Title:
TEST CUP FOR THROMBELASTOGRAM TEST
Document Type and Number:
WIPO Patent Application WO/2021/227437
Kind Code:
A1
Abstract:
A test cup for a thrombelastogram test, consisting of a cup body (1) and a swing rod (2). The swing rod (2) is of a V-shaped structure consisting of a stress rod (22) and a test rod (21). The test rod (21) extends into the cup body (1). The stress rod (22) is located outside the cup body (1). The cup body (1) comprises a supporting structure. An inner groove (23) on a top end of the V-shaped structure of the swing rod (2) is connected to the supporting structure of the cup body (1) by means of line contact, so that the swing rod (2) can swing relative to the cup body (1). The test rod (21) is located in the cup body (1) and immersed into a blood sample, and the stress rod (22) is located outside the cup body (1). During detection, a detection unit component of a detection instrument is connected to the stress rod (22) to drive the swing rod (2) to swing, and the changes in the viscosity and the elasticity of the blood sample are obtained according to the torque change generated when detecting an action of the swing rod (2). A connecting structure between the inner groove (23) on the top end of the V-shaped structure of the swing rod, and the cup body (1) has an extremely small contact area, so that the swing rod (2) can swing approximately without resistance, ensuring that the tests of the viscosity and the elasticity of the blood sample are not affected by interference resistance, and more accurate data can be obtained.
