Description

Technical Field

[0001] This invention relates to the field of fluid control components and integrated systems, specifically to a pipeline direct-connect multi-way valve and a medical valve island. Background Technology

[0002] Medical valve islands are modular pneumatic control systems used in medical equipment, primarily for precise control of gas or liquid flow, and are widely used in medical devices such as ventilators, anesthesia machines, and dispensing machines. Existing medical valve islands have the following drawbacks: poor integration, cumbersome assembly, and high leakage risk: Existing valve islands require numerous external pipe connections to multiple independent multi-port valves, resulting in a large number of pipe interfaces (typically 16-20 interfaces for an 8-channel valve island). This not only makes the assembly process cumbersome (assembly time approximately 4-6 hours), but also makes the interfaces prone to leakage due to poor sealing, especially in reagent and sample transport scenarios, where leakage can lead to cross-contamination. Inadequate housing design and high maintenance difficulty: Existing valve island housings are mostly "integral structures," requiring disassembly of the entire housing to access the internal valve body during maintenance, making the operation complex; furthermore, the housings are mostly made of plastic, lacking structural strength, making them susceptible to impact damage during medical equipment handling and daily operation, affecting the stability of internal components. Poor compatibility and scalability: The valve bodies and interfaces of existing valve islands are mostly fixed matching designs. If it is necessary to add fluid channels (such as expanding from 4 channels to 8 channels), the valve island shell and connection structure need to be redesigned, which cannot flexibly adapt to the functional upgrade needs of medical equipment. At the same time, the interface is not standardized, making it difficult to be compatible with medical fluid accessories from different brands (such as Luer connectors and quick-connect connectors). Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide a pipeline direct-connection multi-way valve, which has the advantages of stable structure, convenient disassembly and assembly, and low cost.

[0004] The technical solution adopted in this invention is: a pipeline direct-connection multi-way valve, including a valve body, a valve cavity provided in the valve body; valve connectors communicating with the valve cavity are provided on the outer side and upper end of the valve body; symmetrically arranged mounting parts are provided on the lower outer side of the valve body, and insert nuts are embedded in the mounting parts; a number of reinforcing ribs are provided on the outer periphery of the valve body at intervals along the transverse or longitudinal direction of the valve body, and the transversely arranged reinforcing ribs are arranged at intervals along the upper and lower sides of the valve body.

[0005] In this technical solution, the valve body adopts a modular structure, which reduces development costs and development cycle. The valve body is connected to other structures through valve joints. During installation, the valve body is fixed in the installation position by the mounting part. Since the mounting part is equipped with insert nuts, the convenience of installation and disassembly can be improved, making it easier to carry out maintenance on the equipment with the valve body installed and reducing maintenance costs. The surface of the valve body has a reinforcing rib structure to ensure the overall strength of the valve body.

[0006] Preferably, the lower end of the valve body is provided with an installation port, and the edge of the installation port is provided with a disassembly notch.

[0007] Preferably, the valve connector is provided with a detachable replaceable insert for opening and closing the valve connector.

[0008] Preferably, the valve body is formed using an injection molding process.

[0009] The present invention also provides a medical valve island that uses the aforementioned direct-connect multi-way valve, which can reduce the cost of use and maintenance. Specifically, it includes a valve island shell, which has an installation space for installing several valve bodies inside. The top of the valve island shell is provided with an external conversion joint, which is connected to the valve joint of the valve body through a connecting pipe.

[0010] Preferably, the valve island housing is further provided with an internal conversion joint for connecting adjacent valve bodies, and the internal conversion joint is provided with a connecting pipe for connecting to the valve connector.

[0011] Preferably, the valve island housing has horizontally outwardly extending mounting plates on both sides of its lower end.

[0012] Preferably, the valve island housing is provided with fixing parts corresponding to the mounting portions on both sides of the bottom of the valve body.

[0013] Preferably, the valve island housing comprises multiple sheet metal housings, with connecting portions between adjacent sheet metal housings and connecting parts on the connecting portions.

[0014] The beneficial effects of this invention are as follows: The valve body provided by this invention can add replaceable inserts to each passage during mold development according to actual needs. By replacing the replaceable inserts, a valve body with two states—open and closed—can be produced. It can be selected according to functional needs, reducing development costs and shortening the development cycle. The valve body mounting part uses embedded nuts to ensure the strength and reliability of the installation. The valve body adopts injection molding process, which directly reduces module costs and ensures the consistency of product precision. It has high practical value. Attached Figure Description

Detailed Implementation

[0019] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0020] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by those skilled in the art to which this invention pertains.

[0021] Example 1

[0022] like Figure 1 As shown in the figure, a specific embodiment of the present invention provides a pipeline direct-connection multi-way valve, including a valve body 100, a valve cavity 110 inside the valve body 100; a valve connector 120 communicating with the valve cavity 110 is provided on the outer side and upper end of the valve body 100; a symmetrically arranged mounting part 130 is provided on the lower outer side of the valve body 100, and an insert nut 131 is embedded in the mounting part 130; a plurality of reinforcing ribs 140 are provided on the outer periphery of the valve body 100 at intervals along the transverse or longitudinal direction of the valve body 100, and the transversely arranged reinforcing ribs 140 are arranged at intervals along the vertical direction of the valve body 100.

[0023] like Figure 1As shown, through the above settings, the valve body 100 in this embodiment adopts a modular structure, which reduces development costs and development cycle. The core valve cavity 110 and valve connector 120 can be flexibly configured according to the needs of medical equipment (such as adjusting the number of valve connectors 120 according to the number of fluid passages, and adjusting the specifications of valve connectors 120 according to the interface type), without the need to redesign the overall mold. The valve body 100 is connected to other structures via the valve connector 120. During installation, the valve body 100 is fixed in its mounting position via the mounting part 130. Since the mounting part 130 is equipped with an insert nut 131, it is directly fixed by bolts engaging with the insert nut 131 during installation, eliminating the need for external nuts on-site. This ensures the strength and reliability of the valve body 100's installation and fixation. Simultaneously, there is no risk of nut stripping or loss during disassembly and maintenance, ensuring the continuous availability of the medical equipment. The valve body 100 surface has a reinforcing rib structure 140. The valve body 100 has transverse and longitudinal reinforcing ribs 140 on its outer periphery: the transverse reinforcing ribs 140 are spaced vertically along the valve body 100, enhancing its resistance to deformation in the vertical direction; the longitudinal reinforcing ribs 140 are distributed circumferentially along the valve body 100, improving its overall rigidity. These two structures work together to resist pressure fluctuations during medical fluid delivery, effectively ensuring the sealing performance of the valve cavity 110 and preventing fluid leakage.

[0024] like Figure 1 As shown, the valve body 100 has an installation port at its lower end, with a disassembly notch 150 at the edge of the installation port. The installation port and disassembly notch 150 facilitate installation and fixation, and improve installation positioning accuracy. Simultaneously, the valve connector has a detachable replaceable insert for opening and closing the valve connector. By replacing the replaceable insert, the valve body can be configured to have both open and closed states for the three valve connectors. The valve body 100 is injection molded, directly reducing module costs and ensuring consistent product precision. The disassembly notch 150 at the lower end of the valve body 100's installation port edge can precisely mate with the positioning protrusion of the valve island shell 200, keeping assembly positioning errors within a minimal range and preventing misalignment between the valve connector 120 and the pipeline, significantly improving the integration efficiency of the medical valve island.

[0025] Example 2

[0026] like Figure 2 As shown, this embodiment provides a medical valve island for a direct-connected multi-way valve as described in Embodiment 1, including a valve island housing 200. The valve island housing 200 has an installation space 210 for installing a plurality of valve bodies 100. An external conversion connector 300 is provided on the top of the valve island housing 200. The external conversion connector 300 is connected to the valve connector 120 of the valve body 100 through a connecting pipe 400.

[0027] like Figure 2As shown, in this embodiment, the valve island housing 200 is provided with a dedicated installation space 210, which can accommodate several valve bodies 100. The conversion connector is designed to correspond with the valve body 100 to realize the connection between the valve body 100 and the external fluid channel. At the same time, adjacent valve bodies 100 are directly connected through the conversion connector to reduce the risk of fluid leakage.

[0028] like Figure 2 As shown, the valve island housing 200 also includes an internal conversion connector 500 connecting adjacent valve bodies 100. The internal conversion connector 500 has a connecting pipe that connects to the valve connector 120. The conversion connector adopts a standardized design, enabling precise matching with the valve body 100 and valve connector 120 without the need for additional adapters. If the fluid channel needs to be expanded, only an additional valve body 100 and corresponding conversion connector need to be added within the installation space 210 of the valve island housing 200, meeting the functional upgrade requirements of medical equipment. The illustration shows a combination of a four-valve and a seven-valve valve island, with 11 reserved valve body installation positions. If more positions are needed, the housing needs to be replaced and redesigned. If the gas path needs to be changed, only the internal valve bodies and pipeline connections need to be reassembled.

[0029] like Figure 2 As shown, mounting plates 220 extending horizontally outward are provided on both sides of the lower end of the valve island housing 200. The mounting plates 220 at the lower end of the housing can fix the entire valve island onto the medical device mounting frame, achieving horizontal positioning. Fixing members are provided inside the valve island housing 200 corresponding to the mounting portions 130 on both sides of the bottom of the valve body 100. These further secure the valve body 100 and prevent vibration.

[0030] like Figure 2 As shown, the valve island housing 200 comprises multiple sheet metal housings 230, with connecting portions between adjacent sheet metal housings 230 and connecting parts attached to these portions. The valve island housing 200 is constructed from multiple sheet metal housings 230 joined together, achieving a detachable connection through the connecting portions and connecting parts: during maintenance, only the corresponding area of ​​the sheet metal housing 230 needs to be disassembled, eliminating the need for complete disassembly; simultaneously, the tensile strength of the sheet metal housings 230 is ≥200MPa, capable of withstanding impacts during the handling of medical equipment, protecting the internal valve body 100 and pipelines. In the after-sales phase, the failed multi-way valve structure can be directly replaced without replacing the entire structure, reducing maintenance costs.

[0031] The aforementioned medical valve island, through targeted structural innovation, not only solves the core defects of existing multi-way valves and medical valve islands, but also fully meets the medical scenario's requirements for low cost, high stability, easy maintenance, and high precision, demonstrating significant technological progress and practical value.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
