Technical Field

[0003] A Chinese patent with publication number CN215608583U discloses an integrated atomizing and humidifying oxygen supply device, including a transparent mask and a humidifying device. The feature is that a middle connecting block is fixedly connected to the left side wall of the transparent mask. This application can greatly improve the patient's comfort and prevent bacteria from entering when the gas inside the mask is discharged to the outside, effectively reducing the threat of germs to the patient's health.

[0004] In clinical treatment, nebulizers and humidifiers provide important support, especially for patients with respiratory diseases. When using nebulizers and humidifiers to treat patients, traditional oxygen supply devices can reduce the bacteria that enter when the gas inside the mask is exhausted.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figures 1 to 6As shown in the embodiment of the present invention, an integrated oxygen supply device for nebulization and humidification includes a nebulizer 1; a first conduit 11 is fixedly connected to the outer wall of the nebulizer 1; a shunt pipe 12 is slidably connected to the inner wall of the first conduit 11; a second conduit 13 is slidably connected to the side of the shunt pipe 12 away from the first conduit 11; a connecting box 14 is fixedly connected to the bottom end of the second conduit 13; a third conduit 15 is fixedly connected to the outer wall of the nebulizer 1 and below the first conduit 11; a fourth conduit 16 is fixedly connected to the bottom end of the connecting box 14, and the third conduit 15 and the fourth conduit 16 slide against each other. A shunt tube 12 is connected; an air tube 17 is fixed to the outer wall of the middle part of the connecting box 14; a mixing mechanism is provided on the outer wall of the nebulizer 1, which is used to mix the nebulized medicine with humidified oxygen; when using the nebulizer humidifier to treat patients, the nebulizer 1 serves as the main body of the nebulizer humidifier, with the first conduit 11 and the third conduit 15 respectively connected to the nebulizer 1. A vent for controlling the connection is provided on the shunt tube 12. This oxygen supply device has three oxygen supply modes. The first mode is for patients who need separate delivery of nebulized medicine. The nebulizer 1 contains... The first mode involves nebulizing the medication and introducing it into catheter 11. The nebulized medication is then delivered to the connection box 14 via the connecting shunt tube 12 and catheter 13. Subsequently, the nebulized medication is delivered to the patient through the trachea 17 and an external mask. The second mode is for patients requiring separate humidified oxygen delivery. Humidified oxygen is introduced into catheter 15 from the nebulizer 1. The humidified oxygen is then delivered to the connection box 14 via the connecting shunt tube 12 and catheter 16. Subsequently, the humidified oxygen is delivered to the patient through the trachea 17 and an external mask. The third mode is for patients requiring a mixture of nebulized medication and humidified oxygen. The oxygen supply machine 1 simultaneously introduces nebulized medication and humidified oxygen into tubing 11 and tubing 3, respectively. The nebulized medication and humidified oxygen are then mixed in a mixing mechanism, which then introduces the mixed gas into the connecting box 14. Finally, the mixed gas is delivered to the patient through the trachea 17 and an external mask. By nebulizing the liquid medication and humidifying the oxygen, different fluids can be delivered individually or in combination. This allows for flexible adjustment of the oxygen supply mode according to the patient's condition, replacing traditional machines that use a fixed mode for oxygen supply, improving treatment effectiveness, and reducing the probability of exacerbating the patient's condition.

[0031] One-way valves are fixedly connected to the connection points of the second conduit 13 and the fourth conduit 16 with the connecting box 14; a first sealing plate 18 is fixedly connected to the inner wall of the second conduit 13; a second sealing plate 19 is fixedly connected to the inner wall of the third conduit 15; when delivering the nebulized medicine, the first sealing plate 18 can flexibly control the sealing of the tail end of the diversion pipe 12 between the first conduit 11 and the second conduit 13 according to the location of the diversion pipe 12. When the diversion pipe 12 slides close to the first conduit 11, the first conduit 11 is diverted... The air vent of pipe 12 is connected to the second conduit 13. The diverter pipe 12 is offset and blocked from the mixing mechanism, allowing the atomized drug solution to be delivered separately. When the diverter pipe 12 slides to the center between the first conduit 11 and the second conduit 13, the first conduit 11 is connected to the mixing mechanism through the air vent of the diverter pipe 12. The first sealing plate 18 blocks the air vent at the tail of the diverter pipe 12, allowing the atomized drug solution to be mixed and delivered. The one-way valve on the second conduit 13 prevents backflow. When the diverter pipe 12 slides close to the second conduit 13, the air vent of the first conduit 11 and the diverter pipe 12... When the orifice is not connected, the delivery of atomized medicine stops. During the delivery of humidified oxygen, the second sealing plate 19 can flexibly control the sealing of the head of the shunt pipe 12 between the third conduit 15 and the fourth conduit 16, depending on the location of the shunt pipe 12. When the shunt pipe 12 slides close to the third conduit 15, the third conduit 15 blocks the air vent of the shunt pipe 12 through the second sealing plate 19, thus preventing communication between the third conduit 15 and the shunt pipe 12 and stopping the delivery of humidified oxygen. When the shunt pipe 12 slides between the third conduit 15 and the fourth conduit 16... When the fourth conduit 16 is centered, the third conduit 15 connects to the mixing mechanism through the air hole of the splitter pipe 12. The air hole at the tail of the splitter pipe 12 is blocked inside the fourth conduit 16, and the humidified oxygen is mixed and delivered. The one-way valve on the fourth conduit 16 prevents backflow. When the splitter pipe 12 slides close to the fourth conduit 16, the third conduit 15 connects to the fourth conduit 16 through the air hole of the splitter pipe 12. The splitter pipe 12 and the mixing mechanism are misaligned and blocked, and the humidified oxygen is delivered separately. This plays a role in controlling the delivery of the atomized medicine and the humidified oxygen.

[0032] The mixing mechanism includes a fixed plate 2, a snap-fit ​​plate 21, and a transmission assembly. The fixed plate 2 is fixed to the outer wall of the nebulizer 1. The snap-fit ​​plate 21 is mounted on the fixed plate 2. The transmission assembly is mounted on the outer wall of the fixed plate 2 and is used to drive the two shunt tubes 12 to slide synchronously. Both the upper and lower ends of the snap-fit ​​plate 21 are provided with flow holes 22. When the nebulized medicine and humidified oxygen are mixed and delivered, the mixing chamber formed by the snap-fit ​​plate 2 and the snap-fit ​​plate 21 is driven by the transmission assembly to slide the two shunt tubes 12, so that the delivery channel is connected to the mixing chamber through the two flow holes 22. The nebulized medicine and humidified oxygen are delivered into the mixing chamber through the two shunt tubes 12 respectively. After the nebulized medicine and humidified oxygen are mixed in the mixing chamber, they are delivered to the patient through the connecting box 14 and the trachea 17, thus playing the role of mixing and delivering the nebulized medicine and humidified oxygen.

[0033] like Figures 1 to 3 , Figure 5 As shown, the transmission assembly includes an electric slider 3, a short rod 31, a sliding plate 32, and a first long plate 33. The electric slider 3 is slidably connected to the outer wall of the fixed plate 2. The short rod 31 is fixedly connected to the electric slider 3. The sliding plate 32 is slidably connected to the fixed plate 2, and the short rod 31 is inserted into the sliding plate 32. The first long plate 33 is fixedly connected to the outer wall of the diverter pipe 12 near the fixed plate 2. When the two diverter pipes 12 are controlled to slide, the short rod 31 on the electric slider 3 is engaged in the inner wall of the sliding plate 32. After the electric slider 3 is energized, it drives the two diverter pipes 12 to slide. When the device is near the nebulizer 1, it delivers nebulized medicine liquid only, without delivering humidified oxygen. When the electric slider 3 is energized, it drives the two shunt tubes 12 to slide close to the connecting box 14, delivering humidified oxygen only, without delivering nebulized medicine liquid. When the electric slider 3 is energized, it drives the two shunt tubes 12 to slide and is located in the center between the first conduit 11 and the second conduit 13, delivering a mixture of nebulized medicine liquid and humidified oxygen. The two first long plates 33 are mainly used to block the two flow holes 22 when switching delivery modes, and play a role in controlling the fluid mixing and switching delivery modes by driving the two shunt tubes 12 to slide.

[0034] like Figures 1 to 6 As shown, a connecting frame 4 is fixedly connected to the outer wall of the sliding plate 32; a switching plate 41 is fixedly connected to one end of the connecting frame 4 away from the sliding plate 32, and the switching plate 41 is slidably connected to the inner wall of the connecting box 14; a second long plate 42 is fixedly connected to the outer wall of the connecting frame 4, and the second long plate 42 is attached to the outer wall of the connecting box 14; guide plates 43 are fixedly connected to both sides of the inner wall of the connecting box 14 near the switching plate 41; when the atomized medicine and humidifying oxygen are mixed and transported, the second long plate 42 and the switching plate 41 on the connecting frame 4 move along with the sliding plate 32. The sliding plate 41 is located at the center between the two guide plates 43, at which point the mixing chamber is connected to the air pipe 17 through the connecting box 14. When the atomized medicine is delivered separately, the switching plate 41 slides along with the sliding plate 32 to block the guide plate 43 near the mixing chamber, thus blocking the mixing chamber and preventing the atomized gas from entering the mixing chamber. When the humidified oxygen is delivered separately, the switching plate 41 slides along with the sliding plate 32 to block the guide plate 43 away from the mixing chamber, thus blocking the mixing chamber and preventing the humidified oxygen from entering the mixing chamber. This serves to control and block the mixing chamber.

[0035] like Figures 1 to 4 , Figure 6 , Figure 7As shown, two flow equalization plates 5 are fixedly connected to the inner wall of the snap-fit ​​plate 21; the openings on the flow equalization plates 5 correspond to the flow holes 22; when the atomized medicine and humidified oxygen are mixed and transported, the atomized medicine and humidified oxygen are transported into the mixing chamber respectively, and the atomized medicine and humidified oxygen are respectively passed into the flow equalization plates 5 connected by the flow holes 22. The two flow equalization plates 5 evenly pass the atomized medicine and humidified oxygen into the mixing chamber, thereby improving the mixing effect of the atomized medicine and humidified oxygen.

[0036] like Figures 1 to 4 , Figure 6 As shown, a servo motor 6 is fixedly connected to the inner wall of the nebulizing oxygen supply machine 1; a fan blade 61 is fixedly connected to the output end of the servo motor 6, and the fan blade 61 is located between the fixed plate 2 and the snap-fit ​​plate 21; a sensor 62 is fixedly connected to the outer wall of the fixed plate 2; a trapezoidal plate 63 is slidably connected to the sensor 62 through a first elastic element; when the nebulized medicine and humidified oxygen are introduced into the mixing chamber for mixing and delivery, the output end of the servo motor 6 drives the fan blade 61 to rotate, and the fan blade 61 blows the mixed gas into the connecting box 14 for delivery, improving the delivery effect of the mixed gas. At the same time, the electric slider 3 drives the sliding plate 32 to slide and squeeze the trapezoidal plate 63 into the sensor 62. The first elastic element contracts and is subjected to force. The sensor 62 is a pressure sensor. After the sensor 62 is subjected to pressure, it sends a signal to the main controller. The main controller controls the servo motor 6 to be powered on and run. When the sliding plate 32 moves away from the trapezoidal plate 63, the first elastic element elastically squeezes the trapezoidal plate 63 to reset, and the servo motor 6 is powered off and stops working, which plays the role of controlling the start and stop of the servo motor 6.

[0037] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, multiple square plates 7 are fixed to the inner wall of the snap-fit ​​plate 21; the multiple square plates 7 are evenly distributed between the fixed plate 2 and the snap-fit ​​plate 21; when the atomized drug solution and humidified oxygen are introduced into the mixing chamber, the fan blade 61 rotates and blows the mixed gas through the evenly distributed multiple square plates 7, so that the blown mixed gas forms turbulence. The turbulence can enhance the mixing of the atomized drug solution and humidified oxygen. The disordered vortex of the turbulence can make the atomized drug solution and humidified oxygen fully collide and diffuse, reduce the sedimentation of the drug in the mixing chamber, make the mixing more uniform, ensure that the ratio of drug and oxygen inhaled by the patient is similar, and reduce the fluctuation of the treatment effect.

[0038] A guide block 8 is fixed to the inner wall of the snap-fit ​​plate 21; the side of the guide block 8 near the fan blade 61 is set as a flared opening; when the atomized medicine and humidified oxygen are mixed and introduced into the connection box 14, the guide block 8 is fixed to the inner wall of the snap-fit ​​plate 21 near the connection box 14, and the mixed gas is guided and transported through the flared opening of the guide block 8, which can improve the efficiency of the mixed gas being discharged from the mixing chamber to the outside.

[0039] like Figures 1 to 4 , Figure 6 As shown, the outer wall of the atomizing oxygen supply machine 1 is fixedly connected to a fixing block 9, and the side of the fixing block 9 near the snap-fit ​​plate 21 is set as an inclined surface; the inner wall of the fixing block 9 is slidably connected to the limiting plate 91 through the second elastic element; when the mixing chamber is used for maintenance for a long time, the snap-fit ​​plate 21 is removed from the fixing plate 2, and the inner walls of the fixing plate 2 and the snap-fit ​​plate 21, as well as various components, are maintained and sterilized. After the treatment is completed, the snap-fit ​​plate 21 is grasped and pushed between the two fixing blocks 9. The inclined surfaces of the two fixing blocks 9 guide and squeeze the two limiting plates 91 to retract. The second elastic element is squeezed and contracted under force, and the limiting plate 91 slides into the interior of the fixing block 9 until the snap-fit ​​plate 21 and the fixing plate 2 are spliced ​​to form a mixing chamber. The two second elastic elements spring and squeeze the two limiting plates 91 to reset. The two limiting plates 91, together with the two fixing blocks 9, limit the snap-fit ​​plate 21, which plays a role in assembling, sterilizing and maintaining the mixing chamber.

[0040] Working Process: When using the nebulizer-humidifier integrated oxygen supply machine to treat patients, the nebulizer-humidifier 1 serves as the main body of the integrated oxygen supply device. The first conduit 11 and the third conduit 15 are connected to the nebulizer-humidifier 1. The shunt pipe 12 is equipped with a control vent. This oxygen supply device has three oxygen supply modes. The first mode is for patients requiring separate delivery of nebulized medication. The medication is atomized inside the nebulizer-humidifier 1 and then introduced into the first conduit 11. The atomized medication is then delivered to the connecting box 14 via the connected shunt pipe 12 and the second conduit 13. Subsequently, the atomized medication is delivered to the patient through the trachea 17 and the external mask. The second mode is for patients requiring separate delivery of humidified oxygen. The nebulizer-humidifier 1 internally humidifies... Oxygen is introduced into catheter 15 (number 3), and humidified oxygen is delivered to the connecting box 14 via the connecting splitter tube 12 and catheter 16. The humidified oxygen is then delivered to the patient via the trachea 17 and an external mask. The third mode is for patients requiring a mixture of nebulized medication and humidified oxygen. The nebulizer 1 simultaneously introduces nebulized medication and humidified oxygen into catheters 11 and 15 respectively. The nebulized medication and humidified oxygen are mixed in the mixing mechanism, which then introduces the mixed gas into the connecting box 14. Finally, the mixed gas is delivered to the patient via the trachea 17 and an external mask. This method atomizes the liquid medication and humidifies the oxygen, delivering different fluids individually or in mixture, depending on the patient's needs. The oxygen supply mode can be flexibly adjusted according to the patient's condition, replacing the traditional machine that uses a fixed mode for oxygen supply, improving the treatment effect and reducing the probability of the patient's condition worsening. During the delivery of nebulized medication, the first sealing plate 18 can flexibly control the sealing of the tail of the shunt tube 12 between the first conduit 11 and the second conduit 13 based on the position of the shunt tube 12. When the shunt tube 12 slides close to the first conduit 11, the first conduit 11 connects to the second conduit 13 through the air hole of the shunt tube 12, and the shunt tube 12 is misaligned with the mixing mechanism for sealing, allowing the nebulized medication to be delivered separately. When the shunt tube 12 slides to the center between the first conduit 11 and the second conduit 13, the first conduit 11 connects to the mixing mechanism through the air hole of the shunt tube 12. When the combined mechanism is connected, the first sealing plate 18 blocks the air hole at the tail of the shunt pipe 12, and the atomized medicine is mixed and transported. The one-way valve on the second conduit 13 prevents backflow. When the shunt pipe 12 slides close to the second conduit 13, the air hole of the first conduit 11 and the shunt pipe 12 are not connected, and the delivery of the atomized medicine stops. When delivering humidified oxygen, the second sealing plate 19 can flexibly control the blocking of the head of the shunt pipe 12 according to the location of the other shunt pipe 12 between the third conduit 15 and the fourth conduit 16. When the shunt pipe 12 slides close to the third conduit 15, the third conduit 15 blocks the air hole of the shunt pipe 12 through the second sealing plate 19, so that the third conduit 15 and the shunt pipe 12 are not connected, and the delivery of humidified oxygen stops.When the shunt tube 12 slides to the center between the third conduit 15 and the fourth conduit 16, the third conduit 15 connects to the mixing mechanism through the air hole of the shunt tube 12, and the air hole at the tail of the shunt tube 12 is blocked inside the fourth conduit 16, allowing for the mixed delivery of humidified oxygen. A one-way valve on the fourth conduit 16 prevents backflow. When the shunt tube 12 slides close to the fourth conduit 16, the third conduit 15 connects to the fourth conduit 16 through the air hole of the shunt tube 12, and the shunt tube 12 is misaligned and blocked from the mixing mechanism, allowing for the separate delivery of humidified oxygen. This serves to control the delivery of the atomized medicine and humidified oxygen. During delivery, the mixing chamber formed by the locking plate 2 and the snap-fit ​​plate 21 is driven by the transmission assembly to slide the two shunt tubes 12, so that the delivery channel connects to the two flow holes 22 and enters the mixing chamber. The nebulized medicine and humidified oxygen are delivered into the mixing chamber through the two shunt tubes 12 respectively. After the nebulized medicine and humidified oxygen are mixed in the mixing chamber, they are delivered to the patient through the connecting box 14 and the trachea 17, which plays the role of mixing and delivering the nebulized medicine and humidified oxygen. When the sliding of the two shunt tubes 12 is controlled, the short rod 31 on the electric slider 3 is locked in the inner wall of the sliding plate 32. After the electric slider 3 is energized, it drives the two shunt tubes 12 to slide closer together. When the nebulizer oxygen supply unit 1 is in operation, it delivers nebulized medicine liquid only, without delivering humidified oxygen. When the electric slider 3 is energized and drives the two diverter pipes 12 to slide close to the connecting box 14, it delivers humidified oxygen only, without delivering nebulized medicine liquid. When the electric slider 3 is energized and drives the two diverter pipes 12 to slide to the center between the first conduit 11 and the second conduit 13, it delivers a mixture of nebulized medicine liquid and humidified oxygen liquid. The two first-order long plates 33 are mainly used to block the two flow holes 22 when switching delivery modes, and play a role in controlling the fluid mixing and switching delivery modes by driving the two diverter pipes 12 to slide. When the nebulized medicine liquid and humidified oxygen liquid are delivered together, the connecting box 14 is connected to the connecting box 14. The second long plate 42 and the switching plate 41 on the frame 4 slide together with the sliding plate 32 and are positioned at the center between the two guide plates 43. At this time, the mixing chamber is connected to the air pipe 17 through the connecting box 14. When the atomized medicine is delivered separately, the switching plate 41 slides together with the sliding plate 32 to block the guide plate 43 near the mixing chamber. At this time, the mixing chamber is blocked to prevent the atomized gas from entering the mixing chamber. When the humidified oxygen is delivered separately, the switching plate 41 slides together with the sliding plate 32 to block the guide plate 43 away from the mixing chamber. At this time, the mixing chamber is blocked to prevent the humidified oxygen from entering the mixing chamber. This serves to control and block the mixing chamber.

[0041] When the atomized drug solution and humidified oxygen are mixed and delivered, the atomized drug solution and humidified oxygen are delivered into the mixing chamber separately, and the atomized drug solution and humidified oxygen are respectively passed into the flow equalization plate 5 connected by the flow hole 22. The two flow equalization plates 5 evenly pass the atomized drug solution and humidified oxygen into the mixing chamber, thereby improving the mixing effect of the atomized drug solution and humidified oxygen.

[0042] When the atomized medicine and humidified oxygen are introduced into the mixing chamber for mixing and delivery, the output of the servo motor 6 drives the fan blade 61 to rotate. The fan blade 61 blows the mixed gas into the connecting box 14 for delivery, improving the delivery effect of the mixed gas. At the same time, the electric slider 3 drives the sliding plate 32 to slide and squeeze the trapezoidal plate 63 into the sensor 62. The first elastic element contracts and is subjected to force. The sensor 62 is a pressure sensor. After the sensor 62 is subjected to pressure, it sends a signal to the main controller. The main controller controls the servo motor 6 to be powered on and run. When the sliding plate 32 moves away from the trapezoidal plate 63, the first elastic element elastically squeezes the trapezoidal plate 63 to reset. The servo motor 6 is powered off and stops working, which plays the role of controlling the opening and closing of the servo motor 6.

[0043] When the nebulized medication and humidified oxygen are introduced into the mixing chamber, the fan blades 61 rotate and blow the mixed gas through multiple evenly distributed square plates 7, causing the blown mixed gas to form turbulence. The turbulence can enhance the mixing of the nebulized medication and humidified oxygen. The disordered vortex of the turbulence can allow the nebulized medication and humidified oxygen to collide and diffuse fully, reduce the sedimentation of the drug in the mixing chamber, make the mixing more uniform, ensure that the ratio of drug and oxygen inhaled by the patient is similar, and reduce the fluctuation of the treatment effect.

[0044] When the atomized medicine and humidified oxygen are mixed and introduced into the connection box 14, the guide block 8 is fixed to the inner wall of the snap plate 21 near the connection box 14. The mixed gas is guided and transported through the flared mouth of the guide block 8, which can improve the efficiency of the mixed gas being discharged from the mixing chamber to the outside.

[0045] When the mixing chamber is used for a long time and needs maintenance, the snap-fit ​​plate 21 is removed from the fixing plate 2. The inner walls of the fixing plate 2 and the snap-fit ​​plate 21, as well as all the components, are then sterilized. After the sterilization is completed, the snap-fit ​​plate 21 is pushed between the two fixing blocks 9. The inclined surfaces of the two fixing blocks 9 guide the two limiting plates 91 to retract. The second elastic element is compressed and subjected to force, and the limiting plate 91 slides into the interior of the fixing block 9. After the snap-fit ​​plate 21 and the fixing plate 2 are spliced ​​together to form the mixing chamber, the two second elastic elements spring and press the two limiting plates 91 to reset. The two limiting plates 91, together with the two fixing blocks 9, limit the snap-fit ​​plate 21, thus playing a role in assembling, sterilizing and maintaining the mixing chamber.
