Description

Technical Field

[0001] This application relates to the field of ventilator technology, and in particular to ventilators and their nebulizing humidification devices. Background Technology

[0002] Non-invasive ventilators are medical devices suitable for mild to moderate chronic obstructive pulmonary disease, neuromuscular or amyotrophic lateral sclerosis, obesity-related hypoventilation, Chernobyl respiration, and other conditions. In actual use, to ensure patients can use the ventilator normally for extended periods, non-invasive ventilators are typically equipped with a humidifier tank. This tank increases the humidity of the inhaled air, thereby improving comfort and providing a better breathing experience.

[0003] In related technologies, the humidification tanks equipped with ventilators typically use heating to evaporate water into water vapor, which is then carried out by airflow to achieve a humidification effect.

[0004] However, the water vapor produced by this humidification method is at a high temperature and cannot be directly inhaled by the patient through the ventilator. After cooling, it is easy to condense into water droplets, which increases the air resistance of the ventilator tubing and affects the ventilation effect. Utility Model Content

[0005] Therefore, it is necessary to provide a ventilator and its nebulizing humidification device to address the problem of poor ventilation caused by heating to generate water vapor.

The liquid inlet and the liquid outlet are connected. The side of the atomizing plate with the liquid inlet is sealed to the bottom of the water tank. The heating plate is used to heat the liquid inlet or the water mist in the mist outlet.

[0015] The atomizing humidification device includes a controller, which is electrically connected to the first temperature and humidity sensor, the second temperature and humidity sensor, and the atomizing heating module.

[0016] In one embodiment, the atomizing humidifier includes a display screen electrically connected to a controller, and the display screen is provided with a temperature button and a humidity button.

[0039] See Figures 1-3 An embodiment of this application provides an atomizing humidification device, which includes a water tank 100, an atomizing heating module 200, and a vent pipe 300. The water tank 100 is used to hold liquid, and a liquid outlet 111 is provided at the bottom of the water tank 100. The atomizing heating module 200 is disposed at the bottom of the water tank 100 and includes heating elements 210 and atomizing elements 220 stacked sequentially along the height direction. The atomizing elements 220 have a liquid inlet 221 and a mist outlet 222. The liquid inlet 221 is connected to the liquid outlet 111. The side of the atomizing elements 220 with the liquid inlet 221 is sealed to the bottom of the water tank 100. The heating elements 210 are used to heat the liquid inlet 221 or the water mist in the mist outlet 222. The interior of the vent pipe 300 is connected to the mist outlet 222, and the vent pipe 300 is sealed to the side of the atomizing elements 220 with the mist outlet 222.

[0040] In this embodiment, the liquid in the water tank 100 enters the inlet 221 of the atomizing plate 220 through the outlet 111. The atomizing plate 220 converts the liquid into water mist and sprays it into the ventilation tube 300 from the mist outlet 222. The atomizing plate 220 uses ultrasonic atomization or piezoelectric ceramic atomization to directly turn the liquid into tiny droplets, eliminating the need for heating. This avoids the problems of excessively high liquid vapor temperature or easy condensation into droplets caused by heating. In addition, the heating plate 210 and the atomizing plate 220 are stacked sequentially at the bottom of the water tank 100 to heat the liquid entering the atomizing plate 220 or the water mist exiting the atomizing plate 220, thereby ensuring that the temperature and humidity of the gas entering the patient's body through the ventilation tube 300 meet the requirements.

[0041] Furthermore, the atomizing plate 220 of this application is located at the liquid outlet 111 of the water tank 100, that is, the atomizing plate 220 isolates water and air from each other, so that the water in the water tank 100 will not damage the ventilator, and there is no need to design the ventilation tube 300 with multiple channels, so the structure is simple.

[0042] In some embodiments, the heating element 210 is sandwiched between the atomizing element 220 and the bottom of the water tank 100; the heating element 210 has a flow port 211, and the liquid outlet 111 and the liquid inlet 221 are respectively connected to the flow port 211; the two sides of the heating element 210 are respectively sealed to the bottom of the water tank 100 and the side of the atomizing element 220 with the liquid inlet 221.

[0043] In this embodiment, the heating element 210 is sealed to the bottom of the water tank 100 by bonding, welding, or screw connection. Preferably, the heating element 210 is bonded to the bottom of the water tank 100, which can effectively ensure the sealing effect between the heating element 210 and the water tank 100. The heating element 210 has a flow port 211 in the middle. When the liquid from the outlet 111 enters the inlet 221 through the flow port 211, the heating element 210 can heat the liquid passing through the flow port 211, so that the temperature of the water mist passing through the mist outlet 222 of the atomizing element 220 can meet the requirements. The bottom of the atomizing element 220 is sealed to the vent pipe 300, that is, the water mist sprayed through the mist outlet 222 can directly enter the vent pipe 300.

[0044] The atomizing plate 220 needs to vibrate to break the liquid into small particles. The atomization process takes a certain amount of time, so the liquid in the inlet 221 needs a certain amount of time to be atomized. During this process, the heating plate 210 is set on the side close to the inlet 221, which can use the atomization time to heat the liquid in the inlet 221, thereby ensuring the temperature of the water mist at the outlet 222.

[0045] In some other embodiments, the atomizing plate 220 is disposed on the side of the heating plate 210 near the water tank 100. The atomizing plate 220 is sealed to the bottom of the water tank 100. The liquid entering from the outlet 111 to the inlet 221 is atomized by the atomizing plate 220 and becomes water mist. The water mist is heated by the heating plate 210 and then enters the vent pipe 300.

[0046] It should be noted that the heating temperature of the heating pad 210 does not exceed 60 degrees Celsius. Medication can be added to the water tank 100. After being atomized by the nebulizer 220, the medication is formed into fine particles and can be inhaled by the patient through the ventilation tube 300.

[0047] Combination Figure 1 and Figure 2 In some embodiments, the ventilation tube 300 includes a connecting tube segment 310 and a heating tube segment 320 connected in sequence. The atomizing heating module 200 is connected to the connecting tube segment 310, and the heating tube segment 320 is disposed on the side of the connecting tube segment 310 near the breathing mask 610.

[0048] In this embodiment, one end of the ventilation tube 300 is connected to the ventilator body 620, and the other end is connected to the breathing mask 610. The water tank 100 is connected to the ventilation tube 300 between the ventilator and the breathing mask 610. Water mist of a certain temperature generated in the water tank 100 enters the ventilation tube 300 and flows towards the breathing mask 610 under the action of the gas blown out by the ventilator body 620, so as to provide the patient with gas that meets certain temperature and humidity requirements. The heating tube section 320 is located on one side of the breathing mask 610 to prevent the atomized water mist from condensing into condensate droplets during the flow process, which would affect the patient's breathing effect.

[0049] Specifically, the heating tube section 320 includes an inner tube and a heating wire wound around the outer side of the inner tube. The heating wire is used to heat the inner tube to ensure the temperature of the gas passing through the heating tube, so as to prevent the atomized water mist from condensing into condensate droplets during the flow process. The heating temperature of the heating tube does not exceed 40 degrees Celsius.

[0050] In some embodiments, the vent pipe 300 includes a first pipe section 313, a second pipe section 314, and a third pipe section 315 connected in sequence. The height of the second pipe section 314 is lower than that of the first pipe section 313 and the third pipe section 315. The second pipe section 314 is sealed to the side of the atomizing plate 220 where the mist outlet 222 is provided. A drain outlet is provided at the bottom of the second pipe section 314.

[0051] Specifically, the connecting pipe section 310 includes a first pipe section 313, a second pipe section 314, and a third pipe section 315 connected in sequence. The height of the second pipe section 314 is lower than that of the first pipe section 313 and the third pipe section 315. The end of the first pipe section 313 furthest from the second pipe section 314 is connected to the heating pipe section 320. That is, the first pipe section 313, the second pipe section 314, and the third pipe section 315 are connected in sequence to form a U-shaped pipe. When the ambient temperature is low (such as in winter), the temperature inside the vent pipe 300 cannot reach the target temperature, causing condensation to form inside the vent pipe 300. At this time, because the second pipe section 314 is the lowest, the condensate will concentrate and flow into the second pipe section 314, and be discharged from the drain port. This effectively reduces the air resistance of the vent pipe 300 and reduces the impact on the ventilation effect. Of course, when the water tank 100 leaks or the heating function of the heating element 210 fails, the condensate can also be discharged through the U-shaped connecting pipe section 310.

[0052] Furthermore, the inner wall of the second pipe section 314 is inclined, and the drain outlet is located at the lowest point of the inclined inner wall, so that the condensate can flow to the drain outlet under the action of gravity. Specifically, the drain outlet is located in the middle of the second pipe section 314, and the inner walls at both ends of the second pipe section 314 are relatively high, while the inner wall in the middle is relatively low.

[0053] Furthermore, the drain outlet is equipped with a float 330. When the condensate accumulates to a certain height, the buoyancy of the water will cause the float 330 to float up, thereby allowing the condensate to be discharged from the drain outlet.

[0054] In some other embodiments, the first pipe section 313 is inclined, that is, the end of the first pipe section 313 near the heating tube is higher than the end of the first pipe section 313 near the second pipe section 314, so that the condensate in the first pipe section 313 can also flow into the second pipe section 314.

[0055] In other embodiments, the connecting pipe section 310 may also be a V-shaped structure or an arc-shaped structure, with the drain outlet located at the lowest position of the connecting pipe section 310.

[0056] In some embodiments, the atomizing humidification device includes a controller 420, which is disposed on the outer wall of the water tank 100; a second temperature and humidity sensor 311 is disposed in the first pipe section 313, and a first temperature and humidity sensor 312 is disposed in the third pipe section 315; the controller 420 is electrically connected to the second temperature and humidity sensor 311, the first temperature and humidity sensor 312, and the atomizing heating module 200, respectively; the controller 420 is used to control the power of the atomizing heating module 200 according to the temperature and humidity detected by the first temperature and humidity sensor 312, and to adjust the power of the atomizing heating module 200 according to the temperature and humidity detected by the second temperature and humidity sensor 311.

[0057] Specifically, the controller 420 can be a control board PCBA. A first temperature and humidity sensor 312 is installed in the third pipe section 315 to detect the temperature and humidity of the air at the inlet of the ventilation pipe 300. A second temperature and humidity sensor 311 is installed in the first pipe section 313 to detect the temperature and humidity of the air at the outlet of the ventilation pipe 300. The controller 420 is electrically connected to the atomizing plate 220 and the heating plate 210 respectively. The controller 420 controls the power of the atomizing plate 220 and the heating plate 210 based on the temperature and humidity detected by the first temperature and humidity sensor 312 at the inlet of the ventilation pipe 300; and simultaneously detects the temperature and humidity at the outlet of the ventilation pipe 300 through the second temperature and humidity sensor 311, compares the temperature and humidity values ​​at the outlet of the ventilation pipe 300 with target values, and then adjusts the power of the atomizing plate 220 and the heating plate 210 accordingly.

[0058] Specifically, taking the controller 420 acquiring the values ​​of a first temperature and humidity sensor 312 and a second temperature and humidity sensor 311 per second as an example, the controller 420 first controls the power of the atomizing plate 220 and the heating plate 210 based on the temperature and humidity detected by the first temperature and humidity sensor 312 at the inlet of the ventilation pipe 300, so that the atomizing plate 220 and the heating plate 210 do work to change the temperature and humidity at the outlet of the ventilation pipe 300; then, it compares the temperature and humidity at the outlet of the ventilation pipe 300 detected by the second temperature and humidity sensor 311 with the target value. If the temperature and humidity value at the outlet of the ventilation pipe 300 is greater than the target value, the power of the atomizing plate 220 and the heating plate 210 is reduced; if the temperature and humidity value at the outlet of the ventilation pipe 300 is equal to the target value, the power of the atomizing plate 220 and the heating plate 210 remains unchanged; if the temperature and humidity value at the outlet of the ventilation pipe 300 is less than the target value, the power of the atomizing plate 220 and the heating plate 210 is increased.

[0059] Furthermore, in combination Figure 1 and Figure 4The atomizing humidifier includes a display screen 410, which is electrically connected to the controller 420. The display screen 410 is equipped with a temperature button and a humidity button.

[0060] The second temperature and humidity sensor 311 detects the temperature and humidity of the gas in the ventilation tube 300, processes the data, and displays it on the display screen 410 so that medical staff can monitor the temperature and humidity of the gas entering the patient's airway at any time. Furthermore, medical staff can set specific temperature and humidity values ​​on the display screen 410, and the controller 420 adjusts the power of the heating element 210 or the connecting tube 310 according to the set temperature value to ensure that the temperature of the gas in the ventilation tube 300 reaches the set temperature; similarly, the controller 420 can also adjust the power of the nebulizer 220 according to the set humidity value to ensure that the humidity of the gas in the ventilation tube 300 reaches the set humidity.

[0061] In some embodiments, a liquid level sensor 500 is provided in the water tank 100; the atomizing humidification device includes an alarm 430, and a controller 420 is electrically connected to the liquid level sensor 500 and the alarm 430 respectively. The controller 420 controls the alarm 430 to sound an alarm based on the liquid level information detected by the liquid level sensor 500.

[0062] In this embodiment, after the liquid in the water tank 100 is atomized, the liquid level gradually decreases. When the liquid level drops to a preset minimum level, the alarm 430 sounds, reminding medical staff to add liquid, or the controller 420 controls the ventilator to shut down. The alarm 430 may sound in various forms, including but not limited to using a speaker, a light, a video display, or both.

[0063] Furthermore, in combination Figure 2 and Figure 3 The liquid level sensor 500 includes a Hall sensor 510, a limiting post 520, and a float 530. The Hall sensor 510 is disposed at the bottom of the water tank 100, the limiting post 520 is disposed inside the water tank 100, the limiting post 520 has a hollow cavity communicating with the water tank 100, the limiting post 520 extends in a vertical direction, and the float 530 is movably disposed in the hollow cavity. The density of the float 530 is less than the density of the liquid.

[0064] In this embodiment, the Hall sensor 510 is disposed on the outer side of the bottom wall of the water tank 100, and a permanent magnet is disposed on the float 530. The limiting post 520 is fixed vertically inside the water tank 100, and the hollow cavity inside the limiting post 520 is connected to the water tank 100, that is, water in the water tank 100 can enter into the limiting post 520. Since the density of the float 530 is less than the density of the liquid, the float 530 can float on the liquid. When the liquid level drops, the float 530 can drop synchronously in the hollow cavity. When the float 530 drops to a certain height, it can be detected by the Hall sensor 510, thereby triggering the alarm 430 to prevent damage to the components of the atomizing heating module 200 when there is a lack of water.

[0065] Specifically, the limiting post 520 is a hollow cylindrical structure, located on the inner bottom of the housing 110, with its axis aligned with the axis of the Hall sensor 510. The closed design of the limiting post 520 restricts the float 530's movement to within its enclosure. A water inlet hole, smaller in diameter than the float 530, is provided at the bottom of the limiting post 520, allowing water from the tank 100 to enter the limiting post 520, but preventing the float 530 from moving outside the limiting post 520.

[0066] In other embodiments, the liquid level sensor 500 may also be a capacitive liquid level sensor 500, an ultrasonic liquid level sensor 500, a piezoelectric liquid level sensor 500, a conductive liquid level sensor 500, or a radar liquid level sensor 500. The liquid level sensor 500 is used to detect the lowest liquid level in the water tank 100 or to detect the liquid level in real time.

[0067] Specifically, the display screen 410 is installed on the outside of the side wall of the water tank 100, the controller 420 is electrically connected to the water tank 100, and the alarm 430 is installed on the display screen 410.

[0068] In some embodiments, the atomizing heating module 200 includes an atomizing sheet cover plate 230, with a placement cavity in the middle of the atomizing sheet cover plate 230, into which the atomizing sheet 220 is embedded. One side of the atomizing sheet cover plate 230 is sealed to the heating sheet 210, and the other side of the atomizing sheet cover plate 230 is sealed to the vent pipe 300.

[0069] In this embodiment, the atomizing plate cover 230 is bonded, welded or screwed to the heating plate 210.

[0070] Specifically, the atomizing heating module 200 includes a sealing gasket 240, and the other side of the atomizing plate cover 230 is sealed to the vent pipe 300 through the sealing gasket 240.

[0071] A flange is provided on the vent pipe 300, and the atomizing plate cover 230 is connected to the flange by screws. A sealing gasket 240 is provided between the cover and the flange to achieve a sealed connection between the atomizing plate cover 230 and the flange.

[0072] In some embodiments, the water tank 100 includes a tank body 110 and a tank cover 120, the tank cover 120 being detachably mounted on the tank body 110.

[0073] In this embodiment, a detachable cover 120 is used, which makes it easy to add water to the water tank 100 or clean the inside after removing the cover 120.

[0074] One embodiment of this application also provides a control method for an atomizing humidification device. The atomizing humidification device includes a controller 420, a second temperature and humidity sensor 311 is provided at the outlet of the air duct 300, and a first temperature and humidity sensor 312 is provided at the inlet of the air duct 300. The controller 420 is electrically connected to the second temperature and humidity sensor 311, the first temperature and humidity sensor 312, and the atomizing heating module 200. The control method includes the following steps: the controller 420 controls the power of the atomizing heating module 200 according to the temperature and humidity at the outlet of the air duct 300 detected by the first temperature and humidity sensor 312, and adjusts the power of the atomizing heating module 200 according to the temperature and humidity at the inlet of the air duct 300 detected by the second temperature and humidity sensor 311. That is, by using the detection of the second temperature and humidity sensor 311 and the first temperature and humidity sensor 312, it is convenient to adjust the power of the atomizing heating module 200 in real time according to the detection results, thereby reducing power consumption.

[0075] Combination Figure 2 An embodiment of this application also provides a ventilator, including a ventilator body 620, a breathing mask 610, and a nebulizing humidifier. One end of the ventilation tube 300 is connected to the breathing mask 610, and the other end is connected to the ventilator body 620.

[0076] In this embodiment, one end of the ventilation tube 300 is connected to the ventilator body 620, and the other end is connected to the breathing mask 610. The water tank 100 is connected to the ventilation tube 300 between the ventilator body 620 and the breathing mask 610. Water mist of a certain temperature generated in the water tank 100 enters the ventilation tube 300. When the gas in the ventilator body 620 flows, it can carry the water mist, thereby providing the patient with gas that meets certain temperature and humidity requirements.

[0077] In actual use, the ventilator blows air into the ventilation tube 300. Medical staff set the nebulization power of the nebulizer 220 and the target temperature and humidity of the heating element 210 on the display screen 410. The nebulizer 220 and the heating element 210 start to work to blow out a certain amount of heated water mist. When the airflow from the ventilator passes under the nebulizer 220, it will carry away the water mist at the same time, forming humidified gas that meets the temperature and humidity settings. After the humidified gas enters the connecting tube section 310, it will flow into the heating tube section 320 to maintain the temperature and prevent the formation of condensate. Finally, the humidified gas is delivered into the patient's airway.

[0078] Furthermore, after prolonged atomization, the water level in the water tank 100 will gradually decrease. When the water level drops to the position of the float 530, the float 530 will descend simultaneously with the water level. When the float 530 descends into the sensing range of the Hall sensor 510, the Hall sensor 510 will be triggered. When the Hall sensor 510 is triggered, the controller 420 will issue a command to stop the atomizing plate 220 and the heating plate 210 from working, thereby effectively preventing damage to the atomizing plate 220; at the same time, the controller 420 will control the speaker to emit an audible alarm and display a visual alarm on the display screen 410 to remind the user to add water to the water tank.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
