Description

Technical Field

[0001] This utility model belongs to the technical field of sample collection devices, and in particular relates to a micro-collection device for aquatic molecular samples. Background Technology

[0002] Aquatic molecular samples refer to sample materials obtained from aquatic animals (such as fish, shrimp, crabs, and shellfish) for molecular biology research. These sample materials can be divided into tissue samples (such as heart, liver, spleen, pancreas, gonads, intestines, muscle, and brain tissue) and cell samples (such as PBMCs and single-cell suspensions). Through these samples, researchers can conduct various molecular biology studies, including single-cell sequencing, genetic analysis, and disease mechanism research, to gain a deeper understanding of the growth, development, genetic evolution, and disease occurrence processes of aquatic animals, providing an important theoretical foundation and technical support for the healthy and sustainable development of aquaculture.

[0003] Existing micro-sample collection devices for aquatic molecular samples tend to cause samples to stick to the inner wall of the sampling tube after collection, making it inconvenient to remove the samples and thus causing inconvenience to aquatic molecular biology research.

[0004] Therefore, this invention provides a device for collecting trace amounts of aquatic molecular samples to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a device for collecting trace amounts of aquatic molecular samples to address the shortcomings of existing technologies.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0007] A micro-collection device for aquatic molecular samples includes a mounting plate, a sample arrangement structure installed at the bottom of the mounting plate, and a sampling tube installed on the sample arrangement structure.

[0008] The sampling structure includes an ejection mechanism and two symmetrically mounted support shells at the bottom of the mounting plate. A T-shaped slider connected to the outer wall of the sampling cylinder is slidably mounted inside the support shell. The sampling structure also includes a threaded rod and a worm gear rotatably mounted inside the mounting plate via bearings. The lower part of the threaded rod is threadedly engaged with the T-shaped slider, and the upper part of the threaded rod is equipped with a worm wheel that engages with the worm gear transmission. One end of the worm gear passes through the mounting plate and extends to the outside, and is equipped with a crank handle.

[0009] Furthermore, the ejection mechanism includes: a vertical rod fixed at the center of the bottom of the mounting plate, an ejection circular plate installed at the bottom end of the vertical rod, and the outer wall of the ejection circular plate being slidably connected to the inner wall of the sampling cylinder.

[0010] Furthermore, the mounting plate has an internal cavity for mounting the worm gear and worm. The lower end of the threaded rod passes through the mounting plate and extends into the inner cavity of the left support shell, and is rotatably connected to the bottom of the inner cavity of the left support shell via a bearing.

[0011] Furthermore, a handle is installed at the top center of the mounting plate, and the lower end of the sampling tube is a spike.

[0012] Furthermore, a cleaning structure is installed at the bottom of both of the aforementioned support shells;

[0013] The cleaning structure includes an internally threaded sleeve installed on the front and rear side walls of the support shell. The internally threaded sleeve is fixedly installed with an installation ring by a fixing bolt, and a sponge ring is installed at the bottom of the installation ring.

[0014] Furthermore, the outer wall of the mounting ring is provided with connecting ears for connection with fixing bolts, and the inner diameter of the sponge ring is adapted to the outer diameter of the sampling cylinder.

[0015] The micro-collection device for aquatic molecular samples provided by this utility model has the following advantages compared with the prior art:

[0016] By setting up a sampling structure, the rotation of the threaded rod moves the T-shaped slider upward, and the T-shaped slider moves the sampling cylinder upward synchronously. Under the reaction force, the ejector plate pushes the sample in the sampling cylinder downward, avoiding the problem that aquatic samples tend to stick to the inner wall of the sampling cylinder after sampling in existing aquatic molecular sample micro-collection devices, making it inconvenient to remove the samples. This provides convenience for aquatic molecular biology research. Attached Figure Description

Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments:

[0024] Example 1

[0025] refer to Figure 1-3 As shown, this utility model provides a micro-collection device for aquatic molecular samples, including a mounting plate 1, a sample arrangement structure 2 installed at the bottom of the mounting plate 1, and a sampling tube 3 installed on the sample arrangement structure 2.

[0026] The sampling structure 2 includes an ejection mechanism and two support shells 21 symmetrically installed at the bottom of the mounting plate 1. A T-shaped slider 23 connected to the outer wall of the sampling cylinder 3 is slidably installed in the inner cavity of the support shell 21. The sampling structure 2 also includes a threaded rod 24 and a worm gear 26 rotatably installed in the mounting plate 1 via bearings. The lower part of the threaded rod 24 is threadedly engaged with the T-shaped slider 23, and the upper part of the threaded rod 24 is equipped with a worm wheel 25 that is driven by the worm gear 26. One end of the worm gear 26 passes through the mounting plate 1 and extends to the outside, and is equipped with a crank handle 261.

[0027] In a preferred embodiment, the ejection mechanism includes: a vertical rod 221 fixed at the bottom center of the mounting plate 1, an ejection circular plate 22 installed at the bottom end of the vertical rod 221, and the outer wall of the ejection circular plate 22 being slidably connected to the inner wall of the sampling cylinder 3.

[0028] In a preferred embodiment, the mounting plate 1 has an internal receiving groove 11 for mounting the worm gear 25 and the worm 26. The lower end of the threaded rod 24 passes through the mounting plate 1 and extends into the inner cavity of the left support shell 21, and is rotatably connected to the bottom of the inner cavity of the left support shell 21 through a bearing.

[0029] In a preferred embodiment, a handle 4 is installed at the top center of the mounting plate 1, and the lower end of the sampling tube 3 is a spike 31. With the spike 31, the user can easily insert the handle 4 and aim the spike 31 at the aquatic product to perform sampling.

[0030] In use, the user drives the crank 261 to rotate the worm gear 26, which in turn rotates the worm wheel 25. The worm wheel 25, in turn, rotates the threaded rod 24 synchronously on the mounting plate 1 and the left support shell 21. The threaded rod 24 moves the left T-shaped slider 23 upward, and the T-shaped slider 23 moves the sampling cylinder 3 upward synchronously. Since the ejector plate 22 is fixed, under the reaction force, the ejector plate 22 moves downward relative to the inner wall of the sampling cylinder 3. The ejector plate 22 pushes the sample in the sampling cylinder 3 downward, avoiding the problem in existing aquatic molecular sample micro-collection devices where aquatic samples easily stick to the inner wall of the sampling cylinder 3 after sampling, making it inconvenient to remove the samples. This allows for easy removal of the sample from the sampling cylinder 3, providing convenience for aquatic molecular biology research.

[0031] Example 2

[0032] refer to Figure 4 As shown, unlike Example 1, the existing aquatic molecular sample micro-collection device does not have the function of cleaning the outer wall of the sampling tube 3, resulting in poor cleanliness of the collection device. Therefore, a cleaning structure 5 is installed at the bottom of the two support shells 21.

[0033] The cleaning structure 5 includes an internally threaded sleeve 51 installed on the front and rear side walls of the support shell 21. The internally threaded sleeve 51 is fixedly installed with an installation ring 53 by a fixing bolt 52. A sponge ring 54 is installed at the bottom of the installation ring 53.

[0034] In a preferred embodiment, the outer wall of the mounting ring 53 is provided with a connecting lug 531 that connects to the fixing bolt 52, and the inner diameter of the sponge ring 54 is adapted to the outer diameter of the sampling cylinder 3.

[0035] During use, the threaded rod 24 moves upward with the left T-shaped slider 23, and the T-shaped slider 23 moves upward with the sampling cylinder 3. At the same time, the sponge ring 54 remains stationary and moves downward relative to the sampling cylinder 3. The sponge ring 54 wipes the contaminants on the outer wall of the sampling cylinder 3. The sponge itself has good water absorption and decontamination ability, which realizes the cleaning of the outer wall of the sampling cylinder 3. This avoids the problem that the existing aquatic molecular sample micro-collection device does not have the function of cleaning the outer wall of the sampling cylinder 3, resulting in poor cleanliness of the collection device, and improves the overall cleanliness of the collection device.

[0036] The use of the internal threaded sleeve 51, the fixing bolt 52 and the mounting ring 53 facilitates the disassembly, cleaning and replacement of the sponge ring 54, allowing the sponge ring 54 to maintain good cleaning ability.
