8 results about "Blood coagulation test" patented technology

A coagulation test device for measuring clot time and clot characteristics of whole blood samples under different hemostatic conditions. The test results are used as an aid in the management of patients with unexplained coagulopathy for the purpose of helping the physician to determine appropriate clinical measures to hemostasis in the patient.

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 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.

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.

A sample analyzer (10) and a sample analysis method are provided. The sample analysis device (10) comprises a reaction container supply device (130), a sample distribution device (150), a reagent distribution device (160), a transfer device (140), a controller (200), a first determination device (110) and a second determination device (120), wherein the sample distribution device (150) is used for sucking a sample from a sample container (40) and distributing the sample to the reaction container provided by the reaction container supply device (130); the controller (200) is configured to: control the transfer device (140) to transfer the first reaction vessel (20) provided by the reaction vessel supply device (130) to the first measurement device (110) for measurement of a blood coagulation test item; a transfer device (140) is controlled to transfer the second reaction container (30) provided by the reaction container supply device (130) to a second measurement device (120) for measurement of non-clotting test items; any one reaction vessel provided by the reaction vessel supply device (130) can be selectively used as the first reaction vessel (20) or the second reaction vessel (30). The sample analysis device (10) has a blood coagulation detection function and a non-blood coagulation detection function, and is simple in structure and low in cost.
