Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0035] The present invention comprises a kind of method for measuring the blood loss in operation, and its steps are:

[0036] S1. Collect the anticoagulated whole blood of the patient, and measure the hemoglobin concentration in the whole blood;

[0037] S2. Take the flushing solution and mix it evenly with the anticoagulated whole blood to obtain at least one reference solution with a preset concentration;

[0038] S3. Determining the reference RGB value of each of the reference solutions;

[0039] S4, measuring the measured RGB value of the mixed solution composed of blood and flushing fluid after the operation;

[0040] S5. Comparing the measured RGB value with the reference RGB value of each reference solution to obtain the measured hemoglobin concentration of the mixed solution;

[0041] S6. The actual measured hemoglobin concentratio...

Abstract

The invention discloses a method for measuring the operative bleeding amount and a measuring card, and belongs to the technical field of medical detection. The strong coloring capability of hemoglobin is utilized, and by comparing the color of a postoperative mixed solution of blood and flushing fluid with the color of a reference solution of the preset concentration, the concentration of the hemoglobin of the mixed solution is evaluated, so that the operative bleeding amount is obtained, and the method has the advantages of being rapid, easy and convenient to implement and accurate.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to a method and a measurement card for measuring surgical bleeding. Background technique [0002] Bleeding is the most common complication of prostate surgery, and the amount of bleeding during surgery is an important concern of both surgeons and patients. [0003] The current method of measuring blood loss during surgery is the cyanide hemoglobin method. Cum: By measuring the hemoglobin concentration in the flushing fluid mixed with blood after the operation, dividing it by the hemoglobin concentration of the patient's anticoagulated whole blood, and multiplying it by the amount of flushing fluid used in the operation, the intraoperative blood loss of the patient is calculated. The hemoglobin concentration of anticoagulated whole blood and the amount of flushing fluid are readily available, so the key to measuring bleeding volume is to measure the hemoglobin concentratio...
