[0002] The commonly used dropper is composed of a rubber nipple and a pointed glass tube. It is mainly used to absorb or add a small amount of reagent, as well as absorb the upper clear liquid and separate the precipitate. When adding dropwise, the dropper should be kept vertically above the container to avoid tilting and inversion. It should not be inserted into the container or touch the container wall. Except for absorbing the solution, the tip of the tube should not touch other objects to avoid contamination by impurities. The tube cannot be used for two purposes.

[0003] In order to avoid clogging inside the pipeline, the existing dropper generally adds a filter plate at the position of the drip suction head to filter out large particles of impurities in the liquid to prevent them from entering the pipeline and causing clogging.

[0029] Example: Figures 1 to 6 As shown, a medical test anti-clogging dropper includes a dropper body 1, one side of the dropper body 1 is threadedly connected to a liquid dripping head 2 (known technology), which is not improved by the present invention, so it is not described here, a rubber balloon 3 is threadedly connected to the side of the dropper body 1 away from the liquid dripping head 2, and an anti-clogging component 4 is clamped between the dropper body 1 and the rubber balloon 3;

[0030] The anti-clogging component 4 includes a positioning plate 41, which is internally slidably connected to a slide rod 42. The positioning plate 41 can provide a certain guiding effect for the movement of the slide rod 42. A filter plate 43 is fixedly connected to one side of the slide rod 42. The outside of the filter plate 43 overlaps the inside of the drip suction head 2. A baffle 44 is fixedly connected to the side of the slide rod 42 away from the filter plate 43. A spring 45 is sleeved on the outside of the slide rod 42. The spring 45 is in a stretched state after the drip suction head 2 is installed, so that the filter plate 43 can be tightly attached to the drip suction head 2. The setting of the spring 45 enables the filter plate 43 to adapt to different drip suction heads 2.

[0031] Both ends of the dropper body 1 are fixedly connected to a connecting column 11, and the exteriors of the two connecting columns 11 are both provided with external threads.

[0032] The inner thread of the dripping suction head 2 is connected to the outer surface of one of the connecting posts 11 , and a slot 12 is provided on one side of the other connecting post 11 . The filter plate 43 is located inside the dripping suction head 2 .

[0033] A threaded sleeve 31 is fixedly connected to one side of the rubber balloon 3 , a clamping block 32 is fixedly connected to one side of the threaded sleeve 31 , the spring 45 is located inside the rubber balloon 3 , and the outside of the clamping block 32 is clamped to the inside of the clamping slot 12 .

[0034] The two sides of the spring 45 are respectively fixedly installed on one side of the positioning plate 41 and the baffle 44. The outside of the positioning plate 41 is fixedly connected to the limiting plate 46. The outside of the limiting plate 46 is clamped to the inside of the slot 12. One side of the clamping block 32 overlaps the top of the limiting plate 46. The tension of the spring 45 ensures that there is no gap between the filter plate 43 and the drip suction head 2. The limiting plate 46 is locked and fixed by the clamping block 32 and the slot 12.

[0035] A plurality of ventilation holes are provided on the top of the positioning plate 41 , and the interior of the plurality of dropper bodies 1 and the interior of the rubber balloon 3 are connected through the ventilation holes, so that the dropper can be conveniently controlled to work through the rubber balloon 3 .

[0037] A medical test anti-clogging dropper, the working principle is as follows:

[0038] 1) During assembly, the anti-clogging component 4 is inserted into the interior of the dropper body 1, so that the limiting plate 46 on the positioning plate 41 is inserted into the interior of the card slot 12, and then the rubber balloon 3 is fixed to the dropper body 1 through the threaded sleeve 31, and at the same time, the card block 32 will cooperate with the card slot 12 to lock the limiting plate 46, and then the dripping suction head 2 is sleeved on the outside of the filter plate 43, and then installed on the dropper body 1. During installation, the outside of the filter plate 43 will be attached to the inside of the dripping suction head 2. As the installation is completed, the slide bar 42 is pushed upward to stretch the spring 45. After the installation is completed, the filter plate 43 can be tightly attached to the inside of the dripping suction head 2, and no gap will be generated between the two during suction. When the filter plate 43 needs to be cleaned, it is only necessary to disassemble the dripping suction head 2 to make it leak out for cleaning, which is quite convenient to use. When the dropper as a whole needs to be cleaned, the rubber balloon 3 and the anti-clogging component 4 can be disassembled and cleaned, which is very convenient to use;

[0039] 2) By setting the spring 45, the filter plate 43 can have a certain range of motion, so that it can be better adapted when using different dripping suction heads 2. When the dripping suction head 2 is contaminated or damaged, it can be replaced in time, further improving the practicality of the device.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] The anti-clogging component 4 in the utility model is composed of a positioning plate 4, a slide rod 42, a filter plate 43, a baffle 44, a spring 45 and a limit plate 46. It has a simple structure and the components are not too precise and compact, which makes it more convenient to install. When cleaning the filter plate 43, it is only necessary to disassemble the drip suction head 2 to clean it. It is very convenient to use. Through the setting of the spring 45, the filter plate 43 can have a certain range of motion, so that when using different drip suction heads 2, it can be better adapted. When the drip suction head 2 is contaminated or damaged, it can be replaced in time. It is very flexible to use, which ensures the practicality of the device.
