Problems solved by technology

[0003] This function has certain limitations, that is, the patient will only deactivate when the blood concentration maintained by the continuous volume infusion rate of the electronic infusion pump is not enough to suppress pain
If the infusion rate of the initial continuous infusion volume is set too high, the blood drug concentration will exceed the pain-inhibiting level, which may cause excessive analgesia, which may cause infusion reactions in patients, and in severe cases, life-threatening

Embodiment Construction

[0023] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0024] The self-controlled analgesic pump control method disclosed here can be applied to the pain treatment and recovery of patients after surgery, cancer patients, childbirth, etc., so as to relieve the analgesic symptoms of patients. Now, this method will be described with a specific embodiment. The infusion bag that stores the infusion is connected to the self-controlled analgesic pump. The capacity of the infusion bag is 150 milliliters, and the doctor sets it according to the patient's condition and the drug concentration in the infusion. The continuous volume infusion rate was 2.0 mL / hour, and the continuous volume infusion rate was decreased linearly at a rate of 0.05 mL / hour. When the infusion rate of the continuous amount is reduced to 1.0 ml / hour, it is not enough to relieve the pain of the patient. At this time, the patient triggers the corr...

Abstract

The invention discloses a patient-controlled analgesia pump and a control method thereof. The method comprises the following steps: setting an infusion speed with a continuous amount as a first speed, and starting infusion at the first speed; reducing the infusion speed with the continuous amount from the first speed; when external trigger information is received, performing infusion for a single-time infusion amount, and increasing the infusion speed with the continuous amount to a second speed which is faster than the infusion speed with the continuous amount when the external trigger information is received; reducing the infusion speed with the continuous amount from the second speed until the external trigger information is received. The patient-controlled analgesia pump provided by the invention reduces excessive analgesia by continuously reducing the infusion speed with the continuous amount, thereby not endangering the life and health of a patient.

Description

technical field [0001] The invention relates to a self-controlled analgesic pump and a control method thereof. Background technique [0002] The self-controlled analgesic pump is an infusion pump used to infuse analgesic drugs. It has the function of patient-controlled analgesia. When the patient feels pain, the patient activates the self-controlled analgesic pump to achieve a single infusion infusion, which is used to relieve pain. Insufficient analgesia due to individual differences. [0003] This function has certain limitations, that is, the patient will only deactivate when the blood concentration maintained by the continuous volume infusion rate of the electronic infusion pump is not enough to suppress pain. If the infusion rate of the initial continuous infusion volume is set too high, the blood drug concentration will exceed the pain-inhibiting level, which may cause excessive analgesia, which may cause infusion reactions in patients, and in severe cases, life-threa...
