Abstract
Description
Technical Field
[0001] This invention provides a fixation device for test strips, and particularly relates to a fixation device for test strips used to predict the efficacy of tumor treatment. Background Technology
[0002] The fixation device for tumor treatment efficacy test strips, which belongs to this apparatus, is an auxiliary tool used in tumor medical experiments to support and position efficacy test strips. Its core function is to stabilize and fix the test strips, and in conjunction with experimental operations, to detect the reaction of samples (such as blood and body fluids) of tumor patients before and after treatment. Then, the treatment effect can be judged by the color change or band difference of the test strips. Such devices are required to ensure the standardization of the detection process and the traceability of data in small-scale preliminary experiments, large-scale sample screening, and comparative experiments of different treatment regimens.
[0003] In existing technologies, such fixing devices are mostly simple flat bases with only scattered circular holes (without a uniform arrangement) or adhesive fixing structures (the test strip is directly adhered to the base surface). The former lacks coordinate positioning marks, which can easily confuse the sample correspondence when fixing multiple test strips at the same time, leading to misalignment of test data and samples. The latter is irreversible due to the adhesive method, making it impossible to flexibly replace failed test strips. In addition, test strip adhesive residue is easily left on the base surface, affecting reuse. Furthermore, the poor fit between the circular holes and the edge of the test strip, and the adhesive fixing method can easily cause test strip wrinkles, all of which interfere with the accuracy of the test results. They are difficult to meet the requirements of tumor efficacy prediction experiments for accurate test strip positioning, flexible fixing methods, and batch processing of multiple samples. Utility Model Content
[0004] In order to solve the above problems, this application provides a fixation device for test strips used to predict the efficacy of tumor treatment, which solves the problems of chaotic test strip positioning, insecure fixation, inconvenient replacement, and difficulty in reuse in existing devices.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fixing device for a test strip for predicting the efficacy of tumor treatment, comprising:
[0006] Fixture: It has a cuboid structure, and its upper surface has square mounting holes that are evenly distributed in a matrix array;
[0007] Coordinate markings: The horizontal edge of the fixing base is provided with sequentially arranged numerical markings, and the vertical edge is provided with sequentially arranged letter markings. The numerical markings and letter markings work together to locate the position of each square mounting hole in a coordinate form.
[0008] Fixing rods: Several rods, which are columnar structures. The lower end of each rod is a square column that is adapted to the shape of the square mounting hole and can be inserted into the square mounting hole. The upper end of each fixing rod is used to support and fix the test paper so that the test paper covers the area above the corresponding square mounting hole.
[0009] Preferably, the horizontal edge is the front edge of the fixing base, and the numerical identifiers are marked sequentially from left to right along the front edge; the vertical edge is the left edge of the fixing base, and the letter identifiers are marked sequentially from front to back along the left edge, and the intersection of the numerical identifier "1" and the letter identifier "a" corresponds to the square mounting hole in the first row and first column of the matrix.
[0010] Preferably, the upper end of the fixing rod is provided with a square support platform, the side length of the square support platform is greater than the side length of the square mounting hole, and the upper surface of the square support platform is a horizontal bearing surface for fitting and supporting the bottom surface of the test strip; the edge of the square support platform is adapted to the edge of the test strip to limit the lateral displacement of the test strip.
[0011] Preferably, the length of the square column of the fixing rod is 10-15mm, and the thickness of the fixing seat is 15-20mm, so that after the fixing rod is inserted into the square mounting hole, the distance between the square support platform and the upper surface of the fixing seat is 3-8mm, forming a vertical receiving space for the test paper.
[0012] Preferably, the square mounting hole has a chamfer at the entrance, and the lower end of the square column of the fixing rod has an inlet bevel that matches the chamfer, so that the square column can be quickly inserted into the square mounting hole, and the square column and the square mounting hole are in clearance fit, which facilitates disassembly and adjustment.
[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0014] This invention first uses a coordinate system composed of numerical markings on the horizontal edge and letter markings on the vertical edge of the fixing base to determine the position of the square mounting hole corresponding to the target test strip. The lower end of the fixing rod, with its inclined square column, is inserted into the corresponding hole using the chamfered guide at the entrance of the square mounting hole (the two can be flexibly disassembled due to their clearance fit). The upper end of the fixing rod, with a square support platform whose side length is greater than the mounting hole, is in contact with the bottom surface of the test strip with its horizontal bearing surface, and its edges restrict the lateral movement of the test strip. Furthermore, the length of the square column of the fixing rod (10-15mm) matches the thickness of the fixing base (15-20mm), creating a 3-8mm vertical space between the support platform and the upper surface of the fixing base to accommodate the test strip. Multiple fixing rods work together to achieve stable fixing of different test strips at the coordinate positions corresponding to the matrix holes, facilitating the recording and observation of test strip reactions related to the efficacy of tumor treatment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.
[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0025] like Figure 1 and Figure 2As shown, a fixing device for a test strip used to predict the efficacy of tumor treatment includes a cuboid fixing base 1 with square mounting holes 11 evenly distributed in a matrix array on its upper surface; the fixing base 1 has a number mark 21 on one side of its horizontal direction and a letter mark 22 on one side of its vertical direction, which are used to position each square mounting hole 11 in a coordinate manner; a number of columnar fixing rods 3 have square columns at their lower ends that are adapted to the square mounting holes 11 and can be inserted into the holes, and their upper ends are used to support and fix the test strip so that the test strip covers the area above the corresponding hole.
[0026] In this implementation scheme, the fixing base 1 serves as the overall supporting base, forming a rectangular structure to construct a stable supporting plane. The matrix array of square mounting holes 11 on its upper surface provides regular and evenly distributed mounting positions for the fixing rod 3, ensuring the regularity of the test strip layout. The numerical markings 21 on one side of the fixing base 1 and the letter markings 22 on one side of the vertical side form a two-dimensional coordinate system, so that each square mounting hole 11 corresponds to a unique coordinate (such as "a1" and "b3"). This solves the problem of difficulty in accurately marking the position of the test strip and easy confusion of experimental data in traditional fixing methods, and realizes the accurate correlation between the position of the test strip and the detection data in the detection of tumor treatment efficacy.
[0027] The lower end of the fixing rod 3 is provided with a square column that fits the square mounting hole 11. With the chamfer of the entrance of the square mounting hole 11 and the guide slope at the lower end of the column, the insertion guidance is improved to speed up the installation efficiency. At the same time, the clearance fit allows for convenient disassembly and position adjustment of the fixing rod 3, which meets the flexible fixing needs of different test strips. The square support platform at the upper end of the fixing rod 3, because its side length is larger than that of the square mounting hole 11, stabilizes the test strip with a horizontal bearing surface on the one hand, and forms a lateral limit by fitting the edge with the test strip on the other hand, so as to avoid the test strip shifting during the experiment and causing the detection area to be misaligned.
[0028] Meanwhile, the length (10-15mm) of the square column of the fixing rod 3 and the thickness (15-20mm) of the fixing seat 1 work together to form a vertical accommodation space of 3-8mm between the square support platform and the upper surface of the fixing seat 1. This avoids the test strip from directly sticking to the fixing seat 1 and interfering with the reaction, and also ensures the test strip is flat with the help of the vertical support of the fixing rod 3, which is conducive to clearly observing the changes in the test strip reaction related to the efficacy of tumor treatment.
[0029] In summary, through the structural synergy of "matrix mounting hole bearing + coordinate marking positioning + fixing rod adaptation fixing", this device achieves precise position marking, stable posture fixation, and convenient disassembly and adjustment of the test strip, which greatly improves the standardization and data reliability of tumor efficacy prediction experiments and solves the pain points of traditional fixation methods such as position confusion, unstable fixation, and obstructed observation.
[0030] like Figure 3 and Figure 4As shown, the number 21 is marked from left to right along the front edge of the fixing base 1, and the letter 22 is marked from front to back along the left edge. The intersection of "1" and "a" corresponds to the square mounting hole 11 in the first row and first column of the matrix. The upper end of the fixing rod 3 is provided with a square support platform with a side length greater than the hole. Its horizontal bearing surface is in contact with the bottom surface of the test strip, and the edge restricts the lateral displacement of the test strip. The square column of the fixing rod 3 is 10-15mm long, and the fixing base 1 is 15-20mm thick. After insertion, the distance between the support platform and the base surface is 3-8mm, forming a vertical space for the test strip. The entrance of the square mounting hole 11 is chamfered, and the lower end of the column of the fixing rod 3 is provided with an adaptive guide slope. The two are fitted together to achieve quick assembly and disassembly.
[0031] In this implementation plan, the use of this device can be categorized according to experimental scale, operational requirements, and recording methods, corresponding to different coordinate representation logics:
[0032] Based on experimental scale: In small-scale experiments, a small number of square mounting holes (such as coordinates "a1", "b2", "c3") are selected on the fixed base, and the corresponding test strips are fixed after the fixing rod is inserted. The position of a single test strip is directly marked by a single coordinate. In large-scale experiments, multiple sets of detection units are formed by a matrix distribution of mounting holes (such as horizontal "1-5" and vertical "ae" covering 25 holes). The position of the test strip group is recorded in batches by coordinate combination (such as "a1-a5" representing the first row of 5 test strips in the vertical direction, and "a1-e1" representing the first column of 5 test strips in the horizontal direction).
[0033] Based on operational requirements: For fixed testing, the fixing rod corresponding to the coordinates of the test strip (e.g., "d4") is inserted into place in one go, and the position remains unchanged throughout the experiment. The test data is directly associated with the initially recorded coordinates. For dynamic adjustment, if the test strip at a certain position needs to be replaced (e.g., the test strip at "c2" fails), the corresponding fixing rod is pulled out and replaced. The new test strip is still recorded at the original coordinate "c2" to ensure data continuity. For comparative experiments, the control group test strips are fixed in the same horizontal column of numbers (e.g., "column 1": "a1", "b1", "c1"), and the experimental group is fixed in the same vertical row of letters (e.g., "row b": "b1", "b2", "b3"). The analysis logic is simplified by cross-comparison of "column coordinates + row coordinates" (e.g., "b1" is the intersection point of the control and the experiment).
[0034] According to the recording method: When recording on paper, a matrix table corresponding to the fixed seat is drawn on the recording sheet, and the test strip information (such as sample number) is filled in the corresponding coordinate cell (such as "a1: sample X"); When recording electronically, a digital mapping relationship is established through coordinate coding (such as "a1→0101" "b2→0202"), and the test strip data is directly entered into the detection system, which is convenient for batch statistics and traceability.
[0035] In all usage scenarios, the core representation method is a combination of "horizontal numbers + vertical letters" coordinates to ensure a unique correspondence between the test strip position and the test data. Whether it is a single strip, a batch, or a dynamically adjusted strip, the target test strip can be quickly located using coordinates.
[0036] In one or more feasible embodiments, when using this device, it is necessary to use a pipette (for adding test samples such as blood or tissue fluid from cancer patients to test strips fixed on a square support platform), a marker pen (for marking the coordinate information of the corresponding fixing seat on the edge of the test strip, such as "a1" to match the fixing position), a timer (to control the reaction time between the test strip and the sample), an optical detector (for reading the color change or band information after the test strip reaction), and data recording software (to associate and store the results obtained by the optical detector with the coordinate markings); at the same time, the fixing seat can be injection molded from polypropylene (PP) material to ensure structural strength and chemical stability, and the fixing rod can be made of polyethylene. Made of PE material (with a certain degree of toughness and hardness to avoid scratching the test strip), the test strip itself is a special test strip for predicting the efficacy of tumor treatment in existing technology (such as colorimetric test strips based on antigen-antibody reactions). When using it, the test strip must first be picked up with tweezers (existing tools) and placed on the square support platform of the fixing rod. After the sample reaction is completed, the details of the test strip can be observed with the help of a magnifying glass (existing tools). If the device needs to be reused, the fixing base and fixing rod can also be cleaned with an ultrasonic cleaner (existing equipment) to ensure that subsequent experiments are not interfered with by residual samples. The combination of these existing technologies with this device realizes a complete experimental process from sample addition, reaction control, result observation to data recording.
[0037] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
