Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to a device for detecting and identifying contaminants inside tubular instruments. Background Technology

[0002] In recent years, with the development and progress of medical technology and medical equipment, the application of luminal instruments in clinical diagnosis and treatment has become more and more widespread. The cleaning quality of luminal instruments directly affects the subsequent disinfection or sterilization effect. If the cleaning quality is not up to standard, it will lead to disinfection or sterilization failure, which in turn will lead to the risk of infection events. Therefore, it is crucial to check the cleaning of luminal instruments.

[0003] Lumen-type instruments refer to medical devices containing a lumen with a diameter ≥2cm. They generally indicate that the device has a "tube" or "cavity" in its structure. Because of the lumen, some internal structures cannot be properly observed, and it is impossible to guarantee complete cleaning during the initial cleaning process. Common testing methods include occult blood test strips, protein residue tests, and ATP tests; however, these methods are not only time-consuming but also relatively expensive.

[0004] Existing technology, such as the patent document with authorization announcement number CN218629578U, discloses a lumen detection device for lumen-type medical devices, including: an insert, an illumination system, a control system, an operating handle, and a wireless communication module. The insert is used to insert into the lumen of the lumen-type medical device; the illumination lens of the illumination system is located at the first end of the insert to provide a light source; the objective lens of the control system is located at the first end to acquire an image inside the lumen; the operating handle is connected to the second end of the insert; and the wireless communication module is located on the operating handle to send the image to a terminal device for observation of the image using the terminal device.

[0005] When in use, the aforementioned detection device inserts the inserter into the cavity, uses the control system to acquire images of the cavity, and outputs the images to the terminal device via a wireless communication module, thus presenting the internal state of the cavity intuitively and enabling visualization of the cavity, facilitating direct observation of the cavity's internal state through visual means.

[0006] However, when the testing requirements only require pre-testing of the inner wall of the lumen at the port, the design of the operating handle and wire insert of this testing device means that multiple lumen instruments can only be tested one by one by medical staff by holding the first end of the insert. This testing method is inefficient and lacks intelligence. Summary of the Invention

[0007] The purpose of this invention is to solve the problem of low efficiency in existing manual detection methods and improve the pre-detection speed of the inner wall of the lumen at the port. This invention provides a highly automated and efficient device for detecting and identifying contaminants inside lumen instruments.

[0008] To address the above problems, the present invention provides the following technical solution: A device for detecting and identifying contaminants inside tubular instruments, comprising: A detection component for detecting the presence of contaminants inside a tubular instrument, the detection component including a detection tip; Transmission components are used to carry and transport tubular instruments; The direction of the linear reciprocating motion of the probe tip is parallel to the axial direction of each lumen instrument in space, and when the lumen instrument is in the detection state at the current moment, the probe tip can freely enter and exit the lumen instrument.

[0009] In one embodiment, the detection component further includes a carrier tube and a control system, wherein the detection end is disposed at the front end of the carrier tube in the direction of travel, and the detection end is electrically connected to the control system; The carrier tube is mounted at the output end of the drive source one via a connector, and the drive source one drives the carrier tube one to perform linear reciprocating motion.

[0010] In one embodiment, the probe is equipped with an illumination optical path.

[0011] In one embodiment, the combination of the probe tip electrically connected to the control system includes a medical endoscope camera system.

[0012] In one embodiment, the transport assembly includes a circulatory transporter for circulatory transport of a lumen instrument and a clamp disposed on the circulatory transporter for carrying the lumen instrument.

[0013] In one embodiment, the circulating conveyor includes a conveyor belt with a chain disposed on the inner side of the conveyor belt. The chain meshes with a sprocket, and the shaft hole of the sprocket is connected to the output shaft of the drive component.

[0014] In one embodiment, the clamp is a flexible pipe clamp.

[0015] In one embodiment, the drive source is an electric actuator.

[0016] In one embodiment, there are a plurality of clamps, and the plurality of clamps are arranged in a circumferential array on the upper surface of the conveyor belt.

[0017] In one embodiment, the resilient clamp is integrally formed as an open annular structure.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. This application achieves automation and high efficiency in detecting contaminants inside tubular instruments by combining a detection component with a transmission component. Specifically, the transmission component circulates and the clamps carry and position the instrument, keeping it coaxial with the carrier tube of the detection component. The carrier tube, moving linearly and reciprocatingly, then precisely delivers the detection tip into the lumen. This design only requires medical personnel to continuously place or remove tubular instruments from the clamps, eliminating the need to simultaneously hold the instrument and the detection component. This avoids the inefficiency and positioning errors of traditional manual detection, significantly improving the speed, consistency, and reliability of pre-detection, and providing a foundation for large-scale, batch pre-detection.

[0019] 2. This application adopts an open elastic tube clamp, which makes the elastic tube clamp adaptive and easy to operate. The elastic structure can clamp tube instruments of different diameters, and has good versatility and inclusiveness. At the same time, the open design makes it very convenient and quick to put in and take out instruments, further improving the automation and efficiency of the entire testing process.

[0020] 3. For tubular instruments with larger needle diameters, this application enables automated feeding of tubular instruments by setting the elastic clamp as an open semi-circular ring structure. In other words, only medical personnel need to perform the feeding action, which further improves the testing efficiency.

[0021] 4. This application relies on the step of the lumen instrument itself, so that the step abuts against the side of the elastic clamp each time it is placed, which can ensure the consistency of the position of the lumen instrument on the elastic clamp and ensure that subsequent testing can be carried out normally.

[0022] 5. This application arranges multiple fixtures in a circumferential array on the conveyor belt, making the most of the space on the conveyor belt. This allows for more workstations to be arranged on the belt per unit length or area, thereby greatly improving the space utilization of the equipment and the number of instruments that can be tested in a single run. This achieves high-throughput testing and is suitable for sterilization supply centers or hospitals that need to process a large number of instruments.

[0023] 6. This application uses a drive source to precisely control the linear reciprocating motion of the carrier tube, which ensures that the probe tip enters and exits the cavity at a constant speed and with accurate stroke, thus guaranteeing the stability and repeatability of the detection process, eliminating the uncertainty of manual operation, and providing a foundation for connecting with the upper control system to achieve fully automatic operation.

[0024] 7. This application specifies the drive source as an electric linear actuator, which can directly convert the rotational motion of the motor into precise linear motion without the need for complex pneumatic pipelines or hydraulic systems. It has a fast response speed, high position control accuracy, low noise, and is clean and pollution-free, meeting the high requirements of medical equipment for precision, environment and reliability.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1-2As shown, a device for detecting and identifying contaminants inside a tubular instrument mainly includes a detection component for detecting whether contaminants exist inside the lumen of a tubular instrument a, and a transmission component for carrying and transporting the tubular instrument a. Both the detection component and the transmission component are installed on a workbench in a medical room or testing room during installation and use.

[0030] The device is used as follows, and the process of detecting contaminants inside the tubular instruments is as follows: When the transmission component moves the tubular instrument a to be tested to the designated position (i.e., the testing position), the transmission component stops moving. At this time, the probe end 1 of the probe component moves along a predetermined path and extends into the lumen of the tubular instrument a to detect whether there is contaminant inside the instrument's lumen. After the detection is completed, the probe end 1 resets and moves out of the lumen. Then, the transmission component continues to move, not only moving the tested tubular instrument a to the next station, but also moving another new tubular instrument a to be tested to the designated testing position.

[0031] The specific structures of the detection component and transmission component proposed in this embodiment are described in further detail below.

[0032] Detection components: The detection assembly includes a carrier tube 2 and a control system 9. The carrier tube 2 is connected to the output end of the drive source 3 via a connector, so that when the drive source 3 starts operating, the carrier tube 2 is driven to perform linear motion. Figure 1 As shown, Figure 1 The range indicated by the length of the dashed box represents the range of the horizontal movement path of the carrier tube 2. This range of movement path can be controlled by setting the stroke size when the drive source 3 drives the carrier tube 2 to move.

[0033] In one embodiment, the drive source 3 can be an electric actuator. In this case, one end of the connector is located at the extended end (i.e., the output end) of the electric actuator, and the other end is used to fix the carrier tube 2. Preferably, when the electric actuator is placed on the worktable, the extended end of the electric actuator is located at a certain distance from the worktable surface, thereby ensuring that the carrier tube 2 is suspended and does not contact the worktable.

[0034] A detection end 1 is provided at one end of the carrier tube 2 near the transmission component. The detection end 1 is electrically connected to the control system 9. The control system 9 is also electrically connected to the traceability system 4 and the audible and visual alarm 5. Wherein: The probe 1 is used to capture an image of whether there is dirt inside the tubular instrument a, and uses an image sensor to convert the optical signal into an electrical signal.

[0035] The control system 9 can be used to process the electrical signals transmitted by sensors, such as noise reduction, white balance, color calibration, amplification enhancement, etc., and supports functions such as image freezing, video recording, and parameter adjustment (such as brightness, contrast). The control system 9 also incorporates a dedicated image processor (such as an FPGA chip) to achieve ultra-high-definition image output. Meanwhile, the control system 9 is equipped with a medical-specific high-definition display (brightness ≥ 1000 cd / ㎡, anti-glare), supporting multi-screen linkage (such as the main surgical field screen + parameter monitoring screen); furthermore, the control system 9 is equipped with a storage module to save the collected images in real time.

[0036] In one embodiment, when designing the above-mentioned detection head 1, it includes a micro camera (usually a CMOS sensor) and a light guide fiber bundle. The diameter of the detection head 1 needs to meet certain size requirements to ensure that it can be smoothly inserted into the lumen medical devices to be tested (such as laparoscopic instruments, hysteroscopic instruments, dental handpiece pipelines, respiratory pipelines, etc.). When detecting lumen medical devices of different models and sizes, the diameter of the detection head 1 only needs to meet the detection requirements of the smallest model / size lumen medical device.

[0037] In a preferred embodiment, the detection head 1 is further equipped with an illumination optical path, which is used to evenly project the light source to the front end of the micro camera to illuminate the inner wall of the lumen, facilitating the detection head 1 to clearly capture the image inside the lumen.

[0038] During use, the detection head 1 is aligned with the lumen opening of the lumen medical device and inserted into the lumen medical device under the drive of the drive source 3. After the detection head 1 is inserted into the lumen, the illumination optical path is used to provide a light source, enabling the control system 9 to obtain the image inside the lumen with the assistance of the illumination optical path and the detection head 1, and display the image after processing, so that medical staff can directly observe the image inside the lumen, and then judge whether there is dirt in the lumen medical device a.

[0039] It should be noted that the detection methods of the inner wall of the lumen by the detection head 1 and the control system 9, the connection relationship between the two, and their own structural compositions are all prior arts, and both the detection head 1 and the control system 9 can be replaced with components in the prior art. For example, the relevant technology has been disclosed in the text with the authorization publication number CN218629578U.

[0040] In a preferred embodiment, the combination of the detection head 1 and the control system 9 can select a medical endoscope camera system. In specific implementation, directly replace the detection head 1 with the endoscope probe of the medical endoscope camera system, that is, use the endoscope probe as the detection head 1.

[0041] When in use, the light emitted by the medical endoscope imaging system travels through the optical fiber beam and the endoscope body to the inside of the tubular instrument (a), illuminating the part of the instrument to be examined. The objective lens images this part onto a CCD array, and the CCD driver circuit controls the CCD to acquire the image and output a standard video signal. Medical personnel can directly determine whether the tubular instrument has passed the inspection by visual inspection (the presence of contaminants indicates a failed inspection, while the absence of contaminants indicates a passed inspection).

[0042] Transmission components: The transmission assembly includes a circulating conveyor 6 and multiple clamps 7 mounted thereon, arranged in a circumferential array on the circulating conveyor 6. When the circulating conveyor 6 is in operation, it drives the multiple clamps 7 to rotate cyclically. The position of the circulating conveyor 6 is opposite to the mounting position of the carrier tube 2 on the worktable, ensuring that when the circulating conveyor 6 stops moving, any set of clamps 7 on it maintains a relative arrangement with the carrier tube 2.

[0043] Preferably, the straight line in which the rotation direction of the circulating conveyor 6 is located is perpendicular to the moving direction of the probe end 1 in the probe assembly. The axis of the tubular instrument a held by the clamp 7 is on the same straight line as the axis of the carrier tube 2 and the axis of the probe end 1, or the distance between the two axes of the tubular instrument a and the probe end 1 is kept within the allowable range, so that the carrier tube 2 and the probe end 1 move along the straight line. Figure 1 When the movement extends in the direction of the middle arrow, it can be inserted into the lumen-type instrument a for testing, but without damaging the lumen-type instrument a.

[0044] In practice, medical staff pre-place the tubular instruments a to be tested sequentially on multiple clamps 7. When the circulating transport component 6 rotates at a certain moment, the relative position of a certain tubular instrument a and the probe end 1 is as follows: Figure 1 As shown, at this time, drive source 3 is working, which drives probe head 1 to the left ( Figure 1 The device moves in the direction indicated by the middle arrow until it enters the lumen of instrument a for testing. The test signal is transmitted to the control system 9, which then judges the signal and feeds back the judgment to the audible and visual alarm 5. When the audible and visual alarm 5 sounds and flashes, it alerts medical staff that there are foreign objects such as dirt in the lumen of the tubular instrument a, indicating that it is unqualified. When the audible and visual alarm 5 does not sound or flash, it indicates that it is qualified. During this testing process, the control system 9 feeds back the judgment result to the traceability system 4 each time, which can be used to trace the source in case of subsequent misjudgments. After the current lumen instrument a is tested, the circulating conveyor 6 continues to rotate, causing the next lumen instrument a on the clamp 7 to move to the testing position for testing. This process is repeated until all lumen instruments have been tested.

[0045] Furthermore, it can be electrically connected to the control system 9, such as the terminal 8, so that medical staff can know the current inspection status of the tubular instrument a at any time. This embodiment does not specifically limit the terminal 8; for example, the terminal 4 can be a commonly used mobile phone, tablet, or laptop computer.

[0046] In one embodiment, such as Figure 2 As shown, the aforementioned circulating conveyor 6 includes a conveyor belt 601, with a chain disposed on the inner side of the conveyor belt 601. The chain meshes with a sprocket, and the shaft hole of the sprocket is connected to the output shaft of a drive component (such as a motor). When the motor rotates, the motor drives the sprocket to rotate, which in turn drives the chain and the conveyor belt 601 disposed on it to perform a circulating conveying action. The elastic tube clamp (i.e., the aforementioned clamp 7) disposed on the conveyor belt 601 clamps the tubular instrument and moves together in a circulating motion. Figure 2 The diagram shows a case where six sets of clamps 7 are installed on the conveyor belt 601. In actual use, it is not limited to six sets. The number of clamps 7 can be set according to the space of the medical room or testing room and the layout of the workbench.

[0047] It should be noted that when the output shaft of the motor is connected to the shaft hole of the sprocket, the output shaft of the motor should be able to lift the entire transmission assembly, thereby maintaining a certain distance from the surface of the workbench in the medical room or testing room, so as to ensure that the transmission assembly can realize all processes of loading, conveying and unloading of tubular instruments a.

[0048] Preferably, the inner diameter and type of the elastic tube clamp can be selected according to the type a of the tubular instrument to be tested.

[0049] When using the aforementioned device for detecting and identifying contaminants inside tubular instruments, medical personnel can first push the tubular instrument (a) from top to bottom or horizontally into the elastic clamp, relying on the clamping action of the elastic clamp to limit and fix the tubular instrument (a). Figure 2 From the state shown, the definition Figure 2With the left side designated for insertion and the right side for removal, and the detection position set in the middle, a medical worker can stand on each side of the device during the detection process. The medical worker on the left sequentially places the lumen-type instrument (a) to be tested onto multiple elastic clamps, while the medical worker on the right removes the lumen-type instrument (a) detected by the probe end 1 from the elastic clamps, achieving efficient detection. The placement and removal of the lumen-type instrument (a) can be performed simultaneously with the detection end 1 detecting the lumen-type instrument (a) in the middle position. During this time, the conveyor belt 601 is in standby mode, allowing the medical worker to place or remove the stationary lumen-type instrument (a). With practice, or when time permits for placing and removing the instrument (a), the operation can be completed by one person.

[0050] It should be noted that when setting the non-running state time of the motor in the transmission component, the start and stop of the motor are controlled by a time relay and a contactor. Specifically, the running and stopping cycles are adjusted by the knob of the time relay. The core logic is to use the time relay to cycle through the "on / off" state, thereby controlling the contactor to engage and disengage, realizing the periodic start and stop of the motor. During the stop time, the loading, unloading, and inspection of tubular instruments (a) can be carried out simultaneously.

[0051] Furthermore, the placement of the lumen-type instrument a on the elastic clamp can be determined by the experience of medical personnel or standardized based on the characteristics of the instrument a itself. Preferably, the lumen-type instrument a has a stepped structure due to its own construction. Therefore, during the horizontal insertion and placement of the instrument a on the elastic clamp, when the step abuts against the elastic clamp, it indicates that the instrument is properly inserted, ensuring that each lumen-type instrument a is in the same position on its respective elastic clamp; or, as... Figure 2 As shown in the diagram, the lumen-type instrument a can also be pushed into the elastic clamp from top to bottom (inward from the opening of the elastic clamp), and then the lumen-type instrument a can be moved back and forth until the step on it abuts against the elastic clamp.

[0052] According to the corresponding type of tubular instrument a, a corresponding clamp 7 is set on the conveyor belt 601, and the probe end 1 is adjusted to the coaxial layout position corresponding to the type of tubular instrument a.

[0053] In one embodiment, different adaptable elastic tube clamps can be provided for lumen instruments a with different diameters. For example, for some small-diameter lumen instruments a, the elastic tube clamp can be set as a notched ring, such as... Figure 2 As shown; for certain large-diameter tubular instruments (a), the elastic clamp can be set as a semi-circle, such as... Figure 3 As shown.

[0054] In one embodiment, several flexible clamps are defined from left to right as a feeding station (b), a testing station (c), and a discharge station (d). During testing, medical personnel simply place the large-diameter tubular instrument (a) on top of the flexible clamp at the feeding station (b). When the large-diameter tubular instrument (a) is transported to the testing station (c), the probe tip 1 is directly inserted coaxially into it for inspection. During this inspection, since the outer diameter of the probe tip 1 is smaller than the inner diameter of the tubular instrument (a), it will not contact the inner wall of the tubular instrument (a). After the inspection is completed, as the flexible clamp moves, it arrives at the discharge station (d), realizing the automatic discharge of the tubular instrument (a).

[0055] In a preferred embodiment, to ensure the stability of the lumen instrument a (especially a large-diameter lumen instrument a) when held by the elastic clamp, for two or more different positions of the lumen instrument a, the front and rear of 601 are adjusted (within a certain range). Figure 3 Taking the perspective as an example, the one closer to the observer's viewpoint is called "money," and the one farther away is called "back." Two or more elastic tube clamps are set one by one to ensure that the tube-type instruments are clamped more securely.

[0056] In addition, a collection box 10 can be installed below the unloading station d to collect the tested tubular instruments a. Generally, since the elastic tube clamp and the probe end 1 are placed on the workbench, the collection box 10 can be placed directly on the ground.

[0057] Of course, in order to ensure the position of the large-diameter lumen instrument a on the elastic clamp, as mentioned above, the large-diameter lumen instrument a can be positioned by contacting the side of the elastic clamp with the step provided on it, so that each large-diameter lumen instrument a can be kept in the same position on the elastic clamp.

[0058] like Figure 4 As shown, in one embodiment, the detection and identification device for contaminants inside a tubular instrument further includes a cleaning device for automatically cleaning the interior of the tubular instrument a. The cleaning device is electrically connected to the control system 9. The cleaning device can be arranged downstream of the detection component so that when the detection component detects contaminants in the tubular instrument a, it can clean the interior of the tubular instrument a. The control system 9 is used to control the cleaning device.

[0059] In one embodiment, the cleaning device includes a steam cleaning nozzle 11, a carrier tube 12, and a drive source 13. The steam cleaning nozzle 11 is fixedly installed at the end of the carrier tube 12, and is connected to external cleaning steam. The carrier tube 12 is installed at the extended end of the drive source 13. The drive source 13 provides power for the extension of the carrier tube 12, and the carrier tube 12 supports the steam cleaning nozzle 11. Further, the drive source 13 can be an electric push rod. The length of the carrier tube 12 is greater than the length of the tubular instrument a, so that the steam cleaning nozzle 11 can perform steam cleaning on the entire internal area of ​​the tubular instrument a.

[0060] In another embodiment, the cleaning device and the detection component are mounted on the same position conversion platform at different heights. The lifting platform is electrically connected to the control system 9. When monitoring the interior of a tubular instrument a is required, the detection component is positioned at the same height as the instrument a. If contamination is found in the instrument a after monitoring, and cleaning is necessary, the position conversion platform is adjusted so that the cleaning device is at the same height as the instrument a for cleaning. After cleaning, the control system 9 controls the position conversion platform to return to its initial position for re-inspection of the instrument a, ensuring its cleanliness.

[0061] Furthermore, the position conversion platform can be a lifting platform or a rotating platform, both of which are existing technologies. Those skilled in the art can configure the specific settings as needed.

[0062] like Figure 5 As shown, in one embodiment, the device for detecting and identifying contaminants inside tubular instruments further includes an automatic feeding device 10 for automatically feeding tubular instruments a. The automatic feeding device 10 enables automatic feeding, making it more convenient to use.

[0063] In one embodiment, the automatic feeding device 10 includes a storage bin 101 and a feeding assembly. One side of the storage bin 101 has a feeding port that gradually increases in size from the inside out to allow the addition of tubular instruments a. The bottom of the storage bin 101 gradually decreases in height near the transmission assembly. A discharge port is located on the side of the storage bin 101 near the transmission assembly, with its height slightly greater than the outer diameter of the tubular instrument a, facilitating its passage. An opening is located in the middle of the bottom of the storage bin 101, and the feeding assembly is positioned within this opening. Specifically, when the detection assembly detects a tubular instrument a, the opening of one of the clamps 7 is placed against the discharge port of the storage bin 101. The feeding assembly controls a tubular instrument a to be inserted into the corresponding clamp 7 under its own weight, thus achieving automatic feeding. After detection, the opening of the next clamp 7 is placed against the discharge port of the storage bin 101, and this process is repeated to achieve automatic feeding.

[0064] In order to facilitate the smooth entry of the tubular instrument a in the storage bin 101 into the clamp 7, the clamp 7 includes a clamp middle part 701, which is semi-circular. An extension edge 702 is provided on one side of the clamp middle part 701, which extends tangentially along the clamp middle part 701. An extension edge 703 is provided on the other side of the clamp middle part 701, which extends outward. The extension edge 702 is used to connect with the bottom of the discharge port of the storage bin 101 to guide the bottom of the tubular instrument a, and the extension edge 703 guides the top of the tubular instrument a so that the tubular instrument a can be smoothly inserted into the clamp 7.

[0065] Furthermore, the feeding assembly includes a feeding wheel 102, which is installed in the bottom opening of the storage bin 101. The storage bin 101 is also equipped with a driving component that drives the feeding wheel 102 to rotate intermittently. The driving component can be a stepper motor. A plurality of levers 103 are arranged in an array around the feeding wheel 102. The levers 103 located on the upper part of the feeding wheel 102 are higher than the bottom of the storage bin 101, so as to lock the tubular instrument a and control the discharge of the tubular instrument a.

[0066] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
