Definitions

  • the present invention is directed to a pouch for the collection of any liquid or semisolid body waste material and, more particularly, a drainable pouch that can be closed during collection and opened and drained as desired.
  • Drainable pouches for the collection of liquid or semisolid material such as body waste are well known and typically include flat opposing sidewalls secured together along their edges to define a collection chamber.
  • One of the walls is ⁇ provided with an opening to receive a stoma, and means are provided for securing the pouch to a patient so that body waste material that is discharged from the stoma is received in the chamber.
  • the drainable pouch typically has a discharge opening which maybe closed during collection of the liquid or semisolid body waste material that passes through the stoma but may be opened for draining the material from the pouch.
  • the drainable pouch will typically be provided with a closure for the discharge opening that may take a number of different forms so long as it serves to prevent leakage of the body waste material.
  • a drainable pouch is typically reusable following periodic emptying of the body waste material, but it is important that the pouch be provided with effective sealing in order to avoid any real possibility of odors or contents emanating from the resealed pouch. This requirement is coupled with a further need for the pouch to be easily and conveniently drainable either directly through the discharge opening, or by reason of connecting an ancillary drainage device in a secure manner to the discharge opening of the pouch. Users of drainable pouches often encounter difficulty and discomfort in unsealing, emptying, and resealing the pouches because of the nature of the drainage systems and manipulations which require greater dexterity than many patients possess.
  • drainable pouch drainage systems are typically formed of bulky, rigid components that are known to cause physical discomfort and visual anomalies to the patient. It would be desirable to be able to substitute soft components which have a low profile while at the same time reducing manufacturing costs. In addition, drainable pouches would be greatly improved with controllable flow during drainage and a tactile feel or audible noise during unsealing and resealing procedures.
  • the present invention is directed to overcoming one or more of the foregoing problems and achieving one or more of the noted objectives.
  • the drainable pouch of the disclosure has sidewalls of flexible sheet material which define a body portion having a cavity therein.
  • the body portion has a discharge end provided with a compliant internal adapter forming a discharge opening for draining the contents of the pouch.
  • the pouch also includes a two-part external fastener system for closing and opening the discharge opening formed by the compliant internal adapter.
  • the two-part external fastener system includes first and second fastener parts having locking elements that can be brought into releasable engagement when the discharge end of the pouch is folded.
  • the first and second fastener parts cooperate with the compliant internal adapter to cause the discharge opening to be maintained in a closed position after the locking elements have been brought into releasable engagement by folding the discharge end of the pouch.
  • the . pouch is thereafter drainable by releasing the locking elements of the first and second fastener parts from engagement and unfolding the discharge end of the pouch to open the discharge opening formed by the compliant internal adapter for draining the pouch through the discharge opening.
  • the discharge end of the pouch is a tubular neck portion either integrally formed with the body portion of the flexible sheet material of the sidewalls or separately formed from but integral with the flexible sheet material of the sidewalls.
  • the discharge end of the pouch is advantageously folded upwardly toward one of the sidewalls for bringing the locking elements into releasable engagement and is folded downwardly away from the one of the sidewalls after releasing the locking elements from engagement.
  • the compliant internal adapter is preferably a soft, flexible insert which is in sealed engagement within the tubular neck portion of the pouch either compressed between the first and second fastener parts or extending beyond them in the closed position.
  • the insert is generally oblong shaped and has a narrow opening comprising the discharge opening to receive a connector on a drainage device.
  • the narrow discharge opening in the soft, flexible insert may either be nominally open or it may be nominally closed.
  • the compliant internal adapter may comprise the inner surface of the tubular neck portion itself.
  • one of the first and second fastener parts is located nearer the discharge end of the pouch than the other of the first and second fastener parts.
  • the first and second fastener parts are disposed on the same sidewall such that the locking elements can be brought into releasable engagement by folding the pouch one time. In another embodiment, the first and second fastener parts are disposed on opposite sidewalls of the pouch such that the locking elements can be brought into releasable engagement by folding the pouch two times, hi still another embodiment, the first and second fastener parts are disposed on opposite sidewalls of the pouch such that the locking elements can be brought into releasable engagement by folding the pouch at least three times.
  • the drainable pouch can advantageously be provided with a sidewall pocket or tab for receiving and securing the discharge end of the pouch after it has been folded to bring the locking elements into releasable engagement.

Abstract

La présente invention a trait à une poche vidangeable comportant des parois latérales de matériau flexible en feuille définissant une portion de corps renfermant une cavité. La portion de corps comporte une extrémité d'évacuation munie d'un adaptateur interne souple formant un orifice d'évacuation pour le vidange du contenu de la poche. La poche comporte également un système d'attache extérieur en deux parties pour l'ouverture et la fermeture de l'orifice d'évacuation formé par l'adaptateur interne souple comprenant des première et deuxième parties d'attache incluant des éléments de verrouillage qui peuvent être engagés de manière réversible lorsque l'extrémité d'évacuation de la poche est repliée. Les première et deuxième parties d'attache coopèrent avec l'adaptateur interne souple pour entraîner le maintien de l'orifice d'évacuation dans une position fermée suite à l'engagement réversible des éléments de verrouillage par le repli de l'extrémité d'évacuation de la poche. La poche est ensuite vidangeable par la libération des éléments de verrouillage des première et deuxième parties d'attache de leur engagement et le dépliage de l'extrémité d'évacuation de la poche pour ouvrir l'orifice d'évacuation formé par l'adaptateur interne souple pour le vidange de la poche à travers l'orifice d'évacuation.
