Description
Technical Field
The utility model relates to a medical treatment clinical examination equipment especially relates to a wet piece microscope slide.
Background
Microscopic examination is short for microscopic examination, namely, a specimen to be detected is sampled and filmed, and is observed, analyzed and judged under a microscope; human excreta, secretions, exfoliated cells or human tissues, animal tissues, and even plant cells can be used as objects for microscopic examination, and are often used in medicine to assist in the diagnosis of diseases. When a sample (such as blood, body fluid, urine, excrement and the like) or a specimen (such as cells, tissue sections and the like) is observed by a microscope, a slide is used as a carrier, and the slide is generally divided into a slide glass and a cover glass.
The wet film microscopy method is to smear the sample (such as blood, urine, feces, sputum, cerebrospinal fluid, serosal cavity effusion, vaginal secretion and the like) directly or smear the sample after adding physiological saline and mixing the sample evenly, and observe the sample under a microscope after covering a glass slide and slightly pressing the sample.
Manual wet film microscopic examination has high requirements on experience and technology of operators and has the defects of strong subjectivity, biosafety, occupational exposure risk and the like, so that manual work is replaced by an automatic microscopic examination instrument at present. However, since the sheath flow technique (e.g., urine formed component analyzer) is limited by the size of the formed component in the sample, the application range is limited; in the planar laminar flow technology (such as a stool formed component analyzer), since the detection pool is shared, the risk that cross contamination affects the detection accuracy exists. Therefore, the design of the disposable automatic microscopic slide specially aiming at the wet film microscopic method has important significance for improving the detection accuracy and the application universality of the automatic microscopic examination instrument.
At present, two automatic slide preparation methods, namely a capillary action method and an automatic tabletting method, are manufactured for special slides for automatic microscopic examination. The capillary action method is that a cover glass is combined on a glass slide, a ventilated detection chamber is formed between the cover glass and the glass slide, then a sample liquid is dripped to the opening of the detection chamber, the sample liquid is sucked into the detection chamber under the capillary action, and a liquid layer with a certain thickness is formed, so that automatic slide making is completed; however, the liquid layer is too thick, and the detection accuracy is affected by the accumulation of the visible components, so that the space of a common detection chamber is very narrow and easy to block holes. The automatic tabletting method is that a cover glass is arranged on a glass slide through a rotating shaft, and the cover glass is automatically rotated after a sample is dripped to press the cover glass on liquid drops, so that tabletting is completed; but air bubbles are easily generated during the tabletting process, thereby affecting the accuracy of the detection.
Disclosure of Invention
The utility model aims to provide a microscope wet sheet microscopic slide with simple structure and simple operation.
In order to achieve the above purpose, the utility model can adopt the following technical proposal:
wet piece microscope of microscope examines slide, including the slide to and the laminating cover in the cover glass of slide upper surface, the front end rigid coupling of slide has sample mixing portion, and it is close to rear end department and offers and is used for pressing down the mouth of pressing of cover glass is close to press a mouthful front edge department the overflow launder has been seted up along width direction on the slide.
The length of the glass slide positioned on the front side of the pressing opening is larger than that of the pressing opening.
The upper surface of the sample blending part is higher than the upper surface of the glass slide, and a blending blind hole is formed in the sample blending part.
And the left edge, the right edge and the rear edge of the glass slide are provided with anti-overflow enclosing walls.
The anti-overflow peripheral walls positioned on the left side and the right side of the front edge of the pressing opening are symmetrically provided with clamping holes, and the cover glass is provided with wing plates extending into the clamping holes.
The cover glass positioned behind the wing plate is matched with the pressing opening in size.
The glass slide, the sample blending part and the anti-overflow surrounding wall are of an integrally formed structure.
And chamfering the two corners at the front end of the sample uniformly mixing part to form a fool-proof design.
The utility model has the advantages of simple structure and convenient use. The rear end of the cover glass is pressed downwards to penetrate through the pressing opening, and the front end of the cover glass tilts upwards under the action of the lever principle, so that a sample can be easily dripped onto the glass slide; after the dripping of the sample is finished, the rear end of the cover glass is directly loosened, the front end of the cover glass can be automatically pressed on the sample to finish the slide making, the slide making efficiency is greatly improved, and the pollution caused by human intervention is reduced; because the cover glass is the downward pressure to the sample, consequently liquid layer thickness greatly reduced, the preforming in-process can not produce the bubble, and the sample is more even, can not appear tangible gathering, improves the accuracy that detects.
