Description

Technical Field

[0001] This invention relates to the field of rehabilitation equipment technology, and in particular to a pulmonary function rehabilitation training device after thoracic surgery. Background Technology

[0002] Following cardiothoracic surgery, patients require physical therapy in addition to medication to aid lung function recovery and reduce postoperative complications. A common approach is to increase expiratory resistance to improve respiratory muscle function. Current technology typically uses a pulmonary function training device, which includes a trachea and a transparent box with graduations on the outside. Inside the box are movable balls or plugs. By blowing air into the trachea, the balls or plugs float, thus generating expiratory resistance. The intensity of the expiratory resistance can be adjusted by changing the weight or number of balls or plugs.

[0003] Because the lung tissue on the surgical side collapses, there is often a lot of secretions in the lung tissue after surgery, which form sputum. If this sputum is not coughed up through active coughing and respiratory exercises after surgery, it may block the trachea and bronchi, leading to atelectasis of part or even one lung. In addition, the accumulation of sputum in the lungs can easily lead to serious lung infections and even affect the healing of bronchial stumps, thus affecting the patient's recovery. When patients blow air during lung function training, sputum and saliva can easily enter the training device with the air, which can block the training device and affect training and use. On the other hand, it is not easy to clean the sputum inside the training device. Therefore, this application provides a lung function rehabilitation training device after thoracic surgery to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a pulmonary function rehabilitation training device after thoracic surgery, so as to solve the problem that when the patient blows air into the training device, sputum and saliva can easily enter the training device, which can clog the training device and affect the training. On the other hand, it is not easy to clean the sputum inside the training device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A pulmonary function rehabilitation training device after thoracic surgery includes an articulated air tube and a transparent tube, the air tube and the transparent tube being connected, and a float that can move through airflow is provided inside the transparent tube; it also includes a liquid removal component for isolating and collecting sputum in the air tube, the liquid removal component being connected to the air tube.

[0007] Optionally, the liquid removal assembly includes an inner tube located inside the air blowing pipe and a support component sleeved on the inner tube. A rubber stopper is fixedly connected to one end of the inner tube. The connection between the rubber stopper and the inner tube is inclined, and an arc-shaped cavity is formed at the connection between the inner tube and the rubber stopper. A first arc-shaped portion is fixedly connected to the rubber stopper along the direction of the inner tube. A second arc-shaped portion is formed at the connection between the first arc-shaped portion and the rubber stopper. A beveled portion is fixedly connected to the end of the first arc-shaped portion away from the second arc-shaped portion. The connection between the first arc-shaped portion and the second arc-shaped portion is an arc-shaped structure. The inner tube... A venting groove is formed on the upper wall, and a liquid inlet is formed on the lower wall of the inner tube. A guide plate is also fixedly connected to the bottom wall of the inner tube. A V-shaped guide groove is formed on the guide plate. One end of the guide plate is close to the rubber stopper, and the other end of the guide plate faces the liquid inlet and gradually slopes downward. A U-shaped gasket is inserted into the venting groove. Both sides of the gasket are bent outward to form a gasket surface that fits the curvature of the inner wall of the air blowing tube. Rubber rings are fixedly connected to both ends of the gasket. A central hole is formed in the center of the rubber ring, and a connecting hole is formed at the connection between the rubber ring and the gasket.

[0008] Optionally, the supporting component includes an elastic tube that mates with the central hole. A through slot is formed on the upper wall of the elastic tube. A plurality of elastic strips are fixedly connected to one end of the elastic tube, and a plurality of elastic sheets are fixedly connected to the other end. Arc-shaped protrusions are fixedly connected to the elastic sheets and elastic strips, and these arc-shaped protrusions abut against grooves formed on the inner circumferential sidewall of the rubber ring. An arc-shaped ring is fixedly connected to the end of the elastic strip away from the elastic tube, abutting against and fitting with the arc-shaped cavity. A first arc-shaped strip is fixedly connected to the end of the arc-shaped ring away from the elastic strip, abutting against and fitting with the first arc-shaped portion. A second arc-shaped strip is formed at the connection point between the arc-shaped ring and the first arc-shaped strip. The second arc-shaped strip abuts against and fits against the second arc-shaped portion. The outer end of the first arc-shaped strip is bent outwards to form a buckle plate, which is inserted into a buckle groove formed on the surface of the inclined portion.

[0009] Optionally, a plurality of corrugated strips are fixedly connected to the outer peripheral sidewall of the rubber ring, and the rubber ring and the plurality of corrugated strips are integrally formed.

[0010] Optionally, the air inlet end of the air blowing pipe gradually narrows outward, and the outermost end of the air inlet end has an arc-shaped protrusion. The end of the air blowing pipe away from the air inlet end is an open end, and the inner peripheral sidewall of the open end gradually slopes outward to form a beveled opening. The beveled opening abuts against the beveled part and the bottom wall of the arc-shaped structure.

[0011] Optionally, a removable second stopper is installed inside the opening end. The second stopper includes a second protrusion that engages with the inner tube and a first protrusion that engages with the inclined opening. A fixing plate is fixedly connected to the air blowing tube. The transparent tube is hinged inside the fixing plate. A shrink tube is fixedly connected to the air blowing tube. The transparent tube and the air blowing tube are connected through the shrink tube. A removable first stopper is installed at one end of the transparent tube. The first stopper and the air inlet end on the air blowing tube are limited and fixed.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] In the above scheme, by setting an inner tube inside the blowing tube, and setting an inclined guide plate on the bottom wall of the inner tube, with the lowest end of the guide plate facing downwards from the inlet, and the highest end of the guide plate located at the connection between the foot plug and the inner tube, when sputum enters the inner tube, it will not affect the patient's normal blowing training. Furthermore, the guide plate extends inclinedly to the bottom of the inlet, allowing the sputum on the guide plate to flow smoothly through the inclined surface into the space between the inner tube and the blowing tube, thereby preventing backflow. By setting the guide plate as a V-shaped guide groove, the V-shaped structure can further concentrate the sputum, facilitating the sputum to slide down the inclined guide plate.

[0014] By setting up an inner tube, a rubber stopper, and a gasket, in the default state, the rubber stopper, the first arc-shaped part, the second arc-shaped part, and the inclined part all extend outward, with the extended size being larger than the inner diameter of the air tube. When the rubber stopper of the integrated structure is inserted into the air tube, it can fit against the inner wall, thereby ensuring a sealing effect. In addition, the second arc-shaped part can also block and reduce the leakage of sputum from the arc-shaped cavity, and the gasket can prevent sputum between the air tube and the inner tube from entering the transparent tube.

[0015] By setting up a support component consisting of an elastic tube, several elastic strips, an arc ring, and a second arc strip and a first arc strip, the rubber ring is supported and prevented from deforming on the one hand, and the fit between the rubber ring and the inner wall of the air tube is further improved on the other hand.

[0016] Several elastic strips at the end furthest from the elastic tube are extended outwards by default. After the arc-shaped ring is inserted into the arc-shaped cavity, the second and first arc-shaped strips on the elastic strips fit against the second and first arc-shaped parts respectively. At the same time, the buckle plate is inserted into the buckle groove on the beveled part, thus supporting the rubber plug and improving the fit between the rubber plug and the inner wall of the air tube. Furthermore, the supporting component can maintain a fixed distance between the rubber plug and the rubber ring. The rubber ring at one end of the supporting component is fixed in the air groove, so that the rubber plug at the other end of the supporting component is kept at the air inlet end of the air tube, thereby preventing the rubber plug from moving. Phlegm entering between the air tube and the inner tube will be confined between the rubber plug and the rubber ring, making it easier to scrape into the arc-shaped cavity. In addition, because the supporting component improves the tightness between the rubber plug, rubber ring and the inner wall of the air tube, the scraping effect is further improved when the rubber plug and rubber ring are pulled out of the air tube.

[0017] By setting an outward-sloping bevel at the opening of the air inlet tube, the rubber plug can be slowed down during the removal process, preventing the sudden detachment of the plug and the resulting ejection of phlegm from the arc-shaped cavity and the airway. Attached Figure Description

[0040] like Figures 1 to 13 As shown, an embodiment of the present invention provides a pulmonary function rehabilitation trainer after thoracic surgery, including an articulated air tube 1 and a transparent tube 2, the air tube 1 and the transparent tube 2 being connected, and a float that can be moved by airflow being disposed inside the transparent tube 2; it also includes a liquid removal component for isolating and collecting sputum in the air tube 1, the liquid removal component being connected to the air tube 1.

[0041] like Figure 2 , Figure 3 and Figure 7The liquid removal assembly includes an inner tube 7 located in the air blowing pipe 1, and a support component sleeved on the inner tube 7. A rubber stopper 8 is fixedly connected to one end of the inner tube 7. The connection between the rubber stopper 8 and the inner tube 7 is an inclined structure, and an arc-shaped cavity 9 is formed at the connection between the inner tube 7 and the rubber stopper 8. A first arc-shaped portion 14 is fixedly connected to the rubber stopper 8 along the direction of the inner tube 7. A second arc-shaped portion 15 is formed at the connection between the first arc-shaped portion 14 and the rubber stopper 8. A beveled portion 16 is fixedly connected to the end of the first arc-shaped portion 14 away from the second arc-shaped portion 15. The connection between the first arc-shaped portion 14 and the second arc-shaped portion 15 is an arc-shaped structure 17. An air vent 13 is provided on the upper wall of the inner tube 7, and a liquid inlet 12 is provided on the lower wall of the inner tube 7. The ventilation slot 13 and the inlet 12 are arranged opposite to each other, and a guide plate 10 is fixedly connected to the bottom wall of the inner tube 7. One end of the guide plate 10 is close to the rubber stopper 8, and the other end of the guide plate 10 faces the inlet 12 and gradually tilts downward. By setting the inclined guide plate 10 on the bottom wall of the inner tube 7, with the lowest end of the guide plate 10 facing below the inlet 12 and the highest point of the guide plate 10 located at the connection between the foot plug 8 and the inner tube 7, if sputum enters the inner tube 7 during blowing, the sputum will slide down the inclined guide plate 10 on the bottom wall of the inner tube 7 to the inlet 12, and finally enter between the blowing tube 1 and the inner tube 7. Therefore, after sputum enters the inner tube 7, it will not affect the patient's normal blowing training.

[0042] like Figure 10 and Figure 11The ventilation groove 13 is fitted with a U-shaped plug 35. Both sides of the plug 35 are bent outwards to form a pad surface 36 that conforms to the curvature of the inner wall of the air tube 1. Rubber rings 32 are fixedly connected to both ends of the plug 35. A central hole 34 is formed in the center of each rubber ring 32, and a connecting hole 37 is formed at the connection between the rubber ring 32 and the plug 35. An inner tube 7 and a plug 8 are provided, and the inner tube 7 and the plug 8 are fixedly connected. The plug 8 has a second arc-shaped portion 15, a first arc-shaped portion 14, and a beveled portion 16 sequentially fixedly connected along the direction of the inner tube 7. An arc-shaped cavity 9 is formed at the connection between the inner tube 7 and the plug 8. All components are made of elastic rubber and are integrally formed. In the default state, the plug 8, the first arc-shaped portion 14, the second arc-shaped portion 15, and the beveled portion 16 are all extended outwards, with the extended dimension greater than the inner diameter of the air tube 1. When the integrally formed plug 8 is inserted into the air tube 1, it can... The inner tube 7 is fitted to the inner wall to ensure a tight seal. During cleaning, the inner tube 7 is pulled outward. The rubber stopper 8 can be pushed backward first, and after the inner tube 7 extends beyond the air tube 1, the inner tube 7 is pinched and pulled outward. The beveled part 16 on the rubber stopper 8 is similar to a shovel. During the movement of the rubber stopper 8, the sputum on the inner wall of the air tube 1 can be scooped up. The sputum flows along the curved first arc part 14 and the second arc part 15 into the circular arc cavity 9 for storage. Since the second arc part 15 is higher than the first arc part 14, the sputum is stored after entering the arc cavity 9, and it can also prevent the sputum in the arc cavity 9 from overflowing during the movement of the rubber stopper 8. By setting a U-shaped pad 35, the pad 35 is inserted into the air groove 13 and fits the shape of the inner tube 7. The arc-shaped pads 36 at both ends of the pad 35 fit the inner wall of the air tube 1, thus preventing the sputum between the air tube 1 and the inner tube 7 from entering the transparent tube 2.

[0043] like Figure 3 The guide plate 10 is provided with a V-shaped guide groove 11. By setting the guide plate 10 to a V-shaped guide groove 11, the V-shaped structure can further concentrate the sputum and facilitate the sputum to slide down the inclined guide plate 10.

[0044] like Figure 4 and Figure 12The supporting component includes an elastic tube 23 that mates with the central hole 34. A through slot 24 is provided on the upper wall of the elastic tube 23. A plurality of elastic strips 25 are fixedly connected to one end of the elastic tube 23, and a plurality of elastic plates 26 are fixedly connected to the other end. Arc-shaped protrusions 27 are fixedly connected to both the elastic plates 26 and the elastic strips 25. The arc-shaped protrusions 27 abut against grooves 33 formed on the inner circumferential sidewall of the rubber ring 32. The support component is composed of the elastic tube 23, a plurality of elastic strips 25, an arc-shaped ring 28, a second arc-shaped strip 29, and a first arc-shaped strip 30. The support component is formed, and several elastic strips 25 are arranged around the elastic tube 23. The through slot 24 opened on the elastic tube 23 is aligned with the air groove 13. During installation, the elastic tube 23 is located in the central hole 34. Since several elastic strips 25 and several elastic plates 26 are respectively arranged at both ends of the elastic tube 23, and arc-shaped protrusions 27 are arranged on both the elastic strips 25 and the elastic plates 26, the arc-shaped protrusions 27 are stuck in the grooves 33 that match the rubber ring 32. On the one hand, it supports the rubber ring 32 and prevents deformation, and on the other hand, it further improves the fit between the rubber ring 32 and the inner wall of the air tube 1.

[0045] like Figure 4 , Figure 10 and Figure 11 The elastic strip 25, at the end away from the elastic tube 23, is fixedly connected to an arc-shaped ring 28 that abuts against and fits against the arc-shaped cavity 9. The arc-shaped ring 28, at the end away from the elastic strip 25, is fixedly connected to a first arc-shaped strip 30 that abuts against and fits against the first arc-shaped portion 14. The connection between the arc-shaped ring 28 and the first arc-shaped strip 30 is a second arc-shaped strip 29, which abuts against and fits against the second arc-shaped portion 15. The outer end of the first arc-shaped strip 30 is bent outwards to form a buckle plate 31. The buckle plate 31 is inserted into a buckle groove 18 formed on the surface of the inclined portion 16. In its default state, several elastic strips 25 at the end away from the elastic tube 23 are extended outwards. After the arc-shaped ring 28 is inserted into the arc-shaped cavity 9, the second arc-shaped strip 29 and the first arc-shaped strip 30 on the elastic strip 25 respectively fit against the second arc-shaped portion 15 and the first arc-shaped portion 14. Simultaneously, the buckle plate 31 is inserted into the buckle groove 18 on the inclined portion 16. The support member 8 provides support for the rubber stopper 8 and improves the fit between the rubber stopper 8 and the inner wall of the air tube 1. Additionally, the surrounding elastic strip 25 and elastic sheet 26 evenly support the rubber stopper 8 and the rubber ring 32. Since the rubber stopper 8 and the rubber ring 32 are located at opposite ends of the support member, the support member also maintains a fixed distance between the rubber stopper 8 and the rubber ring 32. The rubber ring 32 at one end of the support member is fixed within the air passage 13, keeping the rubber stopper 8 at the air inlet end of the air tube 1, thus preventing the rubber stopper from moving. Furthermore, phlegm entering between the air tube 1 and the inner tube 7 is confined between the rubber stopper 8 and the rubber ring 32, facilitating scraping into the arc-shaped cavity 9. Moreover, because the support member improves the tightness between the rubber stopper 8, the rubber ring 32, and the inner wall of the air tube 1, the rubber stopper 8 and the rubber ring 32 can be scraped more effectively when the air tube 1 is pulled out.

[0046] like Figure 10 The outer peripheral sidewall of the rubber ring 32 is fixedly connected with several corrugated strips 38. The rubber ring 32 and the corrugated strips 38 are integrally formed. The corrugated strips 38 cooperate with each other to increase the friction between the outer wall of the rubber ring 32 and the inner wall of the air blowing pipe 1, thereby improving the sealing effect of the rubber ring 32.

[0047] like Figure 1 and Figure 6 The air inlet of the blowing tube 1 gradually narrows outward to facilitate taking it into the mouth, and the outermost end of the air inlet has an arc-shaped protrusion 22. When blowing air, the arc-shaped protrusion 22 plays a limiting role in the mouth, improving stability.

[0048] like Figure 7 and Figure 8 The end of the air inlet tube 1 furthest from the air inlet is an open end, and the inner circumferential sidewall of the open end gradually slopes outward to form a beveled opening 19. The beveled opening 19 abuts against the beveled part 16 and the bottom wall of the arc structure 17. By setting the outwardly inclined beveled opening 19 at the open end of the air inlet tube 1, the elastic material first arc part 14, second arc part 15 and other structures support and expand the rubber plug 8. When the rubber plug 8 is pulled out, the outermost beveled part 16 on the rubber plug 8 expands outward, and its bottom contacts the beveled opening 19. Since the first arc part 14 is arc-shaped, after the beveled part 16 is pulled out, the first arc part 14 at the rear end of the beveled part 16 contacts the beveled opening 19, so that the first arc part 14 can gradually slide outward while closely adhering to the beveled opening 19, thereby slowing down the rubber plug 8 during the pulling process and preventing the problem of phlegm being thrown out of the arc cavity 9 and the air inlet tube 1 due to sudden detachment.

[0049] like Figure 1 and Figure 8 The blowing tube 1 is fixedly connected to a fixing plate 3, and the transparent tube 2 is hinged inside the fixing plate 3. The blowing tube 1 is fixedly connected to a shrink tube 4, and the transparent tube 2 and the blowing tube 1 are connected through the shrink tube 4. One end of the transparent tube 2 is equipped with a detachable first stopper 5, which limits and fixes the air inlet end on the blowing tube 1. The first stopper 5 is made of rubber and has a notch on its inner surface. When not in use, the blowing tube 1 can be rotated and its air inlet end can be locked in the notch in the first stopper 5. A detachable second stopper 6 is installed in the open end. The second stopper 6 includes a second protrusion 21 that is inserted into the inner tube 7 and a first protrusion 20 that is inserted into the inclined opening 19. The first protrusion 20 seals the blowing tube 1, and the second protrusion 21 seals the inner tube 7 to prevent air leakage. In addition, the second stopper 6 and the first stopper 5 can protect the two ends of the blowing tube 1 and the transparent tube 2 if they fall.

[0050] The working principle of this invention is as follows: by setting an inclined guide plate 10 on the bottom wall of the inner tube 7, with the lowest end of the guide plate 10 facing downwards from the inlet 12 and the highest end of the guide plate 10 located at the connection between the foot plug 8 and the inner tube 7, when blowing air, if sputum enters the inner tube 7, the sputum will slide down the inclined guide plate 10 on the bottom wall of the inner tube 7 to the inlet 12, and finally enter between the blowing tube 1 and the inner tube 7. Therefore, after sputum enters the inner tube 7, it will not affect the patient's normal blowing training.

[0051] By setting an inner tube 7 and a rubber stopper 8, and fixing the inner tube 7 and the rubber stopper 8 together, the rubber stopper 8 is sequentially fixedly connected with a second arc-shaped part 15, a first arc-shaped part 14, and a beveled part 16 along the direction of the inner tube 7, and an arc-shaped cavity 9 is formed at the connection between the inner tube 7 and the rubber stopper 8. All of these are made of elastic rubber and are integrally molded. In the default state, the rubber stopper 8, the first arc-shaped part 14, the second arc-shaped part 15, and the beveled part 16 are all extended outward, and the extended size is larger than the inner diameter of the air blowing tube 1. When the integrally structured rubber stopper 8 is inserted into the air blowing tube 1, it can fit against the inner wall, thereby ensuring a sealing effect. During cleaning, the inner tube 7 is pulled outward, and the beveled part 16 on the rubber stopper 8 is removed. 6. First, the sputum on the inner wall of the air tube 1 is stored in the arc-shaped cavity 9 along the first arc-shaped part 14 and the second arc-shaped part 15. The second arc-shaped part 15 can also block and reduce the overflow of sputum in the arc-shaped cavity 9. By setting a U-shaped plug 35, the plug 35 is inserted into the ventilation groove 13 and fits the shape of the inner tube 7. The arc-shaped pads 36 at both ends of the plug 35 are in contact with the inner wall of the air tube 1. Therefore, it can prevent sputum between the air tube 1 and the inner tube 7 from entering the transparent tube 2. By setting the guide plate 10 as a V-shaped guide groove 11, the V-shaped structure can further concentrate the sputum and facilitate the sputum to slide down the inclined guide plate 10.

[0052] By setting up a support component consisting of an elastic tube 23, several elastic strips 25, an arc ring 28, a second arc strip 29, and a first arc strip 30, with several elastic strips 25 arranged around the elastic tube 23, and the through slot 24 opened on the elastic tube 23 aligned with the air vent 13, the elastic tube 23 is located in the central hole 34 during installation. Since several elastic strips 25 and several elastic plates 26 are respectively provided at both ends of the elastic tube 23, and arc protrusions 27 are provided on both the elastic strips 25 and the elastic plates 26, the arc protrusions 27 are stuck in the grooves 33 that match the rubber ring 32, on the one hand supporting the rubber ring 32 and preventing deformation, and on the other hand further improving the fit between the rubber ring 32 and the inner wall of the air blowing pipe 1.

[0053] In the above structure, several elastic strips 25 at the end away from the elastic tube 23 are extended outwards by default. After the arc-shaped ring 28 is inserted into the arc-shaped cavity 9, the second arc-shaped strip 29 and the first arc-shaped strip 30 on the elastic strip 25 respectively fit against the second arc-shaped part 15 and the first arc-shaped part 14. At the same time, the buckle plate 31 is inserted into the buckle groove 18 on the inclined part 16, thus supporting the rubber plug 8 and improving the fit between the rubber plug 8 and the inner wall of the air tube 1. In addition, the surrounding elastic strips 25 and elastic sheets 26 evenly support the rubber plug 8 and the rubber ring 32 respectively. At the same time, since the rubber plug 8 and the rubber ring 32 respectively The support component is positioned at both ends of the support component. The support component can also maintain a fixed distance between the rubber plug 8 and the rubber ring 32. The rubber ring 32 at one end of the support component is fixed in the air groove 13, so that the rubber plug 8 at the other end of the support component is kept at the air inlet end of the air tube 1, thereby preventing the rubber plug from moving. Furthermore, the phlegm that enters between the air tube 1 and the inner tube 7 will be confined between the rubber plug 8 and the rubber ring 32, making it easier to scrape into the arc-shaped cavity 9. In addition, since the support component improves the tightness between the rubber plug 8, the rubber ring 32 and the inner wall of the air tube 1, the rubber plug 8 and the rubber ring 32 can achieve a better scraping effect when the air tube 1 is pulled out.

[0054] By providing an outwardly inclined bevel 19 at the opening end of the air inlet pipe 1, the elastic material, including the first arc-shaped portion 14 and the second arc-shaped portion 15, supports and expands the rubber plug 8. When the rubber plug 8 is pulled out, the outermost bevel 16 on the rubber plug 8 expands outward, and its bottom contacts the bevel 19. Since the first arc-shaped portion 14 is arc-shaped, after the bevel 16 is pulled out, the first arc-shaped portion 14 at the rear end of the bevel 16 contacts the bevel 19, allowing the first arc-shaped portion 14 to gradually slide outward while adhering to the bevel 19. This slows down the rubber plug 8 during the pulling process and prevents it from suddenly detaching and causing phlegm to be thrown out of the arc-shaped cavity 9 and the air inlet pipe 1.
