The face shield leading edge should be narrow as far as possible, and as far as possible away from patient's eyes, compressing patient eyeball because of when using face shield, must closely be fixed in patient's face with face shield when avoiding using, and is very big to patient's face pressure.Roomy as the face shield leading edge, then certainly will oppress patient's eyeball.A part of patient eyes under narcotism are opened, and then may cause patient's ophthalmic injuries, ischemia or infection, and no matter open severe patient close by patient's eyes, all may inspire oculocardiac reflex, even cardiac arrest, so the face shield leading edge should be narrow as far as possible.

Mask body 3 adopts hard material, can bear pressure.Annular closed air bag 4 adopts soft materials, can be fully to kiss and be close to the patient is facial.

Bite-block 6 is directly fixed on the latter half of center of face shield, adopts rigid plastics to make, can resist patient's gmatjpdumamics.Attract hole 10 to be fixed in the one side, with its unification body, bite-block 6 and attract hole 10 to answer driving fit to fix with face shield is latter half of, air tight when guaranteeing to use.

The gastric content that attracts hole 10 to be used for sucking-off patient mouth sputum, saliva or to backflow prevents the mistake suction.To be the old asthenia patient of gastroscopy person more because of need, and the gerontal patient merges respiratory system disease more, and cough, expectoration symptom are arranged more, and the patient inserts bite-block and gastroscope and stimulation patient and quickens to salivate when anesthesia is more shallow in mouthful sometimes.Moreover a part of patient merges potential gastric retention, in the inlet that then may backflow in the inspection.Above factor all may influence patient respiratory and even suffocate, and attracts hole 10 to stretch in patient's mouth so set up one, is beneficial to foreign bodies such as sucking-off patient sputum, saliva and gastric appearance, prevents to inhale, suffocate by mistake.

Encircle cover capsule 9 and be arranged in the bite-block 6 the tubular film structure thin for the centre, that two ends are wide.Its upper end driving fit is bonded in two-port on the bite-block 6, and its lower end driving fit is bonded in the bite-block inwall, and stickup face should be firm, and is intrinsic pressure resisting higher blister cavities.Encircle between cover cyst membrane and the bite-block perisporium and form an annular closed blister cavities, in fill air, air pressure can reach more than the 25hPa, makes it can tightly embrace gastroscope optical fiber, prevents to leak gas or small leak is only arranged.The tubulose duct that encircles cover capsule intermediate formation is that gastroscope is inserted hole 9, is gastroscope optical fiber Vomitory, and its natural internal diameter should be suitable with gastroscope optical fiber external diameter, so that its surface fully contacts with optical fiber surface.Encircle the cover cyst membrane and made by the certain elastic flexible material of tool, make its internal diameter that certain transmutability be arranged, can become with gastroscope optical fiber external diameter, because of gastroscope optical fiber external diameter inconsequent, its front portion is often greater than its rear portion.Encircling cover cyst membrane surface should be fully smooth, and it is minimum that its skin-friction force is reduced to, and the unlikely relative slip that influences two contact surfaces is beneficial to inserting and transfering to of gastroscope optical fiber.Can smear the medical lubricant of one deck encircling cover cyst membrane surface in case of necessity.As vaseline, povidone iodine, liquid paraffin, lubricated amyl colloid etc.
