Advantages and features of the present invention, and a method of achieving the same will become apparent with reference to the embodiments described later in detail together with the accompanying drawings.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. The same reference numerals in each drawing indicate the same member.

1 is a view showing the configuration of a ringer liquid remaining amount monitoring device according to an embodiment of the present invention.

Referring to FIG. 1, the ringer liquid residual amount monitoring device 100 may be mounted on one end of the ringer hanger 400, and a ring may be provided on the other side to hang the ringer. At this time, the measured ringer residual amount information may be transmitted to the monitoring server 300 through the wireless terminal 200, and the monitoring server 300 may send measures according to the ringer residual amount to a nurse, a guardian, or the like.

Hereinafter, detailed configurations and embodiments of the Ringer's liquid residual amount monitoring device for implementing the above functions will be described in more detail.

2 is a view showing the configuration of a Ringer liquid residual amount monitoring device using a load cell sensor according to an embodiment of the present invention.

Referring to FIG. 2, the Ringer liquid remaining amount monitoring device 100 includes a housing 110, a sensor holder 120, a load cell sensor 130, a Ringer holder 140, a controller 150, and a display unit 160. .

The housing 110 serves as a case for mounting a plurality of modules therein, and may be provided in various shapes by adding design elements such as a polyhedral shape.

The sensor holder 120 is provided at one side of the lower end of the housing and serves to fix the sensor. The fixing method can be variously changed according to the shape of the sensor.

The load cell sensor 130 is fixed in a horizontal or vertical direction by the sensor holder 120, senses the weight corresponding to the Ringer cradle 140 attached to one surface, outputs it as a voltage, and senses using the output voltage. You can measure the weight.

The ringer cradle 140 may include a hook on one side and have a bar shape in which a rotation shaft is provided in the center, and rotate according to the weight of the ringer around the rotation shaft fixed on one surface inside the housing, and the load cell sensor 130 ) Can be pressurized.

The controller 150 may calculate the remaining amount of Ringer's liquid using an output voltage corresponding to the sensed weight of the load cell sensor 130 and transmit the calculated remaining amount information to the outside. For example, the controller 150 may transmit the remaining amount information to a monitoring server through a wireless terminal to control the monitoring server to take an action corresponding to the remaining amount.

The display unit 160 may display information on the remaining amount of Ringer's liquid calculated by the controller 150. Depending on the user's settings, desired information such as patient information, Ringer's remaining amount, and administration time can be displayed.

On the other hand, the controller 150 measures the weight of the first input Ringer liquid, stores the initial measured weight M _init , stores the minimum weight M _min that can be detected by the load cell sensor 130, and reduces the Ringer liquid compared to a preset time. After calculating the reduction rate of Ringer's liquid for each section according to the preset time based on the weight, the reduction rate of Ringer's liquid in the section with the largest reduction rate is V _max , and the reduction rate in the section just before M _min sensing is stored as V _fin . It is characterized by sending a notification signal after calculating the information on the remaining amount of Ringer's liquid and the input completion time by using each pre-stored reduction rate.

For example, assuming that the capacity of Ringer injected into the patient at 11 am is 800ml and the weight measured by the load cell sensor 130 is 800g, the initial Ringer's liquid weight M _init is stored in the controller 150 as 800g. do. It is assumed that the minimum sensing weight M _{min determined} by the controller 150 is 100 g.

On the other hand, if the unit time is set to 20 minutes to calculate the Ringer's amount reduction per unit time, the interval is set every 20 minutes from 11 am, the first time Ringer was introduced to the patient, and the amount of Ringer's amount reduction per unit time within the predetermined interval is calculated. Can be calculated. At this time, since the injection speed of Ringer's solution that is injected by the operation of the patient or the nurse can be adjusted, the amount of reduction for each predetermined section may not be constant. Accordingly, V _max , which is the maximum reduction rate of Ringer's solution, can be calculated by comparing the reduction amount for each section.

When the Ringer's solution weight reaches M _min , the injection completion time of Ringer's solution can be predicted using the V _max , and the predicted minimum completion time and the patient's information are stored in the devices of the first group designated as nurses and hospital managers. Send a notification. At the same time, based on the time reaching M _min , the input completion time of the Ringer's solution is re-predicted using V _fin, which is the rate of Ringer's solution reduction in the previous section, and the timer is operated at the re-predicted time. Thereafter, when the timer expires, the second notification is transmitted to the devices of the first group and the second group, which are designated as guardians of the patient.

3 is a diagram showing a graph of a change rate of Ringer's solution for each section for detecting a change of Ringer's solution according to an embodiment of the present invention.

Referring to FIG. 3, a predetermined amount of change in Ringer's solution per hour can be expressed as a graph. Considering the x-axis and y-axis as time and reduced Ringer weight, respectively, the amount of change in Ringer's amount per hour means the rate of decrease, and can be expressed as a slope for each section on the graph. At this time, n sections are divided every t minutes based on the initial input time of Ringer's solution, and the slope of each section of S1 ~ Sn can be calculated.

For example, if the point at which M _min is detected by the controller 150 is 4t minutes or later, V _max is the reduction rate in the steepest S2 section, and the estimated injection completion time and the patient using V _max Information is transmitted to a predetermined first group of devices. At the same time, the reduction rate in the S4 segment immediately preceding interval of the detected time point is stored in the M _min V _fin, using a V _fin operates a timer to re-estimate the input completion time of the Ringer's solution. When the timer expires, a notification is sent to the devices of the first and second groups, indicating that the patient's information and the ringer are completely exhausted.

On the other hand, when the slope is 0 as in the S3 section, it means that the Ringer's solution is not being normally injected, and thus a warning notification is sent to the devices of the first and second groups notifying the patient's information and a dangerous situation. In addition, when the patient's blood flows back and the weight of Ringer's solution increases, that is, when the slope is negative, or when the administration of Ringer's solution increases non-statically compared to the decrease in the previous section after Ringer is injected, that is, the slope increases by more than 2 times compared to the previous section Even in the case, the above warning notification is sent.

4 is a block diagram illustrating a process of detecting a change in Ringer's solution and sending an alarm signal according to a situation according to an embodiment of the present invention.

Referring to FIG. 4, three types of notification signals transmitted by the controller 150 may be more clearly understood.

In more detail, the controller 150 may store the Ringer's solution input time and the initial weight M _init . After that, the amount of Ringer's solution reduction is stored for each section, and when Ringer's solution is normally administered, the reduced weight of Ringer's solution senses M _min , the minimum weight that the load cell sensor 130 can recognize, and uses the patient's information and V _max . Thus, the predicted Ringer's amount input completion time can be sent to a predetermined first group.

The second notification signal is, after calculating the time it takes for Ringer's solution to reach 0 ml by using the V _fin, and when the timer preset with the calculated time is completed, the predetermined first group and the second group of devices The information of the patient and the notification of the completion of the Ringer's solution are transmitted to.

In more detail, after the first notification signal is sent, the timer is set by re-predicting the completion time of Ringer's solution injection using the speed V _fin in the section immediately before M _min sensing, and when the preset timer time is completed, the patient You can send out a warning notification that your information and Ringer's amount are completely exhausted.

The third notification signal is a notification that detects a malfunction of Ringer injection and warns of the patient's information and malfunction to the predetermined first group and second group devices when the calculated Ringer's liquid reduction rate is out of a preset range. Means.

More specifically, if the slope of the predetermined range is less than 0 or more than twice the slope of the previous section, a warning notification can be sent to promptly check the patient's condition by detecting a dangerous situation in which the Ringer's solution is injected abnormally. have.
