Technical Field

[0001] The present invention relates to the technical field of coating equipment, in particular to a coating equipment for a medical suction catheter. Background Art

[0002] A medical suction catheter is a tubular device used in the medical field. It primarily uses negative pressure suction to extract fluids, gases, foreign matter, or pathological products, such as blood, sputum, pus, and thrombi, from human tissue or body cavities for diagnostic, therapeutic, or surgical assistance purposes. Advances in medical technology and the widespread use of non-invasive and minimally invasive surgeries have led to the irreplaceable role of medical catheters, guidewires, and stents with hydrophilic, ultra-slippery, antibacterial, anticoagulant, and drug-eluting properties in clinical practice. These functions are achieved through medical coatings applied to the surface of medical devices using specialized coating equipment and methods. Common coating methods include dip coating, spray coating, spin coating, and electrochemical coating. The surface of the suction catheter requires coating, thus requiring coating equipment.

[0010] Preferably, the telescopic end of the cylinder is fixedly mounted on the surface of the sliding bar, and there are two linear actuators, which are symmetrically mounted along the flat plate.

[0011] By extending the telescopic end of the cylinder, a pushing force can be applied to the sliding bar, and the linear sliding of the sliding bar can drive the mobile protective cover to slide together, so that the mobile protective cover is separated from the fixed protective cover, making it convenient to place the medical suction catheter that needs to be coated in the middle of the inside of the fixed protective cover, and again by contracting the telescopic end of the cylinder, a pulling force can be applied to the sliding bar, and the mobile protective cover can be driven to move to the side close to the fixed protective cover for reset, so that the mobile protective cover is matched with the fixed protective cover to wrap the medical suction catheter that needs to be coated to form a shield, and the material sprayed from the nozzle will not form coating overlap, and will not be sprayed to the area that does not need to be coated.

[0012] Preferably, the fixed protective cover is evenly distributed at the edge of the flat surface, the movable protective cover is installed at the same height as the fixed protective cover, the nozzle is installed at an angle, and the flat plate is driven to move linearly downward by the linear drive delivery end, so that the coating assembly as a whole can be driven to move together, thereby driving the nozzle to move linearly, thereby increasing the spraying area of ​​the medical suction catheter.

[0014] Preferably, the output end of the power source is transmission-installed between the connecting screw rod, and the thread directions at both ends of the surface of the connecting screw rod are opposite.

[0015] Preferably, the insertion rods are evenly installed in the middle of the inner side of the U-shaped movable plate, and the guide groove body is installed at an angle.

[0016] The first and second clamping plates are fixedly mounted on the ends of the first and second clamping plates, and the ends of the first and second clamping plates are fixedly mounted on the inner side of the U-shaped bracket. The surface of the second splint is provided with an elliptical hole, and the two ends of the medical suction catheter to be coated are extended to the inside of the elliptical hole, so that the medical suction catheter is in a vertical state, and the connecting screw rod can be driven to rotate by rotating the output end of the power source, and the thread directions at both ends of the surface of the connecting screw rod are opposite, so that the two symmetrical U-shaped moving plates move toward each other, which can drive the insertion rod to move. The end of the insertion rod is inserted into the port of the medical suction catheter, which can support and position the port of the medical suction catheter, so that the medical suction catheter is not easily offset or skewed.

[0017] Preferably, the first clamp and the second clamp are both mounted inside the U-shaped bracket, and the elliptical holes are evenly distributed on the surfaces of the first clamp and the second clamp, and one end of the first slide bar extends into the interior of the guide groove body away from one end of the first clamp, and the second slide bar extends into the interior of the guide groove body away from one end of the second clamp.

[0020] The present invention provides a coating device for a medical suction catheter. The device has the following beneficial effects:

[0021] 1. The coating coating equipment for the medical suction catheter uses a spraying main unit as a power source, can discharge the paint stored inside the spraying main unit into the interior of the spraying main unit, and under the transportation of the hose, the paint is sprayed from the nozzle to the surface of the medical suction catheter, and nozzles are installed on both sides of the medical suction catheter to be coated, and the nozzles are installed at an angle so that the paint sprayed from the nozzles fully contacts the medical suction catheter and is sprayed together in different directions, so that the coating of the medical suction catheter is more uniform.

[0022] 2. The coating equipment for the medical suction catheter uses the telescopic end of the cylinder to apply a pushing force to the sliding bar, so that the linear sliding of the sliding bar can drive the movable protective cover to slide together, so that the movable protective cover is separated from the fixed protective cover, which is convenient for placing the medical suction catheter to be coated in the middle of the inside of the fixed protective cover, and uses the telescopic end of the cylinder to apply a pulling force to the sliding bar, so that the movable protective cover can be driven to move to the side close to the fixed protective cover for reset, so that the movable protective cover is matched with the fixed protective cover to wrap the medical suction catheter to be coated to form a shield, and the material sprayed from the nozzle will not form coating overlap, and will not be sprayed to the area that does not need to be coated.

[0023] 3. The coating coating equipment for the medical suction catheter uses the linear drive conveying end to drive the flat plate to move linearly downward, so that the coating component as a whole can be driven to move together, thereby driving the nozzle to move linearly, thereby increasing the spraying area of ​​the medical suction catheter.

[0024] 4. The coating coating equipment for medical suction catheters, as the flat plate is driven to move by the linear drive conveying end, utilizes the outer cylindrical surface of the roller to fit with the inner side surface of the cabinet, so that the roller rolls, thereby providing rolling support for the flat plate, increasing the support points, making the overall operation of the coating assembly driven by the flat plate smooth and stable, and less prone to shaking, further facilitating the coating of medical suction catheters.

[0025] 5. The coating coating equipment for the medical suction catheter utilizes the rotation of the power source output end to drive the connecting screw to rotate, and combined with the opposite directions of the threads at both ends of the connecting screw surface, the two upper and lower symmetrical U-shaped moving plates move toward each other, which can drive the insertion rod to move. The end of the insertion rod is inserted into the port of the medical suction catheter, which can support and position the port of the medical suction catheter, making it less likely for the medical suction catheter to deviate and skew.

[0026] 6. The coating coating device of the medical suction catheter applies pressing pressure to the ends of the first slide rod and the second slide rod through the inner wall of the guide groove body, which can drive the first clamping plate and the second clamping plate to slide, and the reset spring is compressed, so that the elliptical holes on the first clamping plate and the second clamping plate can be staggered to clamp and fix the end of the medical suction catheter, and the insertion rod is inserted into the interior of the medical suction catheter port to support the medical suction catheter. After the port of the medical suction catheter is clamped, it is not easy to be damaged, which has a protective effect.

[0027] 7. The coating coating equipment for the medical suction catheter uses a heater to heat the internal air into hot air, and discharges the hot air into the interior of the airway. The hot air is sprayed from the outlet of the curved air nozzle onto the surface of the coated medical suction catheter to dry the coating. The outlet of the curved air nozzle is curved, which facilitates the sprayed hot air to fully contact the surface of the medical suction catheter, thereby promoting the drying of the coating.

[0028] 8. The coating coating equipment for the medical suction catheter utilizes an arc-shaped piece to apply an upward pushing force to the bottom of the ball-end rod, and under the elastic support of the elastic telescopic rod, the airway drives the curved air nozzle to move upward. As the arc-shaped piece separates from the bottom end of the ball-end rod, and under the elastic tension of the elastic telescopic rod, the upward pushing force on the ball-end rod disappears, causing the airway to drive the curved air nozzle to move downward for reset. In this way, the curved air nozzle can be moved back and forth to fully dry the coating on the surface of the medical suction catheter. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The staff turns on the cylinder 44 to work, and uses the telescopic end of the cylinder 44 to extend, which can apply a pushing force to the sliding bar 43.

[0050] The second embodiment, based on the first embodiment, see Figures 1 to 8 As shown:

[0051] The fixing mechanism 3 includes a connecting screw 31 and a power source 32. The connecting screw 31 is rotatably installed between the top and bottom of the inner cavity of the cabinet 1, and the power source 32 is fixedly installed at the bottom of the inner cavity of the cabinet 1. Both ends of the surface of the connecting screw 31 are threadedly installed with U-shaped movable plates 33. The bending part of the inner side of the U-shaped movable plate 33 is fixedly connected to a guide groove body 34. The middle of the inner side of the U-shaped movable plate 33 is fixedly connected to an insertion rod 35, and a clamping assembly 36 is installed on the top of the insertion rod 35.

[0052] The output end of the power source 32 is installed in a transmission manner with respect to the connecting screw rod 31 , and the threads at both ends of the surface of the connecting screw rod 31 are in opposite directions.

[0053] The clamping assembly 36 includes a U-shaped bracket 361, which is fixedly connected to the inner side of the cabinet 1 through a right-angle plate, and the end of the insertion rod 35 away from the inner side of the U-shaped movable plate 33 is slidably installed between the U-shaped bracket 361, and the two ends of the U-shaped bracket 361 are respectively slidably installed with a first sliding rod 362 and a second sliding rod 363, and the end of the surface of the first sliding rod 362 is fixedly installed with a first clamping plate 364, and the end of the surface of the second sliding rod 363 is fixedly installed with a second clamping plate 365, and the end of the first clamping plate 364, the end of the second clamping plate 365 and the inner side of the U-shaped bracket 361 are fixedly connected with a reset spring piece 366. The surface of the first splint 364 and the surface of the second splint 365 are both provided with an elliptical hole 367. The two ends of the medical suction catheter to be coated are extended to the inside of the elliptical hole 367, so that the medical suction catheter is in a vertical state, and the power source 32 is turned on to work. The rotation of the output end of the power source 32 can drive the connecting screw 31 to rotate, and the opposite directions of the threads at both ends of the surface of the connecting screw 31 are combined to make the two symmetrical U-shaped movable plates 33 move toward each other, so that the insertion rod 35 can be driven to move. The end of the insertion rod 35 is inserted into the port of the medical suction catheter, so that the port of the medical suction catheter can be supported and positioned.

[0054] The first clamping plate 364 and the second clamping plate 365 are both installed inside the U-shaped bracket 361, and the elliptical holes 367 are evenly distributed on the surface of the first clamping plate 364 and the surface of the second clamping plate 365. The first sliding rod 362 extends from one end of the first clamping plate 364 to the inside of the guide groove body 34, and the second sliding rod 363 extends from one end of the second clamping plate 365 to the inside of the guide groove body 34.

[0055] As the two symmetrical U-shaped movable plates 33 move toward each other and are installed at an angle in combination with the guide groove body 34, pressing pressure is applied to the ends of the first slide bar 362 and the second slide bar 363 through the inner wall of the guide groove body 34, which can drive the first clamping plate 364 and the second clamping plate 365 to slide, and the reset spring piece 366 is compressed, and the elliptical holes 367 on the first clamping plate 364 and the second clamping plate 365 can be staggered to clamp and fix the end of the medical suction catheter, and the insertion rod 35 is inserted into the interior of the medical suction catheter port to support the medical suction catheter. After the port of the medical suction catheter is clamped, it is not easy to be damaged.

[0056] The third embodiment, based on the first and second embodiments, see Figures 1 to 10 As shown:

[0057] An auxiliary mechanism 5 is installed on the top of the flat plate 42. The auxiliary mechanism 5 includes an elastic telescopic rod 51. The bottom of the elastic telescopic rod 51 is fixedly connected to the side of the top of the flat plate 42. An air duct 52 is fixedly installed on the top of the elastic telescopic rod 51. Both ends of the surface of the air duct 52 are fixedly connected to a ball head rod 53. The ball head rod 53 is installed just above the arc-shaped piece 47. A heater 54 is installed at the air inlet on the surface of the air duct 52. The air outlet of the air duct 52 is connected to a bent air nozzle 55. The staff turns on the heater 54 to work, and uses the heater 54 to heat the internal air into hot air, and discharges the hot air into the interior of the air duct 52, and sprays it from the air outlet of the bent air nozzle 55 toward the surface of the coated medical suction catheter for drying. The air outlet of the bent air nozzle 55 is bent, which makes it easy for the sprayed hot air to fully contact the surface of the medical suction catheter to dry the coating.

[0058] The ball head rod 53 is installed vertically, the airway 52 is installed horizontally, and the curved air nozzles 55 are evenly distributed on the surface of the airway 52. ​​As the roller 46 rolls, the arc piece 47 can be driven by the roller 46 to rotate in a circle. The surface of the arc piece 47 contacts the spherical end at the bottom of the ball head rod 53, so that the ball head rod 53 is pushed upward, and under the elastic support of the elastic telescopic rod 51, the airway 52 drives the curved air nozzle 55 to move upward, and as the arc piece 47 separates from the bottom end of the ball head rod 53, and under the elastic tension of the elastic telescopic rod 51, the upward push on the ball head rod 53 disappears, so that the airway 52 drives the curved air nozzle 55 to move downward for reset. In this way, the paint on the surface of the medical suction catheter can be fully dried by using the reciprocating up and down movement of the curved air nozzle 55.

[0059] When in use, the staff first starts the cylinder 44 to work, and uses the telescopic end of the cylinder 44 to extend, which can apply a pushing force to the sliding bar 43. The sliding bar 43 slides linearly, and the movable protective cover 453 can be driven to slide together, so that the movable protective cover 453 is separated from the fixed protective cover 452;

[0060] Extend both ends of the medical suction catheter to be coated into the inside of the elliptical hole 367 so that the medical suction catheter is in a vertical state, and turn on the power source 32 to work. The rotation of the output end of the power source 32 can drive the connecting screw 31 to rotate, and combined with the opposite directions of the threads at both ends of the surface of the connecting screw 31, the two upper and lower symmetrical U-shaped movable plates 33 move toward each other, thereby driving the insertion rod 35 to move. The end of the insertion rod 35 is inserted into the port of the medical suction catheter to support and position the port of the medical suction catheter.

[0061] As the two symmetrical U-shaped movable plates 33 move toward each other and are tilted in combination with the guide slot 34, the inner wall of the guide slot 34 applies pressure to the ends of the first slide bar 362 and the second slide bar 363, thereby driving the first clamping plate 364 and the second clamping plate 365 to slide. When the reset spring 366 is compressed, the elliptical holes 367 on the first clamping plate 364 and the second clamping plate 365 are staggered, thereby clamping and fixing the end of the medical suction catheter.

[0062] The contraction of the telescopic end of the cylinder 44 can be used to apply a pulling force to the sliding bar 43, so that the movable protective cover 453 can be moved to the side close to the fixed protective cover 452 for reset, so that the movable protective cover 453 and the fixed protective cover 452 are matched to wrap the medical suction catheter to be coated to form a shield;

[0063] The staff turns on the spraying main unit 451 to work, and uses the spraying main unit 451 as a power source to discharge the paint stored in the spraying main unit 451 into the interior of the spraying main unit 451. Under the transportation of the hose 456, the paint is sprayed from the nozzle 454 to the surface of the medical suction catheter. The nozzles 454 are installed on both sides of the medical suction catheter to be coated, and the nozzles 454 are installed at an angle so that the paint sprayed from the nozzles 454 fully contacts the medical suction catheter and is sprayed in different directions, so that the coating of the medical suction catheter is more uniform.

[0064] At the same time, the staff starts the linear drive 41 to work, and uses the conveying end of the linear drive 41 to drive the plate 42 to move linearly downward, so that the coating assembly 45 is driven to move together, thereby driving the nozzle 454 to move linearly, thereby increasing the spraying area of ​​the medical suction catheter;

[0065] Moreover, as the plate 42 is driven by the conveying end of the linear drive 41 to move, the outer surface of the roller 46 is in contact with the inner surface of the cabinet 1, so that the roller 46 rolls, thereby providing rolling support for the plate 42, increasing the support points, so that the plate 42 drives the coating assembly 45 to run smoothly and stably.

[0066] The staff turns on the heater 54 to heat the internal air into hot air, and discharges the hot air into the interior of the airway 52. ​​The hot air is then sprayed from the outlet of the bent air nozzle 55 onto the surface of the coated medical suction tube to dry the tube. The outlet of the bent air nozzle 55 is bent, so that the sprayed hot air can fully contact the surface of the medical suction tube.

[0067] As the roller 46 rolls, the arc-shaped piece 47 can be driven by the roller 46 to rotate in a circle. The surface of the arc-shaped piece 47 contacts the spherical end at the bottom of the ball head rod 53, so that the ball head rod 53 is pushed upward, and under the elastic support of the elastic telescopic rod 51, the air channel 52 drives the bent air nozzle 55 to move upward. As the arc-shaped piece 47 separates from the bottom end of the ball head rod 53, and under the elastic tension of the elastic telescopic rod 51, the upward push on the ball head rod 53 disappears, so that the air channel 52 drives the bent air nozzle 55 to move downward for reset. In this way, the paint on the surface of the medical suction catheter can be fully dried by the reciprocating up and down movement of the bent air nozzle 55.
