Abstract
Abstract Arrangement for infusion bags such as are executed from double layers of a soft, flexible film. Two separate chambers (10, 13) are formed between the films by joining these together in areas (3, 4, 6) around the chambers. The chambers are provided with connections (14, 17) via which an infusion liquid can be removed by means of a tubular organ passing through the connection. The intention is that the chambers shall be emptied in a pre-determined sequence. The connection (14) to the chamber (10) which is intended to be emptied first is directly accessible for the introduction of said organ. The connection (17) to the chamber (13) 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 (17).

Arrangement in accordance with Patent CLaim 1 in which the infusion bag is so arranged as to exhibit a number of chambers greater than two, characterized in that each chamber is so arranged that, when it is in its full and distended state, it will cover the connection of the chamber immediately following in the emptying sequence so that, when said first chamber is in its full and distended state, said connection will not be directly accessible to the organ.
Claim 4
Dependent Claim
70 words
Arrangement in accordance with Patent CLaims 1 or 2, characterized in that the connection (17) to a subsequent chamber (13) which is intended to be emptied after an immediately preceding chamber (10) in the emptying sequence can be made accessible for the introduction of the organ by compressing the film material of the last-mentioned chamber after it has been emptied so as to permit the organ to be inserted further.
Claim 5
Dependent Claim
97 words
Arrangement in accordance with Patent Claims 1 or 2, characterized in that inside the one or more chambers (10) which are intended to be emptied before the following chamber (13) are arranged blocking elements (23) to prevent the introduction of the organ through the chamber as far as the connection (17) of the following chamber, whereby that part which forms the preceding chamber (10) is so arranged as to be torn off after the emptying of the chamber in question, so that the connection (17) of the following chamber (13) is made directly accessible to the organ.
