Description

Schistosomiasis detects miracidium hatching viewing device

Technical Field

The utility model relates to a schistosomiasis detects cercaria hatching viewing device.

Background

Schistosomiasis is one of the major infectious diseases in China. Is a zoonosis which seriously harms human health, hinders and influences social and economic development of epidemic areas and has infectivity, endemicity and natural epidemic origin. The diagnosis method of schistosomiasis mainly comprises etiology diagnosis and immunology diagnosis. The immunological diagnosis method mainly detects serum antibodies and antigens, is mainly used as a patient screening and auxiliary diagnosis means, and cannot distinguish current infection, past infection and insect stage identification. The etiological diagnosis is the gold standard for accurate diagnosis of schistosomiasis patients. The etiology diagnosis of schistosomiasis is mainly the stool examination, and the common methods include an egg hatching method and a Kato-Katz method. The latter is to find the worm's egg by direct microscopic examination, but because the distribution of the worm's egg is not uniform in the excrement, the sampling quantity is limited, it is easy to cause missed diagnosis for low or moderate infected human or animal. The egg collecting hatching method has higher detection rate than the Kato-Katz method due to large sampling amount during detection. Therefore, the method is the main method for checking schistosomiasis at present.

When the collected egg hatching method is used for detecting schistosomiasis, the currently common push pipe hatching method and nylon silk collected egg hatching method need to judge the result by observing whether cercaria is hatched or not. The schistosoma miracidium is only in the size of needlepoint (about 99 μm. times.35 μm), and conventionally needs to be observed by naked eyes. In recent years, a miracidium microscope, a dynamic automatic miracidium identification system (device) and the like developed by domestic research institutions improve the detection effect, but all require special equipment, are low in price and are difficult to popularize in basic units. The result is usually observed with the help of an auxiliary magnifier, black paper, a flashlight and the like, and the operation is inconvenient. Meanwhile, the light intensity, the projection angle and the like all influence the result judgment. Therefore, a convenient, economical and applicable technique for assisting hatching method for observing larva is urgently needed.

To sum up, the utility model discloses the problem that will solve is:

(1) the whole background of the larva hatching and observing device is black, so that observation errors caused by observation of factors such as background color change, weather change and insufficient light are avoided.

(2) The larva hatching and observing device can enhance light contrast, and an observer can see larva characteristics clearly.

(3) The miracidium hatching and observing device is convenient to operate and suitable for different operators, the number of lighting systems of the miracidium hatching and observing device can be increased or decreased according to different workloads, and the observing position can be adjusted according to the height and the habit of the observer.
