Description

Technical Field

[0001] The invention relates to the technical field of vector control, and in particular to a mosquito larvae amplification and identification device. Background Art

[0002] The Breteau index method is one of the commonly used methods for monitoring dengue vector Aedes mosquitoes. Correct identification of mosquito larvae species is the key to accurate index calculation. Currently, the special box for monitoring Aedes mosquitoes commonly used at the grassroots level contains tools such as sample dishes, square plates, anemometers, flashlights, straws, chargers, scoops and colanders, but does not contain mosquito larvae observation tools. After capturing mosquito larvae, it is difficult to distinguish whether they are Aedes or Culex mosquitoes with the naked eye. They need to be taken back to the laboratory to feed them to adult mosquitoes or identified using a dissecting microscope. In addition, the Breteau index method requires a long time of home visits, and the special box is large in size, which consumes a lot of physical energy to carry. Especially when a dengue fever epidemic occurs, the monitoring scope and frequency increase. This relatively bulky box with incomplete tools affects work efficiency.

[0003] In order to reduce the workload of grassroots vector control technicians, a mosquito larvae amplification and identification device is needed to carry out Breteau index monitoring without carrying a large number of tools and to quickly and accurately identify mosquito larvae species through their respiratory tubes, so as to provide technical support for the prevention and control of mosquito-borne infectious diseases such as dengue fever and the evaluation of epidemic treatment effects. Summary of the invention

[0004] In order to solve the problems of the prior art, the present invention provides a mosquito larvae amplification and identification device.

[0005] In order to solve the above technical problems, the present invention is implemented by the following technical solutions: a mosquito larvae amplification and identification device, comprising:

[0006] A mosquito larvae magnification sample dish, which consists of a square dish and a circular connector disposed on the top of the square dish, and is used to place and magnify mosquito larvae samples for observation. The top of the circular connector is threadedly sleeved with a dish cover, and at least part of the dish cover has a magnification function, and is used to place, magnify, observe and protect mosquito larvae samples.

[0007] The mosquito larvae suction device comprises a straw, a suction nozzle connected to one end of the straw, and an ear cleaning bulb connected to the other end of the straw, and is used for sucking and moving mosquito larvae samples into the mosquito larvae magnification sample dish for observation.

[0008] In this implementation, during the preparation phase, the staff:

[0009] Make sure the square dish and lid of the mosquito larvae magnification sample dish are clean and intact.

[0010] Check whether the straw, nozzle and ear bulb of the mosquito larvae suction device are functioning properly.

[0011] Prepare other auxiliary tools as needed, such as magnifying glasses, microscopes, notebooks, etc.

[0012] Sample collection:

[0013] Use the nozzle of a mosquito larvae extractor to gently touch the water source containing the mosquito larvae.

[0014] By squeezing the ear bulb, negative pressure is created to suck the mosquito larvae into the straw.

[0015] Release the ear cleansing bulb, move the straw above the square dish, squeeze the ear cleansing bulb again, and release the mosquito larvae into the square dish.

[0016] Sample observations:

[0017] Put the lid on the square dish, making sure the magnifying function of the lid is aimed at the mosquito larvae sample.

[0018] Through the magnifying function of the dish lid, carefully observe the morphological characteristics of the mosquito larvae, such as body shape, color, respiratory tube structure, etc.

[0019] If necessary, use a magnifying glass or microscope to further magnify the details.

[0020] Data recording and analysis:

[0021] Based on the observed morphological characteristics of the mosquito larvae, record relevant information, such as the type, quantity, health status, etc. of the mosquito larvae.

[0022] Analyze data and assess the density and distribution of Aedes mosquito populations in the surveillance areas.

[0023] Equipment cleaning and storage:

[0024] After the observation, use clean water to clean the square dish, dish cover and straw to ensure that there is no residue.

[0025] After the device is dried, store it in a dry, ventilated place for next use.

[0026] In some specific embodiments, the square dish is made of transparent material to facilitate observation of mosquito larvae samples.

[0027] In some specific embodiments, the circular connector is designed to facilitate connection or fixation with other observation devices or accessories.

[0028] In some specific embodiments, the suction tube is made of a flexible material to facilitate adjustment of the position and angle of the suction nozzle to facilitate suction of mosquito larvae samples.

[0029] In some embodiments, an ear bulb is used to provide the negative pressure required to aspirate mosquito larvae samples.

[0030] In some specific embodiments, the square dish is a square with a cross section of 25 mm in length and width, the inner diameter of the circular connector is set to 20 mm, and the inner diameter of the dish cover is set to 22 mm;

[0031] The length of the straw is set to 70-100 mm, and the inner diameter of the nozzle is set to 2-2.5 mm.

[0032] In some embodiments, the magnifying function of the dish cover is achieved by including but not limited to an integrated convex lens, so that technicians can observe the morphological characteristics of mosquito larvae samples in more detail.

[0033] The beneficial effects of the present invention are:

[0034] 1. The present invention reduces the burden on grassroots vector control technicians when conducting Aedes mosquito monitoring. Compared with similar products, this product is simple and lightweight, more convenient to carry, and reduces manpower consumption; it improves the efficiency of Aedes mosquito monitoring by grassroots vector control technicians. When conducting Aedes mosquito larvae monitoring, grassroots personnel often need to spend a lot of time identifying the species of mosquito larvae, which affects the efficiency of mosquito larvae monitoring. And the accuracy of the identification results cannot be guaranteed by naked eye observation alone. This product can magnify the mosquito larvae several times through the magnifying characteristics of the mosquito larvae sample dish cover, assisting technicians to quickly and accurately identify the species of mosquito larvae, thereby improving work efficiency and accuracy; and helping to quickly evaluate the emergency response effects and risk assessment of mosquito-borne infectious diseases such as dengue fever. By quickly and accurately identifying the species of mosquito larvae and quickly evaluating the mosquito-borne control effect, it is of great help to the evaluation of the emergency response effects and risk assessment of the epidemic;

[0035] 2. Through the magnification function integrated on the dish cover (such as a convex lens), this device significantly improves the observation accuracy of mosquito larvae samples. Technicians can more clearly see the morphological details of the mosquito larvae, such as body shape characteristics, body color changes, respiratory tube structure, etc., so as to achieve rapid and accurate identification of the mosquito larvae species. This high-precision observation capability is crucial for vector control work, and helps to promptly discover and control potential sources of mosquito-borne infectious diseases. This device is cleverly designed, compact in structure, and easy to carry and use. The mosquito larvae suction device adopts a flexible straw and ear washing ball design, allowing technicians to easily adjust the position of the suction nozzle, accurately absorb mosquito larvae samples, and transfer them to the magnified sample dish for observation. This design not only simplifies the operating process, but also improves work efficiency, allowing the device to perform well in outdoor or laboratory environments;

[0036] 3. The design of the dish cover not only provides a magnification function, but also plays a role in protecting the sample. During the observation process, the dish cover can prevent external impurities or contaminants from entering the sample dish, ensuring the purity of the sample and the accuracy of the observation results. At the same time, the transparent and durable square dish material (such as polyphenylene sulfide PPS) can resist wear and corrosion in daily use, extending the service life of the equipment. The mosquito larvae magnification and identification device of the present invention provides a high-efficiency and accurate tool for grassroots vector control technicians, which helps them better understand the population dynamics and distribution of mosquito vectors such as Aedes mosquitoes. By regularly monitoring and identifying mosquito larvae samples, technicians can promptly discover and control potential mosquito-borne infectious disease risks, providing a scientific basis for formulating effective prevention and control strategies.

[0040] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 making creative work are within the scope of protection of the present invention.

[0041] like Figure 1 to Figure 2 The mosquito larvae magnification and identification device shown includes: a mosquito larvae magnification sample dish 1, which is composed of a square dish 11 and a circular connector 111 arranged at the top of the square dish 11, and is used to place and magnify mosquito larvae samples for observation. The top of the circular connector 111 is threadedly sleeved with a dish cover 12, and the dish cover 12 at least partially has a magnification function, and is used to place, magnify, observe and protect mosquito larvae samples; a mosquito larvae suction device 2, which includes a straw 21, a suction nozzle 22 connected to one end of the straw 21, and an ear cleaning ball 23 connected to the other end of the straw 21, and is used to suck and move mosquito larvae samples into the mosquito larvae magnification sample dish 1 for observation.

[0042] The square dish 11 is made of transparent material to facilitate observation of mosquito larvae samples. The circular connector 111 is designed to facilitate connection or fixation with other observation equipment or accessories.

[0043] The suction tube 21 is made of flexible material, so as to adjust the position and angle of the suction nozzle 22 to facilitate the suction of mosquito larvae samples. The ear cleaning ball 23 is used to provide the negative pressure required for suction of mosquito larvae samples.

[0044] The square dish 11 is a square with a cross section of 25 mm in length and width. The inner diameter of the circular connector 111 is set to 20 mm, and the inner diameter of the dish cover 12 is set to 22 mm. The length of the straw 21 is set to 70-100 mm, and the inner diameter of the nozzle 22 is set to 2-2.5 mm.

[0046] Example: Figure 1 to Figure 2 As shown, a mosquito larvae amplification and identification device of the present invention comprises:

[0047] Mosquito larvae magnification sample dish 1: It consists of a square dish 11 and a circular connector 111 arranged at the top of the square dish 11. The material of the square dish 11 is a transparent material (such as polyphenylene sulfide PPS or transparent hard plastic) to facilitate the observation of mosquito larvae samples. The cross-section of the square dish 11 is a square with a length and width of 25 mm, which is convenient for accommodating an appropriate amount of mosquito larvae samples. The inner diameter of the circular connector 111 is set to 20 mm, which is convenient for connecting or fixing with other observation equipment or accessories (such as microscopes, magnifying glasses, etc.). The top threaded sleeve of the circular connector 111 is connected to a dish cover 12, and the inner diameter of the dish cover 12 is set to 22 mm, which is slightly larger than the inner diameter of the circular connector 111 to ensure a tight fit. The dish cover 12 at least partially has a magnification function, which is achieved by an integrated convex lens, and the magnification can be adjusted as needed to facilitate technicians to observe the morphological characteristics of the mosquito larvae samples more carefully.

[0048] The mosquito larvae suction device 2 includes a straw 21, a nozzle 22 connected to one end of the straw 21, and an ear cleaning ball 23 connected to the other end of the straw 21. The straw 21 is made of a flexible material (such as soft plastic) and has a length of 70-100 mm, which is convenient for adjusting the position and angle of the nozzle 22 to adapt to mosquito larvae samples of different sizes and observation environments. The inner diameter of the nozzle 22 is set to 2-2.5 mm to ensure that a single or multiple mosquito larvae samples can be easily sucked while avoiding excessive damage to the mosquito larvae. The ear cleaning ball 23 is used to provide the negative pressure required to suck the mosquito larvae samples. By squeezing the ear cleaning ball 23, a negative pressure is formed inside the straw 21, thereby sucking the mosquito larvae samples through the nozzle 22.

[0049] Directions:

[0050] Use the suction nozzle 22 of the mosquito larvae suction device 2 to gently touch the water source containing mosquito larvae.

[0051] Negative pressure is generated by squeezing the ear cleaning bulb 23 to suck mosquito larvae into the suction tube 21 .

[0053] The dish cover 12 is placed on the square dish 11, and it is ensured that the magnifying function of the dish cover 12 is aimed at the mosquito larvae sample.

[0054] Through the magnifying function of the dish cover 12, the morphological characteristics of the mosquito larvae, such as body shape, color, respiratory tube structure, etc., can be carefully observed.

[0055] Based on the observed morphological characteristics of the mosquito larvae, record relevant information, such as the type, quantity, health status, etc. of the mosquito larvae.

[0056] After the observation is finished, the square dish 11, the dish cover 12 and the straw 21 are cleaned with clean water to ensure that there is no residue. After the equipment is dried, it is stored in a dry and ventilated place for next use.

[0057] The mosquito larvae magnification and identification device of the present invention achieves efficient and accurate observation and identification of mosquito larvae samples by optimizing the design of the mosquito larvae magnification sample dish and the mosquito larvae suction device. The magnification function of the dish cover 12 improves the clarity of observation, allowing technicians to observe the morphological characteristics of mosquito larvae samples more carefully, thereby accurately identifying their species. In addition, the entire device is designed to be lightweight and portable, which facilitates technicians to conduct rapid and accurate mosquito larvae observation in outdoor or laboratory environments.
