Iv-catheter insertion device Title: Iv-catheter insertion device.Abstract: The present disclosure is directed to a catheter insertion device, which has a catheter hub at the proximal end of a catheter, a tubular needle hub, at which a hollow needle is fixed and extends through the catheter hub and the catheter in a ready position such that the needle tip projects over the distal end of the catheter, a protective barrel which is received in the tubular needle hub in the ready position and is releasably connected to the catheter hub, and a pressure spring arranged between the needle hub and the protective barrel and which displaces the needle hub and the protective barrel apart from each other in an axial direction, wherein a manually operable holding member is provided between the needle hub and the protective barrel, and holds the needle hub in the ready position at the protective barrel against the bias of the pressure spring, so that after the holding member is released, the pressure spring moves the needle hub into a protective position in relation to the protective barrel, in which position the needle is positioned in the protective barrel. ...
USPTO Applicaton #: #20120271235 Inventors: Juergen Fuchs, Hermann Riesenberger
The Patent Description & Claims data below is from USPTO Patent Application 20120271235, Iv-catheter insertion device.
This is a national phase application under 35 U.S.C. §371 of PCT Application No. PCT/EP2010/006909 filed Nov. 12, 2010, which claims the benefit of German application No. 10 2009 052 962.4 filed Nov. 12, 2009, the contents of each of which are expressly incorporated herein by reference.
In the Figures, reference numeral 1 refers to a catheter hub which, in the embodiment shown, comprises a distal part 1.1 and a proximal part 1.2, between which an automatically self-closing valve 2 in the form of a valve disc is held, the valve 2 being provided with a central slit or slits which extend preferably radially out from the centre of the valve 2 and which is or which are closed in the closed position of the valve. At the distal end of the catheter hub 1, a catheter tube 1a is held in the hub part 1.1, preferably by a metal bushing. At the proximal end of the catheter hub 1, a Luer thread 1.3 is formed at the catheter hub part 1.2. The two parts 1.1 and 1.2 of the catheter hub 1 are joined to each other by bonding or welding. However, it is also possible to provide a one-piece catheter hub 1.
In the ready position, elbow-shaped portions at the distal wall portions 7.2 and 7.3 of the arms of the spring clip 7 abut behind a shoulder 1.4 on the inner circumference of the catheter hub 1, so that the spring clip 7 is held in the catheter hub 1 until the needle tip 5.1 is positioned inside the spring clip 7 in the protective position (FIG. 3) and the needle shaft releases the radial spread of the distal wall portions 7.2 and 7.3 of the spring arms of the spring clip. In the protective position, the distal wall portions of the spring clip 7 spring radially inwards so that they are released from the shoulder 1.4 in the catheter hub 1, and the protective barrel 3 with the spring clip 7 held thereon can be released from the catheter hub 1. as FIG. 7 shows.
