Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to an adapter for a blood purification container, and a blood purification container including the adapter. Background Technology

[0002] Blood purification is an effective treatment for serious conditions such as kidney failure, and includes dialysis, filtration, adsorption, and replacement. During blood purification, dialysate is used to exchange substances with the blood, thus purifying it. Dialysate is prepared by mixing dialysis powder and a solution, or dialysis solution A and dialysis solution B. Typically, the dialysis powder or dialysis solution B is contained in a container, such as a powder cartridge or a dialysate cartridge, which has an inlet for the solution and an outlet for the prepared dialysate.

[0003] When this container is connected to a fluid supply device or directly to a blood purification device, the external tubing is connected to the connector for fluid injection and dispensing. The container is reusable; for example, after each use, it can be removed from the device or cleaned by connecting it to a cleaning device before reuse. However, with repeated use, the connector is prone to damage; for instance, the sensor inside the connector that checks the connection between the external tubing and the connector may malfunction. Currently, the connector and container body are integrated; if the connector is damaged, the container becomes unusable, requiring replacement of the entire container and increasing costs. Utility Model Content

[0004] In view of this, the present application aims to provide a container adapter for blood purification. This adapter can be easily installed and removed from containers of existing specifications, ensuring the connection between the container and external pipelines without changing the existing container structure, and solving the problem of increased costs caused by the need to replace the entire container after the adapter is damaged.

[0005] This application provides a blood purification container adapter, applicable to blood purification containers, wherein the blood purification container is provided with an integral connector that is integrally connected to the container body, including:

[0006] The adapter ring is configured for detachable connection to an integrated connector on the container;

[0007] A connector is attached to the adapter ring and is equipped with a sensor. The connector is configured to communicate with the integrated connector and to connect to the external pipeline.

[0008] In one possible implementation, the connector head is provided with a connection structure that connects to the external pipeline, and the connection structure is configured to be the same as the external connection structure of the integrated connector.

[0009] In one possible implementation, the inner wall of the adapter ring is provided with an internal thread structure, and is connected to the integral connector through the internal thread structure.

[0010] And / or, the connector is inserted into the adapter ring, and the connector is provided with an external thread structure that connects to the external pipeline.

[0011] In one possible implementation, the connector includes a connector portion for connecting to the external pipeline and a connecting portion for connecting to the integral connector, the connecting portion being used for a sealed connection with the integral connector.

[0012] In one possible implementation, the connector includes a connecting pipe section, the outer wall of the lower end of the connecting pipe section is provided with a sealing groove and a sealing ring disposed in the sealing groove, and the lower end of the connecting pipe section is used to insert into the integrated connector and seal with the integrated connector.

[0013] In one possible implementation, the connector is rotatably connected to the adapter ring.

[0014] In one possible implementation, the connector includes a connecting pipe section and a stop ring protruding from the outer wall of the connecting pipe section. A retaining ring is provided between the adapter ring and the connecting pipe section. The retaining ring is embedded in a groove on the inner wall of the adapter ring and presses against the stop ring. The bottom end of the stop ring is used to abut against the integrated connector.

[0015] In one possible implementation, the connector includes a connector section with a diameter larger than that of the connecting section, and an avoidance groove is formed between the stop ring and the connector section.

[0016] In one possible implementation, the outer wall of the adapter ring is provided with protrusions, and at least two protrusions are distributed along the circumference of the adapter ring.

[0017] This application also provides a blood purification container, including a container body, an inlet connector and an outlet connector disposed on the container body, wherein the inlet connector and / or the outlet connector are blood purification container adapters as described in any of the above claims.

[0018] The blood purification container adapter provided in this application can be connected to the container's integrated connector via an adapter ring. The adapter ring also features a connector with a sensor for connecting external piping. Essentially, it adds an intermediate adapter to the container, ensuring a secure connection between the external piping and the container, and avoiding frequent disassembly and reassembly of the container's integrated connector and the external piping.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Dialysis solution is prepared by mixing dialysis powder and a solution, or dialysis solution A and dialysis solution B. Typically, the dialysis powder or dialysis solution B is contained in a container, such as a powder container or a dialysis solution container. The container is equipped with an inlet for the solution to enter and an outlet for the prepared dialysis solution to flow out.

[0032] When this container is connected to a fluid supply device or directly to a blood purification device, the external tubing is connected to the connector for fluid injection and dispensing. The container is reusable; for example, after each use, it can be removed from the device or cleaned by connecting it to a cleaning device before reuse. However, with repeated use, the connector is prone to damage. For example, cleaning damage and excessive use can cause the sensor inside the connector to malfunction, or wear can lead to insufficient connection and sealing. Currently, the connector and container body are integrated in the existing containers. If the connector is damaged, the container becomes unusable, requiring complete replacement and increasing costs.

[0033] To solve the above problems, please refer to the appendix. Figure 1-6 This application provides a blood purification container adapter (hereinafter referred to as the adapter). The adapter is suitable for containers with an integrated connector 6, that is, the container has an integrated connector 6 that is integrally connected to the container body. The adapter includes an adapter ring 2 and a connector 1 connected to the adapter ring 2. The adapter ring 2 is configured to be detachably connected to the integrated connector 6 on the container. The connector 1 is connected to the adapter ring 2 and is provided with a sensor 5. The connector 1 is configured to communicate with the integrated connector 6 and be connected to an external pipeline.

[0034] That is, the adapter is detachably connected to the container's integrated connector 6 and to the external pipeline, thus connecting the external pipeline to the container. Simultaneously, the adapter is equipped with a sensor 5, which can detect whether the directly connected external pipeline is properly connected, eliminating the need to use the container's integrated connector 6 to directly connect the pipeline and perform the sensing. Each time the container is connected to the equipment, the external pipeline is connected to the adapter; when the container is disassembled, the connection between the external pipeline and the adapter is disconnected, and the adapter and container are removed together, significantly reducing the use of the container's own connector.

[0035] As can be seen, the adapter provided in this application can be connected to the integrated connector 6 on the container via the adapter ring 2. At the same time, the adapter ring 2 is also provided with a connector 1 that can connect to the external pipeline and has a sensor 5. It is equivalent to adding an intermediate adapter to the container to ensure the connection between the external pipeline and the container. Since the connector can be detachably connected to the container via the adapter ring 2, it can be replaced separately after the connector is damaged due to repeated use, without having to replace the entire container, which effectively reduces costs. At the same time, it is also convenient to disassemble the adapter for separate cleaning after use, thereby reducing damage to the sensor 5.

[0036] Furthermore, connector 1 is provided with a connection structure for connecting to the external pipeline, and the connection structure is configured to be the same as the external connection structure of the integrated connector 6. With this configuration, the structure on connector 1 that connects to the external pipeline is identical to the external connection structure of the integrated connector 6, both being threaded or snap-fit ​​connections, etc. Therefore, the external pipeline on the equipment does not require structural adjustments and remains compatible with the adapter; in other words, the adapter can be directly adapted to the original container and equipment without any adjustments, demonstrating high applicability.

[0037] Preferably, the connection structure described above can be a threaded structure. For example, the inner wall of the adapter ring 2 is provided with an internal thread structure 22, and is connected to the integrated connector 6 through the internal thread structure 22; the connector 1 passes through the adapter ring 2, and the connector 1 is provided with an external thread structure 111 connected to the external pipeline.

[0038] Various sizes of container connectors typically have external thread structures, which connect to external pipelines via these threaded connections. The adapter of this application has an internal thread structure 22 on the adapter ring 2 and an external thread structure 111 on the connector 1 that is identical to that on the integrated connector 6 on the container. This allows it to be adapted to such connectors on containers of various sizes; and the threaded connection operation is convenient and quick.

[0039] The threads in the internal thread structure 22 and the external thread structure 111 in this article can be continuous threads or include multiple spaced thread segments.

[0040] Of course, the adapter ring 2 and the integrated connector 6 can also be connected by a snap-fit ​​structure or a quick-connect structure, and the connector 1 and the external pipeline can also be connected by a snap-fit ​​structure or a quick-connect structure (a quick-connect structure refers to a snap-fit ​​and / or snap ring 4 and a sealing ring between the two connected pipes, such as a quick-connect male and female connector on a pipeline).

[0041] The adapter ring 2 is annular, with an internal thread structure 22 on its inner wall and protrusions 21 on its outer wall. At least two protrusions 21 are distributed circumferentially along the adapter ring 2. The protrusions 21 facilitate the operator to screw the adapter ring 2, simplifying the assembly and disassembly of the adapter.

[0042] The connector 1 includes a connector portion and a connecting portion arranged sequentially along the axial direction. The connector portion is used to connect to an external pipeline. The connecting portion is used to make a sealing connection with the integrated connector 6. In this way, the connector 1 is directly sealed to the integrated connector 6, directly connecting the external pipeline and the container, without the need for the adapter ring 2 to intervene in the liquid flow path, and without the need for a sealing connection with the adapter ring 2. This simplifies the structure and also helps to enhance the sealing performance.

[0043] Specifically, such as Figure 2 and Figure 3 As shown, connector 1 is tubular, or it can be said to include a connecting pipe, which is divided into a connector section 11 and a connecting pipe section 12 along the axial direction. The connector part includes the connector section 11, and the connecting part includes the connecting pipe section 12.

[0044] The connector section connects to the external pipeline. The outer wall of the connector section 11 is provided with an external thread structure 111, configured to be identical to the external connection structure of the integrated connector 6. Preferably, the shape and diameter of the connector section are also identical to those of the integrated connector 6. In other words, the overall structure of the connector section is the same as the structure of the integrated connector 6 on the container.

[0045] The connector pipe section 11 is also provided with an inner groove 103, which can be arranged axially to accommodate the sensor 5 and seal the opening of the sealing groove 101, or in other words, seal the sensor 5. The sealing element can specifically be a sealant, a sealing plug, or a sealing film such as an aluminum foil film.

[0046] For example, the sealing connection between connector 1 and integrated connector 6 is achieved by providing a sealing groove 101 and a sealing ring 3 within the sealing groove 101 on the outer wall of the lower end of the connecting pipe section 12. The lower end of the connecting pipe section 12 is inserted into the integrated connector 6 and sealed with it. With this configuration, when connecting the adapter to the container, simply insert the lower end of connector 1 into the integrated connector 6 and screw the adapter ring 2 to thread it onto the integrated connector 6, thus completing the connection between the adapter and the integrated connector 6 on the container. This operation is simple.

[0047] The connection between connector 1 and adapter ring 2 can be a fixed connection or a relatively rotatable connection. For example, in some embodiments, the connector and adapter ring 2 are rotatably connected.

[0048] If the connector 1 and the adapter ring 2 can rotate relative to each other, and the adapter ring 2 is screwed on to connect with the integrated connector 6, the connector 1, which is sealed and plugged into the integrated connector 6, does not need to rotate with it, which simplifies the connection operation. Moreover, this structure makes the adapter suitable for containers with an elliptical integrated connector 6, thus making it more adaptable.

[0049] For example, such as Figure 2 , Figure 3 and Figure 6 As shown, the connecting part includes a connecting pipe section 12 and a stop ring 121 protruding from the outer wall of the connecting pipe section 12. A retaining ring 4 is provided between the adapter ring 2 and the connecting pipe section 12. A retaining groove for the retaining ring 4 to be inserted is provided on the inner wall of the adapter ring 2. Then, the outer side of the retaining ring 4 is inserted into the retaining groove on the inner wall of the adapter ring 2 in the radial direction, and the inner side presses against the stop ring 121. The bottom end of the stop ring 121 is used to abut against the integrated connector 6.

[0050] Thus, connector 1 is inserted through adapter ring 2, and adapter ring 2 is sleeved on connector 1, specifically sleeved on connecting pipe section 12; at the same time, adapter ring 2 has a retaining spring 4 to press against the outwardly protruding stop ring 121 on connecting pipe section 12 to prevent connector 1 from coming out from the top; while stop ring 121 is blocked by the internal thread on the inner wall of adapter ring 2 and will not come out from the bottom of adapter ring 2.

[0051] During the manufacturing process, the connecting pipe section 12 of the connector 1 can be inserted into the adapter ring 2 from above and downwards, and then the retaining ring 4 can be added to prevent the connector 1 from coming out.

[0052] When the adapter and the integrated connector 6 are connected, the lower end of the connecting pipe section 12 is inserted into the integrated connector 6. As the adapter ring 2 is turned, the adapter ring 2 moves downward. At the same time, because the retaining spring 4 presses against the stop ring 121, it will push the connector 1 downward until the stop ring 121 on the connector 1 abuts against the top of the integrated connector 6. Thus, as Figure 6 As shown, the stop ring 121 is pressed against the integrated connector 6 by the snap ring 4 on the adapter ring 2, thereby achieving a connection between the adapter and the integrated connector 6 with high stability and good sealing.

[0053] On the connecting pipe section 12, at least the section used for insertion into the integrated connector 6, that is, the section located axially below the stop ring 121 (away from the side of the connector pipe section 11), has an outer diameter smaller than the outer diameter of the connector pipe section 11. The outer diameter of the connector pipe section 11 is the same as the outer diameter of the integrated connector 6. The section of the connecting pipe section 12 located below the stop ring 121 is used for insertion into the cavity of the integrated connector 6.

[0054] The section of the connecting pipe section 12 located above the stop ring 121 (on the side closer to the connector pipe section 11) is also directly and integrally connected to the connector pipe section 11. Its diameter can also be smaller than that of the connector pipe section 11, thus forming a clearance groove 102 between the stop ring 121 and the connector pipe section 11. The clearance groove 102 makes it easier for the retaining spring 4 to be inserted above the stop ring 121 and press against the stop ring 121.

[0055] It should be noted that the directional terms such as "above," "below," "top," "bottom," "apex," "bottom," and "lower end" in the above text describe the orientation of the product as shown in the attached diagram. If the product's orientation changes, the directional terms should also change accordingly.
