Description

Technical Field

[0001] This utility model relates to the technical field of drug sensitivity testing, and in particular to a disc-type drug sensitivity test disc. Background Technology

[0002] In the fields of microbial testing and clinical diagnosis, drug susceptibility testing is a crucial step in guiding rational drug use. Its core lies in providing a scientific basis for developing clinical medication regimens by detecting the sensitivity of microorganisms to different drugs. Among these, the single-drug mode is one of the commonly used testing methods. This mode sets different parameters, such as different concentrations and ratios, for the same drug to analyze the dose-response relationship between drug concentration and microbial sensitivity, providing data support for accurately determining drug dosage.

[0003] Currently, most mainstream drug susceptibility testing devices on the market adopt a plate-like structure. This type of structure arranges multiple drug chambers in an array inside the plate, which can be used for parallel detection of multiple drugs as well as adapt to the multi-parameter detection needs in single-drug mode. However, existing plate-like drug susceptibility testing structures have many problems that need to be solved in practical applications: First, classification and differentiation are difficult; in single-drug mode, it is necessary to distinguish different concentrations and ratios of the same drug. However, the drug chambers in the plate-like structure are densely arranged in an array and are numerous, lacking an intuitive identification system suitable for single-drug multi-parameter scenarios. Operators find it difficult to quickly identify specific concentration, ratio, and other parameter groups when adding drugs and interpreting results. This not only reduces operational efficiency but also easily leads to interpretation errors due to parameter confusion, affecting the accuracy of dose-effect relationship analysis. Secondly, it suffers from poor automation adaptability. Single-drug mode requires accurate matching of different drug solutions to dedicated drug compartments. However, due to the limitations of the plate-like structure and the compact arrangement of the drug compartments, this type of device is difficult to adapt to the operational requirements of automated sample dispensing equipment. During automated sample dispensing, problems such as misalignment and dispensing deviations easily occur, leading to a high automation failure rate. Furthermore, the complex array structure increases the difficulty of customized processing for single-drug, multi-parameter scenarios during production. Thirdly, waste collection is inconvenient. The edges and corners of the plate-like structure are mostly right angles or acute angles. During waste collection after testing, collisions and compression can easily cause leakage of residual solution from the drug compartment, resulting in environmental pollution and safety hazards. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by providing a disc-shaped drug sensitivity test disc, which solves the problems of difficult classification and differentiation, poor automation adaptability and inconvenient waste collection in the existing plate-shaped drug sensitivity test structure.

[0005] The technical solution of this utility model includes a disc-shaped disc body, which includes a central marking area located at the center and a placement area disposed on the outer ring of the central marking area. The placement area is provided with multiple drug chambers for containing drug sensitivity detection solutions, and the drug chambers are evenly distributed around the outer periphery of the central marking area.

[0006] By adopting the above technical solution, the overall shape and layout of the drug sensitivity tray are changed by using a disc-shaped structure and a radial layout from the center to the periphery, replacing the traditional plate-shaped array layout. This layout naturally has excellent distinguishability and guidance. The layout of drug compartments evenly distributed around the periphery of the central marking area is more regular and the spacing is clearer, making it easier for operators to intuitively distinguish different drug compartments to reduce visual confusion. Drug compartments can be easily located and identified around the central marking area, improving the interpretation obstacles caused by the large number and difficulty in classifying and distinguishing them in the traditional array structure. At the same time, the disc shape without sharp edges and corners provides convenience for subsequent stacking and storage, leakage prevention and easy operation during waste collection, and is more easily adapted to the operating trajectory of circular automated equipment compared to the plate structure.

[0007] In one possible design, the central marking area is provided with point markings for locating at least some of the medicine bins. The point markings include a starting point marking to identify the initial medicine bin, and / or interval markings to identify medicine bins at predetermined intervals.

[0008] With the above design, the point markers provide absolute and relative visual coordinate reference systems, the starting point markers provide an absolute zero reference point, and the interval markers divide the continuous drug bins into logical groups. This enables the system to quickly, accurately, and unambiguously locate the target drug bin, whether during manual operation or automated equipment recognition. It reduces operational errors and automation failures caused by incorrect point counts or positioning deviations, improves interpretation efficiency, reduces the risk of human misjudgment, and effectively solves the problems of difficult classification and certain obstacles to interpretation. It is especially suitable for rapid group recognition in scenarios such as single drug with multiple concentrations.

[0009] In one possible design, the upper and lower surfaces of the disc are provided with a stacking positioning structure for the vertical connection of the drug sensitivity discs.

[0010] By adopting the above design, the stacked positioning structure effectively solves the problems of messy stacking and easy tipping of traditional plate-shaped structures, allowing multiple drug sensitivity trays to be stably stacked in the vertical direction, thus saving storage and transportation space significantly. This orderly stacked structure can also match the gripping and stacking actions of automated feeding and unloading equipment. Automated equipment (such as robotic arms and sample loading machines) can easily grip, move or process multiple drug sensitivity trays stacked together at once, avoiding equipment jamming caused by disordered stacking, thereby reducing the failure rate of automated operations and providing the preconditions for automated operation.

[0011] In one possible design, the stacked positioning structure includes at least two limiting protrusions protruding from the surface of the disc and an annular ridge protruding from the bottom of the disc; the annular ridge can be fitted over the outer side of each limiting protrusion of another drug sensitivity disc body to form a limiting fit that restricts horizontal movement.

[0012] The above design, when stacked, forms a sleeve-type limiting mechanism by attaching the ring edge to the outside of the limiting protrusions on the lower disc, which effectively restricts the sliding and displacement of the disc in the horizontal direction, solving the problem of easy misalignment in traditional stacking. At the same time, the cooperation of at least two limiting protrusions with the ring edge can form multi-point positioning, avoiding rotation or tilting of the disc during stacking, which is especially suitable for long-distance transportation after batch stacking to ensure stacking stability. In addition, this cooperation between the protrusion and the ring edge does not require complex buckles or connectors, and positioning can be completed simply by placing and fitting, which is convenient to operate and has a simple structure that is easy to process, effectively reducing production costs.

[0013] In one possible design, at least one locating bump also serves as a position marker, and the locating bump that serves as a position marker differs from other locating bumps in size, shape, and / or color.

[0014] The above design integrates the functions of stacking positioning and drug compartment marking into the same component, realizing the reuse of structure and function. This reduces structural redundancy on the disc surface and lowers the difficulty of mold design and processing, thereby saving manufacturing costs. At the same time, by distinguishing functional protrusions by differentiating features, confusion with ordinary limit protrusions can be avoided, ensuring that both functions can be stably implemented, thus taking into account both practicality and reliability.

[0015] In one possible design, the central identification area includes text-based and / or QR code-based identification information.

[0016] The above design provides a multi-level, multi-media information identification method. Text-based information interpretation allows for direct and rapid reading of basic information on the disc (such as drug name, batch number, etc.) by humans. Information interpretation by scanning (such as QR codes and barcodes) facilitates the rapid and accurate collection of large amounts of information by automated equipment and enables integration with information systems to achieve sample tracking, automated data entry and management, reduce human error in recording, and improve the informatization and reliability of the testing process.

[0017] In one possible design, the outer wall of the placement area is provided with a side labeling area for identifying the overall information of a single drug sensitivity disc.

[0018] The above design incorporates side markings, providing rapid identification capabilities in a stacked state. When multiple drug sensitivity test trays are stacked, the central marking area on the top surface will be covered, while the side marking areas remain visible. This allows operators or equipment to quickly identify the entire stack of drug sensitivity test trays without separating them, greatly facilitating inventory and retrieval operations during warehousing, logistics, and experimental preparation, improving work efficiency, and avoiding confusion.

Central marking area; 11. Point markings; 2. Placement area; 21. Medicine compartment; 31. Limiting protrusions; 32. Ring edge; 4. Side marking area. Detailed Implementation

[0020] like Figures 1 to 4 The illustrated disc-type drug sensitivity test tray includes a disc-shaped body made of a chemically resistant and biocompatible material, preferably a transparent or translucent plastic material, injection molded in one piece for easy observation of the internal components. The central area of ​​the tray is a central identification area 1, which does not contain drug reservoirs 21 and serves only as a functional identification area. A placement area 2 surrounds the central identification area 1, and the placement area 2 and the central identification area 1 are integrally molded, forming a clear division on the tray surface. Multiple drug reservoirs 21 are located within the placement area 2, all evenly spaced along the outer periphery of the central identification area 1, with consistent spacing between adjacent reservoirs. The openings of the drug reservoirs 21 face upwards, and their interiors form cavities or holes for containing drug sensitivity test solutions, their shapes adapted to the requirements of conventional drug sensitivity test solutions. This radial, circumferentially distributed layout, compared to a traditional rectangular array layout, offers greater visual guidance and differentiation, making it easier for operators to locate and identify specific drug reservoirs 21.

[0021] A point mark 11 is set on the surface of the central identification area 1. This point mark 11 is used to locate and mark some of the drug containers 21 in the placement area 2. The point mark 11 includes a starting point mark and an interval mark: the starting point mark is set in the central identification area 1 near a specific drug container 21. Its shape is clearly different from other marks so that operators can quickly identify it and use the corresponding drug container 21 as the starting point for sorting; the interval mark is set according to a predetermined interval rule, that is, every time a predetermined number of drug containers 21 are separated, an interval mark is set at the corresponding position in the central identification area 1. By combining the starting point mark and the interval mark, the continuously distributed drug containers 21 can be divided into multiple groups, which makes it easier to distinguish the detection solutions with different parameters.

[0022] like Figures 2 to 4 As shown, to achieve vertical stacking of multiple drug sensitivity discs, a stacking positioning structure is provided on the upper surface (disc face) and lower surface (disc bottom) of the disc body. This structure is integrally formed with the disc body and requires no additional assembly. The overall design of the stacking positioning structure must ensure that the upper and lower drug sensitivity discs can be accurately aligned when stacked, and that there will be no relative offset after stacking. At the same time, it should not affect the normal use of the drug compartment 21, that is, the height of the stacking positioning structure will not obstruct the opening of the drug compartment 21, nor will it interfere with other functional areas.

[0023] The stacked positioning structure consists of limiting protrusions 31 and annular ridges 32. The limiting protrusions 31 protrude from the upper surface of the disc body, with at least two, preferably four, and are symmetrically distributed along the outer periphery of the upper surface of the disc body to ensure positioning stability. The annular ridges 32 protrude from the lower surface of the disc body, and their shape matches the outer periphery of the disc body. The inner diameter of the annular ridges 32 matches the diameter of the circumscribed circle formed by the multiple limiting protrusions 31. When two drug sensitivity discs are stacked, the annular ridges 32 at the bottom of the upper drug sensitivity disc can fit snugly over the outer sides of each limiting protrusion 31 of the lower drug sensitivity disc. Through the close fit between the annular ridges 32 and the limiting protrusions 31, the sliding and rotation of the upper and lower drug sensitivity discs in the horizontal direction are restricted, achieving a stable stacked state.

[0024] like Figure 2 , Figure 3 As shown, at least one positioning protrusion 31 is used simultaneously as a position mark 11. To achieve this function, the positioning protrusion 31 that also serves as a position mark 11 is visually distinct from other positioning protrusions 31 that simply serve a positioning function. The differences can be one or more of the following: in terms of size, the positioning protrusion 31 that also serves as a mark is larger or smaller than other protrusions; in terms of shape, the positioning protrusion 31 that also serves as a mark adopts a shape other than an arc, such as a square or triangle; in terms of color, different coloring treatments are used to distinguish the positioning protrusion 31 that also serves as a mark from other protrusions. Operators can use this distinguishing protrusion to simultaneously confirm positioning during stacking and identify the starting point / group of the medicine compartment 21.

[0025] In the central identification area 1, excluding point marker 11, interpretation information is provided. This interpretation information includes one or both of the following: text interpretation information and barcode interpretation information. The text interpretation information uses clearly legible printed fonts and may include basic information such as drug name, test items, and production date. The barcode interpretation information can be set as a QR code or barcode, which stores information including not only basic information but also detailed data such as testing standards and reference ranges. Operators can quickly understand the basic content by manually reading the text information or obtain complete data by scanning the barcode information, enabling rapid data entry and traceability.

[0026] On the outer wall of the placement area 2, i.e., the circumferential side of the disc, there is a side marking area 4. The side marking area 4 is marked with information by printing or laser engraving, which includes general information about a single drug sensitivity disc, such as batch number, detection object, and applicable instrument model. Because it is located on the circumferential side, when multiple drug sensitivity discs are stacked, the marking information can be seen from the side without disassembling the stack, which facilitates quick screening and management of drug sensitivity discs of different batches or types. In use, operators or automated equipment first quickly locate the corresponding drug sensitivity testing solution or sample by using the position marks 11 and identification information in the central identification area 1, and then add the appropriate solution or sample to each drug compartment 21. Due to the disc-shaped layout and clear markings, this process is accurate and efficient.

[0027] After the test is completed, when culture or storage is required, multiple drug sensitivity trays can be stably stacked by the cooperation of the bottom ring ridge 32 and the limiting protrusion 31 on the tray surface, which saves space and is easy to transport, and is especially suitable for automated production line operation.

[0028] When disposed of as waste, the drug sensitivity disc, with its rounded outer perimeter and smooth transitions, without sharp edges, can be easily placed into a plastic bag for collection. The smooth shape avoids the risk of puncturing the plastic bag, and the stable structure after stacking prevents leakage of residual solution from the drug compartment 21 due to collisions or compression inside the bag, effectively preventing secondary pollution and solving the problem of inconvenient waste collection.
