Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a flexible tube. Background Technology

[0002] In the medical field, joint cavity irrigation technology is widely used in the treatment of various joint diseases, such as arthritis, joint injuries, and postoperative joint debridement. Currently, various devices and materials are available for joint cavity irrigation to remove pathological substances, reduce the risk of infection, and promote healing. However, existing irrigation hoses still have some shortcomings in structure and function. First, the inlet and outlet structures of existing irrigation hoses often cannot effectively control the flow and distribution of the fluid, resulting in uneven irrigation within the joint cavity and difficulty in achieving optimal cleaning results. Second, the diameter and area of ​​the inlet and outlet orifices of some hoses are insufficient, which may restrict the flow of fluid and easily cause fluid stagnation. Furthermore, the internal structure of existing hoses often lacks necessary partitions, which exacerbates the mixing between the inlet and outlet fluids, further reducing the irrigation effect. Therefore, a new hose design is needed to solve the above problems and improve the effectiveness of joint cavity irrigation. This hose needs to have a reasonable layout of inlet and outlet orifices, and a suitable partition design to ensure effective fluid flow and cleaning, thereby achieving comprehensive cleaning and disinfection of the joint cavity. Utility Model Content

[0003] This utility model aims to solve at least one of the above-mentioned technical problems.

[0004] To solve the above problems, the primary objective of this utility model is to provide a flexible hose, comprising: an inlet section having a plurality of inlet holes; and an outlet section connected to the inlet section.

[0005] The inlet section features multiple inlet holes, helping to ensure even distribution of the fluid within the section, thereby improving the effectiveness of the flushing and ensuring smooth entry and coverage of the target area. The flexible tubing design minimizes mechanical damage to the joint cavity tissues during cleaning, protecting the joint structure. Its flexible design allows it to adapt to different joint shapes and positions, facilitating surgical manipulation. By adjusting the fluid flow rate in the inlet section, the cleaning intensity can be adjusted to meet the needs of different patients. The integrated design allows surgeons to perform joint cavity cleaning more conveniently during surgery, reducing reliance on other equipment.

[0006] In the above technical solution, a partition is provided between the liquid inlet section and the liquid outlet section.

[0007] The partition helps regulate the flow of liquid between the inlet and outlet sections, ensuring that the cleaning liquid is evenly distributed throughout the joint cavity and preventing localized over-cleaning or insufficient liquid. The partition design creates a pressure difference between the inlet and outlet, enhancing liquid circulation within the joint cavity and improving cleaning efficiency. The partition prevents the cleaning liquid from contaminating with other waste during backflow, maintaining the cleanliness and quality of the outlet liquid and providing better cleaning results. Integrating the partition into a single hose simplifies the equipment's structural design, reduces additional connectors and components, and improves overall usability and reliability. The partition also serves as an important safety mechanism, ensuring that the inlet and outlet systems do not interfere with each other due to unforeseen circumstances during operation, thus enhancing safety during use.

[0008] In any of the above technical solutions, the liquid outlet section is provided with several liquid outlet holes.

[0009] Multiple outlets increase the drainage rate of the fluid, reduce fluid retention during the cleaning process, and ensure a more thorough cleaning. Multiple outlets also allow for more even distribution of the drained fluid, preventing excessive local pressure caused by fluid concentration at the outlet, thus resulting in a more uniform cleaning effect. The variety and distribution of outlets allow for wider coverage of the cleaning fluid within the joint cavity, effectively removing impurities and waste from various areas. Because of the multiple outlets, even if one outlet is blocked, the others can still drain normally, reducing the risk of the entire system being affected by blockage of a single outlet. The design of multiple outlets reduces the overall pressure in the drainage section, minimizing impact on tissues during cleaning and reducing the risk of postoperative complications.

[0010] In any of the above technical solutions, the total area of ​​the several liquid outlet holes is greater than the cross-sectional area of ​​the liquid outlet section.

[0011] When the total area of ​​the outlet holes is greater than the cross-sectional area of ​​the outlet section, this design allows for faster liquid discharge compared to existing technologies where only the pipe cross-section can discharge. This design significantly increases the liquid outflow velocity, reduces residence time during the cleaning process, and improves cleaning efficiency. Enlarging the total area of ​​the outlet holes effectively reduces the risk of liquid stagnation within the outlet section, thereby reducing the chance of bacterial growth or contamination during cleaning and improving the system's hygiene and safety. While the cross-sectional area of ​​the outlet section limits the liquid outflow velocity, increasing the outlet hole area balances pressure, reduces pressure loss within the outlet section, ensures smooth liquid flow, and further improves drainage efficiency.

[0012] In any of the above technical solutions, the total area of ​​the several liquid outlet holes is greater than the total area of ​​the several liquid inlet holes.

[0013] A larger outlet area than an inlet area promotes efficient fluid drainage within the system. This means more fluid can be drained within a given timeframe, reducing fluid retention and improving overall cleaning effectiveness. The larger outlet area allows for rapid fluid drainage even at high flow rates, effectively preventing backflow and ensuring thorough circulation of the cleaning fluid within the joint cavity. The larger total outlet area also reduces internal system pressure, mitigating impact on tissues. This lower pressure helps protect delicate biological tissues during cleaning, minimizing potential damage or discomfort. The larger outlet area also reduces the risk of blockage due to uneven flow rates or viscous fluids. Even if some outlets are partially blocked, overall drainage remains effective. Furthermore, a larger outlet area prevents fluid retention within the joint cavity, avoiding excessive pressure and potential damage.

[0014] In any of the above technical solutions, the total area of ​​the several inlet holes is greater than the cross-sectional area of ​​the inlet section.

[0015] The total area of ​​the inlet orifices is larger than the cross-sectional area of ​​the inlet section, which promotes rapid liquid inflow. This means that more cleaning liquid can be introduced within a specific time, improving the system's cleaning efficiency. A larger inlet orifice area reduces the flow resistance encountered by the liquid as it enters the inlet section, effectively reducing pressure drop and preventing stagnation that could lead to poor cleaning. Multiple inlet orifices ensure a more uniform distribution of cleaning liquid as it enters the joint cavity or system, avoiding cleaning dead zones caused by uneven flow and improving overall cleaning effectiveness. Due to the increased inlet orifice area, the system can introduce cleaning liquid at a higher throughput, ensuring sufficient liquid flow during cleaning to achieve the desired cleaning effect. The increased inlet orifice area also improves the system's adaptability to liquids of different viscosities, enabling smoother flow for high-viscosity fluids and enhancing the system's versatility.

[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; however, this utility model can also be implemented in other ways different from those described herein. Therefore, the scope of protection of this utility model is not limited to the specific embodiments disclosed below.

[0023] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, an embodiment of this utility model provides a flexible hose, comprising: an inlet section 100 having a plurality of inlet holes 110; and an outlet section 200 connected to the inlet section 100, having a plurality of outlet holes 210; wherein a partition 300 is provided between the inlet section 100 and the outlet section 200; the total area of ​​the plurality of outlet holes 210 is greater than the cross-sectional area of ​​the outlet section 200; the total area of ​​the plurality of outlet holes 210 is greater than the total area of ​​the plurality of inlet holes 110; and the total area of ​​the plurality of inlet holes 110 is greater than the cross-sectional area of ​​the inlet section 100.

[0024] In this embodiment, the inlet section 100 and the outlet section 200 are separated by a partition 300 to prevent the cleaning fluid from directly flowing from the inlet section 100 into the outlet section 200, which would result in poor cleaning performance. In existing technologies, typically only one inlet or outlet with a circular cross-section is provided. In this embodiment, by providing several inlet holes 110 and several outlet holes 210, with the total area of ​​the inlet holes 110 exceeding the cross-sectional area of ​​the inlet section 100 and the total area of ​​the outlet holes 210 exceeding the cross-sectional area of ​​the outlet section 200, the efficiency of inlet and outlet is significantly higher than in existing technologies, thereby improving the efficiency of cleaning the joint cavity. The total area of ​​the outlet holes 210 is greater than the total area of ​​the inlet holes 110, ensuring that the outlet capacity is greater than the inlet capacity, preventing the inlet volume from exceeding the outlet volume, which could lead to continuous compression of the fluid inside the joint cavity and cause damage. During joint cavity cleaning, a suitable cleaning fluid is injected through the inlet section 100, flows into the joint cavity through the inlet hole 110, and then flows out through the outlet section 200. The fluid in the joint cavity flows into the outlet section 200 through the outlet hole 210 and is then discharged, thus achieving the effect of cleaning the joint cavity. Furthermore, the multiple outlet holes 210 and multiple inlet holes 110 ensure that even if one or more holes become blocked, some holes can still function normally.
