Description

Technical Field

[0001] This utility model belongs to the field of medical rehabilitation equipment technology, and in particular relates to a control device for a soft oxygen chamber. Background Technology

[0002] As a convenient medical rehabilitation device, oxygen chambers are widely used in homes, medical institutions, and other settings.

[0003] However, existing soft oxygen chamber control devices suffer from problems such as limited functionality, complex operation, and insufficient safety. For example, some devices lack automatic depressurization functions, which poses a risk of overpressure operation. Furthermore, the control of oxygen flow direction is not flexible enough when switching modes, which seriously affects the user experience.

[0004] Therefore, developing an integrated and intelligent soft oxygen chamber control device is of great practical significance. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a soft oxygen chamber control device that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a soft oxygen chamber control device, including a main unit casing and a controller located inside it. The controller includes a control motherboard and a button display board, and also includes a pressure relief valve, a nasal inhalation valve, and a function valve located on the top of the main unit casing. The pressure relief valve is connected to the oxygen chamber through a pipe and is used to automatically open and release pressure when the pressure inside the chamber is higher than a set pressure value. The nasal inhalation valve is connected to the oxygen chamber and the oxygen supply system through a pipe, and is opened in nasal inhalation mode and closed in oxygen chamber mode. The function valve is connected to the oxygen chamber and the nasal inhalation interface through a pipe and is used to control the pressure inside the chamber in oxygen chamber mode and change the oxygen flow direction when switching modes.

[0007] Preferably, the set pressure value is 0.1 bar.

[0008] Preferably, the pressure relief valve, the nasal suction valve, and the functional valve are all solenoid valves, and are electrically connected to the control main board through an electromagnetic control mechanism.

[0009] Preferably, the electromagnetic control mechanisms of the pressure relief valve, the nasal suction valve, and the functional valve are powered by DCV.

[0010] Preferably, the nasal inhalation valve remains open in nasal inhalation mode, allowing oxygen to be directly delivered to the nasal inhalation interface.

[0011] Preferably, the functional valve dynamically adjusts the start and stop of the oxygen generation system according to the pressure inside the oxygen chamber in oxygen chamber mode.

[0012] Preferably, the pressure relief valve, nasal suction valve, and functional valve are integrated and mounted in the same area on the top of the main unit housing via a bracket.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0014] First, the pressure relief valve automatically opens to relieve pressure when the pressure inside the chamber is too high, effectively preventing the risk of overpressure and ensuring user safety.

[0015] Secondly, the intelligent control of the nasal inhalation valve and the functional valve makes the oxygen flow direction switching more flexible and improves the user experience.

[0016] Finally, by integrating multiple functions such as depressurization, nasal inhalation, and functional control, intelligent and integrated control of the soft oxygen chamber is achieved. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0022] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0023] In the description of this utility model, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Reference Figure 1 The soft oxygen chamber control device includes a main housing 1 and a controller located inside it, and also includes a pressure relief valve 2, a nasal inhalation valve 3 and a function valve 4 located on the top of the main housing 1.

[0025] In the above technical solution, the controller includes a control motherboard and a button display board. The control motherboard is connected to an oxygen concentration sensor and a pressure sensor, and receives and processes signals from the oxygen concentration sensor, the pressure sensor, and the button display board. In oxygen chamber mode, the control motherboard monitors the oxygen concentration in the chamber in real time through the oxygen concentration sensor. When the concentration reaches the upper limit (which can be set via remote control) and is held for 10 seconds, the control function valve 4 starts working. After 20 seconds, the oxygen generation system solenoid valve stops. When the concentration is 5 percentage points lower than the upper limit (this difference can be adjusted via remote control), and is held for 10 seconds, the oxygen generation system solenoid valve restarts. After 5 seconds, the function valve 4 stops. The displayed oxygen concentration value is a correction value of 2% of the sensor value, with 2% being the default value, which can be adjusted via remote control. When the measured value is less than 21%, 21% is displayed.

[0026] The button display panel provides the user interface, which includes a timer button, a mode button, a pressure chamber button, and a power button. The specific layout is as follows: Figure 2 As shown.

[0027] The timer button increments the timer by 10 minutes with each touch. A long press allows for quick adjustment of the timer. The mode button switches between oxygen chamber and nasal inhalation modes, but this function is only available when the device is in standby mode. The pressure button allows for cyclical setting of the working pressure, ranging from 1.1 to 1.5 bar with an adjustment precision of 0.1 bar. The device plays a welcome voice when powered on, a safety prompt voice when starting up, and an end voice when powered off. In addition, corresponding voice feedback is provided for operations such as timer termination and pressure adjustment.

[0028] It should also be noted that the control motherboard implements multiple alarm functions:

[0029] When the power supply is interrupted, a power failure alarm is triggered, the fault indicator light flashes at a frequency of 2Hz and emits a pulse group sound;

[0030] When the oxygen generation system's operating current is greater than 7A or remains 0 for 15 seconds, a compressor fault alarm is triggered, displaying code E1.

[0031] A depressurization alarm is triggered and code E2 is displayed when the cabin pressure remains below the set value of 0.2 bar for 35 minutes.

[0032] A communication failure alarm is triggered when the oxygen concentration sensor communication is interrupted for 30 seconds, displaying code E4.

[0033] A low voltage alarm is triggered when the power supply voltage is below 185V for 15 seconds, displaying code E5. A high temperature alarm is triggered when the cabin temperature exceeds 46℃ for 30 seconds, displaying code E6.

[0034] Furthermore, the pressure relief valve 2, the nasal suction valve 3, and the functional valve 4 are all solenoid valves, and are electrically connected to the control main board through an electromagnetic control mechanism to achieve intelligent control.

[0035] During use, pressure relief valve 2 is connected to the oxygen chamber via a pipeline. When the pressure inside the oxygen chamber exceeds the set pressure by 0.1 bar, the electromagnetic control mechanism of pressure relief valve 2 will automatically open upon receiving a command from the main control board, releasing excess oxygen and reducing the pressure inside the chamber to a safe range, thus ensuring safe operation. Once the pressure inside the chamber drops to a safe range, pressure relief valve 2 automatically closes. This design is because traditional pressure relief devices may have problems such as slow response and inaccurate pressure control. This device uses an electromagnetic valve as pressure relief valve 2 and is electrically connected to the main control board through an electromagnetic control mechanism, achieving intelligent control. It can quickly and accurately respond to changes in the pressure inside the chamber and perform pressure relief operations in a timely manner, greatly improving the safety of use.

[0036] When in use, the nasal inhalation valve 3 is connected to the oxygen chamber and oxygen supply system via a pipeline. In nasal inhalation mode, the electromagnetic control mechanism of the nasal inhalation valve 3 receives instructions from the control motherboard and remains open, allowing oxygen to be directly delivered to the nasal inhalation interface to meet the user's nasal inhalation needs. In oxygen chamber mode, the electromagnetic control mechanism of the nasal inhalation valve 3 receives instructions from the control motherboard and closes, stopping the delivery of oxygen to the nasal inhalation interface. This design is because traditional nasal inhalation devices may not be able to flexibly switch the oxygen flow direction according to different usage modes, resulting in oxygen waste or inconvenience. However, the nasal inhalation valve 3 of this device, connected to the control motherboard through an electromagnetic control mechanism, can automatically switch the oxygen flow direction according to the working mode, realizing flexible control of the oxygen flow direction, improving oxygen utilization efficiency, and meeting the user's needs in different scenarios.

[0037] When in use, function valve 4 is connected to the oxygen chamber and nasal inhalation port via a pipeline. In oxygen chamber mode, function valve 4 dynamically adjusts the start and stop of the oxygen generation system based on the pressure sensor signal received by the control mainboard, thereby achieving precise control of the chamber pressure. When switching modes, function valve 4 changes the oxygen flow direction, causing oxygen to flow from the oxygen chamber to the nasal inhalation port or vice versa. This design is because traditional function valves may have a single function and cannot achieve flexible switching and precise control of multiple modes. However, function valve 4 of this device is connected to the control mainboard through an electromagnetic control mechanism, which not only enables precise control of the chamber pressure in oxygen chamber mode, but also flexibly changes the oxygen flow direction when switching modes, improving the functionality and adaptability of the device and meeting the diverse needs of users.

[0038] Considering that traditional equipment may use different power supply methods, resulting in problems such as unstable power supply and inaccurate electromagnetic control, this device adopts a unified DC12V power supply for the electromagnetic control mechanisms of pressure relief valve 2, nasal suction valve 3, and functional valve 4. This ensures the stable operation of the electromagnetic control mechanisms. At the same time, through the intelligent control of the main board, precise control of each valve is achieved, improving the reliability and stability of the device.

[0039] Considering that the components of traditional equipment are installed separately, resulting in a cumbersome installation and maintenance process that requires a lot of time and manpower, this device integrates the pressure relief valve 2, the nasal suction valve 3, and the function valve 4 in the same area on the top of the main unit housing 1 using a bracket. This facilitates installation and maintenance. During installation, the entire integrated module can be installed on the top of the main unit housing 1. During maintenance, each valve can be easily inspected, repaired, and replaced. This device adopts a bracket integration method, which centrally installs each valve in one area, greatly simplifying the installation and maintenance process, improving work efficiency, and reducing maintenance costs.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
