Definitions

  • the present invention relates to a therapeutic apparatus and has particular reference to devices adapted especially for the purpose of indefinite continuous introduc-v tion of fluids into the vascular system.
  • the device of the invention is intended mainly for use in connection with the introduction of fluids into the vascular system, it may obviously be used for other purposes, as for example, introduction of suitable sounds or catheters for examination of the interior of the heart.
  • plastic capillaries One recent proposal consists in a device wherein the capillary is introduced in such a manner that the vein is pierced by a metal canula having its tip or fore-end tapered and having an inside diameter of at least 2 mm.
  • the canula can contain in its bore a second canula having a smaller diameter.
  • the canula is introduced into the vein after which a fine plastic canula is introduced into the pierced blood vessel through the bore of the first canula, if desired, after removal of the second inner canula, and, finally, the outer metal canula is withdrawn over the plastic canula.
  • the plastic canula is provided at its outer end with a wing-shaped'metal canula adapted for being fastened to the skin or the plastic canula is otherwise fastened, and it is thereafter connected with an infusion liquid supply line.
  • Another prior proposal consists in a plastic canula assembly formed in such a manner that canula sections each having a length of about 60 mm. and formed from a hard plastic material, such as rigid P.V.C., are shrunk onto a metal canula having a smaller diameter and being tapered at its tip or fore end in the conventional manner.
  • the tapered or conical forward portion of the short plastic canula extends to the rear end of the beveling of the pointed end of the metal canula, whereby the pointed end of the metal canula gradually assumes the full crosssection of the plastic canula.
  • the plastic canula at its end opposite the pointed end is connected with a second metal canula having a somewhat larger cross-section, being mounted thereon by means of a piece of shrunken tubing also made of plastic and which covers the rear section (Rochester Plastic Needle).
  • a piece of shrunken tubing also made of plastic and which covers the rear section (Rochester Plastic Needle).
  • the sections being provided on a metal canula and introduced with the metal canula into the blood vessel when the vein is pierced. These sections remain in the puncture opening after the subsequent removal of the metal canula.
  • plastic canula sections are introduced through the bore of the metal canula and remain inserted in the blood vessel after the metal canula has been removed. In the latter device the injection passage produced by the metal canula has a greater diameter than the plastic canula and, consequently, there exists the danger of bleeding due to the fact that the size of the puncture necessary for the introduction of the apparatus is greater than that of the retained device.
  • An object of the present invention is to provide an apparatus by which all of the disadvantages referred to above are entirely obviated.
  • Another object of the present invention is to provide an apparatus which makes possible the installation of a plastic self-retaining canula into a vein for continuous infusion of fluid into the vascular system.
  • Another object of the invention is to provide a form of canula which, in addition to being an apparatus for introducing fluids into the vascular system, may also be used as a sheath for conducting a sound or catheter of proper form for the purpose of examining the interior of the heart.
  • Another object of the invention is to provide a form of canula having means forming a part thereof for holding the apparatus firmly in position in the vein, which has been punctured.
  • the therapeutic device of the invention is particularly suitable for continuous intravenous infusions and comprises an inner metal canula provided at the tip or foreend with a tapered portion, a plastic canula having a tapered tip or fore-end and a somewhat larger diameter adapted to receive and carry the metal canula designed so as to accurately fit the canula, and so as to tightly seal off the latter.
  • the tapered or conical portion of the plastic canula terminates at a point just short of the tapered section of the metal canula tip in such a manner as to provide a smooth fit with the metal canula and to avoid the formation of a perceptible shoulder, whereby the plastic canula can be introduced into the blood vessel in an easy sliding manner together with the inner metal canula.
  • a reinforcement formed integrally with the plastic canula proper, the reinforcement having on its free end a recess or opening adapted to receive a cone fitting, such as a Rekord cone and/or Luer cone.
  • reinforcement at the outermost end of the plastic canula is preferably conical and on its exterior may be provided with a holding plate.
  • An advantage of the invention resides in that the plastic canula is formed from a flexible physiologicallyacceptable plastic material which neither on sterilization nor on extended contact with blood plasma or other fluids becomes brittle or undergoes any other deformation changes.
  • a suitable material for the construction of a plastic canula Rigid polyvinylchloride has been found not to be particularly suitable other than for the reasons already mentioned. Polyvinylchloride, as many other plastic materials, often contains plasticizers which are extracted on contact with the blood plasma. The plasticizers, on the one hand, are not always physiologically acceptable and, on the other hand, the mechanical properties of the plastic material are often changed due to the extraction of the plasticizers therefrom so that deformation, embrittling, tearing, etc., occur.
  • polypropylene as well as a mixture of high-pressure and low-pressure polyethylenes, as for example in a ratio of 85%:l5%, is very satisfactory for forming the plastic canula.
  • a particularly suitable material is the product polypropylene KR1122 Badische Anilin- & Soda-Fabrik A.G., Ludwigshafen am Rhine, Germany.
  • the inside diameter of the plastic canula of the invention can be so dimensioned as to permit the passage therethrough of a plastic sound or catheter having a smaller diameter and a correspondingly greater length and into the blood vessel, and from there into the auricle. With the aid of such a sound it is possible to introduce fluids directly into the auricle, such introduction being possible during installation of the device for carrying out a continuous intravenous infusion, which infusion can be temporarily interrupted for this purpose Without any difficulty or need for the further installation of a second canula.
  • FIG. 1 is a longitudinal sectional view of a canula assembly according to the invention
  • FIG. 2 is a longitudinal sectional View of the plastic canula
  • FIG. 3 is a longitudinal sectional view of a plastic stopper provided with a rubber cover
  • the numeral 7 designates an inner metal canula and 1 an outer plastic canula which is adapted to fit accurately around the metal canula so as to tightly seal it off.
  • the plastic canula 1 is made of polypropylene.
  • the plastic canula 1 has, at its tip or fore-end a taper or conical portion 2 (tapering inwardly to diminish the usual thickness) which is attached to the inner metal canula 7 at the area of the inwardly tapered point 8 to produce a smooth fit with the metal canula, i.e., without a shoulder being formed.
  • the conical or tapered surface terminates just short of the end of the metal point.
  • an outwardly tapering portion forming an integral conical reinforcement.
  • the reinforcement 3 extends outwardly into a further expanded portion 4, the outer surface of which is preferably provided with grooves, serrations or otherwise roughened.
  • the reinforcement member 3 may be provided with a holding plate at the expanded portion 4 thereof.
  • the holding plate constitutes a means for securing the apparatus in fixed position until the infusion is completed.
  • a similar holding plate 11 may be provided for the metal canula.
  • the plastic canula 1 is also provided with a conical recess 6 adapted to receive the shoulder of a Rekord cone or a Luer cone.
  • the metal canula is preferably provided with a stylet which is advantageously a rod or spring wire which is of sufficient diameter so as to be rigid (not shown).
  • the inner metal canula is provided with a plastic member 9 the outer cone of which is seated in the conical recess 6.
  • the plastic stopper according to FIG. 3 comprises an outer cone 13 having a shoulder portion 12 and the rubber cover 14 with the reinforced portion 15.
  • the therapeutic apparatus of the invention is enclosed in a plastic bag and sterilized by means of gaseous ethylene oxide.
  • the cylindrical part of canula 1 and the plastic member 9 are protected by a tube provided with a cotton filter.
  • the protecting tube is removed from the cylindrical part.
  • the vein is then punctured with a light step.
  • the apparatus is carefully introduced into the vein. If the blood is leaking into the protecting tube of the plastic member 9 the metal canula is pulled out of the plastic canula which remains in the vein and at the same time the plastic canula is pushed further into the vein.
  • the outer cone of a dripping infusion or transfusion tube is then connected with the recess 6 of the plastic canula, the recess 6 being filled completely with blood.
  • the plastic canula can be closed by the sterile plastic stopper of FIG. 3 with the rubber cover. Injections can be made through the rubber and blood removed at any time.
  • the plastic canulae of the invention has the important advantage that the shoulder portion thereof prevents the canula from disengaging itself and from entering into the vascular system of the patient. Furthermore, the plastic canula is formed of a material not producing irritation on prolonged insertion and which, additionally, is entirely stable. Additionally, in accordance with the invention, the manufacture of the plastic canulae can be undertaken in an economically efficient manner. Due to the construction of the canula of the particular plastic, it can be maintained in position in the vein for long periods since, in contrast to the heretofore employed rigid metal canulae, it does not produce a mechanical irritation of the interior of the blood vessel. Additionally, there is the advantage that, when the canula is in place, the supply of the infusion liquid can be interrupted by detaching the supply line and the canula used for the introduction of a sound or catheter into the auricle. Alternatively, the
  • canula may be used for injection of other materials as,
  • the plastic canulae in accordance with the invention, are highly flexible, are capable of repeated sterilization treatments, and serve to handicap the patient only slightly.
  • a patient having such a canula inserted in an arm vein can, for example, eat and drink using the arm. This, in itself, represents a great advantage over the infusion canula heretofore available.
  • reinforcement 3 is formed integrally with canula 1 by injection molding, it is, of course also possible to produce these two portions 5 separately and to thereafter join them as by soldering, taking care only that the bond offers sufficient resistance. and security and will not become loosened, deformed or become embrittled in use or in sterilization.
  • a therapeutic device comprising an inner metal canula having a cutting edge at the forward end portion thereof, a flexible, substantially non-distensible canula formed of a physiologically acceptable polypropylene plastic material positioned about said metal canula coaxial with the same, the forward end of the plastic canula adjacent the insertion end of the metal canula tapering inwardly to substantially the same diameter as the metal canula in order to make a smooth, even, and edge-tight contact therewith and terminating just short of the forward end of said metal canula, said plastic canula defining, as integral parts thereof, a first portion of substantailly uniform outer cross-section and wall thickness extending rearwardly from said forward end, an outwardly tapering second portion of rearwardly increasing wall thickness, extending rearwardly from said first portion,
