Abstract
Description
Technical Field
[0001] The utility model relates to a laboratory device, in particular to a novel Aedes mosquito laboratory blood feeding device. Background Art
[0002] Due to the characteristics of Aedes mosquitoes, they can only reproduce and lay eggs after sucking blood. Without sucking blood, they cannot reproduce and lay eggs. In the past, in the laboratory, staff exposed their arms for them to suck blood and lay eggs, which is not advisable for humans. Alternatively, they used mice to suck blood and reproduce and lay eggs. This method has relatively high requirements for laboratory specifications, including preventing mice from escaping or endangering the laboratory, and is costly and has high safety requirements. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a novel blood feeding device for Aedes mosquitoes in the laboratory, which solves the problem of feeding blood to Aedes mosquitoes raised in the laboratory. We artificially breed Aedes mosquitoes and study their drug resistance.
[0004] The technical problem to be solved by the utility model is achieved through the following technical solutions:
[0005] A novel Aedes mosquito laboratory blood feeding device is characterized in that it includes a heating and constant temperature main frame, the heating and constant temperature main frame is fixedly connected to a chassis, a constant temperature heater is fixedly arranged under the chassis; a groove is arranged on the upper surface of the chassis, a magnet is fixedly arranged on the bottom surface of the groove; a magnet is also arranged at the bottom of the blood feeding plate, which can be attracted by the magnet on the bottom surface of the groove to fix the blood feeding plate; a detachable grid is arranged in the middle of the heating and constant temperature main frame; and a gauze cover is arranged outside the heating and constant temperature main frame.
[0006] The mesh outer cover has a zipper structure on one side and a cuff structure on the other side.
[0007] Preferably, the thermostatic heater is provided with a display, a control button, and a power cord jack, and the temperature is controlled at 0-50° C., and can be purchased on the market.
[0008] Preferably, the bottom of the blood feeding plate is also provided with a magnet, which can attract the magnet on the bottom of the groove to fix the blood feeding plate, so that the blood feeding plate can be stably adsorbed in the groove by the magnet. The size of the groove is preferably 42mm-44mm wide and 2mm deep.
[0009] Preferably, the blood feeding dish is cylindrical, made of iron, 3-4 mm high and 40 mm in diameter.
[0010] Preferably, the heating constant temperature main frame is a rectangular parallelepiped with a frame height of 500 mm and a length and width of 400 mm.
[0011] Preferably, the bottom layer is provided with five grooves for placing the blood feeding plate, and the magnet fixes the blood feeding plate. The middle layer grid plate is provided with clean water for the fish to lay eggs and reproduce.
[0012] The gauze outer cover is a gauze with a height slightly greater than 500mm and a length and width slightly greater than 400mm. One side of the gauze outer cover is provided with a zipper structure and the other side is provided with a cuff structure, and the cuff is a sleeve with a diameter of 120mm and a length of 300mm.
[0013] The utility model has the following beneficial technical effects:
[0014] The novel Aedes mosquito laboratory blood feeding device can use sheep blood or other blood in the laboratory. Sheep blood is specially sold. The constant temperature heater can keep the blood warm, simulate human body temperature, and directly provide blood for Aedes mosquitoes. Aedes mosquitoes reproduce and lay eggs in the clean water placed in the middle grid layer to produce offspring, so that their ecology and drug resistance can be observed and monitored. The utility model can reduce costs and increase safety. BRIEF DESCRIPTION OF THE DRAWINGS
