[0030] One embodiment of the present invention provides a ventilator, such as Figure 1 , Figure 3 and Figure 4 As shown, the ventilator includes a cavity structure 11, a positioning component 12, a high-frequency oscillation device 21 and a pipeline component 22, the high-frequency oscillation device 21 is located in the cavity structure 11, the input end of the pipeline component 22 penetrates into the cavity structure 11 and communicates with the high-frequency oscillation device 21, the high-frequency oscillation device 21 is used to deliver a high-frequency oscillation airflow through the pipeline component 22, the positioning component 12 is respectively connected to the high-frequency oscillation device 21 and the cavity structure 11, and the positioning component 12 is arranged around the high-frequency oscillation device 21.

[0031] The ventilator includes a housing 33 and a base 32, and the housing 33 is screwed to the base 32. An opening 111 for the high-frequency oscillation device 21 to enter and exit is provided at the bottom of the cavity structure 11, and a connecting plate 112 is provided at the opening 111, and the connecting plate 112 faces the outside of the cavity structure 11, and the connecting plate 112 is screwed to the base 32 to achieve the connection between the cavity structure 11 and the housing 33.

[0032] The high-frequency oscillation device 21 includes a shell, an actuator, a piston and a diaphragm. The actuator, the piston and the diaphragm are all accommodated in the shell. The diaphragm is arranged on the piston. The actuator drives the piston to perform linear reciprocating motion, so that the gas generates positive and negative pressure waves in the shell.

[0033] The positioning component 12 is an annular structure, a mounting hole is provided at the center of the positioning component 12, the high-frequency oscillation device 21 is inserted into the mounting hole, a first connecting hole is provided on the shell of the high-frequency oscillation device 21, a second connecting hole is provided on the positioning component 12, and a third connecting hole is provided on the cavity structure 11. Bolt fasteners pass through the first connecting hole, the second connecting hole and the third connecting hole in sequence to achieve the connection between the cavity structure 11, the positioning component 12 and the high-frequency oscillation device 21.

[0034] The pipeline assembly 22 includes a first pipeline 221, and a through-tube hole is provided on the cavity structure 11, and the first pipeline 221 passes through the through-tube hole and is connected to the high-frequency oscillation device 21. The ventilator includes a patient end, and the patient end is used to connect with the patient and deliver airflow to the patient. The other end of the first pipeline 221 is inserted into the patient end to achieve the delivery of high-frequency oscillating airflow. In one embodiment, a positioning sleeve is also provided in the through-tube hole, and the positioning sleeve is provided on the first pipeline 221. The inner wall of the positioning sleeve is in contact with the first pipeline 221, and the positioning sleeve is used to limit the displacement of the first pipeline 221 in the through-tube hole to prevent the first pipeline 221 from shaking and causing airflow disturbance.

[0035] The advantage of such a configuration is that, by arranging the high-frequency oscillation device 21 in the cavity structure 11, the input end of the pipeline component 22 passes through the cavity structure 11 and is connected to the high-frequency oscillation device 21, so that the high-frequency oscillation device 21 can deliver a high-frequency oscillation airflow through the pipeline component 22, for example, deliver a high-frequency oscillation airflow to the patient end, thereby realizing high-frequency ventilation of the ventilator. The positioning component 12 is respectively connected to the high-frequency oscillation device 21 and the cavity structure 11, so that the positioning component 12 can reduce the vibration amplitude of the high-frequency oscillation device 21. On the one hand, it can prevent the high-frequency oscillation device 21 from vibrating too much during operation and causing airflow disturbance, causing discomfort or injury to the patient. On the other hand, it reduces the noise generated during operation of the high-frequency oscillation device 21, so that the ventilator is quieter during operation. The positioning component 12 is arranged around the high-frequency oscillation device 21, so that the positioning component 12 can circumferentially position the high-frequency oscillation device 21, thereby avoiding uneven force on the high-frequency oscillation device 21 and tilting due to unilateral positioning, thereby increasing the operating stability of the high-frequency oscillation device 21.

[0036] like Figure 4 , Figure 5 As shown, the positioning assembly 12 includes a first limiting ring 121, a second limiting ring 122 and a buffer 123, the first limiting ring 121 is sleeved on the high-frequency oscillation device 21, the second limiting ring 122 is connected to the inner wall of the cavity structure 11, and the buffer 123 is located between the first limiting ring 121 and the second limiting ring 122 and abuts against the first limiting ring 121 and the second limiting ring 122 respectively.

[0037] The first limiting ring 121 is provided with a mounting hole, the mounting hole is arranged along the axial direction of the first limiting ring 121, the high-frequency oscillation device 21 is inserted into the mounting hole, the inner wall of the first limiting ring 121 is fitted with the outer wall of the high-frequency oscillation device 21, and the first limiting ring 121 is bolted and connected to the high-frequency oscillation device 21. The second limiting ring 122 is coaxially arranged with the first limiting ring 121, the second limiting ring 122 is sleeved on the first limiting ring 121, and the second limiting ring 122 is bolted and connected to the inner wall of the cavity structure 11; the buffer 123 can be any one of a spring, a rubber pad or a buffer cotton, the buffer 123 is screwed to the first limiting ring 121 and the second limiting ring 122 respectively, one end of the buffer 123 is fitted with the first limiting ring 121 and has an elastic force, and the other end of the buffer 123 is fitted with the second limiting ring 122 and has an elastic force. In another embodiment, a plane structure is provided on the outer wall of the second limiting ring 122, and the plane structure is fitted with the inner wall of the cavity structure 11 so that the second limiting ring 122 is in surface contact with the cavity structure 11. Thus, the contact area between the second limiting ring 122 and the cavity structure 11 is increased, thereby increasing the connection stability between the positioning assembly 12 and the cavity structure 11.

[0038] When the high-frequency oscillation device 21 generates radial vibration, the high-frequency oscillation device 21 drives the first limiting ring 121 to move in the radial direction. On the one hand, the buffer 123 can generate an elastic force in the opposite direction of the movement direction of the first limiting ring 121 to reduce the shaking amplitude of the high-frequency oscillation device 21; on the other hand, the buffer 123 can serve as a buffer zone between the high-frequency oscillation device 21 and the cavity structure 11 to slow down the vibration transmission between the high-frequency oscillation device 21 and the cavity structure 11; thereby making the operation of the high-frequency oscillation device 21 more stable.

[0039] like Figure 4 , Figure 5As shown, a limiting hole 1221 is provided on the second limiting ring 122 , and the limiting hole 1221 is arranged along the radial direction of the second limiting ring 122 . The first limiting ring 121 includes a limiting column 1222 , and the limiting column 1222 is penetrated in the limiting hole 1221 and is suitable for sliding in the limiting hole 1221 .

[0040] There are four limiting holes 1221, and the four limiting holes 1221 are arranged along the circumferential array of the second limiting ring 122; the limiting columns 1222 are arranged along the radial direction of the first limiting ring 121, and the number of the limiting columns 1222 corresponds to the number of the limiting holes 1221, and the limiting columns 1222 and the limiting holes 1221 are arranged coaxially. When the high-frequency oscillation device 21 generates radial vibration, the first limiting ring 121 follows the radial movement of the high-frequency oscillation device 21 along the second limiting ring 122, and the limiting column 1222 can slide in the limiting hole 1221 to prevent the first limiting ring 121 from driving the second limiting ring 122 to move, thereby weakening the vibration transmission between the high-frequency oscillation device 21 and the cavity structure 11; on the other hand, when the high-frequency oscillation device 21 generates axial vibration, the limiting hole 1221 can also limit the axial movement of the first limiting ring 122 through the limiting column 1222, so that the first limiting ring 121 can not only limit the displacement of the high-frequency oscillation device 21 in the radial direction, but also limit the displacement of the high-frequency oscillation device 21 in the axial direction (i.e., the Y-axis direction in the figure), thereby making the operation of the high-frequency oscillation device 21 more stable. Figure 4 , Figure 6 As shown, the ventilator further includes a buffer device 13 , which is installed in the cavity structure 11 , and the buffer device 13 is arranged to fit with one axial end of the first limiting ring 121 .

[0041] The buffer device 13 can be any one of a hydraulic buffer, a spring buffer or a rubber buffer. The buffer device 13 is fastened to the inner wall bolts of the cavity structure 11. The buffer device 13 fits with one axial end of the first limiting ring 121, and one end of the length direction of the first limiting ring 121 refers to one end of the linear reciprocating motion direction of the actuator of the high-frequency oscillation device 21 (i.e., the direction indicated by the Y-axis direction in the accompanying drawings). In one embodiment, there are four buffer devices 13, and the four buffer devices 13 are respectively arranged on both sides of the axial direction of the first limiting ring 121. When the high-frequency oscillation device 21 pushes the gas to generate positive and negative pressure waves, the high-frequency oscillation device 21 is prone to swing in the direction of pushing the gas to generate positive and negative pressure waves (i.e., the Y-axis direction in the figure), and is installed in the cavity structure 11 through the buffer device 13. The buffer device 13 is arranged to fit together with one axial end of the first limiting ring 121. The buffer device 13 can buffer the high-frequency oscillation device 21 through the first limiting ring 121, thereby reducing the vibration amplitude of the high-frequency oscillation device 21 in the Y-axis direction to avoid airflow disturbance.

[0042] like Figure 6 As shown, the buffer device 13 includes a limiting member 131 and an elastic member 132 . The limiting member 131 is connected to the inner wall of the cavity structure 11 , and the elastic member 132 is positioned and matched with the limiting member 131 and at least partially fits with the first limiting ring 121 .

[0043] The stopper 131 is a semi-enclosed structure, and the stopper 131 is integrally connected to the inner wall of the cavity structure 11. The elastic member 132 is a columnar structure, and the elastic member 132 is embedded in the stopper 131. The elastic member 132 is at least partially exposed from the stopper 131 so that the elastic member 132 fits the first stopper ring 121. The elastic member 132 can be made of elastic materials such as polyurethane, rubber or silicone.

[0044] The advantage of such a configuration is that, by positioning and cooperating with the limiting member 131 and the elastic member 132, the limiting member 131 can stop the elastic member 132. On the one hand, it can prevent the elastic member 132 from shifting under the shaking of the first limiting ring 121 and thus eliminating the buffering effect. On the other hand, the elastic member 132 can be tightly attached to the first limiting ring 121 so that there is a certain elastic force between the elastic member 132 and the first limiting ring 121, thereby allowing the elastic member 132 to stabilize the first limiting ring 121 in the length direction.

[0045] like Figures 2 to 4As shown, the ventilator also includes an airflow regulating device 23, the output end of the pipeline assembly 22 is connected to the airflow regulating device 23, the airflow regulating device 23 is suitable for being connected to the patient end, and the airflow regulating device 23 is used to regulate the airflow output from the pipeline assembly 22.

[0046] The airflow regulating device 23 is a chamber structure, and an air inlet is provided on the upper end plate of the airflow regulating device 23, and the air inlet is connected to the output end of the pipeline assembly 22. The airflow regulating device 23 is also provided with an air outlet 233, and a filter 27 is provided at the air outlet 233. The filter 27 is used to filter the airflow flowing out of the air outlet 233 to prevent the impurities in the airflow from causing secondary infection of the patient. During the operation of the high-frequency oscillation device 21, the high-frequency oscillation device 21 delivers the high-frequency oscillating airflow to the airflow regulating device 23 through the pipeline assembly 22, and then the airflow regulating device 23 delivers the high-frequency oscillating airflow to the patient end.

[0047] The advantage of such a configuration is that the output end of the pipe assembly 22 is connected to the airflow regulating device 23, and the airflow regulating device 23 is connected to the patient end, so that the airflow output by the pipe assembly 22 can first pass through the airflow regulating device 23 and then enter the patient end. The airflow regulating device 23 buffers and regulates the airflow output by the pipe assembly 22 so that the airflow has a stable frequency, flow rate and pressure, thereby avoiding damage to the patient's lungs due to unstable airflow oscillation frequency.

[0048] like Figure 3 As shown, the pipeline assembly 22 includes a first pipeline 221 and a second pipeline 222, the first pipeline 221 is connected to the airflow regulating device 23 and the high-frequency oscillation device 21 respectively, one end of the second pipeline 222 is connected to the airflow regulating device 23, and the other end of the second pipeline 222 is suitable for connecting to the air source assembly 24.

[0049] The gas source component 24 can be any one of a turbine fan, an axial flow fan or a pure oxygen compressed gas source. The gas flow regulating device 23 is provided with a first gas inlet and a second gas inlet. One end of the second pipeline 222 is connected to the output end of the gas source component 24, and the other end of the second pipeline 222 is inserted into the first gas inlet. The gas source component 24 delivers gas into the gas flow regulating device 23 through the second pipeline 222. One end of the first pipeline 221 is inserted into the second gas inlet of the gas flow regulating device 23, and the other end of the first pipeline 221 is inserted at the input end of the high-frequency oscillation device 21. During the operation of the high-frequency oscillation device 21, the gas source component 24 delivers gas into the gas flow regulating device 23, and the high-frequency oscillation device 21 reciprocates and pumps the gas in the gas flow regulating device 23, so that the gas in the gas flow regulating device 23 forms an oscillating gas flow. In one embodiment, the first pipeline 221 is an arc-shaped pipeline, and the arc-shaped pipeline can buffer the airflow output by the high-frequency oscillation device 21 so that the airflow has a stable pressure and flow rate, and the airflow output by the high-frequency oscillation device 21 is more stable. In another embodiment, the airflow regulating device 23 is also provided with a high-frequency switch valve 232, and the high-frequency switch valve 232 is used to control the opening or closing of the second air inlet, so that the high-frequency airflow can be opened or closed. In some embodiments, the airflow regulating device 23 is also provided with a third air inlet, and a safety valve 231 is also provided at the third air inlet. The safety valve 231 is used to control the opening or closing of the third air inlet. When other components of the airflow regulating device 23 fail, such as when a power outage causes other airflows to be unable to enter, the safety valve 231 can be opened to connect the patient's breathing circuit with the atmosphere, etc., to play a role in safety protection.

[0050] The advantage of such a configuration is that the second pipeline 222 is respectively connected with the gas source component 24 and the airflow regulating device 23, so that the gas source component 24 can transport gas to the airflow regulating device 23 through the second pipeline 222; the first pipeline 221 is respectively connected with the airflow regulating device 23 and the high-frequency oscillation device 21, so that the high-frequency oscillation device 21 can realize the input and output of airflow through the first pipeline 221, avoiding the need to set up an additional pipeline to transport airflow to the high-frequency oscillation device 21, so that the pipeline can be integrated into the airflow regulating device 23, thereby reducing the size of the ventilator and increasing the portability of the ventilator.

[0051] like Figure 2 As shown, the ventilator further includes a pipeline fixing member 31 , which is connected to the outer side wall of the cavity structure 11 , and is used to fix the first pipeline 221 and separate the first pipeline 221 from the second pipeline 222 .

[0052] The pipeline fixing part 31 is bolted and connected to the outer wall of the cavity structure 11. The pipeline fixing part 31 is a U-shaped structure. The pipeline fixing part 31 completely covers the area where the second pipeline 222 is located. The pipeline fixing part 31 includes a side plate, which is arranged between the first pipeline 221 and the second pipeline 222. The side plate separates the area where the first pipeline 221 and the second pipeline 222 are located. Thus, the pipeline fixing part 31 is connected to the outer wall of the cavity structure 11, so that the pipeline fixing part 31 can fix the second pipeline 222 on the cavity structure 11. Since the high-frequency oscillation device 21 will drive the first pipeline 221 to shake when it is running, the first pipeline 221 and the second pipeline 222 are separated by the pipeline fixing part 31, which can avoid the first pipeline 221 and the second pipeline 222 from colliding and affecting the airflow stability.

[0053] like Figures 2 to 3 As shown, the ventilator further includes a constant frequency device 25 , which is connected to the pipeline assembly 22 , and is used to deliver a constant frequency airflow to the patient end through the pipeline assembly 22 .

[0054] The constant frequency device 25 can be any one of a mechanical constant frequency ventilation device or a constant frequency ventilator. The pipeline assembly 22 also includes a third pipeline 223, one end of the third pipeline 223 is connected to the air source assembly 24, and the other end of the third pipeline 223 is connected to the constant frequency device 25. The air source assembly 24 is used to deliver airflow to the constant frequency device 25 through the third pipeline 223. The airflow regulating device 23 is also provided with a fourth air inlet, and the constant frequency device 25 is connected to the fourth air inlet through a pipeline. A flow regulating valve 234 is also provided at the fourth air inlet, and the flow regulating valve 234 is used to adjust the airflow flow delivered by the constant frequency ventilation device to the airflow regulating device 23. During the operation of the ventilator, when it is necessary to deliver a normal frequency airflow to the patient, the flow regulating valve 234 is opened so that the normal frequency ventilation device can deliver a normal frequency airflow to the airflow regulating device 23, and the airflow regulating device 23 delivers the normal frequency airflow to the patient end to achieve the delivery of the normal frequency airflow. When it is necessary to deliver a high frequency airflow to the patient, the flow regulating valve 234 is closed, and the high frequency switch valve 232 is opened, thereby achieving the delivery of the high frequency airflow. In one embodiment, the ventilator also includes an atomizing device 26, which is connected to the pipeline assembly 22, and the atomizing device 26 is bolted to the cavity structure 11. The atomizing device 26 is used to atomize the medicine and deliver the atomized liquid medicine to the patient end through the pipeline assembly 22.

[0055] The advantage of such a configuration is that the constant frequency device 25 is connected to the pipeline assembly 22, so that the constant frequency device 25 can deliver a constant frequency airflow to the patient end through the pipeline assembly 22, so that the ventilator has both high-frequency ventilation and constant frequency ventilation functions, thereby increasing the scope of application of the ventilator.

[0056] like Figure 1 , Figure 7 and Figure 8 As shown, the ventilator further includes a base 32 and a shell 33 , wherein the base 32 and the shell 33 are detachably connected, and the base 32 and the shell 33 together form an installation space for the cavity structure 11 and the pipeline assembly 22 .

[0057] The base 32 is screwed to the housing 33. The base 32 includes a first side plate 321, a second side plate 322, a third side plate 323, a fourth side plate 324 and a bottom plate 325. The first side plate 321, the second side plate 322 and the bottom plate 325 are integrally connected. The first side plate 321 is provided with a first through hole. The gas delivery end of the airflow regulating device 23 is inserted into the first through hole. The first side plate 321 is also provided with a second through hole.
