Multifunctional self-cleaning pipetting device and application method thereof

Abstract

The invention discloses a multifunctional self-cleaning pipetting device which comprises a liquid inlet pipeline, a liquid storage bin, a pipette, an adapter substitute, a peristaltic pump and a pumppipe. The bottom of the liquid storage bin is connected with the pipette; the top of the liquid storage bin is connected with the bottom of the adapter substitute, a spraying sprinkler is arranged inthe liquid storage bin, and the liquid inlet pipeline penetrates through the adapter substitute and then is connected to the top of the spraying sprinkler; the two ends of the pump pipe are respectively connected with the top of the adapter substitute and the peristaltic pump, and a clamping piece is inserted to the end, close to the liquid storage bin, of the pipette. In addition, the invention also discloses an application method of the multifunctional self-cleaning pipetting device. According to the multifunctional self-cleaning pipetting device, the peristaltic pump can be effectively prevented from being blocked, and liquid including suspension liquid, viscous liquid and clear liquid can be transferred, stored and discharged; automatic cleaning can be realized, the service life can beprolonged, and the cost can be reduced; the one-time treatment capacity is large, 150 ml of liquid can be transferred, and the device is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to an automatic liquid transfer and related cleaning device, in particular to a multifunctional self-cleaning liquid transfer device. In addition, the present invention also relates to a method for using the multifunctional self-cleaning pipetting device. Background technique [0002] The Chinese invention patent application number is CN201811593141.3, which discloses a liquid pipetting device and a liquid pipetting method. The liquid circuit mechanism described in the invention patent is used to suck and fill liquid samples through a disposable pipetting tip. During the descending process of the probe, the air supply to the air pipe by the air supply mechanism can improve the stability of the air pressure in the air pipe, so that when the liquid suction head touches the liquid surface of the body fluid sample , the air pressure in the air pipe changes significantly relative to the air pressure in front of the liquid in contact...

AI Technical Summary

Problems solved by technology

[0005] But, at present in the industries such as medicine, chemical industry, the volume that above three inventions can be transferred each time is little, maximum is no more than 2 milliliters, and can only transfer clarified liquid, and the gun head is disposable, needs to be replaced after adding liquid, cannot self-cleaning regeneration;

[0006] The Chinese invention patent application number is CN201710260855.1, which discloses an automatic cleaning device for pipette tips. The invention can control the automatic cleaning device for pipette tips in the cleaning box to execute the automatic control system of the preset cleaning program. It can effectively solve the cleaning problem of the pipette tip, but this patent is only applicable to the cleaning of the tip of the pipette. transfer problem,

[0007] In order to cooperate with automated use scenarios, realize unattended 24-hour continuous operation, and realize the handling of all types of liquids at the same time, transfer, store, and discharge reaction liquids as needed, and automatically clean online each time without manual opening. The existing products on the market , can not meet the application requirements, the suspension after the completion of the reaction can be transferred, and the single transfer volume is more than 100 ml. Therefore, it is necessary to design and develop a pipetting cleaning device suitable for automated application scenarios
