Abstract

The invention provides a tuning fork resonant type measurement device and method for platelet contractile force. The tuning fork resonant type measurement device comprises a constant temperature sealing bin, a metal shielding case arranged inside the constant temperature sealing bin, a tuning fork sensor mounted in the metal shielding case, an injection hole, communicated with the interior of themetal shielding case, for blood to be detected and a reagent, a tuning fork driving and detection circuit connected with the tuning fork sensor, a temperature control circuit connected with the constant temperature sealing bin, a microcontroller controlling the tuning fork driving and detection circuit and the temperature control circuit for communication, and an intelligent terminal communicatedwith the microcontroller. The device can accomplish the accurate measurement on the platelet contractile force by only using a trace amount of blood.

Description

technical field [0001] The present invention mainly relates to a measurement technology for rapid detection of platelet contraction force in blood, in particular to a measuring device and method for platelet contraction force of a trace blood sample based on a tuning fork resonance sensor. Background technique [0002] Before the patient undergoes surgery, the doctor must understand the patient's hemostatic function in advance. If the hemostatic function is not perfect, the patient may suffer from heavy bleeding during the operation and cause unexpected situations. Therefore, it is a routine inspection that must be performed to know whether the patient's hemostatic function is defective before the operation. Platelets in the blood play a vital role in the hemostatic response. When the integrity of endothelial cells is compromised, intimal matrix proteins are exposed, triggering rapid platelet adhesion to form a hemostatic plug. Therefore, the comprehensive function test of ...
