In the case of the IoT-based fluid amount monitoring system according to the present invention, as shown in FIG. 1, the user, that is, the patient's solution bag, which contains the fluid to be administered (Ringer's solution bag), accurately monitors the progress and monitors this information On the basis of this, it is to enable managers, for example, nurses and the like, to take appropriate medical services in a timely manner.

Although there have been many technical attempts to inform the timing of replacement of the sap bag 10 by measuring the weight of the sap bag 10, in fact, most of the existing techniques are limited to a conceptual approach. It was a reality that there were many difficulties in applying to the site due to the lack of detailed completeness.

For example, despite various errors and abnormal information being observed in the sap bag 10 of reality, attempts in the existing patent information simply exist, and there is only an ideological approach to the outside, which lacks recognition of this practical problem itself. It was true, and of course, this conceptual approach alone had a large crowd to be applied to the field.

As shown in Figure 1, in the case of the IoT-based fluid amount monitoring system according to the present invention, RM unit (resistor measuring unit, 100), arm band (arm band, 201), code reading unit (code reading unit, 200) , And a monitoring unit (300).

First, in the case of the RM unit 100, as shown in FIGS. 1 and 2, provided between the ringer 1 and the sap bag 10, the electrical resistance information according to the weight of the sap bag 10 By acquiring, the resistance information is networked and transmitted to an external terminal, for example, the monitoring unit 300.

In the case of the RM unit 100, the ringer 1 is present at the top, and the sap bag 10 is present at the bottom thereof, as well as the own weight of the RM unit 100, as well as the sap bag 10. The weight is accommodated, and according to the change in the electrical resistance value that can be generated differently according to the weight, ultimately, the condition of the sap bag 10, that is, the remaining capacity is grasped.

The RM unit 100 differs from the existing commercially available load cell or electronic balance in a detailed technical system, which will be described later.

In the case of the arm band 201, as shown in FIG. 1, a user, that is, mounted on a part of the patient's body, for example, a cuff, code information matching the patient information is printed and presented to the outside.

In the case of the code information presented by the arm band 201, it may be a general bar code or a quick response code (QR code). When the code information is recognized, the recognized code information is transmitted to the currently recognized code. It is recognized who the patient is according to the information, and accordingly, while the information of the RM unit 100 is simultaneously received, the monitoring unit 300 initiates monitoring of the condition information of the infusion bag 10.

The patient information above may reflect not only the personal personal information of the patient, but also the disease information of the patient managed by the hospital, as well as information about what fluid is currently being administered, and the fluid currently recognized by the RM unit 100 The condition information of the bag 10, that is, information about the remaining capacity of the sap bag 10 is linked to the patient information to be reflected.

The code reading unit 200 is generally sufficient if a commercially available product such as a code reader or a code scanner is used, so a separate description is omitted.

In addition, since the code reading unit 200 can be recognized through a camera of a smartphone or a tablet PC, there will be no limitation in the tangible part.

As shown in FIG. 1, in the case of the monitoring unit 300, the patient information recognized by the code reading unit 200 is networked with the RM unit 100 and also with the code reading unit 200.

That is, the hook link 110 is hung on the ringer 1 at the top, and the sap bag 10 is suspended at the bottom to bear the weight of the sap bag 10 and, according to the change in weight, will be described later. The change in the electrical resistance in the resistance detection unit 120 is caused.

In the case of the resistance detection unit 120, the current applied from the battery unit 102 is received to detect a change in electrical resistance information according to a change in weight received by the hook link unit 110.

The specific mechanism of the resistance detector 120 will be described later.

In the case of the resistance information transmitting unit 130, it is a configuration that transmits electrical resistance information sensed by the resistance detecting unit 120 to the monitoring unit 300.

In the case of the pressure conduction unit 121, it is made of a soft soft material, and contains a conductive material therein to provide a predetermined electrical resistance.

In the case of the pressure conduction unit 121, it is formed convex downward and presses the pressure-conducting conductor portion 122 through a downward convex shape.

In the case of the downward convex shape of the pressure conduction unit 121, since it is made of soft soft, the area in contact with the pressure conductor portion 122 linearly increases according to the degree of pressure.

In the case of the conductive wire portion 122, as shown in FIG. 4, a plurality of conductive branches facing each other are provided, and each of the plurality of conductive branches is spaced apart from each other in parallel to face each other symmetrically.

As described above, the pressure conduction unit 121 faces each other of the pressure-conducting conductors 122 in the shape of a downwardly convex soft material, and presses and covers the top surfaces of a plurality of conduction branches spaced apart in parallel. Depending on the degree, the number of branches interconnecting a plurality of conducting branches spaced apart from each other in parallel increases, and accordingly, the resistance information of the electrical resistance between the pressure-conducting conductors 122 changes according to the degree of pressure.

Referring to Figure 4 (b), the lower link portion (110b) is connected to the pressure conduction unit 121 to press downward, and the upper link portion (110a) is connected to the pressure conducting portion 122 for the downward force Take a supporting role to ensure that they are oppressed.

In the case of the code information receiving unit 310, the code information sensed by the code reading unit 200, for example, barcode or QR code information is read, and this is compared with the code information matched with the patient information from the storage unit 302, Make sure to recognize who the patient is with the currently read code information.

In the case of the resistance information receiving unit 320, the resistance information from the resistance information transmitting unit 130 as described above is received and transmitted to the abnormality information detecting unit 350.

In the case of the abnormal information detection unit 350, as described above, the resistance information measured by the RM unit 100 is provided from the resistance information receiving unit 320, and the resistance information is mapped to information according to the transition of several years. Then, the normal information and the abnormal information are segmented through the matched resistance information.

In the case of the linear signal extraction unit 340, only the normal information is extracted and received from the abnormal information detection unit 350, and a determination is made as to whether or not the replacement signal of the sap bag 10 according to the normal information is generated.

First, in the case of the abnormal information detection unit 350, as shown in FIG. 6, a differential (351) may be included.

In the case of a differentiator (351), resistance information is mapped to coordinates according to a change in time, and a change rate of resistance according to a change rate of time is calculated.

In this case, the differential (351) is a constant for the rate of change of the resistance information according to the rate of change of time after converging the width of the rate of change of time to 0 in the rate of change of resistance information according to the rate of change of time Variables are extracted.

In this case, in the case of the monitoring unit 300 of the IoT-based fluid amount monitoring system according to the present invention, the default setting unit 330 may be further included.

The default setting unit 330 receives resistance information from the resistance information receiving unit 320, and if the steady signal lasts for a predetermined time, for example, 3 seconds to 5 seconds, the default resistance information is used. In this case, in this case, the linear signal extraction unit 340, as shown in FIG. 8, the rate of change of resistance information according to the rate of change of time from the differential (differentiator, 351), if the constant, the default weight information 100 After setting to %, when the resistance information becomes less than or equal to the threshold value Th compared to the default resistance information, a replacement signal is generated.

Here, the threshold value means a weight percentage that requires replacement of the sap bag 10, and may be appropriately set according to the capacity of the sap bag 10 and the type of sap stored in the sap bag 10. The threshold value against the default resistance information may be set to 5% to 10% of the total 100%.

As illustrated in FIG. 9, when a user, that is, a patient or a nurse, adjusts the speed at which the fluid exits through the adjustment of the clamp 30, the resistance information is linear, but the slope may change. In case the linear slope is not detected by the SI sensing unit 353 or the PI sensing unit 353 or the FS sensing unit 355, it is classified as a normal signal. If it corresponds to the threshold Th as described above, a replacement signal is generated.

The replacement signal may be transmitted to the manager terminal 50, which will be described later, or may be transmitted to the RM unit 100 as shown in FIG. 7 to generate a visual alarm to the outside through the alarm unit 140.

6, 10 and 11, in the case of the abnormality information detection unit 350 of the IoT-based fluid amount monitoring system according to the present invention, it may include an OS detection unit 352.

In the case of the OS sensing unit 352, the resistance information change rate according to the rate of time change is received from the differential 351 as described above to detect whether the rate of change of resistance information is variable according to the rate of change of time.

10 or 11, after the external force of the sap bag 10, that is, the external force is strongly applied or the weight of the sap bag 10 recognized by the RM unit 100 rapidly disappears depending on the actual situation. In some cases, it may return to its original position again. When this external force occurs, an overshoot occurs as illustrated in FIG. 10 or an undershoot occurs as illustrated in FIG. 11. .

In the case of a signal according to an external force generated in FIG. 10 or 11, it may be a meaningful signal or a meaningless signal depending on the degree of the duration. In the case of a meaningful signal, it means that it does not return to a normal linear signal according to this external force. On the contrary, in the case of a meaningless signal, it can be said to return to a normal linear signal quickly after such an external force occurs.

The signal in FIGS. 10 and 11 corresponds to a case where the rate of change of resistance information according to the change of time according to the analysis of the differential 351 is a variable. In Fig. 10 or 11, if the section where the rate of change of the resistance information is variable lasts more than 5 seconds, or even if it is less than 5 seconds, if an external force is generated and does not return to the in-line linear signal, the error information detector 350 ) Is judged by the abnormal information, and in the future, the administrator terminal 50 will be informed.

In the case of the abnormal information detection unit 350 of the IoT-based fluid amount monitoring system according to the present invention, a deep incline (SI) detector 353, a positive incline (PI) detector 354, and a flat signal (FS) detector (355) may be further included.

First, in the case of the SI detection unit 353, as illustrated in FIG. 13, a case in which a red dotted line with an excessive slope progresses may occur instead of the normal linear resistance information (green dotted line).

In the case of the SI sensing unit 353, if the resistance information change rate according to the rate of change of time is received by the differential 351, and the rate of change of resistance information according to the rate of change of time is a negative constant equal to or less than the critical rate of change, the sap flows out. State.

One drop is usually defined as 0.05 ml, and when calculated as 0.05 g per drop in the case of pure water, a critical rate of change can be set below a slope of -0.05 g/1 sec, which is 1.0 drop or more per second. When this slope is converted in minutes, it can be set to -3.0g/1min. Of course, it can be estimated at 1.5 drops per second or 2.0 drops per second. The critical rate of change is a value that can be arbitrarily set.

In the case of the PI sensing unit 354, as shown in FIG. 14, when receiving the rate of change of resistance information according to the rate of change of time from the differential 351, when the constant is positive, the backflow of the sap bag 10 It detects the (countercurrent　flow) state and notifies it to the manager terminal 50.

In the case of the FS detection unit 355, as shown in FIG. 12, the resistance information change rate according to the rate of change of time is received from the differential 351, and the rate of change of resistance information according to the rate of change of time is zero and this state is predetermined. If it lasts for more than 3 seconds, for example, it detects that the flow of the fluid from the fluid bag 10 is in a stopped state and transmits this information to the manager terminal 50.

In the case of the monitoring unit 300 of the IoT-based fluid amount monitoring system according to the present invention, as illustrated in FIG. 5, an information transmission unit 360 may be further included.

As described above, the information transmission unit 360 receives an overspeed outflow condition from the SI detection unit 353, detects a reverse flow condition from the PI detection unit 354, or receives a flow stop state from the FS detection unit 355. If it is, the manager terminal 50, that is, a nurse or a doctor's terminal, for example, a personal computer (PC), a tablet PC (tablet PC), the patient's sap bag 10, the condition information, that is, normal information, replacement It allows the administrator to recognize signal generation or abnormal information (overshoot, overspeed outflow, backflow, and stoppage).
