Description

Technical Field

[0001] This utility model belongs to the technical field of connector assembly and disassembly tools, specifically relating to an assembly and disassembly tool for medical gas terminal connectors. Background Technology

[0002] Medical gas supply systems are an indispensable critical infrastructure in modern hospitals, widely used to provide oxygen, compressed air, and negative pressure suction in wards, operating rooms, and other areas. The quick-connect terminals at the end of these systems are high-frequency, critical components that allow medical staff to quickly connect and disconnect various medical devices. Due to frequent plugging and unplugging and environmental factors, these terminals often experience problems such as aging seals and wear of internal parts, requiring timely maintenance and replacement.

[0003] During maintenance, it is often necessary to disassemble or install core moving components that are secured to valve seats by threads. However, existing maintenance tools and methods generally suffer from several insurmountable drawbacks when handling this delicate task. First, because the terminal connector is installed within the space-constrained equipment belt, conventional tools struggle to achieve precise alignment with the moving component. This alignment misalignment results in insufficient engagement between the tool and the disassembly latch (usually made of softer brass) on the moving component used to transmit torque. Consequently, when torque is applied, the tool experiences uneven force and is prone to slippage.

[0004] Secondly, slippage can have serious consequences. On the one hand, it can directly scratch or erode the brass jaws, causing minor cosmetic damage or even permanent deformation, making subsequent disassembly and assembly extremely difficult, and sometimes requiring destructive removal and replacement of the entire expensive terminal valve seat. On the other hand, unstable operation also significantly reduces maintenance efficiency and increases the workload and time costs for maintenance personnel. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a tool for disassembling and assembling medical gas terminal connectors.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A tool for disassembling and assembling a medical gas terminal connector is provided, comprising: A rod with an inlet and an operating end; A guide portion is provided at the inlet end of the rod and is coaxially arranged with the rod.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 As shown, the specific embodiments provided by this utility model are as follows: like Figures 1 to 2As shown in the figure, an embodiment of this utility model provides a tool for disassembling and assembling medical gas terminal connectors, aiming to solve the problems of inaccurate positioning, easy slippage, and damage to components in the prior art. The tool includes a rod 1, a guide part 2, a coupling part 3, and an abutment part 4.

[0021] Specifically, the rod 1 is the main structure of the tool, which is slender and rod-shaped, with an inlet end 101 close to the work target and an operating end 102 for the user to hold and exert force.

[0022] The guide part 2 is located at the inlet end 101 of the rod body 1 and is coaxial with the rod body 1. The function of the guide part 2 is to provide precise positioning and guidance. Its outer diameter can be smoothly inserted into the air inlet inside the medical gas terminal connector. Through a tight fit with the inner wall of the air inlet, the axis of the entire tool is aligned with the central axis of the terminal connector, thus providing a stable foundation for subsequent disassembly and assembly operations and effectively avoiding shaking caused by misalignment.

[0023] Specifically, the coupling part 3 is a working component that directly interacts with the disassembly bayonet inside the terminal connector to transmit torque, and it can engage with the shape of the disassembly bayonet. To ensure that the coupling part 3 forms a stable whole with the rod body 1 after installation, preventing loosening or detachment under high torque operation, this tool also has an abutment part 4. This abutment part 4 is screwed onto the rod body 1 by a threaded connection, so it can move forward or backward along the axial direction of the rod body 1 for position adjustment. After the coupling part 3 is installed, the operator can screw the abutment part 4 to move it axially until it engages with the rear end of the coupling part 3. This locking method can apply an effective axial preload, completely eliminating any potential gap between the coupling part 3 and the disassembly bayonet, so that the coupling part 3 is firmly locked to the disassembly bayonet, thereby ensuring the rigidity and stability of torque transmission and ensuring the safety and non-damage of disassembly and assembly operations.

[0024] In a preferred embodiment, in order to improve the grip comfort and ease of force application of the tool, the operating end 102 of the rod body 1 is provided with a hand handle 7.

[0025] The hand lever 7 is perpendicular to or horizontally positioned on the main axis of the lever body 1, and its configuration can be a T-shaped handle, an L-shaped handle, or a similar force-saving structure. By adding this hand lever 7, a lever arm is formed, providing the user with a mechanical leverage advantage.

[0026] When performing disassembly or installation work, especially when applying significant torque to loosen or tighten components to ensure a seal, the user can easily grip the handle 7 for rotational operations. Compared to directly gripping the slender rod 1, the handle 7 not only provides a more comfortable and stable grip but also makes applying torque more effortless and controllable, thereby reducing operational intensity and improving work efficiency and operational safety.

[0027] In this embodiment, a mounting slot 6 is provided at the inlet end 101 of the rod body 1, and its opening direction is open from the side or bottom of the rod body 1.

[0028] Based on this, the operator can easily push or snap the coupling part 3 directly into the mounting slot 6 from the side or bottom of the rod body 1 in a horizontal manner.

[0029] Preferably, the coupling part 3 can be inserted into the mounting slot 6 from the side, in which case it is not necessary to disassemble the guide part 2. Alternatively, the guide part 2 can be disassembled first, and then the coupling part 3 can be inserted into the mounting slot 6 from the bottom, and then the guide part 2 can be installed.

[0030] This side- or bottom-insertion installation method greatly simplifies the process of replacing the coupling part 3. When it is necessary to replace the coupling part 3 of different specifications according to different maintenance tasks, the operator does not need to completely pull back or even remove the locking abutment part 4. It may be possible to simply loosen it slightly to quickly remove the old coupling part 3 from the side and replace it with the new coupling part 3. This reduces the number of operation steps and time, especially in scenarios where frequent replacements are required, greatly improving the convenience and overall efficiency of the work.

[0031] In a preferred embodiment, the mounting slot 6 includes an inlet area 601 with a relatively large slot width and a limiting area 602 with a relatively small slot width that is connected thereto.

[0032] This embodiment is suitable for installing the coupling part 3 directly from the side. Specifically, first, the operator aligns the coupling part 3 with the wider inlet area 601 of the slot and inserts it into the slot. Then, the operator only needs to move the coupling part 3 a short distance along the axial direction of the rod 1 so that it slides into the narrower limiting area 602 of the slot.

[0033] Once the coupling part 3 enters the limiting region 602, it is effectively initially limited by the limiting region 602 because the width of the groove in the limiting region 602 is approximately equal to the size of the coupling part 3. In this state, the operator can operate the abutment part 4 to move it forward and engage it with the initially fixed coupling part 3 between the abutment part 4 and the guide part 2.

[0034] like Figure 3As shown, more specifically, the coupling part 3 consists of a base 301 and a winglet group 302.

[0035] The base 301 is the basic platform of the coupling part 3, which can be directly inserted and installed from the mounting slot 6 of the rod 1, and its two sides are used to connect the blade assembly 302.

[0036] The vane assembly 302 is a functional component that directly engages with the disassembly bayonet to transmit torque. The vane assembly 302 is also detachably connected to the base 301. To achieve functional flexibility and wide applicability, the vane assembly 302 is not composed of a single-specification component, but rather includes multiple vanes that differ in thickness and / or length.

[0037] Therefore, users can select one or more suitable blades from a variety of different specifications based on the actual width and depth of the internal bayonet 401 of the terminal connector to be repaired, and install them on both sides of the base 301. This on-demand combination method allows the tool to flexibly match various sizes of bayonet 401, whether standard, non-standard, or worn due to long-term use, achieving near-zero clearance engagement. This not only fundamentally eliminates the risk of slippage and component damage caused by size mismatch, but also greatly improves the tool's versatility and professionalism.

[0038] Specifically, mounting holes with internal threads are respectively provided on both sides of the base 301, which are the positions for mounting the winglets.

[0039] Accordingly, each replaceable blade has a connecting rod with external threads on one side (i.e., the end connected to the base 301). The thread specification of the connecting rod matches the internal thread of the mounting hole on the base 301.

[0040] During assembly, the user simply aligns the connecting rod on the winglet with the mounting hole on the base 301 and screws it on to securely mount the winglet onto the base 301. This threaded connection provides strong axial locking force and radial stability, ensuring that the winglet maintains a stable integrated structure with the base 301 even when subjected to enormous shear forces.

[0041] like Figure 4 As shown, in a preferred embodiment, the abutment portion 4 is specifically a sleeve that can be easily gripped by the user. The inner wall of the sleeve is threaded, which can engage with the corresponding thread on the outer wall of the rod 1, thereby realizing the screwing of the sleeve on the rod 1 and the adjustment of its position along the axial direction of the rod 1.

[0042] Furthermore, the end of the sleeve facing the base 301 forms a bayonet 401 with a specific concave-convex geometry. Correspondingly, the rear end of the base 301 also has a bayonet 401 structure that matches the sleeve bayonet 401.

[0043] Therefore, after the operator installs the base 301 in place, they only need to screw the sleeve forward. When the sleeve's locking jaws 401 and the base 301's locking jaws 401 approach each other, a small preset angle is rotated circumferentially to achieve rapid engagement and locking between the two locking jaws 401. This locking jaw 401 connection method, compared to simple end-face contact, provides more reliable mechanical limiting and effectively prevents the coupling part 3 from loosening when subjected to reverse torque.

[0044] In a preferred embodiment, the guide portion 2 is composed of a connecting seat 201 and a guide head 202.

[0045] The connecting seat 201 serves as an intermediate component for connection. One end of it can be detachably connected to the guide end 101 of the rod body 1, for example, through threads or snap-fit. The other end is used to connect to the guide head 202.

[0046] The guide head 202 is a component that directly contacts the air inlet of the terminal connector and performs the guiding function. It is also detachably connected to the connecting seat 201.

[0047] Furthermore, the guide head 202 in this embodiment is made of an elastic material or has an elastic structure. When the tool is inserted into an air inlet that is slightly deformed, elliptical, or axially misaligned, this elastic guide head 202 can produce adaptive minor deformation, thereby smoothly guiding and gently aligning the tool to the center. This not only avoids jamming or secondary damage to the inner wall of the port that may be caused by the forced insertion of rigid components, but also provides the operator with a gentler tactile feedback, greatly improving the compatibility and safety of the tool in complex and non-ideal maintenance scenarios.

[0048] In a preferred embodiment, the guide portion 2 integrates an illumination structure 5.

[0049] The lighting structure 5 can be flexibly set at different positions on the guide section 2 according to specific needs. For example, it can be set on the connector 201 and guide the light to the front end through the light guide element; or, more directly, miniaturized lighting elements (such as LED beads) can be directly integrated into the inside or front end of the guide head 202.

[0050] By adding this lighting structure 5, the tool provides unobstructed direct illumination for maintenance personnel when inserting the terminal connector. This allows the operator to clearly observe the specific condition of the internal air vents and disassembly bayonets of the terminal connector, greatly improving visibility whether in poorly lit environments such as inside equipment belts or in scenarios requiring detailed inspection of the port's interior. This not only reduces the difficulty of alignment operations and improves work efficiency, but also enables the tool to function as an endoscopic inspection light before performing disassembly or assembly tasks, helping maintenance personnel to pre-diagnose whether there are foreign objects or damage to the port, thereby achieving more precise and safer maintenance operations.

[0051] In a preferred embodiment, the detachable guide head 202 is not of a single specification, but is equipped with multiple sets of spare parts of different specifications. For example, the diameter and / or length of each set of guide heads 202 are different.

[0052] Before performing maintenance work, the user can select the most suitable guide head 202 from multiple sets of guide heads for installation based on the actual situation of the terminal to be maintained, whether it is the standard inner diameter of its air inlet or the depth of its internal structure.

[0053] This method of selecting the optimal size guide head 202 on demand not only ensures that the tool can be adapted to most mainstream or non-mainstream terminal connectors, but also achieves the best initial alignment accuracy and stability in every specific maintenance task.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
