Description

Technical Field

[0001] This utility model belongs to the field of drug resistance detection technology for medical vectors such as mosquitoes, and particularly relates to a contact tube for detecting drug resistance in mosquitoes. Background Technology

[0002] Mosquitoes and other medical vectors are major vectors for the transmission of various infectious diseases, posing a serious threat to human health and well-being. To address this, the industry typically employs chemical methods such as insecticides for mosquito control. However, continuous and excessive use of insecticides can lead to the development and spread of drug resistance in mosquitoes and other vectors. Therefore, the detection and research of drug resistance in mosquitoes and other medical vectors has become one of the core technologies of concern in the industry.

[0003] Currently, mosquito contact tubes used for testing mosquito resistance all employ a pull-out design with a sliding plate inside a partition to create both isolated and non-isolated environments. However, this design often results in the sliding plate shifting or even coming off if the contact tube is accidentally touched or laid flat, causing mosquitoes to fly out through the gap and affecting the experimental results. Furthermore, the pull-out design often suffers from poor sealing and air leakage. Summary of the Invention

[0004] The purpose of this invention is to provide a contact tube for detecting mosquito resistance. Because the partition and the isolation seat are hinged and rotated, the connection is tight and the reliability is high.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A mosquito resistance testing contact tube includes an upper base, a contact tube connected to the upper base at its lower part, an isolation seat connected to the contact tube at its lower part, a recovery tube connected to the isolation seat at its lower part, and a lower base connected to the recovery tube at its lower part. The isolation seat is also provided with a rotatable partition, which has both a through area and a closed area. The partition is rotatably connected to the isolation seat by a pin.

[0006] Furthermore, the through area is provided with through holes that communicate with the contact tube and the recovery tube; the closed area is a solid plate that isolates the contact tube and the recovery tube.

[0007] Furthermore, the partition is a three-petaled flower shape evenly distributed along the center, that is, an integral plate made up of three equally sized superior arcs smoothly connected together, with at least one superior arc having a through hole at its center and at least one superior arc being a solid partition plate.

[0008] Furthermore, the partition is symmetrically shaped like an 8, with one end being a through area and the other end being a closed area.

[0009] Furthermore, the isolation seat includes an upper interface connected to the drug-contacting cartridge and a lower interface connected to the recovery cartridge. The upper and lower interfaces are connected and a base is fixedly connected to the upper and lower interfaces. The base is provided with a groove through which the partition can rotate.

[0010] Furthermore, both the upper and lower bases are equipped with mesh screens.

[0011] The advantages of this utility model are: since the rotating partition of this application is used instead of the traditional pull-out partition, the specimen flying out due to the partition detaching from the contact cylinder can be avoided, which would affect the experimental results. All connecting parts of the contact cylinder of this application adopt a large pitch, which is convenient and safe to use. Moreover, the rotating partition is safer and more reliable during use.

[0014] like Figure 1 As shown, a mosquito resistance testing contact tube includes an upper base 1, a contact tube 2 located below the upper base and connected to the upper base, an isolation seat 3 located below the contact tube 2 and connected to the contact tube, a recovery tube 4 located below the isolation seat and connected to the isolation seat, and a lower base 5 located below the recovery tube and connected to the recovery tube. Both the upper and lower bases are equipped with mesh screens. The isolation seat also has a rotatable partition 6, which is rotatably connected to the isolation seat via a pin. The partition has both a through area and a closed area. The through area has a through hole communicating with the contact tube and the recovery tube. The closed area has a through hole communicating with the contact tube and the recovery tube. The zone is separated from the contact tube and the recovery tube by a solid plate; the partition is symmetrical in the shape of an 8 or in the shape of a three-petaled flower evenly distributed along the center, that is, it is an integral plate with three equal-sized superior arcs smoothly connected, at least one superior arc has a through hole in the center, and at least one superior arc is a solid partition plate; the rotational connection is more reliable than the traditional pull-out design; the partition seat includes an upper interface 31 connected to the contact tube and a lower interface 32 connected to the recovery tube, the upper and lower interfaces are connected, and a base 33 is fixedly connected to the upper and lower interfaces, and the base is provided with a groove for the partition to rotate through.

[0015] In use, the inner wall of the contact tube can be lined with filter paper soaked in pesticide solution. The pesticide solution is usually obtained by dissolving an insecticide in a 1:2 mixture of white oil and ether. After the solvent in the pesticide solution evaporates, the filter paper is placed on the inner wall of the contact tube, and mosquitoes are placed in the contact tube. After the mosquitoes have been in contact with the pesticide solution for a certain period of time, the partition is rotated so that the end of the partition with the hole is in the receiving cavity, exposing the round hole of the partition, connecting the contact tube and the recovery tube, so that the mosquitoes can move into the recovery tube through the round hole to recover. If it is necessary to change the filter paper of different concentrations of pesticide solution for observation, the partition is rotated so that the solid plate end is screwed into the receiving cavity to isolate the contact tube and the recovery tube. The contact tube is then unscrewed to replace the pesticide solution filter paper. The device can also be laid flat during use without affecting its experimental results.
