However, in this case, since the internal pressure in the bag body is excessively increased by the heat of the filled liquid, when the nozzle is pulled out from the mouth of the bag body after the liquid is filled, the liquid may flow back from the mouth and spray. out, the target liquid amount cannot be filled reliably
In addition, if an on-site operator such as a medical bag manufacturing factory touches a medical bag filled with a high-temperature liquid, the worker may be burned, or when a plurality of medical bags are stacked for sterilization, the relevant Adhesion (similar to welding) may occur between the surface of one medical bag and the surface of the other medical bag between two adjacent medical bags

Embodiment Construction
[0066] Hereinafter, the method of manufacturing the medical bag and the medical bag of the present invention will be described in detail based on preferred embodiments shown in the drawings.
[0067] Figure 1 to Figure 9 Each is a schematic perspective view sequentially showing each step in the manufacturing method of the medical bag of the present invention. In addition, in the following, for the convenience of explanation, the Figure 1 to Figure 9 The right side is called "basal end", the left side is called "front end", the upper side is called "upper" or "upper", and the lower side is called "lower" or "below".
[0068] pass Figure 1 to Figure 9The medical bag 1 manufactured by the manufacturing method of the medical bag shown is equipped with the bag main body 2 and the port member (2nd mouth part) 3. In addition, the medical bag 1 may be a multi-chamber container in which the inside of the bag main body 2 is divided into a plurality of spaces, or may be a single-ch...

PROBLEM TO BE SOLVED: To provide a method for manufacturing a medical bag, which can easily and unfailingly fill a liquid into a bag body in manufacturing a medical bag filled with the liquid, and safely performing the manufacture; and to provide the medical bag manufactured by this method for manufacturing the medical bag. SOLUTION: The method for manufacturing a medical bag includes: filling a first liquid 11 and a second liquid into a soft bag body 2, formed like a bag and storable of the first and second liquids. This method is characterized in that before filling each of the liquids into the soft bag body 2, the liquids are heated up to 25-50°C in advance and filled so that the soft bag body 2 can be softened.
Description
technical field [0001] The present invention relates to a method for manufacturing a medical bag and the medical bag. Background technique [0002] As a medical bag, a medical bag is known in which a liquid such as an infusion solution or a peritoneal dialysis solution is sealed inside by welding a resin sheet (for example, see Patent Document 1). To manufacture such a medical bag, a nozzle can be inserted into the mouth of the pouch-shaped bag body made of the above-mentioned resin sheet, and the bag body can be filled with a liquid from the nozzle to manufacture it. At this time, when the above-mentioned resin sheet is composed of a material such as polypropylene as the main component, the liquid is heated to a relatively high temperature (for example, 50 to 55 degrees) in advance when the liquid is filled, and the liquid is heated before the liquid is not cooled. its filling. The reason for filling the high-temperature liquid is, for example, that the bag main body tend...
