Introduction of Laryngeal Mask Airway

Scope of application: Kangyuan’s laryngeal mask airway is suitable for artificial ventilation for patients who need general anesthesia and emergency resuscitation, or to establish short-term non-deterministic artificial airways for other patients who need to breathe. Performance: Compared with the blank control solution, the pH difference is ≤1.5; the product is sterile, sterilized by ethylene oxide, and the residual ethylene oxide is not more than 10μg/g.

1. Single-Tube Laryngeal Mask Airway for Single Use

100% medical grade silicone for superior biocompatibility.

Non-epiglottis-bar design provides easy and clear access through the lumen.

5 angular lines appear when the cuff is in flat status,which can avoid the cuff to defom during insertion.

Deep bowl of the cuff provides excellent sealing and prevent the obstruction caused by epiglottis ptosis.

Special treatment of the cuffs surface reduce leak and shift effectively.

Without using laryngoscopy glottis, reduce the incidence of sore throat, glottis edema and other complications.

Can be easily inserted, only need 10 seconds to solve breathing problem.

Non-epiglottis-bar design provides easy and clear access through the lumen.

5 angular lines appear when the cuff is in flat status,which can avoid the cuff to deform during insertion.

Spiral reinforcement minimizes crushing or kinking.

360° bending, strong anti-bending performance, suitable for ventilation during surgery in different positions of patients.

Deep bowl of the cuff provides excellent sealing and prevent the obstruction caused by epiglottis ptosis.

Special treatment of the cuffs surface reduce leak and shift effectively.

Without using laryngoscopy glottis, reduce the incidence of sore throat, glottis edema and other complications.

Guide rod with a shaped arc is selected to facilitate the insertion of the LMA according to the anatomical and physiological structure of the oral and throat of the human.

Can be easily inserted, only need 10 seconds to solve breathing problem.

3. Single-Tube Laryngeal Mask Airway with Epiglottis Bar

Made of 100% imported medical-grade silicone.

Five angular lines appear when the cuff is in flat status,which can avoid the cuff to deform during insertion.Two- -epiglottis-bar design in the bowl, can prevent the obstruction caused by epiglottis ptosis.

Special treatment of the cuff’s surface reduce leak and shift effectively.

Without using laryngoscopy glottis, reduce the incidence of sore throat, glottis edema and other complications.

Can be easily inserted, only need 10 seconds to solve breathing problem.

4. Single-Tube Laryngeal Mask Airway with Epiglottis Bar

Made of 100% imported medical-grade silicone.

Five angular lines appear when the cuff is in flat status,which can avoid the cuff to deform during insertion.Two- -epiglottis-bar design in the bowl, can prevent the obstruction caused by epiglottis ptosis.

Special treatment of the cuff’s surface reduce leak and shift effectively.

Without using laryngoscopy glottis, reduce the incidence of sore throat, glottis edema and other complications.

Can be easily inserted, only need 10 seconds to solve breathing problem.

5. Double-tube Reinforced Laryngeal Mask Airway

100% medical grade silicone for superior biocompatibility.

Non-epiglottis-bar design provides easy and clear access through the lumen.

There are two separate ventilation and drainage pipelines, which are matched and connected with the human airway and esophagus, which significantly reduces the occurrence of reflux and aspiration, and at the same time facilitates the placement and positioning of the laryngeal mask.

The independent gastric drainage tube can manually and negatively suction the stomach contents to avoid the danger of reflux.

Improved and enlarged inflatable cuff, strengthens the sealing of the throat, can carry out positive pressure ventilation for a long time, and expand the use range of LMA.

Without using laryngoscopy glottis, reduce the incidence of sore throat, glottis edema and other complications.

Guide rod with a shaped arc is selected to facilitate the insertion of the LMA according to the anatomical and physiological structure of the oral and throat of the human.

Can be easily inserted, only need 10 seconds to solve breathing problem.

The integrated cover pad can be used as a tooth pad, easy to fix, only need a tape to solve the problem of fixing.

Clinical Application

Direction for Use:

1. The LMA, should check with the specifications of product labeling.

2. To exhaust the gas in the airway of the laryngeal mask airway so that the hood is completely flat.

3. Apply a small amount of normal saline or water soluble gel for lubrication in the back of the throat cover.

4. The patient’s head was slightly back, with his left thumb into the patient’s mouth and traction of the patient’s jaw, in order to widen the gap between the mouths.

5. Using the right hand to hold the pen holding the laryngeal mask, to make available, the index finger and middle finger against the cover connection body and the ventilation tube laryngeal mask, cover the mouth towards the direction along the midline of lower jaw, tongue sticking down pharyngeal LMA, until no longer advance so far. Also can use reverse the method of inserting laryngeal mask, just cover the mouth toward the palate, will be placed in the mouth to the throat at the bottom of the laryngeal mask, and 180°after rotation, and then continue to push down the laryngeal mask, until can’t push so far. When using the enhanced or ProSeal laryngeal mask with guide rod. The guide rod can be inserted into the air cavity to reach the designated position, and the insertion of the laryngeal mask can be drawn out after the insertion of the laryngeal mask.

6. In the move before the other hand gently with finger pressing to prevent laryngeal mask airway catheter displacement.

7. According to the nominal charge to cover bag filled with gas (air amount can’t exceed the maximum filling mark), connect the breathing circuit and assess whether good ventilation, such as ventilation or obstruction, should according to the steps of re insertion of laryngeal mask.

8. To confirm the position of the laryngeal mask is correct, cover the tooth pad, fixed position, maintain ventilation.

Contraindication:

1. Patients who were more likely to have a full stomach or stomach content, or who had a habit of vomiting and other patients who were prone to reflux.

2. Patients with laryngeal edema, acute inflammation of the respiratory tract, and pharynx abscess.

3. Throat disease causes airway obstruction, reduced lung compliance, or high airway resistance, people who require positive pressure ventilation.

4. Patients whose trachea is compressed and softened and have airway obstruction after anesthesia.

5. Those who are allergic to product materials.

6. Patients considered by clinicians to be inappropriate for this product.

Clinical practice of double-tube laryngeal mask:

Storage and Transportation:

The means of transportation should be clean and hygienic, and the source of fire should be isolated. Products should be stored in relative humidity of not more than 80%, the temperature is not more than 40 degrees Celsius, no corrosive gases and good ventilation clean room.
