Description

Technical Field

[0001] This utility model relates to the field of sample preservation device technology, specifically a sample preservation device for carbapenem-resistant Enterobacteriaceae. Background Technology

[0002] Carbapenem-resistant Enterobacteriaceae samples are crucial biomaterials for microbial detection, resistance mechanism research, and clinical diagnosis and treatment. The quality of their preservation and transport directly affects the accuracy of test results and sample integrity. These samples are typically contained in test tubes and require sample boxes for storage and transport. However, bumps and shaking during transport can easily lead to test tube collisions, loosening of caps, and even sample leakage. Therefore, a fixed structure is necessary to limit and protect the test tubes.

[0003] However, existing sample box tube fixation structures mostly use designs such as clamping, foam padding, or airbag covering. To achieve a stable effect, additional locking, inflation, or filling operations are often required. This is not only cumbersome and inefficient, but improper operation may also affect the fixation effect, further increasing the workload of staff. It cannot meet the needs of efficient and convenient sample transportation and preservation in clinical and laboratory settings. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a device for preserving carbapenem-resistant Enterobacteriaceae resistance gene samples.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A device for preserving carbapenem-resistant Enterobacter spp. resistance gene samples includes a box with a partition at the top opening;

[0007] At least one placement component, each of the placement components comprising:

[0008] An elliptical ring is disposed through the partition plate, and an elastic pad is provided on its inner wall. An inclined circular hole is provided on the elastic pad.

[0009] An inclined plate is fixed to the bottom of the elliptical ring, and its bottom end extends downward at an inclination toward the axis of the elliptical ring. A guide portion is provided on one side of the inclined plate, and the guide portion faces the downward opening direction of the circular hole.

[0010] During the process of inserting the sample tube obliquely into the round hole, the bottom end of the test tube is stopped by the guide part and slides along the axial direction of the guide part, forming a deflection movement trend that is horizontally opposite to the insertion direction. The elastic pad is squeezed by the deflection force and generates compression deformation, so that the two sides of the round hole at the inlet and outlet positions are deformed and compressed to form a bidirectional clamping structure for the test tube.

[0011] Preferably, the angle between the axis of the circular hole and the vertical direction is 20° to 30°, and the angle between the guide portion and the axis of the circular hole is greater than 120°.

[0012] Preferably, the guide portion is composed of multiple alternating upper and lower inclined surfaces, the upper inclined surfaces facing the circular hole and having a first inclination, the lower inclined surfaces facing away from the circular hole and having a second inclination, the second inclination being greater than the first inclination.

[0013] Preferably, the placement assembly further includes a limiting ring, which is located at the bottom end of the inclined plate and coaxially arranged with the elastic pad. When the bottom end of the test tube is inserted into the limiting ring, the test tube is in a vertical position.

[0014] Preferably, the inner wall of the limiting ring is provided with a flexible ring, and the inner wall of the flexible ring is smooth to reduce the contact friction between it and the test tube.

[0015] Preferably, the bottom end of the guide portion points towards the inner wall of the flexible ring, and the two transition smoothly.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: the placement component can guide the test tube to form a deflection trend when it is inserted at an angle, and the elastic pad will generate directional deformation, automatically forming a bidirectional clamping structure for the test tube. No additional locking operation is required, and the insertion is fixed, which greatly improves the convenience of operation, effectively resists the bumps during transportation, avoids violent shaking or collision of the test tube, ensures the integrity of the sample, and meets the needs of clinical and laboratory efficient and safe sample preservation and transportation.

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] Example

[0027] like Figures 1-6 As shown, a sample preservation device for carbapenem-resistant Enterobacteriaceae includes a box body 1 with a partition 11 at the top opening. The box body 1 provides the installation base and protective shell for the whole device, and the partition 11 serves as a fixed carrier for placing components 2, realizing the orderly arrangement of multiple placement components 2, while limiting the vertical space for inserting test tubes.

[0028] At least one placement component 2, and there are multiple placement components 2 arranged in a rectangular array, each placement component 2 including:

[0029] An elliptical ring 21 is disposed through the partition 11, and an elastic pad 211 is provided on its inner wall. An inclined circular hole 212 is provided on the elastic pad 211. The angle between the axis of the circular hole 212 and the vertical direction is 20° to 30°. The inclined circular hole 212 provides an oblique insertion path for the test tube and is adapted to the subsequent deflection and guiding action.

[0030] An inclined plate 23 is fixed to the bottom of an elliptical ring 21, and its bottom end extends downward at an inclination toward the axis of the elliptical ring 21. A guide portion is provided on one side of the inclined plate 23, which faces the downward opening of the circular hole 212. The angle between the guide portion and the axis of the circular hole 212 is greater than 120°.

[0031] The guide section is composed of multiple alternating upper inclined surfaces 231 and lower inclined surfaces 232. The upper inclined surfaces 231 face the circular hole 212 and have a first slope, while the lower inclined surfaces 232 face away from the circular hole 212 and have a second slope, which is greater than the first slope. When the user inserts the test tube, its bottom end will slide on the surface of multiple upper inclined surfaces 231 with smaller slopes, making it easier to insert. When the user pulls out the test tube, its bottom end will successively abut against the lower inclined surfaces 232. The slope design increases the resistance to pulling out the test tube, making the pulling out process more stable.

[0032] The placement component 2 also includes a limiting ring 22, which is located at the bottom of the inclined plate 23 and coaxially arranged with the elastic pad 211. When the bottom of the test tube is inserted into the limiting ring 22, the test tube is in a vertical position. The inner wall of the limiting ring 22 is provided with a flexible ring 221, and the inner wall of the flexible ring 221 is smooth to reduce the contact friction between it and the test tube. The bottom of the guide part points to the inner wall of the flexible ring 221, and the two are smoothly transitioned. The flexible ring 221 realizes the flexible positioning of the bottom of the test tube, and the smooth inner wall reduces frictional damage when the test tube is inserted or removed, while also helping the test tube to finally maintain a vertical position. The smooth transition design between the guide part and the flexible ring 221 ensures that the test tube can smoothly enter the limiting ring 22 after deflection, avoids jamming, and further improves the smoothness of operation.

[0033] Please see Figures 3 to 5 When the sample tube is inserted along the inclined direction of the circular hole 212, the bottom of the tube will first contact the guide part of the inclined plate 23 and be stopped by it. With the continuous downward insertion force, the bottom of the tube will slide continuously and alternately along the surface of the guide part. During this process, the inclination angle of the guide part will generate a lateral guiding force on the bottom of the tube, causing the tube to form a deflection movement trend opposite to the initial insertion direction. This deflection trend will be converted into a lateral squeezing force on the elastic pad 211, causing the elastic pad 211 to undergo directional compression deformation. Specifically, the two side walls opposite to the inlet and outlet positions of the circular hole 212 are elastically compressed towards the tube and form a reverse force, ultimately forming a two-way clamping structure for the tube. The symmetrical squeezing force on both sides achieves stable positioning of the tube, avoiding violent shaking and collision during the transport and storage of the tube, and preventing the cap from loosening or the sample from leaking, thus ensuring the integrity of the sample.

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
