3 is a flowchart illustrating a method of controlling a medical suction machine according to an embodiment of the present invention. Hereinafter, a control method of the medical suction machine 100 according to an exemplary embodiment of the present invention will be described with reference to FIGS. 1 to 3.

First, as shown in FIG. 2, the user selects a'suction repetition' button displayed on the input unit 180 as a touch-type display panel, thereby setting the number of repetitions of suction when the foreign body suction in the bronchus is executed by the controller 135. (S310).

Thereafter, the control unit 135 of the medical suction apparatus 100 receives the patient's stethoscope sound information received from the stethoscope microphone 145, the pulse rate information of the patient received from the pulse measurement unit 155, and the oxygen saturation measurement unit 165. When it is determined that it is necessary to remove foreign substances such as sputum from the patient's bronchi based on the patient condition information including the patient's oxygen saturation information, the controller 135 starts a foreign substance suction in the patient's bronchi Determine it (S320).

The control unit 135 that determines the initiation of the foreign substance suction, first controls the saline supply unit 160, so that a small amount (for example, about 5 cc) of saline solution is introduced into the patient's bronchus through the tube installed inside the patient's bronchus. To be supplied to (S330).

On the other hand, the saline supplied in step S330 described above is supplied to the foreign substance in a hardened state inside the patient's bronchi to soften the foreign substance, and the foreign substance softened by the saline can be more easily inhaled through the catheter 10 afterwards. There will be.

On the other hand, if the user is set to supply oxygen to the patient prior to the execution of the foreign substance suction by entering the'external oxygen' button in FIG. 2 before step S310 described above, the controller 135 after the execution of step S330 described above By controlling the oxygen supply unit 150, a high concentration of oxygen is supplied to the patient through a tube installed inside the patient's bronchi (S340).

As described above, in the present invention, by supplying a high concentration of oxygen to the patient before the foreign body suction is performed inside the bronchi, it is possible to prevent the risk of oxygen shortage to the patient due to the foreign body suction.

After the execution of the above-described step S340, the control unit 135 transmits an operation start command to the driving device 140 and the first suction pump 110, and accordingly, the catheter 10 enters the respiratory system and the catheter 10 Inhalation of foreign substances through is performed (S350).

FIG. 4 is a flowchart illustrating a detailed execution process of a foreign substance suction in the bronchus in FIG. 3. Hereinafter, a detailed execution process of a foreign substance suction in the bronchus will be described with reference to FIG. 4.

When the foreign body suction in the bronchus is initiated by the control unit 135 transmitting an operation start command to the driving device 140 and the first suction pump 110 (S351), the control unit 135 is located inside the catheter 10. Whether the state in which the measured pressure value in the pressure sensor for measuring the actual suction pressure value exceeds a predetermined reference pressure value (for example, 500 mmHg) is continued for a predetermined reference time (for example, 2 seconds) or more. It is judged (S353).

When the state in which the measured pressure value in the pressure sensor exceeds a predetermined reference pressure value continues for a predetermined reference time or longer, the control unit 135 determines that the inside of the catheter 10 is blocked by a foreign object, and the driving device 140 ) And stop driving of the first suction pump 110 (S355), and output a voice message for catheter replacement guidance, such as'Please use after replacing the catheter' through the output unit 170 (S357).

On the other hand, the foreign substance suction in the bronchus in step S350 described above is executed for a predetermined time (for example, 10 seconds), the control unit 135 ends the execution of the foreign substance suction as the predetermined time elapses, the oxygen supply unit By controlling the 150, a high concentration of oxygen is supplied to the patient through a tube installed inside the patient's bronchi.

As described above, in the present invention, by supplying a high concentration of oxygen to the patient after the foreign body suction is performed inside the bronchi, it is possible to prevent the risk of oxygen shortage to the patient due to the foreign body suction.

On the other hand, after completing the foreign substance suction, the controller 135 executes a washing process of the catheter 10 through saline (S370).

5 is a flowchart illustrating a detailed execution process of catheter washing in FIG. 3. Hereinafter, a detailed execution process of catheter washing will be described with reference to FIG. 5.

First, the control unit 135 controls the saline supply unit 160 to supply the saline solution to the catheter 10 and the saline solution to the inside of the tube into which the catheter 10 is inserted. A saline solution is supplied to the outside of the catheter 10 (S371).

Then, the controller 135 sucks the saline supplied into the catheter 10 by driving the first suction pump 110 connected to the catheter 10 (S373), and then the catheter 10 is internal The saline solution supplied to the outside of the catheter 10 is sucked by driving the second suction pump 120 connected to the tube installed in the body (S375).

As described above, in the present invention, the controller 135 does not drive the first suction pump 110 and the second suction pump 120 at the same time, and directly to the catheter 10 without driving the second suction pump 120. It is possible to increase the washing efficiency through saline inside the catheter 10 by independently driving only the first suction pump 110 connected.

When the cleaning of the catheter 10 in step S370 is completed, the controller 135 determines whether the cumulative number of executions of foreign substance suction in the bronchus is the same as the number of repetition of suction in step S310 described above (S380). ).

If the cumulative number of executions of foreign substance suction in the bronchus is not the same as the number of times of setting the suction repetition in step S310 described above, the controller 135 repeats the execution of steps S330 to S370 described above.

On the other hand, when the cumulative number of executions of the foreign substance suction in the bronchus is the same as the number of times of setting the suction repetition in step S310 described above, the controller 135 ends the repetition of the foreign substance suction in the bronchus and the third suction pump 130 Suction is performed for saliva such as saliva accumulated in the patient's mouth by driving (S390).

FIG. 6 is a process flow diagram illustrating a detailed execution process of the determination to start suction in FIG. 3. Hereinafter, with reference to FIGS. 1 and 6, a detailed execution process of determining the start of suction in the artificial intelligent medical suction device 100 according to the present invention will be described.

First, the sensor unit 190 includes a first mass flow meter sensor and a second mass flow meter sensor, and the first mass flow meter sensor measures a patient's exhalation volume from an exhalation outlet of a breathing mask worn by a patient. 2 The mass flow sensor measures the patient's inspiratory respiratory volume from the intake inlet of the breathing mask (S321).

On the other hand, the controller 135 alternately receives the patient's exhalation volume measurement from the first mass flow meter sensor and the patient's inhalation volume measurement from the second mass flow meter sensor, and as a result, the controller 135 breaths cycles of the patient It is possible to secure sugar volume information in real time.

In addition, the controller 135 calculates the interval between the time at which the exhalation respiratory volume measurement value was received from the first mass flow meter sensor and the time at which the next exhalation respiratory volume measurement value was received, thereby determining the period of breathing (inhalation/exhalation) of the patient. It can be measured (S322).

As described above, the controller 135 accumulates and stores the patient's respiratory volume information and the respiratory cycle in real time, and the controller 135 calculates and stores the cumulative average value of the patient's respiratory volume and calculates the cumulative average value of the patient's respiratory cycle, and To save.

On the other hand, the control unit 135 determines whether the patient's respiratory rate per breathing cycle received in real time from the sensor unit 190 from the sensor unit 190 is less than the cumulative average value (reference respiratory volume) of the patient's respiratory volume (S323). .

In general, when foreign substances such as sputum accumulate in the respiratory tract for a certain amount or more, the patient's breathing becomes shorter, and as a result, the breathing cycle is shortened and the respiratory volume per breathing cycle is reduced.

Accordingly, when it is determined that the respiratory volume per patient's breathing cycle is less than the cumulative average value (reference breathing volume) of the patient's breathing volume, the controller 135 determines that sputum removal is necessary and initiates foreign body suction in the bronchus. Decide (S329).

On the other hand, in step S323 described above, when the controller 135 determines that the respiratory volume per patient's breathing cycle is equal to or greater than the cumulative average value (reference respiratory volume) of the patient's respiratory volume, the controller 135 as the next step is the current breathing of the patient It is determined whether the cycle is smaller than the cumulative average value of the breathing cycle (reference cycle) (S324).

As a result, if it is determined that the patient's current measured breathing cycle is smaller than the cumulative average value of the breathing cycle (reference cycle), even if there is no abnormality in the patient's breathing volume, it is determined that the breathing is shortened by sputum, etc. Initiation of a foreign substance suction in the inside is determined (S329).

Meanwhile, in step S324 described above, when the controller 135 determines that the patient's currently measured breathing cycle is not less than the cumulative average value (reference cycle) of the breathing cycle, the controller 135 analyzes the waveform of the patient's stethoscope sound. Then, it is determined whether the maximum amplitude (Amplitude) of the analyzed waveform exceeds a predetermined reference amplitude value (S326).

On the other hand, in the practice of the present invention, the control unit 135 is an average value obtained by accumulating the maximum amplitude (Amplitude) of a waveform that converts a waveform of auscultation sound measured from a patient who has no breathing disorder due to sputum into a frequency domain. Can be set as the reference amplitude value.

When the maximum amplitude (Amplitude) of the waveform analyzed by the control unit 135 for the stethoscope sound received from the stethoscope microphone 145 exceeds a predetermined reference amplitude value, the control unit 135 controls the sound of the patient's breath by sputum or the like. Is determined to be in a rough state, and the initiation of a foreign substance suction in the bronchus is determined (S329).

On the other hand, in step S326 described above, when the controller 135 determines that the maximum amplitude (Amplitude) of the waveform analyzed for the stethoscope sound received from the stethoscope microphone 145 does not exceed a predetermined reference amplitude value, the controller ( 135) determines whether the patient's current pulse rate exceeds the reference pulse rate (S327).

Specifically, the normal control unit 135 receives the patient's pulse rate in real time from the pulse measurement unit 155 installed on the patient's wrist, and sets the average value of the accumulated received pulse rate as a reference pulse rate.

On the other hand, when the pulse rate received by the control unit 135 from the pulse measurement unit 155 exceeds the reference pulse rate, the control unit 135 makes it difficult for the unconscious patient to breathe due to foreign substances in the respiratory system such as sputum. As a result, it is determined that the pulse rate of the patient is increased and the initiation of a foreign substance suction in the bronchus is determined (S329).

On the other hand, in step S327 described above, when the control unit 135 determines that the pulse rate received from the pulse measurement unit 155 does not exceed the reference pulse rate, the control unit 135 displays the oxygen saturation level currently measured by the patient in a normal state. It is determined whether it is less than the reference oxygen saturation, which is a value corresponding to about 80% of the oxygen saturation (S328).

On the other hand, when the control unit 135 determines that the current oxygen saturation of the patient received from the oxygen saturation measurement unit 165 is less than the reference oxygen saturation, the control unit 135 does not allow the patient to be aware of it, such as foreign substances in the respiratory system such as sputum. As a result of difficulty in breathing, it is determined that the patient's oxygen saturation has fallen, and the initiation of a foreign body suction in the bronchus is determined (S329).

On the other hand, in the case where it is determined that foreign substances such as sputum are present in the respiratory tract of the patient by the above-described method and entering the respiratory tract of the catheter 10 and driving of the first suction pump 110 is started, rapid removal of the foreign substances If the driving time of the first suction pump 110 is too long due to the failure, or when the oxygen saturation of the patient falls below a predetermined reference value (for example, 92%), the operation of the first suction pump 110 is performed. It is necessary to prevent dyspnea or hypoxemia in the patient by discontinuing.

Accordingly, the present inventor proposes a control method of the artificial intelligent medical suction machine 100 to control the operation of the first suction pump 110 based on the driving time information of the first suction pump 110 and the oxygen saturation information of the patient. Became.

7 is a flowchart illustrating a process of executing a control method of an artificial intelligent medical suction machine according to another embodiment of the present invention. Hereinafter, an execution process of a control method of an artificial intelligent medical suction device 100 according to another embodiment of the present invention will be described with reference to FIGS. 1 and 7.

First, the controller 135, which determines the entry of the catheter 10 into the respiratory system, sets the suction pressure of the first suction pump 110 to be a predetermined reference suction pressure (S410), and the first suction pump 110 The driving device 140 is controlled such that the catheter 10 is moved forward at the same time as the driving of the vehicle is started (S420).

On the other hand, the control unit 135 counts the continuous driving time of the first suction pump 110 from the time when the driving of the first suction pump 110 is started (S430). If the driving time T of the first suction pump 110 counted by the controller 135 is determined to be equal to or greater than a predetermined reference time value (for example, 10 sec) (S440), the controller 135 By forcibly ending the driving of the first suction pump 110 (S470), and controlling the driving device 140 so that the catheter 10 moves backward (S480), the first suction pump 110 for a long time is driven. This prevents the patient from having difficulty breathing.

On the other hand, the reference time value in step S440 described above is a value randomly input by the user, and a guardian such as a doctor takes into account the health of the patient through the input unit 180 provided in the artificial intelligent medical suction device 100. It would be desirable to be able to individually set the reference time value.

On the other hand, in step S440, even if the driving time T of the first suction pump 110 counted by the controller 135 is less than a predetermined reference time value (for example, 10 sec), the controller 135 Determines whether the oxygen saturation measurement value of the patient received from the oxygen saturation measurement unit 165 is equal to or less than a predetermined reference value (for example, 92%) (S460).

As a result, when it is determined that the patient's oxygen saturation measurement value is less than or equal to a predetermined reference value (for example, 92%), the control unit 135 alarms through the output unit 170 provided in the artificial intelligent medical suction device 100. By outputting a signal, the medical staff is informed that the patient is at risk of hypoxemia (S460).

On the other hand, the reference value in step S460 is a value input to the control unit 135, and a guardian such as a doctor can individually set the reference value through the input unit of the artificial intelligent medical suction device 100 in consideration of the patient's health condition. Would be desirable.

After generating the alarm signal as described above, the controller 135 forcibly terminates the driving of the first suction pump 110 (S470), and controls the driving device 140 so that the catheter 10 moves backward (S640). Hypoxemia prevents the patient from becoming an emergency.
