Description

Technical Field

[0001] This invention belongs to the field of medical testing equipment technology, specifically relating to a respiratory intensity monitoring device and its adapted alarm device. Background Technology

[0002] In the fields of medical diagnosis and health monitoring, accurate monitoring of patients' respiratory function is of paramount importance. Respiratory intensity, as a key indicator reflecting the functional state of the human respiratory system, provides valuable insights for early disease detection, disease assessment, and treatment planning. However, existing respiratory intensity monitoring technologies and equipment still have many limitations in practical clinical applications, making it difficult to meet the growing clinical demands.

[0003] For example, a respiratory sound monitoring device according to Chinese patent application number CN202310962307.9 includes a microphone and an external speaker. The microphone and the external speaker are wirelessly connected. During use, the microphone is attached to the surface of the human skin. During human breathing, the microphone detects the respiratory sounds produced by human breathing and converts the respiratory sounds into electrical signals. After the microphone converts the respiratory sounds into electrical signals, it sends the electrical signals to the external speaker. The external speaker converts the electrical signals back into respiratory sounds and broadcasts them through a broadcasting device. During the process of the external speaker converting the electrical signals back into respiratory sounds, the external speaker amplifies the electrical signals through an amplification circuit, so that the reconverted respiratory sounds can be heard by medical staff, and the respiratory sounds heard by medical staff are more natural.

[0004] Monitoring devices of the above types can only provide a single data output when in use, lacking an intuitive visual feedback mechanism, which is not conducive to medical staff quickly judging the respiratory status. More critically, existing respiratory monitoring systems lack a tiered early warning mechanism. In monitoring scenarios, if a patient shows signs of respiratory failure and an alert is not issued in time, it may lead to missing the golden window for treatment. Summary of the Invention

[0005] The purpose of this invention is to provide a respiratory intensity monitoring device and its compatible alarm device, which can realize visual monitoring of respiratory intensity, graded early warning and personalized adjustment.

[0006] The specific technical solution adopted by this invention is as follows: A respiratory intensity monitoring device, including a breathing mask; An air intake hood is fixedly connected to the inclined surface of the breathing mask; An exhaust pipe is fixedly connected to the side of the breathing mask; A measuring mechanism, which is also fixedly connected to the side of the breathing mask; The monitoring mechanism includes a flipping part disposed on the air outlet pipe and an adjustment part disposed on the flipping part; Connecting ear, which is fixedly connected to the breathing mask; Air is inhaled through the intake hood and exhaled through the exhaust pipe; the exhaled air causes the flipping part to rotate, and the rotation of the flipping part causes the components on the measuring mechanism to move, and the exhalation amplitude is monitored based on the amount of displacement.

[0007] In a preferred embodiment, a first duckbill valve is installed at one end of the air intake hood near the breathing mask, and a filter screen is provided at the other end of the air intake hood to block dust in the air.

[0008] In a preferred embodiment, a second duckbill valve is installed at the end of the air outlet tube near the breathing mask.

[0009] In a preferred embodiment, the measuring mechanism includes a vertical rod, a sliding rod fixedly connected to the vertical rod, the sliding rod being hexagonal prism-shaped, and a stop block provided at the end away from the vertical rod. A slider is slidably connected to the sliding rod, and a U-shaped rod is fixedly connected to the slider.

[0010] In a preferred embodiment, the flipping part includes mounting blocks, two mounting blocks are fixedly connected to the air outlet pipe, and rotating rods are rotatably connected to the two mounting blocks via bearings. A sealing plate is fixedly connected to the rotating rods. A flow guide seat is fixedly connected to the inner wall of the air outlet pipe, and one end of the flow guide seat is in contact with the sealing plate. Fixing blocks are fixedly sleeved on both ends of the rotating rods. An n-shaped rod is fixedly connected to the two fixing blocks. A round rod is fixedly connected to the n-shaped rod. An elliptical ring is fixedly connected to the round rod, and the elliptical ring is sleeved on the outside of the U-shaped rod.

[0011] In a preferred embodiment, the adjusting part includes a collar rotatably connected to the mounting block. Locking grooves are provided in a ring-shaped arrangement on the outer ring of the mounting block, inside the collar. A torsion spring is fixedly connected to the side of the collar, and the other end of the torsion spring is fixedly connected to the fixing block. A locking rod is slidably inserted into the collar. A retaining ring is fixedly sleeved on one end of the locking rod. A tension spring is fixedly connected to one side of the retaining ring, and the other end of the tension spring is fixedly connected to the collar.

[0012] An alarm device adapted to a respiratory intensity monitoring device, suitable for any of the above-mentioned respiratory intensity monitoring devices, comprising: An alarm mechanism is provided, comprising an air inflator mounted on a measuring mechanism and an air deflation part mounted on the air inflator. The breathing mask is also provided with an alarm part.

[0013] In a preferred embodiment, the air inflator includes a first hollow cylinder, which is fixedly connected to a slide rod. A piston rod is piston-type inserted into one end of the first hollow cylinder. A piston plate is fixedly connected to one end of the piston rod inside the first hollow cylinder, and the other end of the piston rod is fixedly connected to a slider. A second hollow cylinder is fixedly connected to one end of the first hollow cylinder, and an air bladder is fixedly installed at the other end of the second hollow cylinder. A first one-way valve is installed at the end of the second hollow cylinder near the first hollow cylinder, and an air inlet pipe is fixedly connected to the end of the first hollow cylinder near the second hollow cylinder. A second one-way valve is installed on the air inlet pipe.

[0014] In a preferred embodiment, the venting section includes an L-shaped hollow rod, which is fixedly connected to the piston rod. An L-shaped tube is fixedly connected to the second hollow cylinder, and a third duckbill valve is fixedly installed inside the L-shaped tube.

[0015] In a preferred embodiment, the alarm unit includes a contact switch mounted on a slide rod and located at the airbag, and an alarm is mounted on the breathing mask.

[0016] The technical effects achieved by this invention are as follows: This invention enables real-time, visualized monitoring of respiratory intensity, significantly improving the efficiency of clinical assessment. By using a slider with graduated lines and red, yellow, and green color zones, along with a movable block, the patient's expiratory intensity can be directly converted into the slider's position on the slider. A green area represents normal breathing, a yellow area indicates weakened breathing, and a red area warns of rapid breathing. Caregivers do not need to rely on specialized equipment; they can quickly assess the patient's respiratory status simply by observing the intuitive color zones, greatly improving the convenience and response speed of monitoring. This is particularly suitable for emergency situations, transport, and other medical scenarios requiring rapid decision-making. This invention effectively prevents the risk of respiratory function deterioration by introducing a mechanical graded early warning and automatic alarm mechanism. When a patient repeatedly expels insufficient air (the slider remains in the yellow area) and fails to trigger the decompression action in the green area, the airbag will gradually inflate due to continuous pressurization, eventually touching the contact switch and activating the alarm. This mechanical linkage structure requires no external power to drive the sensing and judgment, ensuring high reliability and avoiding misjudgment or delays in the electronic system. It ensures timely audible and visual alarms in the early stages of respiratory failure and can remotely notify medical staff via the Internet of Things, gaining valuable time for treatment. This invention offers excellent personalization and wearing comfort. Through the torsion spring preload design in the adjustment section, the sensitivity of the flipping section can be flexibly adjusted according to the breathing intensity of different patients (such as children, the elderly, or frail patients), ensuring monitoring accuracy. Simultaneously, the device integrates a duckbill valve and filter to ensure unidirectional airflow and air cleanliness, improving safety and comfort. The overall structure is lightweight, and with the connecting ear and fixing strap, it is easy to wear stably, suitable for long-term monitoring scenarios, and has good clinical application value.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0022] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0023] Please see the appendix Figures 1 to 3 As shown, this is the first embodiment of the present invention, which provides a breathing intensity monitoring device, including a breathing mask 1; Air intake hood 2 is fixedly connected to the inclined surface of breathing mask 1; The air outlet tube 3 is fixedly connected to the side of the breathing mask 1. Measuring mechanism 4 is also fixedly connected to the side of breathing mask 1; The monitoring mechanism 5 includes a flipping part 51 disposed on the air outlet pipe 3 and an adjustment part 52 disposed on the flipping part 51; Connecting ear 7 is fixedly connected to breathing mask 1; Air is inhaled through the air intake hood 2 and exhaled through the air outlet 3; the exhaled air causes the flipping part 51 to rotate, and the rotation of the flipping part 51 causes the components on the measuring mechanism 4 to move, and the exhalation amplitude is monitored based on the amount of displacement.

[0024] In this embodiment, the design of the air intake hood 2 allows air to enter the breathing mask 1 smoothly, while the air outlet 3 ensures that the exhaled air can be discharged smoothly, avoiding accumulation in the breathing mask 1 and causing discomfort.

[0025] The measuring mechanism 4 is used to detect the rotation of the flipping part 51 and convert it into linear displacement. In this way, the breathing intensity can be monitored based on the force of exhaled gas, providing important information for medical diagnosis.

[0026] The flipping part 51 of the monitoring device 5 is connected to the exhaust pipe 3. When exhaled air passes through the exhaust pipe 3, the airflow will push the flipping part 51 to rotate. The adjustment part 52 is used to adjust the sensitivity of the flipping part 51 to adapt to the breathing habits and needs of different patients.

[0027] The connection to ear 7 facilitates the connection of the respiratory intensity monitoring device to the fixation strap or other wearing devices, allowing the entire device to be worn stably on the patient's head or face, ensuring the accuracy of the monitoring results.

[0028] Secondly, please refer to it again. Figure 2 The intake hood 2 is equipped with a first duckbill valve 21 at one end near the breathing mask 1, and a filter 22 is provided at the other end of the intake hood 2 to block dust in the air; the exhaust pipe 3 is equipped with a second duckbill valve 31 at one end near the breathing mask 1.

[0029] In this embodiment, both the first duckbill valve 21 and the second duckbill valve 31 are designed as one-way valves, ensuring that air can only flow in one direction. The first duckbill valve 21 allows outside air to smoothly enter the breathing mask 1, providing the patient with fresh breathing air while preventing exhaled air from flowing back. The filter 22 further improves the quality of the breathing air by blocking dust and fine particulate matter in the air, protecting the patient's respiratory system from external pollutants.

[0030] In addition, the second duckbill valve 31 on the exhaust tube 3 also serves as a one-way valve, ensuring that exhaled air can be smoothly discharged and avoiding accumulation in the breathing mask 1, which could cause breathing difficulties or discomfort. This design not only improves the accuracy of respiratory intensity monitoring but also provides patients with a safer and more comfortable breathing environment.

[0031] Secondly, please refer to it again. Figure 1 , Figure 8 and Figure 10The measuring mechanism 4 includes a vertical rod 41, a sliding rod 42 fixedly connected to the vertical rod 41, and the sliding rod 42 is hexagonal prism-shaped. A stop is provided at one end away from the vertical rod 41 to limit the initial position of the slider 43. The slider 43 is slidably connected to the sliding rod 42, and a U-shaped rod 44 is fixedly connected to the slider 43.

[0032] Please refer to it again. Figures 3 to 7 The flipping part 51 includes mounting blocks 511. Two mounting blocks 511 are fixedly connected to the air outlet pipe 3. A rotating rod 512 is rotatably connected to the two mounting blocks 511 via bearings. A sealing plate 513 is fixedly connected to the rotating rod 512. A guide seat 514 is fixedly connected to the inner wall of the air outlet pipe 3, and one end of the guide seat 514 is in contact with the sealing plate 513. Fixing blocks 515 are fixedly sleeved at both ends of the rotating rod 512. An n-shaped rod 516 is fixedly connected to the two fixing blocks 515. A round rod 517 is fixedly connected to the n-shaped rod 516. An elliptical ring 518 is fixedly connected to the round rod 517, and the elliptical ring 518 is sleeved on the outside of the U-shaped rod 44.

[0033] In this embodiment, when gas is discharged along the outlet pipe 3, it flows through the guide seat 514. The inner diameter of the guide seat 514 is designed to gradually decrease, which effectively accelerates the airflow speed. As the airflow accelerates, the impact on the sealing plate 513 increases, causing it to respond quickly. The exhaled gas has a certain force, which pushes the sealing plate 513 to flip. The flipping action of the sealing plate 513 further drives the rotation of the rotating rod 512. The rotation of the rotating rod 512, in turn, causes the n-shaped rod 516 on the fixed block 515 to flip. The flipping action of the n-shaped rod 516 is further transmitted to the round rod 517 and the elliptical ring 518, causing them to also flip. The flipping action of the elliptical ring 518 causes the slider 43 on the U-shaped rod 44 to move along the slide rod 42. By monitoring the displacement of the slider 43, the intensity of the exhalation can be indirectly understood. In addition, the lever principle can be used to amplify the displacement of slider 43, so that caregivers can see the displacement change of slider 43 more intuitively and thus more accurately assess the exhalation intensity.

[0034] A scale is set on the slider 42. These scales not only accurately indicate the values, but also divide the area into three different color zones for easy observation and judgment. The three colors are arranged from left to right: red, green, and yellow (e.g., ...). Figure 10 (As shown). This design allows for a quick and intuitive assessment of the patient's respiratory status during actual use.

[0035] Specifically, when the patient exhales, the flipping part 51 converts the rotational motion into linear displacement of the U-shaped rod 44 via the elliptical ring 518, driving the slider 43 on the graduated slide rod 42 to move. If the slider 43 smoothly stops in the green area during exhalation, it indicates that the patient's breathing is normal and there are no abnormalities. The presence of the green area provides caregivers with a clear reference standard, ensuring they can quickly determine whether the patient's breathing is healthy.

[0036] Conversely, if slider 43 slides into the red zone during exhalation, it indicates that the patient is experiencing shortness of breath. The red zone is designed to alert caregivers, prompting them to immediately monitor the patient's breathing and take appropriate measures to alleviate discomfort.

[0037] Finally, when slider 43 only reaches the yellow area during exhalation, it indicates that the patient's respiratory function has weakened. The presence of the yellow area provides a warning signal to caregivers, suggesting that the patient may be experiencing respiratory failure and requires further examination and treatment.

[0038] With this slider 42 design featuring graduated lines and three-color zones, caregivers can more conveniently and accurately monitor and assess the patient's respiratory status, thereby providing timely and effective medical care.

[0039] Please refer to it again. Figures 5 to 7 The adjusting part 52 includes a collar 521, which is rotatably connected to the mounting block 511. Locking grooves 522 are provided in a ring-shaped pattern on the outer ring of the mounting block 511 and inside the collar 521. A torsion spring 523 is fixedly connected to the side of the collar 521, and the other end of the torsion spring 523 is fixedly connected to the fixing block 515. A locking rod 524 is slidably inserted into the collar 521. A retaining ring 525 is fixedly sleeved on one end of the locking rod 524. A tension spring 526 is fixedly connected to one side of the retaining ring 525, and the other end of the tension spring 526 is fixedly connected to the collar 521.

[0040] In this embodiment, as the rotating rod 512 rotates, it drives the fixed block 515 connected to it to rotate synchronously. At the same time, the rotating rod 512 also applies torque to the torsion spring 523 between the fixed block 515 and the collar 521, causing it to twist. When the patient completes the exhalation, the torsion spring 523, under its own restoring force, returns all components to their initial positions.

[0041] In addition, the preload of the torsion spring 523 can be adjusted to suit different patients' specific conditions. By adjusting the preload of the torsion spring 523, the force required for the sealing plate 513 to flip can be changed. If the patient's breathing intensity is low, the preload of the torsion spring 523 can be appropriately reduced, so that the patient only needs to exhale less air to push the sealing plate 513 to flip. Conversely, if the patient's breathing intensity is high, the preload of the torsion spring 523 can be appropriately increased, so that the patient needs to exhale more air to push the sealing plate 513 to flip. In this way, the force required for the sealing plate 513 to flip can be adjusted according to the patient's specific condition, thereby ensuring that the slider 43 can slide normally. This ensures that when the patient is breathing normally, the slider 43 can move smoothly to the green area, facilitating effective monitoring and analysis of the patient's breathing intensity.

[0042] Specifically: Pull the locking rod 524 out of the locking groove 522, simultaneously stretching the tension spring 526. After the locking rod 524 disengages from the locking groove 522, the collar 521 can be rotated. Rotating the collar 521 twists the torsion spring 523, thereby adjusting the preload of the torsion spring 523. After adjustment, release the locking rod 524. The locking rod 524 returns to its original position under the rebound force of the tension spring 526 and inserts into the corresponding locking groove 522 to fix the collar 521.

[0043] Example 2 Please refer to it again. Figure 1 , Figure 8 , Figure 9 and Figure 10 This is a second embodiment of the present invention, which provides an alarm device adapted to a respiratory intensity monitoring device, applicable to any of the above-mentioned respiratory intensity monitoring devices, comprising: The alarm mechanism 6 includes an air inflator 61 installed on the measuring mechanism 4 and an air deflation part 62 installed on the air inflator 61. The breathing mask 1 is also equipped with an alarm part 63.

[0044] Please refer to it again. Figure 8 and Figure 9The air inflator 61 includes a first hollow cylinder 611, which is fixedly connected to a slide rod 42. A piston rod 612 is piston-type inserted into one end of the first hollow cylinder 611. A piston plate 613 is fixedly connected to one end of the piston rod 612 inside the first hollow cylinder 611, and the other end of the piston rod 612 is fixedly connected to a slider 43. A second hollow cylinder 614 is fixedly connected to one end of the first hollow cylinder 611. An air bag 615 is fixedly installed at the other end of the second hollow cylinder 614. A first one-way valve 616 is installed at the end of the second hollow cylinder 614 near the first hollow cylinder 611. An air inlet pipe 617 is fixedly connected to the end of the first hollow cylinder 611 near the second hollow cylinder 614. A second one-way valve 618 is installed on the air inlet pipe 617.

[0045] It should be noted that: the function of the first one-way valve 616 is to allow gas to enter the second hollow cylinder 614 from the first hollow cylinder 611, and not to allow gas to flow back to the first hollow cylinder 611 along the second hollow cylinder 614; the function of the second one-way valve 618 is to allow gas to enter the first hollow cylinder 611 along the air inlet pipe 617, and not to allow gas in the first hollow cylinder 611 to be discharged along the air inlet pipe 617.

[0046] Please refer to it again. Figure 8 and Figure 9 The venting part 62 includes an L-shaped hollow rod 621, which is fixedly connected to the piston rod 612. An L-shaped tube 622 is fixedly connected to the second hollow cylinder 614, and a third duckbill valve 623 is fixedly installed inside the L-shaped tube 622.

[0047] In this embodiment, a through groove is provided on the L-shaped hollow rod 621 to ensure that the gas entering the L-shaped hollow rod 621 can be discharged in a timely manner.

[0048] Please refer to it again. Figure 1 , Figure 8 and Figure 10 The alarm unit 63 includes a contact switch 631, which is mounted on the slide bar 42 and located at the airbag 615. An alarm 632 is mounted on the breathing mask 1.

[0049] In this embodiment, when the slider 43 moves, it pulls the piston rod 612 to move accordingly. The movement of the piston rod 612 further drives the piston plate 613 to move along the interior of the first hollow cylinder 611. During this process, the piston plate 613 pushes the air inside the first hollow cylinder 611 towards the second hollow cylinder 614. Through this mechanical movement, the air pressure inside the second hollow cylinder 614 can be effectively increased. As the air pressure increases, the air bladder 615 connected to the second hollow cylinder 614 will expand accordingly, thereby achieving the desired mechanical effect.

[0050] At the same time, when the slider 43 completes its pushing task and drives the piston plate 613 back to the initial position, outside air will be drawn into the first hollow cylinder 611 through the air intake pipe 617 to replenish the amount of air consumed by pushing the airbag 615 to expand.

[0051] Furthermore, as the slider 43 continues to move, when it enters a specific green area, the L-shaped hollow rod 621 will come into contact with the third duckbill valve 623. In this contact state, the L-shaped hollow rod 621 will pass through the third duckbill valve 623. Since the L-shaped tube 622 is connected to the second hollow cylinder 614, the air pressure inside them is the same. In this situation, air inside the second hollow cylinder 614 will enter the L-shaped hollow rod 621 and be discharged to the atmosphere through a pre-drilled slot on the L-shaped hollow rod 621, thereby achieving the purpose of pressure relief.

[0052] Specifically, when slider 43 slides within the yellow area, it pressurizes the second hollow cylinder 614, causing the airbag 615 to inflate. When slider 43 slides to the green area, the L-shaped hollow rod 621 is inserted into the L-shaped tube 622 from the third duckbill valve 623, depressurizing the second hollow cylinder 614, after which the airbag 615 contracts.

[0053] If slider 43 slides only within the yellow area several times to pressurize the second hollow cylinder 614, but fails to slide into the green area to depressurize it, the air pressure inside the second hollow cylinder 614 will continue to rise, causing the airbag 615 to inflate more rapidly. After several consecutive pressurizations, the airbag 615 will inflate to a specific degree, triggering the contact switch 631. Contact switch 631 is electrically connected to alarm 632. Once the inflation of the airbag 615 exceeds a preset value, i.e., triggers contact switch 631, alarm 632 will immediately activate, sending an alarm signal to alert caregivers that the patient's breathing has decreased and appropriate nursing care needs to be initiated immediately.

[0054] Alarm 632 is equipped with a rechargeable battery and uses a commercially available product. When selecting a model, it should, as far as possible, meet the requirements of this application, provided that the specifications and usage scenarios are suitable. Specific model specifications are not limited here. Preferably, alarm 632 has audio alarm and flashing light functions, and should also have built-in WIFI, Bluetooth, IoT and other remote information transmission functions to send information to remind medical staff.

[0055] It should be noted that the upper components of monitoring mechanism 5 and alarm mechanism 6, especially those that need to move or operate, should be manufactured using lightweight materials (such as medical-grade polymers). This is to reduce the overall weight of the equipment, improving its flexibility and response speed. Lightweight materials not only reduce mechanical wear and extend the service life of components, but also reduce energy consumption to some extent and improve system operating efficiency. Furthermore, using lightweight materials can reduce potential safety hazards caused by excessive component weight, ensuring the stability and reliability of the monitoring and alarm system.

[0056] The working principle of this invention is as follows: When a patient breathes while wearing a breathing mask 1 containing an intake mask 2 and an exhaust tube 3, the exhaled air impacts the flipping part 51 of the monitoring mechanism 5 through the exhaust tube 3. The airflow accelerated by the guide seat 514 pushes the sealing plate 513, which in turn drives the rotating rod 512, the fixing block 515, the n-shaped rod 516, and the elliptical ring 518 to move in tandem. This causes the slider 43 on the U-shaped rod 44 to move linearly along the hexagonal prism-shaped slide rod 42. This displacement is amplified by the lever principle and the breathing intensity is visually displayed through the red / green / yellow three-color scale area set on the surface of the slide rod 42—green indicates normal breathing, red indicates rapid breathing, and yellow indicates weakened breathing. The measuring mechanism 4 precisely controls the rotation of the flipping part 51 through the upright rod 41 and the slide rod 42 assembly. The displacement is converted into a quantifiable linear displacement. At the same time, the movement of slider 43 drives the piston rod 612 connected to it to reciprocate in the air inflator 61, realizing the periodic pressurization and depressurization of the airbag 615. When slider 43 enters the green area, the L-shaped hollow rod 621 is inserted into the L-shaped tube 622 and the depressurization channel is opened, and the airbag 615 deflates and contracts. If slider 43 stays in the yellow area and cannot trigger depressurization, the air pressure in the airbag 615 accumulates and expands. When the threshold is reached, the contact switch 631 is triggered, and the alarm 632 is activated to emit sound and light and remote alarms, realizing automatic monitoring and early warning of respiratory function abnormalities. The preload of torsion spring 523 can be changed through the adjustment part 52 to adapt to the respiratory sensitivity needs of different patients.
