Description

TECHNICAL FIELD

[0001] The utility model relates to vitamin content determination technical field, specifically is a kind of vitamin D content determination device of vitamin D drops. BACKGROUND

[0002] In the field of vitamin determination, especially in the content detection work of vitamin D drops, the current widely used is the way of manually adding drops to determination card or detection card to carry out preliminary detection analysis, however, this traditional manual operation mode has many insurmountable drawbacks, which seriously affects the accuracy, reliability and efficiency of detection.

[0003] In the vertical drop aspect, manual operation is difficult to ensure that the dropper is always perpendicular to the sample area of detection card, and it is difficult to accurately maintain the distance between the dropper and the sample area within a suitable range. Under normal circumstances, the height of the dropper is prone to be too high or too low when manually adding drops. When the drop height is too high, the impact force of the drops falling under the action of gravity is large, which can cause the drops to splash out of the sample area, which not only causes the loss of sample, but also makes the actual amount of drops participating in the reaction less than the theoretical amount, ultimately leading to a low detection result and failing to truly reflect the content of vitamin D. On the contrary, if the drop height is too low, the dropper is easy to touch the surface of the detection card, which not only pollutes the dropper with reagents on the detection card, but also affects the subsequent use and the detection accuracy of other samples.

[0004] Regarding the control of drop speed, manual operation cannot guarantee the stability and uniformity of drop speed; during the drop process, the drop speed is often too fast or too slow due to the instability of hand muscles and the lack of precise speed control means. When the drop speed is too fast, the drops will quickly accumulate on the detection card, and cannot be evenly distributed in the entire sample area, resulting in local high or low concentration; such uneven distribution can seriously affect the consistency of color development reaction on the detection card, making the color change difference between different areas large, which makes it difficult to accurately determine the content of vitamin D, greatly increasing the error and uncertainty of the detection result; while slow drop will make the drops stay in the dropper port for a long time, and under the action of environmental factors, volatile components in the drops are easy to volatilize and lose, or dry out due to long-term exposure to air, which will change the original concentration and composition of the drops, ultimately leading to deviation of the detection result from the true value, and failing to provide reliable data support for quality evaluation and content determination of vitamin D drops.

[0005] In addition, manual operation has obvious defects in avoiding touching the detection area. During the whole dropping and detection process, it is difficult for the operator to completely avoid touching the detection area of the detection card with hands. The hands of the human being are inevitably contaminated with grease, sweat and various dust pollutants. When these substances contact the detection area, an isolation film is formed between the detection reagent and the drop, which hinders the full and effective contact between the drop and the reagent, thereby interfering with the normal chemical reaction process. Such interference can make the detection reaction unable to be completely performed or produce abnormal reaction results.

[0006] Therefore, we propose a vitamin D content determination device for vitamin D drops to solve the above problems. Content of the utility model

[0028] Embodiment: please refer to Figures 1 to 6 As shown in the figure:

[0029] The application discloses a vitamin D content measuring device for vitamin D drops, which comprises a measuring shell 1, a sliding groove 2 fixedly connected to the bottom of the inner cavity of the measuring shell 1, a touch-proof plate 3 rotatably connected to the measuring shell 1, a penetrating insertion port 4 formed in the touch-proof plate 3, a transfer plate 5 slidably connected in the sliding groove 2, a fixed groove 6 formed in the transfer plate 5, a measuring card 7 placed in the fixed groove 6, an auxiliary spring 8 fixedly connected to one side of the transfer plate 5, one end of the auxiliary spring 8 fixedly connected to the inner wall of the measuring shell 1, a supporting plate 9 fixedly connected to the upper surface of the touch-proof plate 3, an auxiliary pipe 10 arranged on one side of the supporting plate 9, a burette 11 fixedly connected to one end of the auxiliary pipe 10, a circular shell 12 fixedly connected to the side wall of the supporting plate 9, a rotating rod 13 rotatably connected to the supporting plate 9, equidistantly fixedly connected with extrusion columns 14 on the rotating rod 13, the auxiliary pipe 10 penetrating through the supporting plate 9, a main scale 15 fixedly connected to the rotating rod 13, a secondary scale 16 fixedly connected to the outer ring wall of the circular shell 12, a U-shaped shell 17 fixedly connected to the lower surface of the touch-proof plate 3, and an elastic sheet 18 fixedly connected to the U-shaped shell 17.

[0030] Wherein:

[0031] The transfer plate 5 is slidably matched with the sliding groove 2, and the insertion port 4 is matched with the burette 11.

[0032] When the touch-proof plate 3 is in a horizontal state, the insertion port 4 is located on the same vertical line with a detection burette of the measuring card 7 in the measuring shell 1.

[0033] The outermost end of the transfer plate 5 is wider than the width of the sliding groove 2, and can abut against the outer wall of the measuring shell 1, so that the auxiliary spring 8 can stabilize the transfer plate 5.

[0034] The size of the measuring card 7 is matched with the fixed groove 6, and the measuring card 7 is stable and does not move after being placed in the fixed groove 6.

[0035] The auxiliary spring 8 is mainly used for resetting the transfer plate 5.

[0036] One end of the auxiliary pipe 10 can be connected with a vitamin injection pipe or other vitamin transfer parts.

[0037] When the rotating rod 13 is rotated, the extrusion columns 14 can extrude the auxiliary pipe 10 in the rotation, so that the vitamin D drops in the auxiliary pipe 10 are transported to the burette 11.

[0038] The main scale 15 and the secondary scale 16 are matched, and can assist the operator to observe the speed of rotating the rotating rod 13, so that the transportation speed of the drops in the auxiliary pipe 10 is stable.

[0039] The elastic sheet 18 is mainly used for clamping and fixing the burette 11, so that the burette 11 is vertically and stably fixed.

[0040] Working principle:

[0041] In the initial state:

[0042] The measuring card 7 is not placed in the fixing groove 6, the auxiliary spring 8 is not stretched, and the rotating rod 13 is not rotated.

[0043] In use, first, the operator pulls out the transfer plate 5 from the measuring shell 1, and in the process of pulling out, the transfer plate 5 slides in the sliding groove 2, and the auxiliary spring 8 is stretched, at this time, the measuring card 7 is placed in the fixing groove 6, and then the hand is released, at this time, the auxiliary spring 8 restores to the original state under the action of elasticity, that is, at this time, the transfer plate 5 with the measuring card 7 placed thereon enters the measuring shell 1 under the action of the reset of the auxiliary spring 8, and thus, the placement of the measuring card 7 is completed.

[0044] Further, the vitamin D drops are injected into the auxiliary tube 10, at this time, the operator needs to rotate the rotating rod 13, at this time, the rotating rod 13 will take the equidistant fixed connection of the extrusion column 14 to extrude the auxiliary tube 10 in the circular shell 12, in the process of extruding the auxiliary tube 10, the vitamin D drops in the auxiliary tube 10 will be gradually delivered to the burette 11, and finally added to the detection area of the measuring card 7 through the burette 11; further, the main scale bar 15 and the auxiliary scale bar 16 cooperate to assist the operator to observe the speed of rotating the rotating rod 13, so as to ensure the stable delivery speed of the drops in the auxiliary tube 10;

[0045] Further, the position of the burette 11 in the plug-in interface 4 can be adjusted according to the specific use, and in this process, the elastic sheet 18 in the vertical state of the plug-in interface 4 will assist the fastening action of the moving plug-in interface 4;

[0046] Further, through the cooperation of the plug-in interface 4, the U-shaped shell 17 and the elastic sheet 18, the burette 11 can be accurately ensured to be always perpendicular to the sample dropping area of the measuring card 7 in the process of dropping, and the distance between the burette 11 and the sample dropping area is stably controlled in the ideal range through the precise positioning device; such precise vertical dropping method greatly reduces the possibility of drops spilling out of the sample dropping area, ensures that the sample can participate in the detection reaction effectively, avoids the problem of low detection result caused by sample loss, and thus significantly improves the accuracy and reliability of the detection result.

[0047] Further, through the cooperation of the rotating rod 13, the extrusion column 14, and the main and auxiliary scale bars 15 and 16, the operator can set the required dropping speed through a simple operation interface according to the detection requirements, and the rotating rod 13 is different from the existing manual dropping in that it can avoid the problem of too fast or too slow dropping speed caused by hand shaking or unskilled operation; the accurate and stable dropping speed ensures the uniformity of the distribution of the droplets in the burette 11 on the assay card 7 and the consistency of the reaction, so that the color development reaction on the assay card 7 can proceed according to the expected chemical kinetics law, avoiding the situation of excessive or insufficient local reaction caused by unstable dropping speed, thereby more accurately reflecting the content of vitamin D and improving the precision and reliability of the detection result, reducing the probability of misjudgment and error, and providing more reliable detection data for the fields of scientific research, production, and clinical diagnosis.

[0048] Further, the cooperation of the anti-touch plate 3, the transfer plate 5, and the auxiliary spring 8 can effectively protect the assay card 7 from external factors interfering with the detection result; the device is designed with a closed and independent detection space, and the anti-touch plate 3 is arranged above the assay card 7, which not only prevents the operator from accidentally touching the detection area during the dropping process, avoids the interference of oil, sweat, and other pollutants on the hands with the detection reaction, effectively reduces the risk of false negatives or deviations in the detection result, but also prevents external dust, impurities, and foreign matter from entering the detection area, ensuring the purity and stability of the detection environment; in addition, the protection can also play a certain physical protection role for the assay card 7, preventing damage to the assay card caused by accidental collision or other factors during the operation process, improving the stability and continuity of the detection process, and helping to improve the efficiency and quality of the overall detection work.
