Patent number: 11985403Abstract: The embodiments of the present application provides a method and apparatus for preventing heat damage to a thermal imaging camera. The method includes: obtaining a thermal imaging picture of the thermal imaging camera; detecting whether the thermal imaging picture shows that a high-temperature object appears in the picture of the thermal imaging camera; confirming that the thermal imaging picture shows that a high-temperature object appears in the picture, generating a heat damage alarm signal, and closing a baffle if the baffle is not closed currently. In the present application embodiments, after detecting a heat damage alarm signal, that is, after detecting that a high-energy radiating object enters an image picture, the baffle is closed immediately, thereby avoiding the risk of the sensor being permanently burnt due to directly face to the high-energy radiating object.Type: GrantFiled: May 13, 2020Date of Patent: May 14, 2024Assignee: HANGZHOU HIKMICRO SENSING TECHNOLOGY CO., LTD.Inventors: Yang Zhou, Zhenhua Xiao, Yunfei Tang, Liping Wang, Jianjun Xu, Yongyou Pan, Jun Liu, Peng Zhou

Patent number: 11951228Abstract: Provided is a hemostatic composition comprising trypsin and zeolite, wherein pore channels of the zeolite are micropores, the zeolite contains divalent metal cations, and the mass ratio of the trypsin to the zeolite is 1:200-4:10. In the present invention, the trypsin specifically binds to the zeolite, allowing the trypsin to maintain a certain conformation on the surface of the zeolite and to obtain a higher procoagulant activity, thereby obtaining a hemostatic composition with an excellent blood coagulation effect. The hemostatic composition of the present invention has the advantages of a simple preparation method, low cost and convenient use, and can be widely used in hemostasis during trauma and operations, especially in emergent hemostasis in hemophilia patients.Type: GrantFiled: January 28, 2020Date of Patent: April 9, 2024Assignee: Zhejiang UniversityInventors: Jie Fan, Lisha Yu, Liping Xiao, Hao Chen, Xiaoqiang Shang

Patent number: 11154512Abstract: A hemostatic compound is provided. The hemostatic compound comprises molecular sieves and a fiber. The molecular sieves are independently dispersed on a fiber surface of the fiber without agglomeration and directly contact the fiber surface. A first surface of the molecular sieve contacted with the fiber is defined as an inner surface, and a second surface of the molecular sieve uncontacted with the fiber is defined as an outer surface. The molecular sieve forms a growth-matched coupling with the fiber on the inner surface, and the growth-matched coupling refers to that a plurality of molecular sieve microparticles grow to match the fiber surface to form a tightly-coupled coupling interface that matches the fiber surface.Type: GrantFiled: April 7, 2020Date of Patent: October 26, 2021Assignee: Hangzhou Zeo-Innov Life Technology Co., LtdInventors: Jie Fan, Lisha Yu, Liping Xiao, Hao Chen, Xiaoqiang Shang
