Description

Technical Field

[0001] This utility model relates to the field of sterilizer technology, and more specifically, to a rapid reader for sterilizers. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] In the field of medical sterilization, plasma sterilizers, rapid readers, and bioincubators are commonly used equipment. Currently, there are generally two methods for detecting microbial viability: conventional microbial viability detection and biological indicator detection. One principle of biological indicator detection is to utilize the excrement produced by microorganisms during their survival and metabolism to alter the pH of specific components of the culture medium, thereby changing the color of the culture medium. This color change can be observed directly with the naked eye, without the need for a microscope, making the detection process simpler and faster.

[0004] While existing plasma sterilizers may be equipped with rapid readers, they can only culture and read indicators specific to that device. If a hospital department has multiple sterilizers of different models and lacks a compatible reader, it cannot promptly culture and monitor the indicators. The rapid readers on typical existing plasma sterilizers can only detect biological indicators for a specific type of microorganism. Currently, there is a market need for a sterilizer capable of simultaneously detecting biological indicators from multiple microbial samples to improve testing efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, the present invention aims to provide a rapid reader for sterilizers, capable of simultaneously detecting multiple corresponding microbial samples for sterilization using biological indicators, thereby greatly improving detection efficiency.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] This utility model provides a rapid reader for sterilizers, comprising:

[0008] case;

[0009] The control unit is housed within the casing;

[0010] The reagent tube includes a flexible tube shell, a fragile separator, and a bacterial strip. The fragile separator is located inside the flexible tube shell and seals the flexible tube shell into an upper chamber and a lower chamber. The bacterial strip is located in the lower chamber, and an indicator is located in the upper chamber.

[0011] The carrier has a crushing groove and multiple culture tanks; the reagent tube can be inserted into the crushing groove and can crush the fragile insulator within the crushing groove; the reagent tube can be inserted into any culture tank for culture; each culture tank has a switch hole and a detection hole.

[0012] Limit switch, the limit switch is set in the switch hole, the limit switch is electrically connected to the control unit, the limit switch is triggered when the reagent tube is inserted into the culture tank, and the trigger signal is sent to the control unit;

[0013] The identification component includes a fixture, LED beads, and a light sensor. Both the LED beads and the light sensor are electrically connected to the control unit. The fixture is provided with a light emission channel and a light reception channel, both of which are connected to the culture tank. The LED beads are placed in the light emission channel and send corresponding light to the culture tank. The light sensor is placed in the light reception channel and acquires the light from the culture tank.

[0014] The information scanning device is housed inside the housing and electrically connected to the control unit. The housing has a scanning port, and the scanning end of the information scanning device is connected to the scanning port.

[0015] The printer is housed within a casing with a report output port. The printer's signal input terminal is electrically connected to the control unit, and the printer's output terminal is connected to the report output port.

[0016] Furthermore, the crushing trough is equipped with protrusions, and the reagent tube is crushed by the pressure of the protrusions.

[0017] Furthermore, there are multiple protrusions, which are symmetrically distributed along the sidewall of the pulverizing trough.

[0018] Furthermore, the switch hole is located directly above the detection hole. When the reagent tube is inserted into the culture tank, the limit switch located at the switch hole is triggered first, and then the detection hole is reached.

[0019] Furthermore, the detection hole is located at the bottom of the corresponding culture tank.

[0020] Furthermore, the angle between the light emission channel and the light receiving channel is an acute angle.

[0021] Furthermore, each culture tank is equipped with a heating element for heating reagent tubes, and the heating element is electrically connected to the control unit.

[0022] Furthermore, the housing is provided with a placement opening, and a baffle is provided on the placement opening, with the baffle being rotatably connected to the inner sidewall of the placement opening.

[0023] Furthermore, it also includes: in response to the triggering of the limit switch, the control unit controls the lamp to light up and activates the light sensor, the lamp illuminates the reagent tube; the light sensor detects the reflected light from the reagent tube and sends the detected signal to the control unit.

[0024] In summary, the technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0025] This invention utilizes a crushing tank to break down fragile insulators. At this point, the fragile insulators no longer function as insulators, and the indicator mixes with the corresponding sterilized sample. The flexible tube shell is then placed into a corresponding culture tank. After incubation in the designated environment, changes in the physical or chemical properties within the test tube can be detected by a recognition component, allowing for the assessment of microbial survival and thus verifying the sterilization effect. Because multiple culture tanks are provided, multiple fragile insulators with flexible tube shells can be crushed simultaneously. For different sterilized samples, the corresponding indicator can be placed inside the flexible tube shell. For example, different flexible tube shells containing indicators such as hydrogen peroxide, vapor, ethylene oxide, and formaldehyde can be used for different sterilized samples. After sterilization, each flexible tube shell is crushed and placed in a different culture tank, providing its respective incubation environment. The results are then detected by the recognition component. This allows for the simultaneous detection of multiple corresponding sterilized microbial samples using biological indicators, significantly improving detection efficiency.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] like Figure 1 As shown in the figure, the core function of the rapid reader for sterilizers proposed in this embodiment of the present invention is to verify the sterilization effect through an automated process. The housing 1 is made of 6061 aluminum alloy engineering plastic, and its internal layout is divided into three functional modules: a control area, a detection area, and an output area. This compact design ensures both the strength of the equipment and ease of placement in the laboratory. Meanwhile, to protect the reagent tubes, the housing 1 has a placement opening with a baffle plate, which is rotatably connected to the inner wall of the placement opening.

[0034] The control unit is located inside the housing 1. It can use an STM32F407 microcontroller as the main control chip or other types of PCB control boards. It communicates with each functional module through the CAN bus to realize the timing control of the entire detection process. This design significantly improves the system response speed and processing capacity.

[0035] like Figure 5 As shown, the reagent tube includes a flexible outer shell 2, a fragile separator 3, and a bacterial strip 4. The fragile separator 3 is disposed inside the flexible outer shell 2, sealingly dividing the flexible outer shell 2 into an upper chamber 5 and a lower chamber 6. The bacterial strip 4 is disposed in the lower chamber 6, and the upper chamber 5 contains an indicator 7. In other words, it adopts a double-layer cavity structure. The flexible outer shell 2 is made of transparent polycarbonate, and the fragile separator 3 is made of fragile glass. This design ensures both airtightness and ease of mechanical breakage. The bacterial strip 4 uses Bacillus stearothermophilus as the biological indicator 7 and is placed in the lower chamber 6. The upper chamber 5 is filled with a pH-sensitive liquid indicator 7. When the separator breaks, the liquids in the two chambers mix and produce a color reaction.

[0036] The support member 8 is provided with a crushing groove 9 and multiple culture tanks 10, such as Figure 3 As shown, the reagent tube can extend into the homogenizing tank 9 and can crush the fragile isolation body 3 within the homogenizing tank 9. The reagent tube can also extend into any culture tank 10 for cultivation. Each culture tank 10 has a switch hole 18 and a detection hole 19. The support component 8 is made of ABS engineering plastic and has 7 circular culture tanks 10 and 1 homogenizing tank 9. All the tanks are arranged in a straight line, which optimizes space utilization and facilitates quick positioning by the operator.

[0037] Limit switches, such as Figure 2 As shown, a limit switch is disposed within the switch hole 18. The limit switch is electrically connected to the control unit. The limit switch is triggered when the reagent tube is inserted into the culture tank 10, and a trigger signal is sent to the control unit. Specifically, the limit switch can be an Omron D2F series micro switch or other limit switches, installed in the switch hole 18 on the side wall of the culture tank 10. When the reagent tube reaches the preset insertion depth, a trigger signal is activated, and the control unit immediately starts the detection program for the corresponding tank position.

[0038] The identification component includes a fixture 11, an LED bead 12, and a light sensor 13. Both the LED bead 12 and the light sensor 13 are electrically connected to the control unit. The fixture 11 is provided with a light emission channel 111 and a light receiving channel 112, both of which are connected to the culture tank 10. The LED bead 12 is disposed in the light emission channel 111 and sends corresponding light to the culture tank 10. The light sensor 13 is disposed in the light receiving channel 112 and acquires the light from the culture tank 10. Specifically, the identification component adopts a modular design. The fixture 11 is an aluminum alloy CNC machined part, which integrates an OSRAM SFH4550 infrared LED bead 12 and an AMS TCS34725 light sensor 13. It achieves accurate capture of the color change of the culture medium through a preset optical path channel, with a detection accuracy of ±2nm wavelength resolution.

[0039] The information scanning device 15 is housed within the casing 1 and electrically connected to the control unit. A scanning port is provided on the casing 1, and the scanning end of the information scanning device 15 is connected to this port. Specifically, the information scanning device 15 uses a Honeywell 1900 series QR code scanner head, which can automatically identify the sterilization batch information on the reagent tube label and bind and store it with the test data. For example... Figure 4 As shown, printer 14 is housed within housing 1, which has a report output port. The signal input terminal of printer 14 is electrically connected to the control unit, and the output terminal of printer 14 is connected to the report output port. Printer 14 is an Epson TM-T88VI thermal receipt printer, capable of outputting standardized reports containing sterilization parameters, test results, and operator information in real time.

[0040] The device operates on a complete automated detection chain: The operator first inserts the reagent tube into the crushing tank 9, where mechanical pressure breaks the insulator. The indicator 7 then contacts the bacterial strip 4 and is transferred to the culture tank 10. After the limit switch is triggered, the control unit initiates constant-temperature incubation according to a preset program (typically set at 56±2℃). Simultaneously, the reader is activated for identification. Identification is divided into ordinary identification and ultraviolet (UV) identification. Ordinary identification uses LED beads 12 (ordinary LED beads) and a light sensor 13 to monitor color changes in real time. When the light sensor 13 detects a change in characteristic wavelength (e.g., from red to yellow), it indicates incomplete sterilization, and the system immediately outputs a warning report via printer 14. UV identification, on the other hand, uses UV LED beads to emit UV light of a specific wavelength. When this light shines on the indicator containing fluorescent material, electrons in the indicator molecules absorb the UV light energy and transition to an excited state. When the electrons return to the ground state, they reflect fluorescence. The reader's photoelectric sensor (which can directly replace the original light sensor) accurately detects the emitted fluorescence intensity. After filtering out stray UV light through a filter, the light signal is converted into an electrical signal. The system compares the fluorescence value with a preset standard range to determine whether sterilization is complete.

[0041] Its beneficial effects lie in the integration of functions, combining crushing, culturing, detection, and recording into a single device, avoiding the contamination risks caused by multiple transfers in traditional methods. Secondly, it enables intelligent detection, replacing manual interpretation with a light sensor 13, eliminating subjective errors and significantly improving the traceability of test results. Finally, it standardizes operations, automating the entire process from barcode scanning to report printing, greatly reducing the technical requirements for operators and improving the ease of use for primary healthcare institutions.

[0042] Overall, the reagent tube directly carries the bacterial strip 4 and indicator 7, while the flexible outer shell 2 isolates it from the external environment and holds both the indicator 7 (containing a culture medium) and the bacterial strip 4 with the sterilized sample. The indicator 7 and the bacterial strip 4 with the sterilized sample are isolated by a fragile isolator 3. During sterilization, after the reagent tube is placed into the sterilizer, the fragile isolator 3 isolates the indicator 7 and the sterilized sample, serving only a sterilization function. To test the sterilization effect, after sterilization, the reagent tube is removed and the biological indicator 7 is tested. Specifically, the fragile isolator 3 is broken using a mortar 9. At this point, the fragile isolator 3 no longer serves an isolation function, and the indicator 7 mixes with the corresponding sterilized sample. The flexible outer shell 2 is then placed into the corresponding culture tank 10. After incubation in the culture environment, the changes in physical or chemical properties within the test tube can be identified by the recognition component, allowing for the determination of microbial survival and thus verifying the sterilization effect. Because multiple culture tanks 10 are provided, and multiple fragile isolators 3 with flexible tube shells 2 can be crushed simultaneously, indicators 7 corresponding to different sterilized samples can be placed inside the flexible tube shells 2. For example, for different sterilized samples, flexible tube shells 2 containing indicators 7 such as hydrogen peroxide, vapor, ethylene oxide, and formaldehyde can be used respectively. After sterilization, each flexible tube shell 2 is crushed and placed in a different culture tank 10, providing its corresponding culture environment for incubation. Identification is then performed using a recognition component. In this way, multiple corresponding sterilized microbial samples can be detected simultaneously using biological indicators 7, greatly improving detection efficiency.

[0043] like Figure 2 As shown, further, the crushing tank 9 is provided with a boss 901, and the reagent tube is crushed by the squeezing of the boss 901.

[0044] Specifically, the core of this design lies in achieving directional breakage of the fragile separator 3 through mechanical interference. When the operator vertically inserts the reagent tube into the crushing trough 9, the outer wall of the reagent tube first contacts the top of the boss 901. Under continuous downward pressure, the boss 901 generates concentrated stress on the reagent tube locally. The working principle needs special explanation here: because the flexible outer shell 2 of the reagent tube is made of transparent polycarbonate with elastic deformation capabilities, while the fragile separator 3 is made of brittle glass, when the compressive force applied by the boss 901 is transmitted through the flexible outer shell 2 to the internal fragile separator 3, the stress rapidly concentrates at the weak points of the glass structure (such as pre-cut stress lines), instantly exceeding its strength limit and causing directional breakage. This allows for the controlled mixing of the pH indicator 7 in the upper chamber 5 and the thermophilic Bacillus stearothermophilus tablet 4 in the lower chamber 6.

[0045] Furthermore, such as Figure 3As shown, there are multiple bosses 901, which are symmetrically distributed along the sidewall of the pulverizing groove 9.

[0046] In the internal structure of the crushing tank 9, the original single protrusion 901 design has been improved to multiple protrusions 901 symmetrically distributed along the sidewall of the tank (e.g., two protrusions 901 evenly distributed in a ring). The core principle of this design lies in optimizing the stress transmission path through a geometrically symmetrical mechanical structure—when the operator inserts the reagent tube vertically into the crushing tank 9, multiple protrusions 901 simultaneously contact the flexible outer shell 2 of the reagent tube circumferentially, forming a uniformly distributed radial compressive force. This multi-directional synchronous force application mode causes the flexible outer shell 2 to produce uniform elastic deformation, forcing the internal fragile insulating body 3 (brittle glass material) to simultaneously bear composite stresses from multiple directions. Since brittle materials are more prone to penetrating fractures at pre-set weak points (such as ring-shaped indentations) under uniform confining pressure, the symmetrical layout of multiple protrusions 901 significantly reduces the risk of glass fragment residue caused by local stress concentration.

[0047] Furthermore, such as Figure 2 As shown, the switch hole 18 is positioned directly above the detection hole 19. During the insertion of the reagent tube into the culture tank 10, the limit switch 17 located in the switch hole 18 is triggered first, and then the reagent tube reaches the detection hole 19. The switch hole 18 is positioned directly above the detection hole 19, meaning that in the vertical direction of the culture tank 10, the switch hole 18 is located above the detection hole 19, forming a vertically aligned layout. As the reagent tube extends into the culture tank 10, it first contacts and triggers the limit switch 17 located within the switch hole 18, and then continues to move downwards to the detection hole 19, thus ensuring strict timing control of the operation sequence. This design, through spatial optimization, achieves a sequential triggering of events; that is, the activation of the limit switch 17 occurs before the reagent tube reaches the detection hole 19, providing a reliable signal for the initiation of subsequent detection procedures.

[0048] Specifically, the arrangement of the switch hole 18 directly above the detection hole 19 utilizes the vertical insertion path characteristics caused by gravity. When the reagent tube is inserted vertically into the culture tank 10, its top or sidewall will preferentially pass through the area of ​​the switch hole 18, where it will collide with the trigger rod of the limit switch 17, activating the limit switch 17 and immediately sending a trigger signal to the control unit. Subsequently, the reagent tube continues to descend under continuous downward pressure, eventually being precisely positioned at the detection hole 19. At this point, the LED bead 12 of the identification component can project light into the culture tank 10 through the light emission channel 111, while the light sensor 13 captures the reflected light in the culture tank 10 through the light receiving channel 112 to monitor the color change of the indicator 7 in real time. The principle of this sequential operation lies in the mechanical interference timing formed by the difference in spatial position: the limit switch 17 serves as the starting point trigger signal, which the control system uses to initiate the culture and monitoring program, while the detection hole 19 performs the actual optical detection in subsequent steps, avoiding detection interruption or data distortion caused by the reagent tube not being fully in place. The trigger depth of the limit switch 17 is preset to be higher than the position of the detection hole 19, and the detection hole 19 is located at the bottom of the corresponding culture tank 10. This ensures that optical detection is activated only after the reagent tube is correctly inserted and stabilized, thereby improving the system's anti-interference capability.

[0049] Furthermore, such as Figure 2 As shown, the angle between the light emitting channel 111 and the light receiving channel 112 is an acute angle.

[0050] In the optical path design of the identification component, the central axes of the light emitting channel 111 and the light receiving channel 112 are arranged at an acute angle (α), typically ranging from 30° to 60°. Specifically, the light emitting channel 111 inside the fixture 11 extends at an angle, with its outlet facing the reagent tube detection area within the culture tank 10. Correspondingly, the inlet of the light receiving channel 112 is offset at the same acute angle, ensuring that the photosensitive surface of the light sensor 13 forms a non-perpendicular receiving relationship with the incident light. For example, when the infrared light emitted by the lamp bead 12 illuminates the outer wall of the reagent tube within the culture tank 10 at a 45° angle through the emitting channel, the reflected / transmitted light will propagate at the complementary angle of the law of reflection (i.e., a 135° reflection angle). At this time, the 45° tilt angle of the receiving channel precisely captures the main energy region of the reflected light.

[0051] This design is based on the principle of reflection suppression and effective signal enhancement in optical detection. When light is incident on the surface of the culture medium at an acute angle, specular reflection interference can be significantly reduced (Fresnel's law of reflection states that the intensity of specular reflection increases exponentially with the increase of the incident angle), while the diffuse reflection signal (containing the color information of the culture medium) is not significantly affected by the angle due to its isotropic nature. At the same time, the acute angle layout allows the receiving channel to avoid the direct path of the light source, effectively blocking direct reflected light from the walls or surface of the culture tank 10 (such stray light wavelengths overlap with the characteristic signal). Taking a 45° angle as an example: if specular reflection occurs in the liquid in the culture tank 10, its reflected light path will escape along the 90° direction (symmetrical with the incident light), while the light sensor 13 is located in an asymmetrical position due to the 45° tilt of the receiving channel, and can only capture the diffuse reflected light scattered by the particles of the culture medium. This light carries the true color characteristic information (such as the wavelength shift caused by pH changes), thereby improving the anti-interference capability.

[0052] Furthermore, such as Figure 1 As shown, any culture tank 10 is also equipped with a heating element 16 for heating reagent tubes, and the heating element 16 is electrically connected to the control unit.

[0053] Based on the existing culture tank 10 structure, an embedded heating element 16 is integrated inside each independent culture tank 10. This heating element 16 uses a thin-film electric heating element (such as a polyimide etched heating plate) tightly attached to the metal cavity wall of the culture tank 10. The heating element 16 is directly connected to the temperature control circuit of the control unit via a cable, and the power output is adjusted in real time by a microcontroller (such as an STM32F407). During operation, the heating element 16 converts electrical energy into heat energy, which is conducted through the 304 stainless steel tank wall to create a uniform constant temperature environment inside the culture tank 10. For example, for the cultivation requirements of thermophilic Bacillus stearothermophilus, the control unit can accurately maintain the temperature inside the tank at a set value of 56±0.3℃. The principle is that the microcontroller continuously collects the temperature signal of the PT1000 platinum resistance thermometer buried at the bottom of the tank and dynamically adjusts the PWM duty cycle through a PID algorithm to eliminate the influence of ambient temperature fluctuations.

[0054] Furthermore, in response to the triggering of the limit switch, the control unit controls the LED bead 12 to light up and activates the light sensor 13, causing the LED bead 12 to illuminate the reagent tube. The light sensor 13 detects the reflected light from the reagent tube and sends the detected signal to the control unit. In other words, when the reagent tube is vertically inserted into the culture tank 10 to a preset depth, the limit switch fixed in the switch hole 18 is triggered by the mechanical compression of the reagent tube's sidewall, generating an electrical signal trigger event. This trigger signal is transmitted to the control unit in real time via a cable, indicating that the reagent tube has completed its physical positioning and entered the inspection state.

[0055] In summary, the operator inserts a flexible reagent tube containing a bacterial tablet 4 (lower chamber 6) and a pH-sensitive indicator 7 (upper chamber 5) into the mixing tank 9. Symmetrically distributed protrusions 901 within the tank exert concentrated stress on the flexible outer shell of the reagent tube, causing the fragile glass separator inside to break in a directional manner, thus promoting liquid mixing in the upper and lower chambers 6. The reagent tube is then transferred to the culture tank 10. Upon insertion, the reagent tube first triggers the limit switch on the upper switch hole 18, prompting the control unit to initiate the program: activating the embedded heating element 16 to maintain a constant temperature culture environment of 56±0.3℃, while simultaneously controlling the LED bead 12 to project light at a preset acute angle towards the detection hole 19. The light sensor 13 simultaneously captures the diffuse reflected light from the reagent tube. If microbial survival during the culture process causes pH changes, triggering a colorimetric reaction, the sensor identifies the characteristic wavelength shift in real time. The control unit determines sterilization failure and drives the Epson printer 14 to output a warning report. The entire process is automatically linked to sterilization batch information via a barcode scanner, enabling data traceability.
