially infectious material.
  • the Needlestick Prevention Act is an attempt to prevent the 600,000 to 800,000 inadvertent exposures to bloodborne pathogens that occur each year.
  • Needlesticks occur at a rate of 300 inadvertent exposures per 100 healthcare treatment beds each year.
  • the Act requires healthcare facilities under the jurisdiction of OSHA to use safer medical devices, such as sharps with engineered sharps injury protection and needleless systems.
  • This Act and other OSHA directives require an annual review of a facility's exposure control plan and the use of safer medical devices to help reduce needlesticks and other sharps injuries.
  • the Needlestick Safety and Prevention Act as well as other state rules and regulations, have encouraged the development of "safety syringes".
  • the purpose of the safety syringe is to keep the tip of the needle or fluids in the syringe from inadvertently contacting anyone before and after a medication has been administered to a patient.
  • safety syringe designs such as those that have retractable or sheathed needles.
  • One particular type of safety syringe includes an extendable, sliding sheath design where the sheath moves from a retracted position to an extended position that surrounds the needle after it has been used.
  • Examples include the Monoject® safety syringe, manufactured by Kendall-LTP, also know as The Ludlow Company LP, a business of Tyco
  • a radiopharmacy typically dispenses a liquid radiopharmaceutical in a conventional syringe, which is then placed in a pharmaceutical pig for transport to a medical facility.
  • the pharmaceutical pig reduces unwanted exposure from the radioactive material and protects the conventional syringe from damage during transport.
  • the pharmaceutical pig is opened, the conventional syringe is removed and the liquid radiopharmaceutical is administered to a patient.
  • the used syringe is put back in the pharmaceutical pig and returned to the radiopharmacy for disposal.
  • Residual blood and liquid radiopharmaceutical can leak from the conventional needle to contaminate the inside of the pharmaceutical pig and create an increased exposure risk. Moreover, before and during the securing of this contaminated conventional needle within the pharmaceutical pig, accidental exposure to bloodborne pathogens can occur.
  • the "danger zone" is specifically defined as the time period from the point of patient injection to the point of disposing of the syringe. Fifty percent (50%) of all inadvertent exposures to bloodborne pathogens occur after the patient is injected and twenty percent (20%) occur when disposing of the syringe into a sharps container.
  • Radiopharmacies are independently owned and others are owned and operated in nationwide networks by Cardinal Health, Inc., having a place of business at 7000 Cardinal Place, Dublin, Ohio 430017 and Mallinckrodt Inc., a business of Tyco International, Ltd., having a place of business at 15 Hampshire Street, Mansfield, Massachusetts 02048.
  • Pharmaceutical pigs currently used with syringes are elongate devices sized to enclose a single conventional syringe that holds a dose for a single patient.
  • Conventional pharmaceutical pigs are available from Biodex Medical Systems, Inc., having a place of business at 20 Ramsay Road, Shirley, New York 11967-0702 and are available from Cardinal Healthcare Ltd.

Abstract

L'invention concerne un dispositif d'étanchéité pour seringue de sûreté et un procédé d'utilisation du dispositif. Le dispositif combine une seringue de sûreté et un bouchon. La seringue de sûreté comprend un cylindre, une aiguille, un piston et une gaine de l'aiguille. La gaine de l'aiguille peut être déplacée entre une position rentrée dans laquelle l'aiguille est exposée et une position déployée dans laquelle l'aiguille est protégée, la gaine de l'aiguille délimitant une extrémité ouverte. Un bouchon peut être inséré dans l'extrémité ouverte de la gaine de l'aiguille lorsque cette dernière se trouve dans la position déployée. Le dispositif d'étanchéité peut également comprendre un boîtier pharmacologique présentant une base et une coiffe, lesquelles délimitent une section centrale creuse pouvant recevoir la seringue de sûreté. Ainsi, la seringue de sûreté, dont la gaine de l'aiguille est fermée par un bouchon, peut être isolée de manière étanche à l'intérieur du boîtier pharmacologique pour empêcher une fuite ou une exposition accidentelle.
