Embodiment Construction

[0056] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0057] In one embodiment, such as figure 1 As shown, a method for releasing pressure in an infusion set is provided, which specifically includes:

[0058] Step 102, identify whether the running state of the infusion pump is forward infusion state; if so, go to step 104, otherwise, stop running and issue an error alarm.

[0059] The infusion pump includes a motor and a pump body. After the infusion pump is powered on, the motor rotates to drive the pump body to move, and the infusion pump starts to run. The running state of the infusion pump includes a forward infusion state and a reverse infusion...

Abstract

The invention relates to a method for releasing the locking pressure in an infusion apparatus. The method comprises identifying whether the operation state of an infusion pump is a forward direction infusion state or not; determining whether the blocking pressure generated by the blocking liquid in the infusion apparatus is larger than or equal to a pressure alarm threshold value or not if yes; stopping the forward direction infusion and releasing the blocking liquid in the infusion apparatus if yes; determining whether the blocking pressure is smaller than or equal to the pressure alarm threshold value or not or whether the liquid released by the blocking liquid is larger than or equal to a liquid release threshold value or not; stopping releasing the blocking liquid if yes. According to the method for releasing the locking pressure in the infusion apparatus, the harm to a human body due to the instant injection of the accumulated liquid of the blocking portion of the infusion apparatus can be effectively avoided and the infusion safety is improved. In addition, the invention also provides a device for releasing the locking pressure in the infusion apparatus and the infusion pump.

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 ...
