Furthermore, terms including ordinals such as first, second, etc. used in this specification can be used to describe various elements, but the elements should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be referred to as a second component, and similarly, the second component may also be referred to as a first component.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic diagram showing a chemical liquid supply system according to an embodiment of the present invention. 1, the chemical liquid supply system includes a chemical liquid pump 200, a chemical liquid injection valve 300, a hose 400, a syringe 500, and a chemical liquid supply amount adjusting device 100. As shown in FIG.

The chemical liquid injected into the chemical liquid injecting valve 300 in the direction of the arrow does not flow to the chemical liquid supply regulating device 100 but flows to the chemical liquid pump 200 and is stored. That is, the chemical liquid flowing into the chemical liquid pump 200 flows into the chemical liquid storage tube 230 of the elastic material. As the chemical liquid is introduced, the chemical liquid storage tube 230 is inflated and the moving tube 220 and the support disk 240 And moves along the movement axis 210.

Specifically, although not shown in the drawings, the upper end of the moving pipe 220 is fixedly coupled to the supporting plate 240, and the lower end of the moving pipe 220 is cut and clogged on a fixed pipe (not shown). In addition, the moving pipe 220 is formed with an empty space therein so as to move along the moving shaft 210.

On the other hand, the upper end of the chemical solution storage tube 230 is tied to the upper end of the moving tube 220, and the lower end thereof is bound to the lower end of the fixed tube (not shown) such that the chemical solution does not leak to the outside. Therefore, the chemical liquid injected into the chemical liquid injecting valve 300 flows only through the fixing tube (not shown) to the chemical liquid storing tube 230. As the chemical liquid flows, the chemical liquid storing tube 230 of the elastic material is expanded, .

At this time, when the chemical solution storage tube 230 is inflated, the moving tube 220 and the supporting disk 240 are pushed up along the moving shaft 210. In this case, It is possible to know the amount of the drug solution injected through the injection port 250.

The chemical solution stored in the chemical solution storage tube 230 may be supplied to the chemical solution supply controller 100 along the hose 400 by the restoring force of the chemical solution storage tube 230.

For example, when the user adjusts the chemical liquid injection valve 300 so that the chemical liquid does not flow from the chemical liquid pump 200 to the chemical liquid supply amount regulating device 100 and the chemical liquid is injected in the arrow direction, the chemical liquid storage tube 230 is expanded The chemical solution is stored. At this time, a restoring force is applied to the chemical liquid storage tube 230 made of an elastic material, but the chemical liquid can not flow because the path to the chemical liquid supply amount regulating device 100 is blocked. Thereafter, when the user adjusts the liquid injecting valve 300 so that the liquid flows into the liquid supplying device 100 through the liquid pump 200, the stored liquid undergoes the restoring force of the liquid storing tube 230, 100).

For the above operation, the chemical liquid injection valve 300 may include a three-way filter or the like, but is not limited thereto.

On the other hand, when the chemical liquid is introduced into the chemical liquid supply amount adjusting device 100 along the hose 400, the chemical liquid supply amount adjusting device 100 adjusts the chemical liquid supply amount according to the user's operation and supplies a certain amount of chemical liquid to the syringe 500 do. For example, the user can rotate the handle of the chemical liquid supply amount regulating device 100 to adjust the desired chemical liquid supply amount.

Accordingly, the user can precisely control the nutrients or the chemical solution injected into the blood vessel of the patient according to the patient's condition, and can continuously and continuously administer the patient.

Hereinafter, the configuration and the combination of the chemical liquid supply amount regulating apparatus 100 will be described with reference to FIG. 2 and FIG. FIG. 2 is an exploded perspective view of a chemical liquid supply amount adjusting apparatus 100 according to an embodiment of the present invention. FIG. 3 is a perspective view of a chemical liquid supply adjusting apparatus 100 according to an embodiment of the present invention, And FIG.

2, the chemical liquid supply amount adjusting apparatus 100 includes a lower case 10, a fixing member 20, a first leakage preventing member 30, a chemical liquid adjusting unit 40, a second leakage preventing member 50, a cover 60, an upper case 70, and an adjustment member 80, and may be coupled to each other in the order shown.

The means for coupling the respective constituent elements of the chemical liquid supply amount regulating apparatus 100 may be any means capable of being fastened to each other, for example, in the form of an arm or a male, and is not limited to those shown in the drawings. Therefore, the description of the coupling means irrelevant to the essence of the present invention will be omitted.

The fixing member 20 has the fixing protrusions 18-1 to 18-3 provided in the lower case 10 with the fixing grooves 28-1 to 28-3 provided in the bottom surface (Fig. 3 (b) And can be fixedly mounted on the lower case 10.

A central portion 25 having a cylindrical shape recessed inward is formed on the upper surface (Fig. 3A) of the fixing member 20 and a first portion And the engaging pieces 26 are formed in the top surface direction.

3 (d)) of the bottom surface (FIG. 3 (d)) of the medicament solution regulating portion 40, a locking hole 48, which is inserted into the central portion 25 of the fixing member 20 and can be fastened to the first locking piece 26, And is engaged with the fixing member 20 by inserting the locking hole 48 into the center portion 25 of the upper surface of the fixing member 20 and can be rotated in the coupled state.

The cover 60 has second latching pieces 46-1 to 46-4 formed at the center of the upper surface (FIG. 3 (c)) of the medicament control portion 40 and third latching pieces 45-1 To 45-4, and grooves 61-1 to 61-3 are formed on the upper surface to which the adjustment member 80 can be coupled.

The upper case 70 coupled with the lower case 10 is provided with a hole 70 at a position corresponding to the cover 60 in a state where the fixing member 20, the chemical liquid control unit 40, And around the hole 70, a scale indicative of the amount of the liquid is displayed outside.

The adjustment member 80 is fixedly coupled to the grooves 61-1 to 61-3 of the cover 60 through the hole and the chemical solution adjustment portion 40 is rotated as the adjustment member 80 is rotated , The user can confirm the amount of the weak liquid supplied to the injector 500 through the scale of the weak liquid amount.

Hereinafter, the principle of adjusting the supply amount of the chemical solution according to the rotation of the chemical solution regulating part 40 through the concrete structure of the fixing member 20 and the chemical solution regulating part 40 will be described.

For example, as shown in Fig. 3 (a), on the upper surface of the fixing member 20, three chemical liquid inflow holes (hereinafter referred to as " And a chemical liquid discharge hole 24 for discharging the chemical liquid drawn into the chemical liquid inlet holes 21, 22 and 23 can be formed. 3, the chemical solution discharge hole 24 has the largest radius and the radius is small in the order of the first chemical solution inflow hole 21, the third chemical solution inflow hole 23 and the second chemical solution inflow hole 22 However, the present invention is not limited thereto.

Specifically, the chemical liquid inflow pipes 21-1 and 22-2 that are connected to the three hoses 400-1 for introducing three different liquid medicine amounts and guide the respective liquid medicine amounts to the chemical liquid inflow holes 21, 22 and 23, respectively -1, and 23-1 may be formed on the bottom surface of the fixing member 20, and three different amounts of the chemical liquid may flow through the chemical liquid inlet pipes 21-1, 22-1, and 23-1, 21, 22 and 23, respectively.

At this time, capillaries of different diameters may be included in the three hoses 400-1, and the amount of the three chemical fluids introduced into the fixing member 20 can be determined according to the diameter of the capillary. For example, an amount of the reference chemical liquid is drawn into the first chemical liquid inflow hole 21, a chemical liquid amount of twice the reference chemical liquid amount is introduced into the second chemical liquid inflow hole 22, The amount of the chemical liquid which is four times the liquid amount can be introduced.

On the other hand, as shown in FIG. 3 (c), three fluid passages 41, 42 and 43 (see FIG. 3) are selectively connected to the chemical liquid inflow holes 21, Are formed in one circumferential region corresponding to each chemical liquid inflow hole 21, 22, 23.

At this time, on the respective flow paths 41, 42, 43, flow paths 41-1 to 41-4 for introducing the chemical liquid from the chemical liquid inflow holes 21, 22, 23 and guiding them to the respective flow paths 41, 42-1 to 42-4 and 43-1 to 43-4 are formed so that the flow paths 41, 42 and 43 are connected to the chemical liquid inflow holes 21, 22 and 23, respectively, As shown in FIG.

The reason that the flow paths 41, 42 and 43 are selectively connected to the chemical solution inflow holes 21, 22 and 23 is that the chemical solution inflow holes 21, 22 and 23 are selectively The chemical liquid inflow holes 21, 22 and 23 and the flow path holes 41-1 to 41-4, 42-1 to 42-4 and 43-1 to 43-4 are selectively connected to each other, It means that the flow paths 41, 42, and 43 can flow.

For example, the flow path holes 41-1 to 41-4 are formed on the first flow path 41 corresponding to the first chemical liquid inflow hole 21 and the second flow paths 41-1 to 41-4 corresponding to the second chemical liquid inflow hole 22, The flow path holes 43-1 to 43-4 may be formed on the third flow paths corresponding to the flow path holes 42-1 to 42-4 and the third chemical solution inflow hole 23. [ Therefore, the amount of the reference chemical liquid through the first chemical liquid inflow hole 21 and the amount of the chemical liquid twice the standard chemical liquid amount through the second chemical liquid inflow hole 22 are formed in the first flow path 41 and the second flow path 42, Then, the amount of the chemical liquid, which is four times the reference chemical liquid amount through the third chemical liquid inflow hole 23, can flow through the third flow path 43.

The chemical solution regulating portion 40 is provided with a chemical solution discharge port 44 for guiding the chemical solution guided along the selectively connected flow path to the discharge pathway 48 of the bottom surface, And is connected to the chemical liquid discharge port 48 along the line 47. On the other hand, as shown in FIG. 3 (d), in order to guide all the chemical liquid guided through the selected channels 41, 42, 43 to the chemical liquid discharge hole 24, A discharge passage 48 is formed on a circumference corresponding to the position of the chemical solution discharge hole 24. [

The user can selectively open the chemical liquid inflow holes 21, 22, and 23 by rotating the chemical liquid control unit 40 through the structure of the fixing member 20 and the chemical liquid control unit 40 as described above. The supply amount of the chemical liquid supplied to the injector 500 can be adjusted by adjusting the amount of the chemical liquid guided to the chemical liquid discharge hole 24. [

The first leakage preventing member 30 is included between the fixing member 20 and the chemical liquid adjusting unit 40 to prevent the liquid chemical liquid from leaking between the fixing member 20 and the chemical liquid adjusting unit 40 And a second liquid leakage preventing member 50 may be included between the liquid medicament adjusting unit 40 and the cover 60 to prevent the liquid medicine guided to the liquid medicament adjusting unit 40 from being leaked to the outside.

Specifically, the first leakage preventing member 30 is fixed to the center portion 25 of the fixing member 20, the chemical liquid inflow port 30, the first liquid leakage preventing member 30, And includes a hole at a position corresponding to the holes 21, 22 and 23 and the chemical solution outlet hole 24 and can be fixedly coupled to the fixing protrusions 27-1 to 27-7 formed on the upper surface of the fixing member 20 . The second leakage preventing member 50 may also include a hole at the center thereof so as not to interfere with the coupling of the chemical liquid control unit 40 and the cover 60. For this, the first and second leakage preventing members 30 and 50 may be made of silicon, rubber synthetic resin, or the like, but the present invention is not limited thereto.

Although the chemical liquid supply amount adjusting device 100 has been described above as an example of the eight chemical liquid supply amount adjusting devices, the chemical liquid supply amount adjusting device 100 does not necessarily include all of the above-described chemical liquid supply amount adjusting devices. . For example, the chemical liquid supply amount regulating device 100 may be configured without the first leakage preventing member 30 and the second leakage preventing member 50 in the case where there is no problem in leakage of the chemical liquid, 40 and the upper and lower cases 10, 70 and the regulating member 80 by marking a scale on the side of the upper and lower cases 10,

Hereinafter, the operation of the chemical liquid supply amount adjusting apparatus 100 will be described in more detail with reference to FIG. 4 is a planar perspective view in which the chemical liquid regulating portion 40 is coupled to the fixing member 20. [

As described above, the chemical liquid control unit 40 can adjust the amount of the chemical liquid that is guided to the chemical liquid discharge hole 24 according to the adjustment angle, which is combined with the fixing member 20 and rotated about the central axis.

Specifically, the amount of the reference chemical liquid is set in the first chemical liquid inflow hole 21, the amount of the chemical liquid in the second chemical liquid inflow hole 22 is twice the standard liquid liquid amount and the amount of the standard liquid liquid in the third chemical liquid inflow hole 23 When the amount of the chemical liquid is increased by 4 times, the amount of the chemical liquid guided to the chemical liquid discharge hole 24 can be adjusted between 0 and 7 times the standard chemical liquid amount. That is, the chemical liquid supply amount can be adjusted to eight levels.

In the example of FIG. 4, when the liquid amount 1 is set to the first chemical liquid inflow hole 21, the liquid amount 2 is set to the second chemical liquid inflow hole 22, and the liquid amount 4 is introduced to the third chemical liquid inflow hole 23 That is, it is assumed that the reference chemical liquid amount is 1. 4 (a) to 4 (h) show a state in which the amount of the chemical liquid guided to the chemical liquid discharge hole 24 in the chemical liquid inflow holes 21, 22, and 23 is controlled between 0 and 7 Represents an adjustment angle.

4 (a) shows the case where the chemical liquid inflow holes 21, 22, 23 of the fixing member 20 are not connected to any of the flow path holes of the chemical liquid control portion 40, that is, 21, 22, and 23 are all blocked so that the chemical solution is not guided to the flow paths 41, 42, and 43. Therefore, the amount of the weak liquid guided to the chemical liquid discharge hole 24 at the adjustment angle as shown in FIG. 4A becomes zero.

4 (b) shows a case where the chemical liquid regulating portion 40 is rotated by 45 degrees counterclockwise with reference to FIG. 4 (a). In this case, it can be seen that the first chemical liquid inflow hole 21 is connected to the flow path hole 41-1 formed in the first flow path 41, and the remaining chemical liquid inflow holes 22 and 23 are still clogged.

Therefore, only the chemical liquid which has flowed into the first chemical liquid inflow hole 21 flows through the first flow path 41, the> discharge guide path 47, the chemical liquid discharge port 44, the discharge flow path 48, 24. 4 (b), it can be seen that the liquid level 1 indicates the adjustment angle to be guided to the liquid discharge hole 24.

4 (c) shows a case where the chemical liquid regulating portion 40 is rotated 90 degrees counterclockwise with reference to FIG. 4 (a). In this case, the second chemical solution inflow hole 22 is connected to the flow path hole 42-1 formed in the second flow path 42, and the remaining chemical solution inflow holes 21 and 23 are blocked.

Therefore, only the chemical liquid that has flowed into the second chemical liquid inflow hole 22 flows through the second flow path 42, the discharge guide path 47, the chemical liquid discharge port 44, the discharge flow path 48, 24. That is, FIG. 4 (c) shows the adjustment angle at which the weak liquid amount 2 is guided to the chemical liquid discharge hole 24.

On the other hand, FIG. 4 (d) shows a case where the chemical liquid regulating portion 40 is rotated 135 degrees counterclockwise with reference to FIG. 4 (a). The first chemical liquid inflow hole 21 is connected to the flow path hole 41-2 formed in the first flow path 41 and the second chemical liquid inflow hole 22 is connected to the flow path hole 41-2 formed in the second flow path 42. In this case, (42-2), and the remaining chemical liquid inflow hole (23) is blocked.

Therefore, the chemical solution flowing into the first and second chemical solution inflow holes 21 and 22 flows through the first and second flow paths 41 and 42, the discharge guide path 47, the chemical solution discharge port 44, The flow path 48 is guided to the chemical liquid discharge hole 24. That is, FIG. 4 (d) shows the adjustment angle at which the liquid amount 3 is guided to the liquid discharge hole 24.

4 (e) shows a case where the chemical liquid regulating portion 40 is rotated 180 degrees counterclockwise with reference to FIG. 4 (a). In this case, the third chemical liquid inflow hole 23 is connected to the flow path hole 43-1 formed in the third flow path 43, and the remaining chemical liquid inflow holes 21 and 22 are closed.

Therefore, only the chemical liquid that has flowed into the third chemical liquid inflow hole 23 flows through the third flow path 43, the discharge guide path 47, the chemical liquid discharge port 44, the discharge flow path 48, 24. That is, FIG. 4 (e) shows the adjustment angle at which the liquid amount 4 is guided to the chemical liquid discharge hole 24.

4 (f) shows a case where the chemical liquid regulating portion 40 is rotated 225 degrees counterclockwise with reference to FIG. 4 (a). The first chemical liquid inflow hole 21 is connected to the flow path hole 41-3 formed in the first flow path 41 and the third chemical liquid inflow hole 23 is connected to the flow path hole 41-3 formed in the third flow path 43. In this case, (43-2), and the remaining chemical liquid inflow hole (22) is blocked.

Therefore, the chemical solution flowing into the first and third chemical solution inflow holes 21 and 23 flows through the first and third flow paths 41 and 43, the discharge guide path 47, the chemical solution discharge port 44, The flow path 48 is guided to the chemical liquid discharge hole 24. That is, FIG. 4 (f) shows the adjustment angle at which the liquid amount 5 is guided to the chemical liquid discharge hole 24.

On the other hand, FIG. 4 (g) shows a case where the chemical liquid control unit 40 is rotated 270 degrees counterclockwise with reference to FIG. 4 (a). The second chemical liquid inflow hole 22 is connected to the flow path hole 42-3 formed in the second flow path 42 and the third chemical liquid inflow hole 23 is connected to the flow path hole 42 formed in the third flow path 43. In this case, (43-3), and the remaining chemical liquid inflow hole (21) is blocked.

Therefore, the chemical solution flowing into the second and third chemical solution inflow holes 22 and 23 flows through the second flow path and the third flow paths 42 and 43, the discharge guide path 47, the chemical solution discharge port 44, The flow path 48 is guided to the chemical liquid discharge hole 24. That is, FIG. 4 (g) shows the adjustment angle at which the liquid amount 6 is guided to the liquid discharge hole 24.

4 (h) shows a case where the chemical liquid control unit 40 is rotated 315 degrees counterclockwise with reference to FIG. 4 (a). In this case, the first chemical liquid inflow hole 21 is connected to the flow path hole 41-4 formed in the first flow path, and the second chemical liquid inflow hole 22 is connected to the flow path hole 42- 4 and the third chemical liquid inflow hole 23 is connected to the flow path hole 43-4 formed in the third flow path 43 so that all the chemical liquid inflow holes are opened.

Therefore, when the chemical liquid flowing into the first to third chemical liquid inflow holes 21, 22 and 23 flows through the first, second, and third flow paths 41, 42, 43, The chemical liquid discharge port 44, the discharge path 48, and the chemical liquid discharge hole 24 are guided. That is, FIG. 4 (h) shows the adjustment angle at which the liquid amount 7 is guided to the liquid discharge hole 24.

As described above, the liquid level adjusting device 100 controls the amount of the discharged chemical liquid by adjusting the amount of the chemical liquid guided to the chemical liquid discharging hole 24 by selectively opening the chemical liquid inflow holes 21, 22, .

In the above example, three chemical fluids are introduced from three hoses 400-1 which supply three different chemical liquid amounts, and thus the chemical liquid supply amount is controlled in eight steps. However, no. For example, even when four different amounts of the chemical liquid are introduced, the technical idea of the present invention can be extended.

That is, according to another embodiment of the present invention, the chemical liquid supply amount adjusting device 100 includes four chemical liquid inflow holes into which different amounts of chemical liquid are introduced, and a chemical liquid discharge hole for discharging the chemical liquid drawn into the chemical liquid inflow hole. And a chemical liquid adjusting unit coupled to the fixing member to selectively open the chemical liquid inflow hole according to a user operation to adjust the amount of liquid medicine guided to the chemical liquid discharging hole.

In this case, the fixing member 20 may further include a fourth chemical solution inflow hole into which a chemical solution amount of 8 times the reference chemical solution amount is introduced in addition to the three chemical solution inflow holes described above, And a fourth flow path selectively connected to the fourth drug solution inflow hole according to the first drug solution inflow hole. Accordingly, the chemical liquid regulating apparatus 100 will be able to regulate the chemical liquid supply amount between 0 and 15 times the standard liquid amount.

For example, as described above, since the amount of the chemical liquid to be introduced into the hose can be determined according to the diameter of the capillary, four liquids having different capillary diameters can be used to calculate the standard liquid amount and the two-, four-, and eight- The amount of the chemical liquid can be respectively introduced into the four chemical liquid inflow holes. Accordingly, the user can selectively open the four chemical solution inflow holes by operating the chemical solution regulating part 40 to adjust the chemical solution supply amount in step 16.

Assuming that the reference liquid amount is 1, the supply amount of the chemical liquid may be adjusted between 0 and 15. [ At this time, the adjustment angle for adjusting the amount of the weak liquid may be 22.5 degrees, but is not limited thereto.
