Description

Technical Field

[0001] The present invention relates to the technical field of meat detection, and in particular to a rapid detection method and equipment for meat food. Background Art

[0002] In the field of food safety testing, immunochromatographic detection technology has been increasingly widely used due to its advantages of rapid detection, intuitive signal response, and ease of on-site operation. However, for samples containing complex matrices, the relatively complex pre-treatment steps limit the further application of this technology. Take meat sample testing as an example: as an important part of the residents' dietary structure, meat safety is of vital importance. The application of immunochromatographic detection technology in meat testing cannot be separated from sample pre-treatment.

[0003] Patent No. CN113109554A discloses an integrated device for meat sampling and chromatography detection, which relates to the technical field of meat detection, and comprises: a shell, wherein a accommodating chamber is arranged inside, and a guiding cylinder is rotatably arranged inside the accommodating chamber; a sampling needle, which is movably arranged in the guiding cylinder, and a pop-up mechanism is arranged at one end of the sampling needle, and the pop-up mechanism can pop the sampling needle out of the sampling port, and a sampling needle loading hole is opened on the sampling needle; a chromatography detection structure, which is arranged on the side wall of the shell; a loading needle assembly, comprising an ejection chamber and a loading needle slidably arranged in the ejection chamber, and the loading needle can enter the sampling needle loading hole and push the sample in the sampling needle into the chromatography detection structure; an operating sleeve, which is movably arranged at the other end of the shell, and one end of the operating sleeve is connected to the sampling needle and can drive the guiding cylinder to rotate; the device can realize quick operation of sampling, loading and chromatography detection, and shorten the detection time.

[0017] A rapid detection method for meat food, and use of a rapid detection device for meat food, comprises the following steps:

[0018] S1: Sampling of samples:

[0019] The motor controls the driving gear to rotate. When the driving gear rotates, it will mesh with the control gear ring to rotate. Therefore, the rotation of the gear ring will drive the entire rotating tube to rotate along the axis of the sampling tube. Therefore, the rotating rotating tube can also drive the drill pipe at the bottom to rotate. In this way, the sharp part of the rotating drill pipe can quickly cut the surface of the meat;

[0020] S2: Extraction of small amount of samples:

[0021] Pull the push key rod upward to separate the cone column from the sampling tube, and then continue to pull the cone column. At this time, the first rack will follow the rise of the cone column and move to both sides, so that the first rack will drive the two sampling gears to rotate clockwise. The rotation of the sampling gear rotating clockwise can mesh and drive the second rack and the third rack at the bottom to move relative to each other, which will drive the first mounting frame and the second mounting frame to drive the two detection tubes and the spare tube to move relative to each other and enter the sample retention hole in the sampling tube. When the detection tube and the spare tube are closed, the sample will be cut off, so that samples of four different depths will be saved;

[0022] S3: Preparation of test strips before testing:

[0023] First, place the test paper inside the test box. Since the inside of the test box is inclined, the test paper is also placed obliquely inside the test box.

[0024] S4: Detection:

[0025] During the test, the meat sample can be directly placed on the test paper, and the test paper will perform immunochromatographic detection. The color display on the test paper can be used for rapid detection (the test paper is assembled from a sample pad, a binding pad, a nitrocellulose membrane and absorbent paper). The test paper can quickly and qualitatively detect 8 FQs including MBF, ofloxacin, lomefloxacin, pefloxacin, danofloxacin, enrofloxacin, difloxacin and fleroxacin.

[0026] Compared with the related art, the rapid detection method and device for meat food provided by the present invention have the following beneficial effects:

[0027] Compared with the traditional design, this case is designed with an independent and automatically rotating rotating tube at the bottom of the sampling tube, and the rotating tube can drive the drill tube to rotate. In this way, when the user presses the push button to drive the sampling tube down for sampling, the sharp drill tube can quickly cut the surface of the meat into a cylinder for sampling. Therefore, this design is convenient for users to sample different meat depths for different meat products, ensuring that samples at each depth can be tested, thereby ensuring the accuracy of the test and the comprehensiveness of the data.

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] The invention provides a rapid detection method and equipment for meat food.

[0054] First embodiment:

[0055] Please combine Figures 1 to 8 , a rapid detection device for meat food, comprising an outer tube 1, a detection mechanism 3, a sampling mechanism 4 and a sampling mechanism 6;

[0056] A top cover 8 is installed at the top end of the outer tube 1, and a detection plate 2 is fixedly installed on the side wall of the top cover 8. The detection mechanism 3 includes a detection box 31 fixedly installed on the upper surface of the detection plate 2, and a through slot 32 is provided on the inner side wall of the detection box 31. A test paper 33 is placed on the inner surface of the detection box 31. A through hole 34 is provided inside the detection box 31, and a lifting rod 35 is slidably connected inside the through hole 34. An ejection plate 36 is fixedly installed on the top end of the lifting rod 35. A trachea 37 is sealedly installed on the outer wall of the detection box 31, and a balloon 38 is fixedly installed on the outer end of the trachea 37.

[0057] Combination Figure 3 When testing, the user needs to place the test paper 33 inside the test box 31 first. Since the interior of the test box 31 is inclined, the test paper 33 is also placed obliquely inside the test box 31. When testing, the meat sample can be directly placed on the test paper 33, and the test paper 33 performs immunochromatography testing, and the color display on the test paper 33 can be used for rapid detection.

[0058] Combination Figure 4 When taking out the test paper 33, the user can hold and press the balloon 38 to inflate the through hole 34 through the air tube 37, and the gas ejects the lifting rod 35 to control the ejection plate 36 to rise and push the test paper 33 into the slot 32. After that, the test paper 33 directly slides from the slot 32 to the detection plate 2, so that the test paper 33 can be taken out.

[0059] A pushing key rod 10 is slidably connected to the axis of the top cover 8, a conical column 41 is fixedly arranged inside the outer tube 1 and at the bottom end of the pushing key rod 10, a sampling tube 42 is installed at the bottom of the conical column 41 through a conical clamping rod, a detachable plate 43 is snap-connected to the outer wall of the sampling tube 42, a rotating tube 45 is rotatably connected to the bottom of the sampling tube 42, a drill tube 46 is fixedly arranged at the bottom end of the rotating tube 45, a through sample hole 44 is opened in the middle position of the sampling tube 42, a motor 47 is installed on the inner wall of the sampling tube 42 through bolts, a driving gear 48 is connected to the keyway of the output shaft of the motor 47, a gear ring 49 is fixedly arranged on the inner wall of the drill tube 46, two floating rings 410 are installed at the joint between the rotating part of the sampling tube 42 and the drill tube 46, a connecting tube 411 is fixedly arranged inside the lower part of the sampling tube 42 and at one side of the motor 47.

[0060] Combination Figure 5 , Figure 6 and Figure 7 Before sampling, the user needs to start the motor 47 to control the rotation of the driving gear 48. When the driving gear 48 rotates, it will engage and control the gear ring 49 to rotate. Therefore, the rotation of the gear ring 49 will drive the entire rotating tube 45 to rotate along the axis of the sampling tube 42. Therefore, the rotating rotating tube 45 can also drive the drill pipe 46 at the bottom to rotate, so that the sharp part of the rotating drill pipe 46 can quickly cut the surface of the meat and complete good excavation.

[0061] Combination Figure 5 and Figure 8 The cut circular meat sample will pass through the drill tube 46 and then through the connecting tube 411, and finally enter the sample retention hole 44 for retention.

[0062] The bottom of the notch 32 is in an inclined structure, the top surface of the ejection plate 36 and the bottom surface of the test paper 33 are in contact with each other, and the air pipe 37 and the through hole 34 are in communication with each other.

[0063] The driving gear 48 is meshed with the gear ring 49 , and the upper and lower ends of the connecting tube 411 are connected to the sample hole 44 and the drill tube 46 respectively.

[0064] It can be understood that the rotating tube 45 and the sampling tube 42 are rotatably matched by a "T"-shaped block and a groove, and two upper and lower floating rings 410 are provided at the joint position of the rotating connection. The floating rings 410 can be preferably made of alloy ceramic material, so as to ensure that it has sealing performance and can rotate smoothly.

[0065] The detachable plate 43 and a section of the sampling tube 42 are detachable, so that the user can remove the detachable plate 43 to facilitate the removal of residual samples inside the sample hole 44 and facilitate cleaning.

[0066] This embodiment: Compared with the traditional design, this case is designed with an independent and automatically rotatable rotating tube 45 at the bottom of the sampling tube 42, and the rotating tube 45 can drive the drill tube 46 to rotate, so that when the user presses the push button 10 to drive the sampling tube 42 to descend for sampling, the surface of the meat can be quickly cut into a cylinder for sampling through the rotation of the sharp drill tube 46. Therefore, this design is convenient for users to sample different meat depths for different meat products, ensuring that samples of each depth can be tested, thereby ensuring the accuracy of the test and the comprehensiveness of the data.

[0067] Second embodiment:

[0068] See also Fig. 9 and Fig.12 , and also includes a stabilizing mechanism 5, which includes a positioning frame 51 fixed on both sides of the lower side of the outer tube 1, a stabilizing key rod 52 is slidably connected inside the outer tube 1 and located on both sides of the drill pipe 46, a stabilizing rod 54 is slidably connected to the inner wall of the positioning frame 51, and an inclined plate 53 is fixed inside the positioning frame 51 and located at one end of the stabilizing key rod 52.

[0069] Combination Fig. 9 and Fig.10 : In the first embodiment, when the user presses the push button 10 to control the sampling tube 42 to descend, the outer wall slope of the drill tube 46 will resist the stabilizing button 52 on both sides to move away from each other, so the stabilizing button 52 will drive the inclined plate 53 to move away from the outer tube 1 inside the positioning frame 51. When the inclined surface of the inclined plate 53 contacts the top of the stabilizing rod 54, the stabilizing rod 54 will follow the inclined surface of the inclined plate 53 to move downward and penetrate into the surface of the meat due to the moving away movement.

[0070] The outer walls on both sides above the outer tube 1 are fixed with mounting frames 9, and the sampling mechanism 6 includes mounting plates 61 fixed on both sides of the outer tube 1 and located inside the two mounting frames 9, the interior of the mounting plate 61 is rotatably connected with a sampling gear 62 through a coil spring, the upper and lower parts of the sampling gear 62 are respectively meshed with a first rack 63, a second rack 64 and a third rack 65, a first mounting frame 66 is fixed at the bottom of the second rack 64, two detection tubes 67 are installed inside the first mounting frame 66 by bolts, a second mounting frame 68 is fixed at the bottom of the third rack 65, two spare tubes 69 are installed inside the second mounting frame 68 by bolts, and a locking rod 11 is slidably connected inside the outer tube 1 and below the first mounting frame 66.

[0071] One end of the first rack 63 extends to the outer wall of the cone column 41 , and the first rack 63 , the second rack 64 , and the third rack 65 are slidably connected to the outer tube 1 .

[0072] Combination Fig.11 After the work of the first embodiment is completed, the user needs to pull the push key rod 10 to pull the sampling tube 42 containing the sample into the initial state. At this time, the locking rod 11 has not yet been positioned with the sampling tube 42.

[0073] Combination Fig.12 : The user pushes the locking rod 11 inward to lock it with the sampling tube 42. After the positioning is completed, the user pulls the push key rod 10 upward to separate the cone column 41 from the sampling tube 42, and then continues to pull the cone column 41. At this time, the first rack 63 will follow the rise of the cone column 41 and move to both sides, so that the first rack 63 will drive the two sampling gears 62 to rotate clockwise. The rotation of the clockwise rotating sampling gear 62 can engage and drive the second rack 64 and the third rack 65 at the bottom to move relative to each other, which will drive the first mounting bracket 66 and the second mounting bracket 68 to drive the two detection tubes 67 and the spare tube 69 to move relative to each other and enter the sample hole 44 in the sampling tube 42. When the detection tube 67 and the spare tube 69 are closed, the sample will be cut off, so that four samples of different depths will be saved.

[0074] In this embodiment, when the sampling is in progress, the tapered drill pipe 46 drives the stabilizing key rod 52 to control the stabilizing rod 54 to descend, and quickly penetrates into the surface of the meat. This design ensures that the outer tube 1 can be well stabilized on the surface of the meat during the sampling process, thereby avoiding slipping and preventing the user from getting his hands hurt during the sampling process.

[0075] Secondly, the relatively moving detection tube 67 and spare tube 69 can simultaneously preserve four samples of different depths for the meat in the sample hole 44. The user does not need to test the sample in the spare tube 69, but can keep it as a spare sample, and the sample in the detection tube 67 can be quickly tested on site. Therefore, this design has the function of sample backup and can also prevent the tester from directly contacting the sample.

[0076] Third embodiment:

[0077] See also Fig.13 , and also includes a disinfection mechanism 7, which includes an annular tube 71 installed above the top cover 8, a plurality of nozzles 72 are sealedly installed at the bottom of the annular tube 71, a protrusion bag 73 is sealedly installed on the inner wall of the annular tube 71, a liquid inlet pipe 74 is sealedly installed on the outer wall of the annular tube 71, and a cam 75 is provided on the outer wall of the pushing key rod 10.

[0078] A plurality of nozzles 72 are equidistantly distributed in an annular pattern about the axis of the annular tube 71 , and the liquid inlet pipe 74 is connected to the annular tube 71 via a one-way valve.

[0079] Combination Fig.13: When the user switches from the first embodiment to the second embodiment, the user can choose whether to rotate the push key rod 10 according to the actual situation. If the push key rod 10 is rotated 180 degrees, the raised end of the cam 75 will rotate to the position of the raised bag 73, which will control the compression of the raised bag 73. During compression, the disinfectant inside the ring tube 71 will be sprayed from each nozzle 72 onto the surface of the sampling tube 42.

[0080] It can be understood that the liquid inlet pipe 74 is used to connect with an external disinfectant tank, and the connection of the one-way valve can prevent the disinfectant inside the ring tube 71 from being subjected to pressure backflow.

[0081] In this embodiment: During the sampling and sampling process, the user can choose whether to disinfect the sampling tube 42 according to the actual situation. By adding a disinfection function, the outer surface of the sampling tube 42 that has been sampled once can be treated, and the pathogens can be temporarily and quickly disinfected, thereby further increasing the cleanliness and hygiene of the entire device.

[0082] Please refer to Figures 1 to 13 The working principle of a rapid detection method and device for meat food provided by the present invention is as follows:

[0083] Step S1: Before sampling, it is necessary to start the motor 47 to control the rotation of the driving gear 48. When the driving gear 48 rotates, it will engage and control the gear ring 49 to rotate. Therefore, the rotation of the gear ring 49 will drive the entire rotating tube 45 to rotate along the axis of the sampling tube 42. Therefore, the rotating rotating tube 45 can also drive the drill pipe 46 at the bottom to rotate, so that the sharp part of the rotating drill pipe 46 can quickly cut the surface of the meat and complete good excavation.

[0084] Step S2: When the push key rod 10 is pressed to control the sampling tube 42 to descend, the outer wall slope of the drill tube 46 will resist the stabilizing key rods 52 on both sides to move away from each other, so the stabilizing key rods 52 will drive the inclined plate 53 to move away from the outer tube 1 inside the positioning frame 51. When the inclined surface of the inclined plate 53 contacts the top of the stabilizing rod 54, the stabilizing rod 54 will follow the inclined surface of the inclined plate 53 to move downward and penetrate into the surface of the meat due to the moving away movement.

[0085] Step S3: Push the locking rod 11 inward to lock it with the sampling tube 42. After positioning, the user pulls the push key rod 10 upward to separate the cone column 41 from the sampling tube 42, and then continues to pull the cone column 41. At this time, the first rack 63 will follow the rise of the cone column 41 and move to both sides, so that the first rack 63 will drive the two sampling gears 62 to rotate clockwise. The clockwise rotation of the sampling gear 62 can engage and drive the second rack 64 and the third rack 65 at the bottom to move relative to each other, which will drive the first mounting bracket 66 and the second mounting bracket 68 to drive the two detection tubes 67 and the spare tube 69 to move relative to each other and enter the sample hole 44 in the sampling tube 42. When the detection tube 67 and the spare tube 69 are closed, the sample will be cut off, so that four samples of different depths will be saved.

[0086] Step S4: During the test, the meat sample in the test tube 67 can be directly placed on the test paper 33, and the test paper 33 performs immunochromatographic detection. The test can be quickly detected by the color display on the test paper 33 (the test paper 33 is assembled from a sample pad, a binding pad, a nitrocellulose membrane and a blotting paper). The test paper 33 can quickly and qualitatively detect 8 FQs such as MBF, ofloxacin, lomefloxacin, pefloxacin, danofloxacin, enrofloxacin, difloxacin and fleroxacin.

[0087] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention.

9. A rapid detection method for meat food, used for use with a rapid detection device for meat food as claimed in any one of claims 1 to 8, characterized in that: The following steps are involved: S1: Sampling of samples: The motor controls the driving gear to rotate. When the driving gear rotates, it will mesh with the control gear ring to rotate. Therefore, the rotation of the gear ring will drive the entire rotating tube to rotate along the axis of the sampling tube. Therefore, the rotating rotating tube can also drive the drill pipe at the bottom to rotate. In this way, the sharp part of the rotating drill pipe can quickly cut the surface of the meat; S2: Extraction of small amount of samples: Pull the push key rod upward to separate the cone column from the sampling tube, and then continue to pull the cone column. At this time, the first rack will follow the rise of the cone column and move to both sides, so that the first rack will drive the two sampling gears to rotate clockwise. The rotation of the sampling gear rotating clockwise can engage and drive the second rack and the third rack at the bottom to move relative to each other, which will drive the first mounting frame and the second mounting frame to drive the two detection tubes and the spare tube to move relative to each other and enter the sample retention hole in the sampling tube. When the detection tube and the spare tube are closed, the sample will be cut off, so that four samples of different depths will be saved; S3: Preparation of test strips before testing: First, place the test paper inside the test box. Since the inside of the test box is inclined, the test paper is also placed obliquely inside the test box. S4: Detection: During the test, the meat sample can be directly placed on the test paper, and the test paper will perform immunochromatographic detection. The color display on the test paper can be used for rapid detection (the test paper is assembled from a sample pad, a conjugate pad, a nitrocellulose membrane and absorbent paper). The test paper 33 can quickly and qualitatively detect 8 FQs including MBF, ofloxacin, lomefloxacin, pefloxacin, danofloxacin, enrofloxacin, difloxacin and fleroxacin.
