Description

Technical Field

[0001] This utility model relates to the field of restraint technology, and in particular to a restraint for intratracheal inoculation of animals. Background Technology

[0002] Currently, when administering vaccines, drugs, or pathogens via tracheal inoculation or infection to animals such as pigs, the animals must first be restrained. For example, by maintaining a specific body position (limbs facing upwards, head and tail at a 45-50 degree angle), the inoculum can be quickly and accurately delivered into the lower respiratory tract via the trachea after a certain period of time, preventing reflux and subsequent inoculation failure. However, previously, during injection challenge, several staff members typically needed to hold the animal's limbs and hold it for several minutes, requiring a large number of personnel and consuming considerable physical exertion. Furthermore, because the trachea of ​​animals such as pigs is free and mobile, the struggle of manually restraining the pig makes it difficult to accurately fix the trachea for tracheal injection, leading to operation failure due to animal struggle and a low success rate.

[0003] Therefore, it is necessary to provide a restraint for intratracheal inoculation of animals to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this invention is to provide a restraint frame for intratracheal inoculation of animals, which aims to improve the low success rate of artificial animal restraint operations. It can firmly fix animals such as pigs and reduce physical exertion.

[0005] To achieve the above objectives, this utility model provides a restraint frame for intratracheal inoculation of animals, comprising:

[0006] A base frame, on which a plurality of spaced sliding rods are provided;

[0007] A fixed side plate is provided on one side of the base frame;

[0008] A lateral sliding side plate, which is slidably connected to the sliding rod, is used together with the fixed side plate to fix the animal.

[0009] A movable plate fixing rod, one end of which is fixed to the transverse moving side plate, and is provided with a plurality of spaced-apart pin holes;

[0010] A positioning pin is used to insert into one of the pin holes and cooperate with the base frame to fix the position of the transverse side plate;

[0011] Multiple restraint straps are used to restrain predetermined parts of the animal.

[0012] In a preferred embodiment, the base frame includes a pair of supports, each of the supports including a horizontal bar, a first support bar, and a second support bar; the horizontal bar, the first support bar, and the second support bar together form a triangle so that the first support bar is inclined, and the two ends of the sliding bar are respectively fixed to the two first support bars.

[0013] In a preferred embodiment, the second support rod is arranged perpendicular to the horizontal rod.

[0014] In a preferred embodiment, the fixed side plate includes a fixed plate and a first baffle perpendicularly disposed on the fixed plate, the fixed plate being fixed to a plurality of sliding rods; the transverse side plate includes a sliding plate and a second baffle perpendicularly disposed on the sliding plate, the sliding plate having at least one fixed sleeve on the side away from the second baffle, the fixed sleeve being sleeved on a predetermined sliding rod, so that the second baffle can move closer to or away from the first baffle along the length direction of the sliding rod.

[0015] In a preferred embodiment, one end of the restraint strap is fixed to the side of the first baffle away from the second baffle, the side of the second baffle away from the first baffle is provided with a fastening member, and the restraint strap is provided with a plurality of fastening holes; the fastening holes are used to cooperate with the fastening member to fasten the restraint strap.

[0016] In a preferred embodiment, both the side of the first baffle away from the sliding rod and the side of the second baffle away from the sliding rod are provided with clearance grooves corresponding to the restraint straps, the clearance grooves being used for the corresponding restraint straps to pass through.

[0017] In a preferred embodiment, a plurality of first reinforcing ribs are provided perpendicularly between the fixed plate and the first baffle, and a plurality of second reinforcing ribs are provided perpendicularly between the sliding plate and the second baffle.

[0018] In a preferred embodiment, the restraint frame further includes a movable tail frame, which is slidably connected to one of the sliding rods for securing the animal's tail.

[0019] In a preferred embodiment, the movable tailstock includes a third baffle and a movable plate vertically disposed on the third baffle; the bottom of the third baffle is bent along one side to form a movable groove together with the movable plate, and the bottom of the movable groove slides against the sliding rod.

[0020] In a preferred embodiment, a plurality of third reinforcing ribs are provided perpendicularly between the movable plate and the third baffle.

[0021] This invention provides a restraint frame for intratracheal inoculation of animals. The distance between the transverse side plate and the fixed side plate can be adjusted according to the size of the animal to be inoculated. Through the cooperation of positioning pins and the moving plate's fixing rod, the animal is placed back-down, and then secured with restraint straps to its belly. This prevents the animal from moving, as its limbs are facing upwards. Animals like pigs have no gripping points and must remain still, allowing the operator to easily inject the inoculum (such as a virulent strain of Mycoplasma hyopneumoniae) into the trachea using a syringe. Maintaining this position for a certain period allows the inoculum to quickly and accurately enter the lower respiratory tract via the trachea, preventing the strain from diverting into the esophagus due to the animal's struggle, thus reducing post-inoculation inflammation. Furthermore, this restraint frame allows for single-person operation without physically restraining the animal, significantly reducing physical exertion and increasing the success rate.

[0030] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are merely for explaining the present utility model and are not intended to limit the present utility model.

[0031] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0032] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0033] In this embodiment of the invention, a restraint frame 100 for intratracheal inoculation of animals is provided. This is a specialized restraint frame for animals 200 (e.g., pigs) used for intratracheal inoculation or infection with vaccines, drugs, or pathogens. The restraint frame keeps the pig's limbs facing upwards, with no gripping points, allowing it to calmly wait. This ensures that the inoculated material injected into the pig's trachea flows smoothly into its lungs, preventing the strain from diverting into the esophagus due to the pig's struggle, thus reducing the inflammatory effect after inoculation. Furthermore, using this restraint frame makes the injection process convenient and quick for staff.

[0034] like Figure 1 and Figure 2 As shown, the restraint frame 100 for intratracheal inoculation of animals includes: a base frame 10, a fixed side plate 20, a transverse side plate 30, a plate-shifting rod 40, a positioning pin 50, and multiple restraint straps 60.

[0035] Specifically, the base frame 10 is provided with several spaced sliding rods 11. When the pig or other animal 200 is being kept in a stable position, the pig's back is pressed against the multiple sliding rods 11, at which time the sliding rods 11 serve as a load-bearing element.

[0036] The base frame 10 includes a pair of supports 12. Each support 12 includes a horizontal bar 120, a first support bar 121, and a second support bar 122. The horizontal bar 120, the first support bar 121, and the second support bar 122 within the same support 12 form a triangle, causing the first support bar 121 to be inclined. The two ends of the sliding rod 11 are respectively fixed to the two first support bars 121. Furthermore, the second support bar 122 is perpendicular to the horizontal bar 120, thus forming a right-angled triangle with the first support bar 121.

[0037] It should be noted that the second support rod 122 can be rotatably set with the first support rod 121. When it is necessary to place animals such as pigs 200, the second support rod 122 is lowered so that the first support rod 121 is placed horizontally. After the animal 200 is fixed, the second support rod 122 can be raised so that the plane on which the first support rod 121 and multiple sliding rods 11 are located is tilted to tilt the animal 200 to the optimal angle (e.g., 45-50 degrees). This not only makes the animal 200 more comfortable but also avoids the backflow of the inoculum, which would cause the inoculation to fail. At the same time, the inoculum injected into the pig's trachea can flow smoothly into its lungs, so that the strain will not be diverted to the esophagus due to the pig's struggle, thereby reducing the inflammatory effect after inoculation.

[0038] The fixed side plate 20 is located on one side of the base frame 10. Specifically, the fixed side plate 20 includes a fixed plate 21 and a first baffle 22 vertically disposed on the fixed plate 21. The fixed plate 21 is fixed to a plurality of sliding rods 11, thereby making the first baffle 22 perpendicular to the plane in which the plurality of sliding rods 11 are located.

[0039] The lateral sliding side plate 30 is slidably connected to the sliding rod 11 to secure the animal 200 together with the fixed side plate 20. Specifically, in conjunction with Figure 2 As shown, the transverse side plate 30 includes a sliding plate 31 and a second baffle 32 vertically disposed on the sliding plate 31. At least one fixing sleeve 33 is provided on the side of the sliding plate 31 away from the second baffle 32. The fixing sleeve 33 is detachably fixed to the sliding plate 31 to form a sliding hole. The fixing sleeve 33 is sleeved onto a predetermined sliding rod 11 through this sliding hole, allowing the second baffle 32 to move closer to or further away from the first baffle 22 along the length of the sliding rod 11. Thus, depending on the size of the animal 200, the second baffle 32 and the first baffle 22 can together clamp the sides of the animal 200's body, preventing the animal 200 from moving its limbs.

[0040] Furthermore, a plurality of first reinforcing ribs (not shown in the figure) are vertically provided between the fixed plate 21 and the first baffle 22 to enhance the connection strength between the fixed plate 21 and the first baffle 22. A plurality of second reinforcing ribs 34 are vertically provided between the sliding plate 31 and the second baffle 32 to enhance the connection strength between the sliding plate 31 and the second baffle 32.

[0041] In this embodiment of the invention, one end of the moving plate fixing rod 40 is fixed to the transverse moving side plate 30 and is provided with a plurality of spaced-apart pin holes 401. A positioning pin 50 is inserted into one of the pin holes 401 and cooperates with the base frame 10 to fix the position of the transverse moving side plate 30. Specifically, one end of the positioning pin 50 passes through the pin hole 401 and extends into and abuts against the inner side of the first support rod 121. Because the animal 200's body exerts pressure on the transverse moving side plate 30 in a direction away from the fixed side plate 20, the positioning pin 50 is tightly pressed against the inner side of the first support rod 121. The first support rod 121, in turn, prevents the transverse moving side plate 30 from moving, ultimately achieving the clamping and fixing of the animal 200's body.

[0042] In this embodiment, multiple restraint straps 60 are used to restrain predetermined parts of the animal. For example, one restraint strap 60 restrains the animal's abdomen, one restraint strap 60 restrains the animal's chest, and one restraint strap 60 restrains the animal's neck. Specifically, one end of the restraint strap 60 is fixed to the side of the first baffle 22 away from the second baffle 32. The side of the second baffle 32 away from the first baffle 22 is provided with a fastening element (not shown in the figure). The restraint strap 60 is provided with a plurality of fastening holes 601. The fastening holes 601 are used to engage with the fastening element to fasten the restraint strap 60, thereby restraining the belly of the animal 200 to prevent the animal from detaching from between the first baffle 22 and the second baffle 32. The specific fastening hole 601 for fastening can be selected according to the size of the animal's body.

[0043] Furthermore, both the side of the first baffle 22 away from the sliding rod 11 and the side of the second baffle 32 away from the sliding rod 11 are provided with clearance grooves 602 corresponding to the restraint straps 60. The clearance grooves 602 are used for the corresponding restraint straps 60 to pass through, thereby preventing the restraint straps 60 from shifting laterally and improving the restraint effect of the restraint straps 60.

[0044] like Figure 3 As shown, the restraint frame 100 for intratracheal inoculation of animals also includes a movable tail support 70. The movable tail support 70 is slidably connected to one of the sliding rods 11 to secure the tail of the animal 200. It is understood that the animal 200 is typically placed at an angle with its head down, therefore the movable tail support 70 supports the animal's tail and rump, preventing the animal 200 from sliding down between the first baffle 22 and the second baffle 32. The movable tail support 70 can adjust its position by moving along the sliding rod 11.

[0045] Specifically, the movable tailstock 70 includes a third baffle 71 and a movable plate 72 vertically disposed on the third baffle 71. The bottom of the third baffle 71 is bent along one side to form a movable groove 701 together with the movable plate 72, and the bottom of the movable groove 701 slides against the sliding rod 11. Furthermore, a plurality of third reinforcing ribs 73 are vertically disposed between the movable plate 72 and the third baffle 71 to strengthen the connection between the movable plate 72 and the third baffle 71.

[0046] In summary, the restraint frame 100 for tracheal inoculation of animals provided by this utility model can adjust the distance between the transverse side plate 30 and the fixed side plate 20 according to the size of the animal 200 to be inoculated. Through the cooperation of the positioning pin 50 and the moving plate fixing rod 40, the animal 200 is placed with its back facing down. Then, the belly of the animal 200 is fastened and fixed by the restraint strap 60, so that the animal 200 can only have its limbs facing up and its body cannot move. The feet of animals such as pigs have no gripping points and can only wait calmly. It is convenient for the operator to inject the inoculation material (such as the virulent mycoplasma hyopneumoniae virus) into the trachea of ​​the pig or other animal 200 with a syringe. After the animal 200 is kept in a certain position for a certain period of time (for example, 3 min-5 min), the inoculation material can quickly and accurately enter the lower respiratory tract through the trachea, so as not to divert the virus to the esophagus due to the animal struggling, thereby reducing the inflammatory effect after inoculation. At the same time, this restraint frame can be operated by a single person without having to hold down animals such as pigs, which greatly reduces the physical intensity and demand and increases the success rate of the operation.

[0047] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
