Description

Technical Field

[0001] The present invention relates to the technical field related to atomizers in medical devices, and in particular to a nebulizer capable of adaptively emitting mist in synchronization with breathing. Background Art

[0002] As a common medical device, nebulizers play a vital role in the treatment of respiratory diseases and are widely used in the treatment of a variety of conditions, including asthma, chronic obstructive pulmonary disease (COPD), and bronchitis. However, traditional nebulizers typically employ a continuous atomization method, continuously atomizing the medication into tiny particles for inhalation throughout the patient's breathing cycle. While this design can deliver medication to the patient's respiratory tract to a certain extent, it presents numerous issues in practical applications, limiting its therapeutic effectiveness and the patient experience.

[0003] First, traditional nebulizers continue to deliver aerosolized medication during patient exhalation, which not only prevents a significant amount of medication from being effectively absorbed but also results in significant drug waste. Statistics show that the drug utilization rate of traditional nebulizers is typically less than 30%, meaning that over 70% of the medication is not effectively utilized. This not only increases the financial burden on patients but also potentially wastes drug resources. Second, the continuously aerosolized medication enters the patient's mouth and throat during exhalation, causing significant irritation and leading to discomfort such as coughing and choking. This discomfort not only reduces treatment compliance but may also further impair respiratory function, a problem particularly prominent in sensitive populations such as children and the elderly. Furthermore, the medication cannot be effectively absorbed during exhalation, with some deposited in the mouth or throat. This not only reduces the drug's lung deposition rate but can also cause oral and throat infections, further compromising treatment effectiveness. Studies have shown that the lung deposition rate of traditional nebulizers is typically less than 10%, meaning that a significant portion of the medication fails to reach the target site, severely impacting treatment effectiveness. Summary of the Invention

[0004] The purpose of the present invention is to provide a nebulizer with adaptive breathing synchronous mist output, aiming to improve the utilization rate of medicine, increase the comfort of patients and enhance the treatment effect.

[0005] To achieve the above object, the technical solution adopted by the present invention is: to provide a nebulizer with adaptive breathing synchronous mist output, comprising: a nebulizer body and a nebulizing mask connected to the nebulizer body; The atomizer body includes an exhaust channel, an atomizing assembly, a sensing structure, and a control structure. The atomizing assembly is connected to the atomizing mask through the exhaust channel. The sensing structure is arranged in the control structure and is electrically connected to the atomizing assembly. The control structure is arranged on one side of the exhaust channel and is used to control the on / off of the exhaust channel. The exhaust channel includes an air supply channel connected to the atomizer assembly and a retractable channel arranged in the middle section of the air supply channel. The retractable channel can be driven by negative pressure to slide relative to the atomizer mask. The negative pressure is generated by the patient's inhalation action through the atomizer mask. One end of the control structure is connected to the retractable channel, and the other end is connected to the air supply channel. When the retractable channel is driven to slide, the control structure is driven to release the pressure on the air supply channel. The sensing structure senses the movement of the control structure and sends a sensing signal to the atomizer assembly when the corresponding movement is detected, so that the atomizer assembly starts atomizing according to the sensing signal. Furthermore, the control structure includes a follower assembly connected to the atomizing mask, a pressure assembly connected to the atomizing assembly, and a connecting assembly connecting the follower assembly and the pressure assembly. The follower assembly is adsorbed and moves toward the atomizing mask along with the retractable channel. The connecting assembly transmits the linear motion of the follower assembly to the rotational motion of the pressure assembly to drive the pressure assembly to compress the air delivery channel, that is, the connecting assembly converts the linear displacement of the lever into a change in the rotational angle of the driving disk through the articulated cooperation of the connecting rod and the rotating rod.

[0006] Furthermore, the follower assembly includes a lever and a spring arranged on the outside of the atomizing mask, one end of the lever is connected to the telescopic channel, and the other end of the lever is connected to the pressure-applying assembly through the connecting assembly.

The spring is used for moving and resetting the lever.

[0007] Furthermore, the connecting assembly includes a bracket, a connecting rod hingedly connected to the lever, and a rotating rod connected to the pressure assembly. The two ends of the bracket are respectively connected to the nebulizer body and the atomizing mask. The rotating rod and the connecting rod are hingedly connected at the ends close to each other. When the connecting rod swings with the lever, the connecting rod can drive the rotating rod and the pressure assembly to rotate.

[0008] Furthermore, the connection structure also includes a limiting portion for limiting the rotation of the rotating rod.

[0009] Furthermore, a limit plate is provided on one end of the bracket close to the atomizing mask, and the limit plate is located on one side of the hinged end of the connecting rod and the rotating rod. When the connecting rod drives the rotating rod to rotate, the limit plate is used to limit the angle range in which the rotating rod can rotate.

[0010] Furthermore, the pressure-applying assembly includes a support plate arranged at the end of the atomizer body, and a drive plate rotatably arranged inside the support plate. The end of the rotating rod passes through the support plate and is connected to the drive plate, and drives the drive plate to rotate within the support plate. The support plate is provided with an avoidance groove for the drive plate to rotate, and a support platform that cooperates with the drive plate to compress the gas delivery channel. The gas delivery channel passes through the support plate and is accommodated on the support platform. The drive plate is driven to rotate to compress and block the gas delivery channel.

[0011] Furthermore, the sensing structure includes a detection sensor for detecting the movement of the driving disk.

[0012] Furthermore, the atomization assembly includes an electric control board and an atomization sheet electrically connected to the electric control board.

[0013] Furthermore, a limiting ring is provided on the telescopic channel, and two limiting rings are provided, and the two limiting rings are respectively provided on the inner and outer sides of the atomizing mask to limit the telescopic range of the telescopic channel.

During exhalation, the negative pressure disappears, the retractable channel resets, the control structure compresses the air supply channel, the sensor structure senses and sends a signal, and the atomizer assembly stops atomization. This design synchronizes the device with the patient's breathing, improving drug utilization, reducing waste, and increasing patient comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by this embodiment more clearly understood, this embodiment is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this embodiment and are not intended to limit this embodiment.

[0019] Please also refer to Figures 1 to 8 The following describes a nebulizer with adaptive breathing-synchronized mist output provided by this embodiment. The nebulizer with adaptive breathing-synchronized mist output in this embodiment includes a nebulizer body 1 and a mist mask 2 connected to the nebulizer body 1. The nebulizer body 1 is provided with a connecting sleeve for connecting to the mist mask 2, and a control structure 5 is disposed within the connecting sleeve.

[0020] Among them, the atomizer body 1 includes an exhaust channel 3, an atomizing component 4, a sensing structure and a control structure 5. The atomizing component 4 is connected to the atomizing mask 2 through the exhaust channel 3. The sensing structure is arranged in the control structure 5 and is electrically connected to the atomizing component 4. The control structure 5 is arranged on one side of the exhaust channel 3 and is used to control the on and off of the exhaust channel 3.

[0021] In addition, the exhaust channel 3 includes an air supply channel 31 connected to the atomizing assembly 4 and a retractable channel 32 arranged in the middle section of the air supply channel 31. The retractable channel 32 can be driven by negative pressure to slide relative to the atomizing mask 2. The negative pressure is generated by the patient's inhalation action through the atomizing mask 2. One end of the control structure 5 is connected to the retractable channel 32, and the other end is connected to the air supply channel 31. When the retractable channel 32 is driven to slide, the control structure 5 is driven to release the pressure on the air supply channel 31. The sensing structure senses the movement of the control structure 5, and sends a sensing signal to the atomizing assembly 4 when the corresponding movement is detected, so that the atomizing assembly 4 starts to atomize according to the sensing signal.

[0022] The nebulizer of this embodiment is an adaptive breathing synchronized mist discharge device. Through an innovative design, it achieves synchronization with the patient's breathing, significantly improving the effect of nebulization treatment and the patient's user experience. Specifically, the nebulizer includes a nebulizer body 1 and an atomizing mask 2 connected to the nebulizer body 1. The nebulizer body 1 is provided with an exhaust channel 3, an atomizing assembly 4, a sensing structure and a control structure 5. The atomizing assembly 4 is connected to the atomizing mask 2 through the exhaust channel 3. The sensing structure is arranged in the control structure 5 and is electrically connected to the atomizing assembly 4. The control structure 5 is arranged on one side of the exhaust channel 3 for controlling the on and off of the exhaust channel 3.

[0023] The exhaust channel 3 includes an air supply channel 31 and a retractable channel 32. The retractable channel 32 can be driven by negative pressure to slide relative to the atomizing mask 2. When the patient inhales, the negative pressure generated within the mask causes the retractable channel 32 to slide, triggering the control structure 5 to release the pressure on the air supply channel 31, thus clearing the air supply channel 31. At this point, the sensing structure senses the movement of the control structure 5 and sends a sensing signal to the atomizing assembly 4. Upon receiving the signal, the atomizing assembly 4 begins atomizing, atomizing the liquid medicine into tiny particles that are delivered to the atomizing mask 2 through the air supply channel 31 for inhalation by the patient.

[0024] When the patient exhales, the negative pressure disappears, and the retractable channel 32 resets under the action of the spring 512 or other elastic element. The control structure 5 then resets and re-compresses the gas delivery channel 31, blocking the flow of gas. The sensing structure again senses the movement of the control structure 5 and sends a signal to the atomizer assembly 4. Upon receiving the signal, the atomizer assembly 4 stops atomizing, preventing the continued delivery of liquid medicine during the patient's exhalation, reducing drug waste and preventing unnecessary inhalation.

[0025] This design not only improves drug utilization and reduces waste, but also significantly enhances patient comfort. By precisely controlling the timing of atomization and de-atomization, the drug is effectively absorbed during the patient's inhalation, avoiding the respiratory irritation caused by atomized drug during the exhalation phase of traditional nebulizers and reducing patient discomfort. Furthermore, this adaptive respiratory synchronization function enhances treatment effectiveness, ensuring more effective drug deposition in the lungs, thereby improving the overall effectiveness of aerosol therapy.

[0026] Based on the overall description of the above structure, an exemplary structure of a nebulizer with adaptive breathing synchronous mist output in this embodiment is as follows: Figures 2 to 4 As shown. The exhaust channel 3 includes an air supply channel 31 and a retractable channel 32 disposed on the air supply channel 31. The air supply channel 31 can be made of a rubber hose commonly used in the existing medical field, which has a certain degree of softness and toughness. The air supply channel 31 is composed of a first section of rubber hose. One end of the first section of rubber hose is inserted into the nebulizer body 1 and connected to the nebulizer assembly 4, and the other end is connected to the retractable channel 32. At the same time, the retractable channel 32 can be composed of a bellows 321 and a second section of rubber channel. One end of the bellows 321 is connected to the rubber hose, and the other end is connected to the second section of rubber hose. The other end of the second section of rubber hose passes through the nebulizer mask 2 and enters the inside, and can slide relative to the nebulizer mask 2. The end of the bellows 321 near the second section of rubber hose is connected to the control structure 5. When the second section of rubber hose moves under pressure, the end of the bellows 321 moves accordingly, driving the control structure 5 to produce corresponding movement, thereby facilitating the smooth progress of subsequent processes.

[0027] Wherein, in order to prevent the second section of the rubber hose from coming out from the atomizing mask 2, it is preferred that Figure 2 and Figure 4 As shown, a limit ring 6 is provided on the telescopic channel 32, and two limit rings 6 are provided, and the two limit rings 6 are respectively provided on the inner and outer sides of the atomizing mask 2 to limit the telescopic range of the telescopic channel 32. Specifically, two limit rings 6 are respectively provided on the second section of the rubber hose, which not only ensures that the movement of the telescopic channel 32 is within a predetermined range, avoids damage to the equipment caused by excessive telescopic expansion, but also further enhances the stability and reliability of the equipment. Through precise mechanical limiting, the telescopic channel 32 can slide more stably, ensuring the correct response of the nebulizer in different breathing stages. This design not only extends the service life of the equipment, but also improves the patient's user experience, making it more stable and reliable in long-term use.

[0028] As a preferred embodiment, the control structure 5 includes a follower component 51 connected to the atomizing mask 2, a pressure component 53 connected to the atomizing component 4, and a connecting component 52 connecting the follower component 51 and the pressure component 53. The follower component 51 is adsorbed and moves toward the atomizing mask 2 along with the telescopic channel 32. The connecting component 52 transmits the linear motion of the follower component 51 to the rotational motion of the pressure component 53, so as to drive the pressure component 53 to compress the gas delivery channel 31.

[0029] The follower assembly 51 is connected to the atomizing mask 2 and can move with the sliding of the retractable channel 32; the pressure assembly 53 is connected to the atomizing assembly 4 and is responsible for compressing the gas supply channel 31; the connecting assembly 52 converts the linear motion of the follower assembly 51 into the rotational motion of the pressure assembly 53. This design achieves precise control of the gas supply channel 31, ensuring that the pressure is released when the patient inhales, allowing the atomized liquid medicine to be smoothly discharged; and compressing the gas supply channel 31 during exhalation, preventing the discharge of the liquid medicine. This precise control mechanism not only improves the response speed and accuracy of the nebulizer, but also enhances the stability and reliability of the system, further improving the effect of atomization treatment and the patient's user experience.

[0030] As a specific preferred embodiment, refer to Figure 5 and Figure 6 As shown in the figure, the follower assembly 51 includes a lever 511 and a spring 512 arranged on the outside of the atomizing mask 2. One end of the lever 511 is connected to the telescopic channel 32, and the other end of the lever 511 is connected to the pressure-applying assembly 53 through the connecting assembly 52. A spring 512 is arranged between the lever 511 and the atomizing mask 2. The spring 512 is located on the side of the lever 511 connected to the telescopic channel 32. The spring 512 is used for moving and resetting the lever 511.

[0031] One end of lever 511 passes through bellows 321 and is fixedly connected to the end of bellows 321. The middle portion of lever 511 is rotatably fixed to the outside of atomizing mask 2. The other free end of lever 511 is connected to pressure assembly 53 via connecting assembly 52. When one end of lever 511 swings toward one side as bellows 321 moves, the other end of lever 511 drives pressure assembly 53, via connecting assembly 52, to act on the first section of rubber hose, thereby achieving a follow-up effect. A spring 512 is provided on the side of lever 511 near bellows 321. Spring 512 is located between lever 511 and atomizing mask 2, providing elastic support for the movement of lever 511. This design not only improves the movement accuracy and stability of follow-up assembly 51, but also achieves an automatic reset function through the elastic action of spring 512.

[0032] When the patient inhales, negative pressure causes the retractable channel 32 to slide, causing the lever 511 to swing, triggering the pressure-applying assembly 53 to release pressure on the gas delivery channel 31. During exhalation, the negative pressure disappears, and the elastic action of the spring 512 resets the lever 511, allowing the pressure-applying assembly 53 to re-compress the gas delivery channel 31. This automatic reset mechanism ensures the nebulizer responds correctly during different breathing phases, reduces treatment interruptions due to mechanical failures, and further improves device reliability and patient convenience.

[0033] Example 2 Reference Figure 5 and Figure 6 As shown in FIG, based on the first embodiment, the connecting assembly 52 of this embodiment includes a bracket 521, a connecting rod 522 hingedly connected to the lever 511, and a rotating rod 523 connected to the pressure assembly 53. The two ends of the bracket 521 are respectively connected to the atomizer body 1 and the atomizing mask 2. The rotating rod 523 is hingedly connected to the adjacent ends of the connecting rod 522. When the connecting rod 522 swings with the lever 511, it can drive the rotating rod 523 and the pressure assembly 53 to rotate. The middle portion of the aforementioned lever 511 intersects and connects to the bracket 521. When the free end of the lever 511 is driven to move in the opposite direction of the movement of the bellows 321, the connecting rod 522 and the rotating rod 523 are driven to rotate, thereby converting linear motion into rotational motion. This achieves compression or decompression of the gas transmission channel 31. This design not only effectively converts the linear motion of the lever 511 into the rotational motion of the pressure assembly 53, but also ensures the accuracy and reliability of the motion through the stable support of the bracket 521. In addition, this mechanical transmission design reduces dependence on electronic components, reduces the complexity and cost of the equipment, and improves the durability and maintenance convenience of the atomizer.

[0034] In order to ensure the accuracy of the direction of rotation of the connecting rod 522 and the rotating rod 523. As an option, the connecting structure also includes a limiter for limiting the rotation of the rotating rod 523. Specifically, a limiter plate 524 is provided on the bracket 521 at one end close to the atomizing mask 2. The limiter plate 524 is located on one side of the hinged end 5231 of the connecting rod 522 and the rotating rod 523. When the connecting rod 522 drives the rotating rod 523 to rotate, the limiter plate 524 is used to limit the angular range in which the rotating rod 523 can rotate. The limiter plate 524 allows the connecting rod and the rotating rod 523 to rotate only 180 degrees at most. Thus, when the lever 511 drives the connecting rod and the rotating rod 523 to move, after the rotating rod 523 rotates 180 degrees in one direction, as the lever 511 continues to move, the rotating rod 523 can only rotate in the opposite direction, so as to effectively prevent the connecting rod and the rotating rod 523 from rotating into a full circle, affecting the normal operation of the pressure assembly 53.

[0035] It should be noted that a hinged end 5231 is provided between the end of the connecting rod 522 and the end of the rotating rod 523. This hinged end 5231 is located on one side of the end of the rotating rod 523 and has a certain tilt angle, thereby ensuring that the connecting rod 522 can smoothly transmit power to the rotating rod 523 and drive the rotating rod 523 to rotate. Specifically, when the lever 511 moves in one direction, the connecting rod 522 swings accordingly and transmits force to the rotating rod 523 through the tilted hinged end 5231, causing the rotating rod 523 to rotate 180 degrees to the left. Subsequently, when the lever 511 moves in the opposite direction, the connecting rod 522 swings again, transmitting force to the rotating rod 523 through the hinged end 5231, causing the rotating rod 523 to rotate 180 degrees to the right. Due to the presence of the limit plate 524, the rotating rod 523 will not exceed 180 degrees during the rotation process, thereby avoiding the generation of a perfect circular motion. This design not only ensures that the movement range of the rotating rod 523 is within the predetermined 180 degrees, but also improves the stability and reliability of the system, so that the nebulizer can accurately control the on-off of the gas delivery channel 31 and achieve synchronization with the patient's breathing.

[0036] In this embodiment, as preferred Figure 7 As shown, the pressure-applying assembly 53 includes a support plate 531 arranged at the end of the atomizer body 1, and a drive plate 532 rotatably arranged inside the support plate 531. The end of the rotating rod 523 passes through the support plate 531 and is connected to the drive plate 532, and drives the drive plate 532 to rotate inside the support plate 531. The support plate 531 is provided with an avoidance groove 5311 for the drive plate 532 to rotate, and a support platform 5312 that cooperates with the drive plate 532 to compress the gas delivery channel 31. The gas delivery channel 31 passes through the support plate 531 and is accommodated on the support platform 5312. The drive plate 532 is driven to rotate to compress and block the gas delivery channel 31.

[0037] This design not only enables precise control of the gas delivery channel 31, but also provides the necessary space and support for the movement of the drive disc 532 through the design of the avoidance groove 5311 and the support platform 5312, ensuring stable operation of the system. Furthermore, this design improves the nebulizer's response speed and accuracy, further enhancing the effectiveness of aerosol therapy and the patient's experience.

[0038] Working principle: When the patient inhales, negative pressure is generated in the atomizing mask 2, and this negative pressure drives the telescopic channel 32 to slide inward. As the telescopic channel 32 slides, the control structure 5 is triggered, releasing the pressure on the gas supply channel 31, making the gas supply channel 31 unobstructed. This process is completed by the follower component 51, the pressure component 53 and the connecting component 52. The follower component 51 can move as the telescopic channel 32 slides, and converts the linear motion into the rotational motion of the pressure component 53 through the connecting component 52. The pressure component 53 is responsible for compressing the gas supply channel 31 to achieve the opening and closing of the gas supply channel 31. The spring 512 in the follower component 51 provides elastic support for the movement of the lever 511 and realizes the automatic reset function, ensuring that when the patient exhales, the control structure 5 can quickly reset and block the gas supply channel 31. The limiter in the connecting component 52 ensures that the movement range of the rotating rod 523 is within the predetermined 180 degrees, preventing the circular motion from affecting the normal operation of the pressure component 53. When lever 511 drives connecting rod 522 and rotating rod 523 to move, rotating rod 523 rotates 180 degrees in one direction and then can only rotate in the opposite direction as lever 511 continues to move. This design not only ensures that the rotating rod 523's range of motion is within the predetermined 180-degree range, but also improves the stability and reliability of the system, allowing the nebulizer to precisely control the opening and closing of gas delivery channel 31, achieving synchronization with the patient's breathing.

[0039] On the contrary, when the patient exhales, the negative pressure in the mask disappears. At this time, the telescopic channel 32 is reset under the action of the spring 512 or other elastic elements, and the control structure 5 is reset and re-compresses the air delivery channel 31 to block the flow of gas.

[0040] Example 3 In this embodiment, based on the first and second embodiments, the sensing structure includes a detection sensor for detecting the movement of the drive disk 532. The detection sensor can sense the motion state of the drive disk 532 in real time and transmit a signal to the atomization assembly 4, thereby achieving precise control of the atomization process. This design not only improves the intelligence level of the nebulizer, but also ensures the accuracy and reliability of respiratory synchronization. Through precise signal transmission, the atomization assembly 4 can promptly start atomization when the patient inhales and promptly stop atomization when the patient exhales, avoiding the irritation of the respiratory tract caused by the atomized liquid during the exhalation phase of the traditional nebulizer, reducing the patient's discomfort, and improving the treatment effect and the patient's user experience. Specifically, the detection sensor can adopt an angle sensor in the prior art to detect the rotation direction and rotation angle of the drive disk 532, thereby determining whether there is a contact and compression relationship between the drive disk 532 and the gas supply channel 31, and thus determining whether the gas supply channel 31 is open or closed.

[0041] In addition, the atomization assembly 4 in this embodiment includes an electric control board 41 and an atomization sheet 42 electrically connected to the electric control board 41. The atomization sheet 42 is arranged at the outlet of the atomization nozzle of the nebulizer body 1, and the electric control board 41 is arranged inside the nebulizer body 1. This design not only realizes the atomization function, but also ensures the stability and consistency of the atomization process through the precise control of the electric control board 41. The electric control board 41 can accurately control the start and stop of the atomization sheet 42 according to the signal transmitted by the sensing structure, further improving the response speed and accuracy of the nebulizer. This design not only improves the treatment effect, but also reduces drug waste and improves the patient's user experience.

[0042] Specific examples Figure 8 As shown, the atomization assembly 4 includes: an electric control board 41 and an atomization sheet 42 electrically connected to the electric control board 41. The outlet of the atomization nozzle is provided with a through hole, and the atomization sheet 42 is arranged in the through hole. The electric control board 41 is arranged in the atomizer body 1, and the atomization sheet 42 is an ultrasonic atomization sheet 42. Among them, the electric control board 41 and the atomization sheet 42 can be electrically connected through a spring pin 43. When the electric control board 41 receives the atomization command, it controls the atomization sheet 42 to start atomization.

[0043] Working principle: The sensing structure senses the movement of the control structure 5, detects that the air supply channel 31 is in a state of being relieved of compression, and quickly sends a sensing signal to the atomizer assembly 4. After the atomizer assembly 4 receives the signal, the electric control board 41 starts the atomizer plate 42, begins to atomize the liquid medicine into tiny particles, and delivers it to the atomizer mask 2 through the air supply channel 31 for the patient to inhale. The pressure-applying assembly 53 compresses and blocks the air supply channel 31 through the rotation of the drive disk 532, thereby achieving on-off control of the air supply channel 31. The detection sensor in the sensing structure can sense the rotation direction and angle of the drive disk 532 in real time, and transmit the signal to the atomizer assembly 4, thereby achieving precise control of the atomization process. The atomizer assembly 4 accurately controls the start and stop of the atomizer plate 42 according to the signal transmitted by the sensing structure, ensuring the stability and consistency of the atomization process, and further improving the response speed and accuracy of the nebulizer.

[0044] On the contrary, when the patient exhales, the negative pressure in the mask disappears. At this time, the retractable channel 32 is reset under the action of the spring 512 or other elastic element, and the control structure 5 is reset and re-compresses the gas supply channel 31, blocking the flow of gas. The sensing structure senses the movement of the control structure 5 again, detects the compressed and blocked state of the gas supply channel 31, and sends a signal to the atomizer assembly 4. After the atomizer assembly 4 receives the signal, the electric control board 41 stops the operation of the atomizer plate 42 and stops atomizing the liquid medicine, avoiding the continued output of the liquid medicine when the patient exhales, reducing drug waste and avoiding unnecessary inhalation.

[0045] The above description is only a preferred embodiment of this embodiment and is not intended to limit this embodiment. Any modifications, equivalent replacements and improvements made within the spirit and principles of this embodiment should be included in the scope of protection of this embodiment.
