Abstract
ABSTRACT OF THE DISCLOSURE
Disclosed is an improved subclavian vena puncture device comprising the combination of a straight hollow lower bevel tipped needle having a syringe removably secured to the upper end thereof and having a diagonally upwardly disposed hollow catheter guide tube fixed to and extending diagonally upwardly from one side of the upper portion of the needle. The catheter guide tube is closed by inserting a metal stylet telescoped therein to a position short of its juncture with the hollow needle, and blood may be removed by the syringe from the straight hollow needle. The soft plastic catheter may now be disposed in the vein with its upper end portion extending through the catheter guide tube with the free end portion thereof closed by any suitable means. The catheter is then connected to a conventional intravenous means through which blood or medicants may be provided to the patient through the catheter and into the vein of the patient when and as required.

Description
103~
The present invention provides a method for intro-aucing a catheter into a patient for intravenous provision of blood and/or medicants comprising the steps of: introducing into the subclavian vein of the patient a subclavian vena puncture device comprising a straight hollow needle having a bevelled lower tip and a syringe removabl~ connected to the upper end thereof, an equally sized hollow catheter guide tube fixed to one side of the upper central portion of the needle extending angularly upwardly therefrom, ana a catheter temporarily closed by a method stylet therein and telescoped downwardly neatly through the catheter guide tube to a position ~:
having its lower end disposed just short of the lower end of the catheter guide tube thereby leaving the main portion of -the straight hollow needle clear whereby to permit blood to be aspirated from the subclavian vein responsive to partial withdrawal of the piston of the syringe; pushing the temporarily closed catheter downwardly from the catheter guide tube into and through the lower portion of the needle and into the sub-clavian vein of the patient to a distance selected by the :surgeon; removing the stylet from the catheter to provide a :`
free passageway therethrough; immediately capping the free end of the catheter; removing the syringe from the upper end of the needle and capping the top of the needle; and gently removing the straight hollow needle from the patient~s vein by sliding the needle upwardly therefrom, leaving the catheter in the vein through the upper end of which blood and/or medicants may be provided to the patient when and as required employing conven-tional intravenous (I-V) means, The present invention also provides a subclavian vena puncture device comprising a straight hollow needle having a bevelled lower tip and a syringe removably connected to the upper end thereof, an equally sized hollow catheter guide tube fixed to one side of the upper central portion of the needle mb/~

The improved subclavian vena puncture device 10 dis-closed in the drawings comprises the combination of a straight hollow needle 11 having a lower beveled tip 11~ and an upper end 111 which is removably secured by such means as a suitable con-nector 12 to the lower stem 13~ of a syringe 13. The upper cen-tral portion of the hollow needle 11 has a substantially equal sized hollow cath~ter guide tube 14 ~ixed thereto at 140 and 3X-tends angularly upwardly from one side of the said needle 11.

This provides the surgeon with an opportunity to be assured with re~pect to proper location of the needle 11 within the vein of the patient.
The catheter 15 with its stylet therein is now pushed downwardly from the catheter guide tube 14 into the lower end portion of the straight hollow needle 11 and is con-tinued therefrom into the patient's subclavian vein 16 to a ~elected distance therein a3 determined by the surgeon. The stylet is now removed from the catheter providing a clear passageway through the catheter 15. Suitable connectors 17 are employed aq required to close or open the catheter passage when and as required.
The straight hollow needle 11 i9 now gently removed from the patient's vein 1~ by ~liding it out Or the vein, leaving ~:
the relatively soft plastic catheter 15 disposed in the vein through which blood or medicants may be provided to the patient ~:
as required by the use of conventional intravenous (I-V~ means : :
The preferred subclavian device 1~ of the invention is made sterile by employing convsntional means, and is made ready for use with the needle 11 thereof removably connected at its upper end to the lower stem 130 Or the syringe 13.

It is important that, during the carryin~ out of the foregoing procedures or other procedures that may be substi-tuted therefor, at no time should the lumen Or the catheter or needle be exposed to ambient air. Also, during the insertion or removal of a stylet into or out o~ a catheter 15, and during the use or the removal of oonnectors or caps 12, 17, 170 and 171 is being accomplished, such items should be closed by use of a temporary cover-up thereover as may be required to prevent the intake of ambient air into the system.
Although but a single embodiment of the subclavian vena puncture device of the instant invention has been disclosed and claimed herein, it is obvious that many changes may be made in size, ~hape, arrangement and detail of the several elements thereof, all without depart~ng from the spirit and scope of the invention as defined by the appended claim.
