- Sheets-Sheet 2 .1 SEPARABLE CATHETER INSERTION DEVICE BACKGROUND OF THE INVENTION
- This invention relates to medical devices for subcutaneous introduction of fluids into a patient, and more specifically to a catheter and insertion device therefor. These devices are generally used for intravenous infusion, however, they also can be used for infusion or withdrawal of fluids into or from other regions of the body. Hereafter, for purposes of simplicity, the devices will be referred to in relation to intravenous infusion.
- Catheters of the general type disclosed herein are available commercially and have been disclosed in the prior art. For example, self-contained catheters and insertion devices therefor are disclosed in U.S. Pat. Nos. 3,000,380; 3,010,453; 3,017,884, and 3,055,361. This general type of catheter was developed for usage where administration of fluids to a patient had to be either continuous or where such administration was intermit tent over a prolonged period.
- intravenous or other infusion of fluid into a patient was accomplished by means of a sterile needle.
- This needle was utilized to puncture the skin and vein of a patient.
- the needle was then taped to the surface of the skin.
- a conduit coupled to a source of intravenous fluid for example, a syringe or gravity bottle type infusion fluid source, was then connected to the needle.
- a source of intravenous fluid for example, a syringe or gravity bottle type infusion fluid source
- the prior art flexible catheters for infusion of fluids into the veins of patients generally include a hollow needle and a fairly long flexible hollow cannula, the catheter.
- One end of the catheter usually has'a coupling means or mechanism thereon, for example of the: luer type, for connection to a source of infusion liquid.
- the other end of the catheter is slidably disposed within the bore of the hollow needle.
- the hollow needle is then inserted into a vein of a patient.
- the catheter is pushed through the hollow portion of the needle into the vein.
- the needle is then removed leaving the catheter protruding from the body of the patient.
- the needle, catheter and coupling means can be completely enclosed in a sterile package which is unopened until the time it is to be used with a patient.
- the materials utilized can be sufficiently economic to render such devices disposable after use.
- the chances of contamination or the spreading of infection is substantially lessened compared to the reusable type injection devices which must be resterilized after every 4 of larger diameter than the needle bore, as above explained. Since the needle cannot be removed, it is continuously present on the catheter outside the patients body. In the past, the presence of the needle has been troublesome due to its bulkiness and to the fact that the patients skin can easily be accidentally punctured by the needle point.
- a sleeve which is slidably inserted around the needle prior to its insertion into the patients arm is disclosed.
- the sleeve is positioned on the portion of the needle which remains exterior to the patients body. After the catheter has been inserted and the needle withdrawn from the patient, the sleeve is moved toward the pointed end of the needle to cover it. Frictional contact between the portion of the sleeve not extending beyond the pointed end of the needle retains the sleeve on the needle.
- the pressure member of the device disclosed in the above-mentioned patent must also be held down with one finger of the hand inserting the catheter insertion needle into a patient in order to seize thecatheter. It is important that the pressure member seize or contact the catheter I to prevent the catheter from sliding longitudinally backwardly in the needle while it is being inserted. It is most desirable to maintain the forward end of the catheter near the pointed tip of the insertion needle while the two are being initially inserted into a patients .body
- the present invention therefore, solves the foregoing problems while incorporating .the' desirable attributes of a disposable catheter insertion device.
- the subcutaneous catheter insertion device of the presentinvention comprises.
- a needle having a longitudinal bore therethrough, one end of said needle adapted to facilitate puncture of and insertion into subcutaneous tissue, said needle having a longitudinal slot extending the length thereof, a hub member secured to the distal end of the needle having a longitudinal slot therein, a flexible catheter having one end slidably disposed in the bore of the needle and extending rearwardly therefrom, a coupling member connected operatively to the hub member, and means associated with the coupling member and movable to coact with a portion of Y the catheter between a first position and a second position, the means in the first position preventing longitudinal movement of the catheter in the needle.
- the means can be removably associated with the hub member and longitudinally movable between a first and a second position, the means in the first position preventing longitudinal movement of the catheter in the needle.

- Hollow needle 10 preferably made of a surgical steel, has one end which is cut at a taper to form a point 12. The otherend of the needle is secured in a hub member 14. Both needle 10 and hub member 14 contain longitudinal slots (better seen in later figures).
- a coupling sleeve 16 is arrangedfor sliding and removable attachment to a rearward projection 18 on the hub member 14.
- a clip member 20 is positioned in a channel formed when the-coupling sleeve 16 is slidably disposed upon the rearward projection 18.
- the hub member'l4 is also provided with a circular portion 22 of reduced diameter onto which a needlepolytetrafluoroethylene, or other suitable material.
- catheter extends through the hub member 14 and along a trough (better seen in later figures) contained in the rearward projection 18. It extends through the coupling sleeve 16 and terminates at its distal end in a suitable fitting 28, for example a luer female fitting.
- a luer plug 30 is provided for sealingly closing the open end of the fitting 28. The plug 30 is provided to prevent egress of body fluids from the catheter when it is being inserted and also when the catheter is not attached to a fluid infusion device.
- the needle cover 24 is shown secured 'onto the reduced diameter portion 22 of the hub member 14.
- plug 30 is disposed in the luer fitting 28.
- the coupling sleeve 16 has sealed around its distal cir cumference a flexible, preferably transparent sac 32 sealed at its distal end 34.
- One function of the coupling sleeve 16 is to maintain the sac 32 around the catheter 26, the luer fitting 28 and plug 30 to provide a sterile environment.
- the coupling sleeve 16 serves to retain the clip member 20 in contact with the catheter 26, as will be better seen later.
- the hub member 14, including its rearward projection 18, needle cover 24, coupling sleeve 16, and clip member 20 are preferably molded from synthetic polymeric materials such as polyethylene, polytetrafluoroethylene, polyamides, or some other material which is capable of being molded.
- the flexible sac 32 manufactured from, for example polyurethane, polyethylene or polyester film, can be attached to the coupling sleeve 16 by heat sealing or can be merely taped about the sleeve member utilizing a thin strip of adhesively backed tape.
- the interior and exterior of the needle 10, the interior of cover 24, the catheter 26, luer fitting 28, and plug 30 as well as the entire interior of the flexible sac 32 are sterilized during manufacture of the catheter device.
- the interior of the coupling sleeve 16 is also sterilized as well as the interior portion of the clip member 20.
- the needle has formed therein a longitudinal slot 54.
- the needle cover 24 is secured upon the reduced diameter portion 22 of the hub 14.
- the clip member is slidably disposed in a channel 40 formed by the rearward projection 18 of the hub member 14 and coupling sleeve 16.
- the clip 20 is composed of a bottom portion 42 of sufi'rcient vertical height so as to intimately contact the upper interior wall of the coupling sleeve 16 and also to press the catheter 26 against the upper interior surface of the rearward projection 18 of the hub member 14. This coaction of the lower portion 42 of the clip member 20 operates to prevent longitudinal movement of the catheter 26 as it is introduced into a patient.
- a second portion 44 of the clip member 20 extends upwardly through a longitudinal slot 46 in the coupling sleeve 16.
- the portion 44 of the clip 20 terminates above the coupling sleeve 16 in a finger or thumb grip 48 containing serrations or ridges on the top thereof.
- FIG. 4 is a full transverse cross-sectional view taken along a line similar to line 4-4 of FIG. 3, which better illustrates the operation of the clip 20 in relation to the catheter 26.
- the rearward projection 18 of the needle hub 14 contains a trough or channel 50 generally of semi-circular cross section extending the full length of the projection 18.
- the catheter 26 rides therein.
- the upper surface of the bottom portion 42 of clip 20 contacts the upper interior wall of coupling sleeve 16. As it does so, it is forced down upon the top surface of the catheter 26 so as to deform the catheter, thus frictionally engaging the catheter between the bottom surface of the bottom portion 42 of the clip member 20 and the walls of the channel 50 in the projection 18.
- the frictional engagement between the channel 50 and the bottom portion 42 prevents longitudinal movement of the catheter 26 as it is inserted into a patient.
- the construction of the hub member 14 and the re arward projection 18 integrally a part thereof as well as the channel is better understood by reference to FIG. 5.
- the needle is shown secured in the hub member 14, preferably integrally molded therewith.
- the longitudinal slot 52 in the hub member 14 and the longitudinal slot 54in the needle 10 are provided so that after the catheter has been inserted into a patient and the needle removed leaving the catheter in the patient, the catheter can be separated from the needle and hub member as shown in conjunction with FIG. 1 l.
- a wire stylet 58 as illustrated in FIG. 3 can be attached to the luer plug 30.
- the stylet extends from the plug 30 to ordinarily within a half inch from the end of the catheter as shown.
- the stylet lends rigidity to the catheter for easier insertion into a patient.
- the interior opening through the coupling sleeve 16 is of sufiicient diarnetral size such that the luer fitting 28 and plug 30 can pass through the sleeve 16 so that the sleeve and sac 32 can be completely removed from the assembly.
- the upwardly extending walls 60 shown both in FIGS. 3 and 5 are provided so that the coupling sleeve 16 will have additional surface area on the rearward projection to contact so that it will be held sufficiently tight merely by frictional contact.
- the distance between the interior sides of the upwardly extending walls 60 must be sufficiently wide to allow free passage of the bottom portion 42 of the clip member 20 therebetween.
- FIGS. 6, 7, and 8 present top, front and side views, respectively, of the clip member 20.
- the clip member is generally T-shaped and includes a lower portion 42 which is slidably disposed in the channel formed by the coupling sleeve and the rearward projection on the hub member.
- the middle portion 44 extends upwardly through the slot 52 in the coupling sleeve and terminates in the thumb grip 48.
- Thumb grip 48 has the ridges 56 for increasing a frictional grip between the thumb and the clip member.
- the needle cover 24 is first The catheter 26 is thus released from the grasp of the lower portion 42 of the clip member so that is is freely and slidably disposed within the coupling sleeve, hub
- the needle is removed from the patients-body leaving the catheter in place in the vein. Thereafter, the coupling sleeve 16 is removed from the rearward projection 18 of the. hub member 14. It is also removed completely over the luer fitting and plug attached to the distal end of the catheter. The coupling member, sac and clip member 20 then can be discarded.
- the catheter can be separated from the needle and hub member by' pulling the catheter through the slot 54 in the needle 10 and through the slot 52 in the hub member 14 as shown in FIG. 11;
- the luer fitting 28 can be attached to an infusion source such as the intravenous bottle 74 shown in FIG. 12 at any time after the sac is removed.
- the catheter is made from a sufficiently flexible material to allow radial deformation thereof as his removed through the slot 54.
- Such materials include polyurethane and polytetrafluoroethylene as mentioned above.
- the slot 54 in the needle is preferably of a slightlysmaller width than the diameter of the catheter 26' so that it must necessarily be deformed in order to be removed. This size relationship of the catheter and slot is important since it will cause the catheter to be retained inthe needle at all times untilit is forceably removed.
- the width of the slot 52 in the hub member. 14 is generally of slightly greater width than the catheter 26 so that removal therefrom can be accomplished with ease.
- FIGS. 13 and 14 An alternative embodiment of the present invention isshown in FIGS. 13 and 14.
- the hub member, rearward projection and coupling sleeve are combined into one assembly, generally designated 80.
