Description

Artificial intelligence portable sprayer

technical field

The present invention relates to a nebulizer, and in more detail, relates to a nebulizer which grasps the state of a user by artificial intelligence and performs treatment by adjusting the amount of liquid sprayed.

Background technique

The first sprayer developed was a sprayer sprayed by using pressure and was invented by Sales-Girons in 1858. At the time, the pump of the sprayer was similar to the pump of a bicycle tire. If the pump was pulled, the liquid was sucked from the container, and if the pump was pressed by hand, the liquid was passed through the sprayer and entered into the person's mouth.

In this way, nebulizers have gradually developed from manual spraying and steam spraying to electrosprayers and ultrasonic nebulizers using electric compressors (ELECTRICAL COMPRESSOR). Currently, a nebulizer using ultrasonic vibration mesh net technology has been developed, which has advantages in low noise and reduced liquid consumption.

The use of nebulizers has a long history. Nebulizers play the role of delivering inhaled medicines for respiratory diseases to the bronchi and alveoli in the form of fine particles, and providing humidity to the airways. and other respiratory organ disease drugs to deliver the effect to the treatment site.

Because conventional nebulizers also spray medicine when exhaling, the medicine will not be absorbed into the body, and the absorption power will drop to less than 50%. In the case of acute asthma attack, it takes 1 hour, so it is not suitable for infants and young children. The problem is particularly serious. In addition, when inhaling, infants with low vital capacity cannot adjust the pressure, so the therapeutic effect is low, and for adults with large vital capacity, the effect of drug treatment decreases due to the drop in pressure, and the treatment time becomes longer. .

Most of the users who use nebulizers are patients with lung diseases and respiratory diseases. Since these patients have decreased lung capacity due to decreased lung function, it is necessary to use a nebulizer suitable for the vital capacity of the user. In addition, since the user in a drowsy state needs to operate automatically when the guard is absent, it is necessary to develop a sprayer with artificial intelligence.

Therefore, there is a need to develop a nebulizer that can perform treatment in an artificial intelligence manner by effectively using drugs and increasing lung capacity to reduce treatment time.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is an exploded perspective view showing a nebulizer according to an embodiment of the present invention.

Referring to FIG. 1 , the nebulizer 10 includes a cover part 30 , a suction part 50 , a sensing part 70 , a power supply 102 , an injector 103 , a switch 104 and an input part 105 .

The cover part 30 includes a rear cover 30a, a motor cover 30b, and a front cover 30c, and the suction part 50 includes a brushless DC motor 50a and a driver 50b.

The front cover 30c is made of polymer, ceramic or metal material, and the space where the input unit 105 is located and the space where the switch 104 is located are formed on the front cover 30c. The rear cover 30a includes filter holes and various connection parts, and the rear cover 30a is made of polymer, ceramic or metal.

The motor cover 30b is used to cover the brushless DC motor 50a, and the motor cover 30b covers the outside of the brushless DC motor 50a to prevent noise and vibration generated by the brushless DC motor 50a. The aforementioned nebulizer 10 with less noise and vibration has the advantage that it can be used in various environments such as infants and patients who are sensitive to the surrounding environment.

The brushless DC motor 50 a is formed at the lower end of the sprayer 10 and provides power for spraying liquid from the sprayer 10 .

Different from conventional AC motors, the above-mentioned brushless DC motor 50a can easily change the pressure, flow rate (FLOW RATE) (NL/m), and the driving cycle of the motor required by the user through the increase or decrease of the current. Therefore, the above-mentioned sprayer 10 is not Instead of continuously spraying liquid, the liquid is only sprayed when the user inhales. Therefore, unlike the conventional nebulizer which sprays liquid even when exhaling, causing serious waste of liquid, the above-mentioned brushless DC motor 50a has the advantage of not wasting liquid at all.

In addition, unlike an AC motor, the brushless DC motor 50a is heat-resistant and has low noise. In particular, when switching (ON/OFF), no arc is generated, so the service life is about three times that of a general AC motor. Moreover, Relative to performance, the size can be miniaturized and thus more stable.

Therefore, it has an advantage of being used for many patients in a large hospital. However, the driver 50b is additionally connected to the outside of the brushless DC motor 50a due to the limitation of the heat that the control device can withstand.

Conversely, when the brushless DC motor 50a is the AC motor, the liquid is continuously ejected, and therefore, the liquid is continuously ejected even when exhalation is performed.

However, the above-mentioned brushless DC motor 50a is expensive, so when the above-mentioned AC motor is used due to the price problem, it is possible to perform injection periodically by using a solenoid valve.

The driver 50b is a circuit for controlling the brushless DC motor 50a formed at a predetermined distance from the motor in order to avoid side effects of heat and noise from the brushless DC motor 50a.

The sensing unit 70 includes a mass flow (MASS FLOW METER) sensor 101 .

The mass flow sensor 101 is formed on the side of the brushless DC motor 50a. Since the mass flow sensor 101 is small in size and light in weight, it has little influence on the overall weight of the sprayer 10. The mass flow sensor 101 uses the mass of gas as a measurement standard, and the mass is a measurement standard whose measurement unit is not guided by other physical quantities, and forms the basis of physical measurement together with units such as length and time. Therefore, the mass flow sensor 101 has the advantage of directly measuring the above-mentioned invariant mass without complicated calculations, and can grasp an accurate gas flow rate.

In addition, it is beneficial to measure low-flow gas, because it does not measure the volume or pressure of the gas, so it can accurately measure the quality of the flowing gas.

Moreover, no device generating vibration is formed during the measurement of the gas mass, and therefore, there is an effect of increasing the convenience of the user in the process of using the above-mentioned nebulizer 10 .

The above-mentioned mass flow sensor 101 can mainly measure the mass of various gases such as carbon dioxide ( _{CO 2} ), argon (Ar), methane (Methane), hydrogen (Hydrogen) and nitrogen (Nitrogen). The complex data of the user's blood circulation, exhalation, inhalation, lung capacity and lung function can be measured by using the quality of the liquid, so that the injection volume, injection time and exhalation time of the user's special liquid can be calculated.

The above-mentioned mass flow sensor 101 is small in size and excellent in portability, and if an additional gas sensor is attached, it can measure various gases exhaled by the user. If the above-mentioned gas sensor is additionally attached, the user's disease name can be grasped by measuring the gas volume of specific and various gases exhaled by the user suffering from various diseases.

Therefore, by attaching the above-mentioned mass flow sensor 101, the above-mentioned nebulizer 10 derives the analysis results in a measurement method specific to the user and autonomously judges the state of the user to grasp the overall state of the user, not just for simple pulmonary function therapy, and The nebulizer 10 has the advantage of being an artificial intelligence nebulizer by making the user inhale the medicine corresponding to the above-mentioned condition through the nebulizer 10 for treatment.

The above-mentioned power supply 102 uses a medical power supply, which can be used in a voltage-changing manner, and has advantages in terms of stability and convenience.

The injector 103 stores liquid, and when the injection port of the injector 103 enters the mouth, the injector 103 injects the liquid periodically and gradually by the drive of the brushless DC motor 50a. The sprayer 103 is formed on the outside of the sprayer 10, and is hung on the outside of the sprayer 10 in a manner that it can be detached for spraying at any time for the convenience of the user.

The above-mentioned switch 104 is formed on the upper end of the above-mentioned front cover 30c, and is used for turning on the power supply or used as an emergency button in an emergency when the spraying needs to be stopped suddenly.

The input unit 105 includes a touch panel or an ordinary panel, and a plurality of buttons can be formed at the position where the input unit 105 is installed to select the respiration level according to age. Since the input unit 105 is formed of a touch panel, the user can make an intuitive selection, and there is an advantage that there is no need to bother about extra difficult explanations and operation methods.

Fig. 2 is an exploded perspective view showing the sprayer of Fig. 1 viewed from another direction.

Referring to FIG. 2 , the nebulizer 10 includes a filter 106 , a universal serial bus (USB) terminal 107 , a power switch 108 and a control device 109 . The above-mentioned filter 106 is formed inside the nebulizer, and when the user inhales, the filter 106 has the characteristic of purifying the air. The above-mentioned universal serial bus terminal 107 is formed on the lower part of the above-mentioned filter 106, so that it can be read in a personal computer by downloading the use time of the user, etc., and the above-mentioned universal serial bus terminal 107 is used to update the inside of the sprayer 10 program.

A power switch 108 is formed at the lower end of the USB terminal 107 , and the USB terminal 107 is connected to a control device 109 . Above-mentioned nebulizer 10 can be connected with personal computer through above-mentioned universal serial bus terminal 107, can be used for uploading the record of user, and the data measured by above-mentioned mass flow sensor 101 and user's inhalation and exhalation can be checked by personal computer. time etc. for analysis.

In addition, when the user is using the nebulizer 10, the gas exhaled by the user is measured and analyzed in real time by the mass flow sensor 101, so that the state of the user can be confirmed through the personal computer.

The power switch 108 is a switch for connecting the nebulizer 10 to a power source and initially driving the nebulizer 10 . The control unit 109 analyzes the injection time ratio for improving the user's cardiopulmonary activity, and controls the brushless DC motor 50a through the driver 50b to adjust the liquid injection time based on the analysis information.

Therefore, the control device 109 transmits a suction signal for periodically sucking air to the driver 50b separately installed outside the brushless DC motor 50a, which is set in the nebulizer 10. Periodic and intermittent pumping movements corresponding to the number of breaths per minute.

The power supply 102, the injector 103, the filter 106, and the brushless DC motor 50a maintain their original functions and have a minimum volume, thereby improving the portability of the sprayer 10.

Table 1

Table 2

Table 1 shows the breath number stages by age and the range of breaths per minute corresponding to the above breath number stages, and Table 2 shows the injection time ratio and pressure based on the flow increase stage.

The numerical values in the above-mentioned Table 1 and Table 2 can be changed by the user, and the above-mentioned numerical values are used for the convenience of description.

Referring to Table 1, the stages of the above-mentioned respiration rate are divided by age, and different ranges of the above-mentioned respiration rate per minute are respectively indicated according to each age.

Referring to Table 2, the above-mentioned flow increase stage can be divided into multiple stages, and the above-mentioned flow increase stage enters the next stage as the set time exceeds.

The respiration per minute represents the sum of inhalation and exhalation performed within one minute, and the respiration rate stage is automatically set by judging the respiration per minute of the user measured by the mass flow sensor. For example, if the measured respiration rate per minute of the user is 15, and the set age of the user is 18 years or older, then the respiration rate stage is set as an adult. Alternatively, the user can manually set through the input unit 105 . The above-mentioned flow rate increase stage means that the above-mentioned injection time ratio enters the next stage, and the sub-unit can be set as an hour unit.

After measuring the respiration rate per minute of the user measured by the mass flow sensor 101 , the control device 109 sets the stage corresponding to the respiration rate of the user.

The injection time ratio indicates the ratio of the injection time from the injector 103 during the intake period. For example, in the above-mentioned respiration count stage, when the user is set as an adult, and the time of the above-mentioned flow increase stage is set to 1 minute, if the above-mentioned respiration count per minute is 12 times, the inhalation The number of times is 6 times.

Therefore, the time required to perform one inhalation is 5 seconds. At this time, the above-mentioned flow rate increase stage starts from the first stage, and the set one minute needs to be consumed in order to enter the second stage from the above-mentioned first stage. The above-mentioned injection time ratio is 1 in the above-mentioned first stage.

If the injection time ratio is 1, the injector 103 will inject within 5 seconds of air intake. When entering the second stage after 1 minute, the injection time ratio is changed to 1.1, so that the injector 103 injects within 5.5 seconds of air intake. When 1 minute passes again, enter the third stage and change the above-mentioned injection time ratio to 1.2, so that the time for inhalation, that is, the injection time of the liquid is increased to 6 seconds. The above exhalation time ratio is also set in the same manner as the method for applying the above injection time ratio.

As mentioned above, according to the above-mentioned injection time ratio, the exhalation time or the injection time of the liquid is increased by each of the above-mentioned injection time ratio stages, and the user is affected by the increased liquid injection time due to the use of the above-mentioned nebulizer 10 for hours or days. Guided by it, it will naturally increase the inhalation time and exhalation time.

If the inspiratory time becomes longer because the user has used the nebulizer 10 for several days, the user will naturally form the habit of abdominal breathing or long-term inhalation and exhalation. Also, due to the increased inhalation time, the effect of improved blood circulation and lung capacity can be naturally obtained. In addition, the nebulizer 10 has the advantage of being able to induce natural respiration for patients or infants whose lung function is reduced due to sequelae after surgery.

The exhalation time ratio indicates a time ratio at which the injector 103 stops ejection. Due to the aforementioned proportion of exhalation time which increases with the time the nebulizer 10 is used, the exhalation period during which the user exhales also increases. During the increased exhalation time, the user expels unnecessary gases in the human body, such as CO ₂ , so that the lung function and lung capacity can be improved.

Different time periods for the above-mentioned flow rate increase stages can be applied to each stage, and the same time period for the above-mentioned flow rate increase stage can also be used for each stage.

In addition, the above-described guiding function for prolonging the exhalation time of the nebulizer 10 can be applied not only to the nebulizer 10 but also to various nebulizers such as ultrasonic nebulizers.

Moreover, the above-mentioned functions are not limited to nebulizers, but can be applied to products used to increase lung capacity, and can also be applied to lung cancer patients, athletes, rhinitis patients, users who want to improve Dantian or abdominal breathing, depression patients and psychiatrists patient.

In the case of lung cancer patients, improving part of the lung function can make the patient breathe normally and smooth the blood circulation, which can be helpful for the treatment of lung cancer.

In the case of an athlete, the lung function can be exercised by exercising during the day, and the lung function can also be exercised by adding the above-mentioned nebulizer 10 or the above-mentioned guide function of the exhalation time during sleep.

For patients with rhinitis, by increasing the guiding function of the above-mentioned exhalation time, it can enhance immunity and smooth the blood circulation of the whole body and nose, thereby having the effect of self-curing rhinitis.

For users who practice dantian or abdominal breathing, by adding the above-mentioned function of guiding breathing time, lung function can be improved and abdominal breathing can also be guided during sleep, thereby increasing the effect based on dantian and abdominal breathing.

For students or disabled people who need to concentrate, increasing the guiding function of the above-mentioned inhalation time can improve lung function and smooth blood circulation, which is not only beneficial for students to concentrate on learning, but also beneficial to health.

In the case of psychiatric patients, blood circulation to the brain is improved by guiding steady breathing, and a healthy physical state is formed. Therefore, the stability of the body leads to the stability of the mind, and it has an effect of reducing anxiety, depression, and the like of psychiatric patients.

In the case of using the above-mentioned brushless DC motor 50a, the above-mentioned control device 109 is separated from the above-mentioned brushless DC motor 50a and transmits the setting of the above-mentioned respiration per minute, the above-mentioned injection time ratio and the above-mentioned flow rate increase stage to the connected above-mentioned driver 50b. fixed value, so as to control the brushless DC motor 50a. In this case, the brushless DC motor 50a sucks liquid only in the presence of the signal of the driver 50b controlled by the control device 109, so there is an advantage of less consumption of the liquid.

If the time for the user to inhale increases, when it is considered that most patients use the above-mentioned nebulizer 10, it will have a great impact on rehabilitation due to the increase of oxygen saturation based on long-term exhalation and the influence of blood circulation and abdominal respiration. influences. In the case of a patient, after the operation, the lung function is not smooth due to the influence of anesthesia and the sequelae of the operation, so the guidance function that increases the exhalation time has a great effect of shortening the recovery time of the patient.

Unlike conventional nebulizers, the nebulizer 10 including the mass flow sensor 101 can grasp the state of the user by analyzing exhaled, inhaled, and exhaled gas, thereby reducing the trouble of setting through the input unit 105 . In addition, when the above-mentioned respiratory rate per minute becomes fast or slow due to a sudden change in the state of the patient, the above-mentioned mass flow sensor can also measure in real time to eject the liquid in accordance with the user's inhalation, and The above breaths per minute can be adjusted.

Furthermore, the aforementioned mass flow sensor 101 is applicable not only to the aforementioned nebulizer 10 but also to various types of nebulizers, thereby performing the function of artificial intelligence.

The above-mentioned nebulizer 10 is connected to a personal computer through the above-mentioned universal serial bus terminal 107. After the above-mentioned mass flow sensor 101 analyzes the gas produced when the user exhales, when the user's health condition deteriorates, it can send The guard who goes out transmits a warning message or reminds.

Fig. 3 is an image showing a driving screen on the input unit of the nebulizer of Fig. 1 .

The driving screen 500 generally includes breathing information 501 and a device setting window 502 . The respiratory information 501 includes the number of respirations per minute 501a, the volume of one breath 501b and the number of respirations per hour 501c, and the above-mentioned device setting window 502 includes indoor temperature 502a, respiration number stage 502b, adjustment button 502c, driving time 502d, pressure button 502e , inspiratory time 502f, exhalation time 502g and start button 502h.

The respiration per minute 501a indicates the total of exhalation and inhalation for one minute, and the breath volume per breath 501b indicates the amount of gas exhaled or inhaled when exhaling or inhaling. The breathing rate per minute 501a and the breathing volume per breath 501b are numerical values that can detect the current state of the user in a short time.

The respiration rate per hour 501c represents the total of exhalation and inhalation per hour, and the respiration rate per hour 501c is a numerical value that can be used to check whether the condition of a patient who cannot be detected frequently is getting better or not.

The indoor temperature 502a indicates the indoor temperature of the nebulizer 10 being used by the user, and it is possible to detect the temperature as an important adjustment factor in order to improve the condition of the user who has undergone surgery or has weak bronchi.

The respiration rate stage 502b is formed by a plurality of buttons, and the respiration rate stage 502b is selected according to the respiration rate per minute 501a of the user. If one of the breath count stages 502b is selected, the liquid is sprayed at a count corresponding to half of the breath count 501a of the user. For example, if the user selects the breathing rate stage 502b for an adult, the breathing rate per minute 501a is 10, and spraying is performed 5 times within 1 minute. Therefore, 5 sprays are performed in 6 seconds corresponding to the exhalation, and the user is asked to inhale within 6 seconds of spraying the liquid within 1 minute.

The number of buttons in the breathing count stage 502b is not limited to three, but can be formed by multiple buttons.

The adjustment button 502c is a button for adjusting set values such as pressure and time, and the start button 502h is a button for starting the driving of the nebulizer 10 after setting.

The driving time 502d indicates the time when the user uses the nebulizer 10 . The user inputs the time spent using the nebulizer 10 in minutes.

The above-mentioned pressure button 502e indicates the pressure of the liquid sprayed to the respiratory organ of the user, and the user can set it within a predetermined range.

The exhalation time 502g indicates the exhalation time of the user, that is, the exhalation time, and the exhalation time can be set in units of seconds. The aforementioned exhalation time 502g can be set within the range of 1 second to 10 seconds.

The start button 502h is a button for starting the driving of the nebulizer 10 after the device setting window 502 is set.

The button is used to manually operate the nebulizer 10 , mainly based on the data of the respiration per minute analyzed by the mass flow sensor 101 to set the respiration stage suitable for the user.

Fig. 4 is a block diagram showing a driving method of the nebulizer shown in Fig. 1 .

The power switch 108 is turned on to operate the power source 102 to drive the nebulizer 10 (step S101).

The user bites the injector 103 and breathes for 1 to 3 minutes (step S102).

The data of the user's respiration per minute, gas produced during exhalation, and exhalation time measured by the mass flow sensor 101 are transmitted to the control device 109 (step S103).

The above-mentioned control device 109 transmits signals related to the suction cycle and pressure to the above-mentioned driver 50b after analyzing the above-mentioned breaths per minute, injection time ratio, exhalation time ratio and pressure applicable to the user by analyzing the above-mentioned signals. (step S104).

The driver 50b transmits to the brushless DC motor 50a a suction signal corresponding to the breathing rate per minute, the flow increase stage, the pressure, and the injection time ratio (step S105 ).

The brushless DC motor 50a performs suction with the injector after receiving periodic signals from the driver 50b relating to the breathing rate per minute, the flow increase stage, pressure, and the injection time. In the brushless DC motor 50a, since the filter and the pressure gauge are combined, the incoming air is purified and suctioned at a set pressure (step S106).

The user inhales through the mouth or nose the liquid ejected from the injector 103 at a predetermined cycle for a predetermined time, and as the time set by the user exceeds, the above-mentioned flow rate increase stage is sequentially performed. The ejection time of the liquid that is gradually increased in accordance with the above-mentioned ejection time ratio that increases stepwise is guided so that the user's inhalation time can be increased (step S107 ).

The patient's inhalation and exhalation, respirations per minute, respiration stages, and the overall state of the patient can be grasped through the input unit (step S108).

According to the embodiment of the present invention as described above, unlike conventional sprayers, the above-mentioned sprayer 10 periodically sprays the above-mentioned liquid to the user only within a predetermined time by using the above-mentioned mass flow sensor 101 and the above-mentioned brushless DC motor 50a, And the state of the user can be grasped in real time to apply the above breaths per minute suitable for the breathing state of the user. Therefore, unnecessary waste of the above-mentioned liquid is prevented, and liquid ejection can be performed in a manner most suitable for the user.

Furthermore, the motor cover 30b covers the brushless DC motor 50a, and the motor cover 30b covers the outside of the brushless DC motor 50a to prevent noise and vibration generated in the brushless DC motor 50a. The aforementioned nebulizer 10 with less noise and vibration has the advantage that it can be used in various environments such as infants and patients who are sensitive to the surrounding environment.

The above-mentioned mass flow sensor 101 is small in size and light in weight, and is measured based on the mass of the gas exhaled by the user instead of the volume of the gas, so that the correct gas flow rate can be grasped. In addition, there is no device that vibrates during the measurement of the gas mass. Therefore, the user's convenience is increased during the use of the nebulizer 10 .
