Disclosed are methods, materials and devices for approximation of blood volume in a fluid, such as in a biological fluid collected during a surgical procedure. The method and devices may include the use of an RBC flocculant, for example polyDADMAC, and an approximate blood hematocrit from the type of animal blood being evaluated, as well as a calculated RBC packing ratio corresponding to the collection device being used. Also provided is a Blood Indicator Panel (BIP), comprising a series of markings calculated from an observed red blood settlement volume, the average animal blood hematocrit, and a calculated RBC packing ratio “η” value for the collection device. A collection device with a BIP is disclosed. Pediatric (about 200 ml or 250 ml size container), adult human (about 1,000 ml-1,500 ml) and veterinary (about 500 ml-2,500 ml) collection containers are also disclosed, that include a RBC flocculant, for use in approximating blood volume in a fluid.

The utility model discloses a blood sedimentation detection frame belongs to medical detection equipment technical field, include: blood sedimentation tube, rotating base, blood sedimentation observation frame, assembly structure and flatness adjusting structure, the blood sedimentation tube is by transparent test tube and can dismantle and install rubber test tube cap at the top of transparent test tube constitution, the rotating base contains the horizontal setting cylindrical support seat, the upper surface center position of support seat is equipped with the round groove, the round groove is rotated and is installed with the carousel through the bearing, the inside setting of support seat has the drive assembly of drive carousel rotation. The utility model discloses a blood sedimentation detection frame has the following advantages: utilize test tube insertion groove and test tube avoidance groove and can preliminarily position blood sedimentation tube, the cooperation of the inside diameter of clamping cylinder and rubber test tube cap, the sustained elastic compensation of cooperation tension spring, effectively eliminates the angle deviation problem existing in traditional clamping slot type positioning, test tube keeps absolute vertical, ensures the authenticity of red blood cell sedimentation trajectory.

Provided is a blood processing module for an automatic blood viscosity measurement device, and more specifically, a blood processing module for an automatic blood viscosity measurement device which scans blood collection tube information through scan, mixes a blood sample by rotating a blood collection tube 360° to completely prevent an erythrocyte sedimentation phenomenon that may occur during waiting time, and furthermore, can improve accuracy of blood viscosity measurement through uniform mixing of the blood sample by sucking and dispensing blood by using a pipette tip to achieve secondary mixing of blood.
