Description

Technical Field

[0001] The embodiments of this utility model belong to the field of laboratory cleaning technology, and more specifically, relate to an exhaust device for a laboratory operating table. Background Technology

[0002] In medical testing, many tests require mixing chemical reagents with samples before further analysis. This mixing process often involves multiple reagents. Many reagents, when mixed, produce large amounts of toxic gases, which can cause irreversible harm to testing personnel. Therefore, it's necessary to remove these harmful gases during mixing to prevent inhalation. Current practice involves installing exhaust systems in laboratories to promptly remove these toxic gases from the enclosed environment, preventing large-scale inhalation. However, this method, with the exhaust vent located at the top of the laboratory, means that workers still inhale significant amounts of the toxic gases during extraction, failing to fundamentally solve the problem.

[0003] Currently, there is a side-exhaust safety test bench on the market, including a test bench body and a side exhaust device. The upper surface of the test bench body is a rectangular test operation surface, and a ring of side exhaust device mounting slots is fixedly installed around the outer edge of the test operation surface. The side exhaust device includes an air pump, an exhaust pipe, and at least one desktop exhaust component. The desktop exhaust component is a rectangular air pumping component, with an open gas inlet on the front facing the test operation surface and a gas outlet on the back opposite the front, connected to the exhaust pipe. A downward-protruding mounting strip is fixedly installed in the center of the bottom surface, and the mounting strip is inserted into the side exhaust device mounting slot. The desktop exhaust component is connected to the air pump through the exhaust pipe. When the air pump is started, it generates negative pressure, which is transmitted to the desktop exhaust component through the exhaust pipe, and the desktop exhaust component exhausts the test operation surface under negative pressure.

[0004] This type of experimental platform is designed to promptly remove gases generated on the platform during use, preventing workers from inhaling toxic gases during the extraction process. However, the side exhaust devices are fixed on both sides of the platform, but operations are not performed in fixed positions. This results in better extraction efficiency for areas closer to the side exhaust devices and poorer extraction efficiency for areas farther away. Furthermore, enlarging the side exhaust devices would obstruct the platform surface and interfere with testing operations. Therefore, a new exhaust system for experimental platforms is needed that can achieve a wider extraction range while avoiding interference with operations on the platform surface.
