Description

Technical Field

[0001] The utility model relates to a storage device for animal viscera specimens during class breaks, belonging to the field of storage devices. Background Art

[0002] When teaching anatomy, especially small animal anatomy, the usual dissection subjects are "rabbits" or "mice" and other mammals commonly dissected in laboratories. Since the internal organs, muscle structures, bone structures, and brain structures of mammals are relatively complex, multiple consecutive anatomy courses are often conducted, including the dissection of living animals, the extraction of internal organs, brain, muscle tissue, bones and other body tissues after the dissection, and then the dissection of the internal organs and other body tissues, and the display of the internal organs and other body tissue structures to students.

[0003] When the anatomy class is the last class of the morning course, after the anatomical methods, steps, and theoretical basis are explained, the animal is anesthetized and fixed, and then the dissection is performed. The duration of a single class is often not enough to complete the animal's abdomen and remove the internal organs, and then display the muscle and bone tissue.

[0004] At this time, it is often necessary to wait until the first class of the afternoon course starts before further dissecting the internal organs. The time interval between the last class of the morning course and the first class of the afternoon course in the course schedule is generally 2 hours. If the weather is hot, the lysosomes in the dissected visceral cells will release hydrolases quickly at high temperatures when the first class of the afternoon course starts. The rapidly released hydrolases will cause the visceral cells to decompose themselves, making it impossible to preserve the structure and morphology of the visceral cells well. Excessive temperature may cause protein denaturation, nucleic acid degradation, and changes in enzyme activity. These changes will affect the analysis and detection results of biological molecules in the viscera. The microorganisms on the animal viscera will greatly increase their activity at higher temperatures, quickly use the nutrients in the viscera for metabolic activities, and produce various metabolites, which will cause a large number of metabolites to make the viscera smell, change color, and change texture, resulting in a significant decrease in the display effect of the dissection. Therefore, the removed viscera need to be refrigerated.

[0005] The viscera of small animals are very small, and the anatomy classes are not arranged frequently in the school curriculum. It is a bit wasteful to purchase a refrigerator with a large refrigeration space and a function of continuous refrigeration just to carry the very small dissected viscera and the relatively short refrigeration time. The reasons for applying for funds are not sufficient. Therefore, a simple and small viscera specimen short-term refrigeration device is urgently needed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a storage device for animal visceral specimens during breaks, which can effectively refrigerate and store animal visceral specimens.

[0007] The storage device for animal visceral specimens during breaks of the utility model includes a container upper cover and a main body. The container upper cover covers the top of the main body.

[0008] The main body is in the shape of a rectangular box structure. The main body includes a cover plate and a bottom groove. The cover plate covers the bottom groove. A cold air duct and a metal plate are arranged inside the cover plate. The cold air duct communicates with a wind collecting bin connected to the bottom of the cover plate. The wind collecting bin is connected to the air outlet of an electric air pump through a pipeline. The air inlet of the electric air pump is connected to an air inlet bin arranged inside the bottom groove through a pipeline. The cross-sectional area of the cold air duct is smaller than that of the wind collecting bin.

[0009] For the storage device for animal visceral specimens during breaks, the number of electric air pumps is not less than two, and the electric air pumps are connected in parallel between the wind collecting bin and the air inlet bin through pipelines.

[0010] For the storage device for animal visceral specimens during breaks, there are six cold air ducts, which are arranged in a "one"-shaped array in sequence and evenly. Air outlets corresponding to the cold air ducts are arranged on the side wall of the bottom groove. After the cover plate covers the bottom groove, the cold air ducts are butted and communicated with the air outlets on the bottom groove.

[0011] For the storage device for animal visceral specimens during breaks, a cooling water kettle is arranged inside the bottom groove. An air inlet pipe and an air outlet pipe are inserted on the kettle cover of the cooling water kettle. The air inlet pipe extends to the inner bottom of the cooling water kettle but does not contact the inner bottom surface of the cooling water kettle. The air outlet pipe extends to the inner top of the cooling water kettle. The air inlet pipe and the air outlet pipe are respectively connected to the air outlet end of the electric air pump and the wind collecting bin.

[0012] For the storage device for animal visceral specimens during breaks, the cover plate includes a top plate, a partition plate, a sealing bottom plate and a metal plate. A metal plate installation groove is arranged on the top plate. The metal plate is installed in the metal plate installation groove. Cold air ducts are spaced between adjacent partition plates. The metal plate and the sealing bottom plate respectively block the top and bottom of the cold air ducts.

[0013] For the storage device for animal visceral specimens during breaks, a cooling water kettle observation port is arranged on the bottom groove. The cooling water kettle is located inside the bottom groove at a position corresponding to the cooling water kettle observation port. A cooling water kettle baffle is arranged on the cooling water kettle observation port. High water level indication lines and low water level indication lines are arranged on the cooling water kettle.

[0014] For the storage device for animal visceral specimens during breaks, a power switch is arranged on the outer side wall of the bottom groove. A battery pack is arranged inside the bottom groove. The power supply end of the electric air pump is connected to the battery pack through the power switch.

[0015] The described inter-class storage device for animal visceral specimens has a container upper cover in the shape of a cuboid box with an opening at the bottom. A sealing strip is provided at the opening, and a slot is provided at the top of the cover plate. The slot corresponds to the shape of the bottom opening of the container upper cover, and the opening of the container upper cover is inserted into the slot to connect with the cover plate.

[0016] The described inter-class storage device for animal visceral specimens has an air collecting bin including a bin body and an air collecting bin cover plate, and the air collecting bin cover plate seals the opening of the bin body.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] For the described inter-class storage device for animal visceral specimens, air is pumped into the air collecting bin through an electric air pump. The air in the air collecting bin will enter the cold air duct. Since the cross-sectional area of the cold air duct is smaller than that of the air collecting bin, the flow rate of the air in the air collecting bin will increase after entering the cold air duct. The air with an increased flow rate will enhance its ability to carry away heat. Since the top of the cold air duct is the bottom of the metal plate, according to Bernoulli's equation and the ideal state equation, it can be judged that the air flowing at a higher speed has a lower temperature and can quickly carry away the heat of the metal plate to cool the metal plate. Therefore, placing animal viscera on the metal plate can achieve cooling. With the temperature difference generated between the metal plate and the air above the metal plate, that is, the air enclosed between the container upper cover and the cover plate, the metal plate can cool the air inside the container upper cover. Since heat moves upward, the viscera placed on the metal plate will be quickly cooled. Subsequently, the air inside the container upper cover will be cooled from bottom to top. The container upper cover isolates the air inside it from heat exchange with the outside air, so that the temperature of the air inside the container upper cover and the animal visceral specimens continues to decrease, realizing the refrigeration of animal viscera.

[0019] Lysosomes in the cells of the dissected viscera themselves will delay the release of hydrolytic enzymes due to low temperature. The delayed release of hydrolytic enzymes will cause the animal visceral cells to delay their own decomposition. The inhibition of the self-decomposition of animal visceral cells can preserve the tissue cells in good structure and morphology. At the same time, the microorganisms on the animal viscera will reduce their activity at a lower temperature. After the activity is reduced, they will reduce their metabolism of the nutrients in the viscera, thereby greatly reducing the generation of various metabolites formed after metabolism, avoiding the situation where a large amount of metabolites cause the viscera to stink, change color, and change texture. This enables fresh visceral tissues to be dissected and displayed in the afternoon classes.

[0020] Place a cooling water kettle in the bottom groove so that the air sent by the electric air pump passes through water and carries small water droplets. When accelerating in the cold air duct, the higher-speed airflow will promote the vaporization and heat absorption of the small water droplets in the air, enhancing the ability to absorb and carry away the heat of the metal plate and improving the cooling effect.

[0021] The refrigeration effect of the whole system is different from that of the refrigerator system. It does not require heat exchange agents such as Freon, and only cools down by increasing the air flow rate, without the occurrence of environmental pollution caused by Freon leakage, making it more environmentally friendly and clean.

[0034] As Figures 1 to 9 shown, the animal internal organ specimen interim storage device of the present utility model includes an upper cover 1 of the container and a main body, and the upper cover 1 of the container covers the top of the main body;

[0035] Both the main body and the upper cover 1 of the container are in the shape of a square box. The main body includes a cover plate 5 and a bottom groove 2. The cover plate 5 covers the bottom groove 2. Inside the cover plate 5, there are a cold air duct 27 and a metal plate 22. The cold air duct 27 communicates with the air collecting bin 24 at the bottom of the cover plate 5. The air collecting bin 24 includes a bin body 29 and an air collecting bin cover plate 7. The air collecting bin cover plate 7 covers the opening of the bin body 29 to form a sealed air collecting bin 24 for the bin body 29. There is a sealing strip on the edge of the air collecting bin cover plate 7. After covering the opening of the bin body 29, it can better seal the air collecting bin, so that the air pumped into the air collecting bin 24 by the electric air pump 18 can only enter the cold air duct 27 and will not leak. The air collecting bin 24 is connected to the air outlet of the electric air pump 18 through a pipeline. The air inlet of the electric air pump 18 is connected to the air inlet bin 9 arranged inside the bottom groove 2 through a pipeline. The cross-sections of both the cold air duct 27 and the air collecting bin 24 are rectangular, and the cross-sectional area of the cold air duct 27 is one-twentieth of the cross-sectional area of the air collecting bin 24. On the four side walls of the bottom groove 2, there are respectively an air collecting bin inspection opening 17, a cooling water kettle water replenishing opening, an air outlet 4, and an inspection opening. The side wall with the inspection opening is arranged opposite to the side wall with the cooling water kettle water replenishing opening. The side wall with the air collecting bin inspection opening 17 is arranged opposite to the side wall with the air outlet 4. There is an air collecting bin cover plate 7 on the air collecting bin inspection opening 17. The air collecting bin cover plate 7 is connected by screws to the air collecting bin installation strip 16 to achieve the connection.

[0036] There is a cooling water kettle baffle 3 on the cooling water kettle water replenishing opening. The cooling water kettle baffle 3 is connected by screws to the cooling water kettle baffle installation strip 13 to achieve the connection. There is an inspection opening cover plate 8 on the inspection opening. The inspection opening cover plate 8 is installed by screws on the inspection opening installation strip 19 to achieve the connection. Inside the bottom groove 2, there is an air inlet bin 9. The opening of the air inlet bin 9 faces the inspection opening. After the inspection opening cover plate 8 covers the inspection opening, an air inlet channel 10 is formed on the side wall of the bottom groove 2 corresponding to the inspection opening. Air passes through the air inlet channel 10 and enters the bottom groove 2, and then enters the air inlet bin 9. There is an air inlet bin air outlet 11 on the air inlet bin 9. The air inlet bin air outlet is connected to the air inlet end of the electric air pump 18 through a pipeline.

[0037] For the animal internal organ specimen interim storage device described above, the number of electric air pumps 18 is two. The air outlets of the two electric air pumps 18 are connected to the air inlet pipe of the cooling water kettle 12 through a pipeline. The air outlet pipe of the cooling water kettle 12 is connected to the air collecting bin air inlet 25 of the air collecting bin 24. The air inlets of the electric air pumps 18 are connected to the air inlet bin air outlets 11 of the air inlet bin 9 arranged inside the bottom groove 2 through a pipeline. That is, in order to ensure that the air flow rate in the air collecting bin can be higher in this application, so that the air can flow more rapidly into the cold air duct 27, thereby ensuring the ability to reduce the temperature.

[0038] The described animal internal organ specimen interim storage device, the cover plate 5 includes a top plate 23, a partition plate 21, a bottom sealing plate 26 and a metal plate 22. A metal plate installation groove 20 is provided on the top plate 23, and the metal plate 22 is installed in the metal plate installation groove 20. An air cooling duct 27 is spaced between adjacent partition plates 21. The metal plate 22 and the bottom sealing plate 26 respectively seal the top and bottom of the air cooling duct 27. There are six air cooling ducts 27, which are arranged in a "one" - shaped array and evenly spaced in sequence. An air outlet corresponding to the air cooling duct 27 is provided on the side wall of the bottom groove 2. After the cover plate 5 covers the bottom groove 2, the air cooling duct 27 is docked and communicated with the air outlet. The two side walls of the air cooling duct 27 are composed of the side walls of two adjacent partition plates 21. The top wall of the air cooling duct 27 is the bottom wall of the metal plate 22, and the bottom wall of the air cooling duct 27 is the top wall of the bottom sealing plate 26. The bottom sealing plate 26, the top plate 23, the partition plate 21 and the metal plate 22 are bonded with a dense glue to ensure the seam sealing and guarantee the airtightness of the air cooling duct 27. After installation, one end of the air cooling duct 27 is communicated with the air collecting bin 24, and the other end is communicated with the air outlet 4 on the side wall. The air in the air collecting bin 24 is accelerated in the air cooling duct 27 and then discharged from the air outlet 4.

[0039] The described animal internal organ specimen interim storage device, a cooling water kettle 12 is provided in the bottom groove 2. The cooling water kettle 12 is provided with an air inlet pipe and an air outlet pipe. The air inlet pipe extends to the inner bottom of the cooling water kettle 12, and the air outlet pipe extends to the inner top of the cooling water kettle 12. The air inlet pipe and the air outlet pipe are respectively communicated with the air outlet end of the electric air pump 18 and the air collecting bin 24. So that the air sent by the electric air pump 18 passes through water in the cooling water kettle 12, thus making the air carry small water droplets. When the air with small water droplets accelerates in the air cooling duct 27, it will promote the vaporization and heat absorption of the small water droplets in the air, enhance the ability to absorb and carry away the heat of the metal plate 22, and improve the cooling effect.

[0040] The described animal internal organ specimen interim storage device, a cooling water kettle observation port is provided on the bottom groove 2. The cooling water kettle 12 is located in the bottom groove 2 at the position corresponding to the cooling water kettle observation port. A cooling water kettle baffle 3 is provided on the cooling water kettle observation port. High water level indication lines and low water level indication lines are provided on the cooling water kettle 12. The cooling water kettle 12 can use water or alcohol according to the usage scenario. When adding water, it cannot be lower than the low water level indication line, otherwise the air cannot pass through water and cannot carry small water droplets. When adding water, it cannot exceed the high water level indication line, otherwise a large amount of water will enter the air outlet, resulting in a large amount of water entering the air collecting bin 24, making the whole device seep water and also affecting the air flow. A plug - in board 14 is connected to the bottom of the cooling water kettle 12. The cooling water kettle is pushed into or pulled out of the bottom groove by pushing and pulling the plug - in board 14, which is convenient for replenishing water to the cooling water kettle. A cooling water kettle limiting plate 28 is provided in the bottom groove 2 to prevent the cooling water kettle 12 from being too close to the inside and difficult to take out, thereby limiting the depth of the cooling water kettle 12 extending into the bottom groove 2.

[0041] For the animal viscera specimen interim storage device described above, a power switch is provided on the outer side wall of the bottom groove 2, a battery pack 15 is provided inside the bottom groove 2, and the power supply end of the electric air pump 18 is connected to the battery pack 15 through the power switch.

[0042] For the animal viscera specimen interim storage device described above, the container upper cover 1 has a cuboid box-like structure with an opening at the bottom, a sealing strip is provided on the opening, a slot 6 is provided on the top of the cover plate 5, the slot 6 corresponds to the shape of the opening at the bottom of the container upper cover 1, and the opening of the container upper cover 1 is inserted into the slot 6 to realize the connection with the cover plate 5.

[0043] Working principle:

[0044] When starting to work, close the power switch, the two electric air pumps 18 are connected to the battery pack 15, start to work, and air enters the air collecting chamber 24 from the outside through the air inlet chamber 9, the air outlet of the air inlet chamber 11, the electric air pump 18, and the air inlet of the air collecting chamber 25.

[0045] The gas in the air collecting chamber 24 enters the cold air duct 27, and the sum of the cross-sectional areas of the six cold air ducts 27 is one-twentieth of the sum of the cross-sectional areas of the air collecting chamber 24.

[0046] According to Bernoulli's equation:

[0047] gh = constant

[0048] The constant in the air collecting chamber 24 and the cold air duct 27 is the same, and the height difference between the air collecting chamber 24 and the cold air duct 27 is extremely small and can be ignored, so gh can be ignored, therefore:

[0049]

[0050] Where P is the static pressure of the air, ρ is the density of the air, is the air flow velocity in the air collecting chamber 24, is the air flow velocity in the cold air duct 27, g is the acceleration due to gravity, and h is the height of the object.

[0051] According to the fluid continuity equation, it can be known that:

[0052] =

[0053] is the cross-sectional area of the air collecting chamber 24, is the cross-sectional area of the cold air duct 27, and the cross-sectional area of the air collecting chamber 24 is 20 times that of the cold air duct 27, so it can be known that > .

[0054] Substituting into Bernoulli's equation, it can be known that = , so the air static pressure in the air collecting bin 24 is much greater than the air static pressure in the cold air duct 27.

[0055] According to the ideal gas state equation:

[0056] PV = nRT

[0057] P is the air static pressure, V is the gas volume, n is the number of moles of the gas, R is the ideal gas constant, and T is the temperature of the gas.

[0058] The volume of the gas flowing through, the volume of the gas flowing from the air collecting bin 24 into the cold air duct 27 is the same, the number of moles of the gas is also the same, and the ideal gas constant is also the same. In this way, the temperature of the gas is directly proportional to the pressure of the gas. Since the gas static pressure in the cold air duct 27 is much lower than the gas static pressure in the air collecting bin, the temperature of the gas in the cold air duct 27 will be much lower than that in the air collecting bin 24, thus achieving a refrigeration effect.
