Description

Technical Field

[0001] This utility model belongs to the technical field of vaccine production equipment, and in particular relates to a chicken heart blood collection positioning device. Background Technology

[0002] In the vaccine production cycle, SPF animals are usually used. SPF (Specific Pathogen Free) animals are laboratory animals that do not carry major potential infectious agents or conditional pathogens or pathogens that greatly interfere with scientific experiments, except for pathogens that should be excluded from clean animals. Chickens are usually used as experimental subjects in the vaccine production cycle.

[0003] In the fields of laboratory chicken research, breeding, and quarantine, blood collection from experimental chickens is an essential step. During blood collection, the chickens need to be restrained to expose the blood collection site for the procedure. Therefore, restraint devices are typically used. Currently, there are some poultry blood collection restraint devices on the market. Structurally, these typically consist of a flat plate with several elastic ropes connected to it. The free ends of the elastic ropes are connected to hooks, and the plate has several small holes for the hooks to engage, allowing the elastic ropes to compress the chicken's torso.

[0004] However, in practical work, it was found that using the aforementioned elastic ropes to fix poultry has several drawbacks. The ropes may be too tight, causing excessive pressure and resulting in the poultry struggling violently, thus affecting the blood collection process. Conversely, if the ropes are too loose, they cannot effectively fix the poultry, also affecting the blood collection process. Furthermore, the shape and hole positions of existing poultry blood collection fixation devices are usually fixed, failing to adequately adapt to the fixation needs of poultry of different sizes. Therefore, there is an urgent need to design a chicken heart blood collection positioning device to solve these problems. Summary of the Invention

[0005] This invention provides a chicken heart blood collection positioning device with a reasonable structural design to solve the technical problems existing in the prior art. This invention can effectively bind and fix experimental chickens of different sizes, avoiding excessive pressure or strangulation, and facilitating stable fixation for blood collection operations on experimental chickens of different sizes.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A chicken heart blood collection positioning device includes an operating bracket, a mounting plate rotatably connected to the operating bracket, the mounting plate being stepped, and a flipping drive assembly for driving the mounting plate to flip; a mounting slot is opened on the high step surface of the mounting plate, and a support plate is provided in the middle area of ​​the mounting slot, and a front binding assembly is provided inside the mounting slot; an adjustable mounting seat and a position adjustment assembly for driving the adjustable mounting seat to move toward / away from the front binding assembly are provided on the low step surface of the mounting plate, a mounting groove is opened in the middle area of ​​the adjustable mounting seat, and a support plate is provided in the middle of the mounting groove, and a support plate is provided inside the mounting groove. The system includes a rear binding component with the same structure as the front binding component. An operation window is provided on the high step surface of the mounting plate, containing an adjustable blood collection positioning mechanism for inserting a blood collection syringe.

Since the rotational operation tension adjustment mechanism can drive the corresponding binding wheel to rotate, the binding can be wound / unwound, thereby tightening / loosening the binding degree of the experimental chicken, avoiding excessively loose or tight fixation. Furthermore, since the spacing adjustment mechanism can adjust the distance between the two binding moving seats, and the position adjustment component can adjust the front... The spacing between the binding components and the rear binding components ensures that this invention can effectively accommodate the fixation needs of experimental chickens of different sizes, improving the applicability of the positioning device. The intermediate binding component allows for the binding and fixation of the chicken's wings. The flipping drive component allows for the flipping of the mounting plate, facilitating the vertical rotation of the bound chicken so that its breast faces upwards, thus facilitating subsequent cardiac blood collection. The adjustable blood collection positioning mechanism allows for the positioning of the blood collection syringe, further facilitating cardiac blood collection.

[0016] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided in detail: Please see Figure 1 The chicken heart blood collection positioning device of this utility model includes an operating bracket 6, a mounting plate 4 rotatably connected to the operating bracket 6, the mounting plate 4 being stepped, and a flipping drive assembly 11 for driving the mounting plate 4 to flip; an installation slot 2 is provided on the high step surface of the mounting plate 4, and a support plate 1 is provided in the middle area of ​​the installation slot 2, and a front binding assembly 3 is provided in the installation slot 2.

[0017] In addition, an adjustable mounting base 7 and a position adjustment component 9 for driving the adjustable mounting base 7 to move toward / away from the front binding component 3 are provided on the low step surface of the mounting base plate 4. A mounting groove is provided in the middle area of ​​the adjustable mounting base 7 and a support plate 2 10 is provided in the middle of the mounting groove. It also includes a rear binding component 8 provided in the mounting groove. The structure of the rear binding component 8 is the same as that of the front binding component 3.

[0018] Furthermore, an operation window 12 is provided on the high step surface of the mounting base plate 4, and an adjustable blood collection positioning mechanism 13 is provided in the operation window 12 for inserting a blood collection needle; it also includes two sets of intermediate binding components 5 respectively located on both sides of the operation window 12 and installed on the mounting base plate 4.

[0019] like Figure 3 As shown, the aforementioned front binding assembly 3 includes two binding movable seats 3-2 arranged opposite to each other. Each binding movable seat 3-2 is rotatably connected to an axle, and a binding wheel 3-4 is keyed to the axle. It also includes binding straps with both ends wrapped around the two binding wheels 3-4 respectively. It also includes a tension adjustment mechanism 3-3 installed on each binding movable seat 3-2 for driving the corresponding binding wheel 3-4 to rotate. It also includes a spacing adjustment mechanism for adjusting the spacing between the two binding movable seats 3-2.

[0020] See further Figure 4The aforementioned tension adjustment mechanism 3-3 includes an outer protective shell 3-3-1 mounted on the corresponding binding movable seat 3-2 and covering the axle, with an outer protective sleeve 3-3-2 fixedly connected to the outer protective shell 3-3-1; it also includes an adjustment knob 3-3-3 passing through and rotatably connected to the outer protective sleeve 3-3-2, with an adjustment bevel gear 3-3-4 keyed to the lower end of the adjustment knob 3-3-3, and an adjustment bevel gear 3-3-5 keyed to the corresponding axle and meshing with the adjustment bevel gear 3-3-4. In actual operation, the operator rotates the adjustment knob 3-3-3, which drives the adjustment bevel gear 3-3-4 mounted on it to move, thereby driving the adjustment bevel gear 3-3-5 and the corresponding axle to rotate, achieving the purpose of rotating the corresponding strap wheel 3-4. The rotating strap wheel 3-4 can achieve the purpose of winding / unwinding the strap, thus tightening / loosening the strap to secure the experimental chicken during operation.

[0021] In addition, such as Figure 3 As shown, the aforementioned spacing adjustment mechanism includes a horizontally arranged left- and right-hand lead screw 3-5, with two binding movable seats 3-2 connected to the left- and right-hand lead screw 3-5 respectively via corresponding nuts; a worm gear 3-6 is keyed to the middle of the left- and right-hand lead screw 3-5, and a worm 3-1 is also arranged horizontally and perpendicular to the left- and right-hand lead screw 3-5, meshing with the worm gear 3-6; an operating handwheel is installed at the outer end of the worm 3-1. The left- and right-hand lead screw 3-5 and the worm 3-1 in the front binding assembly 3 are rotatably connected to the mounting base plate 4, and the left- and right-hand lead screw and the worm in the rear binding assembly 8 are rotatably connected to the adjustable mounting base 7.

[0022] The neck of the experimental chicken can be bound and fixed by the combination of the support plate 1 and the front binding component 3. The body of the experimental chicken can be bound and fixed by the combination of the rear binding component 8 and the support plate 10. Since the rotation operation tension adjustment mechanism 3-3 can drive the corresponding binding wheel 3-4 to rotate, the binding can be wound / unwound, thereby tightening / loosening the binding of the experimental chicken and avoiding the binding of the experimental chicken being too loose or too tight. Since the spacing adjustment mechanism can adjust the spacing between the two binding moving seats 3-2, and the position adjustment component 9 can adjust the spacing between the front binding component 3 and the rear binding component 8, this utility model can well adapt to the fixing needs of experimental chickens of different sizes, improving the applicability of the positioning device.

[0023] See further Figure 2The aforementioned blood collection positioning mechanism 13 includes two locking strip holes 13-1 distributed on both sides of the operating window 12 on the mounting base plate 4, and a blood collection moving base 13-2 locked to the mounting base plate 4 by bolts passing through the locking strip holes 13-1. A blood collection outer sleeve 13-3 located inside the operating window 12 is installed on the blood collection moving base 13-2. A blood collection inner rotating sleeve 13-4 rotatably connected to the blood collection outer sleeve 13-3 is installed inside the blood collection outer sleeve 13-3. The mechanism also includes a blood collection sleeve 13-5 that penetrates the blood collection inner rotating sleeve 13-4, the blood collection outer sleeve 13-3, and the blood collection moving base 13-2 and is installed at the eccentric part of the blood collection inner rotating sleeve 13-4.

[0024] By setting an adjustable blood collection positioning mechanism 13, the blood collection needle inserted on the blood collection positioning mechanism 13 can be positioned, thereby facilitating the heart blood collection operation of the experimental chicken. The blood collection sleeve 13-5 is eccentrically set with the blood collection inner rotating sleeve 13-4, and its optimal position is that it is internally tangent to the blood collection inner rotating sleeve 13-4. When the blood collection inner rotating sleeve 13-4 is rotated, the blood collection sleeve 13-5 rotates around the center of the blood collection outer sleeve 13-3, forming a circular motion trajectory within the blood collection outer sleeve 13-3 to locate the specific position of the experimental chicken's heart. The rotation trajectory of the blood collection sleeve 13-5 intersects with the position of the experimental chicken's heart. When the blood collection sleeve 13-5 rotates to the position of the experimental chicken's heart, the blood collection needle is inserted into the blood collection sleeve 13-5, so that the blood collection needle is directly facing the experimental chicken's heart for blood collection.

[0025] See further Figure 2 The aforementioned position adjustment assembly 9 includes two guide rod supports 9-1 mounted on the low-step surface of the mounting plate 4. A plurality of sliding guide rods 9-2 are fixedly connected between the two guide rod supports 9-1, linking them together. It also includes a slide block slidably connected to the sliding guide rods 9-2, with an adjustable mounting base 7 mounted on the slide block. Furthermore, it includes an adjusting screw 9-3 rotatably connected between the two guide rod supports 9-1 and arranged parallel to the sliding guide rods 9-2. The slide block is connected to the adjusting screw 9-3 via a nut, and a handwheel is mounted on the outer end of the adjusting screw 9-3. The sliding guide rods 9-2 and the locking strip hole 13-1 extend in the same direction, pointing vertically forward towards the binding assembly 3.

[0026] In addition, a groove is provided on the high step surface of the mounting base plate 4, and the operation window 12 is provided in the groove. In this embodiment, the top surface of the second support plate 10 and the top surface of the first support plate 1 are both flush with the high step surface of the mounting base plate 4.

[0027] See further Figure 5The aforementioned intermediate binding assembly 5 includes two parallel mounting guide rods 5-1 mounted on the mounting base plate 4. A plurality of binding rods 5-5 are mounted between the two mounting guide rods 5-1 via mounting sleeves 5-3. Each mounting sleeve 5-3 is fitted with a bolt that abuts against the mounting guide rod 5-1. An intermediate binding strap 5-4 is mounted on each binding rod 5-5. Several slotted holes are provided on the binding rods 5-5 for adjusting the fixed end and slotted end of the intermediate binding strap 5-4. The intermediate binding strap 5-4 is a snap-fit ​​binding strap, including a strap body, a fixing block mounted at one end, an insert at the other end, and a slotted block that engages with the insert. Both the fixing block and the slotted block are locked to the corresponding binding rod 5-5 by bolts passing through the slotted holes.

[0028] The intermediate binding assembly 5 also includes several pairs of mounting blocks fixed to the mounting base plate 4. Each mounting guide rod 5-1 is installed between two mounting blocks, and a mounting connecting rod 5-2 connects the two outer mounting blocks. During the wing binding process of the experimental chicken, the wings are placed on several binding rods 5-5, and then the inserts of the intermediate binding straps 5-4 are inserted into the corresponding slot blocks, thereby achieving wing binding and fixation. Through the above settings, the intermediate binding assembly 5 can be well adapted to the fixation needs of experimental chickens of different sizes, improving the applicability of the positioning device.

[0029] See further Figure 6 The aforementioned flip drive assembly 11 includes two flip shafts 11-6 rotatably connected to the operating bracket 6 and arranged coaxially. A flip shaft seat 11-3 for mounting the mounting plate 4 is fixedly connected to the inner end of each flip shaft 11-6. It also includes a drive shaft 11-2 rotatably connected to the operating bracket 6 and corresponding to each of the two flip shafts 11-6. A transmission gear pair 11-1 is installed between the corresponding drive shaft 11-2 and the flip shaft 11-6. The transmission gear pair 11-1 includes a driving gear keyed to the inner end of the drive shaft 11-2 and a driven gear keyed to the flip shaft 11-6 that meshes with the driving gear. A pin sleeve 11-5 is installed on the flip shaft 11-6. A plurality of evenly distributed pin holes are formed on the outer peripheral wall of the pin sleeve 11-5. It also includes a positioning pin 11-4 that passes through the operating bracket 6 and engages with the pin holes. Finally, it includes a flip handwheel 11-7 installed at the outer end of the drive shaft 11-2.

[0030] Working principle: In actual operation, the front binding component 3 can be used to bind and fix the neck of the experimental chicken, and the rear binding component 8 can be used to bind and fix the body of the experimental chicken. During the binding and fixing process, the position of the adjustable mounting base 7 can be adjusted according to the size of the experimental chicken to ensure that the rear binding component 8 can effectively bind and fix the body of the experimental chicken. During the binding process, the operator rotates the adjustment knob 3-3-3, which drives the first adjustment bevel gear 3-3-4 installed on it to move, thereby driving the second adjustment bevel gear 3-3-5 and the corresponding wheel axle to rotate, so as to drive the corresponding binding wheel 3-4 to rotate. The rotating binding wheel 3 -4 can achieve the purpose of winding / unwinding the straps, thereby tightening / loosening the straps to fix the experimental chickens during the working process, thus ensuring that the experimental chickens are properly fixed; since the spacing adjustment mechanism can adjust the spacing between the two binding moving seats 3-2, it can ensure that the front binding component and the rear binding component in this utility model can well adapt to the fixing needs of experimental chickens of different sizes, thus improving the applicability of the positioning device; after the neck and body of the experimental chicken are fixed, the wings of the experimental chicken are fixed using the two intermediate binding components 5. After the binding operation of the experimental chicken is completed, the chicken's chest and heart are within the operation window 12; Then, the mounting base plate 4 is flipped using the flip drive assembly 11, i.e., the flip handwheel 11-7 in the flip drive assembly 11 is rotated to flip the mounting base plate 4 up and down and fix the position of the mounting base plate 4. Then, the lateral position of the blood collection moving seat 13-2 is moved and the blood collection inner sleeve 13-4 is rotated so that the blood collection sleeve 13-5 is rotated to the position of the experimental chicken's heart. Then, the blood collection needle is inserted into the blood collection sleeve 13-5 so that the blood collection needle is directly facing the experimental chicken's heart to perform blood collection.
