Problems solved by technology

[0005] However, in the medical field in recent years, due to the heavy burden on the medical staff, the medical staff sometimes forgets the communication process between the storage parts of the multi-chamber container, and there is a possibility that only the multiple medicines stored in the multi-chamber container are mistakenly stored. The problem of medical malpractice such as administering part of the drug to the patient, or administering the drug to the patient before it is fully mixed

Embodiment 1

[0137] As Example 1, the medical multi-chamber container shown in the column of Example 1 in Table 1 below was produced in the following procedure.

[0138] First, the above-mentioned two 4-layer films are superimposed so that the inner layers of each 4-layer film are opposed to each other, and the simplified body of the discharge port 27 is sandwiched in the formation part of the discharge-side weak seal portion 18. Heat sealing, whereby the peripheral strong seal 26 is formed. The width of the peripheral strong seal portion 26 is approximately 8 mm in the width direction 15 in the side strong seal portion 16 , and is 10 mm or more in the discharge direction 14 in other portions.

[0139]Then, from the cylindrical body of the discharge port 27, after injecting physiological saline into the forming part of the second housing part 12 (the inner dimension of the discharge direction 14 is about 130 mm, and the inner dimension of the width direction 15 is about 100 mm), the four l...

Abstract

Provided is a method of a weak sealing part through simply processing the medical multichamber container, comprising a multichamber container manufacturing procedure and a strengthening procedure of the weak sealing part for manufacturing the medical multichamber container (10), which comprises a first holding part (11) for holding medicament, a second holding part (12) for holding medical solution, an empty holding part (13), a pair of side strong sealing part (16) forming two side parts of each holding part, a medical solution side weak sealing part (17) forming the bulkhead between the first holding part (11) and the second holding part (12), a discharge side weak sealing part (18) forming the bulkhead between the first holding part (11) and the empty holding part (13); a strengtheningfilm (20) for adhibiting and strengthening a discharge side sealing part (18) in the way of covering the surface of the first holding part (11) in the weak sealing part strengthening procedure and inthe way of partitioning the interval from a first bouderline margin (19) to the discharging direction in the discharge side sealing part (18).

Description

technical field [0001] The present invention relates to a method for reinforcing a weak seal portion in a multi-chamber medical container for accommodating a plurality of medicines that are mixed during use in each storage portion in an unmixed state. Background technique [0002] In drugs administered to patients by intravenous injection, for example, such as a combination of amino acid infusion and glucose infusion, a combination of fat emulsion and electrolyte solution, a combination of phosphoric acid-containing liquid and calcium-containing liquid, etc., if mixed with each other However, some combinations may decompose, discolor, coagulate, precipitate, etc. due to the interaction between agents. [0003] Also, for example, among medicines supplied as solid preparations, such as antibiotics, if stored in a state of being dissolved in a solution such as physiological saline in advance, some medicines may be decomposed, discolored or otherwise deteriorated. [0004] Ther...
