Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, a thrombus coagulation testing device and testing method of the present invention are composed of two material casings 1, one constant temperature peristaltic pump box 2, one regulating switch 3 and one blood coagulation analyzer 4.

[0023] In this example, if figure 1 As shown, the hose is connected to the material casing 1, the constant temperature peristaltic pump box 2, the regulating switch 3 and the blood coagulation analyzer 4 in sequence. The blood flows out from the outlet of the constant temperature peristaltic pump box, flows through two material sleeves respectively, and flows into the blood coagulation analyzer after fully contacting with the material to be tested, and the tester measures the thrombus content in the blood.

[0024] Such as figure 2 The material sleeve 1 shown is composed of an end cap 11 and...

Abstract

The invention relates to a thrombus coagulation testing device and testing method, and belongs to the technical field of thrombus testing equipment. According to the influence of material surface characteristics on thrombus coagulation, the testing device for testing thrombus coagulation caused by different material surface structures is provided, modular design is adopted, blood is pumped into a pipeline through a constant-temperature peristaltic pump box aiming at the blood compatibility problem of a medical in-vivo material, the blood enters the blood coagulation analyzer after flowing through a material sleeve, and the blood coagulation routine in the blood is tested through the tester. The testing device can be used for performing thrombus coagulation testing on two materials in a double-pipeline mode, so that testers can conveniently compare the advantages and disadvantages of the two materials. The invention provides a more efficient and accurate method for thrombus coagulation test of the surface structure of the in-vivo material.

Description

technical field [0001] The invention relates to a thrombus coagulation testing device and a testing method, belonging to the technical field of thrombus testing equipment. Background technique [0002] Anticoagulant materials are an important part of medical in-body materials, and are used in artificial blood vessels, vascular stents, and blood transfusion catheters. Usually, medical implantable materials will cause thrombus aggregation in the body, and the thrombus aggregation problem will not only affect the service life of the equipment, but also pose a threat to the life of the patient in severe cases. Therefore, how to improve the anticoagulant performance of biomedical materials has always been one of the research tasks and important contents of biomedical materials. [0003] At present, the research on anti-coagulant materials is still in the exploratory stage, and comparing and testing the anti-coagulant properties of different materials can efficiently select the d...
