Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, specifically to pipeline structure and atomizing device. Background Technology
[0002] In related technologies, to facilitate drug delivery to the patient's respiratory tract, a high-flow humidified respiratory therapy device and a nebulizer module are connected via a three-way connector. The humidified gas output from the humidification tank of the high-flow humidified respiratory therapy device enters the three-way connector, and the nebulizer module also delivers the nebulized drug into the three-way connector. The nebulized drug mixes with the humidified gas and is eventually delivered to the patient's body, where the patient absorbs the drug in the mixed gas through breathing.
[0003] However, current nebulizer modules deliver high drug flow rates, resulting in high drug concentrations in the gas mixture. When patients inhale this mixture, they may experience drug overdose, leading to incomplete absorption. Unabsorbed medication is then exhaled, resulting in waste. Furthermore, the airway mucosa is susceptible to mechanical damage from the high-speed drug particles. A large amount of aerosol entering the alveoli in a short time, exceeding surface tension equilibrium, can induce pulmonary edema. This can further impair the ability of weak patients to cough up retained sputum, leading to obstruction of the secretory tract. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a pipeline structure that can increase the utilization rate of nebulized drugs.
[0005] This utility model also proposes an atomizing device having the above-mentioned pipeline structure.
[0006] According to a first aspect embodiment of the present invention, a pipeline structure is provided for connecting a humidification tank and an atomizing module, wherein the humidification tank is used to discharge humidifying gas, and the atomizing module is used to discharge atomized medication, and the pipeline structure includes:
[0007] The first connecting pipe section includes a first receiving end and a first output end, and also has a first buffer channel, wherein the first buffer channel forms a first receiving port at the first receiving end and a first output port at the first output end;
[0008] The second connecting tube section includes a second receiving end and a second output end, and also has a second buffer channel. The second receiving end is used to connect to the atomizing module; the second output end is connected to the side of the first connecting tube section and is located between the first receiving end and the first output end.
[0009] A buffer section is located at the second output end and blocks the first buffer channel and the second buffer channel. The buffer section has a buffer hole that connects the first buffer channel and the second buffer channel. The cross-sectional area of the buffer hole is smaller than the cross-sectional area of the second buffer channel.
[0010] The first buffer channel has a concave surface inside; the concave surface is recessed away from the first receiving port and is located between the first output end and the second output end in a first direction, the first direction being the direction from the first receiving end to the first output end; the first receiving port is spaced apart from the concave surface in a direction perpendicular to the first direction and is used to connect to the humidification tank, and the humidified gas discharged from the humidification tank can flow to the concave surface through the first receiving port.
[0011] The pipeline structure according to the embodiments of this utility model has at least the following beneficial effects:
[0012] Because the humidified gas discharged from the humidification tank can flow towards the concave surface through the first receiving port, the concave surface guides the contacting humidified gas to move towards the wall near the first buffer channel, and further flow in the opposite direction to the first receiving end. The humidified gas that was originally near the first receiving end continues to flow towards the concave surface along with the humidified gas flowing out of the first receiving port, thereby causing the first buffer channel to gradually accumulate humidified gas, and the gas pressure in the first buffer channel to gradually increase. When the humidified gas pressure is high enough, some of the humidified gas flowing towards the concave surface will eventually flow towards the first output port due to the gas pressure, while the remaining humidified gas will again be guided by the concave surface to flow in the opposite direction towards the first receiving end.
[0013] During the aforementioned cycle, the low-flow-rate nebulized medication flowing into the first buffer channel from the buffer orifice mixes with the humidifying gas. Since the concave surface is located between the first and second output ends, the humidifying gas, guided by the concave surface to flow in the opposite direction, contacts and mixes with the nebulized medication. Furthermore, because the humidifying gas circulates within the first buffer channel under the influence of the concave surface and the humidifying gas flowing in from the first receiving port, the nebulized medication following the humidifying gas flow also circulates with the humidifying gas, thus prolonging the flow time of the nebulized medication in the first buffer channel. This enhances the uniformity of the mixing between the nebulized medication and the humidifying gas, which helps reduce the peak concentration of the nebulized medication in the mixed gas when continuously administering medication to the patient. This reduces the likelihood of insufficient absorption of the nebulized medication during a single breath, further improving the utilization rate of the nebulized medication.
[0014] According to some embodiments of the present invention, the pipeline structure further includes a protrusion located within the first buffer channel, the protrusion being connected to the first output end and protruding toward the first receiving port; the sidewall of the protrusion and the first connecting pipe segment define an annular channel; the concave surface is located on the side of the protrusion opposite to the first direction.
[0015] According to some embodiments of the present invention, the side of the protrusion perpendicular to the first direction is provided with a guide surface, and the guide surface is spaced apart from the inner wall of the first buffer channel; the edge of the concave surface and the end of the guide surface facing away from the first direction have an arc-shaped transition surface.
[0016] According to some embodiments of the present invention, the pipeline structure has a second direction, which is the arrangement direction of the first connecting pipe segment and the second connecting pipe segment. The buffer portion includes a first connecting portion and a second connecting portion connected to each other. The first connecting portion protrudes in the second direction relative to the second connecting portion. The first connecting portion has a vent hole for connecting the first buffer channel and the second buffer channel. The sum of the cross-sectional areas of the vent hole and the buffer hole is less than the cross-sectional area of the second buffer channel.
[0017] According to some embodiments of the present invention, the buffer hole has a first buffer and a second buffer that are connected to each other, the first buffer being located at the first connecting part and the second buffer being located at the second connecting part.
[0018] According to some embodiments of the present invention, the surface of the buffer portion on the side near the first buffer channel is coplanar with the inner wall surface of the first buffer channel.
[0019] According to some embodiments of the present invention, the pipeline structure has a second direction, which is the arrangement direction of the first connecting pipe segment and the second connecting pipe segment, and the first output port is disposed on one side of the concave surface in the second direction.
[0020] According to some embodiments of the present invention, the pipeline structure has a second direction, which is the arrangement direction of the first connecting pipe segment and the second connecting pipe segment. The buffer hole is located on the side of the concave surface facing the third direction. The third direction, the second direction, and the first direction are perpendicular to each other.
[0021] According to some embodiments of the present invention, the second buffer channel is inclined toward the first output end along the direction from the second receiving end to the second output end.
[0022] The atomizing device according to a second aspect embodiment of the present invention includes:
[0023] Pipeline structure as described in any of the above embodiments;
[0024] The atomizing module has a nozzle for discharging atomized medication, the atomizing module is connected to the second receiving end, and the nozzle is connected to the second buffer channel.
[0025] The atomizing device according to the embodiments of the present utility model has at least the following beneficial effects:
[0026] Because the humidified gas discharged from the humidification tank can flow towards the concave surface through the first receiving port, the concave surface guides the contacting humidified gas to move towards the wall near the first buffer channel, and further flow in the opposite direction to the first receiving end. The humidified gas that was originally near the first receiving end continues to flow towards the concave surface along with the humidified gas flowing out of the first receiving port, thereby causing the first buffer channel to gradually accumulate humidified gas, and the gas pressure in the first buffer channel to gradually increase. When the humidified gas pressure is high enough, some of the humidified gas flowing towards the concave surface will eventually flow towards the first output port due to the gas pressure, while the remaining humidified gas will again be guided by the concave surface to flow in the opposite direction towards the first receiving end.
[0027] During the aforementioned cycle, the low-flow-rate nebulized medication flowing into the first buffer channel from the buffer orifice mixes with the humidifying gas. Since the concave surface is located between the first and second output ends, the humidifying gas, guided by the concave surface to flow in the opposite direction, contacts and mixes with the nebulized medication. Furthermore, because the humidifying gas circulates within the first buffer channel under the influence of the concave surface and the humidifying gas flowing in from the first receiving port, the nebulized medication following the humidifying gas flow also circulates with the humidifying gas, thus prolonging the flow time of the nebulized medication in the first buffer channel. This enhances the uniformity of the mixing between the nebulized medication and the humidifying gas, which helps reduce the peak concentration of the nebulized medication in the mixed gas when continuously administering medication to the patient. This reduces the likelihood of insufficient absorption of the nebulized medication during a single breath, further improving the utilization rate of the nebulized medication.
[0028] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0049] In existing technologies, high-flow-rate humidified respiratory therapy devices provide patients with humidified gas, thereby offering a stable high oxygen concentration and optimizing the patient's airway mucociliary clearance function. Building upon this approach, some technologies propose combining a three-way valve with a high-flow-rate humidified respiratory therapy device to deliver medication to the patient simultaneously with the humidified gas. Specifically, the high-flow-rate humidified respiratory therapy device generates humidified gas for the patient through a built-in humidification canister, and the nebulizer module discharges its stored medication solution to form nebulized medication. The nebulized medication and humidified gas are mixed through the three-way valve and ultimately delivered to the patient. However, because existing nebulizer modules spray nebulized medication at high flow rates, the drug concentration is often too high, hindering absorption and leading to medication waste and potential harm to the body.
[0050] In view of this, please refer to Figures 1 to 5As shown, this utility model proposes a pipeline structure 10. The pipeline structure 10 of this utility model is used to connect a humidification tank and a nebulization module, and is capable of receiving humidified gas generated by the humidification tank and nebulized medication generated by the nebulization module. Without departing from the inventive concept of this utility model, the pipeline structure 10 can also be connected to a device including a humidification tank and a nebulization module. In some embodiments, the pipeline structure 10 is connected to a high-flow respiratory humidification therapy device having a humidification tank.
[0051] Please refer to Figure 1 As shown, the pipeline structure 10 of this utility model includes a first connecting pipe section 100, a second connecting pipe section 200, and a buffer section 300.
[0052] The first connecting pipe section 100 of this utility model includes a first receiving end 110 and a first output end 120, and also has a first buffer channel 130. The first buffer channel 130 forms a first receiving port 111 at the first receiving end 110 and a first output port 121 at the first output end 120. The first receiving port 111 of this utility model is used to connect to the humidification tank, and the humidified gas discharged from the humidification tank can enter the first buffer channel 130 through the first receiving port 111.
[0053] The second connecting pipe section 200 of this invention includes a second receiving end 210 and a second output end 220, and also has a second buffer channel 230. The second receiving end 210 is used to connect to the atomizing module 20. The second output end 220 is connected to the side of the first connecting pipe section 100 and is located between the first receiving end 110 and the first output end 120. The second receiving port of this invention is used to connect to the atomizing module 20, and the atomized drug discharged by the atomizing module 20 can enter the second buffer channel 230 through the second receiving port.
[0054] The buffer section 300 of this invention is located at the second output end 220 and blocks the first buffer channel 130 and the second buffer channel 230. The buffer section 300 has a buffer hole 310 connecting the first buffer channel 130 and the second buffer channel 230; the cross-sectional area of the buffer hole 310 is smaller than the cross-sectional area of the second buffer channel 230. Since the first buffer channel 130 and the second buffer channel 230 are connected through the buffer hole 310, the atomized drug entering the second buffer channel 230 from the second receiving port can enter the first buffer channel 130 through the buffer hole 310 and mix with the humidified gas in the first buffer channel 130. However, since the cross-sectional area of the buffer hole 310 is smaller than the cross-sectional area of the second buffer channel 230, the atomized drug entering the second buffer channel 230 can be blocked by the buffer section 300 and stay in the second buffer channel 230, resulting in a lower flow rate when it flows from the buffer hole 310 into the first buffer channel 130. A mixture of humidifying gas and low-flow-rate nebulized medication will have a lower concentration of nebulized medication, thus allowing patients to fully absorb the nebulized medication during breathing.
[0055] Further, please refer to Figure 1 , Figure 2 , Figure 3 As shown, where Figure 3 This invention illustrates one form of flow of humidifying gas, atomized drug, and mixed gas within a pipeline structure. The first buffer channel 130 of this invention has a concave surface 140 inside. The concave surface 140 is recessed away from the first receiving port 111 and is located between the first output end 120 and the second output end 220 in a first direction, which is the direction from the first receiving end 110 to the first output end 120. The first receiving port 111 is spaced apart from the concave surface 140 in a direction perpendicular to the first direction and is used to connect to the humidification tank. The humidifying gas discharged from the humidification tank can flow through the first receiving port 111 to the concave surface 140.
[0056] Because the humidified gas discharged from the humidification tank can flow through the first receiving port 111 to the concave surface 140, the concave surface 140 guides the contacting humidified gas to move towards the wall of the first buffer channel 130, and further flow in the opposite direction to the first receiving end 110. The humidified gas that was originally close to the first receiving end 110 continues to flow towards the concave surface 140 along with the humidified gas flowing out of the first receiving port 111, thereby causing the first buffer channel 130 to gradually accumulate humidified gas, and the gas pressure in the first buffer channel 130 gradually increases. When the humidified gas pressure is high enough, some of the humidified gas flowing towards the concave surface 140 will eventually flow towards the first output port 121 due to the gas pressure, while the remaining humidified gas will again be guided by the concave surface 140 to flow in the opposite direction to the first receiving end 110.
[0057] During the aforementioned cycle, the low-flow-rate nebulized medication flowing into the first buffer channel 130 from the buffer orifice 310 mixes with the humidifying gas. Since the concave surface 140 is located between the first output end 120 and the second output end 220, the humidifying gas, guided by the concave surface 140 to flow in the opposite direction, contacts and mixes with the nebulized medication. Furthermore, because the humidifying gas circulates within the first buffer channel 130 under the influence of the concave surface 140 and the humidifying gas flowing in from the first receiving port 111, the nebulized medication following the humidifying gas flow also continues to circulate with it. This prolongs the time the nebulized medication flows within the first buffer channel 130, enhancing the uniformity of the mixing between the nebulized medication and the humidifying gas. This helps reduce the peak concentration of the nebulized medication in the mixed gas when continuously administering medication to the patient, thereby reducing the possibility of insufficient absorption of the nebulized medication during a single breath and further improving the utilization rate of the nebulized medication.
[0058] It should be noted that, based on the inventive concept of this utility model, those skilled in the art can design, for example... Figure 1 The tee pipe structure shown can also be achieved by sealing one of the openings of an existing four-way pipe and adjusting its internal structure accordingly. Alternatively, it can be achieved by adjusting the number of openings and internal structure of other existing pipe connectors. All pipe structures 10 derived from the inventive concept of this invention are within the protection scope of this invention.
[0059] Without departing from the inventive concept of this utility model, those skilled in the art can adjust the distance between the first receiving port 111 and the concave surface 140 according to the actual flow rate and concentration of the humidified gas flowing out of the first receiving port 111. For example, in some embodiments, the distance between the first receiving port 111 and the concave surface 140 is 40mm to 50mm.
[0060] Without departing from the inventive concept of this utility model, those skilled in the art can adjust the position of the concave surface 140. In some embodiments, the concave surface 140 is directly disposed at the first output terminal 120.
[0061] As a preferred option, please refer to Figure 1 , Figure 2As shown, in some embodiments, the pipeline structure 10 further includes a protrusion 400 located within the first buffer channel 130. The protrusion 400 is connected to the first output end 120 and protrudes towards the first receiving port 111. The sidewall of the protrusion 400 and the first connecting pipe section 100 define an annular channel 131. The concave surface 140 is located on the side of the protrusion 400 opposite to the first direction. Through the above scheme, the annular channel 131 defined between the protrusion 400 and the first connecting pipe section 100 can provide space for storing gas, thereby prolonging the time that the humidifying gas stays in the first buffer channel 130 and further enhancing the uniformity of mixing between the atomized drug and the humidifying gas.
[0062] For details, please refer to Figure 3 As shown, when the gas pressure between the concave surface 140 and the first receiving section is large, the mixed gas will first enter the annular channel 131, then flow around the side of the protrusion 400 to the first output port 121, and finally flow into the patient's body. The flow of the mixed gas in the annular channel 131 prolongs its own flow time in the first buffer channel 130, and the nebulized drug and the humidifying gas can be mixed more evenly.
[0063] On the other hand, as mentioned above, those skilled in the art can set the distance between the first receiving port 111 and the concave surface 140. In conjunction with the above solution, the art can further adjust the protrusion length of the protrusion 400 so that the length of the annular channel 131 is extended while the distance between the concave surface 140 and the first receiving port 111 remains unchanged, thereby further increasing the flow time of the mixed gas in the annular channel 131 and making the atomized drug and the humidified gas more evenly mixed.
[0064] Further, please refer to Figure 1 , Figure 2 , Figure 3 As shown, in some embodiments, the protrusion 400 has a guide surface 410 on its side perpendicular to the first direction, and the guide surface 410 is spaced apart from the inner wall of the first buffer channel 130; the edge of the concave surface 140 and the end of the guide surface 410 facing away from the first direction have an arc-shaped transition surface 420. With the above scheme, a portion of the mixed gas guided by the concave surface 140 can flow along the concave surface 140 and continue to flow along the arc-shaped transition surface 420 to the guide surface 410 under the influence of the Coanda effect. The mixed gas can more easily flow from the concave surface 140 into the annular channel 131, so that the mixed gas can further utilize the space of the annular channel 131 for flow, the flow time of the humidified gas is longer, and the atomized drug and the humidified gas are mixed more evenly.
[0065] Without departing from the inventive concept of this utility model, those skilled in the art can adjust the structure of the buffer part 300.
[0066] For example, please refer to Figure 1 , Figure 4 As shown, in some embodiments, the surface of the buffer section 300 near the first buffer channel 130 is coplanar with the inner wall surface of the first buffer channel 130. Through this design, the buffer section 300 provides flow space for the humidifying gas, allowing it to flow more smoothly along the inner wall of the first buffer channel 130 towards the first receiving end 110. This makes it easier for the humidifying gas to approach the first receiving end 110 and flow in the opposite direction with the humidifying gas flowing out of the first receiving port 111. This helps to prolong the circulation time of the humidifying gas within the first buffer channel 130, thereby resulting in a more uniform mixture between the humidifying gas and the atomized drug.
[0067] As a preferred method, please refer to Figure 1 , Figure 4 As shown, in some embodiments, the pipeline structure 10 has a second direction, which is the arrangement direction of the first connecting pipe segment 100 and the second connecting pipe segment 200. The buffer portion 300 includes a first connecting portion 320 and a second connecting portion 340 connected to each other. The first connecting portion 320 protrudes in the second direction relative to the second connecting portion 340. The first connecting portion 320 has a vent 330 for connecting the first buffer channel 130 and the second buffer channel 230. The sum of the cross-sectional areas of the vent 330 and the buffer hole 310 is less than the cross-sectional area of the second buffer channel 230.
[0068] Since the sum of the cross-sectional areas of the vent 330 and the buffer hole 310 is less than the cross-sectional area of the second buffer channel 230, the atomized drug entering the second buffer channel 230 can be blocked by the buffer part 300 and remain in the second buffer channel 230. Furthermore, since the atomized drug flows from the second connecting pipe section 200 towards the first connecting pipe section 100, that is, the atomized drug flows in the opposite direction of the second direction, during the process of the atomized drug flowing from the second buffer channel 230 into the buffer hole 310, some droplets in the atomized drug condense into water droplets on the surface of the buffer part 300 near the second buffer channel 230 when blocked by the buffer part 300.
[0069] With the above solution, since the first connecting part 320 protrudes in the second direction relative to the second connecting part 340, the water droplets condensed on the first connecting part 320 will be pushed by the atomized drug flowing in the opposite direction to the second direction and flow along the surface of the buffer part 300 to the second connecting part 340. This allows the vent 330 located in the first connecting part 320 to maintain communication between the first buffer channel 130 and the second buffer channel 230. The atomized drug located in the second buffer channel 230 can continuously enter the first buffer channel 130 through the vent 330 and mix with the humidifying gas, so that the atomized drug mixes more stably with the humidifying gas during the continuous delivery to the second buffer channel 230.
[0070] Based on the above solutions, please refer to Figure 4 , Figure 5 As shown, in some embodiments, the buffer hole 310 has a first buffer zone 311 and a second buffer zone 312 that are connected. The first buffer zone 311 is located at the first connecting portion 320, and the second buffer zone 312 is located at the second connecting portion 340. With the above solution, since the first connecting portion 320 protrudes in the second direction relative to the second connecting portion 340, the water droplets condensed in the buffer portion 300 and blocking the buffer hole 310 will be pushed in the opposite direction of the atomized drug in the second direction, so that a portion of the water droplets blocking the buffer hole 310 will flow from the first buffer zone 311 to the second buffer zone 312, thereby keeping the first buffer zone 311 connected to the second buffer channel 230. The atomized drug located in the second buffer channel 230 can continuously enter the first buffer channel 130 through the first buffer zone 311 and mix with the humidifying gas, so that the atomized drug is more stably mixed with the humidifying gas during the continuous delivery to the second buffer channel 230.
[0071] Further, please refer to Figure 1 , Figure 2 As shown, in some embodiments, the pipeline structure 10 has a second direction, which is the arrangement direction of the first connecting pipe section 100 and the second connecting pipe section 200. The first output port 121 is disposed on one side of the concave surface 140 in the second direction. With the above scheme, when the first connecting pipe section 100 is placed at the bottom, since the first output port 121 is located on one side of the concave surface 140 in the second direction, the water droplets condensed during the mixing process of the humidifying gas and the atomized drug will preferentially move in the opposite direction of the second direction, and then gather on the side of the first buffer channel 130 away from the first output port 121, delaying the water droplets from clogging the first output port 121, which is beneficial for the mixed gas to flow out stably from the first output port 121.
[0072] As previously described, the scheme of forming an annular channel 131 using the protrusion 400 and the inner wall of the first buffer channel 130 is combined with the above scheme. When the pipeline structure 10 tilts due to an accident, the side of the protrusion 400 can also block some of the condensate in the annular channel 131, thereby reducing the possibility of condensate accidentally entering the first outlet 121, which is conducive to making the mixed gas flow out from the first outlet 121 more stably.
[0073] Further, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, the pipeline structure 10 has a second direction, which is the arrangement direction of the first connecting pipe section 100 and the second connecting pipe section 200. The buffer hole 310 is located on the side of the concave surface 140 facing the third direction. The third direction, the second direction and the first direction are perpendicular to each other.
[0074] With the above solution, since the buffer hole 310 is located on the third-direction upward side of the concave surface 140, the flow direction of the atomized drug flowing out of the buffer hole 310 is offset from the flow direction of the humidifying gas flowing towards the concave surface 140. The atomized drug flowing out of the buffer hole 310 will have more sufficient contact with the humidifying gas flowing towards the first receiving end 110, while reducing the contact between the atomized drug and the humidifying gas flowing towards the concave surface 140. This allows the humidifying gas flowing out of the first receiving port 111 to flow more stably into the concave surface 140, and after being guided by the concave surface 140, it will continuously provide humidifying gas flowing towards the first receiving end 110. The humidifying gas flowing towards the first receiving end 110 can be more fully mixed with the atomized drug, and the stability of the mixing process between the humidifying gas and the atomized drug is further improved.
[0075] Further, please refer to Figure 1 , Figure 3 As shown, in some embodiments, the second buffer channel 230 is inclined toward the first output terminal 120 along the direction from the second receiving end 210 to the second output terminal 220. With this scheme, the atomized drug flowing into the second buffer channel 230 will also flow into the first buffer channel 130 from the buffer hole 310 in the inclined direction of the second buffer channel 230, and will have a velocity component toward the first output terminal 120. Therefore, the atomized drug flowing into the first buffer channel 130 will slow down the flow of the humidifying gas flowing toward the first receiving end 110 in the first buffer channel 130, thereby prolonging the flow time of the humidifying gas in the first buffer channel 130, which is beneficial for more thorough mixing of the atomized drug and the humidifying gas.
[0076] Please refer to Figure 3 As shown, in some embodiments, the tubing structure 10 further includes a plug 500, which is detachably connected to the second receiving end 210, so that the nebulizing module 20 can be connected to the second receiving end 210, or the second receiving end 210 can be closed. With this solution, when the nebulizing module 20 is not needed to provide nebulized medication, the plug 500 can be connected to the second receiving end 210, allowing the first output port 121 of the tubing structure 10 to provide humidifying gas to the patient independently.
[0077] Based on the above solution, in some embodiments, the plug 500 is integrally connected to the first connecting pipe section 100. The above solution can further prevent the plug 500 from being lost when separated from the second receiving end 210, and the user does not need to search for the plug 500 when needed, increasing the usability of the pipe structure 10.
[0078] Please refer to Figures 1 to 6 As shown, this utility model also proposes an atomizing device, including an atomizing module 20 and a pipeline structure 10 as described in any of the above embodiments. The atomizing module 20 has a nozzle 21 for discharging atomized medication, the atomizing module 20 is connected to a second receiving end 210, and the nozzle 21 is connected to a second buffer channel 230.
[0079] The nebulizer module 20 discharges nebulized medication into the second buffer channel 230 through the nozzle 21. Since the first buffer channel 130 and the second buffer channel 230 are connected by a buffer hole 310, the nebulized medication entering the second buffer channel 230 from the second receiving port can enter the first buffer channel 130 through the buffer hole 310 and mix with the humidified gas in the first buffer channel 130. Because the cross-sectional area of the buffer hole 310 is smaller than that of the second buffer channel 230, the nebulized medication entering the second buffer channel 230 can be blocked by the buffer section 300 and remain in the second buffer channel 230, resulting in a lower flow rate when it flows from the buffer hole 310 into the first buffer channel 130. The mixed gas formed by the humidified gas and the low-flow-rate nebulized medication has a lower concentration of nebulized medication, thus allowing the patient to fully absorb the nebulized medication during breathing.
[0080] Furthermore, since the humidified gas discharged from the humidification tank can flow through the first receiving port 111 to the concave surface 140, the concave surface 140 guides the contacting humidified gas to move towards the wall of the first buffer channel 130, and further flow in the opposite direction to the first receiving end 110. The humidified gas that was originally close to the first receiving end 110 continues to flow towards the concave surface 140 along with the humidified gas flowing out of the first receiving port 111, thereby causing the first buffer channel 130 to gradually accumulate humidified gas, and the gas pressure in the first buffer channel 130 gradually increases. When the humidified gas pressure is high enough, some of the humidified gas flowing towards the concave surface 140 will eventually flow towards the first output port 121 due to the gas pressure, while the remaining humidified gas will again be guided by the concave surface 140 to flow in the opposite direction to the first receiving end 110.
[0081] During the aforementioned cycle, the low-flow-rate nebulized medication flowing into the first buffer channel 130 from the buffer orifice 310 mixes with the humidifying gas. Since the concave surface 140 is located between the first output end 120 and the second output end 220, the humidifying gas, guided by the concave surface 140 to flow in the opposite direction, contacts and mixes with the nebulized medication. Furthermore, because the humidifying gas circulates within the first buffer channel 130 under the influence of the concave surface 140 and the humidifying gas flowing in from the first receiving port 111, the nebulized medication flowing with the humidifying gas also circulates with it, thus prolonging the flow time of the nebulized medication within the first buffer channel 130. This enhances the uniformity of the mixing between the nebulized medication and the humidifying gas, which helps reduce the peak concentration of the nebulized medication in the mixed gas when continuously administering medication to the patient. This reduces the likelihood of insufficient absorption of the nebulized medication during a single breath, further improving the utilization rate of the nebulized medication.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
