Description

Technical Field

[0001] This application belongs to the field of respiratory therapy equipment technology, specifically relating to a suspension component and a respiratory therapy device. Background Technology

[0002] Ventilators and other respiratory therapy equipment are commonly used in medical and home care to provide patients with continuous ventilation. Traditional respiratory therapy equipment is typically designed as a vertical or tabletop device, requiring placement on a stable surface such as a desktop or bedside table to ensure stable operation. However, in actual clinical and home care scenarios, patients often face space constraints or insufficient facilities. For example, when there is no tabletop of suitable height next to the bed, the equipment must be placed on the ground, making the control panel difficult to reach and increasing the risk of tubing kinking. In the confined space of a home bedroom or temporary medical facilities, traditional placement methods may also affect the equipment's heat dissipation efficiency and patient safety.

[0003] To address the placement issue, existing technologies have proposed using external supports or hooks to assist in securing respiratory therapy equipment. However, these solutions have the following drawbacks: external accessories require separate storage and are cumbersome to install, lacking convenience in emergency situations; furthermore, external supports or hooks are typically integrated with the device body, protruding from the casing when not in use, affecting aesthetics and potentially causing damage from impacts; and most solutions do not consider the device's center of gravity balance, making it prone to tilting due to unilateral force after suspension, affecting the operational stability of the internal fan components. Furthermore, respiratory therapy equipment often needs to be moved between different locations, and existing fixing methods struggle to balance quick assembly / disassembly with structural sealing, potentially leading to loosening of the suspension components or dust entering the device after prolonged use. Utility Model Content

[0004] This application provides a suspension component and a respiratory therapy device for use in respiratory therapy equipment, in order to solve the technical problems of traditional respiratory therapy equipment being inconvenient to place in certain usage environments, unable to achieve quick placement and storage, and having poor suspension stability in some suspendable devices.

[0005] The technical solution adopted in this application is as follows:

[0006] A suspension assembly for a respiratory therapy device includes a fixing member and a suspension member. The fixing member is detachably mounted to the respiratory therapy device. The suspension member has a rotating portion and a suspension portion connected to the rotating portion. The rotating portion is rotatably mounted to the fixing member so that the suspension portion has a storage position close to the respiratory therapy device and a suspension position away from the respiratory therapy device. When the suspension portion is in the suspension position, it can engage with an external support structure to suspend the respiratory therapy device.

[0007] The suspension assembly described in this application also includes the following additional technical features:

[0008] The number of suspension components is two, and the fixing component has two mounting positions for installing the suspension components. The two mounting positions are symmetrically arranged with respect to the vertical plane where the center of gravity of the respiratory therapy device is located.

[0009] The suspension part includes a straight segment and a curved segment connected to each other. The straight segment extends from the rotating part and is coaxial with the rotating part. The curved segment has a recessed opening. The suspension part rotates about the axis of the rotating part to switch between a storage position and a suspension position.

[0010] The fastener includes a fixing plate and a fastening block. The fastening block has a rotating through hole. The fastening block is fixedly connected to the fixing plate. The rotating part is rotatably inserted into the rotating through hole.

[0011] The bottom of the rotating part is provided with a limiting piece, and the radial cross-sectional dimension of the limiting piece and the straight segment is larger than the radial cross-sectional dimension of the rotating through hole to restrict the rotating part from dislodging from the rotating through hole.

[0012] The fixing plate is bent away from the respiratory therapy device at the mounting position, and the fastening block is connected to the fixing plate by bolts.

[0013] The suspension assembly also includes a housing, which has a receiving cavity. The rotating part and the fixing member are located in the receiving cavity, and the housing has a through hole for the suspension part to extend out.

[0014] The fixing member is detachably connected to the respiratory therapy device via a mounting rod. The housing has a mounting groove, and the end of the mounting rod is located in the mounting groove. The suspension assembly also includes a flexible sealing member, which is movably installed on the housing and can expose or cover the mounting groove.

[0015] The flexible sealing element has a sealing ring rib on its outer ring that abuts against the inner wall of the mounting groove.

[0016] The outer casing is provided with a socket and a buckle on both sides of the mounting groove. The flexible sealing member is provided with a plug rod at the corresponding socket and a locking platform at the corresponding buckle. The plug rod is located inside the socket, and the buckle engages with the locking platform.

[0017] It also includes a flexible sealing gasket connected to the fixing member, wherein when the fixing member is fixed to the respiratory therapy device, the flexible sealing gasket is located between the fixing member and the respiratory therapy device.

[0018] This application also provides a respiratory therapy device, which includes a housing and an air duct assembly disposed inside the housing. The side wall of the housing has a mounting hole for replaceably mounting the suspension assembly or the shielding plate; wherein the suspension assembly is selected from the suspension assemblies described above.

[0019] The respiratory therapy device described in this application also includes the following additional technical features:

[0020] The housing contains a mounting plate, and the fastener is bolted to the mounting plate via bolts passing through the mounting holes. Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0021] 1. The suspension assembly of this application includes a fixing member and a hanging member, wherein the hanging member includes a rotating part and a suspension part, and is installed on the respiratory therapy device through the fixing member. The suspension assembly, through its rotatable hanging member design, allows the respiratory therapy device to be flexibly hung on non-planar support structures such as bed railings and wall hooks, enabling the respiratory therapy device to be suspended in a suitable position in environments where placement is not feasible, thus increasing user convenience. Furthermore, the rotating part is rotatably mounted on the fixed component. By rotating the rotating part, the suspension part can be switched between the storage position and the suspension position. On the one hand, when it is necessary to hang the respiratory therapy equipment, rotating the rotating part outward will move the suspension part to the suspension position separated from the equipment. Since the suspension part is separated from the equipment, the probability of wear and interference from the equipment caused by the suspension points such as railings and hooks is reduced. This helps to maintain the integrity of the outer surface of the equipment and reduces the interference of the external environment on the respiratory therapy equipment, thereby improving the working stability of the respiratory therapy equipment. On the other hand, when the equipment is finished and needs to be stored, rotating the rotating part to the storage position will bring the suspension part close to the equipment, reducing the space occupied by the respiratory therapy equipment and facilitating the handling and storage of the respiratory therapy equipment. At the same time, the proximity of the suspension part to the respiratory therapy equipment can reduce the probability of the suspension part being touched by external objects and damaged during handling or storage, which helps to increase the average service life of the suspension component.

[0022] Furthermore, the fasteners are detachably installed on the respiratory therapy equipment, allowing users to easily disassemble the suspension components for maintenance or inspection, thus improving the user experience. Additionally, since each user's usage scenario may differ, the type of suspension unit can be adjusted by changing the suspension components. For example, users can choose a suspension unit with a hook structure or a magnetic suspension unit, increasing user options. Moreover, for users who do not require suspension, such as those who regularly place the respiratory therapy equipment on their bedside table, the suspension components can be removed to further reduce the space occupied by the equipment. When the usage environment changes and the user requires suspension, the fasteners can then be used to reattach the suspension components to the respiratory therapy equipment, meeting diverse user needs.

[0023] 2. As a preferred embodiment of this application, the dual suspension components increase the suspension stability of the suspension assembly. Since the internal fan of the respiratory therapy device vibrates during operation, single-point suspension may amplify the vibration amplitude. The dual suspension components are symmetrically distributed around the center of gravity of the respiratory therapy device, decomposing the vibration load from the fan into two opposing forces that cancel each other out, significantly reducing the swaying amplitude of the respiratory therapy device during operation. Furthermore, the dual suspension components reduce the stress on individual suspension components, decreasing the likelihood of stress concentration in the suspension section during long-term suspension. Simultaneously, the symmetrical layout of the dual suspension components allows the respiratory therapy device to maintain a horizontal posture during suspension, reducing the probability of internal pipe bending due to device tilting and liquid leakage due to tank tilting. Moreover, the dual suspension components significantly reduce the probability of the respiratory therapy device accidentally becoming unstable and falling. If a single suspension component is unable to provide suspension force due to external forces or other unforeseen circumstances, the other suspension component can still provide temporary support, buying time for emergency response. This redundancy design is crucial for life-saving medical equipment.

[0024] 3. In a preferred embodiment of this application, the straight segment and the rotating part extend coaxially, so that when the respiratory therapy device is suspended, the weight of the respiratory therapy device is transmitted to the rotating part through the straight segment, reducing the probability of instability caused by torque transmission misalignment and ensuring stable suspension of the respiratory therapy device. Simultaneously, the coaxial design of the straight segment and the rotating part ensures smooth switching between the storage and suspension positions of the suspension component, enabling rapid switching of the suspension assembly. The downward-curving concave design of the curved segment can adapt to most usage environments of the respiratory therapy device. For example, the suspension component can adapt well to bed railings of different diameters, as well as the railings of common wrought iron bed heads or bed frames in homes.

[0025] 4. In a preferred embodiment of this application, the housing of the suspension assembly provides a accommodating space for the rotating part. Dust accumulation and liquid splashing are common phenomena in the use of respiratory therapy equipment. By completely enclosing the rotating part and the fixing components within the housing, contaminants are effectively prevented from entering the mechanism. This effectively prevents the accumulation of dust and debris in the rotating part, reducing the cleaning burden on the suspension assembly. Furthermore, the airtightness of the housing is particularly important in hospital wards where frequent disinfection is required, effectively preventing disinfectant from seeping into the interior and corroding precision components. In addition, the housing provides shielding for the rotating part and fixing components within the accommodating cavity, preventing them from being exposed to the user's view and improving the user's viewing experience. Moreover, the housing also provides some protection for the rotating and fixing components, especially during the handling of the respiratory therapy equipment, as the fixing components and rotating part protrude outwards from the equipment and are easily subject to impact; the housing provides protection for them.

[0026] 5. As a preferred embodiment of this application, the design of the detachable connection between the fixing component and the respiratory therapy device facilitates the user's inspection and cleaning of the fixing component and suspension component after removal. Simultaneously, the mounting groove provides space for the mounting rod, facilitating its installation and assembly, and reducing the assembly pressure on the suspension assembly. Furthermore, after the fixing component is installed, the end of the mounting rod is located within the mounting groove, which is sealed by a flexible sealing component, effectively concealing the fixing component and mounting rod. This achieves a concealed layout of some components of the suspension assembly, helping to optimize the user's visual experience while reducing interference from the external environment on the fixing component, rotating parts, and mounting rod, thus optimizing the structural design of the suspension assembly.

[0061] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0062] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0066] As a preferred embodiment of this application, such as Figure 1 , Figure 2 As shown, a suspension assembly for a respiratory therapy device includes a fixing member 1 and a suspension member 2. The fixing member 1 can be detachably installed on the respiratory therapy device 7. The suspension member 2 has a rotating part 21 and a suspension part 22 connected to the rotating part 21. The rotating part 21 is rotatably installed on the fixing member 1 so that the suspension part 22 has a storage position close to the respiratory therapy device 7 and a suspension position away from the respiratory therapy device 7. When the suspension part 22 is in the suspension position, it can engage with an external support structure to suspend the respiratory therapy device 7.

[0067] The suspension assembly of this application includes a fixing member 1 and a suspension member 2. The suspension member 2 includes a rotating part 21 and a hanging part 22, and is installed on the respiratory therapy device 7 via the fixing member 1. The rotatable suspension member 2 design allows the respiratory therapy device 7 to be flexibly hung on non-planar support structures such as bed railings and wall hooks, enabling the respiratory therapy device 7 to be suspended in a suitable position even in environments lacking suitable placement conditions, thus increasing user convenience. Furthermore, the rotating part 21 is rotatably mounted on the fixing part 1. By rotating the rotating part 21, the suspension part 22 can be switched between the storage position and the suspension position. On the one hand, when it is necessary to hang the respiratory therapy device 7, the rotating part 21 can be rotated outward to move the suspension part 22 to the suspension position separated from the device. Since the suspension part 22 is separated from the device, the probability of wear and interference from the device caused by the suspension points such as railings and hooks is reduced. This helps to maintain the integrity of the outer surface of the device and reduces the interference of the external environment on the respiratory therapy device 7, thereby improving the working stability of the respiratory therapy device 7. On the other hand, when the device is finished and needs to be stored, the rotating part 21 is rotated to the storage position, and the suspension part 22 is close to the device, which reduces the space occupied by the respiratory therapy device 7 and facilitates the handling and storage of the respiratory therapy device 7. At the same time, the proximity of the suspension part 22 to the respiratory therapy device 7 can reduce the probability of the respiratory therapy device 7 being touched by external objects and damaged during handling or storage, which helps to improve the average service life of the suspension assembly.

[0068] Furthermore, the fastener 1 is detachably installed on the respiratory therapy device 7, facilitating the user's removal of the suspension assembly for maintenance or inspection, thus improving the user experience. Simultaneously, since each user's usage scenario may differ, the type of suspension part 22 can be adjusted by replacing the suspension part 2. For example, users can choose a suspension part 22 with a hook structure or a magnetic structure, increasing user options. Moreover, for users without suspension needs, such as those who regularly place the respiratory therapy device 7 on their bedside table, the suspension assembly can be removed to further reduce the space occupied by the respiratory therapy device 7. When the usage environment changes and the user requires suspension, the fastener 1 can be used to install the suspension part 2 on the respiratory therapy device 7, meeting the diverse usage needs of users.

[0069] This application does not limit the connection method between the fastener 1 and the respiratory therapy device 7. It can also be that the fastener 1 and the respiratory therapy device 7 are connected in a non-detachable manner by welding or by integrally forming the fastener 1 with the outer shell 4 of the respiratory therapy device 7.

[0070] As a preferred embodiment of this application, such as Figure 3As shown, there are two suspension components 2, and the fixing component 1 has two mounting positions for installing the suspension components 2. The two mounting positions are symmetrically arranged in the vertical plane where the center of gravity of the respiratory therapy device 7 is located.

[0071] Figure 3 The dashed line indicates the vertical plane where the center of gravity of the respiratory therapy device 7 is located. The dual suspension components 2 increase the suspension stability of the suspension assembly. Since the internal fan of the respiratory therapy device 7 vibrates during operation, a single-point suspension may amplify the vibration amplitude. The dual suspension components 2 are symmetrically distributed around the center of gravity of the respiratory therapy device 7, which decomposes the vibration load during fan operation into two forces in opposite directions. After these forces cancel each other out, the sway amplitude of the respiratory therapy device 7 during operation is significantly reduced. Furthermore, the dual suspension components 2 reduce the force on a single suspension component 2, reducing the possibility of stress concentration in the suspension section 22 under long-term suspension. Simultaneously, the symmetrical layout of the dual suspension components 2 allows the respiratory therapy device 7 to maintain a horizontal posture during suspension, reducing the probability of internal pipe bending caused by the tilt of the respiratory therapy device 7 and liquid leakage caused by the tilt of the water tank. Furthermore, the dual suspension components 2 significantly reduce the probability of the respiratory therapy device accidentally becoming unstable and falling. If a single suspension component 2 is subjected to external force or fails to provide suspension force due to other factors, the other suspension component 2 can still provide temporary support, giving users time for emergency treatment. This redundant design is crucial for life-related medical equipment.

[0072] The fastener 1 has two mounting positions, which allows a single fastener 1 to connect two suspension components 2 at the same time, thus reducing the manufacturing cost of the suspension assembly.

[0073] Specifically, both the fixing component 1 and the suspension component 2 are metal parts to ensure strength and improve the stress reliability of the suspension assembly.

[0074] This embodiment does not limit the structural form of the suspension part 22, which can be any of the following embodiments:

[0075] Example 1: As Figure 1 As shown, the suspension part 22 includes a straight section 221 and a curved section 222 connected to each other. The straight section 221 extends from the rotating part 21 and is coaxial with the rotating part 21. The curved section 222 has a recessed opening. The suspension part 22 rotates about the axis of the rotating part 21 to switch between a storage position and a suspension position.

[0076] The straight segment 221 extends coaxially with the rotating part 21, so that when the respiratory therapy device 7 is suspended, the weight of the respiratory therapy device 7 is transmitted to the rotating part 21 through the straight segment 221, reducing the probability of unstable suspension of the respiratory therapy device 7 due to torque transmission misalignment, and ensuring stable suspension of the respiratory therapy device 7. At the same time, the coaxial design of the straight segment 221 and the rotating part 21 ensures the smooth switching of the suspension part 22 between the storage position and the suspension position, realizing rapid switching of the suspension components. The downward concave design of the curved segment 222 can adapt to most usage environments of the respiratory therapy device 7. For example, the suspension part 22 can adapt well to bed railings of different diameters, as well as the railings of wrought iron bed heads, headboards, or bed frames commonly found in homes.

[0077] Example 2: The suspension unit includes interconnected straight segments and magnetic segments. The straight segments extend from the rotating part, and the magnetic segments are magnetic components. The suspension unit in this example is suitable for suspending a respiratory therapy device on a ferrous target object, relying on the magnetic attraction between the magnetic segments and the target object to maintain the suspension unit's stability. While the application range of this example is relatively small, it is suitable for target objects without obvious protrusions or depressions for mounting, such as flat ferrous bed heads where the suspension unit is difficult to mount. In such cases, the magnetic attraction of the magnetic segments can be used to mount the suspension assembly.

[0078] Example 3: The suspension unit includes an interconnected straight section and a snap-fit ​​section, with the straight section extending from the rotating part. The snap-fit ​​section has an outwardly protruding snap-fit ​​connector, suitable for a target suspension object specially designed for this suspension unit. The suspension object needs to have a snap-fit ​​groove, into which the snap-fit ​​connector is inserted to suspend the suspension assembly.

[0079] As a preferred example of the following embodiments, such as Figure 2 As shown, the fastener 1 includes a fixing plate 11 and a fastening block 12. The fastening block 12 is provided with a rotating through hole 121. The fastening block 12 is fixedly connected to the fixing plate 11, and the rotating part 21 is rotatably inserted into the rotating through hole 121.

[0080] The separate design of the fixing plate 11 and the fastening block 12 allows for adjustment of the size of the rotating through hole 121 according to design needs, accommodating rotating parts 21 of different sizes, which helps optimize the structural design of the suspension assembly. Preferably, the fastening block 12 can be a metal or plastic part, and the diameter of the rotating through hole 121 is slightly smaller than the size of the rotating part 21, so that the rotating part 21 has a certain damping feel during rotation, and when the suspension part 22 is in the storage position, the rotating part 21 is not easily rotated by external forces.

[0081] Preferably, such as Figure 11 As shown, the fastening block 12 is connected to the fixing plate 11 by bolts 120.

[0082] As a preferred method in this example, such as Figure 2 As shown, the bottom of the rotating part 21 is provided with a limiting piece 3. The radial cross-sectional dimension of the limiting piece 3 and the straight section 221 is larger than the radial cross-sectional dimension of the rotating through hole 121 to restrict the rotating part 21 from coming out of the rotating through hole 121.

[0083] The limiting piece 3 provides an anti-disengagement function for the rotating part 21, restricting its vertical displacement to prevent it from moving upwards and disengaging from the rotating through hole 121 under external force, thus ensuring the rotational stability of the rotating part 21. Preferably, the portion of the rotating part 21 above the rotating through hole 121 is larger than the diameter of the rotating through hole 121, thereby enabling upward and downward displacement of the rotating part 21 in the vertical direction.

[0084] Furthermore, such as Figure 2 As shown, the fixing plate 11 is bent away from the respiratory therapy device 7 at the mounting position, and the fastening block 12 is connected to the fixing plate 11 by bolts. The bending of the fixing plate 11 at the mounting position provides a certain installation space between the fixing plate 11 and the respiratory therapy device 7, thereby providing operating space during assembly, and also providing space for the bolts connecting the fastening block 12 and the fixing plate 11 to pass through, reducing the probability of the bolts interfering with the outer shell 4 of the respiratory therapy device 7 after passing through. At the same time, the detachable design of the fastening block 12 and the fixing plate 11 allows the rotating part 21 to be placed in the rotating through hole 121 first, and then the fastening block 12 to be fastened to the fixing plate 11 during assembly, reducing the assembly difficulty of the suspension part 2.

[0085] As a preferred embodiment of this application, such as Figure 4 , Figure 5 , Figure 10 , Figure 11 As shown, the suspension assembly also includes a housing 4, which has a receiving cavity 45 inside. The rotating part 21 and the fixing member 1 are located inside the receiving cavity 45. The housing 4 has a through hole 41 for the suspension part 22 to extend out.

[0086] The outer casing 4 of the suspension assembly provides a space for the rotating part 21. During the use of the respiratory therapy device 7, dust accumulation and liquid splashing are common occurrences. By completely enclosing the rotating part 21 and the fixing member 1 within the outer casing 4, moisture and contaminants are effectively prevented from entering the mechanism. This effectively prevents dust and debris from accumulating in the rotating part 21, reducing the cleaning burden on the suspension assembly. Furthermore, the airtightness of the outer casing 4 is particularly important in hospital wards where frequent disinfection is required, effectively preventing disinfectant from seeping into the interior and corroding precision components. In addition, the outer casing 4 provides shielding for the rotating part 21 and the fixing member 1 within the accommodating cavity 45, preventing them from being exposed to the user's view and improving the user's viewing experience. Moreover, the outer casing 4 also provides some protection for the rotating part 21 and the fixing member, especially during the handling of the respiratory therapy device 7, as the fixing member 1 and the rotating part 21 protrude outwards from the device and are easily subject to impact; the outer casing 4 provides protection for them.

[0087] As a preferred embodiment of this implementation, such as Figure 5 , Figure 6 , Figure 10 , Figure 11 As shown, the fixing component 1 is detachably connected to the respiratory therapy device 7 via a mounting rod 10. The outer casing 4 has a mounting groove 42, and the end of the mounting rod 10 is located within the mounting groove 42. The suspension assembly also includes a flexible sealing component 5, which is movably installed on the outer casing 4 and can expose or cover the mounting groove 42. The detachable connection between the fixing component 1 and the respiratory therapy device 7 facilitates the user's inspection and cleaning of the fixing component 1 and the suspension component 2 after removing the fixing component 1. At the same time, the mounting groove 42 provides space for the mounting rod 10, facilitating the installation and assembly of the mounting rod 10 and reducing the assembly pressure of the suspension assembly. Furthermore, after the fixing component 1 is installed, the end of the mounting rod 10 is located in the mounting groove 42, and the mounting groove 42 is sealed by the flexible sealing component 5, which can seal the mounting groove 42 and prevent external moisture from entering the mounting groove 42 and then entering the interior of the respiratory therapy device 7, thus ensuring the waterproof performance of the device. In addition, the flexible sealing component 5 has a shielding effect on the fixing component 1 and the mounting rod 10, realizing the concealed layout of some components of the suspension assembly. This helps to optimize the user's visual experience while reducing the interference of the external environment on components such as the fixing component 1, the rotating part 21, and the mounting rod 10, thus optimizing the structural design of the suspension assembly.

[0088] Preferably, the mounting rod 10 is a bolt.

[0089] As a preferred example in this embodiment, such as Figure 10 , Figure 11As shown, the outer casing 4 has a first through hole 190 and the fixing plate 11 has a second through hole 200. The mounting rod 10 passes through the first through hole 190 and the second through hole 200 in sequence, and passes through the side wall of the respiratory therapy device 7, thereby installing the suspension assembly to the respiratory therapy device 7.

[0090] As a preferred example in this embodiment, such as Figure 10 , Figure 11 , Figure 12 As shown, a portion of the outer casing 4 is recessed towards the side near the respiratory therapy device 7, forming a mounting groove 42. A positioning post 170 is also provided within the mounting groove 42 of the outer casing 4. A first positioning hole 140 is provided on the fixing plate 11, and a second positioning hole 150 is provided on the side wall of the respiratory therapy device. When the outer casing 4 is assembled onto the fixing plate 11, the positioning post 170 and the first positioning hole 140 cooperate to achieve positioning of the outer casing 4 and the fixing plate 11, thereby aligning the first through hole 190 with the second through hole 200 and achieving accurate installation of the mounting rod 10. Furthermore, when the suspension assembly is installed onto the respiratory therapy device 7, the positioning post 170 and the second positioning hole 150 cooperate to achieve positioning of the suspension assembly and the respiratory therapy device 7, thereby ensuring accurate installation of the mounting rod 10 onto the respiratory therapy device 7.

[0091] As a preferred example in this embodiment, such as Figure 7 As shown, the flexible sealing element 5 has a sealing ring rib 51 on its outer ring that abuts against the inner wall of the mounting groove 42. By setting the sealing ring rib 51, the sealing performance of the mounting groove 42 is increased, making it difficult for external moisture, dust, debris, etc. to enter the interior of the mounting groove 42 through the gap between the flexible sealing element 5 and the outer shell 4. This improves the protective effect of the outer shell 4 on the internal components and ensures the waterproof performance of the respiratory therapy device 7. At the same time, it can strengthen the bonding strength between the flexible sealing element 5 and the outer shell 4, preventing the flexible sealing element 5 from warping relative to the outer shell 4.

[0092] In addition, when the respiratory therapy device 7 is suspended to a support device such as a hospital bed via the suspension assembly, the outer surface of the flexible sealing member 5 of the suspension assembly can abut against the support device, which can play a buffering role and thus protect the respiratory therapy device 7.

[0093] Preferably, the flexible sealing element 5 and the sealing ring rib 51 are rubber parts.

[0094] As another preferred example under this embodiment, such as Figure 6 , Figure 7 As shown, the outer casing 4 has an insertion port 43 and a buckle 44 on both sides of the mounting groove 42. The flexible sealing component 5 has a plug rod 52 at the corresponding insertion port 43 and a locking platform 53 at the corresponding buckle 44. The plug rod 52 is located inside the insertion port 43, and the buckle 44 and the locking platform 53 are engaged.

[0095] This design increases the stability of the connection between the flexible sealing element 5 and the outer shell 4. The stable installation of the flexible sealing element 5 and the outer shell 4 is achieved through the cooperation of the socket 43 and the connecting rod 52, and the buckle 44 and the locking platform 53. Furthermore, when it is necessary to open the flexible sealing element 5 to install or remove the mounting rod 10 in the mounting slot 42, only outward force needs to be applied to the end of the corresponding connecting rod 52 of the flexible sealing element 5 to pull the connecting rod 52 out of the socket 43. Due to the deformability of the flexible sealing element 5, the buckle 44 and the locking platform 53 remain engaged. One end of the flexible sealing element 5 is connected to the outer shell 4, while the other end is lifted. After the user installs or removes the mounting rod 10, the flexible sealing element 5 is then snapped back together, eliminating the need for the user to completely remove the flexible sealing element 5 and then perform the repositioning installation, thus improving user convenience.

[0096] As a preferred embodiment of this application, such as Figure 11 As shown, the suspension assembly also includes a flexible sealing gasket 110 connected to the fixing member 1. When the fixing member 1 is fixed to the respiratory therapy device 7, the flexible sealing gasket 110 is located between the fixing member 1 and the respiratory therapy device 7. Preferably, the flexible sealing gasket 110 is located in the bending area of ​​the fixing plate 11.

[0097] The flexible sealing gasket 110 enhances the sealing performance of the respiratory therapy device 7, preventing dust, debris, and moisture from entering the device through the gap between the fastener 1 and the device. This provides stability for the internal components and ensures the device's waterproof performance. Furthermore, since the respiratory therapy device 7 operates with a fan, which generates vibrations that cause minor vibrations, the flexible sealing gasket 110 reduces these vibrations to some extent, minimizing the relative vibration between the device and the suspension assembly and improving the suspension stability of the device.

[0098] like Figure 8 , Figure 12 , Figure 13 As shown, this application also provides a respiratory therapy device 7, which includes a housing 6 and an air duct assembly disposed inside the housing 6. The side wall of the housing 6 is provided with a mounting hole 61 for replaceably mounting a suspension assembly or a shielding plate 130; wherein, the suspension assembly is selected from the suspension assemblies described above.

[0099] The respiratory therapy device 7 of this application can be stably suspended on the target object by the suspension assembly, and has strong adaptability to most scenarios. The mounting hole 61 provides installation space for the suspension assembly, and the suspension assembly and respiratory therapy device 7 are detachable and equipped with a shielding plate 130 to enhance adaptability to users with different needs. For some users who do not require suspension, the suspension assembly can be removed and the mounting hole 61 can be covered with the shielding plate 130 to meet the user experience of different users.

[0100] As one implementation method, such as Figure 12 As shown, the main unit of the respiratory therapy device 7 has a mounting position 180 on its side wall. The mounting position 180 has a second positioning hole 150 and a mounting hole 160. When the suspension assembly is installed on the respiratory therapy device 7, the flexible sealing gasket 110 of the suspension assembly abuts against the mounting position 180 to seal the periphery of the second positioning hole 150 and the mounting hole 160. When water droplets fall between the suspension assembly and the side wall of the respiratory therapy device 7, the presence of the flexible sealing gasket 110 can prevent water from entering the device from the second positioning hole 150 and the mounting hole 160, thereby ensuring the waterproof performance of the device.

[0101] As one implementation method, such as Figure 13 As shown, the shielding plate 130 has waterproof ribs 1301 on its periphery. When the shielding plate 130 is installed on the respiratory therapy device 7, the lower waterproof rib 1301 has a water leakage notch 1302. When water droplets penetrate between the shielding plate 130 and the respiratory therapy device 7, the water droplets can leak out through the water leakage notch 1302, while ensuring the assembly strength of the shielding plate 130. In addition, the inner side of the shielding plate 130 has a snap-fit ​​protrusion 1303, which is used to snap into the second positioning hole 150 and the mounting hole 160 to fix the shielding plate 130 to the respiratory therapy device 7. The snap-fit ​​protrusion 1303 has a stop rib structure, and the stop rib interface is embedded in the second positioning hole 150 and the mounting hole 160 of the respiratory therapy device 7, further improving the waterproof effect and preventing water from flowing into the main unit. When it is necessary to replace the shielding plate 130 with a suspension assembly, it can be pried out of the main unit of the respiratory therapy device 7 using a tool such as a flathead screwdriver from the groove of the shielding plate 130.

[0102] It should be noted that, Figure 13 The image shows two opposing views of the shielding plate 130, with the inner surfaces of the shielding plate 130 facing each other to show its front and back construction.

[0103] Preferably, such as Figure 9 As shown, the housing 6 has an internal mounting plate 9, and the fastener 1 is bolted to the mounting plate 9 by bolts passing through the mounting hole 61.

[0104] The mounting plate 9 provides a mounting platform for the fastener 1. Compared to mounting the fastener 1 directly onto the housing 6 of the respiratory therapy device 7, mounting it onto the mounting plate 9 improves the installation stability of the fastener 1 and reduces the stress on the housing 6 of the respiratory therapy device 7, preventing damage to the housing 6 due to stress concentration. Furthermore, the fastener 1 and the mounting plate 9 are detachably connected, facilitating the removal of the suspension assembly for maintenance and replacement, thus improving the user experience.
