[0062] Based on the first embodiment above, step S10 of the method for detecting needle blockage in this embodiment specifically includes:

[0063] Step S101: When the delivery pipeline is in an initial state, the initial pressure value of the pipeline is acquired through a pressure sensor.

[0064] It should be noted that the initial state refers to the state when the instrument is powered on without sample addition and cleaning. At this time, the delivery pipeline has an initial pressure value, that is, the initial pressure value of the pipeline. By pre-reading the initial pressure value of the pipeline , to avoid the interference of the detection of the blocked needle state due to the change of the initial pressure value under different environments.

[0065] In the specific implementation, in the initial state, the pipeline pressure value of the pressure sensor located in the infusion pipeline is read, and the pipeline pressure value is recorded through the circuit device,...

Abstract

The invention discloses a needle blocking detection method, device and equipment and a storage medium, and belongs to the technical field of medical instruments. The method comprises the steps of: obtaining a pipeline pressure value collected by a pressure sensor, wherein the pressure sensor is located in a liquid conveying pipeline; comparing the pipeline pressure value with a preset pressure threshold value; determining the blocking state of the needle to be detected on the infusion pipeline according to the comparison result; and collecting an initial pressure value of a pipeline, obtaining a working pressure value detected by a pressure sensor in real time, obtaining a pipeline pressure value through calculation according to the initial pressure value and the working pressure value, obtaining a more accurate pressure value, comparing the pipeline pressure value with two preset pressure threshold values, and determining the blocking state of a needle. The detection and the judgment on the blockage of the needle are comprehensive without omission, and the local blockage and the complete blockage of the needle are effectively detected through the comparison of two threshold values.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a needle blocking detection method, device, equipment and storage medium. Background technique [0002] The current plugging needle detection mainly includes capacitance value detection method and pressure detection method. The capacitance value detection method detects the liquid level by changing the electric voltage before and after the needle touches the liquid. The value detection structure is complex and the steps are cumbersome, and the pressure test method may miss the judgment of complete needle blocking. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose of the present invention is to provide a needle blocking detection method, device, equipment and storage medium, aiming to sol...
