Description

Technical Field

[0001] This invention relates to the field of respiratory medicine spraying technology, specifically a respiratory medicine spraying device. Background Technology

[0002] The Department of Respiratory Medicine mainly treats diseases of the respiratory system, which is mainly composed of the nose, pharynx, larynx, trachea, bronchi and lungs. Common respiratory diseases include colds, sore throats, asthma, tracheitis, bronchitis and so on. In the treatment process of respiratory medicine, some of the treatments require the use of a spray device to spray the medication into the nasal cavity or throat.

[0003] Most existing spraying devices use nebulizers to atomize the liquid medicine, which is then absorbed through inhalation. However, this method makes it difficult to control the amount of medicine inhaled by the patient. The treatment of respiratory diseases requires the drug to maintain a relatively stable concentration in the body. If the amount of medicine inhaled each time is inconsistent, the drug concentration will fluctuate greatly, making it difficult to maintain a sustained and effective effect. Although excessive dosage may have a noticeable effect in the short term, it cannot maintain a stable therapeutic effect, leading to recurring symptoms and affecting the overall control of the disease.

[0012] In one embodiment of the present invention, a first rotating shaft is rotatably installed inside the spraying trough, a second rotating shaft is rotatably installed inside the first rotating shaft, baffles are fixedly installed on the surfaces of both the first and second rotating shafts, a first base plate is fixedly installed at the bottom of the first rotating shaft, a second base plate is fixedly installed at the bottom of the second rotating shaft, and vertical rods are fixedly installed on the surfaces of both the first and second base plates.

[0013] In one embodiment of the present invention, a U-shaped plate is fixedly installed at the end of the fixed plate, and a horizontal plate is fixedly installed inside the U-shaped plate.

[0015] The present invention provides a respiratory medicine spray device, the beneficial effects of which include: 1. The spray mechanism ensures that the amount of medication and saline solution entering the nebulizer remains consistent each time the patient breathes. This consistent dosage avoids adverse reactions caused by excessive or insufficient medication. Excessive medication may cause local or systemic toxicity, while insufficient medication may not reach an effective therapeutic concentration, hindering the drug's effectiveness, delaying treatment, and potentially requiring increased dosage or duration of treatment due to poor disease control, thus increasing the risk of adverse reactions.

[0016] 2. The spray adjustment mechanism allows the entire device to adjust the air intake according to the strength of breathing. When the patient's breathing is strong, the spray adjustment mechanism allows more nebulized medication to enter the respiratory tract through the breathing tube, making full use of the airflow generated by strong breathing to deliver more medication to the lesion site. When breathing is weak, the dosage is reduced to reduce discomfort caused by nebulization, thereby improving their acceptance and cooperation with nebulization therapy and making the treatment more successful.

[0017] 3. Through the design of the induction switch and the micro motor, when the patient inhales, the induction switch is closed and the micro motor is stationary. When the patient has finished absorbing the nebulized medication and begins to exhale, the induction switch senses that the first and second base plates rotate in opposite directions, activating the two micro motors. This causes the medication and saline solution inside the storage tank to be injected into the nebulizer, producing nebulized medication. The design of the induction switch and the micro motor can prevent the waste of nebulized medication when the patient is not wearing the mask properly. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0022] Reference Figures 1-9This technical solution provides a respiratory medicine spray device, specifically including a handle 1. A spraying mechanism 2 is installed on the top of the handle 1. The spraying mechanism 2 includes a housing 201, a drug inlet 204, an atomizer 206, a spray head 208, and a face mask 210. The housing 201 is fixedly installed on the top of the handle 1. A partition 203 is fixedly installed inside the housing 201. The drug inlet 204 is located on the top of the housing 201. A drug storage tank 205 is fixedly installed at the bottom of the drug inlet 204. There are two drug storage tanks 205, which respectively store liquid medicine and saline solution. The operator injects the liquid medicine and saline solution into the two drug storage tanks 205 through the drug inlet 204. The saline solution can dilute the concentration of the liquid medicine. The medication, when used directly, may irritate the respiratory tract. Adding saline solution dilutes the medication to a suitable concentration, allowing it to distribute evenly within the respiratory tract for better efficacy. It also reduces irritation to the respiratory mucosa, lowering the incidence of adverse reactions such as coughing and wheezing. The nebulizer 206 is fixedly installed on the side of the partition 203. A connecting pipe 207 is fixedly installed between the nebulizer 206 and the drug reservoir 205. The medication and saline solution inside the drug reservoir 205 can enter the nebulizer 206 through the connecting pipe 207. A heater 231 is fixedly installed on the surface of the nebulizer 206. The nebulizer 206 atomizes the medication and saline solution, and the heater 231 heats the atomized medication at room temperature. Low-temperature nebulized liquid entering the respiratory tract may cause discomfort such as coughing and wheezing. Heated nebulized liquid is closer to body temperature, reducing cold stimulation to the respiratory tract and making patients feel more comfortable during nebulization. It is especially suitable for children, the elderly, and people with sensitive respiratory tracts. The spray head 208 is fixedly installed inside the outer shell 201. An air tube 209 is fixedly installed between the spray head 208 and the partition 203. The mask 210 is fixedly installed on the side of the spray head 208 and is connected to the spray head 208. The nebulizer 206 produces nebulized agent that enters the interior of the spray head 208 through the air tube 209, allowing the nebulizer to enter the interior of the mask 210. Slide plates 211 are slidably installed inside both medicine tanks 205. A toothed rod 212 is fixedly installed at the bottom of the slide plate 211, and a first mounting plate 213 is fixedly installed on the side of the partition plate 203. A mounting cylinder 214 is fixedly installed on the top of the first mounting plate 213. The mounting cylinder 214 is slidably connected to the toothed rod 212. A first through groove 215 is opened on the side of the mounting cylinder 214. When the toothed rod 212 moves inside the mounting cylinder 214, it can drive the slide plate 211 to move upward inside the medicine storage tank 205. The medicine and saline solution inside the medicine storage tank 205 are placed on the top of the slide plate 211. Therefore, when the slide plate 211 moves upward, it can drive the medicine and saline solution to move upward together, causing the water level of the medicine and saline solution to rise. When the water level rises to the position of the connecting pipe 207,The medication and saline solution can enter the nebulizer 206 through the connecting tube 207. Because the distance between the grooves of the toothed rod 212 is fixed, the rising height of the toothed rod 212 can be kept consistent each time. This ensures that the rising height of the slide plate 211 inside the drug reservoir 205 is also consistent each time. Consequently, the amount of medication and saline solution entering the nebulizer 206 is consistent each time the patient breathes, ensuring a consistent dosage of medication inhaled each time. Consistent inhalation volume avoids adverse reactions caused by excessive or insufficient medication. Excessive inhalation may cause local or systemic toxicity, while insufficient inhalation will not achieve an effective therapeutic concentration, failing to exert the drug's full effect, delaying treatment, and potentially requiring increased dosage or duration of use due to poor disease control, thus increasing the risk of adverse reactions.

[0023] Reference Figures 1-9This embodiment also proposes that a first mounting base 216 is fixedly installed on the side of the first through groove 215, a self-locking block 217 is rotatably installed inside the first mounting base 216, a second mounting base 218 is fixedly installed at the bottom of the first mounting base 216, a rubber sheet 219 is fixedly installed inside the second mounting base 218, a second through groove 220 is opened on the side of the mounting cylinder 214, a third mounting base 221 is fixedly installed on the side of the second through groove 220, a pawl 222 is rotatably installed inside the third mounting base 221, the pawl 222 meshes with the toothed bar 212, and a connecting rod 223 is rotatably installed at the end of the pawl 222. 3 is rotatably connected to the third mounting base 221. The surface of the partition plate 203 has two sliding grooves 224, each containing a sliding plate 225. The surface of each sliding plate 225 has a movable groove 226. The connecting rod 223 is movably connected to the movable groove 226. When the sliding plate 225 slides up and down inside the sliding groove 224, it moves the movable groove 226 up and down, which in turn moves the connecting rod 223 up and down, causing the rod head of the connecting rod 223 to rotate. This rotation of the connecting rod 223 causes the pawl 222 to engage. The reciprocating rotation of the rack 212 causes it to move upward, lifting the slide plate 211. Simultaneously, the rack 212 rotates, compressing the rubber sheet 219 and generating elastic potential energy. When the rack 212 reaches the tooth groove, the rubber sheet 219 acts as a stop, preventing the rack 212 from moving downward. Two micro motors 227 are fixedly installed inside the outer casing 201, with their output ends... Each component is fixedly equipped with a threaded rod 228. The end of the threaded rod 228 is rotatably connected to the partition plate 203. A threaded sleeve 229 is threadedly installed on the surface of the threaded rod 228. A rotating plate 230 is rotatably installed on the side of the threaded sleeve 229. The other end of the rotating plate 230 is rotatably connected to the sliding plate 225. When the micro motor 227 is started, it can drive the threaded rod 228 to reciprocate. Rotating the threaded rod 228 can cause the threaded sleeve 229 to reciprocate on the surface of the threaded rod 228, thereby causing the rotating plate 230 to reciprocate, which in turn causes the sliding plate 225 to reciprocate up and down inside the sliding groove 224.

[0024] Reference Figures 1-9This embodiment also proposes that the spray head 208 is internally equipped with a spray adjustment mechanism 3. The spray adjustment mechanism 3 includes a breathing groove 301, a breathing membrane 302 is fixedly installed inside the breathing groove 301, and a pressure sensor 303 is fixedly installed on the side of the breathing membrane 302. When the patient breathes, the breathing membrane 302 can deform. An electric telescopic rod 304 is fixedly installed inside the breathing groove 301. The pressure sensor 303 is connected to the electric telescopic rod 304 via an electrical signal. The pressure sensor 303 can generate different electrical signals according to the degree of deformation of the breathing membrane 302, so that the extension degree of the electric telescopic rod 304 can be controlled according to the strength of the patient's breathing. When the patient's breathing is weak, the electric telescopic rod 304 extends to a shorter length, and when the patient's breathing is strong, the electric telescopic rod 304 extends to a longer length. A first rotating rod 305 is rotatably installed at the telescopic end of the electric telescopic rod 304. The device includes a bracket 306, inside which a second rotating rod 307 is rotatably mounted. The bottom of the second rotating rod 307 is rotatably connected to the first rotating rod 305. The spray head 208 has a spray groove 308 inside, and a slide rail 309 is fixedly mounted inside the spray groove 308. A fixing plate 310 is slidably mounted inside the slide rail 309. A third rotating rod 311 is rotatably mounted at the end of the fixing plate 310. The other end of the third rotating rod 311 is rotatably connected to the top of the second rotating rod 307. The extension and retraction of the electric telescopic rod 304 can cause the first rotating rod 305 to rotate. The rotation of the first rotating rod 305 can drive the second rotating rod 307 to rotate inside the bracket 306. The rotation of the second rotating rod 307 can drive the third rotating rod 311 to rotate, which in turn can push the fixing plate 310 to slide inside the slide rail 309. The distance that the fixing plate 310 slides inside the slide rail 309 varies depending on the strength of the patient's breathing.

[0025] Reference Figures 1-9This embodiment also proposes that a first rotating shaft 312 is rotatably installed inside the spraying trough 308, and a second rotating shaft 313 is rotatably installed inside the first rotating shaft 312. Baffles 314 are fixedly installed on the surfaces of both the first and second rotating shafts 312 and 313. A first base plate 315 is fixedly installed at the bottom of the first rotating shaft 312, and a second base plate 316 is fixedly installed at the bottom of the second rotating shaft 313. Vertical rods 317 are fixedly installed on the surfaces of both the first and second base plates 315 and 316. A U-shaped plate 318 is fixedly installed at the end of the fixing plate 310. A horizontal plate 319 is fixedly installed inside the U-shaped plate 318. Two horizontal plates 319 are provided, and a third through groove 320 is opened on the surface of each of the two horizontal plates 319. The vertical rods 317 and... The third through groove 320 is movably connected. When the fixed plate 310 slides inside the slide rail 309, it can drive the U-shaped plate 318 to move, which in turn can drive the horizontal plate 319 to move. Because the surface of the horizontal plate 319 has the third through groove 320, and the third through groove 320 is movably connected to the vertical rod 317, when the horizontal plate 319 moves, it can drive the vertical rod 317 to slide inside the third through groove 320. Since the third through groove 320 moves together with the horizontal plate 319, the vertical rod 317 can perform circular motion. And since the vertical rod 317 is fixedly connected to the first base plate 315 and the second base plate 316, the vertical rod 317 fixed on the first base plate 315 and the second base plate 316 moves. When rotated, the first base plate 315 and the second base plate 316 rotate together. The rotation of the first base plate 315 and the second base plate 316 drives the first rotating shaft 312 and the second rotating shaft 313 to rotate together. The rotation of the first rotating shaft 312 and the second rotating shaft 313 drives the baffles 314 to rotate together, causing the two baffles 314 to open and close. When the patient's breathing is weak, the fixed plate 310 slides a shorter distance inside the slide rail 309, resulting in a smaller rotation amplitude of the first base plate 315 and the second base plate 316, and consequently a smaller opening and closing angle of the two baffles 314. This results in a smaller amount of nebulized agent passing through the breathing groove 301. Conversely, when the patient's breathing is stronger, the fixed plate 310 slides a shorter distance inside the slide rail 309. The longer sliding distance allows for a larger rotation range of the first base plate 315 and the second base plate 316, resulting in a larger opening and closing angle of the two baffles 314. This allows for a larger amount of nebulized agent passing through the breathing groove 301. When the patient's breathing is strong, the spray adjustment mechanism 3 allows more nebulized agent to enter the respiratory tract through the breathing tube, making full use of the airflow generated by strong breathing to deliver more medication to the lesion site. When breathing is weak, the dosage is reduced to minimize discomfort caused by nebulization, thereby improving the patient's acceptance and cooperation with nebulization therapy and enabling the treatment to proceed more smoothly. A protective plate 321 is fixedly installed on the side of the spray head 208. The protective plate 321 is slidably connected to the U-shaped plate 318, and an induction switch 322 is fixedly installed inside the protective plate 321.The induction switch 322 is electrically connected to two micro motors 227. The induction switch 322 can sense the rotation of the first base plate 315 and the second base plate 316. When the first base plate 315 and the second base plate 316 rotate in opposite directions, the induction switch 322 receives a signal, causing the two micro motors 227 to start. Through the settings of the induction switch 322 and the micro motors 227, when the patient inhales, the induction switch 322 closes and the micro motors 227 stop. When the patient has finished absorbing the nebulized medication, they begin to exhale. At this time, the induction switch 322 senses that the first base plate 315 and the second base plate 316 rotate in opposite directions, activating the two micro motors 227. This causes the medication and saline solution inside the medicine tank 205 to be injected into the nebulizer 206, producing nebulized medication. The induction switch 322 and the micro motors 227 prevent waste of nebulized medication if the patient is not properly wearing the mask 210. The handle 1 has a battery compartment 4 inside, a main switch 5 fixedly installed on its surface, and a power indicator light 6 on its surface.

[0026] Specifically, the working process or principle of this respiratory medicine spray device is as follows: Two drug storage tanks 205 respectively store liquid medication and saline solution. The operator injects the liquid medication and saline solution into the two storage tanks 205 through the injection port 204. The saline solution dilutes the concentration of the liquid medication. Direct use of the liquid medication may irritate the respiratory tract; adding saline solution dilutes the medication to a suitable concentration, allowing for even distribution within the respiratory tract and better efficacy. Simultaneously, it reduces irritation to the respiratory mucosa, lowering the incidence of coughing, wheezing, and other adverse reactions. The nebulizer 206 atomizes the liquid medication and saline solution, and the heater 231 heats the atomized medication. The atomized medication generated by the nebulizer 206 enters the spray head 208 through the trachea 209, allowing the atomized medication to enter the face mask. Inside 210, when the toothed rod 212 moves inside the mounting cylinder 214, it can drive the slide plate 211 to move upward inside the medicine tank 205. The medicine and saline solution inside the medicine tank 205 are placed on the top of the slide plate 211. Therefore, when the slide plate 211 moves upward, it can drive the medicine and saline solution to move upward together, causing the water level of the medicine and saline solution to rise. When the water level rises to the position of the connecting pipe 207, the medicine and saline solution can enter the nebulizer 206 through the connecting pipe 207. Because the distance between the tooth grooves of the toothed rod 212 is fixed, the rising height of the toothed rod 212 can be kept consistent each time, so that the rising height of the slide plate 211 inside the medicine tank 205 can be kept fixed each time, thereby ensuring that the amount of medicine and saline solution entering the nebulizer 206 is consistent each time.

[0027] When a patient breathes, the breathing membrane 302 deforms. The pressure sensor 303 generates different electrical signals based on the degree of deformation of the breathing membrane 302, allowing the extension and retraction of the electric telescopic rod 304 to be controlled according to the strength of the patient's breathing. When the patient's breathing is weak, the electric telescopic rod 304 extends to a shorter length, while when the patient's breathing is strong, the electric telescopic rod 304 extends to a longer length. The extension and retraction of the electric telescopic rod 304 causes the first rotating rod 305 to rotate. The rotation of the first rotating rod 305 drives the second rotating rod 307 to rotate inside the support 306. The rotation of the second rotating rod 307 drives the third rotating rod 311 to rotate, which in turn pushes the fixed plate 310 to slide inside the slide rail 309. The distance that the fixed plate 310 slides inside the slide rail 309 varies depending on the strength of the patient's breathing.When the fixed plate 310 slides inside the slide rail 309, it can drive the U-shaped plate 318 to move, which in turn can drive the horizontal plate 319 to move. Because the surface of the horizontal plate 319 has a third through groove 320, and the third through groove 320 is movably connected to the vertical rod 317, when the horizontal plate 319 moves, it can drive the vertical rod 317 to slide inside the third through groove 320. Since the third through groove 320 moves along with the horizontal plate 319, the vertical rod 317 can then undergo circular motion. Furthermore, because the vertical rod 317 is connected to the first base plate 315 and the... The two base plates 316 are fixedly connected. Therefore, when the vertical rod 317 fixed on the first base plate 315 and the second base plate 316 rotates, it can drive the first base plate 315 and the second base plate 316 to rotate together. The rotation of the first base plate 315 and the second base plate 316 can drive the first rotating shaft 312 and the second rotating shaft 313 to rotate together. The rotation of the first rotating shaft 312 and the second rotating shaft 313 can drive the baffle 314 to rotate together, so that the two baffles 314 can open and close. When the patient's breathing is weak, the fixed plate 310 slides within the slide rail 309 for a distance of... The distance between the first base plate 315 and the second base plate 316 is relatively short, resulting in a smaller rotation range and consequently a smaller opening and closing angle of the two baffles 314. This reduces the amount of nebulized agent passing through the breathing groove 301. Conversely, when the patient's breathing is stronger, the fixed plate 310 slides a longer distance within the slide rail 309, resulting in a larger rotation range of the first base plate 315 and the second base plate 316. This leads to a larger opening and closing angle of the two baffles 314 and a larger amount of nebulized agent passing through the breathing groove 301. The inductive switch 322 can sense the rotation of the first base plate 315 and the second base plate 316. When the first base plate 315... When the first base plate 315 and the second base plate 316 rotate in opposite directions, the induction switch 322 receives a signal, activating the two micro motors 227. Based on the settings of the induction switch 322 and the micro motors 227, when the patient inhales, the induction switch 322 closes, and the micro motors 227 remain stationary. When the patient has finished absorbing the nebulized medication and begins to exhale, the induction switch 322 senses the reverse rotation of the first base plate 315 and the second base plate 316, activating the two micro motors 227. This causes the medication and saline solution inside the drug reservoir 205 to be injected into the nebulizer 206, producing nebulized medication.

[0028] When the sliding plate 225 slides up and down inside the sliding groove 224, it drives the movable groove 226 to move up and down, which in turn drives the rod body of the connecting rod 223 to move up and down. This causes the rod head of the connecting rod 223 to rotate. The rotation of the connecting rod 223 drives the pawl 222 to rotate reciprocally, thereby causing the rack 212 to move upward and lift the slide plate 211 upward. As the rack 212 moves upward, it can rotate the self-locking block 217, which can compress the rubber sheet 219. This causes the rubber sheet 219 to deform, generating elastic potential energy. When the toothed rod 212 moves to the tooth groove, the self-locking block 217 can abut against the tooth groove under the action of the rubber sheet 219, preventing the toothed rod 212 from moving downward. When the micro motor 227 starts, it can drive the threaded rod 228 to reciprocate. Rotating the threaded rod 228 can cause the threaded sleeve 229 to reciprocate on the surface of the threaded rod 228, thereby causing the rotating plate 230 to reciprocate, and thus causing the sliding plate 225 to reciprocate up and down inside the sliding groove 224.
