Dual-wavelength ultraviolet sterilization incubator

Abstract

The invention discloses a dual-wavelength ultraviolet sterilization incubator which comprises an incubator body, the incubator body is divided into a first sterilization chamber and a second sterilization chamber through a flow guide baffle, an oscillation tray is arranged in the first sterilization chamber, and a third ultraviolet lamp tube is arranged on the lateral upper portion of the oscillation tray. A second ultraviolet lamp tube and a first ultraviolet lamp tube are connected to the left side and the right side of a rear back plate in the second sterilization chamber respectively, an air supply mechanism is arranged in the middle of the rear back plate, the wavelength of ultraviolet rays generated by a third ultraviolet lamp tube is 180-190 nm, the wavelength of ultraviolet rays generated by the first ultraviolet lamp tube and the second ultraviolet lamp tube is 250-260 nm, and the wavelength of ultraviolet rays generated by the second ultraviolet lamp tube is 250-260 nm. The sterilization chamber I is communicated with the sterilization chamber II. According to the incubator, the problem of real-time sterilization of internal circulating air in the sample culture process of the incubator is solved, and normal culture of a sample is not influenced; and a special air path circulating system is combined, so that the problem of no dead angle in sterilization is solved.

Description

technical field [0001] The invention relates to the technical field of biomedical laboratory instruments and equipment, in particular to a dual-wavelength ultraviolet sterilization incubator. Background technique [0002] At present, the sterilization method of the shaking incubator in the existing field adopts an ultraviolet sterilization lamp tube that can generate ozone installed on the top of the inner cavity of the incubator. The sterilization time of the ultraviolet sterilization lamp is set at the end or before the beginning of each incubation of the sample, that is, when there is no culture sample in the incubator. Cells cause damage, so it cannot be run in the process of culturing cells or microorganisms in the incubator; during the culturing operation of the incubator, due to sample addition or sampling, the door of the box is opened from time to time, and the outside air will be exchanged into the inner cavity of the incubator, so the inside of the box The air ...

Problems solved by technology

[0002] At present, the sterilization method of the vibration incubator in the existing field adopts the ultraviolet sterilizing lamp tube that can generate ozone to be installed on the top of the incubator cavity, and the ultraviolet ray and ozone generated by the ultraviolet lamp tube sterilize the environment in the incubator cavity, The sterilization time of the ultraviolet sterilizing lamp tube is set at the end or before the start of each culture of the sample, that is, when there is no culture sample in the incubator. Cells cause damage, so it cannot be operated in the process of cultivating cells or microorganisms in the incubator; during the culturing operation of the incubator, due to sample addition or sampling, the door of the incubator is opened from time to time, and the external air will be exchanged into the inner cavity of the incubator, so the inside of the incubator The air will contain bacteria, which is not conducive to the cultivation of cells or microorganisms, and the current technology cannot solve this problem
