Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more particularly to a buoy-type oxygen inhaler for nebulization. Background Technology

[0002] The buoy-type oxygen inhaler is a buoy-type oxygen flow regulating device that integrates humidification and nebulization modes. It belongs to Class II medical devices. The inhaler is mainly a central oxygen supply wall plug type, and there are also a few cylinder types. In oxygen inhalation mode, oxygen enters the humidification cup through the flow meter for humidification, and then is inhaled through the oxygen delivery tube connected to the nasal cannula or mask. In nebulization mode, oxygen bypasses the humidification water and directly outputs high-pressure, high-speed airflow. It is connected to an external airflow nebulizer cup to drive the nebulization of the drug solution. It is used for nebulized inhalation therapy for bronchial asthma, COPD, bronchitis, etc.

[0003] When an inhaler is used for humidification therapy, oxygen needs to be dispersed into tiny bubbles through porous cotton before entering the water in the humidification cup to improve the humidification effect. However, during this process, the bubbles burst on the water surface, forming splashing droplets. If these droplets enter the oxygen delivery tube, water will accumulate inside the tube. To prevent patients from inhaling this water into their nasal cavity, the oxygen delivery tube needs to be replaced. To prevent this from happening, existing inhalers usually set the maximum water level in the humidification cup very low. However, this requires frequent refilling and opening of the humidification cup, increasing the probability of contamination of the water inside. Summary of the Invention

[0004] In order to overcome the disadvantages mentioned in the background art, the present invention provides a float-type oxygen inhaler for nebulization.

[0005] The technical solution is as follows: A buoy-type oxygen inhaler for nebulization, comprising a flow meter, wherein the flow meter is provided with an air inlet, a nebulizing tube, a switching button and an adjustment knob, the air inlet is connected to the nebulizing tube, the flow meter is detachably mounted with a humidification cup, the humidification cup is fixedly connected to an oxygen inhalation tube, both the nebulizing tube and the oxygen inhalation tube are used to connect to an oxygen delivery tube, the humidification cup is fixedly connected to an air inlet tube, the air inlet tube is connected to the air inlet, the lower side of the air inlet tube is provided with porous cotton, and the humidification cup is provided with a first baffle plate, a second baffle plate and a third baffle plate arranged sequentially from the outside to the inside, the first baffle plate, the second baffle plate and the third baffle plate are connected by a plurality of first connectors and a plurality of second connectors.

[0006] Furthermore, the first baffle, the second baffle, and the third baffle are all frustum rings, and the projections of the first baffle, the second baffle, and the third baffle on the horizontal plane overlap between adjacent projections. At the same time, the diameter of the lower side of each of the three baffles is larger than the diameter of the upper side of each of them.

[0007] Furthermore, the first baffle, the second baffle, and the third baffle are each provided with two water guide grooves on the upper and lower sides. The third baffle is fixedly connected to a guide pipe, the inner diameter of which is larger than the outer diameter of the air inlet pipe. The air inlet pipe passes through the guide pipe. The cross-sections of the first connector and the second connector are both U-shaped, used to connect the corresponding water guide grooves. The inner side of the first connector is connected to the guide pipe. The third baffle is provided with several through holes, and the water guide groove on the upper side of the third baffle is connected to the guide pipe through the through holes.

[0008] Furthermore, the air intake pipe is fixedly connected to a flow guide shroud, which is located between the porous cotton and the flow guide pipe. The diameter of the flow guide shroud on the side closer to the flow guide pipe is larger than the diameter of the flow guide pipe.

[0009] Furthermore, a cutting mesh is provided inside the humidification cup, which is used to cut air bubbles.

[0010] Furthermore, a plurality of first floats are fixed to the upper side of the cutting net, and the maximum buoyancy generated by all the first floats is greater than the sum of the weight of all the first floats and the weight of the cutting net.

[0011] Furthermore, the oxygen inhalation tube is rotatably connected to a rotating component, the rotating component is hinged to a connecting rod, and the connecting rod is fixed to a cover plate and a second float. The cover plate is used to seal the oxygen inhalation tube.

[0012] Furthermore, the mass of the second float is greater than the mass of the cover plate.

[0013] Furthermore, the side of the third baffle plate closest to the oxygen inhalation tube is made of an elastic material, which is used to seal the oxygen inhalation tube.

[0014] Furthermore, a weight is fixed to the side of the rotating component near the connecting rod.

[0015] The present invention has the following advantages: The present invention uses a first baffle, a second baffle, and a third baffle to block the droplets generated when the bubbles burst on the water surface in the humidification cup, thereby reducing the probability of the droplets entering the oxygen supply tube through the oxygen inhalation tube, thus allowing more humidification water to be stored in the humidification cup, reducing the frequency of adding water to the humidification cup, and reducing the probability of the water in the humidification cup being contaminated.

[0016] By setting water guide channels on both the upper and lower sides of the first, second, and third baffles, the water adhering to the first, second, and third baffles will not flow to the edges of the three baffles and then fly out again as droplets with the airflow.

[0017] The cutting net cuts the bubbles, making them smaller, thereby reducing droplet splashing and noise when the bubbles burst. At the same time, the first float keeps the cutting net on the water surface to ensure the cutting effect.

[0018] When the humidification cup is tilted, the water level rises to raise the second float, which in turn causes the cover plate to block the oxygen inhalation tube. This reduces the probability of water from the humidification cup entering the oxygen delivery tube through the oxygen inhalation tube when the cup is tilted, thereby reducing the need to replace the oxygen delivery tube and minimizing wear and tear on medical equipment.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0022] Example 1

[0023] Nebulizer-type oxygen inhaler, such as Figures 1-5As shown, the device includes a flow meter 1, which has an air inlet 101, an atomizing tube 102, a switching button 103, and an adjustment knob 104. The air inlet 101 is connected to the atomizing tube 102. A humidification cup 2 is detachably installed on the flow meter 1. These are all existing devices and will not be described in detail here. The humidification cup 2 is equipped with an oxygen inhalation tube 201, both ends of which extend beyond the cup wall of the humidification cup 2. Both the atomizing tube 102 and the oxygen inhalation tube 201 are used to connect to the oxygen delivery tube. An air inlet pipe 3 is fixedly connected to the humidification cup 2 and is connected to the air inlet 101. A porous cotton is provided on the lower side of the air inlet pipe 3. 4. The humidification cup 2 is provided with a first baffle 5, a second baffle 6 and a third baffle 7 arranged sequentially from the outside to the inside. The first baffle 5 is in contact with the humidification cup 2. The size of the first baffle 5, the second baffle 6 and the third baffle 7 gradually decreases from the outside to the inside, but the three are similar in shape. The first baffle 5, the second baffle 6 and the third baffle 7 are all used to block the droplets generated when the water bubbles on the water surface in the humidification cup 2 burst, and to allow the humidified oxygen to pass through normally. The first baffle 5, the second baffle 6 and the third baffle 7 are connected by a number of first connectors 8 and a number of second connectors 9. The first baffle 5, the second baffle 6, and the third baffle 7 are all frustum rings, which allows droplets attached to the lower sides of the three to flow down the annular inclined surfaces of the three. Furthermore, the projections of the first baffle 5, the second baffle 6, and the third baffle 7 on the horizontal plane overlap between adjacent projections, thereby reducing the probability of droplets passing through the gaps between the three and increasing the success rate of the three in intercepting droplets. At the same time, the diameter of the lower side of each of the three is larger than the diameter of the upper side.

[0024] like Figures 2-6As shown, the first baffle 5, the second baffle 6, and the third baffle 7 are each equipped with two water guide channels 10 on the upper and lower sides. The water guide channels 10 are used to collect water adhering to the three baffles and prevent droplets from flowing to the edges of the three baffles and being torn apart by the airflow, generating small secondary droplets that are directly carried away by the airflow. The third baffle 7 is fixedly connected to a guide pipe 11. The inner diameter of the guide pipe 11 is larger than the outer diameter of the air inlet pipe 3. The air inlet pipe 3 passes through the guide pipe 11. The first connector 8 and the second connector 9 both have a U-shaped cross section, used to connect the corresponding water guide channels 10. The first connecting piece 8 on the inner side is connected to the guide pipe 11. The third baffle plate 7 is provided with several through holes. The water guide groove 10 on the upper side of the third baffle plate 7 is connected to the guide pipe 11 through the through holes, so that the droplets blocked by the first baffle plate 5, the second baffle plate 6 and the third baffle plate 7 flow into the guide pipe 11 and return to the water in the humidification cup 2. The height of the lower side of the first baffle plate 5, the second baffle plate 6 and the third baffle plate 7 decreases in sequence to facilitate the flow of droplets from the first connecting piece 8 and the second connecting piece 9 between adjacent pieces. The air inlet pipe 3 is fixedly connected to the guide hood 12, which is located between the porous cotton 4 and the guide pipe 11. The diameter of the side of the guide hood 12 closest to the guide pipe 11 is larger than the diameter of the guide pipe 11, so that the air bubbles generated at the porous cotton 4 will not enter the guide pipe 11, and thus the droplets flowing into the guide pipe 11 will not be blown up by the airflow again.

[0025] During the oxygen inhalation process using this device, water is first added to the humidification cup 2 until it is below the third baffle plate 7. Oxygen then enters through the inlet 101, then into the inlet tube 3, and is dispersed into bubbles by the porous cotton 4. These bubbles then enter the water in the humidification cup 2, where they are humidified before being discharged through the oxygen tubing 201, thus providing oxygen to the patient. During this process, when the bubbles burst from the water surface, they form tiny droplets. These droplets are blocked by the first baffle plate 5, the second baffle plate 6, and the third baffle plate 7, preventing them from entering the oxygen tubing 201 and ensuring normal oxygen inhalation. This prevents droplets from entering the patient's nasal cavity with the airflow and causing discomfort. Furthermore, the droplets adhere to the first baffle plate 5, the second baffle plate 6, and the third baffle plate 7. After passing through the third baffle plate 7, the droplets will flow along the first baffle plate 5, the second baffle plate 6, and the third baffle plate 7 to the lower water guide trough 10. At the same time, due to the presence of the upper and lower water guide troughs 10, the droplets attached to the first baffle plate 5, the second baffle plate 6, and the third baffle plate 7 will not flow to the edges of the three baffle plates and will form small secondary droplets under the action of airflow. The droplets attached to the first baffle plate 5, the second baffle plate 6, and the third baffle plate 7 will converge into the lower water guide trough 10 and then be guided into the guide pipe 11 through several first connectors 8. Then they will flow back into the water in the humidification cup 2. Because the guide cover 12 blocks the air bubbles generated by the porous cotton 4, there will be no airflow in the guide pipe 11. There is no need to worry about the airflow blowing up the water flowing into the guide pipe 11.

[0026] Example 2

[0027] Based on Example 1, such as Figure 2 As shown, a cutting mesh 13 is installed inside the humidification cup 2. The cutting mesh 13 has dense mesh openings to cut large bubbles into smaller bubbles, thereby reducing the height of droplets when bubbles burst and reducing the noise generated during bubble bursting. Several first floats 14 are fixed to the upper side of the cutting mesh 13. The maximum buoyancy generated by all the first floats 14 is greater than the sum of the weight of all the first floats 14 and the weight of the cutting mesh 13, thus keeping the cutting mesh 13 at the water surface. After the bubbles are cut and reduced in size, they are less likely to recombine into large bubbles, maintaining the optimal cutting effect of the cutting mesh 13 on the bubbles.

[0028] Example 3

[0029] Based on Example 2, such as Figure 2 and Figure 7 As shown, the portion of the oxygen inhalation tube 201 located inside the humidification cup 2 is rotatably connected to a rotating component 15. The rotating component 15 is hinged to a connecting rod 16, and the connecting rod 16 is fixedly connected to a cover plate 17 and a second float 18. The cover plate 17 is used to seal the oxygen inhalation tube 201. After the humidification cup 2 is tilted, the liquid level inside the humidification cup 2 lifts the second float 18, which in turn drives the cover plate 17 to seal the oxygen inhalation tube 201, thereby reducing the probability of water entering the oxygen delivery tube through the oxygen inhalation tube 201. The third baffle 7, with its side near the oxygen inhalation tube 201 made of elastic material, is used to seal the oxygen inhalation tube 201, improving the sealing performance between the two. A weight 19 is fixedly connected to the side of the rotating component 15 near the connecting rod 16, ensuring that regardless of the angle at which the humidification cup 2 is tilted, the second float 18 remains in a downward position, contacting the water surface before the oxygen inhalation tube 201, and promptly driving the cover plate 17 to seal the oxygen inhalation tube 201.

[0030] During normal use, the second float 18 falls under the influence of gravity and comes into contact with the humidification cup 2. At this time, the cover plate 17 releases the blockage on the oxygen supply tube 201, and the airflow enters the oxygen supply tube 201 normally. If the humidification cup 2 is accidentally tilted, the weight 19 drives the rotating part 15 to rotate under the influence of gravity, keeping the second float 18 in a drooping state. Then, the water surface comes into contact with the second float 18, causing the second float 18 to float. When the second float 18 floats, it drives the connecting rod 16 to rotate. The connecting rod 16 drives the cover plate 17 to block the oxygen supply tube 201, thereby reducing the probability of water in the humidification cup 2 entering the oxygen supply tube after the humidification cup 2 is tilted. This reduces the need to replace the oxygen supply tube due to water ingress, thus reducing the consumption of the oxygen supply tube.
