DETAILED DESCRIPTION

[0017] The specific implementation methods of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0018] Embodiment 1: like Figure 1-Figure 5As shown, a highly protective veterinary sampling swab comprises a swab head 10, an outer tube 20, an inner tube 30, a plug rod 40, a hoop 50 and a bag 60, wherein the swab head 10 comprises a flocked end 11, an extension rod 12, a limiting plate 13 and a clamping end 14 which are fixedly connected in sequence, the flocked end 11 is in the shape of a water drop, which is convenient for adhering to the sample to be tested, and the clamping end 14 is used to clamp the swab head 10 on one end of the outer tube 20. Specifically, the clamping end 14 comprises a cylindrical portion 141 and a conical portion 142, the cylindrical portion 141 is fixedly connected between the limiting plate 13 and the conical portion 142, and the end of the conical portion 142 close to the cylindrical portion 141 is its bottom end. Since the outer diameter of the bottom end of the conical portion 142 is greater than the outer diameter of the cylindrical portion 141, a first clamping groove 143 is formed between the limiting plate 13 and the conical portion 142, and the outer tube A first clamping ring 21 that is clamped and matched with the first clamping groove 143 is fixed inside the end of 20 close to the swab head 10, and a plurality of radial grooves 145 are provided on the clamping end 14. The plurality of radial grooves 145 separate the clamping end 14 as a whole into a plurality of unconnected parts, so that each part of the clamping end 14 can be elastically deformed inwardly. During production and assembly, it is only necessary to axially insert the clamping end 14 on the swab head 10 into the outer tube 20, and the plurality of unconnected parts of the conical cylinder portion 142 in the clamping end 14 can elastically avoid the first clamping ring 21 on the outer tube 20 inwardly, so as to facilitate the first clamping ring 21 to be clamped into the first clamping groove 143. The end of the conical cylinder portion 142 away from the cylindrical portion 141 is its tip. After the first clamping ring 21 is clamped with the first clamping groove 143, the tip of the conical cylinder portion 142 extends into the interior of the outer tube 20.

[0019] The inner tube 30 is axially slidably arranged in the outer tube 20, and one end of the inner tube 30 away from the swab head 10 extends to the outside of the outer tube 20 and is fixedly connected with a pressing plate 34. The inner diameter of the end of the inner tube 30 close to the swab head 10 is less than or equal to the inner diameter of the first clamping ring 21. Preferably, a conical guide surface 31 matching the conical surface of the conical cylinder portion 142 is provided inside the end of the inner tube 30 close to the swab head 10. The function of the conical guide surface 31 is to smoothly press the multiple unconnected parts of the conical cylinder portion 142 inward when the inner tube 30 slides close to the swab head 10. A second clamping ring 32 is fixedly provided, and the axial cross-section of the second clamping ring 32 protruding from the inner tube 30 is arc-shaped. The second clamping ring 32 is tightly matched with the inner wall of the outer tube 20, so as to provide a certain sliding damping for the inner tube 30 to prevent misoperation. At the same time, a second clamping groove 22 matching with the second clamping ring 32 is provided on the inner wall of the outer tube 20 to prevent the inner tube 30 from sliding during transportation or storage. In the initial state, the second clamping ring 32 on the inner tube 30 is engaged in the second clamping groove 22 on the outer tube 20, and the inner tube 30 is separated from the tapered cylinder portion 142 in the clamping end 14.

[0020] The plug rod 40 is slidably sleeved in the inner tube 30, the outer tube 20 is provided with a guide slot 23 along its axial direction, the inner tube 30 is provided with an avoidance slot 33 along its axial direction, a connecting rod 42 is fixedly provided on the plug rod 40, the connecting rod 42 passes through the avoidance slot 33 and is slidably arranged in the guide slot 23, and one end of the connecting rod 42 extending to the outside of the outer tube 20 is fixedly connected with a sliding key 43. In the initial state, the end of the plug rod 40 close to the swab head 10 is inserted into the interior of the conical cylinder 142, thereby providing an internal support for the conical cylinder 142, so as to This blocks the multiple unconnected parts of the cone portion 142 from gathering inward, preventing the swab head 10 from falling into the animal body during the sampling process. Furthermore, a third clamping ring 41 is fixedly provided on the outer surface of one end of the plug rod 40 close to the swab head 10. The axial cross-section of the third clamping ring 41 that protrudes from the plug rod 40 is arc-shaped. A third clamping groove 144 that cooperates with the third clamping ring 41 is provided on the inner wall of the cone portion 142. The third clamping ring 41 is engaged in the third clamping groove 144 to prevent the plug rod 40 from sliding during transportation or storage.

[0021] The hoop 50 is clamped on the outside of the outer tube 20, and the bag 60 is also sleeved on the outside of the outer tube 20. One end of the bag 60 is clamped between the outer tube 20 and the hoop 50, and the other end is provided with an elastic band 61.

[0022] When using the sampling swab for sampling, the operator holds the outer tube 20 away from one end of the swab head 10, wears the bag 60 on the arm, and uses the elastic band 61 to tighten the open end of the bag 60 to prevent the operator's arm from contacting the animal to be tested. After wearing, the swab head 10 is inserted into the animal's body through the outer tube 20, and the flocked end 11 on the swab head 10 is used to fully dip the animal's body fluid, and then the swab head 10 with the animal's body fluid is extended into the EP sampling tube. At this time, the sliding key 43 should be slid first to remove the plug rod 40 from the conical cylinder 142, so as to release the inner support effect of the plug rod 40 on the conical cylinder 142. The inner tube 30 is then pushed to slide toward the swab head 10 by the pressing plate 34. As the conical guide surface 31 on the inner tube 30 gradually presses the conical cylinder 142, the multiple unconnected parts of the conical cylinder 142 are forced to gradually gather inward until the outer diameter of the bottom end of the conical cylinder 142 is shrunk to a state smaller than the inner diameter of the first clamping ring 21, so that the swab head 10 is separated from the outer tube 20 and falls into the EP sampling tube for inspection. After the sampling is completed, the bag 60 worn on the arm is turned over to the end of the outer tube 20 that contacts the animal to be tested to prevent the animal body fluids adhering to the outer tube 20 from spreading. Finally, the used sampling swabs are discarded for disposal.

[0023] Embodiment 2: like Figure 6As shown, this embodiment is basically the same as the first embodiment, and the difference is that the outer tube 20 is threadedly connected to the inner tube 30, and the end of the inner tube 30 away from the swab head 10 extends to the outside of the outer tube 20 and is fixedly connected with a knob 35. By rotating the knob 35, the inner tube 30 can be driven to slide axially, and the swab head 10 can also be easily separated from the outer tube 20 and fall into the EP sampling tube. At the same time, during transportation or storage, since the outer tube 20 and the inner tube 30 are threadedly connected, even if the inner tube 30 is squeezed by external force, it is not easy to slip axially. A highly protective sampling swab in this embodiment does not include a plug rod 40 and structures related to the plug rod 40. Therefore, the manufacturing cost of this embodiment is lower than that of the first embodiment.
