本发明涉及医疗器械技术领域，特别涉及一种辅助治疗呼吸装置。The invention relates to the technical field of medical devices, in particular to an auxiliary therapy breathing device.
背景技术Background technique
常规的呼吸装置用于给患者输送由氧气和空气组成的合适的混合气，以 便于对患者进行例如完全人工的呼吸和/或至少部分地支持他的呼吸。然而， 在常规的呼吸装置中始终需要必须通过气压瓶或者例如在医院中的固定的压 缩空气供应系统来提供的压缩空气供应。因此，常规的呼吸装置不能移动使 用，也即不能没有气压瓶或者压缩空气供应系统，从而常规呼吸装置的使用 可能性也限制为有限的环境中。Conventional breathing apparatus are used to deliver a suitable mixture of oxygen and air to a patient in order to perform, for example, complete artificial respiration of the patient and/or to at least partially support his respiration. However, in conventional breathing apparatus there is always a need for a compressed air supply which has to be provided by means of a pneumatic cylinder or a fixed compressed air supply system, for example in a hospital. Conventional breathing apparatus therefore cannot be used mobile, i.e. without a gas cylinder or a compressed air supply system, so that the possibilities of use of conventional breathing apparatus are also limited to limited environments.

The oxygen delivery tube 40 is discharged from the breathing mask connected with the oxygen delivery tube 40 free ends.
其中，所述氧气管路10的一端为氧气入口，所述氧气管路10上设有压 力传感器11，所述压力传感器11用于监测所述氧气入口处的压力；所述控制 器用于接收所述压力传感器11的压力信号，并与预设压力值进行比对后，发 出控制信号；所述空气管路20的一端为空气入口，所述空气管路20上设有 接收所述压力信号的涡轮风机21，所述涡轮风机21用于通过所述空气入口向 外部环境抽吸空气，并根据所述压力信号进行调节转速；所述连通件30内具 有混合腔，所述混合腔分别与所述空气管路20以及氧气管路10的另一端连 通，用于将氧气管路10所供应的氧气以及来自所述涡轮风机21所抽吸的空 气进行混合，并将混合后的气体通过一输出接口321输出；所述输氧管40的 一端插接在所述连通件30的输出接口321上，另一端与一呼吸面罩连接。Wherein, one end of the oxygen pipeline 10 is an oxygen inlet, and the oxygen pipeline 10 is provided with a pressure sensor 11, and the pressure sensor 11 is used to monitor the pressure at the oxygen inlet; the controller is used to receive the The pressure signal of the pressure sensor 11 is compared with the preset pressure value to send a control signal; one end of the air pipeline 20 is an air inlet, and the air pipeline 20 is provided with a device for receiving the pressure signal Turbo fan 21, the turbo fan 21 is used to suck air to the external environment through the air inlet, and adjust the speed according to the pressure signal; there is a mixing chamber in the connecting member 30, and the mixing chamber is respectively connected with the The other end of the air pipeline 20 and the oxygen pipeline 10 is connected to mix the oxygen supplied by the oxygen pipeline 10 and the air sucked by the turbo blower 21, and the mixed gas is passed through an output The interface 321 is output; one end of the oxygen delivery tube 40 is plugged into the output interface 321 of the connecting piece 30, and the other end is connected with a breathing mask.
根据本发明的辅助治疗呼吸装置，当氧气管路10上的压力传感器11压 力降低时，控制器自动控制涡轮风机21提高转速，从而提高空气管路20中 空气的流量和压力，进而确保输氧管40中混合气体的流量和压力使其处于所 需要的范围内；当氧气管路10上的压力传感器11压力升高时，控制器自动 控制涡轮风机21降低转速，从而降低空气管路20中空气的流量和压力，进 而确保输氧管40中混合气体的流量和压力处于所需要的范围内。According to the assisted therapeutic breathing apparatus of the present invention, when the pressure of the pressure sensor 11 on the oxygen pipeline 10 decreases, the controller automatically controls the turbo blower 21 to increase the rotating speed, thereby increasing the flow and pressure of the air in the air pipeline 20, thereby ensuring that the oxygen delivery tube The flow and pressure of the mixed gas in 40 make it within the required range; when the pressure of the pressure sensor 11 on the oxygen pipeline 10 increases, the controller automatically controls the turbo blower 21 to reduce the speed, thereby reducing the air in the air pipeline 20. flow and pressure, and then ensure that the flow and pressure of the mixed gas in the oxygen pipe 40 are within the required range.
在本发明的一个实施例中，所述连通件30包括主体31、连接管32以及 弹性隔膜33。In one embodiment of the present invention, the connecting member 30 includes a main body 31 , a connecting pipe 32 and an elastic diaphragm 33 .
所述主体31为圆筒状且一端封闭另一端敞开结构，所述氧气管路10的 另一端以及空气管路20的另一端分别连通至所述主体31侧壁的相对两侧； 所述连接管32同轴穿设在所述主体31内，且内端从所述主体31的敞开端穿 出，外端从所述主体31的封闭端穿出而形成所述输出接口321；所述弹性隔 膜33的边缘密封连接在所述主体31的敞开端，弹性隔膜33的中部抵压在所 述连接管32的内端上，从而弹性隔膜33与所述主体31的内壁以及所述连接 管32的外壁共同形成环形的所述混合腔38；当所述氧气管路10所供应的氧 气以及来自所述涡轮风机21所抽吸的空气进入所述混合腔38后，所形成的 混合气体可通过推动弹性隔膜33而从所述连接管32内端进入。The main body 31 is cylindrical with one end closed and the other end open. The other end of the oxygen pipeline 10 and the other end of the air pipeline 20 are respectively connected to the opposite sides of the side wall of the main body 31; the connection The tube 32 is coaxially installed in the main body 31, and the inner end passes through the open end of the main body 31, and the outer end passes through the closed end of the main body 31 to form the output interface 321; The edge of the diaphragm 33 is sealingly connected to the open end of the main body 31, and the middle part of the elastic diaphragm 33 is pressed against the inner end of the connecting pipe 32, so that the elastic diaphragm 33 is in contact with the inner wall of the main body 31 and the connecting pipe 32 The outer walls together form the annular mixing chamber 38; when the oxygen supplied by the oxygen pipeline 10 and the air sucked from the turbo blower 21 enter the mixing chamber 38, the formed mixed gas can pass through Push the elastic diaphragm 33 to enter from the inner end of the connecting pipe 32 .

That is to say, when oxygen and air enter the annular mixing chamber 38, they are mixed in a helical manner, so as to facilitate the mixing of the gases and the mixed gas to enter the connecting pipe 32 quickly.
在本发明的一个实施例中，所述空气管路20还包括有一过滤器22，所述 过滤器22包括壳体221以及设置于所述壳体221内的滤芯；所述壳体221具 有相对的第一端222和第二端223，所述第一端222内设有若干进气孔2221 以形成所述空气入口，所述第二端223与所述空气管路20的端部连通；所述 滤芯包括由第一端222向第二端223方向依次设置的第一泡沫层224、第一滤 芯层225、吸水层226、第二泡沫层227以及第二滤芯层228。In one embodiment of the present invention, the air pipeline 20 also includes a filter 22, the filter 22 includes a housing 221 and a filter element arranged in the housing 221; the housing 221 has a relatively The first end 222 and the second end 223 of the first end 222 are provided with several air inlets 2221 to form the air inlet, and the second end 223 communicates with the end of the air pipeline 20; The filter element includes a first foam layer 224 , a first filter element layer 225 , a water-absorbing layer 226 , a second foam layer 227 and a second filter element layer 228 arranged in sequence from the first end 222 to the second end 223 .
也就是说，进入壳体221内部的空气是从第一端222向第二端223流动 的，而且，在流动过程中，需要依次穿过第一泡沫层224、第一滤芯层225、 吸水层226、第二泡沫层227以及第二滤芯层228，通过第一泡沫层224和第 二泡沫层227可以吸附空气的油雾等，同时，可以使得吸入的空气能够均匀 的进入后续的第一滤芯层225、吸水层226和第二滤芯层228，通过第一滤芯 层225则可以过滤空气中的污染物(包括粉尘颗粒、病菌等)，再通过吸水层226则可以吸附除去空气中的水分，进而得到洁净清新的空气。That is to say, the air entering the inside of the casing 221 flows from the first end 222 to the second end 223, and, during the flow, it needs to pass through the first foam layer 224, the first filter element layer 225, the water-absorbing layer in sequence 226, the second foam layer 227 and the second filter element layer 228, through the first foam layer 224 and the second foam layer 227, the oil mist of the air can be absorbed, and at the same time, the inhaled air can evenly enter the subsequent first filter element Layer 225, water-absorbing layer 226 and the second filter element layer 228 can filter the pollutants (comprising dust particles, germs, etc.) And then get clean and fresh air.
优选地，所述氧气管路10和空气管路20上还分别设置有一单向阀12、 23，所述空气管路20上的单向阀23位于所述涡轮风机21与所述连通件30 之间，并允许空气从涡轮风机21向连通件30方向流动。而空气管路20上的 单向阀12也是只允许空气从氧气入口向连通件30方向流动，也就是说，氧 气管路10和空气管路20上的氧气和空气只能流入混合腔38而不能从混合腔 38流向氧气管路10和空气管路20内。Preferably, the oxygen pipeline 10 and the air pipeline 20 are also provided with a one-way valve 12, 23 respectively, and the one-way valve 23 on the air pipeline 20 is located between the turbo blower 21 and the communicating member 30. between, and allow the air to flow from the turbo blower 21 to the connecting piece 30. And the one-way valve 12 on the air line 20 also only allows air to flow from the oxygen inlet to the connecting piece 30, that is to say, the oxygen and air on the oxygen line 10 and the air line 20 can only flow into the mixing chamber 38 and not It cannot flow from the mixing chamber 38 into the oxygen line 10 and the air line 20 .
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围， 凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构 变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范 围内。The above is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Under the inventive concept of the present invention, the equivalent structural transformation made by using the description of the present invention and the contents of the accompanying drawings, or direct/indirect use All other relevant technical fields are included in the patent protection scope of the present invention.
