Handbook of AS-E/S MiniⅠ 1． Product Introduction Tuoren AS-E/S MiniⅠ is a set for regional anesthesia. It provides the rapid onset and reliability of an epidural or spinal block, allowing anesthesia to be prolonged both intra and post-operatively. It can be used for combined anesthesia to realize intraoperative and postoperative patient-controlled analgesia. This product is designed for optimal performance, minimizing drag of needle and maximizing feeling of dural puncture. LOR indicator syringe facilitates confirmation of the correct needle tip position. 2． Intended use Used in epidural nerve block, subarachnoid nerve block to puncture or inject drug. 3． Components（necessary and optional） Basic components: Epidural needle, Spinal needle, Anesthesia catheter, LOR indicator syringe, Adaptor, Filter Optional components: 22G/16G subcutaneous needle, 5ml/10ml syringe 4． Function Can achieve intraoperative dosing and analgesia, establish an analgesic dosing channel for postoperative analgesia 5． Factors affecting

1) Patient body position 2) Anesthesiologist experience 6． Advantages of each components, including package a. Epidural needle Needle tip processed by special technics reduces the lesion on nerve and tissue during puncturing; can be made according to clinical request. b. Spinal needle The needle made by special craft can reduce the damage of tissue; three lateral ports design in the needle tube makes it can be used in ozone treatment. c. Atraumatic anesthesia catheter Soft tip prevents damage to vessel, dura mater or spinal nerve being damaged or punctured by hard tip; Springwound catheter tube...

Anesthesia catheter: Made of medical polymer material; Packing: Packed with Tyvek dialysis paper, has better resistance to bacteria and permeability. 8． Scope of application Anesthesia Department, Pain Department, Emergency Department 9． For the best use of this product, or suggestions. 1) Set the patient in a correct body position, especially for osteoarticular diseases patients, or the tube can be stuck in certain parts easily. Check the package, do not use if it has been previously opened or damaged. Wear gloves according to aseptic operation specification and open the package to check whether...

this procedure is occasionally performed when he/she sitting up with his/her back rounded. Locate the appropriate section of the spine once the patient is in position. Clean the area and inject small amount of local anesthetic into the skin at the injection side. 4) Locate the puncture point. Insert the epidural needle into patient’s spinal column slowly and carefully. The stylet shall be drawn out when the needle tip is felt embedded in dense tissue. The scale on the needle can help the operator to judge the depth and location of the insertion of the needle. 5) Connect the prepared syringe with...

membrane surrounding spinal nerves. The membrane is called dura, and the space is epidural space. When the needle tip reaches in epidural space, the LOR indicator syringe balloon will deflate promptly. 7) Then remove the syringe and insert the anesthesia catheter through the epidural needle. After anesthesia, extract the catheter slowly with uniform force to avoid the catheter broken in the body. 10． Contraindication ·Patient refusal ·Coagulopathy ·Spinal canal with tumor, inflammation ·Severe adhesion in epidural space caused by multiple puncture or injection ·Therapeutic anticoagulation ·Skin...
