In practice, the degree of how often a patient presses the presser 4 per unit time reflects the pain level of the patient.
Specifically, the drug injection pump automatically adjusts the drug quantity automatically administered by the patient according to the frequency of the patient pressing the pressing device in the unit time, the judgment is determined according to the drug property of drug administration of the liquid medicine, and the doctor sets the parameters of the drug injection pump. The parameters of the injection pump comprise a unit time, an upper limit value of the times of pressing the pressing device 4 by the patient, a lower limit value of the times of pressing the pressing device 4 by the patient, the amplitude of the medicine quantity which is adjusted upwards each time, the amplitude of the medicine quantity which is adjusted downwards each time, the maximum medicine quantity which is automatically controlled by the patient and the minimum medicine quantity which is automatically controlled by the patient, and the parameters are determined by doctors according to the medicine dosage scheme of the patient, and the unit time can be based on the pressing frequency of 30-60 minutes.
The drug administration judging flow method specifically comprises the following judging conditions:
(1) when the number of times that the drug injection pump receives the pressure of the patient to the pressing device in the judging unit time is larger than the set upper limit value, the drug injection pump automatically adjusts the drug quantity of the self-controlled drug administration of the patient, and the maximum drug quantity does not exceed the maximum drug quantity of the self-controlled drug administration of the patient, wherein the patient still has pain under the existing drug quantity transfusion;
(2) when the number of times that the drug injection pump receives the pressure of the patient to the pressing device in the judging unit time is smaller than the set upper limit value and larger than the set lower limit value, the drug injection pump indicates that the existing drug infusion quantity is suitable for the patient, and the drug injection pump does not need to adjust the drug quantity of the patient for self-control drug administration;
(3) when the number of times that the drug injection pump receives the pressure of the patient to the pressing device in the judging unit time is smaller than the set lower limit value, the current drug liquid infusion amount is larger, the drug injection pump automatically regulates the drug quantity of the self-controlled drug administration of the patient, and the drug quantity minimum value does not exceed the drug quantity minimum of the self-controlled drug administration of the patient.
