Definitions

  • This invention provides a U-shaped intravenous needle structure including a rigid hollow needle, a curved rigid tube portion connected thereto and connecting means for connection to a source of intravenous fluid.
  • the U-shaped member permits the use of a direct. flexible tubing between the structure and the intravenous source, or bottle, thus reducing the danger of inadvertent lateral movement of the needle relative to the body.
  • Venous infusion is a conventional medical procedure wherein blood, medications or other desirable fluids, including nutriments, can be fed directly into the blood system of the patient being treated. It is extremely im portant that the infusion needle be held firmly and safely at a venipuncture site in the patients body, e.g. usually through the patients arm, or other extremity.
  • Conventional intravenous infusion procedures gener ally comprise performing a venipuncture in a patients, e.g., arm, utilizing a hollow needle to which an infusion tubing is attached. Commonly, the tubing attached to the needle must be flexed 180 to the direction of the I.V. bottle which is usually near the shoulder or head of the patient.
  • a curved, rigid, intravenous needle structure which can be readily connected to conventional infusion apparatus but which results in a needle which is not prone to lateral movements relative to the body member of a patient and which does not require the use of a rigid board member to restrain the patients body member, e.g. arm, from movement, during the period of the intravenous infusion.
  • the rigid intravenous needle structure of this invention includes an integral U-shaped needle which can be directly connected to an infusion tube, which is in turn connected to a source, e.g. a bottle, of infusible liquid.
  • the rigid intravenous needle structure of the present invention comprises a nonintegral construction comprising a substan tially straight needle element connected to a curved rigid tube member comprising a connector means designed and adapted to be contacted to the infusion type apparatus.
  • FIG. 2 is an elevational view in perspective showing a needle constructed in accordance with this invention and the manner in which it is attached to the tubing;
  • FIG. 3 is a view similar to FIG. 2, but showing an alternate embodiment wherein the needle is straight, but is connected to a curved adapter or connecting element;
  • FIG. 4 is a longitudinal view in perspective showing yet another alternate embodiment of the invention comprising a straight intravenous needle in combination with a housing.
  • FIG. 5 is a longitudinal view in perspectiveshowing another alternate embodiment of the invention wherein a straight needle is utilized in combination with a housing having an intersecting passageway therein.
  • FIG. 6 is a longitudinal view in perspective of an embodiment alternate to the embodiment of FIG. 4 wherein an alternate type of connection is provided for the needle at one end of the curved passageway in the housing member.
  • FIG. 7 is a view in perspective of yet another embodiment wherein a straight needle is used in combination with a housing member having intravenous tubing embedded or sandwiched therein.
  • FIG. 8 is a cross-sectional view through a vein following the insertion of the pointed rigid portion of the needle construction of the present invention through the flesh of the patient and into a vein.
  • FIG. 1 shows an overall stylized view of a standard intravenousinfusion apparatus attached to the arm of the patient. As shown,
  • the bottle is located above the level of the arm and generally behind the arm, i.e. generally over the shoulder of the patient,
  • An infusion tube 12 extends from the bottle 10 and is in fluid flow connection therewith. Thetube 12 is then conventionally connected to the intravenous needle which is inserted into the body of the patient.
  • infusion tube 12 is connected to the curved needle in accordance withthe present invention, indicated generally by the numeral 14 and shown in greater detail in FIG. 2.
  • the tube 12 is connected to the integral needle 14 'by a standard universal intravenous tubing coupling comprising the converging tubing member 15 and the hub 16 in rigid connection with the curved, rigid needle portion 18.
  • the construction of the curved, rigid needle portion 18 permits the use of a straight, flexible tubing line 12, without need of reverse loops, and avoids the problem of movementof the needle relative to the arm of the patient.
  • the center lines of the needle 18 and of hub 16 are optimally in the same plane and the angle formed therebetween should be from about 150 to about l80.
  • the curved needle structure 14 is held onto the arm of the patient merely by a flexible adhesive strip 20 and there is no need for immobilizing the arm of the patient in any other manner.
  • the intravenous needle structure of FIG. 3 comprises a two-part rigid construction.
  • the rigid needle member 22 has a hub 24 in rigid connection therewith and is generally formed integrally therewith. Attached to this rigid needle member is a rigid, curved tube member 26 in fluid-tight connection with the hub 24 of needle 22 at one end and comprising a hub 28 at its other end, designed-and adapted to fit a standard universal I.V. coupling as shown in FIG. 2.
  • the rigid tube 26 can be formed of a rigid, transparent oropaque plastic or other rigid material such as metal or hard rubber.
  • the central line of curved tube .26 and of the rigid needle member 22 form a single plane and the angle between the central lines are preferably from about 150 to 180. It should of course be noted that when an angle of 180 is referred to, it means that the two central lines are parallel.
  • FIG. 4 A three-piece embodiment of the curved intravenous needle structure in accordance with the present invention, is shown in FIG. 4.
  • a rigid needle member 30, having agenerally straight construction is attached via hub 32, formed integral therewith, to the interior of a curved, tube member 34, formed integral with a flat housing 36.
  • the second end of the curved tube 34 is connected to a standard universal I.V. hub portion 38 which can be connected to a conventional intravenous infusion tubing as shown in FIG. 2, for example.
  • the housing 36 and integrally formed tubing 34 have the advantage of being readily moldable and providing a flat surface for direct attachment to the hand or arm of the patient.
  • the one side of the housing member 36 can havean adhesive material applied thereto which can be directly adhered to the body of the patient.
  • the device of FIG. 4 can, for example, be constructed to two substantially rigid flat sheets 36a, h of plastic or other rigid material, each having formed into its surface a generally U-sahped depression in accordance with FIG. 4.
  • the straight needle member and hub 38 can-then be placed within the two ends of a U-shaped depression in one piece 36a, the second sheet applied thereover and the sandwich sealed together as byconventional heat sealing methods, when, in the preferred embodiment, the sheets 36a, b are formed of a thermoplastic material.
  • a conventional adhesive material such as a thermoplastic resin, can be utilized to seal the ends of the tube 34 onto needle 30 and the hub 38.
  • the individual sheets of the housing 36a, 12, and the sandwich housing 36 can be flexible so as to bend around the horizontal and vertical axes A and B in and out of the plane of the sheet, but the relationship between needle 30 and hub 38 Le. the angle formed between the two members, will not be affected.
  • Such a housing, which is flexible in two planes, is useful, for example, for affixing the needle in a scalp vein.
  • FIG. 5 is another alternative embodiment, including a housing as shown in FIG. 4, but including a second intersecting passage way 40 molded into the housing members 42 substantially in line with the straight rigid needle member 44.
  • the housing is again formed of two molded sheets 42a and 42b adhered together to form the tubes 40 and 46, to which are attached the needle 44 and the hub portion 48 in the same manner as described above for FIG. 4.
  • the housing is formed in substantially the same manner as in FIG. 4, however the needle comprises a conventional intravenous needle including a standard I.V. hub 50 and the straight needle portion 52.
  • a coupling element comprising a converging tube 54 is adhered and placed into the partially flexible housing 56 (again, formed of two adhered sheets 56a and 56b), the second end of the U-shaped tube 57 is connected to a standard I.V. hub 58 in the same manner as shown in FIGS. 4 and 5 above.
  • FIG. 7 Yet anotherembodiment of the partially flexible housing is shown in FIG. 7 where the I.V. tubing is embedded between the housing sheets 60 and connected to a coupling member 62 to fit into the standard I.V. needle 64 including a straight needle portion 65 and a conventional hub 66.
  • the tubing and plastic housing can be formed of conventional rigid and flexible plastic materials including polyethylene, polypropylene and polyvinylchloride, as well as acrylic materials, where a rigid member is required.
  • the needle referred to in each case can be a conventional intravenous needle, generally formed of stainless steel.
  • the stopper shown in the intersecting channel 40, in the housing of FIG. 5, can be removable or can be formed of rubber, or other self-sealing material, which can be punctured by, for example, a hypodermic needle, in order to inject orobtain samples of material from the vein into which the intravenous needle 44 is inserted.
