INTRAVENOUS CATHETER PLACEMENT UNIT WITH RETRACTABLE NEEDLE Filed Feb. ll, 1964 INVENTOR.
ffQy/Z Da/7a@ J L hws/, ff-9251017 ATTO E Yb United States Patent O INTRAVENOUS CATHETER PLACEMENT UNIT WITH RETRACTABLE NEEDLE Karl A. Pannier, Jr., and .lames L. Sorenson, Salt Lake City, Utah, assignors to Sorenson Research Corp., Salt Lake City, Utah, a corporation of Utah Filed Feb. 11, 1964, Ser. No. 344,100 8 Claims. (Cl. 12S- 214) This invention relates to improvements in a catheter placement unit with retractable needle, and more particularly to such a unit highly desirable for the placement of an intravenous catheter for parenteral infusions into the body by means of a catheter, although the invention may have other uses and purposes as will be .apparent to one skilled in the art.
Catheter placement units have now been developed which facilitates the positioning of a catheter in a vein or other part of a patients body by advancing the catheter through a cannulated needle already inserted in the body, while infusion is taking place. After the catheter is properly positioned it is necessary for the attending surgeon to withdraw the needle from the body of the patient, and since it cannot be removed entirely from the catheter already connected to the infusion system, something must be done to the needle to prevent it ultimately cutting the catheter or jabbing the flesh of the patient during subsequent movement of the patient while the catheter remains in place. Providing such protection against what might be termed a floating cannulated needle has proven irksome and at times quite difficult in the past. Frequently, Iadhesive tape has been utilized and wrapped around at least the pointed end of the needle and a par-t ofthe catheter when the catheter is anchored, also by adhesive tape, to the body of the patient. This procedure was tedious as well .as delicate, and the free needle limited the exposed length of the catheter with which the surgeon had to work.
With the foregoing in mind, it is an imporant object `of the instant invention to provide a catheter placement unit including a' cannulated needle through which the catheter is advanced, and which unit is so constructed that immediately upon withdrawal of the needle lafter advancement of the catheter, the needle is automatically sheathed completely within a part of the unit itself.
Another important object of this invention is the provision of a catheter placement unit including a cannulated needle through which a catheter is advanced while infusion takes place, the unit being so arranged that the needle may be withdrawn by manipulating a part of the unit and is immediately and completely sheathed Within a part of the unit, no further protection for the patient or the catheter from theneedle being necessary.
It is also an important feature of this invention to provide a catheter placement unit embodying a cannulated needle through which the catheter may be advanced, the unit being so constructed that the needle is withdrawn from the body of a patient directly into Iand cornpletely sheathed by a part of the unit, leaving an added length of catheter available for the surgeon to work upon.
Also a desideratum of this invention is the provision of a catheter placement unit having a cannulated needle retractable into a part of the unit, there being a catheter sheath temporarily bonded into the hub of the needle and by means of which the needle may be withdrawn from the body of a patient into retracted position, whereupon the catheter sheath breaks free from fthe needle and maybe discarded.
Still another feature of this invention resides in the provision of a catheter placement unit so constructed that as a cannulated needle embodied therein is withdrawn from the body of a patient it is sheathed in a 3,262,449 Patented July 26, 1966 ice portion of the unit, there being means holding the needle firmly for insertion into the body of a patient which are automatically released upon full advancement of the catheter through the needle.
Another object of the invention is the provision of a catheter placement unit so constructed that a cannulated needle may be inserted inthe body of a patient and Withdrawn therefrom in-to a completely sheathed location without contactof the surgeons hands upon the needle at any time.
While some of the more salient features, characteristics and advantages of the instan-t invention have been above pointed out, others will become apparent from the following disclosures, taken in conjunction with the `accompanying drawing, in which:
FIGURE 1 is an enlarged fragmentary central verti-v cal sectional view, parts being shown in elevation, of a catheter placement unit embodying principles of the instant invention, portions of the unit itself being exaggerated, and theunit being shown in position for but prior to use;
FIGURE 2 is a view similar in character to FIGURE l but showing the catheter fully advanced through the needle;
FIGURE 3 is a viewA similar in character to FIGURES 1 and 2 but illustrating the needle retracted after advancement of the catheter and the removal of the catheter sheath; and
FIGURE 4 is a greatly enlarged' transverse vertical sectional view taken substantially as indicated by the line IV-IV of FIGURE 1, looking in the direction of the arrows.
As shown on the drawings:
All parts of the instant invention, with the exception of the cannulated needle and a locking element which are both preferably metal, may satisfactorily be made -of a suitable moldable plastic material, the catheter and its sheath preferably being transparent, and where parts of the structure are initially in separate pieces for assembly advantages, the parts may be firmly united with the use of a suitable cement.
The illustrated embodiment of the instant invention includes a cannulated neede 1 having a flared outer end 2. Around the outer end of the needle and firmly secured thereto is a bushing or false hub 3, the com-plete structure of which is best seen in FIGURE 3. Adjacent the inner edge thereof, that end which is near the patients lbody when the device is in use, the bushing is provided with a radially extending flange 4 with an annular inwardly tapering wall 5 adjacent that flange. iOn the outer end thereof the bushing is reduced in diameter to form a cylindrical projection `6 for telescopic engagement with a catheter sheath 7.
The sheath 7 is preferably an extrusion of a non-wettable plastic material, polyethylene being one satisfactory substance, and is provided with a slit i8 extending longitudinally thereof along t-he top of the unit. The Asheath is extruded in such a manner that it 'has `an inherent resiliency 'wh-ich acts to lmaintain the slit 8 closed at all times, thereby rendering it unnecessary to use any added physical sealing means. Accordingly, .surface tension of any liquid, outside `or within the sheath, will prevent that liquid from tllowing through -t-he relatively firmly closed slit `8. The outer end of the sheath is preferably closed by a friction fitted cap 9 to preserve sterility of the contents of the sheath. The inner end of the sheath is telescoped over the extension 6 on the bushing G and at the annular region 10 the sheath is temporarily bonded to the bushing by means of a light cement or in an equivalentmanner. The sheath may lbe o-f any desired length,
Idepending upon the length of catheter desired, usually 6 or 9 inches.
A needle hub 11, which is grasped by the surgeon when the needle is inserted, generally cylindrical in shape encases the aforesaid lfalse hub or bushing 3, but in spaced relationship thereto. This hub 11 is provided 'with a nose 12 on the inner end thereof of reduced diameter which has an aperture 113 therein of sutiicient size for the needle to readily slide therethrough. vWith reference now to FIGURE l, it will -be seen that as the unit is originally assembled, the shoulder for the hushing 3 is seated .against the inner wall of the hub 11. yIt is held in that position `by a retainer 14 in the 'form of a thin metallic cylinder tixed inside the hub 11 `in any suitable manner. This retainer has a plurality of tangs 1S, there Ibeing three shown in the illustrated embodiment, bent inwardly and downwardly 'from the retainer cylinder 14 into end engagement with the ange 4 on the bushing 3 thereby holding the needle 1 suiiiciently iirmly for the surgeon to grasp the hub 11 and insert the needle in the fbody of a patient. Inside the outer end of the hub 11 and also inside the retainer 1i4 is a slidable sleeve 16 frictionally iitted over the shea-th 7 and a part of the hushin'g 3, which sleeve is frictionally maintained in position and which is used to release vthe tangs 15 from their engagement with the ange 4 in a manner that will later appear.
A catheter 17 extends through the sheath and enters the cannula of the needle 1, the outer end of the catheter 'being firmly anchored, cementitiously or equivalently, in cat-heter advancing means or an actuator 18. The actuator 118 has the external appearance of two cylinders, one upon the other, and the cat-heter terminates in the yupper cylinder, extending through the slit 8 in the catheter sheath 7 inwardly of a projection 19 also extending from `the 'upper portion of the actuator through the slit in t-he tube. This projection when the actuator is moved lalong the tube opens the tube at the slit and aids the advancement of the catheter, since the projection is slightly Wider than t'he diameter of the catheter. The outer end of the upper portion of 'the actuator terminates in a tu- Ibular extension -20 shaped in the iform of a Leur iittinig -for the reception oif the end of an in-fusion tube 21 which may be connected with any suitable tform of infusion apparatus or system. The lower portion of the actuator is in t-he `form of a tube 22 which encloses the catheter sheath 7 and on its inner end is reduced in diameter to form a projecting portion 23 which rat-her intimately iits the catheter sheath '7 and functions as a guide for the actuator, and which is also of approximately the same diameter as the aforesaid slidable sleeve 16 in the needle hub 11.
Initially, the catheter is, of course, provided with a guard for t'he needle which also keeps the needle sterile, and a sterile cap is placed over the Leur iitting 20, and the entire assembly may be encased in a plastic tilm sack.
"In use, the instant catheter placement unit is extremely easy to operate, quite effective, and the placement of the catheter may be accomplished with great rapidity and no mess. The outer sack and Leur iitting cap are removed, and the catheter is connected to the infusion system through the tube 21. The needle guard is removed, and the catheter unit is ushed ,with the infusion solution to remove any possible air and also any sterilization residue. The surgeon may then grasp the needle hub 11 and insert the needle in the Ibody of a patient. Then, it is a simple expedient to smoothly and easily advance the catheter, infusion having been started, hy holding the needle hub 11 in one hand, grasping the actuator 1'8 in the other 1hand and moving the actuator toward the needle hub into the position seen in IFIGURE 2. The catheter is then advanced fully into rthe patients body, and fit will be noted that the portion 23 upon the inner end of the actuator has contacted the movable sleeve 13 in the needle hub and iforced that sleeve toward the opposite end of the hub thereby elevating the prongs 15 to the position seen in IFIGURES 2 and `3 and releasing the needle bushing 3. This advancement of the catheter and the release of t-he needle bushing and the telescopic connection of the actuator with the needle hub may all be accomplished in one smooth movement. It is a simple expedient then to retain hold of the needle hub 11, and Agrasp the projecting end of the catheter sheath 7 and pull it outwardly thereby withdrawing the needle `from the patients body and sheathing it within the needle hub and the actuator as seen clearly in FIGURE 3. The temporary .bond at 10 between the catheter sheath and the bushing 3 is sufficient for that purpose, `but when the needle is fully sheathed and the parts are substantially in the position seen in FIGURE 3, the temporary bond -breaks loose and the catheter sheath is disposed of. The withdrawal of the needle and the `sheathing of it in the catheter hub and actuator and removal of t-he catheter sheath `is also one smooth simple operation. It will also 'be noted that the sheathing of the needle upon withdrawal leaves an added portion of catheter previously covered iby the needle available for the surgeon to work upon. Thus, it can be seen that with the instant invention, to completely, place a catheterand withdraw the needle requires only three simple movements of the part of the surgeon, namely (1) insertion of the needle; (2) placement of the catheter with automatic release of the nee- -dle bushing; and (3) withdrawal of the needle, sheathing of the needle and freeing the catheter sheath.
It will be understood that modification and variations may be eifected without departing Ifrom the scope of the novel concepts of the present invention.
