Medical container

Abstract

[Problem] To lengthen the storage period of a medical substance enclosed inside a medical container. [Solution] A hydrogen-generating substance which produces hydrogen by reacting with moisture (water or water vapour) in a medical substance or moisture in mixed air is kneaded into an exterior sheet (40) of a medical container (10 (20, 30)) in which a medical substance is enclosed. A suitable bag-shaped medical container ((10) of fig. 1), tube-shaped medical container ((20) of fig. 2), or medical container ((30) of fig. 3) equipped with a sealing fastener (31), or the like can be used as an embodiment of the medical container. The medical substance containing moisture can, for example, be blood, an injection solution, a drug solution, a nutrient solution, a fluid replacement solution (infusion solution), a drip infusion solution, or the like. A solid preparation is preferably enclosed inside the medical container (30) having the sealing fastener (31). Magnesium metal, for example, can be used as the hydrogen-generating substance to be kneaded, and in particular, it is preferable to use a fine powder of a ceramic formed by firing a mixture of mineral substances such as calcium.

Description

technical field [0001] The present invention relates to a medical container used for enclosing blood and the like in advance. Background technique [0002] Various medical substances such as blood, injections, and various infusions are supplied to medical practitioners such as doctors in a state sealed in airtight containers in advance (see Patent Document 1 disclosing a blood bag). [0003] In the case of a liquid medical substance such as blood, it is usually enclosed in a bag-shaped medical container. In addition, medicines for external use typically represented by ointments are often enclosed in tube-shaped medical containers. Furthermore, in the case of a solid preparation, it is often enclosed in a medical container that can be opened and closed by a sealing clip and can be sealed. [0004] The purpose of enclosing medical substances in medical containers in advance is to maintain a sterilized or reduced-bacteria state by isolating them from outside air, and at the s...

AI Technical Summary

Problems solved by technology

[0015] Even if the medical substance is enclosed in the medical container as above, a lot of air will be mixed into the medical container during the sealing, so the deterioration (oxidation) caused by the oxygen in the air cannot be avoided by any means.

Especially in medical containers of the type that are opened and closed by sealing clips, air re-enters from the outside every time they are opened and closed, which further promotes deterioration

[0016] In particular, medical substances are highly necessary to be stored in large quantities as stocks in advance for emergencies and disasters, and long-term storage is required, but long-term storage is difficult due to deterioration caused by oxygen in the air
