Cleaning device with convenient-to-replace brush head for gene detector

Abstract

The invention discloses a cleaning device with a convenient-to-replace brush head for a gene detector and belongs to the technical of gene detection. The cleaning device comprises an empty barrel, wherein a liquid outlet pipe is fixedly connected to the middle end of the left side of the empty barrel; a first one-way valve is arranged on the liquid outlet pipe; the liquid outlet pipe is connectedwith a sprayer; a water inlet pipe and a liquid inlet pipe are arranged on the empty barrel; a propelling device is arranged in the empty barrel and comprises a rubber pad, a cylinder and a push rod;the rubber pad surrounds the outer side of the cylinder; the push rod is connected to the rear side wall of the cylinder; a connecting plate is connected to the bottom of the empty barrel; a motor isarranged at the bottom of the connecting plate and connected to a first loop bar; the first loop bar is connected to a second loop bar; a through hole is formed in each of the first loop bar and the second loop bar; a square groove is formed in the second loop bar; a brush head is arranged at the left end of the second loop bar and comprises a connection block and a bristle fixing plate; the connection block and the square groove are in movable connection; a second plug pin is connected to each of the second loop bar and the connection block; and the connection block is connected to the bristle fixing plate. The cleaning device is simple in structure and adjustable in length, and the brush head is convenient to replace.

Description

technical field [0001] The invention relates to the technical field of gene detection, in particular to a cleaning device for a gene detection instrument which facilitates the replacement of brush heads. Background technique [0002] A gene is the basic unit of heredity. A gene or RNA sequence that carries genetic information transmits the genetic information to the next generation through replication, directs the synthesis of proteins to express the genetic information it carries, and thus controls the expression of the traits of individual organisms. Genetic testing is a technology for testing genes through blood, other body fluids, or cells. It takes the peripheral venous blood or other tissue cells of the tested person, amplifies their genetic information, and uses specific equipment to detect the gene molecules in the cells of the tested person. It is a method to detect and analyze the gene types and gene defects contained in it and whether its expression function is no...

Problems solved by technology

[0004] The genetic detector is used to detect the genetic sequence of organisms, so as to diagnose patients with genetic diseases. When testing the test samples, it is necessary to keep the internal environment of the detector clean and hygienic. However, in the process of daily use, There is dust in the ambient air around the genetic detector. After opening the flip cover of the genetic detector, the dust will fall on the detection table inside the genetic detector. After a long time, the detection table and the surrounding side walls inside the genetic detector will There will be some dust attached to it. If the dust falls into the test sample during the test, the accuracy of the test data will be reduced, which will waste the time required for the test and reduce the test efficiency.
