Definitions

  • This invention relates to safety devices for preventing needle stick injuries to individuals who collect body fluid samples from patients. More particularly, the invention relates to devices which permit the transfer of fluid from a collection device such as a syringe to a separate container without the need to mount a needle onto either the collection device or the separate container.
  • blood and other body fluids are drawn into a syringe and must then be transferred to separate containers (e.g., evacuated containers) for laboratory analysis.
  • containers e.g., evacuated containers
  • blood is frequently drawn into a syringe during insertion of a plastic IV catheter into a vein.
  • blood and other body fluids are often drawn from already placed catheters using a syringe.
  • a hypodermic needle is placed on the fluid filled syringe to transfer the fluid through the covering of a separate container, typically an evacuated container.
  • Medical personnel hold an evacuated container in one hand and the fluid-filled needle-bearing syringe in the other hand.
  • the needle of the syringe must then be directed toward the rubber cap typically covering the top of the evacuated container. No shield exists between the needle and the hand holding the container.
  • An improper aim thus easiiy results in a needle stick.
  • the problem is exacerbated by the practice of filling numerous evacuated containers with one syringe since the needle becomes contaminated after the first transfer.
  • Unprotected needles additionally present a high risk to clean-up personnel and others who may come into contact with the contaminated needle after the used needle-bearing syringe has been set aside or discarded.
  • the present invention provides a device which permits such a transfer.
  • the present invention provides a fluid transfer device which substantially eliminates the risk of needle stick injuries by contaminated needles. More specifically, the present invention provides a device which obviates the need to mount an exposed needle onto a collection device to enable the transfer of fluid from the collection device to a separate container.
  • the fluid transfer device of the present invention includes a housing provided with an integral, shielded needle.
  • a first, connection section of the housing is shaped to connect to a needleless collection device.
  • a second, shield section of the housing is shaped to accept a separate container.
  • a first, attached end of the shielded needle of the inventive fluid transfer device is formed integrally with the connection section of the housing.
  • a second, penetration end of the needle extends into and is shielded by the shield section of the housing.
  • the fluid transfer device may be used to substantially prevent the occurrence of needle sticks by contaminated needles to medical personnel transferring fluid and to others exposed to discarded needle-bearing medical devices, as follows:
  • Fluid to be transferred e.g., a patient's blood
  • a collection device e.g., a syringe
  • the collection device is then mounted to the connection section of the housing.
  • a separate container e.g., an evacuated container
  • the shield section of the housing whereby the penetration end of the integral needle penetrates the cap covering the top of the container.
  • Fluid from the collection device is then transferred into the container.
  • the container is removed. Additional containers may then be inserted until all fluid in the collection device has been transferred.
  • the fluid transfer device (with or without the syringe) may be set aside or, preferably, discarded.
  • inventive fluid transfer device permits the transfer of fluid to occur without the use of an exposed needle. Instead, the only needle used remains safely shielded during and after the transfer from a collection device. The risk to medical and clean-up personnel of needle sticks by contaminated needles is thus substantially eliminated.
  • FIGURE 1 is a perspective view of the preferred embodiment of the present invention.
  • FIGURE 2 is another perspective view of the preferred embodiment of the present invention looking into the interior of the shield section of the housing.
  • FIGURE 3 is a side cross-sectional view of the preferred embodiment of the invention.
  • FIGURES 1 and 2 show perspective views of a preferred embodiment of the inventive fluid transfer device.
  • the device includes a housing 10 having an outer surface 12 and an inner surface 14.
  • the inner surface 14 defines a passage 16 through the housing 10.
  • connection section 18 of the housing 10 the inner surface 14 is shaped into a standard female Luer-lock connector to connect to the male Luer-lock end provided on many collection devices.
  • shield section 20 of the housing 10 the passage 16 is sufficiently large to accept a separate container, such as a VacutainerTM.
  • a separate container such as a VacutainerTM.
  • the invention will be described hereafter with reference to a syringe as the collection device and an evacuated container covered with a self-sealing cover as the separate container.
  • the scope of the invention includes needleless collection devices other than syringes and separate containers other than such evacuated containers.
  • the housing 10 is further provided with a short needle 22 having an attachment end 24 formed integrally with the inner surface 14 of the connection section 18 of the housing 12.
  • a sharp penetration end 26 of the needle 22 extends into the passage 16 of the shield section 20 of the housing 12 and is fully covered by the shield section 20.
  • the housing 10 of the inventive fluid transfer device is preferably made of a suitable, non-toxic plastic (e.g., polytetrafluroethylene).
  • the needle 22 may be a standard metal hypodermic needle. However, in the preferred embodiment, the needle 22 may be formed of the same material as the housing 10.
  • the inventive device may be manufactured in a single unit using an injection molding technique and may therefore be manufactured at a relatively low cost. (If a metal needle is utilized, it may be affixed during the molding process.)
  • an operator draws fluid (e.g., blood from a catheter during or after placement in a vein or artery of a patient) into a syringe 28.
  • the syringe 28 is then connected to the connection section 18 of the housing 10 by connecting the male Luer-lock end 30 of the syringe 28 to the female Luer-lock-shaped inner surface 14 of the connection section 18 (see FIGURE 3).
  • An evacuated container 32 is then inserted into the shield section 20 whereby the penetration end 26 of the needle 22 pierces the self-sealing cap 34 of the evacuated container 32 and fluid drains into the evacuated container 32 until the syringe 28 is empty or the container 32 is full.
  • the evacuated container 32 is then removed from within the shield section 20. A new container may be inserted if fluid remains to be transferred from the syringe 28. After all fluid has been removed from the syringe 28, the syringe 28 and fluid transfer device may be disposed or set aside as a single unit or separated. The needle 22 remains safely shielded even after disposal.
  • the inventive fluid transfer device 10 provides a cost-efficient method of substantially eliminating the risk of needle stick injuries by contaminated needles to medical and clean-up personnel both during and after fluid transfer from a collection device to a separate container.
  • the inventive device may be adapted for use with collection devices which do not include a male Luer-lock section by reshaping the inner surface 1 and/or outer surface 12 of the connection section 18 of the housing 10 to provide alternate connection opportunities.
  • the connection section 18 may be adapted to snap onto a collection device. Accordingly, it is to be understood that the invention is not to be limited by the specific illustrated embodiment, but only by the scope of the appended claims.
