A test aid for a dialyzer product

Abstract

This application proposes a testing auxiliary device for dialyzer products, comprising: a base with a first connection port and a mounting slot communicating with each other; and an adapter component with a first connector. The base is fastened to the adapter component through the mounting slot, and the first connector is inserted through the first connection port. The diameter of the first connector is smaller than the diameter of the first connection port, allowing the adapter component to move along a first direction of the base within the mounting slot. This first direction is perpendicular to the extension direction of the first connection port. This effectively solves the technical problem in the prior art where the dialyzer Hansen interface is easily damaged during testing due to dimensional tolerances. It achieves a better adapter connection, significantly reducing lateral forces and eccentric stresses caused by forced docking, and reducing the risk of damage such as plastic deformation, micro-cracks, or sealing failure of the Hansen interface during insertion and removal. This effectively protects the structural integrity of the dialyzer under test, thereby improving the product qualification rate.

Description

Technical Field

[0001] This application relates to the technical field of medical devices, and more particularly to a testing auxiliary device for dialyzer products. Background Technology

[0002] The dialyzer is the core equipment in blood purification therapy, primarily used to remove metabolic waste and excess water from the patient's blood, as well as maintain electrolyte and acid-base balance. Its working principle involves separating blood and dialysate through a semi-permeable membrane, utilizing the concentration gradient to achieve substance exchange. In clinical use, the dialyzer needs to be connected to the dialysis machine via a tubing system. The Hansen connector, as a quick and safe connection device, is widely used in the arterial and venous ports and dialysate interfaces of dialyzers. The Hansen connector allows for quick connection or disconnection of fluid lines without tools, ensuring a tight seal, making it ideal for the transmission of gases, liquids, and other media.

[0003] Currently, in the production and quality control of dialyzers, dedicated airtightness testing equipment is commonly used to test the performance of dialysis membranes. This type of testing equipment is typically equipped with an adapter device with a matching adapter hole for the Hansen connector. By inserting the Hansen connector on the dialyzer into this adapter hole, the pipeline connection between the testing equipment and the dialyzer is established. Subsequently, the testing system introduces gas (such as compressed air) at a certain pressure and determines the presence of leaks using pressure decay or flow detection methods. This type of testing method is highly automated, enabling rapid, batch online testing, and is widely used in the final inspection process of dialyzer production lines. As a key component connecting the testing equipment and the dialyzer under test, the design of the adapter device directly affects the accuracy and reliability of the testing.

[0004] However, existing technical solutions have significant drawbacks. Because the dialyzer shell is made of rigid plastic, dimensional tolerances are unavoidable during injection molding and assembly, leading to deviations in the actual position and angle of multiple Hansen interfaces across different batches or even the same dialyzer. Furthermore, the adapter holes in existing testing equipment are fixed in position and cannot be adaptively adjusted based on the actual position of the interface being tested. During testing, when operators forcefully align and insert the dialyzer's Hansen interface into the fixed adapter hole, misalignment can easily cause lateral stress or eccentric insertion. This can not only lead to plastic deformation or micro-cracks in the Hansen interface body or sealing structure, affecting its normal use, but also cause wear on the adapter device, reducing testing accuracy. In addition, frequent forced insertion and removal accelerate interface aging, and may even cause product scrapping during testing, increasing production costs and affecting the stability of test results. Utility Model Content

[0005] This application provides a testing auxiliary device for dialyzer products. By adopting a separate design for the base and the adapter component, and allowing the adapter component to move within the mounting slot of the base, it effectively solves the technical problem in the prior art where the dialyzer Hansen interface is easily damaged during testing due to dimensional tolerances. The technical solution is as follows:

[0006] This application provides a testing auxiliary device for a dialyzer product, including: a base with a first connection port and a mounting slot communicating with each other; and an adapter with a first connector, wherein the base is fastened to the adapter through the mounting slot and the first connector is inserted through the first connection port;

[0007] The diameter of the first connector is smaller than the diameter of the first connection port, so that the adapter can be displaced in the mounting slot along a first direction of the base, which is perpendicular to the extension direction of the first connection port.

[0008] In one embodiment, the diameter of the adapter is smaller than the diameter of the mounting slot, so that the adapter can be adjusted in position in the mounting slot along a second direction of the base, the second direction being perpendicular to the extension direction of the first connection port and the first direction.

[0009] In one embodiment, the base is further provided with a second connection port communicating with the mounting slot, the second connection port being located on the side of the base adjacent to the first connection port; the adapter is further provided with a second connector communicating with the first connector, the extension direction of the second connector being perpendicular to the extension direction of the first connector.

[0010] When the adapter is inserted into the mounting slot, the second connector is inserted into the second connection port, and the diameter of the second connector is smaller than that of the second connection port.

[0011] In one embodiment, the adapter is further provided with a toggle part on the side opposite to the second connector, the toggle part extending out of the mounting slot in a third direction opposite to the second direction.

[0012] In one embodiment, the end face of the actuating part facing away from the second connector is configured as an arc-shaped structure.

[0013] In one embodiment, the number of bases is set to two, and the second connection ports on the two bases are arranged opposite to each other; the number of adapter components is set to at least two, and they are respectively configured in the mounting slots of the corresponding bases.

[0014] In one embodiment, the base is configured as a cuboid structure, having a first side extending along the length direction, a second side adjacent to the first side, and the remaining third and fourth sides; the first side is provided with a plurality of first connection ports arranged along the length direction of the base; the second side is provided with a plurality of second connection ports arranged along the length direction of the base, and each second connection port corresponds to each first connection port; the third and fourth sides are provided with a plurality of mounting slots arranged along the length direction of the base, and each mounting slot corresponds to each first connection port; the number of adapter components corresponds to the number of mounting slots, and each adapter component is configured in the corresponding mounting slot.

[0015] In one embodiment, it further includes: a support component mounted on the base, the support component having a limiting notch corresponding to the first connection port.

[0016] In one embodiment, it further includes a sealing ring disposed in the insertion hole of the first connector for interference fit onto the target plug of the dialyzer product.

[0017] In one embodiment, the socket of the first connector is configured as a flared structure that gradually increases in size towards its outer end, and the minimum diameter of the flared structure socket can be greater than the diameter of the target plug.

[0018] Compared with existing technologies, the test auxiliary device for dialyzer products proposed in the above technical solution allows the adapter component to move within the mounting slot along a first direction perpendicular to the extension direction of the first connection port because the diameter of the first connector is smaller than that of the first connection port. This allows the adapter component to automatically adjust its position to adapt to the actual spatial position and angular deviation when the Hansen interface is inserted into the first connector, resulting in a better adapter connection. This significantly reduces the lateral force and eccentric stress generated by forced docking, lowers the risk of damage such as plastic deformation, micro-cracks, or seal failure of the Hansen interface during insertion and removal, effectively protects the structural integrity of the dialyzer under test, and thus improves the product qualification rate.

[0019] In summary, the testing auxiliary device for dialyzer products presented in this application has a simple structure, is easy to manufacture and maintain, and is suitable for online testing in automated production lines. By reducing losses and equipment wear during the testing process, it extends the device's service life, reduces production costs and maintenance frequency, and has good practicality and economy, providing a safe and efficient technical solution for dialyzer product quality control.

[0033] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0034] Reference Figures 1 to 4 As shown, an embodiment of this application proposes a testing auxiliary device for a dialyzer product. The testing auxiliary device for the dialyzer product may include: a base 1, which is provided with a first connection port 101 and a mounting slot 103 that are interconnected; and an adapter 2, which is provided with a first connector 201. The base 1 is fastened to the adapter 2 through the mounting slot 103, and the first connector 201 is inserted through the first connection port 101.

[0035] The diameter of the first connector 201 is smaller than the diameter of the first connection port 101, so that the adapter 2 can be displaced in the mounting slot 103 along the first direction of the base 1, which is perpendicular to the extension direction of the first connection port 101.

[0036] Specifically, in the technical solution adopted in this application, the first connector 201 can be located on the top of the adapter component 2, so that when the base 1 is fastened to the adapter component 2 through the mounting slot 103, the first connector 201 can pass through the first connection port 101. The first connector 201 can be used to connect the Hansen interface of the dialyzer product. In use, the dialyzer product is supported on the base 1, and the Hansen interface is connected to the first connector 201 through the first connection port 101. When the diameter of the first connector 201 is smaller than that of the first connection port 101, the adapter component 2 can be displaced at least along the extension direction of the mounting slot 103. This direction can be the width direction of the base 1, which is defined as the first direction in this application for convenience. When the Hansen interface is inserted into the first connector 201 through the first connection port 101, the adapter component 2 can be adjusted in position in the mounting slot 103 according to the existing tolerance dimensions, so that the position of the first connector 201 can better match the actual position of the Hansen interface, effectively avoiding structural conflicts between the Hansen interface and the first connector 201 due to tolerance dimensions, and significantly reducing damage to the dialyzer product during the testing process.

[0037] Furthermore, refer to Figure 2 As shown, in some embodiments, the diameter of the adapter 2 is smaller than the diameter of the mounting slot 103, so that the adapter 2 can be adjusted in the mounting slot 103 along a second direction of the base 1, the second direction being perpendicular to the extension direction of the first connection port 101 and the first direction.

[0038] Specifically, in the technical solution adopted in this application, in order to further enhance the flexibility of the adapter component 2 in adapting to the Hansen interface, the size of the adapter component 2 is smaller than the diameter of the mounting slot 103, so that the adapter component 2 can be displaced along the width direction of the mounting slot 103, that is, also understood as the length direction of the base 1, which is defined in this application as a second direction perpendicular to the first direction and the extension direction of the first connection port 101. Thus, the adapter component 2 can move freely in one planar direction within the mounting slot 103, that is, in use, the position of the adapter component 2 can be adjusted along the length and width directions of the base in the mounting slot 103, so that when the dialyzer product is placed on the base 1, the first connector 201 adapts to the tolerance diameter of the Hansen interface in different directions by the displacement of the first connection port 101.

[0039] Furthermore, refer to Figures 1 to 4As shown, in some embodiments, the base 1 is further provided with a second connection port 102 communicating with the mounting slot 103. The second connection port 102 is located on the side of the base 1 adjacent to the first connection port 101. The adapter 2 is further provided with a second connector 202 communicating with the first connector 201. The extension direction of the second connector 202 is perpendicular to the extension direction of the first connector 201.

[0040] When the adapter 2 is inserted into the mounting slot 103, the second connector 202 is inserted into the second connection port 102, and the diameter of the second connector 202 is smaller than that of the second connection port 102.

[0041] Specifically, in the technical solution adopted in this application, in order to enable the Hansen interface to connect to the testing equipment through the adapter component 2, a second connector 202 is provided on the adapter component 2 to connect to the first connector 201. The second connector 202 is used to connect to the testing equipment. The base 1 is provided with a second connection port 102 for accommodating the second connector 202. The diameter of the second connection port 102 is larger than the diameter of the second connector 202, so as to avoid the second connection port 102 from excessively limiting the second connector 202, which would cause the displacement of the adapter component 2 in the mounting slot 103 to be blocked.

[0042] Furthermore, refer to Figure 1 and Figure 4 As shown, in some embodiments, the adapter 2 is further provided with a toggle part 203 on the side opposite to the second connector 202, and the toggle part 203 extends out of the mounting slot 103 along a third direction opposite to the second direction.

[0043] Specifically, in the technical solution adopted in this application, the position of the adapter 2 in the mounting slot 103 can be initially adjusted by hand using the toggle 203 so that when the dialyzer product is supported on the base 1, the Hansen interface on the dialyzer product can correspond to the first connector 201. When the Hansen interface is inserted into the first connector 201, the entire adapter 2 is displaced in the mounting slot 103 according to the tolerance dimensions of the Hansen interface so that the position of the first connector 201 is fully adapted to the Hansen interface.

[0044] Furthermore, refer to Figure 1 and Figure 4 As shown, in some embodiments, the end face of the actuating part 203 facing away from the second connector 202 is configured as an arc-shaped structure.

[0045] Specifically, in the technical solution adopted in this application, the arc-shaped end face of the dialyzer part 203 can improve the comfort of the contact process when the operator touches it, and can also prevent serious bumps and injuries when the dialyzer product accidentally touches the dialyzer part 203. During the manufacturing process, a chamfering process can be performed on the end face of the dialyzer part 203, so that the outer end face of the dialyzer part 203 forms an arc-shaped structure.

[0046] Furthermore, refer to Figure 1 As shown, in some embodiments, the number of bases 1 is set to two, and the second connection ports 102 on the two bases 1 are arranged opposite to each other; the number of adapter components 2 is set to at least two, and they are respectively configured in the mounting slots 103 of the corresponding bases 1.

[0047] Specifically, in the technical solution adopted in this application, since dialyzer products generally have two Hansen interfaces, the number of bases 1 in the dialyzer product testing auxiliary device of this application can be set to two. In order to test at least one dialyzer product, the number of adapter parts 2 is also set to two, so that the Hansen interfaces can be connected in the corresponding bases 1 through the first connector 201. In use, the testing equipment can be connected to the second connector 202 through the second connection port 102, so that the testing equipment can connect to the Hansen interfaces on the dialyzer product.

[0048] Furthermore, refer to Figures 1 to 3 As shown, in some embodiments, the base 1 is configured as a cuboid structure, having a first side extending along the length direction, a second side adjacent to the first side, and the remaining third and fourth sides; the first side is provided with a plurality of first connection ports 101 arranged along the length direction of the base 1; the second side is provided with a plurality of second connection ports 102 arranged along the length direction of the base 1, and each second connection port 102 corresponds one-to-one with each first connection port 101; the third and fourth sides are provided with a plurality of mounting slots 103 arranged along the length direction of the base 1, and each mounting slot 103 corresponds one-to-one with each first connection port 101; the number of adapter components 2 corresponds to the number of mounting slots 103, and each adapter component 2 is configured in the corresponding mounting slot 103.

[0049] Specifically, in the technical solution adopted in this application, in order to test multiple dialyzer products simultaneously, the base 1 can be configured as a cuboid structure to accommodate more dialyzer products. The first side can be the top side of the base 1, while the second and third sides can be sides on the base 1 adjacent to the first side, and the fourth side is opposite to the first side. To facilitate the connection between the Hansen interface and the first connector 201 via the first connection port 101, several first connection ports 101 arranged along the length of the base 1 can be opened on the first side, with the first connection ports 101 arranged in a straight line. Several second connection ports 102 arranged along the length of the base 1 can be opened on the second side, with each second connection port 102 corresponding to one of the first connection ports 101. The number of mounting slots 103 on the base 1 corresponds to the number of first connection ports 101, and the slots of the mounting slots 103 are extended and formed on the third and fourth sides to facilitate the mounting of the adapter component 2 into the base 1 via the mounting slots 103. This allows for the configuration of several adapter components 2 on the base 1, enabling multiple dialyzer products to be simultaneously supported on a test auxiliary device with two bases 1, and matching the two Hansen interfaces on each dialyzer product.

[0050] Furthermore, refer to Figure 1 As shown, in some embodiments, it further includes: a support component 3, which is mounted on the base 1, and the support component 3 is provided with a limiting notch 301 that corresponds one-to-one with the first connection port 101.

[0051] Specifically, in the technical solution adopted in this application, the support component 3 can be configured as a plate-like structure, which can be detachably installed on the base 1 by fasteners. Several limiting notches 301 corresponding one-to-one with the first connection port 101 are provided on the support component 3. In use, the dialyzer product can be placed above the base 1 via the support component 3, specifically, the end of the dialyzer product is embedded in the corresponding limiting notch 301. During use, after the Hansen interface is inserted into the first connector 201 through the first connection port 101, the support component 3 bears most of the weight of the dialyzer product, effectively preventing damage to the Hansen interface due to excessive weight.

[0052] Furthermore, in some embodiments, a sealing ring is also included, disposed in the insertion hole of the first connector 201, for fitting onto the target plug of the dialyzer product in an interference fit manner.

[0053] Specifically, in the technical solution adopted in this application, a sealing ring is disposed in the middle of the insertion hole of the first connector 201. The diameter of the sealing ring is smaller than that of the target plug of the dialyzer product, and the interface on the target plug is the Hansen interface. In use, the force applied by the target plug when it is inserted into the insertion hole of the first connector 201 can cause the sealing ring to be fitted onto the target plug, thereby achieving the effect of sealing the target plug within the first connector 201.

[0054] Furthermore, in some embodiments, the socket of the first connector 201 is configured as a flared structure that gradually increases towards its outer end, and the minimum diameter of the flared structure socket can be greater than the diameter of the target plug.

[0055] Specifically, in the technical solution adopted in this application, the socket of the first connector 201 adopts a flared structure to avoid the first connector 201 excessively restricting the target plug with the Hansen interface. When the target plug of the dialyzer product is inserted into the first connector 201, the sealing ring can be tightly supported between the outer wall of the target plug and the inner wall of the first connector 201 to achieve a sealing effect. The target plug can also move slightly in the socket of the first connector 201, so that the target plug and the Hansen interface on the target plug are not easily seriously damaged in the first connector 201.
