LOCKING GUIDE N A S`YRINGE NEEDLE Filed June 25, 1941 ATTORNEY INVENTOR. l
Patented Jan. 11, 1944 UNITED STATES PATENT OFFICE LOCKING GUIDE N SYRINGE` NEEDLES F. Vincent Burke, Brooklyn, N. Y.
Application June 25, 1941, Serial No. 399,603
The invention relates to the ordinary syringe and needle combination which is used for injection or aspiration. The two way stop-cock is attached to the syringe and needle, said stop-cock is used to change the direction of the aspirated fluid which ows through the tube into a receiving vessel.
My locking guide is placed on the usual short bevel needle which is attached to the syringe. The needle is inserted through the chest wall between the ribs and set at a chosen point where pus or fluid is reached in the chest space. The guide is then immobilized by tightening the knurled nipple, thus holding the guide disk in a given position. This 1s applicable to the aspiration of pericardial eiusion as well as free iiuid or pus in the pleural space as well as in interlobar empyema.
It Will be convenient to use my invention on such parts of the body where injection or aspiration is necessary, apart from that area mentioned above.
The further purpose of my invention allows the maximum amount of withdrawal of the uid with a minimum of discomfort to the patient as well as a minimum trauma to the viscera.
With the above objects in View, the invention resides in the arrangement of the parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that slight changes in the embodiment of the invention may be made within the scope of what is claimed, without departing from the spirit of the invention.
Referring more specifically to the drawing:
Figure 1 is a side View showing my locking guide device in position on a portion of the chest with the needle inserted, xing the position oi the aspiration point.
Figure 2 is an exploded perspective view of. all parts of the locking guide.
Figure 3 is a section on the line 3 3 of Figure 1.
Figure 4 is a sectional view on line 4--4 of Fig-r ure 3, showing all parts with the needle inserted.
The numeral I is the entire locking guide; numeral 2 is the needle; numeral 3 is the two way stop-cock; numeral 4 is the usual syringe; nu-
(Cl. 12S-215) meral 5 is the end of the needle; numeral 6 is the chest wall; numeral I is the threaded expansion unit with the bevelled end I3; numeral 8 is the guide disk; numeral 9 is the collar; numeral I is the nut; numeral II is the nipple for hand turning by means of the knurled portion I I numeral I2v is the tapered end of the nipple through which the syringe needle is placed; numeral I3 is the bevelled hole in the guide disk plate 8 for insertion of the member l. The guide disk plate 3 rests smoothly against the body and I4 is the needle gripping end of the expansion unit 1. The tapered end I2 of the nipple causes gripping of the needle by the member l by reason of the threaded portion thereof going through the nut I0 and through the threaded portion of the knurled portion II' of the nipple.
The invention having been set forth, what I claim as new and useful is:
A locking guide on a syringe needle, comprising a guide disk with a hole therein, at least a portion of the wall defining said hole being bevelled, an expansion unit having at one end an enlarged portion with a bevelled surface complementary with said bevelled wall, a needlegripping-portion at the other end of said expansion unit, and a threaded portion intermediate the ends of the expansion unit, saidvexpansion unit passing through said hole with said bevelled surface thereof engaging said bevelled wall of the hole, so that the disk and enlarged portion of the expansion unit present a smooth external surface to the human body engageable by the needle, a collar mounted on said expansion unit in contact with said disk, a nut threadedly engaging said threaded portion of the expansion unit to clamp said disk, expansion unit and collar together in position, and a threaded nipple having knurled and tapered portions, said nipple being threadedly engaged on said expansion unit to clamp said gripping-portion thereof against the syringe needle passing through said expansion unit to secure the expansion unit, nut, collar and guide disk in a given position with respect to the end of the syringe needle.
