Description

Technical Field

[0001] This utility model relates to the technical field of medical tools, and in particular to a split-type sampler with snap-fit ​​connection. Background Technology

[0002] As is well known, blood sample collection is fundamental to various biological experiments. Therefore, the tools used for blood sample collection are particularly important. Currently, most samplers consist of a sampler and a cap. The sampler can be used for quantitative blood collection from specific sites such as the hand or foot for testing, or for quantitative fluid collection in the laboratory. After collection, the sampler is inserted into a pre-set sample bottle for storage. However, the connection between the sample storage sleeve and the sampler is currently achieved through an interference fit, where the sampler is snapped into the sample storage sleeve. This method not only makes it difficult for users to determine whether the sample storage sleeve and the sampler are tightly connected, thus increasing the assembly time, but also risks damage to the sample storage sleeve or the sampler due to the interference fit, contaminating the sample collected by the sampler.

[0003] Therefore, based on the above-mentioned technical problems, this application proposes a split-type sampler with snap-fit ​​connection that is easy to assemble and has a stable connection. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a split sampler with snap-fit ​​connection that is easy to assemble and has a stable connection.

[0005] To achieve the above objectives, this utility model provides a split-type sampler with snap-fit ​​connection, comprising a sampler body, a sampler cover and a sample storage sleeve containing buffer solution that can be assembled onto the sampler body. The sampler cover and the sample storage sleeve are respectively disposed at both ends of the sampler body. The sampler cover includes a cover body and a puncture tip disposed on the cover body. A blocking ring is disposed on the outer wall of the sampler body. The sampler cover is fitted onto the sampler body and abuts against one side of the blocking ring. The sample storage sleeve is fitted onto the sampler body and abuts against the other side of the blocking ring. The feature is that it further includes a detachable sampling tube installed on the sampler body. Two snap-fit ​​parts for snapping the sampling tube are symmetrically arranged on the sampler body. A snap-fit ​​protrusion is disposed at the top of the sampling tube. As the sampling tube moves toward the snap-fit ​​part of the sampler body, the snap-fit ​​part snaps against one side of the snap-fit ​​protrusion.

[0006] Furthermore, at least one positioning ring for engaging the sampler body is protruding from the upper middle part of the inner wall of the sample storage sleeve. A positioning groove is provided around the outer wall of the sampler body on the side where the sample storage sleeve is installed. The positioning ring and the positioning groove are interlocked to prevent the sampler body from falling out of the sample storage sleeve.

[0007] Furthermore, a limiting boss is formed protruding from the bottom of the sampler body, which is engaged with one side of the snap-fit ​​part and the other side of the limiting boss and the snap-fit ​​boss.

[0008] Furthermore, the bottom of the sampler body has a protruding limiting part to prevent the sampling tube from over-fitting, and the inner wall of the sampling tube has a protruding stop part to cooperate with the limiting part. As the snap-fit ​​part and the fastening boss are fastened to each other, the limiting part and the stop part stop and abut against each other.

[0009] Furthermore, the sampler body is formed with an exchange section that runs horizontally through the sample and is used to bring the sample into contact with the buffer solution.

[0010] Furthermore, the sampler has a vertically penetrating suction hole and a liquid outlet hole formed at both ends, wherein the suction hole and the liquid outlet hole are respectively connected to the exchange part; the suction hole and the liquid outlet hole are arranged coaxially.

[0011] The present invention adopts the above-described solution, and its beneficial effects are as follows:

[0012] Easy assembly: By designing the sampling tube into separate parts, the sampling tube can be flexibly disassembled from the sampler body, making it easier to remove the sampling tube after sample collection, thereby saving the time required for the detection process.

[0013] Secure connection: By improving and optimizing the connection method between the sampling tube and the sampler body, a snap-fit ​​connection is adopted to ensure the stability of the connection and prevent the sampling tube from falling off the sampler body and contaminating the sample collected by the sampling tube.

Detailed Implementation

[0019] To facilitate understanding of this utility model, a more complete description of it is provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0020] See appendix Figure 1 As shown, in this embodiment, a split-type sampler with a snap-fit ​​connection includes a sampler body 1, a sampler cover 2 that can be assembled onto the sampler body 1, and a sample storage sleeve 3 containing buffer solution. The sampler cover 2 and the sample storage sleeve 3 are respectively disposed at both ends of the sampler body 1. The sampler cover 2 includes a cover body 21 and a puncture tip 22 disposed on the cover body 21. A blocking ring 13 is disposed on the outer wall of the sampler body 1. The sampler cover 2 is sleeved on the sampler body 1 and abuts against one side of the blocking ring 13. The sample storage sleeve 3 is sleeved on the sampler body 1 and abuts against the other side of the blocking ring 13. The sampler body 1 is characterized by further including: The sampler includes a detachable sampling tube 11 mounted on the sampler body 1. Two snap-fit ​​parts 15 are symmetrically arranged on the sampler body 1 for snapping the sampling tube 11. The top end of the sampling tube 11 is provided with a snap-fit ​​protrusion 113. As the sampling tube 11 moves toward the snap-fit ​​part 15 of the sampler body 1, the snap-fit ​​part 15 and one side of the snap-fit ​​protrusion 113 snap together, thereby relatively limiting the sampling tube 11 to be installed on the sampler body 1 in the vertical direction. In addition, when the sample storage sleeve 3 is sleeved on the sampler body 1, the sampler can be securely snapped onto the sampler body 1 and the integrity of the sample taken by the sampler is ensured by the isolation of the sample storage sleeve 3.

[0021] See appendix Figure 3 As shown, in this embodiment, a limiting boss 111 protrudes from the bottom of the sampler body 1, which engages with one side of the snap-fit ​​part 15 and the fastening boss 113, while the limiting boss 111 and the fastening boss 113 abut against each other. A limiting part 12 protrudes from the bottom of the sampler body 1 to prevent over-fitting of the sampling tube 11, and a stop part 112 protrudes from the inner wall of the sampling tube 11 to engage with the limiting part 12. The limiting part 12 and the stop part 112 abut against each other, with the snap-fit ​​part 15 engaging with the fastening boss 113, and the limiting part 12 abutting against each other. Specifically... When the snap-fit ​​part 15 and the snap-fit ​​protrusion 113 of the sampling tube 11 are snapped together, the limiting protrusion 111 of the sampler body 1 and the other side of the snap-fit ​​protrusion 113 abut against each other, and the limiting part 12 of the sampler body 1 and the stop part 112 of the sampling tube 11 abut against each other, so that the sampling tube 11 is more securely installed on the sampler body 1, preventing the sampling tube 11 from being over-fitted with the sampler body 1 and damaging the sampling tube 11 or the sampler body 1; at the same time, it is easier for the sampling tube 11 to be better positioned and assembled on the sampler body 1, saving the assembly time required.

[0022] In this embodiment, referring to Figure 1, the sampler body 1 has an exchange section 16 formed on it, which runs horizontally through the sample and is used to bring the sample into contact with the buffer solution. At both ends of the sampler, a suction hole 17 and an outlet hole 18 are formed, respectively, running vertically through the sampler body. The suction hole 17 and the outlet hole 18 are connected to the exchange section 16. The suction hole 17 and the outlet hole 18 are arranged coaxially. Through the cooperation between the exchange section 16 and the suction hole 17 on the sampler body 1, the buffer solution and the sample are mixed, facilitating subsequent analysis of the sample and ensuring the airtightness of the reservoir tube. Through the cooperation between the exchange section 16 and the suction hole 17 on the sampler body 1, the buffer solution containing the mixed sample in the reservoir tube is output to the outside.

[0023] Specifically, when it is necessary to take out the sample for use, the split sampler in this embodiment is inverted, and the sample on the sampling tube 11 is transported along the suction hole 17 through the exchange section 16, so that the sample is mixed with the buffer solution in the storage tube for subsequent use; secondly, by pressing the body of the storage tube, the buffer solution of the mixed sample is output to the outside through the exchange section 16 along the outlet hole 18.

[0024] Further, referring to Figure 2, at least one, preferably two, positioning rings 31 protrude from the upper middle part of the inner wall of the sample storage sleeve 3 for engaging the sampler body 1. A positioning groove 14 is provided around the outer wall of the sampler body 1 on the side where the sample storage sleeve 3 is mounted. The positioning rings 31 and the positioning groove 14 interlock to prevent the sampler body 1 from falling out of the sample storage sleeve 3, thereby ensuring that the sample storage sleeve 3 is securely mounted on the sampler body 1. The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any modifications or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, based on the disclosed technical content, are equivalent embodiments of this utility model. Therefore, all equivalent changes made based on the concept of this utility model without departing from its technical solution should be covered within the protection scope of this utility model.
