Abstract

PURPOSE:To eliminate possibility of leakage of a medicinal solution between chambers during the transportation or storage thereof by employing a connector part with a peeling strength of 300-800g/15mm in interface at a part of a multilayered film. CONSTITUTION:Peeling strength is set at 300-800g/15mm in an interface between layers A and B among those of a multilayered film. The multilayered film is sandwiched between two sheets of bag film as shown by Fig. 2 and the two sheets of bag film are fused intensely on the layers A and C of the multilayered film to form a boundary part for separating one bag into two chambers. Here, it is necessary to seal up both ends of the multilayered film in such a manner as to be extruded into the chambers from a sealing line at the heat sealing of the bag films. When two liquids are mixed together, the multilayered film is stimulated from outside the bag or the heat sealed part is distorted from outside, thereby enabling peeling off with relative ease.

[Prior Art 1] Recently, medical liquid containers, especially flexible soft bags, have been increasingly used due to their safety and ease of use. Conventionally, the two liquids were combined in a Y-tube just before use and dripped, but for reasons of handling and safety, the two liquids were placed in separate chambers in one bag. There is a strong demand for a medical bag having two or multiple chambers in which two liquids can be easily mixed and used in an integrated manner immediately before use. However, methods for separating two liquids in the same bag include holding the bag from the outside with a clamp or the like to separate the bag (making it into two chambers), or fusing the bag into two chambers and separating them. Attach the connector to the
The main method used has been to open the connector and mix the two liquids during use.

Each method has its advantages and disadvantages, and the method of clamping from the outside of the bag has the risk that if the clamp loosens for some reason, the two liquids will mix little by little without your knowledge. However, in the clamp method, the two liquids can be easily mixed by removing the clamp, and at the same time, by widening the clamp, it is possible to mix the two liquids in a short time, which is convenient.

On the other hand, in the method of separating the bag into two chambers by attaching the connector by welding, the bag is fused together with the connector, so unlike the previous clamp method, 2M can be easily mixed as long as the connector does not come off. It was difficult to imagine that this would happen, and therefore it was safe for long-term storage. However, in this method, the passage for mixing the two liquids is only in a part of the connector, and it is greatly influenced by the performance of this connector. In particular, since the two liquids are mixed by passing through this connector, it takes more time to mix than the clamp method, and depending on the type of connector, if this part is broken and connected, pieces of the connector may get mixed into the liquid. There was a problem.

The present inventors have discovered that the above-mentioned problems can be solved by a multi-chamber medical bag characterized by being fused to a bag film through a multilayer film having a strength of m■, and have completed the present invention.

At this time, as shown in FIGS. 2 and 3, it is necessary to seal both ends of the multilayer film so that they protrude into each chamber from the seal line during heat sealing with the bag film. Without this protruding portion, separation would easily occur between layer A and layer B when the internal pressure of the liquid in chamber P or chamber Q increases. However, if this protruding portion is 10 or more, even if internal pressure is applied to each chamber, stress will be concentrated at the seal line between the bag film and the multilayer film, so peeling will not occur between A and 8 of the multilayer film. It can exhibit excellent separation performance.

On the other hand, when the two liquids are mixed, the multilayer film can be peeled off relatively easily by applying stimulation to the multilayer film from outside the bag or by applying strain to the heat-sealed portion from the outside.
