As shown in FIG. 6, when the movable portion 110 moves downward, the membrane 112 is closed, and the sap below the movable portion 110 is maintained at a constant pressure by the membrane 112. It can be compressed, and thus the fluid can be injected into the human body at a constant pressure. That is, when the movable part 110 moves downward, it can be seen as a process of injecting the sap into the human body at a constant pressure.

At this time, the upper portion of the movable portion 110 is continuously filled with the sap as long as the movable portion 110 is moved downward. That is, even when the sap is injected into the human body, the sap is always filled inside the pumping tube 101.

This is because the pressure difference occurs as a closed space from the storage container 10 to the upper portion of the movable part 110, the sap contained in the storage container 10 is moved according to the movement of the movable part 110, regardless of the position, This is because the sap is filled into the upper portion of the movable part 110.

Therefore, when the movable part 110 is moved downward, the sap can be injected into the human body at a constant pressure, and when the movable part 110 is moved up, the sap to be injected at the constant pressure into the human body is the movable part 110. Can be filled down.

That is, according to the sap injection device according to the present invention, the sap is always made in one direction.

Hereinafter, the operation of the infusion device according to the present invention will be described schematically.

First, the storage container 10, the pumping tube 101, the tube 20 including the movable part 110 and the injection part 30, which are integrally manufactured as a single piece, are opened, and the driving part 120 is the pumping tube 101. ) Is combined to wrap and power is applied to fill the sap in the pumping tube (101).

Thereafter, when the injection portion 30 is injected into the human body to inject the sap, the sap can be supplied to the human body at a constant pressure.

7 is a cross-sectional view showing another embodiment of a supply pump according to the present invention.

In the present embodiment, since only the configuration of the movable unit 210 and the driving unit 220 of the supply pump 200 is different from the above embodiment, the description and reference numerals other than the movable unit 210 and the driving unit 220 are described above. The description and reference numerals in the embodiments are used.

Referring to FIG. 7, the supply pump 200 according to the present embodiment includes a movable part 210 that is operated up and down in the pumping tube 101, and a driving part 220 which allows the movable part 210 to operate in the vertical direction. ) Is included.

Therefore, when a current is applied to the coil formed in the driver 220 to form a predetermined magnetic field, the body 221 may be moved up and down by the force of the magnetic field.

For example, when a current is applied only to the first module 221 of the driving unit 220, the body 211 may move to the first module 221, and the first and second modules 221 and 222 may be moved. When a current is applied, the body portion 211 may move faster to the center of the first and second 221 and 222. This is because when the current is applied to a plurality of modules, the strength of the magnetic field is increased so that a large force is applied to the body portion 211 to increase the moving speed.

Therefore, the movable portion 210 may be adjusted in the range and speed at which the body portion 211 is operated according to the manner in which the current is applied to a plurality of modules formed in the drive unit 220.

Preferably, the upper hole 214 is circular, the blocking member 212 may be formed in a larger ball shape than the circular. Then, the upper hole 214 may be well blocked by the blocking member 212.

In addition, the movable part 210 may further include a preventing member 213 to prevent the lower hole 215 from being blocked by the blocking member 212.

Then, the phenomenon in which the blocking member 212 blocks the lower hole 215 when the movable part 210 is moved upward can be prevented, and the sap introduced through the upper hole 214 is lowered in the lower hole ( Through the 215, the lower portion of the movable portion 210 may be filled with sap.

Preferably, the lower hole 215 may be formed in a shape that is not blocked by the blocking member 212. Then, the preventing member 213 is not necessary, the configuration can be simplified.

8 and 9, the driving unit 220 is formed to be separated into two parts, and a hinge part 223 for rotating each of the two parts is formed. Then, the driving unit 220 may not only be easily coupled to surround the pumping tube 101 but also may be easily separated.

In addition, the driving unit 220 is formed to be modularized into a plurality of, such as the first module 221 and the second module 222 in each divided into two parts. Then, as described above, according to the method of applying a current to the coil formed in the plurality of modules, the movable distance and the speed of the movable unit 210 can be precisely controlled.

9 is a view illustrating a first module of the driving unit.

Referring to FIG. 9, the first module 221 includes a body portion 224 constituting a body and a coil portion 225 wound around the body portion 224. Here, the body portion 224 may be made of iron or soft iron, the coil portion 225 may be formed in the body portion 224 a plurality.

Then, the force of the magnetic field generated when the current is applied to the coil unit 225 can be increased, the operation of the movable unit 210 can occur smoothly.
