Description
Technical Field
The utility model relates to the technical field of medical coagulation detection equipment, in particular to a thromboelastography instrument.
Background
A thromboelastography is an analyzer for monitoring a blood coagulation process from the whole dynamic process of platelet aggregation, coagulation, fibrinolysis, etc., and is used for monitoring and analyzing the coagulation state of a blood sample, thereby detecting the health state of a human body. According to the number of channels, the channels are generally divided into a single channel, a two channel, a four channel, a six channel, an eight channel and the like. On each channel, a blood sample to be detected is held in a test cup, a cup cover positioned at a detection head is arranged at the lower part of the suspension wire, the center of the cup is automatically lowered and placed in the middle, and the test cup rotates back and forth at an angle of 4 degrees 45' relative to a small cylinder at the lower part of the cup cover. As the time increases, the adhesiveness of fibrinogen in the blood sample changes, the resistance generated by the transmission of the blood sample to the cylinder on the cup cover changes, the force transmitted to the suspension wire through the cup cover changes along with the coagulation process, so the torsion force born by the suspension wire also changes along with the coagulation process, and the data obtained by the angle sensor changes along with the coagulation process, thereby achieving the purpose of detecting the dynamic process of coagulation.
Typically, the sample is collected and stored in a blood collection tube, and the blood collection tube is inverted at least 3-6 times, thoroughly mixed, immediately inspected, and no more than one hour at the latest. During detection, a proper amount of blood sample in the blood collection tube is transferred into a test cup, and the test cup is placed into a thermostatic cup groove at 37 ℃ for subsequent detection.
The blood sample in the blood collection tube is necessary to be subjected to incubation pretreatment at 37 ℃ before being transferred into the test cup, and the specific reason is that the blood sample is rewarmed at room temperature (25 ℃) and incubated at 37 ℃, and the two detection results have certain difference, because the significant thrombin in the coagulation process directly affects the process from the formation to the development of a blood clot, the synthesis of the blood sample is affected by the environmental temperature, the most suitable catalytic temperature of the thrombin is 37 ℃, for example, the pretreatment and the activation of the sample are carried out at room temperature, the sample needs to absorb enough heat after being put on the machine to reach 37 ℃, the time is calculated in R, the rewarming treatment of the sample at room temperature can affect the R value in the TEG parameter, the R value is prolonged, and the accuracy of the detection result is affected. The american blood institute authorities all suggested that the blood samples required incubation pretreatment for incubation at 37 ℃ prior to handling.
However, the current thromboelastography in the market is usually only provided with a test cup thermostat for performing constant temperature incubation on the blood sample under test, and does not perform incubation pretreatment on the sample before the test, which affects the accuracy of the test result. Because thrombi elastography is a sensitive monitoring of the whole blood coagulation process, mainly capturing the tiny changes in the whole blood coagulation process, the tiny changes of external operation can lead to the change of the detection result, thereby affecting the accuracy of the detection result. Therefore, there is a need for improvements in thromboelastography to achieve incubation pretreatment of blood samples.
In addition, the existing thromboelastography instrument is usually leveled by manually rotating three universal wheel legs, so that the requirement on personnel experience is high and the leveling speed is low.
