[0002] Gas inhalation is a common medical method. Its main function is to increase arterial oxygen partial pressure, improve the body's oxygen supply, reduce the respiratory and circulatory burden caused by compensatory hypoxia, and maintain the patient's vital signs.

[0003] Currently, most of the common medical gas inhalation devices on the market are similar in structure. They are mainly composed of a water cup filled with pure water. There is a flow meter on the top cover of the water cup, and a docking tube on the side that connects to the hospital's oxygen pipeline. Oxygen enters the water cup through the docking tube, is moistened with pure water, and then delivered to the patient's nasal cavity through a nasal cannula. There are some functional deficiencies in actual use and there is room for improvement. For example, as the time of supply of water increases, the water in the water cup will continue to decrease. To replenish pure water, the water cup needs to be removed for operation, during which the oxygen supply will be interrupted, which is more troublesome and does not have the function of facilitating water replenishment.

[0004] Now, a novel medical gas supply inhalation device is proposed to solve the above problems. Utility Model Content

[0010] Preferably, a sealing sleeve is sleeved on the rear end of the expansion chamber, and the inner thread of the sealing sleeve matches the outer thread of the rear end of the expansion chamber.

[0011] Preferably, the shape and size of one side of the arc-shaped connecting plate match the shape and size of one side of the pure water cup, and the pure water cup and the arc-shaped connecting plate fit tightly.

[0012] Preferably, a rubber anti-skid pad is glued to one side of the support plate, and the horizontal center lines of the arc-shaped connecting plate, the support rod and the support plate coincide with each other.

[0013] Preferably, an air outlet pipe is installed at the top end of the top cover, and the vertical center lines of the pure water cup and the bottom support coincide with each other.

[0014] Preferably, two groups of pipeline hanging grooves are respectively provided on both sides of the base, and the pipeline hanging grooves are symmetrically distributed about the vertical center line of the base.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the medical gas delivery and inhalation device not only realizes the function of facilitating water replenishment and the function of supporting the wall surface to maintain stability, but also realizes the function of facilitating the winding and hanging of pipelines;

[0016] (1) By providing a water-filling pipe, an expansion chamber, a rubber sealing plug and a sealing sleeve, when in use, the air inlet nut and the oxygen pipe on the wall are quickly connected, the nasal suction tube is connected to the nasal suction tube interface, and the air outlet end is fitted under the patient's nose. The oxygen in the oxygen pipe enters the pure water cup through the air inlet pipe and the air outlet pipe, and after being moistened with pure water, it is sent to the patient's nasal cavity through the nasal suction tube. When the remaining amount of pure water is not much, the medical staff can draw pure water through the syringe, then loosen the sealing sleeve, insert the needle into the expansion chamber, and the needle passes through the rubber sealing plug to reach the inside of the water-filling pipe.
