Problems solved by technology

Manual operation, on the one hand, is cumbersome to operate, there are manual deviations, and the quality and stability of the detection are greatly reduced. On the other hand, it is not suitable for the current growing detection needs.
At present, there are very few commercial products that use membrane filtration to separate CTCs, and there are problems such as low flux, low stability and low sensitivity.

Embodiment Construction

[0038] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0039] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

The invention discloses a circulating tumor cell capture system. The circulating tumor cell capture system includes a supporting device, a plugging device, a filtering device, a scanning device, a pipetting device and a suction filtering device. The support device has a support seat and a base plate, and the base plate is slidably connected to the support seat; the plug removal device is used to remove the plug on the sample tube; the filter device has a filter; the scanning device It is used to scan and record the information marking code of the sample tube and the information marking code of the filter; the pipetting device is used to suck the sample liquid from the sample tube and send it to the filter; the suction filtering device has a suction head and Suction filter, the suction filter suction head is arranged on the support base for the connection of the filter, the suction filter is communicated with the suction filter suction head for the filter suction head Suction filter described above. The circulating tumor cell capture system has the advantages of simple operation, good stability and high sensitivity.

Description

technical field [0001] The invention relates to the field of detection instruments, in particular to a circulating tumor cell capture system. Background technique [0002] Liquid biopsy is a hot spot in current medical testing. It is a fast and simple method for cancer blood testing, and it is one of the important ways of precision medicine. Circulating tumor cells (CTCs) refer to tumor cells detached from the primary tumor and dissociated in the blood. CTCs are one of the core targets of liquid biopsy because CTCs carry tumor gene information related to patients' individualized medication, and the type and number of CTCs are closely related to prognosis prediction, recurrence risk assessment, and efficacy monitoring. The first prerequisite for the detection of CTCs is the enrichment of CTCs. The current methods for the enrichment of CTCs mainly include immunomagnetic bead adsorption, gradient centrifugation, and membrane filtration. As a simple and efficient method, membr...
