[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0026] It has been found by the inventors of the present application that, for the convenience of medical operations, in modern clinical medicine, as an effective means to artificially replace the function of autonomous ventilation, ventilators have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgeries, respiratory support treatment, and first aid resuscitation, and occupy a very important position in the field of modern medicine. However, existing ventilators are usually a whole, and the installation and disassembly processes are relatively cumbersome. To solve the above problems, the following embodiments are proposed in the present application.

[0027] The following is an exemplary description of the ventilator in the embodiments of the present application.

[0028] The ventilator 1 is a device that can replace, control, or change a person's normal physiological respiration, increase pulmonary ventilation volume, improve respiratory function, reduce the consumption of respiratory work, and save the heart's reserve capacity.

[0029] In some embodiments, as Figure 1 shown, the ventilator 1 includes a humidifying device 10 and a turbine device 20. The humidifying device 10 is connected to the mixed gas outlet 2213 of the turbine device 20 to warm and humidify the mixed gas coming out of the mixed gas outlet 2213. The turbine device 20 is used to mix oxygen and air to form a mixed gas and output it to form a stable gas source.

[0030] Optionally, the ventilator 1 may further include a controller 30, and the controller 30 is used to control the humidifying device 10 and the turbine device 20 to adjust the warming and humidifying conditions of the humidifying device 10, the mixing speed of the turbine device 20, and the output speed of the mixed gas.

[0031] In some embodiments, as Figures 2 to 3 shown, the turbine device 20 may include a base 210, a turbine fan assembly 220, a filter element 230, and a noise reduction element 240. Among them, the turbine fan assembly 220 can be used to mix oxygen and air to form a mixed gas and can output it to the outside to form a stable gas source. The filter element 230 can be used to filter impurities, moisture, etc. in the air so that the air entering the turbine fan assembly 220 is relatively clean. The noise reduction element 240 can be used to reduce the noise of the mixed gas outlet of the turbine fan assembly 220 to reduce the noise generated by the turbine device 20.

[0032] Optionally, as Figures 2 to 3As shown, the machine base 210 may be provided with a first placement cavity 211, a second placement cavity 212, and a third placement cavity 213. The turbine fan assembly 220, the filter element 230, and the noise reduction element 240 may be respectively installed in the first placement cavity 211, the second placement cavity 212, and the third placement cavity 213. Therefore, the turbine device 20 described in the present application can modularly distinguish each component by dividing the space in the machine base 210, so that the turbine fan assembly 220, the filter element 230, and the noise reduction element 240 can be independently installed in different installation spaces of the machine base 210, thereby simplifying the structure of the turbine device 20 and facilitating the installation and disassembly of the turbine device 20. Moreover, when one of the turbine fan assembly 220, the filter element 230, and the noise reduction element 240 in the turbine device 20 is damaged, only the corresponding module can be replaced during the repair process, without having to disassemble the whole or without having to disassemble other irrelevant mechanical components, thereby improving the repair efficiency of the turbine device 20.

[0033] In some embodiments, the turbine fan assembly 220, the filter element 230, and the noise reduction element 240 may be installed on the machine base 210 by means of pin and screw fixation. Of course, in other embodiments, other methods such as snap-fit and adhesive tape bonding may also be used to install the turbine fan assembly 220, the filter element 230, and the noise reduction element 240 on the machine base 210.

[0034] In some embodiments, as Figure 4 shown, the turbine fan assembly 220 may include a fan 222 and a housing 221. The housing 221 is detachably fixed in the first placement cavity 211, and the fan 222 is arranged in the housing 221. An oxygen inlet 2201, an air inlet 2202, and a mixed gas outlet 2213 are formed on the housing 221. A gas mixing cavity 2203 is provided in the housing 221. The fan includes a fan inlet 2221 and a fan outlet 2222. The oxygen inlet 2201, the air inlet 2202, and the fan inlet 2221 communicate with the gas mixing cavity 2203, and the fan outlet 2222 communicates with the mixed gas outlet 2213. The fan 222 has the function of mixing air and oxygen and has the function of continuously and stably outputting air flow.

[0035] Optionally, an air passage 2211 and an oxygen passage 2212 are formed on the housing 221. One end of the air passage 2211 communicates with the air inlet 2202, and the other end communicates with the gas mixing cavity 2203. One end of the oxygen passage 2212 communicates with the oxygen inlet 2201, and the other end communicates with the gas mixing cavity 2203. Optionally, a receiving cavity 2214 may also be provided in the housing 221, and the fan 222 may be arranged in the receiving cavity 2214.

[0036] In some embodiments, the blower 222 may include a housing (not shown in the figure), an impeller (not shown in the figure), and a motor (not shown in the figure). The blower air inlet 2221 and the blower air outlet 2222 are provided on the housing, and the blower air inlet 2221 and the blower air outlet 2222 communicate with the interior of the housing. The impeller and the motor are also installed inside the housing. Among them, the motor may be electrically connected to the controller 30, and the impeller may also be connected to the motor. Under the control of the controller 30, the motor can drive the impeller to rotate inside the housing.

[0037] Specifically, air enters the air passage 2211 from the air inlet 2202 and further enters the gas mixing chamber 2203. Oxygen enters the oxygen passage 2212 from the oxygen inlet 2201 and further enters the gas mixing chamber 2203. The air and oxygen are preliminarily mixed in the gas mixing chamber 2203. Then, the air and oxygen in the gas mixing chamber 2203 enter the interior of the housing of the blower 222 through the blower air inlet 2221. The impeller rotates at a high speed driven by the motor to further mix the air and oxygen evenly to form a mixed gas. The mixed gas further passes through the blower air outlet 2222 in sequence to leave the blower, and further is output to the noise reduction member 240 through the mixed gas outlet 2213.

[0038] In some embodiments, such as Figure 3 and Figure 4 As shown, the housing 221 may include an upper cover 2215 and a lower cover 2216. The upper cover 2215 and the lower cover 2216 are covered with each other to form an accommodation chamber 2214, an air passage 2211, an oxygen passage 2212, and a gas mixing chamber 2203. Such a setting can facilitate the assembly of the housing 221 and simplify the structure inside the housing 221.

[0039] Among them, the upper cover 2215 and the lower cover 2216 can be hermetically arranged, so that air leakage and gas leakage are not likely to occur in the accommodation chamber 2214, the air passage 2211, the oxygen passage 2212, and the gas mixing chamber 2203, so as to ensure the airtightness of the turbine device 20.

[0040] Optionally, as Figure 4 and Figure 5 As shown, the turbo blower assembly 220 further includes an oxygen inlet pipe 223 fixed to the housing 221. One end of the oxygen inlet pipe 223 is hermetically connected to the oxygen inlet 2201, and the other end extends out of the surface of the housing 221. The other end of the oxygen inlet pipe 223 can be connected to an oxygen supply device. The oxygen supply device can supply oxygen to the oxygen passage 2212 through the oxygen inlet pipe 223 to supply oxygen to the blower 222.

[0041] With the above settings, the air passage 2211, the oxygen passage 2212, the gas mixing chamber 2203, and the blower 222 are all installed in the housing 221, so that the components for pressurizing and mixing air and oxygen in the turbine device 20 are concentrated in the housing 221. This can also miniaturize the core module of the turbine device 20, simplify the structure of the turbine device 20, and make the turbine blower assembly 220 form a relatively independent module, facilitating the installation and disassembly of the turbine blower assembly 220. When a certain component in the turbine blower assembly 220 is damaged, only the turbine blower assembly 220 needs to be replaced for repair, thereby improving the repair efficiency of the turbine device 20.

[0042] In some embodiments, as Figure 6 shown, the filter element 230 may include a housing 231. The housing 231 is detachably fixed to the second placement cavity 212, and a filter passage 2311 communicating with the outside may be provided in the housing 231. The filter passage 2311 may communicate with the air inlet 2202.

[0043] Optionally, the filter element 230 may include a variety of filter media sheets 232. Among them, the filter media sheets 232 can be made of materials such as non-woven fabric, nylon mesh, fiber filter paper, etc., for filtering impurities, dust, water vapor, etc. in the air. The filter media sheets 232 may be disposed in the filter passage 2311. When the blower 222 sucks air into the air passage 2211, the outside air enters the air passage 2211 through the filter passage 2311 of the filter element 230. Therefore, the air can be filtered and purified before entering the turbine blower assembly 220, thereby improving the safety of the turbine blower assembly 220.

[0044] Moreover, by arranging a variety of filter media sheets 232 and other filter elements in the housing 231, the filter element 230 can be made independent of the machine base 210, so it is convenient for the installation and disassembly of the filter element 230 and also convenient for the maintenance of the filter element 230.

[0045] In some embodiments, as Figure 6 shown, the second placement cavity 212 may communicate with the filter passage 2311. The turbine device 20 includes a negative pressure sensor 250. The negative pressure sensor 250 is disposed on the machine base 210 and extends into the second placement cavity 212 for detecting the air pressure in the second placement cavity 212 after passing through the filter passage 2311.

[0046] Optionally, as Figure 5 and Figure 6As shown, the second placement cavity 212 may include a first sub-cavity 2121 and a second sub-cavity 2122. The base 210 may include a partition plate 214 disposed between the first sub-cavity 2121 and the second sub-cavity 2122. The partition plate 214 may be provided with a through hole 2141 communicating the first sub-cavity 2121 and the second sub-cavity 2122. The filter element 230 may be disposed in the first sub-cavity 2121. The second sub-cavity 2122 communicates with the air inlet 2202, and the negative pressure sensor 250 extends into the second sub-cavity 2122. The filter channel 2311 communicates with the second sub-cavity 2122 through the through hole 2141.

[0047] Wherein, the external air can pass through the filter channel 2311 of the filter element 230 and enter the second sub-cavity 2122 through the through hole 2141, and the air pressure condition is detected by the negative pressure sensor 250 in the second sub-cavity 2122, and then enters the turbine fan assembly 220 through the inlet of the air inlet 2202.

[0048] After the filter element 230 is used for a period of time, the filter media sheet 232 of the filter element 230 will be covered with dust particles or other impurities. Therefore, the filter channel 2311 of the filter element 230 will be blocked, and air cannot pass through the filter element 230 and enter the second sub-cavity 2122, nor can it enter the inside of the turbine fan assembly 220. If the fan 222 is turned on at this time to start extracting the air in the air passage 2211, a negative pressure situation will occur in the second sub-cavity 2122. Therefore, a negative pressure sensor 250 is provided behind the filter channel 2311 of the filter element 230, which can timely detect the abnormal air pressure situation, and then can remind the user to replace the filter element 230, thereby improving the safety of the turbine device 20.

[0049] In some embodiments, such as Figure 7 and Figure 8 As shown, the noise reduction member 240 may include a box body 241. The box body 241 is detachably fixed to the third placement cavity 213. A noise reduction channel 2411 may be provided in the box body 241. The noise reduction channel 2411 may be connected to the mixed gas outlet 2213. Optionally, the noise reduction member 240 further includes a sound absorption layer 242. The sound absorption layer 242 is disposed in the noise reduction channel 2411 and fills the noise reduction channel 2411.

[0050] In some embodiments, the sound absorption layer 242 may be sound absorption cotton, foam plastic, sound absorption board, etc. While allowing the mixed gas to pass through, the sound absorption layer 242 reduces noise.

[0051] Optionally, the noise reduction channel 2411 may be provided with a second inlet 2412 and a second outlet 2413. The noise reduction channel 2411 may be connected to the mixed gas outlet 2213 through the second inlet 2412, and the second outlet 2413 is used for connecting to the gas pipeline of the external ventilator 1. The turbine fan assembly 220 mixes air and oxygen to form a mixed gas, and sends the mixed gas through the fan outlet 2222 and the mixed gas outlet 2213. The mixed gas enters the noise reduction channel 2411 through the mixed gas outlet 2213 and the second inlet 2412, and is output to the gas pipeline of the ventilator 1 after being noise-reduced by the noise reduction member 240.

[0052] In some embodiments, as Figure 8 shown, the housing 241 of the noise reduction member 240 may include an upper housing 2414 and a lower housing 2415. The upper housing 2414 and the lower housing 2415 are covered with each other to form the noise reduction channel 2411, and the sound absorption layer 242 is disposed between the upper housing 2414 and the lower housing 2415. The noise reduction member 240 may also be provided with a layer of sealing ring 243 between the upper housing 2414 and the lower housing 2415, so that the upper housing 2414 and the lower housing 2415 can be hermetically connected, thereby further ensuring the sealing performance of the noise reduction channel 2411. Optionally, a sealing member (not shown in the figure) may also be provided between the second inlet 2412 and the mixed gas outlet 2213 to achieve a sealed connection, so as to ensure that the mixed gas is not easily leaked during the process of being output to the noise reduction channel 2411.

[0053] By centrally disposing the sound absorption layer 242 in the housing 241, the components for realizing the noise reduction function in the turbine device 20 can be disposed in the housing 241, which is convenient for the installation and disassembly of the noise reduction member 240. And when a certain component of the noise reduction member 240 is damaged, the noise reduction member 240 can be separately disassembled from the machine base 210 for repair and detection without affecting other components in the turbine device 20.

[0054] Moreover, the arrangement of the turbine device 20 in the present application can not only achieve modular setting, the turbine fan assembly 220, the filter member 230 and the noise reduction member 240 can be independently installed in different installation spaces of the machine base 210, and then separated into different modules, but also can achieve the smooth flow of air. The air can enter the turbine fan assembly 220 through the filter member 230 and then flow to the noise reduction member 240. Therefore, the arrangement of the turbine device 20 in the present application not only reduces the difficulty of installation and disassembly and improves the maintenance efficiency, but also ensures the stability and feasibility of the ventilator 1.

[0055] In some embodiments, as Figure 3 shown, the machine base 210 may also be provided with a first heat dissipation window 215 communicating with the outside, and the first heat dissipation window 215 may communicate with the first placement cavity 211. AsFigure 4 As shown, the housing 221 may also be provided with a heat dissipation air channel 2217. The heat dissipation air channel 2217 may be provided with a heat dissipation air inlet 2218 and a heat dissipation air outlet 2219. The heat dissipation air inlet 2218 may communicate with the first heat dissipation window 215, and the heat dissipation air outlet 2219 is used to discharge the heat dissipation air. The heat dissipation air channel 2217 is spaced apart from and not in communication with the air channel 2211, the oxygen channel 2212, the gas mixing chamber 2203, and the mixed gas outlet 2213. Optionally, the accommodation chamber 2214 communicates with the heat dissipation air channel 2217.

[0056] Specifically, the heat dissipation air channel 2217 is not in communication with the interior of the blower 222. The heat dissipation air enters the heat dissipation air channel 2217 through the first heat dissipation window 215 and the heat dissipation air inlet 2218 of the housing 221, and further enters the accommodation chamber 2214 to dissipate heat from the surface of the blower 222 in the accommodation chamber 2214, and then is discharged through the heat dissipation air outlet 2219. Also, the heat dissipation air channel 2217 is not in communication with the blower air inlet 2221, and the heat dissipation air will not enter the interior of the blower 222 through the blower air inlet 2221 after entering the heat dissipation air channel 2217 and then entering the accommodation chamber 2214.

[0057] The provision of the heat dissipation air channel 2217 can dissipate heat from the surface of the blower 222 during the use of the turbine device 20, thereby minimizing the situation where the blower 222 is damaged due to overheating, and improving the safety and stability of the blower 222. The provision that the heat dissipation air channel 2217 is spaced apart from and not in communication with the air channel 2211, the oxygen channel 2212, the gas mixing chamber 2203, and the mixed gas outlet 2213 can prevent the heat dissipation air from easily affecting the mixed gas, so as to ensure the cleanliness of the mixed gas output by the turbine device 20.

[0058] In some embodiments, as Figure 3 shown, the turbine device 20 may further include a first heat dissipation fan 260, and the first heat dissipation fan 260 is detachably disposed in the first heat dissipation window 215. The first heat dissipation fan 260 is used to introduce the heat dissipation air from the outside into the heat dissipation air channel 2217. The provision of installing the first heat dissipation fan 260 in the first heat dissipation window 215 can facilitate the introduction of the heat dissipation air, so as to facilitate the heat dissipation of the blower 222.

[0059] In some embodiments, as Figure 8 shown, the noise reduction member 240 may also be provided with an exhaust air channel 244, and the exhaust air channel 244 is spaced apart from and not in communication with the noise reduction channel 2411. As Figure 7 and Figure 8As shown, the exhaust air passage 244 may be provided with a first access port 2441 and a first exhaust port 2442. The exhaust air passage 244 is connected to the heat dissipation air outlet 2219 through the first access port 2441, and the first exhaust port 2442 communicates with the outside for discharging the heat dissipation air. Setting the exhaust air passage 244 and the noise reduction passage 2411 to be spaced apart from each other and not communicating can prevent the heat dissipation air from easily contaminating the mixed gas in the noise reduction passage 2411, thereby ensuring the relatively clean mixed gas output by the ventilator 1.

[0060] In some embodiments, as Figure 2 , Figure 3 and Figure 7 shown, the machine base 210 is provided with a second heat dissipation window 216 communicating with the first placement cavity 211, and there is a spaced space 217 between the second heat dissipation window 216 and the machine shell 221. Among them, the second heat dissipation window 216 is used for the heat dissipation air to enter the first placement cavity 211 and flow out through the gap between the machine shell 221 and the machine base 210.

[0061] Optionally, the turbine device may include a second heat dissipation fan (not shown in the figure), and the second heat dissipation fan is arranged in the spaced space 217. Specifically, the second heat dissipation fan can introduce the heat dissipation air into the first placement cavity 211 through the second heat dissipation window 216 to dissipate heat from the machine shell 221, and the heat dissipation air can flow out through the gap between the machine shell 221 and the machine base 210, so as to strengthen the heat dissipation of the turbine fan assembly 220 and prevent the turbine device 20 from being damaged due to overheating as much as possible.

[0062] In some other embodiments, a fan may not be provided in the spaced space 217, so that there is a certain interval between the second heat dissipation window 216 and the machine shell 221, and the heat dissipation air can be blown into the second heat dissipation window 216 by an external fan to enter the first placement cavity 211 and circulate in the first placement cavity 211.

[0063] In summary, in the turbine device 20 of the present application, the machine base 210 is provided with a first placement cavity 211, a second placement cavity 212 and a third placement cavity 213, and the turbine fan assembly 220 can be detachably installed in the first placement cavity 211, the filter element 230 can be detachably installed in the second placement cavity 212, and the noise reduction element 240 can be detachably installed in the third placement cavity 213.
