Technical Field
[0001] This invention relates to the field of animal disease detection technology, specifically to a semi-automatic urine collector for female cattle used in animal disease detection. Background Technology
[0002] In the fields of animal husbandry, disease prevention and control, and clinical quarantine, urine samples from female cattle are important biological samples for conducting kidney function tests, metabolic analysis, pathogen screening, and detection of toxins and prohibited drug residues. The standardization, convenience, and cleanliness of urine collection directly determine the accuracy of test results and the efficiency of animal disease diagnosis.
[0003] Currently, urine collection from female cattle largely relies on traditional manual methods or simple auxiliary tools. However, in actual large-scale farming, rapid on-site screening, and long-term monitoring, the following technical shortcomings and pain points are commonly observed: First, traditional methods of collecting urine by hand or using ordinary open containers require operators to be close to the cow's hindquarters. Since the vulva of female cattle is located below the anus and is naturally obscured by the tail, manually exposing the vulva requires manually removing the tail. This not only results in a cramped operating space and limited field of vision, but also makes it difficult to ensure the container opening is accurately aligned with the urination area, easily leading to problems such as urine splashing, sample contamination, and insufficient collection volume. Operators face safety risks from being kicked or struck by cattle, making them unsuitable for on-site disease screening of large numbers of animals. Secondly, conventional urine collection devices generally lack adaptive closing and volume control functions. Some urine collection bags with elastic constriction structures tend to close prematurely before reaching the effective collection capacity when a large amount of urine is poured in in a short period, resulting in low utilization of sample storage space. Devices without constriction structures have the problem of urine overflowing and flowing back up, contaminating the urine collection port, damaging sample purity, and affecting the reliability of subsequent disease detection and biochemical analysis results. Overflowing urine tends to accumulate inside the device, making cleaning difficult and resulting in poor hygiene.
[0004] Therefore, developing a semi-automatic urine collector that is adapted to the physiological structure of female cattle, has tail avoidance, precise drainage, gravity-adaptive closing, urine spillage protection, and allows for the separation and reuse of consumables and the main body has become an urgent technical problem to be solved in the field of animal disease detection and clinical quarantine. Summary of the Invention
[0005] The purpose of this invention is to provide a semi-automatic urine collector for detecting female bovine urine in animals, in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a semi-automatic urine collector for detecting female bovine urine in animals, comprising a body and a gravity-sealing assembly. L-shaped hooks are symmetrically fixed to the inner walls of the two sides of the top opening of the body. The gravity-sealing assembly is built into the cavity of the body. The gravity-sealing assembly includes a urine collection bag built into the bottom of the cavity of the body. An arc-shaped shrink ring is integrally fixed to both sides of the top of the urine collection bag, and a groove is provided at the bottom edge of the outer edge of the shrink ring. The shrink ring is sleeved on both ends of a ring-shaped hanging rope, which is then hung between the L-shaped hooks on the inner walls of the two sides of the body.
[0007] Furthermore, the main body of the urine collection bag is located outside the body cavity, and the annular hanging ropes through which the contraction rings on both sides of the top of the urine collection bag are connected to the L-shaped hooks on the inner walls of both sides of the body. As the volume and mass of the main body of the urine collection bag increase with the injection of urine, the contraction rings are automatically closed at both ends of the hanging ropes under the action of gravity as the mass of the urine collection bag increases.
[0008] Furthermore, the inner side of the opening at the bottom of the machine body is provided with an internal thread, and a knob is connected to the inner thread of the internal thread.
[0009] Furthermore, the knob has an axial through-hole in the center, and the inner diameter of the through-hole is smaller than the outer diameter of the urine bag. The knob is surrounded by an overflow hole in a concentric array around the through-hole. After the urine bag reaches its maximum capacity and automatically closes, excess urine is discharged to the outside through the overflow hole.
[0010] Furthermore, a petal-shaped spring is installed around the top of the knob in a ring array around the through hole, and the petal-shaped spring is engaged in the slot provided at the bottom of the outer edge of the shrink ring. The petal-shaped spring itself is elastic and can close the opening along with the closing action of the shrink ring.
[0011] Furthermore, an external thread is provided on the outer side of the opening at the top of the body, and a urine collection cup is connected to the outer thread of the external thread. The outer opening of the urine collection cup is attached to the outer perimeter of the vulva and accommodates the vulva to collect the urine discharged from the vulva.
[0012] Furthermore, a silicone gasket is installed on the outer opening of the urine collection cup, and a urine guide plate is fixedly installed on the inner side of the urine collection cup, with the beveled end of the urine guide plate directly facing the top opening of the urine bag.
[0013] Furthermore, a grip bar is installed on the outside of the machine body, and a handle is fixedly installed at the end of the grip bar.
[0014] Furthermore, the head of the grip is equipped with a cow tail traction assembly, which includes a connecting frame fixedly installed on the head of the grip. The front end notch of the connecting frame is fixed to the outer periphery of the machine body, and a pin is fixed to the rear end plane of the connecting frame. The pin is located directly above the grip connection point, and a traction rod is rotatably installed on the outside of the pin. The traction rod is used to pull the cow tail to the side to fully expose the vulva when collecting urine.
[0015] Furthermore, the cow tail traction assembly also includes a groove at the bottom of the traction rod, a bolt is inserted and fixed to the side of the groove, and a rope loop is hung in the middle of the bolt. A spring rope is fixedly connected to the side of the rope loop, and a rope sleeve is fitted on the outside of the spring rope. A handle is connected to the tail of the rope loop, and the handle is rotatably installed inside the bracket. The bracket is fixed to the outer periphery of the tail of the handle by a clamp.
[0016] This invention provides a semi-automatic urine collector for detecting female bovine urine in animal disease detection, which has the following beneficial effects; 1. This application integrates urine collection, drainage, urine storage, closure, urine spill protection, cow tail avoidance, and handheld operation functions into one unit. It can complete the entire process from vulvar exposure and urine collection to sample sealing without additional auxiliary tools, greatly improving the efficiency of female cow urine sampling. It is suitable for batch animal disease screening, routine quarantine, and clinical testing scenarios.
[0017] 2. This application integrates a handle and a cow tail traction assembly into the whole machine. Operators do not need to be in close contact with the cow's hindquarters. By squeezing the handle, the traction rod can be moved to swing and the cow's tail can be turned to the side to expose the vulva. This avoids the tail obstructing the urine collection and positioning, and reduces the risk of personnel being kicked or swept by the cow's tail. It is suitable for the on-site operation environment of live animal disease detection in farms.
[0018] 3. This application adopts a composite structure of shrink ring, ring-shaped hanging rope and petal spring, which relies on the weight of the urine collection bag to achieve automatic closing. No external power such as electric control or pneumatic is required. The structure is simple and reliable. The petal spring provides elastic damping to prevent premature closing caused by the impact of a large amount of urine in a short time. It maximizes the use of the urine collection bag's design capacity. After it is full, it automatically closes the bag opening to prevent urine from flowing back up and avoid sample contamination and cavity contamination.
[0019] 4. This application adopts a design concept of reusable rigid main body and disposable consumable parts. The structure such as the body, handle, traction component, and knob can be reused multiple times. Only the urine cup and urine bag are discarded after single use as consumables, which reduces the long-term testing cost and avoids the risk of cross-infection of diseases caused by cross-use, and complies with the biosafety standards for animal disease testing.

[0022] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention. Please see Figures 4 to 8This invention provides a technical solution: a semi-automatic urine collector for detecting female bovine urine in animals, comprising a body 1 and a gravity-sealing assembly 3. L-shaped hooks 2 are symmetrically fixed to the inner walls of both sides of the top opening of the body 1. The gravity-sealing assembly 3 is built into the cavity of the body 1 and includes a urine collection bag 301 built into the bottom of the cavity of the body 1. Arc-shaped shrink rings 302 are integrally fixed to both sides of the top of the urine collection bag 301, and a groove 303 is provided at the bottom edge of the outer edge of the shrink rings 302. The shrink rings 302 are fitted onto the ring... The two ends of the loop 304 are attached to the L-shaped hooks 2 on the inner walls of both sides of the body 1. The main body of the urine bag 301 is located outside the cavity of the body 1. The loop 304 through which the shrink rings 302 on both sides of the top of the urine bag 301 are attached to the L-shaped hooks 2 on the inner walls of both sides of the body 1. As the volume and mass of the main body of the urine bag 301 increase with the injection of urine, the shrink rings 302 automatically close at both ends of the loop 304 under the action of gravity. The specific operation is as follows: The slots 303 at the bottom edge of the outer edge of the arc-shaped contraction rings 302 on both sides of the top of the urine collection bag 301 are engaged with the outer side of the petal-shaped spring pieces 8 arranged in a ring around the through hole 6 at the top of the knob 5. The elastic deformation of the petal-shaped spring pieces 8 achieves initial positioning and locking of the contraction rings 302. Then, the knob 5 is tightened through the internal thread 4 of the opening at the bottom of the machine body 1 to complete the limiting installation of the lower part of the urine collection bag 301. The annular hanging rope 304, fitted onto the contraction rings 302, is then hung on the L-shaped hooks 2 symmetrically arranged on the inner walls on both sides of the opening at the top of the machine body 1. Between these, the urine collection bag 301 is suspended and positioned inside the cavity of the body 1, and the main body of the urine collection bag 301 naturally extends to the outside of the cavity of the body 1 to expand the urine storage space. The urine cup 10 is screwed and fixed to the external thread 9 on the top of the body 1 through the inner thread. The silicone gasket 11 on the outer opening of the urine cup 10 forms a flexible contact surface. The inclined end of the inner urine guide plate 12 is precisely aligned with the top opening of the urine collection bag 301 to form a complete flow channel. Finally, the outer periphery of the body 1 is fixed to the front notch of the connecting frame 1501 to achieve an integrated connection with the handle 13. Please see Figures 4 to 8The bottom opening of the body 1 has an internal thread 4, and a knob 5 is threaded inside the internal thread 4. A through hole 6 is axially passed through the center of the knob 5, and the inner diameter of the through hole 6 is smaller than the outer diameter of the urine bag 301. Urine overflow holes 7 are concentrically arranged around the through hole 6 around the knob 5. After the urine bag 301 reaches its maximum capacity and automatically closes, excess urine is discharged to the outside through the urine overflow holes 7. Petal springs 8 are installed in a ring array around the top of the knob 5 around the through hole 6, and the petal springs 8 are engaged with the groove 303 at the bottom edge of the shrink ring 302. Inside, the petal spring 8 itself is elastic and can close the opening along with the closing action of the contraction ring 302. The outer side of the top opening of the body 1 is provided with an external thread 9, and the outer thread of the external thread 9 is connected to a urine cup 10. The outer opening of the urine cup 10 is attached to the outer perimeter of the vulva and accommodates the vulva to collect the urine discharged from the vulva. A silicone gasket 11 is installed on the outer opening of the urine cup 10, and a urine guide plate 12 is fixedly installed on the inner side of the urine cup 10. The inclined end of the urine guide plate 12 is directly connected to the top opening of the urine bag 301. The specific operation is as follows: When a female calf urinates, the urine flows through the urethra into the reproductive vestibule, and then out through the vulva into the urine collection cup 10. The urine slides down along the urine guide plate 12, which is inclined inside the urine collection cup 10, and is precisely guided into the opening at the top of the urine collection bag 301, completing the urine collection and storage. The main body of the urine collection bag 301 is placed outside the cavity of the machine body 1, which can significantly increase the single urine capacity and meet the sample volume requirements for animal disease testing. As urine is continuously injected, the volume and overall mass of the urine collection bag 301 gradually increase. Under its own gravity, it pulls down the two sides of the contraction ring 302. The contraction ring 302 slides along the two ends of the annular hanging rope 304 towards the center, creating a closing tendency. At the same time, the contraction ring 302 is engaged with the petal spring 8 through the slot 303. The petal spring 8 itself has elasticity, which provides elastic resistance to the closing action of the contraction ring 302, offsetting the instantaneous pulling force caused by the short-term large amount of urine, and preventing the urine collection bag 301 from failing to reach its design capacity. The urine collection bag 301 is closed slowly and smoothly only when the overall weight of the urine collection bag 301 continues to accumulate and increase. When the urine in the urine collection bag 301 reaches its maximum capacity, the contraction ring 302 completely closes to seal the top opening of the urine collection bag 301, preventing urine from continuing to enter. The excess urine then collects in the urine collection cup 10 and the cavity of the body 1 and is discharged outward through the overflow holes 7 set in the concentric array on the knob 5. This avoids urine backflow, leakage or contamination of the inside of the urine collection cup 10 due to excessive pressure. This application adopts a composite structure of contraction ring 302, ring-shaped hanging rope 304 and petal spring 8. It relies on the weight of the urine collection bag 301 to achieve automatic closure. No external power such as electric control or pneumatic is required. The structure is simple and reliable. The petal spring 8 provides elastic damping to prevent premature closure caused by a large amount of urine impact in a short time. It maximizes the use of the designed capacity of the urine collection bag 301. After it is full, the bag opening is automatically closed to prevent urine backflow and avoid sample contamination and cavity contamination. Please seeFigures 1 to 3 The machine body 1 has a handle 13 installed on its exterior, and a handle 14 is fixedly installed at the end of the handle 13. A cow tail traction assembly 15 is installed at the head of the handle 13. The cow tail traction assembly 15 includes a connecting frame 1501 fixedly installed at the head of the handle 13. The front end notch of the connecting frame 1501 is fixed to the outer periphery of the machine body 1, and a pin 1502 is fixed to the rear end plane of the connecting frame 1501. The pin 1502 is located directly above the connection point of the handle 13, and a traction rod 1503 is rotatably installed on the outside of the pin 1502. The traction rod 1503 is used to pull the cow tail to the side when collecting urine. The traction offset is used to fully expose the vulva. The cow tail traction assembly 15 also includes a groove 1504 opened at the bottom end of the traction rod 1503. A bolt 1505 is inserted and fixed at the side end of the groove 1504, and a rope ring 1506 is hung in the middle of the bolt 1505. A spring rope 1507 is fixedly connected to the side end of the rope ring 1506, and a rope sleeve 1508 is sleeved on the outside of the spring rope 1507. A handle 1509 is connected to the tail end of the rope ring 1506, and the handle 1509 is rotatably installed inside the bracket 1510. The bracket 1510 is fixed to the outer periphery of the tail end of the handle 13 by a clamp. The specific operation is as follows: The operator holds the handle 14 at the end of the handle 13 and extends the urine collector towards the vulva of the female cow's hindquarters. The operator squeezes the handle 1509 at the end of the handle 13, which pulls the rope loop 1506 through the spring rope 1507. This causes the traction rod 1503 to swing to the side around the pin 1502, pulling the cow's tail to the side and removing the tail from obstructing the vulva, thus fully exposing the vulva area. Then, the outer opening of the urine collection cup 10 is placed against the outer perimeter of the cow's vulva, covering the vulva inside the urine collection cup 10 to form a closed urine collection area. This application integrates the handle 13 and the cow tail traction component 15 into the whole machine. The operator does not need to be in close contact with the cow's hindquarters. By squeezing the handle 1509, the operator can link the traction rod 1503 to swing and turn the cow's tail to the side to expose the vulva, avoiding the tail from obstructing the urine collection positioning. At the same time, it reduces the risk of the operator being kicked or swept by the cow's tail, making it suitable for the on-site operation environment of live animal disease testing in farms.
[0023] In summary, when using this semi-automatic urine collector for female cattle used in animal disease testing: First, the slots 303 at the bottom of the outer edges of the arc-shaped contraction rings 302 on both sides of the top of the urine collection bag 301 are engaged with the outer side of the petal-shaped spring pieces 8 arranged in a ring around the through hole 6 at the top of the knob 5. The elastic deformation of the petal-shaped spring pieces 8 is used to achieve the initial positioning and locking of the contraction rings 302. Then, the knob 5 is tightened and fixed by the internal thread 4 of the bottom opening of the machine body 1, completing the limiting installation of the lower part of the urine collection bag 301. The annular hanging rope 304, which is sleeved on the contraction rings 302, is hung between the L-shaped hooks 2 symmetrically arranged on the inner walls on both sides of the top opening of the machine body 1. The urine collection bag 301 is suspended and positioned inside the cavity of the body 1, and the main body of the urine collection bag 301 naturally extends to the outside of the cavity of the body 1 to expand the urine storage space. The urine cup 10 is screwed and fixed to the external thread 9 on the top of the body 1 through the inner thread. The silicone gasket 11 on the outer opening of the urine cup 10 forms a flexible contact surface. The inclined end of the inner urine guide plate 12 is precisely aligned with the top opening of the urine collection bag 301 to form a complete flow channel. Finally, the outer periphery of the body 1 is fixed to the front notch of the connecting frame 1501 to achieve an integrated connection with the handle 13. Secondly, during use, the operator holds the handle 14 at the end of the handle 13 and extends the urine collector towards the vulva of the female cow's hindquarters. By squeezing the handle 1509 at the end of the handle 13, the operator pulls the rope loop 1506 through the spring rope 1507, which in turn causes the traction rod 1503 to swing to the side around the pin 1502, pulling the cow's tail to the side and removing the tail from obstructing the vulva, thus fully exposing the vulva area. Then, the outer opening of the urine collection cup 10 is placed against the outer perimeter of the cow's vulva, covering the vulva inside the urine collection cup 10 to form a closed urine collection area. This application integrates the handle 13 and the cow tail traction component 15 into the whole machine. The operator does not need to be in close contact with the cow's hindquarters. By squeezing the handle 1509, the operator can link the traction rod 1503 to swing and turn the cow's tail to the side to expose the vulva, avoiding the tail from obstructing the urine collection positioning. At the same time, it reduces the risk of the operator being kicked or swept by the cow's tail, making it suitable for the on-site operating environment of live animal disease testing in farms. Then, when the female calf urinates, the urine flows through the urethra into the reproductive vestibule, and then out through the vulva into the urine collection cup 10. The urine slides down along the urine guide plate 12, which is inclined inside the urine collection cup 10, and is guided to flow precisely into the top opening of the urine collection bag 301, completing the urine collection and storage. The main body of the urine collection bag 301 is placed outside the cavity of the machine body 1, which can greatly increase the single urine capacity and meet the sample volume requirements for animal disease testing. As urine is continuously injected, the volume and overall mass of the urine collection bag 301 gradually increase. Under its own gravity, it pulls down the two sides of the contraction ring 302. The contraction ring 302 slides along the two ends of the ring-shaped hanging rope 304 towards the center, creating a closing tendency. At the same time, the contraction ring 302 is engaged with the petal spring 8 through the slot 303. The petal spring 8 itself is elastic, providing elastic resistance to the closing action of the contraction ring 302, offsetting the instantaneous pulling force caused by the short-term large amount of urine, and preventing the urine collection bag 301 from prematurely reaching its design capacity. The rapid closing mechanism overcomes elastic resistance to achieve a slow and stable closing only when the overall weight of the urine collection bag 301 continues to accumulate and increase. When the urine in the urine collection bag 301 reaches its maximum capacity, the contraction ring 302 completely closes to seal the top opening of the urine collection bag 301, preventing urine from continuing to enter. Subsequent excess urine collects in the urine collection cup 10 and the cavity of the machine body 1, and is discharged outward through the overflow holes 7 set in a concentric array on the knob 5, avoiding urine backflow, leakage, or contamination of the inside of the urine collection cup 10 due to excessive pressure. This application adopts a composite structure of contraction ring 302, ring-shaped hanging rope 304, and petal spring 8, which relies on the weight of the urine collection bag 301 to achieve automatic closing. No external power such as electric control or pneumatic is required. The structure is simple and reliable. The petal spring 8 provides elastic damping to prevent premature closing caused by a large amount of urine impact in a short period of time, maximizing the use of the designed capacity of the urine collection bag 301. After being full, the bag opening is automatically closed to prevent urine backflow and avoid sample contamination and cavity contamination. Finally, after urine collection is completed, unscrew and disassemble the urine collection cup 10 and discard it. Remove the loop rope 304 from the L-shaped hook 2, unscrew the knob 5, and take out the used urine collection bag 301 for testing or disposal. The rigid structures such as the body 1, handle 13, cow tail traction component 15, and knob 5 are not contaminated by urine or can be easily cleaned and reused. Subsequent testing only requires replacing the urine collection cup 10 and urine collection bag 301. This application adopts the design concept of reusable rigid body and disposable consumable parts. The structure such as the body 1, handle 13, traction component, and knob 5 can be recycled multiple times. Only the urine collection cup 10 and urine collection bag 301 are discarded after a single use as consumables, which reduces long-term testing costs and avoids the risk of cross-infection of diseases caused by cross-use, which complies with the biosafety standards for animal disease testing.
