Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, and in particular to an ultrasonic cleaning machine for the production of medical biological dressings. Background Technology

[0002] Medical biological dressings, such as those made from biomaterials like collagen, silicone, alginate, chitosan, or hyaluronic acid, are important products in modern wound care and tissue engineering. These dressings are widely used due to their excellent biocompatibility and ability to promote tissue repair. During their production, to ensure the safety and effectiveness of the product, the dressings must be thoroughly cleaned to remove contaminants such as particulate impurities, chemical residues, microorganisms, and endotoxins that may be introduced during the production process. Since medical biological dressings come into direct contact with human wounds, any residual contaminants may cause infection, allergic reactions, or affect wound healing; therefore, their cleanliness requirements are extremely stringent.

[0003] Ultrasonic cleaning technology is considered an effective means of cleaning precision objects due to its non-contact nature and ability to penetrate into tiny pores. However, in traditional ultrasonic cleaning tanks, contaminants detached from the dressing surface remain suspended in the cleaning solution. As cleaning progresses, the contamination level of the cleaning solution increases, and these suspended contaminants may redeposit on the dressing surface, causing secondary contamination and resulting in poor and unstable cleaning effects. To solve this problem, it is usually necessary to frequently replace expensive medical purified water, which is not only cumbersome to operate but also greatly increases production costs. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning device that can gently and thoroughly remove contaminants while effectively avoiding secondary pollution.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an ultrasonic cleaning machine for the production of medical biological dressings, comprising a housing, a cleaning box fixedly installed at the top opening of the housing, the top of the cleaning box being recessed downward to form a cleaning groove, and a sealing cover installed on the top of the cleaning box; The ultrasonic component installed in the enclosure includes at least one ultrasonic transducer installed on the side wall of the cleaning tank and an ultrasonic generator located at the bottom of the inner cavity of the enclosure, which are connected by a cable. The filter assembly installed in the housing includes a drain pipe, a filter box, a water storage tank, and a water pump connected in sequence. The water pump's inlet pipe extends to the bottom of the water storage tank, and its outlet pipe extends to the top of the cleaning box.

[0006] As a further description of the above technical solution: the cleaning box and the cleaning tank are made of medical-grade 316L stainless steel. The inner surface of the cleaning tank is electrolytically polished to form a mirror smoothness, and its internal corners are rounded transition structures.

[0007] As a further description of the above technical solution: the filter box is provided with a first filter plate and a second filter plate that are spaced apart along the liquid flow direction. The first filter plate is a coarse filter screen and the second filter plate is a fine filter screen. The two are fixedly installed by a flange on the inner wall of the filter box.

[0008] As a further description of the above technical solution: the bottom side wall of the filter box is provided with multiple water supply pipes, each water supply pipe is connected to a replaceable filter cartridge, and the filter cartridge is filled with a microporous filter element.

[0009] As a further description of the above technical solution: the first filter plate, the second filter plate and multiple filter cartridges constitute a three-stage series filtration path, and the number of filter cartridges is 3-6.

[0010] As a further description of the above technical solution: the side wall mounting position of the ultrasonic transducer makes the sound field direction parallel to the bottom surface of the cleaning tank, forming horizontal ultrasonic radiation.

[0011] As a further description of the above technical solution: the cleaning box is fixedly connected to the box body by sealed welding or flange structure, and the drain pipe is connected to the filter box by a quick-release connector.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. During the cleaning process, the cleaning solution containing contaminants is filtered through three stages: the first filter plate, the second filter plate, and the filter cartridge, which completely traps the contaminants. The purified clean liquid is then pumped back to the cleaning tank, ensuring that the biological dressing is always in a high-cleanliness flowing cleaning solution environment. This solves the problem of secondary pollution caused by suspended contaminants in traditional cleaning methods, thereby greatly improving the cleanliness and consistency of the cleaning.

[0013] 2. By using multiple filter cartridges, contaminants are distributed among the cartridges, avoiding the rapid clogging of a single cartridge, extending the service life of each filter media, reducing the cost and waste caused by frequent replacements, and the failure or performance degradation of a single cartridge will not immediately cause the entire filtration assembly to collapse, thus reducing the risk.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 This utility model provides a technical solution: an ultrasonic cleaning machine for the production of medical biological dressings, including a box 10, which serves as the support and housing structure for the entire equipment. A cleaning box 11 is fixedly connected to the top opening of the box 10 by a sealed welding or flange structure. The cleaning box 11 and the box 10 can be an integrated design or fixedly connected by a sealed method to ensure the stability and airtightness of the structure.

[0018] The top of the cleaning box 11 is recessed downwards through one-piece molding or stamping process to form a cleaning tank 111 for containing the items to be cleaned and the cleaning solution. In order to meet the stringent standards of medical grade, the entire cleaning box 11, especially the cleaning tank 111 which is in direct contact with the cleaning solution and medical dressings, is made of high-quality medical-grade stainless steel, such as 316L stainless steel. This material has excellent corrosion resistance and biocompatibility, and can effectively prevent the release of metal ions to contaminate the biological dressings.

[0019] Furthermore, the inner surface of the cleaning tank 111 undergoes electrolytic polishing, a process that achieves a mirror-like smoothness, significantly reducing surface roughness and effectively preventing the adhesion and residue of particles, bacteria, or biofilms generated during production. The internal structure of the cleaning tank 111 is designed with no dead angles, such as rounded corners, completely eliminating areas difficult to clean in traditional right-angle structures. This optimized structural design, combined with its optimized dimensions, facilitates the placement and removal of delicate and fragile biological dressings by operators, while also ensuring that ultrasonic energy can be evenly applied to every surface of the dressing, achieving comprehensive and precise cleaning. To maintain a clean internal environment during cleaning, prevent cleaning fluid evaporation, and reduce noise, the top of the cleaning tank 11 is also equipped with a removable or flip-up sealing cover 12.

[0020] The core cleaning function of this equipment is achieved by an ultrasonic component, which mainly includes at least one ultrasonic transducer 14 installed on the side wall of the cleaning tank 111 and an ultrasonic generator 15 installed at the bottom of the inner cavity of the housing 10. The ultrasonic generator 15 converts the input power frequency AC power into a high-frequency, high-voltage electrical signal. This electrical signal is stably transmitted through a cable and connected to the ultrasonic transducer 14. The piezoelectric ceramic element inside the ultrasonic transducer 14 generates high-frequency mechanical vibration under the excitation of the high-frequency electrical signal, and introduces this vibration into the cleaning fluid in the cleaning tank 111, triggering a cavitation effect, thereby performing efficient, non-contact micro-cleaning of biological dressings. Arranging the ultrasonic transducer 14 on the side wall helps to form a horizontal sound field in the tank, providing a more uniform cleaning effect for suspended or lightweight dressings.

[0021] To ensure the purity of the cleaning solution throughout the cleaning process, this equipment integrates a set of high-efficiency circulating filtration components. A drain pipe 112 is provided at the bottom of the cleaning tank 11. The used cleaning solution containing impurities in the cleaning tank 111 flows out through this pipe under gravity and is transported to the filtration components.

[0022] The filtration assembly includes a filter box 17, and a drain pipe 112 is connected to the filter box 17 by a quick-release connector. In the inner cavity of the filter box 17, along the liquid flow path, at least two flanges for staged filtration are provided, which are used to place the first filter plate 18 and the second filter plate 19, respectively. The first filter plate 18 is designed as a coarse filter screen with a larger pore size to intercept larger particulate impurities; the second filter plate 19 is a fine filter screen with a smaller pore size to filter finer suspended matter. After two stages of plate filtration, the liquid collects at the bottom of the filter box 17.

[0023] Several water supply pipes 171 are evenly distributed on the side wall at the bottom of the filter box 17. Each water supply pipe 171 is connected to a replaceable filter cartridge 20. The filter cartridge 20 serves as the third-stage fine filtration unit and can be filled with high-precision filter materials such as microporous filter elements to ultimately capture micron-sized pollutants and ensure the cleanliness of the outflowing liquid. This multi-stage series filtration design not only improves filtration efficiency and accuracy but also extends the service life of each stage of filter media.

[0024] The bottom of the filter assembly is equipped with a water tank 16 for collecting and storing the clean cleaning solution after three-stage filtration.

[0025] In order to achieve the recycling of cleaning fluid, a water pump 21 is also installed in the inner cavity of the tank 10. The water inlet pipe 22 of the water pump 21 extends to the bottom of the inner cavity of the water storage tank 16 to ensure that the stored clean liquid can be effectively extracted. The water outlet pipe 13 of the water pump 21 extends upward, and its outlet is located at the top of the cleaning tank 11.

[0026] When using this equipment, first place the medical biological dressing to be cleaned in the cleaning tank 111 and inject an appropriate amount of cleaning solution, such as medical purified water. After covering with the sealing cap 12, start the equipment. The ultrasonic generator 15 drives the ultrasonic transducer 14 to work, performing ultrasonic cleaning on the dressing. At the same time, the water pump 21 starts, initiating the liquid circulation filtration process. The cleaning solution containing contaminants detached from the dressing surface flows out from the drain pipe 112 at the bottom of the cleaning tank 111 and enters the filter box 17 in sequence. After passing through the first filter plate 18, the second filter plate 19, and the filter cylinder 20, the contaminants are effectively trapped. The purified cleaning solution flows into the water storage tank 16 and is then pumped out by the water pump 21 through the inlet pipe 22, and then pumped back to the top of the cleaning tank 111 through the outlet pipe 13. This forms a closed-loop circulation, ensuring that the cleaning solution in the cleaning tank 111 always maintains a high level of cleanliness, greatly improving the cleaning quality and efficiency, while also saving water resources.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
