Description
Technical field
The utility model relates to blood testing field, particularly a kind of Hemostasis examination instrument.
Background technology
Hospitals at Present adopts thrombelastogram instrument from whole dynamic process to monitor the blood coagulation overall picture of patient usually, utilizes the blood of thrombus elastometer to patient to analyze and then exports thrombelastogram.
Current thrombelastogram instrument main operational principle is the change of one sensor being housed monitor pendency silk torsion by pendency silk upper end, lower end suspends one in midair with cylindrical bowl cover, the right cylinder of bowl cover invades in the cup filling blood sample, cup is contained on thermostatic control plate, thermostatic control plate rotates back and forth with 4 ° of 45' angles and drives cup rotate and affect blood sample, along with the increase of time, the resistance that fibrinous adhesion in blood sample produces is different, thus the power difference of pendency silk is passed to by right cylinder on bowl cover, data variation on reflection sensor is different, thus reach the object detecting blood clotting process.
As shown in Figure 1, the critical piece of existing thrombelastogram instrument has: the heating of automatic regulating thermostatic (37 DEG C) and thermostatic control plate 106; Insert the bowl cover 104 with small cylinder in test cup 105; Test cup 105 is carried on thermostatic control plate 106, the pendency silk 102 can connect the depending cylinder 103 of bowl cover 104, being connected with depending cylinder 103, sensor 101.
Pendency silk 102 upper end connecting sensor 101, lower end connects tapered cylinder 103 and becomes to be integrated.The torsion that the rotation of pendency silk 102 produces can be reflected by sensor 101, tapered cylinder 103 and bowl cover 104 are by mechanical axis hole interference fit, lower end test cup 105 is placed in closely can be come on the thermostatic control plate 106 of back rotation with 4 ° of 45' angles, and the rotational of thermostatic control plate 106 drives test cup 105 to rotate; Blood sample 107 is held in the middle of wall of cup and right cylinder.When blood sample 107 sample is in a liquid state, the carrying out back rotation and can not drive bowl cover 104 with small cylinder of test cup 105, reflect that signal is straight line by sensor 101, when blood sample 107 starts to solidify, resistance is produced because of fibrin adhesion between the right cylinder of test cup 105 and bowl cover 104, the rotation of test cup 105 drives bowl cover 104 to move simultaneously, along with fibrinous increase resistance also constantly increases, described test cup 105 drives the motion of bowl cover 104 also to change thereupon, continue the increase of test along with the time, fibrin will dissolve gradually, resistance also slowly reduces, this signal depicts distinctive thrombelastogram by sensor.
Current thrombelastogram instrument has following defect:
Pendency silk suspention bowl cover is adopted to measure, detect the pulling force received of pendency silk, data variation on reflection sensor is different, make measurement result can because of the difference of wire material of dangling, cause the high material requirements to pendency silk of no test result measuring accuracy higher, also make the price of pendency silk higher, too increase the use cost of user on the other hand.
