Description

{PORTABLE SUCTION PUMP OF ARTIFICIAL INTELLIGENCE TYPE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a suction device, and more particularly, to a suction device for automatically grasping foreign substances generated in a user's respirator and sucking the same.

The medical suction unit is a medical foreign substance suction apparatus for forcibly sucking and removing foreign substances such as blood, saliva, vomit and secretions generated in the body of a patient while performing a procedure in a hospital. In general, patients with mobility problems in hospitals or homes are usually equipped with a suction unit and guardians and nurses work to remove foreign objects from the airway or surgical site.

A general suction unit is composed of a suction unit for sucking foreign matter and other dirt, a receiving unit for accommodating the foreign substances, a driving unit for applying a suction force to the suction unit, and a suction pipe for moving the dirt. However, the conventional suction machine has a lot of noise and there is room for improvement in that it requires the operation of the patient or the caregiver.

In addition, since foreign substances can occur in the sleeping area and block the airway of the patient, the nurse, caregiver and guardian must drive the suction machine from time to time. However, the conventional suction machine has discomfort because it needs to remove the foreign substances from the patient through the reaction coming from the patient and remove it from time to time regardless of the night or the day.
In this regard, Korean Patent No. 20-0454366 discloses an invention for preventing suction of skin and clothing that may occur during a suction, and Korean Patent Publication No. 10-1279451 discloses an automatic suction The present invention discloses an invention for preventing the propagation of germs and air pollution by discharging it, but does not disclose an invention for reducing noise and vibration and removing the foreign substance by artificial intelligence.

Therefore, it is necessary to reduce the noise and vibration for the health of the patient, to remove the foreign material from the patient whenever the foreign object is generated by artificial intelligence, and to improve the convenience and work efficiency of the protector or the nurse.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a suction unit for automatically detecting foreign substances in a patient by artificial intelligence and automatically sucking foreign substances from time to time.

According to an embodiment of the present invention, a suction unit includes a driving unit, an input unit, a sensor unit, a tube unit, a control unit, and a storage unit. The driving unit is disposed at a lower portion and periodically pumped. The input unit is positioned on the front surface and inputs a set value for control. The sensor unit measures a breathing state of the patient, and the tube unit is provided with a foreign substance And the control unit receives the set values and the measurement results from the input unit and the sensor unit, respectively, and controls the driving unit. The storage unit sucks and stores foreign substances and stores and supplies the saline solution.

In one embodiment, the driving unit may include a BLDC motor capable of performing suction and air injection with periodic pumping, and a driver connected to the BLDC motor at a distance to receive the control signal from the controller to control the BLDC motor .

In one embodiment, the input unit includes a device setting window in which breathing information indicating the number of respirations per minute of the user, the respiration amount indicating the amount of breathing by the user at one time and the number of breaths per hour, and the setting buttons for driving the breathing function and the suction are formed can do.

In one embodiment, the sensor unit checks the daily breathing state indicating the patient's breathing pattern and the amount of gas exhaled for a predetermined time, transmits the measurement result to the control unit, measures the mass of the patient's breathing gas and the daily breathing state And an MFM sensor for transmitting the measurement result of the daily breathing state to the control unit.

In one embodiment, the controller analyzes the daily breathing state received from the MFM sensor to determine the foreign matter generation inside the body of the patient, and controls the driving unit to suck the foreign matter, By analyzing the breathing state, it is possible to drive the simplified breathing function when it is determined that the user's breathing state is irregular and difficult.

In one embodiment, the suction unit may further include a motor cover surrounding the BLDC motor, blocking noise of the BLDC motor, and reducing vibration.

In one embodiment, the tube portion may include a first cuff, a second cuff, a first tube, a second tube, a third tube, and a fourth tube. Wherein the first cuff is formed at an upper portion and is inflated by air to expand the bronchus; the second cuff is formed at a lower portion adjacent to the first cuff, and when the first cuff contracts, The first tube is connected to the first cuff to move air, the second tube is connected to the second cuff to move air, and the third tube is directly connected to the bronchial tube Air for breathing moves, and the foreign substances in the fourth tube are moved and connected to the suction container, and the first and second cuffs can alternately expand and contract to expand the bronchus of the user.

In one embodiment, the sensor unit may further include a filter for preventing moisture from penetrating into the sensor unit and preventing dirt from entering the driving unit.

In one embodiment, the reservoir includes a suction container, and the suction container can automatically pump the foreign substance to the outside when the foreign substance is filled to 80% or more.

According to the present invention, unlike a conventional suction unit, a suction unit grasps the daily breathing state of the user through the MFM sensor, and senses the generation of foreign matter and sucks it. Therefore, the suction unit sucks the foreign substance only when the foreign material is generated in the bronchus of the user, so that the power consumption is small and the effect is great for the patient without consciousness in the absence of the caregiver.

In addition, the motor cover covers a brushless motor (BLDC motor) and covers the outside of the BLDC motor to prevent noise and vibration emitted by the BLDC motor. Suction machine with low noise and vibration can be used in various environments such as infants and patients who are sensitive to the surrounding environment, and emergency button can be used to call the protector when the suction machine is pressed at the same time.

The MASS FLOW METER (MFM sensor) directly measures the mass of the constants, which is advantageous for low-flow gas measurement and does not measure the volume or pressure of the gas. Therefore, the mass of the flowing gas is measured accurately This is possible. In addition, since a device for generating vibration is not formed in the process of measuring the mass of the gas, the convenience of the user in using the suction unit is increased.

Since the suction unit equipped with the MFM sensor includes the simple breathing function, if the user's breathing state is irregular or difficult, the lung function can be improved through the simplified breathing function and the user's life can be maintained in the case of an emergency It is effective. In addition, the function of inducing the user to gradually increase the inspiratory time can improve and train the user's lung function.

The first and second cuffs of the tube portion alternately expand and contract to minimize the inflammation or infection of the user's bronchial tube, and it is unnecessary to frequently replace the tube portion, thereby enhancing the user's convenience.

The suction unit may be equipped with a Bluetooth or Wi-Fi device. Accordingly, when the user's sudden change of the daily breathing state is changed rapidly, it is possible to operate the artificial respiration with artificial intelligence and send a warning message to a protector, a doctor or a nurse, thereby saving a user's life in an emergency.

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

1 is an exploded perspective view showing a structure of a suction unit according to an embodiment of the present invention.

1, the suction unit 10 includes a cover unit 20, a driving unit 30, a storage unit 40, a sensor unit 50, a vacuum gauge 60, a sprayer 70, an input unit 80, A filter 90, a scale 100, a tube portion 110, and a control portion 120.

The cover portion 20 includes a front cover 20a, a rear cover 20b, and a motor cover 20c. The input unit 80 is formed on the front cover 20a, and a switch for turning on the power of the suction unit 10 is provided on the front cover 20a.

The driving unit 30 includes a driver 30a, a brushless motor 30b and a solenoid valve 30c. The storage unit 40 includes a saline container 40a and a suction container 40b, and the sensor unit 50 includes a mass flow meter (MFM sensor) 50a.

The rear cover 20b is formed on a rear surface of the suction unit 10 and is coupled with the front cover 20a to protect the internal devices of the suction unit 10 and to block noise and to prevent external contaminants from entering .

The motor cover 20c is formed in a double case structure and has a sponge formed at the center thereof. The double case structure is formed to block the noise of the driving unit 30 and to reduce vibration. The motor cover 20c has the effect of lowering the stress of noise and vibration to users who always use the suction device 10 at all times.

The driver 30a controls the BLDC motor 30b by transmitting a signal received from the controller 120. [ The driver 30a is connected to the BLDC motor 30b at a distance from the BLDC motor 30b and is formed outside the motor cover 20c in order to reduce the influence of heat and noise of the BLDC motor 30b.

The BLDC motor 30b is connected to the driver 30a and pumping stably and periodically. The BLDC motor 30b is formed at the lower end of the suction unit 10 to provide power for suction of foreign substances inside the user's body and respiration of the user. The BLDC motor 30b uses a BLDC motor (BRUSHLESS DC).

Since the BLDC motor 30b can easily change the desired pressure, FLOW RATE (NL / m) and the driving period of the motor by increasing or decreasing the current, unlike the conventional AC motor, It is possible to perform suction only when foreign matter is generated rather than continuous suction. Further, since the BLDC motor 30b is strong against heat and low in noise, particularly, there is no arc generation at ON / OFF, and the motor life time is three times longer than that of a general AC motor, It is stable.

The solenoid valve 30c draws a rod moving upward and downward when the round cylindrical bar is magnetized by flowing a current into the coil by inserting a round cylindrical rod having a lower end such as soft iron into the coil. And the valve is opened as the rod which blocks the passage of the valve is raised. On the contrary, when the current is cut off to the coil, the round cylindrical bar loses magnetism and the valve is lowered while the rod is lowered.

The solenoid valve 30c is connected to the control unit 120 and receives a signal to close the solenoid valve 30c when it sucks foreign matter. Therefore, when the foreign substance is sucked in, the air containing oxygen injected to the user for breathing is prevented from being sucked back into the suction device 10 again.

The solenoid valve 30c may be connected to both the MFM sensor 50a, the saline container 40a and the suction container 40b or may be connected to the MFM sensor 50a, the saline container 40a, And may be formed of three independent valves coupled with the suction vessel 40b.

The first to third solenoid valves 30c connected to the MFM sensor 50a, the saline solution container 40a and the suction container 40b will be described for convenience of description.

The storage unit 40 includes a saline container 40a and a suction container 40b.

The saline solution container 40a is filled with saline solution and is adjusted to a proper capacity in order to secure a space for the balance 100 at the bottom. The saline solution container 40a includes a self-motor, so that the saline solution is sent before the foreign matter is sucked, thereby making the foreign matter easily sucked. The saline solution container 40a is detachable and attachable for saline replacement and cleaning.

The scale 100 and the small motor are formed under the saline solution container 40a. The balance 100 constantly measures the weight of the saline solution in the saline solution container 40a and sends a signal to the controller 120 when the weight of the saline solution is less than a predetermined weight. The control unit 120 receives the signal and indicates a saline supply signal through the input unit 80.

The saline solution container 40a is connected to the first solenoid valve 30c. Therefore, the first solenoid valve 30c is opened before the foreign object is sucked, and the saline solution of the saline container 40a is mixed with the foreign matter in the bronchus of the user to increase the fluidity of the foreign matter.

The suction container 40b is formed inside a side surface of the suction unit 10 and stores the foreign substances that are sucked. The scale 100 is formed under the suction container 40b. The suction container 40b is formed to have a proper capacity in order to secure a space for the balance 100. The suction container 40b is detachable and attachable for cleaning and cleaning of the foreign substances.

The suction container 40b is engaged with the second solenoid valve 30c. Therefore, when the saline solution in the saline solution container 40a increases the fluidity of the foreign substance, the first solenoid valve 30c is closed. The second solenoid valve 30c opens and sucks the foreign matter.

In addition, when the suction container 40b is filled with the foreign substance through the scale 100 by 80% or more, the suction pump 40b operates the self pump to discharge the foreign substances to the sewer or the toilet.

When the foreign substances are sucked in, the second solenoid valve 30c is closed and the third solenoid valve 30c connected to the MFM sensor 50a is opened.

The sensor unit 50 includes an MFM sensor 50a.

The MFM sensor 50a is formed on a side surface of the BLDC motor 30b. Since the MFM sensor 50a is small in size and light in weight, the influence of the MFM sensor 50a on the overall weight of the suction device 10 is small. The MFM sensor 50a measures the mass of the gas as a reference. The mass of the gas is the basis of all physical measurements together with units such as length, time, etc., as a measure of measurement in which units of measurement are not derived from other physical quantities. Therefore, the MFM sensor 50a directly measures the mass of the invariance, so that it is possible to grasp the accurate amount of gas flow without complicated calculation.

It is also advantageous for measuring low-flow gases and it is not possible to measure the volume or pressure of the gas, so it is possible to measure the mass of the flowing gas with an accurate value. Since the device for generating vibration is not formed in the process of measuring the mass of the gas, the convenience of the user in using the suction device 10 is increased.

The MFM sensor 50a can measure masses of various gases such as CO2, Ar, Methane, Hydrogen and Nitrogen, and can measure the mass of CO2 of a user using the suction unit 10, It is possible to grasp the state of the user by measuring complex data such as expiration, intake, lung capacity and lung function.

Therefore, the MFM sensor 50a is installed to not only suction the foreign substance but also to measure the respiratory state and the gas generated during the breathing when the user's health condition deteriorates. In addition, the MFM sensor 50a initially stores the daily breathing state of the user. The routine breathing state includes the overall state of the user's breathing state, such as air mass (breathing mass) or flow rate and breathing rate per minute that the user exhales.

The foreign matter is generated in the bronchus of the user, and the mass or flow rate of the air exhaled by the user is changed, and the MFM sensor 50a senses it. The MFM sensor 50a transmits the result of the changed breath mass or flow rate and the respiration rate per minute to the controller 120. [

The vacuum gauge 60 is formed on the front surface of the front cover 20a to indicate the suction pressure of the suction unit 10. If the suction pressure of the suction device 10 becomes abnormally high, the vacuum gauge 60 may be formed on the entire surface of the user's respiratory apparatus, thereby checking the normal pressure. The vacuum gauge 60 will use an analog vacuum gauge that is safe and error-free.

The atomizer (70) is formed outside the side surface of the suction unit (10). The sprayer 70 can be used to stabilize the breathing state of the user when the user's breathing is difficult.

The input unit 80 includes a touch panel or a general panel, and a plurality of buttons may be formed at a position where the input unit 80 is formed, so that the respiration rate can be selected according to the age. Since the input unit 80 is formed of a touch panel, the user can intuitively select the input unit 80, so that there is no need to worry about a complicated description and an operation method.

The filter (90) is formed on the entire surface of the saline solution container (40a) to purify the air entering the user's body.

The scales 100 are formed under the saline container 40a and the suction container 40b to measure the amount of foreign substances and saline contained therein. The measurement result of the balance 100 is transmitted to the controller 120 when the amount of the foreign substances and the saline reaches a certain level.

The tube unit 110 is connected to the outside of the suction unit 10 to suck foreign matter generated inside the user's bronchial tube. When the foreign substances exceed a predetermined weight, the balance 100 transmits a weight overrun signal to the controller 120. [

When the amount of the saline solution is reduced to less than a predetermined weight, the scale 100 transmits a signal below the weight to the controller 120. The controller 120 emits a sound or an alarm for filling the saline through the input unit 80.

The controller 120 is formed on the driver 30a. The control unit 120 analyzes the result of the changed daily breathing state from the MFM sensor 50a and sends a signal for driving the BLDC motor 30b to the driver 30a. The BLDC motor 30b starts pumping through a signal from the driver 30a and the tube unit 110 sucks foreign substances generated in the bronchus of the user.

When the over-weight signal and the under-weight signal are received, the control unit 120 displays a sound or an alarm through the input unit 80. FIG.

When the amount of foreign matter and saline in the storage unit 40 exceeds a predetermined level, the balance unit 100 sends the over-weight signal and the under-weight signal to the control unit 120, respectively.

2 is a perspective view showing a structure of a tube portion included in the suction unit of FIG.

Referring to FIG. 2, the tube 110 includes a first cuff 110a, a second cuff 110b, a first tube 110c, a second tube 110d, a third tube 110e, And a tube 110f.

The tube portion 110 is connected to the suction unit 10 and includes the first and second cuffs 110a and 110b. The tube portion 110 is a tube for tracheostomy and passes through the user's neck and is located inside the bronchus of the user. The first and second cuffs 110a and 110b of the tube 110 swell in the bronchus of the user with a syringe or an air injection device to expand the inside of the bronchial tube.

The first and second cuffs 110a and 110b swell in the bronchus of the user one after another over a predetermined period of time. The first and second cuffs 110a and 110b are swollen and contracted in order from the upper and lower positions. When the first and second cuffs 110a and 110b are formed by swelling in the bronchi for a long time, Or infection may occur. Accordingly, the user can inflate the first and second cuffs 110a and 110b in order to prevent the inflammation or infection.

The first tube 110c and the second tube 110d may be connected to the first and second cuffs 110a and 110b in order to inflate the first and second cuffs 110a and 110b, Respectively.

After a predetermined inflation time of the first cuff 110a has elapsed, air is extracted using the first tube 110c and the second cuff 110b is inflated using the second tube 110d. The above operation is repeated according to a certain expansion time, thereby lowering the possibility of inflammation or infection of the bronchus of the user. Therefore, the user does not need to frequently replace the tube portion 110, and convenience is improved.

The third tube 110e is a space used by the liver for artificial respiration when the user's breathing state is difficult.

The tube unit 110 connects an elongated T tube to the T tube in order to reduce the burden on the user's neck and connects the tubes of the suction unit 10 to the T tube. The fourth tube 110f and the third tube 110e formed on the outside of the suction unit 10 are formed in the T tube to reach the bronchus of the user.

The MFM sensor 50a measures the daily breathing state such as respiration rate per minute of the user, the mass or flow rate of the exhalation gas, and transmits the measured breathing state to the controller 120, so that the controller 120 grasps the state of the patient. If it is determined that there is a problem in the breathing state of the patient by analyzing the routine breathing state, the controller 120 drives the BLDC motor 30b to supply oxygen through the third tube 110e.

Also, the controller 120 of FIG. 1 may include a Bluetooth or Wi-Fi device to operate the simple artificial respiration by artificial intelligence and send a warning message to a protector, a doctor, or a nurse when the user's daily respiratory state changes abruptly Therefore, there is a great effect that the life of the user can be saved in the emergency.

Therefore, the suction device 10 can perform artificial respiration through the third tube 110e.

The second tube 110d is a passage for sucking the foreign substances generated inside the bronchus of the user. The foreign substances are moved to the suction container 40b through the second tube 110d.

The saline solution in the saline solution container 40a is sprayed on the foreign substances generated in the body, such as saliva, sputum, and solid foreign substances, generated in the bronchus of the user through the second tube 110d. If the saline solution is sprayed on the foreign substances, the foreign substances increase in fluidity. Therefore, the foreign substances are easily sucked into the suction force through the second tube 110d.

Therefore, before the suction unit 10 is sucked, the saline solution is first mixed with the foreign substance through the fourth tube 110f to increase fluidity of the foreign substance, and the BLDC motor 30b is driven to suck the foreign matter.

Fig. 3 is an exploded perspective view showing the structure seen from the other direction of the suction unit of Fig. 1;

The suction unit 10 further includes a USB terminal 140 and a power switch 130 on the rear surface.

The USB terminal 140 may be connected to a notebook PC or a desktop PC to receive the daily breathing status of the user in real time, store and analyze the statistics data. By using the above statistics, it is possible to grasp the daily breathing state peculiar to the user. The daily breathing state of only the user is stored in the notebook or the desktop PC, and more accurate analysis becomes possible.

The power switch 130 is formed below the USB terminal 140 to turn off the power of the suction unit 10 and turn on the power.

4 is an image showing a driving screen on the input unit of the suction unit of FIG.

The suction unit 10 includes a function of a nebulizer that can improve the lung function to improve the respiration function of the user. The input unit 80 operates in a touch input manner and can perform the function of the nebulizer intuitively.

The sprayer 70 is used for improving the respiration function and the sprayer 70 is detached and connected to the third tube 110e. The nebulizer function includes a function of gradually increasing the user's breath and inspiration time in addition to bronchodilation or bronchial therapy and pulmonary therapy.

Therefore, with the nebulizer function, the user can recover irregular respiration rate per minute and abnormally high respiration rate per minute, and has an effect of improving lung capacity.

Referring to FIG. 4, the input unit 80 includes respiration information 81 and a device setting window 82. The respiratory information 81 includes respiratory rate 81a per minute, respiratory rate 81b per hour and respiratory rate per hour 81c. The device setting window 82 includes a room temperature 82a, a respiratory rate 82b, A control button 82c, a driving time 82d, a pressure button 82e, an inspiration time 82f, an expiration time 82g, a start button 82h and a simple respiration button 82i.

The respiration rate per minute 81a represents the total amount of expiration and inspiration per minute, and the one-time respiration rate 81b represents the amount of gas exhaled or inhaled during exhalation or inspiration. The minute respiration rate 81a and the first respiration rate 81b are values that can check the current status of the user in a short time.

The number of breaths per hour (81c) represents the total of breath and inspiration per hour, and is a value that can check whether the condition of the patient, which can not be frequently checked, is improving.

The room temperature 82a indicates the room temperature of the place where the user uses the suction device 10 and can check the temperature which is an important controlling element for improving the condition of the user who has a weak operation or bronchial.

The respiration number step 82b is formed of a plurality of buttons and selects the respiration number step 82b according to the user's respiratory rate 81a per minute. If one of the respiration number steps 82b is selected, the air is injected a number of times corresponding to half of the respiratory rate 81a per minute of the user. For example, if the user selects the respiration number step 82b with 10 breaths per minute, the respiratory rate 81a per minute becomes 10 times and the injection is performed 5 times for 1 minute. Therefore, it is injected 5 times in accordance with the expiration time for 6 seconds at a time, and the user is induced to drink for 6 seconds in which air is injected for 1 minute.

Accordingly, the user is guided to drink while the air is being injected by the function of the suction unit 10, and the breathing time is gradually increased every time the breathing number step 82b is increased, thereby improving the volume of the lungs, irregularly and abnormally It is possible to recover normal respiration rate per minute.

The number of buttons of the respiration number step 82b is not limited to three but may be formed of a plurality of buttons.

The control button 82c is a button for controlling the set values, pressure, time, and the like, and the start button 82h is a button for starting the operation of the settler 10 having been set.

The drive time 82d indicates the time when the user uses the suction unit 10. The user enters the time to use the suction unit 10 in a divided manner.

The pressure button 82e indicates the pressure of the air sprayed to the respirator of the user, and the user can set the pressure within a certain range.

The intake time 82f represents the time taken by the user, that is, the intake time, and can be set in units of seconds. The intake time 82f can be set from 1 second to 10 seconds.

The expiration time 82g indicates the time that the user exits, that is, the expiration time, and can be set in units of seconds. The exhalation time 82g can be set from 1 second to 10 seconds.

The start button 82h is a button for starting the operation of the suction unit 10 after the setting of the device setting window 82 is completed.

The simplified breathing button 82i is a button that is used manually to improve the breathing state of the user or when the breathing state of the user is irregular and difficult. However, the MFM sensor 50a of the suction device 10 measures the breathing state of the user at all times and starts breathing artificially.

Therefore, the simplified breathing button 82i is used to increase the inspiration time of the user and to improve the lung function or to use in an emergency.

[Table 1]

[Table 2]

Table 1 shows the respiration rate steps 82b divided by age and the respiration rate per minute 81a, and Table 2 shows the injection time ratio and pressure according to the flow rate increasing step.

The values in Tables 1 and 2 are user-adjustable and will use the above values for ease of explanation.

Referring to Table 1, the respiration number step 82b is divided into the age groups and represents the respiration rate 81a per minute according to each age group.

Referring to Table 2, the flow rate increasing step is capable of a plurality of steps, and a different time interval is set between the flow rate increasing steps.

The respiration rate per minute 81a represents the sum total of the intake air and the exhalation within one minute, and the flow rate increasing step refers to a step in which the injection time ratio exceeds the next rate.

The injection time ratio represents a ratio of time during which the sprayer 70 is sprayed during intake. For example, when the user selects Adult in the respiration number step 82b and sets the time of the flow rate increase step to 1 minute, if the respiratory rate 81a per minute is 10 times, the number of times of intake is 5 times to be.

Therefore, the time of one inspiration is 6 seconds. At this time, the flow rate increasing step is started in step 1, and it takes one minute to go from step 1 to step 2. Wherein the injection time ratio in the first step is one.

If the injection time ratio is 1, the sprayer 70 is sprayed for 6 seconds of the intake time. If the flow advances to the second step after one minute, the injection time ratio is changed to 1.1, and the sprayer 70 is sprayed for 6.6 seconds. After one minute, the injection time ratio is changed to 1.2, and the intake time, that is, the injection time of the air, is increased to 7.2 seconds.

In this way, the injection time of the air increases in proportion to the injection time ratio according to the injection time ratio, and the user is induced to breathe by the injection time of the air extended by the use of the suction device 10 for several hours or several days Naturally, the time of inspiration is increased.

The function of inducing the intake time to be long can be applied not only to the suction device 10 but also to various kinds of suction devices.

The present invention can be applied not only to the suction device 10 but also to products for increasing lung capacity, and can be used for lung cancer patients, athletes, rhinitis patients, users who want to improve their abdominal or abdominal breathing, depressed patients and psychiatric patients Do.

In patients with lung cancer, some of the lungs that are normally breathable can be improved and the blood circulation can be facilitated, which can help in the treatment of lung cancer.

The athlete has the advantage of exercising the lung function by exercising in the daytime and training the lung function through the function of guiding the suction device 10 or the inspiratory time longer during sleep.

In patients with rhinitis, the function of guiding the inspiratory time is long, and the immunity is enhanced, and the blood circulation of the whole body and the nose is smoothly performed, so that there is an effect of self treatment for rhinitis.

For users who practice danseon or abdominal respiration, the function of inducing the inspiratory time is increased to improve the pulmonary function and induce abdominal breathing during the sleep, thereby increasing the effect of the abdominal breathing and abdominal breathing.

The function of guiding the inspiratory time to the students and the workers who need the concentration of mind also has a good effect on the health as well as the concentration on the study by improving the function of the lung and smoothing the blood circulation.

In psychiatric patients, stable breathing is induced to improve blood circulation in the brain and to create a positive body condition. Thus, physical stability induces mental stability and thus reduces anxiety and depression in psychiatric patients.

5 is a block diagram showing a driving method of the suction unit of FIG.

The power is connected to the controller and the driver to supply power (step S101)

The MFM sensor sends a measurement result to the control unit when the mass or flow rate of the user's breathing gas and the daily respiration state change (Step S102).

The controller receives and analyzes the measurement result of the MFM sensor and transmits a driving signal to the driver when it is determined that the foreign object is generated after the normal breathing state is exited (step S103).

The driver receives a signal from the control unit and sends a signal to the BLDC motor (step S104).

The BLDC motor is driven by receiving a signal from the driver. At this time, the outside air flows through the moisture filter toward the BLDC motor (step S105).

The first solenoid valve connected to the saline solution container is opened to increase the fluidity of the foreign matter before the foreign matter is sucked (step S106).

The small motor connected to the saline container is driven to suck saline in the saline container (step S107).

The saline solution in the saline solution container flows through the first solenoid valve to the user's bronchus through the fourth tube to increase fluidity of the foreign matter. The balance below the saline vessel sends a signal to the control unit when the saline solution in the saline vessel is insufficient (Step S108).

When the first solenoid valve is closed, the third solenoid valve connected to the third tube is also closed (step S109).

After the fluidity of the foreign matter is increased, a second solenoid valve connected to the BLDC motor is opened through the fourth tube (step S110).

The second solenoid valve is opened and the foreign substances whose fluidity is increased by the suction container pass through the fourth tube and the second solenoid valve and are sucked at a certain pressure. Then, the weight of the foreign matter is measured at all times through a scale formed in the bottom of the suction vessel, and a signal is sent to the control unit if it is more than a predetermined amount (step S111).

When the foreign matter is sucked at a certain pressure, the second solenoid valve is closed, the third solenoid valve is opened, and the respiration state is maintained. The MFM sensor measures the daily breathing state of the user at all times (step S112).

According to the embodiments of the present invention as described above, the suction unit 10 senses the daily breathing state of the user through the MFM sensor 50a, senses the generation of foreign matter, and sucks the suctioned air, unlike the conventional suction unit. Therefore, the suction unit 10 sucks the foreign substance only when the foreign material is generated in the bronchus of the user, so that the power consumption is small and the effect is great for the patient who is not conscious of the absence of the caregiver.

The motor cover 20c covers the BLDC motor 30b and covers the outside of the BLDC motor 30b to prevent noise and vibration emitted from the BLDC motor 30b. The suction device 10 having little noise and vibration has an advantage that it can be used in various environments such as infants and patients sensitive to the surrounding environment.

The BLDC motor 30b can easily change the pressure desired by the user, the flow rate (NL / m), and the driving period of the motor by increasing or decreasing the current, unlike the conventional AC motor. It is possible to inject air only to the intake air of the user rather than the air spray which follows the breath. And it is strong and stable against heat, less noise, less arcing at ON / OFF, longer motor life time than general AC motor, and smaller size than performance AC motor.

When the user uses the suction device 10 over a period of several days, the suction time becomes longer, so that the user has natural abdominal breathing or long intake and breathing habits. And the increased intake time can provide a natural effect of improving blood circulation and improving lung capacity. In addition, post-operative aftereffects of the lungs in patients with poor function and infants can induce natural breathing.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the following claims. It can be understood that it is possible.

The suction unit, which senses the generation of foreign matter by the sensor according to the present invention and thereby assists the suction automatically, has industrial applicability that can be used in most hospitals and homes for patients who need the help of a guardian.
