Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and relates to the innovation and improvement of a micro-mesh atomizer and an atomization system. Specifically, it is an intelligent micro-mesh atomizer and an atomization system. Background Art

[0002] In atomization inhalation therapy, the liquid medicine is dispersed into micron-sized fine misty liquid particles by an atomizer, and reaches the patient's lungs through the patient's respiratory tract, so as to achieve the purpose of painless and rapid treatment of diseases such as cough, asthma, sore throat, pharyngitis, and bronchopneumonia. The main device for atomization inhalation therapy is a micro-mesh atomizer, which is composed of a liquid medicine cup, an atomization sheet, a spray nozzle, and a controller. Its core component is the atomization sheet. The atomization sheet is composed of a piezoelectric ceramic and a micro-mesh sheet. The piezoelectric ceramic generates mechanical energy under the excitation of an electrical signal source, drives the micro-mesh sheet to vibrate, so as to achieve the purpose of fogging. This atomization method does not affect the local air pressure, has low power consumption and high fogging efficiency.

[0003] In the IUC ward, atomization therapy is also often used, and it is often used in combination with a ventilator or an anesthetic machine. Since the ventilator needs to monitor the patient's breathing state, the gas passage composed of the breathing pipeline and the patient's respiratory tract must be airtight. Therefore, it is required that the atomizer used in combination with the ventilator or anesthetic machine does not allow the air pressure in the ventilator pipeline to be affected, otherwise it is easy to cause misjudgment or alarm of the ventilator. The micro-mesh atomizer extrudes the liquid medicine from the micro-mesh by means of the micro-mesh vibration of the micro-mesh atomization sheet to form an aerosol, which does not affect the local air pressure. Therefore, it is the most suitable atomizer for the application scenario in combination with a ventilator or an anesthetic machine. When the micro-mesh atomizer is used in combination with a ventilator, it is mainly placed at the air inlet end of the humidifying tank pipeline of the ventilator or at the patient's inhalation pipeline of the Y-shaped joint of the ventilator pipeline, that is, the ventilator outlet pipeline end. Since there is still a certain distance between the position where the atomizer is arranged on the ventilator pipeline and the patient's respiratory tract, this distance is connected to the patient's respiratory tract through the ventilator pipeline. Part of the drug particles atomized by the micro-mesh atomizer will remain on the inner wall of this ventilator pipeline and form a liquid, reducing the drug delivery amount. And the existing micro-mesh atomizers are all connected to the ventilator pipeline and continuously fog after starting atomization. Whether the patient inhales or exhales, the micro-mesh atomizer is working and spraying. At this time, part of the aerosol generated when the micro-mesh atomizer works will enter the respiratory tract with the patient's inhalation, and the other part will be wasted in the ventilator pipeline with the patient's exhalation. Therefore, the drug delivery amount of the existing micro-mesh atomizer used in combination with a ventilator is very low, and the drug waste is serious.

[0004] When the micromesh nebulizer is used in conjunction with a ventilator, it is mainly connected to the ventilator pipeline through a T-type three-way connector. The T-type three-way connector equipped by existing micromesh nebulizer manufacturers is a right-angle connection. The aerosol sprayed by the micromesh nebulizer directly hits the T-type three-way connector and the wall of the ventilator connection passage, increasing the probability of contact between the aerosol and the inner wall of the T-type three-way connector pipeline, causing part of the aerosol to hit the inner wall of the pipeline to form droplets that cannot be delivered to the patient's respiratory tract, causing a certain amount of drug loss and reducing the delivery amount.

[0005] Patients with lung or respiratory diseases usually have abnormal breathing symptoms such as shortness of breath and rapid breathing. Existing nebulizers do not have a targeted solution for such patients. Nebulizer medication relies entirely on the patient's spontaneous breathing and cannot guide the patient to standard breathing. There is no guidance for nebulizer medication and a lack of behavioral promotion for the patient's respiratory rehabilitation.

[0006] How to design an intelligent microgrid nebulizer and nebulization system so that it has the following advantages and effects: (1) timely adjust the spray state according to the patient's breathing condition. When the patient inhales, the nebulizer sprays normally; when the patient exhales, the nebulizer stops spraying; (2) it can also guide the patient to perform standard breathing, allowing the patient to receive nebulization treatment with higher efficiency and quality; (3) increase the drug delivery amount, enhance the treatment effect, reduce drug waste, improve drug utilization efficiency, and reduce the cost of treatment drugs. This is a technical problem that needs to be solved urgently in this field. Summary of the invention

[0007] In order to solve the above-mentioned problems existing in the prior art, the present invention provides an intelligent microgrid nebulizer and atomization system, which can control the mist output rhythm of the nebulizer according to the patient's breathing state to achieve intelligent drug delivery; further, the patient's breathing state can be monitored, and a standard reference breathing guide can be provided to the patient according to the patient's physical condition, thereby improving the nebulization quality control level, increasing the nebulization delivery dose, reducing the amount of medicine used, and thus reducing the cost of medicine use.

Standard Luer interfaces or customized interfaces are arranged at both ends of the pressure extension tube. One end of the pressure extension tube is connected to the gas passage interface on the chamber of the spray nozzle in a matching manner, and the other end of the pressure extension tube is connected to the respiration monitoring module, and a gas passage is constructed. A sampling interface is arranged on the respiration monitoring module, and the sampling interface adopts a standard Luer interface or a customized interface to communicate the sampling interface of the respiration monitoring module with the air pressure in the chamber of the spray nozzle.

[0011] Further improvement to the above technical solution: The respiration monitoring module uses a barometric pressure sensor or a gas flow sensor and a temperature sensor as respiration monitoring sensors. The sensing surface of the respiration monitoring sensor and the sampling interface led out on the respiration monitoring module form a sealed gas channel. The respiration monitoring sensor is arranged at the inner end of the sampling interface and is sealed by a sealing ring. The respiration monitoring module monitors the patient's respiration state by monitoring the air pressure change or flow change in the chamber of the spray nozzle, and calibrates the air pressure or flow by monitoring the temperature in the chamber of the spray nozzle.

The indicator lights include a group of indicator lights that indicate the patient's respiration state by lighting and extinguishing and a group of indicator lights that indicate the working mode of the respiration monitoring module. The buttons are used to turn off and turn on the respiration monitoring module, and adjust and select the working mode of the respiration monitoring module.

[0013] Further improvement to the above solution: The controller is equipped with an atomization control line and a USB data line. The USB data line uses a USB-A interface and is used to connect to a USB host or a power adapter that meets the requirements of the USB Alliance specification and can output USB power externally. The controller is built-in with a rechargeable battery, which is charged through the USB data line or provides working power for the device. The controller is equipped with an RTC and a storage module, and the storage module is used to store the patient's breathing status and the operation records of the patient on the controller.

[0014] Further improvement to the above solution: The controller is equipped with wireless communication and wired communication modules. The wireless communication includes Bluetooth, ZigBee, LORA, and NB-IOT wireless communication methods. The wired communication module includes USB, UART, RS232, RS485, and CAN wired communication methods. The wireless communication and wired communication modules have downlink communication and uplink communication functions. The downlink communication refers to communication with the breathing monitoring module or the medicine cup.

[0015] Further improvement to the above solution: The controller is equipped with multiple atomization timing gears and multiple atomization rate gears, and also has a cleaning mode. The atomization timing gears and atomization rate gears can be adjusted and switched with the cleaning mode. The controller is equipped with a multifunctional button and several status indicator lights.

[0016] Further improvement to the above solution: The T-shaped tee joint includes a spray nozzle interface, an intake breathing pipeline interface, and an outlet breathing pipeline interface. The axis of the spray nozzle interface forms an angle of 60° to 80° with the axis of the intake breathing pipeline interface.

[0017] An intelligent micro-network atomization system of the present invention includes a micro-network atomizer, a host computer, and a cloud server. It is characterized in that the micro-network atomizer is the intelligent micro-network atomizer described above. The host computer includes a screen, a sound generating unit, and a communication module. The host computer is used to communicate with the controller in the intelligent micro-network atomizer, read the patient's breathing status and the controller operation records. When the spray nozzle and the medicine storage tank cooperate, the breathing detection module monitors the patient's breathing status and the air temperature in the medicine storage tank, and the controller uploads the patient's breathing status to the host computer. The screen and the sound generating unit on the host computer are used to prompt, guide, or instruct the user to perform accurate and standard breathing.

[0018] Further improvement of the above solution: The host computer includes a smart phone, a tablet computer, a computer, a ventilator, an anesthetic machine or a smart terminal controlled by a cloud server. The intelligent micro-network atomizer is used in cooperation with a ventilator or an anesthetic machine. The breathing state of the patient is monitored through the breathing monitoring module. The controller controls the intelligent micro-network atomizer to spray only when the patient inhales by reading the breathing state of the patient.

[0019] The advantages and positive effects of the present invention are:

[0020] 1. By adding the patient breathing monitoring function to the atomization system, the present invention can obtain the breathing state of the patient in real time, and can dynamically adjust the working state of the atomizer according to the breathing state of the patient to achieve intelligent drug delivery.

[0021] 2. The present invention can adapt to various atomization scenarios. When the atomization system is used in cooperation with a holding chamber, it can be applied to general wards, ICU wards and special atomization rooms in hospitals, and can also be applied to home treatment of patients. Since the present invention integrates the breathing monitoring and the atomization system into a whole, it can monitor the breathing state of the patient in real time, and is especially suitable for breathing problems caused by abnormal breathing and other diseases caused by the patient's respiratory lesions. The introduction of breathing monitoring can upload the breathing state of the patient to the host computer in real time. The host computer uses the display screen and the sound generating unit to guide the patient to breathe correctly and standardly with sound and images, which can accelerate the recovery speed of the patient and improve the treatment quality. When the atomization system is used in cooperation with a ventilator or an anesthetic machine, the breathing state of the patient can be monitored through the breathing monitoring module, and the atomizer can be controlled to fog only when the patient inhales and stop fogging when the patient exhales, reducing the waste of drugs, increasing the drug delivery amount, reducing the use amount of the drug mist, and cooperating with the T-shaped three-way joint equipped in the atomization system of the present patent, which can reduce the probability of the aerosol generated by the atomizer colliding with the wall of the T-shaped three-way joint, and further reduce the residual amount of the aerosol generated by the atomizer adhering to the wall, so as to further improve the delivery dose and reduce the waste of drugs.

Detailed implementation manners

[0033] The present invention will be further described in detail below with reference to the accompanying drawings:

[0034] See Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8, Embodiment 1 of an intelligent micro-network atomizer of the present invention includes a liquid medicine cup 10.10, an atomization sheet 10.6, a spray nozzle 10.2, a T-shaped three-way joint 14, and a controller 12. A controller socket 10.9 is provided at the bottom of the liquid medicine cup 10.10. The spray nozzle 10.2 is connected to the T-shaped three-way joint 14 and forms an air flow channel for communicating with the patient's respiratory tract through a pipeline. A gas passage interface 10.1 is provided on the outer wall of the spray nozzle 10.2. The gas passage interface 10.1 is in communication with the chamber of the spray nozzle 10.2. The gas passage interface 10.1 adopts a standard Luer interface or a customized interface. A jack or a pin is provided on the controller socket 10.9. One end of a plug of an atomization control line 12.1 is inserted into the controller socket 10.3, and the other end of the atomization control line 12.1 is connected to the controller 12. A respiration monitoring module 11 is provided on the atomization control line 12.1. The respiration monitoring module 11 is connected to the controller 12. The controller 12 receives the output signal of the respiration monitoring module 11 and adjusts the working state and atomization intensity of the atomization sheet 10.6 according to the received output signal. The above-mentioned respiration monitoring module 11 can also be provided in the above-mentioned air flow channel.

[0035] Furthermore, a pressure extension tube 13 is also included in the intelligent micro-network atomizer. Pressure extension tube interfaces 13.1 are provided at both ends of the pressure extension tube 13. The pressure extension tube interfaces 13.1 adopt a standard Luer interface or a customized interface. One end of the pressure extension tube 13 is connected to the gas passage interface 10.1 on the chamber of the spray nozzle 10.2 in a matching manner. The other end of the pressure extension tube 13 is connected to the respiration monitoring module 11 and constructs a gas passage. A sampling interface 11.1 is provided on the respiration monitoring module 11. The sampling interface 11.1 adopts a standard Luer interface or a customized interface. The sampling interface 11.1 of the respiration monitoring module 11 is in communication with the air pressure in the chamber of the spray nozzle 10.2 through the pressure extension tube 13.

[0036] Still further, the above-mentioned respiration monitoring module 11 uses a barometric pressure sensor or a gas flow sensor and a temperature sensor as respiration monitoring sensors. The sensing surface of the respiration monitoring sensor and the sampling interface 11.1 led out on the respiration monitoring module 11 form a sealed gas channel. The respiration monitoring sensor is arranged at the inner end of the sampling interface 11.1 and is sealed by a sealing ring. The key to detecting the patient's respiration state is that the spray nozzle 10.2 is in communication with the patient's respiratory tract. The pressure extension tube 13 communicates the air pressure in the spray nozzle 10.2 with the sampling interface 11.1, so as to transfer the changing air pressure and air flow to the sensing surface of the respiration monitoring sensor in the sampling interface 11.1, thereby monitoring the patient's respiration state.

[0037] Furthermore, a key 11.3 and an indicator light 11.2 are provided on the above-mentioned respiration monitoring module 11. The indicator light 11.2 includes a group of indicator lights for indicating the patient's respiration state by lighting and extinguishing and a group of indicator lights for indicating the working mode of the respiration monitoring module. The key 11.3 is used to turn on and off the respiration monitoring module and adjust and select the working mode of the respiration monitoring module 11.

[0038] Furthermore, in addition to the atomization control line 12.1, a USB data line 12.2 is provided on the above-mentioned controller 12. The USB data line 12.2 uses a USB-A interface and can be connected to any USB host or power adapter that meets the requirements of the USB Alliance specification and can output USB power externally, and can provide power for an intelligent micro-network atomizer of the present invention.

[0039] Furthermore, in order to enable an intelligent micro-network atomizer of the present invention to still provide atomization treatment for patients in the absence of an external power supply, a rechargeable battery is provided in the controller 12 and can be charged through the USB data line 12.2. The above-mentioned controller 12 is equipped with an RTC and a storage module, and the storage module is used to store the patient's respiration state and the operation record of the patient on the controller.

[0040] Furthermore, the above-mentioned controller 12 is equipped with wireless communication and wired communication modules. The controller 12 communicates with the respiration monitoring module 11 wirelessly or wiredly. The wireless communication includes Bluetooth, ZigBee, LORA, and NB-IOT wireless communication methods, and the wired communication includes USB, UART, RS232, RS485, and CAN wired communication methods. The controller 12 supplies power and communicates for the respiration monitoring module 11 through the atomization control line 12.1. The controller 12 controls the respiration monitoring module 11 and reads the respiration monitoring data on the respiration monitoring module 11, and uploads the device operation information and the patient's respiration state to the host computer or the cloud server.

[0041] Furthermore, the above-mentioned controller 12 has multiple atomization timing gears and multiple atomization rate gears, and also has a cleaning mode. The atomization timing gears and the atomization rate gears can be adjusted and switched with the cleaning mode. A multifunctional key 12.4 and several status indicator lights 12.3 are also provided on the controller 12. The multifunctional key 12.4 is used to control power on and off, device reset, atomization timing gears, atomization rate gears, cleaning mode, and mode switching. The status indicator lights 12.3 are at least used to indicate that the device is in the atomization timing gear, the atomization rate gear, and the cleaning mode, and the status indicator lights 12.3 are also used for battery power and fault indication.

[0042] Preferably, the above-mentioned T-shaped three-way joint 14 is as Figure 3As shown, the axis E of the nozzle interface 14.1 provided on the T-shaped tee joint 14 and the axis F of the intake breathing pipeline 14.2 form an angle α, and the angle of α is an angle of 60° to 80°, preferably 76°. In this way, the probability that the aerosol ejected by the nozzle 10.2 impacts the inner wall of the T-shaped tee joint 14 can be reduced, and the aerosol loss can be reduced.

[0043] See Figure 1 、 Figure 2 To further illustrate the usage of the intelligent micro-network atomizer in Embodiment 1, the common application methods of the intelligent micro-network atomizer will be described in detail. When the intelligent micro-network atomizer in this Embodiment 1 is used in conjunction with a ventilator, it includes at least a medicine cup 10.10, an atomization sheet 10.6, a nozzle 10.2, a respiration monitoring module 11, a pressure extension tube 13, a T-shaped tee joint 14 and a controller 12, and is also equipped with a Y-shaped tube 15 with a Y-shaped tube air inlet 15.1 and a Y-shaped tube air outlet 15.2. Insert the nozzle 10.2 into the nozzle interface 14.1 of the T-shaped tee joint 14, insert the Y-shaped tube air inlet 15.1 into the outlet breathing pipeline interface 14.3, insert the Y-shaped tube air outlet 15.2 into the air extraction end 19 of the ventilator pipeline, insert the intake breathing pipeline interface 14.2 of the T-shaped tee joint 14 into the air compression end 20 of the ventilator pipeline. The air extraction end 19 and the air compression end 20 of the ventilator pipeline are respectively connected to the corresponding interfaces of the ventilator. An air flow channel is formed by the G end of the Y-shaped tube 15 and the patient's respiratory tract, isolating it from the external air pressure.

[0044] See Figures 3-6 and Figure 7 In Embodiment 2 of an intelligent micro-network atomizer of the present invention, Embodiment 2 has most of the same structures as the above-mentioned Embodiment 1. The difference is that in Embodiment 2, the T-shaped tee joint 14 in Embodiment 1 is replaced by a storage mist can 16. The nozzle 10.2 in Embodiment 2 and the storage mist can 16 form an air flow channel for connecting the patient's respiratory tract through a pipeline. The storage mist can 16 is provided with a storage mist can inlet 16.1 and a storage mist can outlet 16.2.

[0045] Regarding the usage of the intelligent micro-network atomizer in Embodiment 2, when it is used in conjunction with a patient through an atomization mouthpiece 17, the intelligent micro-network atomizer includes at least a medicine cup 10.10, an atomization sheet 10.6, a nozzle 10.2, a respiration monitoring module 11, a pressure extension tube 13, a storage mist can 16 and a controller 12. The storage mist can outlet 16.2 is docked with the atomization mouthpiece 17, and an airtight channel is formed with the patient's respiratory tract through the atomization mouthpiece 17, as Figure 3 and Figure 4 shown.

[0046] See Figure 8 、 Figure 9, an embodiment of an intelligent microgrid atomization system of the present invention includes a microgrid atomizer, a host computer 18, and a cloud server. The microgrid atomizer is the intelligent microgrid atomizer of the above embodiment. The host computer 18 includes a screen, a sound generating unit, and a communication module. The host computer 18 is used to communicate with the controller 12 in the intelligent microgrid atomizer, read the patient's breathing state, and the controller operation record. When the spray nozzle 10.2 cooperates with the storage tank 16, the breathing detection module 11 monitors the patient's breathing state and the air temperature in the storage tank 16, and uploads the patient's breathing state to the host computer 18 through the controller 12. The screen and the sound generating unit on the host computer 18 are used to prompt, guide, or instruct the user to perform accurate and standard breathing.

[0047] Further, the above host computer 18 includes a smart phone, a tablet computer, a computer, a ventilator, an anesthetic machine, or an intelligent terminal controlled by a cloud server. The intelligent microgrid atomizer is used in cooperation with a ventilator or an anesthetic machine. The breathing state of the patient is monitored through the above breathing monitoring module 11. The controller 12 controls the intelligent microgrid atomizer to spray only when the patient inhales by reading the patient's breathing state.

[0048] To further illustrate an intelligent microgrid atomization system of the present invention, the usage of the intelligent microgrid atomization system will be described in detail. Refer to Figure 2 , Figure 4 , Figure 6 , Figure 8 and Figure 9 , the key to an intelligent microgrid atomization system of the present invention for monitoring a patient's breathing is that the spray nozzle 10.2 forms a pressure connection with the patient's respiratory tract through a pipeline. The gas passage interface 10.1 established on the spray nozzle 10.2 is connected to the breathing monitoring module 11 through a pressure extension tube 13, and finally the air pressure in the patient's respiratory tract is connected to the breathing monitoring module 11, forming an airtight channel that is relatively isolated from the external air pressure and sealed.

[0049] The controller 12 reads the data monitored by the breathing monitoring module 11 through downlink communication, judges the patient's breathing state, stores the patient's breathing state in the storage module in the controller 12, and at the same time uses the uplink communication function to transmit the patient's breathing state to the host computer 18 or the cloud server, or directly uploads the data to the cloud server through the controller 12.

[0050] When the intelligent micro-network atomizer in this intelligent micro-network atomization system is connected to the patient's respiratory tract through the fog storage tank 16 and the atomizing mouthpiece 17, the controller 12 reads the data monitored by the respiratory monitoring module 11, judges the patient's respiratory state, and uploads the patient's respiratory state to the host computer 18 and the cloud server. Information such as the patient's age, race, gender, and condition is carried on the host computer 18 or the cloud server. The host computer 18 or the cloud, through the patient's information, prompts and guides the patient to breathe standardly and correctly through the screen or sound generating unit on the host computer 18, so as to accelerate the patient's respiratory rehabilitation.

[0051] When the intelligent micro-network atomizer in this intelligent micro-network atomization system is connected to the patient's respiratory tract through the T-shaped three-way joint 14, the ventilator and the pipeline to form an air flow channel, the controller 12 monitors the patient's respiratory state through the respiratory monitoring module 11, and uploads the patient's respiratory state to the host computer 18 or the cloud server. The host computer and the cloud server will timely and efficiently control whether the atomizing sheet 10.6 sprays and the spraying rate through the controller 12 according to the patient's state, so as to realize efficient drug delivery in coordination with breathing and application. The intelligent micro-network atomizer, the host computer 18 and the cloud server form an intelligent atomization system. The advantage of doing this is that it can accurately upload the patient's respiratory data to the host computer 18 or the cloud server, which helps to record the patient's respiratory data and form an electronic medical record, bringing an excellent solution to the Internet hospital and the medical and health field, thus realizing benefits for patients and doctors. It is an intelligent micro-network atomization system that is efficient, Internet of Things-enabled, easy to use, and adaptable to various application scenarios.

[0052] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those of ordinary skill in the art within the scope of the essence of the present invention also belong to the protection scope of the present invention.
