Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical devices, and in particular to a mounting assembly. Background Art
[0002] In the medical device field, particularly in blood purification treatments, extracorporeal circuit components must remain sealed before connecting to the device to maintain a sterile environment. These components, such as connector caps and pressure sensor covers, are typically connected via threaded connections to facilitate removal and reconnection of the tubing when needed.
[0003] However, existing threaded connections carry the risk of falling apart, particularly during production, transportation, or clinical operation. Once a component falls off, it not only compromises the sterile environment within the tubing, but can also waste consumables and even threaten patient safety. Therefore, an improved component design is needed to address the issue of falling apart during medical device use and ensure the stability and safety of the tubing system. Utility Model Content

[0011] In some embodiments, the rod portion extends in a first direction, and the first matching portion is located at a first end of the rod portion in the first direction.

[0014] In some embodiments, in a circumferential direction of the rod portion that is perpendicular to the first direction, the first matching portion includes a plurality of protrusion units that are spaced apart along the circumferential direction at the first end of the rod portion.
[0015] In some embodiments, the circumferential direction of the rod portion is perpendicular to the first direction, and the shape of the first matching portion in a cross section perpendicular to the circumferential direction is semicircular or triangular.
[0016] In some embodiments, the rod portion is extended in a first direction; and the positioning component includes:
[0017] a fixing member, fixedly sleeved on the rod portion, the fixing member being provided with the first thread structure;
[0018] a movable member, movably sleeved on the rod portion, the movable member being movable along the first direction and rotating about the first direction, the movable member having a range of movement limited by the first matching portion and the fixed member, and the movable member being provided with a third thread structure;

Through the combination of the fixed structure and the movable structure, the first thread structure and the third thread structure form a continuous thread.
[0020] In some embodiments, the fixed structure is a block, and the movable structure is a notch. In the first direction of the rod and in a circumferential direction perpendicular to the first direction, the block and the notch are matched in a concave-convex manner.
[0021] In some embodiments, the number of the fixed structure and the number of the movable structure are both set to multiple; in the circumferential direction of the fixed part perpendicular to the first direction, the multiple fixed structures are evenly distributed at a first interval; in the circumferential direction of the movable part perpendicular to the first direction, the multiple movable structures are evenly distributed at a second interval; wherein the first interval and the second interval have a straight interval angle; and / or,

The key innovation is that the mounting sleeve also has an internal second mating portion, which is connected to the first mating portion by an interference fit.
[0027] Interference fit, as a non-threaded mechanical connection method, provides an additional safeguard. While threaded connections can loosen or fall out due to various factors (such as vibration and pressure fluctuations), interference fit ensures a secure connection, effectively preventing components from falling out. This dual safeguard significantly improves the safety and reliability of medical device piping systems. By ensuring the piping remains sealed, it prevents damage to the sterile environment and waste of consumables.
[0028] Combined with the above structure and process description, it can be seen that the installation component has at least the following beneficial effects: the installation component provides double protection for the medical device installation component by introducing interference fit as a second connection method besides threaded connection, effectively avoiding the destruction of the sterile environment and waste of consumables caused by the falling off of the threaded connection, and enhancing the safety and reliability of the connection.

[0045] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0046] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0047] In the accompanying drawings, coordinate axes are marked, and the directions indicated by the coordinate axes are consistent with the directions described in the present application. Coordinate axis X represents a first direction, which is also the length direction, left-right direction, and axial direction.
[0048] Please refer to Figures 1 to 3 ,in, Figure 1 A schematic diagram of an installation assembly provided in an embodiment of the present application, Figure 2 for Figure 1 Schematic diagram of the positioning components, Figure 3 for Figure 1 Schematic diagram of the installed components.
[0049] In a first specific embodiment, the installation assembly provided by the embodiment of the present application mainly includes a connected positioning component 100 and an installation component 200; wherein, the positioning component 100 includes a positioning rod 1, the positioning rod 1 is provided with a connected rod portion 11 and a first matching portion 12, and the positioning rod 1 is provided with a first threaded structure 21; the installation component 200 includes a mounting sleeve 4, the mounting sleeve 4 has an at least partial opening 41 formed therein for accommodating the positioning component 100, the mounting sleeve 4 is provided with a second threaded structure 42, the second threaded structure 42 is used to be connected to the first threaded structure 21, the mounting sleeve 4 is provided with a second matching portion 43, the second matching portion 43 is used to interference fit with the first matching portion 12.
[0050] In the medical device field, especially in blood purification treatments, components of extracorporeal circuits must remain sealed to maintain a sterile environment. Traditionally, these components are connected via threaded connections. While this facilitates disassembly and reconnection, it carries the risk of dislodging, particularly during production, transportation, or clinical operation. Dislodging not only compromises the sterile environment within the circuit, but can also lead to waste of consumables and even threaten patient safety.
[0051] To address this issue, the installation assembly provided in this application has been innovatively designed. The assembly consists of a connected positioning component 100 and a mounting component 200. The positioning rod 1 in the positioning component 100 includes a rod portion 11 and a first mating portion 12, and is provided with a first threaded structure 21. The mounting sleeve 4 in the mounting component 200 has an open cavity 41 therein for accommodating at least a portion of the positioning component 100, and a second threaded structure 42 is provided inside the mounting sleeve 4, which is connected to the first threaded structure 21. The key innovation is that a second mating portion 43 is also provided inside the mounting sleeve 4, which is connected to the first mating portion 12 by an interference fit.
[0052] Interference fit, as a non-threaded mechanical connection method, provides an additional safeguard. While threaded connections can loosen or fall out due to various factors (such as vibration and pressure fluctuations), interference fit ensures a secure connection, effectively preventing components from falling out. This dual safeguard significantly improves the safety and reliability of medical device piping systems. By ensuring the piping remains sealed, it prevents damage to the sterile environment and waste of consumables.
[0053] Combined with the above structure and process description, it can be seen that the installation component has at least the following beneficial effects: the installation component provides double protection for the medical device installation component by introducing interference fit as a second connection method besides threaded connection, effectively avoiding the destruction of the sterile environment and waste of consumables caused by the falling off of the threaded connection, and enhancing the safety and reliability of the connection.
[0054] In some cases, the connection between the mounting component 200 and the positioning component 100 can be regarded as the installation of a nut on a screw; its material includes but is not limited to plastic, metal, etc.; application scenarios include but are not limited to any screw and nut structure with anti-falling requirements such as blood circulation pipelines.
[0055] Optionally, in terms of the blood circulation pipeline, the installation component 200 can be a dust cap, a connector cap or other structures, or a protective cover such as a pressure sensor protective cover or other structures, all of which can be installed on the positioning component 100, with the help of the dual connection effect of thread and interference fit to increase the anti-fall-off performance.
[0056] Please continue to refer to Figure 2 In some embodiments, the rod portion 11 extends in the first direction, and the first matching portion 12 is located on the circumferential side of the rod portion 11. In the radial direction of the rod portion 11 perpendicular to the first direction, the outer diameter of the first matching portion 12 is larger than the outer diameter of the circumferential side.
[0057] In this embodiment, the first matching portion 12 achieves an interference fit with the mounting component 200 due to its larger outer diameter in the radial direction.
[0058] This interference fit not only strengthens the connection between the positioning component 100 and the mounting component 200, but also significantly improves the anti-detachment performance of the entire structure. When the first mating portion 12 is tightly engaged with the mounting component 200, any force attempting to disengage the mounting component 200 from the positioning component 100 will encounter greater resistance because the interference force generated by the interference fit needs to be overcome.
[0059] During actual use, when it is necessary to remove the mounting component 200 from the positioning component 100, the operator first needs to apply a certain force. This force must be large enough to overcome the friction and connection force generated by the interference fit between the first mating portion 12 and the mounting component 200. Once this force is successfully applied and overcomes the preset connection resistance, the mounting component 200 can begin to separate from the positioning component 100. The operator can then continue to perform the necessary screwing or other adjustments to complete the removal of the mounting component 200 or further installation process. This design ensures that the mounting component 200 can only be removed after a specific force is consciously applied, thereby greatly reducing the risk of it falling off due to misoperation or accidental circumstances.
[0060] Please continue to refer to Figure 2 In some embodiments, the rod portion 11 extends in the first direction, and the first matching portion 12 is located at the first end of the rod portion 11 in the first direction.
[0061] like Figure 2As shown, the first end of the rod 11 is the left end in the figure, and the first matching portion 12 is located at the left end of the rod 11. The second end of the rod 11 is the right end in the figure, and the right end of the rod 11 can be provided with other structures, such as a bolt head.
[0062] Please refer to Figure 4 , Figure 4 A schematic diagram of a positioning rod provided in the first embodiment of the present application.
[0063] like Figure 4 As shown, in some embodiments, in the circumferential direction of the rod 11 perpendicular to the first direction, the first end of the rod 11 is provided with a continuously extending ring body 111 extending in the circumferential direction, and the first matching portion 12 is provided on the continuously extending ring body 111.
[0064] In this embodiment, the design of the rod 11 is further enhanced by providing a continuously extending ring 111 in a circumferential direction perpendicular to the first direction. This not only provides additional structural support for the rod 11 but also creates an ideal platform for the placement of the first mating portion 12. The first mating portion 12 is positioned on the continuously extending ring 111. This arrangement enables the first mating portion 12 to perform its function more effectively.
[0065] The design of the continuously extending ring body 111 allows the first mating portion 12 to evenly distribute its retaining effect throughout the entire circumference. This helps to more evenly withstand and transmit force, reduce local stress concentration, and thus improve the durability and reliability of the positioning component 100. Furthermore, this arrangement of the first mating portion 12 also means that it can provide additional anti-slip performance through an interference fit during the connection process with the mounting component 200.
[0066] Please refer to Figure 5 , Figure 5 A schematic diagram of a positioning rod provided in the second embodiment of the present application.
[0067] like Figure 5 As shown, in the circumferential direction of the rod 11 perpendicular to the first direction, the first end of the rod 11 is provided with a plurality of extension monomers 112 spaced apart in the circumferential direction, and the first matching portion 12 is provided on the plurality of extension monomers 112 .
[0068] In this embodiment, the design of the rod 11 employs an innovative approach to optimize structure and performance. Rather than a continuous extended ring, the first end of the rod 11, along its circumference perpendicular to the first direction, is provided with a plurality of spaced-apart extended units 112. This design not only reduces material usage and overall weight, but also maintains sufficient structural strength and stability.
[0069] The first mating portions 12 are arranged on these extension monomers 112. This layout allows for effective positioning and restraint of the first mating portions 12 in the circumferential direction. Furthermore, the spacing of the extension monomers 112 reduces material requirements, thereby reducing weight. This design also helps lower production costs by reducing material consumption during the manufacturing process.
[0070] Furthermore, by spacing the extension units 112, the connection force between the first mating portion 12 and the mounting component 200 can be adjusted and controlled. This design allows for an appropriate interference fit without overly relying on material thickness, thereby maintaining connection strength while reducing the force required for installation and removal. This makes the connection and separation process easier while still ensuring sufficient anti-detachment performance.
[0071] Please refer to Figure 6 , Figure 6 A schematic diagram of a positioning rod provided in the third embodiment of the present application.
[0072] like Figure 6 As shown, in some embodiments, in the circumferential direction of the rod portion 11 perpendicular to the first direction, the first matching portion 12 includes a plurality of protrusion units 121 spaced apart along the circumferential direction at the first end of the rod portion 11 .
[0073] In this embodiment, the design of the rod portion 11 adopts an economical and efficient strategy, by providing a plurality of protruding units 121 at intervals on the continuously extended ring body 111 to form the first mating portion 12. This design approach directly responds to the needs of reducing material usage, reducing weight, and adjusting connection force.
[0074] The raised elements 121 are evenly spaced along the circumference, reducing material usage without sacrificing structural integrity. Because the raised elements 121 provide additional support and restraint only where needed, this design effectively reduces overall component weight, which is particularly important for portable or weight-sensitive applications.
[0075] At the same time, the design of the protrusions 121 allows for fine-tuning of the connection force between the first mating portion 12 and the mounting component 200. By controlling the size, shape, and spacing of the protrusions 121, the degree of interference fit can be precisely set, thereby achieving appropriate connection strength and anti-slip performance without over-reliance on material thickness.
[0076] Please continue to refer to Figures 4 to 6, taking the continuously extended ring body 111 and the annular first matching part 12 as the first solution, the extended monomer 112 and the protruding monomer 121 as the second solution, and the continuously extended ring body 111 and the protruding monomer 121 as the third solution, the connection strength between the positioning component 100 and the mounting component 200 is the first solution, the third solution and the second solution from high to low. Therefore, the anti-detachment strength of the first solution is the first, the anti-detachment strength of the third solution is the second, and the anti-detachment strength of the second solution is the last.
[0077] It should be noted that the circumferential direction of the rod portion 11 is perpendicular to the first direction, and the first matching portion 12 has various shapes in the cross section perpendicular to the circumferential direction to adapt to different application requirements and provide specific functional characteristics.
[0078] Optionally, the shape of the first matching portion 12 can be selected to be semicircular or triangular, and each shape has its own unique advantages and uses.
[0079] The semicircular cross-section of the first mating portion 12 provides a smooth profile, which helps reduce stress concentration when in contact with the mounting component 200 and also facilitates smooth sliding or rolling of the mounting component 200 along the edge of the first mating portion 12. The semicircular design may also help achieve smoother force distribution, thereby reducing local stress points during the connection process.
[0080] On the other hand, the triangular cross-section of the first mating portion 12 provides higher structural rigidity, which can provide additional stability in applications that need to bear large loads or in space constraints. The sharp apex of the triangle can serve as a positioning point to provide precise positioning and fixation, while its straight edges may help achieve more direct force transmission.
[0081] Please refer to Figure 7 , Figure 7 This is a schematic diagram of the movable part and the positioning rod provided in an embodiment of the present application when they are separated.
[0082] In some embodiments, the rod 11 is extended in the first direction; the positioning component 100 includes:
[0083] The fixing member 2 is fixedly sleeved on the rod portion 11 and is provided with a first thread structure 21;
[0084] The movable member 3 is movably sleeved on the rod portion 11. The movable member 3 can move along the first direction and rotate around the first direction. The movement range of the movable member 3 is limited by the first matching portion 12 and the fixed member 2. The movable member 3 is provided with a third thread structure 31;
[0085] Among them, the first thread structure 21 and the third thread structure 31 have consistent thread parameters; the fixed part 2 is provided with a fixed structure 22, and the movable part 3 is provided with a movable structure 32. Through the combination of the fixed structure 22 and the movable structure 32, the first thread structure 21 and the third thread structure 31 form a continuous thread.
[0086] In this embodiment, the design of the first engaging portion 12 serves a dual purpose. First, its larger radial outer diameter enables an interference fit with the mounting component 200. Second, the first engaging portion 12 continues to perform its primary function, namely, limiting the range of movement of the movable member 3 on the rod 11, ensuring that the movable member 3 does not exceed a predetermined position.
[0087] The positioning component 100 enhances the anti-falling performance through the innovative matching mechanism of the movable thread and the fixed thread, ensuring that the stability and security of the connection can be maintained even when affected by the external environment.
[0088] For example, the threaded connection of the mounting component 200 to the positioning component 100. During normal installation, the fixed structure 22 and the movable structure 32 combine to form a single unit, and the threads of the fixed component 2 and the movable component 3 are continuous. This means that the mounting component 200 can be installed on the positioning component 100 sequentially via the third thread structure 31 and the first thread structure 21.
[0089] Subsequently, when the external environment changes or other factors cause the installation component 200 to tend to fall off, even if the installation component 200 disengages and retreats from the first threaded structure 21 of the fixed component 2, it will not continue to disengage and retreat from the third threaded structure 31 of the movable component 3. This is because the movable component 3 can move freely on the rod 11, so the movable component 3 is separated from the combination with the fixed component 2, and the movable component 3 will move with the installation component 200. At this time, the movement range of the movable component 3 is limited, and the movable component 3 and the installation component 200 no longer rotate relative to each other, so the process of the installation component 200 disengaging and retreating on the movable component 3 is stopped, thereby avoiding the occurrence of falling off.
[0090] This mechanism effectively prevents the mounting member 200 from falling off, even when affected by the external environment, ensuring the stability and safety of the piping system. This innovative design significantly improves the reliability of key components in medical devices, reduces the risks associated with unstable connections, and provides safer and more reliable clinical operations.
[0091] When the fixed structure 22 and the movable structure 32 are connected, the fixed member 2 and the movable member 3 are in a coupled state. At this point, the threads are continuous, and the screwing and installation function of the mounting member 200 on the positioning member 100 can be performed normally. When the fixed structure 22 and the movable structure 32 are separated, the movable member 3 is disengaged from the fixed member 2. At this time, the threads are disconnected, which means that even if the mounting member 200 is threaded out of the fixed member 2, it will not be threaded out of the movable member 3 because the free movement of the movable member 3 on the rod 11 prevents the mounting member 200 from being screwed out of the movable member 3.
[0092] It should be noted that this embodiment does not limit how the fixed structure 22 and the movable structure 32 are combined. For example, the fixed structure 22 and the movable structure 32 can be combined by abutment, the fixed structure 22 and the movable structure 32 can be combined by snapping, or the fixed structure 22 and the movable structure 32 can be combined by interference fit. These are not limited in this embodiment and should all fall within the scope of description of this embodiment.
[0093] Please continue to refer to Figure 7 In some embodiments, the fixed structure 22 is a block 221 and the movable structure 32 is a notch 321. In the first direction of the rod 11 and in the circumferential direction perpendicular to the first direction, the block 221 and the notch 321 are matched with each other in a concave-convex manner.
[0094] In this embodiment, the fixed structure 22 and the movable structure 32 are connected by abutment. The fixed structure 22 is in the form of a block 221, while the movable structure 32 is designed as a notch 321. The block 221 and the notch 321 interact with each other on the rod 11 in a concave-convex fit. Specifically, the block 221 is located on the fixed member 2, while the notch 321 is located on the movable member 3. In the first direction of the rod 11, and in the circumferential direction perpendicular to the first direction, the block 221 and the notch 321 can also achieve a concave-convex fit.
[0095] This design allows for a consistent fit between the fixed member 2 and the movable member 3 in both the axial and circumferential directions, thereby enhancing the stability of the connection. The concave-convex fit between the block 221 and the notch 321 effectively restricts the movement of the movable member 3 on the rod 11, ensuring the stability and reliability of the positioning component 100 during operation. This design also facilitates rapid assembly and disassembly of the fixed member 2 and the movable member 3, improving the overall structure's practicality and ease of operation.
[0096] Please refer to Figure 8 , Figure 8 Schematic diagram of the distribution of the movable structure in the circumferential direction of the movable part provided in an embodiment of the present application.
[0097] like Figure 8 As shown, the distribution of the movable structure 32 on the movable part 3 is illustrated; in addition, the fixed structure 22 and the movable structure 32 have a corresponding positional relationship, so the distribution of the fixed structure 22 on the fixed part 2 is the same as that of the fixed structure 22 on the fixed part 2. Figure 8 The distribution is similar.
[0098] In some embodiments, the number of the fixed structure 22 and the movable structure 32 are both set to multiple;
[0099] In a circumferential direction of the fixing member 2 perpendicular to the first direction, the plurality of fixing structures 22 are evenly distributed at first intervals;
[0100] In a circumferential direction of the movable member 3 perpendicular to the first direction, the plurality of movable structures 32 are evenly distributed at second intervals;
[0101] The first interval and the second interval have a straight interval angle.
[0102] In this embodiment, the positioning component 100 is designed with multiple fixed structures 22 and movable structures 32 to improve its overall connection stability and adaptability. These structures are evenly distributed on the fixed part 2 and the movable part 3, respectively, along the circumferential direction perpendicular to the first direction.
[0103] Specifically, the fixed structures 22 are evenly distributed at a first interval on the fixed member 2, meaning the angles between each of the locking blocks 221 are the same. This design ensures that the fixed member 2 provides uniform support and locking points in the circumferential direction. Similarly, the movable structures 32 are evenly distributed at a second interval on the movable member 3, with each of the notches 321 also maintaining the same angular spacing, corresponding to the distribution of the fixed structures 22.
[0104] Importantly, the first and second intervals have consistent angles. This design feature ensures a consistent relationship between the fixed structure 22 and the movable structure 32, ensuring that no matter how the movable member 3 rotates, it can always find the matching fixed structure 22. This consistency not only improves the flexibility of the positioning component 100, but also enhances its connection reliability in multiple directions.
[0105] Optionally, Figure 8 There are four movable structures 32 in the embodiment, and the four movable structures 32 are evenly distributed on the movable part 3 at an interval of 90°; correspondingly, the four fixed structures 22 are evenly distributed on the fixed part 2 at an interval of 90°.
[0106] In some embodiments, the fixing member 2 and the positioning rod 1 are integrally formed.
[0107] In this embodiment, if Figure 7As shown, the movable part 3 can be regarded as one part, the fixed part 2 and the positioning rod 1 can be regarded as one part, and the movable part 3 is installed on the whole composed of the fixed part 2 and the positioning rod 1. The advantage of doing so is that the number of parts can be reduced, the difficulty of assembly can be reduced, and the cost can be controlled.
[0108] In addition, if the positioning rod 1 is regarded as a screw, it can be seen that there is a bolt head at the second end of the screw, that is, the right end. This application does not make any special limitations on the bolt head. That is to say, whether it is a bolt head integrally formed with the positioning rod 1 or a bolt head assembled separately from the positioning rod 1, it should all fall within the scope of description of this application.
[0109] In addition, the positioning rod 1 can be solid or hollow, and both should fall within the scope of the description of this application.
[0110] In some embodiments, the first thread structure 21 , the second thread structure 42 and the third thread structure 31 are double-thread helices.
[0111] In this embodiment, the double-thread helical design provides a tighter thread pitch and higher connection strength, while allowing for smoother screwing in and out. The double-thread helical design also helps to disperse force, reduce wear, and improve the overall durability and reliability of the positioning component 100 and the mounting component 200.
[0112] Alternatively, as Figure 3 As shown, the second matching portion 43 is a matching ring extending in the circumferential direction inside the mounting sleeve 4 .
[0113] In addition, the second fitting portion 43 can also adopt other forms. For example, the second fitting portion 43 adopts linear ribs extending in the first direction inside the mounting sleeve 4. The number of linear ribs is multiple, and the multiple linear ribs are distributed in the circumferential direction inside the mounting sleeve 4.
[0114] It should be noted that many of the components mentioned in this application are universal standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0115] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
[0116] The above is a detailed introduction to the installation components provided by the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
