Description

Technical Field

[0001] This invention relates to the field of veterinary quarantine sampling technology, and in particular to a microbial sampling device for veterinary quarantine. Background Technology

[0002] In the process of animal husbandry, the prevention and control of livestock and poultry diseases is of paramount importance. Various prevention and control measures are taken to prevent, control, and even eliminate the occurrence and spread of infectious diseases in livestock and poultry. Quarantine work acts as a "firewall," silently protecting the production safety of animal husbandry, the food safety of the people, and public health safety. It is an indispensable public security measure in modern society.

[0003] Animal quarantine sampling mainly includes sampling of animal blood, semen, secretions, excrement, appendages, animal tissues and organs, and animal products. Currently, the main sampling tool for animal secretions is the pharyngeal swab. During sampling, staff hold the pharyngeal swab and insert it into the animal's mouth or nasal cavity. In this process, the staff's hands often have to be inserted into the animal's mouth, which inevitably gets contaminated with oral mucus secretions, making it unhygienic and potentially leading to bacterial infection. Summary of the Invention

[0008] As a further embodiment of the present invention: a connecting bracket is fixedly connected to one side of the control board, the connecting bracket is sleeved on the outside of the blocking part, a rotating sleeve is fixedly connected to the center of the connecting bracket, the rotating sleeve is rotatably installed on the outer wall of the fixed rod, oblique grooves are uniformly provided through the control board, and radially arranged clearance grooves are uniformly provided through the side wall of the clamping disk, and the pin passes through the clearance groove and is slidably installed in the corresponding oblique groove.

[0009] As a further aspect of the present invention: the upper and lower ends of the fixed rod are provided with sliding grooves, and the fixed rod is provided with a sliding cavity along the axial direction inside, and the sliding grooves are connected to the sliding cavity.

[0010] As a further embodiment of the present invention: a push plate is fixedly connected to the end of the push rod, a baffle is fixedly connected to the front end of the push rod, the baffle is slidably installed in the sliding cavity, a support spring is provided between one side of the baffle and the sliding cavity, and sliding sleeves are fixedly connected to the upper and lower ends of the baffle through connecting blocks. The connecting blocks are adapted to be slidably installed in the sliding groove, and the sliding sleeves are slidably sleeved on the outer wall of the fixed rod.

[0011] As a further embodiment of the present invention: the rotating arm is rotatably connected to the sampling cover via a pivot, the front end of the rotating arm is provided with a support portion, the end of the rotating arm is provided with a sliding frame, a transmission rod is provided inside the sliding frame, one end of the transmission rod is provided with a limit slider, the limit slider is adapted to slide on the sliding frame, and the other end of the transmission rod is rotatably connected to the sliding sleeve.

[0012] As a further aspect of the present invention, a flexible pad is provided on the surface of the support portion.

[0013] As a further aspect of the present invention: a positioning ring is fixedly provided at the front end inside the sampling cover, and the pharyngeal swab passes through the positioning ring along the axial direction.

When the pharyngeal swab is inserted into the animal's mouth, the sampling cover can effectively prevent the animal's oral secretions from contacting the hand. After the sampling is completed, the clamping block is released by rotating the control plate inside the sampling cover. At this time, the pharyngeal swab is aligned with the sampling tube and the pharyngeal swab can fall off naturally from the front end. This can effectively avoid the staff from directly contacting the pharyngeal swab after sampling, realize contactless sampling, and effectively improve the cleanliness and safety of the sampling process.

[0015] (2) By setting up a fixed rod, a push rod and a rotating arm, during the sampling process, the staff holds the handle and pushes the fixed rod forward. At this time, the fixed rod will drive the clamping plate and the pharyngeal swab to move forward and squeeze the return spring, thereby adjusting the sampling depth of the pharyngeal swab in the oral cavity. At the same time, the resistance feedback of the return spring can be used to sense the obstruction encountered during the pharyngeal swab insertion in real time, so as to withdraw in time and avoid damage to the animal's oral organs. At the same time, during sampling, the push rod drives the rotating arms at both ends to open. The rotating arms can effectively support and open the animal's oral cavity, making it convenient for the staff to observe the sampling process. At the same time, it can also prevent the animal from suddenly biting its mouth under stress and prevent accidents. Attached Figure Description

[0026] 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.

[0027] Please see Figures 1-7 As shown, the present invention is a microbial sampling device for veterinary quarantine, including a sampling cover 1. A pharyngeal swab 2 is slidably inserted into the center of the front end of the sampling cover 1. A handle 3 is provided in the center of the inside of the sampling cover 1. A fixing rod 4 is fixedly connected to the front end of the handle 3. A clamping plate 5 is fixedly connected to the front end of the fixing rod 4. A sliding rod 102 is fixedly provided on the inner wall of the sampling cover 1 along the axial direction. The clamping plate 5 is slidably installed on the sliding rod 102. A return spring 103 is provided between one side of the clamping plate 5 and the inner wall of the sampling cover 1. A radially sliding clamping block 505 is uniformly arranged circumferentially inside the clamping plate 5. The pharyngeal swab 2 is clamped and fixed by the clamping block 505. A control plate 6 is rotatably installed on one side of the clamping plate 5. The control plate 6 is used to control the opening and closing state of the clamping block 505. A pair of rotating arms 7 are rotatably installed at the upper and lower ends of the sampling cover 1. A push rod 8 is slidably inserted through the handle 3 along the axial direction. The push rod 8 is used to drive the rotating arms 7 to open or close.

[0028] Specifically, by setting up a sampling cover 1 and a clamping plate 5, during the sampling process, the pharyngeal swab 2 is inserted from the front end of the sampling cover 1 and clamped and fixed by the clamping plate 5. The staff holds the handle 3 to control the pharyngeal swab 2 for sampling. The cover-shaped structure of the sampling cover 1 can form a protective effect. When the pharyngeal swab 2 is inserted into the animal's mouth, the sampling cover 1 can effectively prevent the animal's oral secretions from contacting the hand. After the sampling is completed, the clamping block 505 is released by rotating the internal control plate 6 of the sampling cover 1. At this time, the pharyngeal swab 2 is aligned with the sampling tube, and the pharyngeal swab 2 can fall off naturally from the front end. This can effectively avoid the staff directly contacting the pharyngeal swab 2 after sampling, realizing contactless sampling and effectively improving the cleanliness and safety of the sampling process.

[0029] More specifically, by setting up a fixed rod 4, a push rod 8, and a rotating arm 7, during the sampling process, the staff holds the handle 3 and pushes the fixed rod 4 forward. At this time, the fixed rod 4 will drive the clamping plate 5 and the pharyngeal swab 2 to move forward and squeeze the return spring 103, thereby adjusting the sampling depth of the pharyngeal swab 2 in the oral cavity. At the same time, the resistance feedback of the return spring 103 can be used to sense the obstruction encountered by the pharyngeal swab 2 during the insertion process in real time, so as to withdraw in time and avoid damage to the animal's oral organs. During sampling, the push rod 8 drives the rotating arms 7 at both ends to open. The rotating arms 7 can effectively support and open the animal's oral cavity, making it convenient for the staff to observe the sampling process. At the same time, it can also prevent the animal from suddenly biting its mouth under stress and prevent accidents.

[0030] like Figures 2-5 As shown, a blocking part 501 is provided on one side of the clamping disc 5. The throat swab 2 passes through the clamping disc 5 and extends into the blocking part 501. One end of the fixing rod 4 is fixedly connected to the blocking part 501. A rotating groove 502 is provided on the outer wall of the blocking part 501. The control plate 6 is rotatably installed in the rotating groove 502.

[0031] Specifically, by setting the blocking part 501, during the insertion of the pharyngeal swab 2, the pharyngeal swab 2 needs to pass through the clamping plate 5 before it can be clamped and fixed by the clamping block 505. Therefore, the blocking part 501 provides sufficient insertion space for the pharyngeal swab 2. During the insertion process, when the pharyngeal swab 2 is felt to be significantly blocked, it indicates that the pharyngeal swab 2 has been inserted into the blocking part 501, thereby ensuring that the pharyngeal swab 2 passes through the clamping plate 5 and can be effectively clamped and fixed.

[0032] like Figures 4-6 As shown, radial grooves 504 are evenly arranged inside the clamping disk 5, and the clamping block 505 is slidably installed in the corresponding radial groove 504. A pin 506 is fixedly connected to the side wall of the clamping block 505, and a compression spring 507 is provided between the end of the clamping block 505 and the radial groove 504.

[0033] Furthermore, a connecting bracket 601 is fixedly connected to one side of the control plate 6. The connecting bracket 601 is sleeved on the outside of the blocking part 501. A rotating sleeve 602 is fixedly connected to the center of the connecting bracket 601. The rotating sleeve 602 is rotatably installed on the outer wall of the fixed rod 4. Inclined grooves 603 are evenly provided through the control plate 6. Relief grooves 503 are evenly provided through the side wall of the clamping plate 5 along the radial direction. The pin 506 passes through the relief groove 503 and is slidably installed in the corresponding inclined groove 603.

[0034] Specifically, when the control plate 6 is rotated via the rotating sleeve 602, the inclined groove 603 on the control plate 6 will rotate synchronously and apply a pushing force to the corresponding pin 506. At this time, the pin 506 will drive the clamping block 505 to slide inward along the radial slide groove 504, and the compression spring 507 will be compressed and deformed. At this time, the clamping block 505 opens to allow the pharyngeal swab 2 to pass through the middle. After the pharyngeal swab 2 is inserted into place, the rotating sleeve 602 is released. At this time, the clamping block 505 will be quickly pushed out under the elastic force of the compression spring 507 until it abuts against the pharyngeal swab 2, thus achieving rapid clamping of the pharyngeal swab 2. When it is necessary to remove the pharyngeal swab 2, the rotating sleeve 602 is rotated again. The whole process is simple to operate and the transmission is stable. The opening and closing of the clamping block 505 can be achieved by rotating the rotating sleeve 602 inside the sampling cover 1.

[0035] It should be noted that during the sliding process of the clamping block 505 in the radial groove 504, the clearance groove 503 can provide sufficient sliding space for the pin 506 to ensure that the clamping block 505 can slide smoothly in the radial direction.

[0036] like Figures 6-8 As shown, the upper and lower ends of the fixed rod 4 are provided with sliding grooves 401, and the inside of the fixed rod 4 is provided with a sliding cavity 402 along the axial direction. The sliding grooves 401 and the sliding cavity 402 are connected.

[0037] Furthermore, a push plate 801 is fixedly connected to the end of the push rod 8, and a baffle 802 is fixedly connected to the front end of the push rod 8. The baffle 802 is slidably installed in the sliding cavity 402. A support spring 805 is provided between one side of the baffle 802 and the sliding cavity 402. Sliding sleeves 804 are fixedly connected to the upper and lower ends of the baffle 802 through connecting blocks 803. The connecting blocks 803 are adapted to be slidably installed in the sliding groove 401, and the sliding sleeves 804 are slidably sleeved on the outer wall of the fixed rod 4.

[0038] Furthermore, the rotating arm 7 is rotatably engaged with the sampling cover 1 via a pivot. The front end of the rotating arm 7 is provided with a support 701, and the end of the rotating arm 7 is provided with a sliding frame 702. A transmission rod 703 is provided inside the sliding frame 702. One end of the transmission rod 703 is provided with a limit slider 704, which is adapted to slide on the sliding frame 702. The other end of the transmission rod 703 is rotatably engaged with the sliding sleeve 804.

[0039] Specifically, in its natural state, the rotating arm 7 is embedded in the outer wall of the sampling cover 1. When it is necessary to support the animal's mouth during the sampling process, the pusher 8 is pushed forward by the push plate 801. The pusher 8 will drive the baffle 802 to slide forward in the sliding cavity 402. At this time, the support spring 805 begins to compress and deform. At the same time, the baffle 802 will drive the sliding sleeve 804 to move linearly through the connecting block 803. The sliding sleeve 804 will drive the rotating arm 7 to open outward through the transmission rod 703 to achieve the support function for the animal's mouth.

[0040] It should be noted that by utilizing the sliding engagement between the connecting block 803 and the sliding groove 401, not only can the sliding sleeve 804 smoothly slide in a straight line along the fixed rod 4, but rotational constraints can also be applied to the sliding sleeve 804 to prevent it from rotating unnecessarily.

[0041] In addition, by utilizing the sliding cooperation between the limiting slider 704 and the sliding frame 702, the transmission rod 703 can apply a transmission action to the rotating arm 7, while the rotating rod can perform a corresponding relative displacement process when the rotating arm 7 swings, thereby ensuring the stable transmission process of the connecting rod structure.

[0042] In this embodiment, a flexible pad is provided on the surface of the mouth support 701. The flexible pad can be any one of a rubber pad, a sponge pad, or an airbag pad. Its function is to achieve flexible contact with the upper and lower jaws of the animal's mouth, so as to avoid irritation or even injury to the animal.

[0043] like Figure 2 As shown, a positioning ring 101 is fixed at the front end inside the sampling cover 1. The pharyngeal swab 2 passes through the positioning ring 101 along the axial direction. The positioning ring 101 can effectively limit and guide the insertion direction of the pharyngeal swab 2, ensuring that the pharyngeal swab 2 can be accurately inserted along the axial direction.

[0044] The working principle of this invention is as follows: Figures 1-8As shown, during use, the operator holds the handle 3 and rotates the control plate 6 via the rotating sleeve 602. The control plate 6 causes the clamping block 505 to open. At this time, the pharyngeal swab 2 is inserted until the tail end of the pharyngeal swab 2 is blocked by the blocking part 501. Then, the rotating sleeve 602 is released, and the clamping block 505 is quickly pushed out by the elastic force of the compression spring 507 until it abuts against the pharyngeal swab 2, thus achieving rapid clamping of the pharyngeal swab 2. After the pharyngeal swab 2 is stably clamped, the operator holds the handle 3 to control the pharyngeal swab 2 for sampling. The cover structure of the sampling cover 1 can form a protective effect. When the pharyngeal swab 2 is inserted into the animal's mouth, the sampling cover 1 can effectively prevent the animal's oral secretions from contacting the hand. During sampling, the staff member holds the handle 3 and pushes the fixing rod 4 forward. The fixing rod 4 then moves the clamping plate 5 and the pharyngeal swab 2 forward, compressing the return spring 103. This allows adjustment of the sampling depth of the pharyngeal swab 2 within the oral cavity. Simultaneously, the resistance feedback from the return spring 103 allows for real-time sensing of any obstacles encountered during the pharyngeal swab 2's insertion, facilitating timely retraction and preventing damage to the animal's oral organs. During sampling, the push rod 8 opens the rotating arms 7 at both ends, and the support part 701 effectively supports and opens the animal's oral cavity, facilitating observation of the sampling process and preventing sudden clenching of the mouth under stress, thus preventing accidents. After sampling, the push rod 8 is released, the rotating arms 7 retract and close again, and the clamping plate 5 is no longer pushed. The clamping plate 5 and the pharyngeal swab 2 retract from the oral cavity. The pharyngeal swab 2 is then aligned with the sampling tube, and the rotating sleeve 602 is rotated again to release the clamping block 505. At this point, the pharyngeal swab 2 naturally falls from the front end into the sampling tube, completing the entire sampling process.

[0045] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
