Definitions

  • An apparatus for injecting liquids into a living body having a reservoir for the liquid to be injected.
  • a conduit is connected at one end of the reservoir and a closing device is connected to the other end of such conduit.
  • a joining device connects a pipette to the closing device and a second conduit connects the pipette to an injection member.
  • the closing device is of glass and has a break able portion at a point adjacent the arriving liquid to the pipette.
  • the joining device is releasably connected to the second conduit whereby a plurality of reservoirs may be attached to the injection device without disturbing the injection needle.
  • Apparatus for the infusion of liquids into a body, of which the reservoir, the pipette device and the injection needle form a single unit, which are sterilized during their manufacture, and which are, without further ado, ready for use. They are further equipped with a closing device, liable to be broken from the outside, to allow a passage for the liquid.
  • These apparatus offer the advantage that it is not necessary to expose their contents or their interior to outer contact in order to causethem to operate since the release of the flow of liquid is effected by breakage of the closing device from their outside.
  • the present invention permits this replacement.
  • It has for object an apparatus for the infusion of liquids into a body comprising a reservoir for the liquid to be infused, a duct connecting this reservoir to a pipette device, a closing device breakable at a definite point, closing said duct and a joint removably connecting the duct to the pipette device.
  • This apparatus is characterized in that the said closing device is secured in the end of the duct connected to the pipette device, and in that the portion of said closing device releasable by the break is upstream of that remaining fixed to the duct.
  • the portion of the closing device released by the break is held in said duct by the portion of the closing device remaining fixed to the duct.
  • the reservoir, the duct and all the broken closing device may be removed from the rest of the apparatus and replaced by another reservoir associated with a duct closed by a closing device still intact.
  • the breaking of the closing device may be effected from the outside, once the reservoir and its duct are connected to the pipette device.
  • the interchangeable reservoir with its duct and the closing device form a single unit during their manufacture.
  • FIGURE 1 is a view in elevation of the complete apparatus and FIGURE 2 is a section on a larger scale of the portion of the apparatus constituted by the closing device, the pipette device and the joint connecting the end of the duct to the pipette device.
  • the apparatus shown comprises a reservoir 10, of flexible plastic material, adapted to contain the liquid to be infused, for example a physiological solution of sodium chloride.
  • This reservoir has an attachment member 11 of one piece therewith, permitting of suspending the same. It is welded opposite the attachment member to a duct 12, also of plastic material.
  • This duct 12 encloses, at its end opposite to the reservoir 10, a closing device 13; it is connected in a'removable manner to a pipette device 14 by a joint 15.
  • a flexible duct 16 connects the pipette device 14 to the injection member 17 the essential part of which is an injection needle (not visible in FIG. 1) and protected, before use, by an elastic cap 18.
  • the closing device 13 is secured by friction in the end of the tube 12.
  • This closing device is in glass; it comprises a full portion 19 and a recessed portion 20. This latter, of larger diameter than the portion 19, is forced into the end of the tube 12 and is secured therein.
  • the recess of the portion 20 is conical adjacent to the full portion 19, so that the closing device has a weak part at 21, which is the breaking part.
  • the closing device has, at its portion adjacent to the pipette device 14, a shoulder 22. This latter is capped by an inwardly tapped collet 23. This collet is screwed on a downstream element 24 and forms, with the latter and with the closing device 13 and its shoulder 22, the joint between the duct 12 and the pipette device 14.
  • the shoulder 22 form a washer; the downstream element 24 has an axial duct 25 as an extension of the recess of the portion 20 of the closing device.
  • the down-stream element 24 is secured to the chamber 26 of the pipette device; it is provided, of one piece therewith, with a pipette tube 27 extending into the chamber 26.
  • This latter which is of rigid transparent material, has an extension 28 at its lower end, on which is secured the duct 16.
  • the reservoir 10 being suspended by the attachment member 11, the glass closing member 13 is broken at 21 by a bending effort exerted from the outside of the duct 12. From this moment, the liquid contained in the reservoir 10 flows to the pipette tube 27, where drops are formed which fall into the chamber 26. From there, the liquid flows to the injection member 17 the needle of which has been exposed by removal of the cap 18. The liquid reaching the needle, the latter may be inserted in a vein of the patient.
  • portion 19 of the closing device which has been released by the 'break, is up-strearn of the portion 20 remaining secured to the duct 12.
  • this portion 19 remains held in the duct 12, without hindering the flow of the liquid and without the risk of falling into the pipette device.
  • the reservoir 10 may be replaced by another reservoir by unscrewing the collet 23 to free it from the down-stream element 24.
  • the reservoir 10, the duct 12, the broken closing device 13 and the collet 23 form a unit which may be discarded and replaced by a similar unit, of which the closing device is still intact and the reservoir filled with liquid.
  • This replacement is very rapid because it is sufiicient to screw the collet 23 of the new unit on the threaded portion of the element 24.
  • This latter together with the chamber 26 of the pipette device, the duct 16 and the injection member 17 have remained in communication with the body of the patient, the injection needle not having been withdrawn from the spot where it had been inserted.
  • the replacement of a reservoir by another may be effected as many times as required, while leaving the injection needle in the same place in the body of the patient.
  • Apparatus for the infusion of liquids in a living body comprising a reservoir for the liquid to be infused, a first conduit connected at one end to said reservoir for drawing off liquid from said resrevoir, a closing device connected to the other end of said conduit, a pipette, a joining device connecting said closing device and said pipette, a second conduit connected to said pipette for drawing off said liquid from said pipette, an injection member connected to said second conduit, said closing device having a breakable portion at a joint adjacent the arriving liquid to said pipette for permitting a free flow of said liquid, said closing device comprising a glass tube secured to the end of said first conduit having said breakable portion which is solid and of smaller diameter than that portion of said glass tube secured to said conduit, and said glass tube having a conical recess adjacent said breakable portion.
  • Apparatus for the infusion of liquids in-a living body comprising a reservoir for the liquid to be infused, a first conduit connected at one end to said reservoir for drawing off liquid from siad reservoir, a closing device connected to the other end of said conduit, a pipette, a joining device connecting said closing device and said pipette, a second conduit connected to said pipette for drawing off said liquid from said pipette, an injection member connected to said second conduit, said closing device having a breakable portion at a point adjacent the arriving liquid to said pipette for permitting a free flow of said liquid, said closing device comprising a glass tube secured in the end of said first conduit having said breakable portion, said glass tube having an annular shoulder situated outside said first conduit adjacent said pipette, and said pipette comprising a cylindrical chamber having a cap with an axial duct, said cap being rigidly secured to the inlet end of said chamber and adapted to be releasably secured to said joining device, said axial duct having
