Definitions

  • the present invention relates to an arrangement for infusion bags such as are executed from double Layers of a soft, flexible film and which exhibit at Least two separate chambers formed between the Layers of film by being joined together in areas around the chambers, said chambers being provided with connections through which an infusion liquid, intended to be enclosed inside the chambers, can be removed by means of a tubular organ, preferably a cannula, passing through the connection, whereby the intention is that the chambers shall be emptied in a pre-determined sequence.
  • the container is in the form of a plastic film bag.
  • a bag of such a kind must be provided with a connection point to which the tube can be connected.
  • the intention is that a number of infusion liquids shall be administered in a pre-determined sequence and in specific proportions. This can be achieved, of course, by supplying the different Liquids in separate containers, which are connected in turn so as to permit each substance to be introduced into the body.
  • the object of the present invention is to propose an arrangement for infusion bags which wiLL prevent the substances from being administered in the wrong sequence, thereby eliminating the aforementioned mistakes and preventing damage.
  • the object of the invention is achieved by executing the arrangement for infusion bags in such a way that the connection to the chamber which is intended to be emptied first is directly accessible for the introduction of said organ , whilst the connection to the chamber which is intended to be emptied next is Located inside the first chamber in such a way that the first chamber in a full and distended state wiLL prevent direct access by the organ to the connection.
  • Fig. 1 shows the first embodiment in front view
  • Fig. 2 shows the second embodiment in front view
  • Fig. 3 shows the first embodiment as a section along the line III-III in Fig. 1
  • Fig. 4 shows the second embodiment in a (shortened) section aLong the Line IV-IV in Fig. 2.
  • Both embodiments relate to infusion bags comprising two pieces of plastic film welded together and with plastic components welded into them.
  • PreviousLy disclosed is a method of executing infusion bags in this manner, usuaLLy making use of vinyl plastic which is easily welded together by the use of a high-frequency electrical field. Consequently, the method will not be described in any greater detail here.
  • the bags are essentially identical in both embodiments, and the immediately following part of the specification including the reference designations relates to both embodiments.
  • the bag is formed from two pieces of plastic film 1 and 2 which are joined together by means of welded areas around the edges.
  • the welded area along the side edges is designated by the number 3 .
  • On an upper, wide welded area 4 are omitted for manufacturing reasons certain unwelded areas 5 and in a similar fashion two unwelded parts 7 have been omitted from a wide, Lower welded area 6 .
  • the unwelded areas 5, 7 are not, however, essential to the function of the bag, but have been introduced for manufacturing reasons.
  • two holes 8 which can be used for hanging up the bag during infusion.
  • the bag extends between the upper welded area 4 and one of the side edges 3 an angular welded area 9 .
  • the bag is divided up into two chambers in which the plastic films 1 and 2 are not connected to each other. These chambers are on the one hand a first chamber. 10 which extends together with a transverse Lower part 11 over the bag and includes additionally a rising part 12 , and on the other hand a second chamber 13 which is essentially rectangular.
  • the first chamber 10 is provided in the middle of the welded area 6 with a connection 14 which is formed from a projecting part of the two pieces of plastic film, along the edge of which the films are welded together in a narrow welded area 15 .
  • the welded area 6 is interrupted directly in Line with the connection 14 , so as to form a passageway 16 .
  • connection 17 which consists of a plastic component 18 welded into the welded area 9 .
  • the inner edges of the welded fields 6 and 9 are inclined towards.the respective connections 14 and 17 so that drainage surfaces running downwards towards the connectors are formed when the bag is suspended by its holes 8 .
  • the plastic component 19 connects to the first chamber and the plastic component 20 to the second chamber.
  • the two plastic components have a tubular shape and exhibit a passage 21, which is open inwards towards the respective chamber 10, 13 but which is outwards closed by a base 22.
  • This base is intended to be penetrated by means of a cannula if any medicine is intended to be brought into any of the chambers.
  • a rubber elastic plastic preferably vinyl plastic, is used for the plastic components, penetration will be possible at the same time as the hole is sealed by means of the elasticity of the material after the withdrawal of the cannula.
  • Figs. 3 and 4 the plastic films 1 are shown to be well separated in those parts where they are not welded together or welded securely to the plastic. components 18, 20 .
  • the state illustrated corresponds approximately to the state of the bag when it is full, although no Liquid is shown in Figs. 3 and 4 in order to make the Figures more clear.
  • the bag Since the bag is to be supplied containing two sorts of infusion liquid, it is necessary to provide two filling openings. These are welded up after filling and accordingly are of no significance to the function of the present arrangement. It must be pointed out, however, that the plastic components 19, 20 may be so executed that they are open in an outwa'rd sense after the welding of the bag, so that filling may take place after which they are closed for instance by welding up the bases 22 .
  • the plastic films 1 and 2 are separate from each other for the entire distance between the connections 14 and 17 , and also over the entire width of the component 11 of the chamber 10 .
  • a further welded area 23 which is isolated from the other welded areas and extends straight across the Line between the two connections 14 and 17 a short distance away from the plastic component 18 .
  • the bag in accordance with this embodiment is provided with a tear-off Line 24 which extends along the middle of the angular welded area 9 and out to the edge of the bag.
  • the bag When the bag is supplied ready for use, it is as already stated filled with two infusion Liquids. These Liquids are to be administered to the body in a specified sequence, and the Liquid which is to be administered first is present in the first chamber 10 , and the infusion Liquid which is to be administered next is present in the chamber 13 . It is assumed in this respect that at least the chamber 10 will be sufficiently well-filled for the plastic films to be distended away from each other, thereby preventing them from being forced together to any appreciable degree.
  • connection 14 When infusion is to begin, the connection 14 is penetrated by means of a cannula which is introduced into the duct 16 and which thus makes a connection with the chamber 10 .
  • the width of the part 11 of the chamber 10 is selected in such a way that the length of the infusion needle is insufficient for its tip to reach the far wall of the chamber 10 and thus the welded area 9 and the connection 17 when the shoulder of the cannula comes up against the outer part of the connection 14 . Since the body formed by the pieces of plastic film distended by the Liquid cannot be compressed to any appreciable degree for so Long as the bag is full, this will ensure that the cannula will be connected only to the first chamber 10 .
  • infusion cannulae are of a standardized Length which practicaLLy excludes any possibility of initiating the infusion operation by introducing the cannula into the wrong chamber.
  • the infusion operation is continued by starting to administer the Liquid contained in the chamber 13 .
  • the chamber 10 Once the chamber 10 is empty, there will no Longer be any resistance to advancing the cannula. It may now be moved upwards and introduced through the base of the plastic component 18 into the chamber 13 . The plastic film in the part 11 will now fold ahead of the shoulder of the cannula.
  • the embodiment in accordance with Figs. 2 and 4 will offer additional protection against the premature connection of the chamber 13 . It is, in fact, necessary in this case, before connection can be made to the second chamber 13 , for the even more positive act to be performed of tearing off that part which contains the chamber 10 by tearing along the tear-off Line 24 .
  • the welded area 23 will, in fact, prevent the tip of the cannula from being pushed up as far as the connection 17 for so Long as the bag remains intact.
  • the underlying idea behind the invention is thus that the first chamber which is to be emptied shall be positioned ahead of the connection to the next chamber to be emptied. This requires the design and the degree of filling in the delivery state to be such that penetration of the connection for the second chamber will be prevented when the bag is full.
  • the design of the chambers may differ within the scope of this principle, and the holding capacities of the chambers must, of course, agree with the desired quantities of the different infusion Liquids to be administered. It is also possible to apply this principle to a greater number of infusion Liquids than two, whereby the different chambers are arranged one ahead of the other in sequence depending on the point at which they are to be used for the purpose of administering the infusion.
