Description

Technical Field

[0001] This invention relates to the field of catheter cleaning technology, specifically a catheter care and disinfection device. Background Technology

[0002] Catheters are frequently used in medical treatments. After use, they are treated as medical waste. In addition to the fact that the plastic material of the catheters themselves causes significant environmental pollution when discarded, used catheters, especially those used in medical interventions, may contain blood, cells, and tissues on their surface. This means that the surface of the catheter may carry bacteria and viruses, and direct disposal could lead to the spread of viruses. Therefore, medical catheters need to be disinfected before disposal.

[0003] During the cleaning and disinfection process of medical catheters, the inner and outer walls of the catheter are usually cleaned and disinfected simultaneously. The cleaning solution that comes into contact with the inner wall of the catheter mixes with the cleaning solution that comes into contact with the outer wall of the catheter and is constantly exchanged. This constant exchange and mixing of internal and external pathogens during cleaning causes the inner or outer wall, which originally had less bacterial adhesion, to become contaminated with more bacteria. Furthermore, if the inner wall surface is not thoroughly scraped off during the cleaning process, there will still be residual cells and tissues on the inner wall of the catheter after cleaning. Summary of the Invention

[0004] The technical problem of the present invention is to provide a catheter care and disinfection device, and to separate the inner wall cleaning solution and the outer cleaning solution of the catheter, so as to perform individual cleaning on the inner wall of each catheter, thereby improving the cleaning effect and reducing the mixing of sewage.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a catheter care and disinfection device, comprising a main mounting frame, a lower disinfection shell, and an upper disinfection shell. An inner mounting plate is fixedly installed inside both the lower and upper disinfection shells. Multiple large mounting slots are evenly distributed on the inner mounting plate. Small mounting slots are formed on the inner mounting plate corresponding to the positions between the large mounting slots. A large positioning tube is fixedly installed on each of the large mounting slots, and a small positioning tube is fixedly installed on each of the small mounting slots. A large limiting tube is fixedly installed below each of the large mounting slots, and a small limiting tube is fixedly installed below each of the small mounting slots. A large cleaning ball is disposed inside each of the large and small limiting tubes, and a small cleaning ball is disposed inside each of the small and large limiting tubes. A fixing device is provided at the upper end of both the large and small positioning tubes. The fixing device can fix the catheter tip inside the large and small positioning tubes and can control the connection between the large or small limiting tube and the large and small mounting slots.

[0006] As a further embodiment of the present invention, the fixing device includes a limiting member and a fixing rod. The fixing rod is fixedly installed on the upper surface of the large positioning tube and the small positioning tube, and four sets of fixing rods are provided on each of the large positioning tube and the small positioning tube. A threaded rod is threadedly installed on each fixing rod. A driven gear is slidably installed on one end of the threaded rod. A magnetic block plate is fixedly installed on the end of the threaded rod away from the driven gear. The magnetic block plate is inside the large positioning tube and the small positioning tube. An installation ring is rotatably installed on the outside of the large positioning tube and the small positioning tube. An external tooth is fixedly installed on the upper surface of the installation ring, and the external tooth meshes with the driven gear.

[0007] As a further embodiment of the present invention, the limiting member is fixedly installed on the large limiting tube and the small limiting tube. A side gear is rotatably installed inside each limiting member. An extension rod is fixedly installed on the upper part of the side gear. The extension rod passes through the limiting member and extends to the top of the large positioning tube and the small positioning tube. The upper end of the extension rod is rotatably connected to the lower end of one of the fixed rods. A movable gear is fixedly installed on the upper end of the extension rod. An internal tooth is fixedly installed on the upper surface of the mounting ring. The internal tooth meshes with the movable gear.

[0008] As a further embodiment of the present invention, a gear ring is rotatably installed inside the limiting member, the gear ring meshes with the side gear, an arc-shaped groove is formed on the gear ring, and a driving member is rotatably installed on the upper surface of the gear ring. Multiple positioning rods are fixedly installed inside the limiting member at positions corresponding to the edges of the large limiting tube and the small limiting tube, and each positioning rod is rotatably mounted with a movable partition. One end of the movable partition is rotatably connected to the driving member, and the movable partitions can close together to block the connection between the large limiting tube and the small limiting tube and the large mounting groove and the small mounting groove.

[0009] As a further embodiment of the present invention, a lower guide member is fixedly installed on the lower surface of the lower disinfection shell, and through grooves are provided on both the lower guide member and the lower surface of the lower disinfection shell corresponding to the positions of the large limit tube and the small limit tube, and a water pump is provided inside the lower guide member.

[0010] As a further embodiment of the present invention, a movable mounting bracket is rotatably mounted on the main mounting bracket, and a rotating motor is fixedly mounted at both ends of the movable mounting bracket. A mounting shaft is fixedly mounted at the output end of the rotating motor, and the end of the mounting shaft away from the rotating motor is fixedly connected to the lower disinfection shell. A drive motor is fixedly mounted on the main mounting bracket, and the output end of the drive motor is fixedly connected to the movable mounting bracket.

[0011] As a further embodiment of the present invention, both the lower and upper disinfection shells are fixedly mounted with mounting bases, and the mounting bases on the lower and upper disinfection shells are rotatably connected. Both the lower and upper disinfection shells are semi-circular in shape and can be spliced ​​together.

[0012] As a further embodiment of the present invention, both the large and small positioning tubes are made of magnetic material and their magnetism is opposite to that of the magnetic block plate. A water guide pipe is provided on the upper disinfection shell. Both the large and small cleaning balls are made of stainless steel and their outer layers are wrapped with adsorbent activated carbon.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In this invention, the upper and lower disinfection shells work together, with both ends of the conduit fixed inside the lower and upper shells respectively. External disinfection and cleaning solution is introduced into the device from the upper shell. After merging, the upper and lower shells rotate continuously, allowing the cleaning solution to clean the outside of the conduit. Simultaneously, internal disinfection and cleaning solution enters the large and small positioning tubes from the large and small limiting tubes and then into the conduit. Large and small cleaning balls move continuously within the conduit with the water flow, cleaning the inner wall. During this cleaning process, the external and internal disinfection and cleaning solutions do not mix, preventing bacteria on the inner wall from mixing with external bacteria. The two sets of cleaning solutions are discharged separately, allowing for differentiated purification and reducing the volume of highly polluted wastewater. This simplifies subsequent wastewater purification, reduces water waste, and improves the efficiency of subsequent wastewater treatment. In this invention, each conduit inner wall has corresponding cleaning balls for thorough cleaning, preventing the adhesion of pathological tissues and other debris that are difficult to remove.

[0015] 2. In this invention, the installation ring rotates, driving the magnetic block to move and thus fixing the position of the end of the conduit. At the same time, during the rotation, the internal rotation of the limiting component is also determined, so that the inner cleaning fluid and cleaning ball can enter the (large / small) positioning tube from the (large / small) limiting tube below the inner mounting plate. This avoids the trouble of opening the valve with electric drive, reduces the cost of the device, and ensures that the opening and closing of the limiting plate, which serves as a partition between the large and small cleaning balls, is synchronized with the fixing and detachment of the two ends of the conduit. This ensures that both the large and small cleaning balls can move to the inner wall of the conduit, while preventing the loss of the large and small cleaning balls. Attached Figure Description

Detailed Implementation

[0027] 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.

[0028] Please see Figures 1-8 This invention provides a technical solution: a catheter care and disinfection device, comprising a main mounting frame 1, a lower disinfection shell 5, and an upper disinfection shell 6. An inner mounting plate 8 is fixedly installed inside both the lower and upper disinfection shells 5 and 6. Multiple large mounting slots 22 are evenly distributed on the inner mounting plate 8. Small mounting slots 24 are formed on the inner mounting plate 8 corresponding to the positions between the large mounting slots 22. A large positioning tube 9 is fixedly installed on the large mounting slot 22, and a small positioning tube 10 is fixedly installed on the small mounting slot 24. A large limiting tube 21 is fixedly installed below the large mounting slot 22, and a small limiting tube 26 is fixedly installed below the small mounting slot 24. A large cleaning ball 23 is disposed inside the large limiting tube 21, and a small cleaning ball 25 is disposed inside the small limiting tube 26. A fixing device is provided at the upper end of both the large positioning tube 9 and the small positioning tube 10. The fixing device can fix the catheter end inside the large positioning tube 9 and the small positioning tube 10 and can control the connection between the large limiting tube 21 or the small limiting tube 26 and the large mounting slot 22 and the small mounting slot 24.

[0029] In operation, this invention separates the lower disinfection shell 5 and the upper disinfection shell 6. The tubing to be cleaned and disinfected is taken out. Based on the tubing's length (for longer tubing, rotate the large positioning tube 9 or small positioning tube 10 closer to the center of the inner mounting plate 8) and diameter (for larger diameters, select the large positioning tube 9; for smaller diameters, rotate the small positioning tube 10), a suitable large positioning tube 9 or small positioning tube 10 is selected. One end is placed inside the large positioning tube 9 or small positioning tube 10. Then, the tubing end is fixed to the position of the inner mounting plate 8 using a fixing device. Correspondingly, the upper end of the tubing is fixed to the large positioning tube 9 or small positioning tube 10 at the corresponding position on the upper disinfection shell 6 using a fixing device. This ensures that both ends of the tubing are fixed inside the lower disinfection shell 5 and the upper disinfection shell 6 respectively. Multiple sets of tubing can be cleaned at once. During cleaning, the upper disinfection shell 6 and the lower disinfection shell 6 are combined. The outer disinfection and cleaning solution is introduced into the device from the upper disinfection shell 6. After merging, the upper and lower disinfection shells 6 and 5 rotate continuously, causing the cleaning solution to clean the outside of the conduit. Simultaneously, the inner disinfection and cleaning solution enters the large positioning tube 9 and small positioning tube 10 from the large limit tube 21 and small limit tube 26, and then enters the inside of the conduit. The large cleaning ball 23 and small cleaning ball 25 move continuously inside the conduit with the water flow, thereby cleaning the inner wall of the conduit. During the cleaning process, the outer and inner disinfection and cleaning solutions do not mix, avoiding the mixing of bacteria on the inner wall of the conduit with external bacteria. The two sets of cleaning solutions are discharged separately, allowing for differentiated purification treatment, reducing the volume of highly polluted wastewater, thus simplifying the difficulty of subsequent wastewater purification, reducing water waste, and improving the efficiency of subsequent wastewater treatment. In this invention, each conduit inner wall has a corresponding cleaning ball aligned for corresponding cleaning, making the inner wall of the conduit more thoroughly cleaned and avoiding the problem of pathological tissue and other debris adhering to the inner wall of the conduit and being difficult to clean.

[0030] In this invention, the upper disinfection shell 6 and the lower disinfection shell 5 cooperate to fix both ends of the conduit inside the lower disinfection shell 5 and the upper disinfection shell 6, respectively. External disinfection cleaning solution is introduced into the device from the upper disinfection shell 6. After merging, the upper disinfection shell 6 and the lower disinfection shell 5 rotate continuously, causing the cleaning solution to clean the outside of the conduit. Simultaneously, the internal disinfection cleaning solution enters from the large limit tube 21 and the small limit tube 26 into the large positioning tube 9 and the small positioning tube 10, and then enters the inside of the conduit. The large cleaning ball 23 and the small cleaning ball 25 move continuously inside the conduit with the water flow, thereby cleaning the inner wall of the conduit. During the cleaning process, the external disinfection cleaning solution and the internal disinfection cleaning solution do not mix, preventing bacteria on the inner wall of the conduit from mixing with external bacteria. Furthermore, the two sets of cleaning solutions are discharged separately, allowing for differentiated purification treatment, reducing the volume of highly polluted wastewater, thus simplifying the subsequent wastewater purification process, reducing water waste, and improving the efficiency of subsequent wastewater treatment. In this invention, each set of catheter inner walls has a corresponding cleaning ball aligned for cleaning, making the cleaning of the catheter inner wall more thorough and avoiding the problem of pathological tissue and other debris adhering to the catheter inner wall and being difficult to clean.

[0031] As a further embodiment of the present invention, the fixing device includes a limiting member 27 and a fixing rod 17. The fixing rod 17 is fixedly installed on the upper surface of the large positioning tube 9 and the small positioning tube 10, and each large positioning tube 9 and the small positioning tube 10 is provided with four sets of fixing rods 17. Each fixing rod 17 is threadedly installed with a threaded rod 13. A driven gear 12 is slidably installed at one end of the threaded rod 13. A magnetic block plate 18 is fixedly installed at the end of the threaded rod 13 away from the driven gear 12. The magnetic block plate 18 is inside the large positioning tube 9 and the small positioning tube 10. An installation ring 14 is rotatably installed on the outside of the large positioning tube 9 and the small positioning tube 10. An external tooth 15 is fixedly installed on the upper surface of the installation ring 14. The external tooth 15 meshes with the driven gear 12.

[0032] During operation, one end of the conduit is inserted between the side wall of the large positioning tube 9 or the small positioning tube 10 and the magnetic block plate 18. Then, the mounting ring 14 is rotated. The mounting ring 14 drives the driven gear 12, which meshes with it, to rotate through the external teeth 15. The rotation of the driven gear 12 drives the threaded rod 13 to rotate. The rotation of the threaded rod 13 interacts with the threaded line on the fixed rod 17, thereby causing the threaded rod 13 to drive the magnetic block plate 18 to move towards the side wall of the large positioning tube 9 and the small positioning tube 10. This causes the magnetic block plate 18 to be magnetically attracted to the large positioning tube 9 and the small positioning tube 10, thereby clamping the side wall of the conduit between the magnetic block plate 18 and the side wall of the large positioning tube 9 or the small positioning tube 10. This fixes the end of the conduit to be cleaned to the large positioning tube 9 or the small positioning tube 10. At the same time, the rotation of the mounting ring 14 drives the internal rotation of the limiting member 27, thereby eliminating the obstruction effect of the limiting member 27 between the large limiting tube 21 and the small limiting tube 26 and the large positioning tube 9 and the small positioning tube 10.

[0033] In this invention, the installation ring 14 rotates, driving the magnetic block to move and thus fixing the position of the end of the conduit. At the same time, during the rotation, the internal rotation of the limiting member 27 is also determined, so that the inner cleaning fluid and cleaning ball can enter the (large / small) positioning tube from the (large / small) limiting tube below the inner mounting plate 8. This avoids the trouble of opening the valve with electric drive, reduces the cost of the device, and ensures that the opening and closing of the limiting plate, which serves as a partition between the large cleaning ball 23 and the small cleaning ball 25, is synchronized with the fixing and detachment of the two ends of the conduit. This ensures that both the large cleaning ball 23 and the small cleaning ball 25 can move to the inner wall of the conduit, while preventing the loss of the large cleaning ball 23 and the small cleaning ball 25.

[0034] As a further embodiment of the present invention, the limiting member 27 is fixedly installed on the large limiting tube 21 and the small limiting tube 26. A side gear 31 is rotatably installed inside the limiting member 27. An extension rod 20 is fixedly installed on the upper part of the side gear 31. The extension rod 20 passes through the limiting member 27 and extends to the upper part of the large positioning tube 9 and the small positioning tube 10. The upper end of the extension rod 20 is rotatably connected to the lower end of one of the fixed rods 17. A movable gear 19 is fixedly installed on the upper end of the extension rod 20. An internal tooth 16 is fixedly installed on the upper surface of the mounting ring 14. The internal tooth 16 meshes with the movable gear 19.

[0035] During operation, the installation ring 14 rotates, causing the internal gear 16 to rotate. The rotation of the internal gear 16 drives the meshing movable gear 19 to rotate. The rotation of the movable gear 19 drives the extension rod 20 to rotate. The rotation of the extension rod 20 drives the side gear 31 to rotate. The rotation of the side gear 31 drives the meshing gear ring 29 to rotate. The rotation of the gear ring 29 drives the driving component 32 to rotate. The driving component 32 drives the movable partition 28 away from the large limit tube 21 and the small limit tube 26, opening the barrier between the large limit tube 21 and the small limit tube 26 and the large positioning tube 9 and the small positioning tube 10.

[0036] As a further embodiment of the present invention, a gear ring 29 is rotatably installed inside the limiting member 27. The gear ring 29 meshes with the side gear 31. An arc-shaped groove 30 is provided on the gear ring 29. A driving member 32 is rotatably installed on the upper surface of the gear ring 29. Multiple positioning rods 33 are fixedly installed inside the limiting member 27 at positions corresponding to the edges of the large limiting tube 21 and the small limiting tube 26. Each positioning rod 33 is rotatably mounted with a movable partition 28. One end of the movable partition 28 is rotatably connected to the driving member 32. The movable partition 28 can close together to block the connection between the large limiting tube 21 and the small limiting tube 26 and the large mounting groove 22 and the small mounting groove 24.

[0037] As a further embodiment of the present invention, a lower guide member 4 is fixedly installed on the lower surface of the lower disinfection shell 5. The lower guide member 4 and the lower surface of the lower disinfection shell 5 are provided with through grooves corresponding to the positions of the large limit tube 21 and the small limit tube 26. A water pump is provided inside the lower guide member 4.

[0038] As a further embodiment of the present invention, a movable mounting frame 2 is rotatably mounted on the main mounting frame 1. A rotating motor 3 is fixedly mounted on both ends of the movable mounting frame 2. A mounting shaft 11 is fixedly mounted on the output end of the rotating motor 3. The end of the mounting shaft 11 away from the rotating motor 3 is fixedly connected to the lower disinfection shell 5. A drive motor is fixedly mounted on the main mounting frame 1. The output end of the drive motor is fixedly connected to the movable mounting frame 2.

[0039] During operation, the drive motor drives the movable mounting frame 2 to rotate, and the rotation of the movable mounting frame 2 causes the upper disinfection shell 6 and the lower disinfection shell 5 to rotate together. At the same time, the rotation motor 3 drives the upper disinfection shell 6 and the lower disinfection shell 5 to rotate simultaneously through the mounting shaft 11, so that the outer disinfection cleaning solution comes into full contact with the outer wall of the conduit.

[0040] As a further embodiment of the present invention, mounting bases 7 are fixedly installed on both the lower disinfection shell 5 and the upper disinfection shell 6. The mounting bases 7 on the lower disinfection shell 5 and the upper disinfection shell 6 are rotatably connected. Both the lower disinfection shell 5 and the upper disinfection shell 6 are semi-circular in position and can be spliced ​​together.

[0041] As a further embodiment of the present invention, both the large positioning tube 9 and the small positioning tube 10 are made of magnetic material and their magnetism is opposite to that of the magnetic block plate 18. A water guide pipe is provided on the upper disinfection shell 6. Both the large cleaning ball 23 and the small cleaning ball 25 are made of stainless steel and their outer layers are wrapped with adsorbent activated carbon.
