A digital system for the isolation of circulating tumor cells

Abstract

The invention provides a digital system for circulating tumor cell separation. A central processing unit is respectively connected with a pump loop response timer, an information acquisition unit, a power supply unit and a display unit; a liquid inlet conduit is connected with a purifier through a magnetic separator; the purifier is connected with a filter; a tumor cell collector is arranged on the filter; the filter is connected with a circulation pump through a stirring pump; the pump loop response timer is arranged on the circulation pump; the circulation pump is connected with an output conduit; a pressure sensor is arranged on the output conduit. The digital system for circulating tumor cell separation is simple and convenient in operation, good in separation effect and capable of effectively controlling the diffusion transfer of the tumor cells; when the cells are separated, the irreversible damage to the blood is generated, so that the circulating tumor cell collector is arranged; the healthy blood after the circulating tumor cell separation and the blood platelet separation can be collected and injected back to human body through a blood collecting and injecting device, so that the blood cleaning for a cancerous person is realized, the diffusion transfer of the cancer can be effectively prevented and treated and the therapeutic effect is achieved.

Description

technical field [0001] The invention belongs to the field of biological and medical detection, in particular to a digital system for separating circulating tumor cells. Background technique [0002] Cancer is one of the biggest killers that have seriously endangered human health in recent years, and the death rate it causes ranks among the top in every country in the world. With the development of medical technology, some progress has been made in the diagnosis and treatment of cancer, but most patients will experience recurrence and metastasis to varying degrees. Recent studies have shown that many factors affect the recurrence and metastasis of cancer, among which peripheral circulating tumor cells play a very important role. Circulating tumor cells are tumor cells that are shed from the primary tumor and invade the peripheral blood or lymphatic circulation. [0003] Since Ashworth first discovered tumor cells in the blood of a patient who died of cancer in 1869, researc...

AI Technical Summary

Problems solved by technology

At present, these methods generally have the disadvantages of low capture efficiency, cumbersome operation steps, low sensitivity, and easy irreversible damage to blood samples.

Due to the irreversible damage to the blood sample, the existing separation technology can only conduct preliminary analysis and detection of the blood, but cannot remove the tumor cells in all the blood of cancer patients, so the therapeutic effect cannot be achieved

Existing studies on circulating tumor cells still mainly focus on the separation, detection and analysis of circulating tumor cells. As an effective means of separation and removal, the research on removing all circulating tumor cells in blood has not been reported yet.
