Detailed Description

In order to more clearly explain the overall concept of the present invention, the following detailed description is given by way of example in conjunction with the accompanying drawings.

It should be noted that in the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and thus the scope of the present invention is not limited by the specific embodiments disclosed below.

Descriptions in this specification as relating to "first", "second", etc. are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit to any indicated technical feature or quantity. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

Fig. 1 is a schematic diagram of the interconnection between the air circuits of the respiratory therapy apparatus, wherein the respiratory therapy apparatus includes an oxygen supply air circuit 10, the oxygen supply air circuit 10 includes an air supply branch 11 and an oxygen generation branch 12 which are connected to each other, and an air compressor 50 is disposed on the air supply branch 11. When the oxygen supply gas circuit 10 works, air can enter the air supply branch 11 from the air inlet 90 on the left side of the oxygen supply gas circuit 10 in fig. 1 under the action of the air compressor 50, and continuously enters the oxygen generation branch 12 to generate oxygen after passing through the air compressor 50 along the arrow direction in fig. 1, and the generated oxygen is conveyed to a user from the output end of the oxygen generation branch 12 for the user to use.

The existing oxygen supply gas circuit 10 has an air compressor 50 disposed on the gas supply branch 11, the gas supply branch 11 can only provide air for the oxygen generation branch 12, and the air compressor 50 mainly serves to drive the gas to flow. Referring to fig. 2, the suction branch 21 may be connected to the air supply branch 11 at an air inlet end of the air compressor 50, the suction branch 21 has a liquid suction end 211 for a user to use, and after the suction branch 21 is connected to the air supply branch 11, the air compressor 50 may also provide negative pressure for the suction branch 21, so that the liquid suction end 211 can extend into a respiratory tract of the user and suck secretions such as mucus out. The suction branch 21 may be connected to the air supply branch 11 such that the suction branch 21 may generate a negative pressure using the air compressor 50 in the oxygen supply path 10 to perform a suction operation.

Referring to fig. 1, the air outlet end of the air compressor 50 connects the air outlet branch 22 to the air supply branch 11, so that the suction branch 21, the air compressor 50 and the air outlet branch 22 form a complete suction air path 20, and after the air compressor 50 generates negative pressure in the suction branch 21 to suck secretions such as mucus at the liquid extraction end 211, the air passing through the air compressor 50 can be discharged out of the suction air path 20 through the air outlet branch 22. Through setting up exhaust branch 22, can in time discharge the gas that air compressor 50 produced in the suction gas circuit 20, on the one hand make suction gas circuit 20 accomplish and can not cause direct influence to system oxygen branch 12 when attracting the function, only can accomplish at air feed branch 11 and attract the action, thereby on the other hand can avoid attracting the gas that produces directly to get into system oxygen branch 12 as far as possible and cause the pollution.

The suction gas circuit 20 can be matched with the gas supply branch 11 in the oxygen supply gas circuit 10, so that the suction gas circuit 20 and the oxygen supply gas circuit 10 can be integrated in the same machine. The suction gas circuit 20 can utilize the function of the air compressor 50 in the gas supply branch 11, so that the suction gas circuit 20 and the oxygen supply gas circuit 10 can share one air compressor 50, the volume of the whole machine can be reduced to a certain extent, and the cost of using a plurality of compressors in a plurality of existing devices is reduced.

After the suction branch 21 and the exhaust branch 22 of the suction air path 20 are connected to the air supply branch 11, the respiratory therapy apparatus can realize multiple working modes, for example, the respiratory therapy apparatus performs an oxygen supply function when the air supply branch 11 and the oxygen generation branch 12 are communicated with the air compressor 50, the respiratory therapy apparatus performs an suction function when the suction branch 21 and the exhaust branch 22 are communicated with the air compressor 50, the air compressor 50 does not stop working or restart when switching between the two functions, time consumed by restarting each function is reduced, therefore, switching efficiency between the oxygen supply function and the suction function is improved, instantaneous switching can be completed, rapid matching use between multiple functions can be realized, and the connection between the two functions is better.

The oxygen generation function and the attraction function can be integrated only through the air supply branch 11 and the air compressor 50, and the attraction branch 21 and the oxygen generation branch 12 are respectively connected into the air supply branch, so that the attraction function and the oxygen generation function can work independently and cooperatively. For example, when the user normally uses the oxygen generation function, the user needs to attract the function to clean the respiratory tract, at this time, the air supply branch 11 and the oxygen generation branch 12 can be disconnected temporarily, and the attraction branch 21 and the exhaust branch 22 are connected to the air supply branch 11, so that the rapid switching of the functions is completed, and more treatment scenes can be adapted. And the switching can be realized only by controlling the switching communication of the pipelines, and the operation is simple.

Regarding the manner of switching between the oxygen supply function and the suction function, in the specific embodiment shown in fig. 2, three-way valves are provided between the suction branch 21 and the gas supply branch 11, and between the exhaust branch 22 and the gas supply branch 11, and taking fig. 2 as an example, the three-way valve connecting the suction branch 21 and the gas supply branch 11 in fig. 2 is an intake three-way valve 71, the intake three-way valve 71 includes A, B, C three joints, the three-way valve connecting the exhaust branch 22 and the gas supply branch 11 in fig. 2 is an exhaust three-way valve 72, and the exhaust three-way valve 72 includes X, Y, Z three joints. When the joints a and B of the intake three-way valve 71 are connected and the joints X and Y of the exhaust three-way valve 72 are connected, the air in the air inlet 90 of the air supply branch 11 can pass through the intake three-way valve 71, the air compressor 50 and the exhaust three-way valve 72 and then enter the oxygen generation branch 12 to generate oxygen, so as to complete the oxygen supply function. When there is a demand for using the suction function, the joints a and C of the intake three-way valve 71 are connected, and the joints X and Z of the exhaust three-way valve 72 are connected, so that the gas at the gas inlet 90 of the gas supply branch 11 cannot pass through the intake three-way valve 71, and the gas at the liquid suction end 211 of the suction branch 21 is sucked by the air compressor 50, passes through the intake three-way valve 71, the air compressor 50, and the exhaust three-way valve 72, and then enters the exhaust branch 22, and is discharged. The three-way valve is used for simply switching between the two functional gas paths, the three-way valve can complete switching only through one-step operation, switching action is rapid, switching efficiency among multiple functions can be improved, and cost is low. For example, the two-position three-way valve is intuitive to operate and is not easy to cause misoperation. The leakproofness of three-way valve is better, can adapt to comparatively frequent switching operation, can guarantee the sealed effect when gaseous passing through simultaneously.

Meanwhile, the three-way valve can limit the gas to flow along only one gas path, for example, when the suction function is turned on, the gas at the pumping end 211 can only enter the three-way valve from the joint C of the gas inlet three-way valve 71, the gas is discharged from the three-way valve from the joint a of the gas inlet three-way valve 71 and then passes through the air compressor 50, the gas cannot enter the gas inlet 90 in the gas supply branch 11 through the joint B, the full utilization of the gas can be ensured, and the gas is prevented from entering other branches as much as possible to cause adverse effects. Similarly, the controllable air current of exhaust three-way valve 72 flows into exhaust branch 22 via joint Y and joint Z, and does not make gas flow into oxygen generation branch 12 via joint X, thus ensuring effective rapid discharge of gas in the suction gas path and preventing gas from influencing oxygen generation branch 12 in oxygen generation branch 12.

It is to be understood that the intake three-way valve 71 may be a confluence valve and the exhaust three-way valve 72 may be a split valve. Or the air pipe of the suction branch 21 can be inserted and matched with the air inlet end of the air compressor 50. Further alternatively, the branch lines of the air supply line and the suction branch line 21 may be provided with switches capable of opening and closing the air pipes. This application does not do the restriction to the oxygen suppliment function and attracts the switching mode between the function of supplying, as long as can accomplish the switching function can.

The three-way valve is further optimized in that the three-way valve is an electromagnetic valve, the two three-way valves can be switched and controlled through one key of the respiratory therapy device, the function can be switched immediately after the two three-way valves are switched simultaneously, the switching efficiency is higher, and the operation is simple.

Regarding the functions of the respiratory therapy device, the respiratory therapy device may further include an atomizing branch 31, as shown in fig. 3, the atomizing branch 31 is connected to the air outlet end of the air compressor 50 in the air supply branch 11, and the atomizing branch 31 includes an atomizing cup 311 and an atomizing end 312 for the user along the air flow direction (as shown in the arrow direction in fig. 3). When the atomization function is needed, the joints a and B of the air inlet three-way valve 71 are communicated, and the joints X and Y of the air outlet three-way valve 72 are communicated, at this time, under the action of the air compressor 50, air enters from the air inlet 90 of the air supply branch 11, and enters the atomization branch 31 after passing through the air inlet three-way valve 71, the air compressor 50 and the air outlet three-way valve 72, so that the air compressor 50 can help the liquid in the atomization cup 311 to be atomized, and the atomized liquid can be output from the atomization end 312. The atomization function can also use the air compressor 50 together with the oxygen supply function and the suction function, thereby realizing the integration of three functions, the humidification function, the oxygen supply function and the suction function can be integrated in the same complete machine, on one hand, the shared air compressor 50 can reduce the volume of the respiratory therapy device as much as possible, the cost is reduced, on the other hand, the air compressor 50 is always in the running state when the respiratory therapy device is switched among various functions, the rapid switching can be completed, and the switching linkage between the functions is better. For example, before inhaling the phlegm operation to the user, carry out the humidification to user's respiratory track through atomizing gas circuit 30 to make mucus dilute to the state of being convenient for the suction, then start through the switching of three-way valve and attract gas circuit 20, in order to in time attract taking out the mucus in user's respiratory track, prevent that mucus from staying in user's respiratory track and causing danger.

The further optimization of the atomization branch 31 is that the atomization branch 31 is connected to the air supply branch 11 after the exhaust three-way valve 72, and as shown in fig. 3, in order to avoid as much as possible that the gas generated when the suction branch 21 operates enters the atomization branch 31 and affects or pollutes the atomization branch 31, an interface between the atomization branch 31 and the air supply branch 11 is disposed after the exhaust three-way valve 72, and the atomization branch can be connected to the air compressor 50 after the exhaust branch 22 discharges all the gas of the suction branch 21, so as to ensure that the air entering the atomization branch 31 is relatively clean as much as possible.
