Description

Technical Field

[0001] The present invention relates to the technical field of buffalo breeding, and in particular to a buffalo safety protection and delivery device. Background Art

[0002] In cattle farming, artificial assisted birthing is often used to improve the survival rate of newborn calves, prevent injuries to cows during birthing, and protect their reproductive function. Dystocia is common during birthing, necessitating manual or mechanical assistance to ensure the health of both the cow and calf. Dystocia can be caused by a variety of factors, such as an oversized calf, malpositioned fetus, or poor health of the cow. To effectively address dystocia, artificial assisted birthing has become a common practice. During the assisted birthing process, a breeder or veterinarian may manually assist the cow with the calf, using appropriate techniques and tools.

[0003] In the prior art, a Chinese patent document with publication number CN114732562A proposes a buffalo delivery device with a safety protection function. Due to the arrangement of the No. 4 slot and the limit block, the flat plate can only move vertically along the No. 4 slot. By pulling the circular ring, due to the connection between the circular ring, the metal rope and the flat plate, the flat plate can be pulled vertically downward by pulling the metal rope, and the two No. 2 springs are compressed. Due to the fixed connection between the flat plate and the lock pin, the lock pin can be driven to move downward. When the lock pin moves out of the No. 3 slot, the mounting plate fixedly connected to the left side of the camera is inserted into the No. 3 slot, and then the circular ring is released. Due to the elastic restoring force of the No. 2 spring, the flat plate is pushed vertically upward, and then the lock pin is driven to move upward and inserted into the lock slot. The position of the mounting plate is locked, and the camera is fixed. However, consistent with the traditional method, when the buffalo is giving birth and the calf's angle is misaligned, the calf's legs are first squeezed out by the buffalo's contractions. At this time, the buffalo is in a state of dystocia. Traditional obstetric devices usually use ropes to tie the calf's legs, which do not have good adjustment flexibility and cannot adapt to the legs of calves of different sizes. They are also prone to damage to the calf's legs. In addition, the force mode during pulling is relatively single, and it is easy to loosen or dislocate during operation, resulting in insufficient obstetric effect. Therefore, the present application discloses a buffalo safety protection obstetric device to meet the requirements of good adjustment flexibility when assisting buffaloes in giving birth. Summary of the Invention

[0014] Preferably, the handle layer is hollowed out, and one side of the handle is provided with a plurality of arc grooves that fit the hand.

[0015] Beneficial effects of the present invention:

[0016] 1. This buffalo safety protection and midwifery device is provided with a sleeve assembly and a tension assembly, and is connected to the opening and closing position of the sleeve ring through a threaded column, so that the user can easily adjust the opening and closing degree of the sleeve ring according to needs to adapt to calves of different sizes. In actual midwifery operations, it can better adapt to different situations, thereby improving the versatility and flexibility of midwifery equipment. When performing midwifery operations on calves, the user holds the rotating handle to drive the rotating wheel to rotate, and the rotating wheel drives the rotating rod to rotate. In the process of rotating the rotating rod, the winding segments on both sides of the rotating rod will be driven to rotate synchronously. This in turn drives the two steel ropes to be retracted and extended synchronously. This synchronous movement can effectively deal with the delivery situation of calves in a dystocia state and provide powerful midwifery guidance. Baffles are provided on both sides of the two winding sections to prevent the steel ropes from being wound out of their position. Therefore, when the two steel ropes are retracted and extended, the socket assembly is stretched to assist in inducing labor in the calf. Since the two steel ropes are arranged in a cross pattern, force can be applied evenly, avoiding excessive pressure in a single direction, improving the safety of midwifery, making midwifery operations safer and more efficient, and more in line with the actual needs in different situations.

[0017] 2. This buffalo safety protection and obstetric device is made of silicone material by setting a limit block on the socket assembly and the inner wall of the socket ring. The inner wall of the silicone socket ring helps to provide a certain buffer and protection effect to avoid unnecessary damage to the calf's legs. The limit block is rotatably installed on the other side of the opening and closing mouth of the socket ring. The limit block wraps one side of the socket ring in a semicircular shape. The cam structure of the limit block does help to achieve smooth limiting during the opening and closing process. When locking, the triangular side of the limit block can be pushed to drive one side of the cam structure to rotate, thereby locking the opening and closing mouth more firmly to prevent accidental falling off and opening and closing, improving the locking stability and reliability, and ensuring that the limit block can effectively remain in the required position when using the obstetric device, avoiding unnecessary movement, and thus having a protective effect on the calf's legs while having locking fixation.

[0018] 3. This buffalo safety protection and midwifery device is equipped with auxiliary components. When cleaning the mouth and nose of a calf after delivery, a longer pipe is connected to the trachea above the negative pressure airbag. At this time, the second limit plate and the rotating plate are engaged with one hand to drive the first limit plate to move to cooperate with one side of the clamping frame to squeeze the negative pressure airbag. Because the clamping frame and the first limit plate are both set in a "V" shape, it is easier to squeeze the wrapped negative pressure airbag, which ensures that the pressure applied to the mouth and nose of the calf when cleaning the mouth and nose is moderate, avoiding unnecessary discomfort. At this time, press it still, then align the pipe with the calf's mouth and nose, release the engagement state of the second limit plate and the rotating plate, and repeat this operation to absorb the liquid in the calf's mouth and nose.

[0032] like Figures 1 to 8As shown, the buffalo safety protection and midwifery device comprises: a clamp body 1, one end of the clamp body 1 is fixedly connected to a top rod 2 on both sides, the other end of the clamp body 1 is rotatably mounted with a connecting plate 3, the connection between the clamp body 1 and the connecting plate 3 is vertically provided with a rotating shaft 4, the other end of the connecting plate 3 is fixedly connected to a handle 6, and an extension plate 5 is provided on the side of the connecting plate 3 close to the handle 6; a tension component, the bottom end of the tension component is provided with a mounting plate 7 fixedly connected to the middle top of the connecting plate 3, the tension component comprises a rotating rod 9 for winding, and two steel wire ropes 11 for pulling, the two steel wire ropes 11 are respectively wound on both sides of the rotating rod 9, and one side of the two steel wire ropes 11 is provided with an external thread section; a socket component 15, the socket component 1 5 includes a sleeve ring 16 and a threaded column 17 for adjusting the opening size of the sleeve ring 16. A connecting hole 21 is opened on one side of the sleeve ring 16. The connecting hole 21 is an internal thread groove. The sleeve assembly 15 is threadedly connected to one side of the wire rope 11 through the connecting hole 21; an auxiliary assembly, a clamping frame 22 is set on the top of the auxiliary assembly to be clamped under the extension plate 5, and the auxiliary assembly includes a first limiting plate 23 and a second limiting plate 24 rotatably mounted on both sides of the clamping frame 22, and a negative pressure airbag 25 for absorbing calf nasal mucus. The negative pressure airbag 25 is set between the clamping frame 22 and the first limiting plate 23. Among them, the handle 6 is hollowed out, and a plurality of arc grooves are opened on one side of the handle 6 to fit the hand;

[0033] When the buffalo is giving birth, the calf's angle is offset, and the calf's legs are squeezed out by the buffalo's uterine contractions first. At this time, the buffalo is in a state of dystocia. Then, the grip handle 6 is used to drive the clamp body 1 to lift up, and the top rod 2 is pressed against the buffalo's buttocks. Then, the two sleeve components 15 are pulled, and the sleeve ring 16 is put on the calf's legs that are squeezed out first. The sleeve component 15 allows the threaded column 17 to adjust the opening size of the sleeve ring 16 to accommodate calves of different sizes. Then, by adjusting the rotating rod 9 on the tension component, the two steel ropes 11 above are driven to wind, and then the sleeve component 15 is pulled. The calf can be moved to assist the buffalo cow in giving birth. During the giving birth process, the connecting plate 3 is connected to the clamp body 1 through the rotating shaft 4. Then, during the giving birth, the connecting plate 3 can be rotated to adjust the angle according to the giving birth status of the cow, making it more convenient and improving the giving birth efficiency. After the calf is born, the condition of the cow after dystocia and the calf just born from dystocia is inevitably poor. At this time, the negative pressure air bag 25 on the squeezing auxiliary component is used to absorb the mucus on the calf's mouth and nose, so that the calf will not suffocate after giving birth, providing timely protection and care for the calf that has just been born.

[0034] like Figure 3 、 Figure 6As shown, bearing seats 8 are fixedly installed on both sides of the mounting plate 7, and bearings are provided inside the two bearing seats 8. A rotating rod 9 passes through the bearings inside the two bearing seats 8. A connecting rod is extended at one end of the rotating rod 9, and a rotating wheel 13 is fixedly installed at one end of the connecting rod. A rotating handle 14 is rotatably installed on one side of the rotating wheel 13. Two winding segments 10 are respectively provided on both sides of the rotating rod 9, and baffles are respectively provided on both sides of the two winding segments 10. One side of the two steel ropes 11 is respectively wound around the outer surface of the two winding segments 10. A splitter 12 is also provided on one side of the top of the connecting plate 3. The two steel ropes 11 respectively pass through the splitter 12, and the two steel ropes 11 are cross-arranged, and the two steel ropes 11 are arranged one above and one below;

[0035] When performing an assisted delivery operation on a calf, the rotating handle 14 is held to drive the rotating wheel 13 to rotate, and the rotating wheel 13 drives the rotating rod 9 to rotate. During the rotation process, the rotating rod 9 will drive the winding segments 10 on both sides of the rotating rod 9 to rotate synchronously, thereby driving the two steel ropes 11 to be retracted and released synchronously. This synchronous movement can effectively cope with the delivery situation of the calf in a dystocia state and provide powerful assisted delivery guidance. Baffles are provided on both sides of the two winding segments 10 to prevent the steel ropes 11 from being wound out of their position. Therefore, when the two steel ropes 11 are retracted and released, the socket assembly 15 is stretched to assist in inducing delivery of the calf. Since the two steel ropes 11 are cross-arranged, force can be applied evenly, avoiding excessive pressure in a single direction, improving the safety of assisted delivery, making assisted delivery operations safer and more efficient, and more in line with actual needs in different situations.

[0036] like Figure 7 As shown, the sleeve ring 16 is rotatably opened and closed, and the threaded column 17 is connected to the opening and closing position of the sleeve ring 16 by a thread. One end of the threaded column 17 is fixedly connected to a rotating ring 18, and the outer surface of the rotating ring 18 is provided with a plurality of teeth that increase friction. A limit block 19 is rotatably installed on the other side of the opening and closing mouth of the sleeve ring 16. The limit block 19 is semicircular and wraps one side of the sleeve ring 16. The side of the limit block 19 close to the opening and closing mouth is provided with a cam structure, and the other side of the limit block 19 is triangular, and a plurality of ridges 20 are provided on both sides. The inner wall of the sleeve ring 16 is provided with a silicone material.

[0037] The threaded column 17 is connected to the opening and closing position of the sleeve ring 16 by a thread, so that the user can easily adjust the opening and closing degree of the sleeve ring 16 as needed to adapt to calves of different sizes. It can better adapt to different situations in actual midwifery operations, thereby improving the versatility and flexibility of midwifery equipment. One end of the threaded column 17 is fixedly connected to a rotating ring 18, and the outer surface of the rotating ring 18 is provided with teeth that increase friction, making the threaded column 17 easier to operate and increasing the firmness of the connection. At the same time, the inner wall of the sleeve ring 16 made of silicone material helps to provide a certain buffer and protection to avoid damage to the calf's legs. To prevent unnecessary injuries, a limit block 19 is rotatably installed on the other side of the opening and closing mouth of the sleeve ring 16. The limit block 19 is wrapped in a semicircular arc shape on one side of the sleeve ring 16. The cam structure of the limit block 19 does help to smoothly achieve the limit during the opening and closing process. When locking, the triangular side of the limit block 19 can be pushed to drive one side of the cam structure to rotate, thereby more firmly locking the opening and closing mouth to prevent accidental falling off and opening and closing, thereby improving the stability and reliability of the locking, and ensuring that the limit block 19 can effectively remain in the desired position when the midwifery device is used, avoiding unnecessary movement.

[0038] like Figure 2 、 Figure 8 As shown, the side of the clamping frame 22 close to the negative pressure airbag 25 is set in a "V" shape, and the first limiting plate 23 is also set in a "V" shape as a whole. A rotating plate 27 is rotatably installed on the other end of the first limiting plate 23. A spring 28 is provided between the second limiting plate 24 and the rotating plate 27. The negative pressure airbag 25 is set in an oval shape, and the contact surface between the negative pressure airbag 25 and the clamping frame 22 and the first limiting plate 23 is provided with Velcro. An air pipe 26 is also provided above the negative pressure airbag 25, and the air pipe 26 can be externally connected to a pipe of the same specification;

[0039] When cleaning the mouth and nose of a calf after birth, a longer pipe is connected to the trachea 26 above the negative pressure airbag 25. At this time, the second limit plate 24 and the rotating plate 27 are engaged with one hand to drive the first limit plate 23 to move to cooperate with one side of the clamping frame 22 to squeeze the negative pressure airbag 25. Because the clamping frame 22 and the first limit plate 23 are both set in a "V" shape, it is easier to squeeze the wrapped negative pressure airbag 25, which ensures that the pressure applied to the mouth and nose of the calf when cleaning the mouth and nose is appropriate to avoid unnecessary discomfort. At this time, press it still, then align the pipe with the calf's mouth and nose, release the engagement of the second limit plate 24 and the rotating plate 27, and repeat this operation to absorb the liquid in the calf's mouth and nose.
