Description
Technical Field
[0001] This invention relates to the field of animal disease sample collection technology, specifically to a sample collection device. Background Technology
[0002] When sampling abnormal pigs for existing animal diseases, the first step is to conduct a patrol and observation, tapping the feed trough cover, and registering any pigs that cannot be observed on the abnormal pig form. Abnormal pigs are then marked with crayons upon entering the pen. The second step is to prepare sampling tools according to the number of abnormal pigs, wearing PE gloves, opening the self-sealing bag, placing the sampling tube with the collection cotton inside the self-sealing bag, placing the prepared sampling tube in the treatment box, and wearing a double-ended marker. The abnormal pig form is ready for sampling. Furthermore, during the sampling process, staff need to manually carry a treatment box containing multiple sampling tubes while simultaneously inserting the end of the sampling tube containing the sampling cotton into the mouth of the abnormal pig and pushing it deep into the throat to collect a pharyngeal sample. Afterward, the sampling cotton containing the sample is placed into a self-sealing bag. This process requires not only staff to perform sampling but also to collect the collected samples. When sampling a large number of abnormal pigs, the operation becomes quite cumbersome. When multiple sampling tools and samples need to be processed simultaneously, the staff's operating space is insufficient, which can easily lead to tools being dropped or samples being contaminated. Therefore, we propose a sample collection device. Summary of the Invention

Detailed Implementation
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Example 1 Please see Figures 1 to 4 A sample collection device includes a sampling tube 1, a sampling cotton 2 and a sealing bag 3 disposed at the end of the sampling tube 1, and also includes a fixing belt 4 and a fixing plate 41 disposed on the fixing belt 4. The fixing belt 4 in this application is also provided with Velcro, so as to facilitate fixing the fixing belt 4 to the waist of the staff and play the role of carrying the sampling tube 1. The fixing plate 41 is provided with multiple mounting ports 411, and the mounting ports 411 are provided with receiving covers 5. The bottom of the receiving cover 5 is provided with a receiving cylinder 6, and the receiving cylinder 6 is provided with an opening communicating with the receiving cover 5. The receiving cover 5 and the receiving cylinder 6 in this application are both square in shape, and the mounting ports 411 are also square in shape. A connecting alignment member 7 is provided between the receiving cylinder 6 and the receiving cover 5. Please see Figures 10 to 12 The connecting alignment component 7 includes a connecting plate 71, a connecting rod 72, a connecting spring 73, and a snap-fit plate 74. There are two connecting plates 71, both of which are U-shaped. The two connecting plates 71 are fixedly installed on both sides inside the receiving cylinder 6. One end of the connecting rod 72 is fixedly connected to the connecting plate 71. The connecting spring 73 is sleeved on the outside of the connecting rod 72, and both ends of the connecting spring 73 are fixedly connected to the connecting plate 71 and the snap-fit plate 74, respectively. The snap-fit plate 74 is slidably sleeved on the outside of the connecting rod 72. The receiving cover 5 is provided with a card interface 53 at the position corresponding to the card receiving plate 74.
[0019] The snap-fit plate 74 is provided with a snap-fit end 741 and a pressing end 742 on the side away from the connecting plate 71. The snap-fit end 741 and the pressing end 742 slide through the receiving cylinder 6 respectively, and the snap-fit end 741 snaps into the snap-fit interface 53. Specifically: In this application, a connecting alignment member 7 is provided to facilitate a detachable connection between the receiving cylinder 6 and the receiving cover 5. At the same time, it facilitates the top of the sealing bag 3 to be fitted onto the fixing plug 52 inside the receiving cover 5. When the sampling cotton 2 containing the sample is removed, the receiving cylinder 6 can be disassembled. During disassembly, the two pressing ends 742 on both sides of the receiving cylinder 6 are pressed simultaneously. While pressing the pressing ends 742, the pressing ends 742 push the snap-fit plate 74. The snap-fit plate 74 then moves along the connecting rod 72 toward the inside of the receiving cylinder 6. As the snap-fit plate 74 moves, it can drive the snap-fit end 741 to disengage from the snap-fit interface 53 of the receiving cover 5. At this time, pulling down the receiving cylinder 6 can achieve the disassembly of the receiving cylinder 6.
[0020] The receiving cover 5 is provided with an insertion port 51, and the sampling cotton 2 is inserted into the receiving cylinder 6 through the insertion port 51; The receiving cover 5 has two semi-circular fixing plugs 52 inside, and the two fixing plugs 52 form a circular hole between each other. The diameter of the circular hole is less than or equal to the diameter of the sampling tube 1. The two fixing plugs 52 are used to fix the sampling tube 1. The receiving cover 5 also has a positioning member 8 inside, and the positioning member 8 is used to connect the two fixing plugs 52. Two semi-annular grooves 521 are provided on the outer side of the bottom of the two fixing plugs 52, and the top of the sealing bag 3 is secured to the two semi-annular grooves 521 by a rubber band. The sealing bag 3 is placed on the outside of the sampling cotton 2. Specifically: When installing the sealing bag 3, firstly, the receiving cylinder 6 is not connected to the receiving cover 5. Then, the opening of the sealing bag 3 is placed on the outside of the two fixing plugs 52, and two rubber bands are used to fix the sealing bag 3 to the bottom of the two fixing plugs 52. Then, the receiving cylinder 6 is connected to the receiving cover 5. Please see Figures 5 to 13 The positioning component 8 includes a positioning frame 81, a pushing block 82, a buffer connector 83, a guide rod 84, and a locking component 85. The positioning frame 81 is slidably connected inside the receiving cover 5 and is located outside the two fixed plugs 52. One end of the pushing block 82 is fixedly connected to the positioning frame 81, and a moving opening is provided on one side of the receiving cover 5, through which the pushing block 82 slides. The buffer connector 83 is disposed on both sides inside the receiving cover 5, and the buffer connector 83 is used to connect to the positioning frame 81. The positioning frame 81 has two inclined grooves 811 on both sides, and the inclined grooves 811 on each side form a V shape with each other. The guide rod 84 slides through the inclined groove 811, and one end of the guide rod 84 is fixedly connected to the fixed plug 52. The accommodating cover 5 has a horizontal groove 54 at the position corresponding to the guide rod 84, and the other end of the guide rod 84 is slidably connected to the horizontal groove 54. That is, the guide rod 84 is simultaneously limited by the inclined groove 811 and the horizontal groove 54. The locking element 85 is located inside the receiving cover 5 and on both sides of the positioning frame 81. The top of the positioning frame 81 has two locking holes 812.
[0021] The locking component 85 includes a locking rod 851, a pull plate 852, a locking block 853, and a locking spring 854. There are two locking rods 851, which slide through both sides of the receiving cover 5. One end of the locking rod 851 located on the outside of the receiving cover 5 is fixedly connected to the pull plate 852, and the other end of the locking rod 851 is fixedly connected to the locking block 853. The locking block 853 is slidably connected to the outside of the positioning frame 81. The locking spring 854 is sleeved on the outside of the locking rod 851, and the two ends of the locking spring 854 are fixedly connected to the locking block 853 and the inner wall of the receiving cover 5, respectively. Specific implementation process: In this application, when the sampling tube 1 and the sampling cotton 2 at the end of the sampling tube 1 are placed inside the sealed bag 3, the pushing block 82 is pressed down first. As the pushing block 82 moves down, the positioning frame 81 moves down simultaneously. When the positioning frame 81 moves down, it pushes the guide rod 84 through the four inclined grooves 811. Because the guide rod 84 is limited by the horizontal groove 54, the guide rod 84 drives the fixing plug 52 to deviate from the insertion port 51. When the fixing plug 52 deviates from the insertion port 51, the two fixing plugs 52 expand the rubber band and simultaneously support the opening of the sealed bag 3. Until the locking hole 812 on the positioning frame 81 moves down to the locking block 853, the locking block 853 is locked in place at the locking hole 812 under the reverse elastic force of the locking spring 854, and the positioning frame 81 cannot move. Then, the sampling cotton 2 is put into the sealed bag 3 through the insertion port 51, and no additional force is applied to the support base plate 101. Then, the two pull plates 852 are pulled outward to make the locking block 853 disengage from the locking hole 812. The positioning frame 81 returns to its original position under the action of the buffer connecting frame. At the same time, the two fixing plugs 52 clamp and fix the sampling tube 1. Furthermore, as a further supplementary explanation, in this application, the diameter of the sampling cotton 2 is slightly larger than the diameter of the sampling tube 1, while the diameter of the sampling cotton 2 is smaller than the diameter formed by the two fixing plugs 52, so that the sampling cotton 2 can be stably inserted into the sealed bag 3 through the opening formed by the two fixing plugs 52.
[0022] Meanwhile, when staff take samples from the pharynx of abnormal pigs, they can press the corresponding push block 82 to move the positioning frame 81 down and fix it. After the two fixing plugs 52 move away from each other, the sampling tube 1 is taken out. When the sampling of the pharynx of abnormal pigs is completed, the sampling cotton 2 is put back into the sealed bag 3.
[0023] Please see Figures 13 to 17Both fixed plugs 52 have cutting parts 9 at their bottoms, and the bottom of the container 6 has a support seal 10. The support seal 10 and the two cutting parts 9 cooperate with each other to seal the sampled cotton 2 after sampling.
[0024] The cutting component 9 includes a fixing block 91, a fixing shaft 92, a telescopic rod 93, a torsion spring 94, a spreading rod 95, and a cutting blade 96. There are two fixing blocks 91, both of which are fixedly installed at the bottom of the fixing plug 52. The fixing shaft 92 is fixedly installed between the two fixing blocks 91. One end of the telescopic rod 93 is rotatably sleeved on the outside of the fixing shaft 92, and the other end of the telescopic rod 93 is fixedly connected to the spreading rod 95. The spreading rod 95 is used to spread open the sealed bag 3. The cutting blade 96 is fixedly installed on the side of the support rod 95 away from the sealing bag 3, and the torsion spring 94 is sleeved on the outside of the fixed shaft 92, with the two ends of the torsion spring 94 being fixedly connected to the fixed block 91 and the telescopic rod 93 respectively. In this application, the two support rods 95 support the sealed bag 3 when the fixing plug 52 fixes the sealed bag 3.
[0025] Please see Figures 13 to 14 and Figure 18 The supporting sealing element 10 includes a supporting base plate 101, a lifting element 102, a pressing element 103, and a closing element 104. The supporting base plate 101 is slidably connected inside the receiving cylinder 6 and is located at the bottom of the sealing bag 3. The lifting element 102 is installed at the bottom of the receiving cylinder 6 and is used to connect and support the supporting base plate 101. The pressing element 103 is provided on both sides of the bottom of the receiving cylinder 6, and the pressing element 103 is used to lock the lifting element 102 when it is pressed down; The closing element 104 is installed on the support base plate 101, and the closing element 104 cooperates with the opening rod 95 to seal the sampled cotton 2 after sampling.
[0026] The lifting component 102 includes a lifting spring 1021 and a lifting block 1022. The lifting spring 1021 is fixedly installed at the bottom of the receiving cylinder 6, and the top end of the lifting spring 1021 is fixedly connected to the lifting block 1022. The lifting block 1022 is fixedly installed at the bottom of the support base plate 101.
[0027] The pressing component 103 includes a pressing inclined block 1031, a compression spring 1032, and a guide plate 1033. There are two pressing inclined blocks 1031, which are located on both sides of the lifting block 1022. The lifting block 1022 is provided with a locking hole, and the pressing inclined block 1031 clamps and fixes the lifting block 1022 through the locking hole. There are multiple compression springs 1032. One end of the multiple compression springs 1032 is fixedly connected to the inner wall of the receiving cylinder 6, and the other end of the multiple compression springs 1032 is fixedly connected to the pressing inclined block 1031. The guide plate 1033 is slidably disposed on the top of the pressing inclined block 1031. The guide plate 1033 is fixedly installed inside the receiving cylinder 6, and the bottom of the guide plate 1033 is provided with two guide protrusions 10331. The pressing inclined block 1031 is provided with guide grooves corresponding to the positions of the two guide protrusions 10331.
[0028] The closing element 104 includes a support block 1041, a connecting rod 1042, a closing rod 1043, and a sealing heating plate 1044. There are two support blocks 1041, which are fixedly installed at both ends of the support base plate 101. One end of the connecting rod 1042 is rotatably connected to the support block 1041 through a pin, and the other end of the connecting rod 1042 is rotatably connected to the closing rod 1043. Two limiting grooves 61 are provided on both sides inside the receiving cylinder 6, and both ends of the closing rod 1043 are slidably connected to the limiting grooves 61. The sealing heating plate 1044 is fixedly installed on the side of the closing rod 1043 facing the sampling tube 1. The heat from the sealing heating plate 1044 in this application can slightly melt the sealing bag 3, thereby enabling the sealing bag 3 to perform heat-sealing. When the sealing bag 3 is not in contact with the sealing heating plate 1044, the sealing heating plate 1044 will not affect the sealing bag 3.
[0029] Specific implementation process: When the pharyngeal sample of the abnormal pig is collected, the sampling cotton 2 is placed at the bottom of the sealed bag 3. At the same time, the sampling tube 1 is pressed down, and the sampling cotton 2 presses down on the support base plate 101. When the support base plate 101 is subjected to external pressure, the lifting block 1022 moves vertically downward along the inside of the receiving cylinder 6. When the support base plate 101 moves down, it drives the two support blocks 1041 on it to move down synchronously. Due to the limiting action of the closing rod 1043 and the limiting action of the limiting grooves 61 at both ends of the closing rod 1043, the closing rod 1043 moves towards the opening rod 95 until the two closing rods 1043 push the opening rod 95 towards each other, so that the two opening rods 95 come closer. After the sampling tube 1 is cut off by the cutting blade 96, the sampling tube 1 is cut off. At this point, the clamping opening of the lifting block 1022 moves to the pressing inclined block 1031. Under the reverse elastic force of the compression spring 1032 on it, the pressing inclined block 1031 moves along the clamping opening. At this time, the lifting block 1022 drives the supporting base plate 101 to move continuously downward. The two closing rods 1043 disengage from the spreading rod 95. Then, under the continuous limiting action of the limiting groove 61, the two closing rods 1043 approach each other and are heat-sealed by the sealing heating plate 1044. That is, when the pressing inclined block 1031 is fully inserted into the clamping opening, the lifting block 1022 stops moving, and the bottom of the sampling tube 1 is cut off. At this time, the upper part of the sampling tube 1 can be collected, while the bottom of the sampling tube 1 and the sampling cotton 2 containing the sample are collected and sealed by the sealing bag 3, thus completing the rapid collection of the sample.
[0030] Example 2 Please see Figures 7 to 9 Example 2 is a further supplementary description of Example 1. Specifically, the buffer connector 83 includes a support rod 831, a side plate 832, and a buffer spring 833. There are two side plates 832, which are respectively fixedly installed on both sides inside the receiving cover 5. The support rod 831 is fixedly installed on the side plate 832, and the positioning frame 81 is slidably sleeved on the outside of the support rod 831. The buffer spring 833 is sleeved on the outside of the support rod 831, and the two ends of the buffer spring 833 are respectively fixedly connected to the side plate 832 and the positioning frame 81. Specifically, in this application, there are four support rods 831, which are distributed in pairs on the two side plates 832. By providing multiple support rods 831, the positioning frame 81 can be stably supported. At the same time, in this application, the buffer spring 833, under its own elastic force, makes the positioning frame 81 relatively located on the top of the receiving cover 5. Thus, when the positioning frame 81 is pressed, the pushing block 82 at one end of the positioning frame 81 can be pressed to achieve the pressing effect of the positioning frame 81.
