Description

Technical Field

[0001] This invention relates to the field of medical device cleaning and disinfection monitoring technology, and more specifically, to a simulation device and detection method for monitoring the cleaning and disinfection of tubular instruments. Background Technology

[0002] Tubular medical devices typically have long, narrow internal channels. During cleaning and disinfection, the cleaning solution needs to enter the lumen and flow along it to effectively clean the inner wall of the lumen. Therefore, the quality of cleaning and disinfection of tubular devices depends not only on the cleaning effect on their external surfaces but also on the irrigation and cleaning effect on their internal lumens.

[0003] Current methods for monitoring the effectiveness of cleaning and disinfection typically involve placing a test card directly inside a spray cleaning device, ultrasonic cleaning device, or other cleaning and disinfection equipment, and judging the quality of cleaning and disinfection by observing changes in the indicators on the test card. This method can reflect the cleaning effect under spray, immersion, or ultrasonic conditions within the equipment cavity, but the test card is mainly located in the external cleaning environment of the instrument, making it difficult to simulate the confined flow channel environment inside a slender tube.

[0004] Because the detection card is not set in the perfusion path connected to the equipment cavity cleaning interface, the existing detection method is difficult to determine whether the cleaning fluid can effectively enter the cavity and effectively clean the inner wall of the cavity. It is also difficult to evaluate the cleaning and disinfection quality of the cavity instrument's exterior and interior in the same detection process.

[0005] Therefore, how to provide a simulation device that can simultaneously simulate the external cleaning environment and the internal perfusion cleaning environment of tubular instruments, and a detection method based on the simulation device, so as to improve the accuracy of monitoring the cleaning and disinfection quality of tubular instruments, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a simulation device and detection method for monitoring the cleaning and disinfection of tubular instruments, which can simultaneously simulate the external cleaning environment and the internal perfusion cleaning environment of tubular instruments, so as to improve the accuracy of monitoring the quality of cleaning and disinfection of tubular instruments.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A simulation device for monitoring the cleaning and disinfection of tubular instruments, comprising: The support block has a first detection card mounting position on its outer side, which is used to install the first detection card. A carrier tube is disposed in the inner cavity of the carrier block, and the inner cavity of the carrier tube is provided with a second detection card mounting position for mounting a second detection card; The liquid inlet assembly has one end penetrating the support block and communicating with the inner cavity of the support tube, and the other end being used to connect to the tube cleaning connector of the cleaning and disinfection equipment. The simulation device is placed in the cleaning and disinfection equipment so that the first detection card comes into contact with the cleaning liquid in the cleaning and disinfection equipment. The liquid inlet assembly can introduce the cleaning liquid output from the lumen cleaning connector into the carrier tube so that the cleaning liquid flows into the carrier tube and into the second detection card.

[0008] On the other hand, the liquid inlet assembly includes a connector and a connecting tube. The connector is used to connect to the lumen cleaning connector. The first end of the connecting tube communicates with the connector, and the second end passes through the support block and communicates with the inner lumen of the support tube.

[0009] On the other hand, the connecting pipe is a spiral pipe.

[0010] On the other hand, the support tube is inserted into the inner cavity of the support block, and the outer wall of the support tube is transitionally fitted with the inner cavity wall of the support block; the bottom of the inner cavity of the support block is provided with a liquid inlet hole, and the liquid inlet hole is connected to the liquid inlet assembly.

[0011] On the other hand, the carrier tube has a bottom port and a top port, the bottom port is connected to the liquid inlet, and the second detection card mounting position is a limiting groove provided in the inner cavity of the carrier tube, the limiting groove is connected between the bottom port and the top port.

[0012] On the other hand, it also includes a locking member, which is located at one end of the support block away from the liquid inlet assembly and is detachably connected to the support block. The locking member is used to confine the support tube within the inner cavity of the support block and to prevent the second detection card from being dislodged from the top tube opening. The locking member has a head end limiting edge formed at its head end. The head end limiting edge is at least partially set corresponding to the first detection card mounting position and is used to limit the first detection card to prevent the first detection card from coming out of the first detection card mounting position.

[0013] On the other hand, the locking member is provided with a liquid outlet hole, which is connected to the top opening of the carrier tube so that the cleaning fluid entering the carrier tube can be discharged through the liquid outlet hole.

[0014] On the other hand, a limiting baffle is provided on the outer side of the support block, and the first detection card mounting position is a limiting cavity formed between the limiting baffle and the outer side wall of the support block. The limiting cavity is connected to the outside of the support block so that the first detection card can contact the cleaning liquid in the cleaning and disinfection equipment.

[0015] On the other hand, the limiting cavity has an insertion port and an opening, the insertion port for inserting the first detection card, and the opening for exposing at least a portion of the surface of the first detection card to the cleaning solution within the cleaning and disinfection equipment.

[0016] A detection method for monitoring the cleaning and disinfection of tubular instruments, applied to the simulation device for monitoring the cleaning and disinfection of tubular instruments as described in any one of the above claims, the detection method comprising: Install the first detection card in the first detection card mounting position; Install the second detection card in the second detection card mounting position; The simulation device is placed in the cleaning and disinfection equipment, and the liquid inlet assembly is connected to the cleaning connector of the cleaning and disinfection equipment. Run the cleaning and disinfection program of the cleaning and disinfection equipment, so that the first detection card comes into contact with the cleaning liquid in the cleaning and disinfection equipment, and the cleaning liquid output from the lumen cleaning connector enters the carrier tube through the liquid inlet assembly, so as to flow into the second detection card in the carrier tube; The cleaning and disinfection quality of the external cleaning environment of the lumen instrument is determined based on the changes in the first detection card, and the cleaning and disinfection quality of the internal perfusion cleaning environment of the lumen instrument is determined based on the changes in the second detection card.

[0017] This invention provides a simulation device for monitoring the cleaning and disinfection of tubular instruments. A first detection card mounting position is provided on the outer side of a support block, allowing the first detection card to be installed on the outer side of the support block. When the simulation device is placed inside a cleaning and disinfection device, the first detection card can directly contact the cleaning solution within the device, thus simulating an environment similar to that of the external tubular instrument subjected to the cleaning solution within the device. Therefore, changes in the first detection card can reflect the cleaning and disinfection quality of the external tubular instrument when it is subjected to the cleaning solution within the device.

[0018] Meanwhile, since the carrier tube is located within the inner cavity of the carrier block, and the inner cavity of the carrier tube has a second detection card mounting position for installing the second detection card, one end of the liquid inlet assembly penetrates the carrier block and communicates with the inner cavity of the carrier tube, while the other end is used to connect to the lumen cleaning connector of the cleaning and disinfection equipment. Thus, when the cleaning and disinfection equipment is running, the cleaning fluid output from the lumen cleaning connector can enter the carrier tube through the liquid inlet assembly and flow into the second detection card within the carrier tube, thereby simulating the process of the cleaning fluid entering the lumen instrument and flowing along the inside of the lumen. Therefore, changes in the second detection card can reflect the cleaning and disinfection quality of the lumen instrument under the perfusion cleaning conditions.

[0019] Therefore, this invention, through the installation of a first detection card on the outside of the support block and a second detection card in the inner cavity of the support tube, places the first and second detection cards in different cleaning fluid environments. The first detection card reflects the cleaning and disinfection quality of the external cavity of the instrument, while the second detection card reflects the perfusion cleaning and disinfection quality of the internal cavity. Compared to simply placing the detection card directly inside the cleaning and disinfection equipment, this invention can simultaneously simulate the external cleaning environment and the internal perfusion cleaning environment of the instrument during the same cleaning and disinfection process, thereby obtaining separate detection results for the external and internal cleaning and disinfection quality of the instrument, improving the accuracy of monitoring the cleaning and disinfection quality of luminous instruments.

[0020] The detection method for monitoring the cleaning and disinfection of tubular instruments provided by this invention is applied to the aforementioned simulation device. A first detection card is installed at a first detection card mounting position outside the support block, and a second detection card is installed at a second detection card mounting position inside the support tube. Simultaneously, the liquid inlet assembly is connected to the tubular cleaning connector of the cleaning and disinfection equipment. Therefore, during the cleaning and disinfection process, the first detection card can contact the cleaning fluid inside the cleaning and disinfection equipment, and the second detection card can receive the cleaning fluid flow into the support tube via the liquid inlet assembly. Thus, this detection method can determine the external cleaning and disinfection quality of the tubular instrument based on changes in the first detection card, and determine the internal cleaning and disinfection quality of the tubular instrument under perfusion conditions based on changes in the second detection card. This achieves simultaneous detection of the external cleaning environment and the internal perfusion cleaning environment of the tubular instrument, improving the accuracy of monitoring the cleaning and disinfection quality of tubular instruments.

[0033] 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.

[0034] Please refer to Figure 1 , Figure 3 and Figure 4 This embodiment provides a simulation device for monitoring the cleaning and disinfection of tubular instruments, including a support block 3, a support tube 4, and a liquid inlet assembly.

[0035] The support block 3 is used to install the detection card and the support tube 4. A first detection card mounting position 31 is provided on the outer side of the support block 3 for installing the first detection card 6. The outer side of the support block 3 refers to the side of the support block 3 facing the cleaning fluid environment inside the cleaning and disinfection equipment; that is, the position where the first detection card 6 can contact the cleaning fluid inside the equipment after the simulation device is placed inside. The first detection card mounting position 31 can support, limit, or accommodate the first detection card 6, keeping it in the detection position on the outer side of the support block 3 during the cleaning and disinfection process.

[0036] The carrier tube 4 is located within the inner cavity of the carrier block 3, which allows the carrier tube 4 to maintain a stable position relative to the carrier block 3. The inner cavity of the carrier tube 4 is provided with a second detection card mounting position 41 for mounting a second detection card 7. The second detection card mounting position 41 can be a slot, cavity, or other limiting structure capable of accommodating and positioning the second detection card 7, as long as it ensures that the second detection card 7 remains within the cleaning fluid flow path within the carrier tube 4. Thus, the second detection card 7 can be positioned inside the carrier tube 4 and maintained within the cleaning fluid flow path. When the inlet assembly is connected to the cleaning and disinfection equipment, the cleaning fluid entering the carrier tube 4 can flow into the second detection card 7, thereby simulating the state of the internal channel of the tubular instrument being cleaned by the cleaning fluid during the cleaning and disinfection process.

[0037] One end of the liquid inlet assembly passes through the support block 3 and communicates with the inner cavity of the support tube 4, while the other end is used to connect to the tube cleaning connector of the cleaning and disinfection equipment. Thus, the cleaning fluid output from the tube cleaning connector can enter the interior of the support tube 4 through the liquid inlet assembly and flow along the interior of the support tube 4 to the second detection card 7.

[0038] In use, the first detection card 6 is installed in the first detection card mounting position 31, and the second detection card 7 is installed in the second detection card mounting position 41. Then, the entire simulation device is placed in the cleaning and disinfection equipment, and the liquid inlet assembly is connected to the cleaning connector of the cleaning and disinfection equipment. After the cleaning and disinfection equipment is running, the cleaning fluid inside the equipment can contact the first detection card 6 located outside the support block 3. At the same time, the cleaning fluid output from the cleaning connector enters the support tube 4 through the liquid inlet assembly and flows into the second detection card 7 within the support tube 4.

[0039] With the above structure, the first detection card 6 is located outside the support block 3. After the simulation device is placed in the cleaning and disinfection equipment, the first detection card 6 can come into contact with the cleaning fluid inside the cleaning and disinfection equipment, thereby simulating the external cleaning environment of the lumen instrument. Changes in the first detection card 6 can be used to reflect the cleaning and disinfection quality of the external lumen instrument. The second detection card 7 is set inside the support tube 4. The cleaning fluid can enter the support tube 4 through the inlet assembly and flow into the second detection card 7, thereby simulating the internal perfusion cleaning environment of the lumen instrument. Changes in the second detection card 7 can be used to reflect the cleaning and disinfection quality under the internal perfusion conditions of the lumen instrument.

[0040] Therefore, this simulation device, through the first detection card mounting position 31 on the outside of the support block 3 and the second detection card mounting position 41 inside the support tube 4, arranges the first detection card 6 and the second detection card 7 at different cleaning fluid application locations. The first detection card 6 reflects the cleaning and disinfection quality of the external environment of the lumen instrument, while the second detection card 7 reflects the cleaning and disinfection quality under the perfusion conditions inside the lumen instrument. Compared to simply placing the detection card directly inside the cleaning and disinfection equipment, this simulation device can simultaneously simulate both the external cleaning environment and the internal perfusion cleaning environment of the lumen instrument during the same cleaning and disinfection process, thereby improving the accuracy of monitoring the cleaning and disinfection quality of lumen instruments.

[0041] Considering that the liquid inlet assembly needs to reliably connect to the cleaning connector of the cleaning and disinfection equipment's tubing on the one hand, and stably introduce the cleaning fluid output from the tubing cleaning connector into the carrier pipe 4 on the other hand, this embodiment further configures the specific structure of the liquid inlet assembly. In one specific embodiment, such as Figure 1 , Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, the liquid inlet assembly includes a connector 1 and a connecting pipe 2. The connector 1 is used to connect to the lumen cleaning connector of the cleaning and disinfection equipment. The connector 1 can be a connection structure suitable for plugging, sleeve-connecting or screwing into the lumen cleaning connector of the cleaning and disinfection equipment, as long as it can achieve communication with the lumen cleaning connector of the cleaning and disinfection equipment.

[0042] The connecting pipe 2 has a first end 21 and a second end 22. The first end 21 communicates with the connector 1, allowing the cleaning fluid to enter the connecting pipe 2 from the connector 1. The second end 22 penetrates the support block 3 and communicates with the inner cavity of the support pipe 4. That is, the connecting pipe 2 at least partially passes through the wall of the support block 3 or extends into the interior of the support block 3, enabling the connecting pipe 2 to form a fluid-passing connection with the support pipe 4 located within the support block 3. Thus, the cleaning fluid output from the cleaning connector of the cleaning and disinfection equipment can sequentially pass through the connector 1 and the connecting pipe 2 into the support pipe 4.

[0043] By setting the liquid inlet assembly as connector 1 and connecting tube 2, connector 1 can be connected to the cleaning and disinfection equipment, and the cleaning fluid can be introduced into the carrier tube 4 through the connecting tube 2, so that the second detection card 7 can receive the cleaning fluid flow, thereby better simulating the flow cleaning state of the internal channel of the lumen instrument and improving the accuracy of monitoring the cleaning and disinfection quality of the internal lumen instrument.

[0044] Considering that the connecting pipe 2 needs to form a cleaning fluid flow path between the connector 1 and the carrier pipe 4, and to minimize the overall space occupied by the simulation device, this embodiment further designs the structure of the connecting pipe 2. In one specific embodiment, such as Figure 1 , Figure 3 , Figure 4 and Figure 8 As shown, the connecting pipe 2 is a spiral pipe. The first end 21 of the connecting pipe 2 is connected to the connector 1, and the second end 22 of the connecting pipe 2 passes through the support block 3 and is connected to the inner cavity of the support pipe 4. The cleaning fluid output from the cleaning connector of the cleaning and disinfection equipment can enter the connecting pipe 2 through the connector 1 and then enter the support pipe 4 along the connecting pipe 2.

[0045] By setting the connecting tube 2 as a spiral tube, the flow path of the cleaning fluid can be extended within a limited space, making the overall structure of the simulation device more compact and more closely resembling the flow state of the cleaning fluid inside the slender lumen instrument. Thus, after the cleaning fluid enters the carrier tube 4 through the connecting tube 2, it flows into the second detection card 7, which is beneficial for reflecting the cleaning and disinfection quality under the perfusion conditions inside the lumen instrument through the second detection card 7.

[0046] Considering that the carrier pipe 4 needs to be stably installed inside the carrier block 3, and that the cleaning fluid introduced by the liquid inlet assembly needs to smoothly enter the carrier pipe 4, this embodiment further configures the installation and liquid inlet structure between the carrier pipe 4 and the carrier block 3. In one specific embodiment, such as Figure 4 , Figure 6 and Figure 7 As shown, the inner cavity of the support block 3 is formed by machining, and the outer wall of the support tube 4 is formed by machining. The dimensions of the inner cavity wall of the support block 3 and the outer wall of the support tube 4 are adapted to each other so that after the support tube 4 is inserted into the inner cavity of the support block 3, the outer wall of the support tube 4 and the inner cavity wall of the support block 3 form a transition fit. Thus, the support tube 4 can be stably held in the support block 3 and is easy to assemble.

[0047] The bottom of the inner cavity of the support block 3 is provided with a liquid inlet hole 32, which communicates with the liquid inlet assembly. Specifically, the second end 22 of the connecting pipe 2 can be fixed to the liquid inlet hole 32 of the support block 3 by means of welding, insertion, threaded connection or sealing connection, so as to form a stable liquid connection between the connecting pipe 2 and the support block 3. After the cleaning fluid enters the connecting pipe 2 through the connector 1, it enters the liquid inlet hole 32 through the second end 22 of the connecting pipe 2, and then enters the support pipe 4 through the liquid inlet hole 32.

[0048] With the above settings, the carrier tube 4 can be stably installed inside the carrier block 3, and the liquid inlet hole 32 can connect the liquid inlet component and the inner cavity of the carrier tube 4, ensuring that the cleaning fluid enters the carrier tube 4 according to the predetermined path, which is conducive to forming a stable internal irrigation detection environment.

[0049] Furthermore, such as Figure 4 and Figure 7 As shown, the carrier tube 4 has a bottom port 42 and a top port 43, with the bottom port 42 communicating with the inlet hole 32. The second detection card mounting position 41 is a limiting groove provided in the inner cavity of the carrier tube 4, connecting the bottom port 42 and the top port 43. Specifically, the limiting groove is a groove-shaped limiting structure formed in the inner cavity of the carrier tube 4, capable of accommodating the second detection card 7 and restricting its movement relative to the carrier tube 4. It should be noted that the shape of the limiting groove is adapted to at least a portion of the outer shape of the second detection card 7 so that the second detection card 7 can be stably maintained in the perfusion path within the carrier tube 4.

[0050] Therefore, after the cleaning fluid enters the carrier tube 4 through the inlet 32, it can enter the area where the limiting groove is located through the bottom port 42, and flow along the limiting groove to the top port 43, so that the second detection card 7 installed in the second detection card mounting position 41 can receive the cleaning fluid. This can better simulate the state of the cleaning fluid entering the cavity of the instrument and flowing along the internal channel, and improve the accuracy of the second detection card 7 in reflecting the quality of the internal cleaning and disinfection of the instrument.

[0051] Considering that the carrier tube 4 and the second detection card 7 need to remain stable during the cleaning fluid filling process, this embodiment also includes a locking component 5. For example... Figures 3 to 5 As shown, the locking member 5 is located at the end of the support block 3 away from the liquid inlet assembly and is detachably connected to the support block 3.

[0052] Specifically, the end of the support block 3 furthest from the liquid inlet assembly is provided with a connecting boss 36. The connecting boss 36 is a boss structure with a through hole, and the through hole of the connecting boss 36 communicates with the inner cavity of the support block 3, so that the top port 43 of the support tube 4 can correspond to the locking member 5 through the through hole of the connecting boss 36. In a specific embodiment, the locking member 5 includes a head end 52 and a connecting cylindrical portion 53 integrally connected to the head end 52. The radially outer side of the head end 52 forms a head end limiting outer edge 521, and the connecting cylindrical portion 53 is sleeved on the connecting boss 36. The outer peripheral wall of the connecting boss 36 is provided with an external thread, and the inner wall of the connecting cylindrical portion 53 is provided with an internal thread that mates with the external thread, so that the locking member 5 is threadedly connected to the connecting boss 36, realizing a detachable connection between the locking member 5 and the support block 3.

[0053] Furthermore, the head end limiting outer edge 521 is at least partially set corresponding to the first detection card mounting position 31, and is used to limit the first detection card 6 to prevent the first detection card 6 from being dislodged from the first detection card mounting position 31.

[0054] Therefore, after the locking member 5 is installed, it can confine the carrier tube 4 in the inner cavity of the carrier block 3 and prevent the second detection card 7 from coming out of the top tube opening 43. At the same time, the outer edge 521 of the head end of the locking member 5 restricts the first detection card 6 from coming out of the first detection card mounting position 31, thereby preventing the carrier tube 4 from loosening or the second detection card 7 from coming out during the cleaning fluid filling process, thereby improving the stability and reliability of the detection process.

[0055] Furthermore, such as Figure 4 and Figure 5 As shown, the locking member 5 is provided with a liquid outlet 51, which is connected to the top opening 43 of the carrying tube 4. Specifically, the liquid outlet 51 penetrates the head end 52 of the locking member 5 and is located in the corresponding axial region of the connecting cylinder 53; the top opening 43 of the carrying tube 4 is connected to the liquid outlet 51 through the through hole of the connecting boss 36 and the inner cavity of the connecting cylinder 53, so that the cleaning fluid entering the carrying tube 4 can be discharged sequentially through the top opening 43, the through hole of the connecting boss 36, the inner cavity of the connecting cylinder 53 and the liquid outlet 51, thereby avoiding the accumulation of liquid in the carrying tube 4 from affecting the flow of the cleaning fluid, and also facilitating the second detection card 7 to fully receive the irrigation cleaning fluid, thereby improving the stability of the monitoring of the quality of irrigation cleaning and disinfection inside the tube cavity.

[0056] Considering that the first detection card 6 needs to be installed on the outside of the support block 3 and can fully contact the cleaning liquid in the cleaning and disinfection equipment during the cleaning and disinfection process, this embodiment further sets the specific structure of the first detection card installation position 31.

[0057] In one specific embodiment, such as Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, a limiting baffle 33 is provided on the outer side of the support block 3. The limiting baffle 33 can be set on the support block 3 by welding, riveting, fastener connection, or integral molding. A limiting cavity is formed between the limiting baffle 33 and the outer wall of the support block 3. The limiting cavity can serve as the first detection card mounting position 31 to accommodate and restrict the position of the first detection card 6. The limiting cavity communicates with the outside of the support block 3, allowing the first detection card 6 installed in the first detection card mounting position 31 to contact the cleaning liquid in the cleaning and disinfection equipment.

[0058] Therefore, the limiting baffle 33 can both block or limit the first detection card 6, keeping the first detection card 6 stably outside the bearing block 3, preventing the first detection card 6 from coming off the first detection card mounting position 31 or shifting significantly during the cleaning fluid flushing process, and ensure that the first detection card 6 contacts the cleaning fluid in the cleaning and disinfection equipment, so as to facilitate the reflection of the cleaning and disinfection quality of the lumen instrument in the external cleaning environment through the first detection card 6.

[0059] Furthermore, such as Figure 1 , Figure 3 and Figure 6 As shown, the first detection card mounting position 31 has an insertion port 34 and an opening 35. The insertion port 34 is used for inserting the first detection card 6 into the first detection card mounting position 31 to facilitate the insertion and removal of the first detection card 6; the opening 35 is used to expose at least a portion of the surface of the first detection card 6 to the cleaning solution in the cleaning and disinfection equipment, so as to prevent the first detection card 6 from being completely blocked by the limiting baffle 33, and to allow the first detection card 6 to fully contact the cleaning solution.

[0060] In one specific embodiment, there is a gap between the limiting baffle 33 and the outer wall of the support block 3, and an insertion port 34 is formed between the top of the limiting baffle 33 and the outer wall of the support block 3, through which the first detection card 6 can be inserted into the limiting cavity. The limiting baffle 33 has an opening 35 on the plate wall facing the support block 3. After the first detection card 6 is installed in the first detection card mounting position 31, at least a part of the surface of the first detection card 6 can be exposed to the cleaning liquid in the cleaning and disinfection equipment through the opening 35, ensuring the responsiveness of the first detection card 6 to the action of the cleaning liquid in the cleaning and disinfection equipment, thereby improving the reliability of monitoring the external cleaning and disinfection quality of the tubular instruments.

[0061] Furthermore, after the locking member 5 is installed on the support block 3, the head end limiting outer edge 521 is located on the side of the insertion port 34 facing away from the limiting cavity. That is to say, the head end limiting outer edge 521 at least partially corresponds to the insertion port 34 and can block the part of the first detection card 6 that extends out of the insertion port 34, so as to restrict the first detection card 6 from being dislodged from the first detection card mounting position 31 through the insertion port 34, thereby further improving the installation stability of the first detection card 6 during the cleaning fluid flushing process.

[0062] Considering that the simulation device needs to be placed in cleaning and disinfection equipment and will come into contact with cleaning fluid during the testing process, each component of the simulation device should have good structural stability and corrosion resistance. In one specific embodiment, the connector 1, connecting pipe 2, bearing block 3, and locking element 5 can be made of stainless steel, and the bearing pipe 4 can be made of polytetrafluoroethylene (PTFE). Thus, the connector 1, connecting pipe 2, bearing block 3, and locking element 5 can maintain good structural strength and corrosion resistance in the cleaning and disinfection environment, while the bearing pipe 4 can stably accommodate the second test card 7 and supply cleaning fluid, thereby improving the reliability and testing stability of the simulation device.

[0063] Please refer to Figure 10 The present invention also provides a detection method for monitoring the cleaning and disinfection of tubular instruments, which is applied to the simulation device for monitoring the cleaning and disinfection of tubular instruments disclosed in the above embodiments.

[0064] Step S1: Install the first detection card 6 in the first detection card mounting position 31, so that the first detection card 6 is held on the outside of the support block 3 for contact with the cleaning solution in the cleaning and disinfection equipment.

[0065] Step S2: Install the second detection card 7 in the second detection card mounting position 41, so that the second detection card 7 is held in the irrigation path within the carrier tube 4.

[0066] Step S3: Place the simulation device in the cleaning and disinfection equipment and connect the liquid inlet assembly to the lumen cleaning connector of the cleaning and disinfection equipment. The lumen cleaning connector is the interface in the cleaning and disinfection equipment used to deliver cleaning fluid into the lumen of the instrument. After the liquid inlet assembly is connected to the lumen cleaning connector, the cleaning fluid output from the lumen cleaning connector can enter the carrier tube 4 through the liquid inlet assembly.

[0067] Step S4: Run the cleaning and disinfection program of the cleaning and disinfection equipment, so that the first detection card 6 comes into contact with the cleaning liquid in the cleaning and disinfection equipment to simulate the environment in which the outside of the lumen instrument is subjected to the action of the cleaning liquid in the cleaning and disinfection equipment; at the same time, the cleaning liquid output from the lumen cleaning connector enters the carrier tube 4 through the liquid inlet component, and flows into the second detection card 7 in the carrier tube 4 to simulate the environment in which the internal channel of the lumen instrument is cleaned by the cleaning liquid.

[0068] Step S5: Determine the cleaning and disinfection quality of the external cleaning environment of the lumen instrument based on the changes in the first detection card 6, and determine the cleaning and disinfection quality of the internal perfusion cleaning environment of the lumen instrument based on the changes in the second detection card 7.

[0069] Using the above-described detection method, the first detection card 6 and the second detection card 7 are positioned at different locations. The first detection card 6 reflects the cleaning and disinfection quality under external cleaning conditions for the lumen instrument, while the second detection card 7 reflects the cleaning and disinfection quality under internal perfusion cleaning conditions for the lumen instrument. Therefore, this detection method can simultaneously obtain the cleaning and disinfection quality detection results for both the external and internal parts of the lumen instrument within the same cleaning and disinfection procedure, improving the accuracy of monitoring the cleaning and disinfection quality of lumen instruments.

[0070] Furthermore, before step S2, the detection method may further include step S21, removing the locking member 5 to open the top port 43 of the carrier tube 4; after step S2, the detection method may further include step S22, connecting the locking member 5 to the carrier block 3 to confine the carrier tube 4 within the inner cavity of the carrier block 3, and restricting the second detection card 7 from dislodging from the top port 43. Simultaneously, the head end limiting outer edge 521 limits the first detection card 6, restricting its dislodging from the first detection card mounting position 31. This improves the installation stability of the second detection card 7 during the irrigation detection process and enhances the installation stability of the first detection card 6 during the cleaning fluid flushing process.

[0071] Furthermore, after step S4, the detection method may also include step S41, disconnecting the connection between the liquid inlet assembly and the lumen cleaning connector, and removing the simulation device from the cleaning and disinfection equipment; after step S41, when performing step S5, the first detection card 6 and the second detection card 7 can be removed respectively and their changes can be observed to evaluate the cleaning and disinfection quality of the lumen instrument under the external cleaning environment and the internal perfusion cleaning environment respectively.
