Description

Technical Field

[0001] The utility model relates to the technical field of medical detection equipment, in particular to a portable peripheral blood cell counter. Background Art

[0002] Peripheral blood cells, as an important part of the human body's blood circulation system, mainly include red blood cells, white blood cells (including neutrophils, lymphocytes, monocytes, eosinophils, basophils, etc.) and platelets. These cells play a crucial role in maintaining the normal physiological functions of the body, defending against infections, promoting wound healing and blood coagulation. Therefore, accurately and quickly detecting the quantity, morphology and proportion of various cells in peripheral blood cells is of great significance for the diagnosis, treatment and prognosis evaluation of clinical diseases.

[0003] Traditional methods for peripheral blood cell counting mostly use a hemocytometer (also known as a blood cell counting chamber) under a microscope. A hemocytometer is a precision instrument made of high-quality thick glass, which divides and counts the cells in the sample to be measured through the engraved grid on it. Since its inception, this method has been widely used in the fields of medicine, biology and environmental science due to its simple operation and low cost. A hemocytometer usually includes two identical counting chambers, and each counting chamber is internally divided into a detailed grid system for accurately calculating the number of cells.

[0004] In recent years, with the in-depth development of biomedical research and the rapid development of medical technology, the research and development of portable peripheral blood cell counters has become particularly important to meet the rapid detection needs in scenarios such as primary medical institutions, remote areas, field operations, and emergency rescues.

[0005] Currently, the main body of the hemocytometer used for counting is a glass slide and a coverslip, which are made of glass. When placed, they are prone to collide with each other and may be damaged, affecting peripheral blood cell counting. For this reason, we propose a portable peripheral blood cell counter.
