Definitions

  • the invention relates to a unit consisting of an infusion bottle with a permanently attached drip chamber.
  • the bottles used hitherto for infusion solutions are constructed in such a manner that, for use as an infusion apparatus, they consist of a drip chamber, a connecting tube and an injection device which can be connected to them. If bottles made of glass or stifi plastic are used, air venting must also be provided.
  • a container unit for infusion solutions which consists of a thin-walled, flexible, bottleshaped container of synthetic material which terminates in a drip chamber that serves as a stopper for the container and is equipped with a dropper and sealed by a membrane, and is covered by a protective cap which is connected with the container through a seal.
  • a modified infusion apparatus In the space between the cap and the upper portion of the container unit, which is constructed as a drip chamber, there is contained a modified infusion apparatus.
  • one aspect of this invention resides in an infusion bottle having a bottle portion and an integral drip chamber with a neck therebetween.
  • the drip chamber has elastically deformable walls and has a puncturable diaphragm across the mouth thereof opposite to the neck.
  • a puncture means is provided adapted to puncture the diaphragm and also fit into the neck and act as a dripper.
  • the rearward portion telescopes at its forward end over the rearward end of the forward member and is adapted to releasably engage such forward member.
  • the rearward member is adapted to fit into the mouth of the dripper and has a flange means extending therefrom adapted to support pressure exerted thereon sufficient to invert said drip chamber and insert said forward member into said neck.
  • the infusion bottle of this invention have a bottle portion terminating in a conical portion directed toward the neck and a drip chamber portion having conical portions directed toward both the neck and the mouth. It is preferred to provide a multiplicity of rib portions extending about the neck between both conical portions.
  • FIG. 1 of the drawing shows an exploded view of the combination according to the invention before it is made ready for use.
  • FIG. 2 shows a ready-for-use combination after the piercing needle has been pushed in.
  • FIGS. 3 and 4 show the introduction of the piercing needle.
  • FIG. 5 shows a preferred embodiment of the invention in which the drip chamber 2 is set on a kind of bottle neck.
  • FIGS. 6 and 7 show the cross section of a preferred piercing needle 5 having a correspondingly constructed oval piercing cross section.
  • the infusion container with the permanently attached drip chamber consists of a thin-walled container 1 made of preferably flexible plastic, especially polypropylene, and it is advantageously in the shape of a bottle.
  • plastics are generally used which are transparent or translucent in the necessary wall thickness and can be sterilized, preferably by steam.
  • Container 1 terminates in part 2, which serves as a drip chamber and serves instead of the formerly customary stoppers to seal the container.
  • This container portion 2 is sealed by a membrane 3.
  • Container portion 2 and membrane 3 are manufactured together with container 1 in a single process and form the same material.
  • an adhered aluminum tear-off strip 4 which is welded onto the closing membrane, serves as the closure.
  • ribs 7, four ribs can be disposed on or around the lower portion of the drip chamber 2, for the purpose of supporting chamber 2 and protecting it against damage.
  • This container 1 is filled with liquid only to such an extent that the space in drip chamber 2 is empty, i.e., contains only air or other gas, and to prepare it for use, a two-piece piercing needle, composed of parts 5 and 6, is introduced into it, tip 6 serving for the piercing and, in the final position (FIG. 2), serving as the dripper.
  • tip 6 is pushed through membrane 3 by the squeezing of drip chamber 2, until the sharp portion 6 is pressed into the narrow portion between container portions 1 and 2 (cf. FIG. 3).
  • the connection to the patient is established by a regular flexible tube with conventional regulating devices and needle (not shown).
  • the combination according to the invention has the advantage that container and drip chamber as well as the stopper unit can be manufactured in a single operating procedure. Another advantage consists in the fact that it is not necessary to keep the drip chamber separately sterile and store it separately.
  • An infusion bottle comprising a bottle portion terminating at one end in a neck passageway; a drip tube in said indicated passageway which has a sharp pointed end directed toward said bottle portion; a drip chamber integral with said bottle portion extending from said passageway and communicating with said bottle portion through said drip tube in said indicated passageway and terminating in a mouth disposed opposite to said indicated portion; a couple tube in said mouth having a transverse flange therearound outside the tube portion thereof inserted in said mouth; and the remanents of a frangible diaphragm about said mouth wherein said drip tube and said couple tube are adapted for telescopically engaging with each other with the point of said drip tube adapted to rupture a frangible diaphragm sealing said mouth, elastically deforming the walls of the drip chamber between said mouth and said indicated passageway whereby permitting the insertion of said drip tube into said indicated and said couple tube in said mouth.
  • a bottle as claimed in claim 1 wherein said drip chamber comprises a pair of facing conical sections with the narrow portions thereof constituting said mouth and a portion of said neck.
  • a bottle as claimed in claim 2 including a multiplicity of substantially solid fins surrounding said neck between said drip chamber portion and said bottle portion.
