Description

Technical Field

[0001] The present invention relates to the field of medical auxiliary equipment, and in particular to a clinical trial test tube rack capable of preventing biological contamination. Background Art

[0002] In the field of clinical testing, biocontamination control of test tube samples is a core link that affects the accuracy of results. Currently, conventional test tube racks only provide simple storage functions and lack active anti-contamination mechanisms. Samples are at significant risk of exposure to environmental aerosols or cross-contamination during storage and testing. Laboratory personnel need to frequently manually seal test tube caps or transfer samples, which is a cumbersome process and increases the chance of contamination. Especially when dealing with highly infectious samples, existing technologies make it difficult to achieve a balance between convenient storage and reliable bioprotection. Although ultraviolet sterilization is used, it is usually independent of the sample storage device and cannot continuously and efficiently irradiate the key interface areas of the test tubes during storage intervals.

[0003] There is an urgent need for a dedicated solution that combines convenient operation, dynamic sealing and in-place sterilization, so a bio-contamination-proof clinical trial test tube rack was developed. Summary of the Invention

[0004] In order to overcome the problem that existing technologies are difficult to strike a balance between convenient access and reliable biological protection, although ultraviolet sterilization is used, it is usually independent of the sample storage device and cannot continuously and efficiently irradiate the key interface areas of the test tubes during storage intervals. The present invention provides a clinical trial test tube rack that is resistant to biological contamination.

[0005] The technical implementation scheme of the present invention is: A clinical trial test tube rack for preventing biological contamination, comprising: Mounting rack; a sliding plate, the sliding plate being slidably connected within the mounting frame; a rubber plate mounted on the sliding plate; a test tube placed between the sliding plate and the rubber plate; A rotating plate, the rotating plate being rotatably mounted on the mounting frame; a sterilization lamp, the sterilization lamp being mounted on the rotating plate; Locking components, the locking components are installed on the left and right sides of the upper part of the mounting frame; a first spring, the first spring being mounted between the locking assembly and the mounting bracket; An inclined plate, the inclined plate being mounted on the lower inner side of the mounting frame; a first connecting member, the first connecting member being mounted on the lower sides of the left and right portions of the sliding plate; A carrying plate is slidably connected between the first connecting members. The carrying plate can be pushed by the rotating plate to move upward along the inclined plate to push the test tube.

[0006] In a preferred embodiment of the present invention, the locking assembly includes: A mounting frame, the mounting frame being mounted on the left and right sides of the upper portion of the mounting frame; A latch, the latch being slidably connected to the mounting frame; A guide block is installed on the inner side of the clamping bolt and is clamped with the rotating plate.

[0007] In a preferred embodiment of the present invention, it also includes: a first mounting plate, the first mounting plate being mounted on the front side of the mounting frame; a second mounting plate, the second mounting plate being mounted on the rear side of the mounting frame; a guide rod, the guide rod being installed between the first mounting plate and the second mounting plate and being slidably connected to the sliding plate; A second spring is installed between the sliding plate and the first mounting plate and is sleeved on the corresponding guide rod.

[0008] In a preferred embodiment of the present invention, it also includes: Mounting blocks, the mounting blocks being arranged on the left and right sides of the lower portion of the mounting frame; second connecting members, each of which is mounted on the corresponding mounting block; The gripping blocks are installed on the lower side of the corresponding second connecting member and are in contact with the ground.

[0009] In a preferred embodiment of the present invention, it also includes: A light-collecting plate, the light-collecting plate being rotatably connected to the rotating plate; A limit block is installed on the rotating plate and is used to limit the flipping of the focusing plate.

[0010] In a preferred embodiment of the present invention, a rubber strip is further included, which is installed at the hinge between the rotating plate and the mounting frame. In a preferred embodiment of the present invention, the rotating plate is an L-shaped structure, which can push the sliding plate.

[0011] In a preferred embodiment of the present invention, a handle is further included, and the handle is installed on the rotating plate.

[0012] In a preferred embodiment of the present invention, an annular boosting block is provided on the outer side of each of the clamping bolts.

[0013] In a preferred embodiment of the present invention, the second connecting member is a bent structure.

[0014] By adopting the above technical solution, the present invention has the following advantages compared with the prior art: 1. The present invention uses the flipping of the L-shaped rotating plate to drive a single action, linking the sliding plate to expand the clamping space and synchronously control the test tube with the carrier plate. The operator only needs to flip the lever to instantly release the fixed constraint and safely obtain the test tube, avoiding repeated removal of the lid or contact with the sample area, significantly reducing contamination caused by improper operation. When closed, the spring-driven automatic reset combined with the rotating plate mechanically locks the carrier plate and presses the rubber plate to form a wrap-around seal, ensuring that the test tube is isolated from external contamination in the storage position. Its precise mechanical linkage structure truly realizes fast and safe access with one hand and one step.

[0015] 2. The ultraviolet lamp integrated in the rotating plate of the present invention cooperates with the adjustable focusing plate to continuously and intensively disinfect the core area of ​​the test tube in the sealed storage state, directly killing potential contaminants at the mouth. The elastic clamping, bottom lifting grip and rubber buffer work together to ensure the stability of the test tube and the equipment, eliminating the risk of displacement. This design integrates biosafety control throughout the entire storage and retrieval process, greatly improving the reliability of clinical sample testing. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A clinical trial test tube rack to prevent biological contamination, such as Figures 1-10As shown, it includes a mounting frame 1, a sliding plate 2 is slidably connected in the mounting frame 1, a rubber plate 3 is installed on the sliding plate 2, a test tube 4 is placed between the sliding plate 2 and the rubber plate 3, a rotating plate 5 is rotatably installed on the mounting frame 1, the rotating plate 5 is an L-shaped structure, which can push the sliding plate 2, a gripping rod 6 is installed on the rotating plate 5, a sterilization lamp 7 is installed on the rotating plate 5, a locking assembly 8 is installed on the left and right sides of the upper part of the mounting frame 1, a first spring 9 is installed between the locking assembly 8 and the mounting frame 1, an inclined plate 10 is installed on the lower side of the mounting frame 1, a first connecting member 12 is installed on the lower side of the left and right parts of the sliding plate 2, a bearing plate 11 is slidably connected between the first connecting member 12, the bearing plate 11 can be pushed by the rotating plate 5, thereby moving upward along the inclined plate 10 to push the test tube 4, and the locking assembly 8 includes a mounting frame 82, the mounting frame 82 is installed on the left and right sides of the upper part of the mounting frame 1, and a bolt 81 is slidably connected to the mounting frame On 82, an annular power-assisting block is provided on the outer side of the bolt 81, and the guide block 83 is installed on the inner side of the bolt 81 and is clamped with the rotating plate 5. The first mounting plate 13 is installed on the front side of the mounting frame 1, and the second mounting plate 14 is installed on the rear side of the mounting frame 1. The guide rod 15 is installed between the first mounting plate 13 and the second mounting plate 14 and is slidably connected to the sliding plate 2. The second spring 16 is installed between the sliding plate 2 and the first mounting plate 13 and is sleeved on the corresponding guide rod 15. The mounting blocks 17 are arranged on the left and right sides of the lower part of the mounting frame 1, and the second connecting members 18 are installed on the corresponding mounting blocks 17. The second connecting members 18 are bent structures. The gripping blocks 19 are installed on the lower sides of the corresponding second connecting members 18 and contact the ground. The focusing plate 20 is rotatably connected to the rotating plate 5. The limit block 21 is installed on the rotating plate 5 for flipping and limiting the focusing plate 20. The rubber strip 22 is installed at the hinge of the rotating plate 5 and the mounting frame 1.

[0029] It should be noted that, in the initial closed state of the test tube 4 for storage and sterilization, the rotating plate 5 is in a vertical position and is firmly locked by the locking assembly 8. At this time, the long arm portion of the rotating plate 5 is fixed, and the sterilization lamp 7 installed thereon is facing the internal space of the test tube rack 4. At this time, the test tube 4 placed on the supporting plate 11 is simultaneously subject to constraints in two directions, the vertical thrust from the supporting plate 11 from bottom to top and the elastic clamping force applied from the side by the rubber plate 3 installed on the sliding plate 2. These two forces work together to tightly wrap the upper port of the test tube 4 with the elastic rubber plate 3, forming a physical seal to prevent the invasion of external contaminants. At the same time, the locking assembly 8 remains in a biting state at this time, and the latch 81 slides inward in the mounting frame 82. The guide block 83 on the inside thereof is under the action of the compressed first spring 9. The rotating plate 5 is firmly inserted into the locking groove of the rotating plate 5 to ensure that the rotating plate 5 will not loosen during the sterilization cycle. In this stable closed state, the sterilization lamp 7 is activated, and the ultraviolet light it emits (usually UVC band) irradiates the space inside the rack. The focusing plate 20 connected to the rotating plate 5 can be manually opened and the angle is adjusted by the limit block 21. The reflective surface is used to enhance the irradiation intensity and uniformity of ultraviolet light to key areas such as the mouth of the test tube 4, continuously killing potential pollutants. When it is necessary to take or place the test tube 4, the user needs to unlock it with one hand, pinch the annular assist block on the outside of the latch 81 of the locking assembly 8, overcome the tension of the first spring 9 and pull the latch 81 outward. This action drives the guide block 83 to disengage the locking groove of the rotating plate 5, releasing the mechanical constraint. Then the user holds the handle 6 installed on the rotating plate 5 , flip it from the vertical position toward the operator to the open state, the flipping movement of the rotating plate 5 triggers two sets of linkage mechanisms. First, the outer end of the long arm of the rotating plate 5 pushes the sliding plate 2 forward during the flipping process, and the sliding plate 2 drives the rubber plate 3 fixed thereon to move forward synchronously along the guide rod 15 passing through the second mounting plate 14. At the same time, the sliding plate 2 moves forward to compress the second spring 16 installed between the sliding plate 2 and the first mounting plate 13 to store energy. Secondly, when the rotating plate 5 flips, the inner side of the L-shaped structure corner will push the carrying plate 11. The carrying plate 11 is slidably connected to the mounting frame 1 through the first connecting members 12 on both sides. After receiving the thrust, it slides along the specific inclination angle track of the inclined plate 10. The inclined plate 10 guides the movement of the carrying plate 11, so that the The test tube 4 on the plate 11 is moved smoothly and synchronously. This combined action not only releases the vertical lifting force of the test tube 4, but also enables the test tube 4 to move as a whole to an ideal height for the operator to safely grasp, avoiding secondary contamination. At this point, the test tube 4 is completely freed from all fixed constraints and can be safely taken and placed. At the same time, the test tube 4 rack as a whole remains stationary under the anti-slip stability provided by the support structure at the bottom of the mounting frame 1. After the test tube 4 is replaced, the user flips the rotating plate 5 in the opposite direction to reset it. The second spring 16 compressed during the flipping process releases the energy stored, pushing the sliding plate 2 and the rubber plate 3 to automatically reset backward along the guide rod 15. At the same time, the rotating plate 5 is in the latter part of the swing-back motion. When the rotating plate 5 is fully reset, the guide block 83 of the locking assembly 8 is automatically reset under the action of the first spring 9.Driving the latch 81 to slide inward causes the guide block 83 to reengage the locking slot of the rotating plate 5, achieving a secure mechanical lock and completing the closing process. The sterilization lamp 7 is then automatically or manually activated, depending on the settings, to begin a new round of protective sterilization irradiation. The entire cycle is achieved by single-handedly operating the handle 6 to unlock, flip, and then flip and close, releasing and locking the test tube 4. The rubber strip 22 at the hinge absorbs shock, reduces vibration and noise during the opening and closing of the rotating plate 5, and increases rotational resistance to prevent shaking.
