Definitions

  • This invention relates to a flexible tubular portion of a parenteral administration set and, more particularly, to a flash-back indicator.
  • parenteral fluids In the administration of parenteral fluids, it is customary to ascertain whether or not the hypodermic needle through which the fluid enters the body has punctured a vein. This is important in many instances because the therapy to be achieved by the parenteral fluid can be brought about best by either subcutaneous or intravenous injection. Further, subcutaneous injection of a fluiddesigned to be injected intravenously may be very painful to the recipient.
  • the essential elements of a parenteral administration apparatus usually include a container source of the parenteral fluid and an administration set leading from this source to the body of the recipient.
  • the administration set includes a length of flexible tubing, which is provided at'one end with a connector suitable for connecting the flexible tubing to the source of parenteral fluid and provided at the other end with a hypodermic needle suitable for insertion into the body of the recipient.
  • a short length of rubber tubing is inserted which is useful in determining whether a vein has been punctured.
  • the above-mentioned length of rubber tubing is subject to two distinct disadvantages. Since it is of a relatively small diameter, the aspirating effect achieved by squeezing it is minimal, so it is often diflicult to cause blood to flash back into the administration set. Secondly, it is a delicate operation to insert in it the needle of a separate hypodermic syringe containing additional medication.
  • Still another object is to provide a flashback indicator which expedites the administration of supplemental medication.
  • FIG. 1 is a perspective view of a parenteral administration apparatus
  • Fig. 2 is an enlarged elevational view partially in section of the flash-back indicator portion of the parenteral administration apparatus set forth in Fig. 1..
  • a perspective view of a parenteral administration apparatus is shown.
  • the apparatus includes a source of parenteral fluid designated 10, which in the usual embodiment is a glass bottle 1.1 suspended in a mouthdownward condition.
  • the downwardly extending mouth 12 of bottle 11 is closed by stopper 13, which is provided with a pair of passages 14 and 15 extending therethrough.
  • Passage 14 permits the entrance of air into bottle 11 through air-tube 16 to replace parenteral fluid 17 flowing out through liquid outlet passage 15.
  • Parenteral administration set 19 in addition to connector 18 includes a length of flexible tubing 20, generally constructed of a plastic material, which is attached at one end to connector 18. As shown in Fig. l, a drip housing 21 may be inserted in the length of flexible tub ing 20 so as to provide a visual means for determining the rate of flow of parenteral fluid 17. Clamping means are usually provided with a parenteral administration set and may take the form of hemostat 22, shown clamped on tubing 20.
  • flash-back indicator 24 mounted on the portion of stilfener 23 external to tubing 20. Flash-back indicator 24 at its opposite end is connected to hypodermic needle 25, which has been previously provided with shank portion 26, on which flash-back indicator 24 has been mounted.
  • Flash-back indicator 24 can be seen more clearly by reference to Fig. 2.
  • flashback indicator 24 is generally tubular in construction and is provided with an integral, intermediate wider portion 27 and constricted end portions 28.
  • annular sloping shoulder portion 29 is provided at the point Where the wider portion 27 of indicator Z4 tapers inwardly to join constricted portion 28;
  • the preferred embodiment of my invention has constricted portions at both ends of indicator 24.
  • tthe end 28 of indicator 24 mounted on needle shank 26 is of considerably larger size than the opposite end 28a mounted on tubing stiffener 23.
  • An obvious modification is to dispense with. constricted end 28 altogether by providing an adapter of larger outside dimensions for needle shank 26.
  • indicator 24 I have found superior results to be achieved by using rubber as the material of construction for indicator 24.
  • the preferred method for producing indicator 24 is by molding, although the same can be achieved by dipping a form constructed according to the inner dimensions of indicator 24.
  • the flash-back indicator is constructed of a material adapted to reseal itself after being punctured by a hypodermic needle.
  • a plastic material may be used and the same formed by extruding, followed by expanding, an intermediate portion of the same.
  • Still another method useful in forming the indicator of my invention when the same is constructed of a thermoplastic material is to utilize the structure set forth in the commonly owned patent, George R. Bent, No.
  • Indicator 24 lends itself particularly to expeditious administration of supplemental medication, as by the puncture of wider portion 27 by hypodermic needle 30, shown in fragmentary form.
  • desired supplemental medication which may be a barbiturate or any other parenteral fluid desired
  • hypodermic needle 30 may be removed from wider portion 27, whereupon the flexible material of which indicator 24 is constructed will reseal itself, preventing contamination of the recipient by foreign material from the atmosphere.
  • a flash-back indicator for a parenteral administration set comprising a flexible tubular member having a finger-squeezable intermediate chamber portion of greater cross-sectional area than that of the end portions of the said tubular member, said flexible tubular member being constructed of a material adapted to reseal itself upon puncture by a hypodermic needle whereby the administration of supplemental medication is expedited.
  • a tube and needle administration set including a length of flexible tubing having bottle connection means at one end and recipient needle means at the other end, the improvement comprising a flexible tubular member inter-connected between said tubing and said needle, said tubular member being constructed of a material capable of rescaling itself after hypodermic needle puncture and having an enlarged chamber portion spaced from the end thereof connected to said tubing, whereby squeezing and releasing said chamber portion causes blood to be as-- pirated into said chamber when said recipient needle means has penetrated the vein of an intended recipient.
  • a parenteral administration set comprising a length of flexible tithing connected at one end thereof with a bottle source of parenteral fluid, means stiffening the other end of said tubing, a flexible tubular member mounted on the stiffened portion of said tubing, said tubular member being so constructed as to reseal itself after puncture by a hypodermic needle and having a diameter on its end mounted on said tubing approximately the size of said tubing, a portion of said tubular member spaced from the mounted portion thereof being of substantially larger diameter than the mounted portion, and a hypodermic needle assembly mounted in the end of said tubular member remote from the tubingmounted end.
