1, the negative plate should be chosen to be rich in blood vessels closest to the surgical site of the muscle (recommended in the arteries of the upper arm and thigh).
2. It is best to scrape off the hair first and then use alcohol to remove the oil dander on the skin, etc., and then paste the negative plate on the circuit after wiping it dry, so as to reduce the impedance value and achieve a safer effect.
3, when determining the patient's surgical site in the case of not hindering the operation, choose the closest position to the surgical site to paste, avoid finger contact with the conductive adhesive surface and pull apart carefully and flat against the four corners of the pressure.
4. Using the circuit board with wires: Insert the circuit board connector correctly into the electrosurgical circuit socket holder. When using the circuit board without wires, you need to check whether the circuit line is good, open the chuck and put the circuit patch to the conductive adhesive surface and really clamp it and then pull it gently to make sure that it will not be loosened, and then insert the connector into the circuit socket.
5. Paste the circuit board as vertically as possible along the longitudinal position of the blood vessel distribution, which is conducive to the recovery of current.
High-frequency electrocautery negative plate use (two)
6, if the loop plate paste position is the upper arm or thigh, should avoid not to happen to their own touch or overlap of the loop plate.
7. Before the skin electrodes are ready to be placed, the electrodes and wires should be inspected for damage or expiration to avoid accidents.
8. The negative electrode plate should not be attached to the protruding part of the bone, the physiological curvature, the dry place of the skin, the joints and the artificial implanted metal parts or the position near the ECG electrode line in order to avoid burns caused by the poor current circuit.
9, the negative plate can not be attached to the waist, armpits and parts of the body under pressure, which is not conducive to the dissipation of heat, will lead to thermal burns due to the concentration of heat.
10, the corners of the negative plate must not be rolled up, the pole plate and the human body to reduce the contact area will increase the impedance of the current recycling, which will lead to frequent alarms due to impedance caused by the electric knife is too large, the head of the knife no output or the possibility of burns.
11, the negative pole plate paste position can not and surgical position into a straight line through the chest cavity, especially patients with heart disease and patients with stents.
