Description

Technical Field

[0001] This invention belongs to the field of plague monitoring technology, and specifically relates to an intelligent rapid detection device for rat trapping based on plague monitoring. Background Technology

[0002] Plague is a highly contagious disease caused by *Yersinia pestis*, classified as a Class A infectious disease in my country. It is characterized by rapid onset, rapid progression, and high mortality, and has historically caused several global pandemics. Although human cases of plague have been relatively few in recent years, the disease persists in wild animals (especially rodents), posing a serious potential public health threat. *Yersinia pestis* is listed in the high-risk category (Category II) of the *Catalogue of Human Infectious Pathogens* (2023 edition), and sample testing must be performed in a Biosafety Level 2 (BSL-2) or Biosafety Level 3 (BSL-3) laboratory. Routine laboratory methods mainly include bacterial culture and staining microscopy, PCR nucleic acid detection, ELISA, or indirect immunofluorescence assays, etc., with complex testing procedures. These procedures require the participation of professional personnel, and the transportation time from rodent capture to the laboratory is lengthy, resulting in long laboratory testing cycles and high exposure risks.

[0003] Currently, plague surveillance faces the following challenges: 1. Rodents are active, and plague foci exhibit a periodic "active-quiet" state, requiring continuous monitoring; 2. Most plague outbreaks are only discovered after human cases appear, lacking a proactive early warning mechanism; 3. Traditional rodent trapping and pathogen detection in surveillance present technical hurdles and timeliness bottlenecks for disease prevention and control in grassroots and remote areas. Summary of the Invention

[0004] To address the shortcomings of the prior art, this invention provides an intelligent rapid detection device for rodent trapping based on plague monitoring.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A smart rat-catching rapid detection device based on plague monitoring includes a cage body, a cage door, a pressure bar, and a bait hook. The cage body has a cage door at its opening, and a pressure bar is installed on the cage door. When the pressure bar is in a horizontal state, its end is connected to the bait hook located at the rear end of the cage body. The device also includes a rapid blood collection device and a reset and slapping device. The rapid blood collection device is fixedly installed on the side of the rear end of the cage body, and the reset and slapping device is installed inside the cage body to slap and press the rat against the rapid blood collection device. The reset and slapping device is located inside the cage body and on the same side as the rapid blood collection device.

[0007] The innovation of this invention is to add a rapid blood collection device and a resetting and slapping device to the existing rat traps. After the rats are caught, they can be driven and slapped onto the rapid blood collection device, and then blood can be collected from the rats to test whether they are infected with plague.

[0008] Furthermore, the rapid blood collection device includes a mounting plate, a rapid test strip for Yersinia pestis, a blood collection needle, and a protective film cover. The mounting plate is detachably mounted on the outer rear side of the cage. Several rapid test strips for Yersinia pestis facing outward are mounted on the mounting plate in a random or irregular manner. Each test strip has a blood collection needle facing inward, and the blood collection needle has a protective film cover. The rapid blood collection device uses LFA chromatography test strips.

[0009] Furthermore, the length of the blood collection needle is 1.0~2.0cm and the diameter of the blood collection needle is 0.1mm, ensuring the length and hardness of the blood collection needle to facilitate insertion into the mouse for blood collection.

[0010] Furthermore, the reset tapping device includes a fixed shaft, a torsion spring, a tapping plate, a pull rope, a placement seat, a cylindrical tube, and a groove. The fixed shaft is fixedly installed on the right side of the rapid blood collection device, and the tapping plate is rotatably installed on the fixed shaft via the torsion spring. In its initial state, the tapping plate is pressed into contact with the rapid blood collection device by the torsion spring. The placement seat is installed on the top of the cage and below the pressure rod in its horizontal state. One end of the pull rope is fixedly connected to the front end of the tapping plate, and the other end of the pull rope is fixedly connected to the end of the cylindrical tube. After the tapping plate is horizontally flipped, the cylindrical tube can be placed on the placement seat. The placement seat and the cylindrical tube are provided with grooves for engaging and positioning with the pressure rod. The function of the reset tapping device is to tap and press the rat onto the rapid blood collection device for blood collection and testing at the moment the rat trap is closed.

[0011] Furthermore, the height of the clapper is 1.0 to 2.0 cm smaller than the height of the cage, and the length of the clapper is 0.5 cm smaller than the width of the cage. In the initial state, the front end of the clapper is 0.5 cm away from the bottom of the cage, ensuring that the clapper covers the range of motion of the mouse at the rear of the cage, and can knock the mouse to the appropriate position.

[0012] Furthermore, it also includes a connecting part and a monitoring device. The monitoring device is detachably installed on the rapid blood collection device via the connecting part. The rapid blood collection device and the monitoring device are arranged at intervals relative to each other. Under the action of the connecting part, the monitoring device can serve as a loading component. The installation of the monitoring device is suitable for use in the field.

[0013] Furthermore, the connecting part is a rectangular transparent connecting cover, which facilitates installation and allows the test results of the test paper box to be observed from the outside.

[0014] Furthermore, the monitoring device includes a monitoring body and a camera. The camera is installed on the surface of the monitoring body opposite to the rapid blood collection device, and the camera is used to monitor changes in the test strip box.

[0015] Furthermore, the monitoring unit is equipped with a control board, wireless communication module, positioning module, antenna, battery, alarm system, vibration sensor and indicator light, which can intelligently and remotely monitor the test kit, and the monitoring data can be transmitted back to the epidemic prevention and monitoring center in real time.

[0016] Furthermore, it also includes a solar panel, which is installed on top of the monitoring device and can extend the operating time of the monitoring device when used in the field, ensuring that the monitoring unit is protected from power failure.

[0017] The advantages of this invention are as follows: 1. This invention is designed as an integrated, field-usable, easy-to-operate, and intelligently alarm-equipped automatic rapid plague detection device for the wild, enabling rapid screening and early warning of wild rodent infection status; 2. This invention integrates rodent trapping, blood collection, and rapid detection into a single device, avoiding exposure during live rodent transportation and on-site operations, and reducing the burden on grassroots personnel; 3. This device uses disposable test strips, an automatic blood collection device, and image recognition technology to determine whether a result is positive within 15 minutes and can notify monitoring personnel in real time; 4. This invention features a modular design, with the rapid blood collection device, reset and tapping device, and monitoring device operating independently. Damage can be replaced individually, and it can be modified for most existing rodent traps on the market, making it highly adaptable. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings:

[0025] In the description of this invention, it should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in when in use. It is only for the convenience of describing this invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, it should not be construed as a limitation of this invention.

[0026] A smart rat trapping and rapid detection device based on plague monitoring includes a stainless steel mesh cage body 1, a cage door 2, a pressure bar 3, a bait hook 4, a rapid blood collection device 5, a reset and tapping device 6, a connecting part 7, a monitoring device 8, and a solar panel 9. The cage body 1 has a cage door 2 installed at the cage opening using a torsion spring or elastic structure. The cage door 2 has a pressure bar 3 installed on it. When the pressure bar 3 is in a horizontal state, its end is connected to the bait hook 4 located at the rear end of the cage body 1. The structure of the entire rat trap is the same as that of existing rat traps. When a rat enters the rat trap and pulls on the bait hook 4, the pressure bar 3 is released, and the cage door 2 closes.

[0027] like Figure 1-2 As shown, a rapid blood collection device 5 is fixedly installed on the side of the rear end of the cage 1. The rapid blood collection device 5 is used to collect blood samples from rats after they enter the cage for testing. Inside the cage 1, there is a reset tapping device 6 that knocks the rat onto the rapid blood collection device 5. The reset tapping device 6 is located inside the cage 1 and on the same side as the rapid blood collection device 5. When a rat enters the cage and triggers a mechanism, the reset tapping device 6 will drive the rat onto the rapid blood collection device 5. A monitoring device 8 is detachably installed on the rapid blood collection device 5 via a rectangular transparent connecting part 7. The rapid blood collection device 5 and the monitoring device 8 are arranged at intervals opposite to each other. A solar panel 9 is installed on top of the monitoring device 8 to provide power for it in the field. The entire device adopts a waterproof design.

[0028] like Figure 3-4As shown, the rapid blood collection device 5 includes a mounting plate 51, a test strip box 52, a blood collection needle 53, and a thin film protective sleeve 54. The mounting plate 51 is detachably mounted on the outer rear end face of the cage 1. Several test strip boxes 52 are irregularly mounted on the mounting plate 51, facing outwards from the cage 1. This ensures that blood can be collected from any mouse, regardless of size, as long as it taps the rapid blood collection device 52. The outward-facing arrangement of the test strip boxes 52 facilitates observation of changes in the test strip boxes 52. The test strip box 52 uses a plague F1 antigen immunochromatographic test strip, and the test strip automatically starts reacting (color development within 10-15 minutes). The test strip box 52 is equipped with a blood collection needle 53 facing inwards from the cage 1. The blood collection needle 53 is 1.0~2.0cm long and 0.1mm in diameter, extending at least 0.5cm into the cage 1. This ensures that it can penetrate the mouse and collect enough blood without killing the mouse. The blood collection needle 53 is connected to the sample absorption hole of the test strip box 52. After the blood collection needle 53 is filled with absorbent cotton, the blood will quickly reach the test strip in the test strip box 52 along the absorbent cotton after the blood collection needle 53 is inserted into the mouse. A thin film protective sleeve 54 is provided on the blood collection needle 53. The function of the thin film protective sleeve 54 is to protect the blood collection needle 53 from being contaminated by the external environment.

[0029] like Figure 5As shown, the reset and tapping device 6 includes a fixed shaft 61, a torsion spring 62, a tapping plate 63, a pull rope 64, a placement seat 65, a cylindrical tube 66, and a groove 67. The fixed shaft 61 is fixedly installed on the right side of the rapid blood collection device 5, and the upper and lower ends of the fixed shaft 61 are fixedly connected to the upper and lower surfaces of the cage body 1 through the mounting seat. The tapping plate 63 is rotatably installed on the fixed shaft 61 through the torsion spring 62. In the initial state, the tapping plate 63 is pressed into contact with the rapid blood collection device 5 by the torsion spring 62, that is, after the tapping plate 63 is released, the mouse will be pressed onto the rapid blood collection device 5; the tapping plate 63 will only tap the mouse onto the rapid blood collection device 5 and will not kill the mouse. The placement seat 65 is installed on the top of the cage body 1 and is located below the pressure rod 3 in the horizontal state. The top surface of the placement seat 65 is on the same horizontal plane as the axis of the pressure rod 3. One end of the pull rope 64 is fixedly connected to the front end of the clapper 63, specifically at the middle of the front end of the clapper 63, and the other end of the pull rope 64 is fixedly connected to the end of the cylindrical tube 66. After the clapper 63 is horizontally flipped, the cylindrical tube 66 can be placed on the placement seat 65. The placement seat 65 is provided with a placement groove for limiting and placing the cylindrical tube 66. The height of the clapper 63 is 1.0~2.0cm smaller than the height of the cage 1, and the length of the clapper 63 is 0.5cm smaller than the width of the cage 1. In the initial state, the front end of the clapper 63 is 0.5cm away from the bottom of the cage 1. This ensures that the flipping range of the clapper 63 covers the entire range of the mouse's movement at the rear of the cage, ensuring that the mouse can be slapped onto the rapid blood collection device 5. The placement seat 65 and the cylindrical tube 66 are provided with grooves 67 for engaging and positioning with the pressure rod 3. The working principle of the reset tapping device 6 is as follows: when the tapping plate 63 is rotated 180 degrees, the torsion spring 62 will apply a force to make it have a flipping force; under the pull of the pull rope 64, the tapping plate 63 will remain in the flipped state, and the pull rope 64 will be locked by the placement seat 65 and the cylindrical tube 66 and the horizontal pressure rod 3. When the cage door 2 is closed, the pressure rod 3 will release the lock on the cylindrical tube 66, and then release the lock on the tapping plate 63. After the tapping plate 63 is unlocked, it will flip and tap on the rapid blood collection device 5 under the action of the torsion spring 62.

[0030] like Figure 6As shown, the monitoring device 8 includes a monitoring body 81 and a camera 82. The camera 82 is mounted on the surface of the monitoring body 81 opposite to the rapid blood collection device 5. The camera 82 can read changes in the test strips inside the test strip box 52, facilitating the triggering of an alarm sensor to a mobile phone or monitoring center terminal upon a positive detection. The monitoring body 81 contains a control board, a wireless communication module, an image recognition module, a positioning module, an antenna, a battery, an alarm system, a vibration sensor, indicator lights, and a temperature and humidity sensor. The control board provides comprehensive intelligent control of the monitoring device, managing the camera 82, which has both recognition and transmission functions, and uses an ESP32 or ESP8266 chip. The wireless communication module uses Bluetooth / LoRa to send alarms to the handheld terminal or central station. The image recognition module works with the camera 82 to read the T / C lines on the test strips. The positioning module is used to locate the device's position for easy inspection and data classification. The battery provides power to the monitoring device, using a 3.7V / 5V lithium battery and a USB charging interface. The alarm system is used to trigger an alarm upon detection of a rodent infestation. Once a test strip detects a positive result, an indicator light flashes, a buzzer sounds, and an SMS / alarm message is sent to a mobile app or monitoring workstation. Vibration sensors monitor the rodent trap's status; once the trap is closed, the vibration sensor detects the trap and, upon detecting a signal, the monitoring device 8 switches from a silent state to a monitoring state. Temperature and humidity sensors assist in recording environmental parameters.

[0031] Although the specific embodiments of the present invention have been described and illustrated in detail above, it should be noted that various changes and modifications can be made to the above embodiments without departing from the spirit of the present invention and the scope set forth in the appended claims.
