Having Guard On Piercing Conduit For Protecting Body Entering Conduit Patents (Class 604/162)
  • Patent number: 11833337
    Abstract: A Hypodermic Needle Safety Guard intended for sharps prevention and safer hypodermic needle use during all stages of an injection process. The Safety Guard may include two symmetrically positioned multi-featured arms that include spring tension, multiple hinges and needle locks. These arms may connect a proximal Luer body and a distal alignment tip thereby enabling the guard to open, close and lock on a needle when manual pressure is applied. The Guard position during hypodermic needle use tends to prevent sharps injury by adjusting the exposure of the Needle tip.

  • Patent number: 8313469
    Abstract: An I.V. catheter assembly and needle safety device are disclosed which allow for the safe removal of a needle from a catheter assembly. The safety device includes a locking assembly which includes lock housing a rotatable locking member and a locking clip. The needle and the locking member are configured such that withdrawal of the needle from the catheter assembly effects rotation of the locking member. The locking clip is positioned and configured to obstruct rotation of the locking member after the needle has been retracted within the housing to obstruct re-advancement of the needle.

  • Patent number: 8251975
    Abstract: A catheter for introduction and removal of fluids from a body and tunneling device therefor, the catheter has a body having a first conduit for removing fluid from the body and a second conduit for delivering fluid to the body wherein at least a part of each of the conduits is integrally formed within a first end of the body of the catheter and extends along side one another. The first conduit extends beyond the second conduit and forms a terminal point of the first end and defines a first opening thereat and the second conduit extends to a point short of the terminal point defining a second opening. A bumper portion is adjacent the second opening extending toward the terminal point. Another part of each the first and the second conduits are disjoined and form part of a second Y-shaped end. The tunneling device has a channel to removably receive the catheter.

  • Patent number: 8235944
    Abstract: A medical device for placement of regional anesthesia catheters. The device comprises a hollow shaft needle, a plunger attached to the posterior end of the needle, a housing dimensioned so that plunger can slide inside the housing with friction, a regional anesthesia catheter preloaded inside the needle, a protective cover sheath covering the catheter, and a catheter adaptor attached to posterior end of the sheath and the catheter. The medical device allows a practitioner to quickly and effectively place a regional anesthesia catheter inside an organism without the use of an assistant, and with minimal risk of contaminating the catheter before it enters the organism's body. At the end, the needle is withdrawn inside the housing and disposed.

  • Patent number: 8162889
    Abstract: A needle assembly includes a mounting structure and a needle mounted on the mounting structure and extending outwardly from the mounting structure. The needle has a longitudinal axis, a sharp end and a central axial passageway. A safety shield is associated with the needle and includes a tubular housing having distal and proximal ends. The distal end of the housing has a funnel-shaped surface. A reset key is configured to engage the distal end of the housing. The reset key includes a support. A shaft extending from the support is adapted for inserting into the distal end the housing. The funnel-shaped surface guides the shaft into the housing to register the reset key with the safety shield.

  • Patent number: 8162904
    Abstract: A protector is attached for use to a needle body having a main needle body and an enlarged-diameter section having an outer diameter greater than that of the main needle body. The protector includes a platelike protector body made of a metal material. The protector body includes a first section formed with a first hole adapted to receive the needle body when the needle body is passed therethrough, a second section formed with a second hole, and a third section adapted to connect the first section and the second section. The second hole of the second section is provided with a tubular portion that permits the main needle body to pass therethrough, but prohibits the enlarged-diameter section from passing through the tubular portion. In a state in which the protector covers the needle tip, the tubular portion comes into abutment against the enlarged-diameter section, thus prohibiting the needle body from moving toward the proximal side.

  • Patent number: 8096977
    Abstract: A protector comprising an inner tube, a lid connected to an upper opening of the inner tube through a hinge, and an outer tube for holding the inner tube in an inner cavity part of the outer tube. A blood collecting needle to which a tube is connected is stored in the inner tube. The inner tube comprises an annular seat face which seats on the base end part of a hub formed integrally with the blood collecting needle when the blood collecting needle moves downward. An operation lever extending downward is installed at the side of the lid, and an end part of the operation lever is slightly projected outward. When the blood collecting needle is moved, the inner tube is pulled integrally with the tube by the annular seat face to be slid relative to the outer tube until the end part abuts on the lower end part of an operation hole. Then, the lid is closed and the blood collecting needle is stored in the inner tube.
