Description

Technical Field

[0001] The utility model relates to the technical field of light-proof bags for extension tubes, in particular to a light-proof bag for extension tubes. Background Art

[0002] As we all know, infusion, also known as intravenous drip or intravenous infusion, is a treatment method that delivers fluids into the body through the veins. Injecting medication into the body's blood vessels allows for large doses of medication, rapid results, and effective results. Infusion bottles are common medical supplies. Because the liquid within these bottles contains medication, it must be kept dry and sterile to ensure optimal efficacy. Some medications are susceptible to light degradation, so they often require a light-blocking bag (typically dark in color and made of a light-blocking material) to protect the bottle from light.

[0003] The existing light-proof infusion bag is not convenient for light-proofing extension tubes of different diameters during use, and is not convenient for light-proofing during use. Therefore, we propose a light-proof bag for extension tubes to solve the above problems. Utility Model Content
