Cell collection device capable of obtaining multiple samples in hematology department

Abstract

The invention relates to the field of medical apparatus and instruments, in particular to a cell collection device capable of obtaining multiple samples in hematology department. The cell collection device comprises four rectangular perforated groove racks, a rectangular perforated mounting frame, a grip, an inlet control assembly and the like; adjacent rectangular perforated groove racks are fixedly connected; the rectangular perforated mounting frame is fixedly connected to the rectangular perforated groove racks; the grip is fixedly connected to one side of the rectangular perforated mounting frame; and the inlet control assembly is mounted on the rectangular perforated mounting frame in a sliding mode. According to the cell collecting device, through cooperation of the rectangular hole perforated groove racks, a groove opening rectangular frame, a transmission frame, an L-shaped clamping block and devices on the L-shaped clamping block, a closed space is formed in a container when cell tissue fluid is collected; and through cooperation of a Z-shaped compression suction box of a suction assembly, the rectangular perforated groove racks, the groove opening rectangular frame and devices on the groove opening rectangular frame, pressure difference is formed in the rectangular perforated groove racks, and the cell tissue fluid on the samples is fully sucked, so that researchers can quickly collect the cell tissue fluid.

Description

technical field

[0001] The invention relates to the field of medical devices, in particular to a cell collection device capable of obtaining multiple samples in the department of hematology. Background technique

[0002] With the development of modern blood transfusion technology, the use of various components and cells in blood has become an effective means of clinical treatment. Hematopoietic stem cells are adult stem cells in the blood system. They are a heterogeneous group with long-term self-renewal ability and the potential to differentiate into various types of mature blood cells. Red blood cells, platelets, and hematopoietic stem cell components, which are commonly used in clinical treatment, are prone to bacterial contamination due to storage conditions and collection methods. Cells must be cultured without bacteria before clinical use or storage. In the existing collection of cells, researchers need to use collectors to collect and transfer cells when cultivating ...
