Description

System of Flushing Performance Evaluation for Fluid Set and Method}

The present application relates to a system and method for objectively evaluating the flushing performance of a flushing device installed in an infusion set.

Flushing means that physiological saline is injected into the infusion line through the Y-port installed in the infusion line while the infusion is administered to the peripheral vein, thereby preventing mixing between drugs and the accumulation of chemical precipitates when various drugs are injected. This is a method to prevent blockage of the infusion line by sediment.

In general, before and after drug injection, physiological saline is injected into the Y-port using a syringe so that the residual drug in the previously injected infusion line is washed out into the patient's vein, thereby minimizing the residual amount of the drug in the infusion line. It minimizes mixing with the drug.

This flushing is very important in minimizing the sedimentation of blood or fibrin back into the infusion line in the infusion line.

In addition to physiological saline, the type of solution used for flushing differs depending on the drug due to chemical compatibility issues between the flushing solution and the drug. have.

In particular, in the case of intravenous drug injection, it is recommended to perform flushing every day, at least every 12 hours to prevent infection and side effects such as thrombophlebitis.

If total parenteral nutrition (TPN), which is a mixture of glucose, amino acids, lipid solutions, and vitamins, is administered instead of general saline injection, flushing is more important because the possibility of obstruction due to sediment generation is high.

However, in the case of performing flushing using a conventional syringe, there are disadvantages as follows.

First, the hospital's financial burden on the cost of using and disposing of syringes has increased since it is necessary to perform flushing at least twice a day for patients receiving infusion prescriptions.

Second, the syringe used for flushing should be discarded, but it was very difficult to solve the problem of safety management of discarded syringes because it occurred to wash and recycle the discarded syringe.

Third, as the use of inexpensive syringes increases due to the burden of using syringes, there is a problem of infection of patients, such as cases of receiving fluids and group infection of hepatitis C.

Fourth, in the process of using a syringe, medical personnel's needle-punching (cut) accidents were very frequent, causing considerable inconvenience for medical personnel.

Fifth, it took some time, such as preparing a syringe and a solution for flushing, causing inconvenience to medical personnel.

In order to solve the problem of the conventional method of flushing using a syringe, a flushing device has been developed that can be installed in the infusion line to prevent blockage of the infusion line without using a syringe.

However, since there is no method for evaluating the performance of the flushing device, it is difficult to know how much force should be flushed from the viewpoint of using it. Therefore, the evaluation system that presents the usage criteria by objectively evaluating the performance of the flushing device The demand for it has been demanded.

1. No. 1 Example Infusion set Flushing Performance evaluation system

Referring to FIG. 1, a system for evaluating an infusion set flushing performance according to a first embodiment of the present application will be described in detail.

1 is a schematic diagram illustrating a system for evaluating an infusion set flushing performance according to a first embodiment of the present application.

Referring to FIG. 1, in the first embodiment, the infusion set flushing performance evaluation system includes an infusion bag 110, an infusion line 120, a flushing device 130, a pressure sensor connection 140, a pressure sensor 150, and a performance evaluation. And a device 200 and a slider 300.

The infusion bag 110 is provided with a space for storing fluid therein, and may be formed of a PVC (Poly Vinyl Chloride) material, but is not limited thereto and is provided with a glass material to provide a space in which fluid can be stored. Anything can be applied if there is one.

One end of the infusion line 120 is connected in fluid communication with the infusion bag 110 and the other end of the infusion line 120 is connected in fluid communication with the pressure sensor connection part 140. Accordingly, the fluid stored in the infusion bag 110 may be transferred to the pressure sensor connection part 140 along the infusion line 120.

The flushing device 130 is a part installed in the infusion line 120 to perform flushing. Specifically, the flushing device 130 includes a main body 131, a fixed roller 132, and a driving roller 133.

The main body 131 is provided to surround the infusion line 120, and the upper and lower portions are open.

The fixed roller 132 is installed on one side of the upper portion of the main body 131 and may be provided in the form of a disc, and a plurality of teeth may be formed at regular intervals along the circumference of the disc.

The driving roller 133 is installed inside the main body 131 in a direction facing the fixed roller 132 with the fluid line 120 as the center, and may be provided in the form of a disk like the fixed roller 132, and On the side surface, a plurality of teeth may be formed at regular intervals along the circumference thereof.

The driving roller 133 is installed on the main body 131 so as to be movable in the vertical direction, unlike the fixed roller 132 fixed at the installation position. Specifically, the distance between the fixed roller 132 and the driving roller 133 is a first position (Fig. 2-(b)) that is equal to or greater than the diameter of the infusion line 120 and between the fixed roller 132 and the driving roller 133 The distance of the infusion line 120 is less than the diameter (preferably, the fixed roller 132 and the driving roller 133 are in contact with each other) between the second position (Fig. 2-(a)), it is possible to move up and down. In the first position, the fluid contained in the infusion bag 110 can be transferred to the pressure sensor connection part 140 along the infusion line 120, and in the second position, the fixed roller 132 and the driving roller 133 are connected to the infusion line. When 120 is pressed, a small amount of fluid (preferably, fluid transfer is not possible) can be transferred when the fluid contained in the infusion bag 110 is compared with the case of the first position. Therefore, in general, the driving roller 133 is positioned in the first position so that the fluid contained in the infusion bag 110 flows into the body, and when flushing is required, the driving roller 133 is moved from the first position to the second position. After moving, flushing is performed by holding the main body 131 and moving along the infusion line 120. At this time, the fixed roller 132 and the driving roller 133 rotate with each other while a plurality of teeth formed on the side of the disk are engaged with each other, but the relative position in the body 131 is still fixed, so that the fluid line 120 By moving along, it is possible to continuously pressurize the infusion line 120. The amount of fluid to be flushed increases in proportion to the moving distance of the flushing device 130.

In addition, when the driving roller 133 is moved at a position lower in height than the second position, the amount of fluid transferred along the infusion line 120 may be adjusted according to the movement. For example, the further away from the second position, the more strongly the infusion line 120 is pressed, so that the amount of fluid conveyed along the infusion line 120 may be reduced.

The pressure sensor connection unit 140 has one end connected in fluid communication with the infusion line 120, and the pressure sensor 150 is installed at the other end. The connection part between the pressure sensor connection part 140 and the infusion line 120 is fluid-tight so that the fluid introduced through the infusion line 120 only flows into the inner space of the pressure sensor connection part 140, and similarly, the pressure sensor connection part 140 ) It is preferable that the connection part between the pressure sensor connection part 140 and the pressure sensor 150 is fluid-tight so that the fluid contained in the internal space is not discharged to the outside. A fluid having a predetermined capacity may be stored in the inner space of the pressure sensor connection unit 140.

The pressure sensor 150 is installed on the pressure sensor connection unit 140 and senses the pressure of the fluid accommodated in the pressure sensor connection unit 140.

The slider 300 is installed to surround the fluid line 120 on the upper side of the flushing device 130. One side of the slider 300 is fixed to a pillar on which a moving rail is formed. Accordingly, the slider 300 can slide the flushing device 130 along the infusion line 120 while moving along the moving rail. To this end, the slider 300 is provided with an installation groove 310 that is formed vertically through, and the installation groove 310 is formed through vertically, but one side is penetrated for installation from the side of the infusion line 120 However, the side facing the one side may be provided in a curved shape so as not to penetrate (see FIG. 3). In addition, the slider 300 is connected to a driving motor (not shown) for moving at a constant speed along the moving rail.

The performance evaluation device 200 is electrically connected to the pressure sensor 150 and evaluates the flushing performance of the flushing device 130 using a pressure value sensed by the pressure sensor 150. For example, a device having an operation processing function such as a notebook computer or a desktop PC may be applied.

More specifically, the performance evaluation device 200 may adjust the pressure value sensed by the pressure sensor 150 to a predetermined pressure value (eg, 0) while the pressure sensor connection part 140 is filled with fluid. Therefore, the pressure value itself sensed by the pressure sensor 150 according to the flushing of the flushing device 130 may be evaluated as the performance of the flushing device 130.

In addition, when the pressure value sensed by the pressure sensor 150 exceeds another predetermined pressure value (for example, 2068.59009mmHg (vascular rupture limit value)), it may be evaluated as a non-conforming flushing device 130, and the other device Of course, if it is less than the determined pressure value, it can be evaluated with a suitable flushing device 130.

2. No. 1 Example Infusion set Flushing How to evaluate performance

Referring to FIG. 4, a method for evaluating the infusion set flushing performance according to the first embodiment of the present application will be described in detail.

4 is a flow chart for explaining a method of evaluating an infusion set performance using the system for evaluating an infusion set flushing performance according to the first embodiment.

First, the fluid is filled in the pressure sensor connection part 140 through the adjustment of the flushing device 130. In this state, the performance evaluation apparatus 200 adjusts the pressure value sensed by the pressure sensor 150 to a predetermined pressure value (eg, 0) (S410).

Next, the driving roller 133 of the flushing device 130 is controlled to be positioned at the second position, and the slider 300 moves downward at a constant speed (S420) according to the driving of the driving motor (not shown). As 130 moves along the infusion line 120, flushing is performed (S421).

Next, the calculation unit of the performance evaluation device 200 compares the pressure value detected by the pressure sensor 150 according to the flushing of the flushing device 130 with a predetermined pressure value to evaluate the flushing performance of the flushing device 130 It becomes (S430). When the predetermined pressure value is 0, the pressure value sensed by the pressure sensor 150 itself may be an index showing the performance according to flushing.

3. The second Example Infusion set Flushing Performance evaluation system

With reference to FIG. 5, a system for evaluating an infusion set flushing performance according to a second embodiment of the present application will be described in detail.

5 is a schematic diagram illustrating a system for evaluating an infusion set flushing performance according to a second embodiment of the present application.

5, the second embodiment infusion set flushing performance evaluation system is infusion bag 410, infusion line 420, flushing device 430, pressure sensor connection 440, pressure sensor 450, 3- A way connector 460, a pressure sensing line 470, a fluid injection line 480, a water tank 500, a performance evaluation device 600, and a slider 700.

Since the infusion bag 410, the infusion line 420, the flushing device 430, the pressure sensor connector 440, and the pressure sensor 450 are the same as in the first embodiment, detailed descriptions will be omitted.

Unlike the first embodiment, the second embodiment further includes a 3-way connector 460.

The three-way connector 460 has three connection parts, and an infusion line 420, a pressure sensing line 470, and a fluid injection line 480 are connected to each connection part.

The pressure sensing line 470 is a part that fluidly connects the 3-way connector 460 and the pressure sensor connection part 440.

The fluid injection line 480 is a part for fluid communication between the 3-way connector 460 and the water tank 500.

Valves 421, 471, and 481 are installed in each of the infusion line 420, the pressure sensing line 470, and the fluid injection line 480 to control the fluid flow of each line. The fluid flow in each line can be controlled through manipulation of the valves 421, 471, and 481, and a detailed description thereof will be described later.

The water tank 500 is a part that simulates the peripheral vascular environment, and after closing the first valve 421 installed in the infusion line 420, the pressure value sensed by the pressure sensor 450 corresponds to the blood pressure value of the peripheral blood vessel. A fluid can be injected so as to do so. In the state where the first valve 421 is closed, since the pressure value sensed by the pressure sensor 450 is only due to the water tank 500, the pressure sensor 450 is adjusted while adjusting the amount of fluid injected into the water tank 500. ) Can simulate the peripheral vascular environment. For example, a fluid may be injected into the water tank 500 until a pressure value of 10 mmHg is sensed by the pressure sensor 450.

Second Embodiment The performance evaluation apparatus 600 may evaluate the flushing performance of the flushing apparatus 430 in two ways.

First, it is a method of evaluating the flushing performance based on a pressure change value according to the movement of the flushing device 430 while the third valve 481 is closed. As the flushing device 430 moves, the fluid will be transferred only to the pressure sensor connection unit 440, so performance evaluation similar to that of the first embodiment can be expected.

Second, based on the pressure change value according to the movement of the flushing device 430 with all valves open after injecting fluid into the water tank 500 so that the pressure value of the water tank 500 corresponds to the peripheral blood pressure value This is a method to evaluate the flushing performance. Flushing by the flushing device 430 can be performed in an environment in which the infusion line is actually inserted into the peripheral blood vessel, and there is an advantage of being able to objectively evaluate the performance of the flushing performed on the actual patient.

Like the first embodiment, the performance evaluation device 600 may be electrically connected to the pressure sensor 450, and for example, a device having an operation processing function such as a notebook computer or a desktop PC may be applied.

More specifically, the performance evaluation device 600 includes a pressure value sensed by the pressure sensor 450 while the pressure sensor connection part 440 is filled with fluid or a pressure value sensed while the first valve 421 is closed. If this corresponds to the peripheral blood pressure value, it can be adjusted to a predetermined pressure value (for example, 0), and the pressure value sensed by the pressure sensor 450 itself according to the flushing of the flushing device 430 is flushed. It can be evaluated by the performance of 430.

In addition, when the pressure value sensed by the pressure sensor 450 exceeds another predetermined pressure value (for example, 2068.59009 mmHg (vascular rupture limit value)), it may be evaluated as a non-conforming flushing device 430, and the other device Of course, if it is less than the determined pressure value, it can be evaluated with a suitable flushing device 430.

4-(1). Second Example Infusion set Flushing How to evaluate performance

6 is a flowchart for explaining a method for evaluating an infusion set performance using the system for evaluating an infusion set flushing performance according to a second embodiment.

First, while the third valve 481 is closed by operating the third valve 481, the pressure sensor connection portion 440 is filled with fluid through the operation of the flushing device 430. In this state, the performance evaluation device 600 adjusts the pressure value sensed by the pressure sensor 450 to a predetermined pressure value (eg, 0) (S610).

Next, the driving roller 433 of the flushing device 430 is controlled to be positioned at the second position, and the slider 700 moves downward at a constant speed (S620) according to the driving of the driving motor (not shown). While 430 moves along the infusion line 420, flushing is performed (S621).

Next, the calculation unit of the performance evaluation device 600 compares the pressure value detected by the pressure sensor 450 according to the flushing of the flushing device 430 with a predetermined pressure value to evaluate the flushing performance of the flushing device 430 It becomes (S630). When the predetermined pressure value is 0, the pressure value sensed by the pressure sensor 450 itself may be an index showing the performance according to flushing.

4-(2). Second Example Infusion set Flushing How to evaluate performance

7 is a flow chart illustrating a method of evaluating an infusion set performance different from the evaluation method shown in FIG. 6 using the system for evaluating the infusion set flushing performance of the second embodiment.

First, in a state where the first valve 421 is closed by controlling the first valve 421, the water tank so that the pressure value sensed by the pressure sensor 450 corresponds to the peripheral blood pressure value (eg, 10 mmHg). The fluid is injected into 500 (S710).

Next, the pressure value sensed by the pressure sensor 450 is adjusted to a predetermined pressure value (eg, 0) (S711).

Next, with all the valves 421, 471, 481 open, the drive roller 433 of the flushing device 430 is controlled to be positioned at the second position, and the slider (not shown) is driven by the drive motor (not shown). While 700 moves downward at a constant speed (S720), the flushing device 430 moves along the infusion line 420 to perform flushing (S721).

Next, the calculation unit of the performance evaluation device 600 compares the pressure value detected by the pressure sensor 450 according to the flushing of the flushing device 430 with a predetermined pressure value to evaluate the flushing performance of the flushing device 430 It becomes (S730). When the predetermined pressure value is 0, the pressure value sensed by the pressure sensor 450 itself may be an index showing the performance according to flushing.

According to the present application described above, since the flushing performance of the flushing device can be evaluated and objectified, it is possible to propose a usage standard to medical personnel who use the flushing device.

In addition, by evaluating the flushing performance by simulating an actual human peripheral vascular environment, not simply evaluating the flushing performance, the reliability of the evaluation result is improved.

In addition, the flushing performance can be evaluated regardless of the size of the catheter actually inserted into the patient's blood vessel and the type of flushing device.
