As shown in FIG. 7, the piston member 510 is provided with a permanent magnet 511, and the piston member 510 and the permanent magnet 511 are at least in communication with each other in the longitudinal direction of the cylinder 500. One or more flow paths 512 are formed, and the permanent magnets 511 are arranged to have different polarities in the longitudinal direction of the cylinder 500, that is, the left and right directions.

The diaphragm valve 513 is attached to one side of the piston member 510 to open and close the flow path 512. The diaphragm valve 513 has an intermediate portion of the piston member 510. ) It is fixedly attached and consists of soft material.

Thus, when the piston member 510 moves in the left direction of the cylinder 500 as shown in FIG. 5, the diaphragm-shaped valve 513 is folded by the pressure of the Ringer's fluid flowing through the flow path 512 so that the piston member 510 is moved. 6) and the piston member 510 moves to the right side of the cylinder 500 as shown in FIG. 6, the diaphragm valve is caused by the pressure of Ringer's liquid in the right side of the cylinder 500. 513 is expanded to close the flow path 512.

When the information on the target flow rate and the pump quality interval is read from the memory device, the target flow rate value is alternately applied to the frequency generator 610 for each pump quality interval. For example, when the pumping interval is set in units of 6 seconds, the target flow value is applied to the frequency generator 610 from the setting unit 600 during the first 6 seconds, and then the control of the application of the target flow value is stopped for the next 6 seconds. The operation is repeated. Of course, if the pump quality interval is not set by the user, the target flow rate value from the setting unit 600 is continuously applied to the frequency generator 610.

In addition to setting only the fixed pumping interval according to the data set in the memory device of the setting unit 600, the scanning mode may also set a scanning mode for setting the pumping interval differently for each time. For example, if the mode of injecting Ringer's solution for 1 hour is selected, the pumping interval is determined to be approximately 0.7 seconds, and if the mode of injecting Ringer's solution for 9 hours is selected, the injection mode in which the pumping interval is determined to be approximately 6 seconds may be set. .

Since the corresponding control signal is generated only while the target flow rate value is input from the unit 800, the impeller 720 in the cylinder 700 ejects the ringer liquid at the pumping interval selected by the user.

That is, the user can finely adjust the supply amount of the Ringer's liquid by selecting the supply period of the Ringer's liquid in addition to setting the supply amount of the Ringer's liquid.
