8 results about "Inverted microscope" patented technology

This invention relates to the field of microscopy and discloses an inverted microscope, including a base with an eyepiece for human observation, an objective lens for magnifying objects rotatably connected to the base, an illumination lamp for increasing brightness, and a transparent stage for placing samples, positioned directly above the objective lens and below the illumination lamp, all fixedly connected to the base via a bracket. The base also includes a cleaning assembly, a dust removal assembly, and a sweeping assembly. This invention effectively avoids the problem of difficulty in removing dust and impurities remaining on the stage, which can affect the stage's light transmittance. Furthermore, the cleaning process on the stage surface also removes dust from the objective lens, improving the device's practicality.

The utility model can flexibly match the tissue of surgical exposure mouse and the mouse of surgical installation observation window are observed using inverted microscope, reduce the development cost of multiple sets of fixed device, can also achieve certain mouse physiological state maintenance function, and compatible various equipment required by experiment, simplify live imaging observation procedure.

This invention discloses an illumination device for solving the concave liquid surface effect in well plate imaging, belonging to the field of microscope light source technology. The device includes an inverted microscope illumination source and several annular light sources distributed in a dome-like pattern around it. The inverted microscope illumination source is composed of a central light source, a collimating lens, and a condenser lens in sequence. The annular light sources contain multiple LED beads, and the size of the rings matches the diameter of the microwells in a common cell culture plate, with adjustable angles. Through the synergistic effect of traditional vertical illumination and dome-shaped oblique illumination, this invention effectively improves the imaging quality of well plates, adapts to microwell plates of different diameters, is easy to operate, and highly practical, providing strong support for cell observation and other related work.

This invention relates to the field of fecal testing, and more specifically, to a method for detecting human parasitic pathogens without the use of slides and coverslips, comprising the following steps: Step 1, adding an appropriate amount of water to the culture wells of a cell culture plate, placing an appropriate amount of feces in the water of the culture well and stirring evenly; Step 2, cutting a piece of textile or nylon mesh of similar size to the culture well and placing it into the culture well to isolate the fecal residue and fecal liquid from each other; Step 3, after stirring and mixing the fecal liquid, transferring the fecal liquid to the culture wells of a new cell culture plate, covering it with the cell plate cover, and examining it under a microscope using an inverted microscope.

The present application relates to the field of parasitic detection method, more particularly, to a kind of etiology parasitic detection method of human body, comprising the following steps;Step 1, add clean water in the culture hole of cell culture plate, take a proper amount of feces and place in clean water and stir evenly;Step 2, the fecal liquid in the culture hole of cell culture plate is transferred to test tube, then the test tube is placed into centrifuge and centrifuged;Step 3, the supernatant in test tube is taken out and placed in another test tube;Step 4, repeat step 2 and step 3 until the fecal liquid is clear;Step 5, take the supernatant of step 4, collect pathogen;Step 6, the supernatant of step 5 is examined by inverted microscope, and the parasitic detection of human body is carried out.
