Embodiment Construction

[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0021] see figure 1 , the infusion pump blocking pressure detection method of the present invention, after the infusion pump is installed with the infusion pipeline, comprises the following steps:

[0022] 101. Connect the pressure sensor to the infusion tube, and start the infusion pump;

[0023] 102. The pressure sensor detects the initial pressure value P of the infusion pipeline 0 and passed to the CPU;

[0024] 103. The pressure sensor detects the real-time pressure value P of the infusion pipeline in real time t and passed to the CPU;

[0025] 104. The CPU calculates the current pressure value P in real time t with the initial pressure value P 0 When the difference is less than the preset pressure alarm threshold M, the infusion pump wor...

Abstract

The invention provides a method for detecting the obstruction pressure of an infusion pump. After an infusion pipeline is arranged on the infusion pump, the method comprises the following steps of: detecting an initial pressure value P0 of the infusion pipeline at first time, wherein the first time is the time of starting the infusion pump; detecting a real-time pressure value Pt of the infusion pipeline at second time, wherein the second time is any time after the infusion pump is started; and calculating a differential value of the real-time pressure value Pt and the initial pressure value P0, and outputting an alarm signal when the differential value is more than or equal to a preset pressure alarm threshold value M. The method can be used for disposable infusion sets made of different materials, and is high in alarm accuracy rate.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a method for detecting obstruction pressure of an infusion pump. Background technique [0002] Traditional disposable infusion sets (hereinafter referred to as infusion sets) are produced with PVC as the main raw material. At present, there are a large number of infusion set manufacturers in my country. Due to different raw materials, production ratios, and production processes, the infusion sets produced by different manufacturers vary greatly in terms of toughness, tube wall thickness, and tube diameter. In the course of clinical use, especially when used with infusion pumps, it is obvious that the pressure required to trigger the infusion pump blockage alarm is different when using infusion sets produced by different manufacturers. That is, under the same pressure, using some infusion sets may False triggering of the "blocking" alarm. In addition, because the elasticity of the...
