In one embodiment of the present invention, the above method of use is applied to a thromboelastometer, supported object, comprising: a rotating shaft; the specific implementation of step 802 includes: the rotation axis is arranged in the blood to be detected, and when the blood to be detected rotates, the rotation axis is driven, namely after the appointed length of the lower end of the rotation axis is immersed in the blood to be detected, the blood container is rotated at a certain speed through the rotating device, the blood container is rotated to drive the blood to be detected to rotate, the blood to be detected is rotated to generate a rotating moment on the rotation axis due to the fact that the blood to be detected has a certain viscosity, the rotation axis rotates under the action of the rotating moment, and the larger the viscosity of the blood to be detected is, the larger the rotating angle of the rotation axis is.
In an embodiment of the present invention, after step 803, further comprising: the rotation axis provides the rotation angle. As mentioned above, since the blood to be measured has a certain viscosity, the rotation of the blood to be measured generates a rotation torque on the rotation shaft, and the rotation shaft rotates under the action of the rotation torque, so that the rotation angle of the rotation shaft is related to the viscosity of the blood to be measured, the thromboelastometer can sense the rotation angle of the rotation shaft through various sensors, form a thromboelastogram according to the rotation angle of the rotation shaft, and obtain an index parameter reflecting the elasticity of the blood to be measured according to the thromboelastogram, or directly convert the rotation angle of the rotation shaft into an index parameter reflecting the elasticity of the blood to be measured.
Taking the thromboelastometer shown in fig. 9 as an example, the method of using the thromboelastometer will be described, and as shown in fig. 10, the method of using the thromboelastometer comprises the following steps:
step 1001: fixedly connecting the rotating shaft with a first supporting component in the bracket;
as shown in fig. 9, the thromboelastometer includes: the rotating shaft 904 and the bracket shown in fig. 6, wherein a first fixed connecting piece 9011 (including a fixed part 90111, a stable platform 90112, and a tip cone 90113) in the connecting assembly 901 is fixed to the first supporting assembly 902, and a jewel bearing 9012 as a second fixed connecting piece is fixed to the second supporting assembly 903, wherein the first fixed connecting piece 9011 is fixed to the first supporting assembly 902 in a fixing manner: the fixing portion 90111 is inserted into an insertion hole 9022 in the first support component 902, the insertion hole 9022 is arranged in a groove 9023 in the concave plane 9021, the stabilizing platform 90112 is attached to the groove 9023, the tip of the tip cone 90113 serving as a connecting portion is connected with the jewel bearing 9012 in a point contact manner, and the fixing portion 90111, the stabilizing platform 90112 and the tip cone 90113 can exist as a whole, that is, a connecting gap does not exist among the fixing portion 90111, the stabilizing platform 90112 and the tip cone 90113. In addition, the rotation shaft 904 is connected to the first supporting member 902 in a flexible manner, and only the rotation shaft 904 needs to be kept vertical, for example: the first supporting component 902 can be arranged in a shape like a Chinese character 'kou', the first fixed connecting piece 9011 is arranged on the inner side of the upper end of the shape like the Chinese character 'kou', the rotating shaft 904 is arranged on the outer side of the lower end of the shape like the Chinese character 'kou', and the second supporting component 903 penetrates through the shape like the Chinese character 'kou' to be connected with the tip of the tip cone 90113 on the first fixed connecting piece 9011 on the inner side of the upper end of the shape like the Chinese.
Step 1002: placing the rotating shaft in the blood to be measured;
in this step, the blood to be measured can be contained in a blood container, and the rotating shaft 904 is driven by a lifter in the thromboelastometer to extend into the blood container under a certain force, so that the rotating shaft 904 with a specified length is immersed in the blood to be measured.
Step 1003: when the blood to be measured rotates, the rotating shaft is driven by the rotating blood to be measured;
after the lower end of the rotating shaft 904 is immersed into the blood to be detected for a specified length, the blood container is rotated at a certain speed through a rotating device in the thrombus elastometer, the blood container rotates to drive the blood to be detected to rotate, the blood to be detected has certain viscosity, the rotation of the blood to be detected generates a rotating moment on the rotating shaft 904, the rotating shaft 904 rotates under the action of the rotating moment, and the larger the viscosity of the blood to be detected is, the larger the rotating angle of the rotating shaft 904 is.
Step 1004: the rotating shaft drives the first support component to rotate around the second support component through the point connection of the connecting component;
because the rotating shaft 904 is fixedly connected with the first supporting component 902, when the rotating shaft 904 rotates, the tip cone 90113 in the first fixed connecting component 9011 fixed by the first supporting component 902 rotates around the jewel bearing 9012 through a connecting point with the jewel bearing 9012 at the same angle with the rotating shaft 904, the second supporting component 903 supports the rotating shaft 904 and the first supporting component 902 through the jewel bearing 9012 and the tip cone 90113, and because the jewel bearing 9012 is in single-point contact with the tip cone 90113, the friction force generated when the jewel bearing 9012 and the tip cone 90113 rotate relatively is small, so that the rotation resistance generated by the support to the rotating shaft 904 when the rotating shaft 904 rotates is reduced.
Step 1005: sensing the rotation angle of the rotating shaft through a sensor;
step 1006: and determining the elastic force of the detected blood according to the rotation angle of the rotating shaft.
The specific procedures of step 1005 and step 1006 are as follows: the rotation angle of the rotating shaft is sensed through various sensors, a thrombus elastogram is formed according to the rotation angle of the rotating shaft, and index parameters reflecting the elasticity of the detected blood are obtained according to the thrombus elastogram, or the rotation angle of the rotating shaft is directly converted into the index parameters reflecting the elasticity of the detected blood.
According to the scheme, the embodiments of the invention have at least the following beneficial effects:
1. the first fixed connecting piece in the connecting assembly is fixed to the first supporting assembly of the peripheral through the fixing part, and is attached to one plane of the first supporting assembly of the peripheral through the stabilizing platform, the contact area of the first fixed connecting piece and the first supporting assembly is increased, so that when the first supporting assembly of the peripheral is connected with points of the second fixed connecting piece through the connecting part to rotate around the second supporting assembly, the friction force between the first fixed connecting piece and the first supporting assembly can be increased, the relative movement between the first fixed connecting piece and the first supporting assembly is avoided, and the generation of rotating resistance can be effectively reduced.
2.
