The suction mode during the operation of the present invention made as described above will be described in detail with reference to FIGS. 7 and 9.

First, the reference value of the target sound pressure is set so that the pressure inside the pulmonary pleura of the patient becomes the sound pressure (S1).

After opening and closing the valve 8 to open the third pipe line P3, the vacuum pump 5 is driven to suck the waste fluid and air inside the pulmonary pleura, and the air flows out through the fifth pipe line P5. Body fluid is stored in the drain collection container (3). At this time, the amount of body fluid flowing into the drainage collection container 3 is measured by the drainage amount sensor 13 in real time and transmits the signal to the control unit 11 to determine whether the body fluid is excessively contained and a certain range. It is determined that it has crossed over and the warning is displayed through the display 23. (S2)

The pressure inside the pulmonary pleura is measured from the pressure sensor 15 connected to the chest tube and the pipe line, and the pressure is compared with the reference value.

On the other hand, when the pressure inside the pulmonary pleura becomes negative pressure after a certain time has elapsed (that is, lower than the reference value), the driving of the vacuum pump 5 is stopped (S4).

Thereafter, in order to prevent the backflow of the air from the vacuum pump 5 to the chest tube P1 side, the pipeline disposed between the vacuum pump 5 and the pressure sensor 15 is closed by the opening / closing valve 8. S5)

The amount of air coming out of the pulmonary pleura is measured through an air flow rate sensor 7 and the measured data is stored for each hour. (S6)

Thereafter, while measuring the pressure inside the pulmonary pleura, it is determined whether the pressure is high compared to the reference value, and if it is high, the step (S2) is performed again (S7).

On the other hand, if the amount of air from the pulmonary pleura is out of a predetermined range, the flushing mode is executed as shown in FIG. 8. That is, when there is a sudden change in the amount of air, it is determined that foreign matter is trapped in the pipeline, and the directional control valve 9 is operated to close the flow to the fifth pipeline P5 and open the sixth pipeline P6 side. Forced circulation so that air can flow through the connecting portion 23 to the drainage collection container 3 side. Afterwards, if a change in air volume is detected within the normal range, the initial state can be maintained again.

In the present embodiment, various warning displays are possible. That is, in the display, when the change in the air volume is out of a certain range, a warning sign may appear, a warning sign may appear when the battery is low, and a warning sign may appear even when the drainage bottle is full.

In addition, the control of the vacuum pump may also be manually operated by the user in the manual mode, and may be automatically controlled by the controller as described above.

In addition, the flushing mode is not necessarily made according to the change in the amount of air, but may be automatically activated when the time set for the timer is set with a separate timer. That is, of course, it is possible to set, such as operating for 10 seconds every 5 minutes.

In addition, the timer may be such that the pump automatically operates when a certain time elapses so that the body fluid or air in the pulmonary pleura may be automatically inhaled. That is, as described above, in addition to the case where the pressure inside the pulmonary pleura falls below a certain level, it is also possible to perform the operation of a conventional vacuum pump every predetermined time. This is to remove fluids that may be standing in the pulmonary pleura or on the duct connected to the human body after a certain time.

As described above, the embodiment of the present invention can help to automatically measure and record the degree of air leakage due to pleural injury of a patient, to make a database, to quantitatively analyze, and to establish a systematic treatment plan. The embodiment can implement a quantitative measurement of the amount of air leakage while performing the discharge function of the body fluid as a single device.

In addition, the control unit 11 frequently transmits the data stored in the data storage unit 21 to the main computer device of the hospital that the medical staff can see or the communication device carried by the medical staff through the wireless communication module 19. Therefore, the medical staff can check the patient's condition in real time.

Therefore, an embodiment of the present invention allows a patient to move around the hospital freely, thereby increasing the recovery speed of the patient, and the medical staff can perform systematic medical actions by using the measured data in real time, standardization of medical care, rationality and Can improve the accuracy.

The portable body fluid discharge device according to the present invention may be modified as follows.

In the above embodiment, the pressure sensor and the air flow rate sensor is used as an example, but only the pressure sensor may be used. In this case, however, the pressure sensor may be programmed to measure the air flow rate. That is, the pressure sensor is to measure the amount of change per hour between the predetermined pressure indirectly calculates the air flow according to the control unit to be able to store the amount of air flowing in the pipe in the control unit.

In addition, in the above-described embodiment, a plurality of components, such as a vacuum pump, a pressure sensor, a controller, a drainage sensor, etc. have been described, but all are arranged in one case, but the present invention is not limited thereto. Of course, it is also possible to be installed in each case in the state.
