When the infusion pump loads woven hose, the first and second signal processing circuits are respectively by bearing that two pressure sensors feed back
Controller is sent to after carrying pressure signal treatment, controller reads and compares two pressure signals, if a certain pressure value is beyond predetermined
Value scope, controller instructs the corresponding signal processing circuit of the pressure value to carry out zeroing treatment, pressure value is adjusted to predetermined value;
After zeroing, controller instructs mechanism of closing the door to shut pump door;
Shut pump behind the door, whether just the automatic liquid-stopping is pressed from both sides for verifying lower pressure sensor with secondary signal process circuit
Often work;During checking, controller first closes automatic liquid-stopping folder, and instructs the infusion pump pump housing mechanism to run some cycles, then reads
Pressure value is removed, if lower pressure value is risen in predetermined range, then its normal work opens automatic liquid-stopping folder again, enters
The normal transfusion of row.
It is preferred that upper pressure sensor is located at the upstream and downstream of infusion pump pump housing mechanism with lower pressure sensor respectively, respectively
Detection pump housing mechanism's upstream pressure and downstream pressure.
It is preferred that lower pressure sensor is located between pump housing mechanism and automatic liquid-stopping folder.
It is preferred that the infusion pump is additionally provided with alarm, there is abnormal alarm with checking for failure of returning to zero.
Using above-mentioned technical proposal, the present invention can automatically carry out pressure circuit zeroing and checking pressure before transfusion is started
Whether detection is working properly, so that the pressure measxurement during ensureing Subsequent infusions is accurate, and then it is defeated to ensure that patient uses
The safety of liquid pump treatment.
