Description

Full-automatic pipettor disinfection device and use method thereof

Technical Field

The invention relates to the technical field of pipette disinfection, in particular to a full-automatic pipette disinfection device and a using method thereof.

Background

The liquid transfer device, also called a liquid transfer gun, is a metering tool for transferring liquid from an original container to another container within a certain range. Is widely used in the fields of biology, chemistry and medical treatment and health care. The frequent use of such tools for pipetting necessitates regular disinfection of the tools, in particular in the biomedical field, the removal of nucleic acid contaminations. If the disinfection is not timely, cross contamination of the front and back experiments can be caused.

The ozone disinfection technology is invented by a German chemist C.F. Scheiben in 1840, and is used in the water treatment disinfection industry in 1856. At present, ozone is widely used in the fields of water treatment, air purification, food processing, medical treatment, medicine, aquaculture and the like, and plays a great role in promoting the development of the industries. Ozone sterilization is a bacteriolytic method, has thorough sterilization, no residue, broad spectrum sterilization, can kill bacterial propagules, spores, viruses, fungi and the like, and can destroy botulinum toxin. In addition, the ozone has a killing effect on the mould. Ozone is a pollution-free disinfectant because ozone is poor in stability and can be decomposed into oxygen or single oxygen atoms quickly, and the single oxygen atoms can be combined into oxygen molecules automatically without any toxic residues. Ozone is gas and can rapidly diffuse into the whole sterilization space, and no dead angle exists in sterilization.

The current methods for disinfecting and removing nucleic acid pollution mainly comprise alcohol soaking and wiping, high-pressure sterilization and ultraviolet irradiation. The alcohol soaking and high-pressure sterilization are only suitable for the lower part of the pipettor, and the alcohol wiping and ultraviolet irradiation are only suitable for the surface disinfection of the pipettor. Pipettor belongs to precision measurement instrument, and non-professional dismantles trouble and influences precision. Therefore, a comprehensive and simple disinfection method is necessary.

s2, adjusting the range of the pipettes to the maximum, then manually and vertically inserting the pipettes into the second placing hole (801) and the first placing hole (701) in sequence (the direction is that a liquid taking button on the pipettes faces upwards), after the pipettes are placed, starting the electric push rod (11) again to move the main screen plate (7) and the auxiliary screen plate (8) downwards to the original positions;

s3, placing the solid plate (9) on the upper side of the pipette, inserting the liquid taking button into the third placing hole (901), inserting the screw (14) into a lock hole on the lifting lug (16), fixing the solid plate (9) and the screw (14) through a nut, placing the extrusion screen plate (10) between the pair of arc plates (13), and rotating the extrusion screen plate (10) to enable the limiting plate (15) to rotate into the limiting groove (1301);

s4, covering the sealing cover (5) and locking and fixing, starting any one disinfection mode (fast mode, normal mode or deep mode) on the control panel (20) to start the disinfection process, taking the normal mode as an example:

the fan (2) is operated, the linear motor (12) is started, the air inlet valve is opened, ozone enters the shell (1) through the air inlet pipe (3), the control panel (20) displays a conventional character, the remaining time, the wind speed and the ozone concentration, when the remaining time is 0, the exhaust valve is opened, the ozone is discharged through the auxiliary screen plate (8), and the fan (2) and the linear motor (12) stop operating;

s5, after the disinfection is finished, the sealing cover (5) is opened, the extrusion screen plate (10) and the solid plate (9) are sequentially taken out, the electric push rod (11) is started to enable the main screen plate (7), the auxiliary screen plate (8) and the pipettor to move upwards, the pipettor is carefully taken out, and the power supply is turned off.
