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 anair supply branch 11 and anoxygen generation branch 12 which are connected to each other, and anair compressor 50 is disposed on theair supply branch 11. When the oxygen supply gas circuit 10 works, air can enter theair supply branch 11 from theair inlet 90 on the left side of the oxygen supply gas circuit 10 in fig. 1 under the action of theair compressor 50, and continuously enters theoxygen generation branch 12 to generate oxygen after passing through theair compressor 50 along the arrow direction in fig. 1, and the generated oxygen is conveyed to a user from the output end of theoxygen generation branch 12 for the user to use.
The existing oxygen supply gas circuit 10 has anair compressor 50 disposed on thegas supply branch 11, thegas supply branch 11 can only provide air for theoxygen generation branch 12, and theair compressor 50 mainly serves to drive the gas to flow. Referring to fig. 2, thesuction branch 21 may be connected to theair supply branch 11 at an air inlet end of theair compressor 50, thesuction branch 21 has aliquid suction end 211 for a user to use, and after thesuction branch 21 is connected to theair supply branch 11, theair compressor 50 may also provide negative pressure for thesuction branch 21, so that theliquid suction end 211 can extend into a respiratory tract of the user and suck secretions such as mucus out. Thesuction branch 21 may be connected to theair supply branch 11 such that thesuction branch 21 may generate a negative pressure using theair compressor 50 in the oxygen supply path 10 to perform a suction operation.
Referring to fig. 1, the air outlet end of theair compressor 50 connects theair outlet branch 22 to theair supply branch 11, so that thesuction branch 21, theair compressor 50 and theair outlet branch 22 form a completesuction air path 20, and after theair compressor 50 generates negative pressure in thesuction branch 21 to suck secretions such as mucus at theliquid extraction end 211, the air passing through theair compressor 50 can be discharged out of thesuction air path 20 through theair outlet branch 22. Through setting upexhaust branch 22, can in time discharge the gas thatair compressor 50 produced in thesuction gas circuit 20, on the one hand makesuction gas circuit 20 accomplish and can not cause direct influence tosystem oxygen branch 12 when attracting the function, only can accomplish atair feed branch 11 and attract the action, thereby on the other hand can avoid attracting the gas that produces directly to get intosystem oxygen branch 12 as far as possible and cause the pollution.
Thesuction gas circuit 20 can be matched with thegas supply branch 11 in the oxygen supply gas circuit 10, so that thesuction gas circuit 20 and the oxygen supply gas circuit 10 can be integrated in the same machine. Thesuction gas circuit 20 can utilize the function of theair compressor 50 in thegas supply branch 11, so that thesuction gas circuit 20 and the oxygen supply gas circuit 10 can share oneair 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 thesuction branch 21 and theexhaust branch 22 of thesuction air path 20 are connected to theair supply branch 11, the respiratory therapy apparatus can realize multiple working modes, for example, the respiratory therapy apparatus performs an oxygen supply function when theair supply branch 11 and theoxygen generation branch 12 are communicated with theair compressor 50, the respiratory therapy apparatus performs an suction function when thesuction branch 21 and theexhaust branch 22 are communicated with theair compressor 50, theair 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 theair supply branch 11 and theair compressor 50, and theattraction branch 21 and theoxygen 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, theair supply branch 11 and theoxygen generation branch 12 can be disconnected temporarily, and theattraction branch 21 and theexhaust branch 22 are connected to theair 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 thesuction branch 21 and thegas supply branch 11, and between theexhaust branch 22 and thegas supply branch 11, and taking fig. 2 as an example, the three-way valve connecting thesuction branch 21 and thegas 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 theexhaust branch 22 and thegas 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 theair inlet 90 of theair supply branch 11 can pass through the intake three-way valve 71, theair compressor 50 and the exhaust three-way valve 72 and then enter theoxygen 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 thegas inlet 90 of thegas supply branch 11 cannot pass through the intake three-way valve 71, and the gas at theliquid suction end 211 of thesuction branch 21 is sucked by theair compressor 50, passes through the intake three-way valve 71, theair compressor 50, and the exhaust three-way valve 72, and then enters theexhaust 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 pumpingend 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 theair compressor 50, the gas cannot enter thegas inlet 90 in thegas 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 intoexhaust branch 22 via joint Y and joint Z, and does not make gas flow intooxygen generation branch 12 via joint X, thus ensuring effective rapid discharge of gas in the suction gas path and preventing gas from influencingoxygen generation branch 12 inoxygen 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 thesuction branch 21 can be inserted and matched with the air inlet end of theair compressor 50. Further alternatively, the branch lines of the air supply line and thesuction 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 theair compressor 50 in theair supply branch 11, and the atomizing branch 31 includes anatomizing cup 311 and anatomizing 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 theair compressor 50, air enters from theair inlet 90 of theair supply branch 11, and enters the atomization branch 31 after passing through the air inlet three-way valve 71, theair compressor 50 and the air outlet three-way valve 72, so that theair compressor 50 can help the liquid in theatomization cup 311 to be atomized, and the atomized liquid can be output from theatomization end 312. The atomization function can also use theair 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 sharedair compressor 50 can reduce the volume of the respiratory therapy device as much as possible, the cost is reduced, on the other hand, theair 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 attractgas 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.
Not only can accomplish the switching between the different functions between a plurality of functions, still can realize using simultaneously between a plurality of functions, can see in by figure 3, atomizing branch road 31 is connected after exhaust three-way valve 72 with system oxygen branch road (can see simultaneously figure 1), when the air compressor is pneumatic, system oxygen branch road can act on with atomizing branch road 31 simultaneously, airfeed branch road 11 can be simultaneously for system oxygen branch road and atomizing branch road 31 air feed promptly, thereby make oxygen feed function and atomizing function can use simultaneously, be favorable to improving treatment, when using the oxygen feed function alone, can close atomizing branch road 31 alone.
The further optimization of the atomization branch 31 is that the atomization branch 31 is connected to theair 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 thesuction branch 21 operates enters the atomization branch 31 and affects or pollutes the atomization branch 31, an interface between the atomization branch 31 and theair supply branch 11 is disposed after the exhaust three-way valve 72, and the atomization branch can be connected to theair compressor 50 after theexhaust branch 22 discharges all the gas of thesuction branch 21, so as to ensure that the air entering the atomization branch 31 is relatively clean as much as possible.

In an optional implementation, the output of systemoxygen branch road 12 still is provided withhybrid chamber 81 andhumidifying chamber 82, breathe the output ofgas circuit 40 and inserthybrid chamber 81, the air volume that thegas circuit 40 produced and the oxygen that systemoxygen branch road 12 produced mix inhybrid chamber 81, thereby form the higher air of oxygen content, this higher air of oxygen content gets into the human body after humidifyingchamber 82 humidifying, humidifyingchamber 82 can carry out the humidifying to the air, and then prevent that dry air from causing the injury to the mucous membrane etc. of human body. The breathing function and the oxygen supply function are practical at the same time, and good effects can be achieved on life maintenance or rehabilitation of users.

Anegative pressure sensor 214 and apressure regulating valve 215 are further disposed behind theair suction filter 213, thenegative pressure sensor 214 can monitor the air pressure signal in thesuction branch 21 in real time, when the air pressure in thesuction branch 21 is low, thenegative pressure sensor 214 can output a pressure regulating signal, and thepressure regulating valve 215 can be controlled by the pressure regulating signal to supply air to thesuction branch 21, so as to maintain the air pressure in thesuction branch 21 stable, and prevent the mucus in theliquid storage part 212 from being sucked out and polluted due to the unstable air pressure in thesuction branch 21. Meanwhile, thepressure regulating valve 215 can regulate the air pressure on thesuction branch 21 in real time, so that the air pressure on thesuction branch 21 maintains the optimal suction pressure on theliquid pumping end 211, thereby improving the suction efficiency.
