A device for regulating red blood cells in the blood vessels of living animals

Abstract

The invention provides a device for regulating red blood cells in a blood vessel of a living animal and an application thereof, belonging to the field of optoelectronic technology; the device comprises a laser emission component, an acousto-optic modulation component, a beam broadening component, a short-wave pass dichroic component in sequence along a laser path mirror and inverted objective lens; the device also includes image input and output components, a convex lens, a concentrator and a white light emitting component on the imaging optical path; after the laser emitted from the laser emitting component passes through the acousto-optic modulation component and the beam broadening component in sequence, irradiates the Change the transmission direction of the laser light on the short-wave pass dichroic mirror; after changing the transmission direction, the laser light is focused to the sample chamber through the inverted objective lens. The laser emitted by the laser emitting component will interact with the acousto-optic modulation component to realize the dynamic scanning of the laser focus. Fast scanning can realize the quasi-static distribution of the laser focus in multiple positions, and then be applied to the stable capture and precise arrangement of multiple red blood cells. and rotation control.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a device for regulating red blood cells and its application. Background technique [0002] It is well known that there is a complex vascular network system in animals, which supplies fresh oxygen and nutrients to tissues and organs through continuous blood flow, and takes away metabolic products such as carbon dioxide to maintain normal physiological balance in the body. In-depth understanding of the physiological mechanism of blood flow, non-contact precise intervention and multi-functional control of blood flow will provide potential ideas and alternatives for further clinical diagnosis and treatment, drug delivery and anti-cancer treatment. [0003] At present, technologies based on magnetic fields, ultrasound, and electric fields have been applied to the dynamic regulation of blood flow. However, the above solutions require the invasive implantation of external mater...

Problems solved by technology

However, the above schemes require invasive implantation of external materials, such as implanting magnetically controlled nanoparticles, ultrasound sources, and metal electrodes into blood vessels as manipulation markers or excitation sources. The above materials themselves are poorly compatible with organisms and are prone to induce The immune system feedback in the body reduces the accuracy and stability of the control
