Description

Technical Field

[0001] The present invention relates to the technical field of mosquito-like blood-sampling drones, and in particular to a mosquito-like blood-sampling drone with an infrared blood vessel sensing function. Background Art

[0002] The mosquito-like blood-collecting drone, equipped with infrared blood vessel sensing, is an innovative drone that simulates the mosquito's blood-collecting process, enabling precise and painless blood collection from animals. Combining infrared sensing technology, a miniaturized puncture device, automated flight control, and an intelligent data analysis system, the drone mimics mosquito blood-sucking behavior, efficiently, painlessly, and accurately collecting blood from animals. It has widespread applications in medical research, animal health monitoring, and veterinary diagnosis.

[0003] When drawing blood from animals, existing technology makes it difficult to part the abundant hair on their bodies. This layer of hair increases puncture resistance, particularly when penetrating the skin, where it can hinder the needle's precise entry into the target vessel. In this case, the drone may require greater puncture force, which can increase discomfort for the animal or cause the needle to deviate from its target. Hair can also reduce the needle's stability, increase uncertainty during the puncture process, and lead to an uneven and uneven puncture, thus compromising blood collection effectiveness.

After combing the hair, the surface of the blood vessels is clearly visible, allowing the drone to find the location of the blood vessels more accurately, thereby improving the accuracy of blood collection. By combing the hair, the puncture needle can more smoothly contact the skin and accurately enter the blood vessel.

By setting up a transmission disinfection mechanism, while driving the spray tube to move to disinfect the blood collection point, it can also drive the hair combing mechanism to comb the hair. This can not only complete the disinfection of the blood collection point, but also drive the hair combing mechanism to comb the hair, reducing additional operation steps, ensuring that the disinfectant can directly contact the skin surface, avoiding hair obstruction, and improving the disinfection effect. It not only improves work efficiency, but also ensures the safety and painlessness of the operation; 3. By setting up a rotatable blood collection seat, it is possible to switch between multiple negative pressure blood collection needles. Different blood collection needles can be used for blood collection at the same time in the same operation, thereby improving the overall efficiency of blood collection, especially when different types of blood samples need to be collected. At the same time, by setting up an adjustment frame, the blood collection angle can be adjusted according to the blood collection site and animal body size to ensure accurate and comfortable blood collection.

DETAILED DESCRIPTION

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0019] like Figures 1-8 The mosquito-like blood-collecting drone with infrared blood vessel sensing function shown in the figure includes a drone body 1, and a plurality of support claws 8 are fixedly connected to the bottom edge of the drone body 1. The lower surface of the support claws 8 is fixedly provided with a hair sticking device 9. The support claws 8 play a role in improving the stability of flying and landing on the surface of the animal. The hair sticking device 9 can increase the friction when in contact with the fur surface, and play an anti-slip effect. The bottom of the drone body 1 is fixedly connected to a mounting frame 2, and an adjustment frame 3 is rotatably connected to the mounting frame 2. A fixed cover 4 is provided below the adjustment frame 3, and a blood collection seat 5 is rotatably provided in the fixed cover 4. A hair combing mechanism 6 is slidably provided on one side of the bottom end of the fixed cover 4, and a transmission disinfection mechanism 7 is slidably provided on the bottom end of the fixed cover 4.

[0020] like Figure 3 As shown, an electric push rod A201 is fixedly attached to the mounting frame 2, and an adjustment rack 202 is fixedly attached to the output end of the push rod A201. The adjustment rack 202 adjusts the angle of the adjustment frame 3. The push rod A201 drives the adjustment rack 202, which in turn drives the adjustment frame 3, which is connected to the adjustment wheel 301, to the desired angle. The fixed cover 4 is then moved by the push rod B302.

[0021] like Figure 4 As shown, an adjusting wheel 301 is fixedly connected to the adjusting frame 3, and the adjusting wheel 301 is meshed with the adjusting rack 202 for transmission. An electric push rod B302 is fixedly connected to the adjusting frame 3, and the other end of the electric push rod B302 is fixedly connected to the fixed cover 4.

[0022] like Figure 5 As shown, a removal port 401 is provided on one side of the fixed cover 4, and a stopper 402 is provided with a threaded connection to the removal port 401. An electric push rod C403 is fixedly provided on the other side of the fixed cover 4, and an extrusion plug 404 is fixedly provided on one end of the electric push rod C403 located inside the fixed cover 4. The stopper 402 facilitates the placement and removal of the negative pressure blood collection needle 502.

[0023] The bottom surface of the fixed cover 4 is symmetrically structured with two slots 405. A liquid reservoir 406 is defined on the inner wall of the bottom end of the fixed cover 4. A liquid filling tube 407 is fixedly connected to and extends through the liquid reservoir 406. A blood sampling port 408 is defined on one side of the bottom end of the fixed cover 4. An infrared sensor 409 is also fixedly mounted on the side of the bottom end of the fixed cover 4. Iodine is placed in the liquid reservoir 406. Infrared sensor 409 is a FLIR Lepton 3.5 model: it features high-resolution thermal imaging and is suitable for low-power, compact applications. It detects thermal radiation emitted by the human body, thereby identifying temperature differences in blood vessels and facilitating precise positioning.

[0024] like Figure 6 As shown, the blood collection seat 5 is annularly structured with multiple placement grooves 501, and a negative pressure blood collection needle 502 is placed in the placement groove 501. The top of the negative pressure blood collection needle 502 is in movable contact with the bottom surface of the extrusion plug 404. A motor 503 is fixedly connected to the inner wall of the middle part of the blood collection seat 5, and the motor 503 is fixedly connected to the inner wall of the fixed cover 4.

[0025] A needle holder 504 is slidably mounted within the placement slot 501. The needle holder 504 is adapted to accommodate the negative-pressure blood collection needle 502. A spring 505 is fixedly attached to each end of the needle holder 504, the other end of which is fixedly attached to the inner wall of the placement slot 501. The spring 505 automatically resets the negative-pressure blood collection needle 502. The motor 503 rotates the connected blood collection seat 5, aligning one of the negative-pressure blood collection needles 502 with the blood collection port 408. The electric push rod C403 then drives the connected squeeze plug 404 to move, squeezing the squeeze plug 404 to squeeze the negative-pressure blood collection needle 502, removing the negative-pressure blood collection needle 502 and inserting the needle into the animal's blood vessel.

[0026] like Figure 7As shown, the hair combing mechanism 6 includes two symmetrically arranged hair combs 601. A sliding frame 602 is rotatably connected to the hair combs 601. The top of the sliding frame 602 is slidably engaged with the inner wall of the slide groove 405. A beveled groove rod 603 is fixedly connected to one side of the sliding frame 602. A worm 604 is rotatably connected to one end of the sliding frame 602. A transmission wheel 605 is fixedly connected to one end of the worm 604. A fixed rack 606 is meshed and driven on one side of the transmission wheel 605. The fixed rack 606 is fixedly connected to the inner wall of the fixed cover 4. A worm gear 607 is fixedly connected to one end of the hair combs 601. The worm gear 607 meshes and drives with the worm 604. The worm 604 drives the hair combs 601 to rotate, thereby improving the combing effect. The hydraulic rod 702 is used to drive the connected slide 701 to move. At this time, the L-shaped transmission rod 703 on the slide 701 will slide in the inclined groove rod 603, thereby driving the slide frame 602 connected to the inclined groove rod 603 to move, so that the hair comb 601 at the bottom of the slide frame 602 combs the animal hair. Then, when the hair comb 601 engages with the fixed rack 606, it drives the worm 604 to rotate, so that the worm 604 drives the hair comb 601 connected to the worm gear 607 to rotate.

[0027] By arranging a hair combing mechanism 6 on the drone body 1, the hair at the blood collection site can be combed to both sides when blood is collected from an animal, which can effectively remove the hair at the blood collection site, so that the infrared sensor 409 simulates a mosquito and can more accurately sense the temperature difference of the blood vessels, which helps to locate the blood vessels and reduce the difficulty of locating the blood vessels due to hair obstruction. After combing the hair, the surface of the blood vessels is clearly visible, so that the drone body 1 can find the position of the blood vessels more accurately, thereby improving the accuracy of blood collection. By combing the hair, the puncture needle can contact the skin more smoothly and enter the blood vessel accurately. The pushing of the hair makes the needle penetration path smoother, avoiding the deviation of the needle or puncture failure caused by the resistance of the hair.

[0028] like Figure 8 Shown, transmission disinfection mechanism 7 comprises slide 701, slide 701 one end is fixedly connected with hydraulic rod 702, hydraulic rod 702 other end is fixedly connected with fixed cover 4 bottom inwall, slide 701 both sides are all fixedly connected with L-type transmission rod 703, L-type transmission rod 703 other end and chute rod 603 inwall sliding cooperation are provided with, slide 701 runs through and is fixedly connected with spray pipe 704, spray pipe 704 one end is fixedly connected with a plurality of shower nozzles 705, spray pipe 704 other end inwall sliding cooperation is provided with liquid guiding pipe 706, liquid guiding pipe 706 and liquid reservoir 406 inwall runs through and is fixedly connected to be provided with.One-way butterfly valve is all installed in spray pipe 704 and the liquid guiding pipe 706.When hydraulic rod 702 drives spray pipe 704 to reset, by liquid guiding pipe 706, the iodophor in liquid reservoir 406 can be sucked into spray pipe 704 and deposited.

[0029] Working Principle: When blood sampling is required, the drone 1 is first flown to a suitable location on the animal. The blood in the animal's body has different temperature characteristics from the surrounding tissue. The blood in the blood vessels is hotter than the surrounding tissue, which creates a clear temperature difference in the blood vessels in infrared imaging. This temperature difference information can be captured by the infrared sensor 409 to create an image of the blood vessels on the animal's skin surface, thereby locating the blood vessels. Then, the electric push rod A201 is used to drive the connected adjustment rack 202 to move, so that the adjustment rack 202 can drive the adjustment frame 3 connected to the adjustment wheel 301 to rotate to a suitable angle, and then the electric push rod B302 is used to drive the fixed cover 4 to move, so that the hair comb 601 contacts the animal's skin; Then, the hydraulic rod 702 is used to drive the connected slide 701 to move. At this time, the L-shaped transmission rod 703 on the slide 701 will slide in the inclined groove rod 603, thereby driving the slide frame 602 connected to the inclined groove rod 603 to move, so that the hair comb 601 at the bottom of the slide frame 602 combs the animal hair. Then, when the hair comb 601 engages with the fixed rack 606, it drives the worm 604 to rotate, so that the worm 604 drives the hair comb 601 connected to the worm gear 607 to rotate, and then continues to drive the fixed cover 4 to move, so that the hair comb 601 presses on the hair to keep the hair separated. Then, when the slide 701 moves, the liquid spraying tube 704 will be driven to move, and the iodine tincture in the liquid spraying tube 704 will be sprayed out through the nozzle 705 to disinfect the blood collection site; Then the motor 503 is used to drive the connected blood collection seat 5 to rotate, so that one of the negative pressure blood collection needles 502 is aligned with the blood collection port 408, and then the electric push rod C403 is used to drive the connected squeezing plug 404 to move, so that the squeezing plug 404 can squeeze the negative pressure blood collection needle 502, so that the negative pressure blood collection needle 502 is moved out and the needle tip is inserted into the animal's blood vessel, imitating mosquito blood collection. At this time, the negative pressure blood collection needle 502 attracts blood into the blood collection tube by controlling the negative pressure to collect the blood sample. When the squeezing plug 404 is reset, under the action of the spring 505, the negative pressure blood collection needle 502 on the needle and tube holder 504 will be driven to reset and retract, and then the cover 402 can be opened by rotating. At this time, the spring 505 will drive the negative pressure blood collection needle 502 to move up a part, thereby facilitating removal.
