Whole blood viscosity measuring device

Abstract

The invention relates to the field of medical instruments and particularly relates to a whole blood viscosity measuring device. The upper parts of a first support and a second support are provided with strip-shaped holes. A support rod is movably inserted into the strip-shaped hole. The lower side wall of the support rod in the strip-shaped hole is fixedly connected to a first spring. The other end of the first spring is fixedly connected to the inner wall of the lower end of the strip-shaped hole. A second electromagnet is fixedly installed to the inner wall of the lower end of the second support in the strip-shaped hole. The support rod is sleeved by a first sleeve. A sampling box is connected to the outer side wall of the first sleeve. The sampling box is provided with multiple samplingpin holes. A sampling pin is movably inserted into the sampling pin hole. Blood sample test tube fixing racks are arranged in middles of the first support and the second support. A blood rheology measuring device is installed on a blood rheology device fixing rack. The upper end surface of a base is connected to a hydraulic cylinder fixing rack. The upper end of the hydraulic cylinder fixing rackis fixedly connected to a hydraulic cylinder. The other end of the hydraulic cylinder is fixedly connected to a sampling box clamper. The whole blood viscosity measuring device is easy to operate, produces accurate detection results and has strong practicability.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device for measuring whole blood viscosity. Background technique [0002] Whole blood viscosity is a comprehensive index, which is a comprehensive performance of plasma viscosity, blood cell pressure (ratio), deformability and aggregation ability of red blood cells, rheological properties of platelets and white blood cells, and is a comprehensive expression of blood flow with different flow conditions (shear rate) and The viscosity shown by other conditions, the blood viscosity is high when the shear rate is low, and the viscosity gradually decreases with the gradual increase of the shear rate, and finally tends to a stable value. [0003] Whole blood viscosity refers to the viscosity of a fluid. It is the inverse of flow. The greater the viscosity, the slower the flow; conversely, the faster the flow. The specific viscosity value is directly proportional to the viscosity. The...
