[0002] Medical cable ties are a type of consumable material used in many medical processes such as blood drawing, hemostasis, and infusion. They have a very wide range of applications. Traditional medical cable ties are generally rubber tubes or rubber strips. When in use, medical staff tie the medical cable ties with rubber tubes or rubber strips around the patient's arm to compress the blood vessels, thereby stopping bleeding or making the blood vessels stand out.

[0003] In the existing medical field, in order to reduce the risk of infection, most hospitals have switched to disposable medical rolled tape for binding. However, with the increase in demand, the production efficiency of disposable medical rolled tape has gradually failed to keep up with the consumption rate. In the production process of medical rolled tape, bundles of medical rolled tape are usually required to be bundled with rubber bands to facilitate subsequent packaging and delivery. However, in the existing production process of disposable medical rolled tape, manual binding is usually required. The manual binding method is not only inefficient, but also easy to cause fatigue. Therefore, a device that can achieve automatic binding is needed. Utility Model Content
