Description

Technical Field

[0001] This invention relates to the field of medical analysis device technology, specifically to an animal medical sample analysis device. Background Technology

[0002] Animal medical sample analysis devices are automated or semi-automated instruments designed specifically for pets, livestock, and laboratory animals. They are used for testing samples such as blood, urine, feces, body fluids, and nucleic acids. The core features are speed, accuracy, and animal-specific design. They support disease diagnosis, treatment monitoring, and health management, and are one of the most common medical analysis devices.

[0003] Traditional animal medical sample analysis devices cannot automatically remove and clean the residual samples after testing. The samples need to be manually removed and cleaned separately, which greatly increases the workload of sampling, removal, cleaning and repositioning, reduces the testing efficiency, and the samples are mostly medical waste such as animal blood, body fluids and secretions. During the manual removal process, leakage and splashing are likely to occur, increasing the risk of biological contamination and cross-infection.

[0004] To address the aforementioned issues, we propose an animal medical sample analysis device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an animal medical sample analysis device that enables automatic cleaning after testing. This eliminates the need for manual removal of samples for separate cleaning, reducing manual workload, simplifying the operation process, and improving testing efficiency. The automatic cleaning device also avoids manual contact with the tested animal medical samples, reducing the risk of sample leakage, splashing, and biological contamination, minimizing the risk of cross-infection, and enhancing safety in use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an animal medical sample analysis device, comprising a body, a sealing cover rotatably mounted on the left side of the top of the body, a plate-type optical transmission detector disposed on the rear side of the inner wall of the body, and a perforated fixing plate fixedly mounted on both the upper and lower sides of the inner wall of the body located on the plate-type optical transmission detector, and a detection tube being provided on the multiple inner walls of the upper and lower perforated fixing plates.

[0007] The lower side of the inner wall of the detection tube is provided with an annular sludge trough, and L-shaped sludge outlets are provided on both opposite sides of the inner wall of the annular sludge trough. A conical liquid inlet is provided at the center of the bottom of the detection tube, and L-shaped air intakes are provided on both opposite sides of the inner wall of the conical liquid inlet.

[0008] The lower side of the inner wall of the detection tube is provided with a spraying component around the conical inlet. The inner wall of the detection tube is slidably installed with movable blocks on one side of the two L-shaped sewage outlets. The inner wall of the L-shaped sewage outlet is close to the movable blocks. A storage tank is opened on the side of the L-shaped sewage outlet close to the movable blocks. A sealing plate is movably installed on the inner wall of the storage tank. Two pull plates are rotatably installed on the side of the sealing plate close to the conical inlet. A connecting port for connecting to the conical inlet is opened on the inner wall of the storage tank on one side of the two pull plates.

[0009] Furthermore, a pull handle is fixedly installed on the front of the sealing cover, the bottom of the sealing cover is engaged with the top of the machine body, and a sealing ring is fixedly provided on the periphery of the bottom of the sealing cover, which seals against the periphery of the inner wall of the machine body.

[0010] Furthermore, the front of the machine body is provided with an observation glass window for observation, and rubber support columns are fixedly installed at the four corners of the bottom of the machine body.

[0011] Furthermore, all of the aforementioned detection tubes are integrally molded from transparent glass, and the detection tubes are simultaneously inserted into the corresponding snap-fit ​​holes of two porous fixing plates.

[0012] Furthermore, the conical liquid inlet has a structure with a straight cylindrical upper section and a flared lower section, and the flared section is set with a larger bottom and a smaller top. The projections of the axes of the two L-shaped air intakes and the axes of the two L-shaped waste outlets on the horizontal plane are perpendicular to each other.

[0013] Furthermore, a check valve is fixedly installed on the lower side of the inner wall of the L-shaped air intake, and a conical accelerator is fixedly installed on the inner wall of the L-shaped air intake near the conical liquid inlet, with the small end of the conical accelerator facing the conical liquid inlet. The conical accelerator can accelerate the gas flowing into the conical liquid inlet, thereby ensuring better mixing of the gas and liquid. This ensures that during cleaning, the bursting of bubbles better cleans the detection tube, increasing the cleaning quality, while the check valve can better prevent liquid leakage caused by backflow of gas and liquid.

[0014] Furthermore, the spraying assembly includes a spraying multi-hole vertical pipe with the detection tube fixedly installed around it, and the top of the spraying multi-hole vertical pipe is set with an arc-shaped head. A sealing spring is fixedly installed on the upper side of the inner wall of the spraying multi-hole vertical pipe, and a sealing multi-hole vertical pipe is fixedly installed at the lower end of the sealing spring.

[0015] The sealing multi-hole vertical tube is movably sleeved inside the spraying multi-hole vertical tube, and the positions of their holes correspond. The sealing spring is made of ceramic material. Under normal conditions, under the elastic force of the sealing spring, the holes of the sealing multi-hole vertical tube and the holes of the spraying multi-hole vertical tube are offset from each other. Under the action of external force, the sealing multi-hole vertical tube moves vertically inside the spraying multi-hole vertical tube, so that the holes of the two gradually align to achieve spraying.

[0016] Furthermore, the movable baffle is an arc-shaped plate structure with an arc-shaped guide surface protruding downward on its inner wall. When water flows through, the movable baffle is displaced under the action of the water flow.

[0017] Furthermore, the width of the sealing plate is adapted to the width of the L-shaped drain outlet, ensuring that the L-shaped drain outlet is sealed when the sealing plate is closed. The upper part of the pull plate extends to the inner wall of the conical liquid inlet through the connecting port, and the upper part of the pull plate is rotatably connected to the surface of the movable stop. The bottom of the pull plate and the lower side of the inner wall of the storage tank are fixedly installed with a tension spring, and the tension spring extends into the storage tank through the connecting port.

[0018] Furthermore, the top of the detection tube is provided with an arc-shaped protrusion that can contact the upper porous fixing plate, and a limiting rubber ring is fixedly installed on the lower surface of the detection tube, with the bottom of the limiting rubber ring contacting the top of the lower porous fixing plate.

[0019] A connecting pipe rack is provided at the bottom of multiple detection tubes, and a drain pipe is fixedly installed on one side of the inner wall of the machine body. The connecting pipe rack is a frame composed of several pipes and can correspond to the lower part of multiple detection tubes. A conical connecting pipe is fixedly installed at the top of the connecting pipe rack directly below the conical liquid inlet. The conical connecting pipe is adapted to the conical liquid inlet. The connecting pipe rack is fixedly installed to the inner wall of the machine body. The rear ends of the connecting pipe rack and the drain pipe both extend through to the rear of the machine body, and a connecting valve head is fixedly installed at the rear ends of the connecting pipe rack and the drain pipe.

[0021] 1. This device enables automatic cleaning after testing, eliminating the need for manual removal of samples for separate cleaning. This reduces manual workload, simplifies the operation process, and improves testing efficiency.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1 to 13 An animal medical sample analysis device in this embodiment includes a body 1, a sealing cover 2 rotatably mounted on the left side of the top of the body 1, an observation glass window 101 for observation at the front of the body 1, and rubber support columns 102 fixedly mounted at the four corners of the bottom of the body 1. A pull handle 201 is fixedly mounted on the front of the sealing cover 2, the bottom of the sealing cover 2 is engaged with the top of the body 1, and a sealing ring 202 is fixedly mounted on the periphery of the bottom of the sealing cover 2.

[0042] The sealing ring 202 is sealed to the inner wall of the body 1. A plate-type optical transmission detector 3 is provided on the rear side of the inner wall of the body 1. A multi-hole fixing plate 4 is fixedly installed on both the upper and lower sides of the inner wall of the body 1 located on the plate-type optical transmission detector 3. Multiple inner walls of the upper and lower multi-hole fixing plates 4 are provided with detection tubes 5. The multiple detection tubes 5 are made of light-transmitting glass in one piece. The detection tubes 5 are simultaneously inserted into the corresponding snap-fit ​​holes of the two multi-hole fixing plates 4.

[0043] The detection tube 5 has an annular sludge trough 6 on the lower side of its inner wall, and L-shaped sludge outlets 7 on opposite sides of the inner wall of the annular sludge trough 6. A conical liquid inlet 8 is located at the center of the bottom of the detection tube 5. L-shaped air inlets 9 are located on opposite sides of the inner wall of the conical liquid inlet 8. The conical liquid inlet 8 has a structure with a straight cylindrical upper section and a flared lower section, with the flared section being larger at the bottom and smaller at the top. The projections of the axes of the two L-shaped air inlets 9 and the axes of the two L-shaped sludge outlets 7 onto the horizontal plane are perpendicular to each other. A check valve 901 is fixedly installed on the lower side of the inner wall of the L-shaped air inlet 9. A conical accelerator 902 is fixedly installed on the inner wall of the L-shaped air inlet 9 near the conical liquid inlet 8, with the small end of the conical accelerator 902 facing the conical liquid inlet 8.

[0044] A spraying assembly 10 is provided on the lower side of the inner wall of the detection tube 5 around the conical liquid inlet 8. Movable blocks 11 are slidably installed on one side of the two L-shaped sewage outlets 7 on the inner wall of the detection tube 5. A storage tank 12 is provided on the side of the L-shaped sewage outlet 7 near the movable blocks 11. A sealing plate 13 is movably installed on the inner wall of the storage tank 12. Two pull plates 14 are rotatably installed on the side of the sealing plate 13 near the conical liquid inlet 8. A connecting port 15 for connecting to the conical liquid inlet 8 is provided on the side of the inner wall of the storage tank 12 near the two pull plates 14.

[0045] The movable baffle 11 is an arc-shaped plate structure with an arc-shaped guide surface protruding downward on its inner wall. When water flows through, the movable baffle 11 is displaced under the action of the water flow.

[0046] The spraying assembly 10 includes a spraying multi-hole vertical pipe 1001 with the detection tube 5 fixedly installed around it. The top of the spraying multi-hole vertical pipe 1001 is set with an arc head. A sealing spring 1002 is fixedly installed on the upper side of the inner wall of the spraying multi-hole vertical pipe 1001, and a sealing multi-hole vertical pipe 1003 is fixedly installed at the lower end of the sealing spring 1002.

[0047] The sealing multi-hole vertical pipe 1003 is movably sleeved inside the liquid spraying multi-hole vertical pipe 1001, and the positions of the holes of the two are corresponding. The sealing spring 1002 is made of ceramic material. Under normal conditions, under the elastic force of the sealing spring 1002, the holes of the sealing multi-hole vertical pipe 1003 and the holes of the liquid spraying multi-hole vertical pipe 1001 are misaligned. Under the action of external force, the sealing multi-hole vertical pipe 1003 moves vertically inside the liquid spraying multi-hole vertical pipe 1001, so that the holes of the two are gradually aligned to achieve liquid spraying.

[0048] The width of the sealing plate 13 is adapted to the width of the L-shaped drain outlet 7, which can ensure that the L-shaped drain outlet 7 is closed when the sealing plate 13 is closed. The upper part of the pull plate 14 extends to the inner wall of the conical liquid inlet 8 through the connecting port 15, and the upper part of the pull plate 14 is rotatably connected to the surface of the movable stop block 11. The bottom of the pull plate 14 and the lower side of the inner wall of the storage tank 12 are fixedly installed with a tension spring 20, and the tension spring 20 extends into the storage tank 12 through the connecting port 15.

[0049] The top of the detection tube 5 is provided with an arc-shaped protrusion that can contact the upper porous fixing plate 4, while a limiting rubber ring 501 is fixedly installed on the lower surface of the detection tube 5, and the bottom of the limiting rubber ring 501 contacts the top of the lower porous fixing plate 4.

[0050] A connecting pipe rack 16 is provided at the bottom of multiple detection tubes 5, and a drain pipe 17 is fixedly installed on one side of the inner wall of the machine body 1. The connecting pipe rack 16 is a frame composed of several pipes and can correspond to the lower part of multiple detection tubes 5. A conical connecting pipe 18 is fixedly installed at the top of the connecting pipe rack 16 directly below the conical liquid inlet 8. The conical connecting pipe 18 is adapted to the conical liquid inlet 8. The connecting pipe rack 16 is fixedly installed on the inner wall of the machine body 1. The rear ends of the connecting pipe rack 16 and the drain pipe 17 extend through to the rear of the machine body 1. A connecting valve head 19 is fixedly installed at the rear ends of the connecting pipe rack 16 and the drain pipe 17.

[0051] The working principle of the above embodiments is as follows:

[0052] Before the device is used, under the elastic force of the sealing spring 1002, the holes of the sealing multi-hole vertical pipe 1003 and the holes of the spraying multi-hole vertical pipe 1001 are offset from each other, and the spraying assembly 10 is in the closed state. At the same time, the movable stop block 11 is in the low position under the action of the weight and the tension spring 20. The sealing insert plate 13 is moved into the storage tank 12 by the pull plate 14, and the L-shaped sewage outlet 7 is in the closed state. In this way, when the detection tube 5 is placed inside the porous fixing plate 4 after sampling, the sample will not leak.

[0053] When the sample enters, the plate-type optical transmission detector 3 will be used to detect the sample in the detection tube 5, thereby completing the basic sample analysis. Because the plate-type optical transmission detector 3 has the function of using intelligent sensors and is a mature technology, it can ensure the accuracy and efficiency of the detection.

[0054] After the test is completed, cleaning liquid is delivered into the machine body 1 through the connecting tube rack 16. The flared opening of the conical liquid inlet 8 has the effect of guiding the flow. At the same time, the sample flows at the position of the movable baffle 11. Due to the volume of the baffle, a negative pressure is generated at this position, which in turn generates a suction effect using the L-shaped air inlet 9. The fluid filled with gas will increase the generation of bubbles. When the liquid with bubbles is rinsed, the bursting of the bubbles can generate a bursting impact, which can better clean the inner wall of the test tube 5.

[0055] As the liquid is continuously injected, it will exert an upward thrust on the sealing porous riser 1003. This thrust overcomes the elastic force of the sealing spring 1002, causing the sealing porous riser 1003 to move upward within the spray porous riser 1001. The holes of the two gradually change from a misaligned state to an aligned state. The spray assembly 10 is turned on, and the cleaning liquid is evenly sprayed onto the inner wall of the detection tube 5 through the aligned holes, ensuring full coverage of the detection tube 5 and thus achieving a full tilting effect.

[0056] During the cleaning process, the arc-shaped guide surface of the movable baffle 11 is subjected to an upward component force, which causes the movable baffle 11 to move upward. When the movable baffle 11 moves upward, the sealing plate 13 moves away from the L-shaped drain outlet 7 through the pull plate 14 connected to it. During the movement, the pull plate 14 stretches the tension spring 20. When the movable baffle 11 rises to the set position, the sealing plate 13 opens the L-shaped drain outlet 7. This ensures that the cleaning liquid falls through the L-shaped drain outlet 7 and is discharged outside the machine body 1 through the drain pipe 17. In use, the connecting pipe rack 16 and the drain pipe 17 are connected to the liquid conveying device and the sewage collection device in advance. This connection method is a mature existing technology and will not be described in detail in this application.

[0057] After cleaning, the cleaning liquid injection will stop. As the liquid level drops, the impact force of the sample on the movable stop 11 disappears. Under the reset pulling force of the tension spring 20, the pull plate 14 swings in the opposite direction and pushes the sealing insert 13 into the L-shaped sewage outlet 7 to close it. At the same time, the sealing multi-hole vertical pipe 1003 resets and moves downward under the elastic force of the sealing spring 1002. Its holes are misaligned with the holes of the spray multi-hole vertical pipe 1001 again, and the spray assembly 10 is closed.

[0058] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
