[0002] According to statistics, more than 75% of hydraulic system failures are caused by oil contamination. Particles in the hydraulic oil will wear the surface of hydraulic components, and oil leakage may block the channels, thus affecting the reliability of the entire hydraulic system, and even causing equipment damage and threatening personal safety. Whether in terms of technology or economic benefits, ensuring the cleanliness of hydraulic oil is crucial for hydraulic systems.

[0003] In the related art, for equipment without a filtration system, the oil pollution problem is usually solved by manually replacing the oil, which has high labor costs and causes oil waste. Of course, some operating table hydraulic systems can also use external equipment to clean the oil, but this method is not thorough, and the hydraulic components are prone to aging after the equipment continues to work, and replacing the hydraulic components or the oil source will have the risk of re-contamination.

[0023] Example:

[0024] like Figure 1-3 As shown, in this embodiment, the implantable filtering device is used in a hydraulic system 1, and the implantable filtering device includes a pipeline assembly and an oil tank 2 for containing oil. A first circulation channel a and a second circulation channel b are arranged between the oil tank 2 and the pipeline assembly. The first circulation channel a passes through the hydraulic system 1, and the second circulation channel b does not pass through the hydraulic system 1; the first circulation channel a and the second circulation channel b have overlapping main oil circuits; the pipeline assembly includes a valve 3 and a filter 4 installed on the main oil circuit; the valve 3 is used to allow the oil to circulate in the first circulation channel a or the second circulation channel b.

[0025] Specifically, the hydraulic system 1 of this embodiment can be the hydraulic system of an operating table. In this embodiment, a filter device is directly integrated on the hydraulic system 1, so that a clean circulation pipeline with a filter 4 is formed between the hydraulic system 1 and the implantable filter device, so that the oil (crude oil) stored in the oil tank 2 and the used oil can be self-circulated and filtered, with high cleaning efficiency, which is beneficial to extending the service life of the hydraulic components in the hydraulic system 1, improving the reliability of the operating table equipment, improving the working efficiency of the operating table, and reducing the cost of equipment use; and there is no need to manually replace the oil, which is beneficial to reducing labor costs and avoiding oil waste.

[0026] In this embodiment, the oil tank 2 can be a system oil tank of the hydraulic system 1. The oil tank 2 can provide oil to the hydraulic system 1 and receive the oil flowing back from the hydraulic system 1, and can also precipitate oil impurities that are not easy to circulate. The main oil circuit includes a liquid outlet section c and a return section d respectively connected to the oil tank 2, and an oil pump 5 is also installed on the liquid outlet section c. The oil pump 5 provides power for the circulation of the oil, so that the oil in the oil tank 2 can flow out from the liquid outlet section c, flow through the first circulation channel a or the second circulation channel b, and be filtered in the filter 4, and finally flow back to the oil tank 2 through the return section d.

[0027] Furthermore, in this embodiment, a filter screen 6 is provided between the oil pump 5 and the oil tank 2. The filter screen 6, the gap of which can be larger than the filter 4, can be used to perform simple coarse filtration on the oil, first filter out relatively large particles, and improve the efficiency of cleaning the circulation pipeline. In this embodiment, the filter 4 can be a high-pressure filter or a low-pressure filter, and can also be a magnetic filter, which can have a water absorption function. The above-mentioned filter 4 can be used to finely filter the oil, filter out fine particles in the operating bed system, and reduce the risk of wear and aging of hydraulic components.

[0028] In this embodiment, by adjusting the valve 3, the oil can be circulated through the hydraulic system 1 when the operating bed hydraulic system 1 is working and filtered and cleaned by the filter 4, and the oil can also be directly circulated and filtered without passing through the hydraulic system 1 when the operating bed hydraulic system 1 is not working. The valve 3 can be one of a ball valve, a one-way valve, a solenoid valve, and a sequence valve, which is not limited here. Preferably, the valve 3 of this embodiment can be a ball valve, specifically a two-position two-way on-off valve, which can realize active opening and closing and has high working efficiency.

[0029] like Figure 3As shown, in this embodiment, the ball valve is fixedly connected to the filter 4, that is, the ball valve and the filter 4 can be directly integrated into a filter valve, which has a compact structure and beautiful appearance. Of course, in some embodiments, the ball valve and the filter 4 can also be connected by a pipeline, which is not limited here. In this embodiment, an overflow valve 7 for maintaining a stable pressure in the pipe is also installed between the liquid outlet section c and the reflux section d. The overflow valve 7 can be used as a safety valve. When the system is affected by the load or the hydraulic system 1 is blocked and the pressure in the pipe increases (when the pressure in the pipe is higher than the set value of the overflow valve 7), the oil can flow directly back to the oil tank 2 after the overflow valve 7 and the reflux section d, ensuring the pressure problem of the pipeline assembly and ensuring the safety and working stability of the implantable filtering device.

[0030] like Figure 1 As shown, in the first implementation of this embodiment, the filter 4 can be connected between the oil pump 5 and the hydraulic system 1, so that the pipeline is controlled by branching after passing through the filter 4. When in use, the oil pump 5 is started, so that the oil in the oil tank 2 is primarily filtered through the filter 6, and then enters the filter 4 through the oil pump 5; if the operating bed hydraulic system 1 is not working at this time and the ball valve is reversed, the branch oil circuits before and after the ball valve are connected, and the oil passes through the ball valve and then returns to the oil tank 2, thereby realizing self-circulation filtration of the oil in the oil tank 2; if the operating bed hydraulic system 1 is working at this time and the ball valve is not reversed, the oil will enter the operating bed hydraulic system 1 after being filtered by the filter 4, and finally return to the oil tank 2 through the pipeline, thereby realizing circulation filtration of the operating bed hydraulic system 1.

[0031] like Figure 2 As shown, in the second implementation of this embodiment, the filter 4 is arranged on the reflux section d, that is, when in use, the oil flows out of the oil pump 5, passes through the valve 3 or the hydraulic system 1, and then reaches the filter 4, and then returns to the oil tank 2 through the pipeline after being filtered by the filter 4. When in use, the oil pump 5 is started, so that the oil in the oil tank 2 is primary filtered through the filter 6, and then passes through the oil pump 5; if the operating bed hydraulic system 1 is not working at this time and the ball valve is reversed, the branch oil circuits before and after the ball valve are connected, and the oil passes through the ball valve and the filter 4 in turn and finally returns to the oil tank 2, thereby realizing the self-circulation filtration of the oil in the oil tank 2; if the operating bed hydraulic system 1 is working at this time and the ball valve is not reversed, the oil will enter the operating bed hydraulic system 1 after passing through the oil pump 5, then flow through the filter 4, and finally return to the oil tank 2 through the pipeline, thereby realizing the circulation filtration of the operating bed hydraulic system 1.

[0032] The filtration system of this embodiment can be a filtration system for an operating bed. The filtration system includes a hydraulic system 1 and an implantable filtration device. The implantable filtration device is integrated into the operating bed system, and the oil in the system can be cleaned without the use of additional external equipment; that is, the hydraulic system 1 and the implantable filtration device are connected to form a clean circulation pipeline for the oil, and the clean circulation pipeline includes a first circulation channel a and a second circulation channel b. The pipeline settings of the two circulation channels can switch to control the oil to perform self-circulation filtration and clean filtration of the operating bed hydraulic system 1, thereby ensuring the cleanliness of the hydraulic oil.

[0033] It is understandable that the use scope of the filtration system of this embodiment is not limited to the operating table of medical equipment, but can also be used in other application scenarios. For example, in some other embodiments, the implantable filtration device can also be used in mechanical hydraulic systems, hydraulic systems in the chemical field, etc., which are not limited here.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
