Description

A breathing machine

[0001] The present application claims priority to the Chinese patent application No. 202410716589.9 filed on June 04, 2024, and entitled "A breathing machine", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application belongs to the technical field of medical equipment, and specifically relates to a breathing machine. BACKGROUND

[0003] A breathing machine is a medical device used to assist patients with breathing difficulties or unable to breathe independently to complete the breathing process. Breathing machines often need to be transported in or out of the hospital, so the overall size of the breathing machine is gradually becoming smaller.

[0004] Therefore, the internal space layout of the small-sized breathing machine is very compact. In order to facilitate installation and layout, high-heat components such as power supply and circuit board are often arranged in a specific area inside the breathing machine, and the small-sized breathing machine often does not have a good heat dissipation design. Therefore, during use, the heat generated by each heat-generating component is concentrated, which easily leads to abnormal local temperature inside the breathing machine and affects the use, and even causes product damage.

[0005] Some breathing machines have a heat dissipation air duct designed inside, but due to the limitation of the overall size, the electrical components and the heat dissipation air duct are stacked and mixed, and the heat dissipation effect is poor. The heat dissipation air duct of some products is designed to be large and scattered, which has good heat dissipation effect, but it also leads to an increase in the size of the product, making it inconvenient to transport and use. SUMMARY

[0028] The breathing machine further comprises a display assembly, and the display assembly is fixed to the shell.

[0029] Due to the adoption of the above technical scheme, the beneficial effects achieved by the present application are:

[0030] 1、In the present application, the shell has an installation cavity inside for installing the movement unit, and the power supply assembly and each electrical unit are arranged close to different sides of the installation cavity, which not only makes the power supply assembly and each electrical unit dispersedly arranged, reduces the problem of excessive local temperature in the breathing machine caused by concentrated heat, but also makes each heat generating component arranged around the installation cavity, optimizes the structural layout inside the shell, makes the arrangement of each electrical unit and the power supply assembly occupy less space, saves the space inside the shell, and helps the miniaturization design of the breathing machine as a whole.

[0031] In addition, by designing the cooling air duct inside the breathing machine, the air duct can pass through the power supply assembly and each electrical unit in turn and surround the outside of the installation cavity, which not only ensures the heat dissipation effect of the heat generating components, but also makes the air duct path design more simple and convenient, optimizes the air duct path, and simplifies the air duct structure. The air flow flows in the air duct and surrounds the installation cavity, which does not affect the air path assembly in the installation cavity, and avoids the disturbance of the cooling air flow to the air flow in the air path assembly.

[0032] 2. As one embodiment of this application, a support frame and partition assembly for supporting the mechanism unit are provided inside the mounting cavity. The partition assembly includes a first partition located at the top of the support frame and a second partition located on the side of the support frame. A second cooling channel is formed inside the support frame. A first cooling channel is formed on the side of the first partition facing away from the second cooling channel, and a third cooling channel is formed on the side of the second partition facing away from the second cooling channel. The support frame and partition assembly cooperate to form various cooling channels. The power supply component and electrical unit are respectively arranged in each cooling channel, making the internal structure of the mounting cavity more compact, optimizing the structural layout within the mounting cavity, and making reasonable use of the space within the mounting cavity, which helps to reduce the overall size of the machine. Furthermore, each cooling channel is located on the outside of the partition, allowing the partitions to cooperate to form a space for installing the pneumatic components, thus separating the pneumatic components and electrical components, allowing them to be installed and disassembled independently, reducing the risk of interference.

[0033] 3. As one embodiment of this application, a support frame and partition assembly for supporting the movement unit are provided inside the mounting cavity. The partition assembly includes a second partition located on the side of the support frame. A second cooling channel is formed inside the support frame, and a third cooling channel is formed on the side of the second partition opposite to the first cooling channel. A first air vent is opened in the area of ​​the second partition corresponding to the second cooling channel. The first air vent on the second partition connects the second cooling channel and the third cooling channel, allowing the second and third cooling channels to share a single fan, thereby helping to reduce the number of fans and save costs. Simultaneously, it helps to form a circulating airflow for heat dissipation around the mounting cavity. The airflow flows through the second and third cooling channels and is discharged, improving airflow circulation efficiency and heat dissipation effect.

[0034] 4. As one embodiment of this application, the mechanism unit further includes an air path assembly. A support frame for supporting the mechanism unit is provided within the mounting cavity. The support frame forms a first chamber and a second chamber. The power supply assembly is located in the first chamber, and at least a portion of the air path assembly is located in the second chamber. The air path assembly and the power supply assembly are separately disposed within the housing, making their positions relatively independent. Airflow flows entirely within the air path assembly and does not flow to the power supply assembly. Furthermore, the arrangement of the power supply assembly and the electrical unit does not affect the air ducts within the air path assembly, ensuring that the operation of the two components does not interfere with each other. In addition, during maintenance or repair, the power supply assembly or the air path assembly can be removed separately from their respective chambers for individual maintenance. For example, when removing the power supply assembly, it is not necessary to remove the air path assembly, thus avoiding any impact on the air ducts of the air path assembly. This ensures the sealing and connection reliability of each air duct within the air path assembly and avoids a decrease in air duct sealing due to frequent disassembly and reassembly. Meanwhile, when the power supply components and various electrical units are cooled by air, the airflow used for heat dissipation will not enter the air duct inside the air circuit components, thus interfering with the internal airflow and ensuring reliable airflow inside the air circuit components.

[0035] 5、As an embodiment of the present application, the power supply assembly comprises a power supply body and a capacitor body, the capacitor body is located between the power supply body and the air path assembly. The capacitor body has low heat, and is located between the power supply body and the air path assembly, which can separate the heat of the power supply body to some extent, reduce the heat transferred from the power supply body to the air path assembly, and avoid the influence of high temperature of the power supply body on the components of the air path assembly. At the same time, the capacitor body can also block the air flow at the power supply body, so that more air flow for heat dissipation of the power supply body flows on the power supply body side, reducing the air flow flowing from the power supply body side to the air path assembly side, thereby further reducing the influence of the heat dissipation air flow on the internal air duct of the air path assembly, ensuring the internal air path of the breathing machine and the heat dissipation process to be independent of each other.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0057] As shown in FIG. 3, FIG. 4 and FIG. 9, the present application provides a breathing machine, which comprises a shell 1 and a core unit 11, the shell 1 is internally formed with a mounting cavity 12 for mounting the core unit 11, and the core unit 11 comprises an electrical module, the electrical module comprises a power supply assembly 4 and at least one electrical unit 5, and the power supply assembly 4 and each electrical unit 5 are arranged close to different sides of the mounting cavity 12, respectively.

[0058] In an embodiment of the present application, the shell 1 is internally formed with a mounting cavity 12 for mounting the core unit 11, and the power supply assembly 4 and each electrical unit 5 are arranged close to different sides of the mounting cavity 12, respectively, which not only disperses the arrangement of the power supply assembly 4 and each electrical unit 5, reduces the problem of excessive local temperature in the breathing machine caused by concentrated heat, but also arranges each heat generating component around the mounting cavity 12, optimizes the structural layout inside the shell 1, makes the arrangement of each electrical unit 5 and the power supply assembly 4 occupy less space, saves the space inside the shell 1, and helps the overall miniaturization design of the breathing machine.

[0059] In addition, by designing the cooling air duct inside the ventilator, the air duct can pass through the power assembly 4 and each electric unit 5 in turn and surround the outside of the installation cavity 12, which can not only ensure the heat dissipation effect of the heat generating components, but also make the air duct path design more simple and convenient, optimize the air duct path, and simplify the air duct structure. The air flow flows in the air duct and surrounds the installation cavity 12, which does not affect the gas path assembly 6 in the installation cavity 12, and thus the gas path assembly 6 or non-heat generating components can be arranged inside the installation cavity 12, so that the heat generating components and non-heat generating components are arranged separately, thereby the air duct can be designed to individually cool each heat generating component, avoiding the disturbance of the cooling air flow to the airflow in the gas path assembly 6, and at the same time, the influence of the cooling air flow on the temperature of the airflow in the gas path can be avoided.

[0060] It should be noted that in one embodiment, the electric unit 5 includes a circuit board, and in the ventilator product, at least one circuit board is often required for the control of various functions or operations, and in actual use, each circuit board has a large amount of heat, which is a typical heat generating component inside the ventilator.

[0061] As shown in FIG. 8, the electric unit 5 includes a first circuit board 51 and a second circuit board 52, and the first circuit board 51, the second circuit board 52 and the power assembly 4 are arranged close to different sides of the installation cavity 12.

[0062] In one example, in the perspective shown in FIG. 8, the power assembly 4 is located on the left side of the installation cavity 12, the first circuit board 51 is located on the upper side of the installation cavity 12, and the second circuit board 52 is located on the front side of the installation cavity 12. Of course, the positions of the power assembly 4 and the electric units 5 can be adjusted as needed, as long as each heat generating component is on a different side of the installation cavity 12, which is not limited herein.

[0063] Further, as shown in FIGS. 4, 8 and 9, the installation cavity 12 includes a first cooling passage 121, a second cooling passage 122 and a third cooling passage 123, the first circuit board 51 is arranged in the first cooling passage 121, the power assembly 4 is arranged in the second cooling passage 122, and the second circuit board 52 is arranged in the third cooling passage 123.

[0064] It should be noted that the first cooling passage 121, the second cooling passage 122 and the third cooling passage 123 can be connected to each other, so that the air flow in the three cooling passages can freely shuttle, and form a circulating air flow that connects the three cooling passages. At this time, the three cooling passages can share one fan, or each cooling passage can be provided with a fan.

[0065] Of course, the first cooling channel 121, the second cooling channel 122 and the third cooling channel 123 can also be not communicated with each other, so as to form circulating air flow in each cooling channel respectively, and each cooling channel is independently circulated to dissipate heat, improve heat dissipation efficiency, and avoid temperature rising of air flow after cooling a component, so that subsequent cooling efficiency is reduced. At this time, fans can be arranged in the three cooling channels respectively.

[0066] For example, the first cooling channel 121, the second cooling channel 122 and the third cooling channel 123 can also be communicated with any two of them and separated from the other one, so as to form two air flow channels capable of being independently circulated, which are not limited here.

[0067] Further, as shown in FIGS. 4, 8, 9 and 10, the mounting cavity 12 is provided with a support frame 14 for supporting the movement unit 11 and a partition assembly, the partition assembly includes a first partition 15 located at the top of the support frame 14 and a second partition 16 located at the side of the support frame 14, the inside of the support frame 14 forms the second cooling channel 122, the side of the first partition 15 away from the second cooling channel 122 forms the first cooling channel 121, and the side of the second partition 16 away from the second cooling channel 122 forms the third cooling channel 123.

[0068] The support frame 14 and the partition assembly cooperate to form each cooling channel, and the power supply assembly 4 and the electrical unit 5 are arranged in each cooling channel respectively, so that the structure in the mounting cavity 12 is more compact, the structural layout in the mounting cavity 12 is optimized, the space in the mounting cavity 12 is reasonably utilized, and the whole machine size is reduced. Moreover, each cooling channel is located at the outside of the partition, so that the partitions cooperate with each other to enclose a space for mounting the air path assembly 6, the air path assembly 6 and the electrical assembly are relatively separated, can be independently assembled and disassembled, and the risk of interference is reduced.

[0069] Further, as shown in FIGS. 5 and 6, the first circuit board 51 is provided with a first interface 511 for data transmission, a second interface 512 for connecting with other devices in the hospital, for transmitting setting values, monitoring values, alarms and waveform information, a third interface 513 for screen projection during training demonstration or remote monitoring, a fourth interface 514 for exporting trend data, log data, screenshot data and waveform data, a fifth interface 515 for software upgrading, and a sixth interface 516 for connecting with a nurse call.

[0070] As shown in FIG. 7, the rear side of the shell 1 is provided with a plurality of through holes matched with a plurality of communication interfaces provided on the first circuit board 51, and a waterproof cover 19 is arranged outside. A holding handle 18 is arranged on the shell 1, which is used for short-time in-hospital transfer of the ventilator and other purposes. A speaker hole 110 is used for better propagation of audible alarms emitted by a speaker 141.

[0071] In one embodiment, as shown in FIG. 4, FIG. 5, FIG. 8, FIG. 9, FIG. 10, FIG. 11, the movement unit 11 comprises a cooling fan, which comprises a first fan 124 communicating with the first cooling channel 121, and the first fan 124 is arranged towards the first circuit board 51.

[0072] The blowing port of the first fan 124 is arranged towards the first circuit board 51, so that the air flow blown by the first fan 124 can flow towards the first circuit board 51 in a direction perpendicular to the first circuit board 51 and collide with the first circuit board 51. After being blocked by the first circuit board 51, the air flow spreads on the top surface of the first circuit board 51, thereby improving the contact effect of the air flow with the first circuit board 51, prolonging the contact time of the air flow with the first circuit board 51, and improving the cooling effect of the first circuit board 51.

[0073] In other embodiments, the first fan 124 can also blow air laterally from one side of the first circuit board 51 or obliquely towards the first circuit board 51, so that the air flow blown by the first fan 124 flows through the surface of the first circuit board 51, thereby taking away the heat of the first circuit board 51 and achieving cooling. Moreover, the air flow does not collide with the first circuit board 51 violently, which can reduce the air resistance and the noise generated by the air flow.

[0074] Further, as shown in FIG. 4 and FIG. 8, the mounting cavity 12 comprises a support frame 14 for supporting the movement unit 11, a mounting plate 17 for mounting the first fan 124, and a first partition plate 15 for mounting the first circuit board 51. The first partition plate 15 and the mounting plate 17 form the first cooling channel 121 therebetween.

[0075] The first cooling channel 121 is formed by the cooperation of the mounting plate 17 and the first partition plate 15, so that the air flow of the first fan 124 is limited in the space between them, avoiding the air flow from escaping to the inside of the mounting cavity 12, and reducing the influence of the cooling air flow on the components and air paths inside the mounting cavity 12.

[0076] As shown in FIG. 8, the mounting plate 17 is recessed towards the upper side to increase the height of the first cooling channel 121, thereby reducing the resistance of the cooling air flow when flowing, and being able to increase the mounting space of the components, avoiding interference, and being able to reduce the heat transfer from the first circuit board 51 to the first fan 124.

[0077] Further, as shown in FIG. 8, a heat-conducting member 8 is arranged between the first circuit board 51 and the first fan 124.

[0078] The heat-conducting member 8 can be made of a material with high heat-conducting performance and is in contact with the first circuit board 51, so as to improve the heat exchange efficiency and accelerate the heat dissipation of the first circuit board 51. Further, the heat transfer path of the first circuit board 51 is that the heat is transferred from the first circuit board 51 to the heat-conducting member 8, and then the air flow blown by the first fan 124 is used to air-cool the heat-conducting member 8 to reduce the temperature of the heat-conducting member 8. Thus, the heat exchange efficiency between the first circuit board 51 and the air is improved, and the heat dissipation of the first circuit board 51 is accelerated.

[0079] As shown in FIG. 8, the heat-conducting member 8 includes a first heat-conducting part 81 in contact with the first circuit board 51, and a second heat-conducting part 82 in contact with the first heat-conducting part 81, and the area of the second heat-conducting part 82 is greater than that of the first heat-conducting part 81.

[0080] The installation position of the first heat-conducting part 81 is the position of the core processor on the first circuit board 51, i.e., the position of the component with the largest heat generation on the first circuit board 51. The first heat-conducting part 81 is in contact with the first circuit board 51 to transfer the heat to the second heat-conducting part 82 through the high heat-conducting performance of the first heat-conducting part 81, so as to prevent local overheating from causing damage to the components. The second heat-conducting part 82 is made of a material with high heat-conducting coefficient, is arranged above the first heat-conducting part 81 and is in contact with the first heat-conducting part 81, and is used to increase the heat dissipation area while conducting heat.

[0081] As shown in FIGS. 4, 8 and 9, due to the existence of the mounting plate 17, the first cooling channel 121 forms a relatively closed environment, and only the front side has a gas passage, so that the air is forced to diffuse around in the horizontal direction after being blown to the second heat-conducting part 82, and is used to dissipate heat for other components on the first circuit board 51, and is finally discharged from the front side.

[0082] As shown in FIGS. 10 and 11, the mounting cavity 12 is provided with a support frame 14 for supporting the movement unit 11 and a partition plate assembly. The partition plate assembly includes a second partition plate 16 located at the side of the support frame 14. The inside of the support frame 14 forms a second cooling channel 122. The side of the second partition plate 16 away from the first cooling channel 121 forms a third cooling channel 123. The second partition plate 16 has a first air passage 163 formed in the region corresponding to the second cooling channel 122.

[0083] The first air passage 163 on the second partition plate 16 connects the second cooling channel 122 and the third cooling channel 123, so that the second cooling channel 122 and the third cooling channel 123 can share one fan, thereby helping to reduce the number of fans and save costs. At the same time, it is helpful to form a circulating air flow for heat dissipation around the mounting cavity 12. The air flow flows through the second cooling channel 122 and the third cooling channel 123 and is discharged, thereby improving the air flow circulation efficiency and improving the heat dissipation effect.

[0085] In an embodiment, as shown in FIG. 14, the first cooling channel 121 can be in communication with the second cooling channel 122, so that the air flow in the first cooling channel 121 flows into the second cooling channel 122 at the front side of the housing 1 after completing the cooling of the first circuit board 51, and merges with the air flow in the second cooling channel 122 and the third cooling channel 123 to flow to the rear side of the housing 1, and then is discharged from the housing 1. The air flow in the housing 1 flows smoothly and unobstructed. Two air outlets can also be arranged in the housing 1, one of which is in communication with the first cooling channel 121, and the other is in communication with the second cooling channel 122 and / or the third cooling channel 123, so that the air flow in the first cooling channel 121 is discharged from one air outlet, and the air flow in the second cooling channel 122 and the third cooling channel 123 is discharged from the other air outlet.

[0086] In an embodiment, as shown in FIG. 10, the core unit 11 includes a cooling fan, and the cooling fan includes a second fan 125 in communication with the second cooling channel 122.

[0087] As shown in FIG. 10 and FIG. 11, the second fan 125 is arranged at the rear side of the mounting cavity 12, and the air flow blown by the second fan 125 flows from the rear side to the front side of the mounting cavity 12, flows through the second cooling channel 122 to the third cooling channel 123 at the front side, and then turns at the cover plate 3 at the front side of the mounting cavity 12, and then flows backward at the right side of the mounting cavity 12 to the rear side of the mounting cavity 12 and is discharged from the rear side.

[0088] As shown in FIG. 10, the power supply assembly 4 includes a housing 43 and a power supply body 41 arranged in the housing 43, and the housing 43 is provided with a second air passage 431 penetrating through the inside and outside of the housing 43, so that the cooling air can pass through the second air passage 431 to enter the inside of the housing 43 to cool the power supply body 41.

[0089] As shown in FIG. 8 and FIG. 10, the support frame 14 is in U shape and opens upward, the first partition plate 15 is installed at the U-shaped opening position of the support frame 14, which plays a role of reinforcement and also bears the installation of the first circuit board 51, the mounting plate 17 and other accessories.

The support frame 14 is installed with the loudspeaker 141 for audible alarm, and the second partition plate 16 is installed at the front side of the support frame 14, which is installed with the second circuit board 52 for product power function control and the air vent 161 for communicating with the airflow outlet of the air path assembly 6 to provide therapeutic gas to the patient.

[0090] In an embodiment of the present application, as shown in FIG. 10, the core unit 11 further comprises the air path assembly 6, and the installation cavity 12 is provided with a support frame 14 for supporting the core unit 11. The support frame 14 is internally formed with a first chamber 1107 and a second chamber 1108. The power supply assembly 4 is located in the first chamber 1107, and at least part of the air path assembly 6 is located in the second chamber 1108.

[0091] The air path assembly 6 and the power supply assembly 4 are separately arranged inside the shell 1, so that their positions are relatively independent. The airflow flows completely inside the air path assembly 6 and does not flow to the power supply assembly 4, and the arrangement of the power supply assembly 4 and the electrical unit 5 does not affect the air ducts in the air path assembly 6, so that the work of the two assemblies does not affect each other. In addition, during maintenance or maintenance, the power supply assembly 4 or the air path assembly 6 can be taken out from the respective cavities for separate maintenance. For example, when the power supply assembly 4 is removed, the air path assembly 6 does not need to be removed, so as not to affect the air ducts of the air path assembly 6, thereby ensuring the sealing and connection reliability of the air ducts in the air path assembly 6, and avoiding the sealing of the air ducts due to frequent assembly and disassembly. At the same time, when the power supply assembly 4 and the electrical unit 5 are air-cooled and heat-dissipated, the airflow for heat dissipation does not enter the air ducts inside the air path assembly 6, so as not to interfere with the flow of the internal airflow, thereby ensuring the reliable flow of the internal airflow of the air path assembly 6.

[0092] It should be noted that the main part of the air path assembly 6 is arranged in the second chamber 1108, but part of the area or part of the pipeline extends outside the second chamber 1108 because the air path assembly 6 needs to be connected with many pipelines.

At the same time, the capacitor body 42 can also play a blocking role for the air flow at the power supply body 41, and the air flow for heat dissipation of the power supply body 41 flows more on the side of the power supply body 41, reducing the air flow flowing from the side of the power supply body 41 to the side of the air path assembly 6, thereby further reducing the influence of the heat dissipation air flow on the internal air duct of the air path assembly 6, ensuring the internal air path of the breathing machine works, and the heat dissipation process does not interfere with each other.
