Definitions

  • a multipurpose safety device to prevent needle stick injury and to prevent injuries while cutting an ampoule or opening a vial seal.
  • Injuries are occupational hazards of the medical profession. Injuries caused by used needle sticks or while cutting a glass ampoule or while opening the metal seal of a vial are quite common. The injured finger is an opening for germs to enter. Infections like hepatitis and HIV could be transmitted from contaminated products or fomites during handling. To avoid such injuries it is best to adopt safe practices or devices, which will protect against or minimize these injuries. A simple, economical, easily available, ready to use, multi purpose safety device would thus have a higher usage. In an earlier patent the concept of a needle stick injury prevention device was introduced. Here an upgraded version of the safety device is being introduced with features that will protect against a variety of injuries.
  • Indian patent number 203913 describes one such safety device for prevention of needle stick injuries.
  • the said device does not have the safety features for protecting against injuries that can happen while opening the metal seal of a vial or cutting a glass ampoule.
  • the new device has improved upon the previous version, by introducing an open rimmed slot at one end of the device, where the needle cover can be pushed in sideways. Further the new device introduces features of safety for opening a metal seal of a vial and cutting a glass ampoule.
  • a glass vial has a rubber cap, which is fixed to the mouth of the vial by an aluminum seal with a flip-top which covers the central rubber portion of the cap.
  • the aluminum seal makes the vial air tight and leak proof.
  • a central circular part of the aluminum seal covers the centre of the rubber cap and protects it from contamination. It can be flipped open when required.
  • a needle is introduced through the central portion of the rubber cap after flipping open the central aluminum top.
  • the doctor or a nurse will use finger nail to flip the aluminum cover, resulting in an injury caused by the sharp edge of the cut aluminum cover.
  • the new invention also provides for safe and proper opening of the aluminum flip-top part of the seal. And it also helps in safe and complete removal of the metal seal of the vial and in uncovering of the rubber cap of the vial.
  • the neck of the ampoule is scored with a metal file with a serrated edge.
  • a nurse uses her own bare thumb and finger to break off the top portion, frequently injuring herself.
  • a blunt instrument is struck to the top part of the ampoule to break it. This causes glass pieces to fly or fall into the ampoule, either injuring someone or contaminating the medicine.
  • the added advantage of the new invention is that it allows the safe breaking of the glass ampoule preventing injuries and contamination Objective of the invention:
  • the objective of this invention is to upgrade the previous patent with the addition of safety features for opening the metal seal of a vial and cutting a glass ampoule in a manner that will protect the user's hand from accidental injuries, in addition to improve the ease of parking of the needle cap or cover.
  • the design is simple, flat and compact, economical, easy to package with needle - needle cover - syringe assembly, easy to sterilize, transport, use and dispose off.
  • the design should be versatile, from the point of view that it can accommodate various different designs of the needle cover, and is not dedicated to a particular design, thereby allowing the manufacturers the freedom to manufacture or continue to manufacture their own particular designs of the needle covers.
  • the aim is to allow the reuse of a precious resource, the needle cover, which protected the user from the accidental injury till before the uncapping of the needle for the use, while keeping the user's fingers and hand away from the potentially contaminated needle tip. And also to keep the needle-syringe assembly free of any encumbrances, so that the free and proper use of the needle - syringe assembly is not hampered.
  • the present invention consists substantially of a flat strip with slots at one end.
  • the slot near the end is open at the edge partially and the design of this slot substantially corresponds to the outer design of a needle cover that needs to be parked or accommodates the needle cover effectively.
  • Another slot corresponds to the outer design of the needle hub to help disengage a tight fitting needle from the syringe.
  • the edges of the flat strip are raised to create a guard rail and the surface is optionally grooved.
  • the other end, also called the grip end is beveled to help open the metal seal of a rubber cap of a bottle or vial. This end may be optionally angulated or curved.
  • Fig.l describes the top view of the flat surface of the device.
  • Fig.2 describes the top view of the flat surface of the device.
  • Fig 3 A describes the oblique view of the device and the usage of the device to disengage the needle from the syringe tip.

Abstract

Le dispositif de sécurité universel pour prévenir les blessures par piqûres d'aiguilles et les coupures lors de l'ouverture d'une ampoule ou d'un flacon serti selon l'invention se compose essentiellement d'une languette plate munie d'encoches à une extrémité, à l'opposé de l'extrémité de préhension. L'encoche proche de l'extrémité est partiellement ouverte au bord et sa forme correspond sensiblement à la forme extérieure d'un protège-aiguille qui doit être rangé ou s'adapte efficacement au protège-aiguille. Une autre encoche correspond à la forme extérieure d'une embase d'aiguille et aide à dégager une aiguille ajustée par serrage de la seringue. Il y a une troisième encoche, qui porte une lime à une extrémité et/ou sur un côté pour entailler une ampoule en verre. Les bords de la languette plate sont surélevés pour créer une barrière de sécurité et la surface est éventuellement rainurée. L'autre extrémité, également appelée extrémité de préhension, est biseautée pour faciliter l'ouverture du sertissage métallique du bouchon en caoutchouc d'une bouteille ou d'un flacon. Cette extrémité peut éventuellement être oblique ou incurvée.
