AI Technical Summary
The existing modified Kato thick smear method has problems with uneven smear thickness and size during the tableting process. Feces are easily spilled out during the pressing process, which can lead to missed detections or misjudgments and cause pollution to the laboratory and the environment.
A slide pressing device was designed, comprising a slide base, a spring support rod, and a knob-type pressing plate. The slide is fixed by a slide slot, and the combination of the spring support rod and the knob-type pressing plate achieves uniform control of the pressing of fecal samples and prevents overflow.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of parasitic disease detection, specifically to a smear preparation device for parasite egg specimens using a modified Kato thick smear method. Background Technology
[0002] Parasitic infections not only pose a serious threat to human health but are also a significant public health issue. In the field of parasitic disease diagnosis, the clinical diagnostic standard is the extraction and detection of parasite eggs from the host's body or excrement.
[0003] In detecting parasite eggs in excrement, most existing technologies employ the modified Kato thick smear method. The modified Kato thick smear method is a method that can be both qualitative and quantitative, calculating the number of eggs per gram of feces and estimating the degree of parasitic infection in patients. It is commonly used in epidemiological surveys and for evaluating the effectiveness of prevention and control measures.
[0004] However, in practice, the thickness and size of the smears are often uneven, which can lead to missed detections or misjudgments. At the same time, when technicians are pressing the smears, feces may easily spill out of the hydrophilic transparent cellophane, causing pollution to the laboratory and the environment, and causing physiological discomfort to the technicians. Utility Model Content

[0009] A knob-type pressing plate, connected to the spring support rod, is used to press a fecal sample onto a glass slide. The knob-type pressing plate includes a knob disc and a pressing plate fixing plate. The pressing plate fixing plate is able to adhere to and separate from the glass slide through the spring support rod.
[0010] The beneficial effects of this invention are as follows: This invention is used in the modified Kato thick smear pressing process, which can better control the thickness and size of the pressed smear, prevent fecal leakage during pressing, standardize each smear produced by the device, and provide quality assurance for subsequent microscopic examination.
