Description

Technical Field

[0001] This invention relates to the field of nebulization device technology, specifically a portable lung cancer nebulization respiratory therapy device. Background Technology

[0002] Nebulized inhalation therapy is an important treatment for respiratory diseases, widely used as an adjunct therapy for various airway and lung conditions such as colds, coughs, asthma, bronchitis, and pneumoconiosis. Its core component, the nebulizer, transforms liquid medication into fine aerosol particles, allowing the drug to be directly deposited on the respiratory mucosa or alveolar surface, thus achieving localized drug delivery and rapid onset of action. With its non-invasive and highly targeted advantages, this technology has become an indispensable medical device in clinical and home care.

[0003] Current nebulizers exhibit two structural problems in practical applications: First, the connection between the mouthpiece and the tubing lacks a reliable anti-detachment design, making it prone to detachment during patient pulling or device movement, leading to treatment interruption and potential medication waste. Second, the method of filling the air inlet with medical dry cotton for filtering airborne impurities has significant drawbacks; manual filling makes it difficult to ensure uniform fiber density, easily creating through-holes that allow unfiltered impurities to directly enter the nebulization chamber, affecting medication purity and potentially accelerating wear and blockage of internal precision components (such as the compressor and nebulizer plate). These problems directly impact the continuity of treatment and the long-term reliability of the device. Therefore, we propose a portable lung cancer nebulized respiratory therapy device. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a portable lung cancer nebulized respiratory therapy device that can achieve rapid and non-detachable connection of the air delivery hose and can uniformly compress the air intake filter cotton to improve the filtration effect, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a portable lung cancer nebulization respiratory therapy device, comprising a nebulizer and an air outlet assembly; Atomizer: A handle is fixed on the upper side, and a rubber sleeve is fixed on the surface of the handle. Two corresponding arc-shaped cards are fixed on the right side of the atomizer. A filter assembly is installed inside the air inlet on the front side of the atomizer. A moving assembly is installed at the front end of the filter assembly. A squeezing assembly is installed at the rear end of the moving assembly. The rear end of the squeezing assembly is located inside the filter assembly. Air outlet assembly: includes an air outlet pipe, a fixing ring, a rotating ring, a torsion spring, a connecting plate, and an arc-shaped locking rod. An air outlet pipe is fixed inside the air inlet located on the right side of the atomizer. A fixing ring is fixed to the left end of the circumference of the air outlet pipe. A rotating ring and a torsion spring are sleeved on the right end of the circumference of the air outlet pipe. The left end of the torsion spring is fixed to the right end of the fixing ring, and the right end of the torsion spring is fixed to the left end of the rotating ring. Evenly distributed connecting plates are fixed to the circumference of the rotating ring. An arc-shaped locking rod is fixed to the right end of each connecting plate. An air guide assembly is installed on the right end of the surface of the air outlet pipe. The air delivery assembly is connected to all the curved levers. The nebulizer is the core component, used to convert liquid medication into an inhalable aerosol. The handle and rubber sleeve on top facilitate carrying and prevent slipping. The curved levers are used to secure the air delivery hose. The air outlet assembly is the key structure connecting the nebulizer to the patient's inhalation end. Its air outlet tube, rotating ring, and curved levers together form a quick-connect and lock anti-dislodgement mechanism, designed to solve the problem of accidental tubing dislodgement due to pulling during treatment. At the same time, the combined design of the filter assembly, moving assembly, and squeezing assembly is designed to optimize the air intake filtration effect.

[0006] Furthermore, the air guiding assembly includes an air guiding ring, a retaining ring, a clamping head, an air guiding hose, and a sealing rubber ring. An air guiding ring is fitted onto the right end of the circumferential surface of the air outlet pipe. Two corresponding sealing rubber rings are fixed inside the air guiding ring. Two corresponding annular sealing grooves are formed at the right end of the circumferential surface of the air outlet pipe, and the sealing rubber rings are engaged within the corresponding annular sealing grooves. A retaining ring is fixed to the right end of the surface of the air outlet pipe. Evenly distributed guide holes are formed on the circumferential surface of the retaining ring. A clamping head is engaged inside the guide holes. A clamping hole is formed on the surface of the clamping head, and an arc-shaped clamping rod is engaged within the corresponding clamping hole. All clamping heads are fixed. At the left end of the gas guide ring, a gas guide hose is fixed to the right end inside the gas guide ring. The gas guide hose is snapped between two arc-shaped clips. The core function of the gas guide assembly is to establish a detachable and reliable connection and sealing channel between the gas outlet pipe and the gas guide hose. The cooperation between the sealing rubber ring and the annular sealing groove ensures the airtightness of the connection and prevents drug leakage. The cooperation between the clip head and the guide hole of the clip ring, as well as the engagement of the clip hole on the clip head and the arc-shaped clip rod, together constitute a quick locking mechanism. By rotating the gas guide ring to drive the clip head, the arc-shaped clip rod can be engaged or disengaged from the clip hole, thereby realizing the quick installation, locking and disassembly of the gas guide hose and ensuring the firmness of the connection.

[0007] Furthermore, the filter assembly includes an air intake ring, a first support ring, a rubber mesh ring, a first rubber reinforcing ring, a second rubber reinforcing ring, and medical cotton. An air intake ring is fixed inside the air intake port located at the front of the nebulizer. A first support ring is fixed to the front end of the surface of the air intake ring. A rubber mesh ring is located at the rear end inside the first support ring. A second rubber reinforcing ring is fixed inside the rubber mesh ring. A first rubber reinforcing ring is fixed to the surface of the rubber mesh ring and is fixed inside the first support ring. Medical cotton is evenly distributed at the front end of the rubber mesh ring. The main purpose of the filter assembly is to filter the air entering the nebulizer, removing dust, impurities, and other particulate matter to ensure the purity of the medication and protect the precision components inside the nebulizer. The medical cotton is the main filter medium, located at the front end of the rubber mesh ring. The rubber mesh ring, along with the first and second rubber reinforcing rings, together form an elastic support frame to accommodate and support the medical cotton and ensure its fit with the air intake channel.

[0008] Furthermore, the movable component includes a connecting tube, an externally threaded compression ring, a support plate, and a gauze ring. The front end of the first support ring is threadedly connected to the externally threaded compression ring. The front end of the externally threaded compression ring has an annular vent. The rear end of the annular vent is fixed inside the annular vent. Three corresponding support plates are fixed inside the annular vent. The front end of the externally threaded compression ring is fixed to the connecting tube. By rotating the connecting tube, the externally threaded compression ring moves back and forth within the first support ring. The annular vent and support plate at the front end of the externally threaded compression ring ensure air circulation. The gauze ring, as a pre-filter, can perform preliminary filtration of the air, blocking larger impurities and dispersing airflow. Together with the medical cotton behind it, it forms a multi-stage filtration system.

[0009] Furthermore, the extrusion assembly includes a fixed disc and a conical extrusion column. The fixed disc is fixed to the rear end of the external threaded extrusion ring, and the conical extrusion column is fixed to the rear end of the fixed disc. The conical extrusion column is located inside the medical cotton. The core purpose of the extrusion assembly is to cooperate with the movement of the moving assembly to internally extrude the medical cotton in the filter assembly. When the rotating connecting tube causes the external threaded extrusion ring to be screwed backward, the conical extrusion column fixed to its rear end will move backward synchronously, extruding the medical cotton from the inside, making it more tightly and evenly filled, eliminating gaps that may be caused by manual filling, thereby improving the filtration effect and consistency.

[0010] Furthermore, the front end of the connecting pipe is threaded with an external thread sealing ring, and a sealing cap is fixed to the front end of the external thread sealing ring. The purpose of the sealing cap and the external thread sealing ring is to seal the opening of the connecting pipe when the device is not in use or when there is no need to connect to an external pipe, so as to prevent dust and foreign objects from entering the filter assembly and atomizer, thereby playing a protective and anti-pollution role.

[0011] Furthermore, a second support ring is fixed to the circumferential surface of the first connecting pipe, and a sealing pipe is fixed to the rear end of the second support ring. An annular guide groove is provided at the front end of the first support ring, and the sealing pipe is snapped into the inside of the annular guide groove. The purpose of the second support ring and the sealing pipe is to enhance the stability and sealing of the moving component during operation. The sealing pipe is snapped into the annular guide groove of the first support ring, which can guide the external thread extrusion ring when it rotates and moves, preventing it from swaying. At the same time, this plug-in fit can also form an additional sealing barrier between the first connecting pipe and the air intake ring, preventing unfiltered air from entering from the gap.

[0012] Furthermore, the upper end of the air delivery hose is threaded with a second connecting tube, and the upper end of the second connecting tube is fixed with an inhalation mask. The second connecting tube communicates with the inner cavity of the inhalation mask. The inhalation mask is the part that the patient's mouth and nose directly contact and inhale the medicated mist. The second connecting tube is threaded to the air delivery hose. This design makes it easy to replace the inhalation mask with different specifications or models according to the patient's needs, and also makes it easy to disassemble, clean or disinfect the inhalation mask to maintain hygiene.

[0013] Furthermore, four corresponding casters are installed on the lower side of the nebulizer, and brake plates are installed on the sides of the casters. The purpose of these features is to enhance the portability and stability of the entire device. The four casters allow the device to be easily moved indoors, facilitating treatment for patients in different locations. The brake plates secure the device after it has been moved to the target position, preventing accidental slippage during treatment and ensuring safety and stable treatment.

[0014] Furthermore, a toggle ring is fixed on the circumferential surface of the rotating ring, and a uniformly distributed anti-slip plate is fixed on the circumferential surface of the toggle ring. The anti-slip plate has a uniformly distributed anti-slip groove on its circumferential surface. The toggle ring is fixed on the rotating ring, providing the user with a component specifically for applying force to rotate. The anti-slip plate and anti-slip groove on its circumferential surface significantly increase the friction when the finger contacts the toggle ring, making it easier and more stable for the user to operate the rotating ring to lock or unlock the air guide component, and preventing slippage, thus improving the humanization and convenience of operation.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This portable lung cancer nebulized respiratory therapy device has the following advantages: 1. By setting up an air outlet component and an air guide component, the air guide ring can be rotated during use to drive the clamp head, allowing the arc-shaped clamp rod to engage or disengage from the clamp head's hole, thus achieving quick locking and disassembly of the air guide hose. This effectively prevents the connection from loosening due to accidental pulling of the pipeline, ensuring the continuity of the treatment process and the stability of drug delivery, and improving the safety and reliability of the equipment. 2. By rotating the connecting tube, the conical extrusion column at the rear end can be driven to move inside the medical cotton, thereby uniformly and tightly extruding the filter medium, eliminating the gaps that may be generated by manual filling, thus effectively intercepting impurities in the air and ensuring the cleanliness of the air entering the atomization chamber. This not only protects the purity of the medicine, but also reduces the risk of wear and tear on the precision parts inside the equipment due to dust blockage. 3. The omnidirectional wheels with brake plates facilitate movement and fixation; the actuating ring of the air outlet assembly has an anti-slip structure, making locking operation easier; at the same time, the air intake cover uses a threaded connection for easy replacement and cleaning, and the air inlet is also equipped with a removable sealing cap.

A fixed plate 61 is fixed to the rear end of the fixed plate 61, and the conical extrusion column 62 is fixed to the rear end of the fixed plate 61. The conical extrusion column 62 is located inside the medical cotton 46. The core function of the extrusion assembly 6 is to cooperate with the movement of the moving assembly 5 to internally extrude the medical cotton 46 in the filter assembly 4. When the connecting pipe 51 is rotated to screw the external threaded extrusion ring 52 backward, the conical extrusion column 62 fixed to its rear end moves backward synchronously, extruding pressure on the medical cotton 46 from the inside, making the filling more compact and uniform, eliminating gaps that may occur due to manual filling, thereby improving the filtration effect and consistency. Rotating the connecting pipe 51 drives the external threaded extrusion ring 52 to move back and forth within the first support ring 42. The annular vent at the front end of the pressure ring 52 and the support plate 53 ensure air circulation. The gauze ring 54, as a pre-filter, can perform preliminary filtration of the air, block larger impurities, and disperse the airflow. Together with the medical cotton 46 behind it, it forms a multi-stage filtration system. The main purpose of the filter assembly 4 is to filter the air entering the nebulizer 1 and remove dust, impurities, and other particulate matter to ensure the purity of the medicine and protect the precision components inside the nebulizer. The medical cotton 46 is the main filter medium. It is located at the front end of the rubber mesh ring 43. The rubber mesh ring 43 and the first rubber reinforcing ring 44 and the second rubber reinforcing ring 45 together form an elastic support frame to accommodate and support the medical cotton 46 and ensure its fit with the air intake channel. Air outlet assembly 2 includes an air outlet pipe 21, a fixing ring 22, a rotating ring 23, a torsion spring 24, a connecting plate 25, and an arc-shaped locking rod 26. An air outlet pipe 21 is located on the right side of the atomizer 1. A fixing ring 22 is fixed to the left end of the circumference of the air outlet pipe 21. A rotating ring 23 and a torsion spring 24 are sleeved on the right end of the circumference of the air outlet pipe 21. The left end of the torsion spring 24 is fixed to the right end of the fixing ring 22, and the right end of the torsion spring 24 is fixed to the left end of the rotating ring 23. Evenly distributed connecting plates 25 are fixed to the circumference of the rotating ring 23. An arc-shaped locking rod 26 is fixed to the right end of the connecting plate 25. An air guide assembly 3 is installed on the right end of the surface of the air outlet pipe 21. The air guide assembly 3 connects with all the arc-shaped locking rods. Connected to 26, the air guiding assembly 3 includes an air guiding ring 31, a retaining ring 32, a retaining head 33, an air guiding hose 34, and a sealing rubber ring 35. The air guiding ring 31 is fitted onto the right end of the circumferential surface of the air outlet pipe 21. Two corresponding sealing rubber rings 35 are fixed inside the air guiding ring 31. Two corresponding annular sealing grooves are opened at the right end of the circumferential surface of the air outlet pipe 21, and the sealing rubber rings 35 are engaged inside the corresponding annular sealing grooves. A retaining ring 32 is fixed to the right end of the surface of the air outlet pipe 21. Evenly distributed guide holes are opened on the circumferential surface of the retaining ring 32, and a retaining head 33 is engaged inside the guide holes. A retaining hole is opened on the surface of the retaining head 33, and an arc-shaped retaining rod 26 is engaged inside the corresponding retaining hole. Some of the clamps 33 are fixed to the left end of the gas guide ring 31. A gas guide hose 34 is fixed to the right end inside the gas guide ring 31. The gas guide hose 34 is clamped between two arc-shaped clamps 14. The core function of the gas guide assembly 3 is to establish a detachable and reliable connection and sealing channel between the gas outlet pipe 21 and the gas guide hose 34. The cooperation between the sealing rubber ring 35 and the annular sealing groove ensures the airtightness of the connection, preventing drug leakage. The cooperation between the clamp 33 and the guide hole of the clamp ring 32, and the clamping hole on the clamp 33 and the arc-shaped clamp rod 26, together constitute a quick-locking mechanism. By rotating the gas guide ring 31 to drive the clamp 33, the arc-shaped clamp rod 26 can be clamped into or disengaged from the clamping hole. The quick installation, locking, and removal of the air delivery hose 34 ensures a secure connection. The nebulizer 1 is the core component, used to convert liquid medication into an inhalable aerosol. The handle 17 and rubber sleeve 18 on top facilitate carrying and prevent slipping. The arc-shaped clip 14 is used to secure the air delivery hose. The air outlet assembly 2 is a key structure connecting the nebulizer to the patient's inhalation end. Its air outlet tube 21, rotating ring 23, and arc-shaped clip 26 together form a quick-connect and lock anti-dislodgement mechanism, designed to solve the problem of accidental tubing dislodgement due to pulling during treatment. At the same time, the combined design of the filter assembly 4, moving assembly 5, and squeezing assembly 6 is designed to optimize the air intake filtration effect.

[0020] The connecting pipe 51 has an external threaded sealing ring 8 at its front end. The front end of the external threaded sealing ring 8 is fixed with a sealing cap 7. The purpose of the sealing cap 7 and the external threaded sealing ring 8 is to seal the opening of the connecting pipe 51 when the device is not in use or when there is no need to connect to the external pipeline, so as to prevent dust and foreign objects from entering the filter assembly 4 and the atomizer, thus playing a protective and anti-pollution role.

[0021] The connecting pipe 51 has a second support ring 9 fixed on its circumferential surface. The rear end of the second support ring 9 is fixed with a sealing pipe 10. The front end of the first support ring 42 has an annular guide groove. The sealing pipe 10 is inserted into the annular guide groove. The purpose of the second support ring 9 and the sealing pipe 10 is to enhance the stability and sealing of the moving component 5 during operation. The sealing pipe 10 is inserted into the annular guide groove of the first support ring 42, which can guide the external thread extrusion ring 52 when it rotates and moves, preventing it from swaying. At the same time, this plug-in fit can also form an additional sealing barrier between the connecting pipe 51 and the air intake ring 41 to prevent unfiltered air from entering from the gap.

[0022] The upper end of the air delivery hose 34 is threaded with a connecting tube 12, and the upper end of the connecting tube 12 is fixed with an inhalation mask 13. The connecting tube 12 communicates with the inner cavity of the inhalation mask 13. The inhalation mask 13 is the part that the patient's mouth and nose directly contact and inhale the medicated aerosol. The connecting tube 12 is connected to the air delivery hose 34 by threads. This design makes it easy to replace the inhalation mask 13 with different specifications or models according to the patient's needs, and also makes it easy to disassemble, clean or disinfect the inhalation mask 13 to maintain hygiene.

[0023] The nebulizer 1 has four corresponding casters 15 installed on its lower side. Brake plates 16 are installed on the sides of the casters 15. The purpose of the casters 15 and the brake plates 16 is to enhance the portability and stability of the entire device. The four casters 15 allow the device to be moved easily indoors, making it convenient for patients to receive treatment in different locations. The brake plates 16 can fix the device after it has been moved to the target position, preventing the device from sliding due to accidental contact during treatment, thus ensuring safety and stability of the treatment.

[0024] Among them: a toggle ring 11 is fixed on the circumferential surface of the rotating ring 23, and an anti-slip plate 19 is fixed on the circumferential surface of the toggle ring 11. An anti-slip groove is evenly distributed on the circumferential surface of the anti-slip plate 19. The toggle ring 11 is fixed on the rotating ring 23, providing the user with a component specifically for applying force to rotate. The anti-slip plate 19 and anti-slip groove on its circumferential surface significantly increase the friction when the finger contacts the toggle ring 11, making it easier and more stable for the user to operate the rotating ring 23 to lock or unlock the air guide component 3, and making it less prone to slipping, thus improving the humanization and convenience of operation.

[0025] The working principle of the portable lung cancer nebulized respiratory therapy device provided by this invention is as follows: Before treatment, the air intake filtration system must be ensured to be ready. The operator rotates the connecting tube 51, causing the external threaded compression ring 52 fixed thereto to screw into the first support ring 42. This action simultaneously pushes the conical compression column 62 of the compression assembly 6 fixed to the rear end of the external threaded compression ring 52 to move backward, thereby uniformly compressing the medical cotton 46 placed at the front end of the rubber mesh ring 43 from the inside, making it tightly filled and eliminating gaps. At the same time, the sealing tube 10 moves with the second support ring 9 and is inserted into the annular guide groove of the first support ring 42 to ensure sealing and guidance. Air then enters from the front end of the connecting tube 51, undergoes preliminary filtration through the gauze ring 54, and then flows through the compacted medical cotton 46 for deep filtration. The clean air finally enters the nebulizer 1 through the air intake ring 41. At the inhalation end, the air guide ring 31 at the end of the air guide hose 34 of the air guide assembly 3 is fitted onto the right end of the air outlet tube 21, so that the sealing rubber ring 35 is inserted into the corresponding annular sealing groove. Simultaneously, the clamp at the left end of the air guide ring 31 is inserted into the guide hole opened on the end face of the clamp ring 32. After insertion, the arc-shaped clamp rod 26 is clamped into the clamp hole of the clamp head 33 under the action of the torsion spring 24, achieving quick locking and preventing the air guide hose 34 from accidentally falling off. The air guide hose 34 can be clamped on the arc-shaped clip 14 on the side of the nebulizer 1 to straighten the pipeline. The patient inhales through the inhalation mask 13 connected to the upper end of the air guide hose 34 by threads. During treatment, the nebulizer 1 converts the liquid drug into an aerosol. The drug atomized gas is delivered to the inhalation mask 13 for the patient to inhale through the air outlet pipe 21, the air guide ring 31 and the air guide hose 34. The universal wheels 15 at the bottom of the device are easy to move. After being in place, they can be fixed with the brake plate 16. The handle 17 and rubber sleeve 18 at the top are easy to hold and carry. When not in use, the sealing cap 7 and the external thread sealing ring 8 can be used to seal the opening of the connecting pipe 51. The locking mechanism can be easily rotated by the anti-slip plate 19 on the toggle ring 11.
