Description

TECHNICAL FIELD

[0001] The utility model relates to the field of grid frame, especially a telescopic grid frame. BACKGROUND

[0002] Medical paper-plastic bags are widely used in the sterilization packaging of medical instruments and articles, and have good air permeability, antibacterial properties, and visibility, making them suitable for various sterilization methods such as ethylene oxide sterilization, high-temperature steam sterilization, and hydrogen peroxide low-temperature sterilization. Here are some common instruments and articles that can be packaged using medical paper-plastic bags:

[0003] 1. Medical instruments

[0004] (1) Light and medium weight instruments: such as surgical scissors, forceps, hemostatic forceps, dental instruments, etc.

[0005] (2) Disposable instruments: such as syringes, catheters, probes, indwelling needles, and electric scalpel pens.

[0006] (3) Precision instruments: such as endoscope accessories and microsurgical instruments, which require good protection and visibility.

[0007] (4) Small medical instruments: such as medical forceps, surgical blades, and suture needles.

[0008] 2. Medical supplies and articles

[0009] Dressing materials: such as gauze, hemostatic gauze, surgical drape, and dressing tape.

[0010] When paper-plastic bags are used to package surgical instruments and articles, the paper-plastic bags are medical-grade and have high-temperature resistance. During sterilization, the paper-plastic bags are placed in a special instrument basket and then put into a sterilizer. This structure causes the packaging bags to stack on the special instrument basket, reducing the penetration of sterilization media and the effectiveness of wet-pack sterilization during low-temperature sterilization or pressure steam sterilization.
