Definitions
- This invention relates to apparatus for intravenous insertion of a catheter.
- a catheter is an elongated, resilient, small-diameter tube normally inserted into a vein of a patient for the introduction or withdrawal of fluid.
- the catheter is normally left in position for at least several hours. It should be inserted safely and in a way to cause minimum discomfort to the patient.
- a cannula or hollow needle such as a hypodermic needle made of stainless steel, is disposed within the catheter to provide a sharp point projecting slightly beyond the end of the catheter to be inserted into the vein of the patient.
- the sha ⁇ point of the needle penetrates the skin and vein of the patient with minimum injury and discomfort, and guides the catheter into the vein. Once the catheter is in position, the needle is withdrawn and discarded.
- Accidental scratching or sticking personnel with a used needle can present a serious health hazard, including the possibility of transmitting infectious diseases, such as hepatitis, AIDS, herpes, and the like, from a contaminated used needle.
- the patented devices have various disadvantages. They have a complicated structure, are not easily operated with one hand, do not provide positive prevention of incorrect use, require operation in a manner which increases the risk of accidentally driving the canula entirely through a vein, or do not provide permanent shielding of the used needle.
- This invention provides intravenous catheter insertion apparatus which is simple, inexpensive, easy to make, easy to operate with one hand, and which minimizes the risk of driving the cannula entirely through a vein. Moreover, after the hypodermic needle has been used to insert the catheter, the needle can be positively and permanently enclosed in a housing with one hand and without being exposed so that it cannot be reused or accidentally stick someone. One-handed operation of the apparatus of this invention is important because it leaves the other hand free to stabilize the position of the inserted catheter as the needle is withdrawn to the enclosed position without ever exposing the sha ⁇ point of the used needle.
- the apparatus of this invention includes a cannula carrier disposed in an elongated housing having a front and a rear end.
- the carrier is movable by operation with only one hand from a first to a second position by an actuator which extends from the carrier through a longimdinally extending slot in the wall of the housing.
- An elongated cannula (hypodermic needle) is secured at one end to the carrier and extends longimdinally through an opening in the front end of the housing so the other (sha ⁇ ) end of the needle extends from the housing when the carrier is in the first position.
- the needle is adapted to support a cannula, which fits over the needle.
- the actuator permits one-handed operation to move the carrier from the first to the second position to retract the needle into the housing until the sha ⁇ end of the needle is shielded within the housing.
- Releasable locking means on the acmator and in the slot permit the carrier to be releasably locked in the first position.
- Permanent locking means on the carrier and on the housing adjacent the second position permit the carrier to be permanently locked in the second position with the needle fully retracted into the housing.
- the term "permanent locking means" indicates an arrangement in which the carrier cannot be moved relative to the housing without breaking the apparams, or using a special tool.
- the permanent locking means includes a locking stud on the rear end of the carrier which fits into a forwardly opening socket on an end cap mounted in the rear end of the housing.
- the acmator preferably includes a front shank mounted on the carrier to extend outwardly away from the central longimdinal axis of the housing.
- the front end of a longimdinally extending cantilever arm is secured to the outer end of the front shank.
- the rear end of the arm is secured to a transverse locking block which is connected to the inner end of an outwardly extending shank which passes through the longimdinal slot in the housing wall.
- the forward end of the longimdinal slot includes a transverse notch, which receives the transverse block, which is wider than the transverse width of the longimdinal slot.
- the two shanks and cantilever arm are somewhat flexible, and, with the block, are molded from plastic as an integral unit with the needle carrier.
- the cantilever arm acts as a leaf spring which urges the block to move outwardly so that when the carrier is moved to the first position, the transverse block snaps outwardly into the transverse notch at the forward end of the longimdinal slot in the housing wall to lock the carrier in the first or forward position.
- a releasable lock is formed between the locking block and the forward end of the longimdinal slot in the housing.
- the releasable lock is released by pushing the rear shank inwardly toward the center of the housing to cause the transverse block to move inwardly and out of the transverse notch so that the outer face of the transverse block can slide along the inner face of the housing wall, and permit the rear shank to travel through the longimdinal slot of the housing and move the carrier to the rear or second position to engage the permanent locking means.
- the permanent locking means includes a rearwardly extending locking smd on the rear face of the carrier. The smd snaps into an outwardly and forwardly diverging socket on an end cap mounted in the rear end of the housing.
- the socket is formed of several longimdinally extending fmgers anchored at their respective rear ends to the end cap.
- Each finger includes a surface spaced from the longimdinal axis of the housing, and which slopes outwardly in a forward direction.
- Each finger includes a rearwardly facing shoulder pe ⁇ endicular to the longimdinal axis of the housing.
- Each shoulder engages a matching surface at the forward end of a rearwardly and inwardly tapering section on the rear end of the locking smd.
- the tapered portion of the carrier smd enters the outwardly and forwardly diverging socket formed by the fingers, spreads the fingers apart, and permits them to snap toward each other in front of the transverse annular shoulder formed on the carrier smd.
- the smd is now permanently locked in the socket, and cannot be removed without rupturing the material used to make the smd on the fingers, or using a special tool.
- FIG. 1 is a longimdinal sectional view of the apparams with the carrier releasably locked in the forward or first position so the needle extends outwardly from the front end of the housing;
- FIG. 2 is a longimdinal sectional view of the housing before any assembly of the apparams;
- FIG. 3 is a top view of the needle carrier and needle before assembly within the housing
- FIG. 4 is a view taken on line 4-4 of FIG. 3;
- FIG. 5 is a view taken on line 5-5 of FIG. 4;
- FIG. 6 is a longimdinal sectional view of the end cap before assembly in the rear end of the housing.
- a cannula (hypodermic needle) 10 is secured at one end in a small bore 11 connecting with the interior of a hollow, generally cylindrical needle carrier 12 (FIGS. 1 and 5), which makes a sliding fit inside an elongated cylindrical and hollow housing 13, which has a cylindrical wall 14, a front (left as viewed in the drawing) end 15, and a rear (right as viewed in the drawing) end 16.
- the front end of the needle carrier includes a tapered Luer nozzle 17 shaped to make a snug fiction fit inside a conventional female Luer-Lock fitting 18 (FIG. 1) formed in a catheter hub 20, which carries a catheter 22 adapted to make a close sliding fit over the needle 10, which has a sha ⁇ end 23 projecting slightly beyond the left end of the catheter.
- the needle is secured in the small bore 11 by any suitable means, such as glue, spin- welding, or the like.
- the needle carrier includes an elongated cylindrical large bore 21 which communicates with the right open end of the needle.
- the large bore 21 serves as a flash chamber to receive blood once the tip of the needle enters a patient's vein.
- the housing and needle carrier are each made of a clear moldable plastic, such as polytetrafluoride, polyethylene, polypropylene, polystyrene, polycarbonate, and the like, to make it possible for the nurse to see "flash back" of blood entering the flash back chamber.
- a conventional filter venting plug 24 sealed in the rear open end of the needle carrier is permeable to air to allow flash back, but prevents blood from entering the interior of the housing 13.
- An elongated needle cover 26 makes a snap fit on the forward end of the housing 13 to cover the catheter and needle, the forward end of which projects slightly beyond the forward end of the catheter.
- the forward end of the needle is in the shape of a scarf or sha ⁇ point.
- the rear end of the needle cover includes an inwardly extending annular boss 27, which makes a releasable snap fit in an annular groove 28 (FIG. 2) around the exterior surface of the forward end of the housing.
- the cover is made of plastic, and has a wall sufficiently thin that it can easily be deformed to snap into and out of releasable locking engagement with the forward end of the housing.
- An acmator 29 on the needle carrier includes a square (as viewed in FIG. 3) thumb tab 30 formed integrally with the outer end of a transverse rear shank 32, the inner end of which is secured to a transverse rectangular locking block 34 on the rear end of an elongated, longimdinal cantilever arm 36, the forward end of which is formed integrally with the outer end of transverse front shank 37 formed integrally at its inner end with the exterior of the needle carrier, which is of circular cross section (FIG. 5) of slightly smaller diameter than the housing interior diameter.
- a pair of longimdinally spaced and outwardly extending annular guides 38 formed integrally with the carrier make a close sliding fit in the housing to maintain coaxial alignment of the carrier in the housing.
- the transverse dimension of the locking block 34 and cantilever arm 36 is slightly greater than that of the rear shank 32, which extends from the interior of the housing 13 through an elongated and longimdinally extending slot 39 in the housing wall 14.
- the cantilever acts as a spring, and normally is parallel to the longimdinal axis of the housing, as shown in FIG. 1.
- the apparams is easily assembled to the position shown in FIG. 1 by inserting the needle and needle carrier into the rear (end) of the housing.
- the longimdinal axis of the needle carrier is positioned co-linearly with the central longimdinal axis 40 (FIGS. 1 & 2) of the housing, and the needle carrier is oriented so that the radially extending rear shank 32 on the needle carrier is aligned with the slot 39 in the housing wall.
- the transverse dimension of the rear shank is slightly less than that of the slot.
- the transverse dimension of the block 34 is slightly greater than that of the slot.
- the thumb tab 30 is depressed slightly to deflect the rear end of the cantilever arm inwardly so that the upper surface of the block is just inside the inner surface of the housing to permit the needle carrier to be pushed forward into the housing interior by the application of longimdinal force to the needle carrier or thumb tab 30.
- the needle carrier moves forward (with the rear shank 32 sliding in slot 39 until the rear end of the cantilever arm 34 reaches a transverse notch 41 (FIG. 2) at the forward end of slot 39.
- the notch is slightly wider than the transverse dimension of the block on the rear end of the cantilever arm, and has a longimdinal dimension slightly greater than that of the locking block, which permits the rear end of the arm to snap outwardly and move the block into the notch 41.
- the block releasably locks the needle carrier against longimdinal movement within the housing unless the thumb tab 30 is depressed to move the block inwardly and out of the notch.
- the carrier can then be moved toward the rear end of the housing.
- the outwardly extending circular guides 38 on the exterior of the needle carrier provide clearance for the cantilever arm to deflect at its rear end to a location within the housing wall and thus clear the block from the notch 41 and place the outer surface of the block within the inner surface of the housing wall.
- an end cap 42 (FIGS. 1 and 6) is sonically welded inside the rear end of the housing.
- the end cap is made of a suitable plastic which permits sonic welding of it to the housing.
- the end cap includes a longimdinally extending sleeve 44 which makes a snug coaxial fit within the rear end of the housing, and which curves slightly inwardly in a forward direction.
- An outwardly extending annular flange 46 formed on the rear end of the sleeve has a forward face 48 welded to the rear end of the housing.
- a radially and longimdinally extending spacer 50 formed integrally with the sleeve and forward face of the flange makes a snug fit within the housing slot, and is also welded to the housing. The spacer helps maintain the uniform width of the slot in the housing to facilitate sliding the carrier as described below.
- Each fmger includes a short longimdinal section 58 at the inner end of a respective ramp 57. The sections 58 are equally spaced around the longimdinal axis 40 of the housing.
- a separate radially extending locking section 59 which is pe ⁇ endicular to the longimdinal axis of the housing, is formed at its inner edge with the rear edge of a respective straight section 48 and terminates at its respective outer surface with the interior surface of the sleeve to form a separate locking tooth on each finger.
- the four fingers form a forwardly opening socket 60 with a forwardly diverging annular surface defined by the inner faces of the forward ends of the fingers.
- the rear end of the needle carrier includes a longimdinally extending barb-shaped locking smd 62 which has a frusto conical nose surface 64 which converges inwardly toward the rear end of the housing to facilitate penetration of the locking socket by the locking smd.
- An annular outwardly opening groove 64 in the locking smd a short distance forward of the rear end of the smd forms an annular and forwardly facing locking surface 66 which is pe ⁇ endicular to the longimdinal axis of the housing.
- the locking smd drives into the locking socket.
- the frusto conical surface 62 of the locking smd engages the matching interrupted frusto conical surface of the socket, and spreads the fingers 44 outwardly so the ramps of the fingers ride up over the surface, and permit each locking section 59 on a respective finger to drop into the annular notch 64 on the locking smd to permanently lock the needle carrier in the second or rear position where the carrier cannot be moved without rupturing the material which forms the permanent lock, or without use of a special tool (not shown) which can be inserted into the rear end of the socket to spread the fingers apart and permit the carrier to be released.
- the various parts of the apparams can be made from the same or different kinds of molded plastics, as long as the cantilever arm on the carrier has suitable strength and resilience to act as a leaf spring and urge the locking block outwardly away from the longimdinal axis of the housing.
- the end cap and housing materials should be compatible for acoustic welding.
- the device is assembled as shown in FIG. 1, it is then packaged and terminally sterilized.
- the nurse opens the package, prepares the patient's venipuncture site, removes needle cover 26, makes the venipuncture, and observes the blood flash back into the needle carrier 12. Holding the housing with one hand, the nurse advances the catheter and needle into the vein, having first slightly manipulated the catheter hub on the carrier nose to be sure that the two elements will separate easily. This manipulation is done carefully to prevent moving the catheter longimdinally far enough to extend beyond the sha ⁇ point of the needle. Otherwise, there is the danger of damaging the catheter by thereafter trying to re-expose the sha ⁇ end of the needle. Such damage could provide a site for formation of blood clots, which could be life threatening to the patient.
- the nurse uses one hand to hold the catheter in that position, and with the other hand holding the housing, retracts the needle into the housing by pushing down on the thumb tab 30 to release the forward lock and thereafter sliding the thumb tab and needle carrier to the rear of the housing to drive the locking smd into the locking socket.
- This locks the needle carrier in the permanent locking position at the rear of the housing, which is sufficiently long to enclose the sha ⁇ end of the needle.
- the housing acts as a "Sha ⁇ S box" for the potentially dangerous needle, which is now no longer exposed.
- the apparams just described is easily operated with one hand by either holding the housing between the thumb and the middle finger and using the index finger to retract the tab, or the housing can be held in the palm of the hand with four fingers, and the tab retracted by sliding it back with the thumb. In either case, the other hand is free to hold the catheter in place in the patient's vein as the needle is retracted and permanently stored in the housing.
- the releasable lock for the needle carrier and the housing in the first position at the front of the housing is easily released by simply applying a slight radial and inward force on the tab, which unlocks the carrier from the housing without requiring any longimdinal force on the apparams.
- the carrier smd engages the socket, and requires longimdinal force to permanently lock the carrier to the housing end cap, the sha ⁇ end of the needle is safely within the housing.
