Description

Technical Field

[0001] This utility model belongs to the field of medical testing technology, specifically relating to a molecular detection kit for medical testing. Background Technology

[0002] Existing molecular diagnostic kits for medical testing suffer from significant contamination risks and low efficiency during practical use, primarily due to their open reagent addition methods and sample management designs. In routine testing procedures, operators need to open the kit multiple times to complete critical steps such as reagent addition and sample transfer. This repetitive operation not only increases workload but also frequently exposes the internal environment of the kit to the outside air, significantly increasing the risk of aerosol contamination and cross-contamination. Especially when processing multiple samples, traditional kits typically employ a shared reaction space design, lacking effective physical isolation measures. When one sample is contaminated, the contamination can easily spread to other sample areas, severely impacting the reliability of the entire batch of test results. Therefore, this invention proposes a novel molecular diagnostic kit for medical testing to address these problems. Utility Model Content

[0003] The purpose of this invention is to provide a molecular diagnostic kit for medical testing that can solve the above-mentioned technical problems.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] This utility model provides a molecular detection box for medical testing, including a box body, a pull-out frame assembly and a linkage rotation assembly. The pull-out frame assembly is disposed inside the box body, and the linkage rotation assembly is disposed on the box body and corresponds to the pull-out frame assembly inside the box body.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figure 1-6 As shown, a molecular detection kit for medical testing includes a box body 1, a pull-out frame assembly 2, and a linkage rotation assembly 3. The pull-out frame assembly 2 is disposed inside the box body 1, and the linkage rotation assembly 3 is disposed on the box body 1 and corresponds to the pull-out frame assembly 2 inside the box body 1.

[0028] The top plate of the housing 1 is provided with a through hole 11 that cooperates with the linkage rotation component 3, and the two sides inside the housing 1 are fixed with sliding groove plates 12 that cooperate with the pull-out frame component 2.

[0029] The pull-out frame assembly 2 includes a support plate 21 and a dividing plate 22. The support plate 21 is set inside the housing 1 and its two sides are respectively slidably engaged with two sliding groove plates 12. The dividing plate 22 is set inside the housing 1 and fixed on the support plate 21. The dividing plate 22 is set in a cross shape.

[0030] The linkage rotating assembly 3 includes a movable cover 31 and a notched disc 32. The movable cover 31 is movably disposed on the surface of the housing 1. The notched disc 32 is shaped like a three-quarter disc and is movably fitted in the recess 13a. The recess 13a is opened on the baffle plate 13. The baffle plate 13 is fixed to the upper side inside the housing 1. An adjusting shaft 33 is provided on the upper side of the baffle plate 13 inside the housing 1. The adjusting shaft 33 is disposed in the through hole 11 and its lower side is mounted on the notched disc 32. The adjusting shaft 33 is slidably fitted on the stabilizing plate 34, and the stabilizing plate 34 is fixed to the inner wall of the through hole 11. The upper side of the adjusting shaft 33 slides through the movable cover 31. The surface of the movable cover 31 is provided with a rotation adjustment mechanism for lifting and rotating the notched disc 32.

[0031] As an optional implementation, two parallel misaligned locking plates 32a are fixed on the bottom surface of the notched plate 32. The two misaligned locking plates 32a are misaligned with the sides of the longitudinal or transverse plates on the dividing plate 22. This allows the notched plate 32 to be rotated and adjusted so that the two misaligned locking plates 32a can be misaligned and locked into the sides of the dividing plate 22 corresponding to the notch, thereby improving the sealing effect on the area of ​​the dividing plate 22 corresponding to the notch and reducing the impact on other areas of the dividing plate 22.

[0032] See attached document Figure 2 and attached Figure 5 The rotating adjustment mechanism includes a fixed plate 38, a lifting plate 310, and a linkage plate 311. The lifting plate 310 is positioned above the movable seat 39 and below the fixed plate 38. The fixed plate 38 is fixed to the surface of the movable cover 31. The movable seat 39 is positioned above the movable cover 31. One side of the lifting plate 310 is rotatably connected to the fixed plate 38 through the movable seat 39. The lifting plate 310 is made of a tough material and has the ability to bend and deform when pulled upwards. This allows the lifting plate 310 to withstand the displacement generated when the linkage plate 311 moves the adjustment rod upwards when it is subjected to force close to the fixed plate 38, thus not affecting the up-and-down sliding operation of the adjustment rod.

[0033] Furthermore, two screws are provided on the upper part of the movable cover 31. One screw passes through the upper side of the linkage plate 311 and is threaded to the other side of the grip plate 310. The other screw passes through the lower side of the linkage plate 311 and is threaded to the lifting block 36. The lifting block 36 is welded and fixed to the surface of the adjusting shaft 33. In this way, the grip plate 310 can rely on the linkage plate 311 to realize the upward lifting operation of the adjusting rod.

[0034] Furthermore, the movable cover 31 is attached around the through hole 11 on the top plate of the housing 1. A clamping nut 35 is pressed onto the surface of the movable cover 31, and the clamping nut 35 is threaded with the upper side of the adjusting shaft 33. The movable cover 31 is made of rubber, so that the movable cover 31 and the surface of the housing 1 are in a state of compression, which facilitates the rotation adjustment mechanism to achieve rotation adjustment.

[0035] Furthermore, the movable cover 31 has an addition hole corresponding to the notch on the notch plate 32, and an inner cover 37 is fitted inside the addition hole. In this way, by removing the inner cover 37, the detection object in the four areas can be added in a single blocking and sealing manner by rotating and adjusting the notch plate 32, thereby reducing the impact on other areas.

[0036] Furthermore, the side of the box 1 is set to be open, and the side of the box 1 is provided with a back plate 23 connected to the support plate 21. The back plate 23 has a shrinkable surface that fits into the opening of the box 1. This allows the back plate 23 to be embedded into the opening of the box 1, improving the sealing effect after the pull-out frame assembly 2 and the box 1 are combined.

[0037] Furthermore, the top surfaces of the dividing plate 22 and the shielding plate 13 are fitted with a gap, so that when the pull-out frame assembly 2 moves the dividing plate 22 inside the box 1, the shielding plate 13 blocks the dividing plate 22, thereby cooperating with the linkage rotation assembly 3 to add reagents to the test material in the four areas formed by the dividing plate 22.

[0038] Using the above structure, the following steps are included:

[0039] 1. In the initial state, the complete portion of the notched disk 32 completely covers the three areas of the dividing plate 22, forming a sealed state;

[0040] 2. When it is necessary to add sample reagents from other areas, the operator first pulls the lifting plate 310 upwards, and the adjusting shaft 33 is driven to rise through the linkage plate 311, so that the notch plate 32 is separated from the shielding plate 13, and at the same time the misaligned clamping plate 32a is also misaligned with the surface of the dividing plate 22.

[0041] 3. Rotate the lifting plate 310 to 90° to drive the notched plate 32 to rotate synchronously. At this time, the notched part of the notched plate 32 is aligned with the target addition area, while the other three areas remain closed.

[0042] 4. Remove the inner cap 37 from the filling hole and add the reagent to the designated area through the exposed notch, keeping the other three areas completely isolated during the addition process;

[0043] 5. After adding, reset the inner cover 37 and rotate the lifting plate 310 in the opposite direction to restore the notched plate 32 to its initial position. At this time, the misaligned locking plate 32a will accurately lock into the corresponding position of the dividing plate 22 to ensure sealing.

[0044] 6. If reagents need to be added to other areas, repeat steps 2-5 above, exposing only one area to be operated on at a time.

[0045] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
