Intelligent analysis equipment for a blood coagulation test and a blood coagulation inhibition test comprises a main body, the main body is of a cubic structure, a protective cover is arranged at the top of the main body, a groove body is formed in the lower surface of the protective cover, the middle of the groove body is in a protruding shape, the inner wall of a fixing part is attached to the outer wall of a blood coagulation plate, and a flow guide fillet is arranged at the upper end of the side wall of the fixing part. The lower end of the inner wall of the main body and the lower end of the outer wall of the fixing part are enclosed to form the collecting groove, the flow guide fillet and the groove body are used for guiding splashing samples to the groove body, diffusion of the splashing samples to the surrounding environment is reduced, experiment interruption caused by sample pollution is avoided, and therefore smooth proceeding of an experiment and the accuracy of a result are ensured.

The invention provides a blood sampling system and a blood sampling detection method for a blood station, and the method comprises the steps: carrying out the blood coagulation test of a first blood sample, and extracting a backscattering signal after the turbulence phenomenon of the blood; decomposing the backscattering signal into a linear component signal and a nonlinear component signal; extracting the shrinkage rate of fibrin in the first blood sample from all the linear component signals, determining the flow characteristic of the first blood sample through all the nonlinear component signals, and determining the agglomeration index of red blood cells in the uncoagulated blood of the target user by combining the shrinkage rate and the flow characteristic; and correcting the hematocrit in the blood of the target user based on the agglomeration index, and evaluating the blood quality of the target user through the corrected hematocrit. By adopting the scheme provided by the invention, the hematocrit can be subjected to confidence detection under the influence of red blood cell agglomeration.

The present invention belongs to the technical field of medical devices, and discloses a fully automatic liquid transfer device for blood coagulation test, including a driving device, a suction mechanism is connected to the upper front surface of the driving device, a tube-taking mechanism is fixedly connected to the lower surface of the suction mechanism, and a base is fixedly connected to the lower front surface of the driving device. The present invention moves the suction mechanism downward so that the lower end of the pipette is located inside the air inlet pipe, but does not contact the fixed hole or the pipette. When the suction pump is working, air enters the air inlet pipe, the air inlet cavity, and the suction pipe from the gap between the pipette and the fixed hole, and is finally discharged from the exhaust pipe. The inhaled gas will drive the liquid remaining on the outer surface of the bottom end of the pipette to follow the flow or drip, thereby cleaning the liquid remaining on the outer surface of the bottom end of the pipette, thereby solving the problem that the bottom end of the outer surface of the existing pipette will have residual solution, and the residual liquid will enter at the same time during injection, reducing the accuracy of the test.

The invention belongs to the technical field of medical instruments, and discloses a full-automatic blood coagulation test liquid transfer device which comprises a driving device, a suction mechanism is in transmission connection with the upper portion of the front face of the driving device, a barrel taking mechanism is fixedly connected to the lower surface of the suction mechanism, and a base is fixedly connected to the lower portion of the front face of the driving device. The suction mechanism moves downwards, so that the lower end of the pipetting barrel is located in the air inlet pipe and does not make contact with the fixing hole and the pipetting barrel, the suction pump works, air enters the air inlet pipe, the air inlet cavity and the air suction pipe from a gap between the pipetting barrel and the fixing hole, and finally the air is exhausted from the exhaust pipe; the sucked gas can drive residual liquid on the outer surface of the bottom end of the pipetting barrel to flow or drop, so that the residual liquid on the outer surface of the bottom end of the pipetting barrel is cleaned, and the problems that a solution is left at the bottom end of the outer surface of an existing pipetting barrel, the residual liquid enters the bottom end of the outer surface of the existing pipetting barrel at the same time during liquid injection, and the test accuracy is reduced are solved.

A device for performing coagulation tests that measure clotting time and clot characteristics in a whole blood sample under different hemostatic conditions. The test results are used to aid in the management of patients with coagulopathy of unknown etiology, helping the physician determine the appropriate clinical action to stop bleeding.

To provide a blood coagulation test system.SOLUTION: Some embodiments of a blood coagulation test system include an analyzer console device and a disposable cartridge component configured to be removably installed in the console device. In some embodiments, the blood coagulation test system can operate, for example, as an automated thromboelastometry system particularly useful in a point-of-care site.SELECTED DRAWING: Figure 8A

Production was attempted for antibodies that neutralize the activity of a bispecific antibody having F.VIII function-substituting activity, for use in a method for measuring the reactivity of F.VIII in the presence of a bispecific antibody having F.VIII function-substituting activity. As a result, it was discovered that by using the produced antibodies, F.VIII activity in the plasma of a hemophilia A patient can be evaluated accurately by performing APTT-based one-stage clotting assay on a wide range of bispecific antibodies having F.VIII function-substituting activity. It was also discovered that F.VIII inhibitor titer in the plasma of a hemophilia A patient carrying F.VIII inhibitor can be evaluated accurately by APTT-based Bethesda assay.

The invention relates to a test kit used in performing the blood coagulation test known as INR measurement, which enables the user to perform the said test in a practical way at home.
