Problems solved by technology

However, the existing blood leakage detection device does not judge whether the detected blood leakage in the pipeline is a false detection caused by air bubbles in the pipeline or a real blood leakage phenomenon in the pipeline, which brings inconvenience to the use of the blood purification device.

Embodiment Construction

[0049] The blood leakage detection device of the present invention is used to detect whether there is blood leakage in the pipeline of the blood purification device. Specifically, the visible light emitted by the light emitting device is used to detect the blood leakage of the pipeline. Since oxyhemoglobin (HbO2) has three characteristic absorption peaks in the visible light wavelength range, namely 400nm to 600nm, the peaks are respectively at 415nm, 541nm, and 576nm. When oxyhemoglobin turns into carbon monoxide hemoglobin (HbCO), the spectrum changes. That is, three characteristic absorption peaks appear at wavelengths of 419nm, 540nm, and 569nm. Therefore, the present invention utilizes this principle to detect the blood leakage in the pipeline.

[0050] However, once air bubbles appear in the pipeline, it will affect the detection results of blood leakage. In order to avoid the influence of air bubbles on the detection results of blood leakage, the present invention also ...

Abstract

The invention discloses a blood leak detection method, a blood leak detection apparatus and a computer readable storage medium. The blood leak detection method comprises the following steps: receiving an optical detection signal outputted by an optical receiving device; judging whether the optical detection signal is an abnormal signal; if yes, receiving an ultrasonic detection signal outputted by an ultrasonic receiving device, and judging whether there is bubble in the pipeline of the blood leak detection apparatus according to the ultrasonic detection signal; if it is confirmed that there is bubble in the pipeline, a bubble alarm message is sent out; if it is confirmed that there is no bubble in the pipeline, a blood leak alarm message is sent out. The blood leak detection apparatus is arranged with a micro-controller and a memory; and the blood leak detection method is realized when the micro-controller is executing a computer program. The blood leak detection method, the blood leak detection apparatus and the computer readable storage medium are capable of improving accuracy of blood leakage detection.

Description

technical field [0001] The present invention relates to the detection field in the field of blood purification, in particular to a blood leakage detection method for detecting blood leakage from blood purification equipment pipelines, and also to a blood leakage detection device applying the blood leakage detection method and realizing the blood leakage detection method. A computer-readable storage medium for a method. Background technique [0002] Hemoperfusion and hemodialysis are important components of blood purification therapy. Blood purification is to draw the patient's blood out of the body and contact with the adsorbent and dialysate in the blood purification equipment to remove some exogenous or endogenous toxins, and The purified blood is transfused back into the patient's body, so as to achieve the therapeutic purpose of purifying the blood. Blood purification can be used not only to treat drug poisoning, uremia, kidney disease, and immune system disease, but al...
