Multichannel blood viscosity measuring device and measuring method

Abstract

The invention discloses a multichannel blood viscosity measuring device and a measuring method. The measuring device comprises a pressure equalizer and a measuring unit; the measuring unit consists of a plurality of measuring main bodies; the pressure equalizer comprises a positive pressure air pump, a negative pressure air pump, a switching valve, a first on / off air valve, a first pressure sensor and an air storage cabin; the air storage cabin is provide with a first air tap and a plurality of second air taps; the second air taps are respectively connected with one measuring main body; the measuring main bodies consist of liquid suction test needles, sample pipelines, sample valves, pressure cabins, second pressure sensors and second on / off air valves; and the second on / off air valves are connected with the second air taps of the air storage cabin through pipelines. The measurement method provided by the invention is convenient; further, the measurement speed can be effectively improved; and simultaneously, the measurement precision is guaranteed.

Description

technical field [0001] The invention relates to a medical instrument and method, in particular to a multi-channel blood viscosity measuring device. Background technique [0002] Clinically, blood viscosity is the most important and basic rheological property of blood. The measurement of blood viscosity parameters is of great significance for understanding the fluidity of blood and its changing rules under physiological and pathological conditions, and for diagnosing and preventing diseases with abnormal blood viscosity. important meaning. At present, the most accurate and effective measurement method is the pressure sensing method, which reproduces the dynamic stress process when blood flows in the blood vessels of the human body, and the measurement results have more diagnostic value. [0003] The existing measuring device is mainly composed of an air pump, a pressure sensor, a pressure chamber and a test needle. This device can directly and effectively achieve the purpose...

Problems solved by technology

[0003] The existing measuring device is mainly composed of an air pump, a pressure sensor, a pressure chamber and a test needle. This device can directly and effectively achieve the purpose of testing, but it can only detect one sample at a time, and the measurement of each blood sample The time is basically the same, which can basically meet the requirements for the inspection departments of small and medium-sized medical institutions (because the number of blood samples is limited), but for places with a large number of samples such as large medical institutions and physical examination centers, the measurement speed is too slow. Simultaneous measurement by multiple instruments not only consumes a lot of manpower and material resources, but also easily causes excessive deviation of the measured value and affects the measurement accuracy
