Description

TECHNICAL FIELD [0001] The present invention relates to a liquid measuring apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fluid analyzer and a control method thereof, and more particularly, to a fluid meter that measures the weight of a fluid container containing fluid and monitors the state of infusion.

Generally, intravenous injection therapy is used in which a needle is directly inserted into a vein to administer a solution, medicine, blood, etc. to a patient and administers a solution, drug, blood and the like. At this time, the nurse should check whether the fluid is exhausted at regular intervals and replace it with another fluid or remove the needle from the patient's body to prevent medical accidents such as blood coagulation or air injection in the needle.

However, due to the excessive workload or carelessness of the nurse, it is impossible to grasp the completion time of the administration of the sap, and the replacement of the sap and the removal of the needle may not be performed in a timely manner, which may cause great pain to the patient.

Therefore, it is necessary to calculate the infusion rate of the infusion fluid in order to determine when the infusion of the infusion solution is completed, to calculate the expected infusion time, and to determine the completion time of infusion of the infusion solution by the weighing method.

On the other hand, the method for measuring the remaining amount of liquid in the weight measuring method among the methods for grasping the time point of completion of the above-mentioned liquid administration is a method of setting the threshold value in consideration of the weight of the liquid + When the value obtained by subtracting the weight of the liquid set is 0, it provides a method of determining whether the liquid is completely administered.

However, the above-described method is troublesome to input new information depending on the type of the liquid, the liquid container or the liquid set, and it is difficult to calculate the accurate threshold value. In addition, since the accuracy of measurement of the remaining amount of fluid is lowered due to the occurrence of errors, it is difficult to accurately grasp the time point when the administration of the liquid is completed, leading to a medical accident.

Therefore, a new method for improving the accuracy of remaining amount measurement is required in the method of measuring the remaining amount of fluid by weighing.

In the drawings, like reference numerals refer to the same or similar functions throughout the several views.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

FIGS. 1A and 1B are diagrams showing an actual use example of a fluid analyzer according to an embodiment of the present invention.

Referring to FIG. 1A, a fluid measurement device 100 according to an exemplary embodiment of the present invention may measure the weight of a fluid pack 200a containing a fluid 300 therein.

Referring to FIG. 1B, the fluid sensor 100 according to an embodiment of the present invention can measure the weight of the fluid bottle 200b containing the fluid 300.

More specifically, the fluid analyzer 100 measures the weight when the fluid receptacle 200a or the fluid receptacle 200b containing the fluid 300 is mounted on the receptacle of the fluid receptacle at the bottom of the fluid measuring device 100, The weight of the fluid 300 can be calculated from the total weight.

Here, the fluid (300) may be replaced with a drug, blood, or the like that can be administered to a patient at the time of intravenous injection therapy.

1B is a perspective view of a liquid container 200a according to an embodiment of the present invention. The liquid container 200a is a pack in which a liquid 300 can be contained. However, ). ≪ / RTI >

In order for the fluid sensor 100 to calculate the weight of the fluid 300 from the weight of the fluid pack 200a or the fluid bottle 200b containing the fluid 300, The standard of the container and the weight data of the liquid can be used.

Referring to FIG. 2, data indicating the type of the fluid receptacle, the capacity of the fluid receptacle, and the weight of the fluid are classified according to the weight of the fluid receptacle containing the fluid.

Here, the type of the liquid container is limited to a pack and a bottle. However, if the liquid container is a container capable of containing liquid, another kind may be added. In addition, if the fluid dispenser 100 can recognize the weight difference of the type of the fluid container according to the material, it can be classified into a PVC pack, a plastic bottle, a glass bottle, and the like. The capacity of the fluid container may be variously classified as necessary, and even if the types of the fluid containers are different, the weight of the fluid that can be contained in the fluid container may be the same if the capacity of the fluid container is the same. Further, the above-described data may be modified, added or deleted in accordance with the specification of the liquid container handled in a hospital.

For example, when the weight of the liquid container containing the liquid measured by the liquid receiver 100 is 128 g, the type of the liquid container can be determined as a pack and the capacity of the liquid container can be determined as 100 ml have. Accordingly, the weight of the liquid can be calculated as 110 g.

If the weight classification data of the fluid container containing the fluid does not have the same value as the weight measured by the fluid analyzer 100, the weight data of the fluid container having the value closest to the weight measured by the fluid analyzer 100 It is possible to determine the specification of the liquid container measured by the liquid receiver 100.

In other words, when the weight of the liquid container containing the liquid measured by the liquid receiver 100 is 150 g, the type of the liquid container according to the value of 148 g closest to 150 g is referred to as a bottle, The capacity can be determined as 100 ml. Accordingly, the weight of the liquid can be calculated as 110 g.

Referring to FIG. 1A, a liquid pack 200a containing the liquid 300 may be prepared, and the liquid pack 200a may be attached to the liquid container holder at the bottom of the liquid measuring device 100. FIG. At this time, if the weight of the sap pack 200a containing the sap 300 is measured and the measured weight is 528 g, the type of the sap is determined according to the weight classification data of the sap column containing the sap. The capacity of the pack and the liquid container can be determined to be 500 ml. Accordingly, the weight of the liquid 300 contained in the liquid-receiving container 200a can be calculated as 510 g.

Referring to FIG. 1B, the liquid bottle 200b containing the liquid 300 may be prepared, and the liquid bottle 200b may be attached to the liquid container holder at the lower end of the liquid receiver 100. FIG. At this time, if the weight of the sap bottle 200b containing the sap 300 is measured and the measured weight is 548 g, the type of the sap is determined according to the weight classification data of the sap containing the sap. The volume of the bottle and the fluid container can be determined as 500 ml. Accordingly, the weight of the liquid 300 contained in the liquid bottle 200b can be calculated as 510 g.

That is, if the user simply mounts the liquid container 200a containing the liquid fluid 300 or the liquid container of the liquid fluid bottle 200b to the liquid analyzer 100, even if there is no separate data input, The capacity of the fluid container, and the weight of the fluid 300 contained in the fluid container.

3A, a fluid measurement device 100 according to another embodiment of the present invention measures the weight of the fluid 300 by measuring the weight of the fluid pack 200a containing the fluid 300, 300 can be re-measured to the weight of the fluid set 400 connected to the fluid pack 200a.

3B, the fluid measurement device 100 according to another embodiment of the present invention measures the weight of the infusion bottle 300 by measuring the weight of the infusion bottle 200b containing the infusion solution 300, 300 can be measured again by connecting the fluid set 400 to the fluid container 200b containing the fluid.

More specifically, the weight of the fluid pack 200a or the fluid bottle 200b containing the fluid 300 is measured, the weight of the fluid 300 is calculated according to the weight measured as described above, The fluid measurement device 100 measures the weight of the fluid pack 200a or the fluid bottle 200b connected to the fluid set 400 when the fluid set 400 is connected to the fluid pack 200a or the fluid bottle 200b can do. Here, the liquid set 400 is an apparatus for administering the liquid 300 to the patient, and may be constituted by a transfer tube, a lever, a control valve, an injection needle, or the like.

The weight of the sap is calculated by subtracting the weight of the sap solution 300 calculated from the weight of the sap set 400 connected to the sap solution 200a or the sap solution 200b containing the sap solution 300, It can be set as a threshold value for determining whether or not it is completed. That is, the sum of the weight of the empty fluid pack 200a or the empty fluid bottle 200b and the weight of the fluid set 400 may be set to a threshold value.

When the threshold value is set, the fluid measurement device 100 measures the weight of the fluid set 200a or the fluid set 200b including the fluid set 300 connected thereto in real time or according to a predetermined time interval, To monitor whether the weight has reached a threshold and to generate an alarm.

Meanwhile, according to another embodiment of the present invention, an alarm may be generated when the difference between the measured weight and the threshold is 0.5 g, and as the intensity approaches 0.5 g to 0 g, May be removed from the patient's body in a timely manner or the fluid 300 may be replaced. Here, the difference between the measured weight and the threshold value for determining the start point of the alarm occurrence can be changed by the setting of the user. The user receives an alarm from the fluid sensor 100 and removes the needle from the patient's body or replaces the fluid 300 and inputs the weight of the fluid 300 calculated by inputting the zero point button of the fluid meter 100, And the zero point of the weight can be adjusted.

For example, referring to FIG. 3A, the fluid sensor 100 measures the weight of the fluid pack 200a containing the fluid 300, and when the measured weight is 528 g, the weight of the fluid container containing the fluid The weight of the sap solution 300 contained in the sap solution pack 200a according to the data can be calculated as 510 g.

When the receiver 400 is connected to the receiver 400a by the user, the receiver 400 can measure the weight of the receiver 400 by the amount of the receiver 400 at the initial measured weight. At this time, if the measured weight is 554 g, 510 g, which is the weight of the liquid 300 calculated at 554 g, can be subtracted, and 44 g can be set as a threshold value for determining completion of the administration of the liquid 300.

In addition, the weight of the liquid receiver 200a connected to the liquid receiver set 400 can be measured in real time, and the weight can be monitored from 510 g until the threshold value of 44 g is reached to generate an alarm. When the difference between the measured weight and the threshold value is set to 0.5 g, the alarm generation is started when the weight of the sap pack 200a connected to the set 400 for monitoring in real time is 44.5 g As the weight of the fluid pack 200a connected to the fluid set 400 is lighter, the frequency and intensity of the alarm are changed, and the alarm can be maintained until the zero button is input by the user. When the user presses the zero point button, the weight of 510g and the threshold value 44g, which is the weight of the calculated liquid 300, can be initialized and the zero point of the weight weight can be adjusted.

Hereinafter, with reference to FIGS. 4A and 4B, a specific control procedure of the fluid analyzer according to another embodiment of the present invention can be described.

Referring to FIG. 4A, the control procedure of the fluid analyzer 100 can be confirmed before the administration of the fluid into the patient's body starts.

First, the fluid analyzer 100 can measure the weight of the fluid container containing the fluid (500). The fluid analyzer 100 can measure the weight of the fluid container 100 when the fluid container containing the fluid is mounted on the fluid container hanger provided at the bottom with the zero point adjusted by the user's input signal.

Also, the fluid analyzer 100 may calculate the weight of the fluid from the measured weight of the fluid receptacle (510). The fluid analyzer 100 stores the standard information of the fluid container classified according to the weight of the fluid container containing the fluid and the weight data of the fluid in advance, compares the measured weight with the previously stored data, and if there is the same weight information, The size information of the classified liquid container can be determined as the standard of the measured liquid container. Here, the specification of the liquid container may include the type of the liquid container and the capacity of the liquid container, and the weight of the liquid may be calculated according to the capacity of the liquid container.

At this time, if the weight classification data of the liquid container containing the liquid does not have the same value as the weight measured by the liquid receiver 100, the weight classification data of the liquid container having the value closest to the weight measured by the liquid receiver 100 Accordingly, the specification of the liquid container measured by the liquid receiver 100 can be determined.

For example, when the weight of the liquid container containing the liquid measured by the liquid receiver 100 is 148.2 g, the type of the liquid container according to 148g, which is closest to 148.2g, , And the capacity of the liquid container can be determined as 100 ml. Accordingly, the weight of the liquid can be calculated as 110 g.

Meanwhile, the fluid analyzer 100 may calculate the weight of the fluid and measure the weight of the fluid container connected to the fluid set (520). When the user mounts the liquid receiver in the liquid receiver and the weight measured by the liquid receiver 100 increases, the liquid receiver 100 recognizes that the liquid receiver is connected and measures the weight by the weight of the liquid container to which the liquid receiver is connected can do.

Further, the liquid receiver 100 may set a value obtained by subtracting the weight of the liquid calculated from the weight of the liquid receiver to which the liquid receiver is connected, as a threshold value (530). That is, the liquid receiver 100 measures the sum of the weights of the liquid set, which is the sum of the weights of the liquids contained in the liquid set, the liquid container and the liquid container, minus the weight of the liquid contained in the liquid container, Can be set. The set threshold can be used to determine the status of fluid administration. When the threshold value is set, the fluid analyzer 100 can determine that the administration of the fluid into the patient's body has started.

Referring to FIG. 4B, the control procedure of the fluid analyzer 100 can be confirmed until the administration of the fluid into the patient's body is started and it is determined that the administration of the fluid is completed.

First, the fluid analyzer 100 can measure the weight of the fluid receptacle to which the fluid set is connected (600). At this time, depending on the user's setting, the weight of the liquid container can be measured in real time or can be measured at regular time intervals. That is, when it is determined that the administration of the liquid is started to the body of the patient, the liquid receiver 100 measures the weight of the liquid container connected to the liquid receiver set in real time according to the user's setting, Can be monitored.

Further, the fluid analyzer 100 may determine 610 whether the weight of the fluid container to which the set of fluid to be monitored has reached the set threshold value. Since the threshold value is equal to the sum of the liquid set and the empty liquid container, it can be judged that the liquid administration is completed when the weight of the liquid container connected to the measured liquid set reaches the threshold value.

If the liquid receiver 100 determines that the weight of the liquid container connected to the liquid receiver does not reach the predetermined threshold value, the procedure may be repeated to measure (600) the weight of the liquid container to which the liquid receiver is connected.

On the other hand, if the liquid receiver 100 judges that the weight of the liquid container connected to the liquid receiver has reached the set threshold value, it can recognize that the liquid administration is completed and generate an alarm warning 620. At this time, the alarm warning can be repeated until the user inputs a zero point signal to the fluid sensor 100, thereby informing the user that the injection of fluid has been completed so that the needle of the patient can be removed in time or new fluid can be administered .

Meanwhile, FIG. 4C is a flowchart showing a specific control procedure of the liquid receiver according to another embodiment of the present invention.

Referring to FIG. 4C, the control sequence of the fluid analyzer 100 can be confirmed until the time when the administration of the fluid into the body of the patient starts and the fluid administration is determined to be completed, as shown in FIG. 4A.

First, the fluid analyzer 100 can measure the weight of the fluid receptacle to which the fluid set is connected (700). At this time, depending on the user's setting, the weight of the liquid container can be measured in real time or can be measured at regular time intervals. That is, when it is determined that the administration of the liquid is started to the body of the patient, the liquid receiver 100 measures the weight of the liquid container connected to the liquid receiver set in real time according to the user's setting, Can be monitored.

Further, the fluid analyzer 100 may determine whether the weight of the fluid receptacle to which the set of fluid to be monitored has reached the threshold value + alpha (710). When the weight of the liquid receiver connected to the liquid receiver to be monitored according to a preset α is near the threshold value, the liquid receiver 100 determines the weight of the liquid container to which the liquid receiver is connected to the threshold + α It is possible to judge whether or not it has arrived.

If the liquid receiver 100 determines that the weight of the liquid receiver connected to the liquid receiver has not reached the threshold value + alpha, the weight of the liquid receiver connected to the receiver may be measured 700 and monitored.

On the other hand, if the liquid receiver 100 determines that the weight of the liquid container connected to the liquid receiver has reached the threshold + alpha, it may generate an alarm warning 1 step (720). Since the threshold is equal to the sum of the weight of the empty vessel and the weight of the set of liquids, when the monitored weight is equal to the threshold, an alarm alert is initiated to allow the user to determine the completion of the administration of the fluid, Work can be delayed. Therefore, the fluid analyzer 100 can start to generate an alarm when the weight of the fluid receptacle to which the fluid set connected to the predetermined threshold value + is reached reaches the user, thereby informing the user in advance that the fluid dispensing completion time is approaching.

Also, the liquid receiver 100 may determine whether a zero point control signal is input in a state where the alarm warning 1 step is being generated (730). The zero point control signal can be input by the user.

When the liquid receiver 100 determines that the zero point control signal has been input, it can terminate the generation of the alarm warning 1 step. In addition, the fluid analyzer 100 can initialize the zero point of the weight according to the zero point control signal, the set threshold value, the weight of the calculated fluid, and the like.

On the other hand, if it is determined that the zero point control signal is not input, the fluid analyzer 100 may determine whether the weight of the fluid receptacle connected to the fluid set has reached a threshold value (740). The threshold value is equal to the sum of the weight of the empty vessel and the weight of the set of the liquid so that when the monitored weight reaches the threshold value, the liquid analyzer 100 can judge that all of the liquid contained in the vessel has been administered.

When the liquid receiver 100 determines that the weight of the liquid receiver connected to the liquid receiver has not reached the threshold value, it determines again whether the zero point control signal has been input. If the zero point control signal has been input, , And if the zero point control signal is not inputted, it is possible to judge again whether the weight of the fluid receptacle connected to the fluid set has reached the threshold value.

Meanwhile, if the liquid receiver 100 determines that the weight of the liquid receiver connected to the liquid receiver has reached the threshold value, it may occur by changing the alarm alarm 1 stage to the alarm warning 2 stage (750). In this case, the alarm 2 stage is an alarm warning that the frequency of the alarm becomes higher than that of the alarm 1 stage or the alarm strength becomes larger, and the user can be informed that the needle needs to be immediately removed from the patient's body or the fluid must be replaced .

Further, the liquid receiver 100 may determine whether a zero point control signal is input in a state where the alarm warning 2 is being generated (760). The zero point control signal can be input by the user.

If the fluid analyzer 100 determines that the zero point control signal has not been input, it may generate the second alarm warning until the zero point control signal is input.

On the other hand, if the liquid receiver 100 determines that the zero point control signal has been input, it can terminate the generation of the alarm warning 2 step. In addition, the fluid analyzer 100 can initialize the zero point of the weight according to the zero point control signal, the set threshold value, the weight of the calculated fluid, and the like.

Hereinafter, with reference to FIG. 5, a specific configuration of a liquid receiver according to another embodiment of the present invention can be described.

5, the fluid measurement device 100 may include a weight measuring unit 110, a control unit 120, a memory unit 130, an alarm unit 140, a display unit 150, and an input unit 160 .

The weight measuring unit 110 may measure the weight of the liquid receiver mounted on the liquid receiver 100. A liquid container holder may be provided at the bottom of the liquid analyzer 100, and the weight of the liquid container mounted on the liquid container holder can be measured. The weight measuring unit 110 first measures the weight of the liquid container containing the liquid, recognizes that the liquid set is connected to the liquid container containing the liquid when the weight measured by the user is connected to the liquid container by the liquid container, , The weight can be measured by the weight of the liquid set connected to the liquid container containing the liquid.

In addition, the weight measuring unit 110 can measure the weight connected to the liquid receiver set in the liquid receiver from the time when the control unit 120 determines that the liquid solution is started, in real time according to the setting, or at a predetermined time interval.

This means that as the fluid set is connected and the weight of the fluid container containing the fluid approaches the threshold value which is the sum of the fluid set and the weight of the empty fluid container, the completion time of the fluid administration is approaching. Therefore, if the weight of the liquid container to be measured is close to the threshold value or equal to the threshold value, an alarm warning signal can be generated.

Here, the control unit 120 sets a to set a starting point for generating an alarm signal. When the weight of the liquid container to be measured is equal to the threshold + alpha, To the user.

If the weight of the liquid to be measured is less than or equal to the threshold value, the control unit 120 may cause the alarm to be increased or the frequency to be different because the liquid administration is completed, thereby informing the user that the administration of the liquid is completed .

When the zero point signal is input to the input unit 160, the control unit 120 determines that the liquid administration state is terminated, and can stop the alarm warning, initialize the set threshold value, the calculated weight of the liquid,

The memory unit 130 may store data that classifies the fluid container according to the weight of the fluid container. The specification of the fluid container may include the type of the fluid container and the capacity of the fluid container, and may also store the weight of the fluid according to the capacity of the fluid container. That is, the memory unit 130 may store data classified into the type of the liquid receiver, the capacity of the liquid receiver, and the weight of the liquid depending on the weight of the liquid receiver. Data stored in the memory unit 130 may be modified, deleted, and added as needed.
