Description

TECHNICAL FIELD

[0001] The utility model relates to detection kit technical field especially, it relates to a breast cancer detection tool box. BACKGROUND

[0002] In the breast cancer screening and clinical detection process, the breast cancer detection tool box is the core tool for realizing sample standard storage, safe transportation and subsequent detection, and the rationality of the test tube clamping structure inside the breast cancer detection tool box directly affects the efficiency of detection operation and sample safety. Whether it is the single transportation of clinical sample test tubes by medical staff in medical institutions or the frequent taking and placing of multiple reagent tubes in community mobile screening scenarios, the stable fixation of test tubes needs to rely on the elastic clamping structure of the reagent box to avoid sample damage caused by test tube shaking or pouring, and the detection test tubes of different diameters need to be adapted to meet diversified detection needs.

[0003] The elastic clamping structure of the existing breast cancer detection tool box mainly realizes the adaptation and fixation of test tubes of different diameters by continuously applying clamping force to the contact block by the spring. Although this design can achieve basic clamping effect, it has obvious limitations in actual operation. Because the spring continuously applies clamping force to keep the contact block in close contact with the outer wall of the test tube, medical staff need to continuously overcome the friction between the two when inserting the test tube with sterile gloves. If the force is uneven, it may cause the test tube to tilt, and even cause the sample in the tube to spill. When taking out the test tube, the friction formed by the clamping force also hinders the operation. Medical staff need to use both hands to fix the reagent box with one hand and pull the test tube out by the top end with the other hand. Not only is the operation efficiency low, but also the test tube and the contact block may be scratched due to excessive force, affecting subsequent sample observation. In addition, in high-intensity use scenarios such as outdoor screening, frequent taking and placing operations will exacerbate the fatigue of medical staff's hands. If there is a small amount of reagent residue on the outer wall of the test tube, the friction will be further increased, increasing the risk of test tube damage and seriously affecting the smoothness of the detection process. Therefore, it is urgent to improve the existing technology to solve the problems of inconvenient operation, low efficiency and easy damage of the test tube caused by the elastic clamping structure in the breast cancer detection tool box.

[0025] Please refer to Figures 1 to 5 , the present embodiment provides a breast cancer detection tool box, mainly including a kit body 1, a test tube 2 and a core elastic clamping assembly 5.

[0026] The kit body 1 is the main structure, which is usually made of hard plastic or other suitable materials, and one or more test tube holes 3 are formed on it for accommodating the test tube 2. The bottom of the test tube hole 3 is provided with an elastic reset piece 4, which is preferably a spiral spring. The top end of the elastic reset piece 4 is provided with a supporting piece in contact with the bottom of the test tube 2, which provides an auxiliary upward restoring force after pressing the test tube 2, so that the test tube 2 can be partially ejected and easily taken.

[0027] Please refer to Figure 1 , Figure 2 and Figure 3, the elastic clamping assembly 5 is the core of the utility model, it includes clamping structure 51 and locking structure 52. The reagent box body 1 is evenly provided with a plurality of horizontally arranged first mounting holes 6 along the circumference of test tube hole 3, and the clamping structure 51 is accommodated in the first mounting hole 6. The reagent box body 1 is also provided with a plurality of vertically arranged second mounting holes 7, and the second mounting hole 7 is communicated with the first mounting hole 6 where each clamping structure 51 is located, and the locking structure 52 is accommodated in the second mounting hole 7.

[0028] The clamping structure 51 includes a contact block 511, a connecting shaft 512, a first locking piece 513, a movable piece 514 and a first spring 515. One end of the connecting shaft 512 is fixedly connected with the contact block 511, and the other end is fixedly connected with the first locking piece 513, so that the contact block 511, the connecting shaft 512 and the first locking piece 513 form a synchronous moving whole. The movable piece 514 is slidably sleeved on the connecting shaft 512 along the axial direction of the connecting shaft 512. One end of the first spring 515 abuts against the end of the first mounting hole 6, and the other end abuts against the first locking piece 513, to provide the first locking piece 513 with elastic force towards the axis of the test tube hole 3, and the elastic force is transmitted through the connecting shaft 512, so that the contact block 511 always has a tendency to move towards the axis of the test tube hole 3.

[0029] The locking structure 52 includes a second locking piece 521 and a second spring 522. One end of the second spring 522 abuts against the bottom of the second mounting hole 7, and the other end abuts against the second locking piece 521, to provide the second locking piece 521 with downward vertical reset elastic force. The second locking piece 521 forms a slope cooperation with the slope 513a of the first locking piece 513 and the slope 514a of the movable piece 514 through the slope 521a arranged on the second locking piece 521.

[0030] In the embodiment, the first locking piece 513 and the movable piece 514 are both in trapezoidal structure. The large end surface 513b of the first locking piece 513 faces the axis direction of the test tube hole 3, and the large end surface 514b of the movable piece 514 faces away from the axis direction of the test tube hole 3. This specific structure of the direction of cooperation with the slope is the key to realize state switching.

[0031] The outer wall of the test tube 2 is provided with a protruding ring 21, the height of the protruding ring 21 is matched with the position of the contact block 511, and the position of the protruding ring 21 is accurately designed, when the test tube 2 is pressed down, it can just push the contact block 511 to move away from the axis of the test tube hole 3. When the contact block 511 is in the pressing position, the end surface near the axis of the test tube hole 3 is in arc shape matched with the outer wall of the test tube 2, to provide uniform clamping force.

[0032] Please refer to Figures 4 to 6The working principle of the utility model is as follows: initial placement state (unlocked state): at this time, the contact block 511 is in the compression position under the elastic force of the first spring 515, closely adheres to the outer wall of the test tube 2, and provides stable clamping force. The inclined surface 513a of the first locking piece 513 is attached to the inclined surface 521a of the second locking piece 521.

[0033] Locking process (from unlocking to locking): when the test tube 2 needs to be taken out, the test tube 2 is lightly pressed, the test tube 2 is moved downward, and the convex ring 21 on the test tube 2 pushes the contact block 511 to move away from the axis of the test tube hole 3. The contact block 511 drives the first locking piece 513 and the movable piece 514 to move synchronously through the connecting shaft 512. The inclined surface 513a of the first locking piece 513 acts on the inclined surface 521a of the second locking piece 521, drives the second locking piece 521 to compress the second spring 522 and move upward. When the second locking piece 521 passes the highest point of the inclined surface 513a of the first locking piece 513, it falls under the drive of the second spring 522, and the lower end is abutted on the large end surface 513b of the first locking piece 513, realizing mechanical locking (as shown in Figure 4 At this time, the contact block 511 is locked in the retracted position and is separated from the test tube 2, and the clamping force disappears, so that the test tube 2 can be easily taken out.

[0034] Unlocking process (from locking to unlocking): when the test tube 2 needs to be placed and fixed, since the contact block is in the locked state (retracted), the test tube 2 can be easily inserted into the bottom of the test tube hole 3. Then, the test tube 2 is continuously pressed downward, the convex ring 21 again pushes the contact block 511 to move away from the axis of the test tube hole 3, and the first locking piece 513 and the movable piece 514 are synchronously moved through the connecting shaft 512. At this time, the inclined surface 514a of the movable piece 514 acts on the second locking piece 521, drives the second locking piece 521 to compress the second spring 522 and move upward, until the large end surface 514b of the movable piece 514 moves to be attached to the large end surface 513b of the first locking piece 513. At this time, the second locking piece 521 is separated from the large end surface 513b of the first locking piece 513, and the locking is released. The contact block 511 is quickly moved inward to the compression position under the elastic force of the first spring 515, firmly fixes the test tube 2, and returns to the unlocked (clamping) state as shown in Figure 4 .

[0035] In summary, the embodiment converts the linear pressing action of the test tube into the state switching signal of the clamping assembly through the ingenious mechanical structure design, realizes the intelligent control of the test tube clamping and releasing, fundamentally solves the core problem of the inconvenient operation of the traditional elastic clamping structure, and significantly improves the use efficiency and safety of the breast cancer detection tool box.

[0036] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
