For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0020] Example 1 Please refer to the following: Figure 1 and Figure 2 This embodiment provides a respiratory therapy device 10, including a main unit 11, an airway accessory assembly 14, a control assembly, several airway assemblies 12, and several control valves 13.

[0021] The main unit 11 is equipped with a fan 111 and also has multiple side plates 112, with mounting positions 113 provided on at least two of the side plates 112. The fan 111 serves as an airflow power source, providing airflow power to the respiratory therapy device 10. The multiple side plates 112 of the main unit 11 form the external frame of the entire device, giving the device good structural stability and facilitating the installation and fixation of internal components. The side plates 112 also serve as carriers for the mounting positions 113, supporting the airway accessory assembly 14.

[0022] Several air duct assemblies 12 are disposed within the main unit 11, and each air duct assembly 12 is connected to a fan 111. Each air duct assembly 12 includes an air inlet end 121 and an air outlet end 122. The air inlet end 121 is connected to the fan 111, and the air outlet ends 122 are respectively disposed on mounting positions 113. The arrangement of the air duct assemblies 12 allows the airflow generated from the fan 111 to flow to different mounting positions 113 along a preset path, achieving reasonable airflow distribution and providing a structural basis for the multi-directional air duct accessory assembly 14. In a preferred embodiment, the number of air duct assemblies 12 is set to two sets, with the air outlet ends 122 of the two sets of air duct assemblies 12 arranged at a 180° angle. This design allows the airflow to be output in two opposite directions, facilitating the simultaneous use of two different air duct accessory assemblies 14. In another preferred embodiment, the number of air duct assemblies 12 is set to three groups, and the air outlet ends 122 of the three groups of air duct assemblies 12 are set at a 90° angle. This design further increases the flexibility of the equipment and allows more air duct accessory assemblies 14 to be connected at the same time.

[0023] The air duct assembly 12 is also equipped with a heating component and a disinfection component. The heating component heats the gas flowing through the air duct, improving the patient's comfort when inhaling the gas, especially in winter, as it avoids the irritation of the respiratory tract by cold air; specifically, the heating component is a heating wire. The disinfection component sterilizes the gas flowing through the air duct, reducing the risk of pathogen transmission and improving the safety of treatment; specifically, the disinfection component is equipped with ultraviolet light-emitting devices, far-UVC light-emitting devices, heating and sterilization units, photocatalytic units, or replaceable antibacterial filter materials, etc.

[0024] Several control valves 13 are mounted one-to-one on several air duct assemblies 12. The control valves 13 are used to control the on / off state of the air duct assemblies 12. The control valves 13 can precisely adjust the on / off state of each air duct assembly 12, thereby providing a structural basis for mounting air duct accessory assemblies 14 on installation positions 113 in different locations as needed.

[0025] The airway accessory assembly 14 is installed in any of the mounting positions 113. The airway accessory assembly 14 includes a humidifier 141 or a breathing circuit tubing. The humidifier 141 can increase the humidity and temperature of the output gas to avoid irritation of the patient's airway by dry or cold gas; the breathing circuit tubing is used to deliver gas directly to the patient's respiratory system.

[0026] The control assembly is communicatively connected to the blower 111 and several control valves 13. The control assembly is responsible for controlling the operation of each component, including but not limited to adjusting the speed of the blower 111 according to treatment needs, and opening and closing the control valves 13 installed on the airway accessory assembly 14. The control assembly controls the control valve 13 of the corresponding airway assembly 12 to open only when the airway accessory assembly 14 is installed on the mounting position 113; that is, the control assembly controls the opening of the control valve 13 on the airway assembly 12 corresponding to the mounting position 113 where the airway accessory assembly 14 is installed, and also controls the closing of the control valve 13 on the airway assembly 12 corresponding to the mounting position 113 where the airway accessory assembly 14 is not installed. This ensures that only the airway assembly 12 with the airway accessory assembly 14 correctly installed will open, avoiding airflow waste and preventing potential safety hazards when the airway accessory assembly 14 is not connected.

[0027] The respiratory therapy device 10 also includes several assembly detection assemblies 16, each corresponding to a number of mounting positions 113 and airway accessory assemblies 14, used to detect whether an airway accessory assembly 14 is installed at a mounting position 113; each assembly detection assembly 16 is connected to a control assembly. The assembly detection assemblies 16 can monitor the installation status of the airway accessory assemblies 14 in real time. Once an airway accessory assembly 14 is detected to be installed or removed, a signal is immediately sent to the control assembly, which then controls the opening or closing of the corresponding control valve 13 accordingly. In a preferred embodiment, the assembly detection assembly 16 includes a Hall sensor component, which detects the presence of the airway accessory assembly 14 through changes in magnetic field. In another preferred embodiment, the assembly detection assembly 16 includes a photoelectric sensor component, which detects the presence of the airway accessory assembly 14 through light path obstruction. In yet another preferred embodiment, the assembly detection assembly 16 includes a radio frequency identification (RFID) sensor component, which detects the presence of the airway accessory assembly 14 through an RFID tag. In yet another preferred embodiment, the assembly detection assembly 16 includes a capacitive proximity sensor assembly that detects the presence of the airway accessory assembly 14 by means of capacitance changes.

[0028] Mounting position 113 includes an accessory sealing structure 17, through which the airway accessory assembly 14 and the airway assembly 12 are sealed together. The sealing structure ensures that airflow does not leak during transmission, maintaining the required air pressure and flow rate for treatment. In a preferred embodiment, the sealing structure is an interference fit sealing structure, achieving a seal through the elastic deformation of the material. In another preferred embodiment, the sealing structure is a clamp sealing structure, achieving a seal through the tightening action of the clamp. In yet another preferred embodiment, the sealing structure is a screw-on sealing structure, achieving a seal through threaded rotation and tightening.

[0029] The respiratory therapy device 10 also includes an accessory auxiliary fixing structure 18, which is disposed on the main unit 11 and the airway accessory assembly 14 to fix the airway accessory assembly 14 to the main unit 11. The accessory auxiliary fixing structure 18 enhances the connection stability between the airway accessory assembly 14 and the main unit 11, preventing the airway accessory assembly 14 from falling off due to external forces during use. In a preferred embodiment, the accessory auxiliary fixing structure 18 includes a buckle, which secures the airway accessory assembly 14 through its elastic locking action. In another preferred embodiment, the accessory auxiliary fixing structure 18 includes a bolt, which secures the airway accessory assembly 14 through its tightening action. In yet another preferred embodiment, the accessory auxiliary fixing structure 18 includes a magnetic fastener, which secures the airway accessory assembly 14 through magnetic attraction.

[0030] The respiratory therapy device 10 also includes an accessory identification component, which is located at the mounting position 113 and the airway accessory assembly 14. The accessory identification component can identify the type of the installed airway accessory assembly 14, such as distinguishing between a humidifier 141 and a breathing circuit tube. The control assembly automatically adjusts the corresponding operating parameters, such as the fan speed 111, according to the identification result to adapt to the operating requirements of different types of airway accessory assemblies 14.

[0031] The drag coefficients of several air duct assemblies 12 are set equally, so that the airflow resistance is the same regardless of which mounting position 113 is used, ensuring the consistency of the treatment effect, and also facilitating the precise control of airflow parameters by the control assembly.

[0032] Example 2 This embodiment provides a control method for a respiratory therapy device based on an embodiment of the present invention, including: Several assembly and testing assemblies are tested at several mounting positions to obtain several first target mounting positions with airway accessory assemblies assembled, and several second target mounting positions without airway accessory assemblies assembled. The assembly detection assembly can be one or more of a Hall sensor assembly, a photoelectric sensor assembly, a radio frequency identification (RFID) sensor assembly, or a capacitive proximity sensor assembly. When using a Hall sensor assembly, a magnetic material can be applied to the airway accessory assembly. When the airway accessory assembly is installed in the mounting position, the Hall sensor assembly can detect a change in the magnetic field, thus determining that the airway accessory assembly is installed in that mounting position. When using a photoelectric sensor assembly, the presence of the airway accessory assembly can be determined by detecting whether the optical path is blocked by the airway accessory assembly. When using an RFID sensor assembly, an RFID tag can be applied to the airway accessory assembly. The RFID sensor assembly determines whether the airway accessory assembly is installed in the mounting position by reading the RFID tag information. When using a capacitive proximity sensor assembly, the presence of the airway accessory assembly can be determined by detecting a change in capacitance.

[0033] Acquire a plurality of first target air duct assemblies connected to a plurality of first target mounting positions, and acquire a plurality of second target air duct assemblies connected to a plurality of second target mounting positions; Based on the obtained information about the first and second target mounting positions, the control assembly determines the air duct assemblies that correspond one-to-one with these mounting positions. Since the mounting positions and air duct assemblies are connected in a one-to-one correspondence, the first target air duct assembly corresponding to the first target mounting position and the second target air duct assembly corresponding to the second target mounting position can be directly determined.

[0034] Open the control valves on several first target air duct assemblies, close the control valves on several second target air duct assemblies, and start the fan to supply air to the user end.

[0035] The control assembly opens the control valve on the first target air duct assembly and simultaneously closes the control valve on the second target air duct assembly. When the fan is on, airflow can only flow through the first target air duct assembly to the first target mounting position equipped with the airway accessory assembly, and will not flow to the second target mounting position without the airway accessory assembly. This ensures that airflow only flows to the effective airway accessory assembly, avoiding airflow waste and leakage, and improving the working efficiency and therapeutic effect of the respiratory therapy equipment. It should be noted that multiple airway accessory assemblies can be installed on the main unit.

[0036] In a preferred embodiment, when the airway accessory assembly is a humidifier, the heating component in the airway assembly can heat the gas flowing through the humidifier to improve the humidification effect. When the airway accessory assembly is a breathing circuit pipe, the heating component in the airway assembly can heat the gas flowing through the breathing circuit pipe to prevent the gas from condensing in the pipe.

[0037] In another preferred embodiment, the disinfection component in the air duct assembly can disinfect the flowing gas, reducing the risk of infection for patients. The disinfection component can employ ultraviolet disinfection or other suitable disinfection methods.

[0038] In summary, this application provides a respiratory therapy device and its control method. The respiratory therapy device includes: a main unit equipped with a fan and having multiple side plates, with mounting positions provided on at least two of the side plates; a plurality of air duct assemblies disposed in the main unit and connected to the fan, with each mounting position corresponding to one of the air duct assemblies; a plurality of control valves mounted on each of the air duct assemblies, the control valves being used to control the on / off state of the air duct assemblies; an airway accessory assembly mounted on any of the mounting positions; and a control assembly communicatively connected to the fan and the plurality of control valves. The control assembly controls the control valve of the corresponding air duct assembly to open when and only when the airway accessory assembly is mounted on the mounting position. The respiratory therapy device features mounting positions on at least two side panels of the main unit. A fan is connected to each mounting position via several air duct assemblies, each with a control valve. The control assembly communicates with the fan and control valves, and the corresponding control valve opens only when an air duct accessory assembly is installed at the mounting position. This allows for changing the mounting position of air duct accessory assemblies without rotating the main unit or extending the tubing, reducing the risk of tubing bending and detachment. Unused sides remain closed, preventing bypass leaks and no-load ventilation, reducing noise and gas waste, maintaining stable flow and pressure, and improving bedside layout flexibility and maintenance efficiency.
