Filtering equipment

Abstract

The invention provides filtering equipment which is used for separating and purifying exosomes and comprises a filtering device and a vibration device in contact with the filtering device, and the vibration device is used for generating vibration and transmitting the vibration to the filtering device; the vibration device is used for generating periodic cyclic vibration, and in each period, the working time of the vibration device is 0.5-3 seconds, and the stopping time of the vibration device is 0.5-5 seconds. According to the application, the vibration device in contact with the filtering device is arranged, and the vibration device can transmit vibration to the filtering device, so that impurities or effective substances can fall off from a filtering membrane in the filtering device, and the filtering membrane is prevented from being blocked. In addition, the vibration generated by the vibration device is also beneficial to improving the filtering efficiency. In addition, the filtering device can perform primary filtering and secondary filtering on the liquid, so that the filtering concentration is favorably improved. In addition, high filtering efficiency and filtering quality can be obtained by regulating and controlling the working parameters of the vibration device.

Description

technical field [0001] The present application relates to the technical field of material filtration equipment, in particular to a filtration equipment for separating and purifying exosomes. Background technique [0002] Exosomes are small vesicles of biphospholipid membrane structure with a diameter of 30nm-150nm that are continuously secreted by living cells in large quantities. They are considered to be key research objects in the field of in vitro diagnostic research and clinical tumor detection. Early diagnosis of tumors, assessment of tumor metastasis and recurrence, assessment of tumor heterogeneity, dynamic detection of tumor development and efficacy, detection of drug-resistant mutations, and personalized medicine play a huge clinical role. [0003] The existing filtration equipment for separating and purifying exosomes basically consists of a sample pool, a sample guide flow channel, and a filter membrane. However, the existing filtration equipment is prone to the...

Problems solved by technology

However, the existing filtration equipment is prone to the accumulation of effective substances (exosomes) and / or impurities on the filter membrane, which makes the filter membrane clogged, which seriously affects the treatment efficiency and treatment effect.
