Problems solved by technology

At the same time, the larger the sample size, the greater the chance of repeating the procedure, the amount of separated plasma decreases after repeating the procedure, and sometimes even the plasma cannot be separated.

Embodiment Construction

[0015] In the present invention, after the whole blood viscosity is completed in the traditional detection process, the step of plasma viscosity detection is optimized so that after the hematocrit (HCT) is completed, the hematocrit tube (HCT tube) is directly placed on the plasma viscosity disk to perform plasma viscosity detection. detection steps (such as figure 1 shown).

[0016] Please combine figure 2 As shown, since the height of the known HCT tube is about 120 mm, if the known HCT tube is used, the operation of the aspirating needle on the plasma viscosity disc will be affected. Therefore, to realize the hemorheology batch detection method of the present invention, it is necessary to reduce the height of the HCT tube to 104 mm, and a sleeve is provided in the test tube hole of the plasma viscosity disc, and the HCT tube 1 that has detected the hematocrit is inserted into the sleeve 2 Plasma viscosity was measured on a plasma viscosity disc.

[0017] The manual steps...

Abstract

The invention relates to an optimized hemorheological batch detection method. The method includes the following steps that: a part of whole blood is absorbed and taken into an improved red blood cellspecific volume tube, and is subjected to centrifugation, so that the specific volume of the red bloods of the whole blood can be detected, the whole blood viscosity of the remaining whole blood is detected; and the plasma viscosity of plasma which has been subjected to red blood cell specific volume detection is directly detected. With the method of the invention adopted, a hemorheological batchdetection process is optimized; the appearance of the red blood cell specific volume tube is improved; manual operation steps are reduced; overall completion time is shortened; efficiency is improved;and work intensity can be reduced.

Description

technical field [0001] The invention belongs to the field of medical detection and relates to an optimized blood rheological batch detection method. Background technique [0002] Blood rheology testing is one of the routine items in the laboratory. Manual operations account for a large proportion of the entire process, mainly composed of whole blood viscosity, plasma viscosity, erythrocyte sedimentation rate (ESR) and hematocrit (HCT) and other testing indicators. [0003] The traditional detection process is to draw whole blood and place it in a hematocrit tube (HCT tube) for centrifugation to detect HCT first, then measure the viscosity of the whole blood with the rest of the whole blood, and then centrifuge to measure the viscosity of plasma. The plasma viscosity of the next process can only be tested after the last sample is completed or the whole blood viscosity of the suspicious sample is repeated, which will undoubtedly increase the overall completion time (TAT).
