Description

Technical Field

[0001] This utility model belongs to the field of ecotoxicological testing, and specifically relates to a fish embryo separator for ecotoxicological testing. Background Technology

[0002] In ecotoxicological studies of fish embryo culture and exposure, normal embryos often adhere to damaged or necrotic embryos. To prevent damaged or necrotic embryos from affecting the development of normal embryos, they must be separated and removed promptly. Current techniques do not utilize specialized tools for routine procedures; instead, non-specialized, temporary tools are often used, such as disposable plastic straws cut to the appropriate size based on experience. The main drawbacks of this method are: 1. It does not allow for direct and clear visualization of the separation edge; 2. The size of the straw cut based on experience cannot be guaranteed to be appropriate, potentially damaging normal embryos. Utility Model Content

[0005] When using the fish embryo separator for ecotoxicological testing of this utility model, one separator can be held in each hand to separate the embryos from the points where they adhere. The size of the separator ring can be selected according to the number of adhered embryos. Generally, a 4 mm diameter ring is suitable for isolating and separating a single test fish embryo, depending on the size of the embryo. Compared with the prior art, the advantages of this utility model are: the fish embryo separator for ecotoxicological testing allows direct observation of the inside and outside of the separation edge ring, facilitating precise positioning during separation; different sizes of separator rings are designed to suit different embryo sizes or scenarios where multiple embryos are adhered, improving the quality and efficiency of embryo separation operations; in addition, different materials are designed, with the stainless steel fish embryo separator for ecotoxicological testing being washable and reusable, and the plastic fish embryo separator for ecotoxicological testing being a disposable consumable, allowing users to choose according to their needs.

[0006] As a further improvement of this utility model, the separator is a hollow cylinder with a diameter of 3-10 mm, a height of 2.9-3.1 mm, and a wall thickness of 0.1-0.3 mm.

[0007] As a further improvement of this utility model, the diameter of the separator is 3 mm, 4 mm or 10 mm.

[0008] As a further improvement of this utility model, a detachable mechanism is provided between the separator and the handle. The detachable mechanism includes a support base at one end of the handle, a mounting sleeve on the support base, a positioning groove circumferentially formed on the inner wall of the mounting sleeve's hole, a fixing seat at the center of the outer side of the separator, and a mounting head on the outer side of the fixing seat. The mounting head is matched with the mounting sleeve, and a positioning protrusion is circumferentially formed around the mounting head corresponding to the positioning groove. The mounting head is inserted into the mounting sleeve, and the positioning protrusion engages with the positioning groove. The cross-section of the mounting head is rectangular or elliptical. The detachable mechanism facilitates the replacement of separators of different diameters and materials. Simply separate the mounting head of the separator from the mounting sleeve of the handle and replace it with a new separator to complete the replacement.

[0009] As a further improvement of this utility model, the handle has a circular cross-section, and the cross-sectional area of ​​the handle decreases from the end furthest from the separating body to the end closest to the separating body. The cross-sectional area of ​​the end of the handle furthest from the separating body is 3mm². 2 The handle is 14.5-15.5 cm long; the angle between the handle and the outer wall of the separator is 30°.

[0010] As a further improvement of this utility model, the material of the separating body and the handle is stainless steel or plastic.

[0011] To facilitate adjustment of the handle angle, the handle is an adjustable handle relative to the angle of the separated body.

[0012] As a further improvement of this utility model, the separating body is arc-shaped, and the radius of the arc of the separating body is 1.5, 2.0 or 5.0 mm.

[0013] As a further improvement of this utility model, the central angle corresponding to the arc of the separator is 90°-135°, the height of the separator is 2.9-3.1 mm, and the wall thickness of the separator is 0.1-0.3 mm. The four corners of the arc-shaped separator are rounded to prevent sharp corners from damaging the embryo.

[0014] As a further improvement of this utility model, the central angle of the arc formed by the connection point of the handle and the separator and any end of the separator is 20°-30°. Attached Figure Description
