Description

Technical Field

[0001] This invention relates to the field of medical device disinfection monitoring technology, specifically to a sampling device and method for detecting endoscopic disinfectant based on ultraviolet detection. Background Technology

[0002] Endoscopes, as invasive medical devices, are widely used in clinical diagnosis and treatment in gastroenterology, respiratory medicine, urology, and other fields. Their disinfection effectiveness directly affects patient safety, and the concentration of the disinfectant solution is a key indicator determining the disinfection effect. Currently, clinical disinfection of endoscopes mainly uses glutaraldehyde, peracetic acid, sodium hypochlorite, and quaternary ammonium salts for immersion disinfection. According to the People's Republic of China Health Industry Standard WS507—2016 "Technical Specifications for Cleaning and Disinfection of Flexible Endoscopes," different types of disinfectants must maintain specific concentration ranges to achieve qualified disinfection effects: glutaraldehyde concentration must be ≥2% (alkaline), peracetic acid concentration must be 0.2%~0.35% (volume fraction), and sodium hypochlorite concentration must be controlled between 0.005%~0.045% depending on the disinfection scenario. Too low a concentration will lead to incomplete disinfection and cross-infection; too high a concentration will corrode the endoscopic instruments, shorten their lifespan, and pose occupational exposure hazards to medical personnel.

[0003] The current methods for detecting and controlling the concentration of endoscopic disinfectant mainly rely on manual, timed sampling. Furthermore, traditional single-point detection cannot reflect the spatial concentration distribution, and the sampling depth is generally fixed and inconvenient to adjust. To address these issues, existing equipment needs to be improved. Summary of the Invention

[0020] 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.

[0021] Please see Figures 1-6 The present invention provides a technical solution: a sampling device for detecting endoscopic disinfectant based on ultraviolet detection, comprising a support box 1, a first bracket 4 fixed to the top of the support box 1, a first rotating shaft 3 fixed to the bottom of the first bracket 4, a rotating frame 5 fixed to the bottom of the first rotating shaft 3, an opening 6 on one side of the support box 1, the rotating frame 5 passing through the opening 6, a rubber sleeve 7 uniformly fixed to the outer circumference of the rotating frame 5, a sampling tube 8 inserted into the rubber sleeve 7, a top cover 9 threadedly connected to the top of the sampling tube 8, a second bracket 14 and a sampling mechanism 16 fixed to the top of the support box 1, the sampling mechanism 16 passing through the second bracket 14.

[0022] A second liquid extraction pipe 17 is uniformly fixed on one side of the support box 1. The end of one of the second liquid extraction pipes 17 is engaged with the top of the sampling mechanism 16, and the beginning of the second liquid extraction pipe 17 is connected to the liquid extraction mechanism 18 through a pipe clamp 19.

[0023] In this embodiment, as Figure 2 and Figure 3 As shown, a motor 2 is fixed to the top of the inner side of the support box 1, and the bottom of the motor 2 is connected to the first rotating shaft 3. The first rotating shaft 3 can rotate under the action of the motor 2, thereby driving the corresponding components to rotate.

[0024] In this embodiment, as Figure 2 and Figure 3 As shown, plastic baffles 10 are uniformly fixed on the inner circumference of the top cover 9, and two adjacent plastic baffles 10 are in contact with each other. The plastic baffles 10 can only be bent downwards and not upwards, so the sample in the sampling tube 8 can only enter and not exit.

[0025] In this embodiment, as Figure 2 and Figure 3 As shown, a first bevel gear 11 is fixed to the outer side of the first rotating shaft 3, and a second bevel gear 12 is meshed with one side of the first bevel gear 11. A second rotating shaft 13 is fixed to one side of the second bevel gear 12, and the second rotating shaft 13 is rotatably connected to the first bracket 4 and the second bracket 14. A spur gear 15 is fixed to one end of the second rotating shaft 13. When the first rotating shaft 3 rotates, the spur gear 15 can rotate under the driving action of the first bevel gear 11, the second bevel gear 12 and the second rotating shaft 13.

[0026] In this embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the sampling mechanism 16 includes a liquid pump 1601, and a first liquid extraction pipe 1602 is fixed to the top of the liquid pump 1601. A first liquid outlet pipe 1603 is fixed to one side of the liquid pump 1601. A gear ring 1604 is fixed to the outside of the first liquid outlet pipe 1603, and the gear ring 1604 is meshed with the bottom of the spur gear 15. A second liquid outlet pipe 1605 is fixed to the top of the inner side of the support box 1. The first liquid outlet pipe 1603 passes through the second bracket 14 and is rotatably connected to the beginning of the second liquid outlet pipe 1605. Since the gear ring 1604 is meshed with the spur gear 15, the first liquid outlet pipe 1603 can rotate with the rotation of the spur gear 15, thereby driving the liquid pump 1601 and the first liquid extraction pipe 1602 to rotate, which facilitates the positioning of the first liquid extraction pipe 1602 so that it can be aligned with all the second liquid extraction pipes 17 in sequence for multiple sampling.

[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the top of the liquid pump 1601 is connected to the moving plate 1607 via an electric telescopic column 1606, and a sealing connecting cylinder 1608 is fixed on one side of the moving plate 1607. The first end of the first liquid extraction pipe 1602 is engaged in the sealing connecting cylinder 1608, and the end of one of the second liquid extraction pipes 17 is engaged in the sealing connecting cylinder 1608. Before rotating the liquid pump 1601 and the first liquid extraction pipe 1602, the moving plate 1607 moves under the contraction action of the electric telescopic column 1606, and the sealing connecting cylinder 1608 moves and moves away from the second liquid extraction pipe 17. After rotating the liquid pump 1601 and aligning the first liquid extraction pipe 1602 with the next second liquid extraction pipe 17, the moving plate 1607 moves again under the extension action of the electric telescopic column 1606, and the sealing connecting cylinder 1608 moves accordingly and connects the first liquid extraction pipe 1602 with the corresponding second liquid extraction pipe 17.

[0028] In this embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a movable column 1609 is fixed to the bottom of the movable plate 1607, and the movable column 1609 passes through the top of the first liquid outlet pipe 1603 and is connected to the first extrusion block 1610. Limiting rings 1614 are fixed to the inner sides of both the first liquid outlet pipe 1603 and the second liquid outlet pipe 1605. A first movable rod 1612 passes through the limiting ring 1614 inside the first liquid outlet pipe 1603. A first movable block 1611 is fixed to one end of the first movable rod 1612. 1611 is wedge-shaped and fitted to one side of the first extrusion block 1610. A second movable rod 1613 passes through the limiting ring 1614 inside the second liquid outlet pipe 1605, and the second movable rod 1613 is rotatably connected to the other end of the first movable rod 1612. One end of the second movable rod 1613 is fixed to the second extrusion block 1615. The bottom of the second liquid outlet pipe 1605 is connected to the movable column 1617 through the spring 1618, and the movable column 1617 passes through the bottom of the second liquid outlet pipe 1605. It is connected to the second movable block 1616, which is wedge-shaped and fitted to one side of the second extrusion block 1615. A tube 1619 is fixed to the bottom of the movable column 1617. The top of the tube 1619 extends into the end of the second liquid outlet pipe 1605, and the tube 1619 and the second liquid outlet pipe 1605 form a telescopic structure. The bottom of the tube 1619 is inserted into the top cover 9 of one of the sampling tubes 8. Before the rotary pump 1601 and the first extraction pipe 1602, the moving plate 1... 607 moves under the contraction of the electric telescopic column 1606, and the moving column 1609 and the first squeezing block 1610 move accordingly. The first squeezing block 1610 squeezes the first movable block 1611, the first movable rod 1612, the second movable rod 1613 and the second squeezing block 1615 to move. The second movable block 1616, the movable column 1617 and the insertion tube 1619 are squeezed and move upward. The insertion tube 1619 leaves the top cover 9, and then the rotatable liquid pump 1601 and the first liquid extraction pipe 1602 are rotated.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 6As shown, the liquid extraction mechanism 18 includes a hose 1801 and a float 1803. The hose 1801 is connected to the first end of the second liquid extraction pipe 17 via a hose clamp 19. Slide rails 1802 are symmetrically fixed on both sides of the hose 1801. Slider blocks 1804 are symmetrically fixed on both sides of one end face of the float 1803. The sliders 1804 are slidably connected to the slide rails 1802 and are fixed to the slide rails 1802 by fasteners 1805. The slide rails 1802 are marked with scales on the outer side. A liquid extraction head 1806 is fixed to the first end of the hose 1801. Before sampling, the float 1803 can be manually moved to adjust the sampling depth. The adjustment operation can be made more precise by observing the scales on the slide rails 1802. The slider 1804 slides on the slide rails 1802. After the adjustment operation is completed, the fasteners 1805 can be tightened to fix the slider 1804, and the float 1803 is fixed.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 6 As shown, the outer side of the suction head 1806 is fixed to the filter frame 1807 by bolts 1808, and a weight 1809 is fixed to one side of the filter frame 1807. The distance between the float 1803 and the suction head 1806 is adjusted by moving the float 1803. When the suction head 1806 is placed in the disinfectant, the weight 1809 assists the suction head 1806 to sink, and the float 1803 floats on the liquid surface. During the liquid sampling process, the filter frame 1807 can play a filtering role, and the filter frame 1807 is detachable for easy cleaning.

[0031] According to another aspect of the present invention, a method of using a sampling device for detecting endoscopic disinfectant based on ultraviolet detection is provided, comprising the following steps: S1. There are eight sampling heads 1806 and eight sampling tubes 8. The eight sampling heads 1806 can be placed in different disinfection pools or different positions in the same disinfection pool. Each sampling head 1806 corresponds to one sampling tube 8, which can realize multi-point sampling. S2. Before placing the sampling head 1806 into the disinfection tank, manually move the float 1803 and slide the slider 1804 on the slide rail 1802. After adjusting the position of the float 1803, use the fastener 1805 to tighten and fix the slider 1804. When the sampling head 1806 is placed into the disinfection tank, the float 1803 floats on the liquid surface. The sampling depth can be adjusted by adjusting the position of the float 1803. S3. The liquid pump 1601 operates, the liquid head 1806 draws the disinfectant at the corresponding position, the filter frame 1807 filters the disinfectant, and the disinfectant finally enters the corresponding sampling tube 8. The liquid pump 1601 can rotate to facilitate the positioning of the first liquid drawing pipe 1602. At the same time, the rotating frame 5 rotates to position the sampling tube 8. While aligning the first liquid drawing pipe 1602 with the second liquid drawing pipe 17, the corresponding sampling tube 8 is positioned below the insertion tube 1619. S4. Before the rotary pump 1601, the electric telescopic column 1606 retracts, the sealing connecting cylinder 1608 leaves the second liquid extraction pipe 17, and at the same time the insertion tube 1619 leaves the top cover 9. After completing the positioning operation of the first liquid extraction pipe 1602 and the sampling tube 8, the electric telescopic column 1606 extends again, the sealing connecting cylinder 1608 connects the first liquid extraction pipe 1602 with the corresponding second liquid extraction pipe 17, and the insertion tube 1619 is inserted into the top cover 9 of the corresponding sampling tube 8.

[0032] The working principle of this device is as follows: First, manually move the float 1803, and the slider 1804 slides on the slide rail 1802. After adjusting the distance between the float 1803 and the sampling head 1806, tighten the fastener 1805 to secure the slider 1804. Eight sampling heads 1806 and eight sampling tubes 8 are provided. The eight sampling heads 1806 can be placed in different disinfection tanks or at different positions within the same disinfection tank. When the sampling head 1806 is placed in the disinfection tank, the float 1803 floats on the liquid surface. The placement depth of each sampling head 1806 can be adjusted independently. When the liquid pump 1601 is operating... The suction head 1806 draws disinfectant from the corresponding location, and the filter frame 1807 filters the disinfectant. The disinfectant passes sequentially through the hose 1801, the second suction pipe 17, the first suction pipe 1602, the second outlet pipe 1605, and the insertion tube 1619 into the corresponding sampling tube 8. The pump 1601 is rotatable, making it easy to align the first suction pipe 1602 with all the second suction pipes 17 in sequence. Before rotating the pump 1601, the electric telescopic column 1606 retracts, driving the moving plate 1607, the sealing connecting cylinder 1608, the moving column 1609, and the first squeezing block 1606. 610 moves as a whole, the sealing connecting cylinder 1608 leaves the second liquid extraction pipe 17 and retracts completely onto the first liquid extraction pipe 1602. Simultaneously, the first movable block 1611, the first movable rod 1612, the second movable rod 1613, and the second squeezing block 1615 move under the squeezing action of the first squeezing block 1610. The second movable block 1616, the movable column 1617, and the insertion tube 1619 are squeezed upwards, and the insertion tube 1619 completely leaves the top cover 9. Then, the first rotating shaft 3 rotates, driving the rotating frame 5 to rotate, facilitating the positioning of the next sampling tube 8 below the insertion tube 1619. The circular gear 15 rotates under the drive of the first bevel gear 11, the second bevel gear 12, and the second rotating shaft 13, thereby driving the first liquid outlet pipe 1603, the liquid pump 1601, and the first liquid extraction pipe 1602 to rotate as a whole. This facilitates aligning the first liquid extraction pipe 1602 with the next second liquid extraction pipe 17. Then, the electric telescopic column 1606 extends, and the sealing connecting cylinder 1608 connects the first liquid extraction pipe 1602 with the corresponding second liquid extraction pipe 17. The insertion tube 1619 is inserted into the top cover 9 of the corresponding sampling tube 8. The above operation is then repeated to facilitate multiple samplings in an orderly manner.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

10. A method of using a sampling device for detecting endoscopic disinfectant based on ultraviolet detection, applicable to the sampling device for detecting endoscopic disinfectant based on ultraviolet detection as described in claim 9, characterized in that... Includes the following steps: S1. There are eight sampling heads (1806) and eight sampling tubes (8). The eight sampling heads (1806) can be placed in different disinfection pools or different positions in the same disinfection pool. Each sampling head (1806) corresponds to one sampling tube (8), which can realize multi-point sampling. S2. Before placing the sampling head (1806) into the disinfection tank, manually move the float (1803) and slide the slider (1804) on the slide rail (1802). After adjusting the position of the float (1803), use the fastener (1805) to tighten and fix the slider (1804). When the sampling head (1806) is placed into the disinfection tank, the float (1803) floats on the liquid surface. The sampling depth can be adjusted by adjusting the position of the float (1803). S3. The liquid pump (1601) operates, the liquid head (1806) draws the disinfectant at the corresponding position, the filter frame (1807) filters the disinfectant, and the disinfectant finally enters the corresponding sampling tube (8). The liquid pump (1601) can rotate to facilitate positioning of the first liquid drawing pipe (1602). At the same time, the rotating frame (5) rotates to position the sampling tube (8). While aligning the first liquid drawing pipe (1602) with the second liquid drawing pipe (17), the corresponding sampling tube (8) is positioned below the insertion tube (1619). S4. Before the rotary pump (1601), the electric telescopic column (1606) retracts, the sealing connecting cylinder (1608) leaves the second liquid extraction pipe (17), and at the same time the insertion tube (1619) leaves the top cover (9). After completing the positioning operation of the first liquid extraction pipe (1602) and the sampling tube (8), the electric telescopic column (1606) extends again, the sealing connecting cylinder (1608) connects the first liquid extraction pipe (1602) with the corresponding second liquid extraction pipe (17), and the insertion tube (1619) is inserted into the top cover (9) of the corresponding sampling tube (8).
