Description

Technical Field

[0001] This utility model relates to the field of veterinary equipment technology, specifically to a bovine vaginal secretion collection device. Background Technology

[0002] The current situation regarding livestock abortion is not optimistic, and the prevention and control of brucellosis (hereinafter referred to as brucellosis) in livestock is also not optimistic. Various regions are carrying out investigations on the causes of livestock abortion, etiological testing, and brucellosis pathogen testing. One of the more direct and effective samples is vaginal secretions from female animals.

[0003] Traditional sampling typically involves veterinarians inserting medical or vaginal swabs into the cow's vagina to absorb secretions, and then placing the swab into a sterile container. There is a brief exposure period between the swab being removed from the vagina and entering the container, during which the swab tip may come into contact with dust or other external impurities in the environment, increasing the risk of sample contamination.

[0004] Therefore, in view of this, we have studied and improved the existing structure and proposed a bovine vaginal secretion collection device. Utility Model Content

[0005] The purpose of this invention is to provide a bovine vaginal secretion collection device to solve the problem that sampling swabs are directly exposed and easily affected by external dust during the process from sampling to entering the storage container.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bovine vaginal secretion collection device, comprising a collection box, a movable rod slidably connected to the rear side of the outer surface of the collection box, a fixed plate fixedly installed on the surface of the movable rod inside the rear side of the collection box, a spring fixedly installed on the front side of the fixed plate, a push plate fixedly connected to the front end of the spring, connecting plates rotatably installed on both the left and right sides of the front surface of the push plate, and grooves formed on both the left and right sides of the front surface of the inner surface of the collection box, with a closing plate rotatably installed on the inner surface of each groove.

[0007] Preferably, the spring is sleeved on the outside of the movable rod, and the front end of the movable rod slides through the push plate.

[0008] Preferably, the push plate slides and fits against the inner surface of the storage box around its perimeter, and the front end of the connecting plate is rotatably connected to the closing plate.

[0009] Preferably, spring pieces are fixedly installed on both the left and right sides of the front end of the movable rod, and the spring pieces are set as semi-circular shapes with opposite concave surfaces.

[0010] Preferably, the outer surface of the spring sheet is provided with threaded texture, and the spring sheet is inclined to the left and right sides.

[0011] Preferably, a movable ring is slidably sleeved on the front side of the movable rod surface. The inner diameter of the movable ring matches the diameter of the movable rod, and the inner circular surface of the movable ring is provided with a thread pattern that matches the thread pattern on the surface of the spring piece.

[0012] Preferably, the front end of the movable rod is provided with a sampling swab, and the rear end of the sampling swab is located inside the arc-shaped surface of the two side springs, and the diameter of the sampling swab is matched with the movable rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the cooperation of the movable rod, fixed plate, spring, push plate, connecting plate, groove and sealing plate, pushing the movable rod can open the front opening of the storage box and extend the sampling swab; when the movable rod is pulled back, the sampling swab first retracts into the storage box, and then the sealing plate closes and blocks the front opening of the storage box, thereby reducing the direct exposure of the sampling swab to the external environment during the retrieval and transportation process, and reducing the risk of sample contamination caused by dust adhesion; 2. The combination of spring clips, threaded texture, and movable rings allows for the clamping and fixing of the sampling swabs, and facilitates the replacement of the sampling swabs.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0017] like Figures 1-4As shown, a bovine vaginal secretion collection device includes a collection box 1. A movable rod 2 is slidably connected to the rear side of the outer surface of the collection box 1. A fixing plate 3 is fixedly installed on the surface of the movable rod 2 inside the rear side of the collection box 1. A spring 4 is fixedly installed on the front side of the surface of the fixing plate 3. A push plate 5 is fixedly connected to the front end of the spring 4. Connecting plates 6 are rotatably installed on both the left and right sides of the front surface of the push plate 5. Grooves 7 are opened on both the left and right sides of the front side of the inner surface of the collection box 1. A closing plate 8 is rotatably installed on the inner surface of each groove 7. The spring 4 is sleeved on the outside of the movable rod 2, and the front end of the movable rod 2 slides through the push plate 5. The push plate 5 slides against the inner surface of the collection box 1 around its perimeter. The front end of the connecting plate 6 is rotatably connected to the closing plate 8.

[0018] When the movable rod 2 moves forward, it pushes the spring 4 using the fixed plate 3. The spring 4, under its own elastic support, pushes the propulsion plate 5 forward. The propulsion plate 5, through the connecting plate 6, pushes the closing plate 8 to rotate forward, thereby opening the front opening of the storage box 1. The opened closing plate 8 can move the cow's labia to both sides, making it easier to expose the vaginal opening.

[0019] The movable rod 2 carries the sampling swab 12 forward. After the sealing plate 8 is opened, its two sides are limited by the groove 7 and stop rotating, causing the push plate 5 to stop moving forward. When the movable rod 2 is pushed, the fixing plate 3 compresses the spring 4, causing the movable rod 2 to continue to move forward relative to the push plate 5. The sampling swab 12 extends from the front end of the storage box 1 and enters the cow's vagina to absorb secretions.

[0020] After sampling is completed, pull the movable rod 2 backward. The sampling swab 12 retracts with the movable rod 2 and enters the storage box 1. As the movable rod 2 moves backward, the fixed plate 3 drives the spring 4 to gradually return to its original length. When the spring 4 returns to its natural length, continue pulling the movable rod 2. The spring 4 generates a backward pulling force on the push plate 5, causing the push plate 5 to drive the closing plate 8 to rotate in the closing direction through the connecting plate 6. Thus, the sampling swab 12 enters the storage box 1 first, and the closing plate 8 closes subsequently, blocking the front opening of the storage box 1. This prevents the closing plate 8 from closing prematurely and jamming the sampling swab 12, and reduces the direct exposure of the sampling swab 12 to the external environment during transportation.

[0021] Furthermore, spring pieces 9 are fixedly installed on both the left and right sides of the front end of the movable rod 2. The spring pieces 9 are set in a semi-circular shape with opposite concave surfaces. Threaded patterns 10 are formed on the outer surface of the spring pieces 9, and the spring pieces 9 are inclined to the left and right sides. A movable ring 11 is slidably fitted on the front side of the surface of the movable rod 2. The inner diameter of the movable ring 11 matches the diameter of the movable rod 2, and the inner circular surface of the movable ring 11 is provided with threaded patterns 10 that cooperate with the threaded patterns 10 on the surface of the spring pieces 9. A sampling swab 12 is provided at the front end of the movable rod 2. The rear end of the sampling swab 12 is located inside the arc-shaped surface of the spring pieces 9 on both sides, and the diameter of the sampling swab 12 matches that of the movable rod 2.

[0022] The sampling swab 12 is inserted between the two spring pieces 9. After the movable ring 11 is pushed into contact with the threaded pattern 10, the movable ring 11 is rotated. The movable ring 11 gradually moves forward along the thread and squeezes the spring pieces 9 to contract towards the center, thereby clamping and fixing the sampling swab 12. After the movable ring 11 is rotated in the opposite direction to disengage it from the spring pieces 9, the spring pieces 9 expand again under the action of elasticity, releasing the clamp on the sampling swab 12, and the sampling swab 12 can be removed. The rotation operation of the movable ring 11 is used for the installation or removal of the sampling swab 12. It is not necessary to rotate the movable ring 11 during the actual sampling advance and retraction process.

[0023] During operation, first, place the collection box 1 against the cow's vulva, aligning the gap in the middle of the sealing plate 8 with the vaginal opening. Push the movable rod 2 to open the sealing plate 8 and allow the sampling swab 12 to extend from the collection box 1 and enter the vagina to absorb secretions. After sampling, pull the movable rod 2 backward to retract the sampling swab 12 into the collection box 1, and then close the sealing plate 8 to block the front opening of the collection box 1. During testing, push the movable rod 2 again to extend the sampling swab 12, and rotate the movable ring 11 in the opposite direction to release the clamp and remove the sampling swab 12. When installing a new sampling swab 12, insert its rear end between the two side spring clips 9, and rotate the movable ring 11 to retract and clamp the spring clips 9.
