A system for manufacturing medical solution bag

The present invention relates to a manufacturing system of a chemical liquid bag, which will be described in more detail in the manufacture of a medical solution bag, first preparing a pre-bag in which a port body is sealed on one side, and the port body. By injecting the chemical solution into the pre-bag through, and then inserting the closing cap on the top of the port body, the pre-bag manufacturing process and the chemical liquid injection process can be carried out continuously in one manufacturing facility, and also the pre- The present invention relates to a manufacturing system of a chemical liquid bag that can not only reduce manufacturing costs by installing a tube in the bag, but also greatly reduce a leak rate of leaking liquid from a finished product.

Various parenteral nutrition, peritoneal dialysis solution, and blood, which are administered to patients for therapeutic purposes, are stored in medical containers with certain material conditions. In the past, as a medical container, a glass bottle was mainly used, but recently, a plastic bag made of Non-PVC, which is easy to store and handle, has been widely used. Such a product that preserves a chemical solution used for therapeutic purposes in a plastic bag is called a 'medical solution bag'.

The manufacturing process of the chemical liquid bag can be roughly divided into a bag sealing process and a chemical liquid filling process. In the bag sealing process, two layers of synthetic resin sheets (Sheet) are fused and cut in a predetermined shape to prepare a pre-bag having an accommodating space therein, that is, a chamber. At this time, a plastic tube for injecting the chemical into the chamber is installed at the periphery of the pre-bag, that is, the sealing portion.

Next, in the chemical liquid filling process, the chemical liquid is injected into the bag through the tube, and then the port is inserted into the tube to finally complete the chemical liquid bag. The port is usually composed of a cylindrical port body having a lower end inserted into the tube and a rubber stopper and a closing cap installed thereon. Thus, when using the medicine bag, after removing the closing cap installed on the top of the port body, and inserting a syringe for injection or drainage (Spike) into the rubber stopper.

As described above, in the conventional chemical liquid bag manufacturing method, a free bag having a tube installed on one side thereof is first manufactured, and the chemical liquid is filled into the free bag through the tube, and then a port is inserted into the tube to be sealed again. As a result, the overall manufacturing process is complicated, and in particular, leakage defects in the finished product are frequently caused by poor sealing of the tube.

Also, in the related art, the bag sealing process and the chemical liquid filling process are generally performed in independent production lines. This is because the sealing process is performed while the sheet and the pre-back are horizontally laid down, and in the filling process, the pre-back is vertically formed, that is, the tube is raised. The overall manufacturing equipment is complex, there is a disadvantage that requires a lot of space for such a manufacturing equipment.

Accordingly, the problem to be solved by the present invention is that in the preparation of the chemical liquid bag, the pre-bag manufacturing process and the chemical liquid filling process are continuously performed in one manufacturing facility, so that the overall manufacturing equipment is simple, and in particular, the tube is not installed in the pre-bag. By directly installing the port body, it is possible to greatly reduce the manufacturing cost, and further provide a new chemical liquid bag manufacturing system that can structurally significantly reduce the leakage of the finished product.

In order to solve the above problems, the method for manufacturing a chemical liquid bag according to the present invention includes a double-ply synthetic resin sheet and a hollow housing having a large diameter cap housing formed at the upper side with a boundary between the intermediate steps and a lower diameter at the lower side thereof.
