[0002] The oxygen humidification device passes oxygen into the sterile water in the humidification bottle through the air inlet pipe, then outputs it through the air outlet pipe and connects it to the patient's oxygen mask.

[0044] Preferably, the driving motor 200 is a reduction motor.

[0045] Driven by the motor, the first gear ring 201h rotates continuously, that is, the stirring blade 300 rotates continuously; the second gear ring 201m deflects intermittently, that is, the intermittent plugging head 403 deflects intermittently.

[0046] The hollow rod 201 comprises two hollow sections, an upper pipe 201a and a lower pipe 201e. The lower end of the upper pipe 201a is movably connected to the upper end surface of the first gear ring 201h.

[0048] Preferably, the rotating tube heads 201f and 201r are in contact but not fixed.

[0049] The rotating shaft 201b passes through the upper end of the upper pipe 201a and is connected to the output end of the driving motor 200. The rotating shaft 201b is placed inside the upper pipe 201a.

[0050] The release head 400 includes an intermittent plugging head 403, the interior of the intermittent plugging head 403 sequentially wraps a bubble plug 404 and a bottom plate 405 from top to bottom, the upper end surface of the bubble plug 404 is in contact with the inner wall of the intermittent plugging head 403, and a movable input head 401 is provided on the bottom plate 405, and the bottom surface of the movable input head 401 is connected to the input pipe 103;

[0051] The lower end of the movable input head 401 is meshed with the lower end of the intermittent plugging head 403 through the transmission gear 402 for transmission.

[0052] Preferably, the number of teeth of the transmission gear 402 is smaller than that of 401 c , and the upper end of the transmission gear 402 is movably connected to the bottom surface of the bottom plate 405 .

[0053] The intermittent plugging head 403 is in an arched semi-enclosed shape, with a plurality of 403a provided at the upper end, 403b provided at the inner side of the lower edge, and 403c fixed at the inner and outer sides above 403b;

[0054] Preferably, 403a is an arc-shaped long strip opening, and multiple 403a are distributed in a ring array on the intermittent sealing head 403. At the same time, the distribution state of 404a on the bubble plug 404 is consistent with the distribution state of 403a. During the intermittent deflection process of the intermittent sealing head 403, 403a will intermittently overlap with 404a, and then oxygen can be released from 404a, and then 404a is closed and the release stops, and this cycle repeats.

[0055] The annular protrusion at the lower end of the intermittent plugging head 403 passes through the bottom surface of the humidifier bottle 100 , the outer side 403c of the protrusion is movably connected to the bottom surface of the humidifier bottle 100 , and the inner side 403c of the protrusion is movably connected to the side 405a of the bottom plate 405 .

[0056] A plurality of 404a are provided on the bubble plug 404, and a columnar 404b is provided in the middle of the bottom surface of the bubble plug 404.

[0057] The movable input head 401 includes 401a, 401a is placed in 404b, and the outer edge of 401a is in contact with the inner edge of 404b;

[0058] 401b is provided on the bottom surface of 401a, 401b penetrates the middle of the bottom plate 405 and is threadedly connected to the middle of the bottom plate 405, 401c is provided at the lower end of 401b, and the thickness of 401c is greater than the thickness of the transmission gear 402; a through hole is provided in the middle of 401c, and an internal thread is provided at the through hole;

[0059] Preferably, the thickness of 401c is greater than the displacement distance of 401a, that is, when 401a follows 401c to move downward, 401c is always in a meshing state with 402.

[0060] 401a, 401b and 401c are connected to 404b;

[0061] Preferably, 401a has a maximum movement range. When 404a closest to the bottom surface of 404 releases bubbles, the medical staff can close the device for manual resetting and add a sufficient amount of sterile water to the inside of 100.

[0062] After the input pipe 103 is threadedly connected to 401c, the upper end is higher than or flush with the upper end surface of 401a.

[0063] Preferably, 401c rotates slowly, and when 401a completes the maximum stroke, the sterile water inside 100 also reaches a state where it needs to be replenished.

[0064] The outer side of the first gear ring 201 h is connected to 302 , and the outer side of 302 is connected to the stirring blade 300 through 301 .

[0065] Preferably, during the intermittent deflection of the intermittent plugging head 403, each time the deflection is performed, from the beginning to the end, 403a and 404a are in a staggered state, and oxygen is released from 403a only once during the deflection process.

[0066] When in use, first inject a sufficient amount of sterile water into the humidifying bottle 100, then connect the input pipe 103 with 401c, and at the same time connect the output port 102 to the patient's respirator, start the drive motor 200, and the stirring blade 300 stirs the sterile water. At the same time, oxygen is input from the input pipe 103 to 404b, and oxygen is released into the sterile water from 404a. The input pipe 103 is a one-way air valve; at the same time, the intermittent plugging head 403 is intermittently deflected, and the oxygen is in an intermittent release state. In the state where oxygen continuously consumes sterile water, the volume of oxygen stored in the humidifying bottle 100 increases. At the same time, with the deflection of the intermittent plugging head 403, 401a gradually moves downward, and more 404a in the bubble plug 404 participate in releasing oxygen. After the 404a closest to the bottom releases oxygen for a period of time, the medical staff can stop inhaling oxygen, replace or reset the device, and replenish sterile water.

[0067] In summary, the hollow rod 201 is used in the device to connect the stirring blade 300 and the release head 400. During the oxygen input process, the sterile water in the humidification bottle is stirred, which helps to humidify the oxygen. At the same time, the intermittently rotating intermittent plugging head 403 makes the release of oxygen intermittent, which helps the formation and rise of bubbles in the water to be more uniform, avoiding the bubbles from rising too quickly and reducing the contact with the water; at the same time, the gas can circulate in the water for many times, gradually reaching a higher humidity saturation, ensuring the humidification of the oxygen;

[0068] During the sterilization process of sterile water, the device will slowly expand the release range of oxygen in the device, that is, the total amount released per unit time, so as to avoid insufficient oxygen concentration in the humidification bottle.
