Definitions

  • the invention relates to a connector for an infusion bag and an infusion bag provided with such a connector.
  • the invention typically applies to containers for the intravenous administration of medical fluids to a patient.
  • the invention applies to the infusion bag connectors.
  • the flexible bags are generally made by welding a film or a flexible sheath. To allow access to the inside of the pocket, they are provided with one or more connectors, generally in the form of tubes. One of the connectors forms the injection site allowing the introduction into the bag of an additive such as a drug, and the other forms the infusion site for removing the solute from the bag by connecting a perforator.
  • the perfusion site is adapted to receive the perforator of an infusion line and advantageously comprises a first pierceable membrane and, at a distance from this first membrane, a second perforable membrane - said self-resealing - which closes after removal of the perforator .
  • This infusion site is also provided with a cap protecting the access to the self-resealing membrane until it is used.
  • the injection site for the introduction of an additive into the bag is also provided with a self-resealing membrane which can be pierced by the needle of a syringe or a transfer device.
  • the document EP 0 011 144 discloses a connector for infusion bag comprising a tube, a bowl placed in the tube, whose bottom forms a flat diaphragm and in which is arranged a membrane, and a breakable stopper.
  • the document WO 2006/071781 discloses an infusion bag connector system comprised of two types of ports: an addition port for connecting a needle and an administration port for connecting a perforator.
  • the port of addition is formed of an assembly which comprises: (a) a closure body comprising an open cylinder in which is placed a flat diaphragm open to the flow of fluid once pierced by a needle, (b) a plug assembly comprising a shell surmounted by a removable plug, and (c) a self-resealing membrane placed between the closure body and the plug assembly which is mechanically held in the assembly.
  • the administration port is formed of an assembly which comprises: (a) a second closure body comprising a sleeve whose upper portion is tapered so as to be able to connect different sizes of connectors, and (b) a second similar cap assembly to the plug assembly of the port of addition.
  • U.S. 4,632,673 discloses an injection or infusion site either directly welded to a pocket wall, or placed on the inlet or outlet tube of the pocket.
  • the injection site is formed of a connector in the form of a tube on which or in which is disposed a pierceable rubber pellet.
  • a flexible protective film is arranged under the pellet.
  • Another flexible film forming a cap and provided with a tearable tab covers the pellet.
  • the various elements of this connector are assembled by adhesion. These flexible films conform to the shape of the pellet but do not compress it, so that if adhesion is defective, tightness and sterility are no longer assured.
  • connectors In the first place, they must be easy to mount on the infusion bags. Then they must be waterproof to avoid contaminating the contents of the pocket. In particular, this seal must be maintained during the sterilization step, in particular when steam sterilization which makes the connectors suffer from high deformation stresses. Finally, the connectors must be easy to handle for the nursing staff.
  • the connector of the invention has a particular structure enabling it to ensure a good seal, especially during sterilization by steam.
  • the invention proposes a connector for an infusion bag comprising at least a first tubular body forming an access orifice, said tubular body being equipped with a sleeve having a perforable transverse partition intended to ensure the tight closure of the access port, a perforable shutter sealingly disposed on said transverse partition, and a cap for compressing on the tubular body said perforable shutter mounted on said sleeve, the surface of said transverse partition in contact with the perforable shutter being curved so as to locally increase the compression of said perforable shutter between said cap and said tubular body.
  • upstream and downstream are defined relative to the flow direction of the fluid from the inside of the pocket to the outside.
  • the invention relates to a connector for an infusion bag and an infusion bag comprising such a connector.
  • the pocket 1 is represented on the figure 1 .
  • the pocket 1 is formed of two flexible sheets associated with each other along a peripheral seal 2.
  • the pocket is formed of a flexible sheet folded on itself or a flexible sheath.
  • the bag is made in particular of a flexible and sterilizable thermoplastic material such as polyvinyl chloride, a polyolefin, ethylene vinyl acetate.
  • a connector 3 disposed between the walls of the bag and comprising at least a first and second tubular body 4,5 each forming an access port to the inside volume of the pocket.
  • the first tubular body 4 forms an infusion site adapted to receive the perforator of an infusion line for administering fluid contained in the bag to a patient.
  • the second tubular body 5 forms an injection site adapted to allow the introduction of an additive, such as a drug solution, into the internal volume of the bag, via a syringe or a device transfer.
  • the connector of the invention comprises at least a first and second tubular body 4,5 each forming an access port, and a base 6 extending around said first and second tubular body 4,5, said base 6 being formed of a plate 7.
  • the base 6 serves to support the tubular bodies 4,5 so as to form a unitary piece easily manipulated.
  • the base 6 is formed of a plate 7, solid, thin and having a substantially flat surface.
  • the plate 7 is arranged in a plane of symmetry of the tubular bodies 4,5.
  • the thickness of the wafer 7 between the two tubular bodies 4,5 is in particular smaller than the outer diameter of the tubular bodies 4,5, generally of the order of one millimeter, in particular less than one millimeter.
  • the thickness of the wafer 7 is for example of the order of 0.8 mm.
  • the thickness of the wafer increases in the direction of the tubular bodies to a thickness substantially equal to that of the outer diameter of the tubular bodies, thus having, in cross-section with respect to the axis tubular bodies, the general shape of a tapered ellipse around said tubular bodies.
  • This base 6 formed of a wafer 7 allows good bonding of the walls of the pocket 1, that is to say the crushing of the walls of the pocket against each other, at the connector 3, when emptying the pocket.
  • a good collabage thus optimizes the complete emptying of the bag during an infusion to a patient.
  • Thicker or hollow bases prevent the walls from collapsing at the connector, thus creating a retention zone of the fluid contained in the pocket.
  • the wafer 7 comprises a welding zone 8 intended to be welded to the walls of an infusion bag and a gripping zone 9 which extends outside said welding zone between the first and second tubular bodies 4, 5, said gripping zone 9 having a size and rigidity sufficient to allow gripping.
  • the welding zone 8 corresponds to the area of the wafer 7 which will be placed between the walls of the infusion bag. As illustrated on the figure 2 this welding zone is provided with welding ribs 10 in order to facilitate the welding of the walls of the pocket on the connector 3.
  • the welding ribs 10 are arranged over the entire length of the plate, perpendicular to the axis of the tubular bodies 4.5.
  • the thickness of the welding ribs 10 is of the order of 0.5 mm.
  • the number of welding ribs depends on the size of the welding zone 8 and the size of said ribs 10. On the figure 2 four welding ribs 10 are shown.
  • the thickness of the welding ribs 10 increases in the direction of the tubular bodies 4,5 thus having, in cross-section with respect to the axis of the tubular bodies 4 , 5, the general shape of a tapered ellipse around said bodies ( figure 4 ).
  • each transverse end of the wafer 7 forming the base 6 is extended by a tongue 11.
  • These tongues 11 have a reduced thickness relative to that of the wafer 7, for example of the order of 0.25 mm. These tongues 11 improve the welding of the walls of the infusion bag on the connector 3.
  • the gripping zone 9 of the wafer 7 extends the welding zone 8.
  • This gripping zone 9 is in particular full, that is to say that it does not have an aperture.
  • This gripping zone 9 allows a user to enter the pocket 1 between his fingers. During the manufacture of the pocket, this gripping zone 9 can also be grasped by a machine to automate the manufacture. In addition, this gripping zone 9 limits the fragility of the connector generated by the fineness of the base.
  • the gripping zone 9 is provided with gripping ribs 12. These gripping ribs 12 extend perpendicularly to the axis of the tubular bodies 4,5.
  • gripping ribs 12 for example four in number, have a thickness less than that of the welding ribs 10.
  • the gripping ribs 12 have a thickness of the order of 0.25 mm.
  • a reinforcing element 13 is arranged in the gripping zone 9 away from the welding zone 8 of the wafer 7.
  • This reinforcing element is positioned between the two tubular bodies 4, perpendicular to the axis of each of the tubular bodies 4,5. This positioning thus limits the deformation of the connector 3 in the plane defined by the axes of the tubular bodies.
  • the base 6 being formed of a plate 7, and therefore being substantially thin, it is fragile and can break or easily deform. The presence of this reinforcing element 13 increases the strength of the connector 3.
  • this reinforcing element 13 allows a machine to correctly and reproducibly position the connector 3 for its welding to the walls of the infusion bag.
  • the reinforcing element 13 is in the form of a reinforcing rib.
  • the reinforcing rib has a thickness of the order of 1.8 mm.
  • each of the faces of the plate 7 forming the base 6 comprises welding ribs 10, gripping ribs 12 and a reinforcing rib 13.
  • the connector comprises a first tubular body 4 and a second tubular body 5, each forming an access port to the inner volume of the pocket.
  • the first tubular body 4 in particular forming an infusion site, is equipped with a sleeve 14 having a perforable transverse partition 15 intended to seal the access orifice, a perforable shutter 16 arranged in a sealed manner on said transverse partition 15, and a cap 17 for compressing on the tubular body 4 said perforable shutter 16 mounted on said sleeve 14.
  • the sleeve comprises a flange 18 compressed on the edge of the first tubular body 4.
  • the sleeve 14 is formed of a substantially cylindrical element having at its downstream end the flange 18 directed outwardly of the sleeve 14.
  • the transverse wall 15 of the bushing 14 is located in particular in the downstream portion of said bushing 14, in particular at the downstream end.
  • the curved transverse partition extends outwardly of the bushing to form said flange 18.
  • This bushing 14 is mounted in force inside the first tubular body 4, the flange 18 of the bushing resting on the downstream end of said first tubular body 4.
  • the transverse partition 15 of the bushing 14 hermetically closes the first body tubular 4 so as to prevent, before perforation, the passage of the fluid contained in the pocket to the outside of said pocket.
  • the upstream portion of the bushing 14, before assembly in the first tubular body 4 is flared, that is to say that the upstream outside diameter of the bushing 14 is slightly greater than its downstream outside diameter.
  • the transverse partition 15 is perforable, in particular by a perforator 36 as shown in FIG. figure 11 , or by a cannula.
  • the transverse partition 15 is in the form of a thin wall, of the order of 0.25 mm, made of the same material as the cylindrical element of the sleeve 14.
  • the perforable shutter 16 is sealingly disposed on the transverse wall 15 of the socket, that is to say on the downstream side of the partition.
  • the transverse partition 15, before perforation also prevents the direct contact of the fluid contained in the infusion bag with the perforable shutter 16.
  • the perforable shutter 16 comprises a membrane of elastomer, rubber or other similar material, which can be traversed by a perforator and close by itself once the perforator has been removed.
  • the perforator is for example that of a perfusor.
  • the perforable shutter 16 has a substantially cylindrical body of relatively small height relative to the diameter.
  • the body has a shoulder bearing on the flange 18 of the sleeve 14 when the perforable shutter 16 is mounted in said sleeve.
  • the transverse wall 21 of the cap 17 compresses the perforable shutter 16 at this shoulder.
  • the central portion of the downstream surface of said body has a disk-shaped scar slightly curved towards the inside of the sleeve 14.
  • the upstream surface of said body is substantially curved.
  • the sleeve 14 and the perforable shutter 16 form a unitary piece.
  • the bushing 14 and the perforable shutter 16 are welded together in an inseparable manner.
  • the sleeve 14 and the perforable shutter 16 are formed by bi-injection molding,
  • the first tubular body 4 is also equipped with a cap 17 for compressing said perforable shutter 16 and said sleeve 14 on the tubular body 4. As shown in FIG. figure 3 , the cap 17 covers said first tubular body 4.
  • first tubular body 4 and the cap 17 have complementary latching projections 19,20, represented in particular on the figure 3 .
  • the cap 17 is formed of a transverse wall 21 extending into a peripheral skirt 22, visible on the figure 9 .
  • the transverse wall 21 crushes the perforable shutter 16 to keep it firmly clamped in said first tubular body 4.
  • the cap 17 has an opening 23 arranged to allow the introduction of a perforator into the shutter.
  • the opening 23 is arranged in the transverse wall 21 of the cap 17 as shown on the Figures 9 and 11 .
  • the surface of the transverse partition 15 of the sleeve 14 in contact with the perforable shutter 16 is curve so as to locally increase the compression of said perforable shutter 16 between said cap 17 and said tubular body 4, especially during the perforation.
  • the curved shape increases the compression of the part of the perforable shutter 16 which is arranged between the transverse wall 21 of the cap 17 and the flange 18 of the sleeve 14.
  • the shape of the transverse partition 15 is not straight, but curved, that is to say that the central zone of the transverse partition 15 is not at the same level as the peripheral zone of said transverse partition 15.
  • This curved shape of the transverse partition 15 in close contact with the perforable shutter 16 will increase the vertical stress exerted by the cap 17 on the perforable shutter 16 during placement of the cap 17 on the first tubular body 4.
  • the surface of said transverse partition 15 is curved towards the inside of the bushing 14, that is to say upstream.
  • the transverse septum 15 is convex when the infusion bag is used, i.e., when the bag is arranged for the fluid in the bag to flow from the inside of the outside.
  • the surface of said transverse partition 15 is curved outwardly of the sleeve 14, that is to say downstream.
  • the transverse septum is concave when the infusion bag is used, i.e., when the bag is disposed for the fluid in the bag to flow from the inside of the outside.
  • the surface of the perforable shutter 16 in contact with the transverse partition 15 has a curved complementary shape.
  • the surface of the perforable shutter 16 in contact with the cap 17 and in particular the transverse wall 21 of the cap 17 is flat.
  • the perforable shutter 16 is thus substantially plano-convex or plane-concave.
  • the seal between the cap 17 and the perforable shutter 16 is further increased when the sleeve 14 has a flared shape as defined above.
  • the connector 3 further comprises a plug 24 having a zone of weakness 25 associated with the cap 17, said zone of weakness 25 being arranged to be broken by a manual action so as to separate the plug 24 from said cap 17 and allow access to the opening of the cap 17.
  • the plug 24 protects the perforable shutter 16 until the user wishes to perforate said shutter by a perforator.
  • the zone of weakness 25 of the stopper 24 can be broken during a lateral or rotational load.
  • the first tubular body 4 is advantageously rigid in order to avoid being deformed or twisted when opening the stopper 24.
  • the plug 24 comprises a pallet 26 of shape and size sufficient for a user to grasp it between his fingers.
  • the zone of weakness 25 is broken by exerting a rotational movement or a lateral movement on this pallet 26, making accessible the opening 23 of the cap 17 and therefore the pierceable shutter 16.
  • the zone of weakness 25 is, for example, a zone of small thickness, for example of the order of 0.1 mm.
  • the first tubular body 4 has on its external surface a collar 27 with respect to which the cap 17 is disposed.
  • the cap 17 is locked in rotation on the tubular body 4.

  • These fins 28 engage in ridges 29 provided on the inner surface of the cap 17.
  • the number of ridges 29 is equal to or greater than the number of fins 28. A greater number of ridges 29 facilitate the mounting of the cap 17 on the tubular body 4.
  • the second tubular body 5 forming in particular an injection site, is equipped with a tip 30 and a perforable shutter 31 sealingly disposed in said tip 30.
  • the second tubular body 5 is advantageously flexible to allow manual or automatic clamping to control the introduction of an additive into the pocket.
