Sealing device

Abstract

The invention discloses a sealing device which comprises a body with a separable space. The separable space is divided into a first separable space and a second separable space by the body, a first body and a second body are arranged on the body, light-proof materials cover the outer side of the first body and / or are clamped on the first body, light-proof materials cover the outer side of the second body and / or are clamped on the second body, and a masker at least shielding one side of the gap among the light-proof materials on the first body and the light-proof materials on the second body and exceeding the spacing length of the gap is arranged at the gap. By the aid of separation materials, the sealing device solves the problem that expected shielding easy photolysis substances react with materials contacting with the substances to cause physicochemical property change of the easy photolysis substances. Stability of the easy photolysis substances is ensured, good light-proof property is kept by the aid of the masker, and the sealing device is used for the field of medical packaging materials.

Description

technical field [0001] The invention relates to the field of medical packaging materials, in particular to a sealing device. Background technique [0002] In daily life, it is often necessary to use light-proof materials to separate and store some special materials (such as light-decomposable drugs, reagents, formulations, and materials, etc.), infusion therapy, and transshipment. Clinically, some drugs have poor stability and are prone to reactions such as oxidation, decomposition, and discoloration when exposed to light after dissolution; some chemotherapeutic drugs may undergo complex reactions such as ring splitting, rearrangement, hydrolysis, polymerization, oxidation, and isomerization after dissolution. Light can catalyze the process of the above reaction. However, when the light-shielding material is in direct contact with light-decomposable substances, the physical and chemical properties of the drug or material are often affected or other chemical reactions occur....

AI Technical Summary

Problems solved by technology

Clinically, some drugs have poor stability and are prone to reactions such as oxidation, decomposition, and discoloration when exposed to light after dissolution; some chemotherapeutic drugs may undergo complex reactions such as ring splitting, rearrangement, hydrolysis, polymerization, oxidation, and isomerization after dissolution. Light can catalyze the process of the above reaction

However, when the light-shielding material is in direct contact with light-decomposable substances, it will often affect the physical and chemical properties of the drug or material or cause other chemical reactions.

[0003] There are gaps between the light-shielding materials in the current light-proof products, so that light can enter the inside of the light-proof products through the gaps, and the light-proof performance is reduced
