Description

Automatic film making device

Technical Field

The utility model relates to an automatic film making device.

Background

Microscopic examination is to sample and slice a specimen to be detected, and observe, analyze and judge 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 microscopic method is to smear the sample (such as blood, urine, excrement, sputum, cerebrospinal fluid, serosal cavity hydrops, vaginal secretion, etc.) directly or after adding physiological saline and mixing them, and then smear it, and cover it with glass slide and lightly press it under microscope. The manual wet film microscopic examination has the defects of high requirements on experience and technology of operators, strong subjectivity, biosafety, occupational exposure risk and the like, so that an automatic microscopic examination instrument is used for replacing the manual examination 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 are available for the preparation of special slides for automatic microscopic examination: capillary action and automatic tabletting. 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 conventional automatic tabletting method is to mount a cover glass on a glass slide through a rotating shaft, automatically rotate the cover glass after dripping a sample, and press the cover glass on liquid drops, so that tabletting is finished; however, bubbles are easily generated during the process of rotating the tablet, and therefore, the accuracy of the detection result is affected during microscopic examination.
