Description

Technical Field

[0001] This invention relates to the field of microbial detection technology, specifically to a portable rapid detection device for microbial drug resistance. Background Technology

[0002] Antimicrobial resistance testing refers to the technical methods used to determine the tolerance of bacteria, fungi, and other microorganisms to various antimicrobial drugs, clarifying their resistance spectrum. Its core purpose is to guide clinical medication use and monitor the prevalence of drug-resistant bacteria. Its applications cover clinical treatment, disease control monitoring, animal husbandry, and food hygiene, helping to avoid the overuse of antimicrobial drugs and reduce the risk of treatment failure.

[0003] Antimicrobial resistance testing is crucial because drug-resistant bacteria can spread through multiple routes, leading to uncontrollable infections, prolonged disease courses, and even death, while also exacerbating the healthcare burden.

[0004] Currently, the mainstream detection methods include: traditional paper disc diffusion method (simple operation and low cost), dilution method (accurate determination of minimum inhibitory concentration), as well as molecular biology methods (such as PCR technology), mass spectrometry and other rapid detection technologies, which can realize rapid screening of drug resistance genes or drug resistance phenotypes and meet the detection needs of different scenarios. In the field of antimicrobial resistance testing, traditional testing equipment suffers from being bulky and inconvenient to assemble and disassemble, making it difficult to adapt to mobile testing scenarios such as clinical sites and primary healthcare institutions. Furthermore, its lack of portability leads to difficulties in transportation and storage. At the same time, existing testing methods mostly rely on manually adding test strips or antimicrobial reagents, which is cumbersome and inefficient, and cannot achieve batch testing. Therefore, it is necessary to propose a portable rapid antimicrobial resistance testing device. Summary of the Invention

[0005] To address the problems in existing technologies, this invention provides a portable rapid detection device for microbial drug resistance.

[0006] The technical solution adopted by this invention to solve its technical problem is: a portable rapid detection device for microbial drug resistance, comprising a base and a dish with a notch. A servo motor is installed inside the base, and a turntable is fixedly connected to the output end of the servo motor. A detection component is provided at the top of the base. The detection component includes a detection housing on the base. The detection housing has a storage tank, a conveying channel at the lower end of the storage tank, a discharge channel communicating with the conveying channel, and a top channel communicating with the discharge channel. A stud is fixedly connected to the bottom of the detection housing. A second servo motor is installed on the outer wall of the detection housing. A belt roller is fixedly connected to the output shaft of the second servo motor. A conveyor belt is connected between the belt rollers. A support plate is fixedly connected to the lower end of the top groove, and a liquid storage cylinder is installed at the upper end of the top groove. A pump body is fixedly connected to the top center of the support plate. A liquid guide head is fixedly connected to the output end of the pump body. Multiple connecting pipes connected to the inner end of the liquid storage cylinder are fixedly connected to the input end of the pump body. A partition plate is fixedly connected to the inner end of the liquid storage cylinder.

[0007] Specifically, a locking element is slidably engaged within the notch of the vessel plate, and multiple toothed blocks are fixedly connected to the inner arc side of the locking element. An annular groove is formed on the outer wall of the base, and multiple toothed blocks are fixedly connected to the annular groove near the locking element. Multiple vessel slots are formed at the top of the vessel plate, and a locking block is fixedly connected to the outer wall of the locking element. Sliding strips are fixedly connected to the outer walls on both sides of the locking block, and bolts are threaded onto both outer walls of the locking block.

[0008] Specifically, each of the vessel plates has a groove with a diameter matching that of the slide bar, and a snap-fit ​​opening has a mounting hole with a diameter matching that of the bolt at the inner end of the snap-fit ​​opening.

[0009] Specifically, several of the tooth blocks two mesh with tooth block one.

[0010] Specifically, the dish is snapped into the annular groove, and friction washers are provided on the transverse contact surfaces of the dish and the annular groove.

[0011] Specifically, the top of the turntable has a screw hole, and the screw hole is threadedly connected to the stud.

[0012] Specifically, the top of the liquid storage cylinder is equipped with multiple liquid inlet pipes, and the liquid inlet pipes and multiple connecting pipes correspond to the chambers between the partition plates.

[0013] Specifically, there is a gap between the conveying trough and the conveyor belt, and a sealing cap is snapped into the upper end of the storage trough.

[0014] The first beneficial effect of this invention is its excellent portability and ease of assembly / disassembly, adapting to various testing scenarios. The container tray features a detachable design, achieving quick fixation and disassembly through a toothed block engagement and bolt locking structure. Combined with friction washers, this ensures testing stability while reducing wear during assembly and disassembly. The testing components are connected via threaded studs and screw holes, allowing for individual assembly, disassembly, and storage, reducing space requirements during transport. The overall structure is lightweight and compact, requiring no complex tools for assembly and maintenance, making it easy to carry to clinical sites, primary healthcare institutions, or outdoor testing scenarios. This effectively solves the problems of traditional testing equipment being bulky and inconvenient to move, significantly improving testing flexibility and practicality.

[0015] The second beneficial effect of this invention is that it achieves rapid and accurate detection of microbial resistance, balancing efficiency and detection diversity. The storage tank in the detection component can stack test strips, and a conveyor belt enables precise single-sheet delivery and batch dispensing. Combined with the precise positioning of a servo motor, the docking of test strips and samples can be completed without manual operation, shortening the detection cycle. The liquid storage cylinder is divided into multiple independent chambers by partitions, which can store antimicrobial reagents of different concentrations. A quantitative pump and liquid guide head enable precise reagent dispensing, supporting multi-concentration comparison detection. Two detection modes adapt to different detection needs.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-8 As shown, the present invention provides the following technical solution: Example 1: A portable rapid detection device for microbial drug resistance includes a base 1 and a notched dish 2. A locking element 21 is slidably engaged within the notch of the dish 2. Multiple toothed blocks 211 are fixedly connected to the inner arc side of the locking element 21. An annular groove 101 is formed on the outer wall of the base 1. Multiple toothed blocks 211 are fixedly connected to the annular groove 101 near the locking element 21. Multiple dish slots 201 are formed at the top of the dish 2. A locking block 22 is fixedly connected to the outer wall of the locking element 21. A sliding strip 210 is fixedly connected to the outer side wall. Bolts 23 are threaded onto both outer walls of the locking block 22. A sliding groove 202 with a diameter matching the diameter of the sliding strip 210 is opened in the notch of the vessel plate 2. A locking slot 203 is opened on the vessel plate 2. An installation hole with a diameter matching the bolt 23 is opened at the inner end of the locking slot 203. Several toothed blocks 211 mesh with toothed blocks 211. The vessel plate 2 is locked into the annular groove 101. Friction washers are provided on the transverse contact surfaces of the vessel plate 2 and the annular groove 101.

[0021] The dish tray 2 features a detachable design, which is connected to the base 1 via a ring groove 101 and locked in place by a locking component 21 for quick fixation and disassembly. The first tooth block 211 and the second tooth block 11 mesh tightly, the slide bar 210 slides smoothly with the slide groove 202, and the bolt 23 is equipped with an anti-slip pad to enhance the locking effect. The friction washer is made of elastic and wear-resistant material, which not only enhances the stability of the dish tray 2 but also prevents wear on the contact surface during disassembly and assembly. The overall structure is lightweight and compact, greatly improving the portability of the device.

[0022] In use, align the dish 2 with the annular groove 101 of the base 1 and insert it. Push the locking piece 21 to make the slide bar 210 slide along the slide groove 202 until the first tooth block 211 and the second tooth block 11 are fully engaged, and it is initially fixed. Tighten the bolts 23 on both sides of the locking block 22. The dish 2 is double-reinforced by the anti-slip pad and the friction washer to prevent the dish 2 from shifting during the test. Then, place the test dishes containing microbial samples one by one into the dish groove 201 of the dish 2, and close the dish lid to wait for the test. After the test is completed, loosen the bolts 23 to quickly remove the dish 2. It is easy to disassemble and assemble, and convenient to carry, transport and clean.

[0023] Example 2: The technical solution of this example that differs from that of Example 1 includes: a servo motor 12 is installed inside the base 1, and a turntable 13 is fixedly connected to the output end of the servo motor 12; A detection component 3 is provided at the top of the base 1. The detection component 3 includes a detection housing 31 on the base 1. The detection housing 31 has a storage tank 301, a conveying tank 302 at the lower end of the storage tank 301, a discharge tank 303 communicating with the conveying tank 302, and a top groove 304 communicating with the discharge tank 303. A stud 310 is fixedly connected to the bottom of the detection housing 31. A servo motor 32 is installed on the outer wall of the detection housing 31. A belt roller 33 is fixedly connected to the output shaft of the servo motor 32. A conveyor belt 34 is connected between the belt rollers 33. A screw hole 102 is provided at the top of the turntable 13 and is threadedly connected to the stud 310. There is a gap between the conveying tank 302 and the conveyor belt 34. A sealing cover 311 is snapped into the upper end of the storage tank 301.

[0024] The servo motors 1 and 2 are powered by an external controller; the detection component 3 is threadedly connected to the screw hole 102 of the turntable 13 via a stud 310, enabling quick assembly and disassembly (the stud 310 needs to be installed on the outer end of the stud with a hollow bolt to strengthen its connection), adapting to the carrying and storage needs of different scenarios; the storage tank 301 is a sealed cavity, with a sealing cover 311 snapped on top to prevent dust and moisture, and is used to stack and store test papers inside, with its tank size matching the test papers to ensure neat stacking; the conveyor belt 34 is made of corrosion-resistant and non-slip material, and a reasonable gap is reserved between the conveyor tank 302 and the conveyor belt 34 to avoid test paper jamming and ensure single-sheet conveying accuracy; the servo motor 12 can precisely control the rotation of the turntable 13 to achieve precise alignment of the test paper and the container tank 201; the stud 310 and the screw hole 102 are fitted on the outer end of the stud 310 through a set internal threaded ring to increase its stability.

[0025] In use, follow the steps in Example 1 to install and fix the sample dish tray 2; tighten the detection component 3 onto the top of the turntable 13 with the studs 310 and screw holes 102, open the sealing cover 311, and neatly stack the test papers into the storage tank 301; start the servo motor 2 32 to drive the belt roller 33 to drive the conveyor belt 34 to rotate slowly, and the bottom layer of test papers moves with the conveyor belt 34 to the end of the conveyor trough 302, and falls accurately into the test dish below through the feeding trough 303; drive the turntable 13 to rotate by the servo motor 1 12, and align each dish trough 201 with the feeding trough 303 in sequence to complete the batch of test paper feeding; after static reaction, observe whether the test paper shows abnormalities such as color change or precipitation to determine the microbial resistance.

[0026] Example 3: The technical solution of this example, which differs from that of Example 1, includes: a support plate 35 is fixedly connected to the lower end of the top groove 304; a liquid storage cylinder 37 is installed at the upper end of the top groove 304; a pump body 36 is fixedly connected to the top center of the support plate 35; a liquid guide head 360 is fixedly connected to the output end of the pump body 36; multiple connecting pipes 361 connected to the inner end of the liquid storage cylinder 37 are fixedly connected to the input end of the pump body 36; a partition plate 38 is fixedly connected to the inner end of the liquid storage cylinder 37; multiple liquid inlet pipes are embedded at the top of the liquid storage cylinder 37; and the liquid inlet pipes and multiple connecting pipes 361 correspond to the chambers between the partition plates 38.

[0027] The liquid storage cylinder 37 is divided into multiple independent sealed chambers by a partition plate 38, which can store antibacterial reagents of different concentration gradients to meet the needs of multiple groups of drug resistance comparison tests. Each chamber corresponds to a set of inlet pipes and connecting pipes 361. The connecting pipes 361 are equipped with independent control valves to accurately switch reagent types. The pump body 36 is a miniature quantitative delivery pump that can accurately control the reagent output to ensure that the reagent dosage is consistent for each group of tests. The liquid guide head 360 has a precise dripping design to avoid reagent splashing and ensure that the reagent falls completely into the test dish.

[0028] In use, different concentrations of target antibacterial reagents are injected into each independent chamber through the corresponding inlet pipe at the top of the storage cylinder 37, and the inlet pipe is sealed after injection. According to the testing plan, the control valve of the connecting pipe 361 of the corresponding concentration reagent chamber is opened, and the pump body 36 is started. The pump body 36 accurately extracts the set dose of antibacterial reagent and delivers it to the liquid guide head 360 through the connecting pipe 361. The liquid guide head 360 drips into the test dish aligned below the feed trough 303. Repeated operation can switch between different concentrations of reagents to perform multiple sets of parallel tests. After the reaction is completed, the resistance of microorganisms to different concentrations of antibacterial reagents can be quickly determined by observing the growth status of microorganisms in the test dish or the changes in the reaction solution.
