Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

Fig. 1 shows a configuration diagram of an apparatus for calculating the remaining amount of fluid according to an embodiment of the present invention.

1, the apparatus for calculating the remaining amount of liquid 100 includes a speed measuring unit 120, a fluid amount calculating unit 140, a storing unit 160, and a remaining amount calculating unit 180.

The speed measuring unit 120 measures the rate of administration per drop of the liquid. The speed measuring unit 120 may include an infrared ray sensor, and the rate of administration of the infusion solution per drop can be measured by checking the number of droplets of the liquid dropping into the induction tube by using infrared rays. Here, the rate of administration of the sap is the number of drops per minute (drop / min), and the unit of gut (gtt) can be used. The rate of administration per drop of the sap is such that when the drop of the second drop drops 10 seconds after the drop of the first drop, for example, the drop of the second drop falls by 6 drops per minute Therefore, the speed measuring unit 120 can measure the infusion rate of the second droplet by 6 gtt. If the solution of the third droplet drops after 5 seconds from the drop of the solution of the second droplet, the third droplet may fall by 12 per minute. Therefore, the speed measuring unit 120 measures the rate of the solution dispensed with respect to the third droplet 12 gtt.

The fluid amount calculation unit 140 may calculate the fluid amount information per drop by calculating the fluid amount correction value corresponding to the infusion rate per unit volume of the fluid measured by the speed measurement unit 120. [ Here, the correction value for the amount of fluid is a value for compensating for the error of the amount of fluid per drop which varies depending on the rate of application of the fluid, and can be used to more accurately detect the amount of fluid per drop actually dropped depending on the rate of application of the fluid. For example, if the standard amount of the liquid is 0.05 ml, and if the amount of liquid dropped by one drop is 0.051 ml, the correction amount of the liquid amount may be 0.001 ml.

Hereinafter, the operation of calculating the amount of fluid per drop and calculating the remaining amount of fluid according to an embodiment of the present invention will be described in more detail.

The fluid amount calculation unit 140 calculates a fluid amount corresponding to the infusion rate per one drop of the fluid measured by the velocity measurement unit 120 using the fluid amount correction value per drop corresponding to the infusion rate of the fluid stored in the storage unit 160 The correction value can be obtained.

FIG. 2 is a graph showing a correction value of a fluid amount according to the infusion rate of the fluid. As shown in FIG. 2, the fluid amount correction value calculated in advance through an experiment may be stored in the storage unit 160 for each infusion rate of the fluid. It goes without saying that the storage unit 160 may store a variety of fluid amount correction values corresponding to the type of fluid or the type of fluid set.

In this way, the fluid amount calculation unit 140 can extract the fluid amount correction value corresponding to the infusion rate per one drop of the infusion liquid by using the infusion volume correction value table per drop according to the infusion rate of the infusion liquid stored in the storage unit 160 And it is possible to calculate the amount-of-receipt information per drop by using the extracted amount-of-receipt correction value. The amount of liquid per drop can be calculated by substituting the correction amount of the liquid amount in the [Equation 1] below.

[Equation 1]

Amount of fluid per drop ≒ Predefined reference fluid volume + fluid volume correction value C (gtt)

Here, the predetermined reference liquid amount is the amount of liquid amount calculated according to the information displayed on the liquid set, for example, when the information displayed on the liquid set is 1 ml? 20 drops, the standard liquid amount per drop may be 0.05 ml.

That is, the fluid amount calculation unit 140 may calculate the amount of fluid amount per drop that actually drops according to the infusion rate of the fluid by applying the fluid amount correction value according to the infusion rate of the fluid to the reference fluid amount.

FIG. 3 is a table and a graph showing the amount of the liquid depending on the administration rate of the liquid. Referring to FIG. 3, the amount of the liquid per one drop decreases as the administration rate of the liquid decreases, Is large. In addition, since the difference in weight before and after the administration of the liquid is significantly different depending on the administration rate of the liquid, it can be understood that a process of considering the administration rate of the liquid is necessary in calculating the amount of the liquid.

The remaining amount calculating unit 180 can calculate the remaining amount of the liquid using the liquid amount information per drop.

The remaining amount calculating unit 180 calculates the amount of infusion by accumulating the infusion amount information per drop. More specifically, the infusion amount is calculated by adding all the infusion amount information corresponding to each infusion amount, and subtracting the infusion amount from the predetermined infusion amount The remaining amount of the liquid can be calculated. For example, if the fluid amount information per each drop is 1 ml, 2 ml, 0.5 ml, 1 ml, 3 ml, 1.5 ml, 1 ml, it can be calculated that the injection amount is 10 ml, Ml, the remaining amount calculating unit 180 can calculate that the remaining amount of the liquid is 10 ml by subtracting 10 ml from 20 ml.

The operation of calculating the amount of fluid per drop and calculating the remaining amount of fluid according to another embodiment of the present invention will be described in more detail.

The fluid amount calculation unit 140 may calculate the average administration rate by dividing the administration rate per drop of the sap measured by the rate measurement unit 120 and dividing the administration rate by the number of accumulated droplets. For example, when the administration rates per one drop of the sap are 5 gtt, 12 gtt, 15 gtt, and 8 gtt, the fluid amount calculation unit 140 calculates 5 + 12 + 15 + 8 (cumulative dose rate) / 4 10 gtt (average dose rate) can be calculated.

The fluid amount calculation unit 140 can obtain the fluid amount correction value corresponding to the average administration rate calculated using the fluid amount correction value table per drop according to the infusion rate of the fluid stored in the storage unit 160. [ Here, the fluid amount correction value is an average fluid amount correction value corresponding to the average administration rate, and the average fluid amount information per drop can be calculated using the average fluid amount correction value. That is, the fluid amount calculation section 140 can calculate the average fluid amount information per drop by adding the average fluid amount correction value to the predetermined reference fluid amount, as in [Expression 1].

The remaining amount calculating unit 180 may calculate the remaining amount of the liquid by multiplying the average liquid amount information per droplet by the number of accumulated droplets to calculate the injection amount and then subtracting the injection amount from the predetermined liquid amount. For example, if the average fluid amount information is 1 ml, it can be calculated that the injection amount is 7 ml by multiplying 1 ml by 7, which is the cumulative number of droplets. If the fluid amount is 20 ml, It can be calculated that the remaining amount of the liquid is 13 ml.

FIG. 4 shows a graph showing the remaining amount of the liquid depending on the time of administration of the liquid.

Referring to FIG. 4, the graph P1 is a graph of the remaining amount of the fluid according to the embodiment of the present invention. The graph P2 is a graph of the remaining amount of the fluid according to the prior art. The point A in the graph P1 is compared with the actual measurement value B From the viewpoint of comparing point C and point B in the P2 graph, the amount of the liquid administered according to the embodiment of the present invention is about 0.93 ml, A difference of approximately 30 ml may occur. In addition, although the P1 graph does not differ from the actual administration time at the time when the administration is completed, it can be seen that the administration time of the P2 graph is greatly different from the actual administration time.

Hereinafter, a process of calculating the remaining amount of the liquid according to the embodiment of the present invention will be described.

5 is a flowchart illustrating an operation of calculating the remaining amount of fluid according to an embodiment of the present invention.

Referring to FIG. 5, the administration rate per drop of the liquid can be measured (S500). The speed measuring unit 120 for measuring the rate of infusion of the infusion liquid may include an infrared ray sensor. The infusion rate may be determined by checking the number of droplets falling into the induction tube using infrared rays, The rate of administration can be measured. For example, if the liquid of the second droplet drops after 10 seconds from the drop of the liquid of the first droplet, the number of drops of the second droplet may fall by 6 per minute, so that the rate of administration of the liquid with respect to the second droplet can be measured at 6 gtt. If the solution of the third droplet drops after 5 seconds from the drop of the solution of the second droplet, the number of drops of the third droplet may drop by 12 per minute. Therefore, the rate of application of the solution to the third droplet can be measured to be 12 gtt.

Next, the fluid amount correction value corresponding to the infusion rate per one drop of the measured fluid may be obtained (S510), and the fluid amount information per one drop may be calculated (S520). Here, the correction value for the amount of fluid is a value for compensating for the error of the amount of fluid per drop which varies depending on the rate of application of the fluid, and can be used to more accurately detect the amount of fluid per drop actually dropped depending on the rate of application of the fluid.

More specifically, it is possible to obtain a fluid amount correction value corresponding to the infusion rate per one drop of the fluid measured using the fluid amount correction value table per drop according to the predetermined infusion rate of the infusion fluid, and use the obtained fluid amount correction value So that the amount of fluid per drop can be calculated. The amount of liquid per drop can be calculated by substituting the correction amount of the liquid amount in the [Equation 1] below.

[Equation 1]

Amount of fluid per drop ≒ Predefined reference fluid volume + fluid volume correction value C (gtt)

Here, the predetermined reference liquid amount is the amount of liquid amount calculated according to the information displayed on the liquid set, for example, when the information displayed on the liquid set is 1 ml? 20 drops, the standard liquid amount per drop may be 0.05 ml.

That is, it is possible to calculate the amount of the fluid amount per drop actually dropped according to the rate of the infusion by applying the correction amount of the fluid amount according to the infusion rate of the fluid to the reference fluid amount.

Then, the remaining amount of the liquid can be calculated using the liquid amount information per drop (S530).

The amount of infusion per unit volume calculated in step S520 is accumulated to calculate the infusion volume. More specifically, the infusion volume is calculated by adding all the infusion volume information per drop corresponding to each of them, and the infusion volume is subtracted from the predetermined infusion volume The remaining amount of the liquid can be calculated. For example, if the fluid amount information per each drop is 1 ml, 2 ml, 0.5 ml, 1 ml, 3 ml, 1.5 ml, 1 ml, it can be calculated that the injection amount is 10 ml, If it is determined as ml, it can be calculated that the remaining amount of the liquid is 10 ml by subtracting 10 ml from 20 ml.

Meanwhile, a process of calculating the amount of fluid per drop and calculating the remaining amount of fluid according to another embodiment of the present invention is as follows.

The average rate of administration can be calculated by accumulating the administration rate per drop of the sap measured by the rate measurement unit 120 and then dividing by the number of accumulated droplets. For example, 5 + 12 + 15 + 8 (cumulative dose rate) / 4 (cumulative number of droplets) = 10 gtt (average dose rate) when the infusion rate per drop of the sap is 5 gtt, 12 gtt, 15 gtt, Can be calculated.

Then, the fluid amount correction value corresponding to the average administration rate calculated using the fluid amount correction value table per one drop according to the predetermined infusion rate of the infusion solution can be obtained. Here, the fluid amount correction value is an average fluid amount correction value corresponding to the average administration rate, and the average fluid amount information per drop can be calculated using the average fluid amount correction value. That is, the average amount of liquid amount information per drop can be calculated by adding the average liquid amount correction value to the predetermined reference liquid amount, as in [Expression 1].

Next, the remaining amount of the liquid can be calculated by multiplying the average liquid amount information per droplet by the number of accumulated droplets to calculate the injection amount, and subtracting the injection amount from the predetermined liquid amount. For example, if the average fluid amount information is 1 ml, it can be calculated that the injection amount is 7 ml by multiplying 1 ml by 7, which is the cumulative number of droplets. If the fluid amount is 20 ml, It can be calculated that the remaining amount of the liquid is 13 ml.
