Technical Field

[0001] The invention relates to the technical field of catheter cleaning equipment, and in particular to a hemodialysis catheter cleaning device. Background Art

[0002] After the hemodialysis catheter is used, a small amount of blood will remain in the catheter. After a period of time, the blood will coagulate and form a thrombus. When it is used again, it is easy to cause blood vessel blockage and affect hemodialysis treatment. Therefore, the hemodialysis catheter needs to be cleaned.

[0003] Existing hemodialysis catheter cleaning equipment, such as patent number CN 221335787, discloses a hemodialysis tube inner wall cleaning device, including an outer shell, wherein a cleaning mechanism and a drying mechanism are respectively arranged inside the outer shell; the cleaning mechanism includes two sliding blocks, and the side surfaces of the two sliding blocks that are away from each other are fixedly connected to the inner wall of the outer shell, and the interiors of the two sliding blocks are commonly slidably connected to a support plate, and the upper surface of the support plate is fixedly connected to four support columns, and a collecting plate is arranged inside the outer shell, and the top of each support column is fixedly connected to the bottom surface of the collecting plate, and the upper surface of the collecting plate is fixedly connected to vibration springs arranged at equal distances.

[0004] Although the above cleaning device can realize the cleaning of multiple hemodialysis catheters, since the current hemodialysis catheters have spiral openings, when cleaning the catheters after use, it is impossible to fully rinse the spiral openings and the tube bodies of the hemodialysis catheters. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned shortcomings in the prior art and to propose a hemodialysis catheter cleaning device.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] Design a hemodialysis catheter cleaning device, including a platform, and also

[0008] The cylinder body has a positioning and rotating assembly inside thereof for fixing and rotating the hemodialysis catheter;

[0009] The cleaning component includes a cover body arranged at the top of the cylinder body, a water inlet connected to the center of the cover body, a tube body arranged at the bottom of the cover body and connected to the water inlet, and a brushing part spirally distributed along the outer wall of the tube body. After the positioning and rotating component drives the hemodialysis catheter to rotate, the brushing part cleans the spiral opening of the hemodialysis catheter.

[0010] Furthermore, the brushing part includes central bristles, upper bristles and lower bristles distributed on both sides of the central bristles, guide channels respectively located between the central bristles and the upper bristles and the lower bristles, guide protrusions arranged at intervals on the upper bristles and the lower bristles, and through holes connecting the guide channels and the inside of the tube body.

[0011] Furthermore, the inclination directions of adjacent flow-guiding protrusions are opposite.

[0012] Furthermore, the distance from the guide protrusion on the upper side bristles close to the through hole to the through hole is greater than the distance from the guide protrusion on the lower side bristles close to the through hole to the through hole.

[0013] Furthermore, the guide protrusions on the upper bristles close to the through hole are inclined in a direction away from the through hole, and the guide protrusions on the lower bristles close to the through hole are inclined in a direction close to the through hole.

[0014] Furthermore, the positioning rotation assembly includes a clamping portion, a rotating column connected to the central rotation seal at the bottom of the cylinder, a linkage portion connecting the rotating column and the clamping portion, and a power portion for driving the rotating column to rotate.

[0015] Furthermore, the clamping portion includes a plurality of support plates distributed along the inner wall of the cylinder, anti-slip protrusions arranged at intervals on the support plates, and a support plate arranged on the support plates below the anti-slip protrusions, and the support plates surround a clamping channel.

[0016] Furthermore, the linkage part includes a ring plate connected to the bottom of the support plate and a reinforcement rod connecting the ring plate and the rotating column.

[0017] Furthermore, the power unit includes a central gear and a gear ring arranged on the platform, a driven gear meshing with the central gear and the gear ring, a motor for driving the gear ring to rotate, a top support plate for mounting the cylinder, a bracket connecting the top support plate and the platform, a slide groove arranged in an annular manner along the top support plate, and a guide column arranged on the bracket and slidingly matched with the slide groove.

[0018] The invention provides a hemodialysis catheter cleaning device, which has the following beneficial effects: the invention improves the cleaning effect of the threaded opening of the hemodialysis catheter by arranging a brushing part, thereby achieving all-round cleaning of the hemodialysis catheter; when the cleaning liquid enters the guide channel from the through hole, under the guidance of the guide protrusions on the upper and lower brush bristles, the cleaning liquid continuously impacts the central brush bristles, so that the central brush bristles quickly swing in the thread groove of the spiral opening, thereby achieving cleaning of the bottom of the thread groove;

[0019] The present invention arranges a positioning rotating assembly. When the cleaning liquid enters from the water inlet, it flushes the inner wall of the hemodialysis catheter and flows to the bottom of the cylinder body. The ring plate drives the clamping part to rotate under the drive of the rotating column and the reinforcing rod, so that the threaded opening and the brushing part of the hemodialysis catheter slide relative to each other, thereby cleaning the threaded opening.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-5 , a hemodialysis catheter cleaning device, comprising a platform 1, and also comprising

[0027] The cylinder 2 has a positioning and rotating assembly 3 disposed therein for fixing and rotating the hemodialysis catheter;

[0028] The cleaning component 5 includes a cover body 501 arranged on the top of the cylinder 2, a water inlet 502 connected to the center of the cover body 501, a tube body 503 arranged at the bottom of the cover body 501 and connected to the water inlet 502, and a brushing portion 504 spirally distributed along the outer wall of the tube body 503. After the positioning and rotating component 3 drives the hemodialysis catheter to rotate, the brushing portion 504 cleans the spiral opening of the hemodialysis catheter. Preferably, a water outlet 201 can be arranged at the bottom of the cylinder 2, and a lifting component 4 for driving the cover body 501 to rise and fall is arranged on the outside of the cylinder 2. The lifting component 4 in this embodiment can be implemented by a cylinder. When the positioning and rotating component 3 drives the hemodialysis catheter to rotate, the cover body 501 drives the brushing portion 504 spirally distributed on the outer wall of the tube body 503 to rise and fall, thereby ensuring that the brushing portion 504 is always located in the thread groove of the spiral opening.

[0029] In an optional embodiment of the present invention, the brushing portion 504 includes a central bristle 5041, upper bristles 5042 and lower bristles 5043 distributed on both sides of the central bristle 5041, a guide channel 5044 respectively located between the central bristle 5041 and the upper bristles 5042 and the lower bristles 5043, a guide protrusion 5045 arranged at intervals on the upper bristles 5042 and the lower bristles 5043, and a through hole 5046 connecting the guide channel 5044 and the interior of the tube body 503. Preferably, the upper bristles 5042 and the lower bristles 5043 in this embodiment are arranged on the central bristle 5041. 042 and the lower side bristles 5043 are equal in length, and the length of the central bristles 5041 is greater than that of the upper side bristles 5042 and the lower side bristles 5043; the central bristles 5041 are used to brush the bottom of the thread groove of the spiral mouth, and when the cleaning liquid enters the guide channel 5044 from the through hole 5046, under the guidance of the guide protrusions 5045 on the upper side bristles 5042 and the lower side bristles 5043, the cleaning liquid continuously impacts the central bristles 5041, so that the central bristles 5041 swing quickly in the thread groove of the spiral mouth, thereby cleaning the bottom of the thread groove.

[0030] In an optional embodiment of the present invention, the inclination directions of adjacent guide protrusions 5045 are opposite. Preferably, in this embodiment, the hardness of the central bristles 5041 is less than the hardness of the upper bristles 5042 and the lower bristles 5043.

[0031] In an optional embodiment of the present invention, the distance between the guide protrusion 5045 on the upper side bristles 5042 near the through hole 5046 and the through hole 5046 is greater than the distance between the guide protrusion 5045 on the lower side bristles 5043 near the through hole 5046 and the through hole 5046. This arrangement allows the cleaning liquid entering the guide channel 5044 to alternately impact the center bristles 5041 under the guidance of the guide protrusions 5045 on the upper side bristles 5042 and the lower side bristles 5043, thereby increasing the swinging frequency of the center bristles 5041 and thereby improving the cleaning effect on the bottom of the thread groove.

[0032] In an optional embodiment of the present invention, the guide protrusion 5045 on the upper side bristles 5042 near the through hole 5046 is inclined in the direction away from the through hole 5046, and the guide protrusion 5045 on the lower side bristles 5043 near the through hole 5046 is inclined in the direction close to the through hole 5046. After the cleaning liquid enters the guide channel 5044, it flows along the guide protrusion 5045 on the upper side bristles 5042 near the through hole 5046 and impacts the central bristle 5041, while the guide protrusion 5045 on the lower side bristles 5043 near the through hole 5046 blocks the cleaning liquid and delays the cleaning liquid from flowing to the central bristle 5041. After the cleaning liquid passes through the guide protrusion 5045 of the first upper side bristle 5042, it will enter the two adjacent guide protrusions. Between the protrusions 5045, since the inclination direction of the next guide protrusion 5045 is opposite to the inclination direction of the first guide protrusion 5045, the next guide protrusion 5045 will block the cleaning liquid and delay the cleaning liquid from flowing to the central bristle 5041. After being blocked by the first guide protrusion 5045 on the lower side bristles 5043, since the inclination direction of the next guide protrusion 5045 is opposite to the inclination direction of the first guide protrusion 5045, the cleaning liquid will quickly flow along the next guide protrusion 5045 to the central bristle 5041 and impact the central bristle 5041. Under the alternating guidance of the guide protrusions 5045 on the upper side bristles 5042 and the lower side bristles 5043, the central bristle 5041 can swing quickly to clean the bottom of the thread groove.

[0033] In an optional embodiment of the present invention, the positioning rotation assembly 3 includes a clamping portion 301, a rotating column 302 connected to a central rotation seal at the bottom of the cylinder 2, a linkage portion 303 connecting the rotating column 302 and the clamping portion 301, and a power portion 304 for driving the rotating column 302 to rotate. After the clamping portion 301 is used to fix the spiral mouth of the hemodialysis catheter, the rotating column 302 drives the clamping portion 301 to rotate through the linkage portion 303, thereby realizing the rotation of the spiral mouth.

[0034] In an optional embodiment of the present invention, the clamping portion 301 includes a plurality of support plates 3011 distributed along the inner wall of the cylinder 2, anti-slip protrusions 3012 arranged at intervals on the support plates 3011, and a support plate 3013 arranged on the support plates 3011 and below the anti-slip protrusions 3012. The support plates 3011 are surrounded by a clamping channel 3014. Preferably, the anti-slip protrusions 3012 in this embodiment have a semicircular cross-section and are made of rubber material. The surface of the anti-slip protrusions may be provided with longitudinally distributed anti-slip grooves to prevent the spiral mouth from sliding relative to the anti-slip protrusions 3012 during rotation. After the spiral mouth is inserted into the clamping channel 3014, the outer wall of the spiral mouth is in close contact with the anti-slip protrusions 3012. At the same time, the presence of the support plate 3013 can provide positioning and support for the spiral mouth.

[0035] In an optional embodiment of the present invention, the linkage portion 303 includes a ring plate 3031 at the bottom of the support plate 3011 and a reinforcement rod 3032 connecting the ring plate 3031 and the rotating column 302. Preferably, the ring plate 3031 in this embodiment and the bottom of the inner wall of the cylinder 2 have a spacing; when the cleaning liquid enters from the water inlet 502, the inner wall of the hemodialysis catheter is flushed and flows to the bottom of the cylinder 2, and the ring plate 3031 drives the clamping portion 301 to rotate under the drive of the rotating column 302 and the reinforcement rod 3032, so that the threaded port of the hemodialysis catheter and the brushing portion 504 slide relative to each other, thereby cleaning the threaded port.

[0036] In an optional embodiment of the present invention, the power unit 304 includes a central gear 3041 and a gear ring 3042 disposed on the platform 1, a driven gear 3043 meshing with the central gear 3041 and the gear ring 3042 for driving the rotating column 302, a motor 3044 for driving the gear ring 3042 to rotate, a top support plate 3045 for mounting the cylinder 2, a bracket 3046 connecting the top support plate 3045 and the platform 1, a slide groove 3047 annularly arranged along the top support plate 3045, and a guide column 304 disposed on the bracket 3046 and slidingly matched with the slide groove 3047. 8. Preferably, the gear ring 3042 in this embodiment is fixed on the platform 1, the top support plate 3045 is fixedly connected to the cylinder 2, and a U-shaped frame plate for placing the edge of the top support plate 3045 can be provided on the bracket 3046; after the motor 3044 drives the active gear ring 3042 to rotate, the driven gear 3043 rotates and rotates along the gear ring 3042, driving the rotating column 302 to rotate, and at the same time, the top support plate 3045 rotates under the support of the U-shaped frame plate, and is guided by the sliding cooperation of the slide groove 3047 and the guide column 3048, thereby realizing the synchronous cleaning of multiple hemodialysis catheters.
