Incision protective sleeve welding machine / PE incision protectors welding machine / PU notch protection heat sealing machine works: Each head of electric heating power is 500 watts, a total of 2000 watts. Fixed displacement protector cutout pellicle layer and a heater driven by cylinder, so that both ends of the protector cutout layer and the surface protective film is heated with a heater heating portion surface contact area to the surface melting, and then heated rapid surface bonding, curing to form one. These moving parts with a cutout layer protector feeding mechanism, clamping manipulator, a heater raising and lowering mechanism, the pressing means, these means into the machine design combinations. Bodies are made to push the cylinder. According to the new welding process requires plastic welding machine, the device uses the programmable controller (PLC), the automatic control system touch screen interface operation, simple, accurate, and reliable. Incision protective sleeve welding machine / PE incision protectors welding machine / PU notch protection heat sealing machine features: (1) having an electronic easing and electronic limit for implants, riveting and other hot-melt (2) hydraulic buffer and buffer circuit combined operation is very smooth (3) School of large objects for processing and multi-point simultaneous welding (4) the use of multi-stage heat pipe and imported temperature control system, temperature control is accurate and reliable (5) using electrostatic spraying and plated chrome and other surface treatments, beautiful appearance, durable protective cover cuts welding machine / PE incision protectors welding machine / PU notch protection welding machine production methods: plastic ring inner diameter respectively 18,22,26cm, around the diameter of the plastic film 40cm, viscose 4 (FIG. 1). Use conventional exploration into the abdomen, choose the right type of sterile incision layer protection, the plastic ring and plastic film after wet lubrication handed surgery, hand surgery compressed circular plastic ring into an oval, the first end of the plug into the abdominal cavity, and then the other end into the abdominal cavity, either adhesive tape around it to expand and to tear strips fixed to laparotomy list. Incision layer protection into use after the incineration of medical garbage bag. Incision protective sleeve welding machine / PE incision protectors welding machine / PU notch protection welding machine advantages: (1) the cut disposable layer protection, when used according to the size of the selection incision layer protection (plastic ring) incision of size; (2) maximize the isolation ascites, blood, avoiding its exudation wet towel, to avoid contamination; (3) help clean and dry the operating table, reducing the nurses because ascites, blood wet towel constantly changing linen brought workload; (4) the cut edges to prevent cancer cells grow peritoneal tumor resection; (5) Simple, one person can operate; (6) one-time use is simple, according to the dirt after incineration ; (7) abdominal incision can be used, should be widely applied.
