Silicone Laryngeal Mask Airway
Laryngeal Mask Airway, also known as LMAS, Silicone Laryngeal Mask, Reusable Laryngeal Mask, which is used has two kinds, one is reusable, and is made of medical grade liquid silicone rubber by LSR injection Mold, and the other one is disposable: Intubating LMA with endotracheal tube and LMA with gastric suction channel.
What is Laryngeal Mask Airway Used for?
Silicone Laryngeal Mask is a type of extraglottic airway device aka supraglottic airway device (SAD) which can help oxygenate and ventilate a patient in an emergency or a controlled setting, and which is an effective means of maintaining ventilation and oxygenation in the prehospital,operating theatre,and emergency department environments. Lartngeal Mask Airway is easy to use, which can be successfully inserted alough by inexperienced operators. LMAs avoid the difficulties of attaining and maintaining an adequate face-mask seal, they bypass soft tissue obstruction of the upper airway, and they cause less gastric insufflation than BVM ventilation.
Why choose Liquid Silicone as material for Laryngeal Mask Airway ?
Liquid Silicone Rubber is a high safety material, whicn can achieve 100% food grade and medical grade and meet CE, UPS Class VI, BfR XV, FDA 21 CFR 177.2600, FDA (510K) required certifications (ISO 10993 ) and ect. We can provide medical statement of the material accordingly.
LSR is an inorganic nature, which is clean, plasticizer-free, tasteless, and is water proof, can resist oxidation and some chemical materials like acids and alkali.
For Laryngeal Mask Airway, which need to be put into human's lung directly, need make high safety insurance.Liquid Silicone Rubber can resist to bacteria growth, which will not stain or corrode other materials and also burns to form water vapor and carbon dioxide, not halogens, not toxins etc. Good water and medical contact, it’s suitable for medical area applications.
Silicone Laryngeal Mask Airway's Advantages:
Silicone LAM can obtain, secure, and maintain a patent airway. The laryngeal mask airway is passed beyond the tongue, forming a seal with the laryngeal inlet and eliminating the most common cause of upper airway obstruction in the non-intubated patient. Maintenance of a patent airway with fewer episodes of oxygen de-saturation has been demonstrated for the LAM as compared with the face mask maintenance of the patent airway with fewer episodes of oxygen de-saturation.
Silicone Laryngeal Mask's Disadvantages:
Laryngeal Mask can not isolate the airway so can not protect against the risk of aspiration. Indeed, the LAM has been shown to form a direct conduit between the laryngeal inlet and esophagus by enclosing both. The incidence of regurgitation associated with the use of the LAM varies from 0% to 23%, which is comparable to the incidence of regurgitation associated with general anesthesia administered by other techniques. However, much of the literature concerning regurgitation and aspiration with the LAM is now recognized to be of questionable scientific design.
