[0002] In the existing technical methods, when providing mask oxygen inhalation for rescuing patients, the current EC technique is used, and the airway of the patient is opened by hand force with the technique, or during general anesthesia surgery, the anesthesiologist also uses the EC technique for oxygen inhalation or lifts the lower jaw for effective oxygen inhalation and intubation. The disadvantages are that the operator is not labor-saving and not convenient. When encountering an operator with small hands or an obese patient, the operation will be affected, delaying the effective rescue time, and the trachea cannot be fully exposed, hindering effective tracheal intubation and effective oxygen input.

[0021] In the description of the present utility model, it should be noted that unless otherwise specified, the meaning of "a plurality of" is two or more; the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation on the present utility model. In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0022] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0023] Referring to Figure 1 , a portable EC jaw lifter provided by the present utility model includes a facial pressing ring and a lower jaw fixing mechanism. The facial pressing ring is used to press the oxygen inhalation mask, and the lower jaw fixing mechanism is used to lift the patient's lower jaw. The facial pressing ring includes a U-shaped pressing ring 1 and a grip rod 2. The grip rod 2 is connected to the outer side of the U-shaped pressing ring 1. The lower jaw fixing mechanism includes a pull rod 3 and an arc-shaped support 4. The pull rod 3 is connected to the arc-shaped support 4. A circular hole is vertically opened on the grip rod 2, and the pull rod 3 vertically passes through the circular hole on the grip rod 2 and is movably connected thereto. The pull rod 3 can be lifted up and down with the circular hole on the grip rod 2 as the support point, and can also use the circular hole on the grip rod 2 as the fulcrum of the lever. Hold the grip rod 2 and the pull rod 3 tightly with one hand, so that the U-shaped pressing ring 1 and the arc-shaped support 4 at the other end are forced to closely adhere to the patient's face and lower jaw.

[0024] The grip rod 2 and the pull rod 3 are arc-shaped structures and have the same arc direction. After the jaw lifter is placed in place, it is convenient to hold the grip rod 2 and the pull rod 3 tightly with one hand, leaving the operating space for the other hand to perform positive pressure ventilation by squeezing the balloon or using a ventilator. In actual work, since most medical staff are female and have relatively small palms, when encountering a relatively obese patient, the patient has more facial fat, and female fingers are relatively short. It is very inconvenient to use the EC technique to open the patient's airway. By using the jaw lifter, it can help medical staff smoothly open the patient's airway for effective tracheal intubation or oxygen delivery.

[0025] In order to better implement the present utility model, further optimization is made to the above structure. A soft cushion ring 5 is provided at the bottom of the U-shaped pressing ring 1. The soft cushion ring 5 is an airbag cushion to prevent facial injuries to the patient during pressing.

[0026] In order to better implement the present utility model, further optimization is made to the above structure. The arc-shaped support member 4 is a curved structure that fits the curve of the lower jaw. When the arc-shaped support member 4 lifts the lower jaw, the force is evenly distributed to prevent it from falling off during lifting. A soft cushion 6 is provided at the end of the arc-shaped support member 4. The soft cushion 6 is an elastic rubber pad to prevent scratching the skin of the patient's lower jaw.

[0027] In order to better implement the present utility model, further optimization is made to the above structure. Three arc-shaped support members 4 are provided. The three arc-shaped support members 4 are in an E-shaped structure to evenly disperse the weight received during lifting to each arc-shaped support member 4. A fixed clip 201 is provided on the grip rod 2, and a fixed card slot 301 is provided on the pull rod 3. The fixed clip 201 and the fixed card slot 301 are clamped to save effort.

[0028] Working principle:

[0029] During use, first put the oxygen inhalation mask on the patient's face, then press the U-shaped pressing ring 1 against the edge of the oxygen inhalation mask to fix it. Then, the arc-shaped support member 4 is pressed against the patient's lower jaw to make the arc-shaped support member 4 fit tightly with the patient's lower jaw. Next, hold the grip rod 2 tightly with one hand to ensure that the oxygen inhalation mask is close to the patient's face, and pull the pull rod 3 with the other hand to naturally lift the patient's lower jaw to open the patient's airway. Then, hold the grip rod 2 and the pull rod 3 with one hand, and rely on the lever principle to make the U-shaped pressing ring 1 and the arc-shaped support member 4 close to the patient's face and lower jaw to ensure effective oxygen delivery to the patient.

[0030] In addition, this device can also assist in tracheal intubation. First, press the U-shaped pressing ring 1 against the face at the edge of the patient's mouth and nose to fix it. Then, the arc-shaped support member 4 is pressed against the patient's lower jaw to make the arc-shaped support member 4 fit tightly with the patient's lower jaw. Next, hold the grip rod 2 with one hand and pull the pull rod 3 with the other hand to naturally lift the patient's lower jaw to open the patient's airway, which can make tracheal intubation more effective.

[0031] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
