Description

Technical Field

[0001] This invention relates to the field of respiratory system therapeutic devices, and more specifically to clinical inhaled drug delivery devices for respiratory systems. Background Technology

[0002] Inhaled respiratory medication devices are targeted therapies that deliver liquid drugs as tiny aerosol particles through the mouth and nose, directly to the respiratory tract lesions. They are widely used for treating respiratory diseases, utilizing compressed gas, ultrasonic oscillation, or microporous mesh technology to atomize the medication. These devices offer advantages such as rapid onset of action, high local drug concentration, and minimal systemic side effects, and are widely used in the treatment of respiratory diseases such as asthma and COPD. While traditional nebulizers, such as jet or ultrasonic nebulizers, can perform basic nebulization, when patients require multiple nebulizations per day, the limited liquid capacity of the nebulizer and the need for repeated medication additions and patient cleaning and drying after each treatment, especially for patients requiring long-term, frequent administration, not only increase workload but also affect patient compliance. In addition, cleaning the device after use often relies on water washing. Residual moisture in the damp atomization chamber and tubing is difficult to dry completely over a long period of time. This not only increases the preparation time before the next use, but also provides a breeding ground for bacteria (such as Gram-negative bacteria and Streptococcus pneumoniae), which may lead to the risk of cross-infection. It is necessary to optimize the drug delivery process and the design of rapid drying to improve clinical safety and usage efficiency.

[0003] Therefore, this application designs a respiratory system clinical inhalation drug delivery device that can store a large amount of drug solution for automatic replenishment and automatic drying. Summary of the Invention

[0004] The purpose of this invention is to provide a clinical inhaled drug delivery device for the respiratory system, which aims to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clinical inhalation drug delivery device for the respiratory system, comprising a reservoir, an ultrasonic nebulizer, and a charging base for disinfecting and drying the nebulizer; the reservoir is placed on a bedside table, the lower end of the charging base is fixedly connected to the upper end of the reservoir, and the nebulizer is slidably engaged with the charging base.

[0006] A screw conveyor is rotatably installed inside the liquid storage tank. A through feeding channel is provided in the middle of the upper end of the liquid storage tank. The feeding channel is coaxial with the screw conveyor. A limit cylinder is also fixedly connected to the lower part of the upper end of the liquid storage tank. The inner circumference of the limit cylinder contacts the outer circumference of the screw conveyor. Openings are provided on both sides of the upper part of the limit cylinder.

[0007] Two sets of rotating doors are symmetrically arranged at the upper end of the liquid storage cylinder, and the rotating doors are hinged to the inner wall of the liquid storage cylinder with torsion springs; two sets of pins are fixedly connected to the lower two sides of the atomizer, and a snap-fit ​​cylinder is provided at the lower end of the atomizer to connect to the inside of the atomizer.

[0008] The rotating screw conveyor transports the liquid medicine from the bottom of the storage tank to the upper part of the limiting cylinder. The liquid medicine falls back to the liquid surface through the opening. The atomizer slides into the charging base for charging. The feeding channel slides into the inner circumference of the clamping cylinder. The pin enters the inside of the storage tank through the rotating door and blocks the opening. The rotating screw conveyor feeds the liquid medicine into the atomizer through the feeding channel.

[0009] The medication is stored in a reservoir, and a continuously rotating screw conveyor transports the lower layer of medication from the reservoir to the opening, ensuring uniform mixing and preventing sedimentation from prolonged storage. When the nebulizer is needed, it is pressed down along the charging base, engaging the feeding channel at the bottom of the nebulizer. The nebulizer slot then rotates through a door into the reservoir, blocking the opening. The screw conveyor then delivers the medication through the feeding channel to the nebulizer, enabling automatic refilling. This reduces the need for frequent medication refills by medical staff, allowing patients to quickly replenish their medication themselves, effectively reducing the workload of medical personnel and improving work efficiency.

[0010] Furthermore, both the feeding channel and the clamping cylinder are equipped with one-way valves, and the upper end of the liquid storage cylinder is also equipped with a one-way air hole and a feed inlet. The atomizer includes an atomizing cover, a connecting pipe, an atomizing chamber, a battery compartment, and a magnetic charging plate. The lower end of the atomizing cover is threaded to one end of the connecting pipe, and the other end of the connecting pipe is welded and fixed to the upper end of the atomizing chamber. The lower end of the atomizing chamber is connected to the clamping cylinder. The battery compartment is fixedly installed on the side of the atomizing chamber, and the magnetic charging plate is fixedly connected to the rear end of the battery compartment.

[0011] Piezoelectric crystals are installed on the periphery of the atomization chamber to atomize the internal liquid drug through ultrasonic vibration.

[0012] The protective shell of the battery compartment forms a grip, and there are sliding grooves on both sides of the grip.

[0013] Furthermore, the screw conveyor includes a rotating rod and an auger. The inner circumference of the auger is welded and fixed to the outer circumference of the rotating rod. The outer circumference of the auger contacts the inner circumference of the limiting cylinder. The lower end of the rotating rod passes through the bottom wall of the liquid storage cylinder and is connected to a transmission component. The rotating rod and the liquid storage cylinder have a sealed rotating connection.

[0014] Furthermore, the charging base includes a support base and a limiting slide rail; the support base has a receiving groove for accommodating the atomizer, the inner wall of the receiving groove is made of soft material, the two ends of the limiting slide rail are welded and fixed to the support base, the inner circumference of the limiting slide rail is slidably connected to the grip part through a sliding groove, and the charger is provided on the inner circumference of the limiting slide rail.

[0015] Meanwhile, the combination of magnetic charging and ultrasonic nebulizer allows the charging base to guide the connection between the nebulizer and the feeding channel, eliminating the need to connect gas pipes to the nebulizer. This frees patients from the constraints of tubing and power cords, enabling them to receive treatment anywhere, which is beneficial to their mental health and reduces the number of treatment interruptions.

[0016] Furthermore, the interior of the receiving tank is provided with a step, and an ultraviolet disinfection lamp is installed on the side of the step. A drying assembly is fixedly connected to the upper end of the step. The drying assembly includes an air hole, a turbine, a heating wire, and an inclined air nozzle; the air hole is opened in the middle of the step, passes through the side of the liquid storage cylinder and extends downward, and an air inlet is opened on the side of the liquid storage cylinder and communicates with the air hole. The outer periphery of the turbine is movable with the inner wall of the air hole, and the heating wire is set in the inner periphery of the air hole and positioned on the upper part of the turbine;

[0017] The lower end of the tilted nozzle is fixedly connected to the air hole end, and the middle part of the turbine is inserted into the transmission component.

[0018] With the addition of ultraviolet disinfection lamps and drying components, after a patient completes a single treatment and washes the nebulizer, the nebulizer is directly inserted into the charging base. Driven by the transmission component, the drying component slowly dries the inside of the nebulizer with hot air, while the ultraviolet disinfection lamp irradiates and disinfects the nebulizer. This process quickly removes moisture from the inner wall of the nebulizer, making it easier for the next use, and effectively inhibits the growth and reproduction of bacteria inside, thus reducing the risk of cross-infection and improving the safety of clinical treatment.

[0019] Furthermore, the lower end of the liquid storage cylinder is also located in the transmission chamber, and the transmission assembly is positioned inside the transmission chamber. The transmission assembly includes a drive motor, a drive gear, a driven gear, an electromagnetic pin, and a connecting rod. The drive motor is bolted to the bottom wall of the transmission chamber, and the output end of the drive motor is inserted into the side of the rotating rod away from the auger. The inner circumference of the drive gear is fixedly connected to the side of the rotating rod close to the drive motor.

[0020] The lower end of the electromagnetic pin is rotatably connected to the bottom wall of the transmission chamber, the upper end of the electromagnetic pin is fixedly connected to the lower end of the driven gear, the lower end of the connecting rod is inserted into the upper end of the driven gear, and the other end of the connecting rod extends into the air hole and is inserted into the middle of the turbine. A dynamic seal is provided at the contact position between the connecting rod and the air hole.

[0021] Furthermore, a filter is installed at the air inlet. The system also includes a controller, charging dock, and transmission components, all of which are electrically connected to the controller.

[0022] Compared with existing technologies, it has the following beneficial effects:

[0023] The medication is stored in a reservoir, and a continuously rotating screw conveyor transports the lower layer of medication from the reservoir to the opening, ensuring uniform mixing and preventing sedimentation from prolonged storage. When the nebulizer is needed, it is pressed down along the charging base, engaging the feeding channel at the bottom of the nebulizer. The nebulizer slot then rotates through a door into the reservoir, blocking the opening. The screw conveyor then delivers the medication through the feeding channel to the nebulizer, enabling automatic refilling. This reduces the need for frequent medication refills by medical staff, allowing patients to quickly replenish their medication themselves, effectively reducing the workload of medical personnel and improving work efficiency.

[0024] Meanwhile, by combining magnetic charging and ultrasonic nebulizer, the charging base guides the connection between the nebulizer and the feeding channel, eliminating the need to connect gas pipes to the nebulizer. This allows patients to receive treatment anywhere without being restricted by tubing or power cords, which is beneficial to their mental health and reduces the number of treatment interruptions.

[0025] With the addition of ultraviolet disinfection lamps and drying components, after a patient completes a single treatment and washes the nebulizer, the nebulizer is directly inserted into the charging base. Driven by the transmission component, the drying component slowly dries the inside of the nebulizer with hot air, while the ultraviolet disinfection lamp irradiates and disinfects the nebulizer. This process quickly removes moisture from the inner wall of the nebulizer, making it easier for the next use, and effectively inhibits the growth and reproduction of bacteria inside, thus reducing the risk of cross-infection and improving the safety of clinical treatment.

Detailed Implementation

[0037] To better understand the structure, functional features, and advantages of the present invention, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings:

[0038] like Figures 1 to 9 As shown, this application proposes a clinical inhalation drug delivery device for the respiratory system, including a reservoir 1, an ultrasonic nebulizer 2, and a charging base 3 for disinfecting and drying the nebulizer 2; the reservoir 1 is placed on the bedside table, the lower end of the charging base 3 is fixedly connected to the upper end of the reservoir 1, and the nebulizer 2 is slidably engaged with the charging base 3.

[0039] A screw conveyor 4 is rotatably installed inside the liquid storage cylinder 1. A through feeding channel 11 is provided in the middle of the upper end of the liquid storage cylinder 1. The feeding channel 11 is coaxial with the screw conveyor 4. A limiting cylinder 12 is also fixedly connected to the lower part of the upper end of the liquid storage cylinder 1. The inner circumference of the limiting cylinder 12 contacts the outer circumference of the screw conveyor 4. Openings 13 are provided on both sides of the upper part of the limiting cylinder 12.

[0040] Two sets of rotating doors 14 are symmetrically arranged at the upper end of the liquid storage cylinder 1. The rotating doors 14 are hinged to the inner wall of the liquid storage cylinder 1 with torsion springs. A snap-fit ​​cylinder 21 is provided at the lower end of the atomizer 2, which is connected to the interior of the atomizer 2. Two sets of pins 22 are fixedly connected to both sides of the snap-fit ​​cylinder 21.

[0041] The rotating screw conveyor 4 transports the liquid medicine at the bottom of the storage cylinder 1 to the upper part of the limiting cylinder 12. The liquid medicine falls back to the liquid surface through the opening 13. The atomizer 2 slides into the charging base 3 for charging. The feeding channel 11 slides into the inner circumference of the clamping cylinder 21. The pin 22 enters the interior of the storage cylinder 1 through the rotating door 14 and blocks the opening 13. The rotating screw conveyor 4 sends the liquid medicine into the interior of the atomizer 2 through the feeding channel 11.

[0042] It should be noted that both the feeding channel 11 and the clamping cylinder 21 are equipped with one-way valves. The one-way valves ensure that the liquid medicine can only flow to the nebulizer 2 through the storage cylinder 1. At the same time, after the feeding channel 11 is inserted into the clamping cylinder 21, the two sets of one-way valves are close to each other, so that there is no gap between them, preventing a small amount of liquid leakage after feeding. The upper end of the storage cylinder 1 is also equipped with a one-way air hole and a feed inlet. Medical staff add liquid medicine to the storage cylinder 1 through the feed inlet. The lower end of the storage cylinder 1 is also equipped with a discharge port to facilitate the discharge of the remaining liquid medicine. At the same time, the side of the storage cylinder 1 can be equipped with an observation window and scale lines to facilitate the observation of the internal liquid medicine volume and state.

[0043] As another embodiment, such as Figures 2 to 7 As shown, the atomizer 2 includes an atomizing cover 23, a connecting tube 24, an atomizing chamber 25, a battery compartment 26, and a magnetic charging plate 27; the lower end of the atomizing cover 23 is threadedly connected to one end of the connecting tube 24, and the other end of the connecting tube 24 is welded and fixed to the upper end of the atomizing chamber 25; the lower end of the atomizing chamber 25 is connected to the snap-fit ​​tube 21; the battery compartment 26 is fixedly disposed on the side of the atomizing chamber 25; and the magnetic charging plate 27 is fixedly connected to the rear end of the battery compartment 26.

[0044] A piezoelectric crystal is installed on the inner circumferential side of the atomization chamber 25 to atomize the internal liquid drug through ultrasonic vibration.

[0045] The electromagnetic chamber is waterproof and provides power to drive the piezoelectric crystal, which atomizes the medication through ultrasonic vibration. The atomized medication moves upward through the atomization chamber 25 and is released into the atomization mask 23 through the connecting tube 24. Patients can receive inhalation therapy by placing their mouth and nose inside the atomization mask 23 and breathing normally. Furthermore, elastic restraint straps can be installed on both sides of the atomization mask 23. By placing the elastic restraint straps behind the head, patients do not need to hold the atomizer 2 for a long time.

[0046] The protective shell of the battery compartment 26 forms a grip 28, and the grip 28 has grooves 281 on both sides. The rear end of the grip 28 has an ergonomic design to facilitate hand gripping. The grip 28 allows patients to hold the device for a long time while making it easy to pick up and place the nebulizer 2. When charging or refilling is needed, the nebulizer 2 can be accurately placed by aligning the grooves 281 with the corresponding positions on the charging base 3, so that the pin 22 and the locking tube 21 at the bottom of the nebulizer 2 can be directly and quickly engaged with its cooperating components.

[0047] See Figure 4 as well as Figure 5 The screw conveyor 4 includes a rotating rod 41 and an auger 42. The inner circumference of the auger 42 is welded and fixed to the outer circumference of the rotating rod 41. The outer circumference of the auger 42 is in contact with the inner circumference of the limiting cylinder 12. The lower end of the rotating rod 41 passes through the bottom wall of the liquid storage cylinder 1 and is connected to a transmission assembly 5. The rotating rod 41 and the liquid storage cylinder 1 have a sealed rotating connection.

[0048] The upper end of the limiting cylinder 12 is fixed to the top wall of the storage cylinder 1, and the lower end of the limiting cylinder 12 does not contact the bottom wall of the storage cylinder 1, thus forming a feeding space for feeding into the screw conveyor 4. When the rotating rod 41 is driven by the transmission component 5 to rotate, the rotating rod 41 drives the auger 42 to rotate synchronously. The auger 42 rotates and drives the liquid medicine to move upward along the limiting cylinder 12 and flow out through the opening 13 at the upper end of the limiting cylinder 12, so that the liquid medicine inside the storage cylinder 1 will not precipitate.

[0049] Additionally, it should be noted that the rotating door 14 is located on the top wall of the liquid storage cylinder 1. The torsion spring of the rotating door 14 keeps the rotating door 14 in a closed state for a long time under normal conditions. When the atomizer 2 is placed in the charging base 3, its pin 22 is inserted into the upper end of the rotating door 14. Under the action of the torsion spring of the rotating door 14, the rotating door 14 is in a closed state without the intervention of other external forces.

[0050] When refilling is required, pressing the grip 28 causes the atomizer 2 to continue moving downwards, which in turn causes the pin 22 to drive the rotating door 14 to rotate. The pin 22 enters the liquid storage tank 1 and seals the opening 13. At the same time, the feeding channel 11 is fully inserted into the clamping cylinder 21. The liquid cannot fall through the opening 13 and, driven by the auger 42, it enters the atomization chamber 25 through the feeding channel 11. After feeding is completed, the atomizer 2 is pulled out directly, the pin 22 disengages from the liquid storage tank 1, and the rotating door 14 rotates in the opposite direction under the action of the torsion spring, returning to the closed state.

[0051] See Figure 3 , Figure 4 , Figure 6 as well as Figure 7 The charging base 3 includes a support base 31 and a limiting slide rail 32. The support base 31 has a receiving groove 311 for accommodating the atomizer 2. The inner wall of the receiving groove 311 is made of soft material. The two ends of the limiting slide rail 32 are welded and fixed to the support base 31. The inner circumference of the limiting slide rail 32 is slidably connected to the grip part 28 through the slide groove 281. The charger 321 is provided on the inner circumference of the limiting slide rail 32.

[0052] The inner circumference of the receiving slot 311 is designed to fit the shape of the atomizer 2, so that the atomizer 2 can be smoothly placed inside the receiving slot 311 from top to bottom. At the same time, by aligning the sliding groove 281 at the rear end of the grip 28 with the limiting slide rail 32, the atomizer 2 is inserted into the charging base 3 from top to bottom. The pin 22 at the lower end of the atomizer 2 and the locking tube 21 are naturally aligned with the rotating door 14 and the feeding channel 11. Meanwhile, the magnetic charging plate 27 at the rear end of the grip 28 is magnetically connected to the charger 321 of the limiting slide rail 32 to charge the battery compartment 26.

[0053] See Figure 7 The receiving slot 311 has a step 312 inside, and an ultraviolet disinfection lamp 313 is installed on the side of the step 312. A drying component 33 is fixedly connected to the upper end of the step 312. After the nebulizer 2 is placed on the charging base 3 and the magnetic charging plate 27 contacts the charger 321 to start charging, the ultraviolet disinfection lamp 313 is activated. By continuously irradiating the inside of the nebulizer cover 23 with ultraviolet light, the growth of bacteria inside is prevented. Furthermore, the outer layer of the nebulizer cover 23 can be coated with a light-shielding coating to reduce the patient's discomfort from prolonged exposure to ultraviolet light.

[0054] As another embodiment, see Figures 7 to 9As shown, the drying assembly 33 includes an air vent 331, a turbine 332, a heating wire 333, and an inclined air nozzle 334. The air vent 331 is located in the middle of the step 312, and extends through the side of the liquid storage tank 1 and downwards. An air inlet 15 is provided on the side of the liquid storage tank 1 and communicates with the air vent 331. The outer periphery of the turbine 332 is movably connected to the inner wall of the air vent 331. The heating wire 333 is disposed on the inner periphery of the air vent 331 and is positioned on the upper part of the turbine 332.

[0055] The lower end of the tilting nozzle 334 is fixedly connected to the end of the air hole 331, and the middle part of the turbine 332 is inserted into the transmission assembly 5.

[0056] When the atomizer 2 starts charging, the transmission component 5 drives the turbine 332 to rotate. The rotation of the turbine 332 causes the gas to enter the air hole 331 through the air inlet 15 and move upward along the air hole 331. The gas after passing through the turbine 332 is heated by the heating wire 333 to form hot air, and finally blown into the atomizing cover 23 through the tilted air nozzle 334, so that the atomizer 2 after being washed can be dried by hot air.

[0057] See Figure 8 as well as Figure 9 The lower end of the liquid storage cylinder 1 is also provided in the transmission chamber 16. The transmission component 5 is positioned inside the transmission chamber 16. The transmission component 5 includes a drive motor 51, a drive gear 52, a driven gear 53, an electromagnetic pin 54, and a connecting rod 55. The drive motor 51 is bolted to the bottom wall of the transmission chamber 16. The output end of the drive motor 51 is inserted into the side of the rotating rod 41 away from the auger 42. The inner circumference of the drive gear 52 is fixedly connected to the side of the rotating rod 41 close to the drive motor 51.

[0058] Under normal power-on conditions, the output of the drive motor 51 directly drives the rotating rod 41 to rotate, thereby causing the screw conveyor 4 to rotate continuously to prevent the sedimentation of the medicine. The rotating rod 41 and the liquid storage tank 1 are connected by a sealing structure to prevent leakage of the medicine. While the rotating rod 41 rotates, it drives the drive gear 52 to rotate continuously. Under normal conditions, the drive gear 52 and the driven gear 53 are not in a meshing state. When hot air drying is required, the electromagnetic pin 54 is activated, pushing the driven gear 53 to move upward and mesh with the drive gear 52. The driven gear 53 is continuously rotated by the drive gear 52 and the rotation is transmitted to the turbine 332 through the connecting rod 55, so that the turbine 332 starts to draw air through the air inlet 15.

[0059] The lower end of the electromagnetic pin 54 is rotatably connected to the bottom wall of the transmission chamber 16, the upper end of the electromagnetic pin 54 is fixedly connected to the lower end of the driven gear 53, the lower end of the connecting rod 55 is inserted into the upper end of the driven gear 53, and the other end of the connecting rod 55 extends into the air hole 331 and is inserted into the middle of the turbine 332. A dynamic seal is provided at the contact position between the connecting rod 55 and the air hole 331.

[0060] It should be noted that a filter is installed at the air inlet 15. The filter is plug-in and can be replaced after a certain period of use.

[0061] In addition, the controller, charging base 3, and transmission assembly 5 are all electrically connected to the controller. The controller directly controls the start and stop of the drive motor 51, electromagnetic pin 54, ultraviolet lamp, and heating wire 333; the controller integrated circuit can be an NXP-MK26 microcontroller.

[0062] Working principle:

[0063] Under normal power-on conditions, when the rotating rod 41 is driven to rotate by the transmission component 5, the rotating rod 41 drives the auger 42 to rotate synchronously. The auger 42 then drives the liquid medicine upward along the limiting cylinder 12 and flows out through the opening 13 at the upper end of the limiting cylinder 12, preventing the liquid medicine inside the storage cylinder 1 from settling. When refilling is required, pressing the grip part 28 causes the atomizer 2 to continue moving downward, which in turn causes the pin 22 to drive the rotating door 14 to rotate. The pin 22 enters the storage cylinder 1 and seals the opening 13. At the same time, the feeding channel 11 is fully inserted into the clamping cylinder 21. The auger 42 drives the liquid medicine into the atomization chamber 25 through the feeding channel 11. After feeding is completed, the atomizer 2 is pulled out directly, the pin 22 disengages from the storage cylinder 1, and the rotating door 14 rotates in the opposite direction under the action of the torsion spring, returning to the closed state.

[0064] After completing a single treatment and rinsing the atomizer 2, the atomizer 2 is inserted from top to bottom into the charging base 3 by aligning the groove 281 at the rear end of the grip 28 with the limiting slide rail 32. The pin 22 at the lower end of the atomizer 2 and the locking tube 21 are naturally aligned with the rotating door 14 and the feeding channel 11. At the same time, the magnetic charging plate 27 at the rear end of the grip 28 is magnetically connected to the charger 321 on the limiting slide rail 32 to charge the battery compartment 26. After charging begins, the ultraviolet disinfection lamp 313 is activated, continuously irradiating the inside of the atomizing cover 23 with ultraviolet light to prevent the growth of bacteria inside. At the same time, the electromagnetic pin 54 is activated, causing the driven gear 53 to rotate continuously under the transmission of the driving gear 52, and the rotation is transmitted to the turbine 332 through the connecting rod 55. The turbine 332 then begins to draw air through the air inlet 15, and the air is heated by the heating wire and blown into the inside of the atomizing cover 23 through the inclined nozzle 334 for hot air drying.

Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention.
