Abstract
The utility model relates to an air leak-proof mask, which is formed by a mask body. An air inlet pipe is arranged on one side of the mask body. An air bag is arranged at an opening on the other side. A high-density sponge filling block is arranged between the two ends of the air bag. A through hole is arranged in the high-density sponge filling block. A crack is arranged in the side wall of the through hole and is extended to one side surface of the high-density sponge filling block. A plunger is arranged in the through hole. A bonding layer is arranged on the high-density sponge filling block on the two sides of the crack. A gastric tube is placed through the through hole in the high-density sponge filling block to solve the technical problem that air is leaked because the mask and the face cannot be attached tightly under the existence of the gastric tube, so air leakage caused by the gastric tube is thoroughly avoided. The air leak-proof mask is suitable for general-anesthesia surgical patient into whom the gastric tube is placed and the patient who bears the detaining gastric tube and undergoes the noninvasive mask ventilation treatment. Since the high-density sponge is elastic, the gap and the through hole do not leak air, so the air leak-proof mask is also suitable for the general-anesthesia patient bearing no gastric tube.
Description
Technical field:
This utility model relates to the mankind life article, relates in particular to medical apparatus and instruments, and particularly face shield is a kind of anti-gas-leak face shield specifically.
Background technology:
In the clinical medicine, surgical operation especially operation on digestive tract need be placed stomach tube before art.But when the patient is implemented general anesthesia,, influence the face shield ventilatory effect because the existence of stomach tube when the general anesthesia induction face shield is ventilated, because of face shield can't fit tightly with face, can cause inward mask leakage.Leak gas when serious, can cause hypoventilation and produce life danger.In the prior art, the one, on the transparent plastic face shield, make a call to a side opening, the aperture is a bit larger tham the stomach tube external diameter.In the hole, put into the medium size cuff for endotracheal catheter, with all-purpose adhesive and masking aperture gummed, the outer part of the nose of stomach tube pass-out from the cover capsule.Blow a cover capsule (about 3ml gas) with the 5ml syringe during operation, make face shield stomach tube exit air tight.Emit gas in the cover capsule after the intubate, stomach tube is extracted out from the face shield side opening.Other method is to open a groove at face shield air inlet pipe place, during anesthesia stomach tube is passed and be stuck in groove from air inlet pipe, after the intubate stomach tube is taken out from face shield air inlet pipe groove.More than two kinds of methods, when the patient anaesthetizes, need successively twice stomach tube and vacuum extractor to be disconnected, stomach tube is put into taking-up again, complex operation earlier from face shield side opening or air inlet pipe groove.And, because of each operation all needs stomach tube and vacuum extractor are disconnected, therefore can't guarantee that stomach tube is in the vacuum suction state all the time, the patient who needs is continued gastrointestinal decompression causes harmful effect, and having increased the patient does not simultaneously have duration of ventilation yet, has risk.
Summary of the invention:
The purpose of this utility model is to provide a kind of anti-gas-leak face shield, and described this anti-gas-leak face shield will solve the technical problem that face shield leaks gas easily in the prior art.
This anti-gas-leak face shield of the present utility model is made of a mask body, one side of described mask body is provided with an air inlet pipe, opening part along the mask body opposite side is provided with an air bag, wherein, be provided with a high-density sponge filling block between the two ends of described air bag, be provided with a through hole in the described high-density sponge filling block, be provided with a crack in the sidewall of described through hole, described fracture extension is to a side of high-density sponge filling block.
Further, be provided with a plunger in the described through hole.
Further, the high-density sponge filling block of both sides, described crack is provided with tack coat.
Further, be provided with an air-filled pore in the described air bag.
Operation principle of the present utility model is: after the general anesthesia induction patient is sleeping, the face shield after the inflation placed patient's actinal surface portion, takes out plunger, the crack of stomach tube in the high-density sponge filling block snapped in through hole, and again with crack closure, the ventilation of row face shield.The face shield ventilation finishes the back and takes out stomach tube by the crack from through hole, removes face shield, the circulation of qi promoting cannula.If the patient does not have stomach tube, also can use this face shield to ventilate, its using method is identical with conventional face shield.The tack coat of both sides, crack can make the high-density sponge filling block fit tightly before and after placing stomach tube.
This utility model and prior art contrast, and its effect is actively with tangible.This utility model is provided with a breach in ring-shaped gasbag, the high-density sponge filling block is set in breach, place stomach tube by through hole in the high-density sponge filling block, thereby thereby avoided causing face shield can't fit tightly the technical problem that causes inward mask leakage, the gas leakage that can thoroughly avoid stomach tube to cause with facial owing to the existence of stomach tube.This utility model is applicable to the general anesthesia operation patient who places stomach tube, also is applicable to the patient of the noinvasive face shield ventilation therapy of indwelling gastric tube.Because the high-density sponge high resilience, its gap and through hole can not leak gas; And sponge combines closely with the air bag part, so this face shield is equally applicable to not have the patient with general anesthesia of stomach tube.

The specific embodiment:
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, anti-gas-leak face shield of the present utility model, constitute by mask body 1, one side of described mask body 1 is provided with an air inlet pipe 2, an other side of described mask body 1 is provided with a packing ring 3, be provided with an air bag 4 along described packing ring 3, be provided with a high-density sponge filling block 5 between the two ends of air bag 4, be provided with a through hole 6 in the described high-density sponge filling block 5, be provided with a crack 7 in the sidewall of described through hole 6, described crack 7 extends to a side of high-density sponge filling block 5.
Further, be provided with a plunger 8 in the described through hole 6.
Further, the high-density sponge filling block 5 of 7 both sides, described crack is provided with tack coat.
Further, be provided with an air-filled pore 9 in the described air bag 4.
