[0002] As medical technology continues to innovate, the performance optimization of nebulizer inhalation equipment, as a key device to ensure the smooth implementation of surgery and related treatments, has always been a research focus in the medical field.

[0003] At present, bronchospasm may occur during surgery, especially for patients under general anesthesia. At this time, most of our anesthesiologists use intravenous drugs or directly administer drugs through endotracheal tubes, which are relatively ineffective. The drug can be atomized and then connected to the endotracheal tube, which will not affect ventilation and can better deliver the drug to the lungs to achieve a better effect of bronchial dilation.

[0004] For another example, for critically ill patients who are intubated and receiving ventilator-assisted ventilation, the drugs can be nebulized and then connected to the endotracheal tube, which can continuously deliver expectorants and bronchial dilating drugs. This does not affect the patient's ventilation, avoids many risks of hypoxemia and hypercapnia, and maximizes the effect of the drugs.

[0005] In view of this, this application is hereby filed. Summary of the invention

[0006] The purpose of the present invention is to provide an atomization inhalation device during anesthesia to solve the problems raised in the above background technology.

[0007] To solve the above technical problems, the present invention provides an atomization inhalation device for anesthesia, comprising an atomizer, wherein the atomizer is connected to an inhalation tube, a control chamber is arranged between the atomizer and the inhalation tube, a wind wheel is rotatably connected in the control chamber, a linear switch is arranged on the bottom surface of the wind wheel, the linear switch is electrically connected to the atomizer, the other end of the linear switch is slidably connected to a movable pull rod, the bottom surface of the wind wheel is connected to a sliding sleeve, a sliding block is slidably connected in the sliding sleeve, the sliding block is fixedly connected to the movable pull rod, and a spring is arranged between the sliding block and the sliding sleeve.

[0008] Furthermore, a mounting plate is provided in the control cavity, a rotating shaft is installed in the mounting plate, a connecting shaft is provided on the bottom surface of the wind wheel, and the connecting shaft is fixedly connected to the rotating shaft.

[0009] Furthermore, the bottom surface of the connecting shaft is connected to a mounting block, a mounting cavity is defined in the mounting block, the linear switch is disposed in the mounting cavity, the sliding sleeve is fixedly connected to the mounting block, and a sealing gasket is disposed on the contact surface between the mounting cavity and the sliding sleeve.

[0010] Furthermore, a guide ring is provided in the control cavity, and the guide ring is funnel-shaped. The side of the wind wheel is provided with forward-swept blades, and the forward-swept blades are adapted to the shortest inner diameter of the guide ring.

[0011] Furthermore, the sliding sleeve is made of magnetic material, the spring is connected to a magnetic ring, and the magnetic ring and the sliding sleeve have the same magnetic pole.

[0012] Furthermore, the other end of the suction pipe is connected to a suction port, the suction port is made of flexible material, one end of a plurality of elastic diaphragms is arranged in the suction port, the elastic diaphragms are arranged in an array, and the other end of the elastic diaphragms is inclined toward the suction pipe.

[0013] Furthermore, a hollow groove is provided in the wind wheel.

[0014] Furthermore, a display screen is provided on the top surface of the atomizer, a storage hoop adapted to the inlet is provided on the front surface of the atomizer, and a control panel is provided on the top surface of the atomizer.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, a wind wheel is used to sense the patient's respiratory airflow. The wind wheel directly interacts with the respiratory airflow and senses the airflow changes in a purely mechanical way. It is not affected by any electromagnetic interference. No matter what complex electromagnetic environment it is in, it can accurately and stably sense the patient's respiratory state, providing a reliable basis for the equipment to accurately adjust the working parameters, ensuring that the use process is safe and effective.

[0017] In the present invention, the device automatically adjusts the inlet aperture according to the patient's respiratory frequency and tidal volume through an elastic diaphragm, thereby changing the size of the atomized particles. When the respiratory frequency is fast and the tidal volume is large, smaller atomized particles are generated, which penetrate deep into the respiratory tract with the help of rapid airflow, increase the contact area between the drug and the mucosa, and promote drug absorption; when the respiratory frequency is slow and the tidal volume is small, larger particles are generated to adapt to the slow airflow, ensuring that the drug is effectively deposited on the surface of the respiratory tract, so that the drug can accurately act on each bronchi under various respiratory conditions, effectively ensuring the contact between the drug and the bronchi, and greatly improving the treatment effect.

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0038] See also Figure 1-9 , the present invention provides a technical solution:

[0039] A nebulizer inhalation device for anesthesia, comprising a nebulizer 1, a display screen 11 is arranged on the top surface of the nebulizer 1, a control panel 13 is arranged on the top surface of the nebulizer 1, and the nebulizer 1 is connected to an inhalation tube 14.

[0040] Medical staff accurately measures an appropriate amount of medicine according to the patient's specific conditions, such as age, weight, condition and regimen, and injects it into a special medicine cup or medicine storage cavity inside the nebulizer 1.

[0041] The operating medical staff can set parameters of the device through the control panel 13. The control panel 13 is integrated with a circuit control module that can convert operating instructions into electrical signals.

[0042] The key parameters that can be set include the nebulization time. For example, for patients with mild symptoms of sudden bronchospasm, a shorter nebulization time can be set, while for more complex respiratory diseases, a longer time needs to be set.

[0043] There is an airflow generating component inside the atomizer 1, which is a small air pump that generates airflow by mechanically operating compressed air; the airflow is transmitted through a pipeline and adjusted by a regulating device, and enters the atomization chamber at a constant flow rate and pressure that meets the set parameters.

[0044] In the atomization chamber, the atomizer 1 uses ultrasonic atomization technology. The high-frequency ultrasonic waves generated by the ultrasonic generator can make the molecules in the drug solution vibrate violently and break into small droplets.

[0045] The generated drug droplets are transported from the atomization chamber to the patient end through the suction tube 14. The suction tube 14 is usually made of a soft, non-toxic and airtight material to ensure that the droplets can be delivered to the patient smoothly and without leakage.

[0046] The patient breathes through a mask or endotracheal tube connected to the end of the inhalation tube 14. During the inhalation process, droplets containing the drug enter the patient's respiratory tract with the airflow. As the breathing deepens, the drug droplets are deposited in the bronchi at all levels, thereby exerting the effect.

[0047] During the above process, the display screen 11 displays the working status of the equipment in real time, such as the countdown of the set nebulization time, which is convenient for medical staff and patients to understand the nebulization process; it can present the actual output drug dosage in real time, which is convenient for medical staff to confirm whether the expected drug dosage is reached; it can also display key parameters such as the current air flow speed to ensure that the equipment operating parameters are normal.

[0048] The data of the display screen 11 are derived from various sensing devices inside the device. For example, a flow sensor monitors the air flow velocity and transmits the data to the control unit, which is displayed on the display screen 11 after processing; a pressure sensor is used to measure the pressure change in the medicine cup or the medicine storage cavity, or a weighing sensor is used to monitor the weight change of the medicine, so as to calculate the output drug dosage and display it.

[0049] In addition, if the device detects an abnormal situation, such as drug blockage, abnormal airflow, etc., an alarm will be issued through the display screen 11 to remind medical staff to deal with it in time.

[0050] A control chamber 2 is provided between the atomizer 1 and the suction pipe 14, a mounting plate 21 is provided in the control chamber 2, a rotating shaft 4 is installed in the mounting plate 21, a connecting shaft 23 is provided on the bottom surface of the wind wheel 22, and the connecting shaft 23 is fixedly connected to the rotating shaft 4;

[0051] A linear switch 26 is provided on the bottom surface of the wind wheel 22, and the linear switch 26 is electrically connected to the atomizer 1. The other end of the linear switch 26 is slidably connected to a movable pull rod 27. The bottom surface of the wind wheel 22 is connected to a sliding sleeve 3, and a sliding block 31 is slidably connected in the sliding sleeve 3. The sliding block 31 is fixedly connected to the movable pull rod 27, and a spring 32 is provided between the sliding block 31 and the sliding sleeve 3.

[0052] The bottom surface of the connecting shaft 23 is connected with a mounting block 24, a mounting cavity 25 is provided in the mounting block 24, a linear switch 26 is arranged in the mounting cavity 25, the sliding sleeve 3 is fixedly connected to the mounting block 24, and a sealing gasket is arranged on the contact surface between the mounting cavity 25 and the sliding sleeve 3;

[0053] The bottom surface of the connecting shaft 23 is connected to a mounting block 24 , in which a mounting cavity 25 is provided. A linear switch 26 is arranged in the mounting cavity 25 . The sliding sleeve 3 is fixedly connected to the mounting block 24 . A sealing gasket is arranged on the contact surface between the mounting cavity 25 and the sliding sleeve 3 .

[0054] When the patient breathes through the inhalation tube 14 , the exhaled or inhaled airflow enters the control chamber 2 , and the airflow impacts the wind wheel 22 , causing it to rotate around the rotation axis 4 .

[0055] The wind wheel 22 is fixed to the rotating shaft 4 via the connecting shaft 23, thereby ensuring stable transmission.

[0056] As the wind wheel 22 rotates, its rotation speed will change according to the strength of the patient's breathing airflow.

[0057] In the sliding sleeve 3 connected to the bottom surface of the wind wheel 22, the sliding block 31 will slide radially in the sliding sleeve 3 under the action of centrifugal force.

[0058] When the wind wheel 22 rotates at a faster speed, the centrifugal force causes the sliding block 31 to overcome the elastic force of the spring 32 and slide outward, thereby driving the movable pull rod 27 fixedly connected thereto to move.

[0059] The movable pull rod 27 further triggers the linear switch 26 to act, and the linear switch 26 converts the mechanical action into an electrical signal and transmits it to the atomizer 1 .

[0060] The linear switch 26 is arranged in the mounting cavity 25 of the mounting block 24 , and a sealing gasket is provided between the contact surface between the mounting cavity 25 and the sliding sleeve 3 to prevent foreign matter from entering and affecting the normal operation of the linear switch 26 .

[0061] After receiving the electrical signal from the linear switch 26, the atomizer 1 adjusts its own working parameters according to the preset program and algorithm.

[0062] For example, if the faster rotation speed of the impeller 22 means that the patient's breathing rate is faster, the nebulizer 1 may increase the atomized amount of the drug or adjust the airflow speed accordingly to meet the patient's changing demand for the inhaled amount of anesthetic drugs;

[0063] On the contrary, if the rotation speed of the wind wheel 22 slows down, the nebulizer 1 may reduce the drug output or adjust the airflow parameters to match the drug delivery with the patient's breathing state.

[0064] By sensing the patient's respiratory airflow through the wind wheel 22, the atomizing inhalation device can automatically adjust the working parameters according to the patient's real-time respiratory status.

[0065] When the patient's breathing rate is faster, it means that he needs more medicine per unit time. At this time, the speed of the wind wheel 22 is accelerated, and the centrifugal force slider pushes the speed change gear set to switch to a high-speed transmission ratio, the fan speed increases, and the air flow speed is improved.

[0066] This will enable more aerosolized drugs to be delivered to the patient's respiratory tract in a short period of time, ensuring that the amount of drug inhaled matches the patient's breathing needs, improving drug inhalation efficiency, and ensuring effectiveness.

[0067] When the patient's breathing rate is slow, if a high airflow rate is still maintained, the drug may pass through the respiratory tract quickly and fail to be fully deposited in the effective area.

[0068] This structure will reduce the speed of the wind wheel 22, switch the gear set to a low-speed transmission ratio, reduce the fan speed, and slow down the airflow speed, so that the drug has more time to deposit in the respiratory tract, ensuring that the drug can be effectively delivered to the target site.

[0069] By adopting the above design, patient comfort is enhanced and respiratory irritation is reduced. During anesthesia, if the air flow speed is always maintained at a high level, the high-speed air flow may have a strong impact on the patient's respiratory mucosa, causing discomfort to the patient, such as coughing, choking, etc.

[0070] By automatically adjusting the airflow speed according to the patient's breathing rate and reducing the airflow speed when the breathing rate is slow, irritation to the respiratory tract can be reduced, making the patient feel more comfortable when using the nebulizer inhalation device.

[0071] Moreover, the breathing capacity varies among different patients. For example, children, the elderly, and patients with respiratory diseases have relatively weaker breathing capacity.

[0072] This structure can automatically adapt to the breathing conditions of different patients and provide appropriate airflow speeds for each type of patient so that they can all receive nebulizer inhalation treatment smoothly.

[0073] Improve the stability of drug effects. A stable airflow speed that matches the patient's breathing state helps to accurately control the dosage of drugs delivered to the patient. When the airflow speed can be reasonably adjusted according to the breathing frequency, the drug delivery amount is more stable and accurate, avoiding excessive or insufficient drug dosage due to improper airflow speed, thereby ensuring the stability of drug effects.

[0074] During the entire process, relatively stable drug delivery needs to be maintained. Appropriate airflow velocity can enable the drug to enter the patient's body evenly and stably, which helps maintain a stable drug concentration and improve drug efficacy.

[0075] The wind wheel 22 is used to sense the patient's respiratory airflow. The wind wheel 22 directly interacts with the respiratory airflow and senses the airflow changes in a purely mechanical way. It is not affected by any electromagnetic interference. No matter what complex electromagnetic scene it is in, it can accurately and stably sense the patient's respiratory state, providing a reliable basis for the equipment to accurately adjust the working parameters, ensuring that the anesthesia process is safe and effective.

[0076] The mechanical sensing structure of the device is mainly composed of simple and solid components such as a wind wheel 22, a connecting shaft 23, a sliding sleeve 3, and a linear switch 26.

[0077] The wind wheel 22, the connecting shaft 23 and other components are made of durable materials and have good mechanical strength and stability.

[0078] The linear switch 26 is disposed in the mounting cavity 25 and isolated from the outside by a sealing gasket, thereby effectively preventing impurities from entering and affecting its normal operation.

[0079] The entire mechanical structure is simple and reliable, with loose requirements on environmental conditions and no need for complicated calibration procedures. It greatly reduces the maintenance cost and failure rate of the equipment, significantly improves the reliability and service life of the equipment, and provides strong guarantee for the long-term and stable use of the hospital.

[0080] A guide ring 5 is provided in the control cavity 2 , and the guide ring 5 is funnel-shaped. A forward-swept blade 8 is provided on the side of the wind wheel 22 , and the forward-swept blade 8 is adapted to the shortest inner diameter of the guide ring 5 . A hollow groove 6 is opened in the wind wheel 22 .

[0081] After the airflow generated by the patient's breathing enters the control cavity 2, the guide ring 5 plays an important role.

[0082] Since the guide ring 5 is funnel-shaped, when the airflow passes through, the funnel-shaped structure will guide the airflow to gradually shrink and concentrate.

[0083] According to the principles of fluid mechanics, when air flows through a contracted channel, the flow velocity increases and the pressure decreases.

[0084] This enables the airflow to flow toward the wind wheel 22 more efficiently, providing stronger power for the rotation of the wind wheel 22 .

[0085] The forward-swept blades 8 on the side of the wind wheel 22 are adapted to the shortest inner diameter of the guide ring 5 .

[0086] When the airflow accelerated by the guide ring 5 impacts the forward-swept blade 8, the special shape of the forward-swept blade 8 can better capture the energy of the airflow.

[0087] The design of the forward-swept blades 8 allows the airflow to flow more smoothly on the blade surface, reduces airflow separation and turbulence, and thus more effectively converts the kinetic energy of the airflow into the rotational kinetic energy of the wind wheel 22, allowing the wind wheel 22 to rotate quickly and stably.

[0088] The hollow slot 6 provided in the wind wheel 22 has two main functions.

[0089] On the one hand, during the rotation of the wind wheel 22 , the hollow groove 6 allows part of the airflow to pass through the wind wheel 22 , thereby reducing the wind resistance of the wind wheel 22 as a whole.

[0090] On the other hand, the presence of the hollow groove 6 reduces the mass of the wind wheel 22. According to the formula of the moment of inertia, the reduction in mass reduces the moment of inertia of the wind wheel 22, and the wind wheel 22 can respond to changes in airflow more quickly, and the acceleration and deceleration process is faster.

[0091] The guiding and accelerating effect of the guide ring 5 on the airflow and the efficient capture of the airflow energy by the forward-swept blades 8 enable more airflow energy to be converted into the rotational energy of the wind wheel 22 .

[0092] This means that under the same airflow conditions, the wind wheel 22 can obtain a greater rotation speed and torque, thereby improving the energy conversion efficiency of the entire atomizing inhalation device and enabling the device to work more efficiently.

[0093] The hollow groove 6 reduces the rotational inertia of the wind wheel 22, so that the wind wheel 22 can quickly respond to changes in the patient's respiratory airflow.

[0094] When the patient's breathing rate speeds up or slows down, the wind wheel 22 can quickly adjust the rotation speed, so that the linear switch 26 can transmit the signal to the nebulizer 1 more quickly, thereby achieving timely adjustment of the working parameters of the nebulizer 1 and ensuring that the drug delivery amount is always well matched with the patient's breathing state.

[0095] Since the energy conversion efficiency of the wind wheel 22 is improved, the energy consumption required by the equipment will be reduced when achieving the same working effect.

[0096] At the same time, the forward-swept blades 8 reduce the turbulence of the airflow, and the hollow grooves 6 reduce the wind resistance, which helps to reduce the noise generated when the airflow flows inside the device, creating a relatively quiet use environment for patients and medical staff.

[0097] The sliding sleeve 3 is made of magnetic material, and the spring 32 is connected to a magnetic ring 33 , which has the same magnetic pole as the sliding sleeve 3 .

[0098] The repulsive magnetic force between the magnetic ring 33 and the sliding sleeve 3 makes the sliding sleeve 3 and the sliding block 31 no longer in contact, thereby reducing the movement resistance of the sliding block 31 .

[0099] The presence of magnetic force makes the sliding block 31 more sensitive to slight changes in the rotation speed of the wind wheel 22, and can trigger the linear switch 26 more quickly and accurately, thereby enabling the nebulizer 1 to adjust the working parameters more timely, thereby improving the response sensitivity of the entire anesthesia nebulization inhalation device to the patient's breathing status.

[0100] The other end of the suction tube 14 is connected to the suction port 15, which is made of flexible material. One end of a plurality of elastic diaphragms 7 is arranged in the suction port 15, and the elastic diaphragms 7 are arranged in an array. The other end of the elastic diaphragm 7 is inclined toward the suction tube 14, and a storage hoop 12 adapted to the suction port 15 is provided on the front of the atomizer 1.

[0101] When the patient uses the nebulizer inhalation device, since the inhalation port 15 is made of flexible material, it can fit the patient's mouth and nose well, providing a comfortable contact experience, while forming a relatively sealed space to reduce the leakage of drug droplets. It can also be connected to a tracheal tube through a conversion interface to ensure that the patient can effectively inhale the drug.

[0102] When the patient inhales, under the action of negative pressure, the mist droplets containing anesthetic drugs produced by the atomizer 1 flow along with the air flow through the inhalation tube 14 to the inhalation port 15.

[0103] When the breathing frequency is fast and the tidal volume is large, the negative pressure generated by inhalation is large, the elastic diaphragm 7 is greatly deformed and moved closer to each other, so that the aperture of the inhalation port 15 becomes smaller. When the drug passes through the inhalation port 15, the aperture of the inhalation port 15 becomes smaller, and the force of the airflow on the droplets increases. When this force exceeds the surface tension of the droplets, the droplets will be broken, thereby producing smaller atomized particles.

[0104] When the breathing frequency is slow and the tidal volume is small, the inhalation negative pressure is small, the elastic diaphragm 7 is deformed to a small extent, the thin sheets of the variable suction port 15 are separated from each other, the aperture of the suction port 15 becomes larger, and larger atomized particles are generated.

[0105] When the breathing rate is fast and the tidal volume is large, the airflow speed in the human respiratory tract is faster, and the smaller atomized particles can better follow the airflow into the respiratory tract, increasing the contact area between the drug and the respiratory mucosa, thereby improving the absorption efficiency of the drug. When the breathing rate is slow and the tidal volume is small, the larger atomized particles can be more easily deposited on the surface of the respiratory tract in the relatively slow airflow, which also helps the absorption of the drug.

[0106] Adjusting the size of atomized particles according to different breathing conditions can enable the drug to act more accurately on different parts of the respiratory tract, ensuring that the ideal effect can be achieved under various breathing conditions.

[0107] For example, during surgery, the patient's respiratory rate and tidal volume may change due to different stimuli or physiological states. This adaptive adjustment of atomized particles can ensure the effectiveness and stability of the drug.

[0108] By matching the breathing state to generate aerosol particles of appropriate size, drugs can be used more effectively, avoiding the inability to fully inhale and absorb drugs due to aerosol particles that are too large or too small, thereby reducing drug waste and lowering medical costs.

[0109] The appropriate size of atomized particles can better adapt to the patient's breathing state, reduce the discomfort symptoms such as choking and dyspnea caused by inappropriate particle size, and improve the patient's comfort when using atomized inhalation equipment.

[0110] The storage hoop 12 is adapted to the suction port 15 and can tightly fix the suction port 15 to prevent it from shaking or falling off during the storage process. At the same time, it plays a role in protecting the suction port 15 from damage and pollution from the outside, making it convenient to store and carry the equipment.
