Surgical drainage bag ports connect drainage tubes and storage bags, requiring leak-proof, biocompatible and flexible connection, adapting to clinical drainage operation and patient movement, prohibiting fluid leakage and bacterial intrusion. Traditional heat sealing has poor firmness, easy cracking during pulling, while adhesive bonding has poor biocompatibility, easy to cause tissue irritation. DaokeDao laser welding provides a reliable sealing scheme for medical-grade PE and PP materials, forming a flexible and tough weld, with strong pull resistance (≥15N), not easy to crack or fall off during patient turning and movement. The weld is smooth and burr-free, no damage to drainage tubes, ensuring smooth fluid flow. The entire process is particle-free and clean, complying with medical device production cleanliness standards, no chemical residues, fully meeting clinical biocompatibility requirements. The equipment supports automated continuous production, with stable welding quality, no need for post-processing, directly entering sterilization packaging. Compared with traditional processes, it reduces leakage risk by 90%, improves product safety, helps medical consumable manufacturers meet clinical use needs, and reduces patient infection risks.
