Description

Technical Field

[0001] This invention relates to the field of peritoneal dialysis equipment and consumables, specifically to an automatic disinfection and connection device and method for peritoneal dialysis connectors. Background Technology

[0002] Currently, peritoneal dialysis is an important renal replacement therapy for kidney disease patients in China. Its principle is to use the peritoneum as a semipermeable membrane, periodically infusing dialysis fluid into the peritoneal cavity, allowing it to remain for a certain period, and then draining it out of the body to remove metabolic waste and excess water. Peritoneal dialysis can be performed at home, preserving residual kidney function, avoiding repeated hospital visits, and is more cost-effective, making it particularly advantageous for people in rural and remote mountainous areas. Compared to hemodialysis, it saves a significant amount of medical resources. However, home operation requires patients to manually connect the peritoneal dialysis fluid connector and the peritoneal dialysis tubing connector. This process is prone to bacterial infection due to improper operation, leading to peritonitis, which is currently a major reason preventing patients from choosing peritoneal dialysis and causing technical failures. To better meet treatment needs and improve the safety and efficiency of dialysis treatment, developing a peritoneal dialysis interface device that can automatically connect, is easy to operate, has strong compatibility, and effectively reduces the risk of infection is particularly important.

[0009] This automatic disinfection and connection device achieves automatic cap pulling, cap rotating, cap removal, docking and separation, as well as disinfection operations through a moving module. Its operation can be standardized under the control circuit board and control program, which standardizes the peritoneal dialysis operation process and avoids the non-standard and inconsistent manual cap removal and docking operations. It reduces human intervention and further reduces the risk of infection, and also avoids device damage caused by non-standard manual operation.

[0010] Furthermore, the device housing is provided with a pull-out storage box located in the cap-pulling area and the cap-spinning area. The storage box is located near the cap-pulling baffle and the cap-spinning baffle, and is used to receive the silicone caps and iodine caps that fall off.

[0011] Furthermore, the pull cap baffle is provided with a plurality of pull hooks, each pull hook including a curved section and a straight section. The curved section connects to the silicone cap pull ring on the double-pipe connector when the cap is pulled, and the straight section passes through the pull cap baffle and is fastened by a nut.

[0012] Furthermore, the cap removal assembly includes a top rod support disposed on one side of the multi-directional moving module, and the top rod support is provided with an iodine cap top rod facing the direction of the cap rotating baffle.

[0013] Furthermore, a mounting base is provided on one side of the rotating cap baffle. The first clamping assembly and the rotating cap assembly are arranged vertically on the mounting base. The first clamping assembly includes a rotatable connecting sleeve disposed on the mounting base. The connecting sleeve is used to connect the short pipe joint. The connecting sleeve is arranged directly opposite the mating hole. One end of the connecting sleeve is provided with a flip-up clamping handle. The clamping handle is used to clamp the short pipe joint.

[0014] Furthermore, the rotating cap assembly includes a short tube rotary motor disposed on one side of the mounting base, the output end of the short tube rotary motor is connected to a drive gear, the drive gear meshes with a driven gear, and the driven gear is mounted on the connecting sleeve.

[0015] Furthermore, the multi-directional moving module is an XY bidirectional moving module, and the iodine cap clamp and the second clamping assembly are spaced apart on the slide of the multi-directional moving module; the second clamping assembly includes a clamping fixed seat, and the clamping fixed seat is provided with a flip-up clamping movable seat. The clamping movable seat and the clamping fixed seat are connected by a locking pin, and a clamping groove for fixing the double pipe joint is provided between the clamping fixed seat and the clamping movable seat.

[0016] It includes an X-axis moving module arranged on the device housing parallel to the rotating cap baffle, a Y-axis moving module above the X-axis moving module, a support plate on the slide of the Y-axis moving module, and the iodine cap clamp and the second clamping assembly arranged side by side at intervals on the support plate.

[0017] Furthermore, the iodine cap clamp includes a clamp seat body, on which a clamp tube body is provided. One end of the clamp tube body facing the cap baffle is provided with an iodine cap connection hole, and the other end of the clamp tube body is provided with an iodine cap push hole with a diameter smaller than the iodine cap connection hole. The iodine cap push hole communicates with the iodine cap connection hole.

[0018] Furthermore, the device housing includes a lower shell and an upper cover, with a cover plate between the lower shell and the upper cover. The lower shell has a device switch and a power interface on its outer periphery. Multiple function buttons are provided on the lower shell at a position offset from the upper cover, and the function buttons are electrically connected to the control circuit board. The ultraviolet disinfection assembly includes multiple ultraviolet disinfection lamps disposed on the pull cap baffle, the twist cap baffle, the cover plate, and the upper cover.

[0019] Secondly, an automated sterilization connection method for peritoneal dialysis connectors is provided, comprising the following steps:

[0020] Before use, turn on the ultraviolet disinfection component to disinfect the inside of the device housing;

[0021] After disinfection, open the top cover of the equipment housing, install the short pipe connector at the first clamping assembly, install the double pipe connector at the second clamping assembly, hang the pull ring of the silicone cap at the end of the double pipe connector on the pull hook, align the iodine cap clamp with the old iodine cap at the end of the short pipe connector, and close the top cover.

[0022] Activate the cap-screwing assembly, which, in conjunction with the movement of the multi-directional moving module, unscrews the old iodine cap from the short pipe joint. Simultaneously, the silicone cap separates from the double pipe joint and falls off. The multi-directional moving module continues to move, moving the iodine cap clamp to the cap-removing assembly. The cap-removing assembly pushes the old iodine cap out of the iodine cap clamp and causes it to fall off.

[0023] The multi-directional moving module works in conjunction with the rotating cap assembly to rotate and connect the double tube connector with the short tube connector. The patient then turns on the switch of the short tube connector to begin dialysis.

[0024] After dialysis, the patient closes the short tube connector switch and inserts a new iodine cap through the cap insertion hole. The multi-directional moving module cooperates with the cap rotating assembly and moves in the opposite direction, causing the double tube connector to disengage from the short tube connector.

[0025] The multi-directional moving module moves to align the new iodine cap on the iodine cap clamp with the short pipe connector, and rotates the new iodine cap and the short pipe connector to connect.

[0026] Open the top cover, remove the short pipe connector and the double pipe connector, and discard the old iodine cap and silicone cap.

[0027] Compared with the prior art, the beneficial effects of this invention are: 1. This automatic disinfection and connection device for peritoneal dialysis connectors improves the docking method of double tubes and short tubes, the method of removing silicone caps, and the method of attaching and detaching iodine caps. It can automatically complete connector docking and separation operations, and can also automatically remove and replace iodine caps, greatly reducing manual operation, lowering the risk of infection caused by human intervention, reducing the occurrence of peritonitis, and improving the safety and standardization of patients' self-use of peritoneal dialysis connector connection devices; 2. This automatic disinfection and connection device is not only simple in structure and compact in appearance, but also capable of achieving… The system automatically separates the patient-end peritoneal dialysis catheter connector and iodine cap, automatically exchanges the position of the iodine cap with the silicone cap of the double connector, and automatically connects the patient-end peritoneal dialysis catheter connector with the silicone cap or iodine cap of the double connector. It also achieves disinfection of the chamber and connectors, allowing patients to use the device at home or in any location, reducing the risk of infection and providing greater convenience (compared to the previous requirement of treatment in disinfected areas), thus ensuring dialysis safety. 3. The cap-pulling area and the cap-removing area roughly divide the interior of the device housing into two interconnected functional areas. Under the action of the multi-directional moving module, the iodine cap clamp and the clamped and fixed double tube connector can move within these two areas to perform corresponding operations; 4. The pull hook can automatically remove the silicone cap from the double tube used for peritoneal dialysis, realizing automated cap removal operation, avoiding the infection risk caused by manual cap removal, and reducing the occurrence of peritonitis; 5. When the multi-directional moving module moves the double tube away from the pull hook, it also cooperates with the cap-spinning assembly to remove the old iodine cap, and the cap removal assembly uses the old iodine cap brought from the iodine cap clamp to remove it; with Simultaneously, the movement of the multi-directional moving module and the rotation of the cap assembly allow the double-pipe connector to align with the short pipe connector, thereby automating the entire operation; 6. After completing the dialysis operation, the iodine cap clamp can also be used to install a new iodine cap. Under the synchronous movement of the cap assembly and the multi-directional moving module, the new iodine cap can be installed on the short pipe connector; 7.

[0044] Example 1

[0045] like Figures 1 to 13As shown, an automatic disinfection and connection device for peritoneal dialysis connectors is provided, including a device housing 1. The device housing 1 has a cap-pulling area and a cap-removing area. The cap-pulling area has a cap-pulling baffle 2 with a pull hook 3. The cap-removing area has a cap-removing baffle 4 and a cap-removing assembly. The cap-removing baffle 4 has a cap-installing hole 5 and a docking hole 6. The cap-installing hole 5 is used to place a new iodine cap. The docking hole 6 has a first clamping assembly for connecting a short tube connector 7. The cap-removing baffle 4 also has a cap-removing assembly near the docking hole 6. The cap-removing assembly is used to loosen the old iodine cap on the short tube connector 7, rotate the short tube connector 7 to connect or disconnect the short tube connector 7 from the double tube connector 11, and screw on a new iodine cap.

[0046] The device housing 1 is provided with a multi-directional moving module 8. The multi-directional moving module 8 is provided with an iodine cap clamp 13 and a second clamping component 10. The second clamping component 10 is used to connect a double pipe connector 11. The multi-directional moving module 8 drives the double pipe connector 11 to move in the cap-pulling area and the cap-spinning area to align with the cap-installing hole and the docking hole, and can be moved to the cap-pulling position.

[0047] The device housing 1 is provided with an ultraviolet disinfection component covering the cap-pulling area and the cap-removing area. The device housing 1 is also provided with a control circuit board 14. The cap-removing component, the multi-directional moving module 8 and the ultraviolet disinfection component are electrically connected to the control circuit board 14 respectively.

[0048] This automated disinfection and connection device for peritoneal dialysis connectors improves the docking methods for double and short tubes, the removal of silicone caps, and the installation and removal of iodine caps. It can automatically complete connector docking and separation operations, and can also automatically remove and replace iodine caps, greatly reducing manual operation, lowering the risk of infection caused by human intervention, reducing the occurrence of peritonitis, and improving the safety and standardization of patients' self-use of peritoneal dialysis connector connection devices.

[0049] This automatic disinfection and connection device is not only simple in structure and compact in appearance, but also enables automatic separation of the patient-end peritoneal dialysis short tube connector 7 and the iodine cap, automatic exchange of the position of the iodine cap and the silicone cap of the double tube connector 11, and automatic connection of the patient-end peritoneal dialysis short tube connector 7 and the silicone cap or iodine cap of the double tube connector 11. It also enables disinfection of the chamber and related connectors, allowing patients to use it at home, reducing the burden and difficulty of treatment for patients, and ensuring the safety of dialysis.

[0050] The cap-pulling area and the cap-removing area roughly divide the interior of the equipment housing 1 into two major functional areas. These two areas are interconnected. Under the action of the multi-directional moving module 8, the iodine cap clamp 13 and the clamped and fixed double pipe connector 11 can move within these two areas to perform corresponding operations.

[0051] The cap-removing baffle 2 allows for the placement of the hook 3, which automatically removes the silicone cap 12 (or rubber cap) from the double-tube peritoneal dialysis tubing. This automated cap removal avoids the infection risk associated with manual cap removal, reduces the incidence of peritonitis, and facilitates subsequent automated connection operations, improving operator convenience. Specifically, the hook 3 engages with the pull ring of the silicone cap 12 at the end of the double-tube connector 11, and the multi-directional moving module 8 moves the double-tube away from the hook, thus detaching the silicone cap.

[0052] The cap-spinning baffle 4 is positioned close to the cap-pulling baffle 2. Simultaneously with the hook 3 removing the silicone cap 12, the iodine cap clamp 13 aligns with the docking hole 6 and connects to the old iodine cap at the end of the short pipe connector 7 located at the docking hole 6. The cap-spinning assembly performs a cap-spinning action to simultaneously remove the silicone cap and the iodine cap. In other words, when the multi-directional moving module 8 moves the double pipe away from the hook 3, it also works in conjunction with the cap-spinning assembly to remove the old iodine cap 25.

[0053] Subsequently, the multi-directional moving module 8 can also move the iodine cap clamp 13 and the double pipe connector 11 on it, so that the iodine cap clamp 13 moves to the corresponding cap-loading hole 5, which is the location of the cap-removing component. The cap-removing component is used to remove the old iodine cap 25 brought from the iodine cap clamp 13. At the same time, the double pipe connector 11 corresponds to the docking hole 6. Under the movement of the multi-directional moving module 8 and the rotation of the cap-spinning component, the double pipe connector 11 can be docked with the short pipe connector 7, thereby realizing the automated operation of the whole process.

[0054] After the dialysis operation is completed, the iodine cap clamp 13 can also be used to install a new iodine cap. The new iodine cap can be placed in the iodine cap clamp 13 through the cap mounting hole 5. The iodine cap clamp 13 then moves to the docking hole 6 and docks the new iodine cap with the short pipe connector 7. Under the synchronous movement of the cap rotating assembly and the multi-directional moving module, the new iodine cap can be installed on the short pipe connector.

[0055] The ultraviolet disinfection component can disinfect all internal components before the equipment is started, especially the cap-pulling and cap-removing areas, to avoid contamination by external pathogens; it can also perform appropriate disinfection operations as needed during or after automated operation.

[0056] This automatic disinfection and connection device achieves automatic cap pulling, cap rotating, cap removal, docking and separation, as well as disinfection operations through a moving module. Its operation can be standardized under the control circuit board and control program, which standardizes the peritoneal dialysis operation process and avoids the non-standard and inconsistent manual cap removal and docking operations. It reduces human intervention and further reduces the risk of infection, and also avoids device damage caused by non-standard manual operation.

[0057] Furthermore, the device housing 1 is provided with a pull-out storage box 18 located in the cap-pulling area and the cap-spinning area. The storage box 18 is located near the cap-pulling baffle 2 and the cap-spinning baffle 4, and is used to receive the silicone caps and iodine caps that fall off.

[0058] The storage box 18 can collect various hats that have fallen off. After the dialysis operation is completed, the storage box can be pulled out and the discarded hats can be poured out for harmless disposal. At the same time, it can also prevent various hats from falling off and causing pollution or being difficult to remove inside the equipment.

[0059] Furthermore, the cap baffle 2 is provided with multiple hooks 3, each hook 3 including a curved section and a straight section. The curved section connects to the silicone cap ring on the double-pipe connector when the cap is pulled, and the straight section passes through the cap baffle 2 and is secured with a nut. Figure 3 As shown, two hooks 3 can be arranged side by side, which facilitates the application of pulling force smoothly and better pulls the silicone cap off the double tube.

[0060] Furthermore, the cap removal assembly includes a top rod support 15 disposed on one side of the multi-directional moving module 8, and the top rod support 15 is provided with an iodine cap top rod 16 facing the cap rotating baffle 4.

[0061] The top rod support 15 is installed inside the equipment housing 1, and its iodine cap top rod 16 preferably corresponds to the cap mounting hole 5, which facilitates the subsequent installation of a new iodine cap after the old iodine cap is ejected from the iodine cap clamp. When the multi-directional moving module 8 moves the iodine cap clamp 13 to the iodine cap top rod 16, the iodine cap clamp 13 moves towards the iodine cap top rod 16, and the iodine cap top rod 16 will eject the iodine cap from the iodine cap clamp 13, completing the cap removal operation.

[0062] Furthermore, in combination Figure 4 ,7 9 and Figure 12 As shown, a mounting base 19 is provided on one side of the rotating cap baffle 4. The first clamping assembly and the rotating cap assembly are arranged vertically on the mounting base 19. The first clamping assembly includes a rotatable connecting sleeve 20 disposed on the mounting base 19. The connecting sleeve 20 is used to connect the short pipe joint 7. The connecting sleeve 20 is arranged directly opposite the docking hole. One end of the connecting sleeve 20 is provided with a flip-up clamping handle 21. The clamping handle 21 is used to clamp the short pipe joint 7.

[0063] The short pipe connector 7 is inserted into the connecting sleeve 20, and the iodine cap at its end can extend from the other end of the connecting sleeve 20 to mate with the iodine cap clamp 13; the clamping handle 21 can press down on the short pipe connector 7 to fix it, so that the short pipe connector 7 can rotate with the connecting sleeve 20.

[0064] Furthermore, the rotating cap assembly includes a short tube rotary motor 22 disposed on one side of the mounting base 19. The output end of the short tube rotary motor 22 is connected to a drive gear 23. The drive gear 23 is meshed with a driven gear 24. The driven gear 24 is mounted on the connecting sleeve 20.

[0065] The short tube rotary motor 22 drives the drive gear 23 to rotate, the drive gear 23 drives the driven gear 24 to rotate, and the driven gear 24 drives the connecting sleeve 20 to rotate, which in turn drives the short tube connector 7 connected to it to rotate. With the axial displacement, the iodine cap at the end of the short tube connector 7 can be unscrewed or screwed on.

[0066] The connecting sleeve 20 is installed in the mounting hole above the mounting base 19. Due to the setting of the rotary bearing, the connecting sleeve 20 can rotate relative to the mounting base 19. The short tube rotary motor 22 is installed on the outside of the mounting base 19, and its output shaft passes through the mounting base 19 and is connected to the drive gear 23 on the inside.

[0067] Furthermore, the multi-directional moving module 8 is an XY bidirectional moving module, and the iodine cap clamp 13 and the second clamping assembly 10 are spaced apart on the slide table of the multi-directional moving module 8; combined with Figure 2 , 3 and Figure 13 As shown, the second clamping assembly 10 includes a clamping fixing seat 1001, on which a flip-up clamping movable seat 1002 is provided. The clamping movable seat 1002 is connected to the clamping fixing seat 1001 by a locking pin 1003. A clamping groove for fixing the double pipe connector 11 is provided between the clamping fixing seat 1001 and the clamping movable seat 1002.

[0068] Specifically, the XY bidirectional moving module includes an X-axis moving module 801 arranged on the device housing 1 parallel to the rotating cap baffle, a Y-axis moving module 802 above the X-axis moving module 801, a support plate 9 on the slide of the Y-axis moving module 802, and the iodine cap clamp 13 and the second clamping assembly 10 arranged side by side at intervals on the support plate 9.

[0069] Both the X-axis moving module 801 and the Y-axis moving module 802 can be commercially available, mature linear moving module products. The X-axis is parallel to the baffle direction, and the Y-axis is perpendicular to the baffle direction, that is, the Y-axis is parallel to the axis of the short pipe joint and the double pipe joint. This arrangement allows the X-axis moving module 801 to drive the Y-axis moving module 802 to move back and forth along the baffle, and the Y-axis moving module 802 can drive the iodine cap clamp 13 and the second clamping assembly 10 on it to move closer and further away from the baffle.

[0070] With the second clamping component 10, the clamping movable seat 1002 can be flipped upwards to open it. The connector of the double tube can be placed on the clamping fixed seat 1001. After adjusting the position, the clamping movable seat 1002 is lowered. The clamping movable seat 1002 and the clamping fixed seat 1001 are joined together to clamp the double tube connector 11. Locking the locking pin 1003 can limit and fix the position. The operation is simple, convenient and easy to use.

[0071] The support plate 9 not only supports the installation of the iodine cap clamp 13 and the second clamping assembly 10, but also extends from the slide table on both sides to space the iodine cap clamp 13 and the second clamping assembly 10 at intervals, maintaining a certain distance between them to facilitate the simultaneous execution of the two actions. Preferably, the distance between the center lines of the clamping parts of the iodine cap clamp 13 and the second clamping assembly 10 is basically the same as the distance between the center lines of the cap mounting hole 5 and the docking hole 6. That is, when the double pipe connector 11 is docked with the short pipe connector 7, the iodine cap clamp 13 corresponds exactly to the cap mounting hole 5; moreover, the distance between the center lines of the clamping parts of the iodine cap clamp 13 and the second clamping assembly 10 is also basically the same as the distance between the center line of the docking hole 6 and the location of the hook 3, so that when the silicone cap of the double pipe connector 11 is connected to the hook 3, the iodine cap clamp 13 corresponds exactly to the docking hole 6.

[0072] Furthermore, in combination Figures 6-8As shown, the iodine cap clamp 13 includes a clamp base body, on which a clamp tube body is provided. One end of the clamp tube body facing the cap baffle 4 is provided with an iodine cap connecting hole 1301, and the other end of the clamp tube body is provided with an iodine cap pushing hole 1302 with a diameter smaller than that of the iodine cap connecting hole 1301. The iodine cap pushing hole 1302 communicates with the iodine cap connecting hole 1301.

[0073] The iodine cap clamp 13 can be connected to the cap end of the iodine cap through its iodine cap connection hole 1301. Since the cap end of the iodine cap has a polygonal structure, a corresponding limiting protrusion is provided in the iodine cap connection hole to prevent the iodine cap from rotating relative to the iodine cap connection hole, which is conducive to unscrewing the iodine cap from or onto the short pipe joint; the iodine cap push hole 1302 provided at the other end allows the iodine cap push rod 16 to pass through, thereby pushing the iodine cap out of the iodine cap connection hole 1301.

[0074] Furthermore, the device housing 1 includes a lower shell 101 (including a bottom plate) and an upper cover 102. An upper cover aluminum plate 103 is provided inside the upper cover 102, which can be used to install the lamp plate. A cover plate 104 is provided between the lower shell 101 and the upper cover 102. A device switch 26 and a power interface 27 are provided on the outer periphery of the lower shell 101. Multiple function buttons 28 are provided on the lower shell 101 at a position offset from the upper cover 102. The function buttons 28 are electrically connected to the control circuit board 14. The ultraviolet disinfection assembly includes multiple ultraviolet disinfection lamps disposed on the pull cap baffle, the twist cap baffle, the cover plate, and the upper cover.

[0075] Combination Figure 5 As shown, the ultraviolet disinfection lamp 17 includes a lamp plate 1701 disposed on these baffles and covers, and the lamp plate 1701 is provided with a plurality of ultraviolet lamp beads 1702. The lamp plate 1701 can be installed on the surface of the plate or inside the plate. In this embodiment, the lamp plate 1701 is installed inside these plates, and lamp holes are provided on the plate corresponding to the ultraviolet lamp beads 1702. Through the lamp holes, the ultraviolet light emitted by the ultraviolet lamp beads can irradiate the items to be disinfected, achieving the purpose of disinfection. When the top cover is closed, these ultraviolet disinfection lamps can cover the entire hooded area and the hood-twisting area, thoroughly disinfecting these two areas.

[0079] Before use, turn on all the ultraviolet disinfection lamps 17 to disinfect the inside of the equipment housing 1.

[0080] Step 2: Pipe installation

[0081] After disinfection, the ultraviolet disinfection lamp 17 can be turned off, the top cover 102 of the equipment housing 1 can be opened, the short pipe connector 7 can be installed at the first clamping assembly, and the double pipe connector 11 can be installed at the second clamping assembly 10. In the initial state, the double pipe connector 11 of the multi-directional moving module corresponds to the hook (e.g., Figure 2 (As shown in the initial position), hook the pull ring of the silicone cap 12 at the end of the double pipe connector 11 onto the pull hook 3, and align the iodine cap clamp 13 with the old iodine cap 25 at the end of the short pipe connector 7. Close the top cover 102; at this time, the ultraviolet disinfection lamp can also be turned on again for disinfection.

[0082] Step 3: Disengage from operation

[0083] Activate the cap-screwing assembly, and in conjunction with the movement of the Y-axis moving module 802, unscrew the old iodine cap from the short pipe connector 7, for example, by unscrewing counterclockwise. At the same time, the silicone cap 12 separates from the double pipe connector 11 and falls off. The X-axis moving module 801 moves laterally, moving the iodine cap clamp 13 to the cap-removing assembly. The Y-axis moving module 802 moves backward, and the iodine cap push rod 16 on the cap-removing assembly pushes the old iodine cap out of the iodine cap clamp 13 and it falls off.

[0084] Step 4: Docking Operation

[0085] The double pipe connector 11 and the short pipe connector 7 have corresponded under the above operation, as follows: Figure 9 and Figure 10 As shown, with the continued movement of the Y-axis moving module 802 and the rotation of the cap assembly, the double tube connector 11 and the short tube connector 7 are rotated together and screwed on, for example, by tightening them clockwise. After the connection is completed, the patient turns on the switch of the short tube connector and begins dialysis.

[0086] Step 5: Separation Operation

[0087] After dialysis, the patient closes the short tube connector switch and inserts a new iodine cap through the cap insertion hole 5. The multi-directional moving module 8 cooperates with the cap rotating assembly and moves in the opposite direction, such as counterclockwise, so that the double tube connector 11 disengages from the short tube connector 7.

[0088] Step 6: Applying a new iodine cap

[0089] like Figure 11As shown, the X-axis moving module 801 moves to align the new iodine cap on the iodine cap clamp 13 with the short pipe connector 7. The Y-axis moving module 802 moves, and the cap rotating assembly rotates to rotate and connect the new iodine cap with the short pipe connector 7, for example, by rotating clockwise.

[0090] Step 7: Tube Removal Operation

[0091] Open the top cover 102 of the device housing 1, loosen the clamping handle 21 of the first clamping assembly and the clamping movable seat 1002 of the second clamping assembly, remove the short pipe connector 7 and the double pipe connector 11, and pull out the storage box 18 to empty the discarded old iodine cap and silicone cap. The operation is complete and the process ends.

[0092] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
