Description

Technical Field

[0001] This utility model relates to the field of miracidia incubation technology, and in particular to a miracidia incubation device. Background Technology

[0002] Schistosomiasis, a parasitic disease that seriously endangers human health and public health security, has a wide prevalence, especially in rural areas and water-related areas such as lakes. Accurate and efficient pathogen detection is a core prerequisite for disease prevention, control, and treatment intervention. Among various schistosomiasis detection techniques, the miracidia hatching method has become a key technical means for field epidemiological investigations, source screening, and efficacy evaluation due to its relatively simple operation, low cost, and ability to directly reflect infectivity. Its detection principle is to simulate the hatching conditions of schistosome eggs in the natural environment, causing the miracidia inside the eggs to hatch, and then observe the movement characteristics of the miracidia to determine whether the sample is infected.

[0003] The hatching process of miracidia is highly sensitive to environmental temperature, which directly determines hatching efficiency and detection accuracy. Extensive experimental research and clinical practice have confirmed that the optimal temperature range for schistosomiasis miracidia hatching is 25℃-30℃. Within this temperature range, the hatching rate can reach over 85%, and the hatching cycle is stable (usually 4-6 hours), minimizing false negative results due to insufficient hatching. If the temperature is below 20℃, the hatching speed will slow significantly, the hatching cycle will extend to over 12 hours, and some eggs may even enter a dormant state and fail to hatch. Temperatures above 32℃ will cause heat damage to the eggs, leading to decreased miracidia viability and increased mortality, which also seriously affects the reliability of the detection results.

[0004] However, in field testing scenarios in schistosomiasis-endemic areas, such as remote rural areas, lake areas, and temporary epidemic prevention points, existing miracidia hatching devices have significant technical shortcomings: most current mainstream hatching equipment is designed as a fixed laboratory unit, which is bulky and relies on an external power source, making it unsuitable for field operations where there is no fixed power supply and space is limited; to meet portability requirements, field operations typically use a "room temperature hatching" mode, which directly utilizes the natural ambient temperature for hatching—this method is entirely affected by fluctuations in external temperature. In early spring, late autumn, or in areas with large temperature differences between day and night, the temperature is far below the optimal hatching range, resulting in low detection efficiency; during the high temperatures of summer, excessive temperature can easily damage the eggs, leading to deviations in test results, severely restricting the accuracy and timeliness of field schistosomiasis screening.

[0005] To address the technical challenges in the aforementioned field operation scenarios, there is an urgent need to design a miracidia incubation device that balances portability and temperature control. Utility Model Content

[0006] To address the above shortcomings, this utility model provides a miracidia incubation device that is both portable and can control the temperature at the optimal incubation temperature.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A miracidia hatching device includes a hatching tank and a multifunctional component. The hatching tank includes hatching bottles and a water bath surrounding it. The multifunctional component includes a mounting plate and a heating rod. The heating rod is mounted on the lower part of the mounting plate, which is detachably mounted on the periphery of the water bath. The heating rod extends into the water bath. In use, sufficient water is placed in the water bath, and culture medium is poured into the hatching bottles. The water in the water bath is heated by the heating rod to prevent the culture medium in the hatching bottles from becoming too cold, maintaining it at the optimal culture temperature. Water bath heating also allows for better control and prevents scalding of the eggs.

[0008] Preferably, it also includes a mounting base, which is provided with a mounting tray groove that matches the incubator. Multiple support legs are evenly arranged around the lower part of the mounting tray groove, and anti-slip pads are also provided at the lower part of the support legs. A battery is also provided at the lower part of the mounting tray groove, and the battery is electrically connected to the heating rod.

[0009] Preferably, it also includes a drain valve, which is located at the bottom of the incubation bottle and connected to the incubation bottle. This facilitates the discharge of the culture medium after the culture is completed.

[0010] Preferably, a limiting ring is provided around the mounting plate, and the outer diameter of the limiting ring is larger than the outer diameter of the water bath.

[0011] Preferably, the incubation bottle also includes an observation tube. A connecting tube with threads is located at the top of the incubation bottle, and the inner wall of the observation tube has a matching internal thread. A filter plate is also installed inside the observation tube, which has graduations. In use, the culture medium is first poured into the incubation bottle through the connecting tube. Then, the observation tube is connected to the connecting tube via threads. Water is added again until it reaches the top graduation mark, typically 0-4 cm. The filter plate isolates impurities in the culture medium from the observation tube, allowing only the miracidia larvae to pass through, keeping the upper liquid clear for easy observation.

[0012] Preferably, it also includes an integrated control component, which is mounted on the upper part of the mounting plate and electrically connected to the heating rod and the battery. The integrated control component can control the heating rod to heat the water in the water bath and can be connected to a mobile phone for easy operation.

[0013] Preferably, the multifunctional component also includes multiple lamps, which are installed on the lower part of the mounting plate and extend into the water bath. The multiple lamps are electrically connected to the integrated control component and the battery to provide illumination for the miracidia.

[0014] Preferably, the multifunctional component also includes a connecting rod and a waterproof turbofan. The connecting rod is located at the bottom of the mounting plate and extends into the water bath. Multiple waterproof turbofans are evenly distributed on the connecting rod. The multiple waterproof turbofans are electrically connected to the integrated control component and the battery to agitate the water in the water bath and prevent local overheating.

[0015] Preferably, the multifunctional component also includes a temperature sensor, which is located at the bottom of the mounting plate and extends into the water bath. The temperature sensor is electrically connected to the integrated control component and the battery, monitors the temperature, and transmits the data to the integrated controller. The integrated controller uses the data to control the heating rod to heat up or stop working.

[0016] Compared with existing technologies, the beneficial effects of this utility model are as follows: The structure of the incubation tank, which includes an incubation bottle and an outer water bath, and a heating rod of a multi-functional component that extends into the water bath through a detachable mounting plate, precisely solves the core problems of "difficult temperature control" and "poor portability" in field incubation. On the one hand, the water bath forms an indirect heating buffer layer, and the heating rod can evenly regulate the water temperature, keeping the culture medium stable in the optimal range of 25℃-30℃. This avoids insufficient incubation at low temperatures and damage to insect eggs at high temperatures, resulting in a miracidia hatching rate of over 85% and a cycle shortened to 4-6 hours, significantly improving detection accuracy. On the other hand, the detachable mounting plate allows the core components to be disassembled and stored, reducing space occupation. It also eliminates the need for complex external equipment, making operation simple and suitable for field scenarios with no power supply and limited space. It balances practicality and portability, breaking through the bottlenecks of existing technologies. Attached Figure Description

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] This embodiment provides a miracidia incubation device, aiming to provide a miracidia incubation device that is both portable and can control the temperature at the optimal incubation temperature, such as... Figures 1-5 As shown, the device includes an incubation tank 1, which serves as the core supporting component for miracidia incubation. The incubation tank 1 includes an incubation bottle 101 and a water bath 102 surrounding the incubation bottle 101. The incubation bottle 101 is made of transparent, high-temperature resistant glass to meet the volume requirements of the culture medium for a single test. The water bath 102 has a ring-shaped hollow structure, with its inner wall tightly fitted to the outer wall of the incubation bottle 101. The height of the water bath 102 is the same as the height of the incubation bottle 101. This structural design ensures that the water in the water bath 102 can evenly surround the incubation bottle 101, laying the foundation for subsequent temperature control through water bath heating. Based on the incubation tank 1, a multi-functional component 2 is provided, which includes a mounting plate 201 and a heating rod 204. The mounting plate 201 is circular in shape to facilitate subsequent installation and mating with the water bath 102. The length of the heating rod 204 is determined according to the height of the water bath 102, ensuring that the heating rod 204 can fully extend into the water bath 102 without contacting the outer wall of the incubation bottle 101. The heating rod 204 is fixedly installed on the lower part of the mounting plate 201 with bolts. In use, sufficient purified water is injected into the water bath 102, and the prepared miracidia culture solution is poured into the incubation bottle 101. The heating rod 204 heats the water in the water bath 102. Utilizing the uniformity of water bath heating, excessive temperature fluctuations in the culture solution within the incubation bottle 101 are avoided, while also preventing direct heating that could scald the eggs, ensuring that the culture solution temperature remains stable within the optimal incubation range of 25℃-30℃. To improve the stability of the device in the field and the convenience of power supply, a mounting base 3 is also provided. Its upper part is equipped with a mounting tray groove 301 that matches the incubator 1. The inner diameter of the mounting tray groove 301 is consistent with the outer diameter of the water bath 102, ensuring that the incubator 1 can be stably placed in the mounting tray groove 301 without shaking. Three support legs 302 are evenly arranged circumferentially at the lower part of the mounting tray groove 301, and the support legs 302 are fixed to the mounting tray groove 301 by welding. A layer of rubber anti-slip pad 303 is attached to the lower part of each support leg 302. The surface of the anti-slip pad 303 is provided with a diamond-shaped anti-slip pattern, which can increase the friction between the support leg 302 and the ground, preventing the device from sliding on uneven ground in the field. At the lower center of the mounting tray groove 301, there is also a battery mounting cavity 5. A rechargeable lithium battery 5 is fixedly installed in the battery mounting cavity. The battery 5 is electrically connected to the heating rod 204 through a wire to meet the power needs of a single field test. To facilitate the drainage of the culture medium after hatching, a drain valve 4 is installed at the bottom of the hatching bottle 101. The drain valve 4 is a corrosion-resistant plastic ball valve, with its interface threaded to the drain outlet at the bottom of the hatching bottle 101. The connection is sealed with Teflon tape to prevent leakage of the culture medium. The handle of the drain valve 4 extends to the outside of the hatching bottle 101, allowing operators to manually control the valve's opening and closing. After the miracidia hatching and testing are completed, opening the drain valve 4 allows for the rapid drainage of the culture medium from the hatching bottle 101, eliminating the need for a pouring device and simplifying subsequent cleaning operations. To further ensure the positioning accuracy of the mounting plate 201 and the water bath 102 during installation, a limiting ring 202 is provided on the outer periphery of the mounting plate 201. The limiting ring 202 and the mounting plate 201 are made of the same material and are integrally formed. When the mounting plate 201 is fitted around the water bath 102, the limiting ring 202 can abut against the top edge of the water bath 102, restricting the mounting plate 201 from sliding further downward, and at the same time preventing the heating rod 204 from contacting the bottom of the water bath 102 and causing damage due to the mounting plate 201 being installed too deeply. To facilitate observation of miracidia hatching and filter impurities in the culture medium, the hatching flask 101 also includes an observation tube 103. A connecting tube 105 is integrally formed with the hatching flask 101 on one side of the upper part of the hatching flask 101, and the outer wall of the connecting tube 105 has external threads. The observation tube 103 is made of transparent glass, is 10-12 cm long, and has the same inner diameter as the connecting tube 105. The lower inner wall of the observation tube 103 has internal threads that match the external threads of the connecting tube 105, allowing for a detachable connection between the observation tube 103 and the connecting tube 105. A rubber sealing ring is provided at the threaded connection to ensure a tight seal and prevent leakage. A filter plate 104 is fixedly installed inside the observation tube 103, 2-3 cm from its bottom, via a slot. The pore size of the filter plate 104 allows miracidia to pass through while blocking impurities in the culture medium from entering the observation tube 103, keeping the liquid inside the observation tube 103 clear. The outer wall of the observation tube 103 is marked with graduations ranging from 0 to 4 cm. In use, the culture medium is first poured into the incubation bottle 101 through the connecting tube 105. Then, the observation tube 103 is connected to the connecting tube 105 by a thread. Pure water is added into the observation tube 103 until it is level with the uppermost graduation. The operator can directly observe the movement of the miracidia through the observation tube 103. The graduations can help determine whether the liquid volume meets the testing requirements. To achieve precise control and convenient operation of the heating rod 204, an integrated control component 6 is also provided. The integrated control component 6 has a rectangular plastic housing and is fixed to the upper part of the mounting plate 201 with screws. The integrated control component 6 internally houses a microcontroller, a relay module, a Bluetooth module (or WiFi module), and a power management module. The integrated control component 6 is electrically connected to the heating rod 204 and the battery 5 via wires, which must pass through through holes in the mounting plate 201 and be waterproofed and sealed. A power switch is located on the housing of the integrated control component 6. Furthermore, it can connect to a mobile app via the Bluetooth module (or WiFi module), allowing operators to view the real-time operating status of the device and set the incubation temperature on their mobile phones, greatly improving the ease of operation in the field. Considering the light requirements during miracidia hatching, the multifunctional component 2 also includes lamps 203. Two low-voltage LED lamps 203 are used, and are evenly installed on the lower part of the mounting plate 201 via brackets. The length of the lamps 203 is adapted to the height of the water bath 102, ensuring that the lamps 203 can fully extend into the water bath 102 without interfering with the operation of the heating rod 204. The lamps 203 are electrically connected to the integrated control component 6 and the battery 5 via wires. The integrated control component 6 can control the on / off state of the lamps 203 and the light intensity. Operators can adjust the light parameters via a mobile app or the buttons on the integrated control component 6 according to the hatching requirements of different schistosome species, providing a suitable light environment for miracidia hatching. To prevent excessively high local water temperatures within the water bath 102 and ensure uniform water temperature, the multi-functional component 2 also includes a connecting rod 205 and a waterproof turbine fan 206. The connecting rod 205 is made of stainless steel and is welded to the bottom of the mounting plate 201, ensuring that it can extend vertically into the water bath 102. The waterproof turbine fan 206 is a miniature DC waterproof fan, with 2-3 units provided. The waterproof turbine fan 206 is evenly fixed to the connecting rod 205 with screws, and the blades of the waterproof turbine fan 206 face the same radial direction as the water bath 102 to prevent the blades from contacting the outer wall of the incubation bottle 101 during rotation. The waterproof turbofan 206 is electrically connected to the integrated control component 6 and the battery 5 via wires. The integrated control component 6 can control the start, stop and speed of the waterproof turbofan 206. When the heating rod 204 is working, the waterproof turbofan 206 is turned on. The rotating blades disturb the water in the water bath 102 to form a circulating water flow, so that the water temperature in each area of ​​the water bath 102 is kept consistent, preventing damage to insect eggs due to excessively high local water temperature. To monitor the water temperature in the water bath 102 in real time and achieve automatic temperature control, the multi-functional component 2 also includes a temperature sensor 207. The temperature sensor 207 is fixedly installed on the lower part of the mounting plate 201, with its probe end fully inserted into the water bath 102 and not in contact with the heating rod 204 and the incubation bottle 101, ensuring the accuracy of the measurement data. Temperature sensor 207 is electrically connected to integrated control component 6 and battery 5 via wires. During operation, temperature sensor 207 collects water temperature data in water bath 102 in real time and transmits the data to the microcontroller of integrated control component 6. The microcontroller compares the real-time temperature with the set target temperature: when the real-time temperature is below 25℃, the microcontroller controls the relay module to turn on, causing heating rod 204 to work and heat up; when the real-time temperature is above 30℃, the microcontroller controls the relay module to turn off, stopping heating rod 204 from working; if the real-time temperature exceeds the safe range of 20℃-32℃, integrated control component 6 will also issue an alarm prompt through the display screen and mobile APP to ensure that the water temperature is always within the suitable range for miracidia hatching and to ensure the accuracy of the detection results.
