Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a respiratory nebulizer therapy device that can prevent reflux. Background Technology

[0002] One of the common clinical treatments for respiratory diseases (such as asthma and chronic bronchitis) is nebulization therapy. Nebulization devices atomize medication into tiny particles, which patients inhale into their respiratory tract and lungs, thereby achieving anti-inflammatory, antitussive, and expectorant effects. During nebulization therapy, patients usually need to wear a mask, which is fixed to the patient's head with a headband or head strap to ensure a close fit to the face and that the nebulized gas can effectively and concentratedly enter the patient's respiratory tract, thus ensuring the treatment effect.

[0003] However, existing respiratory nebulizers still have the following problems in actual use: (1) First, the connection between the mask and the nebulizer tube usually lacks an effective anti-backflow control structure. When the patient exhales, the exhaled waste gas is easy to flow back into the nebulizer tube, which not only causes drug contamination and waste, but also increases the risk of cross-infection; (2) At the same time, the edge sealing of the existing mask is poor, which can easily lead to external air flowing in to dilute the nebulized gas or internal gas leakage, which seriously affects the drug absorption efficiency; (3) In addition, the adjustment method of the headband fixing mechanism of the existing device is relatively simple and cumbersome. It mostly uses simple buckles or hole adjustment, which has low adjustment accuracy and is easy to loosen during the patient's movement. The headband adjustment mechanism is mostly exposed and can easily hook the patient's hair or clothing; (4) The existing device lacks an effective buffer and force distribution design. When the patient wears it for a long time for nebulizer treatment, the head is prone to pressure and discomfort, which significantly reduces the comfort of treatment and the stability of wearing.

[0004] Therefore, the present invention aims to provide a respiratory nebulization therapy device that can prevent reflux, in order to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: including a mask mechanism, an anti-reverse mechanism, a headband mechanism, and a head-mounting mechanism;

[0007] One end of the anti-backflow mechanism is connected to one end of the mask mechanism, and is used for unidirectional introduction of atomized gas and anti-backflow control;

[0008] The headband mechanism and the bandage assembly of the headband mechanism are respectively connected to both sides of the mask mechanism to fix the device to the patient's head;

[0009] The mask mechanism includes an atomizing mask, one end of which is provided with a connection position for the anti-reverse mechanism, and both sides of the atomizing mask are respectively provided with connection positions for the headband mechanism and the headband mechanism;

[0010] The anti-reverse mechanism includes an atomizing corner device and an anti-reverse component disposed inside the atomizing corner device. The anti-reverse component includes a partition baffle, a breathing adjustment rod, and a silicone directional plate. The silicone directional plate deforms under air pressure to control the opening and closing of the air passage.

[0011] The headband mechanism includes a top head cover, a bottom docking shell, and a head docking strap. The head docking strap is connected to the bottom docking shell via an adjustable inner disc, and the head docking strap can be extended and retracted relative to the top head cover.

[0012] The headgear mechanism includes a headgear docking strap and a side rotating disk. One end of the headgear docking strap is connected to the mask mechanism via a docking buckle, and the other end is connected to the side rotating disk.

[0013] In a preferred embodiment, the mask mechanism further includes a smooth cover plate, a silicone guard, connecting bandages, a docking buckle frame, and an atomizing connecting ring;

[0014] The smooth cover plate is fitted onto the sloping surface of the atomizing mask for external protection;

[0015] One end of the silicone guard is attached to the inner surface of the atomizing mask. The silicone guard is used to fit tightly to the patient's face to prevent external air from flowing in and internal atomized gas from flowing out.

[0016] One end of each of the two connecting bandages is respectively attached to both sides of the atomizing mask, and the other end of the connecting bandage is attached to the docking buckle frame, which is located at the end of the atomizing mask away from the atomizing serial ring;

[0017] One end of the atomizing series ring is connected to the atomizing mask, and the atomizing series ring is connected to one end of the atomizing corner device of the anti-reverse mechanism.

[0018] In a preferred embodiment, the anti-reverse mechanism further includes a limiting flap, a side buckle plate, a protective inclined plate, a limiting buckle device, and a docking sleeve;

[0019] The outer surface of the limiting flap is nested in the atomizing corner device, and one end of the atomizing corner device is connected to the atomizing series ring;

[0020] The side buckle plate is attached to the atomizing corner device, and the protective inclined plate is set inside the atomizing corner device to guide and buffer the intake airflow.

[0021] The limiting buckle is fastened to the atomizing corner device and is used to limit the adjustment of the limiting flap;

[0022] The docking sleeve is snapped onto the outer surface of the end of the atomizing corner device away from the atomizing series ring, and the outer surface of the partition baffle is nested in the docking sleeve.

[0023] In a preferred embodiment, the anti-reverse assembly further includes a limiting baffle, a tension spring, and a pneumatic cover plate;

[0024] The outer surface of the breathing adjustment rod is limited to the height adjustment of the partition baffle;

[0025] The limiting baffle is connected to one end of the breathing adjustment rod, and the air pressure cover is connected to the end of the breathing adjustment rod away from the limiting baffle.

[0026] The two ends of the tension spring are respectively connected between the limiting baffle and the partition baffle to provide a restoring force;

[0027] The silicone directional plate is connected to the air pressure cover plate. During the patient's nebulized breathing, the silicone directional plate deforms under the action of air pressure, thereby driving the air pressure cover plate to move.

[0028] As a preferred embodiment, the working principle and structural features of the anti-reverse mechanism are as follows:

[0029] When the patient exhales, the air pressure causes the silicone directional plate to deform downwards, and at the same time, it moves the air pressure cover plate closer to the partition baffle, so that a sealed space is formed inside the docking sleeve to prevent gas backflow.

[0030] When the patient inhales, the negative pressure causes the silicone directional plate to deform upwards, which in turn causes the air pressure cover to adjust upwards and compress the tension spring, thereby allowing the atomized gas to pass through the partition baffle and enter the atomizing mask along the docking sleeve and the atomizing corner device.

[0031] In a preferred embodiment, the headband mechanism further includes a top rotating disk, a mounting cover, a docking bottom shell, a docking chuck, a lower gear disk, a bottom docking shell, and an auxiliary docking belt;

[0032] One end of the auxiliary docking belt is docked to the adjusting inner disc, and the adjusting inner disc is provided with the head docking belt for rotational adjustment;

[0033] The outer surface of the head docking strap is confined within the bottom docking shell and can be adjusted by rotating the top rotating disk on the top head cover;

[0034] The top rotating disk passes through the top cover and mates with the mounting housing, thereby allowing the top rotating disk to drive the mounting housing to rotate within the docking bottom housing via the docking chuck and the lower gear disk.

[0035] As a preferred embodiment, the adjustment and storage structure of the headband mechanism is as follows:

[0036] The outer surface of the docking chuck is nested in the docking bottom shell for damping and snapping adjustment, so that the lower gear disc can drive the head docking band to adjust, thereby retracting the head docking band into the bottom docking shell.

[0037] The top cover snaps onto the bottom docking shell, concealing and storing the mounting cover, the bottom docking shell, the docking chuck, the lower gear plate, and the head docking strap.

[0038] One side of the auxiliary docking strap is attached to one side of the headband docking strap, and the adjusting inner disc is docked to one side of the side rotating disc.

[0039] In a preferred embodiment, the headgear also includes an inner plug plate and an outer rotating shell;

[0040] One end of the auxiliary docking strap and the head-mounted docking strap are nested in the docking buckle and dock with the docking buckle frame of the mask mechanism;

[0041] The end of the headband that is away from the docking buckle is docked to the side rotating disk;

[0042] The adjusting inner disc and the side rotating disc are adjusted by snapping and limiting the position through the inner plug plate and the outer rotating cover.

[0043] In a preferred embodiment, the head-mounted mechanism further includes a left head-mounted adjustment strap, a right head-mounted adjustment strap, a head-mounted frame, an internal pad, an internal retainer, a head-mounted housing, and a mechanical turntable;

[0044] One end of the left headband adjustment strap and the right headband adjustment strap are connected to the headband frame, and their structure is the same as that of the headband mechanism.

[0045] The mechanical turntable rotates within the headgear housing and passes through the headgear housing, engaging with the internal retainer.

[0046] Rotating the mechanical turntable causes the internal housing to rotate, and the damping buckle of the internal pad adjusts the left and right headband adjustment straps so that they can be stored and adjusted in the buckle housing space formed by the headband frame and the headband housing.

[0047] In a preferred embodiment, the head-mounted mechanism further includes a head-mounted cushion;

[0048] The headband cushion is placed on the inner surface of the headband frame to protect and cushion the patient's head.

[0049] The headgear frame and the headgear shell together constitute the main frame of the headgear mechanism. The left and right headgear adjustment straps are infinitely adjustable in length by the drive of the mechanical turntable to accommodate patients with different head circumferences.

[0050] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0051] 1. This invention achieves unidirectional gas induction control by precisely coordinating the mask mechanism and the anti-reverse mechanism, utilizing the air pressure deformation of the silicone directional plate and the reset effect of the tension spring. When the patient inhales, the airway is opened by negative pressure, and when the patient exhales, the airway is closed by positive pressure, effectively preventing the backflow of the patient's exhaled waste gas into the nebulization pipeline, avoiding cross-infection and drug contamination. At the same time, the silicone protective enclosure design ensures facial sealing, greatly improving the safety of nebulization therapy and drug absorption efficiency.

[0052] 2. This invention achieves stepless adjustment and automatic storage of the top headband through the linkage design of the rotating disc, mounting cover, docking chuck, and lower gear disc in the headband mechanism. Patients can precisely adjust the tightness of the headband by simply rotating the top cover through the gear damping structure. The adjustment mechanism can be hidden and stored in the top cover, which not only makes the operation simple and the adjustment accurate, but also avoids external parts from snagging on hair or clothing, thus improving the comfort and overall aesthetics of wearing the headband.

[0053] 3. This invention achieves independent adjustment and storage of the side and rear headbands through the cooperation of the mechanical turntable, internal locking mechanism, and left / right headband adjustment straps in the headband mechanism; combined with the cushioning effect of the headband pad, it can distribute the wearing pressure according to the patient's head shape, ensuring that the mask fits the face tightly without causing pressure, solving the problem of cumbersome adjustment and easy loosening of traditional headbands, and significantly improving the wearing stability and comfort during long-term nebulization treatment.

[0073] The present invention will now describe a respiratory nebulization therapy device that can prevent reflux.

[0074] Example 1

[0075] like Figure 1-8 As shown, the present invention provides a technical solution: a respiratory nebulization therapy device with anti-reflux function, comprising a mask mechanism 1, an anti-reflux mechanism 2, a headband mechanism 3, and a headband mechanism 4;

[0076] One end of the anti-backflow mechanism 2 is connected to one end of the mask mechanism 1, and is used for unidirectional introduction of atomizing gas and anti-backflow control;

[0077] The bandage assemblies of the headband mechanism 3 and the headband mechanism 4 are respectively connected to both sides of the mask mechanism 1 to fix the device to the patient's head;

[0078] The mask mechanism 1 includes an atomizing mask 11, one end of which is provided with a connection position for an anti-reverse mechanism 2, and the two sides of the atomizing mask 11 are respectively provided with connection positions for a headband mechanism 3 and a headband mechanism 4;

[0079] The anti-reverse mechanism 2 includes an atomizing corner device 21 and an anti-reverse component disposed inside the atomizing corner device 21. The anti-reverse component includes a partition baffle 27, a breathing adjustment rod 28, and a silicone directional plate 212. The silicone directional plate 212 deforms under air pressure to control the opening and closing of the air passage.

[0080] The headband mechanism 3 includes a top head cover 31, a bottom docking shell 37, and a head docking strap 38. The head docking strap 38 is connected to the bottom docking shell 37 through an adjusting inner disc 39, and the head docking strap 38 can be extended and retracted relative to the top head cover 31.

[0081] The head-mounted mechanism 4 includes a head-mounted docking strap 41 and a side rotating disk 43. One end of the head-mounted docking strap 41 is connected to the mask mechanism 1 through a docking buckle 42, and the other end is connected to the side rotating disk 43.

[0082] The mask mechanism 1 also includes a smooth cover plate 12, a silicone guard 13, a connecting bandage 14, a docking buckle frame 15, and an atomizing series ring 16;

[0083] The smooth cover plate 12 is fitted onto the sloping sliding surface of the atomizing mask 11 for external protection;

[0084] One end of the silicone guard 13 is attached to the inner surface of the atomizing mask 11. The silicone guard 13 is used to fit tightly to the patient's face to prevent external air from flowing in and internal atomized gas from flowing out.

[0085] One end of each of the two connecting bandages 14 is connected to both sides of the atomizing mask 11, and the other end of the connecting bandages 14 is connected to the docking buckle frame 15. The docking buckle frame 15 is located at the end of the atomizing mask 11 away from the atomizing serial ring 16.

[0086] One end of the atomizing series ring 16 is connected to the atomizing mask 11, and the atomizing series ring 16 is connected to one end of the atomizing corner device 21 of the anti-reverse mechanism 2;

[0087] The anti-reverse mechanism 2 also includes a limit flap 22, a side buckle plate 23, a protective inclined plate 24, a limit buckle device 25, and a docking sleeve 26;

[0088] The outer surface of the limiting flap 22 is nested in the atomizing corner device 21, and one end of the atomizing corner device 21 is connected to the atomizing series ring 16;

[0089] The side buckle plate 23 is connected to the atomizing corner device 21, and the protective inclined plate 24 is set inside the atomizing corner device 21 to guide and buffer the airflow.

[0090] The limit latch 25 is latched onto the atomizing corner device 21 and is used to limit the adjustment of the limit flap 22;

[0091] The docking sleeve 26 is snapped onto the outer surface of the end of the atomizing corner device 21 away from the atomizing series ring 16, and the outer surface of the partition baffle 27 is nested in the docking sleeve 26;

[0092] The anti-reverse assembly also includes a limit baffle 29, a tension spring 210, and a pneumatic cover 211;

[0093] The outer surface of the breathing adjustment rod 28 is limited by the partition baffle 27 for height adjustment;

[0094] The limiting baffle 29 is connected to one end of the breathing adjustment rod 28, and the air pressure cover 211 is connected to the end of the breathing adjustment rod 28 away from the limiting baffle 29;

[0095] The two ends of the tension spring 210 are respectively connected between the limiting baffle 29 and the partition baffle 27 to provide a restoring force;

[0096] The silicone directional plate 212 is attached to the air pressure cover plate 211. During the patient's nebulized breathing, the silicone directional plate 212 deforms under the action of air pressure, thereby driving the air pressure cover plate 211 to move.

[0097] The working principle and structural features of the anti-reverse mechanism 2 are as follows:

[0098] When the patient exhales, the air pressure causes the silicone directional plate 212 to deform downwards, and at the same time, it moves the air pressure cover plate 211 closer to the partition baffle 27, so that a sealed space is formed inside the docking sleeve 26 to prevent gas backflow.

[0099] When the patient inhales, the negative pressure causes the silicone directional plate 212 to deform upward, which in turn causes the air pressure cover plate 211 to adjust upward and compress the tension spring 210, thereby allowing the atomized gas to pass through the partition baffle 27 and enter the atomized mask 11 along the docking sleeve 26 and the atomizing corner device 21.

[0100] In this embodiment, through the precise cooperation between the mask mechanism 1 and the anti-reverse mechanism 2, the deformation caused by the air pressure of the silicone directional plate 212 and the reset effect of the tension spring 210 are used to achieve unidirectional control of the introduction of atomized gas. When the patient inhales, the airway is opened by negative pressure and closed by positive pressure when exhaling, which effectively prevents the waste gas exhaled by the patient from flowing back into the atomization pipeline, avoiding cross-infection and drug contamination. At the same time, the design of the silicone protective barrier 13 ensures facial sealing, which greatly improves the safety of atomization therapy and the efficiency of drug absorption.

[0101] Example 2

[0102] like Figure 1-6 As shown, the headband mechanism 3 also includes a top rotating disk 32, a mounting cover 33, a docking bottom shell 34, a docking chuck 35, a lower gear disk 36, a bottom docking shell 37, and an auxiliary docking belt 310;

[0103] One end of the auxiliary docking belt 310 is docked to the adjusting inner disc 39, and the adjusting inner disc 39 is provided with a head docking belt 38 for rotational adjustment.

[0104] The outer surface of the head docking strap 38 is limited in the bottom docking shell 37 and is adjusted by rotating the top rotating disk 32 on the top head cover 31.

[0105] The top rotating disk 32 passes through the top cover 31 and docks with the mounting cover 33, so that the top rotating disk 32 can drive the mounting cover 33 to rotate in the docking bottom shell 34 through the docking chuck 35 and the lower gear disk 36.

[0106] The adjustment and storage structure of the headband mechanism 3 is as follows:

[0107] The outer surface of the docking chuck 35 is nested in the docking bottom shell 34 for damping and buckling adjustment, so that the lower gear 36 can drive the head docking belt 38 to adjust, thereby retracting the head docking belt 38 into the bottom docking shell 37.

[0108] The top cover 31 is snapped onto the bottom docking shell 37, concealing and storing the mounting cover 33, docking bottom shell 34, docking chuck 35, lower gear plate 36, and head docking strap 38.

[0109] One side of the auxiliary docking strap 310 is attached to one side of the head-mounted docking strap 41, and the adjusting inner disc 39 is docked to one side of the side rotating disc 43.

[0110] In this embodiment, the stepless adjustment and automatic storage function of the top headband is realized through the linkage design of the top rotating disk 32, the mounting cover 33, the docking chuck 35 and the lower gear disk 36 in the headband mechanism 3. The patient only needs to rotate the top head cover 31 to accurately adjust the tightness of the head docking strap 38 through the gear damping structure. Moreover, the adjustment mechanism can be hidden and stored by the top head cover 31. It is not only easy to operate and has high adjustment accuracy, but also avoids external parts from snagging on hair or clothing, thus improving the wearing comfort and overall aesthetics.

[0111] Example 3

[0112] like Figure 1-8 As shown, the head-mounted mechanism 4 also includes an inner plug plate 44 and an outer rotating shell 45;

[0113] One end of the auxiliary docking strap 310 and the head-mounted docking strap 41 are nested in the docking buckle 42 and dock with the docking buckle frame 15 of the mask mechanism 1;

[0114] The end of the headband 41 away from the docking buckle 42 is docked to the side rotating disk 43;

[0115] The inner disc 39 and the side rotating disc 43 are adjusted by snap-fit ​​limiting through the inner plug plate 44 and the outer rotating cover 45;

[0116] The head-mounted mechanism 4 also includes a left head-mounted adjustment strap 46, a right head-mounted adjustment strap 47, a head-mounted frame 48, an internal pad 49, an internal retainer 410, a head-mounted cover 411, and a mechanical turntable 412.

[0117] One end of the left headband adjustment strap 46 and the right headband adjustment strap 47 are connected in the headband frame 48, and their structure is the same as that of the headband mechanism 3.

[0118] The mechanical turntable 412 rotates within the headgear 411 and passes through the headgear 411 to engage with the internal retainer 410.

[0119] Rotating the mechanical turntable 412 drives the internal retainer 410 to rotate, and through the damping buckle of the internal pad 49, the left headband adjustment strap 46 and the right headband adjustment strap 47 can be stored and adjusted within the buckle cover space formed by the headband frame 48 and the headband cover 411.

[0120] The head-mounted mechanism 4 also includes a head-mounted cushion 413;

[0121] The headband cushion 413 is placed on the inner surface of the headband frame 48 to protect and cushion the patient's head;

[0122] The headgear frame 48 and the headgear shell 411 together constitute the main frame of the headgear mechanism 4. The left headgear adjustment strap 46 and the right headgear adjustment strap 47 are infinitely adjustable in length by the drive of the mechanical turntable 412 to accommodate patients with different head circumferences.

[0123] In this embodiment, the independent adjustment and storage of the side and rear headbands are achieved through the cooperation of the mechanical turntable 412, the internal locking case 410, and the left headband adjustment strap 46 / right headband adjustment strap 47 in the headband mechanism 4. With the cushioning effect of the headband cushion 413, the wearing pressure can be distributed according to the patient's head shape, ensuring that the mask fits the face tightly without causing pressure. This solves the problem of traditional headband adjustment being cumbersome and easy to loosen, and significantly improves the wearing stability and comfort during long-term nebulization treatment.

[0124] Working principle:

[0125] like Figure 1-8 As shown, in actual use, the patient fits the mask mechanism 1 against their face, using the silicone guard 13 to tightly contact the skin to prevent external air from flowing in and internal atomized gas from flowing out. Then, the headband is adjusted by rotating the top rotating disk 32 on the top of the headband mechanism 3, which drives the mounting shell 33 to rotate in the docking bottom shell 34. Using the damping buckle action of the docking chuck 35 and the lower gear disk 36, the head docking strap 38 is driven to extend and retract in the bottom docking shell 37 to adapt to the curvature of the head. Rotating the mechanical turntable 412 on the side of the headwear mechanism 4 drives the internal chuck 410 to rotate, and through the damping adjustment of the internal pad 49, the left headwear adjustment strap 46 and the right headwear adjustment strap 47 are lengthened in the space between the headwear frame 48 and the headwear shell 411. Finally, the headband mechanism 3, the headwear mechanism 4 and the mask mechanism 1 are firmly connected by the docking buckle 42 and the docking buckle frame 15, achieving a comfortable fixation of the device.

[0126] When the patient inhales, a negative pressure environment is generated inside the mask mechanism 1. This negative pressure acts on the silicone adjusting plate 212 in the anti-reverse mechanism 2, causing it to deform upwards. This, in turn, drives the air pressure cover plate 211 to move upwards and compress the tension spring 210. An air passage is formed between the partition baffle 27 and the air pressure cover plate 211. External atomized gas passes through the partition baffle 27 and enters the atomizing mask 11 along the docking sleeve 26 and the atomizing corner device 21. The protective inclined plate 24 guides and buffers the airflow to ensure that the airflow enters the patient's respiratory tract smoothly, providing the patient with effective atomization treatment.

[0127] When the patient exhales, the exhaled airflow generates positive pressure within the mask mechanism 1. This pressure acts on the silicone directional plate 212, causing it to deform downwards. This causes the pressure cover plate 211 to move downwards and approach the partition baffle 27, forming a sealed space inside the connecting sleeve 26. This blocks the backflow path of gas towards the nebulizer tube. The exhaled gas is confined within the mask or discharged through structures such as the limiting flap 22, thus achieving the anti-backflow function, ensuring the hygiene of the nebulization environment, and preventing waste of medication and contamination of the tubing.
