Description

Aid for facial mask {A SUPPLEMENTARY APPARATUS TO FACE MASK}

TECHNICAL FIELD The present invention relates to a device for use in performing positive pressure ventilation due to loss or reduction of breathing of a patient, and more particularly, to a structure of a breathing device that enables a sealed contact between a patient and a breathing device. .

If the patient loses spontaneous breathing due to general anesthesia or for some reason and breathes the patient with positive pressure, a sealed contact is usually required between the patient and the breathing apparatus. The most commonly used methods are endotracheal intubation and facial mask. In the case of endotracheal intubation, the tube is placed into the airway and the attached balloon is inflated to be in close contact with the trachea. Facial masks are used in close contact with the face at the appropriate pressure.

There are many types of face masks, but the transparent disposable mask shown in FIG. 1 is the most widely used. The face mask is a part that connects to a respirator (not shown), a body made of transparent plastic, and a cushion part that is in close contact with the face part and inflate with air. The ohio anatomic mask shown in FIG. 2 is also used for the same purpose.

Although there are various methods of using a face mask, a general method of using a conventional face mask is illustrated in FIGS. 2 and 3. Referring to FIG. 3, the thumb and the index finger are in close contact with the mask on the face, and the remaining fingers pull the mandible to maintain the airway and pull the jaw toward the mask. The arrow 31 of FIG. 3 illustrates the application of pressure to both sides of the face mask with one hand, and the pressure is applied to the face so that the mask is in close contact with the face part to provide positive pressure ventilation.

At this time, if the patient's face is larger than the operator's hand using the mask, the operator's thumb and index finger cannot cover the entire mask. Therefore, as shown in Fig. 4, the pressure toward the face is applied to only one side of the mask (arrow 43), and the gas that breathes into this place is leaked (arrow 41) by not allowing the opposite side of the mask to come into close contact with the face part (arrow 41). There will be no.

In this case, both hands are used to pressurize the mask. In this case, both hands of the operator are used for the mask pressure. Therefore, in order to make positive pressure breathing with a reservoir bag or an ambu bag, I need one more person.

It is therefore an object of the present invention to provide an apparatus for allowing a face mask for breathing of a patient to be closely adhered to the face of the patient.
