Definitions

  • AGAINST NEEDLE TIP in that it has a small flexible tube for infusions, being possible to prevent the blood escape with a simple strangulation, what is possible with only one of your own hand until an infusion or its lid is connected.
  • WP can obtain a great ease concerning its attachment to the patient's body and the exemption of blood leakages, surpassing the utility model: "Single Outlet Vascular
  • Catheterism Device which leaks due to holes on its latex body (flexible glove curve), as in conventional catheters by several reasons. Further, it shelters on its body a protector against the needle tip, which is taken to the needle end preventing it from its tip after the catheter attachment.
  • FIG.1 - Demonstrates the position for the usage of the "INTRAVENOUS CATHETER WITH FLEXIBLE EXTENDER AND PROTECTOR AGAINST NEEDLE TIP".
  • FIG. 2 Scheme of the catheter post-insertion moment m intravenous via, showing the flexible extender strangulation by a hand. It is also illustrated in the drawing the action of the protector against the needle tip
  • FIG. 3 Separation of the catheter from the opening: the protector is connected to the catheter until the safe cord is completely extended, preventing the separation between the protector and the rest of the device, putting it in the functional position
  • FIG. 4 - Shows the semi-flexible handle in use
  • FIG. 5 - Shows the instrument in the cylindrical, small and hermetically closed casing, sheltering a needle, the catheter and the flexible extender. Finally, the support chute occupied by the components, completing the components disposition drawing.
  • FIG. 6 - Shows the device usage position.
  • FIG. 7 The separated parts of the invention.
  • FIG. 8 - Shows the device functioning, with the chute involving the needle after the catheter securement.
  • the guide needle has a length which passes through all the flexible extender length and reaches the other end, the catheter tip. Relatively thin needles may have cleft for a better view of the blood flow.
  • the rigid (or flexible) catheter canula base is connected to the flexible tube for infusions (7), having also an internal funnel and an external cover surrounding it.
  • the flexible tube for infusions is attached to the catheter canula base (4).
  • the needle protection claw is composed of two bent pressure blades, directed against the needle in order to isolate its tip, and of two bent flanges against the wall of the extender opening for infusions (8).
  • the protector When the stopper cord (13) is extended, the protector is separated from the opening of the extender for infusions (8) and it automatically positions itself over the needle tip which is already disconnected from the catheter.
  • the catheter holder is a concave handle which shelters the needle, the extender and the tip protector by surrounding them, all of them connected in its inner part.
  • the support chute has its lateral rims semi-flexible. It has holes (20) and bores (22) for limiting the chute travel.
  • the support chute bores are intended to engage with the protuberances (21) and to limit its travel in the handle-casing.
