SECURING DEVICE FOR CATHETER PLAOEMENT ASSEMBLY
This invention relates to a clevice for securing a catheter placemen~ assembly in position on the arm of a wearer.
In the past, th~re have been n~nerous types of catheter placement devices wherein a needle which is sheathed in a relatively ~lexible slee~e is inserted into the vein and, thereafter, the needle is xemoved. In other instances, a needle is inserted directly into the vein. In any event; it is often necessary, particularly where intravenous feeding is involved, to secure ~le asse~ly to the arm of a wearer for extended periods o~ time. In the past, the unit has been taped in a relatively difficult operation to the a~,l. This invention is o an improved device which is adapted to be positioned over the catheter placement assembly, once it has ~ been inserted, and which facglitates securing the assembly to ; the arrn.
; It isr accordingly, an obiect of this invention to provide an inexpensive unit which is well adapted for securin~ a catheter placement assembly, such as the type used in intravenous ~eeding, to the arm of a wearer, and which can be easily removed and which can be dxessed easily and which protects the puncture - point ~rom infection.
In accordance with this general ohject, the instant invention will now be described with reference to the accompany-ing drawings wherein a unit of the device to size has been ~3378~
illustrated.
Figure 1 is a plan view of the securing devioe illustrat-ing its use;
Figure 2 is a perspective view of the securing device;
Figure 3 is a view in cross section taken along the plane indicated by the line 3-3 of Figure 1 and looking in the direction of the arrows;
Figure 4 is a bottcm plan view of the device.
lt will be helpful to the reader in understanding the use of the instant invention to refer to the applicants Canadian Patents 1071491 and 1083456 of a Catheter Placement Assembly. Al-though not exclusively for use with such a specific catheter place-ment assembly, the instant invention will be understood on refar-ence to that application. Referring now to the drawings, it is se~n in Figures 1 and 2 that the securing device is ganerally de-signated by the numeral 10, and that it is in~ended to be posi-tioned over the ears 16 and 18 of a catheter body for introduction of intravenous fluids as is generally indicated by the numeral 12, preferably, after the ~eedle 22 has been withdrawn axially frcm the flexible cathe~er 20. A suitable fiiting 24 is provided, and this fitting is connected to a tube 26 which in turn is used for intro-ducing intravenous feeding. The securing device 10 comprises a pair of wings 28 and 30, each composed in the preerred emtodinent of diverging portions 32 and 34 and 32' and 34'. The wings are joined by a body 35 with side walls 38, 40 and 42 extending upwardly of the upper surface of the wings and in the side walls of ~<
~33~
which tnere is an a~ial cut-out, as at 36 defined in the walls ~14 and 46, with the space between the walls at the CUt-QUt being sized for passage of the catheter body and snug receipt ~hereof. As is seen in Fic~ure 4, the ~mderside of the ears ~8 and 50 are received wit'nin a cavity in the body ~ith the dome 52 comprising a ~roove in ~he roof to nestle about the body~
In use/ once tne needle and catheter have been inserted into the vein, it is adapted to be firmly secured in position on the arr,l by applying ~he securing device of the instant invention over the ears 16 and 18, and, thereafter, the unit may be taped down conveniently by the tape T indicated by the dotted lines in Figure l. In the preferred er~odiment, the unit is made of molded polyethylene, and the unit is somewhat bendable alony the centerline oE the unit 52 which acco~nodates application of the unit in a general snap-like manner preferably.
It is, therefore, easy to apply and is well adapted for holding the catheter placement assembly in posîtion.
With respect to the catheter placement assembly in bd~/~o 0~7~nt~
*~s~ 6~ 7~which has relatively small ears on the body, this device can he taped directly to the skin o a wearer;
however, it is yenerally di~ficult ~o do and requires a skilled technician using a sling type bandage. Many placement assemb-lies do not have ears at all. Various types of methods are used to tape tnem into position; however, because the unit must be Manipulated for the main purpose, namely, to insert them into ;~ .
~L~3378~
a vein, protrudiny devices are generall~ avoided. This invention, it is seen is of a device which can ~e readily positioned over a cathe~er placemen~ assembl~, after it is in place, which hy Illeans of the dome or roof, captivates it in position with the outwardly-extendincJ wings resting on the arm o~ a pa~ient whereupon ~hey may be taped readily in the position desired with the tape being away rom ~he axial cen-~erline o~
the device and~ hence, ~he puncture site. The clevic~, once in position, cannot readily rotate o.r move axially, which is a sa~ety feature, since ~he devices are o~ten installed over long periods of time as an intravenous feediny. Motwithstandiny this, the securiny device may be readily removed simply by holding- it in position in the central zone while the tape is removed from ~he winy zones. Moreover, the catheter placement assen~ly is positLoned and held firmly without direct contact of the ca~heter placemerlt asser~ly itself so that the sar..~e can be manipulated, as when chanying the material introduced into the patient. Finally~ the puncture site is not covered by tape. An ointment can be used and a bandaid directly at the puncture site without inter~erence frorn the tape securing the catheter placernent assembl~. All of the foregoincJ are advantages and objec~s of the instant invention.
In the prefexred er~odiri~ent, the axial distance between the tips of the diverging portions o~ the wi.ngs 3~ and 34 are about one and one-quarter inches, while the thickness of them is about .020 inch, and the distance between the portiorls o the wings 32 and 32' is about one and o.ne-quarter inches. The ~378~
height of the dom~ or body is of z height to accol~nodate nestliny over th~ particular catheter placement assembly which is utilized and a cavity is provided in it, as indicated, ~Jhich is sized to nestle yieldably over the c~theter placement asse~l~ly with the plane oE encJayement of the wing arld the lower portion o the catheter placement assembly beincJ a~ about a co~non level as indicated in Figure 3. In other words, the - -cavity conforrns to the shape of the particular catheter placement assembly to which the securing device is installed and for installation it may be hingedly opened about the line of syn~etry to be restored by the plastic memory to its no~nal position as shuwn in Figures 1, 3 and 4, definincJ what may be described as a yieldable clamp type action about the hinc~e joint composed of the roof or bridcJe ]oininq the winys in which the cavi~y is located.
