A blood viscoelasticity monitoring device

Abstract

The invention discloses a monitoring device for a viscoelastic strength of blood. The monitoring device comprises a supporting plate, a detection mechanism, a vibration mechanism and a measuring cup, wherein the detection mechanism is internally provided with a laser transmitter and an angular displacement sensor; a probe is provided with a mirror surface; the vibration mechanism comprises a guide rod, a rotary ring, a driving device, a cup frame and a cup cavity; the measuring cup comprises a cup body, a cup head and a heavy block embedded in the cup head; the detection mechanism is externally sleeved with a rotary bearing; the rotary ring is fastened on the rotary bearing. According to the monitoring device for the viscoelastic strength of the blood, the vibration mechanism is used for carrying out regular vibration on a blood sample in the measuring cup to simulate a physiological environment in which in-vivo thrombi is formed; an optical lever method replaces a traditional electromagnetic measurement method to be used for detecting so that the measurement precision and the flexibility are obviously improved; the device is simple and practical in structure, small in mechanism friction, accurate in probe positioning and high in measurement precision, and can meet the requirements of current clinical blood coagulation detection analyses.

Description

Technical field [0001] The invention relates to the technical field of clinical coagulation analysis, in particular to a blood viscoelasticity monitoring device. Background technique [0002] Coagulation is blood coagulation. It refers to the process of blood changing from a flowing liquid state to a non-flowing gel state. It is an important part of physiological hemostasis. The essence of blood coagulation is that soluble fibrinogen in plasma becomes insoluble fiber. Protein process. [0003] Thromboelastometer is used for clinical examination and is one of the important tools for detecting blood coagulation. With the existing blood viscoelasticity monitoring device, it is not easy to keep the cup head upright when inserted into the cup body, which makes it difficult for the probe to be aligned when inserted into the cup head. It is not conducive to the operation of the cup. In addition, the detection process usually requires specific regular oscillations of the blood sample in t...

Problems solved by technology

[0003] Thromboelastography is used in clinical testing and is one of the important tools for detecting blood coagulation. With the existing blood viscoelasticity monitoring device, it is not easy to keep the cup head upright when it is placed in the cup body, which makes it difficult for the probe to be aligned when inserted into the cup head. Accurate, not conducive to the operation of the cup; In addition, the detection process usually requires specific regular vibration of the blood sample in the measuring cup to simulate the physiological environment of thrombus formation in the body; the electromagnetic measurement method in the traditional monitoring device has low measurement accuracy and sensitivity ; In summary, the existing blood viscoelasticity monitoring device has been unable to meet the needs of today's clinical coagulation detection and analysis
