Description

Technical Field

[0001] The present invention relates to the technical field of respiratory assistance, and in particular to an auxiliary respiratory device for critically ill patients. Background Art

[0002] Critically ill patients are those whose condition develops suddenly, is critical, and changes rapidly. A single misstep can lead to irreparable consequences. Therefore, doctors must be able to make accurate assessments and determine treatment options quickly. Critically ill patients often experience breathing difficulties, so a ventilator is typically used to provide oxygen to normalize blood oxygen levels.

[0003] However, the oxygen moisture content and temperature in most ventilators are low, and critically ill patients have poor adaptability, making it difficult for them to adapt, which slows down their recovery speed and can even cause physical damage to them. Summary of the Invention

[0004] In view of the above problems existing in the prior art, the technical problem to be solved by the present invention is that the moisture content and temperature of oxygen in most ventilators are low, and critically ill patients have poor self-adaptability, making it difficult for critically ill patients to adapt themselves.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: an auxiliary breathing device for critically ill patients, comprising:

[0006] water storage tanks;

[0007] an air intake mechanism for delivering oxygen into the water storage tank;

[0008] An air delivery mechanism, for discharging the gas in the water storage tank, wherein the air delivery mechanism and the air intake mechanism are coaxially arranged;

[0009] A stirring mechanism, wherein one end of the stirring mechanism is rotatably mounted on the gas delivery mechanism, and the other end of the stirring mechanism is rotatably mounted on the gas intake mechanism, and the gas delivered by the gas intake mechanism drives the stirring mechanism to rotate; and

[0010] A heater is used to heat the liquid in the water storage tank.

[0011] In the present invention, one end of the respirator is connected to the air intake mechanism, and one end of the oxygen mask is connected to the air delivery mechanism; the water tank is filled with water, and the water surface covers the air intake mechanism but cannot cover the air delivery mechanism; then the heater is turned on, and the heater heats the water in the water tank to generate water vapor, and then the respirator is activated, and the respirator delivers oxygen into the water tank through the air intake mechanism, and the oxygen drives the stirring mechanism to rotate and enters the water in the water tank at the same time, and the heated water heats the oxygen. At the same time, the stirring mechanism stirs the water vapor and oxygen, so that the water vapor and oxygen are mixed, thereby humidifying the oxygen; finally, the heated and humidified oxygen is delivered to the oxygen mask through the air delivery mechanism, so that critically ill patients can feel more comfortable when using the respirator.

[0012] Preferably, the air intake mechanism comprises an air intake pipe and a one-way assembly; one end of the air intake pipe extends into the water tank and is fixedly connected to the water tank; the air intake pipe is coaxially arranged with the air delivery mechanism, and the stirring mechanism is rotatably mounted on the air intake pipe at one end away from the air delivery mechanism; a plurality of drive ports are provided on the side of the air intake pipe, and the air intake pipe is connected to the water tank through the drive ports; the plurality of drive ports are arranged in a circular array about the axis of the air intake pipe, and the drive ports are inclined in the radial direction of the air intake pipe, with the openings of the drive ports facing the stirring mechanism; the one-way assembly controls the one-way air intake of the air intake pipe into the water tank. After oxygen enters the air intake pipe, it passes through the one-way assembly, which prevents water in the water tank from entering the air intake pipe, and then the oxygen is discharged through the drive ports; when the oxygen is discharged through the inclined drive ports, it exerts a certain component of force on the stirring mechanism in a tangential direction, so that the oxygen can drive the stirring mechanism to rotate through the inclined drive ports, and simultaneously discharge the oxygen into the water tank.

[0013] Preferably, the one-way assembly is installed in the air intake pipe and includes a spring, a sliding plug, and a limiting ring. One end of the spring abuts against the end of the air intake pipe located in the water storage tank, and the other end of the spring is fixedly connected to the sliding plug. The sliding plug slides in engagement with the air intake pipe. The limiting ring is coaxially fixedly connected to the air intake pipe, with the drive port located between the limiting ring and the spring. This prevents water in the water storage tank from entering the air intake pipe.

[0014] Preferably, a first connector is installed at one end of the air inlet pipe located outside the water storage tank, and is detachably connected to a pipeline of the ventilator via the first connector.

[0015] Preferably, the gas delivery mechanism includes a gas delivery pipe and a second connector; one end of the gas delivery pipe extends into the water storage tank and is fixedly connected to the water storage tank; the gas delivery pipe is coaxially arranged with the air intake mechanism; the end of the stirring mechanism remote from the air intake mechanism is rotatably mounted on the gas delivery pipe; the second connector is mounted on the other end of the gas delivery pipe, and is detachably connected to the oxygen mask via the second connector.

[0016] Preferably, the stirring mechanism includes stirring blades and a connecting ring; multiple stirring blades are arranged in a circular array along the axis of the air intake mechanism, and both ends of each stirring blade are fixedly mounted on the connecting ring; one of the connecting rings is rotatably mounted on the air intake mechanism, and the other connecting ring is rotatably mounted on the air delivery mechanism.

[0017] The gas delivered by the air intake mechanism applies a thrust to the stirring blades, causing the multiple stirring blades to rotate around the air intake mechanism through the connecting ring, thereby stirring the water and gas in the water storage tank; by stirring the water, the water in the water storage tank can be heated more evenly; by stirring the gas, the water vapor and oxygen can be mixed more evenly.

[0018] Preferably, the stirring blade has an arc-shaped cross-section along the axis of the air intake mechanism and is curved in the direction opposite to the rotation of the stirring blade. This allows oxygen to contact the curved inner side of the stirring blade when it is ejected from the air intake mechanism, thereby increasing the resistance of the stirring blade to oxygen and thereby increasing the utilization rate of the oxygen thrust. At the same time, the curved outer side of the stirring blade pushes the water flow, thereby reducing the resistance of the water flow to the stirring blade.

[0019] Preferably, the air conveying mechanism further comprises a fixing mechanism for fixing the water tank. The fixing mechanism fixes the water tank, thereby effectively preventing the water tank from shaking, which would cause the water in the water tank to enter the air conveying mechanism.

[0020] Preferably, the fixing mechanism includes a rotating shaft, a connecting plate, and a fixing portion; rotating shafts are respectively provided on opposite sides of the water tank in the radial direction, and the rotating shafts are located at one end of the water tank close to the gas transmission mechanism, and the rotating shafts are fixedly connected to the water tank; each rotating shaft is mounted on the fixing portion via a connecting plate, the rotating shaft and the connecting plate are arranged perpendicularly, the rotating shaft is rotatably mounted on one end of the connecting plate, and the other end of the connecting plate is fixedly connected to the fixing portion; the fixing portion can be detachably fixed to other objects. When the fixing portion is fixed to other objects, under the action of gravity, the water tank drives the rotating shaft to rotate on the connecting plate, causing the bottom of the water tank to fall vertically, thereby effectively preventing the water tank from shaking, which causes the water in the water tank to enter the gas transmission mechanism.

[0021] Compared with the prior art, the present invention has at least the following advantages:

[0022] 1. Humidify and heat the oxygen. The heated and humidified oxygen is transported to the oxygen mask through the air transmission mechanism, making it more comfortable for critically ill patients to use the ventilator. In the present invention, one end of the ventilator is connected to the air intake mechanism, and one end of the oxygen mask is connected to the air transmission mechanism; the water tank is filled with water, and the water surface covers the air intake mechanism but cannot cover the air transmission mechanism; then the heater is turned on, and the heater heats the water in the water tank to generate water vapor. Then the ventilator is activated and transports oxygen into the water tank through the air intake mechanism. The oxygen drives the stirring mechanism to rotate and enters the water in the water tank at the same time. The heated water heats the oxygen. At the same time, the stirring mechanism stirs the water vapor and oxygen, so that the water vapor and oxygen are mixed, thereby humidifying the oxygen; finally, the heated and humidified oxygen is transported to the oxygen mask through the air transmission mechanism, making it more comfortable for critically ill patients to use the ventilator.

[0023] 2. The gas delivered by the air intake mechanism applies a thrust to the stirring blades, causing the multiple stirring blades to rotate around the air intake mechanism through the connecting ring, thereby stirring the water and gas in the water storage tank; by stirring the water, the water in the water storage tank can be heated more evenly; by stirring the gas, the water vapor and oxygen can be mixed more evenly.

[0036] See also Figure 1-Figure 2 The present invention provides an embodiment of an auxiliary breathing device for critically ill patients, comprising: a water storage tank 1, an air intake mechanism 2, an air delivery mechanism 3, a stirring mechanism 4 and a heater 5; the water in the water storage tank 1 may be distilled water, and the air intake mechanism 2 delivers oxygen into the water storage tank 1; the air delivery mechanism 3 discharges the gas in the water storage tank 1, and the air delivery mechanism 3 and the air intake mechanism 2 are coaxially arranged; one end of the stirring mechanism 4 is rotatably mounted on the air delivery mechanism 3, and the other end of the stirring mechanism 4 is rotatably mounted on the air intake mechanism 2, and the gas delivered by the air intake mechanism 2 drives the stirring mechanism 4 to rotate; the heater 5 heats the liquid in the water storage tank 1.

[0037] During the specific implementation, one end of the respirator is connected to the air intake mechanism 2, and one end of the oxygen mask is connected to the air delivery mechanism 3; the water tank 1 is filled with water, and the water surface is above the air intake mechanism 2 and cannot be above the air delivery mechanism 3; then the heater 5 is turned on, and the heater 5 heats the water in the water tank 1 to generate water vapor, and then the respirator is activated, and the respirator delivers high-pressure oxygen to the water tank 1 through the air intake mechanism 2. The oxygen drives the stirring mechanism 4 to rotate and enters the water in the water tank 1 at the same time. The heated water heats the oxygen, and the oxygen drives the stirring mechanism 4 to rotate. The stirring mechanism 4 stirs the water vapor and oxygen so that the water vapor and oxygen are mixed, thereby humidifying the oxygen. At the same time, the stirring mechanism 4 stirs the water in the water tank 1, so that the water in the water tank 1 can be heated more evenly; finally, the heated and humidified oxygen is delivered to the oxygen mask through the air delivery mechanism 3, so that critically ill patients can feel more comfortable when using the respirator.

[0038] See also Figure 1-Figure 5 In other embodiments, the air intake mechanism 2 includes an air intake pipe 21 and a one-way assembly; one end of the air intake pipe 21 extends into the water tank 1 and is fixedly connected to the water tank 1. The air intake pipe 21 is coaxially arranged with the air delivery mechanism 3, and the stirring mechanism 4 is rotatably mounted on the air intake pipe 21 at the end away from the air delivery mechanism 3; a plurality of drive ports 22 are provided on the side of the air intake pipe 21, and the air intake pipe 21 is connected to the water tank 1 through the drive ports 22; the plurality of drive ports 22 are arranged in a circular array about the axis of the air intake pipe 21, and the drive ports 22 are arranged obliquely in the radial direction of the air intake pipe 21, with the opening of the drive ports 22 facing the stirring mechanism 4; the one-way assembly controls the one-way air intake of the air intake pipe 21 into the water tank 1. Furthermore, a first connector 26 is mounted on the end of the air intake pipe 21 located outside the water tank 1; the first connector 26 is detachably connected to the pipe of the ventilator.

[0039] During specific implementation, one end of the ventilator is connected to the air inlet pipe 21; the ventilator introduces oxygen into the air inlet pipe 21, and after the oxygen enters the air inlet pipe 21, it passes through the one-way component, which prevents the water in the water storage tank 1 from entering the air inlet pipe 21, and then the oxygen is discharged through the driving port 22; when the oxygen is discharged through the inclined driving port 22, the oxygen exerts a certain component force on the stirring mechanism 4 in the tangential direction, so that the oxygen can drive the stirring mechanism 4 to rotate through the inclined driving port 22, and at the same time discharge the oxygen into the water storage tank 1.

[0040] See also Figure 1-Figure 5In other embodiments, the one-way component is installed in the air intake pipe 21, and the one-way component includes a spring 23, a sliding plug 24 and a limiting ring 25; one end of the spring 23 abuts against one end of the air intake pipe 21 located in the water storage tank 1, and the other end of the spring 23 is fixedly connected to the sliding plug 24; the sliding plug 24 slides with the air intake pipe 21; the limiting ring 25 is coaxially fixedly connected to the air intake pipe 21, and the drive port 22 is located between the limiting ring 25 and the spring 23.

[0041] When the ventilator is working, oxygen pushes the sliding plug 24 to slide toward the spring 23 in the air inlet pipe 21, compressing the spring 23 while the sliding plug 24 moves to above the driving port 22, so that the air inlet pipe 21 is connected with the water storage tank 1 through the driving port 22, thereby opening the driving port 22; when the ventilator stops working or the thrust of oxygen is less than the elastic force of the spring 23, the spring 23 pushes the sliding plug 24 to slide toward the limiting ring 25 in the air inlet pipe 21. After the sliding plug 24 abuts the limiting ring 25, the sliding plug 24 blocks the driving port 22, thereby limiting the water in the water storage tank 1 from entering the air inlet pipe 21.

[0042] See also Figures 1-6 In other embodiments, the gas delivery mechanism 3 includes a gas delivery pipe 31 and a second connecting member 32. One end of the gas delivery pipe 31 extends into the water storage tank 1 and is fixedly connected to the water storage tank 1. The gas delivery pipe 31 is coaxially arranged with the air intake mechanism 2. The end of the stirring mechanism 4 away from the air intake mechanism 2 is rotatably mounted on the gas delivery pipe 31. The second connecting member 32 is mounted on the other end of the gas delivery pipe 31. The oxygen mask is detachably connected to the gas delivery pipe 31 via the second connecting member 32.

[0043] See also Figure 1-Figure 7 In other embodiments, the stirring mechanism 4 includes stirring blades 41 and a connecting ring 42; multiple stirring blades 41 are arranged in a circular array along the axis of the air intake mechanism 2, and both ends of each stirring blade 41 are fixedly mounted on the connecting ring 42; one of the connecting rings 42 is rotatably mounted on the air intake mechanism 2, and the other connecting ring 42 is rotatably mounted on the air delivery mechanism 3.

[0044] During specific implementation, the gas delivered by the air intake mechanism 2 applies a thrust to the stirring blades 41, so that the multiple stirring blades 41 rotate around the air intake mechanism 2 through the connecting ring 42, thereby stirring the water and gas in the water storage tank 1; by stirring the water, the water in the water storage tank 1 can be heated more evenly; by stirring the gas, the water vapor and oxygen can be mixed more evenly.

[0045] See also Figure 1-Figure 7In other embodiments, the cross-section of the stirring blade 41 along the axis of the air intake mechanism 2 is arc-shaped and curved in the direction opposite to the rotation of the stirring blade 41. When oxygen is ejected from the air intake mechanism 2, the oxygen contacts the curved inner side of the stirring blade 41, thereby increasing the resistance of the stirring blade 41 to the oxygen, thereby increasing the utilization rate of the oxygen thrust. At the same time, the curved outer side of the stirring blade 41 pushes the water flow to move, which can also reduce the resistance of the water flow to the stirring blade 41.

[0046] See also Figure 1 In another embodiment, a fixing mechanism 6 is further included, and the fixing mechanism 6 is used to fix the water tank 1. The water tank 1 is fixed by the fixing mechanism 6, so as to effectively prevent the water tank 1 from shaking, which causes the water in the water tank 1 to enter the gas transmission mechanism 3. Further, the fixing mechanism 6 can be the following structure, including a rotating shaft 61, a connecting plate 62 and a fixing portion 63; the rotating shafts 61 are respectively provided on opposite sides of the water tank 1 in the radial direction, and the rotating shafts 61 are located at one end of the water tank 1 close to the gas transmission mechanism 3, and the rotating shafts 61 are fixedly connected to the water tank 1; each rotating shaft 61 is installed on the fixing portion 63 through the connecting plate 62, and the rotating shaft 61 is arranged perpendicular to the connecting plate 62. The rotating shaft 61 is rotatably installed at one end of the connecting plate 62, and the other end of the connecting plate 62 is fixedly connected to the fixing portion 63; the fixing portion 63 can be detachably fixed to other objects.

[0047] Specifically, the fixing portion 63 can be a suction cup, a spring 23 clip, or fixed by a bolt. The fixing portion 63 is fixed to other objects. Under the action of gravity, the water tank 1 drives the rotating shaft 61 to rotate on the connecting plate 62, so that the bottom of the water tank 1 falls vertically, thereby effectively preventing the water tank 1 from shaking, causing the water in the water tank 1 to enter the gas transmission mechanism 3.
