Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a quick interface component between a centralized concentrated liquid supply system for hemodialysis and a hemodialysis machine terminal. Background Art

[0002] With the development of domestic medical technology, centralized liquid supply technology and equipment have been widely used in the field of hemodialysis. Subsequently, various types of centralized liquid supply machine-end interfaces have also been widely used, mainly in the following ways: 1. Clamp-closed type, which refers to the A and B concentrated liquid pipes of the centralized liquid supply system and the concentrated liquid suction pipes at the machine end being directly connected by a three-way joint, and then clamped by two sets of Robert fixed clamps in the normal liquid supply state and the cleaning and disinfection state, respectively, to achieve the normal liquid supply and cleaning and disinfection functions. 2. Fixed interface type, the entire set of interfaces can be composed of a set of interface components, which are fixed to the side of the machine after being connected to the centralized liquid supply pipe. The machine port is connected to the concentrated liquid pipeline. When using centralized liquid supply, the interface is connected to the port on the side of the machine in a plug-in manner. During cleaning and disinfection, the centralized liquid supply interface is disconnected and restored to the original concentrated liquid pipeline of the machine.

[0003] Both of the above methods can fully achieve switching between different states (different usage functions), but the first method requires manual confirmation of the machine status and clamping of the corresponding pipelines, which is prone to errors and disinfection risks. The second method has a large connecting pipe diameter, which is bulky and prone to leakage during actual use, causing serious corrosion and damage to the hemodialysis machine itself, making disinfection inconvenient and prone to waste. In addition, the existing centralized liquid supply machine end interface and machine components are not easy to install and disassemble, affecting machine movement and maintenance; the pipeline design is unreasonable, with "dead space" that easily breeds bacteria or has poor antibacterial effect.

[0026] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0027] As shown Figure 1-6 in the figure, this embodiment provides a quick interface component for a centralized concentrated solution supply system for hemodialysis and a hemodialysis machine terminal, simply referred to as a quick interface component, which includes a bracket 1, a quick connector 2, a Y-shaped connector 3, and a fixing clip 4. The bracket 1 is made of plastic steel. When installed on the saline rod, the shape of the bracket 1 looks like a "冂" character without a "hook" or a "凹" character without a "bottom horizontal bar" from a top view, forming a semi-surrounding structure. The quick connector 2 and the Y-shaped connector 3 are respectively arranged on both sides of the bracket 1. Among them, the Y-shaped connector 3 is located inside the semi-surrounding structure of the bracket 1. The quick connector 2 is used to connect with the centralized liquid supply pipe of the hemodialysis machine terminal. The Y-shaped connector 3 includes a tail end head 31 and two head end heads 32 distributed in a Y shape. One end of the tail end head 31 is connected to the quick connector 2, and the other end of the tail end head 31 is connected to the two head end heads 32. Multi-stage cones 321 are respectively arranged on the outer surfaces of the two head end heads 32 for plug-in connection with A and B concentrated solution pipelines. The fixing clip 4 is arranged on the third side of the bracket 1 for quick connection with the saline rod.

[0028] For the quick interface component provided in this embodiment, the entire quick interface component is based on the bracket 1, and the other components are directly or indirectly installed on the bracket 1, thus forming a whole; moreover, a fixing clip 4 is arranged on the side of the bracket 1; the integrated design and the supporting use of the fixing clip 4 make the installation and disassembly of the quick interface component convenient, facilitating the movement and maintenance of the machine without any impact; by using the Y-shaped connector 3, the head end head 32 is in a V or U shape, optimizing the pipeline and eliminating the occurrence of "dead space", and having a good antibacterial effect. Multi-stage cones 321 are arranged outside the head end head 32 of the Y-shaped connector 3. When making an intubation connection, it can ensure the sealing effect, making the pipeline connection method more refined, enabling it to connect to a very small-diameter sanitary silicone tube (the same as the hemodialysis machine pipeline), effectively reducing the waste of the original liquid and improving the disinfection efficiency during use; in addition, the quick interface component of this embodiment can be operated with one hand, which is convenient to use.

[0029] In this embodiment, there are two quick connectors 2 and two Y-shaped connectors 3. The two quick connectors 2 and the two Y-shaped connectors 3 are arranged one above the other on the bracket 1, and the two quick connectors 2 and the two Y-shaped connectors 3 are arranged in one-to-one correspondence. In this way, two groups of pipelines can be connected to achieve different functions.

[0030] In this embodiment, the quick-connect assembly also includes a retractable cover 5, one end of which is connected to the bracket 1 via a rotating shaft. The cover 5 is located on the side of the bracket 1 where the quick connector 2 is located. When the cover 5 is engaged, it covers the quick connector 2. When the cover 5 is raised, the quick connector 2 is exposed, facilitating connection of the corresponding pipeline. Optionally, the rotating shaft can be a damping shaft. In this way, when the cover 5 is raised, it can remain in the raised position and will not buckle naturally, facilitating connection and removal of pipelines.

[0031] In this embodiment, a through-hole is provided at the location of the bracket 1 where the quick connector 2 and the Y-connector 3 are provided. The tail of the quick connector 2 is provided with an internal thread, and the outside of the tail end cap 31 is provided with an external thread. A portion of the tail end cap 31 is passed through the through-hole, and the tail end cap 31 is screwed onto the tail of the quick connector 2 and sealed by a sealing gasket 7. In this way, a sealed connection between the quick connector 2 and the Y-connector 3 is achieved. A nut 6 is screwed onto the outside of the tail end cap 31. The nut 6 is located on the side of the bracket 1 facing away from the quick connector 2. Since the nut 6 and the quick connector 2 are both screwed onto the tail end cap 31 of the Y-connector 3, the Y-connector 3 and the quick connector 2 can be fixed to the bracket 1 by screwing the nut 6 in the opposite direction.

[0032] In this embodiment, the fixing clamp 4 is a C-shaped clamp, the opening of which is located on the side away from the bracket 1, and can be clamped with the brine rod, and the side wall of the C-shaped clamp is provided with a threaded hole 41. After clamping, the top screw is tightened in the threaded hole 41 to tighten the brine rod through the top screw, thereby ensuring that the quick interface assembly does not slide downward; the fixing clamp 4 is connected to the bracket 1 by screws to form a whole.
