[0036] Furthermore, in the description of the present invention, unless otherwise specified, “plurality”, “multiple roots”, and “multiple groups” mean two or more.

[0037] like Figure 1-Figure 6 As shown, an embodiment of the present invention provides a cow urine collection device, comprising a urine mask 6 and a urine collecting bag 4; the urine mask 6 comprises a urine inlet 7 and a urine outlet, the urine inlet 7 is attached to the urination port of the cow, and the urine outlet is connected to the urine collecting bag 4; the urine collecting bag 4 is tied to the waist and abdomen of the cow, and a switchable urine drainage outlet 8 is arranged below the urine collecting bag 4.

[0038] The cow urine collection device provided in the embodiment of the present invention is used to temporarily collect the cow's urine by tying a urine collection bag 4 to the cow's waist and abdomen according to the cow's body shape characteristics. The urine collection bag 4 replaces the urinary catheter, which can effectively prevent the urinary catheter from being easily folded and entangled during the cow's walking, lying, and standing up, and does not affect the cow's normal activities. In addition, the urine collection bag 4 has a certain storage space and does not need to be connected to the collection bucket, thereby eliminating the tethering of the cow with ropes, further reducing the constraints on the cow's activities.

[0039] In a specific embodiment, a flow meter 10 is further provided at the urinary catheter outlet 8, and urine is discharged through the flow meter 10. Opening the urinary catheter outlet 8 allows urine to flow out of the flow meter 10, which not only frees up the storage space in the urine collection bag 4, but also automatically measures the amount of urine discharged by the cow through the flow meter 10, thereby meeting the needs of collecting and measuring urine of the cow.

[0040] The existing method of collecting cow urine is basically to introduce urine into a urine collection bucket through a urinary catheter, and then weigh the urine in the urine collection bucket or measure the volume. This is not only time-consuming and laborious, but also has the problem of entanglement of the urine catheter and overturning of the urine bucket. If a flow meter 10 is installed at the urinary catheter outlet 8, automatic measurement of the urine volume can be achieved. Since the density of cow urine is basically between 1.023 and 1.026, the volume can also be more accurately converted into mass.

[0041] Normal adult dairy cows urinate about 30L per day, urinate about 8-10 times, and urinate 2-4L per time. The urine is clean and free of impurities, with a pH between 7.7-8.7, which is weakly alkaline. Therefore, the selected flowmeter 10 should meet the precise measurement of intermittent short fluids and have a certain resistance to alkali corrosion. The turbine flowmeter is generally composed of a turbine, a bearing, an amplifier, and a display instrument. When the fluid flows through the turbine flowmeter, the impeller in the flowmeter rotates with the help of the kinetic energy of the liquid. At this time, the impeller blades cause the magnetic resistance of the magnetic circuit in the device to change periodically, so that an electrical pulse signal proportional to the flow is induced at both ends of the detection coil, which is amplified by the amplifier in the detector and sent to the display instrument. The instantaneous flow rate and the cumulative flow rate can be calculated based on the number of pulses and the cumulative number of pulses per unit time. It has obvious advantages such as compact structure, high reliability, low lower limit flow rate, wide measurement range, low cost, and low energy consumption, and has a very wide range of applications. After comprehensively considering the performance of various types of sensors, urine characteristics and economy, the flow meter 10 in this embodiment can be selected to have a diameter of 4-6 mm and a flow range of 0.1-0.6 m 3 / h corrosion-resistant turbine flowmeter 10.

[0042] In a specific embodiment, a cross valve 9 is further provided between the urinary catheter outlet 8 and the flow meter 10, for opening or closing the urinary catheter outlet 8. When urine needs to be discharged, the urinary catheter outlet 8 is opened through the cross valve 9, and the urine volume is automatically measured by the flow meter 10; when urine needs to be collected for sampling and analysis, the urinary catheter outlet 8 is closed through the cross valve 9, so that the urine is stored in the urine collection bag 4.

[0043] In order to tie and fix the urine mask 6 and the urine collecting bag 4 to the body of the cow, in a specific embodiment, the device also includes a fixing unit, which includes a belt 1, an upper strap 2 and a lower strap 3. Existing devices often use ropes and rubber bands as binding tools. The fixing and disassembly process is cumbersome and time-consuming, and requires high operator skills; there are multiple rubber bands, and if one of them is too tight or too loose, it may cause the urine collecting device to be displaced. In addition, the rubber band has a large tension after binding, which tightens the cow's body and causes discomfort. The fixing unit provided in this embodiment uses the physiological protrusions on the cow's waist and udder, combined with the large friction of the cow's hair to provide a counterforce for the device to be fixed. It is simple to operate, which can not only effectively reduce the operator's experience requirements and labor intensity, but also reduce the cow's stress and discomfort. Specifically, the belt 1 covers the protruding waist bone in front of the cow's upper back udder, and the two ends of the belt 1 are connected to the urine collection bag 4; the belt 1 can provide a pulling force for the upper strap 2, the lower strap 3 and the urine collection bag 4 and keep itself immobile through friction with the fur and the blocking of the waist bone and udder. One end of the upper strap 2 is connected to the middle part of the belt 1, and the other end is connected to the urine cover 6. One end of the lower strap 3 is connected to the urine cover 6, and the other end is connected to the urine collection bag 4.

[0044] Furthermore, the traditional rope knotting connection method is too cumbersome and difficult to ensure firmness, and makes the existing collection device complicated to install. In this embodiment, the belt 1 and the upper strap 2, and the belt 1 and the urine collection bag 4 are connected by an elastic band equipped with Velcro or multiple rows of metal hooks 5, which not only reduces the difficulty of connection and installation, but also can use Velcro or multiple rows of metal hooks 5 in combination with elastic bands to achieve a comfortable fit when the device is used on cows of different sizes.

[0045] In addition, the connection end of the upper strap 2 and the urine mask 6 is provided with a first bifurcated structure, and the bifurcated end of the first bifurcated structure is connected to the upper part of the urine mask 6; the connection end of the lower strap 3 and the urine mask 6 is provided with a second bifurcated structure, and the bifurcated end of the second bifurcated structure is connected to the lower part of the urine mask 6. The upper strap 2 and the lower strap 3 are used to pull the urine mask 6 from the upper and lower ends to form a limit, so that the urine mask 6 is closely attached to the urination port of the cow, and the urine mask 6 is prevented from shifting up and down, so as to overcome the problem that the existing collection device is easy to fall off and leaks urine seriously.

[0046] In order to reduce the stress of the cows and ensure the fixing strength, the waist belt 1, the upper strap 2 and the lower strap 3 can be made of elastic bands that are less irritating to the cow's skin, soft and elastic. The elastic material of the elastic band can be made of polyethylene terephthalate / polypropylene terephthalate (PET / PTT) two-component composite fiber, which has the capillary phenomenon on the basis of meeting the requirements of breaking strength, load elongation and air permeability, and can quickly absorb and dry the moisture on the skin, so that the skin remains fresh and comfortable.

[0047] In a specific embodiment, the urine collecting bag 4 includes a left bag and a right bag. The left bag is attached to the waist and abdomen between the left lower abdomen and the left leg of the cow, and the front of the left bag is connected to the left end of the waist belt 1; the right bag is attached to the waist and abdomen between the right lower abdomen and the right leg of the cow, and the front of the right bag is connected to the right end of the waist belt 1. The urine collecting bag 4 is set as a left bag and a right bag, which not only fully utilizes the body characteristics of the cow, reduces the discomfort of the cow, and is conducive to maintaining the balance on both sides, but also is connected to the urine cover 6 respectively, has a certain auxiliary fixing effect, forms a left and right limit for the urine cover 6, and prevents the urine cover 6 from being displaced left and right, so as to further overcome the problem that the existing collection device is easy to fall off and leaks urine seriously.

[0048] Regarding the selection of materials for the urine collection bag 4, the following considerations can be made: ① good waterproof performance to store urine; ② a certain degree of softness to fit the cow's body; ③ a certain degree of elasticity to adapt to cows of different sizes and to assist in fixing; ④ good transparency to facilitate observation of the situation inside the urine collection bag 4; ⑤ a certain degree of wear resistance; ⑥ a certain degree of corrosion resistance. In summary, based on the survey of common related materials on the market, PEVA (polyethylene-vinyl acetate) plastic can be selected. PEVA is a mixture of PE and EVA. It has good softness and a little elasticity. The higher the proportion of PE, the more difficult it is to handle adhesion. It is generally used to produce membranes. The ratio of these two chemical substances can be adjusted to meet different application needs. The higher the content of vinyl acetate, the higher its transparency, softness and toughness will be. It is currently the main manufacturing material for outdoor sports water bags.

[0049] Furthermore, the bottom of the left bag and the bottom of the right bag can be connected, and the urinary catheterization outlet 8 is provided at the connecting part of the left bag and the right bag. The urinary catheterization outlet 8 is located at the front side of the udder of the cow, which is convenient for switching and urinary catheterization and urination operations. The urine collection bag 4 can be set to store a volume of 12L urine, which meets the urination volume of 4-6 times of the cow and realizes urine collection for about 10 hours. In this way, when the urinary catheterization outlet 8 is opened, the automatic measurement of the urination volume of the cow can be realized by the flowmeter 10. When the urinary catheterization outlet 8 is closed, the urine volume storage for about 10 hours can be realized for sample collection, and there is no need for personnel to be on duty for a long time, which effectively reduces the labor intensity of the test personnel.

[0050] In a specific embodiment, a semi-pear-shaped urine chamber is provided in the urine cover 6, the urine inlet 7 is provided at the large end of the urine chamber, and the urine outlet is provided at the small end of the urine chamber. The frame of the urine cover 6 can be a hard plastic structure, and a soft silicone is provided as the urine inlet 7. The frame of the urine cover 6 has a certain rigidity, which can prevent deformation caused by extrusion and leakage of urine; the soft silicone can directly contact the skin, is not easy to cause allergies, and does not adhere to the skin, and is soft and elastic. Therefore, a relatively hard medical plastic can be selected as a shaping frame, and the part of the urine inlet 7 that contacts the skin adopts a relatively soft medical silicone to ensure that it fits the cow's vulva completely. The urine inlet 7 is oval, covering the entire pubic mons. When the cow urinates, the urine impacts the inner arch and then flows back to the bottom of the urine cover 6, preventing urine from splashing, and having a certain buffering effect. After the urine is discharged from the urethral opening, it enters the urine chamber through the oval opening to complete the initial collection, and then is discharged to the urine collection bag 4 from the urine outlet at the bottom of the urine chamber. According to the measurement results of the body size of 10 adult dairy cows, the length of the vulva of adult dairy cows is generally 8-12 cm. Since urine is discharged from the lower part of the vulva, the oval urine inlet 7 of the urine mask 6 can be selected to be 12*8 cm to meet the normal use in most cases. When the urine collecting bag 4 is set as a left bag and a right bag, the urine outlet of the urine mask 6 can be set with two openings accordingly. Four fixing buckles can be set around the urine mask 6 to connect with the two forked ends of the first forked structure and the two forked ends of the second forked structure, so as to facilitate disassembly, cleaning and replacement.

[0051] In a specific embodiment, a plurality of ventilation holes are provided on the upper part of the urine mask 6. Studies have shown that the airtight use of the urine mask 6 may cause erosive damage to the cow's genitals, so the ventilation holes are designed on the upper part of the urine mask 6, which can not only ensure that urine does not flow out of the ventilation holes, balance the pressure inside and outside the urine mask 6 so that urine will not be retained in the urine mask 6, but also prevent bacteria from growing in the urine mask 6.

[0052] For a specific embodiment of the present invention, the operation can be performed according to the following steps:

[0053] S1. Use a yoke or rope to restrain the test cows.

[0054] S2. Wrap the belt 1 around the abdomen in front of the line connecting the cow's waist and udder, adjust the tightness of the belt 1 according to the cow's body shape and waist circumference, select a suitable hook ring position, hang the metal hook on the cow's back, and complete the fixing of the belt 1.

[0055] S3. Pull the urine mask 6 connected with the upper strap 2 and the lower strap 3 through the space between the cow's hind legs to the cow's tail, insert the lower strap 3 into the gap between the cow's hind legs and the udder, and then adjust the tightness of the lower strap 3 to make the urine mask 6 cover the vulva intactly, then pass the cow's tail through the reserved hole of the upper strap 2, select the hook ring at the appropriate position on the belt 1 to hang the metal hook, and complete the installation of the upper strap 2 and the lower strap 3.

[0056] S4, connect the urine collecting bags 4 on both sides to the urine outlet of the urine mask 6 to complete the installation.

[0057] S5. When only urine volume needs to be measured, the urinary catheter outlet 8 is opened, and urine is collected and discharged from the urinary catheter outlet 8. When urine sampling is required, the urinary catheter outlet 8 is closed, and urine is retained in the urine collection bag 4.

[0058] S6. After the test is completed, empty the urine in the urine collecting bag 4, remove the waist belt 1 and the upper and lower straps 2 and 3, remove the urine mask 6, clean the urine mask 6 and the urine collecting bag 4, and wait for the next use.

[0059] When collecting feces and urine of dairy cows, in order to avoid mixing feces and urine, the test cows must be restrained and raised separately. The existing mode is to use ropes for limiting, which results in too small a range of activities for the cattle and generates greater stress. By using the urine collection device for dairy cows provided by the embodiment of the present invention, it is possible to solve the greater stress caused to the cattle by tethering and limiting feeding of cattle and the high labor intensity caused by artificial water and material feeding, and achieve the purpose of long-term full collection of feces and urine of dairy cows. Specifically, when using the urine collection device for dairy cows provided by the embodiment of the present invention, flexible iron ropes can be used to divide the entire house into several small units, each of which includes a bed, a neck yoke, a feeding port, etc., so that the test cattle are given a larger range of activities while ensuring separate feeding, and can rest in the bed, feed in the feeding area, and defecate in the defecation area, thereby reducing the stress caused by the limitation as much as possible.

[0060] In addition, since most cowsheds currently adopt a single-house single-water trough design, water must be manually fetched regularly for feeding after limited feeding. In order to prevent the cows from kicking over the buckets, manual care is required during the feeding period, and the daily water intake of adult dairy cows can reach 40 kg. On the one hand, this will bring high labor intensity to the test personnel, and on the other hand, it cannot meet the cows' need for drinking water at any time. After adopting the cow urine collection device provided by the embodiment of the present invention, installing an independent automatic drinking water device in each small unit can better solve this problem.

[0061] If collection and testing are carried out under a slatted floor environment, the existing slatted floor will cause feces and urine to flow into the manure ditch at the same time due to its size design, which makes it impossible to collect the feces with a shovel. When using the cow urine collection device provided by the embodiment of the present invention, a double-layer PP non-woven filter cloth can be laid on the existing slatted floor, so that urine can flow into the manure ditch and feces can remain on the filter cloth, which is convenient for test personnel to collect.

[0062] It can be seen from the above embodiments that the urine collection device for cows provided by the present invention, according to the body characteristics of the cows, ties a urine collection bag 4 to the waist and abdomen of the cows for temporarily collecting the urine of the cows. Replacing the urinary catheter with the urine collection bag 4 can not only effectively prevent the urinary catheter from being easily folded and entangled when the cows walk, lie down, and stand up, and does not affect the normal activities of the cows, but also the urine collection bag 4 has a certain storage space and does not need to be connected to the collection bucket, thereby eliminating the tethering of cows restricted by ropes and reducing the constraints on the cows' range of activities. Furthermore, compared with the prior art, the urine collection device for cows provided by the above embodiments of the present invention has the following advantages:

[0063] 1. The device only needs to be disassembled and assembled twice by unhooking the metal hook, which requires low operator experience and is easy and quick to disassemble and assemble.

[0064] 2. The fixing module of the device is shaped like the "underpants" of a cow. The design of multiple elastic bands and multiple rows of metal hooks 5 (or Velcro) enables the device to be suitable for cows of different sizes.

[0065] 3. With the help of the body shape limiting effect of the waist bone and the udder, as well as the upper and lower limiting effect of the upper strap 2 and the lower strap 3 on the urine cover 6, and the left and right limiting effect of the urine collecting bags 4 on the left and right sides on the urine cover 6, the device will not easily shift or fall off when the cattle walk, stand up or lie down after installation.

[0066] 4. The hard plastic frame of the urine mask 6 can prevent deformation by squeezing, and the soft urine inlet 7 can ensure a close fit with the mons pubis, effectively achieving the separation of feces and urine without using a strong adhesive.

[0067] 5. The urinary catheter and the urine collecting bag 4 are integrated inside the device, which fundamentally solves the problem of urine overflow caused by folding and entanglement of the urinary catheter.

[0068] 6. When the urinary catheter outlet 8 is opened, the flow meter 10 can be used to automatically measure the amount of urine discharged by the cow. When the outlet is closed, the urine volume of about 10 hours can be stored for sample collection. There is no need for personnel to be on duty for a long time, which effectively reduces the labor intensity of the test personnel.

[0069] 7. The cattle were allowed to eat, drink and rest freely during the experiment to minimize their stress during the experiment.

[0070] 8. Even without supervision, effective feces and urine collection and full measurement can be achieved, which greatly reduces the labor intensity of test personnel.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
