Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a test sample storage device. Background Technology

[0002] In the daily work of hospital laboratories, sample storage devices (such as sample transport boxes) play a crucial role in safely transporting collected sample tubes from the sampling point to the testing laboratory. Common sample storage devices typically consist of a box-like structure with a bottom shell and a top cover. The bottom shell contains a tube rack with multiple insertion holes for vertically inserting sample tubes. Once the top cover is closed, the entire device is moved.

[0003] However, test tubes may break during transportation due to impact, pressure, or inherent defects. Once a test tube breaks, the liquid sample inside will leak out. Since the bottom of the test tube socket in existing devices is usually open or simply interconnected, the leaked material can flow uncontrollably to the bottom of the casing, contaminating the outer walls of other intact test tubes, the test tube rack, and the inner walls of the casing, causing widespread cross-contamination. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a sample storage device for testing.

[0005] The technical solution adopted by this utility model is as follows: This application provides a test sample storage device for storing test tubes, including a bottom shell and a top cover hinged on one side. A test tube rack is provided inside the bottom shell. A plurality of test tube insertion holes are evenly arranged on the test tube rack, and an isolation cylinder extends from the bottom of each test tube insertion hole. A conical guide funnel is provided at the bottom of the isolation cylinder. A through hole is opened in the center of the conical guide funnel. Water-absorbing cotton is provided inside the bottom shell below the through hole. The inner diameter of the test tube insertion hole is larger than the inner diameter of the isolation cylinder. The inner diameter of the isolation cylinder is larger than the outer diameter of the test tube. An elastic positioning ring is provided inside the test tube insertion hole. A plurality of vertical grooves are provided on the inner peripheral wall of the elastic positioning ring.

[0006] In some embodiments, a flow guide plate is also included. The flow guide plate is disposed above the test tube rack, and a tapered flow guide portion with a larger upper part and a smaller lower part is provided on it corresponding to each test tube insertion hole. The lower inner diameter of the tapered flow guide portion is larger than the inner diameter of the elastic positioning ring and smaller than the outer diameter of the elastic positioning ring.

[0007] In some embodiments, the bottom shell has an inwardly protruding stepped portion, the test tube rack includes a plate portion, the test tube insertion hole is opened on the plate portion, the plate portion abuts against the stepped portion, the guide plate abuts against the upper part of the plate portion, and a snap-fit ​​structure is provided between its side wall and the inner wall of the bottom shell.

[0008] In some embodiments, the guide plate is provided with a disassembly / removal part, which is used by a user to grab and disassemble the guide plate.

[0009] In some embodiments, the inner sidewall of the conical guide bucket is uniformly provided with a plurality of guide grooves, which are connected to the through holes.

[0010] In some embodiments, the absorbent cotton is provided with a conical positioning groove coaxially corresponding to each test tube insertion hole.

[0011] In some embodiments, a pressure plate is provided on the upper cover, the pressure plate rotates with the upper cover, and an elastic positioning part is provided on it corresponding to each test tube insertion hole. When the upper cover is closed, the elastic positioning part abuts against the upper end of the test tube to form a positioning.

[0012] In some embodiments, the elastic positioning part is a protrusion adapted to the test tube, or a protrusion with a positioning groove provided on the protrusion, and the opening end of the positioning groove is provided with a tapered guide that gradually expands toward the bottom shell.

[0013] The beneficial effects of this invention are as follows: By setting an independent isolation cylinder and a conical guide funnel with a through hole at the bottom below each test tube insertion hole, and placing absorbent cotton at the bottom, this invention constructs an independent, physically isolated leakage collection channel for each test tube. When a single test tube breaks, the leaked liquid is confined in its corresponding isolation cylinder and guided through the conical guide funnel to the through hole, and finally absorbed by the absorbent cotton directly below it, thus minimizing cross-contamination.

[0018] It should be noted that the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are only used to distinguish different components and should not be construed as limiting the embodiments of this application.

[0019] It should be noted that the terms "installation," "setup," "equipped with," "connection," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral structures; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or internal connections between two devices, components, or parts.

[0020] It should be noted that the terms "in some embodiments," "exemplarily," and "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "in some embodiments," "exemplarily," or "for example" should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "in some embodiments," "exemplarily," and "for example" is intended to present the relevant concepts in a specific manner, meaning that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of this application.

[0021] Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] Regarding the accompanying drawings of this application, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not necessarily drawn to scale.

[0023] During sample transport, if a single sample tube breaks, the leaked material can easily spread within the storage device, causing cross-contamination and biosafety risks.

[0024] Based on the above issues, such as Figures 1 to 4 As shown, this utility model provides a sample storage device for storing test tubes 800. It includes a bottom shell 100 and a top cover 200 hinged together on one side. A test tube rack 300 is disposed inside the bottom shell 100. The test tube rack 300 has a plurality of test tube insertion holes 320 evenly distributed on it for inserting test tubes 800. A downwardly protruding isolation cylinder 400 integrally extends from the bottom of each test tube insertion hole 320. A conical guide hopper 410 is connected to the bottom of the isolation cylinder 400. A through hole 411 is formed in the center of the conical guide hopper 410. On the inner bottom wall of the bottom shell 100, directly below the through hole 411, there is a water-absorbing cotton 500. The inner diameter of the test tube insertion hole 320 is larger than the inner diameter of the isolation cylinder 400 below it, and the inner diameter of the isolation cylinder 400 is slightly larger than the outer diameter of the standard test tube 800. An elastic positioning ring 600 is also embedded in the inner wall of the test tube insertion hole 320 to provide radial clamping force after the test tube 800 is inserted to prevent the test tube 800 from shaking during transportation. The inner peripheral wall of the elastic positioning ring is provided with several vertical grooves so that the liquid leaking from above can flow into the isolation cylinder 400 through the vertical grooves.

[0025] After each test tube 800 is inserted into the test tube socket 320, the body of the test tube 800 is located in the upper test tube socket 320, and its lower end extends into the corresponding isolation cylinder 400 below. If the test tube 800 breaks, the leaked liquid will first be confined within its dedicated isolation cylinder 400 and will not overflow laterally into adjacent isolation spaces. Subsequently, the liquid flows to the conical guide bucket 410 under the action of gravity, and after being collected by its conical surface, drips from the central through hole 411, and is finally absorbed by the absorbent cotton 500 directly below. Since each isolation unit (i.e., the isolation cylinder 400, the conical guide bucket 410, and the through hole 411) is vertically aligned and independent in space, cross-contamination is effectively avoided.

[0026] In some embodiments, a guide plate 700 is also provided above the test tube rack 300. The guide plate 700 has a tapered guide portion 710, wider at the top and narrower at the bottom, corresponding to each test tube insertion hole 320. The lower inner diameter of the tapered guide portion 710 is designed to be larger than the inner diameter of the elastic positioning ring 600 and smaller than the outer diameter of the elastic positioning ring 600. With this configuration, when the guide plate 700 is in place, the lower end face of its tapered guide portion 710 will cover the connection between the elastic positioning ring 600 and the test tube insertion hole 320. Even if liquid flows down the outer wall from the test tube opening, it will be guided by the tapered guide portion 710 and flow directly into the isolation cylinder 400 below, without contaminating the upper surface of the test tube rack 300.

[0027] In some embodiments, the inner sidewall of the bottom shell 100 protrudes inward to form a stepped portion 110, and the test tube rack 300 includes a plate portion 310 on which all test tube insertion holes 320 are formed. During installation, the plate portion 310 is placed directly on and abuts against the stepped portion 110, and the guide plate 700 is placed above the plate portion 310. It is detachably connected through a snap-fit ​​structure, such as the cooperation of an elastic hook and a slot, between its sidewall and the inner wall of the bottom shell 100, thus making the test tube rack 300 easy to assemble and disassemble.

[0028] The height of the stepped portion 110 is set according to requirements, preferably as close as possible to the opening on the bottom shell 100, so that the isolation unit can cover the entire test tube as much as possible.

[0029] In some embodiments, the guide plate 700 is provided with a disassembly part at its edge. The disassembly part may be a raised handle, a groove or a perforation, providing a point of leverage for the user to easily pick up, put down and clean the guide plate 700.

[0030] In some embodiments, a plurality of guide grooves 412 are uniformly provided circumferentially on the inner wall of the conical guide bucket 410. The upper end of the guide groove 412 extends to near the top of the conical guide bucket 410, and the lower end communicates with the central through hole 411, which can guide the liquid to flow more quickly and thoroughly to the through hole 411 and reduce the adhesion of liquid on the conical surface.

[0031] In some embodiments, the upper surface of the absorbent cotton 500 is embossed or cut to form a conical positioning groove 510 corresponding to the central axis position of each test tube insertion hole 320, thereby increasing the absorption surface of the absorbent cotton 500.

[0032] In some embodiments, a pressure plate 210 is provided on the inner side of the upper cover 200. The pressure plate 210 rotates together with the upper cover 200, and an elastic positioning part 220 is provided on the pressure plate 210 corresponding to the position of each test tube insertion hole 320. When the upper cover 200 is closed, the elastic positioning part 220 moves downward and abuts against the upper end of the corresponding test tube 800, such as a test tube cap, thereby forming axial positioning and preventing the test tube 800 from falling out of the test tube insertion hole 320 during bumps.

[0033] In some embodiments, the elastic positioning part 220 can be implemented in two specific forms. The first is a simple protrusion 221 that adapts to the shape of the upper end of the test tube 800, which presses the test tube by its elastic deformation. The second is to open a positioning groove 222 on the protrusion 221. The opening end of the positioning groove 222 is provided with a tapered guide part 223 that gradually expands towards the bottom shell 100. When the top cover 200 is closed, the tapered guide part 223 can automatically guide the upper end of the test tube 800 into the positioning groove 222, making the positioning more accurate and stable.
