Technical Field

[0001] The utility model relates to the technical field of bird virus detection, in particular to a bird West Nile virus and avian influenza virus sampling device. Background Art

[0002] West Nile virus and avian influenza virus are currently common infectious viruses that use birds as hosts. Both viruses are contagious and lethal, and pose a high risk to the bird farming industry. Therefore, it is necessary to conduct virus testing on newly introduced birds.

[0003] An easy-to-clean storage device for avian influenza virus sampling and detection disclosed in the Chinese invention patent application disclosure CN 212290898 U includes a storage box, a cover body of which is installed through a mounting structure, a handle and a sealing rubber are fixedly installed on the cover body, and the sealing rubber is located inside the storage box, a placement groove is fixedly installed inside the storage box, a storage seat is placed on the placement groove, and the storage seat is made of a material with good thermal conductivity, an insulation cover is provided on the storage seat, a plurality of storage grooves and a groove 2 are provided on the storage seat, an electric heating tube and a heat conducting plate are placed on the placement groove, and the lower surface of the heat conducting plate is in contact with the electric heating tube, and a positioning structure is provided between the storage seat and the storage box.

[0004] This technical solution has the advantage that the heat generated by the electric heating tube can be used to sterilize and clean the storage seat and the interior of the storage box after each use, thereby improving the overall safety during use. The storage seat can also be removed regularly for more thorough sterilization and cleaning. However, cotton swabs are often used to dip the sample in the virus sampling process. This operation method has a low operating cost, but the exposed cotton swab will be contaminated by other test cotton swabs. At the same time, in order to sample two viruses simultaneously for separate testing, double-headed cotton swabs are commonly used. The two ends of the double-headed cotton swabs are the same shape and size, which can be easily confused. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the utility model provides a device for sampling West Nile virus and avian influenza virus in birds, which solves the problem that the sampling cotton swab is easily contaminated in the background technology.

[0006] Technical Solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a device for sampling West Nile virus and avian influenza virus in birds, comprising a sampling rod, with sampling cotton heads provided at both ends of the sampling rod, a sleeve slidably connected to the surface of the sampling rod, the sleeve being sleeved on the outer surface of the sampling cotton head, a tooth groove being provided on the inner ring of the sleeve, a tooth ring being symmetrically fixedly installed on the outer surface of the sampling rod, a baffle being fixedly installed on the side of the sampling rod away from the tooth ring, the sleeve being restricted between the tooth ring and the baffle, and the sleeves at both ends being painted with different colors.

[0008] Furthermore, the outer surface of one of the sleeves is vacant with a triangular marking point, and the outer surface of the other sleeve is vacant with a circular marking point.

[0009] Furthermore, a sampling cotton head is provided at one end of the sampling rod, and an end of the sampling rod away from the sampling cotton head is fixedly installed with equally distributed protrusions, and the gaps between the protrusions are equidistant from the thickness of the protrusions. The outer surface of the sampling rod is sleeved with a hand-held sleeve, and a groove for accommodating the protrusions is provided inside the hand-held sleeve. All the grooves are connected and penetrated by a through groove on one side, and the protrusions are slidably connected inside the grooves.

[0010] Furthermore, sampling rods are inserted into both ends of the handheld sleeve, and the cross-sectional shape and size of the through groove are the same as the size of the protrusion.

[0011] Furthermore, one end of the hand-held sleeve is provided with a horizontal friction groove parallel to the axis of the hand-held sleeve, and the other end of the hand-held sleeve is provided with an annular friction groove concentric with the hand-held sleeve.

[0012] Furthermore, when the sleeve is located between the toothed ring and the baffle at one end away from the sampling cotton head, the sleeve completely exits the sampling cotton head; when the sleeve is located between the toothed ring and the baffle at one end close to the sampling cotton head, the sleeve completely wraps the sampling cotton head.

[0013] Furthermore, an end cover is sleeved on the outer side of the sleeve.

[0014] The beneficial effects of the present invention are:

[0015] 1. The bird West Nile virus and avian influenza virus sampling device allows the sampling cotton head to leak out by sliding the sleeve at one end toward the middle, and the position of the sleeve can be limited by the tooth ring and the baffle. The sampling rod can be held for sampling. After sampling, the sleeve is reset and the end cover is added. This setting can prevent the sampling cotton head from being contaminated, and the other end can be used for repeated actions.

[0016] 2. The bird West Nile virus and avian influenza virus sampling device is provided with a sampling cotton head at one end of a sampling rod, and the end of the sampling rod away from the sampling cotton head is fixedly mounted with equally distributed protrusions, and the gaps between the protrusions are equidistant from the thickness of the protrusions. The outer surface of the sampling rod is sleeved with a hand-held sleeve, and the interior of the hand-held sleeve is provided with grooves for accommodating the protrusions. All the grooves are connected and penetrated by a through groove on one side, and the protrusions are slidably connected to the inside of the grooves. Through such a setting, the sampling rod can be rotated so that the protrusions withdraw from the grooves and extend outward for a certain length, and then the protrusions are clamped in the corresponding grooves again, thereby changing the length of the sampling rod, and thus being able to adapt to the requirements for different lengths of sampling rods in different environments.

[0017] 3. The bird West Nile virus and avian influenza virus sampling device can visually indicate the direction of the two ends by painting different colors on the sleeves at both ends and painting different shapes when painting the colors on the sleeves. It can also indicate the direction of the two ends by tactilely providing annular friction grooves and horizontal friction grooves. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0025] See Figure 1-Figure 5A device for sampling West Nile virus and avian influenza virus in birds comprises a sampling rod 1, sampling cotton heads 2 are provided at both ends of the sampling rod 1, a sleeve 3 is slidably connected to the surface of the sampling rod 1, the sleeve 3 is sleeved on the outer surface of the sampling cotton head 2, a tooth groove 4 is provided on the inner ring of the sleeve 3, a tooth ring 6 is symmetrically fixedly installed on the outer surface of the sampling rod 1, the tooth ring 6 can undergo elastic deformation for the passage of the sleeve 3, a baffle 7 is fixedly installed on the side of the sampling rod 1 away from the tooth ring 6, the sleeve 3 is restricted between the tooth ring 6 and the baffle 7, and the sleeves 3 at both ends are painted with different colors.

[0026] The outer surface of one sleeve 3 is missing a triangular marking point 13, and the outer surface of the other sleeve 3 is missing a circular marking point 13. Such shape marking can prevent color-blind operators from being unable to accurately identify colors and thus unable to identify the specific sampling content of the double heads.

[0027] A sampling cotton head 2 is provided at one end of the sampling rod 1, and an end of the sampling rod 1 away from the sampling cotton head 2 is fixedly installed with equidistantly distributed protrusions 14, and the gaps between the protrusions 14 are equidistant from the thickness of the protrusions 14. A hand-held sleeve 8 is sleeved on the outer surface of the sampling rod 1, and a groove 9 for accommodating the protrusions 14 is provided inside the hand-held sleeve 8. All the grooves 9 are connected and penetrated by a through groove 15 on one side, and the protrusions 14 are slidably connected to the inside of the grooves 9. Through such an arrangement, the sampling rod 1 can be rotated so that the protrusions 14 withdraw from the grooves 9 and extend outward for a certain length, and then the protrusions 14 can be clamped in the corresponding grooves 9 again, thereby changing the length of the sampling rod 1 and adapting to the requirements for different lengths of the sampling rod 1 in different environments.

[0028] The sampling rods 1 are inserted into both ends of the handheld sleeve 8 , and the cross-sectional shape and size of the through groove 15 are the same as the size of the protrusion 14 . This arrangement enables the protrusion 14 to slide inside the through groove 15 .

[0029] One end of the handheld sleeve 8 is provided with a horizontal friction groove 10 parallel to the axis of the handheld sleeve 8, and the other end of the handheld sleeve 8 is provided with an annular friction groove 11 concentric with the handheld sleeve 8. Through this arrangement, different sampling directions can be perceived by touch.

[0030] When the sleeve 3 is located between the toothed ring 6 and the baffle 7 away from one end of the sampling cotton head 2, the sleeve 3 completely withdraws from the sampling cotton head 2. When the sleeve 3 is located between the toothed ring 6 and the baffle 7 close to one end of the sampling cotton head 2, the sleeve 3 completely wraps the sampling cotton head 2. This arrangement can better protect the sampling cotton head 2.

[0031] The outer side of the sleeve 3 is sleeved with an end cap 12 , and after the setting is completed, the sampling cotton head 2 can be prevented from being contaminated by covering the end cap 12 .

[0032] During use, the sampling cotton tip 2 can be released by sliding the sleeve 3 at one end toward the middle. The position of the sleeve 3 can be controlled by the toothed ring 6 and the baffle 7. The sampling rod 1 can be held for sampling. After sampling, the sleeve 3 is reset and the end cap 12 is added. This arrangement can prevent the sampling cotton tip 2 from being contaminated. Repeat the operation to use the other end.

[0033] When sampling requires the sampling rod 1 to be longer, the sampling rod 1 is rotated so that the protrusion 14 exits the groove 9 and then slides outward in the through groove 15. After sliding to the specified length, it is rotated again so that the protrusion 14 is plugged into the corresponding groove 9, thereby changing the length of the extended sampling rod 1 extending out of the handheld sleeve 8, and thus changing the overall length.

[0034] By painting different colors on the sleeves 3 at both ends, and painting different shapes when painting the colors on the sleeves 3, the directions of the two ends can be visually prompted. By setting the annular friction groove 11 and the horizontal friction groove 10, the directions of the two ends can be tactilely prompted.

[0035] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
