[0042] The utility model will be further described below with reference to the drawings.

[0043] As Figure 1 shown, according to the first aspect of the utility model, the utility model provides an outlet assembly 11 for ventilation therapy equipment, which is used to deliver the treatment gas generated by the ventilation therapy equipment into the ventilation pipeline, and the ventilation pipeline is generally connected with the breathing mask worn by the patient, so that the treatment gas can be provided for the patient to use.The ventilation therapy equipment generally includes a gas source, and the gas source includes an input end communicated with the environment outside the equipment, and also includes an output end for outputting the high-pressure airflow generated by the gas source.In the ventilation therapy equipment configured with a humidification device (water tank), the output end of the gas source is communicated with the input end of the humidification device (water tank), and the high-pressure airflow generated by the gas source is outputted after being humidified by the liquid in the water tank.In the ventilation therapy equipment not configured with a humidification device (water tank), the output end of the gas source directly outputs the high-pressure airflow generated without humidification.

[0044] Specifically, the outlet assembly 11 includes a first connecting part 111 with elasticity and a second connecting part 112 with elasticity, the first connecting part 111 is used to be in fluid communication with the airflow output end (for example, the air outlet end of the water tank 1 as shown) of the ventilation therapy equipment, and the second connecting part 112 is in fluid communication with the first connecting part 111 and is used to be in fluid communication with the ventilation pipeline (not shown) of the ventilation therapy equipment. Figure 2

[0045] Among them, the first connecting part 111 and the second connecting part 112 are both formed by elastic material, that is, both have certain elastic deformation capacity, and can correspondingly occur elastic expansion to store energy or self-recovery to release energy.

[0046] ​When the first connecting portion 111 and the second connecting portion 112 flow with the treatment fluid of the ventilation treatment device (the pressure range of the treatment fluid of the ventilation treatment device is, for example, 4-25 cmH2O or 4-30 cmH2O), if the pressure of the treatment fluid is high (for example, the pressure is 20 cmH2O), the first connecting portion 111 and the second connecting portion 112 can store the gas pressure by the elastic expansion characteristics of themselves to slow down the flow rate of the gas with high pressure, so as to effectively eliminate the noise generated by the gas; or if the pressure of the treatment fluid is low (for example, the pressure is 4 cmH2O), the first connecting portion 111 and the second connecting portion 112 can compensate for the lack of pressure of the gas with low pressure by the energy stored by the previous expansion, so as to slow down the shrinkage phenomenon, and also achieve the purpose of eliminating the noise generated by the gas.

[0047] Therefore, the first connecting portion 111 and the second connecting portion 112 have certain self-recovery characteristics, so that when used in various environments such as high frequency, high temperature, low temperature, etc., the elastic material can absorb the noise generated by the vibration of the gas flow, so as to effectively eliminate the noise, thereby making the application range of the outlet assembly 11 wider.

[0048] Preferably, the first connecting portion 111 and the second connecting portion 112 are made of elastic material. For example, the first connecting portion 111 and the second connecting portion 112 are both made of silica gel or the first connecting portion 111 and the second connecting portion 112 are both made of rubber. Especially in the field of ventilation treatment, the use of silica gel material can ensure the safety of use. The first connecting portion 111 and the second connecting portion 112 can be made of elastic material with different hardness or thickness, or can be made of elastic material with the same hardness or thickness.

[0049] Further, the outlet assembly 11 further comprises a communication portion 113 with a curved cross section, the communication portion 113 is located between the first connecting portion 111 and the second connecting portion 112 and is in fluid communication with the first connecting portion 111 and the second connecting portion 112 respectively, and the communication portion 113 can be configured as a curved structure to reduce the impedance of the gas flow through the outlet assembly 11.

[0050] Among them, the communication portion 113, the first connecting portion 111 and the second connecting portion 112 are integrally formed structures, and the communication portion 113 has elasticity. That is, the outlet assembly 11 as a whole is an integrally formed structure with elasticity, so as to be elastically expanded or self-recovered under the action of the treatment fluid.

[0051] The first connecting portion 111, the second connecting portion 112 and the communication portion 113 can be configured as a pipe structure with a circular radial cross section, or a pipe structure with an elliptical, rectangular, special-shaped or the like radial cross section.

[0052] The overall length of the outlet component 11 can be set as needed. For example, the sum of the lengths of the first connecting part 111, the connecting part 113, and the second connecting part 112 is 0.5mm-300mm.

[0053] The wall thickness of the outlet component 11 can be set as needed. For example, the wall thickness of one or more of the first connecting part 111, the connecting part 113, and the second connecting part 112 can be 0.5mm-100mm.

[0054] Furthermore, one or both of the first connecting portion 111 and the second connecting portion 112 are provided with one or more of the following: a shock-absorbing support structure, a fixing structure 114, and a temperature measuring structure 115. For example... Figure 1 As shown, a fixing structure 114 is provided on the first connecting part 111. The fixing structure 114 can be constructed as a flange or other structural form to fix it to the airflow output end of the ventilation therapy device. When the ventilation therapy device includes a humidification device (water tank) for humidifying the therapeutic gas, the airflow output end of the humidification device (water tank) serves as the airflow output end of the ventilation therapy device. When the ventilation therapy device does not include a humidification device (water tank), the output end of the gas source used to generate a higher pressure airflow serves as the airflow output end.

[0055] The second connecting part 112 can also be provided with a fixing structure 114, which can be fixed to the air outlet connector 123 of the ventilation therapy device. The air outlet connector 123 can be easily plugged into the ventilation pipeline.

[0056] According to a second aspect of the present invention, the present invention provides a ventilation therapy device, including the outlet component 11 for the ventilation therapy device described above, and further including an airflow output end and a ventilation pipeline, wherein the airflow output end is in fluid communication with the ventilation pipeline through the outlet component 11.

[0057] Example 1

[0058] like Figure 2 As shown, the ventilation therapy device includes a humidification device, which includes a water tank 1. The water tank 1 includes a first housing 12 and a second housing 14, which are fastened together.

[0059] The water tank 1 includes a first air inlet 121 and a first air outlet 122 located on the first housing 12, as well as a flexible water tank air inlet pipe 133 and a flexible water tank air outlet pipe 134 located inside the water tank 1. The water tank air inlet pipe 133 is connected to the first air inlet 121, and the water tank air outlet pipe 134 is connected to the first air outlet 122. The first air outlet 122 is configured as the airflow output end of the ventilation therapy device.

[0060] like Figure 2As shown, and please combine Figure 10 The water tank air inlet pipe 133 and the water tank air outlet pipe 134 are formed as a first air flow pipe 13. The first air flow pipe 13 is located in the internal space formed after the first shell 12 and the second shell 14 are buckled to each other. Therefore, it can be known that the high-pressure air flow generated by the air source can enter the water tank 1 through the first air inlet 121 and the water tank air inlet pipe 133 in turn after the output end of the air source, and is output from the water tank 1 after being humidified in the water tank 1 and passing through the water tank air outlet pipe 134 and the first air outlet 122 in turn.

[0061] The first air outlet 122 is in fluid communication with the first connecting part 111, so that the humidified (heated) gas can flow through the first connecting part 111 and the second connecting part 112.

[0062] The noise reduction principle of the first air flow pipe 13 is similar to that of the outlet assembly 11, that is, the first air flow pipe 13 is also configured to store energy when the pressure of the treatment fluid flowing in the inside thereof is high (for example, the pressure is 20 cmH2O) and to release energy when the pressure of the treatment fluid flowing in the inside thereof is low (for example, the pressure is 4 cmH2O). That is to say, when the first air flow pipe 13 can store the gas pressure by its elastic expansion characteristics to slow down the flow rate of the high-pressure gas, thereby effectively eliminating the noise generated by the gas; or the first air flow pipe 13 can make up for the lack of pressure of the low-pressure gas by the energy stored by the previous expansion, thereby slowing down the contraction phenomenon, and also achieving the purpose of eliminating the noise generated by the gas.

[0063] Therefore, the first air flow pipe 13 has certain self-recovery characteristics, so that it can be used in various environments such as high frequency, high temperature and low temperature. By using the characteristics of the elastic material that can absorb the noise generated by the vibration of the flowing air, the noise can be effectively eliminated, so that the application range is wider.

[0064] As shown in the drawings, Figure 10 As shown, a structure of the first air flow pipe 13 is shown, which is roughly a U-shaped tubular structure. The water tank air inlet pipe 133 is in fluid communication with the water tank air outlet pipe 134 through the U-shaped structure. The end of the water tank air inlet pipe 133 is provided with an air inlet hole 131, and the air inlet hole 131 is in fluid communication with the first air inlet 121. The end of the water tank air outlet pipe 134 is provided with an air outlet hole 132, and the air outlet hole 132 is in fluid communication with the first air outlet 122.

[0065] It can be understood that the first air flow pipe 13 can also have other structure forms, and the present application does not intend to limit the shape thereof.

[0066] Further, the ventilation therapy device further comprises an air source 2, which can be in the form of a noise reduction device or the like, and which is internally provided with a fan structure for sucking air from the external environment into the internal part, pressurizing the air and then outputting the air. For the ventilation therapy device without the humidifying device (water tank), the output end of the air source is the air flow output end of the ventilation therapy device; for the ventilation therapy device with the humidifying device (water tank), the output end of the air source is in communication with the air flow input end of the humidifying device (water tank), i.e., in communication with the first air inlet 121, so as to deliver the air flow with higher pressure to the water tank 1.

[0067] As shown in Figure 2 , the air source 2 comprises a second air inlet 211 and a second air outlet 212, wherein the second air inlet 211 is the input end of the air source, and the second air outlet 212 is the output end of the air source. The air outside the air source 2 can enter the fan assembly 21 inside the air source 2 through the second air inlet 211 for pressurization. When the ventilation therapy device is provided with the humidifying device (water tank), the second air outlet 212 is in fluid communication with the first air inlet 121 through the second air flow pipe 22. As shown in Figure 2 , the second air outlet 212 is in fluid communication with one side of the second air flow pipe 22, and the other side of the second air flow pipe 22 is in fluid communication with the first air inlet 121, so that the air pressurized by the fan assembly 21 can flow into the first air inlet 121 through the second air outlet 212 and the second air flow pipe 22, and then into the water tank 1.

[0068] The noise reduction principle of the second air flow pipe 22 is similar to that of the outlet assembly 11, i.e., the second air flow pipe 22 is also configured to store energy when the pressure of the treatment fluid flowing inside it is high (e.g., the pressure is 20 cmH2O) and to release energy when the pressure of the treatment fluid flowing inside it is low (e.g., the pressure is 4 cmH2O). That is, when the second air flow pipe 22 can store the pressure of the gas by its elastic expansion characteristics to slow down the flow rate of the gas with high pressure, the noise generated by the gas can be effectively eliminated; or the second air flow pipe 22 can compensate for the lack of pressure of the gas with low pressure by the energy stored by the previous expansion, so as to slow down the contraction phenomenon, and also achieve the purpose of eliminating the noise generated by the gas.

[0069] Therefore, the second air flow pipe 22 has certain self-recovery characteristics, so that it can be used in various environments such as high frequency, high temperature and low temperature, and can effectively eliminate noise by absorbing the noise generated by the vibration of the flowing air flow by using the elastic material, so as to make it more widely applicable.

[0070] Further, as shown in Figure 2As shown, the ventilation therapy device further comprises a third air flow tube 23 having elasticity, which is in fluid communication with the external environment of the ventilation therapy device and the air source 2 respectively. More specifically, one end of the third air flow tube 23 is in communication with the external environment of the ventilation therapy device; the other end of the third air flow tube 23 is in fluid communication with the second air inlet 211 of the air source 2, so that air can enter the fan assembly 21 in the air source 2 through the second air inlet 211 via the third air flow tube 23.

[0071] The noise reduction principle of the third air flow tube 23 is similar to that of the outlet assembly 11, that is, the third air flow tube 23 is also configured to elastically expand to store energy when the pressure of the treatment fluid flowing in its interior is high (for example, the pressure is 20 cmH2O), and to restore itself to release energy when the pressure of the treatment fluid flowing in its interior is low (for example, the pressure is 4 cmH2O). That is, when the third air flow tube 23 can store the gas pressure by its own elastic expansion characteristics to slow down the flow rate of the gas with high pressure, thereby effectively eliminating the noise generated by the gas; or the third air flow tube 23 can make up for the lack of pressure of the gas with low pressure by the energy stored by the previous expansion, so as to slow down the contraction phenomenon, and also achieve the purpose of eliminating the noise generated by the gas.

[0072] The first air flow tube 13, the second air flow tube 22 and the third air flow tube 23 can be made of the same elastic material, or can be made of different elastic materials. The elastic material described herein can be silicone or rubber.

[0073] The flow path of the gas in the ventilation therapy device configured with the humidification device (water tank) is that the gas enters the second air inlet 211 through the third air flow tube 23, flows through the fan assembly 21, and is output to the second air flow tube 22 through the second air outlet 212, enters the first air inlet 121 from the second air flow tube 22 to enter the water tank 1 for humidification, and the gas in the water tank 1 flows to the outlet assembly 11 for output under the guidance of the first air flow tube 13.

[0074] Therefore, when the ventilation therapy device is in use, when the air source 2 is started, the third air flow tube 23 of the air source 2 starts to intake air at high speed when the patient inhales, so that negative pressure is generated in the third air flow tube 23, and due to the elastic properties of the third air flow tube 23, the pipe closure phenomenon caused by negative pressure can be reduced and the noise caused by the vibration can be effectively eliminated.

[0075] Furthermore, high-pressure gas will pass through the second outlet 212 and the second airflow pipe 22 of the gas source 2. The gas passes through the second airflow pipe 22, the first airflow pipe 13 and the outlet component 11 in sequence. Due to the elasticity of the second airflow pipe 22, the first airflow pipe 13 and the outlet component 11, the gas pressure can be stored by expansion, thereby slowing down the gas flow rate and effectively eliminating the noise generated by the gas.

[0076] When the patient exhales, the gas is blown in the opposite direction into the outlet component 11, the first airflow tube 13, and the second airflow tube 22. Through its own elastic expansion characteristics, it can store gas pressure to slow down the gas flow rate and thus eliminate the noise generated by the gas. At the same time, the gas exhaled by the patient is also transmitted to the third airflow tube 23 through the air source 2. Through the elastic expansion characteristics of the third airflow tube 23, it stores gas pressure to slow down the gas flow rate and thus eliminate the noise generated by the gas.

[0077] The ventilation therapy device provided by this utility model may also include a breathing mask, which may adopt various known structural forms.

[0078] Furthermore, in the ventilation therapy device of this utility model, the structures and components that are not described in detail can adopt various known structural forms.
