Abstract

This invention relates to the technical field of medical devices and discloses a multifunctional sputum expectoration machine, including a body and a vest, and further including multiple flow-blocking components located inside the vest, two flexible frames fixedly connected inside the vest, and a diversion tube connected between the two flow-blocking components. Each flow-blocking component includes a frame shell fixedly connected to the flexible frame, and a force-bearing component including a set position and an initial position. When the force-bearing component moves from the initial position to the set position, it interconnects two adjacent independent spaces inside the frame shell, thereby generating a gradual, moving impact of airflow. By connecting the two flow-blocking components through a single flexible frame, and with the two flow-blocking components sharing a single diversion tube for air delivery, the two flow-blocking components can respectively correspond to different areas of the chest wall. This allows different chest wall areas to receive differentiated impacts according to the stage of sputum migration, forming a dynamic, following mechanical traction, preventing sputum from redepositing during migration, achieving a cyclical gradient impact, and avoiding continuous uniform pressure damage to cilia.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a multifunctional sputum excretion machine. BACKGROUND

[0002] The sputum excretion instrument, also known as a pneumatic high-frequency oscillation sputum excretion system or a multifunctional extracorporeal vibration sputum excretion machine, is an innovative medical device that utilizes pneumatic power technology. The main machine generates a waveband frequency oscillation type of compressed air, which is transmitted to a specially designed air bag vest through a pipeline. The vest performs a regular cycle of inflation, compression, and relaxation on the chest wall. The resulting vibration waves can loosen and dilute the thick secretions in the respiratory tract, activate the cilia on the airway wall, and guide the sputum to migrate upwards in the respiratory tract. Ultimately, the sputum is excreted through coughing or swallowing action.

[0003] However, the conventional air bag vest in the prior art adopts a whole air bag chamber, i.e., only one or two large-area connected air bag regions are provided inside the vest. When inflated, the entire chest wall is simultaneously subjected to force, and the impact energy is uniformly dispersed in all areas such as the front, back, and sides of the chest. As a result, all areas can only obtain an average impact force, forming a situation of overall coverage but overall inefficiency. For stubborn sputum that accumulates locally, it is completely impossible to form an effective impact effect, making it difficult to push it away from the airway wall. In terms of impact mode, the working cycle of the conventional air bag vest is only a single process of inflation and compression, lacking a phased pressure gradient and frequency change, and unable to form an effective and sustained mechanical traction. Even if the sputum is temporarily loosened, it is difficult to obtain a stable migration driving force, and it is unable to form a sustained migration trend. Furthermore, the migration of sputum from the deep part of the airway to the throat is a dynamic process that requires different stages of impact on different areas. However, the fixed impact mode cannot achieve this dynamic adaptation, and the same way of acting on the entire chest wall always results in a lack of sustained mechanical pushing during the migration process, often causing re-deposition in the middle of the way and failing to be smoothly excreted outside the body. At the same time, the sustained uniform pressure can inhibit the amplitude of cilia movement, and even cause fatigue damage to some cilia, resulting in a loss of movement ability. This makes the physiological sputum excretion function of the airway weakened, and the sputum that can be excreted through cilia movement becomes more difficult to excrete due to the impairment of cilia function, thereby weakening the sputum excretion function of the airway itself, forming a problem of conflict between mechanical impact and physiological sputum excretion. It is neither able to form a locally focused strong impact force nor lacks a sequential and progressive phased action, making it difficult for the pneumatic power technology advantage of the sputum excretion instrument to be fully utilized.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objectives, characteristics and advantages of the present application more apparent, a detailed description of the specific embodiments of the present application will be given below with reference to the accompanying drawings.

[0033] REFERENCE Figures 1-10 For the embodiments of the present application, a multifunctional sputum excretion machine is provided, which comprises a body 1 and a back 2, further comprises a plurality of flow separation assemblies 01 arranged inside the back 2, two soft frames 3 fixedly connected inside the back 2, and a shunt pipe 4 connected between the two flow separation assemblies 01.

[0034] The flow separation assembly 01 comprises a frame shell 5 fixedly connected with the soft frame 3, an air guide pipe 6 fixedly connected inside the frame shell 5, a plurality of force receiving members 7 equidistantly arranged and slidably connected with the frame shell 5, a plurality of arc pieces 8 equidistantly arranged and rotatably connected outside the air guide pipe 6, a pull-back member 9 arranged inside the frame shell 5, a plurality of connecting pipes 10 equidistantly arranged and clamped inside the frame shell 5, and a plurality of sealing plates 11 equidistantly arranged and fixedly connected with the force receiving members 7. The shunt pipe 4 is connected with the two air guide pipes 6, the arc pieces 8 are connected with the force receiving members 7, the inside of the frame shell 5 is divided into a plurality of independent spaces, the plurality of force receiving members 7 are respectively located in different independent spaces, the force receiving members 7 comprise a set position and an initial position, and when the force receiving members 7 move from the initial position to the set position, the frame shell 5 communicates the corresponding adjacent two independent spaces inside to generate a step-by-step moving impact on the airflow.

[0035] In addition, the single soft frame 3 is connected with the two flow separation assemblies 01, and the two flow separation assemblies 01 convey air through the single shunt pipe 4.

[0036] Wherein, the number of force receiving members 7 can be three, when the first force receiving member 7 is impacted by the airflow to move upwards, the force receiving member 7 moves from the initial position to the set position, so that the first independent space and the second independent space are communicated, and the last independent space is only communicated with the previous independent space, therefore, the number of independent spaces in the frame shell 5 can be four, so that the airflow first impacts the first independent space, then simultaneously impacts the first and second independent spaces, gradually increases, and when impacting the last independent space, all force receiving members 7 are moved downwards by the pull-back member 9, and all force receiving members 7 return to the initial position, and the step-by-step moving impact is restarted.

[0037] Specifically, the frame shell 5 is divided into four independent spaces, and three slidable force receiving members 7 are arranged, so that when the airflow enters the frame shell 5 through the air guide pipe 6, the first force receiving member 7 is impacted by the airflow to move from the initial position to the set position, so that the first independent space and the second independent space are communicated, at this time, the impact energy is concentrated on the chest wall area corresponding to the first two independent spaces, forming a local strong impact, and as the airflow continues to input, the subsequent force receiving members 7 are sequentially displaced, gradually opening the second to third and third to fourth independent spaces, which not only ensures that the impact energy is not dispersed, but also can accurately apply force to the sputum in different chest wall areas, solves the problem of traditional equipment that covers all areas but is inefficient, and makes the stubborn sputum accumulated in the local area be effectively loosened and separated from the airway wall, realizes the chest wall partition adaptation, and replaces the traditional fixed impact mode, when the three force receiving members 7 are sequentially displaced to the set position and complete the impact of the full communication of the four independent spaces, the pull-back member 9 drives all force receiving members 7 to move downwards to the initial position synchronously, and the step-by-step impact process of the first independent space→the second independent space→the third independent space→the fourth independent space is restarted, so that each area of the chest wall will not bear continuous pressure, the pressure gradually increases during impact, and the pressure is released temporarily during reset, which not only ensures the continuous mechanical pushing required for sputum migration, but also avoids the cilia being pressed for a long time, protects the physiological sputum excretion function of the airway itself, and accurately delivers the oscillating compressed air to the flow separation assembly 01 in the vest 2 through the shunt pipe 4, the four independent spaces of the frame shell 5 are matched by the connecting pipe 10 and the sealing plate 11, so that the airflow does not leak and the impact direction does not deviate, which makes the sputum excretion process more efficient and more in line with human physiological laws.

[0038] With reference to Figures 2-7 , the air guide pipe 6 is divided into a segmented air pipe 61 and a one-way air pipe 62, both of which are fixedly connected inside the frame shell 5, the arc piece 8 is rotatably connected outside the segmented air pipe 61, the connecting pipe 10 is connected with the port of the segmented air pipe 61, the number of the segmented air pipe 61, the force receiving member 7, the arc piece 8 and the connecting pipe 10 is equal, the pull-back member 9 is connected with the one-way air pipe 62, the one-way air pipe 62 is located in the last independent space, and the number of the segmented air pipe 61 is three, which are located in different independent spaces, when the airflow generates impact, the force receiving member 7 moves, and then the arc piece 8 changes the exhaust position of the segmented air pipe 61.

[0039] Specifically, the design of three segmented air tubes 61 independently conveying allows the airflow intensity and exhaust direction of each independent space to be flexibly adjusted through the arc piece 8. For the independent space where the stubborn sputum is located, the airflow can be concentrated through the segmented air tube 61 to improve the loosening efficiency of stubborn sputum. The cooperation of the one-way air tube 62 and the pull-back piece 9 can assist the pull-back piece 9 to work only by controlling the airflow of the one-way air tube 62, thereby reducing the mechanical failure points of the equipment and the frequency of adjusting the equipment by medical staff. The clamping cooperation of the connecting pipe 10 and the segmented air tube 61 allows the airflow to be output from the segmented air tube 61, guided through the connecting pipe 10, and adjusted through the whole process of the force receiving piece 7 and the arc piece 8 without leakage and blockage. After the airflow enters the frame shell 5, it will be directly conveyed to the corresponding independent space through the segmented air tube 61, avoiding the problem of airflow diffusion across the independent space in the traditional whole air guide pipe 6. At the same time, the clamping of the connecting pipe 10 and the segmented air tube 61 port can tightly seal the airflow channel to ensure that the impact airflow of each independent space does not leak, further strengthening the local impact intensity. When the force receiving piece 7 is moved by the airflow impact, the arc piece 8 will rotate with the force receiving piece 7 to change the exhaust position of the segmented air tube 61, guiding the airflow to act on two independent spaces synchronously to realize the transition of step-by-step expansion impact and avoid the impact rhythm interruption caused by airflow direction disorder.

[0040] When the impact enters the last independent space, i.e., completes the full coverage of the four independent spaces, the pull-back piece 9 needs to drive the three force receiving pieces 7 to reset synchronously. At this time, the one-way air tube 62 can direct the auxiliary airflow through the connection with the pull-back piece 9 to provide stable power for the pull-back piece 9, ensuring that the three force receiving pieces 7 are synchronously lowered to the initial position to ensure the smoothness of the impact and reset cycle.

[0041] Referring to Figures 2-7 , the top and bottom of the segmented air tube 61 are provided with arc grooves 601, and the bottom of the one-way air tube 62 is provided with an arc groove 601. When the force receiving piece 7 is at the initial position, the arc piece 8 only closes the arc groove 601 at the bottom of the segmented air tube 61. At this time, the airflow will only be discharged from the top arc groove 601, thereby impacting the force receiving piece 7 to make the force receiving piece 7 move. When the force receiving piece 7 is at the set position, the arc piece 8 only closes the arc groove 601 at the top of the segmented air tube 61. At this time, the airflow will be discharged from the bottom arc groove 601, and at the same time, the force receiving piece 7 of the next independent space will be impacted.

[0042] Among them, the top arc groove 601 represents the back of the back 2, and the bottom arc groove 601 represents the front of the back 2. The airflow discharged from the bottom arc groove 601 will directly impact the patient.

[0043] Specifically, the airflow of the top arc slot 601 does not directly act on the patient's chest wall, but impacts the back of the force receiving member 7, pushing the force receiving member 7 to move from the initial position to the set position, ensuring that the force receiving member 7 can be stably displaced to the target position. The airflow of the first segmented air pipe 61 first pushes the first force receiving member 7, and on the one hand, the airflow of the bottom arc slot 601 directly impacts the patient's chest wall in the corresponding independent space. Because the airflow is directed and does not spread across the independent space, it can form a strong impact focused on a local area, effectively loosening the sputum in that area. On the other hand, part of the airflow will naturally act on the force receiving member 7 of the next independent space, such as the bottom airflow of the first segmented air pipe 61, which can assist in pushing the second force receiving member 7 to move to the set position, realizing the synchronization of the impact on the patient in the current independent space and the driving of the component in the next independent space. The impact and pushing process of the three segmented air pipes 61 seamlessly connects, that is, the gradual impact logic from the first independent space to the first and second independent spaces, avoiding interruption of the impact between stages, allowing each stage of the gradual impact to be seamlessly connected without gaps. Sputum is continuously mechanically pushed during migration and does not re-deposit due to stage interruption. At the same time, sudden airflow impact on the chest wall is reduced, reducing patient discomfort, especially for elderly or postoperative patients with lower tolerance.

[0044] Referring to Figures 3-10 The force receiving member 7 includes a pneumatic plate 71 arranged above the air guide pipe 6, a vertical rod 72 and a transmission rod 73 fixedly connected with the pneumatic plate 71, and a reset spring 74 connected between the vertical rod 72 and the frame shell 5. The transmission rod 73 is provided with a thin shaft 731, the outer portion of the arc piece 8 is fixedly connected with a slot rod 81, and the slot rod 81 is in sliding connection with the thin shaft 731. When the transmission rod 73 moves upward with the pneumatic plate 71, the thin shaft 731 is pulled, which in turn pulls the slot rod 81 to rotate the arc piece 8, thereby closing different arc slots 601 and opening another arc slot 601. The top surface of the pneumatic plate 71 is provided with a circular groove 711, and the top surface of the pneumatic plate 71 is fixedly connected with a lower magnetic strip 701.

[0045] The inside of the frame shell 5 is provided with a plurality of upper magnetic strips 501, and the upper magnetic strips 501 are attracted to the lower magnetic strip 701 when the pneumatic plate 71 is in the set position. The attraction force of the upper magnetic strips 501 and the lower magnetic strip 701 is greater than the maximum return force of the reset spring 74, so that when the upper magnetic strips 501 and the lower magnetic strip 701 are attracted, the independent space will always be in a communication state, avoiding automatic closure of the independent space.

[0046] In addition, the lower portion of the pneumatic plate 71 is provided with a soft sheet to reduce the overall weight and better respond to airflow impact and movement, improving the response sensitivity to airflow.

[0047] Specifically, when the airflow is discharged from the top arc slot 601 of the segmented air pipe 61, the airflow can easily push the pneumatic plate 71 to move upwards, ensuring efficient transmission and starting. When the pneumatic plate 71 moves upwards with the airflow, the transmission rod 73 moves upwards synchronously, driving the thin shaft 731 to slide in the slot rod 81. Due to the angle limitation of the rotation connection between the arc piece 8 and the segmented air pipe 61, the sliding of the thin shaft 731 will be converted into a pulling force on the slot rod 81, forcing the arc piece 8 to rotate around the segmented air pipe 61, closing one arc slot 601 and opening another arc slot 601 for switching. The vertical rod 72 and the reset spring 74 limit the reset and movement to ensure the linear movement of the pneumatic plate 71. When the pull-back piece 9 starts the reset process, the elastic force of the reset spring 74 can assist in pulling the pneumatic plate 71 downwards, driving the transmission rod 73 and the thin shaft 731 to reset synchronously, and then rotating the arc piece 8 back to the initial angle, preparing for the next round of impact and switching cycle, avoiding slow reset caused by the weight of the components. The lower magnetic strip 701 and the upper magnetic strip 501 can lock the set position of the pneumatic plate 71, ensuring continuous communication between independent spaces. Each force receiving piece 7 is locked by a magnetic strip after reaching the position, ensuring that the independent spaces that have been communicated remain connected, and the newly impacted independent space can be stacked on top, avoiding the problem of repeated switching of impact areas and interruption of sputum migration in traditional equipment, allowing sputum to obtain stable thrust in a continuously expanding impact area.

[0048] When the force receiving piece 7 is stable at the set position, the bottom arc slot 601 of the segmented air pipe 61 remains open, corresponding to the continuous communication of independent spaces, such as the first and second independent spaces, which will not be closed due to the elastic force of the reset spring 74 or airflow fluctuations causing the force receiving piece 7 to move downwards unexpectedly. Figures 2-6 The inside of the frame shell 5 is provided with a slope plate 51 and a partition plate 52. The slope plate 51 separates the upper and lower areas inside the frame shell 5, so that when the airflow is discharged from the top arc slot 601, it only impacts the pneumatic plate 71 and cannot impact the lower part. The partition plate 52 divides the inside of the frame shell 5 into multiple independent spaces.

[0049] Referring to Figures 2-8 The pull-back piece 9 includes a sliding rod 91 slidingly connected inside the one-way air pipe 62, a return spring 92 sleeved outside the sliding rod 91, a circular shaft 93 fixedly connected to the top end of the sliding rod 91, and a thin piece 94 fixedly connected to the bottom end of the sliding rod 91. The circular shaft 93 is located directly above the circular groove 711 and has the same diameter as the circular groove 711. The length of the circular shaft 93 is equal to that of the air guide pipe 6. The return spring 92 is located between the upper part of the sliding rod 91 and the one-way air pipe 62.

[0050] Specifically, when the last independent space completes the impact, at this time all the force members 7 are in the set position, so half of the circular shaft 93 is located inside the circular groove 711, which can also be understood that the circular shaft 93 is located between the upper magnetic strip 501 and the lower magnetic strip 701. When the air flow pressure in the one-way air pipe 62 increases, it pushes the thin sheet 94 to move downward, and the thin sheet 94 drives the sliding rod 91 to move, while compressing the return spring 92, thereby making the circular shaft 93 move downward, separating the upper magnetic strip 501 and the lower magnetic strip 701, reducing the magnetic force of the two. After the force of the pull force is superimposed on the elastic force of the return spring 74, it is greater than the adsorption force of the upper magnetic strip 501 and the lower magnetic strip 701, forcing the pneumatic plate 71 to move downward, synchronously driving the vertical rod 72 and the transmission rod 73 to move downward, so that the force member 7 returns to the initial position from the set position. When the force member 7 is reset, the contraction force of the return spring 92 pulls the sliding rod 91 to move back, preparing for the next reset action, ensuring that all force members 7 are reset synchronously, and ensuring that the cycle of gradual impact, synchronous reset, and gradual impact is not interrupted.

[0051] With reference to Figures 3-9 , the arc of the arc slot 601 is ninety degrees, and the angle between the slot rod 81 and the upper inclined plate 51 is ninety degrees when the force member 7 is in the initial position. The inclined plate 51 is fixedly connected with a vertical pipe 511, and the vertical rod 72 is slidingly connected in the vertical pipe 511.

[0052] Specifically, when the force member 7 moves from the initial position to the set position, the transmission rod 73 drives the slot rod 81 to pull the arc piece 8 to rotate ninety degrees, which can completely cover the ninety-degree arc of the arc slot 601. Neither will it cause incomplete sealing due to insufficient arc, nor will it cause overtravel of the arc piece 8 to interfere with adjacent components due to excessive arc, ensuring that the air flow pushes the pneumatic plate 71 when it is discharged at the top, and impacts the chest wall when it is discharged at the bottom. Two directional paths are switched to avoid air flow turbulence and loss.

[0053] With reference to Figures 1-10 , the vest 2 is fixedly connected with an air inlet pipe 21, one end of the air inlet pipe 21 is connected with the body 1, and the other end of the air inlet pipe 21 is connected with the shunt pipe 4. The shunt pipe 4 is provided with a gas hole 41, and the air flow enters the inside of the vest 2 through the gas hole 41, and the shunt pipe 4 directly delivers the air flow to the first segmented air pipe 61. The air flow in the body 1 enters the shunt pipe 4 through the air inlet pipe 21, and the shunt pipe 4 disperses the air flow into the vest 2 and the air guide pipe 6.

[0054] With reference to Figures 1-10A torsion spring 101 is connected between the connecting pipe 10 and the air guide pipe 6, which ensures that the arc piece 8 can be effectively reset even if the slot rod 81 and the thin shaft 731 are worn out. A through slot 102 is formed in the connecting pipe 10, and the sealing plate 11 penetrates the through slot 102. Adjacent segmented air pipes 61 are communicated through the connecting pipe 10, and the sealing plate 11 is used to seal the connecting pipe 10. When the pneumatic plate 71 moves upwards to drive the sealing plate 11, the sealing plate 11 opens the connecting pipe 10, and the two different independent spaces of the segmented air pipes 61 are communicated.

[0055] Specifically, the sealing plate 11 completely penetrates the through slot 102 of the connecting pipe 10, and seals the passage between adjacent segmented air pipes 61. At this time, each segmented air pipe 61 corresponds to its own independent space. When the airflow is discharged from the top arc slot 601, it only acts on the pneumatic plate 71 of the current independent space, ensuring that the logic of initially pushing the single force piece 7 to be impacted. When the pneumatic plate 71 moves upwards, the sealing plate 11 moves upwards along the through slot 102, and the sealing plate 11 gradually withdraws from the inside of the connecting pipe 10. The passage of adjacent segmented air pipes 61 is opened, and the first and second segmented air pipes 61 are communicated through the connecting pipe 10. The airflow can enter two independent spaces at the same time, forming a gradual impact rhythm.

[0056] The working principle of the present application is as follows: the oscillating compressed air generated by the body 1 is delivered to the shunt pipe 4 through the inlet pipe 21, the shunt pipe 4 on the one hand delivers air to the inside of the vest 2 through the air hole 41, and on the other hand directly guides the airflow to the first segmented air pipe 61, at this time, the airflow is discharged from the top arc slot 601 of the first segmented air pipe 61 and only impacts the back of the first pneumatic plate 71, pushing the first pneumatic plate 71 to move upwards, when the pneumatic plate 71 moves upwards, it synchronously drives the vertical rod 72, the transmission rod 73 and the sealing plate 11 to move upwards, the vertical rod 72 slides linearly along the vertical pipe 511 and stretches the reset spring 74, when the transmission rod 73 moves upwards, the thin shaft 731 at the end of the transmission rod 73 slides in the slot rod 81 of the arc piece 8, at the same time, it generates an upward extrusion force in the slot rod 81, because the arc piece 8 is rotationally connected with the segmented air pipe 61 and is limited, it drives the arc piece 8 to rotate by ninety degrees, in turn, it closes the top arc slot 601 and opens the bottom arc slot 601; the sealing plate 11 moves upwards along the through slot 102 and gradually withdraws from the connecting pipe 10, so that the first and second segmented air pipes 61 communicate with each other through the connecting pipe 10, at this time, the airflow discharged from the bottom arc slot 601 directly impacts the corresponding chest wall area, and part of the airflow assists in pushing the next pneumatic plate 71, when the pneumatic plate 71 moves to the set position, the lower magnetic strip 701 on the top surface of the pneumatic plate 71 is adsorbed and locked with the upper magnetic strip 501 in the frame shell 5, the adsorption force is greater than the elastic force of the reset spring 74, which ensures that the independent spaces that have been communicated always remain connected, with the continuous input of the airflow, the subsequent force receiving member 7 repeats the above-mentioned action in sequence, gradually opening the second to third, third to fourth independent spaces, realizing the gradual expansion of the impact area, which not only ensures the concentration of impact energy, but also can accurately cover different chest wall areas, when the last independent space is completed, at this time, all the force receiving members 7 are at the set position, part of the circular shaft 93 is also embedded in the circular groove 711 of the pneumatic plate 71, located between the upper magnetic strip 501 and the lower magnetic strip 701, at this time, the airflow pressure in the one-way air pipe 62 increases, pushing the thin piece 94 to move downwards, driving the sliding rod 91 to slide along the one-way air pipe 62 and compressing the return spring 92, the circular shaft 93 moves downwards and separates the upper magnetic strip 501 and the lower magnetic strip 701, after the separation force is superimposed with the elastic force of the reset spring 74, it is greater than the magnetic strip adsorption force, forcing all the pneumatic plates 71 to move downwards synchronously, driving the vertical rod 72, the transmission rod 73 and the sealing plate 11 to reset, the arc piece 8 returns to the initial angle under the action of the torsional spring 101, re-closing the bottom arc slot 601, then the return spring 92 pulls the sliding rod 91 and the circular shaft 93 to move back, the equipment returns to the initial state, entering the next round of gradual impact and synchronous reset cycle, finally, through the coordinated linkage of each component, the high-efficiency and human-physiological-law-matching partition sputum drainage is realized.
