4. the laryngopharyngeal lesion causes obstruction of the respiratory tract, reduced lung compliance, or high airway resistance.

5. patients with laryngeal edema, acute respiratory inflammation and throat abscess should be used with caution.

1. this product is a disposable product, which is damaged in packaging and is strictly prohibited to be used and destroyed after use.

2. this product is sterilized by ethylene oxide and is sterile for two years.

3. the production batch number and the expiry date can be seen in the packing seal, and the sterilization date is shown in the packing box.

4. during the use of the laryngeal mask, attention should be paid to the airway or pulmonary reflux aspiration.

5. if the position of the patient's head or neck is changed with the beginning of the insertion of the laryngeal mask, it is necessary to confirm whether the laryngeal mask is unblocked and unblocked.

6. if there are laser and electric burning devices, it is necessary to prevent the throat cover from being flammable.

7. detect air leakage before use, if there is air leakage, no use;

8. read the product manual before use;

[use] : 1, l. 0 is suitable for the newborn < 5 kg, l. 5 use is suitable for the weight 5 kg - lokg baby, 2.0 is suitable for the pediatric weight lokg - 20 kg, 20 kg - 2.5 is suitable for the weight 30 kg of pediatric, 30 kg - 3.0 is suitable for the weight 50 kg, 4.0 is suitable for the average adult weight 50 kg to 70 kg, 70 kg - 5.0 is suitable for the weight lookg overweight adults;

2. first check whether there is any damage to the packaging, if any damage is prohibited;

3. open the package from the tear opening, remove the inflatable throat mask, and fill in the right amount of gas to detect whether the gas is leaking; inflatable laryngeal mask to check for obvious defects or sharp edges.

smoke gas inside the net bag before 4, insert, insert time available blind insertion method guided by or in the laryngoscope, insert after balloon inflated to clinical or standard requirement, and then connect to form a complete set of equipment used;

5. the operator shall be a professional with rich clinical experience;

6. the throat mask should be kept for less than 12 hours, and the respiratory secretions should be cleared in time.

7. for patients who have been left for more than 12 hours, they should closely monitor the movement of the pipe after the catheter is successful, so as to avoid bending and folding of the pipe and keep the pipeline open; at the same time, prevention of pipe slip, after the catheter should be used in a timely manner with the medical strap to be fixed, and each interval to exchange the fixed ear to prevent the injury. wash with warm water before and after the nutrition, and use the interval to wash the water to prevent the blockage of the pipe. when the patient is turned over and cleaned, the tube should be placed first to prevent the tube from being removed. when the patient is engaged in sputum aspiration, the movement should be gentle and rapid, prevent touching the indwelling pipe, cause shift. keep the patient's oral cavity clean, and make a daily allowance for the cleaning and cleaning of the secretions.

8. the air leakage pressure of the single-cavity laryngeal mask is 20cmh2o, and the leakage pressure of the double-cavity laryngeal mask is 30cmh2o on average.

[use method] throat mask insertion.

1. select the appropriate model and fill in the right amount of gas to detect whether the gas is leaking; inflatable laryngeal mask to check for obvious defects or sharp edges.

2. exhaust gas in the inflatable throat hood with a syringe that conforms to gb/t1962.1 and 6% (ruhr) external conical connector. (figure 1)

3. apply a small amount of water-soluble lubricant to the back of the throat, and hold the mask in one hand. (figure 2)

4. open the patient's mouth and place the back of the throat cover on the back of the front teeth. (figure 3)

5, use forefinger assisted laryngeal mask along the hard palate and the soft palate backward order into, continuous along the direction of the head back to swallow cavity pressure parts until characteristic feel resistance (hint to esophageal sphincter). (figure 4)

6. gently press the tube body with the other hand before removing the index finger to prevent the throat shift. (figure 5)

7, with 6% meet the requirements of gb/t1962.1 syringe (ruhr) cone joint top valve inflatable to indicate the airbag (at best cannot exceed the maximum your), placing dental pad, a fixed position, keep ventilation. (figure 6)

laryngeal mask out

after the use is finished, the application is in accordance with the 6% (ruhr) external taper connector of the external conical connector. inflatable laryngeal mask can be pulled out directly.
