Method, device and infusion pump for releasing occlusion pressure in infusion set

Abstract

An infusion apparatus inner blocking pressure release method, an infusion apparatus inner blocking pressure release device and an infusion pump. The infusion apparatus inner blocking pressure release method comprises: identifying whether a running state of an infusion pump is a forward infusion state or not (step 102, step 202); if yes, judging whether blocking pressure generated by blocking liquid in an infusion apparatus is larger than or equal to a pressure alarm threshold value or not (step 104, step 204); if yes, stopping forward infusion, and releasing the blocking liquid in the infusion apparatus (step 106); judging whether the blocking pressure is less than or equal to a pressure release threshold value or not, or whether the released liquid quantity of the blocking liquid is larger than or equal to a liquid release threshold value or not (step 108, step 210); and if yes, stopping releasing the blocking liquid (step 110, step 212). The infusion apparatus inner blocking pressure release method can effectively avoid the damage caused by instant injection of blocking liquid accumulated in a blocking part of an infusion apparatus into a human body, and can increase the infusion safety.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method, device and infusion pump for relieving blockage pressure in an infusion set. Background technique [0002] The infusion pump is an intelligent instrument that can precisely control the infusion speed and volume, and can give an alarm to abnormal conditions such as air bubbles, empty liquid, and blockage of the infusion tube, and automatically cut off the infusion channel. It is often used in situations that require strict control of infusion volume and drug dosage, such as the application of vasopressor drugs, antiarrhythmic drugs, intravenous infusion or intravenous anesthesia for infants, etc. [0003] During the infusion operation, when the infusion set is bent or pressed, it will cause the infusion set to be blocked. If the infusion pump continues to infuse, the liquid inside the infusion set will accumulate and increase due to the flexible material of the ...

AI Technical Summary

Problems solved by technology

For the drugs used clinically by the infusion pump, it is likely to cause physical discomfort when injected into the human body instantly, and the instantaneous injection of a large amount of certain drugs may even bring harm to the patient.
