Hereinafter, the present invention will be described in detail with reference to the drawings. It is to be noted that the same elements among the drawings are denoted by the same reference numerals whenever possible. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

1 is a view showing the structure of an artificial intelligent medical suction unit according to an embodiment of the present invention. The artificial intelligent medical suction unit 200 according to the present invention performs a function of removing foreign substances in the respiratory apparatus by using the catheter 100. To this end, the artificial intelligent medical suction unit 200 includes a suction pump 210 connected to an end of the catheter 100, A heart monitor 220, a driver 230, a stethoscope microphone 240, a pressure sensor 250, a pulse measuring unit 260, a controller 270, and an oxygen saturation measuring unit 280.

First, the suction pump 210 is installed at one end of the catheter 100 and sucks the suction pressure inside the catheter 100 so that foreign substances such as sputum are sucked through the other end of the catheter 100 inserted into the patient's respiratory system .

The sensor unit 220 includes a mass flow meter (MFM) sensor for measuring the mass of the inspiratory gas and the exhalation gas of the patient, respectively, and measures the mass of the inspiratory gas and the exhalation gas of the patient, And transmits the result to the control unit 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 breathing volume of the patient from the breath outlet of the respiratory mask worn by the patient, The second mass flow sensor measures the inspiratory volume of the patient from the inspiratory inlet of the respiratory mask.

On the other hand, the driver 230 moves the catheter 100 forward for insertion into the bronchus of the catheter 100, or moves the catheter 100 backward for removal from the organ of the catheter 100.

The stethoscope microphone 240 measures the stethoscope sound of the patient and transmits the measured stethoscope sound to the control unit 270. The pulse measurement unit 260 measures the pulse rate of the patient and outputs the measured pulse rate to the control unit 270 The oxygen saturation measuring unit 280 measures the degree of saturation of oxygen from the blood sample collected from the patient and transmits the measured degree of oxygen saturation to the control unit 270.

The control unit 270 receives the patient's stutter sound information received from the stethoscope microphone 240, the pulse rate information of the patient received from the pulse measuring unit 260, the patient's oxygen saturation information received from the oxygen saturation measuring unit 280 Based on the patient condition information including the patient's condition, the condition of the patient's bronchus to remove foreign substances such as sputum.

In addition, the pressure sensor 250 measures the pressure (sound pressure) formed inside the catheter 100 and transmits the measured pressure value to the controller 270.

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

First, the control unit 270 of the artificial intelligent medical suction device 200 measures a plurality of patient state information including respiration information of a patient in a normal state (state in which sputum removal is not required) (S310) Is calculated.

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

- cumulative mean value of breathing volume, cumulative mean value of breathing (inspiration / expiration) cycle -

The control unit 270 of the artificial intelligent medical infusion set 200 alternately receives the measurement value of the patient's breathing volume from the first mass flowmeter sensor and the measured value of the inspiration volume of the patient from the second mass flowmeter sensor, ) Can obtain the respiratory volume information per breathing cycle of the patient in real time.

In addition, the controller 270 computes the interval between the time at which the breath breathing volume measurement value is received from the first mass flowmeter sensor and the time at which the next breath breathing volume measurement value is received, thereby determining the breathing (inspiration / breathing) cycle of the patient It becomes possible to measure.

The control unit 270 calculates and stores a cumulative average value of the patient's respiratory volume and also stores a cumulative average value of the respiratory cycles of the patient. And stores it.

- Stethoscope  Cumulative average value of waveform size -

In addition, the controller 270 receives a stethoscopic sound (or a breath sound) from the patient's chest measured from the stethoscope microphone 240 in real time, and performs a waveform analysis as shown in FIG. 3 for the received stethoscope sound. FIG. 3 is a diagram showing the waveform of a stethoscope measured in a state in which a patient has no respiratory disturbance due to sputum or the like, converted into a frequency domain.

The control unit 270 calculates and stores the average value of the maximum amplitudes of the analyzed waveforms for the stethoscope sound received in real time.

- Cumulative mean value of pulse rate -

The control unit 270 receives the pulse rate of the patient in real time from the pulse measuring unit 260 installed on the patient's wrist, and calculates and stores the cumulative average value of the cumulative received pulse rate.

-Oxygen Saturation  Cumulative average value -

The control unit 270 calculates and stores a cumulative average value of the oxygen saturation 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 unit 200, such as a caregiver, a nurse or the like, who cares for the patient, can determine the state of the patient's breathing, And when it is determined that the spill removal is necessary, spill removal is performed by directly driving the suction device 200 through the operation input panel (not shown) of the suction device 200 by manual operation (S330).

In addition, the controller 270 calculates the patient state information measured at the time when the administrator inputs an operation command of the suction device 200 through the input panel for manual operation (that is, when the sputum removal is required) Respectively.

Specifically, the controller 270 compares the measured breathing volume at the time (spike removal required time) with the cumulative average value of the previously stored breathing volume, compares the measured breathing cycle with the accumulated average value of the previously stored breathing cycle, The pulse waveform measured at the time point is compared with the cumulative average value of the stored stochastic waveform waveform size, the measured pulse waveform is compared with the cumulative average value of the pre-stored pulse rate, and the measured oxygen saturation is stored This is compared with the cumulative average value of oxygen saturation.

On the other hand, the controller 270 compares the accumulated cumulative average value of the plurality of patient state information measured at the point of time when the sputum removal is required with the cumulative average value, and obtains the state information in which a deviation of a predetermined ratio (for example, 10% (S350).

Status information Deviation rate from cumulative mean value Adoption of abnormal indicators Volume 15% O Respiratory cycle 17% O Stethoscope waveform size 23% O Pulse rate 5% X Oxygen saturation 3% X

In the present invention, as shown in Table 1, a deviation of a predetermined ratio (for example, 10%) or more from the time point when the suction is performed by monitoring the specific patient directly from the plurality of state information The state information that has occurred is adopted as an abnormality index which is an indicator for positively marking the patient's own state (state requiring removal of sputum) to the outside, because the value of the patient changes significantly due to the occurrence of sputum .

In addition, the control unit 270 checks the measured values measured at the execution time of the manual suction by the manager in response to the state information adopted as the abnormality index, so as to indicate that the patient is in the sputum removal request state Is set and stored as a reference value (S370).

That is, in the present invention, the selected individual reference value for each patient is set as an operation reference value of the suction device 200 in consideration of the body reaction characteristic inherent to each patient, It is possible to perform customized nursing considering the body reaction characteristics for each patient by determining that the state information of the patient is close to the time when the suction device 200 needs to be driven for the patient.

Meanwhile, the respiratory volume, respiratory cycle, stethoscopic waveform size, pulse rate, and oxygen saturation in Table 1 may all be an abnormal index depending on characteristics of each patient, and the specific reason is as follows.

In general, when foreign substances such as sputum accumulate more than a certain degree in the respiratory tract, the respiration of the patient becomes complicated, resulting in a shortening of the respiratory cycle and a decrease in respiratory rate per breathing cycle.

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

In addition, the unconscious patient has difficulty in breathing due to foreign substances from the respiratory system such as sputum, resulting in increased pulse rate of the patient and decreased oxygen saturation.

FIG. 3 is a flow chart illustrating an operation of a method for controlling an artificial intelligent medical suction unit according to an embodiment of the present invention. Referring to FIG. FIG. 3 exemplifies a case where the respiration amount, the respiratory cycle, the size of the stethoscopic sound waveform, the pulse rate, and the oxygen saturation are all adopted as 'abnormal indices' and set as reference values, respectively.

Hereinafter, with reference to FIG. 1 and FIG. 3, a description will be made of a method of controlling an artificial intelligent medical suction unit according to an embodiment of the present invention.

First, the control unit 270 determines whether the respiration rate of the patient received in real time from the sensor unit 220 is greater than the reference respiration rate, which is a predetermined operation reference value in step S370, and a predetermined error range (for example, 5%) (S410).

As a result, when it is determined that the current breathing amount of the patient is within the tolerance range with respect to the reference breathing amount, the controller 270 determines that the spout of the patient is necessary to be removed and the suction pump 210 and the driving unit 230 An operation start command is transmitted, and accordingly, entry of the catheter 100 into the respirator is started (S490).

If it is determined in step S410 that the respiration amount of the patient is outside the reference respiration amount and the error range, the controller 270 determines whether the current respiration cycle of the patient patient is a predetermined operation in step S370 It is determined whether or not the reference period is within a predetermined error range (e.g., 5%) (S430).

As a result, when it is determined that the current breathing cycle of the patient is within the error range with respect to the reference breathing cycle, the control unit 270 determines that the removal of the sputum of the patient is necessary and the suction pump 210 and the driving unit 230 (Step S490). The catheter 100 is then started to enter the respiratory tract.

If it is determined in step S430 that the respiratory cycle of the patient is outside the reference respiratory cycle and the error range, the controller 270 determines whether the current stethoscopy sound waveform size of the patient patient is equal to or greater than the reference breathing cycle (For example, 5%) with the reference waveform size, which is a predetermined operation reference value, at step S450.

As a result, when it is determined that the size of the current stethoscopic sound waveform of the patient is within the error range of the reference waveform size, the controller 270 determines that the removal of the sputum of the patient is necessary, The operation start command is transmitted to the catheter 230 so that the entry of the catheter 100 into the respirator is started (S490).

If it is determined in step S450 that the magnitude of the stethoscopy waveform of the patient is outside the reference waveform size and error range, the controller 270 determines whether the current pulse rate of the patient patient is greater than the reference pulse size in step S370 It is determined whether or not the reference pulse rate is within a predetermined error range (for example, 5%) (S470).

As a result, when it is determined that the current pulse rate of the patient is within the error range from the reference pulse rate, the controller 270 determines that the patient needs to be removed from the sputum, and the suction pump 210 and the driving unit 230 An operation start command is transmitted, and accordingly, 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 error range with the reference pulse rate, the controller 270 determines whether the current oxygen saturation of the patient patient is equal to or greater than the predetermined pulse rate in step S370 It is determined whether or not the reference oxygen saturation 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 error range with respect to the reference oxygen saturation, the controller 270 determines that the removal of the sputum of the patient is necessary and the suction pump 210 and the driving unit 230 (Step S490). The catheter 100 is then started to enter the respiratory tract.

Meanwhile, in implementing the present invention, the reference value set through steps S310 through S370 may be directly set by the doctor or the nurse by directly diagnosing the patient's condition, and may be directly input through the input panel.

In order to implement the present invention, in order to sequentially execute steps S410, S430, S450, S470, and S480 described above, it is preferable that the administrator can determine the order of execution through the input panel of the medical suction unit 200 something to do.

More specifically, the administrator sets the priority information having a relatively large variation width among the respiratory volume, the respiratory cycle, the stuttering sound wave size, the pulse rate, and the oxygen saturation in consideration of the individual characteristics of the patient, By resetting the priority of judgment, it is possible to increase the promptness in determining the operation start of the suction device 200.

In addition, in implementing the present invention, the controller 270 may execute the above steps S410, S430, S450, S470, and S480 without sequentially executing the steps sequentially. In this case, It may be possible to increase the accuracy in determining the start of operation of the suction device 200 by determining that it is necessary to remove sputum only when an arbitrary number (for example, three) set by the input panel is satisfied .
