The coarse adjustment component includes a coarse adjustment knob and a main valve stem. The coarse adjustment knob is a circular knob. The circular knob is connected to the control instrument housing via a bearing. The rotational damping force can be finely adjusted via an adjusting nut to ensure smooth rotation without free spin. A drive gear is fixedly mounted inside the coarse adjustment knob. A driven gear is fixedly mounted at one end of the main valve stem, meshing with the drive gear to form a 2:1 reduction ratio, so that 2 rotations of the coarse adjustment knob correspond to 1 rotation of the valve stem. The other end of the main valve stem is connected to a valve core. The valve core adopts a conical structure, which cooperates with the aforementioned air passage cavity to form a flow regulation channel. A valve stem rotation angle of 0-90° corresponds to a flow rate of 0-15L / min.

[0035] Optionally, the fine-tuning assembly includes a fine-tuning slip ring and a fixed internal gear ring. The fine-tuning slip ring is sleeved on the outside of the coarse-tuning knob. The fine-tuning slip ring slides axially relative to the coarse-tuning knob. Fine-tuning is achieved through a planetary gear set.

[0036] Optionally, the fine-tuning slip ring is an annular structure. A guide groove is provided on the inner ring of the fine-tuning slip ring. The guide groove engages with the guide boss of the coarse-tuning knob, enabling axial sliding. A planetary gear carrier is fixedly mounted on the inner side of the fine-tuning slip ring. Planetary gears are mounted on the planetary gear carrier. The fixed internal gear ring is fixed to the outer casing and meshes with the planetary gears. When the fine-tuning slip ring slides axially to the working position, the planetary gears simultaneously mesh with the fixed internal gear ring and the driven gear of the main valve stem, forming a 10:1 reduction ratio. At this time, rotating the fine-tuning slip ring one revolution results in only a 36° rotation of the main valve stem, corresponding to a flow rate adjustment range of 0.5 L / min, achieving precise fine-tuning.

[0037] Optionally, the fine-tuning assembly further includes a return spring. The return spring is sleeved inside the fine-tuning slip ring. When fine-tuning is not required, the return spring pushes the fine-tuning slip ring to reset. The planetary gear disengages from the driven gear. This prevents accidental activation that could affect the coarse-tuning parameters.

[0038] Optionally, the flow indicator module includes an indicator tube body and a float assembly. The indicator tube body is made of a light-transmitting material.

A honeycomb-shaped airflow stabilizing mesh is provided at the bottom of the indicator tube body. Guide ribs are provided axially on the inner wall of the indicator tube body. The float assembly includes a conical float. The conical float is disposed inside the indicator tube body. Under the action of airflow, the conical float slides up and down under the constraint of the guide ribs of the indicator tube body.

[0039] Optionally, the flow indicator module includes a linkage mechanism, an indicator dial, and a damping assembly. The linkage mechanism includes a primary linkage and a secondary linkage.

The accuracy of the dial and pointer engagement is ≤0.05 L / min. The damping assembly can be fitted onto the fixed axis of the pointer.

[0040] In the process of adopting technical solutions to address the aforementioned technical problems, the following technical problem often arises: Hospitalized patients often require transport in critical condition, at which point the vehicle travels at high speeds, making manual adjustment of oxygen flow rate less accurate. The conventional solution to this second technical problem is usually to pre-adjust the oxygen flow rate of the oxygen supply device or quickly adjust it when the vehicle stops en route. However, these conventional solutions still have the following drawbacks: In critical situations, the condition of the transported patient may change abruptly, requiring timely adjustments to the oxygen flow rate. Adjusting the flow rate only after the vehicle stops can negatively impact the patient's health.

[0041] Considering the problems with the conventional solutions mentioned above, and addressing the second technical issue—that hospitalized patients often require transport in critical condition, where vehicles travel at high speeds and the accuracy of manually adjusting oxygen flow is low—the following solution can be adopted based on the current technological situation: Optionally, the aforementioned flow-adjustable oxygen supply device for mobile devices may further include a main control module, an automatic flow adjustment module, a display and operation module, and a wireless communication module. The automatic flow adjustment module, display and operation module, pressure detection sensor, and wireless communication module are all communicatively connected to the main control module. The main control module can be a controller for processing pressure signals, executing flow adjustment algorithms, and driving various peripherals. For example, the main control module can be a microcontroller. The automatic flow adjustment module may include a drive module and a limit protection mechanism. The drive module can be a stepper motor. The output end of the stepper motor meshes with the driven gear of the main valve stem through a reduction gear. One rotation of the stepper motor corresponds to a 36° rotation of the main valve stem, with a flow adjustment range of 0.5 L / min, matching the adjustment accuracy of the fine-tuning slip ring. The limit protection mechanism can be a photoelectric limit switch. Photoelectric limit switches can be installed at both ends of the main valve stem to prevent over-rotation of the motor from causing valve core jamming, ensuring that the flow adjustment range is controlled within 0.1-15 L / min. The display and operation module can be a touch screen. The aforementioned touchscreen display can be used to display real-time blood oxygen saturation, pulse rate, flow rate, and oxygen source pressure. The touchscreen display may also include virtual flow rate adjustment buttons. The aforementioned wireless communication module can be used to transmit information with other external devices. As an example, the wireless communication module can receive body parameter information sent by various devices of the patient to adjust the oxygen flow rate. The wireless communication module can also receive oxygen flow rate adjustment information sent by other devices to adjust the oxygen flow rate. For example, a doctor in a hospital can remotely control the aforementioned flow-adjustable oxygen delivery device.

[0042] Optionally, the above-mentioned flow-adjustable oxygen supply device may also include a vibration sensor, which may be disposed on the outside of the control head housing.

[0043] Optionally, the aforementioned adjustable flow oxygen delivery device may also include a mechatronics separation mechanism. This mechatronics separation mechanism can be an electromagnetic clutch. In automatic mode, the electromagnetic clutch engages, and the motor drives the valve stem. In manual mode, the electromagnetic clutch disengages, the motor separates from the valve stem, and medical personnel can directly adjust the flow using the existing coarse adjustment knob / fine adjustment slip ring, with a switching time of ≤1 second.

[0044] Optionally, the main control module described above can be configured to perform the following steps: The first step is to obtain the oxygen pressure information detected by the pressure sensor mentioned above.

[0045] The second step is to generate the initial oxygen delivery flow rate based on the aforementioned oxygen pressure information and standard oxygen pressure information. In practice, the main control module can generate the initial oxygen delivery flow rate based on the aforementioned oxygen pressure information and standard oxygen pressure information by using a pre-set linear relationship between oxygen pressure and oxygen delivery flow rate. For example, the main control module can determine the initial oxygen delivery flow rate by multiplying the difference between the aforementioned oxygen pressure information and the standard oxygen pressure information by a preset pressure compensation coefficient. The preset pressure compensation coefficient can be 0.08 L / (min·MPa).

[0046] The third step is to control the aforementioned drive module to perform the oxygen supply operation according to the initial oxygen supply flow rate described above. In practice, the aforementioned drive module can supply oxygen according to the aforementioned initial oxygen supply flow rate.

[0047] The fourth step is to obtain the patient's physical parameter information sent by the monitoring device. This physical parameter information may include blood oxygen saturation.

[0048] The fifth step is to acquire the vibration information collected by the aforementioned vibration sensor. This vibration information can include vibration acceleration.

[0049] Step 6: Input the aforementioned blood oxygen saturation and vibration information into a pre-trained target oxygen delivery flow generation model to obtain the target oxygen delivery flow. The pre-trained target oxygen delivery flow generation model can be a machine learning model that takes blood oxygen saturation and vibration information as input and the target oxygen delivery flow as output. This model may include an input layer, a blood oxygen delivery flow generation layer, an anti-interference correction oxygen delivery flow generation layer, and an output layer. The input layer can be a feature extraction layer that extracts features from blood oxygen saturation and vibration information to obtain blood oxygen saturation feature information and vibration feature information. The blood oxygen delivery flow generation layer can be a classification layer that takes blood oxygen saturation feature information as input and blood oxygen delivery flow as output; for example, it may include a fully connected layer and an activation function layer. The anti-interference correction oxygen delivery flow generation layer can be a classification layer that takes vibration feature information and blood oxygen delivery flow as input and anti-interference correction oxygen delivery flow as output; for example, it may include a fully connected layer and an attention mechanism layer. The aforementioned output layer can determine the anti-interference corrected oxygen supply flow rate as the target oxygen supply flow rate for output.

[0050] Step 7: Following the target oxygen supply flow rate outlined above, control the aforementioned drive module to perform the oxygen supply flow rate adjustment operation. In practice, the drive module can supply oxygen according to the target oxygen supply flow rate.

[0051] The aforementioned content regarding automatic oxygen flow adjustment is an inventive point of this disclosure, solving technical problem two: "Hospitalized patients often require transport in critical condition, and at this time, the vehicle travels at high speed, resulting in low accuracy of manual oxygen flow adjustment." The reasons for low accuracy in oxygen flow adjustment are as follows: hospitalized patients often require transport in critical condition, and at this time, the vehicle travels at high speed, resulting in low accuracy of manual oxygen flow adjustment. Solving these factors can improve the accuracy of oxygen flow adjustment. To achieve this effect, the flow-adjustable oxygen supply device for mobile devices disclosed in this disclosure further includes a main control module, an automatic flow adjustment module, a display operation module, and a wireless communication module. The automatic flow adjustment module includes a drive module and a limit protection mechanism. The output end of the stepper motor meshes with the driven gear of the main valve stem through a reduction gear. One rotation of the stepper motor corresponds to a 36° rotation of the main valve stem, with a flow adjustment range of 0.5 L / min, matching the adjustment accuracy of the fine-tuning slip ring. The limit protection mechanism can be a photoelectric limit switch. Photoelectric limit switches can be installed at both ends of the main valve stem. The display operation module can be a touch screen. The aforementioned wireless communication module can be used to transmit information with other external devices. The aforementioned flow-adjustable oxygen delivery device also includes a vibration sensor, which is located outside the control unit housing. The aforementioned flow-adjustable oxygen delivery device also includes a mechanical-electronic separation mechanism. The mechanical-electronic separation mechanism is an electromagnetic clutch. In automatic mode, the electromagnetic clutch engages, and the motor drives the valve stem. In manual mode, the electromagnetic clutch disengages, and the motor disengages from the valve stem. The aforementioned main control module is configured to perform the following steps: acquire oxygen pressure information detected by the aforementioned pressure sensor; generate an initial oxygen delivery flow rate based on the aforementioned oxygen pressure information and standard oxygen pressure information; control the aforementioned drive module to perform oxygen delivery operation according to the aforementioned initial oxygen delivery flow rate; acquire body parameter information sent by the patient's body monitoring device. The aforementioned body parameter information may include blood oxygen saturation; acquire vibration information collected by the aforementioned vibration sensor; input the aforementioned blood oxygen saturation and the aforementioned vibration information into a pre-trained target oxygen delivery flow rate generation model to obtain the target oxygen delivery flow rate; control the aforementioned drive module to perform oxygen delivery flow rate adjustment operation according to the aforementioned target oxygen delivery flow rate. Therefore, the automatic flow rate adjustment module enables automatic adjustment of the oxygen supply flow rate, eliminating the need for manual adjustment and thus improving the accuracy of flow rate regulation. Furthermore, the mechanical-electronic separation mechanism allows for dual mechanical / electronic adjustment modes, ensuring uninterrupted oxygen supply in case of equipment failure, further enhancing oxygen delivery safety. Additionally, by dynamically compensating for pressure fluctuations and vibration interference based on the patient's blood oxygen saturation, the system precisely controls the oxygen supply flow rate, further improving the accuracy of flow rate regulation.

[0052] Optionally, the aforementioned flow-adjustable oxygen supply device may further include a main control module. The main control module may be a controller for processing pressure signals, executing flow regulation algorithms, and driving various peripherals. For example, the main control module may be a microcontroller. Both the pressure detection module and the flow regulation module are connected to the main control module. The main control module is configured to: The first step is to acquire the pressure information set collected by the pressure detection module over a certain period of time. Then, determine the average pressure value of each pressure data point in the set. In practice, this period can be 2 seconds.

[0053] The second step is to determine whether the average pressure value is less than or equal to a preset minimum pressure threshold. This preset minimum pressure threshold can be a pressure value that indicates insufficient oxygen supply (below or equal to this threshold). For example, the preset minimum pressure threshold could be 0.1 MPa.

[0054] The third step involves generating an oxygen anomaly message in response to the determination that the average pressure is less than or equal to the preset minimum pressure threshold. This oxygen anomaly message can be "Insufficient oxygen, please replenish promptly." In practice, in response to the determination that the average pressure is less than or equal to the preset minimum pressure threshold, the main control module can use a preset insufficient oxygen warning template as the oxygen anomaly message.

[0055] The fourth step is to determine whether the average pressure value is greater than or equal to a preset maximum pressure threshold. This preset maximum pressure threshold can be a pressure value representing the instantaneous increase in oxygen levels above or equal to that threshold. For example, the preset maximum pressure threshold could be 0.5 MPa.

[0056] Fifth, in response to determining that the average pressure is greater than or equal to the preset maximum pressure threshold, an oxygen flow rate too high alert message is generated. This message can be "Oxygen is being squeezed too fast, please slow down." In practice, in response to determining that the average pressure is greater than or equal to the preset maximum pressure threshold, the main control module can identify the preset oxygen flow rate too high alert template as an oxygen anomaly.

[0057] In the process of adopting technical solutions to address the aforementioned technical problems, the following technical problem three often arises: different transport scenarios require different oxygen supply and humidification methods, and simply using a single oxygen supply and humidification method results in poor patient comfort. The conventional solution to this technical problem three is generally to use different oxygen supply devices for different transport scenarios. However, this conventional solution still has the following drawback: the required types of oxygen supply devices are numerous and cumbersome.

[0058] Considering the problems with the conventional solutions mentioned above, and addressing the third technical issue—that different transport scenarios require different oxygen and humidification methods, and that simply using a single method results in poor patient comfort—the following solution can be adopted based on the current technological situation: Optionally, the aforementioned adjustable flow oxygen supply device may further include a temperature control module and a scene mode selection button group. The temperature control module can be a component for adjusting the oxygen supply temperature. For example, the temperature control module may include a heating and insulation sleeve. The heating and insulation sleeve can be fitted over the humidification bottle. The heating and insulation sleeve may include a sheath and a heating wire. The heating wire is wound around the inner layer of the sheath.

[0059] Optionally, the aforementioned scenario mode selection button group may include, but is not limited to, at least one of the following: a scenario mode selection button representing the neonatal / premature infant transport mode, a scenario mode selection button representing the adult critical care transport mode, and a scenario mode selection button representing the short-distance transport mode for mild cases. Different scenario modes correspond to different oxygen delivery standards. For example, the aforementioned neonatal / premature infant transport mode requires low-flow, precise oxygen delivery to avoid respiratory irritation. The flow rate adjustment range is 0.01-1 L / min. The relative humidity range is 44-55 mg / L. The temperature is 37℃.

[0060] Optionally, the aforementioned flow-adjustable oxygen supply device may further include a water storage tank and a peristaltic pump. The water storage tank supplies water to the humidification bottle via the peristaltic pump.

[0061] The main control module described above can also be configured to perform the following steps: The first step is to determine the scene mode based on the scene mode selection operation detected by any scene mode selection button.

[0062] The second step is to determine the oxygen delivery standard based on the aforementioned scenario mode. This standard may include the flow rate adjustment range, relative humidity range, and temperature range. In practice, the main control module can determine the oxygen delivery standard based on the scenario mode using a preset oxygen delivery standard matching table. For example, the main control module can filter the preset oxygen delivery standard corresponding to the scenario mode from the preset oxygen delivery standard matching table to obtain the oxygen delivery standard. As an example, the aforementioned neonatal / premature infant transport mode requires low-flow, precise oxygen delivery to avoid respiratory irritation. The flow rate adjustment range is 0.01-1 L / min. The relative humidity range is 44-55 mg / L. The temperature is 37℃.

In practice, the aforementioned drive module can supply oxygen within the aforementioned flow rate adjustment range. The aforementioned peristaltic pump can provide water within the aforementioned relative humidity range. The aforementioned heating insulation jacket can heat within the aforementioned temperature range.

[0064] The aforementioned content regarding different oxygen delivery standards for different scenario modes is an inventive point of this disclosure, solving technical problem three: "Different transport conditions require different oxygen delivery and humidification conditions; simply using a single oxygen delivery and humidification method results in poor patient comfort." The reasons for poor patient comfort are as follows: different transport conditions require different oxygen delivery and humidification conditions; simply using a single oxygen delivery and humidification method results in poor patient comfort. Solving these factors can improve patient comfort. To achieve this effect, the flow-adjustable oxygen delivery device for mobile devices disclosed herein optionally includes a temperature adjustment module and a scenario mode selection button group. The temperature adjustment module is a component for adjusting the oxygen delivery temperature. The temperature adjustment module includes a heating and insulation sleeve. The heating and insulation sleeve is fitted over the humidification bottle. The heating and insulation sleeve includes a covering and a heating wire. The heating wire is wound around the inner layer of the covering. The aforementioned scene mode selection button group includes, but is not limited to, at least one of the following: a scene mode selection button representing neonatal / premature infant transport mode, a scene mode selection button representing adult critical care transport mode, and a scene mode selection button representing short-distance transport mode for mild cases. Different scene modes correspond to different oxygen delivery standards. The aforementioned flow-adjustable oxygen delivery device also includes a water tank and a peristaltic pump. The water tank supplies water to the humidification bottle via the peristaltic pump. The aforementioned main control module can also be configured to perform the following steps: in response to detecting a selection operation of any scene mode selection button, determine the scene mode based on the selected scene mode button. Determine the oxygen delivery standard based on the scene mode. The oxygen delivery standard includes a flow rate adjustment range, a relative humidity range, and a temperature range. Based on the oxygen delivery standard, control the aforementioned drive module, the aforementioned peristaltic pump, and the aforementioned heating and insulation jacket to perform oxygen delivery operations. Thus, by having medical personnel select the corresponding oxygen delivery mode, and then determining the corresponding oxygen flow rate, oxygen humidity, and oxygen temperature based on the oxygen delivery mode, the various modules can be adjusted to provide suitable oxygen delivery conditions for the patient, thereby improving patient comfort.

[0065] The various embodiments disclosed above have the following beneficial effects: The flow-adjustable oxygen delivery device for mobile devices, through some embodiments of this disclosure, effectively combines and balances the oxygen bag, oxygen flow control meter, and humidification bottle, enabling oxygen adjustment during transport, thereby improving safety in use and patient transport. Specifically, the danger caused by personnel or oxygen bags falling is that during oxygen delivery in the ward, a ward management oxygen channel connects the oxygen flow meter and the oxygen humidification bottle to adjust the oxygen flow. Patients being transported are usually more seriously ill and require more precise oxygen delivery. During transport, due to environmental limitations, only oxygen bags are typically used. These oxygen bags can only replenish oxygen and cannot accurately adjust the oxygen flow; therefore, medical staff manually squeeze the oxygen bags during transport. Based on this, some embodiments of the present disclosure include an adjustable oxygen supply device for mobile devices, comprising an oxygen bag, an oxygen flow control meter, a humidification bottle, and a fixed support module. The oxygen bag, the oxygen flow control meter, and the humidification bottle are connected via connecting pipes. The oxygen bag is connected to the air inlet of the oxygen flow control meter, the air inlet of the humidification bottle is connected to the air outlet of the oxygen flow control meter, and the air outlet of the humidification bottle is used to connect to a nasal cannula. The oxygen flow control meter includes a control meter housing, a pressure detection module, a flow adjustment module, and a flow indication module. The control meter housing contains an air passage cavity and an adjustment mechanism. The device includes a regulating valve fixing slot and a pressure detection fixing slot. The gas path cavity is connected to the inlet and outlet of the oxygen flow control meter, respectively. The regulating valve fixing slot is located within the gas path cavity. The pressure detection module includes a pressure detection sensor, which is located within the pressure detection fixing slot. The flow regulation module includes a flow regulation valve and an adjustment knob. The flow regulation valve is installed within the regulating valve fixing slot and is used to regulate the oxygen flow. The flow indicator module displays the oxygen flow. The fixing support module secures the oxygen bag, the oxygen flow control meter, and the humidification bottle. Therefore, the flow-adjustable oxygen delivery device for mobile equipment can regulate the oxygen flow through the flow regulation module, and the fixing support module can secure the oxygen bag, the oxygen flow control meter, and the humidification bottle, thereby reducing the risk of personnel or the oxygen bag falling. Because the oxygen flow can be observed through the flow indicator module, and the oxygen flow can be adjusted through the flow regulation module, more precise oxygen delivery can be provided according to the patient's condition, improving patient safety. Therefore, the flow-adjustable oxygen delivery device for mobile devices through some embodiments of the present disclosure can improve safety in use and patient transport.
