The invention provides a particle imaging device. The particle imaging device comprises a fixed lower plate; the fixed upper plate is detachably connected with the fixed lower plate, and an accommodating space is formed between the fixed upper plate and the fixed upper plate; the imaging chamber is arranged in the accommodating space and is provided with a sheath liquid injection port and a waste liquid port; the sample needle is detachably connected with the imaging chamber and can inject a sample into the imaging chamber; the sheath fluid runner is arranged in the imaging chamber and can accelerate and rectify a sample and sheath fluid; and the upper cover plate is matched with the imaging chamber and the sheath fluid flow channel so as to seal the sheath fluid flow channel. The invention further provides a manufacturing method of the particle imaging device.
Description
technical field [0001] The invention relates to the technical field of medical detection equipment, in particular to a particle imaging device and a manufacturing method thereof. Background technique [0002] Among the technologies for observing and analyzing tiny particles, planar flow imaging technology is an advanced analysis technology. It has the advantages of traditional flow counting, and also has a huge advantage that flow counting such as "capable of imaging" does not have. An important part of the application of planar flow imaging technology is the particle imaging chamber. [0003] In the particle imaging chamber, the liquid containing the particles to be analyzed flows together with the buffer, and the fluid channel design of the particle imaging chamber enables the buffer to wrap the flow of the liquid containing the particles to be analyzed, forming an observation zone in the particle imaging chamber Thin fluid strips. The optical imaging system photographs ...
