[0059] The respiratory assistance device, for example, a humidifier, is a common medical device, which is usually used with a breathing machine, an anesthesia machine and the like through a connecting pipeline, for warming and humidifying the medical gas generated by the above-mentioned devices, and has been widely applied in emergency, general ward, operating room and the like. Referring to Figure 1The application example of connecting the humidifier to the breathing machine, the humidifier 1 is connected to the breathing machine 3 through the short pipe 2, specifically, the inhalation end 31 of the breathing machine 3 is connected to the water tank 11 of the humidifier 1 through the short pipe 2. The water tank 11 of the humidifier 1 is provided with a water injection port 112, and the water injection port 112 can be connected to a syringe or an infusion device, and the sterilized water is added to the water tank 11 of the humidifier 1 through the water injection port 112. The gas outlet 113 of the water tank 11 of the humidifier 1 is connected to one end of the inhalation branch 4, the other end of the inhalation branch 4 is connected to the Y-shaped three-way pipe 5, and one end of the exhalation branch 6 is connected to the Y-shaped three-way pipe 5, and the other end of the exhalation branch 6 is connected to the exhalation end 32 of the breathing machine 3. In the running state, the humidifier 1 heats the water in the water tank 11, so that the gas flow generated by the breathing machine 3 is transmitted from the inhalation end 31 to the water tank 11 of the humidifier 1, and is heated and humidified in the water tank 11, so that the gas flow output from the gas outlet 113 of the water tank 11 is heated and humidified. The gas flow is transmitted to the patient through the inhalation branch 4, and the exhalation of the patient after inhaling is transported to the exhalation end 32 of the breathing machine 3 through the exhalation branch 6 and then discharged.

[0060] In addition, Figure 1 The cable C in the figure represents the cable for temperature detection, the cable D represents the cable for heating the pipeline, E represents the inhalation branch heating joint, F represents the temperature probe at the outlet of the water tank, and G represents the temperature probe at the end of the Y-shaped three-way pipe.

[0061] At present, the first pipeline connecting the breathing auxiliary device and the patient, that is, Figure 1 The inhalation branch 4 in the figure contains two types of non-heating pipeline and heating pipeline. Among them, the non-heating pipeline only simply realizes the transmission of gas flow, and the heating pipeline is provided with heating devices such as heating guide wire inside, which can realize the heating of the gas flow in the first pipeline, thereby reducing the influence of the ambient temperature on the gas flow in the first pipeline, and maintaining the temperature and humidity of the gas flow reaching the patient end. Therefore, based on the above two types of pipelines, the breathing auxiliary device can operate in two working modes, including non-heating pipeline mode and heating pipeline mode. When the breathing auxiliary device operates in the non-heating pipeline mode, the breathing auxiliary device only heats the water tank through the heating disc, and when the breathing auxiliary device operates in the heating pipeline mode, the breathing auxiliary device not only heats the water tank through the heating disc, but also heats the heating guide wire inside the heating pipeline through the heating cable.

[0062] In actual application, the non-heating pipeline or the heating pipeline can be selected according to the requirement for use on the breathing assistance device. However, in the related art, when the breathing assistance device switches the operation mode, for example, switches from the non-heating pipeline mode to the heating pipeline mode or switches from the heating pipeline mode to the non-heating pipeline mode, the medical personnel need to operate the breathing assistance device, the learning cost of the operation mode is high, and the operation delay caused by human factors may occur, which affects the switching efficiency of the operation mode of the breathing assistance device.

[0063] Therefore, in the breathing assistance device provided by the embodiments of the present application, the controller detects the electrical connection of the plurality of cables connected to the plurality of electrical interfaces and / or the first pipeline of the breathing assistance device. According to the detected electrical connection, the controller controls the operation mode of the breathing assistance device, including the heating pipeline mode and the non-heating pipeline mode, or the controller provides an entry for controlling the operation mode of the breathing assistance device corresponding to the electrical connection. In addition, the controller selectively outputs alarm information for indicating the abnormal connection of the cables based on the detected electrical connection. Based on the above scheme, the automatic control of the operation mode of the breathing assistance device can be realized, the switching of the operation mode can be automatically realized, or the entry for switching the operation mode can be automatically provided to prompt the medical personnel to perform the relevant operation in time, the learning cost of the operation mode of the breathing assistance device is reduced, the operation delay caused by human factors is avoided, and the switching efficiency of the operation mode of the breathing assistance device is effectively improved.

[0064] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0065] Figure 2 The structure of the breathing assistance device provided by the embodiments of the present application is shown in the schematic diagram, referring to Figure 2 The breathing assistance device is used for heating and humidifying the gas flow delivered to the user, and includes:

[0066] The humidifier unit 21 has an inlet port and an outlet port. The humidifier unit 21 is used for receiving the gas flow through the inlet port and discharging the heated and humidified gas flow through the outlet port. The humidifier unit 21 is also used to be connected to the first pipeline, which is the heating pipeline or the non-heating pipeline.

[0067] The heating module 22 is used to provide heat energy to the humidifier unit 21 to heat the water in the humidifier unit 22.

[0068] The housing 23 comprises a plurality of electrical interfaces.

[0069] The control Figure 1 The application example further understands that the humidifier unit 21 corresponds to Figure 1 The water tank 11, the inlet port, i.e., the air inlet 111 of the water tank 11, the outlet port, i.e., the air outlet 113 of the water tank 11, the first pipeline, i.e., the suction branch 4, the heating module, i.e., the heating disc, for heating the water in the water tank 11.

[0070] In addition, in combination with Figure 1 The application example is based on Figure 2 The structure of the respiratory assistance device shown, the outlet port of the humidifier unit 21 is connected to the air inlet of the first pipeline, the inlet port of the humidifier unit 21 is connected to the air outlet of the second pipeline, and the air outlet of the first pipeline is connected to the patient; wherein the air inlet of the second pipeline is used to be connected to the breathing machine to deliver the gas flow output by the breathing machine to the humidifier 21.

[0071] In the embodiment of the present application, the respiratory assistance device can operate in a heated pipeline mode or a non-heated pipeline mode. When the respiratory assistance device operates in the heated pipeline mode and the first pipeline is a heated pipeline, the respiratory assistance device provides heat energy to the heating guide wire inside the first pipeline through the electrically connected first cable to heat the gas flow circulating in the first pipeline, and the temperature sensor inside the first pipeline is in communication connection with the second cable to monitor the temperature inside the first pipeline.

[0072] When the respiratory assistance device operates in the non-heated pipeline mode and the first pipeline is a heated pipeline, the first cable and the second cable are not electrically connected, the heating guide wire inside the first pipeline does not generate heat energy, and since the first pipeline only serves as a physical channel for transmitting the gas flow in the non-heated pipeline mode, the gas flow in the first pipeline does not need to be temperature detected, therefore, the temperature sensor inside the first pipeline is not in communication connection with the respiratory assistance device.

[0073] In the embodiment of the present application, the respiratory assistance device further comprises a controller 24, which is used to:

[0074] Detect the electrical connection of the plurality of cables with the plurality of electrical interfaces and / or the first pipeline; wherein the plurality of cables comprises a first cable for heating the pipeline and a second cable for temperature detection; the electrical connection includes all electrical connections or partial electrical connections or all non-electrical connections;

[0075] Based on the electrical connection, control the operation mode of the respiratory assistance device, or provide an entry corresponding to the electrical connection for controlling the operation mode of the respiratory assistance device; the operation mode includes a heated pipeline mode and a non-heated pipeline mode;

[0076] Here, the plurality of cables for which the controller 24 monitors the electrical connection status are cables related to the function of the breathing assistance device heating the first conduit in the heating conduit mode, i.e. a first cable for heating the conduit and a second cable for temperature detection. In an embodiment, the plurality of cables for which the controller 24 monitors the electrical connection status comprises:

[0077] a first cable and a second cable for electrical connection with the plurality of electrical interfaces; and / or,

[0078] a first cable and two second cables for connection with the first conduit, wherein the temperature probes of the two second cables are proximate to the gas inlet end and the gas outlet end of the first conduit, respectively.

[0079] When the breathing assistance device operates in the heating conduit mode, the breathing assistance device provides heat energy to the heating wire inside the first conduit through the electrically connected first cable for heating the conduit, wherein the first cable for heating the conduit comprises a first cable connected with the corresponding electrical interface on the housing of the breathing assistance device, such as the cable 7 in Figure 1 , and a first cable connected with the first conduit, such as the cable 8 in Figure 1 , so that the breathing assistance device transmits electric current to the heating wire through the cable 7 and the cable 8, the electric current passes through the heating wire, the heating wire generates heat, thereby converting electric energy into heat energy. In addition, the breathing assistance device measures the temperature inside the first conduit through the electrically connected second cable for temperature detection, wherein the second cable for temperature detection comprises a second cable connected with the corresponding electrical interface on the housing of the breathing assistance device, such as the cable 9 in Figure 1 , and two second cables, the temperature probes of the two second cables are proximate to the gas inlet end and the gas outlet end of the first conduit, respectively, so as to realize temperature monitoring of the gas flow in the first conduit by monitoring the temperature of the gas inlet end and the temperature of the gas outlet end of the first conduit.

[0080] In addition, in the embodiments of the present application, the controller 24 is further configured to selectively output alarm information indicating cable connection abnormalities based on the electrical connection status.

[0081] Hereinafter, the schemes of the controller controlling the operation mode of the breathing assistance device, the controller providing an entry corresponding to the electrical connection status for controlling the operation mode of the breathing assistance device, and the controller selectively outputting alarm information indicating cable connection abnormalities based on the electrical connection status are described in detail.

[0082] In an embodiment, the operation mode of the breathing assistance device is controlled based on the electrical connection status, comprising:

[0083] When the electrical connection status is all electrical connection, the breathing assistance device is controlled to operate in the heating conduit mode.

[0084] As a case of the automatic control operation mode of the breathing assistance device, regardless of whether the breathing assistance device is in the state of just starting up or in operation, once the controller detects that the electrical connections of the above-mentioned multiple cables are all electrically connected, the controller controls the breathing assistance device to operate in the heating pipeline mode. At this time, if the breathing assistance device is operating in the non-heating pipeline mode, the controller controls the breathing assistance device to switch the operation mode from the non-heating pipeline mode to the heating pipeline mode; if the breathing assistance device is operating in the heating pipeline mode, the controller controls the breathing assistance device to maintain the operation of the heating pipeline mode; if the breathing assistance device has just been turned on, then after the initialization of each component of the breathing assistance device is completed, the breathing assistance device enters the heating pipeline mode.

[0085] In one embodiment, controlling the operating mode of the respiratory assistance device based on the electrical connection status, or providing an entry for controlling the operating mode of the respiratory assistance device corresponding to the electrical connection status, includes:

[0086] When the electrical connection is partially connected or not connected at all, based on the current operating mode of the respiratory assistance device or the operating mode before the last shutdown, the respiratory assistance device is controlled to operate in the heated pipeline mode or the non-heated pipeline mode, or an entrance is provided for controlling the respiratory assistance device to operate in the non-heated pipeline mode.

[0087] Wherein, based on the current operating mode of the respiratory assistance device or the operating mode before the last shutdown, controlling the respiratory assistance device to operate in the heating pipeline mode or the non-heating pipeline mode includes:

[0088] If the breathing assistance device is currently operating in a heated circuit mode or was last shut down, control the breathing assistance device to operate in a heated circuit mode; and / or,

[0089] If the breathing assistance device is currently operating in the non-heated circuit mode or was last shut down, control the breathing assistance device to operate in the non-heated circuit mode.

[0090] That is, in this embodiment, the breathing assistance device maintains the current operating mode or the operating mode before the last shutdown unchanged.

[0091] In actual application, if the breathing assistance device is currently operating in the heating pipe mode or was last shut down before it was shut down, and the controller detects that all or part of the above-mentioned cables are not electrically connected, then it can be considered that all or part of the above-mentioned cables have been accidentally unplugged or an electrical failure has occurred. However, the user still wants the breathing assistance device to operate in the heating pipe mode. At this time, the breathing assistance device is controlled to still operate in the heating pipe mode, and the operating mode is not switched.

[0092] Further, if the breathing assistance device currently or last time before shutdown runs in the heated tube mode, the controller is further configured to control the breathing assistance device to output alarm information for indicating the abnormal connection of the cables.

[0093] Here, although the breathing assistance device still runs in the heated tube mode, since all or part of the plurality of cables are not electrically connected, as known from the foregoing, the heating wire in the heated tube cannot be heated at this time, therefore, in the embodiment, the controller needs to control the breathing assistance device to output alarm information for indicating the abnormal connection of the cables, so that the user can detect the connection of the cables or troubleshoot the electrical fault based on the alarm information, and make the heated tube mode run normally as soon as possible.

[0094] In actual application, when the breathing assistance device is provided with a display screen, the alarm information can be output through the display screen of the breathing assistance device, for example, a pop-up box with alarm information or a flashing prompt icon for prompting the alarm information is output and displayed on the display screen, or the alarm information can also be output through audio of the breathing assistance device.

[0095] If the breathing assistance device currently or last time before shutdown runs in the non-heated tube mode, and the controller detects that all or part of the plurality of cables are not electrically connected, since the plurality of cables do not need to be electrically connected in the non-heated tube mode, the breathing assistance device is still controlled to run in the non-heated tube mode without switching the running mode.

[0096] Further, if the breathing assistance device currently runs in the non-heated tube mode, and the electrical connection is partially not electrically connected, no alarm information related to the abnormal connection of the cables is output.

[0097] In an embodiment, based on the running mode of the breathing assistance device currently or last time before shutdown, an entrance for controlling the breathing assistance device to run in the non-heated tube mode is provided, comprising:

[0098] If the breathing assistance device currently or last time before shutdown runs in the heated tube mode, an entrance for controlling the breathing assistance device to run in the non-heated tube mode is provided.

[0099] In actual applications, if the breathing assistance device is currently running in the heated tube mode or was running in the heated tube mode before the last shutdown, and the controller detects that all or part of the plurality of cables are not electrically connected, it can also be considered that the user intends to run the breathing assistance device in the non-heated tube mode, and therefore all or part of the plurality of cables are pulled out by the user. At this time, the control breathing assistance device provides an entry for controlling the breathing assistance device to run in the non-heated tube mode to trigger the user to further operate to confirm whether to switch the running mode of the breathing assistance device. When the user operation on the entry is detected, further measures are taken to enter the non-heated tube mode or maintain the heated tube mode.

[0100] Figure 3 An example of displaying an entry for controlling the breathing assistance device to run in the non-heated tube mode on the display screen of the breathing assistance device is given. Here, the entry example is specifically a touch screen control with "Enter Non-Heated Tube Mode" displayed, and the user can input the user operation on the entry by clicking the touch screen control. In actual applications, after the user inputs the user operation on the entry by clicking the touch screen control, the controller can also control the display screen of the breathing assistance device to output, for example, Figure 4 The example shows an operation prompt box to further confirm the user's operation intention and avoid unnecessary running mode switching.

[0101] In an embodiment, after providing the entry for controlling the breathing assistance device to run in the non-heated tube mode, if the electrical connection condition is part of the electrical connection, the control breathing assistance device outputs alarm information for prompting the cable to be pulled out in response to the user operation on the entry; if the electrical connection condition is all of the electrical connection, the control breathing assistance device runs in the non-heated tube mode in response to the user operation on the entry. If no user operation is detected, the controller is also used to control the breathing assistance device to continue running in the heated tube mode.

[0102] Referring to Figure 5 For example, if the user operation on the entry is detected, the controller controls the breathing assistance device to output the prompt information "If you want to use the non-heated tube mode, please pull out the cable on the side of the humidifier" in response to the user operation, so as to ensure that all the cables are disconnected in the case of the breathing assistance device running in the non-heated tube mode, and to avoid additional power consumption or safety hazards caused by unnecessary cable connection.

[0103] In addition, if the user operation on the entry is detected, the controller is used to control the breathing assistance device to run in the non-heated tube mode in response to the user operation, and if no user operation is detected, it indicates that the user's operation intention is to run the breathing assistance device in the heated tube mode, at which time the controller is also used to control the breathing assistance device to continue running in the heated tube mode.

[0104] In another embodiment, in the case that all the cables are electrically connected, the controller can also provide an entry for controlling the breathing assistance device to operate in the heated tube mode before controlling the breathing assistance device to operate in the heated tube mode, to control the breathing assistance device to operate in the heated tube mode after detecting a user operation on the entry.

[0105] In an embodiment, based on the electrical connection condition, controlling the operation mode of the breathing assistance device, or providing an entry corresponding to the electrical connection condition for controlling the operation mode of the breathing assistance device, comprises:

[0106] When the electrical connection condition is partial electrical connection or all non-electrically connected, based on the electrical connection change condition of the plurality of cables, controlling the breathing assistance device to operate in the non-heated tube mode or the heated tube mode, or providing an entry corresponding to the electrical connection condition for controlling the breathing assistance device to operate in the non-heated tube mode.

[0107] In an embodiment, based on the electrical connection change condition of the plurality of cables, controlling the breathing assistance device to operate in the non-heated tube mode or the heated tube mode comprises:

[0108] When one of the plurality of cables is changed from electrically connected to non-electrically connected, and the remaining cables of the plurality of cables are all non-electrically connected, controlling the breathing assistance device to operate in the non-heated tube mode.

[0109] In actual application, when the user wants the breathing assistance device to operate in the non-heated tube mode, the user will pull out the plurality of cables one by one, that is, the plurality of cables will be changed from electrically connected to non-electrically connected one by one. Therefore, here, when the controller detects that one of the plurality of cables is changed from electrically connected to non-electrically connected, and the remaining cables of the plurality of cables are all non-electrically connected, it indicates that the plurality of cables have been pulled out, and then the controller can automatically control the breathing assistance device to operate in the non-heated tube mode.

[0110] In an embodiment, based on the electrical connection change condition of the plurality of cables, controlling the breathing assistance device to operate in the non-heated tube mode or the heated tube mode comprises:

Therefore, when the controller detects that one of the cables is changed from not being electrically connected to being electrically connected and the rest of the cables are electrically connected, it indicates that all the cables have been connected. Then, the controller can automatically control the breathing assistance device to run in the heating pipeline mode.

[0113] In an embodiment, when the electrical connection of the cables changes, an entrance for controlling the breathing assistance device to run in the non-heating pipeline mode is provided, including:

[0114] When one of the cables is changed from being electrically connected to not being electrically connected, an entrance for controlling the breathing assistance device to run in the non-heating pipeline mode is provided.

[0115] As described above, in actual application, when the user wants the breathing assistance device to run in the non-heating pipeline mode, the user will pull out the cables one by one, that is, the cables will be changed from being electrically connected to not being electrically connected one by one. Therefore, when the controller detects that one of the cables is changed from being electrically connected to not being electrically connected, it indicates that there is a user intention for the breathing assistance device to run in the non-heating pipeline mode. Then, the controller can provide an entrance for controlling the breathing assistance device to run in the non-heating pipeline mode to further confirm the user intention, so as to achieve more accurate operation.

[0117] When the electrical connection is partial electrical connection or all not being electrically connected, based on the running mode of the breathing assistance device before the last shutdown, the controller controls the breathing assistance device to selectively output alarm information for indicating cable connection abnormity.

At this time, the controller controls the breathing assistance device to output alarm information for indicating cable connection abnormity, so as to further confirm the operation intention. When the breathing assistance device is started, if the breathing assistance device was running in the non-heating pipeline mode before the last shutdown, it is considered that the user intends to run the breathing assistance device in the non-heating pipeline mode, and therefore no alarm information related to cable connection abnormity is output.

[0122] When the electrical connection condition is part electrical connection or all non-electrically connected, based on the electrical connection change of the plurality of cables, the controller controls the breathing assistance device to selectively output alarm information for indicating cable connection abnormity.

[0123] When one of the plurality of cables is changed from electrically connected to non-electrically connected, the controller controls the breathing assistance device to output alarm information for indicating cable connection abnormity.

[0124] When one of the plurality of cables is changed from non-electrically connected to electrically connected, and the remaining cables are all electrically connected, the controller controls the breathing assistance device to stop outputting alarm information for indicating cable connection abnormity.

[0125] Here, if one of the plurality of cables is changed from electrically connected to non-electrically connected, it can be considered that the cable is accidentally unplugged at this time, and at this time, the controller controls the breathing assistance device to output alarm information for indicating cable connection abnormity, so as to ensure that the breathing assistance device can run smoothly. In addition, when one of the plurality of cables is changed from non-electrically connected to electrically connected, and the remaining cables are all electrically connected, it indicates that all the plurality of cables are electrically connected, at this time, the controller controls the breathing assistance device to run in the heating pipeline mode, and stops outputting alarm information for indicating cable connection abnormity.
