First, the suction pump 210 is installed at one end of the catheter 100, the suction pressure in the catheter 100 so that foreign matter such as sputum is sucked through the other end of the catheter 100 inserted into the patient's respirator Generate.

The sensor unit 220 includes a mass flow meter (MFM) sensor that measures the mass of the intake gas and the exhalation gas of the patient, respectively, and measures the mass of the intake gas and the exhalation gas of the patient, respectively. The function transmits the result to the controller 270.

Specifically, the sensor unit 220 includes a first mass flowmeter sensor and a second mass flowmeter sensor, the first mass flowmeter sensor measures the exhalation volume of the patient from the exhalation outlet of the breathing mask worn by the patient, The second mass flow meter sensor measures the inspiratory breathing volume of the patient from the intake inlet of the breathing mask.

2 is a flowchart illustrating a procedure for setting individual reference values for each patient for executing a control method of an artificial intelligent medical suction device according to an embodiment of the present invention. Hereinafter, referring to FIGS. 1 and 2, an individual reference value setting process for each patient for executing the control method of the artificial intelligent medical suction device according to an embodiment of the present invention will be described.

First, the controller 270 of the artificial intelligent medical suction device 200 measures a plurality of patient state information including breathing information of a patient in a normal state (a state in which sputum removal is not required) (S310). The cumulative average value of the state information values is calculated.

Hereinafter, the process of calculating the cumulative average value for each state information by the controller 270 will be described.

Cumulative mean value of breathing volume, cumulative mean value of breathing cycle (breathing)

The controller 270 of the artificial intelligent medical suction device 200 alternately receives the patient's exhalation volume measurement value from the first mass flow meter sensor and the patient's inhalation volume measurement value from the second mass flow meter sensor, and as a result, the control unit 270. ) Can be obtained in real time to the patient's respiratory volume information per cycle.

In addition, the controller 270 calculates the interval between the time when the exhalation volume measurement value is received from the first mass flow meter sensor and the time when the next exhalation volume measurement value is received, and calculates the breathing (inhalation / exhalation) cycle of the patient. You can measure it.

As described above, the controller 270 accumulates and stores the patient's respiratory volume information and respiratory cycle information in real time, and the controller 270 calculates and stores the cumulative average value of the patient's respiratory volume, and also stores the cumulative average value of the patient's respiratory cycle. Calculate and store.

- Stethoscope  Cumulative Average Value of Waveform Size

In addition, the control unit 270 receives in real time a stethoscope sound (or breath) from the patient's chest measured from the stethoscope microphone 240, and performs the waveform analysis as shown in FIG. FIG. 3 is a diagram illustrating a waveform of a stethoscope sound measured in a state in which a patient does not have a breathing disorder due to sputum and the like into a frequency domain.

The controller 270 calculates and stores an average value obtained by accumulating the maximum amplitude of the analyzed waveform for the stethoscope sound received in real time.

Cumulative Average Value of Pulse Rate

The controller 270 receives the pulse rate of the patient in real time from the pulse measuring unit 260 installed on the wrist of the patient, and calculates and stores a cumulative average value of the cumulatively received pulse rates.

-Oxygen Saturation  Cumulative Average

The controller 270 calculates and stores a cumulative average value of the oxygen saturation values received from the oxygen saturation measuring unit.

Meanwhile, while the cumulative average value for each state information is continuously calculated and stored as described above, the manager of the medical suction device 200 such as a caregiver or a nurse who cares for the patient may have a state of breathing, breathing, or facial expression of the patient (or the patient). Sputum removal request) is directly monitored, and when it is determined that sputum removal is required, the sputum removal is performed by driving the suction device 200 by manual operation through an operation input panel (not shown) of the suction device 200. (S330).

In addition, the controller 270 calculates and stores the patient condition information measured at the time when the administrator inputs the operation command of the suction device 200 through the input panel for manual operation (that is, the time required for removing sputum) and the stored average value. Compare with each other.

Specifically, the control unit 270 compares the respiratory volume measured at the time point (needs to remove sputum) with the cumulative average value of the pre-stored respiratory volume, and compares the respiratory cycle measured at that time point with the cumulative average value of the pre-stored breathing cycle, Compares the auscultation waveform size measured at that time with the cumulative average value of the pre-stored auscultation waveform size, compares the pulse rate measured at that time with the cumulative average value of the pre-stored pulse rate, and compares the oxygen saturation measured at that time Compare with the cumulative mean value of oxygen saturation.

On the other hand, the controller 270 compares the state information in which a deviation of a predetermined rate (for example, 10%) or more is compared with the previously stored cumulative average value among the plurality of patient state information measured at the time of need for sputum removal in Table 1 below. Extract and store as shown (S350).

Status information Deviation Rate from Cumulative Average Adoption as an anomaly indicator Respiratory volume 15% O Breathing cycle 17% O Auscultation Waveform Magnitude 23% O Pulse rate 5% X Oxygen saturation 3% X

In the present invention, as shown in Table 1, the deviation of the predetermined state (for example, 10%) or more at a time point when the administrator executes the suction (ie, when the sputum removal is required) by directly monitoring a specific patient among the plurality of state information. Adopted status information as an 'abnoraml indicator', an indicator that actively indicates the patient's own condition (a condition that requires sputum removal) by significantly changing its value due to sputum occurrence in the patient. .

In addition, the control unit 270 is a value indicating that the patient is in the sputum removal request state (ie, abnormal state) measured values measured at the time of manual suction execution by the administrator with respect to the state information adopted as the abnormality indicator. Set and store as a reference value (S370).

That is, in the present invention, the individual reference value for each patient is selected as the operation reference value of the suction device 200 in consideration of the unique body response characteristics for each patient that appears when the sputum removal is required, and the patient corresponds to the reference value individually set for each patient. By determining when the state information of the proximity to the point of time that the driving of the suction device 200 for the patient, it becomes possible to tailor the nursing considering the physical response characteristics for each patient.

On the other hand, the respiratory volume, respiratory cycle, auscultation waveform size, pulse rate, oxygen saturation in Table 1 may all be abnormal indicators depending on the characteristics of each patient, the specific reasons are as follows.

Typically, when foreign substances such as phlegm accumulate in the respirator, the patient's breathing becomes poor, and as a result, the breathing cycle is shortened and the amount of breathing per breathing cycle is reduced.

In addition, when the patient's breath becomes rough due to sputum or the like, the waveform size of the stethoscope sound generally increases.

In addition, the unconscious patient is difficult to breathe due to the foreign body of the respiratory organs, such as phlegm, the pulse rate of the patient is increased, oxygen saturation is lowered.

3 is a flowchart illustrating an execution process of a control method of an artificial intelligent medical suction device according to an embodiment of the present invention. Meanwhile, FIG. 3 illustrates a case in which a respiratory rate, a respiratory cycle, auscultation waveform size, a pulse rate, and an oxygen saturation are all taken as 'abnormal indicators' among state information of a specific patient and set as reference values.

Hereinafter, referring to FIGS. 1 and 3, an execution process of a control method of an artificial intelligent medical suction device according to an embodiment of the present invention will be described.

First, the control unit 270 is a respiratory volume of the patient received in real time from the sensor unit 220, the reference breathing volume and a predetermined error range (for example, an operation reference value preset in step S370 for the patient). 5%) or not (S410).

As a result, when it is determined that the current breathing volume of the patient is within the reference breathing volume and the error range, the controller 270 determines that the sputum of the patient needs to be removed, and the suction pump 210 and the driving unit 230 are provided. The operation start command is transmitted, and thus the entry of the catheter 100 into the respirator is started (S490).

If, in step S410 described above, if it is determined that the patient's breathing volume is out of the reference breathing volume and the error range, the control unit 270 is the next step, and the current breathing cycle of the patient patient is preset in step S370. It is determined whether the reference period, which is a reference value, is within a predetermined error range (for example, 5%) (S430).

As a result, when it is determined that the current breathing cycle of the patient is within the reference breathing cycle and the error range, the controller 270 determines that the sputum of the patient needs to be removed and the suction pump 210 and the driving unit 230 In operation S490, the command to start operation is transmitted to the respirator of the catheter 100.

If it is determined in step S430 that the patient's breathing cycle is out of the reference breathing cycle and the error range, the control unit 270 is the next step, where the current auscultation waveform size of the patient is described above in step S370. In operation S450, it is determined whether the reference waveform size, which is a preset operation reference value, and a predetermined error range (for example, 5%) are present.

As a result, when it is determined that the current auscultation sound waveform size of the patient is within the reference waveform size and the error range, the controller 270 determines that the sputum of the patient needs to be removed and the suction pump 210 and the driving unit The operation start command is transmitted to the 230, and accordingly the entry of the catheter 100 into the respirator is started (S490).

If it is determined in step S450 that the auscultation waveform size of the patient is outside the reference waveform size and the error range, the control unit 270 may next determine the current pulse rate of the patient patient in step S370. It is determined whether the reference pulse rate, which is a preset operation reference value, and a predetermined error range (for example, 5%) are present (S470).

As a result, when it is determined that the current pulse rate of the patient is within the reference pulse rate and the error range, the controller 270 determines that the sputum of the patient needs to be removed, and the suction pump 210 and the driving unit 230 The operation start command is transmitted, and thus the entry of the catheter 100 into the respirator is started (S490).

If it is determined in step S470 that the pulse rate of the patient is outside the reference pulse rate and the error range, the control unit 270 operates as the next step, in which the current oxygen saturation of the patient is preset in step S370. It is determined whether the reference oxygen saturation degree which is a reference value is within a predetermined error range (for example, 5%) (S480).

As a result, when it is determined that the current oxygen saturation of the patient is within the reference oxygen saturation and the error range, the controller 270 determines that the sputum of the patient needs to be removed and the suction pump 210 and the driving unit 230 In operation S490, the command to start operation is transmitted to the respirator of the catheter 100.

On the other hand, in the practice of the present invention, the doctor or nurse by directly diagnosing the condition of the patient, the reference value set through the above-described step S310 to S370 may be arbitrarily set and directly input through the input panel.

In addition, in the practice of the present invention, in sequentially executing the above-described steps S410, S430, S450, S470, S480, it is preferable that the administrator can determine the execution order through the input panel of the medical suction device 200 something to do.

In detail, the manager first arranges state information having a relatively large variation in respiratory volume, respiratory cycle, auscultation sound wave size, pulse rate, and oxygen saturation in consideration of individual characteristics of a corresponding patient. By resetting the priorities of the determinations, it is possible to increase the promptness in determining the operation start of the suction device 200.

In addition, in the practice of the present invention, the control unit 270 may be executed simultaneously without sequentially executing the above-described steps S410, S430, S450, S470, S480, in this case, the administrator of the five determination items It may be possible to increase the accuracy in determining the operation start of the suction device 200 by determining that the sputum needs to be removed only when a certain number (for example, three) or more set through the input panel is satisfied. .
