Description

Technical Field

[0001] The present invention relates to a sampling swab, and particularly to an adjustable sampling swab for animal disease detection. Background Art

[0002] Endometritis is considered to be the most important reproductive system disease of large female livestock such as current dairy cows, which can cause female livestock unable to conceive, reduced reproductive rate, and decreased milk production. In addition, its treatment cost is expensive, causing huge economic losses to enterprises and even the entire industry. Respiratory infectious viral diseases and bacterial diseases such as bovine infectious rhinotracheitis, bovine respiratory syncytial virus infection, equine influenza, and equine streptococcal pneumonia also pose a greater threat to the health of large livestock.

[0003] Currently, cotton swabs are generally used for sampling large animals in China. Its advantages are low price and easy availability. However, its defects are also obvious, that is, the sampling efficiency is low, the length of the swab cannot meet the sampling of deep structures of large animals (such as inside the uterus or deep in the upper respiratory tract), and it is easily contaminated by the outside world. In recent years, China has been attaching great importance to animal disease monitoring work, and sample collection is crucial as the initial step in carrying out laboratory detection and diagnosis work.

[0004] Currently, when using sampling swabs for animal disease detection, there are still some defects and deficiencies. The specific areas that need to be improved are as follows: Due to the uterine structure, when collecting samples inside the uterus, the sampling swab must pass through the vagina, which has the risk of bringing vaginal flora into the uterus, causing uterine infection, and the head of the swab is easily contaminated by vaginal flora before use. The anatomical structure of the upper respiratory tract of animals is relatively complex, and the nerve distribution of its epithelial tissue is rich and sensitive. The sampling swab must pass through the oral cavity and laryngopharynx into the upper respiratory tract. The rich saliva, food residues, digestive enzymes, and bacteria in the oral cavity may also contaminate the head of the swab, thus affecting the test results. Summary of the Invention

The upper surface of the upper clamping plate 11 is simultaneously fixedly connected to the bottom ends of two second telescopic rods 13 and two second springs 12. The upper ends of the two second telescopic rods 13 and the two second springs 12 are all fixedly connected to the upper end of the support frame 14. The two second springs 12 are respectively sleeved on the outer sides of the two second telescopic rods 13. The bottom end of the support frame 14 is fixedly connected to the right end face of the fixed column 8. When using the device to sample the uterine cavity of livestock, the user can push the upper clamping plate 11 upward to squeeze the second telescopic rods 13 and the second springs 12, and pass the sealing cylinder 4 through between the upper clamping plate 11 and the lower clamping plate 10, and pass the sealing cylinder 4 through the connecting hole and the first sleeve hole 27, and make the left end of the sealing cylinder 4 abut against the sealing baffle 23. At this time, release the upper clamping plate 11 and use the elastic force of the second spring 12 to push the upper clamping plate 11 downward to clamp and fix the sealing cylinder 4, so as to limit and fix the sealing cylinder 4 by using the upper clamping plate 11 and the lower clamping plate 10, and avoid the sealing cylinder 4 sliding during the sampling process and affecting the sampling efficiency.

[0027] The rotating shaft 18 is also rotatably connected to the middle of the first rotating disc 6 through a sealed bearing, and the left end of the rotating shaft 18 extends between the first rotating disc 6 and the second rotating disc 7. The left end of the rotating shaft 18 is fixedly connected to the upper end of the sealing baffle 23. The left side surface of the sealing baffle 23 abuts against the left inner side surface of the second rotating disc 7. A first sleeve hole 27 corresponding to the sealing baffle 23 is formed in the second rotating disc 7. By arranging the sealing baffle 23 corresponding to the first sleeve hole 27, the first sleeve hole 27 is sealed by the sealing baffle 23, so as to prevent the liquid inside the livestock vagina from flowing into the inside of the outer cylinder 3 through the first sleeve hole 27 and contaminating the sampling rod 29 subsequently when the outer cylinder 3 is inserted into the livestock vagina. The user inserts the left ends of the outer cylinder 3 and the inner cylinder 1 into the livestock vagina to an appropriate depth. At this time, the user can rotate the worm 16 to drive the rotating shaft 18 and the sealing baffle 23 to rotate 180 degrees by means of the worm gear 15, so that the sealing baffle 23 deviates from the first sleeve hole 27, and then the sampling rod 29 can be extended from the second sleeve hole 32 and the first sleeve hole 27 for sampling.

[0028] A second sleeve hole 32 corresponding to the first sleeve hole 27 is formed in the first rotating disc 6. The second sleeve hole 32 is sleeved with a sealing cylinder 4. A sampling rod 29 is sleeved inside the sealing cylinder 4. A cotton fiber rod is arranged at the left end of the sampling rod 29. A breaking groove 30 is formed on the left side of the sampling rod 29.

[0029] The right end of the sampling rod 29 is fixedly connected to the left end of a screw rod 5. The screw rod 5 is in threaded connection with a threaded groove formed on the right end of the inner side surface of the sealing cylinder 4. A sealing film 31 is fixedly arranged at the left end of the inner side surface of the sealing cylinder 4.

The left end of the positioning rod 28 is fixedly connected to the left inner side surface of the second rotating disc 7. By forming the positioning hole 22 on the first rotating disc 6 and arranging the positioning rod 28 on the second rotating disc 7 to be sleeved with the positioning hole 22, the outer cylinder 3 is positioned by the positioning rod 28 and the positioning hole 22 when the outer cylinder 3 and the inner cylinder 1 are sleeved, so as to ensure that the first sleeve hole 27 and the second sleeve hole 32 are kept corresponding.

[0031] The operation steps of the present invention are as follows: When using this device to sample the uterine cavity of livestock, the user can push the upper clamping plate 11 upward to squeeze the second telescopic rod 13 and the second spring 12, and pass the sealing cylinder 4 through between the upper clamping plate 11 and the lower clamping plate 10, and pass the sealing cylinder 4 through the connecting hole and the first sleeve hole 27, and make the left end of the sealing cylinder 4 abut against the sealing baffle 23. At this time, release the upper clamping plate 11 and use the elastic force of the second spring 12 to push the upper clamping plate 11 downward to clamp and fix the sealing cylinder 4. Then the user inserts the left ends of the outer cylinder 3 and the inner cylinder 1 into the appropriate depth of the livestock vagina. At this time, the user can rotate the worm 16 to drive the worm wheel 15 to drive the rotating shaft 18 and the sealing baffle 23 to rotate 180 degrees, so that the sealing baffle 23 deviates from the first sleeve hole 27; At this time, the user can rotate the screw rod 5 to make the screw rod 5 move inside the left sealing cylinder 4. When the screw rod 5 moves to the left, it pushes the sampling rod 29 to move to the left, so that the sampling rod 29 pierces the sealing film 31, and the cotton fiber rod at the left end of the sampling rod 29 extends out of the first sleeve hole 27 to contact the uterine cavity wall of the livestock. At this time, the user can control the motor 20 to work, and drive the first rotating disk 6, the second rotating disk 7, the sealing cylinder 4 and the sampling rod 29 to rotate by means of the gear 21 and the internal gear ring 19, so that the sampling rod 29 rotates while fitting the uterine cavity wall of the livestock for sampling. After sampling, the screw rod 5 can be rotated in the reverse direction to make the sampling rod 29 move to the right and retract into the sealing cylinder 4; Then the user can take out the outer cylinder 3 and the inner cylinder 1 from the livestock vagina, and then pull the upper clamping plate 11 upward to take out the sealing cylinder 4 from the inner cylinder 1. During detection, the sampling rod 29 can be taken out from the sealing cylinder 4, and the sampling rod 29 can be broken at the breaking groove 30. Then the user can pull the first fixing plate 201 to the right to stretch the first telescopic rod 203 and the first spring 204, so that the limiting rod 207 disengages from the limiting hole 25, and then rotate the first fixing plate 201. After the connecting frame 206 corresponds to the slot 24, pull the outer cylinder 3 to the right so that the connecting frame 206 passes through the slot 24 to remove the outer cylinder 3 from the connecting groove 9 for disassembling the outer cylinder 3.
