Description

Technical Field

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

[0002] A medical suction catheter is a tubular instrument used in the medical field. It mainly uses the principle of negative pressure suction to extract liquids, gases, foreign bodies or pathological products in human tissues or body cavities, such as blood, sputum, pus, thrombus, etc., in order to achieve the purpose of diagnosis, treatment or surgical assistance. With the progress of medical technology and the extensive application of minimally invasive non-surgical operations, medical catheters, guide wires, stents, etc. with hydrophilic super-slippery, antibacterial, anticoagulant, and drug elution functions have played an irreplaceable role in clinical practice. These functions are all achieved on the surface of medical devices through medical coatings with special coating equipment and coating methods. Commonly used coatings include dip coating, spray coating, spin coating, and electrochemical coating. Since the surface of the suction catheter needs to be coated, coating equipment is required.

[0003] Currently, when coating the surface of a suction catheter, in order to improve coating efficiency, multiple suction catheters are often arranged for coating, which easily leads to coating overlap and uneven coating. Moreover, the areas that do not need to be coated will also be contaminated by the coating material. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A coating equipment for a medical suction catheter, comprising: A cabinet, and a control box installed on the side of the cabinet surface. A fixing mechanism is installed inside the cabinet; A processing mechanism for coating the surface of a medical suction catheter. The processing mechanism is installed in the middle of the inner cavity of the cabinet; Among them, the processing mechanism includes a linear driver and a flat plate. The linear driver is fixedly installed in the middle of the inner side of the cabinet, and the flat plate is fixedly connected to the output end of the linear driver. A sliding bar is slidably installed at the side of the top of the flat plate, a cylinder is fixedly installed at one end of the top of the flat plate, a coating assembly is installed on the surface of the flat plate, and rollers are rotatably installed at both ends of the flat plate. An arc-shaped piece is fixedly connected to the edge of the surface of the roller. When the flat plate is driven by the conveying end of the linear driver to move, the outer circular surface of the roller is attached to the inner side of the cabinet, causing the roller to roll, so as to roll and support the flat plate, increasing the support points, making the flat plate drive the coating assembly to operate smoothly and stably as a whole, not easily shaking, and further helping to coat the medical suction catheter; The coating assembly includes a spraying main machine and a fixed protective cover. The spraying main machine is installed on the side of the flat surface. The fixed protective cover is fixedly connected to the surface of the flat and on the side far from the spraying main machine. A movable protective cover is fixedly connected to the surface of the sliding bar. Nozzles are fixedly installed on the tops of both the fixed protective cover and the movable protective cover. The discharge port of the spraying main machine is communicated with a circular tube, and a flexible tube is communicated between the circular tube and the nozzle. Using the spraying main machine as the power, the paint stored inside the spraying main machine can be discharged into it, and under the transportation of the flexible tube, the paint is sprayed from the nozzle onto the surface of the medical suction catheter. Moreover, since nozzles are installed on both sides of the medical suction catheter to be coated and the nozzles are installed obliquely, the paint sprayed from the nozzles can fully contact the medical suction catheter and be sprayed in different directions together, making the coating of the medical suction catheter more uniform.

[0005] Preferably, the telescopic end of the cylinder is fixedly installed on the surface of the sliding bar. There are two linear drivers, and the two linear drivers are symmetrically installed along the flat.

[0006] By extending the telescopic end of the cylinder, a driving force can be applied to the sliding bar. Using the linear sliding of the sliding bar, the movable protective cover can be driven to slide together, separating the movable protective cover from the fixed protective cover, facilitating the placement of the medical suction catheter to be coated in the middle inside the fixed protective cover. Then, by contracting the telescopic end of the cylinder again, a pulling force can be applied to the sliding bar, and the movable protective cover can be driven to move towards the side close to the fixed protective cover for resetting. Thus, by fitting the movable protective cover with the fixed protective cover, the medical suction catheter to be coated is wrapped to form an occlusion, so that the discharged material sprayed from the nozzle will not form coating overlap and will not spray material to the area that does not need to be coated.

[0007] Preferably, the fixed protective covers are evenly distributed at the edge of the flat surface. The movable protective cover and the fixed protective cover are installed at the same height, and the nozzles are installed obliquely. By driving the flat to move linearly downward by the driving end of the linear driver, the whole coating assembly can be driven to move together, so that the nozzles are driven to move linearly, and the spraying area of the medical suction catheter can be increased.

[0008] Preferably, the fixing mechanism includes a connecting lead screw and a power source. The connecting lead screw is rotatably installed between the top and bottom of the inner cavity of the cabinet. The power source is fixedly installed at the bottom of the inner cavity of the cabinet. U-shaped moving plates are threadedly installed at both ends of the surface of the connecting lead screw. A guiding groove body is fixedly connected to the bent part of the inner side of the U-shaped moving plate. A plug rod is fixedly connected to the middle of the inner side of the U-shaped moving plate. A clamping assembly is installed at the top of the plug rod.

[0009] Preferably, the output end of the power source is installed in a transmission manner with the connecting lead screw, and the thread directions at both ends of the surface of the connecting lead screw are opposite.

[0010] Preferably, the insertion rods are evenly installed at the middle of the inner side surface of the U-shaped moving plate, and the guiding groove body is installed obliquely.

[0011] Preferably, the clamping assembly includes a U-shaped bracket. The U-shaped bracket is fixedly connected to the inner side surface of the cabinet through a right-angle plate. One end of the insertion rod away from the inner side surface of the U-shaped moving plate is slidably installed with the U-shaped bracket. First sliding rods and second sliding rods are respectively slidably installed at both ends of the U-shaped bracket. A first clamping plate is fixedly installed at the end of the surface of the first sliding rod, and a second clamping plate is fixedly installed at the end of the surface of the second sliding rod. Reset elastic pieces are fixedly connected between the ends of the first clamping plate and the second clamping plate and the inner side surface of the U-shaped bracket. Oval holes are formed on the surfaces of the first clamping plate and the second clamping plate. Both ends of the medical suction catheter to be coated are extended into the interior of the oval holes, so that the medical suction catheter is in a vertical state. By using the rotation of the output end of the power source, the connecting lead screw can be driven to rotate. Considering that the thread directions at both ends of the surface of the connecting lead screw are opposite, the two U-shaped moving plates that are symmetrically arranged up and down move towards each other, so that the insertion rods can be driven to move. The end of the insertion rod is inserted into the port of the medical suction catheter, so that the port of the medical suction catheter can be supported and positioned, and the medical suction catheter is not likely to deviate or skew.

[0012] Preferably, both the first clamping plate and the second clamping plate are installed inside the U-shaped bracket. The oval holes are evenly distributed on the surfaces of the first clamping plate and the second clamping plate. One end of the first sliding rod away from the first clamping plate extends into the interior of the guiding groove body, and one end of the second sliding rod away from the second clamping plate extends into the interior of the guiding groove body. As the two symmetrically arranged U-shaped moving plates move towards each other, considering that the guiding groove body is installed obliquely, by applying a pressing force to the ends of the first sliding rod and the second sliding rod through the inner wall of the guiding groove body, the first clamping plate and the second clamping plate can be driven to slide, and the reset elastic pieces are compressed. By using the fact that the positions of the oval holes on the first clamping plate and the second clamping plate are staggered, the end of the medical suction catheter can be clamped and fixed. And when the insertion rod is inserted into the port of the medical suction catheter, the medical suction catheter can be supported. After the port of the medical suction catheter is clamped, it is not likely to be damaged, achieving a protective effect.

[0013] Preferably, an auxiliary mechanism is installed on the top of the flat plate. The auxiliary mechanism includes an elastic telescopic rod. The bottom of the elastic telescopic rod is fixedly connected to the side of the top of the flat plate. The top of the elastic telescopic rod is fixedly installed with an air duct. Both ends of the surface of the air duct are fixedly connected with ball head rods. The ball head rods are installed directly above the arc-shaped pieces. A heater is installed at the air inlet of the air duct surface. The air outlet of the air duct is communicated with a bent spray nozzle. The heater is used to heat the internal air into hot air, and the hot air is discharged into the air duct, and is sprayed out from the air outlet of the bent spray nozzle onto the surface of the coated medical suction catheter, so as to carry out drying. Moreover, the air outlet of the bent spray nozzle is bent, which is convenient for the sprayed hot air to fully contact the surface of the medical suction catheter and promote the drying of the coating.

[0014] Preferably, the ball head rods are installed vertically, the air duct is installed horizontally, and the bent spray nozzles are evenly distributed on the surface of the air duct. As the roller rolls, the arc-shaped piece can be driven to rotate in a circle by the roller. By using the contact between the surface of the arc-shaped piece and the spherical end at the bottom of the ball head rod, the ball head rod receives an upward driving force. And under the elastic support of the elastic telescopic rod, the air duct drives the bent spray nozzle to move upward. And along with the separation of the arc-shaped piece from the bottom end of the ball head rod, and under the elastic pulling force of the elastic telescopic rod, the upward driving force received by the ball head rod disappears, so that the air duct drives the bent spray nozzle to move downward for reset. In this way, by using the up and down reciprocating movement of the bent spray nozzle, the coating on the surface of the medical suction catheter can be fully dried.

[0015] The present invention provides a coating application device for a medical suction catheter. It has the following beneficial effects: First, for the coating application device of the medical suction catheter, using the spraying host as the power, the coating stored in the spraying host can be discharged into the inside, and under the transportation of the hose, the coating is sprayed from the nozzle onto the surface of the medical suction catheter. And by installing nozzles on both sides of the medical suction catheter to be coated, and using the inclined installation of the nozzles, the coating sprayed by the nozzles can fully contact the medical suction catheter, and spraying is carried out together in different directions, so that the coating of the medical suction catheter is more uniform.

[0016] Second, for the coating application device of the medical suction catheter, the telescopic end of the air cylinder applies a driving force to the sliding bar, causing the linear sliding of the sliding bar, which can drive the movable protective cover to slide together, separating the movable protective cover from the fixed protective cover. This facilitates placing the medical suction catheter to be coated in the middle inside the fixed protective cover. Then, by applying a pulling force to the sliding bar with the telescopic end of the air cylinder, the movable protective cover can be driven to move towards the side close to the fixed protective cover for resetting. Thus, by fitting the movable protective cover with the fixed protective cover, the medical suction catheter to be coated can be wrapped to form an occlusion, preventing the coating material ejected from the nozzle from forming coating overlap and preventing spraying on areas that do not require coating.

[0017] Third, for the coating application device of the medical suction catheter, the conveying end of the linear actuator drives the flat plate to move downward in a straight line, which can drive the entire coating assembly to move together, thereby driving the nozzle to move in a straight line, increasing the spraying area of the medical suction catheter.

[0018] Fourth, for the coating application device of the medical suction catheter, when the flat plate is driven to move by the conveying end of the linear actuator, the outer circular surface of the roller is in contact with the inner side surface of the cabinet, causing the roller to roll, which can provide rolling support for the flat plate, increasing the support points and enabling the flat plate to drive the entire coating assembly to operate smoothly and stably without easy shaking, further facilitating the coating of the medical suction catheter.

[0019] Fifth, for the coating application device of the medical suction catheter, the rotation of the output end of the power source drives the connecting lead screw to rotate. Considering that the thread directions at both ends of the surface of the connecting lead screw are opposite, the two U-shaped moving plates symmetrically arranged up and down move towards each other, driving the insertion rod to move. The end of the insertion rod is inserted into the port of the medical suction catheter, providing support and positioning for the port of the medical suction catheter, preventing the medical suction catheter from being easily offset or skewed.

[0020] Sixth, for the coating application device of the medical suction catheter, by applying a pressing force to the ends of the first sliding rod and the second sliding rod through the inner wall of the guiding groove body, the first clamping plate and the second clamping plate can be driven to slide, and the reset elastic piece is compressed. By staggering the positions of the oval holes on the first clamping plate and the second clamping plate, the end of the medical suction catheter can be clamped and fixed. And with the insertion rod inserted into the interior of the port of the medical suction catheter, support can be provided for the medical suction catheter. After the port of the medical suction catheter is clamped, it is not easily damaged, achieving a protective effect.

[0021] VII. The coating equipment for the medical aspiration catheter heats the internal air into hot air by using a heater, discharges the hot air into the interior of the air duct, and sprays it onto the surface of the coated medical aspiration catheter from the air outlet of the bent nozzle, so as to carry out drying. Moreover, the air outlet of the bent nozzle is bent, which is convenient for the sprayed hot air to fully contact the surface of the medical aspiration catheter and promote the drying of the coating.

[0022] VIII. The coating equipment for the medical aspiration catheter applies an upward pushing force to the bottom of the ball head rod by using an arc-shaped piece. Under the elastic support of the elastic telescopic rod, the air duct drives the bent nozzle to move upward. Along with the separation of the arc-shaped piece from the bottom end of the ball head rod, and under the elastic pulling force of the elastic telescopic rod, the upward pushing force on the ball head rod disappears, causing the air duct to drive the bent nozzle to move downward for reset. In this way, by using the reciprocating up and down movement of the bent nozzle, the coating on the surface of the medical aspiration catheter can be fully dried. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The first embodiment is as Figures 1 to 5 shown. The present invention provides a technical solution: A coating application device for a medical suction catheter, comprising: A cabinet 1 and a control box 2 installed on the side of the surface of the cabinet 1. A fixing mechanism 3 is installed inside the cabinet 1; A processing mechanism 4 for coating and processing the surface of the medical suction catheter. The processing mechanism 4 is installed in the middle of the inner cavity of the cabinet 1; Among them, the processing mechanism 4 includes a linear actuator 41 and a flat plate 42. The linear actuator 41 is fixedly installed in the middle of the inner side surface of the cabinet 1. The flat plate 42 is fixedly connected to the output end of the linear actuator 41. A sliding strip 43 is slidably installed on the side of the top of the flat plate 42. A cylinder 44 is fixedly installed at one end of the top of the flat plate 42. A coating assembly 45 is installed on the surface of the flat plate 42. Rollers 46 are rotatably installed at both ends of the flat plate 42. An arc-shaped piece 47 is fixedly connected to the edge of the surface of the roller 46. When the flat plate 42 is driven by the conveying end of the linear actuator 41 to move, by using the outer circumferential surface of the roller 46 to fit with the inner side surface of the cabinet 1, the roller 46 can roll, so as to roll and support the flat plate 42, increasing the support points and making the overall operation of the flat plate 42 driving the coating assembly 45 smooth and stable; The telescopic end of the cylinder 44 is fixedly installed on the surface of the sliding bar 43. There are two linear drivers 41, and the two linear drivers 41 are symmetrically installed along the flat plate 42.

[0027] The coating assembly 45 includes a spraying main body 451 and a fixed protective cover 452. The spraying main body 451 is installed at the side of the surface of the flat plate 42. The fixed protective cover 452 is fixedly connected to the surface of the flat plate 42 and on the side away from the spraying main body 451. A movable protective cover 453 is fixedly connected to the surface of the sliding bar 43. Nozzles 454 are fixedly installed on the tops of both the fixed protective cover 452 and the movable protective cover 453. The discharge port of the spraying main body 451 is communicated with a circular pipe 455, and a hose 456 is communicated between the circular pipe 455 and the nozzle 454. When the staff turns on the spraying main body 451 to work, using the spraying main body 451 as the power, the paint stored inside the spraying main body 451 can be discharged into the inside, and under the transportation of the hose 456, the paint is sprayed from the nozzle 454 onto the surface of the medical suction catheter. And because nozzles 454 are installed on both sides of the medical suction catheter to be coated, and the nozzles 454 are installed obliquely, the paint sprayed from the nozzles 454 can fully contact the medical suction catheter, and spraying is carried out together in different directions, so that the coating of the medical suction catheter is more uniform.

[0028] When the staff turns on the cylinder 44 to work, by using the elongation of the telescopic end of the cylinder 44, a driving force can be applied to the sliding bar 43. By using the linear sliding of the sliding bar 43, 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, which is convenient for placing the medical suction catheter to be coated in the middle inside the fixed protective cover 452. And by using the contraction of the telescopic end of the cylinder 44 again, a pulling force can be applied to the sliding bar 43, and then the movable protective cover 453 can be driven to move toward the side close to the fixed protective cover 452 for resetting. Thus, by the fitting of the movable protective cover 453 and the fixed protective cover 452, the medical suction catheter to be coated is wrapped to form a shield.

[0029] The fixed protective covers 452 are evenly distributed at the edge of the surface of the flat plate 42. The movable protective cover 453 and the fixed protective cover 452 are installed at the same height. The nozzles 454 are installed obliquely. When the staff turns on the linear driver 41 to work, by using the conveying end of the linear driver 41 to drive the flat plate 42 to move linearly downward, the whole coating assembly 45 can be driven to move together, so that the nozzle 454 is driven to move linearly, increasing the spraying area of the medical suction catheter.

[0030] Second embodiment, on the basis of the first embodiment, please refer to Figures 1 to 8 as shown in The fixing mechanism 3 includes a connecting lead screw 31 and a power source 32. The connecting lead 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 lead screw 31 are threadedly installed with U-shaped moving plates 33. A guiding groove body 34 is fixedly connected to the bent part of the inner side surface of the U-shaped moving plate 33, and a plug rod 35 is fixedly connected to the middle part of the inner side surface of the U-shaped moving plate 33. A clamping assembly 36 is installed at the top of the plug rod 35.

[0031] The output end of the power source 32 is drivingly installed with the connecting lead screw 31, and the thread directions at both ends of the surface of the connecting lead screw 31 are opposite.

[0032] The clamping assembly 36 includes a U-shaped bracket 361. The U-shaped bracket 361 is fixedly connected to the inner side surface of the cabinet 1 through a right-angle plate. One end of the plug rod 35 away from the inner side surface of the U-shaped moving plate 33 is slidably installed with the U-shaped bracket 361. A first sliding rod 362 and a second sliding rod 363 are respectively slidably installed at both ends of the U-shaped bracket 361. A first clamping plate 364 is fixedly installed at the end of the surface of the first sliding rod 362, and a second clamping plate 365 is fixedly installed at the end of the surface of the second sliding rod 363. A reset elastic piece 366 is fixedly connected between the end of the first clamping plate 364, the end of the second clamping plate 365 and the inner side surface of the U-shaped bracket 361. Oval holes 367 are formed on the surfaces of the first clamping plate 364 and the second clamping plate 365. Both ends of the medical suction catheter to be coated are extended into the interior of the oval holes 367, so that the medical suction catheter is in a vertical state, and the power source 32 is turned on for work. By using the rotation of the output end of the power source 32, the connecting lead screw 31 can be driven to rotate. Considering that the thread directions at both ends of the surface of the connecting lead screw 31 are opposite, the two U-shaped moving plates 33 that are symmetrically arranged up and down move towards each other, and then the plug rod 35 can be driven to move. The end of the plug rod 35 is inserted into the port of the medical suction catheter, so as to support and position the port of the medical suction catheter.

[0033] Both the first clamping plate 364 and the second clamping plate 365 are installed inside the U-shaped bracket 361. The oval holes 367 are evenly distributed on the surfaces of the first clamping plate 364 and the second clamping plate 365. One end of the first sliding rod 362 away from the first clamping plate 364 extends into the interior of the guiding groove body 34, and one end of the second sliding rod 363 away from the second clamping plate 365 extends into the interior of the guiding groove body 34.

[0034] As the two symmetrical U-shaped moving plates 33 move towards each other and the guiding groove body 34 is installed obliquely, a pressing force is applied to the ends of the first sliding rod 362 and the second sliding rod 363 through the inner wall of the guiding groove body 34, so as to drive the first clamping plate 364 and the second clamping plate 365 to slide, and the reset elastic piece 366 is compressed. By using the staggered positions of the oval holes 367 on the first clamping plate 364 and the second clamping plate 365, the end of the medical suction catheter can be clamped and fixed. And the insertion rod 35 is inserted into the port of the medical suction catheter to support the medical suction catheter. After the port of the medical suction catheter is clamped, it is not easy to be damaged.

[0035] The third embodiment is based on the first and second embodiments. Please refer to Figures 1 to 10 as shown in 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. The top end of the elastic telescopic rod 51 is fixedly installed with an air duct 52. Both ends of the surface of the air duct 52 are fixedly connected with ball head rods 53. The ball head rods 53 are installed directly above the arc-shaped piece 47. A heater 54 is installed at the air inlet of the air duct 52. The air outlet of the air duct 52 is communicated with a bent nozzle 55. The staff turns on the heater 54 to work. The heater 54 heats the internal air into hot air, discharges the hot air into the air duct 52, and sprays it from the air outlet of the bent nozzle 55 onto the surface of the coated medical suction catheter, so as to dry it. And the air outlet of the bent nozzle 55 is bent, which is convenient for the sprayed hot air to fully contact the surface of the medical suction catheter to dry the coating.

[0036] The ball head rods 53 are installed vertically, the air duct 52 is installed horizontally, and the bent nozzles 55 are evenly distributed on the surface of the air duct 52. As the roller 46 rolls, the arc-shaped piece 47 can be driven to rotate in a circle by the roller 46. By using the contact between the surface of the arc-shaped piece 47 and the spherical end at the bottom of the ball head rod 53, the ball head rod 53 is pushed upward. And under the elastic support of the elastic telescopic rod 51, the air duct 52 drives the bent nozzle 55 to move upward. And along with the separation of the arc-shaped piece 47 from the bottom end of the ball head rod 53, and under the elastic tension of the elastic telescopic rod 51, the upward pushing force on the ball head rod 53 disappears, so that the air duct 52 drives the bent nozzle 55 to move downward to reset. In this way, by using the reciprocating movement of the bent nozzle 55 up and down, the coating on the surface of the medical suction catheter can be fully dried.

[0037] During use, first, the staff member activates the cylinder 44 to operate. By extending the telescopic end of the cylinder 44, a driving force can be exerted on the sliding bar 43. Using the linear sliding of the sliding bar 43, the movable protective cover 453 can be driven to slide together, separating the movable protective cover 453 from the fixed protective cover 452. Extend both ends of the medical suction catheter to be coated into the interior of the oval hole 367, making the medical suction catheter in a vertical state, and activate the power source 32 to operate. By rotating the output end of the power source 32, the connecting lead screw 31 can be driven to rotate. Considering that the thread directions at both ends of the surface of the connecting lead screw 31 are opposite, the two symmetrically arranged U-shaped moving plates 33 move towards each other, driving the insertion rod 35 to move. The end of the insertion rod 35 is inserted into the port of the medical suction catheter, enabling support and positioning of the port of the medical suction catheter. Moreover, as the two symmetrically arranged U-shaped moving plates 33 move towards each other, and considering the inclined installation of the guide groove body 34, by applying a pressing force to the ends of the first sliding rod 362 and the second sliding rod 363 through the inner wall of the guide groove body 34, the first clamping plate 364 and the second clamping plate 365 can be driven to slide, and the reset elastic piece 366 is compressed. By staggering the positions of the oval holes 367 on the first clamping plate 364 and the second clamping plate 365, the end of the medical suction catheter can be clamped and fixed. Then, by contracting the telescopic end of the cylinder 44 again, a pulling force can be exerted on the sliding bar 43, driving the movable protective cover 453 to move towards the side close to the fixed protective cover 452 for reset. Thus, by the coincidence of the movable protective cover 453 and the fixed protective cover 452, the medical suction catheter to be coated is wrapped to form a shield. And the staff member activates the spraying main machine 451 to operate. Using the spraying main machine 451 as the power, the paint stored inside the spraying main machine 451 can be discharged into the interior, and under the conveyance of the hose 456, the paint is sprayed from the nozzle 454 onto the surface of the medical suction catheter. Considering that nozzles 454 are installed on both sides of the medical suction catheter to be coated, and the nozzles 454 are inclinedly installed, the paint ejected from the nozzles 454 can fully contact the medical suction catheter and is sprayed in different directions simultaneously, making the coating of the medical suction catheter more uniform. Meanwhile, the staff member activates the linear driver 41 to operate. By driving the flat plate 42 to move linearly downward through the conveying end of the linear driver 41, the entire coating assembly 45 can be driven to move together, thereby driving the nozzle 454 to move linearly, increasing the spraying area of the medical suction catheter. Moreover, as the flat plate 42 is driven by the conveying end of the linear driver 41 to move, the outer circumferential surface of the roller 46 is attached to the inner side surface of the cabinet 1, causing the roller 46 to roll, so as to provide rolling support for the flat plate 42, increasing the support points and enabling the flat plate 42 to drive the coating assembly 45 to operate smoothly and steadily as a whole; And the staff turns on the heater 54 to work. The heater 54 heats the internal air into hot air, discharges the hot air into the inside of the air duct 52, and sprays it out from the air outlet of the bent nozzle 55 onto the surface of the coated medical suction catheter, so as to carry out drying. The air outlet of the bent nozzle 55 is bent, which is convenient for the sprayed hot air to fully contact the surface of the medical suction catheter; As the roller 46 rolls, the arc-shaped piece 47 can be driven by the roller 46 to rotate circumferentially. The surface of the arc-shaped piece 47 contacts the spherical end at the bottom of the ball head rod 53, causing the ball head rod 53 to receive an upward driving force. Under the elastic support of the elastic telescopic rod 51, the air duct 52 drives the bent nozzle 55 to move upward. Along with the separation of the arc-shaped piece 47 from the bottom end of the ball head rod 53, and under the elastic pulling force of the elastic telescopic rod 51, the upward driving force received by the ball head rod 53 disappears, causing the air duct 52 to drive the bent nozzle 55 to move downward for resetting. In this way, by using the reciprocating up and down movement of the bent nozzle 55, the coating on the surface of the medical suction catheter can be fully dried.
