Description

Technical Field

[0001] This invention relates to the field of respiratory nebulization devices, specifically a nebulization device for elderly respiratory patients. Background Technology

[0002] Nebulization therapy mainly refers to aerosol inhalation therapy. Aerosols are tiny solid or liquid particles suspended in the air. Therefore, nebulization therapy uses a nebulizer to disperse medication into tiny droplets or particles, suspending them in the gas and allowing them to enter the respiratory tract and lungs. This achieves the goals of cleaning and humidifying the airways, providing local and systemic treatment. Nebulization therapy is an important and effective treatment method for respiratory diseases. By using a nebulizer to atomize liquid medication into tiny particles, the medication enters the respiratory tract and lungs through inhalation, thereby achieving painless, rapid, and effective treatment.

[0003] When using current nebulizers for elderly respiratory patients, a small amount of medication often sticks to the side wall of the nebulizer head and settles at the bottom during the final stage of nebulization, resulting in wasted medication and reduced utilization. Furthermore, due to the deep interior of the nebulizer cartridge, elderly patients often find it difficult to effectively dry the inside after manually rinsing and wiping, leading to medication or rinsing water residue. This residue, if left inside the cartridge for an extended period, can contaminate the next use and potentially cause secondary harm to elderly patients. Additionally, elderly patients are prone to inhaling cold mist during nebulization, which can irritate the respiratory tract and cause discomfort.

[0004] To address the above issues, a nebulizer for elderly respiratory patients is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a nebulizer for elderly respiratory patients. By using this device, the problems mentioned above can be solved, such as the adhesion or settling of the nebulized medication, which easily leads to the waste of some medication and a decrease in the utilization rate of the medication. Furthermore, it is difficult to effectively dry the inside of the nebulizer cylinder, resulting in residual medication or rinsing water, which may contaminate new medication and cause secondary harm to elderly patients.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a nebulization device for elderly respiratory patients, comprising a ventilator and a connecting trachea connected above the ventilator, an outer nebulizer cylinder connected above the connecting trachea, and a nebulizing nozzle fixed inside the lower part of the outer nebulizer cylinder, the output end of the connecting trachea being connected to the nebulizing nozzle, an inner nebulizer cylinder installed at the upper part of the inner nebulizer cylinder, and connecting rods fixed at the lower sides of the inner nebulizer cylinder, a nozzle cover fixed at the lower center of the inner nebulizer cylinder, a liquid collection base plate fixed outside the nebulizer nozzle, an air outlet pipe connected above one side of the outer nebulizer cylinder, and a breathing mask installed outside the air outlet pipe, and a one-way air inlet installed at the top of the inner nebulizer cylinder; A switching mechanism is connected below the atomizing nozzle, a sliding mechanism is provided on the outer side of the liquid collecting base plate, a heat insulation mechanism is sleeved on the outside of the atomizing outer cylinder, and a protective mechanism is installed in the middle of the inner side of the atomizing inner cylinder.

A sealing plug is slidably disposed in the middle of one side of the air inlet seat. A push rod is fixed to one side of the sealing plug, and a spring is disposed on the outside of one end of the push rod. The two ends of the spring are respectively fixed to the sealing plug and the air inlet seat.

[0011] Furthermore, a gas distribution pipe is connected to the middle of the other side of the gas receiving seat, and a one-way valve is installed in the middle of the gas distribution pipe. A vent pipe is connected above one side of the one-way valve, and a gas distribution ring is connected to the upper output end of the vent pipe. The gas distribution ring is located on the outside of the liquid collecting base plate, and several air jets are arranged in a ring on the inner surface of the gas distribution ring.

[0012] Furthermore, a shield is fixed in a ring at the upper center of the fixed cover, and a vent is provided inside the lower part of the shield. Several groups of vents are arranged in a ring around the fixed cover, and an expansion piece is fixed inside each group of vents.

[0013] Furthermore, the heat preservation mechanism includes a sleeve fitted over the outer atomizing cylinder, with clearance grooves on both sides of the sleeve, a liquid inlet on one side of the sleeve, and a cap plug installed on the outside of the liquid inlet, and a water storage chamber inside the sleeve.

[0014] Furthermore, a conduit is provided on the upper side of one side of the package sleeve, and the conduit is connected to the water storage cavity. A plug is connected to the top of the conduit. A second conduit is fixed on the upper side of one side of the atomizing outer cylinder. A fitting opening is provided on the upper surface of the atomizing inner cylinder, and a water guiding cavity is provided inside the atomizing inner cylinder. A waterproof and breathable hole is provided on one side of the water guiding cavity.

[0015] Furthermore, the protective mechanism includes a temperature-conducting seat fixed inside the atomizing inner cylinder, a shape memory metal is fixed to the upper inner end of the temperature-conducting seat, and a sliding rod is fixed to the bottom of the shape memory metal, and the sliding rod is slidably connected to the temperature-conducting seat, and a shielding head is fixed to the bottom of the sliding rod. The inner side of the memory metal one is provided with memory metal two, and the bottom of memory metal two is fixedly connected to the top surface of the sliding rod. The top of the memory metal two is fixed with an abutment plate, and the lower center of the abutment plate is fixed with a fixed sliding rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention can block the liquid in the collection plate to prevent the liquid from flowing freely. When elderly respiratory patients use it, they can adjust the nebulizer cylinder to any angle without worrying about the liquid spilling or being lost. This avoids the problem of the elderly patient having to use the nebulizer cylinder vertically to prevent the liquid from spilling, making nebulization more convenient and comfortable for the elderly patient.

[0017] 2. This invention can recycle residual medication for secondary atomization, thereby maximizing the utilization of the medication and reducing waste. At the same time, it can thoroughly dry both the outer and inner atomizing cylinders from bottom to top, thus avoiding the problem of residual medication or rinsing water contaminating new medication for the next use. This helps maintain hygiene for long-term use of the atomizer and avoids secondary harm to elderly patients.

[0018] 3. This invention allows the liquid medicine to form a warm mist that can be inhaled by the patient, avoiding the stimulation of the respiratory mucosa by cold mist. It is especially suitable for elderly patients with asthma, chronic bronchitis, etc., reducing discomfort such as coughing and chest tightness during nebulization, improving the therapeutic effect and comfort. At the same time, it relies on warm water for preheating, allowing patients to adjust the water temperature according to their own needs. It is also relatively simple and safe to operate.

[0019] 4. During the atomization process, if the temperature of the medicine gradually drops below 33 degrees Celsius due to the decrease in water temperature of the heat preservation mechanism, the shape memory metal progressive contraction can slowly adjust the position of the shield, gradually reducing the spray intensity, avoiding choking or discomfort caused by sudden temperature changes and sudden activation of the protection, improving the smoothness of the experience, and the blocking and buffering protection against hot and cold medicine can improve the comfort and safety of elderly patients during atomization, thereby improving the effectiveness of the device for elderly patients.

[0020] 5. If the temperature gradually drops below 33 degrees Celsius after preheating, the present invention can trigger feedback in a timely manner, so as to avoid the patient not noticing the abnormal temperature during nebulization, thereby improving the operational error tolerance rate. Moreover, elderly patients do not need to manually monitor the temperature or adjust the parameters. They only need to perform simple operations according to the prompts, such as adding warm water or pausing nebulization. This is suitable for the characteristics of elderly patients with weaker operation ability and improves the ease of use of the device. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] To address the technical problem of medication leakage during nebulization due to limited mobility and difficulty in controlling body position, such as... Figures 1-4 As shown, the following preferred technical solutions are provided: A nebulizer for elderly respiratory patients includes a ventilator 1 and a connecting tube 2 connected to the top of the ventilator 1. The ventilator 1 is the control part of an existing nebulizer, and its function is to provide a stable airflow for the nebulization process, control the nebulization parameters, and ensure the safe operation of the device. It also has a built-in compressor that can compress air into a high-pressure airflow, which is delivered through the connecting tube 2. The specific principle of the existing ventilator 1 will not be elaborated here. An outer nebulizer cylinder 3 is connected to the top of the connecting tube 2, and a nebulizer nozzle 4 is fixed inside the lower part of the outer nebulizer cylinder 3. The output end of the connecting tube 2 is connected to the nebulizer nozzle 4, and the airflow delivered in the connecting tube 2 can be sprayed out from the nebulizer nozzle 4. An inner nebulizer cylinder 5 is installed at the upper part of the inner nebulizer cylinder 3, and plug-in rods 50 are fixed on both sides of the lower part of the inner nebulizer cylinder 5. The inner nebulizer cylinder 5 is tightly inserted into the outer nebulizer cylinder 3 using the plug-in rods 50 to facilitate the assembly and disassembly of the inner nebulizer cylinder 5 and the outer nebulizer cylinder 3.

[0025] Furthermore, a nozzle cover 6 is fixed to the lower center of the atomizing inner cylinder 5, and a liquid collecting base plate 7 is fixed to the outside of the atomizing nozzle 4, such as... Figure 5 As shown, when the atomizing inner cylinder 5 is not installed with the atomizing outer cylinder 3, the atomized medicine can be added into the atomizing outer cylinder 3, so that the medicine is concentrated above the liquid collection base plate 7. After the medicine is added, the atomizing inner cylinder 5 is inserted and installed. At this time, the nozzle cover 6 will cover the outside of the atomizing nozzle 4. The inner diameter of the nozzle cover 6 is slightly larger than the outer diameter of the atomizing nozzle 4, so that there is a gap between the atomizing nozzle 4 and the nozzle cover 6. When the air is sprayed into the atomizing nozzle 4, under the action of air pressure, the medicine on the liquid collection base plate 7 will flow to the top of the atomizing nozzle 4 through the gap, so that the medicine is broken into micron-sized droplets under the impact of the airflow, forming an inhalable aerosol, which diffuses inside and above the atomizing outer cylinder 3.

[0026] An air outlet tube 30 is connected to the upper side of one side of the nebulizer outer cylinder 3, and a breathing mask 40 is installed on the outside of the air outlet tube 30. When the patient wears the breathing mask 40, the drug liquid aerosol in the nebulizer outer cylinder 3 will enter the patient's body through the air outlet tube 30 for nebulization treatment. A one-way air port 60 is installed at the top of the nebulizer inner cylinder 5. The one-way air port 60 is a one-way exhaust port, so that the patient can breathe smoothly after wearing the breathing mask 40. A switching mechanism 8 is connected to the bottom of the nebulizer nozzle 4, and a sliding mechanism 9 is provided on the outer side of the upper part of the liquid collection base plate 7. When the inner nebulizer cylinder 5 and the outer nebulizer cylinder 3 are installed after the medication is added, so that the nozzle cover 6 is installed and covers the outside of the nebulizer nozzle 4, the middle extension of the nozzle cover 6 will coincide with the extension of the sliding mechanism 9. After the two extensions coincide, a sealed cover plate will be formed above the liquid collection base plate 7. At this time, the medication on the liquid collection base plate 7 can be blocked to prevent the medication from flowing randomly. Therefore, when elderly respiratory patients use it, the outer nebulizer cylinder 3 can be adjusted to any angle without worrying about the medication spilling or being lost. This avoids the problem of the elderly patient's body position restriction when using the outer nebulizer cylinder 3 vertically to prevent the medication from spilling, making nebulization more convenient and comfortable for the elderly patient.

[0027] When atomization reaches its final stage or the medication is almost used up, a small amount of medication often sticks to the side wall of the atomizing outer cylinder 3 and settles at the bottom of the collection plate 7, failing to atomize and resulting in waste of some medication and reduced utilization. Furthermore, because the atomizing outer cylinder 3 is relatively deep, elderly patients often find it difficult to effectively dry the inside after manually rinsing and wiping it, leading to residues of medication or rinsing water. These residues, if left inside the cavity for a long time, may contaminate the new medication and potentially cause secondary harm to elderly patients. Therefore, when atomization reaches its final stage or the medication is almost used up, the sliding mechanism 9 can be slid up and down repeatedly. This allows the sliding mechanism 9, located inside the atomizing outer cylinder 3, to move up and down along the inner wall of the atomizing outer cylinder 3, scraping the medication stuck to the side wall downwards and allowing it to fall back onto the collection plate 7.

[0028] Then, pressing the switching mechanism 8 allows some airflow to enter the interior of the liquid collection base plate 7, enabling the airflow to blow from the outside to the inside of the liquid collection base plate 7. Since there is a gap between the nozzle cover 6 and the atomizing nozzle 4, the inward blowing of the airflow can carry the liquid medicine that has settled at the bottom of the liquid collection base plate 7 and the scraped-off liquid medicine into the gap and make it flow upward. At this time, in conjunction with the airflow sprayed from the atomizing nozzle 4, the residual liquid medicine can be atomized, thereby maximizing the utilization of the liquid medicine and reducing the waste of residual liquid medicine.

[0029] Simultaneously, after rinsing the outer atomizing cylinder 3 and the inner atomizing cylinder 5, they can be reinstalled. The outer atomizing cylinder 3 can then be reconnected to the connecting air pipe 2 for ventilation. The sliding mechanism 9 is then slid upwards, separating it from the nozzle cover 6, opening the top of the liquid collecting base plate 7 and allowing airflow upwards. Since the atomizing nozzle 4 is a single-point jet nozzle and extends into the middle of the outer atomizing cylinder 3, using the jet nozzle 4 for drying would result in uneven airflow diffusion and ineffective drying. At this point, the switching mechanism 8 is pressed again, allowing some airflow to be sprayed again from inside the liquid collecting base plate 7. When the liquid is discharged, the airflow will spread evenly upward from the bottom of the liquid collection plate 7 and finally flow out from the air outlet pipe 30. Under the action of the airflow, the outer atomizing cylinder 3 and the inner atomizing cylinder 5 can be thoroughly dried from bottom to top. This avoids the problem of residual medicine or rinsing water, which may contaminate the new medicine for the next use. It is beneficial to maintain the hygiene of the atomizer for long-term use and avoid secondary harm to elderly patients. At the same time, the above effects can be achieved by simply moving the sliding mechanism 9 up and down and pressing the switching mechanism 8 when the medicine is recovered and dried. There is no need for complicated operation, which makes it more suitable for use by elderly patients.

[0030] An insulation mechanism 10 is fitted around the outer atomizing cylinder 3. Before atomization, after the outer atomizing cylinder 3 and the inner atomizing cylinder 5 are installed, warm water can be filled into the insulation mechanism 10. Then, the insulation mechanism 10 is fitted onto the outside of the outer atomizing cylinder 3. Once fitted, the insulation mechanism 10 connects with the water channels on the outer atomizing cylinder 3 and the inner atomizing cylinder 5. Then, the outer atomizing cylinder 3 is flipped so that the inner atomizing cylinder 5 faces downwards. At this time, the warm water in the insulation mechanism 10 will flow into the interlayer inside the inner atomizing cylinder 5 through the water channels under the action of gravity. Then, the outer atomizing cylinder 3 is flipped back to its original position. At this time, the insulation mechanism 10 and the inner atomizing cylinder 5... The inner interlayer contains warm water, which preheats the medication in the outer nebulizer cylinder 3 before and during nebulization, forming a warm mist that is inhaled by the patient. This avoids cold mist irritating the respiratory mucosa, making it especially suitable for elderly patients with asthma, chronic bronchitis, etc. It reduces discomfort such as coughing and chest tightness during nebulization, improving treatment effectiveness and comfort. The preheating is achieved using insulated water, allowing patients to adjust the water temperature according to their needs. It is also relatively simple and safe to operate, avoiding the safety hazards of using generator-generated heating, which is difficult for the elderly to operate.

[0031] A protective mechanism 20 is installed in the middle of the inner side of the nebulizer cylinder 5. The protective mechanism 20 is equipped with a temperature memory alloy, which can identify the temperature inside the nebulizer cylinder 5 during preheating. When the preheating temperature is too high and exceeds body temperature, the protective mechanism 20 can extend to approach the top of the nebulizer nozzle 4, so that the spray can be blocked and buffered by the protective mechanism 20 and weakened, thereby avoiding discomfort caused by elderly patients inhaling a large amount of high-temperature nebulized medicine at one time, and ensuring safety after preheating. At the same time, when the temperature inside the nebulizer cylinder 5 returns to below body temperature, the protective mechanism 20 retracts and resets to perform normal nebulization treatment.

[0032] The nozzle cover 6 includes a fixed cover 61 located outside the atomizing inner cylinder 5. The fixed cover 61 is fixedly connected to the nozzle cover 6. The outer side of the fixed cover 61 is provided with several protruding edges 62. The fixed cover 61 is inclined, which facilitates the downward flow of the liquid during subsequent liquid recovery. Furthermore, there are mating grooves 63 between the protruding edges 62.

[0033] The sliding mechanism 9 includes a support ring 91 fixed to the inner wall of the atomizing outer cylinder 3, and a fitting slip ring 92 is provided above the support ring 91. The fitting slip ring 92 is tightly fitted to the inner wall of the atomizing outer cylinder 3. The support ring 91 can limit and support the fitting slip ring 92. Several protruding edges 93 are fixedly fixed on the inner side of the fitting slip ring 92. When the atomizing inner cylinder 5 and the atomizing outer cylinder 3 are installed after the dosing, so that the nozzle cover 6 is installed and covers the outside of the atomizing nozzle 4, the fitting slip ring 92 will be fitted into the mating groove 63, so that the fitting slip ring 92 is fitted into the groove 63. Ring 92, convex edge 2 93, convex edge 1 62, and fixing cover 61 form a sealed cover above the liquid collecting base plate 7. This can block the liquid on the liquid collecting base plate 7, thereby preventing the liquid from flowing freely. When elderly respiratory patients use it, the nebulizer outer cylinder 3 can be adjusted to any angle without worrying about the liquid spilling or being lost. This avoids the discomfort caused by elderly patients using the nebulizer outer cylinder 3 vertically for a long time to prevent the liquid from spilling, making nebulization more convenient and comfortable for elderly patients.

[0034] To address the technical issues of medication sticking or settling after nebulization, which easily leads to waste and reduced utilization, and the difficulty in effectively drying the nebulizer cartridge, resulting in residual medication or rinsing water that could contaminate new medication and potentially cause secondary harm to elderly patients, [further solutions are needed]. Figures 1-7 As shown, the following preferred technical solutions are provided: A magnet 94 is fixed to the inner center of the slip ring 92. Limiting grooves 95 are respectively formed on both sides of the surface of the atomizing outer cylinder 3, and sliders 96 are slidably arranged inside each limiting groove 95. The limiting grooves 95 can limit the sliders 96 to prevent misalignment during subsequent movement. Slide plates 97 are fixed to the outer sides of each slider 96, and magnets 98 are fixed inside each slide plate 97. A protrusion 99 is fixed to one side of the surface of the atomizing outer cylinder 3. The protrusion 99 is arc-shaped and semi-circular, made of rubber, allowing for easy deformation and better engagement with the sliders 96. The sliders 96 and protrusion 99 engage with each other. Magnets 98 and 94 have opposite magnetic properties, allowing the slide plates 97 to be magnetically attracted and adhered to the outer surface of the atomizing outer cylinder 3. The slip ring 92 is fitted with protrusions 93 and 62. When the slide plate 97 and slider 96 engage with the protrusion 99, it can prevent the slip ring 92 from sliding freely, thus ensuring the stable engagement of the slip ring 92 and the protrusion 62 and preventing liquid leakage. When the atomization reaches the end stage or the liquid is used up, the slide plate 97 and slider 96 can slide up and down along the limiting groove 95, so that the slip ring 92 and the protrusion 62 can be separated from the protrusion 62 under the magnetic attraction of the magnet 98 and the magnet 94, and move up and down along the inner wall of the atomizing outer cylinder 3 to scrape the inner wall of the atomizing outer cylinder 3. This allows the slip ring 92 to scrape the liquid stuck to the side wall of the atomizing outer cylinder 3 downwards, so that the liquid falls back onto the liquid collection base plate 7. The upper end face of the slip ring 92 is inclined, which facilitates the sliding of the droplets when it moves upwards to scrape the liquid.

[0035] The switching mechanism 8 includes an air inlet seat 81 connected to the bottom of the atomizing nozzle 4, and the bottom of the air inlet seat 81 is connected to the connecting air pipe 2. A sealing plug 82 is slidably disposed in the middle of one side of the air inlet seat 81. The side wall of the sealing plug 82 is tightly fitted with the side wall of the air inlet seat 81 to prevent gas leakage. A push rod 83 is fixed to one side of the sealing plug 82. The push rod 83 slides through the atomizing outer cylinder 3, and a spring 84 is disposed on the outside of one end of the push rod 83. The two ends of the spring 84 are fixed to the sealing plug 82 and the air inlet seat 81, respectively. Pressing the push rod 83 and the sealing plug 82 can stretch the spring 84. The maximum movement distance of the sealing plug 82 does not contact the side wall of the air inlet seat 81. Releasing the push rod 83 can reset the push rod 83 and the sealing plug 82 under the retraction of the spring 84.

[0036] A gas distribution pipe 85 is connected to the middle of the other side of the gas receiving seat 81, and a one-way valve 86 is installed in the middle of the gas distribution pipe 85. The one-way valve 86 is a one-way exhaust valve. A vent pipe 87 is connected to the upper side of the one-way valve 86, and a gas distribution ring 88 is connected to the upper output end of the vent pipe 87. The gas distribution ring 88 is located on the outer side of the liquid collecting base plate 7, and several air jets 89 are arranged in a ring on the inner surface of the gas distribution ring 88. An expansion diaphragm is provided at the outlet end of the air jet 89, which expands and opens only under the action of air pressure, thereby preventing the liquid medicine in the liquid collecting base plate 7 from flowing into the gas distribution ring 88. After the sliding ring 92 scrapes the liquid medicine stuck to the side wall of the atomizing outer cylinder 3 downward, the push rod 83 and the sealing plug 82 are pressed to move the sealing plug 82 and narrow the air passage of the gas receiving seat 81. At this time, the gas receiving seat 81 The internal air pressure will increase, which will open the one-way valve 86, allowing some airflow to enter the air distribution ring 88 through the air distribution pipe 85 and the air vent 87. This allows the airflow to be blown out from the jet nozzle 89 to the inside of the liquid collection base plate 7. Since there is a gap between the nozzle cover 6 and the atomizing nozzle 4, the inward blowing of the airflow can carry the liquid medicine that has settled at the bottom of the liquid collection base plate 7 and the scraped-down and recovered liquid medicine to the gap between the nozzle cover 6 and the atomizing nozzle 4 and make it flow upward. At this time, in conjunction with the airflow sprayed from the atomizing nozzle 4, the residual liquid medicine can be atomized. By utilizing the synergistic effect of wall scraping and airflow recovery, the utilization of the liquid medicine can be maximized and the waste of residual liquid medicine can be reduced. When the liquid medicine treatment is used up, the machine can be stopped for further treatment.

[0037] Simultaneously, after rinsing the atomizing outer cylinder 3 and the atomizing inner cylinder 5, the atomizing outer cylinder 3 and the atomizing inner cylinder 5 can be reinstalled, allowing the air inlet seat 81 to reconnect to the connecting air pipe 2 for ventilation. Then, slide the sliding plate 97 and the fitting slip ring 92 upwards, causing the second protrusion 93 to separate from the first protrusion 62, opening the top of the liquid collecting base plate 7 and allowing the airflow to flow upwards. At this time, press the push rod 83 and the sealing plug 82 again, allowing some airflow to be ejected again from the jet nozzle 89. The airflow will then diffuse evenly upwards from the bottom surface of the liquid collecting base plate 7, eventually exiting from the air outlet pipe. The airflow from the 30 outlet allows for thorough drying of both the outer atomizing cylinder 3 and the inner atomizing cylinder 5 from bottom to top. This prevents residual medication or rinsing water from contaminating the new medication during subsequent use, ensuring hygiene for long-term atomization and preventing secondary harm to elderly patients. Furthermore, medication recovery and drying can be achieved simply by moving the slide plate 97 up and down and pressing the push rod 83, eliminating the need for complicated procedures and making it more suitable for elderly patients.

[0038] A shielding cover 66 is fixed in a ring at the upper center of the fixed cover 61. A vent 64 is provided inside the lower part of the shielding cover 66, and several groups of vent 64 are arranged in a ring around the fixed cover 61. An expansion piece 65 is fixed inside the vent 64. When the residual medicine is blown into the liquid collection base plate 7, the second protrusion 93 and the first protrusion 62 are in an engaged state. At this time, under the action of air pressure, the rubber expansion piece 65 will be forced open, so that the airflow can pass out from the vent 64. The airflow will be guided by the shielding cover 66 and blow from top to bottom from the outer surface of the fixed cover 61. Then the slip ring 92 moves up, so that the fixed cover 61 and the slip ring 92 are separated. This allows the medicine on the surface of the fixed cover 61 to fall into the liquid collection base plate 7, thereby further reducing the retention of medicine and improving the utilization rate of medicine.

[0039] To address the technical issue that elderly users may inhale cold or hot mist during nebulization, which can irritate their respiratory tract and cause discomfort, such as... Figure 1 , Figure 2 as well as Figures 8-11 As shown, the following preferred technical solutions are provided: The heat preservation mechanism 10 includes a cover 101 that is fitted over the atomizing outer cylinder 3. The cover 101 has clearance grooves 102 on both sides. The clearance grooves 102 can prevent the vent pipe 87, the limiting slide groove 95 and the slide plate 97 on the surface of the atomizing outer cylinder 3 from being blocked. A liquid filling port 103 is opened on the upper side of one side of the cover 101. A capping plug 104 is installed on the outside of the liquid filling port 103. A water storage chamber 105 is provided inside the cover 101. When not atomizing, warm water can be filled into the water storage chamber 105 inside the cover 101 through the liquid filling port 103, and then the capping plug 104 is plugged in to seal it. Then the cover 101 is fitted over the outside of the atomizing outer cylinder 3.

[0040] A conduit 106 is provided on one side of the outer sleeve 101, and the conduit 106 is connected to the water storage chamber 105. The top of the conduit 106 is connected to the plug 107. A conduit 2 108 is fixed on one side of the outer atomizing cylinder 3. The conduit 2 108 is fixed to the outer atomizing cylinder 3. Both the conduit 2 108 and the conduit 106 are rigid tubes, and both ends of the conduit 2 108 are connected. A fitting opening 109 is provided on the surface of the inner atomizing cylinder 5, and a water guiding cavity 110 is provided inside the inner atomizing cylinder 5. A waterproof and breathable hole 111 is provided on one side of the water guiding cavity 110, and a waterproof and breathable membrane is provided inside the waterproof and breathable hole 111. It can vent air when water is filled in the water guiding cavity 110 without causing water to flow out. A rubber ring is provided outside the fitting port 109. When the atomizing outer cylinder 3 and the atomizing inner cylinder 5 are installed, the fitting port 109 will be sealed and fitted with the upper outlet of the second conduit 108, so that the second conduit 108 can communicate with the water guiding cavity 110 without leakage. When the wrapping sleeve 101 is fitted outside the atomizing outer cylinder 3, the first conduit 106 will be connected to the bottom opening of the second conduit 108 through the plug 107, so that the second conduit 108 can communicate with the water storage cavity 105. The wrapping sleeve 101 is made of elastic rubber and has the ability to be deformed by compression.

[0041] After the outer sleeve 101 is connected, the outer nebulizer cylinder 3 is flipped so that the inner nebulizer cylinder 5 faces downwards. The outer sleeve 101 is then squeezed. At this time, some of the warm water in the water storage chamber 105 is forced into the water guiding chamber 110 through the first conduit 106 and the second conduit 108 under pressure. The outer nebulizer cylinder 3 is then flipped back to its original position. Now, both the water storage chamber 105 and the water guiding chamber 110 contain warm water. This preheats the medication in the outer nebulizer cylinder 3 before and during nebulization, forming a warm mist that is inhaled by the patient, preventing cold mist from irritating the respiratory mucosa, especially... Suitable for elderly patients with asthma, chronic bronchitis, etc., it reduces discomfort such as coughing and chest tightness during nebulization, improving the treatment effect and comfort. It relies on the warm water in the water storage chamber 105 and the water guide chamber 110 for preheating, allowing patients to adjust the water temperature according to their own needs. It is also relatively simple and safe to operate, avoiding the problem of using generator heating, which is difficult for the elderly to operate and may pose safety hazards. After nebulization, the water in the water storage chamber 105 and the water guide chamber 110 can be drained after removing the cover 101 and the inner cylinder 5.

[0042] The protective mechanism 20 includes a temperature-conducting seat 201 fixed inside the atomizing inner cylinder 5. The temperature-conducting seat 201 is made of a thermally conductive metal, which can improve the absorption and transfer of temperature. A shape memory metal 202 is fixed to the upper part of the interior of the temperature-conducting seat 201. The shape memory metal 202 is a stretchable, slow-deformation temperature memory alloy with a heat deformation temperature range of 40 degrees Celsius. When the temperature exceeds 40 degrees Celsius, it will expand and move. A sliding rod 203 is fixed to the bottom of the shape memory metal 202, and the sliding rod 203 is slidably connected to the temperature-conducting seat 201. A shielding head 204 is fixed to the bottom of the sliding rod 203. If the hot water added by the elderly is too hot, causing the preheating temperature inside the nebulizer cylinder 5 to exceed 40 degrees Celsius, the shape memory metal 202 can drive the sliding rod 203 and the shielding head 204 to extend, so that the shielding head 204 is close to the top of the nebulizer nozzle 4. This allows the spray to be buffered and weakened by the shielding head 204, thus preventing the elderly patient from inhaling a large amount of hot nebulized medicine at once and causing discomfort, ensuring safety after preheating. At the same time, when the temperature inside the nebulizer cylinder 5 returns to below 40 degrees Celsius, the shape memory metal 202 drives the shielding head 204 to retract and reset, so that normal nebulization treatment can be performed.

[0043] like Figure 11 As shown, a second shape memory metal 205 is provided inside the first shape memory metal 202. The second shape memory metal 205 is also a stretchable, slow-deformation temperature shape memory alloy. When the temperature is below 33 degrees Celsius, the second shape memory metal 205 will contract and move. The bottom of the second shape memory metal 205 is fixedly connected to the top surface of the sliding rod 203. A contact plate 206 is fixed to the top of the second shape memory metal 205, and a fixed sliding rod 207 is fixed to the lower center of the contact plate 206. The fixed sliding rod 207 is slidably connected to the sliding rod 203, and a baffle plate 208 is fixed to the bottom of the fixed sliding rod 207. The baffle plate 208 and the fixed sliding rod 207 form an inverted T-shaped structure. A pressure sensor 209 is attached to the top of the contact plate 206, and the pressure sensor 209 is fixed inside the temperature conducting seat 201. The pressure sensor 209 is electrically connected to the control circuit of the breathing host 1 based on the existing principle.

[0044] When the nebulizer inner cylinder 5 is preheated normally, and the temperature inside the nebulizer inner cylinder 5 is between 33-40 degrees Celsius, which is a comfortable range, normal nebulization can be performed. At this time, the shape memory metal 205 is in normal condition, and the baffle plate 208 is embedded in the baffle head 204. At the same time, the contact plate 206 will press against the pressure sensor 209. When the pressure sensor 209 is pressed, in conjunction with the existing control circuit in the breathing host 1, the existing indicator lights and the sound generator of the breathing host 1 will not work. When the preheating temperature inside the nebulizer inner cylinder 5 is too high... When the temperature exceeds 40 degrees Celsius, the shape memory metal 202 extends the sliding rod 203 and the blocking head 204, and simultaneously extends the shape memory metal 205, the contact plate 206, the fixed sliding rod 207 and the blocking plate 208. At this time, the contact plate 206 will separate from the pressure sensor 209, causing the pressure sensor 209 to lose pressure. The pressure sensor 209, in conjunction with the control circuit inside the ventilator 1, will cause the existing indicator lights of the ventilator 1 to flash continuously and the speaker to make a sound to provide a prompt, so that the patient can make adjustments to the nebulization.

[0045] If, after a period of preheating, the atomization temperature gradually drops below 33 degrees Celsius, the device will spray a cold mist. Elderly patients inhaling this cold mist may experience mild coughing or throat discomfort. When the temperature drops below 33 degrees Celsius, the shape of memory metal 202 returns to its original shape and remains stationary, while memory metal 205 contracts and moves. As memory metal 205 contracts, its bottom is fixed to the sliding rod 203, causing the top of memory metal 205 to move downwards and extend, along with the contact plate 206, the fixed sliding rod 207, and the baffle plate 208. This causes the baffle plate 208 to move downwards and approach the top of the atomizing nozzle 4, thus buffering and weakening the spray and preventing elderly patients from inhaling large amounts of cold mist medication at once. During nebulization, if the temperature of the medication gradually drops below 33 degrees Celsius due to a decrease in the water temperature of the insulation mechanism 10, the memory metal 205 gradually contracts to slowly adjust the position of the shield 208, gradually reducing the spray intensity. This avoids coughing or discomfort caused by sudden temperature changes and sudden activation of the shield, improving the smoothness of the experience. At the same time, the contact plate 206 moves down and separates from the pressure sensor 209, causing the existing indicator lights on the breathing unit 1 to flash continuously and the speaker to make a sound to provide prompts. This allows patients to make adjustments to the nebulization without the need for elderly patients to manually monitor the temperature or adjust parameters. They only need to perform simple operations according to the prompts, such as adding warm water or pausing nebulization. This is suitable for elderly patients with weaker operational abilities and improves the ease of use of the device.

[0046] Meanwhile, the deformation of the shape memory metal 205 allows for monitoring of temperature changes during nebulization. If the temperature gradually drops below 33 degrees Celsius after preheating, feedback can be triggered, preventing patients from going unnoticed due to temperature abnormalities during nebulization and improving operational error tolerance. If an elderly patient neglects to preheat with warm water or starts nebulization before the preheating temperature reaches 33 degrees Celsius, and the temperature inside the nebulizer cylinder 5 is below 33 degrees Celsius, the shape memory metal 205 will also be in a contracted state, causing the contact plate 206 to be in a downward blocking and protective state. Simultaneously, the breathing unit 1 will flash indicator lights and emit an audible prompt to remind the patient to perform preheating. The shape memory metal 205, through... The retraction causes the shield 208 to move downward, blocking the cold mist from irritating the respiratory tract. It can also extend synchronously with the memory metal 202 at high temperatures, working with the shield head 204 to enhance the buffering effect of the high-temperature mist, forming a two-way protection against both high and low temperatures. This is suitable for the temperature sensitivity of the respiratory tract of elderly patients. At the same time, the memory metal 202 and memory metal 205 are not affected by water when the device is washed after use, making them more suitable for high-frequency scenarios where the outer nebulizer 3 and the inner nebulizer 5 need to be washed and cleaned. This blocking and buffering protection against the hot and cold of the liquid improves the comfort and safety of elderly patients during nebulization, thereby improving the effectiveness of the device for elderly patients.
