Figure 1 schematically shows a fluid supply auxiliary device according to a first embodiment of the present invention.

Referring to FIG. 1 , the infusion supply auxiliary device according to the first embodiment of the present invention may include a main body 100 , a reaction chamber 130 , a first reactant R1 and a second reactant R2 .

The main body 100 may include an opening 110 having one side opened, through the opening 110 so that the infusion pack 10 can pass through and be seated as will be described later.

When the infusion pack 10 is completely retracted through the opening 110 , it may be in close contact with the seating part 120 provided as a space inside the body 100 .

A reaction chamber 130 may be formed inside the body 100 to surround the seating part 120 .

The reaction chamber 130 has a space, and the first reactant R1 may be filled, and when the first reactant R1 is in a liquid state, the second reactant R2 is floated inside the first reactant R1. ) can be charged. Here, the second reactant R2 may be sealed by the fracture member 140 to be isolated from the first reactant R1 .

The fracture member 140 may be formed of a material that fractures when an external force is applied. That is, the thin film is normally maintained, and when an external force is applied, the fracture member 140 is fractured and the second reactant R2 filled therein escapes to cause a chemical reaction with the first reactant R1. .

The shape of the fracture member 140 may correspond to an outer shape formed by collecting the second reactant R2 and may be formed to surround the outer shape. Here, of course, the second reactant R2 may be divided into a plurality of groups, respectively, and may be arranged in a wide range inside the reaction chamber 130 by spreading them.

In addition, it is preferable that the outer surface of the body 100 is provided with a hard support shell 101 , and the remaining part of the body 100 is formed of a soft material. As will be described later, when the second reactant R2 is discharged from the fracture member 140 while the fracture member 140 is broken by an external force, a reaction gas (R3) generated while chemically reacting with the first reagent R1 This is to allow the pressure by the to be concentrated to the inside of the body 100 .

The first reactant R1 may be, for example, hydrogen peroxide (H ₂ O ₂ ), and the second reactant R2 may be manganese dioxide (MnO ₂ ). In addition, hydrogen peroxide may be a liquid material, and manganese dioxide may be a solid material.

The first reactant R1 charged in the reaction chamber 130 may be at least one compound that chemically reacts with the second reactant R2 to generate oxygen.

According to an embodiment of the present invention, the second reactant R2 used in the reaction chamber 200 may be manganese dioxide, silver, or a mixture thereof.

It is understood that other catalysts that react with hydrogen peroxide may be used in the reaction chamber 130 of the present invention and are within the scope of the present invention. In other words, in this embodiment, hydrogen peroxide and manganese dioxide are described as examples of the first reactant (R1) and the second reactant (R2) charged in the reaction chamber 130, but the second reactant (R2) and chemically reacting If the first reactant R1 is provided and any other reactant is applicable as long as it is a reactant capable of increasing the decomposition rate of the second reactant R2 using the first reactant R1, the present invention is not limited thereto.

In the case of hydrogen peroxide, a typical concentration is 20 volumes, which may mean that when 1 volume of hydrogen peroxide decomposes, 20 volumes of oxygen are produced. At this time, the 20 volume concentration of hydrogen peroxide is equal to 1.67 mol/dm3 (molar concentration) or about 6%. That is, by designing the concentration of hydrogen peroxide or the size of manganese dioxide in advance, it is possible to design an appropriate reaction rate.

As a reaction gas (R3) generated as hydrogen peroxide undergoes a chemical reaction with manganese dioxide in the reaction chamber 130, it may be oxygen (O ₂ ).

Besides hydrogen peroxide, additional compounds may be used depending on the catalyst used.

Figure 2 shows the operating state of Figure 1;

Referring to FIG. 2 , when an external force is applied to the body 100 and the fracture member 140 is fractured, the second reactant R2 filled in the fracture member 140 undergoes a chemical reaction with the first reactant R1. will wake up An expansion pressure is generated in the reaction chamber 130 by the reaction gas R3 generated by this chemical reaction, and this expansion pressure is concentrated inward by the support shell 101 .

Accordingly, since the IV pack 10 seated and fixed on the seating part 120 of the body 100 receives a tightening force from the outside in the radial direction, the IV is discharged from the IV outlet 11 of the IV pack 10 .

The infusion fluid discharged through the fluid outlet 11 may be injected into the body through the cap part (not shown) and a dripping bottle (not shown).

Figure 3 schematically shows a fluid supply auxiliary device according to a second embodiment of the present invention.

Referring to FIG. 3 , the fluid supply auxiliary device according to the second embodiment of the present invention includes a hard support shell 201 having an internal space, an infusion pack 10 , a reaction chamber 202 , an expansion membrane 203 , It may include a first reactant (R1) and a second reactant (R2).

The support shell 201 is formed to be rigid, and as will be described later, when the IV pack 10 disposed in the inner space of the support shell 201 is pressurized by the expansion membrane 203, the pressure applied to the IV pack 10 is tightened. In this way, the infusion stored inside the infusion pack 10 is discharged through the infusion outlet 11 of the infusion pack 10 .

The IV pack 10 is disposed in the inner space of the support shell 201, and the reaction chamber 202 is disposed adjacent to the IV pack 10 in the inner space, the space in which the IV pack 10 is accommodated and the reaction chamber The expansion membrane 203 may be disposed to partition between the spaces in which the 202 is accommodated.

The infusion pack 10 is a bag-type container capable of accommodating an infusion, and a synthetic resin having a thin thickness in a shape including a rectangle having a long side and a short side having a predetermined length, or a round having a predetermined curvature. It can be prepared using a film.

The expansion membrane 203 may be manufactured using a flexible film including polystyrene-based, polyolefin-based, polyurethane-based, polyester-based, and vinyl chloride so that the volume can be changed in a state in which the sap is accommodated therein.

That is, the expansion film 203 is formed to be soft, so that when the reaction gas R3 is generated as described later, it is pushed out with a predetermined elasticity by the expansion pressure.

A first reactant R1 may be filled in the reaction chamber 202 , and the reaction chamber 202 may be filled in a sealed state by the fracture member 210 to be isolated from the first reactant R1 .

Figure 4 shows the operating state of Figure 3;

As shown in FIG. 4 , when the fracture member 210 is fractured due to external force applied from the outside of the reaction chamber 202 , the second reactant R2 filled in the fracture member 210 is mixed with the first reactant R1 and will cause a chemical reaction. An expansion pressure is generated in the reaction chamber 202 by the reaction gas R3 generated by this chemical reaction, and this expansion pressure is concentrated toward the expansion membrane 203 in a direction deflected by the support shell 201 .

For this reason, a pushing force by the expansion film 203 is generated in the infusion pack 10 . The sap stored in the sap pack 10 is discharged through the sap outlet 11 by this pushing force.

The infusion discharged through the infusion outlet 11 may be injected into the human body through the cap unit and the dropper, as in the case of the first embodiment.

Figure 5 schematically shows a fluid supply auxiliary device according to a third embodiment of the present invention.

Referring to FIG. 5 , the fluid supply auxiliary device according to the third embodiment of the present invention includes a main body 300 , a support shell 301 , an infusion pack 10 , a pressure chamber 303 , an expansion membrane 302 , and a reaction chamber. 320 may be included.

The body 300 is formed to have an inner space, and a hard support shell 301 may be formed on the outer surface.

In addition, the infusion pack 10 and the pressure chamber 303 may be provided in the inner space of the main body 300 , respectively.

The infusion pack 10 and the pressure chamber 303 may be partitioned by the expansion membrane 302 in the inner space of the body 300 . Here, the expansion film 302 is formed to be soft and elastically deformed by the expansion pressure when the reaction gas R3 is generated, as will be described later.

The expansion membrane 302 may be manufactured using a flexible film including polystyrene-based, polyolefin-based, polyurethane-based, polyester-based, or vinyl chloride so that the volume can be varied when a supply pressure is provided therein.

On one side of the main body 300 , the pressure chamber 303 communicates with the reaction chamber 320 to receive the supply pressure, and the pressure port 310 is formed, and on the other side of the main body 300 , the fluid for supplying the patient with the fluid. The infusion outlet 11 of the pack 10 may be disposed to penetrate.

The reaction chamber 320 may include a reaction chamber inlet 321 formed to allow the first reactant R1 to be introduced and a reaction chamber outlet 322 formed to communicate with the pressure port 310 .

The second reactant R2 may be accommodated in the reaction chamber 320 . When the first reactant R1 is introduced through the reaction chamber inlet 321 of the reaction chamber 320 , the first reactant R1 is It chemically reacts with the second reactant R2 to form a reaction gas R3.

Since the first reactant R1 and the second reactant R2 have been described in the first embodiment, overlapping descriptions will be omitted.

The first reactant R1 supplied to the reaction chamber 320 may be at least one compound that chemically reacts with the second reactant R2 to generate oxygen.

As hydrogen peroxide is dripped into the reaction chamber 320 as a reaction gas (R3) generated by chemical reaction of hydrogen peroxide with manganese dioxide, oxygen (O ₂ ) may be generated.

In addition to hydrogen peroxide, additional compounds may be used depending on the catalyst used, and the hydrogen peroxide may be introduced into the reaction chamber 320 through the hydrogen peroxide supply line L1 that is controlled and supplied by the first reactant supply unit 330 . Here, the first reactant supply unit 330 may be provided as a piston type pump or an air pump operated by electricity. Of course, when the knot is pulled by the user's hand, water and hydrogen peroxide are discharged into the reaction chamber 200 and mixed with the manganese particles are applied, so that it can be configured to be attached to the arm or leg of the patient.

Substances that generate the reactive gas (R3) can be changed to chemically known substances, and various types of solids instead of powders or liquids can be used to flexibly respond to the manufacturing intentions of the fluid supply auxiliary device according to various patients or facility environments. Materials may be selected.

As the reaction gas R3 generated in the reaction chamber 320, when it is desired to generate oxygen, hydrogen peroxide solution and manganese dioxide may be mixed, and when it is desired to generate nitrogen, sodium azide and iron oxide may be used. .

That is, the reaction gas R3 may be a gas capable of providing pressure through the pressure port 310 of the pressurization chamber 303, and in this embodiment, oxygen is an example, but the gas for this is oxygen or It may be nitrogen or the like, so it is not limited thereto.

A first control valve (not shown) for controlling the pressure received from the reaction chamber 320 may be installed in the pressure port 310 .

The first control valve is for appropriately regulating the supply pressure by the reaction gas R3 formed inside the reaction chamber 320 as will be described later, and the supply amount of the supply pressure is the infusion outlet of the infusion pack 10 ( When the amount of infusion discharged through 11) is exceeded, it is possible to prevent excessive pressure from being applied to the IV pack 10 by downwardly adjusting the opening degree of the first control valve.

On the contrary, when the amount of infusion discharged from the infusion outlet 11 of the IV pack 10 needs to be increased, the opening degree of the first control valve is adjusted upward to apply a higher supply pressure to the IV pack 10 so that the IV fluid is rapidly discharged. It can also promote emissions.

In addition, the infusion outlet 11 allows the infusion of the infusion pack 10 to be discharged to the outside and injected into the patient, and may further include a second control valve (not shown).

As with the operation of the first control valve as described above, the second control valve adjusts the opening degree of the second control valve upward when it is desired to quickly discharge the IV fluid contained in the IV pack 10 , In the case of slowing down the discharge rate of the , a function of downwardly adjusting the opening degree of the second control valve may be performed.

Hereinafter, the operation of the fluid supply auxiliary device according to the third embodiment of the present invention will be described.

6 and 7 show the operation process of FIG.

First, referring to Figure 6, hydrogen peroxide (H ₂ O ₂ ) As an example, 0.192mL and manganese dioxide (MnO ₂ ) powder is prepared.

Then, the reaction chamber outlet 322 of the reaction chamber 320 containing the manganese dioxide is connected to the 200mL pressure port 310, and hydrogen peroxide is added to the reaction chamber inlet 321 side to form oxygen gas through a chemical reaction. .

The oxygen gas formed in the reaction chamber 320 moves to the pressure port 310 through the supply pressure line L2, and as the internal pressure of the pressure chamber 303 increases, the expansion membrane 302 expands and the IV pack 10 ), the received sap is discharged by applying pressure.

In other words, when the internal pressure of the pressure chamber 303 is increased by the oxygen gas generated as described above, the expansion membrane 302 exerts a pushing force by the pressure of the reaction gas R3 as shown in FIG. 7 . will receive At the same time, the expansion membrane 302 pushes the IV pack 10 due to the internal pressure of the pressurization chamber 303 , and the IV pack 10 is positioned between the expansion membrane 302 and the support shell 301 of the body 300 . It is in a state in which the sap can be discharged to the outside through the sap outlet 11 by receiving a tightening force.

The infusion fluid discharged through the fluid outlet 11 may be injected into the body through the cap part and the dropper.

Hydrogen peroxide and manganese dioxide can react according to the user's control or design, so that the fluid is discharged by pressing the filled area of the fluid filled in the infusion pack (10).

That is, even if the internal pressure of the infusion pack 10 is rapidly increased at a fast reaction rate, an appropriate infusion discharge rate can be adjusted by adjusting the respective opening degrees of the first control valve or the second control valve.

In addition, by controlling the particle size (specific surface area, shape, size) and amount of manganese dioxide, it is possible to control the rate of chemical reaction in the reaction chamber 320 and the rate of injection of the solution.

As described above, the fluid supply auxiliary device according to an embodiment of the present invention is made so that the fluid is introduced by gravity as in the prior art. Safety accidents such as patient falls and abrasions can be prevented.
