Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an auxiliary needle insertion device and a rotary vaccine injection machine. Background Art

[0002] In the existing poultry vaccine injection technology, a horizontal syringe is generally used. This technology is provided with a specific groove and a corresponding needle. The operator needs to manually grab the neck of the poultry and squeeze it into the groove to form a bulge so that the needle can be accurately inserted into the bulge for vaccine injection; however, this method has the problem of low efficiency. The process of manually squeezing the poultry neck to form a bulge is time-consuming and laborious. Especially in a large-scale breeding environment, a large amount of human resources is required to complete the vaccine injection work, which greatly limits the injection efficiency;

[0003] At the same time, since the operator needs to squeeze the poultry into the groove, if the operation is improper, the moving needle is easy to pierce the operator's hand, and the piercing injury needs to be highly valued. For example, when injecting oil vaccine into poultry, the operator is pierced. A minor piercing injury may cause local paralysis of the hand, while a serious piercing injury may require surgery to remove the residual vaccine liquid, posing a threat to the health of the operator. Therefore, the prior art urgently needs an automated device that can improve the efficiency and safety of vaccine injection. Summary of the invention

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figure 1-13 As shown, the present invention discloses an auxiliary needle insertion device including a clamping mechanism 1, an injection mechanism 2 and a frame 3, wherein the clamping mechanism 1 is arranged on the frame 3, and the injection mechanism 2 is movably connected to the frame 3, and the clamping mechanism 1 includes a left arm 11 and a right arm 12 which are symmetrically arranged and can be opened and closed with each other, and a clamping part 19 and a clamping part 2 10 are arranged on the left arm 11 and the right arm 12, and a concave arc surface 111 and a concave arc surface 2 121 which are symmetrically arranged on the opposite surfaces of the clamping part 19 and the clamping part 2 10, and the concave arc surface 111 and the concave arc surface 2 121 enclose an injection area 13, and the injection mechanism 2 includes a needle head 21, and the needle head 21 is coaxially arranged corresponding to the injection area 13;

[0038] At least one of the clamping part 1 9 and the clamping part 2 10 is provided with a protrusion 100, and when the left arm 11 and the right arm 12 are clamped together, an isolation area 200 is formed between the protrusions to isolate the muscle from the injection area 13, so as to completely isolate the subcutaneous tissue from the muscle and the cervical vertebrae;

[0039] Before the injection mechanism 2 drives the needle 21 to move into the injection area 13, the clamping mechanism 1 is rotated from an open state to a clamping state, so that the poultry skin is clamped in the injection area 13 and a skin bulge that does not include cervical vertebrae and muscles is formed, and the needle 21 moves into the bulge for injection;

[0040] It should be noted that the injection area for some vaccines, especially oil-based vaccines, is strictly limited. The skin structure at the cervical vertebra of poultry is divided into epidermis, subcutaneous tissue, muscle and cervical vertebra from outside to inside, and this type of vaccine can usually only be injected into the subcutaneous tissue area of ​​poultry. In order to further improve the success rate of vaccine injection, the clamping mechanism 1 pinches the skin of the poultry to be injected to form a bulge, and the height of the bulge is basically consistent with the space of the injection area 13, and the needle insertion position is opposite to the bulge. Since the clamping part 1 9 and the clamping part 2 10 are provided with a protrusion 100, when the protrusion is pinched, an isolation area 200 for isolating the protrusion and the muscle is formed between the protrusions 100. At this time, the protrusions are all subcutaneous tissue; the setting of the protrusion 100 and the isolation area 200 can effectively physically isolate the subcutaneous tissue from the muscle or cervical vertebra, completely avoiding the risk of the needle 21 entering the muscle or cervical vertebra, thereby improving the accuracy and stability of the injection.

[0041] It should be noted that the isolation area 200 is not directly formed by the protrusions 100 , but is formed by the skin when the skin is clamped by the protrusions 100 and squeezed by the protrusions 100 .

[0042] Specifically, when the injection mechanism 2 is not subjected to an external force or a driving mechanism, the injection mechanism 2 does not move relative to the frame 3, and the clamping mechanism 1 is in an open state, so that the poultry to be injected can be placed in or removed from the grasping range of the clamping mechanism 1; in the open state, the opening angle between the left arm 11 and the right arm 12 of the clamping mechanism 1 is usually the largest to ensure that there is enough space to clamp the poultry to be injected, and the needle 21 is farthest from the injection area 13; when the injection mechanism 2 is subjected to an external force or a driving mechanism, the injection mechanism 2 descends, and the injection Before the mechanism 2 drives the needle 21 to move into the injection area 13, the clamping mechanism 1 is rotated and switched from an open state to a clamping state under the action of the injection mechanism 2. At this time, the clamping state means that the left arm 11 and the right arm 12 of the clamping mechanism 1 are close to or in contact with each other, thereby grasping or clamping the poultry to be injected and pinching its skin to a certain extent, so that the subcutaneous tissue of the poultry's epidermis is separated from the muscles or cervical vertebrae. In the clamping state, the angle between the left arm 11 and the right arm 12 of the clamping mechanism 1 is small, so as to tightly and firmly grasp the neck of the poultry.

[0043] like Figure 4As shown, a fastener 31 is fixedly arranged at the bottom of the frame 3, the left arm 11 includes a first connecting portion 112 arranged horizontally, and the right arm 12 includes a second connecting portion 122 arranged horizontally, and the first connecting portion 112 and the second connecting portion 122 are both provided with a coaxially arranged through hole 14, and the fastener 31 is penetrated in the through hole 14; during installation, the left arm 11 and the right arm 12 can be limitedly moved relative to the frame 3 or fixed at a specific position through the design of the first connecting portion 112 and the second connecting portion 122, and the coaxial arrangement of the through hole 14 ensures the alignment accuracy of the first connecting portion 112 and the second connecting portion 122 during connection, thereby ensuring the symmetry and balance of the entire structure, and at the same time, the first connecting portion 112 and the second connecting portion 122 can also rotate relative to each other to ensure the stability of the structure and the reliability of operation;

[0044] Furthermore, the fastener 31 can be a bolt or a screw. Through the setting of the fastener 31, the installation structure of the left arm 11, the right arm 12 and the frame 3 is simplified, effectively improving the efficiency and convenience of installation, maintenance and replacement of the left arm 11 and the right arm 12.

[0045] Preferably, the fastener 31 is connected to the through hole 14 via threads, so as to facilitate installation and removal of the fastener 31 and ensure the connection stability between the fastener 31 and the frame 3 .

[0046] Specifically, a limiting step 311 is provided at the bottom of the fastener 31, a first gasket 312 is provided between the first connecting portion 112 and the bottom of the frame 3, and a second gasket 313 is provided between the second connecting portion 122 and the limiting step 311; when in use, the first gasket 312 and the second gasket 313 play the role of reducing friction, improving the service life and preventing the fastener 31 from loosening when the first connecting portion 112 and the second connecting portion 122 rotate;

[0047] Furthermore, in order to improve the rotational flexibility of the first connecting part 112 and the second connecting part 122, a first elastic member 314 is also compressed between the second gasket 313 and the limiting step 311; the first elastic member 314 can be a spring or elastic rubber material, which is designed to provide the necessary preload force to keep the clamping mechanism 1 more flexible in reliable switching between the clamping state and the open state, while absorbing the impact and vibration generated during operation.

[0048] like Figure 5 As shown, a conical surface 22 with a diameter increasing from top to bottom is provided on the peripheral wall of the injection mechanism 2. The diameter of the conical surface 22 increases from top to bottom, forming a smooth transitional curved surface. This design not only ensures the smoothness of the clamping mechanism 1 during the clamping and opening process, but also helps to reduce friction and wear during operation.

[0049] Furthermore, the first connecting portion 112 and the second connecting portion 122 are provided with a semi-arc surface 113 and a semi-arc surface 2 123 respectively on the opposite surfaces thereof, which are arranged to abut against the conical surface 22; wherein, when the semi-arc surface 113 and the semi-arc surface 2 123 abut against the upper peripheral wall of the conical surface 22 together, the clamping mechanism 1 is in a clamping state, at which time the left arm 11 and the right arm 12 are close to each other, so as to achieve a firm clamping of the target poultry. On the contrary, when the semi-arc surface 113 and the semi-arc surface 2 123 abut against the lower peripheral wall of the conical surface 22 together, the clamping mechanism 1 is converted into an open state, at which time the left arm 11 and the right arm 12 are away from each other, allowing the target poultry to be put in or taken out.

[0050] like Figure 6 As shown, a second elastic member 15 is provided between the left arm 11 and the right arm 12, one end of the second elastic member 15 is fixedly connected to the left arm 11, and the other end is fixedly connected to the right arm 12, so that the clamping mechanism 1 tends to maintain a clamping state. In the design of the clamping mechanism 1, the second elastic member 15 can be a spring. The introduction of the second elastic member 15 is to provide a continuous clamping tendency force between the left arm 11 and the right arm 12, which can prevent the clamping mechanism 1 from accidentally opening due to vibration or other external forces during the clamping process. This design ensures that the clamping mechanism 1 can maintain its clamping state even in the presence of external loads or interference, thereby improving the stability and reliability of the clamping.

[0051] like Fig.13 As shown, the present invention also provides a second embodiment, the peripheral wall of the injection mechanism 2 is provided with a conical surface 22 whose diameter decreases from top to bottom, and the diameter of the conical surface 22 decreases from top to bottom to form a smooth transitional curved surface, and the first connecting portion 112 and the second connecting portion 122 are respectively provided with a semi-arc surface 113 and a semi-arc surface 2123 disposed to abut against the conical surface 22 on the opposite surfaces; wherein, when the semi-arc surface 113 and the semi-arc surface 2123 abut against the upper peripheral wall of the conical surface 22 together, the clamping mechanism 1 is in an open state, at which time the left arm 11 and the right arm 12 are away from each other, allowing the target poultry to be put in or taken out. On the contrary, when the semi-arc surface 113 and the semi-arc surface 2123 abut against the lower peripheral wall of the conical surface 22 together, the clamping mechanism 1 is converted into a clamping state, at which time the left arm 11 and the right arm 12 are close to each other, achieving a firm clamping of the target poultry.

[0052] It should be noted that, in the first embodiment, the conical surface 22 whose diameter increases from top to bottom moves downward so that the semi-arc surface 1 13 and the semi-arc surface 2 123 abut against the upper wall of the conical surface 22, so that the left arm 11 and the right arm 12 simultaneously approach each other and drive the clamping part 1 9 and the clamping part 2 10 to be in a clamping state;

[0053] On the contrary, in the second embodiment, the conical surface 22 whose diameter decreases from top to bottom moves downward so that the semi-arc surface 113 and the semi-arc surface 23 are in contact with the upper wall of the conical surface 22, so that the ends of the left arm 11 and the right arm 12 close to the conical surface 22 are opened, and the ends away from the conical surface 22 drive the clamping part 1 9 and the clamping part 2 10 to approach each other and present a clamping state;

[0054] Therefore, the implementation purpose of the above two embodiments is to enable the downward movement of the injection mechanism 2 to drive the clamping mechanism 1 to clamp, so under the same effect, the technical solutions that the upward or downward movement of the injection mechanism 2 can synchronously drive the clamping mechanism 1 to open or clamp are all within the protection scope of this application.

[0055] like Figure 8-9 As shown, the auxiliary needle insertion mechanism also includes a synchronization mechanism 4, which includes a symmetrically arranged left support member 41 and a right support member 42, the left support member 41 is provided with a fixing hole 161, and the right support member 42 is provided with a fixing hole 162. The first connecting portion 112 is provided with a limiting hole 114 coaxially corresponding to the fixing hole 161, and the second connecting portion 122 is provided with a limiting hole 124 coaxially corresponding to the fixing hole 162. The first connecting portion 112 and the second connecting portion 122 include a locking member 7, and the locking member 7 is inserted in the fixing hole 161 and the limiting hole 114, and the locking member 7 is inserted in the fixing hole 162 and the limiting hole 124. The left support member 41 is provided with a fixing hole 161, and the right support member 42 is provided with a fixing hole 162. One end of the member 41 is rotatably connected to the bottom of the first connecting part 112, and one end of the right support member 42 is rotatably connected to the bottom of the second connecting part 122; the left support member 41 is provided with a positioning hole 1 413, and the right support member 42 is provided with a positioning hole 2 423, and both the positioning hole 1 413 and the positioning hole 2 423 are inserted with an axle pin 19, and the first connecting part 112 and the second connecting part 122 are provided with coaxial corresponding avoidance holes 18, the diameter of the avoidance holes 18 is larger than the diameter of the axle pin 19, and the axle pin 19 does not interfere with the movement of the left arm 11 and the right arm 12, and the other end of the left support member 41 is rotatably connected to the bottom of the frame 3; the other end of the right support member 42 is rotatably connected to the bottom of the frame 3.

[0056] Further, such as Fig. 9As shown, one end of the left support member 41 rotatably connected to the frame 3 is provided with a gear tooth 1 411, and one end of the right support member 42 rotatably connected to the frame 3 is provided with a gear tooth 2 421, and the gear tooth 1 411 is meshed with the gear tooth 2 421. This design enables the left arm 11 and the right arm 12 to perform precise synchronous relative movement relative to the frame 3 to achieve the synchronous clamping or opening function of the left arm 11 and the right arm 12.

[0057] like Fig.10 As shown, a connecting hole 32 is provided in the frame 3, and the injection mechanism 2 is inserted into the connecting hole 32 to ensure that the injection mechanism 2 is correctly positioned in the connecting hole 32 and limit its axial movement. A first limiting ring 321 is fixedly provided in the connecting hole 32, and a second limiting ring 322 is fixedly provided on the outer peripheral wall of the injection mechanism 2 and located above the first limiting ring 321. A third elastic member 33 is elastically compressed between the first limiting ring 321 and the second limiting ring 322. The third elastic member 33 can be a spring. The third elastic member 33 provides a restoring force for the injection mechanism 2, which helps to maintain the position of the injection mechanism 2 during operation and to move upward and reset without being affected by external force or other driving mechanisms.

[0058] Preferably, if Figure 1 As shown, the opposite surfaces of the ends of the left arm 11 and the right arm 12 are provided with "V"-shaped sections which are symmetrically arranged up and down, so that when the clamping claw mechanism 1 is in a clamping state, these "V"-shaped sections correspond to each other and form a narrow groove. When the skin of the injected poultry is clamped and raised, due to the design of the "V"-shaped section, it is adapted to the fluid design of the raised surface of the skin tissue, thereby increasing the comfort of the injected poultry during the process of clamping the skin during injection.

[0059] The present invention discloses a rotary vaccine injection machine. Figure 11-12 As shown, it includes a conveying mechanism 5, a fixing position 6 and the auxiliary needle insertion device. The conveying mechanism 5 includes a driving mechanism and a chain 51. The driving mechanism provides power for the transmission of the chain 51 so that the chain 51 can be continuously transmitted. The chain 51 is also provided with a plurality of fixing positions 6 arranged at intervals. When working, along with the transmission of the chain 51, the plurality of fixing positions 6 are transported one by one toward the auxiliary needle insertion device. Poultry is placed in the fixing position 6, and the poultry in the fixing position 6 is transported to the auxiliary needle insertion device for injection.

[0060] When in use, the design of the fixed position 6 is intended to provide stability support and fixation for the poultry. The setting of the fixed position 6 not only improves the accuracy of needle insertion and saves the labor cost of manually placing the poultry on the needle 21 for injection, but also improves the production efficiency of the entire rotary equipment to ensure that when each fixed position 6 reaches the predetermined position, the needle can be automatically inserted and injected; therefore, this automated rotary needle insertion method not only improves production efficiency, but also optimizes the operating steps of the operator, and effectively improves the operating safety of the operator.

[0061] The working principle of the present invention is described in detail below;

[0062] The poultry to be injected is fixed on the fixed position 6, and the fixed position 6 is transported one by one toward the auxiliary needle insertion device along with the transmission of the chain 51. When the fixed position 6 reaches the position of the auxiliary needle insertion device, the injection mechanism 2 moves downward and drives the clamping mechanism 1 to rotate from the open state to the clamping state. The clamping mechanism 1 pinches the skin of the poultry to be injected to form a bulge of a certain length. When the needle 21 on the injection mechanism 2 moves into the injection area 13, the needle insertion position is opposite to the bulge, thereby effectively isolating the skin from the muscle or cervical vertebrae, completely avoiding the risk of hitting the muscle or cervical vertebrae, and thus improving the accuracy and stability of the injection;

[0063] After the injection is completed, the injection mechanism 2 moves upward under the elastic force of the third elastic member 33, and at the same time drives the clamping mechanism 1 to rotate again and switch to the open state to release the skin of the poultry; then, the conveying mechanism 5 continues to convey the next fixed position 6 to the position of the auxiliary needle insertion device, and this process is repeated to realize continuous automated injection operation on the rotary type; the above-mentioned rotary working principle realizes the efficient operation of automated injection, ensures accurate positioning and stable clamping during the injection process, and continuous conveying and positioning of the poultry to be injected, greatly improves production efficiency, reduces labor costs, and is suitable for large-scale production environments.

[0064] The innovation of the present invention is that the concave arc surface 1 111 and the concave arc surface 2 121 form an injection area 13, and the needle 21 is coaxially arranged corresponding to the injection area 13; before the injection mechanism 2 drives the needle 21 to move into the injection area 13, the clamping mechanism 1 is rotated from an open state to a clamping state under the action of the injection mechanism 2, so that tissues other than muscle tissues are clamped in the injection area 13, thereby improving the accuracy and stability of injection;

[0065] The injection mechanism 2 and the clamping mechanism 1 adopt a linkage design. When the injection mechanism 2 is subjected to external force or other driving mechanisms move, the clamping mechanism 1 can be automatically driven to clamp by driving the injection mechanism 2 to move, so that the clamping action of the clamping mechanism 1 is more automated, and the matching error with the needle 21 when moving is smaller;

[0066] The auxiliary needle insertion device and the rotary vaccine injection machine can perform batch automated vaccine injections on poultry, significantly improving the efficiency of vaccination. Vaccine injections by machine can reduce manual injection costs, thereby avoiding the risk of operators being pricked by the needle 21 during the injection process.

[0067] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0068] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
