Description

  The present invention relates to a packaging bag for storing a chemical solution. It is related with the packaging bag for chemical | medical solutions which can be especially connected between packaging bags.

  Conventionally, a liquid medicine packaging bag has a flexible packaging bag having a sealant layer on its inner surface sealed at the peripheral edge thereof, one end of a flexible packaging bag suspended from a suspension pole, and a liquid medicine administration tube attached to a spout provided at a lower end. It is widely known to connect and administer a drug solution into the body through the tube.

  However, the amount of chemicals used varies from day to day, such as for doctors, adults, children, the elderly, men and women, physiques, etc. To do. Therefore, complicated operations such as frequent replacement of packaging bags and replacement of tubes for drug administration have become normal. In addition, even with the same type of chemical solution, a plurality of packaging bags with different amounts of the chemical solution are held, and there is a problem that efficiency is poor in terms of storage management and storage location. In addition, there is a problem that the working hours per person increases at night and on weekends when the required number of doctors and nurses is not secured, increasing the risk of accidents.

  In the conventional chemical solution packaging bag, when preparing a necessary amount of chemical solution, it is necessary to prepare packaging bags of several types of chemical solutions. However, when packaging bags are prepared for different amounts of chemicals, many storage locations are required, and inventory management becomes difficult.

  In order to improve the work of doctors and nurses, in order to make it easy to use the packaging bag for chemicals, put a cap on the cylinder part of the spout, fit the tip part of the cylinder part and the cap, and break by turning the cap, There is a proposal of a method for opening the tube tip (Patent Document 1).

  This proposal is a proposal that can be made with a cap without using a means such as a bag and omits complicated work. It also has the effect of preventing leakage from the spout. However, it does not improve the adjustment of the amount of chemicals used.

  In addition, there is a packaging bag for chemical liquids provided with a spout storage part for storing the spout in the bag so that it does not come in contact with the outside air until it is used after filling the packaging bag in which the spout is protruding (Patent Document) 2).

  After filling the chemical, it is sterilized by retort. In use, it is a proposal to open the spout container and to take out the spout and connect it to a drug solution administration tube. Although it is good in terms of hygiene, it does not improve the adjustment of the amount of chemicals used.

  Hereinafter, modes for carrying out the present invention will be described.

  FIG. 1 is an explanatory view showing an example of a medical solution packaging bag 1 of the present invention. The periphery of the two laminated films on the front and back sides is sealed to form a packaging bag (the seal portion is indicated by 11). The extraction part 2 is arrange | positioned in a part of the packaging bag, and the connection part 3 is arrange | positioned in the opposing position of this extraction part. It has the 1st base part 4 connected with the sealant layer of a packaging bag, and the 1st base part 4 connected with the 2nd cylindrical part 7 of a connection part. Further, the connecting portion has a second base portion 5 that is heat-sealed with the sealant layer and a second cylindrical portion 7 that is connected to the first cylindrical portion 6.

  When attaching the extraction | pouring part 2 and the connection part 3 to a packaging bag, the 1st base 4 and the 2nd base 5 are heat-sealed with the sealant layer of a packaging bag. At this time, in order to facilitate heat fusion, for example, a thin boat-shaped heat fusion portion (not shown) is formed at both ends of each base portion, and it is securely attached by heat fusion. Can do. That is, it is attached to the packaging bag by sealing it into a boat shape. The base may be provided with a convex shape or a groove (not shown) in order to improve thermal fusion with the sheet layer.

  Moreover, the extraction | pouring part 2 and the connection part 3 are covered with the laminated | multilayer film which forms a packaging bag. The peripheral edge is sealed with a seal 11.

  A hole 8 for suspending from a part of the chemical packaging bag 1 is formed.
