Description

Technical Field

[0001] This utility model relates to the field of test kit technology, and in particular to a dengue fever rapid test kit. Background Technology

[0002] Dengue fever is an epidemic virus, and the dengue fever rapid test kit is a method used to qualitatively detect dengue virus IgM and IgG antibodies in human serum, plasma, and whole blood.

[0003] In existing technologies, testers must use a dropper to add reagents to the sample wells. However, the sample wells on the kits are small. If the dropper is not operated properly during the addition process, the reagent may drip around the sample well, resulting in reagent waste or cross-contamination. At the same time, after the reagent is added, the sample well is exposed and may come into contact with the external environment. Bacteria or impurities in the air may enter the well, affecting the quality of the reagent or the reliability of the test results. Therefore, it is necessary to propose a dengue fever rapid test kit to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid dengue fever detection kit.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dengue fever rapid test kit includes a kit body. The upper surface of the kit body has a viewing window and a sample application hole. A groove is formed on the upper surface of the kit body, and a rotating rod slides and rotates within the groove. A guide ring and a dust cover are fixedly connected to the outer wall of the rotating rod. The axis points of the guide ring and the dust cover are located on the same horizontal plane and are symmetrically positioned. The horizontal heights of the guide ring and the dust cover are not the same. The dust cover is in close contact with the opening of the sample application hole. A limiting rod is installed above the end face of the kit body. The outer wall of the limiting rod is U-shaped. The limiting rod is inclined and its opening direction is horizontal. One end of the limiting rod extends vertically to the end face of the kit body. Limiting mechanisms are installed on the outer walls of both the guide ring and the dust cover to limit their movement.

[0007] Preferably, a connecting rod is fixedly connected to the outer wall of the guide ring, the connecting rod is engaged in the U-shaped groove of the limiting rod, and a stop bar is fixedly connected to the outer wall of the dust cover, the outer wall of the stop bar is L-shaped, and the outer wall of the stop bar is in contact with the outer wall of the limiting rod.

[0008] Preferably, a slide plate is slidably connected within the slide groove, and the rotating rod is rotatably connected to the outer wall of the slide plate.

[0009] Preferably, a limiting ring is fixedly connected at the opening of the slide groove, and the inner diameter of the limiting ring is smaller than the outer diameter of the slide plate.

[0010] Preferably, a spring is fixedly connected to the bottom of the groove, and the other end of the spring is fixedly connected to the lower end face of the slide plate.

[0011] Preferably, both the inner wall of the chute and the outer wall of the slide plate are circular, and there is a certain small gap between the outer wall of the slide plate and the inner wall of the chute.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model ensures that the dropper is always precisely aligned with the sample dispensing hole during the sample dispensing process by setting up components such as a guide ring, a limiting rod, and a dust cover, thus preventing reagent spillage or contamination of the surrounding area. At the same time, the dust cover is tightly fitted with the sample dispensing hole by the elastic restoring force of the spring during the non-sample dispensing stage, forming a dynamic sealing barrier, effectively isolating external environmental pollution, and significantly improving the reliability of test results and reagent utilization.

[0014] 2. This utility model achieves rapid switching and precise positioning of the dust cover and guide ring by using a sliding plate and a rotating rod, combined with the elastic reset function of the spring. This allows for rapid dengue fever testing. The cooperation between the limit rod and the stop rod further enhances the stability of the mechanism and prevents the dust cover and guide ring from shifting during operation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A dengue fever rapid test kit includes a kit body 1. The upper end face of the kit body 1 is provided with a viewing window 2 and a sample application hole 3. A sliding groove 5 is opened on the upper end face of the kit body 1. A rotating rod 9 slides and rotates in the sliding groove 5. A guide ring 8 and a dust cover 4 are fixedly connected to the outer wall of the rotating rod 9. The axis points of the guide ring 8 and the dust cover 4 are located on the same horizontal plane and are symmetrical to each other. The horizontal heights of the guide ring 8 and the dust cover 4 are not the same. The dust cover 4 is in close contact with the opening of the sample application hole 3. A limiting rod 13 is installed above the end face of the kit body 1. The outer wall of the limiting rod 13 is U-shaped. The limiting rod 13 is inclined and the opening direction is horizontal. One end of the limiting rod 13 extends vertically to the end face of the kit body 1. The outer walls of the guide ring 8 and the dust cover 4 are both equipped with limiting mechanisms to limit their movement.

[0022] Specifically, by rotating the rotating rod 9, the dust cover 4 or the guide ring 8 can be rotated to be directly above the sample dispensing hole 3. The limiting rod 13 can be used to ensure that the dust cover 4 and the guide ring 8 are both in the same center as the sample dispensing hole 3. The guide ring 8 can guide the dropper, while the dust cover 4 can seal the sample dispensing hole 3 after the reagent has been dispensed.

[0023] A connecting rod 12 is fixedly connected to the outer wall of the guide ring 8. The connecting rod 12 is snapped into the U-shaped groove of the limiting rod 13. A stop rod 10 is fixedly connected to the outer wall of the dust cover 4. The outer wall of the stop rod 10 is L-shaped and contacts the outer wall of the limiting rod 13.

[0024] Specifically, the adjustable height of the rotating rod 9 allows the connecting rod 12 and the stop rod 10 to slide to different positions on the limiting rod 13. When the stop rod 10 is sealing the sample feeding hole 3, its horizontal height is lower than that of the connecting rod 12, thereby ensuring that the sample feeding hole 3 is effectively sealed. At the same time, the design of the limiting rod 13 ensures that the stop rod 10 and the connecting rod 12 are effectively limited.

[0025] A slide plate 7 is slidably connected inside the slide groove 5. A rotating rod 9 is rotatably connected to the outer wall of the slide plate 7. A limit ring 11 is fixedly connected at the opening of the slide groove 5. The inner diameter of the limit ring 11 is smaller than the outer diameter of the slide plate 7. A spring 6 is fixedly connected to the bottom of the slide groove 5. The other end of the spring 6 is fixedly connected to the lower end face of the slide plate 7.

[0026] Specifically, the spring 6 can increase the elastic pressure to a certain extent. When the reagent is dripped through the guide ring 8, the spring 6 is in the restoring state. When sealing the sample dispensing hole 3, the spring 6 is in the compressed state under the limiting action of the limiting rod 13, which further improves the sealing effect when sealing the sample dispensing hole 3.

[0027] Both the inner wall of the slide 5 and the outer wall of the slide plate 7 are circular, and there is a certain small gap between the outer wall of the slide plate 7 and the inner wall of the slide 5.

[0028] In this invention, when the device is in use: In the initial state, the dust cover 4 is tightly fitted with the opening of the sample feeding hole 3 by the elastic restoring force of the spring 6, forming a sealing barrier. At this time, the L-shaped outer wall of the stop rod 10 contacts the outer wall of the inclined limiting rod 13, restricting the horizontal displacement of the dust cover 4, ensuring complete coverage of the sealing surface, and effectively isolating external environmental pollution.

[0029] When reagent needs to be added, the operator presses the sliding plate 7 to move it down along the groove 5, compressing the spring 6 and causing the rotating rod 9 to rotate. The rotation of the rotating rod 9 drives the guide ring 8 to switch from clockwise to directly above the sample dispensing hole 3. During this process, the connecting rod 12 slides along the inner wall of the U-shaped groove of the limiting rod 13 and engages to ensure that the central axis of the guide ring 8 is precisely aligned with the sample dispensing hole 3. When adding reagent, the operator inserts the dropper into the guide ring 8. The annular structure of the guide ring 8 radially constrains the dropper, ensuring that the reagent is accurately injected into the sample dispensing hole 3 in a vertical direction, preventing liquid spillage or contamination of the surrounding area.

[0030] After the sample is added, rotate the lever 9 counterclockwise so that the dust cover 4 covers the sample hole 3 again. At this time, the L-shaped outer wall of the stop lever 10 contacts the outer wall of the limit lever 13 and abuts against the limit lever 13 under the action of the spring 6 to prevent displacement. With the continuous pressure of the spring 6, the contact surface between the dust cover 4 and the sample hole 3 generates a uniform pressing force to form a dynamic seal.

[0031] During the testing phase, the operator observes the reagent reaction status in real time through the viewing window 2, while the dust cover 4 maintains the closed environment inside the sample dispensing port 3 to prevent impurities in the air from interfering with the test results.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
