Problems solved by technology

However, due to the individual differences of patients, the degree of description of pain and the degree of pain tolerance, it is difficult for VAS to reflect the real-time pain of patients; and it is impossible for VRS to be used for a long time due to the influence of patients' vision in clinical application.

Embodiment 1

[0052] The present invention comprises the following devices:

[0053] A setting device for setting the minimum interval between administration of the analgesic PCA pump,

[0054] A device for receiving an on command to start an analgesic PCA pump;

[0055] A judging device for judging an opening command, the judging device includes:

[0056] A device that judges a valid command for the first opening command and subsequent opening commands that are separated by at least the minimum interval time t,

[0057] And the device that judges the opening command as an invalid command within the minimum interval time;

[0058] An actuator for executing effective instructions to turn on the analgesic PCA pump;

[0059] A statistical device for separately counting the number of occurrences of the minimum interval time, the number of invalid instructions and the number of valid instructions in multiple time periods;

[0060] A storage device for correspondingly storing the number of oc...

Abstract

The invention relates to the technical field of analgesia patient controlled analgesia (PCA) pumps, in particular to an analgesia PCA pump based on fuzzy mathematics judgment for pain degree of analgesia. In the field of pain treatment by using the analgesia PCA pump, PCA press information of a patient is delivered through wireless transmitting and receiving. In a computer terminal, due to surgery patient individual differences and psychological and physiological differences of patients, a concept of fuzzy mathematics is introduced, patient-controlled fuzzy analgesia index (PCFAI) is put forward, and an analgesia pump platform is passed through adoption of fuzzy mathematics judgment for pain degree of analgesia. Through the analgesia pump platform, medical staff can monitor pain and analgesia condition of patients in the shortest time and optimize analgesia dosage schedule in time.

Description

[technical field] [0001] The invention relates to an analgesic PCA pump and a method, in particular to an analgesic PCA pump and a method for judging the degree of pain analgesia based on fuzzy mathematics. [Background technique] [0002] Pain is a common symptom of surgical patients, but affected by other factors such as psychology, physiology and drugs, pain will directly affect the recovery of postoperative patients. In clinical practice, how to choose appropriate drugs and doses to achieve effective treatment and control of pain is still a research topic. In recent years, the widespread use of analgesic PCA pumps has alleviated the need for pain control. However, due to the lack of correct assessment of the degree of pain, the pumping time of analgesic drugs is longer, insufficient analgesia or overdose, which damage the health of patients. [0003] Currently commonly used assessments are (1) Verbal Grading Scale (VAS); (2) Visual Analogue Scale (VRS). However, due to ...
