When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] refer to Figures 1 to 5 , it should be understood that Figure 5 The connections between the components should be like Figure 2 As compact as in the example, this is just an example. Figure 5 The middle part of the components is displayed separately for easy understanding. An embodiment of the present application provides a medical nebulizer, which may include a main body 1, a first rotating shaft 2, a rotating rod 3, a torsion spring 4 and a clamping rod 5. The main body 1 has a top surface and a bottom surface relatively arranged in its own height direction; the first rotating shaft 2 is fixed to the side of the top surface away from the bottom surface and its axial direction is the same as the length direction of the main body 1; the rotating rod 3 is rotatably connected to the first rotating shaft 2 and has the freedom to rotate around the first rotating shaft 2, and one end of the rotating rod 3 extends out of the top surface; the torsion spring 4 is sleeved on the outer periphery of the rotating rod 3, and the two ends of the torsion spring 4 are respectively connected to the rotating rod 3 and the main body 1, and the torsion spring 4 provides the rotating rod 3 with a driving force for rotating around the first rotating shaft 2, so that the end of the rotating rod 3 located inside the top surface is away from the top surface; the clamping rod 5 is fixed to the end of the rotating rod 3 located outside the top surface, and the rotating rod 3 drives the end of the clamping rod 5 away from the rotating rod 3 to be close to the side wall of the main body 1 in response to the driving force.

[0028] The embodiment of the present application proposes a medical nebulizer. When in use, pressing the end of the rotating rod 3 located inside the top surface causes the rotating rod 3 to rotate axially around the first rotating shaft 2. At this time, the end of the rotating rod 3 located inside the top surface is close to the top surface, and a gap is created between the end of the clamping rod 5 away from the rotating rod 3 and the main body 1, clamping the main body 1 on the back plate 8 of the bed. At this time, the main body 1 and the clamping rod 5 are respectively located on both sides of the back plate 8 of the bed, and the main body 1 is in contact with the back plate 8 of the bed, and the top of the back plate 8 is in contact with the rotating rod 3. The torsion spring 4 drives the rotating rod 3 to rotate, so that the end of the clamping rod 5 away from the rotating rod 3 is close to the back plate 8 of the bed, so that the main body 1 can be fixed on the bed. When using the medical nebulizer, no matter the patient moves or other people accidentally touch the medical nebulizer, it will not cause the nebulizer to fall, and it is safer and more convenient to use.

[0029] Specifically, the main body 1 is the main part of the nebulizer. A connecting tube connected to it is provided on the main body 1. A mask is provided at one end of the connecting tube away from the main body 1. After the nebulizer is fixed on the back plate 8 of the bed, the patient can wear the mask to use the nebulizer.

[0030] The main body 1 is similar to a rectangular structure, having a length, a width and a height, and the length direction, the width direction and the height direction of the main body 1 are perpendicular to each other.

[0031] It should be understood that the torsion spring 4 is used to apply torque to the rotating rod 3 so that the rotating rod 3 rotates around the first rotating axis 2, and the end of the rotating rod 3 located inside the top surface gradually moves away from the top surface. When the atomizer is not in use, the torsion spring 4 will push the steering rod 3 to rotate, so that the end of the clamping rod 5 away from the rotating rod 3 is close to the side wall of the main body 1.

[0032] refer to Figure 1 and Figure 3 In an exemplary embodiment, there are two rotating rods 3, two torsion springs 4 and two clamping rods 5, and they are spaced apart in the length direction of the main body 1; the medical nebulizer may also include a handle 31, a first connecting shaft 32 and a second connecting shaft 33, the handle 31 is fixed to one end of the two rotating rods 3 located inside the top surface; the first connecting shaft 32 is fixed to one end of the two rotating rods 3 close to the clamping rod 5 and its axial direction is the same as the length direction of the main body 1; the second connecting shaft 33 is fixed to one end of the two clamping rods 5 away from the rotating rod 3 and its axial direction is the same as the length direction of the main body 1.

[0033] Specifically, such as Figure 1 As shown, pressing the handle 31 can drive the two clamping rods 5 to move away from one end of the rotating rod 3 and form a gap between the main body 1, and then the nebulizer is set on the back plate 8 of the bed. At this time, the two torsion springs 4 respectively drive one rotating rod 3 to rotate, and each rotating rod 3 further drives each clamping rod 5 to move away from one end of the rotating rod 3 and close to the side wall of the main body 1. In this way, when the nebulizer is fixed to the back plate 8 of the bed through the main body 1 and the clamping rod 5, there are two force application points on one side of the clamping rod 5, and the clamping is more stable.

[0034] Furthermore, when moving the atomizer, it is only necessary to lift the handle 31 to move it. At this time, the end of the clamping rod 5 away from the rotating rod 3 contacts the side wall of the main body 1.

[0035] refer to Figure 3 and Figure 4In an exemplary embodiment, the medical nebulizer may further include a resistance assembly; the resistance assembly may include a rotating block 51 and a contact block 52, the rotating block 51 is sleeved on the outer periphery of the second connecting shaft 33 and is rotatably connected to the second connecting shaft 33, and the rotating block 51 has the freedom of axial rotation around the second connecting shaft 33; the contact block 52 is fixed to the side of the rotating block 51 facing the main body 1, wherein the clamping rod 5 is in resistance with the main body 1 through the contact block 52.

[0036] Specifically, such as Figure 4 As shown, a resistance component is provided at one end of the clamping rod 5 away from the rotating rod 3, and the clamping rod 5 is in resistance with the main body 1 or the bed backboard 8 through the resistance component. At this time, the contact area between the bed backboard 8 or the main body 1 and the contact block 52 is much larger than the contact area between the bed backboard 8 or the main body 1 and the clamping rod 5. The pressure on the bed backboard 8 or the main body 1 is smaller and it is not easy to be damaged.

[0037] Furthermore, when clamping the bed backboard 8 of different thicknesses, the rotating block 51 can rotate around the axial direction of the second connecting shaft 33, so that the contact block 52 will rotate through the rotating block 51 after contacting the bed backboard 8, so that the side of the contact block 52 in contact with the bed backboard 8 remains parallel to the bed backboard 8. The same is true for the contact block 52 in contact with the main body 1, which is not explained in detail here. In this way, the contact area between the contact block 52 and the bed backboard 8 or the main body 1 is guaranteed, further preventing damage to the bed backboard 8 or the main body 1.

[0038] refer to Figure 3 and Figure 4 In an exemplary embodiment, the interference assembly may further include a counterweight block 53 , which is fixed to a side of the rotating block 51 away from the contact block 52 and has the same weight as the contact block 52 .

[0039] Specifically, the counterweight block 53 ensures that the contact block 52 and the side of the main body 1 facing each other are always parallel. Similarly, the bed backboard 8 is mostly arranged perpendicular to the horizontal plane. In this way, when the contact block 52 contacts the main body 1 or the bed backboard 8, the contact block 52 almost does not need to rotate around the second connecting axis 33 to ensure the contact area between the contact block 52 and the bed backboard 8.

[0040] refer to Figure 3 and Figure 4 In an exemplary embodiment, the interference assembly may further include an interception shaft 54 ​​, which is disposed between the two clamping rods 5 and close to the rotating block 51 .

[0041] It should be understood that if Figure 4As shown, the closer the intercepting shaft 54 ​​is to the rotating block 51, the smaller the angular range of the rotating block 51 can rotate. This can effectively prevent the rotating block 51 from rotating at an excessive angle, causing the contact block 52 and the counterweight block 53 to reverse their positions, thereby ensuring that the contact block 52 can contact the bed backboard 8 or the main body 1.

[0042] refer to Figure 1 In an exemplary embodiment, the medical nebulizer may further include a gripping shaft 11, which is fixed to the side of the top surface facing away from the bottom surface and has an axial direction that is the same as the length direction of the main body 1, and there is a gap between the gripping shaft 11 and the main body 1; wherein, in the height direction of the main body 1, the gripping shaft 11 is located between the handle 31 and the main body 1; in the width direction of the main body 1, the gripping shaft 11 is located on the side of the handle 31 facing away from the rotating rod 3.

[0043] Specifically, such as Figure 1 As shown, before clamping the nebulizer on the bed backboard 8, the operator holds the gripping shaft 11 and the handle 31 with one hand and squeezes them tightly so that the handle 31 is close to the gripping shaft 11, thereby creating a gap between the contact block 52 and the main body 1. At this time, the nebulizer is installed on the bed backboard 8, the bed backboard 8 is located in the gap, and the top of the bed backboard 8 is in contact with the rotating rod 3. The operator releases his hand at this time to complete the fixation of the nebulizer. The operation can be completed with one hand, which is more convenient to use.

[0044] refer to Figure 1 and Figure 2 In an exemplary embodiment, the medical nebulizer may further include a second rotating shaft 61, a telescopic rod 62 and a limit assembly. The second rotating shaft 61 is rotatably connected between the two rotating rods 3 and is located between the handle 31 and the first connecting shaft 32. The axial direction of the second rotating shaft 61 is the same as the length direction of the main body 1 and has the freedom to rotate around its own axial direction; the telescopic rod 62 has the freedom to telescope in its own extension direction, one end of the telescopic rod 62 is fixed to the second rotating shaft 61, and the other end is rotatably connected to the main body 1 and has the freedom to rotate around the length direction of the main body 1; the limit assembly is arranged on a rotating rod 3 and connected to the second rotating shaft 61, and the limit assembly responds to an external driving force to lock or release the rotational freedom of the second rotating shaft 61.

[0045] Specifically, one end of the telescopic rod 62 is rotatably connected to the main body 1, and the other end is fixed to the second rotating shaft 61. When the rotating rod 3 rotates around the first rotating shaft 2, the telescopic rod 62 rotates along with the rotating rod 3, and the telescopic rod 62 is extended and retracted during the rotation process, that is, the telescopic rod 62 does not affect the rotation process of the rotating rod 3. When the limiting component prevents the second rotating shaft 61 from rotating, the end of the telescopic rod 62 connected to the second rotating shaft 61 cannot rotate. In this way, the rotating rod 3 is restricted by the telescopic rod 62 and cannot rotate around the first rotating shaft 2. That is, the limiting component can ultimately control whether the rotating rod 3 can rotate around the first rotating shaft 2.

[0046] Furthermore, when the nebulizer is clamped on the bed back plate 8, the rotating rod 3 is similar to a lever, and the contact area between the rotating rod 3 and the bed back plate 8 is the fulcrum of the lever. At this time, the rotating rod 3 is locked by the limiting component so that the rotating rod 3 cannot rotate around the first rotating shaft 2. In this way, when the main body 1 is subjected to external force, even if the external force can enable the rotating rod to overcome the resistance of the torsion spring 4 and has a tendency to rotate, the rotating rod 3 cannot rotate around the first rotating shaft 2, effectively preventing the rotating rod 3 from rotating and driving the contact block 52 to separate from the bed back plate 8, thereby ensuring the connection effect between the nebulizer and the bed back plate 8.

[0047] refer to Figure 2 and Figure 5 In an exemplary embodiment, one end of the second rotating shaft 61 close to the limiting assembly passes through the corresponding rotating rod 3, and the limiting assembly is located on the side of the corresponding rotating rod 3 away from the other rotating rod 3; the limiting assembly may include a fixed cylinder 71, a rotating cylinder 72 and at least two claws 73, the fixed cylinder 71 is fixed to the rotating rod 3 and is located on the outer periphery of the second rotating shaft 61, and the axial direction of the fixed cylinder 71 is the same as the axial direction of the second rotating shaft 61; the rotating cylinder 72 is threadedly connected to the inner periphery of the fixed cylinder 71, and the inner diameter of the rotating cylinder 72 gradually decreases in the direction away from the rotating rod 3; at least two claws 73 are slidably connected to the rotating rod 3 and have the freedom to slide along the radial direction of the second rotating shaft 61, and multiple claws 73 are arranged at intervals. It is placed on the outer periphery of the second rotating shaft 61 and contacts the inner periphery of the rotating cylinder 72; a plurality of sliding grooves 34 are provided on the side of the rotating rod 3 corresponding to the limiting assembly facing the claw 73, and the plurality of sliding grooves 34 correspond one-to-one to the plurality of claws 73 and all extend radially along the second rotating shaft 61; the limiting assembly can also include a plurality of sliders 74 and a plurality of springs 75, and the plurality of sliders 74 slide in correspondence with the plurality of sliding grooves 34, and each slider 74 is fixed to the corresponding claw 73; a plurality of springs 75 correspond one-to-one to the plurality of sliding grooves 34 and are arranged in the corresponding sliding grooves 34, and the extension direction of each spring 75 is the same as the extension direction of the corresponding sliding groove 34, and the two ends of each spring 75 are respectively connected to the slider 74 and the rotating rod 3.

[0048] Specifically, when there are two claws 73, the rotating cylinder 72 is rotated to make the rotating cylinder 72 close to the rotating rod 3, and the inner periphery of the rotating cylinder 72 gradually pushes the two claws 73 to approach the second rotating shaft 61 along the radial direction of the second rotating shaft 61, and finally the two claws 73 clamp the second rotating shaft 61 to prevent the second rotating shaft 61 from rotating. Among them, the more claws 73 there are, the better the effect of clamping the second rotating shaft 61.

[0049] When the rotating cylinder 72 is moved away from the rotating rod 3, the springs 75 are pressed against the locking cam 74, and the second locking cam 71 is released, so that the second rotating shaft 61 can be rotated around its own axis.

[0050] In an exemplary embodiment, an air inlet and an air outlet are provided on the main body 1; the medical nebulizer may also include a valve, a boosting device and an air supply pipe, the valve is provided at the air inlet; the boosting device is provided inside the main body 1; the air supply pipe connects the boosting device and the air outlet, wherein the valve is connected to the air supply pipe.

[0051] Specifically, the connecting pipe is connected to the air outlet, and the booster device provides pressure to push the atomizing airflow into the air supply pipe, the connecting pipe and the mask in sequence; when encountering emergencies such as power system failures, the valve can be connected through an external air source, and the external air source will pass the gas into the air supply pipe, and finally push the atomizing airflow into the connecting pipe and the mask in sequence. In this way, the atomizer can still work in the event of a power outage, and it is more convenient to use.

[0052] Furthermore, the valve is a one-way stop valve, that is, only gas can enter the air inlet. At the same time, a pressure reducing device is provided on the valve, which converts the external high-pressure gas source into low-pressure gas for the convenience of use of the atomizer.

[0053] Among them, the air supply pipe is also connected to a flow meter, which can display the current gas flow rate and use indicator lights or text to indicate whether the current flow rate is within a reasonable range, so as to facilitate adjustment and make it more convenient to use.
