[0002] The immunochromatographic test products on the market usually consist of a plastic shell and a test strip fixed in the plastic shell. The plastic shell is provided with corresponding observation windows and sample addition holes. When in use, a dropper is required to first absorb the sample with the dropper and then drop it into the sample addition hole. The operation is cumbersome and prone to errors caused by human factors.

[0003] At present, the utility model with the publication number CN213408734U proposes an immunochromatographic test dropper, including a tube body, the tube body is formed by buckling an upper shell and a lower shell, the front end of the tube body is a liquid suction tip, and the outer wall of the rear end of the tube body is provided with an external thread; an immunochromatographic test strip, the immunochromatographic test strip is clamped between the upper shell and the lower shell of the tube body, and the nitrocellulose membrane of the immunochromatographic test strip is located directly below the detection window; an air bag, the opening of the air bag is provided with an internal thread, and the air bag is screwed to the rear end of the tube body through the internal thread. The sample liquid is directly sucked by the air bag for immunochromatographic detection, which is convenient and quick to use, and no need to cooperate with the dropper for detection, reducing the cost of use; the sample liquid is sucked by squeezing the air bag, which has a more accurate sample liquid suction amount, avoiding errors caused by human factors when dripping the sample liquid with a dropper.

[0004] However, the above-mentioned prior art still has some shortcomings in actual use: 1. The dropper needs to be placed horizontally for a period of time when sampling. Since the dropper is a round rod, the operator needs to hold it continuously, which takes up time; 2. In order to solve the problem of taking up the operator's time, the dropper is usually placed in a tray, but the dropper is a round rod, which is easy to roll and the observation window cannot face upward, affecting the observation.

[0005] To this end, the utility model provides an immunochromatographic test dropper. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model aims to provide an immunochromatographic test dropper to solve the problems raised in the above-mentioned background technology. The utility model has the advantages of being more convenient to place the dropper flat on the spot and having the advantage of higher stability of the dropper lying flat.

[0007] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: an immunochromatographic test dropper, including a tube body, one end of the tube body is provided with an air bag, the outer wall of the tube body is fixedly provided with a pillar close to the air bag, one end of the pillar is connected to a U-shaped frame for damping rotation, the free end of the U-shaped frame is turned with a support rod, the outer peripheral wall of the support rod is provided with a suction cup, the U-shaped frame is also detachably connected to the support rod, and the free ends of the two support rods are fixedly connected with a U-shaped blocking rod.

[0008] Furthermore, a C-shaped clip is welded to one end of the pillar, and the bottom of the U-shaped frame is connected to the C-shaped clip by clipping.

[0009] Furthermore, a rubber sleeve is provided on the U-shaped baffle bar.

[0010] Furthermore, a connecting pipe is fixedly connected to the top of the suction cup, and a positioning hole fixedly connected to the connecting pipe is formed on the outer peripheral wall of the support rod.

[0011] Furthermore, an elastic rubber sealing piece is bonded to the top of the connecting tube, and the inner wall of the suction cup is connected to the inner cavity of the connecting tube.

[0012] Furthermore, a baffle is welded on the top of the connecting pipe, and a vent hole is penetrated through the baffle.

[0013] Furthermore, the connecting pipe and the positioning hole are screwed together to be detachably connected.

[0014] Furthermore, the number of the suction cups on the support rod is at least two and they are distributed along the axial direction.

[0015] The beneficial effects of the utility model are as follows:

[0016] 1. The utility model provides a U-shaped frame on the tube body, and a support rod is provided on the U-shaped frame. The U-shaped frame and the tube body are matched with damping rotation. When the tube body extracts samples through the airbag, the U-shaped frame cooperates with the support rod to support the tube body horizontally, which greatly improves the convenience of placing the dropper horizontally in situ.

[0017] 2. The utility model arranges a suction cup on the support rod. After the dropper is placed on a plane, the suction cup can attract the placement surface, so that the dropper is in a stable placement state. In addition, a connecting tube and an elastic rubber sealing piece located on the top of the connecting tube are arranged on the suction cup. This arrangement makes it more convenient to separate the suction tube from the placement surface.

[0018] 3. The utility model arranges pillars on the pipe body, and the pillars are connected to the U-shaped frame through C-shaped clips. This arrangement enables the pipe body to be quickly connected and separated from the U-shaped frame, and has the advantages of being more convenient to use the pipe body alone or in combination.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] See also Figures 1 to 4 The utility model provides a technical solution: an immunochromatographic test dropper, comprising a tube body 1, an air bag 2 is arranged at one end of the tube body 1, when the air bag 2 is manually pressed, the suction port at the other end of the tube body 1 can generate attraction, and the structure inside the tube body 1 adopts the structure of the prior art mentioned in the background technology.

[0026] In the technical solution, the outer wall of the tube body 1 is fixedly provided with a support 3 close to the airbag 2, one end of the support 3 is connected to a U-shaped frame 4 with damping rotation, the free end of the U-shaped frame 4 is turned with a support rod 5, the support rod 5 is perpendicular to the U-shaped frame 4, and the outer peripheral wall of the support rod 5 is provided with a suction cup 6, specifically, the top of the suction cup 6 is fixedly connected to a connecting tube 61, and the outer peripheral wall of the support rod 5 is provided with a positioning hole 51 fixedly connected to the connecting tube 61. When the U-shaped frame 4 and the tube body 1 are perpendicular, the support rod 5 and the tube body 1 are parallel, and at this time, when the support rod 5 is placed on the placement surface and pressed, the suction cup 6 will be adsorbed on the placement surface.

[0027] The U-shaped frame 4 is also detachably connected to the pillar 3. Specifically, a C-shaped clip 31 is welded to one end of the pillar 3, and the bottom of the U-shaped frame 4 is connected to the C-shaped clip 31 by clipping. The inner cavity of the C-shaped clip 31 and the U-shaped frame 4 are interference fit, so as to realize the damping rotation fit between the U-shaped frame 4 and the pillar 3. Moreover, the above detachable connection method is convenient for the pipe body 1 to be separated and used separately.

[0028] The free ends of the two support rods 5 are fixedly connected to a U-shaped baffle rod 7, which is perpendicular to the support rods 5. The U-shaped baffle rod 7, the two support rods 5 and the U-shaped frame 4 form a rectangular frame when flattened. This arrangement allows the pipe body 1 to be quickly leveled, wherein a rubber sleeve 71 is sleeved on the U-shaped baffle rod 7, which serves to protect the pipe body 1.

[0029] In this embodiment, an elastic rubber sealing piece 611 is bonded to the top of the connecting tube 61. The elastic rubber sealing piece 611 has the function of elastic deformation. The inner wall of the suction cup 6 is connected to the inner cavity of the connecting tube 61. When the suction cup 6 is separated from the adsorption surface, the elastic rubber sealing piece 611 will be recessed into the connecting tube 61, so as to facilitate the separation of the suction cup 6 and the placement surface.

[0030] Furthermore, a baffle 612 is welded on the top of the connecting tube 61, which serves to prevent the elastic rubber sealing piece 611 from convexly deforming, so as to facilitate the exhaust of the suction cup 6 and the placement surface. An air hole 6121 is opened through the baffle 612, which serves to replenish gas in the direction of the elastic rubber sealing piece 611.

[0031] In this embodiment, the connecting tube 61 and the positioning hole 51 are screwed together and detachably connected, wherein the number of the suction cups 6 on the support rod 5 is at least two and distributed along the axial direction. This arrangement facilitates the connection and separation of the connecting tube 61 and the support rod 5 and is easy to manufacture.

[0032] When using the dropper, manually take the tube body 1 and press the airbag 2 to extract the sample liquid, then manually rotate the U-shaped frame 4 outward, the U-shaped frame 4 is unfolded, the blocking rod 7 is pressed against the tube body 1, and then the support rod 5 is placed on the placement surface, the suction cup 6 is in contact with the placement surface, and when the blocking rod 7 is pressed, the suction cup 6 is squeezed and the internal air is discharged outward. At this time, the entire U-shaped frame 4 will be stably placed on the placement surface. At the same time, the tube body 1 will remain in a horizontal state due to the damping matching structure of the C-shaped card 31 and the U-shaped frame 4, and then it will be still for a period of time, and then the changes of the test paper inside the tube body 1 will be observed through the observation window.

[0033] After use, the tube body 1 is manually lifted from the bottom. The suction cup 6 is subjected to an upward pulling force. Due to the negative pressure in the connecting tube 61, the elastic rubber sealing piece 611 at the top of the connecting tube 61 is elastically deformed and recessed downward. The volume in the connecting tube 61 becomes smaller, and the suction cup 6 will be easily separated from the placement surface.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
