Description

Technical Field

[0001] The utility model relates to the technical field of biological instrument auxiliary equipment, in particular to a dye dropper for uniform dyeing liquid. Background Art

[0002] In the medical field, unstained bacteria are extremely difficult to observe under a microscope due to the minimal difference in refractive index between them and their surroundings. Staining creates a sharp contrast between the bacteria and their surroundings, allowing for clear observation of their morphology, arrangement, and certain structural features, which are then used for classification and identification. A dye dropper is required to transfer the dye during staining.

[0003] Chinese patent publication number CN218823505U discloses a dye dropper. This utility model connects two liquid-dispensing needles to the same transmission pipe and then transmits them synchronously, so that the dye can be evenly distributed on both sides of the glass slide, and the dye can be evenly dripped.

[0004] During the operation of the above-mentioned equipment, it has the ability of synchronous transmission, and can fill the staining solution on both sides of the glass slide at the same time to achieve the purpose of uniform staining. The use of this equipment also has certain limitations. Since the staining specifications need to always remain at the same size, this means that during the staining process, the amount of tissue fluid must be strictly controlled. If too much or too little tissue fluid is stained, it will have an uncontrollable impact on the amount and position of the dripping. In this case, the uniformity and applicability of the staining may be affected to a certain extent, which needs to be optimized and improved. Utility Model Content

[0005] The purpose of the utility model is to provide a dye dropper for uniform dyeing liquid, so as to solve the problems raised by the above background technology.

[0028] like Figure 1-4 As shown, the present application provides a dye dripper for uniform dyeing liquid, comprising:

[0029] A mounting frame 1, with a placement plate 2 fixedly mounted on the bottom end of the mounting frame 1;

[0030] The liquid injection component 3 is fixedly inserted into the inner top of the mounting frame 1, and the inner side of the liquid injection component 3 is elastically supported by the flow control component 4. The inner bottom end of the mounting frame 1 is fixedly installed with a rotation adjustment component 5. The expansion and contraction of the flow control component 4 controls the internal flow of the liquid injection component 3;

[0031] In this embodiment: through the setting of the liquid injection component 3, it is evenly divided into three liquid injection intervals. According to actual needs, the flow control component 4 can be squeezed by rotating the adjustment component 5 to different positions, and then the number of liquid injection intervals of the liquid injection component 3 can be controlled to make the regulation performance of uniform dye dripping stronger.

[0032] Specifically, such as Figure 2 As shown, the liquid injection assembly 3 includes a liquid inlet pipe 301, and the liquid inlet pipe 301 is inserted into the inner side of the top wall of the mounting frame 1, and a rubber plug 305 is sleeved on the outer top end of the liquid inlet pipe 301;

[0033] In this embodiment, the end of the liquid inlet tube 301 allows the dye liquid to be injected, and the opening is large and easy to inject. Then the top end needs to be sealed with a rubber plug 305 before and after use to improve the protection performance.

[0034] Specifically, such as Figure 2As shown, the outer bottom end of the liquid inlet pipe 301 is fixedly connected to the annular support frame 302, and the inner part of the annular support frame 302 is provided with a sliding connection hole 303, and the bottom end of the annular support frame 302 is fixedly installed with a drip pipe 304;

[0035] In this embodiment: the bottom end of the liquid inlet pipe 301 is evenly divided into three thin tube branches, all of which are connected to the same annular support frame 302 for support. A drip tube 304 is fixed to the bottom end of each thin tube branch. The drip tube 304 can drip and dye the dye liquid. The sliding connection hole 303 opened inside the annular support frame 302 can perform sliding connection support adjustment on the flow control component 4.

[0036] Specifically, such as Figure 3 As shown, the flow control assembly 4 includes a choke rod 401, and the choke rod 401 is slidably inserted into the inner side of the sliding connection hole 303, and a leakage hole 402 is opened inside the choke rod 401, a support spring 403 is sleeved on the inner side of the outer side of the choke rod 401, and an arc-shaped push plate 404 is welded to the inner side of the choke rod 401;

[0037] In this embodiment: the blocking rod 401 is slidably connected to the inner side of the sliding connection hole 303, and then when the leakage hole 402 is aligned with the thin tube branch and the drip tube 304, it can ensure that the dye solution flows downward. After the position of the leakage hole 402 is offset, the drip tube 304 will not drip. The blocking rod 401 is pushed and supported by the arc-shaped push plate 404 as a power. After the arc-shaped push plate 404 loses pressure, it can be reset under the action of the support spring 403.

[0038] Specifically, such as Figure 4 As shown, the rotation adjustment assembly 5 includes a motor 501, and the motor 501 is fixedly mounted on the inner bottom end of the mounting frame 1, and a rotation connection block 502 is fixedly mounted on the top of the motor 501, and a turntable 503 is fixedly connected to the top of the rotation connection block 502;

The push rod 504 is divided into twelve equal parts, which are respectively in three intervals. There are three in the first interval, two in the second interval, and one in the third interval. During the rotation, the push of the arc-shaped push plate 404 can be controlled separately, which is divided into four situations: pushing all, pushing two, pushing one, and not pushing at all. The corresponding dropper 304 can be adjusted to single, two, and three drops, and the indicator disk 505 assists in the rotation direction.

[0042] The specific solution is as follows: first, place the glass slide to be stained on the placement plate 2, and then the end of the liquid inlet tube 301 can allow the dye to be injected, the opening is large and easy to inject, and then the top needs to be sealed with a rubber plug 305 before and after use, the bottom end of the liquid inlet tube 301 is evenly divided into three thin tube branches, all of which are connected to the same annular support frame 302 for support, and a drop tube 304 is fixed to the bottom end of each thin tube branch, and the drop tube 304 can drip and dye the dye, and the sliding connection hole 303 opened inside the annular support frame 302 can be used to slide and support the flow control component 4, and the flow blocking rod 401 is slidably connected to the inner side of the sliding connection hole 303, and then when the leakage hole 402 is aligned with the thin tube branch and the drop tube 304, it can ensure that the dye flows downward, and after the position of the leakage hole 402 is offset, the drop tube 304 will not drip. The choke rod 401 is driven by the arc-shaped push plate 404 as a driving force to push and support. After losing pressure, the arc-shaped push plate 404 can be reset under the action of the support spring 403.
