Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of medical equipment, in particular to a wet bag rapid detection device for a disinfection supply center. Background Art
[0002] The Central Sterile Supply Department (CSSD) is a medical institution's department responsible for cleaning, disinfecting, sterilizing, and supplying sterile supplies to all reusable medical instruments, instruments, and supplies across all departments. The quality of its work is directly linked to the quality of healthcare and patient safety, making it a key component of hospital-acquired infection control.
[0003] Wet packs are a common problem in sterilization supply centers. Wet packs refer to the appearance of moisture, water droplets, and other conditions in sterilized instrument or item packaging. Research indicates that traditional packaging materials, such as ordinary cotton cloth and medical nonwovens, are prone to wet packing during the sterilization process. For example, the wet rate for an 8kg instrument package wrapped in ordinary cotton cloth can reach 83.33%, while the wet rate for an 11kg instrument package wrapped in medical nonwovens is 50.00%. This not only affects sterilization effectiveness but can also increase the risk of nosocomial infections.
[0004] The work environment at a sterilization and supply center is complex and demanding, handling a large number of medical device packages daily. After sterilization, these packages need to be quickly and accurately transported to a testing area via conveyor equipment for moisture testing. Existing automated testing typically utilizes moisture detection components, such as those described in patent (CN114371092A), which transport the medical device packages to a testing machine for testing.
[0005] However, conveyor equipment can experience vibrations and bumps during operation, especially when the conveyor belt speed is uneven or there are mechanical problems. This can easily cause the instrument bag to shake or collide during transport, leading to loosening. This looseness can directly affect the accuracy of wet bag detection. A loose instrument bag can prevent the detection device from accurately capturing the humidity inside, increasing the possibility of misjudgment.
[0006] In view of the defects of the existing technology, there is an urgent need for a wet bag rapid detection device that can effectively solve the problem of loose instrument bags during transportation. Summary of the Invention
[0007] In order to solve the above problems, the purpose of the present invention is to provide a wet pack rapid detection device for a disinfection supply center, which can ensure the stability of the instrument pack during transportation and avoid inaccurate detection due to looseness.
[0008] In order to achieve the above object, the technical solution of the present invention is as follows:
[0009] A wet pack rapid testing device for a disinfection supply center includes a conveying mechanism, a correcting mechanism, and a testing mechanism; the conveying mechanism is used to transfer the instrument pack to the testing mechanism;
[0010] The correction mechanism includes a pair of bases, which are respectively located on both sides of the conveying mechanism. A first moving mechanism is provided on one side of each base, and the first moving mechanism is used to drive the base to move along the conveying direction; a movable groove is provided on each base, and a pair of pillars are slidably fitted in the movable grooves. A second moving mechanism for driving the pillars to move back and forth is provided in any movable groove, and cross bars are provided between the pillars along the width direction of the conveying mechanism, and telescopic mechanisms are provided between the pillars along the length direction of the conveying mechanism. A flat plate is provided on the cross bar and the telescopic mechanism, and the telescopic mechanism is used to drive the flat plate to retract and extend based on the movement of the pillars;
[0011] The detection mechanism is used to perform multi-dimensional humidity detection on the instrument package.
[0012] The above scheme has the following beneficial effects:
[0013] 1. This solution places the instrument kit to be tested between the flat plates. The second moving mechanism is activated to drive the struts toward each other, thereby bringing the flat plates located at the front and rear of the kit closer to the kit. As the struts approach, the telescopic mechanism pulls the flat plates toward the left and right sides of the kit, adjusting the position of the kit. Once the four sides of the kit are in contact with the flat plates, the first moving mechanism drives the base to follow the conveyor mechanism's direction of movement, escorting the kit all the way to the testing mechanism. The testing mechanism then performs humidity testing.
[0014] In the prior art, the instrument package may become loose or misaligned during transport, resulting in inaccurate test results. However, the present invention, through the design of a correction mechanism, can effectively adjust the position of the instrument package so that it remains stable during transport. Because the stability of the instrument package during transport is guaranteed, the detection mechanism can perform more accurate humidity detection on the instrument package. The flat panel fixes the instrument package in the appropriate position, allowing the detection mechanism to comprehensively and evenly detect the instrument package, avoiding detection blind spots or data deviations caused by improper or loose positioning of the instrument package.
[0015] 2. This solution realizes the automatic transmission and detection of instrument packages through the coordinated work of the transmission mechanism, the adjustment mechanism and the detection mechanism, reduces manual intervention and improves work efficiency.
[0016] 3. This solution can accommodate instrument kits of varying sizes and shapes, demonstrating strong versatility and adaptability. The automated testing process shortens instrument kit processing time and improves the overall efficiency of the sterilization supply center.
[0017] Furthermore, the first moving mechanism includes several side wheels, which are rotatably connected to the side walls of the base respectively; side grooves are opened on the outside of the transmission mechanism, and the side wheels are rollingly engaged with the side grooves; a driving member is provided in any base, and the driving member is used to drive the side wheels to rotate.
[0018] Beneficial Effect: By driving the side wheels with a driver, the base's moving speed and position can be precisely controlled. This ensures that the base always follows the conveying direction of the conveyor during the conveying process, accurately escorting the instrument package to the testing facility.
[0019] Furthermore, the second moving mechanism includes a brushless motor and a cylinder. The brushless motor is used to drive the cylinder to rotate. The other end of the cylinder is rotatably connected to the movable groove. Spiral grooves are symmetrically opened on the cylinder. The spiral grooves are slidably fitted with protrusions, and the protrusions are fixedly connected to the pillars respectively.
[0020] Beneficial Effects: A brushless motor drives the cylinder, and the spiral grooves on the cylinder cooperate with the protrusions to precisely control the movement of the pillars. The forward and reverse rotation of the brushless motor precisely adjusts the position of the pillars, allowing the platform to accurately gather, fit, or release the instrument pack, ensuring optimal positioning of the pack during transport.
[0021] Furthermore, the telescopic mechanism includes a telescopic clamp; the output end of the telescopic clamp is hinged to the flat plate, and the input ends of the telescopic clamp are respectively hinged to the pillars.
[0022] Beneficial Effects: The output end of the telescopic clamp is hinged to the flat panel, while the input end is hinged to the support. This connection allows the telescopic mechanism to flexibly extend and retract according to the movement of the support. As the support moves closer or further away from each other, the telescopic clamp can correspondingly move the flat panel toward or away from the instrument bag, thereby enabling flexible adjustment of the instrument bag's position.
[0023] Furthermore, the detection mechanism includes a detection part, a detection platform and a collection frame; the detection part is located above the detection platform, and a receiving cavity is provided at the bottom of the detection part. A detection cover and an electric cylinder are provided in the receiving cavity. The detection cover and the receiving cavity are slidably matched. The electric cylinder is used to drive the detection cover to rise and fall. A moisture detection unit is provided in the detection cover. The moisture detection unit is used to collect the humidity in the instrument package;
[0024] The top of the test bench is rotatably connected to a number of pendulum discs, and the bottom of each pendulum disc is provided with a rotating member for driving the pendulum disc to rotate; each pendulum disc is provided with a number of rollers and a power member for driving the rollers to rotate; a cushion layer is provided at the top center of the test bench, and a pressure sensor is provided at the bottom of the cushion layer; a hot air component is provided inside the test bench, and the hot air component is used to deliver hot air to the inside of the test cover;
[0025] The collection box is used to collect instrument packages that are determined to be wet packages;
[0026] It also includes a control unit, which is electrically connected to the hot air component and the electric cylinder respectively. The control unit is used to comprehensively judge the humidity condition of the instrument package based on the humidity condition and pressure data, and control the operation of the power part and the rotating part.
[0027] Beneficial effect: When the instrument package is transported to the cushion layer on the inspection table by the conveying mechanism, the pressure sensor can detect the initial pressure of the instrument package at this time, and then start the electric cylinder to make the electric cylinder cover the instrument package with the inspection cover, and then start the hot air component to increase the temperature of the instrument package covered by the inspection cover, and evaporate the moisture in the instrument package. At this time, the humidity in the instrument package is collected by the moisture detection group unit. After a preset period of time, the pressure of the instrument package is re-collected through the pressure sensor. The control unit determines whether the instrument package is a wet package based on the humidity and pressure changes during the whole process. If it is a wet package, the power part and the rotating part are controlled to turn the wet package to the collection frame on one side for separation.
[0028] The testing unit accurately measures the humidity inside the instrument bag through a moisture detection unit. Simultaneously, a pressure sensor detects changes in pressure during the testing process. This multi-dimensional data collection method provides a comprehensive basis for determining whether the instrument bag is wet, ensuring the accuracy and reliability of the test results.
[0029] The control unit, at its core, intelligently determines the humidity status of the instrument bag based on collected multi-dimensional data (humidity and pressure). Once a wet bag is identified, the system automatically controls the operation of the power and rotating components to transfer the wet bag to a collection frame without human intervention. This fully automated detection and processing process significantly improves work efficiency and reduces labor costs and error rates.
[0030] The hot air component provides additional support for the testing process. By pumping hot air into the test hood, the temperature of the instrument package increases, evaporating the moisture inside and facilitating detection by the moisture collection unit. This auxiliary detection method further enhances the accuracy of the instrument package's humidity assessment, resulting in more scientific and reliable test results.
[0031] Furthermore, a buffer groove is provided on one side of the flat plate close to the instrument bag, an inner plate is slidably connected in the buffer groove, and a plurality of springs are provided between the inner plate and the flat plate.
[0032] Beneficial Effect: When the instrument bag contacts the flat surface, the inner plate slides within the buffer groove, working in conjunction with the spring force to effectively absorb the collision energy and mitigate the impact between the instrument bag and the flat surface. This not only protects the instrument bag from damage due to collisions, but also reduces vibration during transport, ensuring the instruments within the bag remain intact.
[0033] Furthermore, a plurality of cavities are arranged in an array on one side of the inner plate close to the instrument package, and a convex film layer, a thin sheet and parallel capacitor plates are provided in the cavities. The capacitor plates are electrically connected to the control unit. The convex film layer is used to respond to the contact of the instrument package, and the thin sheet is used to interfere with the capacitance between the capacitor plates based on the change of the convex film layer; the control unit is also used to judge the change of the contact area between the instrument package and the inner plate based on the change of capacitance, and to judge the looseness of the instrument package based on the change of contact area.
[0034] Beneficial Effect: When the instrument pack contacts the inner plate, the convex membrane layer deforms in response to the pack's contact pressure, causing the thin film to move, changing the distance or coverage between the capacitor plates and disrupting their capacitance. By monitoring these changes in capacitance, the control unit accurately determines changes in the contact area between the instrument pack and the inner plate. This design provides high-resolution contact area detection, sensitively capturing any slight displacement or deformation of the instrument pack during transport and testing.
[0035] Based on the precise monitoring of changes in contact area (the tightness of the instrument package can reflect the degree of deformation, and the flat plate / inner plate must first compress the wrapped gap before the instrument package can be pushed to move), the control unit can further determine whether the instrument package is loose. If the instrument package becomes loose during transmission, its shape and contact area will change accordingly. This change will be captured in time by the capacitor plate and converted into a capacitance signal. The control unit can accurately identify whether the instrument package is loose by analyzing the change pattern of these signals, and then filter out the instrument package that was loose before transmission. The control unit integrates the capacitance change data with other detection data, and makes a comprehensive judgment through intelligent algorithms, thereby improving the intelligence level of the entire detection system. This multi-dimensional data analysis can more comprehensively and accurately evaluate the status of the instrument package.
[0036] Furthermore, the control unit is also used to preliminarily determine the cause of the wet package based on the looseness of the instrument package; if the instrument package is loose and the control unit determines that it is a wet package, it is determined that there is a loose defect in the instrument package during the packaging process, resulting in the internal moisture not being effectively discharged; if the instrument package is not loose and the control unit determines that it is a wet package, it is determined that the wet package is caused by the high humidity in the transmission environment.
[0037] Beneficial Effects: This comprehensive assessment, based on looseness and humidity test results, enables a more comprehensive analysis of the causes of wet packs, providing precise feedback for subsequent quality control and process optimization. By distinguishing different situations, targeted improvement measures can be taken, such as adjusting the packaging process, optimizing humidity control, or improving storage conditions, effectively reducing the occurrence of wet packs and improving the overall quality and efficiency of the sterilization supply center.
[0038] Furthermore, the control unit is used to control the operation of the power part and the rotating part based on the looseness of the instrument package.
[0039] Benefits: The quality of instrument packs is crucial in sterilization and supply centers. The control unit monitors the looseness of instrument packs and controls the operation of the power and rotating components accordingly, promptly identifying loose instrument packs and removing them from the transport path. This ensures that only well-packaged instrument packs are transported and used, improving the safety and reliability of the entire medical process and avoiding medical risks caused by loose instrument packs.
[0040] Furthermore, the hot air component includes an air cavity; the air cavity is connected to the outside world, and an electric heating pipe and a fan are provided on the path connecting the air cavity and the outside world. The fan is used to transport outside air into the air cavity, and the electric heating pipe is used to heat the air. A number of air outlets are connected to the top of the air cavity; the electric heating pipe and the fan are both electrically connected to the control unit.
[0041] Beneficial Effects: During the test, a fan draws outside air into the air chamber, where the electric heating tube heats the air. This heated air is then delivered to the interior of the test hood through the air outlet. This heated air raises the temperature of the instrument package, evaporating moisture within and dissipating some heat, causing temperature fluctuations. The control unit analyzes these temperature and humidity fluctuations to more accurately determine whether the instrument package is wet. This auxiliary heating design enhances the scientific nature and reliability of the test, ensuring the authenticity and accuracy of the test results. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] The control unit controls the electric cylinder 101 to operate, so that the detection cover 102 covers the instrument package in the detection cavity 103, and then starts the electric heating tube, the fan 402, the semiconductor refrigeration plate and the microwave moisture detector 1041. The control unit uses the microwave moisture detector 1041 to collect the humidity change in the absorbent cotton 1042 during this process (this reflects the moisture content in the instrument package, that is, the humidity inside the instrument package). After a preset time, the control unit stops the operation of the electric heating tube and the fan 402. At this time, the control unit again obtains the second pressure information collected by the pressure sensor 601;
[0070] When the humidity exceeds a preset humidity threshold, the control unit determines that the device bag is a wet bag;
[0071] When the difference between the first pressure information and the second pressure information exceeds a preset difference, the control unit determines that the device bag is a wet bag;
[0072] Then, the servo motor 502 is controlled to rotate the pendulum wheel 5 so that the rolling direction of the roller 501 is aligned with the collection frame 3, and then the AC motor is started to rotate the roller 501 to transfer the wet bag to the collection frame 3 for the next step of processing.
[0073] Preferably, it also includes an interactive interface (not shown in the figure), which is used to display the judgment result of the control unit; the control unit is also used to preliminarily judge the cause of the wet pack based on the looseness of the instrument package; if the instrument package is loose (based on the precise monitoring of the change in contact area (the tightness of the instrument package can reflect the degree of deformation, and the flat plate / inner plate must first compress the wrapped gap before pushing the instrument package to move), the control unit can further judge whether the instrument package is loose. If the instrument package becomes loose during the transmission process, its shape and contact area will change accordingly, and this change will be captured by the capacitor plate in time and converted into a capacitance signal. The control unit can accurately identify whether the instrument package is loose by analyzing the change pattern of these signals), and the judgment result of the control unit is a wet pack, then it is judged that the instrument package has a loose defect during the packaging process, resulting in the failure to effectively discharge the internal moisture; if the instrument package is not loose, and the judgment result of the control unit is a wet pack, then it is judged that the wet pack is caused by the high humidity in the transmission environment.
[0074] The specific implementation process is as follows: Take the wet pack test of a batch of surgical instrument packages conducted by a hospital's disinfection supply center as an example:
[0075] The surgical instrument kit to be inspected is manually placed at the starting end of conveyor mechanism 2 (the area between the flat plates 703), and conveyor mechanism 2, the first moving mechanism, and the second moving mechanism are activated. A DC motor rotates the side wheels 704, causing the entire alignment mechanism to follow the movement of the transmission mechanism. Simultaneously, a brushless motor 7063 rotates the cylinder 7061, which in turn drives the protrusion 7064 along the spiral groove 7062, thereby moving the struts 701 closer together. As the struts 701 move closer together, they squeeze the retractable clamps 702, gradually bringing the flat plates 703 of the instrument kit closer together.
[0076] During contact between the flat plate 703 and the instrument pack, the inner plate 7031 within the buffer slot 7037, acting under the action of spring 7036, absorbs the collision energy, reducing the impact force on the instrument pack. Simultaneously, the convex membrane layer 7032 on the inner plate 7031 deforms in response to the contact pressure of the instrument pack, moving the thin plate 7034 and changing the capacitance between the capacitor plates 7035. By monitoring this capacitance change, the control unit determines the change in contact area between the instrument pack and the inner plate 7031, and thus determines whether the instrument pack is loose.
[0077] When the instrument package moves to the detection part 1, the stepper motor 7011 drives the screw 7012 to rotate, the screw 7012 drives the nut seat 7013 to move, and the nut seat 7013 drives the cross bar 705 to move upward, thereby allowing the instrument package to break away from the restriction of the flat plate 703 and enter the pad 6 between the detection table 4 and the detection part 1.
[0078] The instrument package is placed on the cushion layer 6 of the testing platform 4. The pressure sensor 601 detects the first pressure information of the instrument package, i.e., the initial pressure. The electric cylinder 101 then drives the testing cover 102 downward, covering the instrument package. The hot air assembly is activated, delivering hot air into the testing cover 102, raising the temperature of the instrument package and causing the internal moisture to evaporate. The water vapor rises until it enters the spiral conduit 1043 and the testing channel 104. As the water vapor flows within the spiral conduit 1043, centrifugal force causes it to contact the semiconductor cooling plates on the sidewalls of the spiral conduit 1043, cooling it. This provides a stable, cooler temperature field for subsequent microwave moisture detector 1042 detection, preventing high-temperature air from affecting the moisture detection of the microwave moisture detector 1042. The water vapor liquefies and enters the absorbent cotton 1042 along with the air. The microwave moisture detector 1041 then monitors the changes in moisture content within the absorbent cotton 1041 in real time. After a preset period of time, the pressure sensor 601 re-collects the pressure of the instrument package.
[0079] The control unit analyzes changes in temperature, humidity, and pressure throughout the entire process to determine whether the instrument package is wet. If so, the control unit preliminarily determines the cause of the wetness based on the looseness of the instrument package and displays this information on the interactive interface. If the instrument package is loose, the wetness is determined to be due to looseness defects during the packaging process. If the instrument package is not loose, the wetness is determined to be due to high humidity in the transmission environment. Based on this determination, the control unit controls the operation of the servo motor 502 and the AC motor to transfer the wet package to the collection frame 3 for further processing.
