Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an auxiliary injection detection method. Background Art

[0002] In the process of poultry vaccination, poultry are usually vaccinated by machine or manually. Since effective automatic detection and automatic injection methods are not used in the prior art, it is always necessary to manually detect the vaccination status of poultry;

[0003] During manual inspection, it is usually necessary to mix a biological dye that is harmless to poultry into the vaccine solution. The vaccine injected into the subcutaneous tissue of the poultry can produce a significant color change to distinguish whether the vaccine injection is successful. However, most poultry usually have thick feathers covering their outer skin, so the feathers need to be manually parted to see the injection site. At the same time, the number of poultry is huge, and manual inspection can only be performed through sampling inspection, which leads to differences between the test results and the actual vaccine injection situation. Therefore, manual inspection is not only time-consuming and labor-intensive, but also there is a problem of large deviation between the test results and the actual results. Summary of the invention

[0005] The invention discloses an auxiliary injection detection method, aiming to solve the problems of low detection efficiency and low detection result accuracy in the prior art through manual detection.

[0006] (2) Technical solution

[0007] The present invention discloses an auxiliary injection detection method, comprising a frame, a syringe and a clamping mechanism, wherein the syringe is movably connected to the frame, the clamping mechanism is arranged on the frame, and the clamping mechanism comprises a pair of symmetrically arranged clamping arms, the clamping arms can be moved closer to or farther from each other to clamp the skin;

[0008] At least one of the clamping arms has a protrusion at its end, and when the clamping mechanism clamps the skin, an isolation zone is formed between the protrusions to isolate the muscles from the clamping area, so as to completely isolate the subcutaneous tissue clamped in the clamping area from the muscles and the cervical vertebrae;

[0009] The frame is also provided with a detection mechanism, which includes a sensing element, and the sensing element is arranged on a side close to the clamping area of ​​the clamping arm;

[0010] The specific detection steps are as follows:

[0011] Step 1: Clamp the skin with the clamping arm in the clamping mechanism, so that the skin in the clamping area forms a raised wrinkle of subcutaneous tissue, wherein the wrinkle includes a wrinkle top and a wrinkle bottom; in the clamping state, the wrinkle bottom abuts against the sensing surface of the sensing element;

[0012] Step 2: Move the syringe so that the needle of the syringe enters the fold and is located between the top and bottom of the fold, and then inject the liquid medicine into the fold through the needle; after the liquid medicine injection is completed, the needle is withdrawn from the fold, and then the clamp arms are separated from each other and detached from the skin;

[0013] During the injection of the liquid medicine, the liquid medicine causes the folds to expand and squeeze the sensing element, causing the sensing element to generate a signal. If the change value of the signal reaches or exceeds the set threshold, the detection result is a successful injection; otherwise, the injection is unsuccessful.

[0014] Furthermore, during the injection of the liquid medicine, the sensing element is started while the liquid medicine is injected into the folds; and the sensing element is stopped synchronously when the injection stops.

[0015] Furthermore, the sensing surface is designed to be inclined, and the inclination angle of the sensing surface is adapted to the inclination angle of the pleat bottom.

[0016] Furthermore, the sensing element is a pressure sensor.

[0017] Furthermore, the clamp arm includes a longitudinal arm and a transverse arm, one end of the transverse arm is fixedly connected to the top end of the longitudinal arm, and the other end is rotatably connected to the frame; symmetrically arranged arc-shaped concave surfaces are provided on the opposite surfaces of the two transverse arms, and the two concave surfaces form a through hole, and the syringe is inserted into the through hole.

[0018] Furthermore, the peripheral wall of the syringe is provided with a conical surface abutting against the through hole, the conical surface includes an upper portion and a lower portion arranged vertically, and the outer wall diameter D1 of the lower portion is greater than the outer wall diameter D2 of the upper portion.

[0019] Furthermore, a first elastic member is provided between the two longitudinal arms, and two ends of the first elastic member are respectively fixedly connected to the two longitudinal arms, so that the two clamping arms tend to maintain a clamping state.

[0020] Furthermore, a connecting hole is provided in the frame, and the syringe is slidably connected in the connecting hole. A first step is provided on the peripheral wall of the syringe, and a second step is fixedly provided in the connecting hole and below the first step. A second elastic member is pressed between the first step and the second step.

[0021] Furthermore, in the connecting hole, at least one sealing ring is fixedly provided on the peripheral wall of the syringe.

[0022] Furthermore, the detection mechanism also includes a fixing rod, one end of which is fixedly connected to the frame, and the other end of which is fixedly connected to the sensing element.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] By arranging a pressure sensor below the clamping area and clamping the skin with a clamping mechanism to form raised wrinkles on the skin, the bottom of the wrinkles is kept in contact with the pressure sensor, thereby effectively improving the detection accuracy of the pressure sensor;

[0025] At the same time, by detecting the pressure changes of the pressure sensor during the injection process to determine whether the injection is successful, it can not only effectively improve the timeliness of the detection to obtain the test results faster, but also further improve the detection accuracy and comprehensiveness of the detection.

DETAILED DESCRIPTION

[0040] 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.

[0041] like Figure 1-3 As shown, the present invention discloses an auxiliary injection detection method, comprising a frame 1, a syringe 2 and a clamping mechanism 3, wherein the syringe 2 is movably connected to the frame 1, the clamping mechanism 3 is arranged on the frame 1, and the clamping mechanism 3 comprises a pair of symmetrically arranged clamping arms 31, and the clamping arms 31 can be moved closer to or farther from each other to clamp the skin;

[0042] At least one of the clamping arms 31 has a protrusion 312 at its end. When the clamping mechanism 3 clamps the skin, an isolation area 35 is formed between the protrusions 312 to isolate the muscles from the clamping area 311, so as to completely isolate the subcutaneous tissue clamped in the clamping area 311 from the muscles and the cervical vertebrae.

[0043] The frame 1 is further provided with a detection mechanism 4, and the detection mechanism 4 includes a sensing element 41, and the sensing element 41 is arranged on a side close to the clamping area 311 of the clamping arm 31;

[0044] The specific detection steps are as follows:

[0045] Step 1: Clamp the skin with the clamping arm 31 in the clamping mechanism 3, so that the skin in the clamping area 311 forms a raised wrinkle 5 of subcutaneous tissue, wherein the wrinkle 5 includes a wrinkle top 51 and a wrinkle bottom 52; in the clamping state, the wrinkle bottom 52 abuts against the sensing surface 411 of the sensing element 41;

[0046] Step 2: Move the syringe 2 so that the needle 21 of the syringe 2 enters the fold 5 and is located between the fold top 51 and the fold bottom 52, and then inject the drug solution into the fold 5 through the needle 21; after the injection of the drug solution is completed, the needle 21 is withdrawn from the fold 5, and then the clamp arms 31 are separated from each other and detached from the skin;

[0047] During the injection of the liquid medicine, the liquid medicine causes the folds 5 to expand and squeeze the sensing element 41, causing the sensing element 41 to generate a signal. If the change value of the signal reaches or exceeds the set threshold, the detection result is a successful injection; otherwise, the injection is unsuccessful.

[0048] It should be noted that if Fig.13 As shown, 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 arm 31 pinches the skin of the poultry to be injected to form a raised wrinkle 5, and the height of the raised skin is basically consistent with the space of the clamping area 311, and the needle insertion position is opposite to the wrinkle 5. Since the two clamping arms 31 are provided with protrusions 312, when the protrusions are pinched, an isolation area 35 for isolating the protrusions and muscles is formed between the protrusions 312. At this time, the raised part, i.e., the wrinkle 5, is all subcutaneous tissue; the setting of the protrusion 312 and the isolation area 35 can effectively physically isolate the subcutaneous tissue from the muscle or cervical vertebra, and completely avoid the risk of the needle 21 entering the muscle or cervical vertebra, thereby improving the accuracy and stability of injection.

[0049] The isolation area 35 is not directly formed by the protrusions 312, but is formed by the skin when the skin is squeezed by the protrusions 312 when the protrusions 312 clamp the skin;

[0050] In this method, the skin is clamped by the clamp arm 31, so that the poultry skin forms raised wrinkles 5 and is clamped in the clamping area 311 of the clamp arm 31. Since the wrinkles 5 are basically subcutaneous tissue, the subcutaneous tissue, muscle or spine can be effectively physically isolated by the clamping of the clamp arm 31. At this time, the needle 21 of the syringe 2 enters the clamping area 311 to effectively ensure that the needle 21 is inserted into the subcutaneous tissue, thereby improving the accuracy of the injection site and the injection stability.

[0051] At the same time, when the injection position of the needle 21 is correct, the skin in the clamping area 311 will expand and squeeze the sensing element 41, thereby causing the sensing element 41 to produce a signal change. Compared with manually plucking the feathers to check the color change of the injection position, the automatic detection setting of the sensing element 41 can effectively improve the automation and efficiency of the detection of the poultry injection situation; and the injection of the needle 21 and the detection of the sensing element 41 both act on each poultry, so the method will perform injection detection on each poultry that needs to be vaccinated, thereby greatly improving the accuracy and comprehensiveness of vaccine injection detection, and at the same time effectively reducing the cost of manual detection.

[0052] Specifically, in the present method, a classification scheme for poultry with unsuccessful injection is also proposed. A transmission mechanism 6 for batch conveying of poultry may be provided on one side of the frame 1, and a feeding basket 61 may be provided on the other side of the transmission mechanism 6. A plurality of fixed positions 62 are fixed on the transmission mechanism 6. When in use, the poultry is fixed on the fixed position 62, and under the transmission action of the transmission mechanism 6, the poultry is moved to the frame 1 for vaccine injection and detection. After the injection is completed and the detection is successful, the frame 1 retreats, and the poultry on the fixed position 62 is conveyed by the transmission mechanism 6 and moved to the feeding basket 61 to release the poultry, thereby achieving the purpose of vaccine injection, automatic detection and automatic feeding.

[0053] Furthermore, a storage basket 63 may be provided below the rack 1, and a rejection cylinder (not shown) is provided on the fixed position 62. When the injection of the rack 1 is completed, the sensor 41 does not generate a signal change, indicating that no poultry is placed on the fixed position or the injection of the liquid medicine is not accurately injected into the subcutaneous tissue of the poultry. At this time, the rejection cylinder is started and the poultry in the fixed position 62 is pushed out to fall into the storage basket 63, thereby achieving effective classification of the poultry with successful injection and the poultry with unsuccessful injection, which greatly reduces the manual screening cost;

[0054] By setting up the rejection cylinder, the feed basket 61 and the storage basket 63, the poultry with successful injection and the poultry with unsuccessful injection can be effectively classified. If manual review is required, it is only necessary to sample and review the poultry in the feed basket 61, which effectively improves the convenience of vaccine injection review.

[0055] Specifically, in order to increase the service life of the sensing element 41 and save energy, during the injection of liquid medicine, the sensing element 41 is activated when the liquid medicine is injected into the folds 5; when the injection stops, the sensing element 41 stops synchronously; since the method is mainly to detect the expansion change caused when the liquid medicine enters the subcutaneous tissue to identify the injection result, the activation time of the sensing element 41 is set during the skin expansion process, and the sensing element 41 stops working in other steps, thereby saving resources and effectively increasing the service life of the sensing element 41;

[0056] Furthermore, when the clamp arm 31 clamps the skin to form a raised wrinkle 5, an inclined angle B is formed between the wrinkle bottom 52 and the horizontal plane. In order to improve the comfort of the contact between the wrinkle bottom 52 and the sensing element 41 and the accuracy of detection, the sensing surface 411 is designed to be inclined, and the inclination angle of the sensing surface 411 is adapted to the inclination angle of the wrinkle bottom 52.

[0057] Furthermore, the sensing element 41 is a pressure sensor. The present detection method mainly determines whether the injection site is correct and whether the vaccine injection is successful by detecting whether the subcutaneous tissue expands during the injection process and forms pressure on the sensing element 41. The detection of the pressure change can effectively improve the detection accuracy and the accuracy of the detection results.

[0058] Specifically, Fig. 9 As shown, the clamp arm 31 includes a longitudinal arm 32 and a transverse arm 33, one end of the transverse arm 33 is fixedly connected to the top of the longitudinal arm 32, and the other end is rotatably connected to the frame 1; the two opposite surfaces of the two transverse arms 33 are provided with symmetrically arranged arc-shaped inner concave surfaces 331, and the two inner concave surfaces 331 form a through hole 34, and the syringe 2 is penetrated in the through hole 34; by providing the inner concave surface 331 with a avoiding effect, the occupied space of the syringe 2 and the clamping mechanism 3 can be effectively increased, making the device more compact and improving the space utilization rate;

[0059] Furthermore, if Figure 10-11 As shown, in this method, the lifting and lowering movement of the syringe 2 and the clamping movement of the clamping mechanism 3 are linked, that is, only the lifting and lowering of the syringe 2 is driven, and the clamping mechanism 3 will automatically link and cooperate with the syringe 2;

[0060] The peripheral wall of the syringe 2 is provided with a conical surface 22 abutting against the through hole 34, and the conical surface 22 includes an upper portion 221 and a lower portion 222 arranged in a vertical direction, and the outer wall diameter D1 of the lower portion 222 is larger than the outer wall diameter D2 of the upper portion 221;

[0061] When the syringe 2 drives the needle 21 to move toward the clamping area 311, the conical surface 22 moves downward relative to the through hole 34. At this time, the diameter of the conical surface 22 that abuts against the through hole 34 gradually decreases, and the clamping arms 31 will also clamp together and move closer. When the inner wall of the through hole 34 abuts against the outer wall of the upper part 221, the clamping arms 31 are just in a mutually closed clamping state; when the syringe 2 moves upward, so that the inner wall of the through hole 34 abuts against the outer wall of the lower part 222, since the diameter of the lower part 222 is larger than the diameter of the upper part 221, the clamping arms 31 are pushed to form an open state away from each other;

[0062] Through the design of the through hole 34 and the tapered surface 22, the clamping arm 31 can automatically move in conjunction with the lifting and lowering of the syringe 2, so that the clamping mechanism 3 and the syringe 2 can be automatically matched, and the matching error is small, thereby improving the injection efficiency and the detection efficiency;

[0063] It should be noted that, in another embodiment, the syringe 2 and the clamping mechanism 3 may adopt independent driving mechanisms (not shown), and then adopt circuit control to drive the linkage operation of the two; compared with this linkage structure, the connection structure in this embodiment has lower cost and smaller linkage error;

[0064] Furthermore, if Fig. 9 As shown, in order to make the inner wall of the through hole 34, i.e., the inner concave surface 331, always fit the conical surface 22, a first elastic member 321 is provided between the two longitudinal arms 32, one end of the first elastic member 321 is fixedly connected to the longitudinal arm 32, and the other end is fixedly connected to the other longitudinal arm 32. The function of the first elastic member 321 is mainly to make the two clamping arms 31 tend to maintain the clamping state, so as to achieve the purpose of the inner wall of the through hole 34 always fitting the conical surface 22.

[0065] Specifically, Fig.12 As shown, a connecting hole 11 is provided in the frame 1, and the syringe 2 is slidably connected in the connecting hole 11. A first step 23 is provided on the peripheral wall of the syringe 2. A second step 12 is fixedly provided in the connecting hole 11 and below the first step 23. A second elastic member 13 is elastically pressed between the first step 23 and the second step 12. Through the arrangement of the first step 23, the second step 12 and the second elastic member 13, the syringe 2 has a reset function of moving upward, so that the syringe 2 is moved downward for injection under the action of the driving mechanism. After the injection is completed, the syringe 2 can automatically reset under the elastic force of the second elastic member 13, so that the movement of the syringe 2 is more automated, and the consumer's use experience is better;

[0066] Furthermore, in the connecting hole 11, at least one sealing ring 24 is fixedly provided on the peripheral wall of the syringe 2; through the setting of the sealing ring 24, the syringe 2 is fully fitted with the inner wall of the connecting hole 11, and a deceleration damping effect is formed for the movement of the syringe 2, so as to reduce the sliding friction between the syringe 2 and the frame 1, thereby improving the service life of the syringe 2.

[0067] Specifically, Figure 4 As shown, in this embodiment, the detection mechanism 4 further includes a long strip-shaped fixing rod 42, one end of which is fixedly connected to the frame 1, and the other end of which extends toward the clamping area 311 of the clamping arm 31 and is fixedly connected to the sensing member 41; since the sensing member 41 requires independent circuit control, the sensing member 41 does not need to rotate with the clamping arm 31, so providing an independent fixing rod 42 to fix the sensing member 41 can keep the sensing member 41 on one side of the clamping area 311 of the clamping arm 31 in the clamping state, thereby ensuring accurate measurement of each injection, so as to improve the detection accuracy and injection efficiency;

[0068] At the same time, since the position setting of the sensing part 41 is matched with the clamping area 311, when the difference in the positions of the two causes incorrect detection results, it is only necessary to replace the appropriate fixing rod 42 to achieve the position adaptation of the sensing part 41 and the clamping area 311. The replacement process is simple and convenient, thereby improving the position adjustment efficiency of the sensing part 41 and the clamping area 311.

[0069] The working principle of the present invention is described in detail below;

[0070] When in use, the frame 1 first moves to the neck of the poultry, and then drives the syringe 2 through the driving mechanism to drive the needle 21 to move downward. During the downward movement, due to the structure of the conical surface 22, the clamping mechanism 3 performs linkage clamping to achieve clamping of the skin and form raised wrinkles 5. At this time, more subcutaneous tissue is located in the clamping area 311 and plays a role in physically separating the subcutaneous tissue and muscles or spine;

[0071] The needle 21 is located in the fold 5 and during the injection process, the liquid medicine causes the fold 5 to expand and squeeze the sensing element 41, causing the sensing element 41 to generate a signal. If the change value of the signal reaches or exceeds the set threshold, the detection result is that the injection is successful; otherwise, the injection is unsuccessful.

[0072] After the injection is completed, the needle 21 moves upward and resets under the elastic force of the second elastic member 13, and the clamping mechanism 3 also moves in conjunction with the syringe 2 to an open state and detaches from the skin.

[0073] The innovation of the present invention is that a pressure sensor is arranged below the clamping area, and a clamping mechanism is used to clamp the skin to form raised wrinkles, so that the bottom of the wrinkles is kept in contact with the pressure sensor, thereby effectively improving the detection accuracy of the pressure sensor;

[0074] At the same time, by detecting the pressure changes of the pressure sensor during the injection process to determine whether the injection is successful, it can not only effectively improve the timeliness of the detection to obtain the test results faster, but also further improve the detection accuracy and comprehensiveness of the detection.

[0075] 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.

[0076] 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. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
