Embodiment Construction

[0041] The present invention provides a reticulocyte analyzer. In order to make the purpose, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] The invention provides a reticulocyte analyzer, such as Figure 9 As shown, it includes a laser shaping lighting unit 1, a sample processing and delivery unit 3, a subsequent signal processing unit 4, and a sheath flow cell 5, and the laser shaping lighting unit 1 is used for collimating, uniform, and converging shaping of laser light Then irradiate the sample to be tested in the sheath flow cell 5; the sample processing delivery unit 3 communicates with the sheath flow cell 5, and is used to flow the sample to be tested carried by the sheath fluid through the sheath flow A cell; the...

Abstract

The invention discloses a reticulocyte analyzer, comprising a laser shaping lighting unit, a sample processing conveyer unit, a subsequent signal processing unit and a sheath flow pool, wherein the laser shaping lighting unit comprises a light source and a shaping lens structure; laser generated by the light source is shaped by the shaping lens structure; the shaping lens structure comprises at least two shaping lenses which are vertically arranged; at least one cylindrical lens or a double-conical surface lens is arranged inside each of the two shaping lenses; at least one actual or virtual inner focal point exists in the shaping lens structure. At least two vertically arranged shaping lenses are adopted to form the shaping lens structure; the structure modes of the first focal point and the second focal point are thoroughly changed; and the sidelobe phenomenon of a light spot on a short-axis direction is avoided, so that a side-lobe pulse in the subsequent electric signal pulse is thoroughly removed; and the situation of sample misjudgement caused by rusing of sidelobe is also avoided.

Description

technical field [0001] The invention relates to a flow cytometer, in particular to a reticulocyte analyzer. Background technique [0002] Traditional flow cytometry has been widely used in the field of white blood cell differential count and reticulocyte analysis. Such an analyzer is mainly composed of a lighting unit, a sheath flow cell unit, a pressure fluid circuit unit and a signal processing unit. Among them, the lighting unit collimates and shapes the light emitted by the light source (the light source generally adopts laser technology), turns it into a spot with an elliptical cross section, and irradiates it to the sheath flow pool. The sheath flow cell provides an optical detection area. In this area, the sample to be tested is carried in the sheath flow by using the principle of sheath flow, so that the sample cells pass through the area one by one. After the sample cells passing through this area are illuminated by the lighting unit, they emit scattered light in ...
