Description

Technical Field

[0001] The invention relates to the technical field of medical catheter coatings, in particular to an antibacterial and anti-sticking latex catheter surface coating device. Background Art

[0002] Antibacterial and anti-stick latex catheter, a medical product that combines the flexibility and antibacterial and anti-stick properties of latex materials, is designed to provide a more comfortable and safer catheterization experience. Latex catheters are usually made of natural latex or synthetic latex, with good flexibility and biocompatibility, and can adapt to the anatomical structure of different patients, reducing friction and discomfort during intubation. Antibacterial agents are added to the antibacterial and anti-stick latex catheter during the manufacturing process, which can effectively inhibit the growth of bacteria and reduce the risk of urinary tract infection. At the same time, its surface has been specially treated with anti-stick properties, which can reduce the adhesion of urine and bacteria and keep the catheter clean and unobstructed. This type of catheter can significantly reduce the risk of urinary tract infection when in use and ensure the safety of patients. Its good flexibility can reduce the discomfort during intubation and improve the comfort of patients.

[0003] The antibacterial properties of the coating effectively inhibit the growth and reproduction of bacteria and reduce the risk of urinary tract infection. This can be achieved by adding antibacterial agents to the coating. Silver nanoparticles are widely used due to their broad-spectrum antibacterial activity and low toxicity. They can play an antibacterial role by destroying bacterial cell membranes and inhibiting bacterial enzyme activity. Anti-stick coatings can reduce the adhesion of bacteria and other biomolecules on the surface of catheters, thereby preventing the formation of biofilms. Currently, most coating devices use immersion to coat medical catheters. This method can easily lead to uneven thickness of the coating layer on the surface of the catheter, and it is difficult to recycle the dripping coating liquid in the existing coating device, which can easily lead to waste of resources.

Detailed implementation manners

[0038] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figure 1-10In an embodiment of the present invention, an antibacterial and anti-stick latex catheter surface coating device includes: a collecting mechanism 100, the collecting mechanism 100 is used to collect excess coating liquid generated during catheter coating; a coating mechanism 200, the coating mechanism 200 is used to transport the coating liquid and apply the coating liquid to the outer wall of the catheter, the coating mechanism 200 includes a cavity ring 201, a tooth ring 202 is fixedly sleeved on the outer wall of the cavity ring 201, three limiting grooves 203 are equidistantly provided in an annular manner on the inner wall of the cavity ring 201, hollow blocks 205 are slidably embedded and connected in the three limiting grooves 203, an infusion shaft 206 connected to the inside of the two hollow blocks 205 is rotatably connected between the two hollow blocks 205, a coating tube 207 is fixedly connected between the two infusion shafts 206, and a plurality of liquid outlet holes 208 are equidistantly provided in an annular manner on the outer wall of the coating tube 207; and a smoothing mechanism 300, the smoothing mechanism 300 is used to evenly scrape the coating liquid on the surface of the catheter. The outer walls of the two round bucket covers 102 are fixedly connected with a collecting plate 104, and the collecting plate 104 is connected to the inside of the liquid storage box 105. A shaped frame 209 is rotatably connected between the two infusion shafts 206, and one end of an electric rod 210 is fixedly connected to the center of the shaped frame 209, and the electric rod 210 is fixedly connected to the inner wall of the cavity ring 201. Six connecting columns 204 connected to the inside of the cavity ring 201 are fixedly connected in an annular shape at equal distances, and the inner top of the connecting column 204 is slidably connected with a closing cover 212, and the closing cover 212 is fixedly connected with a reset spring 213. A support rod 211 is fixedly connected to the inner wall of the hollow block 205, and the support rod 211 conflicts with the closing cover 212.

[0040] Specifically, the urinary catheter is transported from the center of the two round bucket covers 102, and the electric rod 210 drives the mold frame 209 and the coating cylinder 207 to move in the cavity ring 201, which will drive the three coating cylinders 207 to stick to the surface of the urinary catheter. At the same time, the hollow blocks 205 at both ends of the mold frame 209 will slide to the bottom of the limiting groove 203, so that the hollow blocks 205 will be plugged into the connecting column 204, so that the support rod 211 inside the hollow block 205 can push the closing cover 212 to slide downward. At this time, the closing cover 212 no longer closes the top of the connecting column 204, so that the coating liquid inside the cavity ring 201 will pass through the connecting column 204, The hollow block 205 and the infusion shaft 206 are transported to the coating cylinder 207, and the coating liquid flows out through the multiple liquid outlet holes 208 of the coating cylinder 207 to coat the surface of the catheter.

[0041] During coating, the dripping coating liquid will fall on the inner wall of the round bucket cover 102.

During coating, the output end of the driving motor 218 will drive the spiral conveying plate 217 in the riser 216 to rotate, and then the coating liquid in the liquid storage tank 105 will be transported upward to the hose 214, and then discharged into the cavity ring 201 through the hose 214, so that the effect of recycling can be achieved, and the utilization rate of resources is improved;

[0042] The output end of the servo motor 302 drives the rotating shaft 1 303 and the driving round seat 304 to rotate. Since the lever 305 at the bottom of the driving round seat 304 slides in the slide rail 306, when the driving round seat 304 rotates, the lever 305 drives the slide rail 306 and the rack column 307 to slide back and forth on the support frame 301, and the bottom of the rack column 307 is meshed with the gear ring 202, thereby driving the cavity ring 201 to reciprocate, so that the three coating cylinders 207 can roll back and forth on the surface of the catheter, thereby increasing the coating area of ​​the coating, so that the surface of the catheter can be completely attached with the coating liquid, avoiding the problem of missing coating;

[0043] The rotating shaft 1 303 in the smoothing mechanism 300 can drive the bevel gear 1 308 and the bevel gear 2 309 to mesh and rotate, and then the bevel gear 2 309 can drive the rotating shaft 2 310 and the spur gear 311 at the end to rotate, and the spur gear 311 can drive the circular tooth plate 312 at the bottom to rotate in the annular frame 314, and the soft rope 316 can be gradually released through the three electric rods 2 318, and then the plane plate 315 rotates under the pressure of the compression spring 320 until the liquid wiping piece 319 at the end of the plane plate 315 fits with the surface of the catheter, and the rotation of the circular tooth plate 312 can simultaneously drive the three liquid wiping pieces 319 to scrape the coating liquid on the surface of the catheter, so that the coating thickness on the surface of the catheter can be scraped to a consistent thickness, thereby improving the coating effect on the catheter.
