Examples

The invention is further described below with reference to the accompanying figures 1-4:

the utility model provides an oxygen inhalation mask 10 for emergency department, please refer to fig. 1 and 2, the oxygen inhalation mask 10 for emergency department includes oxygen inhalation mask body 100, air inlet assembly 200, expiration assembly 300 and suction tube 400.

The air inlet assembly 200 includes a first air inlet pipe 210 disposed inside the oxygen mask body 100, an oxygen collecting member 220, and a second air inlet pipe 230 disposed outside the oxygen mask body 100. Wherein the second intake pipe 230 is connected to and communicates with the first intake pipe 210.

In the present embodiment, the oxygen collector 220 has an oxygen collecting region (not shown). The nose 500 and nostrils 600 are adjacent to the oxygen collection area. In the present embodiment, the oxygen collecting member 220 is opened with an air inlet (not shown). The air inlet is communicated with the oxygen collecting area. In the present embodiment, the first intake pipe 210 includes a first straight section 211, a bent section 212, and a second straight section 213, which are connected in sequence. One end of the first straight section 211, which is far away from the bent section 212, is connected and communicated with the second air inlet pipe 230, and one end of the second straight section 213, which is far away from the bent section 212, is connected and communicated with a hole wall (not shown) of the air inlet hole.

Further, in the present embodiment, please refer to fig. 1 and 3, the first intake pipe 210 is provided with a first valve flap 240. The first flap 240 has a first end 241 hingedly connected to an inner wall (not labeled) of the second straight section 213 and a second end 242 that may be positioned closer to or farther from the nose 500 and nares 600 upon impingement by the airflow. Wherein the first end 241 is disposed close to the oxygen mask body 100, and the second end 242 is disposed away from the oxygen mask body 100.

According to the above arrangement of the air intake assembly 200, when a patient inhales, the gas in the oxygen collection region is inhaled, and in the continuous inhalation process, the oxygen collection region is at a negative pressure, because the first air inlet pipe 210 contains oxygen conveyed by the second air inlet pipe 230, the first valve flap 240 is opened under the negative pressure, the oxygen enters the oxygen collection region for the patient to inhale, and when the inhalation is finished and the exhalation is started, the first valve flap 240 is closed to prevent carbon dioxide from entering the first air inlet pipe 210. It should be noted that, in the present application, the curved section 212 is designed to buffer oxygen entering the first air inlet pipe 210 from the second air inlet pipe 230, and when exhaling, the impact force of the exhaled air on the first flap 240 can be made larger than the impact force of oxygen entering the second straight section 213 from the curved section 212.

In the present embodiment, referring to fig. 1 and 2, the exhalation module 300 includes a plurality of exhalation tubes 310. The oxygen collecting member 220 is provided with a plurality of first air outlets (not shown), and the oxygen mask body 100 is provided with a plurality of second air outlets 110. The opposite ends of the exhalation tube 310 are connected to and communicate with the first and second exit apertures 110 in a one-to-one correspondence. Referring to fig. 1 and 4, the exhalation tube 310 is provided with a second valve flap 320. The second flap 320 has a third end 321 hingedly connected to the inner wall of the exhalation tube 310 and a fourth end 322 that may be closer to or farther from the nose 500 and nares 600 upon impact of the airflow. Wherein the third end 321 is disposed near the oxygen collector 220 and the fourth end 322 is disposed far from the oxygen collector 220.

According to the arrangement of the air outlet assembly, when the patient exhales, the first flap 240 is closed, the exhaled air is exhausted from the exhalation tube 310, and the second flap 320 is opened by the air flow to make the exhaust smooth.

It should be noted that, in this embodiment, the aperture of the first outlet hole is smaller than the aperture of the inlet hole to ensure that the oxygen supply of the patient is sufficient. It should be noted that, in this embodiment, a plurality of first air outlet holes are equidistantly spaced around the air inlet hole. So that the air outlet is more uniform.

In this embodiment, one end of the suction tube 400 is located outside the oxygen mask body 100, and the other end of the suction tube penetrates through the oxygen mask body 100 and is located near the mouth 700, so that the patient can drink water conveniently. In addition, in the present embodiment, the edge of the oxygen mask body 100 is provided with a pressure-proof sponge 800 to prevent the oxygen mask body 100 from pressing the face.

In this embodiment, it should be noted that the oxygen inhalation mask body 100 may further be provided with a mist injection port (not shown), so that a small amount of moisture can enter the oxygen inhalation mask body 100, and the respiratory mucosa of the patient is prevented from being damaged under the dry condition. The setting position of the mist spraying port is not particularly limited, and all the functions can be realized.
