Description

  The present invention relates to a medical tube kit for medical solutions, and more particularly, to a medical tube kit that uses a container that is easy to hold and is highly convenient for adjusting the concentration of a medical solution with high accuracy.

  In general, medical nutrients used for Crohn's disease patients, liver failure patients, and the like are prepared by dissolving a nutrient component powder in water at the time of use. Preparation methods include a method of preparing a predetermined amount of nutrient component powder and a predetermined amount of water measured in advance in a container, or a predetermined amount in a container equipped with a liquid level display scale. A method of preparing a predetermined amount of water by using a liquid quantity display scale after putting a nutrient component powder is used. The container for preparation used at the time of preparation may be a container separate from the container for administration used for administration of nutrients, and may also serve as a container for administration in order to prevent contamination during preparation and for convenience. is there. The prepared concentration is generally adjusted to a standard concentration determined in advance, but at the start of administration, it is adjusted to a concentration lower than the standard concentration, and the concentration is gradually increased in consideration of the patient's condition. Standard concentration is reached. The prepared nutrient is administered orally or by tube.

In addition, as a container for a medical nutrient, a container made of polyethylene or polypropylene has been generally used. Polypropylene, which requires only a small amount of plasticizer during molding, is highly safe against elution from the container to the stored items, and is widely used as a medical container for storing liquid items.
Polypropylene is widely used as a packaging material for food, stationery, and the like because it is low in cost, excellent in mechanical strength and heat resistance, and easy to recycle. However, the use of polypropylene is limited because of its poor transparency (see, for example, Patent Document 1). In addition, polypropylene has a low tensile elastic modulus and bending elastic modulus and is inferior in rigidity.

Conventional nutrient containers are made of polypropylene, so the transparency is low, and it is difficult to confirm the amount of liquid in the container and the degree of dissolution when the nutrient ingredient powder is dissolved in water. Met.
Further, since a conventional container for nutrients is made of polypropylene, it has a low tensile elastic modulus and bending elastic modulus and is easily deformed by the force applied from the hand when the container is held. For this reason, the conventional containers for nutrients lacked a sense of stability when held in their hands and were difficult to hold. In addition, the conventional container for nutrients must have enough space for the nutrients at the top of the container so that the nutrients do not overflow due to deformation of the container when it is held in the hand. It was.

  Moreover, since the liquid quantity display scale provided in the container for conventional nutrients is provided in plurality in order to display the liquid quantity in a container, the water at the time of preparation using a liquid quantity display scale is used. When measuring the amount of nutrients, it was necessary for the operator to find out which scale should be used corresponding to the amount of the nutrient component powder and the preparation concentration, and the workability was poor. . Furthermore, conventional containers for nutrients have a large concentration error due to the ease of deformation of the container and the low transparency, when the amount of water during preparation is measured using a scale.

  The present invention has been made in view of the above circumstances, has high transparency and rigidity, and it is easy to check the amount of liquid in the container and the degree of dissolution when the powder is dissolved in water. An object of the present invention is to provide an easy-to-use tube kit equipped with a container that can easily adjust the concentration of a medical solution with high accuracy.

  In order to achieve the above object, the tube kit of the present invention is a container made of polyethylene terephthalate for a medical solution prepared by dissolving a predetermined amount of powder in a predetermined amount of water at the time of use.
