Embodiment 1

[0012] Such as figure 1 As shown, the clogging detection device of an electronic infusion pump described in this embodiment includes an operational amplifier circuit for detecting current signals or voltage signals inside the motor, and the operational amplifier circuit is connected to the control single-chip microcomputer, and the control single-chip microcomputer It is used to analyze and judge whether the current signal or voltage signal is abnormal. If it is abnormal, it proves that the electronic infusion pump is blocked.

[0013] The operational amplifier circuit is as follows: one end of the motor M1 is connected to the power supply VDD, the other end is connected to the triode Q1, and a diode D1 is connected in parallel at both ends of the motor M1, and the other end port of the triode Q1 is respectively connected to the resistor R5 and the operational amplifier. Connect to port 3, the other end of resistor R5 is grounded; the other end of triode Q1 is connected to res...

Embodiment 2

[0015] The clogging detection method of the electronic infusion pump described in this embodiment detects the current in the motor and uses a single-chip microcomputer to analyze and judge whether the motor is in a clogged running state or a non-clogged running state. The specific method is to detect the current signal in the motor in real time through the operational amplifier circuit, and then analyze it through the single-chip microcomputer. If there is an abnormality, it will be judged as a blockage immediately.

Abstract

The invention relates to the electronic infusion pump technology field and especially relates to a blocking detection apparatus of an electronic infusion pump. The apparatus comprises an operational amplifier circuit used for detecting a current signal or a voltage signal in a motor. The operational amplifier circuit is connected to a control single-chip microcomputer. The control single-chip microcomputer is used for analyzing and determining whether the current signal or the voltage signal is abnormal. If the current signal or the voltage signal is abnormal, the electronic infusion pump is proved to be blocked. In the blocking detection method of the electronic infusion pump, through detecting the current or the voltage in the motor, the single-chip microcomputer is used to analyze and determine whether the motor is in a blocking operation state or an unblocking operation state. By using the blocking detection apparatus of the electronic infusion pump and the detection method thereof, through real-time monitoring of the current signal and the voltage signal, when the signals are abnormal, an infusion tube can be determined to be blocked; an accuracy degree is high; and reaction is rapid and the apparatus and the method are safe and reliable.

Description

technical field [0001] The invention relates to the technical field of electronic infusion pumps, in particular to an electronic infusion pump blockage detection device and detection method. Background technique [0002] In the prior art, in the technical field of electronic infusion pumps, the safety requirements for their use are very high. At the same time, the device lasts for a long time during use, and it is easy to cause the infusion tube to be oppressed and bent when the patient moves or shifts, causing the infusion tube to be blocked, making the electronic infusion pump unable to infuse normally, and affecting the patient's treatment. Contents of the invention [0003] The object of the present invention is to provide a clogging detection device and detection method of an electronic infusion pump that can accurately and quickly determine whether the electronic infusion pump is in a clogged operation state in order to solve the above-mentioned technical deficiencie...
