In general, the infusion pressure of the fluid must be higher than the patient's blood pressure in order to deliver the fluid to the patient.

Therefore, in the conventional case, a bag (hereinafter, referred to as a "liquid bag") containing the liquid is hung on a hanger or the like so as to be located at a high position where the liquid does not flow back by the blood pressure, The dose of the liquid was adjusted by controlling the diameter of the line.

Since the flow of sap flows depending on the height of the fluid bag, it is necessary to control the flow controller whenever the position of the fluid bag changes, and the flow controller should be always observed.

Such a gravity type liquid supply device is troublesome to manage with a constant injection amount, and thus a liquid injection device using air pressure is disclosed.

That is, a cuff of a genuine material provided so as to airtightly enclose the outside of the infusion bag and the infusion bag, an air bag for inflating the infusion bag by injecting air from the lower side of the infusion bag, a pressure gauge for measuring the pressure of the air bag, A main body for controlling the overall operation of the supply device, such as automatically injecting air while measuring the pressure of the air bag, and a liquid pipe connecting the liquid bag and the injection needle.

The conventional infusion apparatus for infusion of pneumatic fluid as described above pressurizes the infusion bag so as to have a moderately higher pressure than the blood pressure so that the infusion fluid is injected by pushing air into the space of the pressurization chamber by a pump .

Conventionally, a liquid supply device using pneumatic pressure has a structure in which an infusion bag is provided inside a cuff, an air bag is installed so as to be in close contact with the infusion bag, air is injected into the air bag, Respectively.

However, in such a conventional liquid infusion device, since the user must press the pressure injection pump by hand to set the pressure of the air bag to a practicable pressure, and the user must continue pumping to maintain the pressure, And the flow rate of the liquid flow is not constant depending on the pumping speed and strength of the user. As a result, the supply amount of the liquid supplied to the patient under treatment becomes unstable, resulting in a medical problem.

As the material of the cuff is formed of a genuine material, air pressure of 300 mmgh or more flows into the cuff or breakage of the folded portion occurs due to the nature of the genitals during continuous use for a long time, .

In addition, since the control valve which controls the conventional liquid tube has the structure of the valve manually controlled by the user, the user needs to continuously supply the liquid with the proper flow amount while observing the procedure, so that the user is carelessly overloaded , The supply of the liquid is not smooth, and it is not accurate.

Disclosure of the Invention The present invention has been made in order to solve the above problems, and it is an object of the present invention to solve the problem of a gravity-fed liquid supply device which is positioned at a certain height and is injected by gravity, or a hand-operated pumping device which applies pressure by hand And it is an object of the present invention to provide an automatic fluid supply device capable of supplying a fluid at a more convenient and stable pressure and at the same time maintaining the state of equipment including the fluid supply pipe cleanly.

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

FIG. 3 is a partially enlarged vertical sectional view of the present invention, and FIG. 3 (b) is a sectional view of the solenoid valve of the present invention. FIG. Sectional view showing the installation state.

The present invention relates to an automatic sap applicator (100) for injecting a sap into a human body.

The automatic SAP supplying device 100 of the present invention includes a main body 1 for forming an external shape and controlling overall operation as shown in FIG. 1 or 2; An openable and closable hard case 2 provided at one side of the main body 1 and having a housing space therein; A liquid bag 4 which is installed in a receiving space of the hard case 2 and is connected to the liquid tube 3; The infusion bag 4 is connected to the main body 1 through the air injection pipe 5 and the pressure control pipe 6 so as to press the infusion bag 4 through the air injected through the air injection pipe 5. [ An air bag (7) installed in close contact with the air bag (7); (9) for mixing the liquid supplied through the liquid pipe (3) and the gas supplied through the gas pipe (8).

2, a liquid supply tube 10 is provided at one side of the liquid bag 4 to supply the liquid to the inside of the liquid bag 4, and a liquid pipe (not shown) 3 to form a fluid-discharging tube 11 through which fluid is discharged.

As shown in FIG. 1, on the channel of the sap tube 3 extending through the sap tube 9, the sap tube 3 is automatically opened and closed as shown in FIG. 3 (b) A control valve 12 of a solenoid valve structure is provided.

The pressure of the air bag 7 can be easily observed and controlled by a patient, a nurse, a caregiver, or the like, which is displayed on the monitor of the main body 1, which is connected to the air bag 7 and the pressure control pipe 6.

That is, the amount of air to be injected into the air bag 7 through the air injection pipe 5 can be appropriately adjusted according to the pressure displayed on the monitor of the main body 1.

As the main body 1 automatically adjusts the air injection position of the air bag 7, the liquid bag 4 is always controlled to be pressed at a constant pressure, so that the position and height of the liquid bag 4 Regardless of the pressure, a constant flow of fluid is supplied by a constant pressure.

In carrying out the automatic infusion device 100 of the present invention having such a structure and configuration, the conventional supply device first sets the pressure of the air bag to a practicable pressure by pressing the pressure injection pump by hand, The operation procedure is not efficient as the pump is continuously pumped in order to keep the flow rate of the fluid flowing in accordance with the pumping speed and strength of the user and the supply amount of the fluid supplied to the patient under treatment is not constant There has been a problem that medical problems arise.

As the material of the cuff is formed of a genuine material, air pressure of 300 mmgh or more flows into the cuff or breakage of the folded portion occurs due to the nature of the genitals during continuous use for a long time, .

In addition, since the control valve which controls the conventional liquid tube has the structure of the valve manually controlled by the user, the user needs to continuously supply the liquid with the proper flow amount while observing the procedure, so that the user is carelessly overloaded , The supply of the liquid is not smooth, and the amount of liquid is not accurate.

However, since the liquid supply device 100 of the present invention has the structure as described above, the conventional problems as described above can be solved.

That is, as shown in FIG. 1, the infusion bag 4 is connected to the infusion tube 3 and is injected into a patient or an operator. At this time, Is obtained by pressurization.

In this process, first, the infusion pressure of the ideal fluid is set to a pressure higher than the blood pressure through the monitor of the main body 1 and then set.

Here, the setting of the main body 1 is set in a certain range according to the holding pressure of the air bag 7, and when the set value is exceeded, the injection of air is stopped. When the set value is exceeded, (7).

After all the setting is completed as described above, when the liquid supply device 100 of the present invention is operated, the pressure of the air bag 7 is measured by the main body 1 connected to the pressure control pipe 6, The air is injected into the air bag 7 through the air injection pipe 5 by the operation of the main body 1 connected to the air injection pipe 5 when the set value is not satisfied .

3 (a), air in the air bag 7 increases the pressure inside the sealed hard case 2, and the liquid bag 4 installed inside the hard case 2 So as to discharge the liquid.

2 is a perspective view of a cushion of the present invention. As shown in FIG. 2, the cushion of the present invention is constructed of a hard case 2 of a retractable type having a certain strength and having a receiving space therein. It is possible to completely solve the conventional problem that the maintenance cost of the cloth such as the cost of the cloth for repairing the damaged cuff has been incurred.

When the air in the air bag 7 as described above pressurizes the fluid bag 4, the fluid is fed to the fluid pipe 3 by the pressure, and is injected into the patient.

Since the pressure at the time of injection is important, the pressure sensor always monitors the pressure, and the real-time measured pressure is compared with the set value of the main body 1. [

Therefore, the injection of air is controlled by the main body 1 for the pressure of the set value, so that a constant pressure is always applied, and a certain amount of liquid is injected.

As shown in FIG. 1, a control valve 12 is provided on the channel of the liquid-receiving tube 3 extending through the liquid-gas mixing tube 9.

This is because when the installation position of the fluid bag 4 is excessively high or when the fluid bag 4 is contracted by external abnormal pressure, it prevents the fluid from flowing back to the fluid bag 4 side, .

In the present invention, a control valve 12 having a solenoid valve structure that can be automatically opened and closed and capable of controlling the liquid pipe 3 is provided.

Therefore, since the user has to manually control the valve structure by the user, the user is required to continuously supply the liquid with a proper flow amount while the user continues to observe the operation, thereby causing overloading in the user's carelessness, Can be completely eliminated.

Since the automatic fluid dispensing apparatus 100 of the present invention can always supply the fluid at a constant pressure irrespective of the installation height of the fluid bag 4, the gravity fluid supplying device or the gravity fluid supplying device It is possible to solve the problem of the liquid supply device provided with the manual pumping device for applying pressure with the hand, and to supply the liquid with a more convenient, stable and even pressure, The condition can be kept clean, and by this, the liquid is supplied accurately according to the doctor's prescription, and there are various effects in various procedures and treatment of the patient.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be clear to those who have knowledge.
