The application handles anesthesia mask pressure

 

1.2 Materials and Structures

 

    The handle is aluminum core diameter of 0.8 cm, the overall package 0.2cm thick plastic coat stylet produced by the central retaining ring and the left and right wings form: Central fixing ring inside the mouth diameter 2.7cm, embedded in the outer air intakes mask, fixed on the upper edge of the mask, and wearing a fixed gear fixed in the same way; left and right wings downward along the side masks, the mask side of its curvature identical to the level of the lower edge of the mask wall outreach 2.5 cm, the outer edge Alice 2. Ocm, its concave thumb relaxed to allow placement. Handle and mask combination as shown.

 

2 Results

 

    285 cases of 305 patients with handle operation, mask pressure ventilation were successfully completed, no leaks occur; operating doctors agreed that the handle is easy to operate, comfortable hand feeling no fatigue, bladder airtight good, willing to use, I hope the handle contact area with both thumbs to be more comfortable.

 

3 Discussion

 

    Early widespread use of pressurized oxygen mask headband implementation, operation, first prepare headband, and placed under the head of the patient, followed by suspension headband four elastic band, re-adjust the tension of the first four elastic band balance and mask location, need both hands jaw; currently pressurized oxygen mask, mostly hands thumb and thenar pressing the lower edge of the mask wall left and right sides, so that the air bag sealed with patients face. The remaining four fingers hold the lower jaw, the operation is relatively easy to use headband. Therefore, current clinical anesthesia is rarely used headband, headband fixed gear largely abandoned. As the existing mask softer sidewall, pressurized mask wall easily deformed, so that the thumb and thenar pressing mask no fixed focal point, hands, fatigue, bladder and facial tightness is not stable; pressing the top mask can airtight protection mask, but his hands are more fatigue, and difficult for small hands to complete this operation.

 

    Handle solves mask pressurized hand fatigue and leakage problems. As the handle is fixed to the top of the mask, the pressure, the pressure along the top of the mask white mask wall conduction down the mask side wall does not bear the pressure, to maintain the original shape, the balloon force uniform, sealed good. Mask pressure, the hands hold the handle at the bottom of the thumb, the other four fingers jaw, hands and position can be fixed, hard stable, comfortable, easy to operate, easy fatigue.

 

    Since we have 0.2 cm handle made of plastic coat, avoiding contact with the patient appears to be damaged handle the situation; handle the lower edge of the wings, that part of it is operating physician thumb pressurized single-strand lead core composition, surface pressure when the force is too small thumb , partial pressure is too large, comfort is not ideal, here to two or more strands of parallel rows of conductive core

 

Put, would be more desirable.

 

    Handle simple structure, easy to manufacture, factory-scale production can be made of plastic, the handle with the thumb contact area to be improved, the operation will be more comfortable; consider the special role of the headband, the handle can be attached to a fixed central fixed ring gear; handle the number of materials used Although more than headband fixed gear, but each handle a small amount of material, medical costs plus tiny grub.

 

    In short, the handle can be solved when the mask pressure hand fatigue problems, and the operation is convenient, comfortable effort, low cost, is worthy of wider application.
