Description

Technical Field

[0001] The present application relates to the technical field of dissecting tables, and in particular to a dissecting table for animal experiments. Background Art

[0002] Animal experiments are a common research method in the fields of medical experiments, teaching, and scientific research. In various experiments, experiments are often performed through surgery or the results are obtained by dissecting animals after the experiment. In these experimental processes, the use of dissection tables is indispensable.

[0003] The autopsy process is often accompanied by a pungent odor, which comes from the animal body itself and the formalin used to handle the corpse.

[0004] In order to deal with the pungent odor of the dissecting table, the prior art, for example, discloses "A lifting dissecting table" with publication number CN104173165B, which includes a box body, the box body includes a bottom plate and four side plates, and the bottom plate and the four side plates enclose a temporary storage space. Among them, at least one of the four side plates is provided with a plurality of exhaust holes, and the exhaust holes connect the temporary storage space with the exhaust system during the dissecting operation. The lifting dissecting table can directly and effectively absorb the pungent odor during the dissection.

[0005] In addition, "A dissection table for animal experiments" is disclosed in publication number CN209770787U, and its technical solution includes that a ventilation plate and a dissection table are provided on at least one side of the water sink, the ventilation plate is located between the water sink and the dissection table, and has a group of ventilation holes evenly distributed thereon, and is connected to an exhaust fan located below the dissection table through an exhaust duct; this solution uses a downward suction ventilation setting to quickly evacuate the odor generated during the dissection process.

[0006] In the above technical solutions, when dealing with the odor problem caused by the organism during the dissection process, although the suction device can remove some of the odorous gas on the dissection table, the odorous gas on the dissection table is not effectively gathered during the suction, resulting in poor odor treatment effect of these dissection tables. In particular, when dissecting animals infected with pathogenic microorganisms, the negative pressure requirements for the working environment are higher.

[0007] Therefore, how to improve the treatment effect of these pungent odors that appear during the dissection process and improve the prevention effect when performing dissection operations on animals infected with pathogenic microorganisms, improve the working environment, and reduce the physical harm to operators has always been a technical problem that technical personnel in this field need to solve urgently. Summary of the invention

[0008] In order to solve or partially solve the problems existing in the related art, the present application provides a dissection table for animal experiments. By adopting an operating room and an air collecting room with a special structure, when performing dissection experiments on animals, the exhaust fan can fully suck out the odor brought by the organism during the dissection process on the operating table and then discharge it through the exhaust pipe.

[0009] A dissecting table for animal experiments in the present application comprises a shell; the shell is formed by surrounding panels on all sides, the interior is hollow and the top and bottom ends of the shell are open; an operating room and an air collecting chamber are arranged inside the shell; the operating room is composed of a prism-shaped enclosure and a support portion at the bottom end of the enclosure; an air collecting scoop is arranged in the inner cavity of the shell and below the support portion; a chamber directly enclosed by the air collecting scoop, the enclosure, the support portion and the shell is the air collecting chamber; the enclosure and the support portion are both connected to the air collecting scoop through vents; a high-efficiency filter is connected to the bottom end of the air collecting scoop, and the bottom end of the high-efficiency filter is connected to a fan chamber arranged below it through an air duct, an exhaust fan is arranged in the fan chamber, and the fan chamber is connected to an exhaust duct on the outside of the shell through a pipeline.

[0010] Furthermore, the enclosure is formed by four inclined sloping plates, and the support portion is composed of an operating table panel, a filter layer and a support panel which are overlapped in sequence; a plurality of ventilation holes are provided on the inclined plates, the operating table panel and the support panel.

[0011] Furthermore, the support panel is fixedly connected to the bottom end of the support portion by welding via a connecting plate.

[0012] Furthermore, the support panel is fixedly connected to the shell or the inner wall of the wind collecting scoop by welding through a connecting portion.

[0013] Furthermore, the exhaust fan is connected to a fan frequency converter, which is convenient for adjusting the wind force of the exhaust fan according to the size of the odor.

[0014] Furthermore, in order to allow the odor to be better sucked out by the exhaust fan, the operating table panel is in the shape of a hollow rectangular parallelepiped, with ventilation holes opened on the top panel and the bottom panel, and the surrounding panels are closed.

[0019] (1) The dissecting table in the present application, when performing animal dissection in an experimental animal dissection, the animal is placed on a support in the operating room, and the exhaust fan in the fan room is started for exhaust. Under the negative pressure of the exhaust fan, the odor emitted from the operating room is sucked into the air collecting chamber through the vents, and then enters the high-efficiency filter to filter the pathogenic microorganisms that may be contained in the air flow, and finally discharged through the exhaust duct. In particular, the enclosure in the present application is in the shape of a prism, and cooperates with the air collecting hopper, so that the odor brought by the organism during the dissection process can be fully sucked away. Compared with the prior art method of directly opening vents on the panel used for animals and then sucking, the negative pressure exhaust method in the present application is more effective in treating odors.

[0020] (2) The dissection table in the present application is particularly suitable for use in dissection rooms in the protection area of ​​large and medium-sized animal biosafety laboratories, and is also suitable for situations where multiple people need to work together during dissection operations, and can be operated from three sides.

[0021] (3) The cost of the dissection table in this application is obviously advantageous. Compared with similar dissection tables imported from the laboratory, the cost of the dissection table in this application is only about 1 / 5 of that. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] An animal experiment dissecting table in the present application comprises a shell; the shell is surrounded by panels 1 on all sides, the interior is hollow and the top and bottom ends of the shell are open, and an operating room 100 and an air collecting room 200 are arranged inside the shell; in order to facilitate movement, brakeable universal wheels or Foma wheels can be arranged at the four corners of the bottom end of the shell as needed; preferably, the Foma wheel is selected so that a certain lifting distance can be adjusted to meet the installation environment with uneven ground and ensure the levelness of the equipment.

[0028] The operating room 100 is composed of a prism-shaped enclosure 2 and a support part 3 at the bottom of the enclosure 2; a wind collecting scoop 4 is provided in the inner cavity of the shell and below the support part 3; the chamber directly enclosed by the wind collecting scoop 4, the enclosure, the support part 3 and the shell is the wind collecting chamber 200; the enclosure and the support part 3 are both connected to the wind collecting scoop 4 through the vent 6; the bottom end of the wind collecting scoop 4 is connected to a high-efficiency filter 11, and the bottom end of the high-efficiency filter 11 is connected to a fan chamber 8 provided below it through an air guide 7, an exhaust fan is provided in the fan chamber 8, and the fan chamber 8 is connected to an exhaust pipe 9 outside the shell 1 through a pipeline. The high-efficiency filter 11 is used to filter pathogenic microorganisms.

[0029] The function of the operating room 100 is to place the animal body and provide support for performing anatomical experiments on the animal body;

[0030] The function of the air collection chamber 200 is to fully collect the odor brought by the organism during the dissection process in the collection operation room 100 so as to facilitate the exhaust of the odor by the exhaust fan.

[0031] The function of the enclosure 2 designed in a prism shape is to facilitate the gas to enter the air collecting chamber 200 through the air vents 6 opened on the enclosure 2 under the action of negative pressure, thereby reducing its divergence toward the top of the operating room 100.

[0032] Furthermore, the enclosure is formed by four inclined plates 2 designed in an inclined shape, and the support portion 3 is composed of an operation table panel 30, a liquid-absorbing and breathable layer 31 and a support panel 32 which are overlapped in sequence; a plurality of vents 6 are provided on the inclined plates 20, the operation table panel 30 and the support panel 32. In this embodiment, the opening size of the vents 6 is φ6 mm.

[0033] The operation table panel 30 can directly support the animal body to be dissected, and can also play a role in gas-liquid flow through the vents 6 provided thereon; the filter layer 31 can absorb the blood or other liquids produced during the dissection process, and since the filter layer 31 is breathable, it will not affect the absorption of odors. The filter layer 31 can also filter large particles such as monkey hair and dust; the filter layer 31 can be made of non-woven fabrics, nylon mesh, activated carbon filter materials and other materials.

The width of the extension plate 12 is 1-3 cm. More preferably, the wind collecting scoop 4 is conical, and the cone angle of the wind collecting scoop 4 is greater than the cone angle of the enclosure 2. The wind collecting chamber 200 constructed by the design of the extension plate 12, the panel 1, the enclosure 2, and the conical wind collecting scoop 4 is more conducive to the collection of odors.

[0041] Working process of this application:

[0042] During operation, the exhaust fan is started to provide a negative pressure suction environment; then the animal body to be dissected is placed on the operating table panel 30 for dissection, and the blood or other liquids generated during the dissection process can be absorbed by the liquid-absorbing and breathable layer 31; the odor emitted by the animal body during the dissection process enters the high-efficiency filter 11 through the vents 6 on the enclosure and the support part 3 under the suction action of the exhaust fan, and after filtering the pathogenic microorganisms that may be contained in the airflow, it is finally discharged through the exhaust pipe 9; the present application uses an operating room and an air collection room with a special structure to quickly and efficiently evacuate the odor generated during the dissection process.
