Description

Technical Field

[0001] This utility model relates to the field of fish detection technology, specifically a portable, non-destructive device for detecting live fish. Background Technology

[0002] Live fish health monitoring is a crucial aspect of aquaculture, ecological monitoring, and fisheries resource management. Traditional methods mainly include anatomical observation, blood biochemistry analysis, and imaging examinations, but these techniques have significant limitations: invasiveness, equipment dependence, and insufficient real-time capability.

[0003] In recent years, bioelectrical impedance analysis (BIA) technology has been applied to the field of non-destructive testing of live fish due to its advantages such as non-invasiveness and rapid detection. This technology identifies problems such as parasite infection and abnormal physiological state by measuring the differences in the impedance characteristics of different tissues in the fish to weak currents. However, the poor mechanical adaptability of existing bioelectrical impedance analysis devices is a prominent problem. It is difficult to achieve a close fit between the electrode structure of the detection device and the surface of the fish, resulting in uneven current distribution and unstable measurement signals, which in turn affects the accuracy of the detection results. Therefore, a portable non-destructive live fish detection device is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a portable and non-destructive device for detecting live fish, so as to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A portable, non-destructive device for detecting live fish includes a detection box. A bioelectrical impedance analyzer is installed on the left side of the detection box. Constriction airbags are fixedly installed on both the front and rear sides of the inner wall of the detection box. Rubber plates are fixedly installed on opposite sides of the two constriction airbags. Air cushions are fixedly installed on opposite sides of the two rubber plates. A plurality of electrode plates are fixedly installed on opposite sides of the two air cushions. The plurality of electrode plates are electrically connected to the bioelectrical impedance analyzer. An inflation mechanism is provided on the right side of the detection box for inflating the two constriction airbags.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the inflation mechanism includes a U-shaped tube fixedly installed on the right side of the two contraction airbags. The U-shaped tube extends through to the right side of the testing box. A small air pump is fixedly installed on the right side of the testing box, and the output end of the small air pump is fixedly connected to the bottom air inlet of the U-shaped tube.

[0009] Furthermore, four limiting rods are fixedly installed inside the detection box, and the two rubber plates are slidably installed outside the four limiting rods.

[0010] Furthermore, valves are fixedly installed on the top of both of the contraction airbags.

[0011] Furthermore, a storage battery is fixedly installed on the back of the testing box, and the storage battery is electrically connected to the bioelectrical impedance analyzer and the small air pump.

[0012] Furthermore, the front wall of the testing box is fixedly equipped with a number of latches, and the front wall of the top cover of the testing box is fixedly equipped with locking hooks corresponding to the multiple latches.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: When the portable live fish detection device is opened and a live fish is placed inside, the fish will be positioned between two air cushions. The inflation mechanism inflates the contractile air bladder, pushing the rubber plate and air cushions closer together to hold the fish. After holding, multiple electrode plates adhere to the fish's skin. The bioelectrical impedance analyzer applies multi-frequency microcurrents to the fish's surface through the electrode plates. By utilizing the difference in conductivity between healthy and diseased tissues, impedance changes are detected. Combined with database comparison, the health status of the fish can be determined non-destructively and quickly within three seconds, improving detection accuracy. Attached Figure Description

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] Example 1, such as Figures 1-4 As shown, a portable, non-destructive live fish detection device includes a detection box 1. A bioelectrical impedance analyzer 2 is installed on the left side of the detection box 1. Constriction airbags 3 are fixedly installed on both the front and rear sides of the inner wall of the detection box 1. Rubber plates 4 are fixedly installed on opposite sides of the two constriction airbags 3. Air cushions 5 are fixedly installed on opposite sides of the two rubber plates 4. A plurality of electrode plates 6 are fixedly installed on opposite sides of the two air cushions 5. The plurality of electrode plates 6 are electrically connected to the bioelectrical impedance analyzer 2. An inflation mechanism is provided on the right side of the detection box 1. The inflation mechanism is used to inflate the inside of the two constriction airbags 3.

[0022] The testing device can be carried and transferred by holding the handle on the top of the testing box 1. Opening the top cover of the testing box 1 allows the live fish to be placed inside, positioned between the two air cushions 5. At this time, the inflation mechanism operates to inflate the two contractile air bladders 3. The two contractile air bladders 3 expand as they fill with air, pushing the two rubber plates 4 and the air cushions 5 closer together. The two air cushions 5, being made of flexible material, effectively prevent damage to the fish. After the fish is held, multiple electrode plates 6 adhere to the fish's external skin. Subsequently, the bioelectrical impedance analyzer 2 applies multi-frequency microcurrents to the fish's surface through the multiple electrode plates 6. By utilizing the difference in conductivity between healthy and diseased tissues, impedance changes are detected. Combined with intelligent database comparison, the health status of the fish, such as muscle mass, edema, and parasite infection, can be determined non-destructively and quickly within three seconds, significantly improving the accuracy of the test results.

[0023] Example 2, as Figures 2-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0024] The inflation mechanism includes a U-shaped tube 7 fixedly installed on the right side of the two inflatable airbags 3. The U-shaped tube 7 extends through to the right side of the test box 1. A small air pump 8 is fixedly installed on the right side of the test box 1. The output end of the small air pump 8 is fixedly connected to the bottom air inlet of the U-shaped tube 7.

[0025] With this setup, the small air pump 8 generates airflow, which, through the U-shaped tube 7, can inflate the interior of the two contraction airbags 3.

[0026] Example 3, as Figures 2-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0027] The inside of the testing box 1 is fixedly installed with four limiting rods 9, and two rubber plates 4 are slidably installed on the outside of the four limiting rods 9.

[0028] This configuration restricts the two rubber plates 4 to slide inside the detection box 1 by four limiting rods 9, thus preventing the rubber plates 4 and the air cushion 5 from tilting.

[0029] Example 4, as Figures 3-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0030] Valves 10 are fixedly installed on the top of both inflatable airbags 3.

[0031] With this configuration, the valve 10 installed can release the air inside the contraction airbag 3.

[0032] Example 5, as Figures 2-3 As shown, this embodiment is a further improvement based on embodiment 2, and its specific details are as follows:

[0033] A storage battery 11 is fixedly installed on the back of the test box 1. The storage battery 11 is electrically connected to the bioelectrical impedance analyzer 2 and the small air pump 8.

[0034] This configuration allows the installed battery 11 to power the bioelectrical impedance analyzer 2 and the small air pump 8.

[0035] Example 6, as Figure 1 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0036] The front wall of the testing box 1 is fixedly equipped with a number of latches 12, and the front wall of the top cover of the testing box 1 is fixedly equipped with locking hooks 13 corresponding to the multiple latches 12.

[0037] With this configuration, after the top cover of the testing box 1 is closed, multiple latches 12 and multiple hooks 13 are fastened together, which can restrict the connection of the top cover of the testing box 1 to the top of the testing box 1.

[0038] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
