DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, purposes and effects achieved by the application easy to understand, the application is further described below in combination with specific embodiments.

[0035] Embodiment one, the application discloses a humidification oxygen therapy device for respiratory medicine, referring to Figure 1 and Figure 2 , comprising a bottle body 1, an air inlet cover plate 2 is arranged at the upper end of the bottle body 1, air inlet pipes 21 and air outlet pipes 22 are respectively fixedly connected to the left and right sides of the outer surface of the air inlet cover plate 2, a humidification structure 4 is arranged on the inner surface bottom wall of the bottle body 1 and is in communication with the air inlet cover plate 2, a humidification auxiliary structure 5 is arranged at the upper end of the humidification structure 4 and is located in the inner cavity of the bottle body 1, a heater 3 is fixedly connected to the upper end of the air inlet cover plate 2, and an electric heating wire 31 is wound in the inner cavity of the air inlet cover plate 2 and is connected to the heater 3 through a wire.

[0036] During the operation of the embodiment, the oxygen valve opening of the ward is connected to the air inlet pipe 21, and the oxygen is evenly distributed into the humidification structure 4 through the action of the air inlet cover plate 2, and is sent into the clean water in the bottle body 1 through the cooperation of the humidification structure 4 and the humidification auxiliary structure 5. The fine bubbles formed by the humidification structure 4 enter the water body, and the humidification auxiliary structure 5 is driven by the driving action of the humidification structure 4 to further disperse the bubbles. At the same time, the oxygen humidity is increased by the active atomization of the humidification structure 4, the humidification degree of the oxygen is improved, and the oxygen therapy effect is improved.

[0037] Further, when used in winter, although the storage temperature does not change, the transportation pipeline does not have related heating equipment, and the oxygen transported to the ward has a low temperature. The low-temperature air will cause chronic damage to the respiratory tract after being inhaled by the patient. The heater 3 can reduce the damage to the patient by heating the oxygen with the electric heating wire 31.

[0038] In Embodiment Two, based on Embodiment One, the air inlet pipe 21 cooperates with the air distribution chamber 26 and the communication hole 25 to make the oxygen evenly distributed in the air distribution chamber 26 and then enter the humidification structure 4, realizing uniform humidification of the oxygen. The conical mist catching net 28 in the center pipe 24 can capture the excess liquid water in the oxygen and make it return, avoiding excessive humidity. The clamping groove 27 cooperates with the spring lock tongue 11 and the spring sliding block 23 to realize the tight locking and sealing of the air inlet cover plate 2 and the bottle body 1, and facilitate disassembly for water filling, replacement or cleaning. The electric heating wire 31 is inside the air distribution chamber 26, which can assist in adjusting the humidification conditions.

[0039] Further, referring to Figure 2 The center pipe 24 is fixedly connected to the inner surface top wall of the air inlet cover plate 2, the inside of the center pipe 24 is hollow, and the upper side of the center pipe 24 is in communication with the air outlet pipe 22. The inner cavity of the air inlet cover plate 2 and the inner cavity of the center pipe 24 are jointly provided with the air distribution chamber 26 which is in communication with the air inlet pipe 21. A plurality of communication holes 25 which are in communication with the humidification structure 4 are annularly distributed on the inner wall of the air distribution chamber 26. The spring sliding block 23 is slidingly connected to the lower end of the air inlet cover plate 2 through the annular groove. The conical mist catching net 28 is fixedly connected to the lower part of the inner surface of the center pipe 24. The electric heating wire 31 is inside the air distribution chamber 26.

[0040] The oxygen enters the air distribution chamber 26 through the air inlet pipe 21, and is evenly distributed in the air distribution chamber 26 and then enters the air distribution pipe 41 through each communication hole 25. The oxygen which has completed humidification needs to pass through the conical mist catching net 28 first. The conical mist catching net 28 is a conventional coarse filter equipment which can capture the excess liquid water in the oxygen and make it return to the humidification water along the conical surface, avoiding excessive humidity. The capture precision is arranged according to the actual humidification demand.

[0041] Further, referring to Figure 3The outer surface of the center tube 24 is symmetrically provided with a clamping groove 27, and the inner surface of the bottle body 1 is symmetrically provided with a spring locking tongue 11 matched with the clamping groove 27. The spring sliding block 1 is in close contact with the upper end of the bottle body 1, and the bottle opening of the bottle body 1 is separated from the inner cavity top wall of the air inlet cover plate 2.

[0042] The clamping groove 27 is clamped by the spring locking tongue 11, and the spring sliding block 1 is matched with the upper end of the bottle body 1, so that the air inlet cover plate 2 and the bottle body 1 are tightly locked together to realize the sealing of the bottle body 1.

[0043] Further, when water needs to be added or disassembled for cleaning, the air inlet cover plate 2 is pressed downward to make the clamping groove 27 pass the spring locking tongue 11, then the air inlet cover plate 2 is rotated to drive the clamping groove 27 to be misaligned with the spring locking tongue 11, and the air inlet cover plate 2 is pulled out from the bottle body 1, so that the water can be added, replaced or cleaned conveniently.

[0044] In example three, based on example two, the cooperation of the gas delivery pipe 41, the distribution assembly 44 and the nano filter element 42 makes part of the oxygen pass through the nano filter element 42 to form fine bubbles, increases the contact area with water to promote humidification; the cooperation of the branch pipe 442 of the distribution assembly 44 and the driving assembly 43 utilizes oxygen to drive the humidification auxiliary structure 5 to rotate, breaks the bubbles to improve the exchange rate of oxygen and water; the cooperation of the distribution pipe 441, the branch pipe 443 and the uniform gas pipe 444 realizes uniform distribution of oxygen to ensure the stability of humidification effect.

[0045] Further, referring to Figure 5 The humidification structure 4 includes the annularly distributed gas delivery pipe 41 arranged in the inner cavity of the bottle body 1, the upper side of each gas delivery pipe 41 is communicated with the uniform gas cavity 26 through the adjacent communication hole 25, the inner surface bottom wall of the bottle body 1 is provided with the driving assembly 43, the outer surface of the driving assembly 43 is provided with the nano filter element 42 fixedly connected with the inner wall of the bottle body 1, the lower part of the inner cavity of the bottle body 1 is arranged with the active atomization assembly 45 communicated with the adjacent gas delivery pipe 41, and the tail end of the gas delivery pipe 41 is provided with the distribution assembly 44 communicated with the driving assembly 43.

[0046] The oxygen is delivered to the distribution assembly 44 through the gas delivery pipe 41, and part of the oxygen passes through the nano filter element 42 into the water through the distribution of the distribution assembly 44, and fine bubbles are formed in the water, the contact area of oxygen and water is increased to promote the spread of water molecules to oxygen, thereby realizing the humidification effect of oxygen;

[0047] Further, another part of the oxygen enters the driving assembly 43 through the distribution assembly 44, and then drives the humidification auxiliary structure 5 to rotate through the driving assembly 43, realizes the breaking of the bubbles, and further promotes the exchange rate of oxygen and water.

[0048] It should be particularly pointed out that the above-mentioned nano filter core 42 is a kind of microporous filter core, which is commonly used in air purifiers or dust collectors, and its structure can make gas molecules pass freely, but large molecules such as water molecules cannot pass through the nano filter core 42 due to its small pore size and the tension of water molecules themselves. It is a conventional technical means, which is used as a "semi-permeable membrane" in the present application, and its specific structure and principle will not be displayed and described.

[0049] Further, referring to Figure 6 The distribution assembly 44 includes a distribution pipe 441 parallel to the bottom wall of the inner surface of the bottle body 1 and located at the tail end of the gas conveying pipe 41. The distribution pipe 441 is provided with branch pipes two 443 and branch pipes one 442 on the upper and lower parts of the side close to the inner wall of the bottle body 1, respectively. A plurality of uniform gas pipes 444 are fixedly connected to the upper end of the distribution pipe 441 and communicate with the branch pipes two 443 and are in close contact with the lower end of the nano filter core 42. The side of the branch pipes one 442 away from the inner wall of the bottle body 1 communicates with the driving assembly 43.

[0050] The distribution assembly 44 arranged at the tail end of the gas conveying pipe 41 is used to distribute the oxygen sent by the gas conveying pipe 41. Specifically, when the oxygen in the gas conveying pipe 41 enters the lower part of the bottle body 1, it will enter the branch pipes two 443 and the branch pipes one 442, respectively. The oxygen entering the branch pipes one 442 will finally enter the driving assembly 43 and drive the driving assembly 43 to rotate through the action of the gas flow.

[0051] The oxygen entering the branch pipes two 443 will be uniformly distributed into each uniform gas pipe 444 and pass through the nano filter core 42 to float into the water above the nano filter core 42 through the action of the uniform gas pipe 444, thereby forming bubbles in the water.

[0052] In the fourth embodiment, on the basis of the third embodiment, the branch pipes one 442, the hollow disc 432 and the wind wheel 431 are further matched to drive the wind wheel 431 to rotate by the gas flow, and drive the humidification auxiliary structure 5 to operate. The Y-shaped branch pipes 436 of the wind wheel 431 are matched with the valve 435 to make the oxygen form bubbles to enhance humidification. The tapered fan plates 53 and the spoiler 54 of the humidification auxiliary structure 5 are matched with the scale structure to scatter the bubbles and increase the gas-liquid contact area. The center ring 51, the spring sliding block two 52 and the piston rod 56 are matched to realize the cleaning of the inner wall of the bottle body 1 by the spoiler 54, and to avoid the saturation of the water body to maintain efficient humidification.

[0053] Further, referring to Figure 6 and Figure 7, the driving assembly 43 comprises a hollow disc 432 fixedly connected with the bottom wall of the inner surface of the bottle body 1, the inner cavity of the hollow disc 432 is communicated with a plurality of branch pipes 442, the inner surface of the hollow disc 432 is rotatably connected with a wind wheel 431, the upper end of the wind wheel 431 extends to the upper end of the nanofiltration core 42 through the lower end of the nanofiltration core 42 and is fixedly connected with a connecting column 433, the outer surface of the connecting column 433 is fixedly connected with a limiting disc 434 abutting the upper end of the nanofiltration core 42, and the upper end of the connecting column 433 is fixedly connected with the humidification auxiliary structure 5.

[0054] The airflow sent in through the branch pipe 442 can blow the wind wheel 431 to rotate, and then drive the connecting column 433 installed on the upper part of the wind wheel 431 to rotate, and drive the humidification auxiliary structure 5 to rotate through the action of the connecting column 433, so as to further process the bubbles.

[0055] Further, referring to Figure 7 , a plurality of Y-shaped branch pipes 436 are arranged on the central axis of the wind wheel 431, the two side branches of the plurality of Y-shaped branch pipes 436 are respectively communicated with the inner surface of the bottle body 1 through the upper end of the valve 435 and the lower part of the outer surface of the connecting column 433, and the valve 435 is arranged on the outlet of the plurality of Y-shaped branch pipes 436.

[0056] After the airflow of the branch pipe 442 enters the hollow disc 432, it will accumulate therein, and the Y-shaped branch pipe 436 arranged at the axis of the wind wheel 431 is used for releasing the oxygen, so that the oxygen moves upward along the Y-shaped branch pipe 436 and enters the water body through the valve 435, and the bubbles are also formed.

[0057] Further, referring to Figure 8 , the humidification auxiliary structure 5 comprises a central ring 51 arranged on the outer surface of the connecting column 433, a plurality of tapered fan plates 53 are fixedly connected in array on the outer surface of the central ring 51, the tapered angles of the plurality of tapered fan plates 53 are all directed to the rotating direction, the inclined surfaces of the plurality of tapered fan plates 53 are all engraved with scale structures, the sides, away from the central ring 51, of the plurality of tapered fan plates 53 are all provided with spoiler plates 54, and the sides, away from the tapered fan plates 53, of the plurality of spoiler plates 54 are all engraved with scale structures.

[0058] When the wind wheel 431 rotates under the action of the airflow, the central ring 51 will also rotate synchronously through the connecting column 433, and in this process, the central ring 51 will drive the oil delivery pipe 55 and the piston rod 56 to rotate synchronously, so as to stir the water body, and then the scale structures engraved on the surfaces of the central ring 51 can scatter the bubbles floating in the water body, so that the bubbles form more fine small bubbles, the contact area between the bubbles and the water is further increased, the water vapor dispersion rate is improved, and the humidification effect is strengthened.

[0059] Further, referring to Figure 8The inner surface of the center ring 51 is slidably connected with a spring sliding block two 52, the inner cavity of the center ring 51 is filled with glycerol, the inner cavity of the conical fan plate 53 is provided with an oil delivery pipe 55 communicated with the inner cavity of the center ring 51, the inner cavity of the oil delivery pipe 55 is slidably connected with a piston rod 56 fixedly connected with the adjacent spoiler 54, the spoiler 54 is not attached to the inner wall of the bottle body 1 when the spring sliding block two 52 is not stressed, and the spoiler 54 is attached to the inner wall of the bottle body 1 under the action of the piston rod 56 after the spring sliding block two 52 is stressed into the center ring 51.

[0060] After the air inlet cover plate 2 is taken out, a pipeline with the same diameter as the spring sliding block two 52 is used to press the spring sliding block two 52 downward to make it shrink into the center ring 51, and the glycerol in the center ring 51 is pressed to spread to the surrounding oil delivery pipe 55, and then the spoiler 54 is pushed to the inner wall of the bottle body 1 by the piston rod 56, at this time, rotating the pipeline can drive the center ring 51 to rotate by friction, so that the spoiler 54 rubs on the inner wall of the bottle body 1, and the scale structure engraved on the outer arc surface of the spoiler 54 can clean the scale or other attachments on the inner wall of the bottle body 1.

[0061] The conventional humidification equipment directly introduces oxygen into water, relies on the interaction of bubbles and water to humidify, which has very low humidification degree, and after the water saturation oxygen content, the oxygen humidification effect cannot be further increased, and even the problem of insufficient humidification may be caused;

[0062] Because when the water saturation oxygen content reaches the saturation state, the oxygen dissolution in water reaches the limit, at this time, the oxygen introduced into the water cannot be dissolved into the water, but can only escape from the water in the form of bubbles. The interaction time of these undissolved oxygen bubbles and water is very short, and the water carried is very limited, and the humidification effect almost stops. This makes it difficult to meet the human body's demand for oxygen humidification, especially for patients who need long-term oxygen inhalation. Dry oxygen may irritate the respiratory mucosa, cause discomfort, and even cause mucosal damage, thick sputum and other problems;

[0063] In the present application, the water body is stirred by the humidification auxiliary structure 5, which promotes the dispersion of oxygen and increases the contact area, and also promotes the outgassing of oxygen in the water body, avoiding water saturation, thereby continuously maintaining high-efficiency humidification effect.

[0064] Specifically, the stirring action of the humidification auxiliary structure 5 on the water body can break the oxygen introduced into the water into more small bubbles, greatly increasing the contact area of oxygen and water, and allowing more water to adhere to the bubble surface.

[0065] On the other hand, stirring breaks the static balance of the water body, promotes the mixing of the water body with a lot of dissolved oxygen with the surrounding water body with low dissolved oxygen, and accelerates the gas exchange on the surface of the water body, so that the oxygen in the water body reaches the saturation trend in time, avoiding the whole cup of water quickly entering the saturated state of dissolved oxygen.

[0066] In the fifth embodiment, the oxygen is guided into the tapered pipe 452 through the cooperation of the flow guide plate 411 of the gas delivery pipe 41 and the tapered pipe 452; the water is sucked and sprayed out of the spraying pipe 451 to form water mist through the cooperation of the tapered pipe 452, the spraying pipe 451 and the communication pipe 453, and the utilization of the Venturi effect to form negative pressure at the interface; the water mist formed by the active atomization assembly 45 and the humidified oxygen separated from the bottom are further exchanged in substance to further improve the humidity of the oxygen and improve the humidification effect.
