Needle core of the anesthetic syringe.
The core of this anesthetic needle meets the specifications for producing a product with a thin section of φ0.6 and 125mm, with a withdrawal taper of 0 degrees.
Generally, the mainstream in the industry is to attach a cap to a thin metal pin for the anesthetic needle core, but this anesthetic needle core is a one-piece molded product. We have achieved the production of a product that meets the specifications requiring a withdrawal taper of 0 degrees for the thin part with a diameter of 0.6 mm and a length of 125 mm, and prohibits particle lines (PL), split lines, and voids. There are many types of needle core lengths, and since the tip part is cut to match the needle length, it cannot be used if there are voids on the cut surface. Additionally, the advantages of a one-piece molded product include: 1. Safety (with metal anesthetic needle cores, there was a risk of accidentally stabbing the nurse's hand during handling, leading to infection, but plastic is soft and does not stab, making it safe) 2. Usable for patients with metal allergies (with a metal core, there was a slight generation of metal powder due to friction inside the needle, but using plastic eliminates this issue) 3. Easy disposal (since it is all plastic, it can be processed collectively) 4. Cost reduction (the raw material cost is lower than metal, and there is no adhesive process)
