Embodiment Construction

[0033] Refer to the attached Figure 1 Preferred embodiments of the cell trapping device of the present invention will be described in detail, but the present invention is not limited thereto.

[0034] figure 1 It is a perspective view showing one embodiment of the cell trapping device of this embodiment. figure 2 for figure 1 The II-II line sectional view.

[0035] Such as figure 1 with figure 2 As shown, the cell capture device 100 has a housing 120 and a filter 105. The housing 120 has an inflow port 130 connected to an inflow tube 125 through which the cell dispersion liquid flows in and an outflow tube 135 connected to an outflow tube through which the cell dispersion liquid flows out. The outflow port 140, the filter 105 is arranged in the housing 120, and has a capture region for capturing cancer cells contained in the cell dispersion, at least a part of the capture region serves as an observation for observing the capture region from the outside. The area 145 ,...

Abstract

Provided is a cell trapping device with which a cell trapped on a filter can be observed without having to disassemble the device. The present invention comprises: a housing (120) that includes an inlet (130) to which an inlet pipe (125) is connected for the inflow of a cell dispersion liquid, and an outlet (140) to which an outlet pipe (135) is connected for the outflow of the cell dispersion liquidand a filter (105) that is disposed in the housing (120) and comprising a trapping region to trap a cancer cell in the cell dispersion liquid. The filter (105) is coupled with the housing (120). At least a portion of the trapping region serves as an observation region for the observation of the trapping region from outside. The inlet pipe (125) and the inlet (130) are disposed at a position further outward than the observation region when viewed in a normal direction of the filter (105). The inlet pipe (125) extends in an in-plane direction of the filter (105).

Description

technical field [0001] The present invention relates to a cell trapping device for trapping cancer cells contained in a cell dispersion. Background technique [0002] Cancer is the leading cause of death in all countries in the world. In Japan, more than 300,000 people die of cancer every year. Early detection and treatment are expected. Most of the deaths caused by cancer are caused by the metastasis and recurrence of cancer. Metastasis and recurrence of cancer is caused by cancer cells taking root from the original lesion through blood vessels or lymphatic vessels and infiltrating the blood vessel walls of other organs and tissues to form micro-metastatic lesions. Such cancer cells that circulate in the human body through blood vessels or lymphatic vessels are called circulating tumor cells (circulating tumor cells, hereinafter referred to as “CTCs” as the case may be). [0003] Blood contains a large number of blood cell components such as red blood cells, white blood c...
