Definitions

  • This invention relates to pouch-like bags for containing liquids for medical or surgical use, such as a liquid for intravenous injection by means of a hospital drip feed system.
  • the bag should be capable of receiving a dispensing needle which will connect to the drip feed system, and an injection needle by which a drug can be injected into the liquid before it is administered to a patient.
  • the formation or formations provided for this purpose should be sterile and protected from con ⁇ tamination.
  • Such bags have previously, been made with tubular - inserts sealed into an edge portion of the bag to. form ports for insertion of needles and with sealed tear-off chambers outboard of the ports, as described in British Patent Specification No. 1,544,811, for example. fe is an object of the present invention to provide an economical construction of, and method of making, such a bag, which will be especially convenient in use. .
  • a pouch-like bag for containing a liquid for medical or surgical use having two walls formed by respec ⁇ tive plies of flexible plastics material sealed together around their periphery, wherein the bag is provided with an elongate insert of polymeric material which is capable of self-sealing a puncture made transversely through the insert, the insert being sealed between the plies of flexible material so as to extend adjacent to a portion
  • a tearable tag which, when torn off the bag, es ⁇ poses at least part of the length of the said insert, along a side face thereof, so as to allow an injection or dispensing needle access to penetrate transversely through the insert and into the bag.
  • each ply of flexible material has first, inner, and second, outer, layers formed respec- tively of linear low density polyethylene and oriented polypropylene, the first layers of the two plies being heat-sealed to one another around their periphery.
  • the material is weakened adjacent the insert to form a tear line along the base of the tearable "ta :.
  • the insert has a lenticular cross-section with a notch or groove facing outwards of the bag and forming a shaped portion to guide a needle into correct position for penetration transversely through the insert.
  • the notch or groove may be held in closed position, at least at each end of - the insert* by the peripheral seal of the extreme portions of the plies of plastics material, but will open on tearin off the tag.
  • the insert preferably has a core adapted to " be easily punctured by an injection needle but to seal closely around the needle and to re-seal the puncture afte withdrawal of the needle, and an outer skin suitable for heat sealing to the plies of plastics material.
  • the core is of an elastomer, a foamed polyolefin, polyolefin blend or rubber modified poly- olefin, and the outer skin is of a heat sealable non- foamed polyolefin.
  • This construction is particularly suitable for use with a hypodermic needle of the size which is used with intravenous fluid bags for injection of a drug.
  • the insert may extend diagonally across a substan ⁇ tially rectangular corner of the bag, so that the tearable tag is substantially triangular.
  • the insert may extend between the peripheral seals on opposite sides of the bag, substantially parallel and adjacent to the peripheral seal along a lower edge of the bag, so that the tearable tag is substantially rectangular.
  • the tearable tag may be subdivided by a weakening line at right angles to the insert,, so as to provide independent access to two different parts of the insert, e.g. for insertion of two different needles.
  • a pouch-like bag for containing a liquid for medical or surgical use having two walls formed by respec ⁇ tive plies of flexible plastics material sealed together around their periphery, particularly a bag provided with an insert as described above, wherein the bag is formed with a pair of inward extensions of the peripheral seal between the two plies, defining a passage adapted to guide an injection or dispensing needle into the interior of the bag, and a further seal between the plies joining the inner ends of the extensions to form a frangible closure of the inner end of the passage, and extreme portions of the plies of flexible material which extend outboard of the passage are sealed together so as to close the outer end of the passage and to form a tearable tag which, when torn off the bag, exposes the said passage.
  • This construction is particularly appropriate for use with the needle of a conventional hospital drip feed system, which is of larger diameter than a hypodermic needle.
  • the frangible seal may be pervious to liquids, in order to ensure that, during a prel___minary sterilisation of the bag> the interior of the passage will be filled with the sterilising liquid.
  • the invention also resides in a method of making a pouch—like bag for containing a liquid for medical or surgical use by sealing two plies of flexible plastics . material together around their periphery, wherein the method includes the steps of first sealing between the plies an elongate insert of polymeric material which is capable of self-sealing a puncture made transversely . through the insert, with said- insert extending adjacent to a portion of the periphery of the plies, and subsequen ⁇ tly effecting the peripheral seal between the plies, including sealing extreme portions of the plies together outboard of the insert to form a tearable tag which, when torn off the bag, will expose at least part of the length of the said insert, along a side face thereof.

Abstract

Une poche en forme de sac (10) possède deux parois en plastique flexible scellées autour de leur périphérie. Les parois sont de préférence laminées, la couche interne étant en polyéthylène linéaire de faible densité et la couche externe en polypropylène orienté. La poche est pourvue d'une pièce rapportée allongée (14) pouvant s'auto-adapter de manière étanche dans une ouverture transversale, et placée adjacente à la périphérie de la poche, et les parties scellées périphériques des parois de la poche à l'extérieur de la pièce rapportée forment un coin ou étiquette déchirable (11) qui, lorsqu'elle est détachée par déchirement, expose un côté de la pièce rapportée formée de préférence avec une rainure ou encoche (15) permettant de guider une aiguille pénétrant transversalement au travers de la pièce rapportée dans la poche, p.ex. pour l'injection d'un médicament dans la poche. La poche peut également avoir une paire d'extensions dirigées vers l'intérieur (19) du joint périphérique (18) définissant un passage (20) pour guider une aiguille d'injection d'un système d'alimentation de goutte à goutte dans la poche, le passage ayant un joint frangible (21) à son extrémité intérieure et étant fermé par un coin déchirable (12) à son extrémité externe. En cours de fabrication de la poche, la pièce rapportée peut d'abord être scellée entre les couches en matériau plastique formant les parois, après quoi le joint périphérique (18) est effectué en même temps que les coins déchirables sont formés. Un espace (22) peut être laissé au niveau de la partie supérieure de la poche, lequel est scellé après avoir rempli la poche au travers de l'espace.
