[0002] Tissue fixative is a type of reagent commonly used in pathology technology-related departments. Currently, the mainstream tissue fixative is formaldehyde solution. The advantages of formaldehyde fixative are: it can increase tissue toughness and keep the tissue in the state of ex vivo as much as possible (less tissue shrinkage); but its biggest disadvantage is that formaldehyde is carcinogenic, which is a major factor threatening the health of pathology technical workers.
[0003] Under normal circumstances, when pathological staff need to dispense tissue fixative, they can only do so in a fume hood and need to wear a heavy gas mask. To solve this problem, an instrument for safely and quantitatively dispensing tissue fixative is proposed. Utility Model Content

[0008] The metering pump is fixedly installed inside the main box body, the input end of the metering pump is connected to the connecting pipe, and the output end of the metering pump is connected to the liquid outlet tap.
[0009] Through the above technical scheme, when the tissue fixative needs to be packaged, the tissue fixative is first poured into the reagent box, and then the protective cover is opened, the packaging container is placed at the bottom of the liquid outlet tap, the protective cover is closed, and the tissue fixative in the reagent box is sucked in by a metering pump and discharged into the packaging container through the liquid outlet tap. During the packaging process, the air containing formaldehyde is sucked into the activated carbon filter box through a vacuum pump, filtered through the activated carbon filter box and discharged through the exhaust pipe, thereby preventing toxic gases from endangering medical personnel. At the same time, medical personnel do not need to wear disinfection masks when packaging the tissue fixative.
[0010] In a preferred embodiment, a control panel is fixedly mounted on the top of the main box body, and the metering pump and the air extractor are both controlled by the control panel.
[0011] In a preferred embodiment, a sealing soft edge is fixedly mounted on the outer wall of the contact portion between the protective cover and the main box body.
[0012] Through the above technical solution, the sealing between the protective cover and the main box body is improved to prevent the leakage of toxic gases.
[0013] In a preferred embodiment, a sealing door is hingedly connected to the outer wall of the reagent box.
[0014] According to the technical solution, the tissue fixative is replaced by opening the sealed door.
[0015] In a preferred embodiment, a one-way ventilation port is opened on the front outer wall of the main box body.
[0016] Through the above technical solution, when the harmful air in the protective cover is extracted and filtered, the internal air pressure is reduced, and the external fresh air re-enters through the one-way ventilation port.
[0017] In a preferred embodiment, the protective cover is a transparent structure.
[0018] The above technical solution makes it easy to observe the packaging of tissue fixative.
[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are as follows: the utility model provides an instrument for safely and quantitatively dispensing tissue fixative.
[0020] When the tissue fixative needs to be packaged, first pour the tissue fixative into the reagent box, then open the protective cover, place the packaging container at the bottom of the liquid outlet tap, close the protective cover, and use a metering pump to suck the tissue fixative in the reagent box and discharge it into the packaging container through the liquid outlet tap. During the packaging process, the air containing formaldehyde is sucked into the activated carbon filter box through a vacuum pump, filtered through the activated carbon filter box and discharged through the exhaust pipe, thereby preventing toxic gases from endangering medical staff. At the same time, medical staff do not need to wear disinfection masks when packaging tissue fixative. BRIEF DESCRIPTION OF THE DRAWINGS
