Generally, in some respiratory devices, the airflow drive assembly is also capable of inhaling air so that the air is mixed with oxygen to form a gas for the patient.

The oxygen inlet assembly 201 is used to connect with an oxygen supply device, and oxygen of the oxygen supply device flows into the breathing device through the oxygen inlet assembly 201. The oxygen inlet assembly 201 may include a gas supply connection to an oxygen supply, a proportional valve to regulate the flow rate of oxygen, a flow sensor to detect the flow rate of oxygen, and the like.

According to the breathing apparatus of the present embodiment, when the flow driving assembly is activated, the oxygen flowing in through the oxygen inlet assembly 201 flows out from the main airway assembly 210 under the action of the flow driving assembly, so as to form the gas for breathing of the patient. This embodiment respiratory device is through with the first module 100 that includes the air current drive assembly and the second module 200 that includes oxygen inlet subassembly 201 and main air flue subassembly 210 along the range upon range of setting of vertical direction, the rational utilization space of vertical direction, reduced the size of device horizontal direction, and then reduced the area of device, made things convenient for storing of device.

In one embodiment of the breathing apparatus of this embodiment, the first module 100 further comprises an air filter assembly 102, and an air outlet of the air filter assembly 102 is connected to an air inlet of the airflow driving assembly.

The air filter assembly 102 is used for filtering air, and a specific air filter may be HEPA (HEPA, i.e., a high efficiency air filter, which can trap particulate dust and various suspended matters larger than 0.5 μm).

The first module 100 of the present embodiment may be a unit formed of members having substantially uniform height positions, that is, a one-layer structure formed of members arranged substantially horizontally. Specifically, in this embodiment, the first module 100 is a layered structure formed by arranging at least the air filter assembly 102 and the turbine mechanism 101 in order in the horizontal direction. Similarly, the second module 200 may also be a unit formed by components with substantially the same height position, that is, a layer structure formed by a plurality of components arranged substantially horizontally, and in this embodiment, the second module 200 is a layer structure formed by at least the oxygen inlet assembly 201 and the main air duct assembly 210 arranged in sequence in the horizontal direction. The first module 100 and the second module 200 are stacked, which corresponds to a two-layer structure in the height direction. Specifically, all the components of the first module 100 may be positioned above all the components of the second module 200 to form a two-layer structure; it is also possible that all the components of the first module 100 are located below all the components of the second module 200 to form a two-layer structure.

When the airflow driving assembly is started, the air filtered by the air filtering assembly 102 and the oxygen flowing in through the oxygen inlet assembly 201 are mixed and then flow out from the main airway assembly 210 under the action of the airflow driving assembly, so as to form the gas for breathing of the patient. This embodiment respiratory device is through with the first module 100 that includes air filter component 102 and air current drive assembly and the second module 200 that includes oxygen inlet component 201 and main air flue subassembly 210 along the range upon range of setting of vertical direction, the rational utilization space of vertical direction, reduced the size of device horizontal direction, and then reduced the area of device, made things convenient for storing of device.

In a specific embodiment of the present embodiment, the first module 100 is disposed above the second module 200, i.e. all components of the first module 100 are above all components of the second module 200.

Specifically, referring to fig. 1 and 2, in the present embodiment, the air filter assembly 102 and the turbine mechanism 101 have substantially the same height and are sequentially arranged in the horizontal direction; the oxygen inlet assembly 201 and the main air duct assembly 210 are approximately uniform in height and are arranged in series in the horizontal direction. The air filter assembly 102 and the turbine mechanism 101 are both located above the oxygen inlet assembly 201 and the main air duct assembly 210, the air filter assembly 102 and the turbine mechanism 101 forming an upper layer structure, and the oxygen inlet assembly 201 and the main air duct assembly 210 forming a lower layer structure.

By having the first module 100 disposed above the second module 200, the components of the breathing apparatus are more rationally arranged. Wherein, oxygen inlet subassembly 201 and main air flue subassembly 210 set up in the below, and like this, the below that is close to the device with the interface of the pipeline that oxygen inlet subassembly 201 and main air flue subassembly 210 are connected, and the pipeline of connecting with both does not basically occupy the peripheral vertical direction space of respiratory device, is favorable to dwindling the space that the device occupy, and is difficult for leading to the pipeline in disorder.

Further, the arrangement direction between the air filter assembly 102 and the airflow driving assembly is parallel to the arrangement direction between the oxygen inlet assembly 201 and the main air passage assembly 210. For example, referring to fig. 1 and 2, air filter assembly 102 and the airflow driver assembly are arranged in a left-right direction, and correspondingly, oxygen inlet assembly 201 and main air duct assembly 210 are also arranged in a left-right direction.

It can be understood that, by arranging the arrangement direction between the air filter assembly 102 and the airflow driving assembly in parallel with the arrangement direction between the oxygen inlet assembly 201 and the main air duct assembly 210, the first module 100 and the second module 200 extend in the same direction in the horizontal direction, that is, the upper layer structure and the lower layer structure occupy the space with the same dimension in the horizontal direction, so as to avoid that the first module 100 and the second module 200 are arranged in different directions (the arrangement direction is different, for example, the air filter assembly 102 and the airflow driving assembly are arranged in the front-back direction, and the oxygen inlet assembly 201 and the main air duct assembly 210 are arranged in the left-right direction), which results in too large space occupied by the whole device, and is beneficial to the miniaturization design of the device.

In this embodiment, to further reduce the occupied space of the device, the air filter assembly 102 may be disposed directly above the oxygen inlet assembly 201, and the main air duct assembly 210 is disposed on a side of the oxygen inlet assembly 201 close to the airflow driving assembly.

Wherein the primary air channel assembly 210 is located on a side of the oxygen inlet assembly 201 adjacent to the airflow driving assembly, i.e. the primary air channel assembly 210 and the turbo mechanism 101 are disposed on the same side of the oxygen inlet assembly 201 and the air filter assembly 102. Referring to FIG. 2, the main air path assembly 210 is located to the right of the oxygen inlet assembly 201, and the turbine mechanism 101 is also located to the right of the air filter assembly 102.

Set up air filter component 102 directly over oxygen inlet subassembly 201, both are equivalent to be located airflow drive assembly in the same one side of horizontal direction (in this embodiment, air filter component 102 and oxygen inlet subassembly 201 all are located airflow drive assembly's left side), be favorable to being connected between airflow drive assembly's air inlet and air filter component 102's gas outlet and the oxygen inlet subassembly 201, avoid setting up too many pipelines, be favorable to integrating of device, the miniaturization sets up.

With continued reference to fig. 5, corresponding to the configuration of the first module 100 above the second module 200, in a preferred implementation, the air outlet of the airflow driving assembly is oriented downward, the air inlet of the main air duct assembly 210 is oriented upward, and the air outlet of the airflow driving assembly is vertically corresponding to and connected with the air inlet of the main air duct assembly 210.

As shown in fig. 5, main airway assembly 210 includes a main airway 211, and main airway 211 includes first and second angularly disposed

airways

212, 213. The second air passage 213 is arranged approximately horizontally, the first air passage 212 is arranged approximately vertically, the air inlet of the first air passage 212 forms the air inlet of the main air passage 211, the air outlet of the first air passage 212 is connected with the air inlet of the second air passage 213, and the air outlet of the second air passage 213 forms the air outlet 214 of the main air passage 211. The air inlet of first air duct 212 is vertically disposed, the air flow driving assembly, that is, the air outlet of turbine mechanism 101, is disposed facing downward, and the air outlet of turbine mechanism 101 is aligned with and connected to the air inlet of first air duct 212.

It can be understood that the air outlet of the air flow driving assembly is correspondingly connected with the air inlet of the main air passage 211 up and down, so that no additional connecting pipeline or pipeline is required to be arranged between the air outlet of the air flow driving assembly and the air inlet of the main air passage 211, the pipeline structure is simplified, the component arrangement of the device is compact, the size is reduced, and the miniaturization design of the device is facilitated.

In this embodiment, both the air outlet 214 of the main air duct 211 and the air inlet of the oxygen inlet assembly 201 face the side of the device. Specifically, referring to FIG. 1, air outlet 214 of main airway 211 is disposed at the front, i.e., front, of the device to facilitate connection of main airway 211 to the corresponding tubing (which is typically the tubing that delivers air from main airway 211 to the vicinity of the patient's nares); the air inlet of the oxygen inlet assembly 201 is disposed at the back of the apparatus to facilitate the connection of the oxygen inlet assembly 201 to the oxygen supply apparatus.

By arranging the air outlet 214 of the main air duct 211 at the front and the air inlet of the oxygen inlet assembly 201 at the back of the apparatus, the interference between the components can be avoided and the aesthetic appearance of the apparatus can be improved.

Wherein the air outlet of the main air passage 211 may be disposed at any position in front thereof. Referring to fig. 1 and 3, in one embodiment, the outlet of the main air path 211 is provided at the center of the front surface of the second module 200 to improve the aesthetic appearance of the device.

In one embodiment, a flow sensor is disposed on the main air passage 211, and the flow sensor may be disposed on an inner wall of the main air passage 211. When gas flows in main air duct 211, the flow rate sensor detects the flow rate of the gas in main air duct 211. By detecting the flow rate of the gas via the flow sensor, an operator can conveniently know whether the flow rate of the gas in main airway 211 meets the requirements of the patient. When the flow rate of the gas is higher or lower than the patient's demand, the operator may make a corresponding flow rate adjustment, for example by adjusting the rotational speed of the turbine mechanism 101 for the purpose of adjusting the flow rate.

In another embodiment, the oxygen cell 202 is disposed on the main air passage 211, and when gas flows in the main air passage 211, the oxygen cell 202 detects the oxygen concentration of the gas in the main air passage 211. By detecting the oxygen concentration of the gas through the oxygen cell 202, it is convenient for the operator to know whether the oxygen concentration of the gas in the main air passage 211 meets the requirement of the patient. When the oxygen concentration of the gas does not match the patient's needs, the oxygen concentration may be adjusted by adjusting a proportional valve or the like of the oxygen inlet assembly 201.

Referring to fig. 4 and 5, in the present embodiment, the oxygen cell 202 is disposed on the rear end of the main air passage 211. Specifically, the oxygen cell 202 is located at a position where the first air passage 212 and the second air passage 213 are connected, and the oxygen cell 202 is disposed at a side of the air inlet of the second air passage 213 which is far from the air outlet 214 thereof, that is, near the rear side of the entire apparatus. Wherein, the sensing end of the oxygen cell 202 is communicated with the inside of the second air channel 213 so as to detect the oxygen concentration in the second air channel 213.

It can be understood that the oxygen cell 202 is integrated in the main air passage 211 and located at the rear end of the main air passage 211, and the space on the side of the air outlet 214 facing away from the main air passage 211 is reasonably utilized, so that the whole device occupies less space and the components are more compact than the form in which the oxygen cell 202 is mounted on the side of the main air passage 211.

Of course, the oxygen cell 202 and the flow sensor may be disposed in the main air passage 211, so that the corresponding indicators of the gas can be monitored comprehensively through the oxygen cell 202 and the flow sensor.

The air filter assembly 102 is connected with the box body 103 into a whole, so that an additional pipeline does not need to be designed, and the device is simpler.

Referring to fig. 6, in order to achieve a further compact arrangement of the apparatus while taking into account balance and aesthetic properties of the entire apparatus.
