Detailed Description
The invention provides a respiratory therapy device and a circulating heating pipeline, and in order to make the purpose, the technical scheme and the effect of the invention clearer and clearer, the invention is further described in detail by referring to the attached drawings and taking examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the respiratory therapy equipment in the prior art, for the parts which cannot be disassembled or are inconvenient to disassemble, the existing disinfection method is difficult to be applied to disinfection, so that the problem of cross infection is easily caused because the gas loop is difficult to be thoroughly disinfected. If the high-temperature gas can flow in the gas loop or the high-temperature gas can be filled in the gas loop in a mode of directly utilizing cold heat exchange, and the high-temperature gas at least flows through or fills the position to be disinfected, at least one part of gas branch can be disinfected, no matter whether the parts through which the high-temperature gas flows are convenient to disassemble, the disinfection effect is not influenced, even according to the disinfection mode in the prior art, the parts which need to be disassembled originally do not need to be disassembled, and the disinfection of the ventilation part can be completed.
Based on the above idea, the present invention provides a respiratory treatment apparatus, comprising: the gas flow channel and the heating device are used for generating a preset temperature higher than or equal to the preset temperature. It is understood that the present invention does not need to be specifically limited to the preset value, and those skilled in the art can adaptively select the preset value according to the use environment of the respiratory therapy apparatus, the virus which may be infected, and the like; the specific structure of the heating device is adapted to the temperature value which can be generated by the heating device, and a person skilled in the art can also determine which heating device to use (such as a resistance wire, a power-on heating net, a heating plate, a heating pipe and the like, which are not exhaustive) according to the temperature required by sterilization and disinfection, so that creative labor is not required, and the implementation of the technical scheme of the invention is not influenced; therefore, whatever the heating device is used, the temperature geometry generated by the heating device during disinfection is controlled, and the heating device and the disinfection device are all within the protection scope of the invention.
In addition, the heat generating device should be disposed at a position capable of conducting the generated heat to the gas in the gas flow channel, and in practical implementation, the positions meeting the requirements are many, such as: the heating device is directly arranged in the gas flow channel, and when the heating device generates high temperature and emits heat outwards, the heat can be directly conducted to the gas, so that the temperature of the gas is increased to form high-temperature gas; for another example: the heating device is arranged on the outer wall of the pipeline (the pipeline is a pipeline forming a gas flow channel), and when the heating device generates high temperature and emits heat outwards, the heat is conducted to the gas through the wall of the pipeline, so that the temperature of the gas is increased to form high-temperature gas; for another example: the heating device is arranged in the cavity outside the pipeline, when the heating device generates high temperature and emits heat outwards, heat is conducted to the pipeline, and then the heat is conducted to the gas through the pipeline wall, so that the temperature of the gas is increased to form high-temperature gas; for another example, the external pipeline is provided with a heating device in the external pipeline, when the heating device generates high temperature and emits heat outwards, the heat is firstly conducted to the pipeline wall of the external pipeline and the gas in the external pipeline, and then the temperature of the gas is increased by connecting the external pipeline and the gas flow channel to form high-temperature gas. It is understood that, besides the above solutions, there are many locations where the heat generating device can be implemented to satisfy the requirement that at least a part of the gas flow channel is filled with high-temperature gas, and the present invention cannot be listed for this purpose, and the locations where the heat generating device is installed to satisfy the requirement all belong to the protection scope of the present invention.
As a first preferred embodiment of the present invention, the gas flow path includes: a first intake branch, the first intake branch comprising: at least one first gas intake pipe, the device that generates heat sets up in the first gas intake pipe, the outer wall of first gas intake pipe or the outside of first gas intake pipe (when the device that generates heat is the illumination formula device that generates heat, can shine the light that launches to first gas intake pipe, make first gas intake pipe heat up, the gaseous temperature in the indirect rising pipeline).
As a respiratory therapy device, there is at least one air inlet: for a respiratory therapy apparatus that generates gas itself and supplies the gas to a patient, there is one inlet (two inlets may be present if there are multiple gases) for introducing the generated gas into the gas flow path; for a respiratory therapy apparatus in which one gas is introduced from the outside and only one gas is introduced from the outside, there is also a gas inlet for introducing the introduced gas into the gas flow path; for a respiratory therapy device introducing multiple gases from the outside, a plurality of gas inlets may exist, or even one gas inlet may exist, and when two or more gases share the same gas inlet, the phenomenon that the number of gas inlets is less than that of the gases can occur; the situation is different according to different types of respiratory therapy equipment, but in any case, the respiratory therapy equipment has at least one air inlet.
When only one air inlet exists in the gas flow channel, the heating device is preferably arranged at the first air inlet branch, so that heat emitted by the heating device can be directly conducted to gas which just enters the gas flow channel, high-temperature gas can be spread or flow through the whole gas flow channel to sterilize the whole gas flow channel, the sterilization effect is improved, and bacteria and viruses in the gas flow channel are killed as far as possible. Even if the heating device is not arranged at the air inlet of the first air inlet branch, the disinfection at the position needing disinfection can be carried out by adding a circulating pipeline, controlling the rotation direction of a gas flow driving source (air suction and blowing), or carrying out cold-heat exchange and the like. When the gas channel has only one gas inlet, the first gas inlet branch is also a part of the main channel, or is integrally formed with the main channel without branches, and the heat generating device is disposed at any position of the first gas inlet branch, i.e., the heat generating device can be disposed at any position of the main channel. In the internal airflow channel structure of the respiratory therapy apparatus 100 shown in fig. 3, during sterilization, the second air inlet 112 does not need to be sterilized, and a one-way valve is disposed on the corresponding second air inlet branch, so that it can be regarded as only having the first air inlet branch, and a fan 115 is disposed between the first air inlet pipe 114 and the main flow pipe 116, in this embodiment, the heat generating device is preferably disposed at the first air inlet branch 114, and specifically may be disposed inside the first air inlet pipe 114, on an outer wall of the first air inlet pipe 114, and/or on an outer side of the first air inlet pipe 114.
When more than one air inlet is arranged in the air flow passage, the number and the position of the heating devices are preferably arranged according to the air inlet branch to be disinfected, as shown in fig. 1, the respiratory therapy apparatus 100 has two air inlets, a first air inlet 111 for introducing air, a second air inlet 112 for introducing high pressure oxygen, wherein, the inlet branch that hyperbaric oxygen corresponds does not need to disinfect, therefore, in order to reduce cost, simplify the structure and improve disinfection effect, only be provided with the device that generates heat (quantity is decided according to the disinfection effect of single device that generates heat) in the inlet branch that the air corresponds (114 is the first gas intake pipe of respiratory therapy equipment in figure 3), if one can reach and predetermine disinfection effect, then only set up one can, if two superpose users can reach and predetermine disinfection effect, then set up two devices that generate heat, analogize in proper order).
If two or more than two air inlet branches need to be disinfected, the heating devices are provided with multiple groups, the specific number is adapted to the number of the air inlet branches needing to be disinfected, namely, each air inlet branch needing to be disinfected is provided with one group of heating devices (each group of heating devices comprises one or more heating devices, and whether the number of the groups is the same or not is determined according to the requirement).
Further, the respiratory therapy apparatus further comprises: and an air flow driving source (such as a fan 115, an air pump and the like in fig. 3) for driving the air in the air flow channel to flow, wherein the flowing high-temperature air can flow through the position to be disinfected more quickly than the air in the air flow channel is gradually heated to be high-temperature air by means of heat conduction, so that the disinfection efficiency is improved. The gas flow driving source can be arranged in the respiratory treatment equipment or externally connected with the respiratory treatment equipment, and for the gas flow driving source arranged in the original structure, the invention preferably uses the built-in gas flow driving source, thereby reducing the operation difficulty of disinfection.
Preferably, the respiratory therapy apparatus further comprises: a filter, which is disposed at the outlet of the gas flow passage, please refer to fig. 3, and fig. 3 shows 113 a filter for the respiratory therapy apparatus 100. Because the high-temperature gas adopted by the invention is used for sterilization, when the high-temperature gas is discharged out of the gas flow channel, the high-temperature gas carries great heat, and if biological activities are nearby, the high-temperature gas is very easy to scald; under the condition that the filter is arranged, the filter can greatly reduce the discharge speed of high-temperature gas and reduce the scalding risk; therefore, the present invention preferably employs a filter capable of reducing the discharge speed of the high-temperature gas, such as filter cotton, a tight filter net, or a component having both flow-limiting and filtering functions.
Preferably, the respiratory therapy apparatus further comprises: a circulation conduit for connection between the inlet 111 and the outlet of the gas flow channel (as shown in figure 5). Under the condition that the circulating pipeline is arranged, high-temperature gas for disinfection does not need to be discharged to the outside, and only can circularly flow between the gas flow channel and the circulating pipeline; the gas flow channel is communicated with the circulating pipeline to form a complete disinfection circulating loop, so that scalding can be effectively avoided on the one hand, the temperature of gas in the disinfection circulating loop is guaranteed on the other hand, otherwise, externally-connected low-temperature gas enters all the time, and the disinfection energy consumption is increased.
Furthermore, the circulating pipeline is a double-layer pipeline, a gap is reserved between the two layers of pipelines, and the phenomenon that the pipeline is too high in temperature and scalding accidents are avoided. It can be understood that the gas flow driving source, the filter and the circulating pipeline can be optionally used by matching two or three of them, and there is no conflict among the three.
As a second preferred embodiment of the present invention, the gas flow passage includes a first gas intake branch including a first gas intake pipe; the heating device comprises a vent pipe used as part or all of the first gas inlet pipe and a heating element fixed by the vent pipe.
That is, in this embodiment, the heat generating device is used as a pipeline of the gas flow passage and a fixing structure of the heat generating element, and the heat generating element may be a component or assembly having a heat generating function, such as a heating wire, a heating plate, and the like.
When only one first gas inlet pipe is arranged, the breather pipe is connected with the first gas inlet pipe. When the respiratory therapy equipment is internally provided with a gas flow driving source, the vent pipe can be arranged between the first gas inlet pipe and the gas flow driving source and also can be connected to one end of the first gas inlet pipe, which is deviated from the gas flow driving source. Even if the heating device is not arranged at the air inlet of the first air inlet branch, the disinfection at the position needing disinfection can be carried out by adding a circulating pipeline, controlling the rotation direction of a gas flow driving source (air suction and blowing), or carrying out cold-heat exchange and the like. When there is only one gas inlet in the gas flow channel, the first gas inlet branch is also a part of the main flow channel, or is integrally formed with the main flow channel and the main flow channel is not branched, and the heat generating device is disposed at any position of the first gas inlet branch, i.e. it is considered that the heat generating device can be disposed at any position of the main flow channel, for example, upstream or downstream of the gas flow driving source.
When the first gas inlet pipes are arranged in a plurality, the first gas inlet pipes are sequentially connected in the length direction through the vent pipes of the heating device. If the number of the heat generating devices is two or more, the heat generating devices may be optionally disposed between the plurality of first gas inlet pipes, or at the head end or the tail end of the first gas inlet branch, and the positions of the plurality of heat generating devices are not particularly limited in the present invention. If only one heating device is provided, the heating device may be optionally disposed between any two adjacent first gas inlet pipes, or at the head end or the tail end of the first gas inlet branch, and the position of the heating device is also not specifically limited in the present invention. However, it can be understood that the heating device is disposed at the head end of the first air inlet branch (the air inlet of the first air inlet branch), so that the heat emitted by the heating device can be directly conducted to the gas which just enters the gas flow channel, and the high-temperature gas can spread over or flow through the whole gas flow channel, so as to sterilize the whole gas flow channel, improve the sterilization effect, and kill the bacteria and viruses in the gas flow channel as much as possible.
When gas flow path has more than one air inlet, the branch road that admits air of preferred disinfection as required sets up the quantity and the position of the device that generates heat, respiratory therapy equipment's air inlet is provided with two, one is used for leading-in air, one is used for leading-in hyperbaric oxygen, wherein, the branch road that admits air that hyperbaric oxygen corresponds does not need to disinfect, therefore, in order to reduce cost, simplify the structure and improve disinfection effect, only be provided with the device that generates heat in the branch road department that admits air that the air corresponds (quantity is decided according to the disinfection effect of the device that generates heat singly, if one can reach and predetermine disinfection effect, then only set up one can, if two stack users can reach and predetermine disinfection effect, then set up two devices that generate heat.
If two or more than two air inlet branches need to be disinfected, the heating devices are provided with multiple groups, the specific number is adapted to the number of the air inlet branches needing to be disinfected, namely, each air inlet branch needing to be disinfected is provided with one group of heating devices (each group of heating devices comprises one or more heating devices, and whether the number of the groups is the same or not is determined according to the requirement).
Further, the respiratory therapy apparatus further comprises: the gas flow driving source (such as a fan, a gas pump and the like) is used for driving the gas in the gas flow channel to flow, and compared with the method of gradually heating the gas in the gas flow channel to be high-temperature gas in a heat conduction mode, the flowing high-temperature gas can flow through the position to be disinfected more quickly, and the disinfection efficiency is improved. The gas flow driving source can be arranged in the respiratory treatment equipment or externally connected with the respiratory treatment equipment, and for the gas flow driving source arranged in the original structure, the invention preferably uses the built-in gas flow driving source, thereby reducing the operation difficulty of disinfection.
Preferably, the respiratory therapy apparatus further comprises: a filter disposed at an outlet of the gas flow passage. Because the high-temperature gas adopted by the invention is used for sterilization, when the high-temperature gas is discharged out of the gas flow channel, the high-temperature gas carries great heat, and if biological activities are nearby, the high-temperature gas is very easy to scald; under the condition that the filter is arranged, the filter can greatly reduce the discharge speed of high-temperature gas, reduce the gas temperature and reduce the scalding risk; therefore, the present invention preferably employs a filter capable of reducing the discharge speed of the high-temperature gas, such as filter cotton, a tight filter net, or a component having both flow-limiting and filtering functions.
Preferably, the respiratory therapy apparatus further comprises: a circulation conduit for connection between the inlet 111 and the outlet of the gas flow channel. Under the condition that the circulating pipeline is arranged, high-temperature gas for disinfection does not need to be discharged to the outside, and only can circularly flow between the gas flow channel and the circulating pipeline; the gas flow channel is communicated with the circulating pipeline to form a complete disinfection circulating loop, so that scalding can be effectively avoided on the one hand, the temperature of gas in the disinfection circulating loop is guaranteed on the other hand, otherwise, externally-connected low-temperature gas enters all the time, and the disinfection energy consumption is increased.
Furthermore, the circulating pipeline is a double-layer pipeline, a gap is reserved between the two layers of pipelines, and the phenomenon that the pipeline is too high in temperature and scalding accidents are avoided. It can be understood that the gas flow driving source, the filter and the circulating pipeline can be optionally used by matching two or three of them, and there is no conflict among the three.
As a third preferred embodiment of the present invention, the gas flow path includes: the air conditioner comprises a first air inlet branch, a second air inlet branch and a main runner. It should be noted that, in the present invention, the types of the gases introduced by the first air intake branch and the second air intake branch are not limited, and the first air intake branch and the second air intake branch may respectively and independently introduce different gases, or may respectively and independently introduce the same gas; it is also possible to introduce a plurality of gases simultaneously from any one of the branches and to introduce any one of the gases or another gas from the other branch; or may both introduce multiple gases; the kind of gas introduced does not affect the implementation of the solution of the present invention, and certainly, it is within the scope of the present invention to introduce a certain gas, which results in the need for the branch to be sterilized separately, to change the respiratory therapy equipment or parameters, or to make the branch not need to be sterilized, since the adjustment of the structure or parameters caused by this case is not necessary to create creative efforts for those skilled in the art.
The first intake branch includes: at least one first gas intake manifold, the second intake branch comprising: at least one second gas inlet pipe, the sprue includes: at least one main flow conduit within which gas within the first gas inlet conduit mixes with gas within the second gas inlet conduit. That is, the first gas inlet pipe and the second gas inlet pipe are connected in parallel to the main flow pipeline, and the connection mode may be a three-way joint (such as a Y-shaped joint, an integrally formed halberd-shaped joint, etc.); or directly connected with the main flow pipeline without being connected through a joint, or directly integrated with the main flow pipeline.
The invention is explained by taking the example that the first gas inlet pipe is communicated with air, and the second gas inlet pipe is communicated with high-pressure oxygen. For cost saving, it is preferred to provide the heat generating means in the first gas inlet conduit, and/or the main flow conduit, since the passage for the oxygen under pressure does not require heat sterilization.
Preferably, the heating device is disposed in the main flow pipeline, on the outer wall of the main flow pipeline, or on the outer side of the main flow pipeline (when the heating device is an illumination type heating device, emitted light can be irradiated to the main flow pipeline, so that the temperature of the main flow pipeline is raised, and the temperature of the gas in the pipeline is indirectly raised). Alternatively, the heating means may be arranged inside the first gas inlet conduit, on the wall of the first gas inlet conduit or outside the first gas inlet conduit.
In this embodiment, the present invention does not exclude the presence of more intake branches; it is not excluded that the inlet branch (the first inlet branch, the second inlet branch and/or the other inlet branches) is provided with another heat generating device in addition to the heat generating device arranged in the main flow channel.
When only the main flow passage needs to be sterilized, the heat generating device is preferably disposed at an intersection of the main flow passage and the first air inlet branch passage and/or the second air inlet branch passage, or at an end of the main flow passage near the intersection. In addition to this way, the heating device can be arranged near or at any position of the main flow channel, and the high-temperature gas can flow through the position to be disinfected by controlling the gas flow driving source to rotate forwards (air suction) and reversely (air blowing) and the like; or the gas in the main flow passage is gradually heated and disinfected in a cold-heat exchange mode. Therefore, no matter how the position relation between the heating device and the main flow channel is, as long as the heat can be conducted into the main flow channel, the aim of disinfecting the main flow channel can be fulfilled.
When at least one air inlet branch and the main flow channel need to be disinfected, a heating device can be arranged on the air inlet branch to be disinfected, or heating devices are arranged at the air inlet branch and the main flow channel, or a pipeline is additionally arranged between the free ends of the air inlet branch and the main flow channel, so that high-temperature gas in the main flow channel can flow through the air inlet branch at least once; or the high-temperature gas flows through the position to be disinfected by controlling the gas flow driving source to rotate forwards (air suction) and reversely (air blowing) and the like; or the temperature of the gas in the main flow passage and the gas inlet branch passage to be disinfected is gradually increased in a cold and heat exchange mode. Therefore, regardless of the number and the positions of the heating devices, the disinfection purpose of the main flow passage and the air inlet branch can be realized by adopting the structure of the embodiment.
Further, the respiratory therapy apparatus further comprises: the gas flow driving source (such as a fan, a gas pump and the like) is used for driving the gas in the gas flow channel to flow, and compared with the method of gradually heating the gas in the gas flow channel to be high-temperature gas in a heat conduction mode, the flowing high-temperature gas can flow through the position to be disinfected more quickly, and the disinfection efficiency is improved. The gas flow driving source can be arranged in the respiratory treatment equipment or externally connected with the respiratory treatment equipment, and for the gas flow driving source arranged in the original structure, the invention preferably uses the built-in gas flow driving source, thereby reducing the operation difficulty of disinfection.
Preferably, the respiratory therapy apparatus further comprises: a filter disposed at an outlet of the gas flow passage. Because the high-temperature gas adopted by the invention is used for sterilization, when the high-temperature gas is discharged out of the gas flow channel, the high-temperature gas carries great heat, and if biological activities are nearby, the high-temperature gas is very easy to scald; under the condition that the filter is arranged, the filter can greatly reduce the discharge speed of high-temperature gas, reduce the gas temperature and reduce the scalding risk; therefore, the present invention preferably employs a filter capable of reducing the discharge speed of the high-temperature gas, such as filter cotton, a tight filter net, or a component having both flow-limiting and filtering functions.
Preferably, the respiratory therapy apparatus further comprises: a circulation conduit for connection between the inlet and the outlet of the gas flow channel. Under the condition that the circulating pipeline is arranged, high-temperature gas for disinfection does not need to be discharged to the outside, and only can circularly flow between the gas flow channel and the circulating pipeline; the gas flow channel is communicated with the circulating pipeline to form a complete disinfection circulating loop, so that scalding can be effectively avoided on the one hand, the temperature of gas in the disinfection circulating loop is guaranteed on the other hand, otherwise, externally-connected low-temperature gas enters all the time, and the disinfection energy consumption is increased. Besides, the arrangement of the circulating pipeline in the embodiment can avoid the need of considering the position of the heating device, and the disinfection of the air inlet branch can be performed through the circulating pipeline even if the heating device is arranged at the air outlet of the air flow passage.
Furthermore, the circulating pipeline is a double-layer pipeline, a gap is reserved between the two layers of pipelines, and the phenomenon that the pipeline is too high in temperature and scalding accidents are avoided. It can be understood that the gas flow driving source, the filter and the circulating pipeline can be optionally used by matching two or three of them, and there is no conflict among the three.

It is noted that the first gas inlet pipe and the second gas inlet pipe are connected in parallel to the main flow pipeline, and the connection mode may be through a joint (such as a "Y" joint, an integrally formed "halberd" joint, etc.); or directly connected with the main flow pipeline and not connected through a joint; or directly integrated with the main flow pipe.
In this embodiment, the heat generating device includes: a ventilation pipe used as a main flow pipe or as the joint, and a heating element fixed by means of the ventilation pipe.

In addition, the heat generating device should be disposed at a position capable of transferring the generated heat to the gas in the circulation pipe 200, such as being directly disposed in the circulation pipe 200, such as being attached to an outer wall of the circulation pipe 200 (attached to an outer wall of the inner pipe when the circulation pipe 200 is a double-layer pipe), such as being disposed outside the circulation pipe 200 (disposed between the inner pipe and the outer pipe when the circulation pipe 200 is a double-layer pipe) when the heat generating device can perform non-contact heat transfer.
Further, the circulating pipeline 200 is a double-layer pipeline, and a gap is reserved between the two layers of pipelines, so that the pipeline temperature is prevented from being too high, and scalding accidents are prevented.
