Description

Technical Field

[0001] The invention relates to the technical field of dairy cow breeding, and in particular to a low blood calcium early warning and automatic replenishment device for dairy cows. Background Art

[0002] Hypocalcemia in dairy cows, especially in the postpartum stage, is an extremely serious metabolic disorder that mainly attacks dairy cows in the early stages of delivery, especially in high-yielding dairy cows, those with good nutritional status, and those who are older and have had more parities. This disease not only seriously threatens the health of dairy cows, but can also cause paralysis and loss of the ability to stand, which in turn directly impacts the economic benefits of the farm.

[0003] During the periparturient period, the blood calcium concentration of dairy cows begins to gradually decline one week before calving, and reaches the bottom when delivery is approaching. Although the blood calcium level will rise after delivery, the stress response caused by delivery and the surge in calcium demand often cause many dairy cows to fall into a state of insufficient blood calcium after delivery, which in turn induces clinical hypocalcemia. Typical symptoms of this disease include stiff hind limbs, inability to get up, stiff head and neck tilted toward the chest, body temperature suddenly dropping below 38°C, and rumen bloating. Although subclinical hypocalcemia has no obvious symptoms on the surface, it will quietly weaken the cow's feeding ability and milk production, thereby damaging its overall health and production efficiency.

[0004] In view of the above severe situation, the detection and early warning of blood calcium in dairy cows are particularly important during the peripartum period. However, current technology mainly relies on blood calcium content measuring instruments. Such equipment requires operators to follow cumbersome steps, including regular blood collection, blood preservation, equipment calibration and operation, which undoubtedly increases the burden on personnel and causes unnecessary consumption of human resources. What is more difficult is that these steps often require operators to have certain professional knowledge, which undoubtedly raises the threshold for employment in the dairy farming industry and poses a potential obstacle to the sustainable development of the industry.

[0005] In addition, the existing blood calcium content measuring instruments often fail to replenish calcium for dairy cows in a timely and effective manner after detecting symptoms of hypocalcemia in dairy cows, which may cause the cows' condition to deteriorate sharply in the short interval between detection and treatment. Therefore, how to optimize the detection and early warning mechanism of dairy cow blood calcium and ensure that measures can be taken quickly to intervene after the symptoms of hypocalcemia are found has become a key issue that needs to be solved urgently.

[0019] 1. In this scheme, multiple blood collections from the same cow are achieved through the design of several blood collection needles.

At the same time, the supply cavity and the test cavity are used to enable the blood collection needle to be connected to different chambers according to different needs, so as to achieve the purpose of blood collection or injection of calcium injection, without the need to arrange additional injection needles, reducing the use cost. At the same time, since the same type of blood collection needle is used for blood collection and injection, there is no need to make two molds during the production process, which is conducive to reducing the production cost.

[0020] 2. In this solution, the drive block is designed to give an initial velocity using the first spring and the first electromagnet, and then the drive block is accelerated by the second electromagnet, so that the drive block has a certain initial velocity when leaving the drive slot, thereby achieving impact on the test cavity and prompting the blood collection needle to pierce the cow's skin. During the movement of the drive block in the injection, bubbles are generated inside the injection, which helps to discharge the gas inside the injection and reduce the air content in the injection, thereby improving the safety of the injection process. At the same time, it also allows operators to not pay attention to the problem of air when filling the injection into the equipment, thereby reducing the difficulty of using the equipment and improving the market acceptance of this solution.

The top wall of the moving block 251 is welded and fixed with a first The second spring 254, the other end of the second spring 254 is welded and fixed to the inner top wall of the blood collection needle 21, and in the present embodiment, the second spring 254 is sleeved on the button 253, the elastic modulus of the replenishing chamber 13 and the test chamber 12 are both smaller than the second spring 254, a curved hole 252 is opened in the moving block 251, the replenishing chamber 13 can be connected with the blood collection needle 21 through the curved hole 252, the replenishing chamber 13 and the test chamber 12 are both made of elastic material, a plurality of driving components 24 are arranged on the side wall of the replenishing chamber 13 away from the blood collection needle 21, and one end of the driving component 24 away from the side wall of the replenishing chamber 13 can be detachably connected with the driving block 22, and the driving component 24 is used to drive the blood collection needle 21 and the valve 21 through the driving block 22 5 work, the driving assembly 24 includes a plurality of driving grooves opened in the side wall of the supply chamber 13 away from the blood collection needle 21, the bottom wall of the driving groove is fixed with a first spring 242 by welding, the bottom wall of the driving groove is fixedly connected with a first electromagnet 241 by bolts, the driving block 22 is arranged at one end of the first spring 242 away from the bottom wall of the driving groove, the side wall of the driving groove is arranged with a permanent magnet 244 and a plurality of second electromagnets 243, the driving block 22 is made of magnetic material, the second electromagnet 243 is used to limit the position of the driving block 22 and adjust the speed of the driving block 22, the housing 1 is also provided with a communication module, and a sealing strip 11 of elastic material is bonded and fixed to the side wall of the housing 1 close to the blood collection needle 21,

[0037] It also includes a control system, which includes a first controller. The first electromagnet 241, the second electromagnet 243 and the communication module are all electrically connected to the first controller. The first controller is used to receive timing information input by a user and control the first electromagnet 241 to work according to the timing information. The first controller is also used to receive calcium content information and control the second electromagnet 243 and the communication module to work according to the calcium content information.

[0038] The specific implementation process is as follows: before using the device, negative pressure is created in the test chamber 12, and a suitable cleaning fluid that can be used for the biosensor is placed in the cleaning chamber 14. When installing the device, first identify the cows that are at risk of hypocalcemia, such as dividing the cows into different areas, collecting urine from cows in each area for testing, and confirming the cows that may be at risk of hypocalcemia, or dividing the cows into peripartum cows according to the time of their birth, and selecting the position of these cows that is easy for subcutaneous injection and subcutaneous blood drawing, removing the hair on the upper part, and disinfecting the position, and then placing the sealing strip 11 of the device there, and exhausting the air between the bottom wall of the device and the cow's skin. The design of the sealing strip 11, while using negative pressure to reduce the risk of the device falling off the cow's skin, also constructs a sterile area on the cow's skin, which can reduce the probability of bacterial infection on the cow's skin at this position during subsequent use, and then tape or the like can be used to fix the device to the cow.

[0039] Then the device is started, and the user designs a reasonable blood calcium content detection interval according to the cow's condition, that is, timing information, and inputs it into the first controller.

[0040] During use, when the time point set by the timing information is reached, the first controller controls any one of the first electromagnets 241 to work, and starts the second electromagnets 243 corresponding to the first electromagnet 241 to work. The magnetic force generated by the first electromagnet 241 drives the driving block 22 to move inside the driving slot, thereby disengaging from the permanent magnet 244 and compressing the first spring 242 at the same time. Then the first controller cuts off the current of the first electromagnet 241. Under the action of the elastic potential energy of the first spring 242, the driving slot moves in the direction of disengaging from the driving slot. During the movement, affected by the magnetic field of the second electromagnet 243, the speed of the driving block 22 gradually increases. The force of the driving block 22 gradually increases, and then the driving block 22 enters the replenishing chamber 13 and hits the bottom wall of the replenishing chamber 13 and the top wall of the blood collection needle 21. Since the second spring 254 has a large elastic modulus, the second spring 254 does not deform or deforms slightly at this time, and cannot cause the replenishing chamber 13 to communicate with the inside of the blood collection needle 21, causing the bottom wall of the replenishing chamber 13 and the test chamber 12 to deform, thereby pushing the blood collection needle 21 corresponding to this part to move in the direction of the cow's skin. At the same time, the deformation of the test chamber 12 causes a gap to appear between the test chamber 12 near the cow's skin and the outer wall of the blood collection needle 21, so that the blood collection needle 21 can The kinetic energy is lost in the process of transferring between the supply chamber 13 and the test chamber 12, so that the deformation of the test chamber 12 is smaller than the side wall of the supply chamber 13. Therefore, the supply chamber 13 compresses the space in the test chamber 12 while pushing the test chamber 12 to deform, so that part of the fluid in the test chamber 12 enters the recovery chamber 17. Under the action of the cow's own blood and the negative pressure in the test chamber 12, the cow's blood enters the test chamber 12 through the blood collection needle 21 (due to the restriction of the first one-way valve 26, the blood can only enter the test chamber 12 from the blood collection needle 21, but cannot enter the test chamber 12 from the test chamber 12). 2 enters the blood collection needle 21, effectively avoiding the backflow of the collected blood and causing adverse effects on the cow), moves in the test chamber 12 under the action of the liquid surface tension, and is detected by the biosensor therein to obtain calcium information. Then the test chamber 12 and the supply chamber 13 are reset, driving the blood collection needle 21 to reset. At the same time, as the test chamber 12 is reset, the volume of the space in the test chamber 12 increases and the air pressure decreases. Under the action of the air pressure, the cleaning liquid in the cleaning chamber 14 is guided into the test chamber 12 to clean the biosensor and the test chamber 12, thereby reducing the influence of the blood that entered the test chamber 12 in the early stage on the accuracy of subsequent blood testing.

[0041] If the calcium content information is greater than or equal to the preset value at this time, the blood calcium of the cow is at a normal level and no human intervention is required. At this time, when the set time point is reached next time, the first controller controls any one of the first electromagnets 241 driven last time to work again, so that it drives the driving block 22 to separate from the permanent magnet 244 and compress the spring, and accelerates to hit the bottom wall of the supply chamber 13 again under the action of the second electromagnet 243, so that the supply chamber 13 and another area of ​​the test chamber 12 are deformed, and the blood collection needle 21 in the corresponding area is pushed to collect blood from the cow. In the process of deformation of the test chamber 12, the internal space of the test chamber 12 is reduced again, which helps the cleaning liquid to enter the recovery chamber 17, and at the same time discharges a small amount of gas into the recovery chamber 17, so that the test chamber 12 is restored to the initial pressure to a certain extent.

[0042] If the calcium content is less than the preset value at this time, the cow is very likely to have hypocalcemia. The first controller determines that the cow is clinically hypocalcemic or subclinically hypocalcemic according to the range of the calcium content information, and according to the symptoms of the cow, the first controller operates different numbers of first electromagnets 241 to release the drive blocks 22 at the corresponding positions, and controls all the second electromagnets 243 to operate, and adjusts the current of the second electromagnets 243, etc., to increase the initial velocity of the drive block 22 when it leaves the drive slot, so that the drive block 22 When the side wall of the driving chamber and the top wall of the blood collection needle 21 are driven, the kinetic energy transmitted to the button 253 on the top wall of the blood collection needle 21 increases, thereby compressing the second spring 254. The moving block 251 moves toward the direction of the test chamber 12, so that the bent tube moves to a suitable position to connect the supply chamber 13 with the blood collection needle 21, and at the same time, the blood collection needle 21 enters the subcutaneous part of the cow. At this time, the injection in the driving chamber is injected into the subcutaneous part of the cow through the blood collection needle 21. Subsequently, as the test chamber 12 and the driving chamber are reset, the blood collection needle 21 is detached from the subcutaneous part of the cow, completing a calcium supplement. During the calcium supplementation process, the elastic modulus of the supply cavity 13 and the test cavity 12 is fixed, so that the time for the blood collection needle 21 to inject the calcium supplement injection into the cow is relatively fixed. At this time, the amount of calcium supplemented this time is selected according to the hypocalcemia condition of the cow, and the number of the first electromagnets 241 that should be started this time is calculated according to the diameter of the blood collection needle 21 and other elements, so that this solution can supplement different amounts of calcium according to the specific needs of the cow, effectively improving the flexibility of the device. After the cow has hypocalcemia, the first controller also controls the communication module to output the corresponding calcium content information of the cow to the user, as well as the approximate amount of the injection injected at this time.

[0043] The design of the driving block 22 in this solution uses the permanent magnet 244, the first spring 242 and the second electromagnet 243 to increase the initial velocity of the driving block 22 when it leaves the driving slot during the process of the driving assembly 24 releasing the driving block 22, so that the driving block 22 can enter the injection at a higher speed, so that bubbles are generated in the injection and float around the driving block 22, thereby reducing the contact area between the driving block 22 and the injection, thereby reducing the kinetic energy loss of the driving block 22 in the process of passing through the injection. At the same time, due to buoyancy and other reasons, the gas in the injection escapes from the injection, thereby reducing the bubbles in the injection finally injected into the cow's body, which helps to improve the safety of the equipment. At the same time, the design of the driving block 22 is that after it drives the blood collection needle 21 at its corresponding position to draw blood, it enters the supply chamber 13 and follows the movement of the cow to move slowly in the supply chamber 13, thereby achieving stirring of the injection and preventing certain static injections that are easy to precipitate from precipitating due to the static movement of the cow. Moreover, since the driving block 22 cannot enter the corresponding driving chamber again, it is impossible to drive the blood collection needle 21 at the corresponding position to repeatedly penetrate the cow's subcutaneous tissue and repeatedly stimulate the same position, thereby avoiding problems such as skin inflammation and infection in the cow.

[0044] Embodiment 2:

[0045] The difference from Example 1 is that a closing block 23 is provided between the first spring 242 and the driving block 22, the closing block 23 is slidably matched with the inner wall of the driving groove, and the closing block 23 is welded and fixed to the end of the adjacent first spring 242 away from the inner wall of the driving groove.

[0046] The specific implementation process is as follows: During the use of the device, as the driving block 22 is released from the driving groove, the closing block 23 moves in the direction away from the first electromagnet 241 under the action of the first spring 242, blocking the driving groove, preventing the injection from entering the driving groove and causing corrosion to the first spring 242, etc., while also reducing the probability of the gas in the driving groove entering the injection, thereby reducing the probability of this part of the gas causing an increase in the gas in the injection.

[0047] Embodiment 3:

[0048] The difference from Example 2 is that it also includes a camera and a second controller, the camera is used to collect image information of cows, in this embodiment, the camera is arranged at a suitable position on the top of the cowshed, so that the camera can collect images of all cows to be monitored, the camera is electrically connected to the second controller, the first controller is signal-connected to the second controller, the second controller obtains the spotted information of the cow according to the image information, marks the cow according to the spotted information, and obtains the rumination status of the cow according to the image information, and compares the real-time rumination status of the same cow with the initial rumination status. When the two are the same, the cow is in a normal state. When the two are different, the second controller outputs an abnormal signal to the first controller, and the first controller controls the first electromagnet 241 and the communication module to work according to the abnormal signal.

[0049] The specific implementation process is as follows: when using this device, a camera is used to continuously collect image information of the cow. The second controller obtains the spotted information of the cow through image recognition technology. Since the spotted information of the cow is mostly unique, the spotted information can be used to locate the cow to a certain extent. By continuously collecting image information of the cow, the time point, duration, number of times and frequency of the cow's rumination per unit time are obtained. When the rumination status of the cow is first obtained, the information is used as the initial rumination status and compared with it in subsequent rumination status. When the rumination status collected in real time is not tired from the initial rumination status, the cow may have abnormal rumination, and the cow may have obvious symptoms of hypocalcemia. At this time, the second controller wants to output an abnormal signal to the first controller. The first controller controls the first electromagnet 241 of the equipment on the corresponding cow to work according to the abnormal information, conducts a blood test, and alarms the user by controlling the communication module.

[0050] The design of this solution uses a camera, etc., so that in actual operation, the user can appropriately expand the range of cows wearing this device, and focus on collecting images of the cows in the expanded range. Only when these cows show certain dominant characteristics of hypocalcemia, they are tested for hypocalcemia and automatically replenished. If these cows are always in a normal state, the device will not be started to reduce the consumption of blood collection needles 21, etc. This solution uses image information to further screen cows that use this device for blood calcium testing, which, to a certain extent, expands the range of blood calcium testing while reducing the ineffective consumption of the equipment, thereby reducing the cost of using the equipment.

[0051] Embodiment 4:

[0052] The difference from Example 3 is that the supply chamber 13 is also connected to the storage chamber 16, and a water-gas separation valve is provided at the connection point. A movable chamber 15 is opened in the side wall of the supply chamber 13 away from the blood collection needle 21. The movable chamber 15 is connected to a water pump (not shown in the figure), and the water pump is connected to the storage chamber 16. A first solenoid valve is provided at the connection points between the movable chamber 15 and the storage chamber 16 and the water pump. The water pump and the first solenoid valve are electrically connected to the first controller. The water pump is also connected to the recovery chamber 17, and a second solenoid valve is provided at the connection point between the recovery chamber 17 and the water pump. The first controller controls the operation of the water pump, the first solenoid valve and the second solenoid valve according to the timing information and the calcium content information.

[0053] The specific implementation process is as follows: During the use of this device, when bubbles escape from the injection, the gas enters the storage chamber 16 through the water-gas separation valve, and the injection cannot pass through the water-gas separation valve and is retained in the supply chamber 13. When the first controller controls the first electromagnet 241 to work according to the timing information and the calcium content information, the controller water pump and the corresponding first solenoid valve work to reduce the air pressure inside the storage chamber 16. As the drive block 22 moves, part of the gas inside the injection escapes. At this time, the water pump can use the air pressure to collect a large amount of this gas into the storage chamber 16 to prevent the gas from entering the injection again during the subsequent movement of the device. At the same time, the controller controls the second solenoid valve to work, so that there is a negative pressure in the recovery chamber 17, which prompts the cleaning fluid in the test chamber 12 to enter the recovery chamber 17, reduce the residual cleaning fluid in the test chamber 12, and improve the stability and accuracy of subsequent blood calcium detection.

[0054] When the first controller determines that the cow has hypocalcemia based on the calcium content information, it controls the first electromagnet 241 and the second electromagnet 243 to work. The controller controls the water pump and the corresponding first solenoid valve to work, and pumps the fluid in the recovery chamber 17 and the storage chamber 16 into the movable chamber 15, thereby driving the side wall of the replenishing chamber 13 away from the blood collection needle 21 to deform, compressing the space inside the replenishing chamber 13, and prompting the injection to enter the cow's subcutaneous tissue through the blood collection needle 21. This allows the device to maintain a certain calcium replenishment capacity when facing some cows with higher blood pressure. At the same time, the gas and cleaning fluid are used to drive the movable chamber 15 to deform without the entry of external fluid. Therefore, the weight of the equipment will not increase during use, and it is not easy for the equipment to fall off the cow's back due to the increase in weight.

[0055] Embodiment 5:

[0056] The difference from the fourth embodiment is that the first springs 242 are all made of metal, a battery is also arranged in the housing 1, a switch is connected to the battery, and the first springs 242 are all electrically connected to the switch.

[0057] The specific implementation process is as follows: after the device is used once, the operator can remove the used blood collection needle 21, clean and dry the remaining parts of the device, and replace the blood collection needle 21. After the blood collection needle 21 is replaced, the operator can invert the device and use the switch to connect the circuit between the first spring 242 and the battery. As the first spring 242 is energized, an electromagnetic field is generated in each coil of the first spring 242, and adjacent electromagnetic fields attract each other, so that the first spring 242 is tightened, driving the closing block 23 to move away from the blood collection needle 21, so that the permanent magnet 244 in the driving slot is exposed in the supply chamber 13. At this time, the operator can easily place the driving block 22 at a suitable position in the driving slot, complete the assembly, and then perform the next cow blood calcium test.

[0058] Compared with the prior art, the present solution utilizes electromagnetic induction to contract the first spring 242, thereby assisting the operator in returning the drive block 22 to its original position, thereby simplifying the operator's operating steps. At the same time, since the operator does not need to press the first spring 242, the operator is less likely to develop occupational diseases such as tenosynovitis due to repeated pressing actions, thereby reducing the health problems that the equipment may bring to the operator, and is conducive to improving the operator's satisfaction and work efficiency.

[0059] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
