Description

Technical Field

[0001] This utility model relates to the field of biocompatible coating preparation technology, and in particular to a biocompatible coating preparation device. Background Technology

[0002] Biocompatibility refers to the ability of a material or device to perform its intended function without causing harmful reactions when in contact with living organisms. Simply put, it's the property of a material to "coexist peacefully" with living organisms. In fields such as medicine and bioengineering, materials need to be in long-term or short-term contact with the human body. Therefore, materials must possess good biocompatibility to ensure they do not cause inflammation, immune responses, or other adverse reactions.

[0003] Tantalum metal is widely used in the fabrication of surface coatings for orthopedic implants and cardiovascular stents due to its excellent corrosion resistance, low immunogenicity, and osseointegration capabilities. Taking a porous platinum framework biocompatible tantalum metal coating as an example, the preparation process involves placing tantalum metal powder in a reaction apparatus, then evacuating and heating it. After heating, chlorine gas is introduced into the reaction apparatus. The chlorine gas reacts with the tantalum powder to generate the precursor tantalum pentachloride. This tantalum pentachloride undergoes a reduction reaction with hydrogen to produce pure tantalum, which is then deposited on the porous platinum surface to obtain the tantalum metal coating.

[0004] Throughout the preparation process, impurities in the introduced chlorine gas can affect the preparation results and thus the quality of the coating. For example, if the chlorine gas has a high water vapor content, the moisture will react with tantalum at high temperatures to form tantalum oxide, which will reduce the purity of the target product. If the chlorine gas is affected by external factors during transport and contains impurities, it will also lead to an impure product, and blockages may even occur during transport.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] According to one embodiment of the present invention, in conjunction with Figures 1-5 The diagram shows a biocompatible coating preparation apparatus, including a reactor 1, with an air inlet assembly 2 disposed on one side of the reactor 1.

[0025] In this embodiment, the air intake assembly 2 includes a connecting pipe 21 fixedly connected to the outer surface of the reactor 1, a filter box 22 fixedly connected to one end of the connecting pipe 21, a first box cover 23 movably connected to the top of the filter box 22, a filter plate 24 and a drying box 25 movably connected from top to bottom inside the filter box 22, and an air intake pipe 26 fixedly connected to the top of the first box cover 23. The outer surface of the drying box 25 has a vent hole 252, a box cover 251 movably connected to one side of the drying box 25, a desiccant placed inside the drying box 25, a first valve 211 fixedly connected to the outer surface of the connecting pipe 21, and a support plate 221 fixedly connected between the filter box 22 and the reactor 1. Reactor 1 is the main container for coating preparation. The inlet pipe 26 is connected to an external gas source to introduce the external gas into the filter box 22. In addition to desiccant, the drying box 25 can also be used to place other types of purifying materials as needed. When the external gas source is chlorine, the external chlorine enters the filter box 22 through the inlet pipe 26. At this time, the filter plate 24 can filter out fine impurities in the chlorine to ensure the cleanliness of the gas. The desiccant inside the drying box 25 can remove moisture from the chlorine to keep the gas dry. When the first valve 211 is opened, the purified chlorine enters the reactor 1 to start the reaction.

[0026] A motor 5 is installed at the top of the first cover 23. A rotating rod 51 is fixedly connected to the output end of the motor 5, and a scraper 511 is fixedly connected to the bottom end of the rotating rod 51. The bottom end of the scraper 511 contacts the top end of the filter plate 24. The rotating rod 51 rotates through the first cover 23. The motor 5 drives the rotating rod 51 to rotate. As the rotating rod 51 rotates, the scraper 511 moves along the top end of the filter plate 24. At this time, the scraper 511 cleans the impurities on the top end of the filter plate 24 through mechanical movement, preventing the accumulation of particulate matter from reducing the filtration efficiency of the filter plate 24.

[0027] A mounting base 512 is fixedly connected to the outer surface of the rotating rod 51. The mounting base 512 is positioned above the scraper 511, and a fan blade 5121 is fixedly connected to the outer surface of the mounting base 512. When the rotating rod 51 rotates, it drives the mounting base 512 to rotate, which in turn drives the fan blade 5121 to rotate. The rotation of the fan blade 5121 helps to accelerate the passage of chlorine gas through the filter box 22, thereby improving the overall gas flow speed and efficiency.

[0028] A sealing cap 11 is movably connected to the top of reactor 1, and a discharge port 13 is fixedly connected to the bottom of reactor 1. A second valve 131 is fixedly connected to the outer surface of the discharge port 13. By opening the sealing cap 11, it is convenient to add materials such as tantalum powder into reactor 1. The combination of the discharge port 13 and the second valve 131 allows reactor 1 to conveniently discharge the reaction products after the reaction is completed.

[0029] A vacuum pump 7 is installed on one side of reactor 1. One end of the vacuum pump 7 is fixedly connected to a suction pipe 4, and a third valve 41 is fixedly connected to the outer surface of the suction pipe 4. One end of the suction pipe 4 is connected to reactor 1. The vacuum pump 7 is used to extract gas from inside reactor 1 to create a vacuum environment. When the vacuum pump 7 is started and the third valve 41 is opened, air is extracted from inside reactor 1 through the suction pipe 4, which facilitates a rapid reduction in the gas pressure inside reactor 1 to achieve the required vacuum level.

[0030] A heating pipe is installed in the jacket of reactor 1, and a support leg 12 is fixedly connected to the bottom of reactor 1. A support block 121 is fixedly connected to the bottom of the support leg 12. The support leg 12 and the support block 121 facilitate the support and fixation of reactor 1. The heating pipe is used to provide heat to maintain or regulate the internal temperature of reactor 1, ensuring the temperature consistency and stability of the reaction environment.

[0031] A purification chamber 3 is installed on one side of reactor 1. A second cover 31 is movably connected to the top of the purification chamber 3. An air pump 6 is installed on the top of the second cover 31. One end of the air pump 6 is fixedly connected to a first gas pipe 61, and the other end is fixedly connected to a second gas pipe 62. The first gas pipe 61 is fixedly connected to the second cover 31, and the second gas pipe 62 is fixedly connected to reactor 1. The purification chamber 3 is used to treat the waste gas after the reaction. Sodium hydroxide solution is placed inside the purification chamber 3. When the air pump 6 is started, the chlorine gas remaining in reactor 1 after the reaction enters the purification chamber 3 through the second gas pipe 62 and the first gas pipe 61. Inside the purification chamber 3, the chlorine gas reacts chemically with the sodium hydroxide solution to generate harmless byproducts, thereby preventing harmful gases from being directly emitted into the environment and protecting the environment.

[0032] A drain pipe 32 is fixedly connected to the outer surface of the purification tank 3, and a fourth valve 321 is fixedly connected to the outer surface of the drain pipe 32. Opening the fourth valve 321 facilitates the discharge of liquid inside the purification tank 3, thereby facilitating the periodic replacement of sodium hydroxide solution or cleaning.

[0033] In operation, tantalum metal powder is first placed into reactor 1, and necessary preparations are made, such as an airtightness check. Then, vacuum pump 7 is started and the third valve 41 is opened to extract air from reactor 1 through the extraction pipe 4, which facilitates a rapid reduction in the gas pressure inside reactor 1 to achieve the required vacuum level. The heating tube is used to provide heat to maintain or regulate the temperature inside reactor 1, ensuring the temperature consistency and stability of the reaction environment. External chlorine gas enters the filter box 22 through the inlet pipe 26. At this time, the filter plate 24 facilitates the filtration of fine impurities in the chlorine gas, ensuring the cleanliness of the gas. The desiccant inside the drying box 25 facilitates the removal of moisture from the chlorine gas to keep the gas dry. The motor 5 drives the rotating rod 51 to rotate. As the rotating rod 51 rotates, the scraper 511 moves along... The top of the filter plate 24 moves to prevent particulate matter from accumulating and reducing the filtration efficiency of the filter plate 24. The rotating rod 51 rotates while driving the mounting base 512 to rotate. The rotation of the mounting base 512 drives the fan blade 5121 to rotate. The rotation of the fan blade 5121 helps to accelerate the passage of chlorine gas through the filter box 22, improving the overall gas flow speed and efficiency. The first valve 211 is opened, and the purified chlorine gas enters the reactor 1 to start the reaction. After the reaction is completed, the vacuum pump 6 is started. Under the action of the vacuum pump 6, the remaining chlorine gas in the reactor 1 after the reaction enters the purification box 3 through the second gas pipe 62 and the first gas pipe 61. In the purification box 3, the chlorine gas reacts chemically with the sodium hydroxide solution to generate harmless byproducts, thereby avoiding the direct emission of harmful gases into the environment and protecting the environment.

[0034] This carefully designed air intake assembly not only ensures the purity and freedom of impurities in the chlorine gas entering the reactor but also maintains the gas's dryness, thereby significantly improving the quality and stability of the coating. This is particularly important for the preparation of high-performance biocompatible materials, contributing to more reliable and safer medical implants and other bioengineering applications.

[0035] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
