Description

Technical Field

[0001] The invention relates to the field of respiratory training equipment, in particular to a lung function rehabilitation training device. Background Art

[0002] For people who suffer from respiratory diseases (such as asthma, chronic obstructive pulmonary disease, etc.) or have undergone lung surgery, trauma, etc., which have impaired lung function, they often experience breathing difficulties in daily activities, which seriously limits their range of activities and ability to take care of themselves. Through lung function rehabilitation exercises, the degree of breathing difficulties will gradually decrease after improving respiratory function. Patients will be able to more easily carry out simple daily activities such as dressing, washing, going up and down stairs, and can even gradually resume certain social activities and outdoor sports, greatly improving the convenience and richness of life.

[0003] Existing rehabilitation exercise methods include deep breathing and lip pursed breathing training, aerobic exercise, balloon blowing exercise, etc.

[0004] Deep breathing and pursed lip breathing training requires patients to purse their lips and exhale slowly, while deep breathing focuses on expanding the lungs as much as possible when inhaling. Although these methods are simple and easy to use, they lack accurate quantification and standardized guidance on breathing intensity and frequency, making it difficult for patients to accurately grasp the training effect and not easy to adhere to scientific and systematic training for a long time. Moreover, in the absence of auxiliary tools, it is difficult for some patients with weak respiratory muscles or severe conditions to achieve ideal rehabilitation effects through independent training.

[0005] Aerobic exercise, such as walking, jogging, swimming, etc., is helpful for improving overall cardiopulmonary function. However, this type of exercise is greatly affected by external environmental factors. For example, outdoor exercise cannot be performed when the weather is bad. At the same time, individual differences among patients are obvious, and it is difficult to accurately control whether the exercise intensity is suitable for their own lung function. There may be situations where the exercise intensity is too high, causing the condition to worsen, or the intensity is too low to achieve the purpose of rehabilitation exercise.

[0006] Blowing a balloon is a common method of exercising the respiratory muscles. It is done by blowing air into the balloon to strengthen the expiratory muscles. However, the balloon itself cannot provide adjustable resistance, the training is not scientific and targeted enough, and there are safety hazards such as balloon rupture during use. In addition, balloon blowing training can only be used for exhalation training, which has a single function and cannot fully take into account the rehabilitation needs of all aspects of lung function.

[0034] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0036] Example 1

[0037] like Figure 1 , Figure 2 As shown, in order to facilitate more scientific and comprehensive lung function rehabilitation and to be suitable for patients to perform lung function rehabilitation exercises, this embodiment provides a device for lung function rehabilitation training, which can be convenient for users to carry with them and can facilitate users to perform continuous breathing training. At the same time, the resistance of breathing can be adjusted according to needs, thereby helping to improve the physical health of users.

[0038] The device includes an intermediate tube 3, a first end cap 1, a second end cap 2, a plurality of gas pipe groups 5, etc. The first end cap 1 and the second end cap 2 are respectively sleeved on the two ends of the intermediate tube 3, and can rotate relative to the intermediate tube 3, and can move along the length direction of the intermediate tube 3. The plurality of gas pipe groups 5 are all arranged on the inner side of the intermediate tube 3 and arranged along the length direction of the intermediate tube 3. At the same time, the plurality of gas pipe groups 5 are evenly distributed along the circumferential direction of the intermediate tube 3. In addition, the diameters of the middle parts of the plurality of gas pipe groups 5 are different. Air holes are arranged at the edges of the first end cap 1 and the second end cap 2, and a mouthpiece 11 is detachably arranged at the air hole of the first end cap 1, and the two ends of a certain gas pipe group 5 are connected to the air holes of the first end cap 1 and the second end cap 2. Therefore, the user places the mouthpiece 11 on the mouth, and exhales and inhales through the gas pipe group 5, and uses the different thicknesses of the gas pipe group 5 to create different resistances to the circulation of gas, thereby realizing the breathing training of the user and improving the lung function.

[0039] In addition, since the first end cover 1 and the second end cover 2 can be adjusted relative to the middle tube 3, the restrictions of the contact end covers and the middle tube 3 can be avoided when necessary to control the middle tube 3 to drive the multiple gas pipe groups 5 to rotate, adjust the connection between the gas pipe groups 5 and the air holes of the end covers, and utilize the different diameters of the multiple gas pipe groups 5 to produce different resistances to gas circulation, thereby achieving scientific lung function rehabilitation training for users.

[0040] like Figure 7As shown, in order to make the gas flow encounter resistance, the gas pipe group 5 includes a resistance tube 51 and two end tubes 52. The two end tubes 52 are respectively arranged at the two ends of the resistance tube 51. The diameter of the resistance tube 51 is less than or equal to the diameter of the end tube 52. The end tube 52 of a certain gas pipe group 5 is arranged to communicate with the air holes of the first end cover 1 and the second end cover 2. Therefore, a gas flow channel is formed under the cooperation of the resistance tube 51 and the end tube 52.

[0041] In order to make the multiple air supply pipe groups 5 produce different resistances to gas circulation, the diameters of the multiple resistance tubes 51 are changed in steps, that is, the resistance of the multiple air supply pipe groups 5 to gas is changed, providing support for scientific lung function rehabilitation training.

[0042] like Figure 3 As shown, in order to ensure that the gas delivery pipe group 5 is stably and sealedly connected to the air hole of the end plate, and the nozzle 11 can be removed as needed, a second internally threaded tube 17 is provided at the air hole, and a threaded structure 12 is provided at the end of the nozzle 11, and the thread is inserted into the second internally threaded tube 17. An annular baffle 18 is fixedly provided on the inner side of the second internally threaded tube 17, and the end of the end tube 52 can be inserted into the second internally threaded tube 17 and contact the annular baffle 18 through a sealing ring, so as to achieve a stable and sealed connection between the end tube 52 and the second internally threaded tube 17.

[0043] like Figure 6 As shown, in order to stably install the gas pipe group 5 in the intermediate pipe 3, fastening mechanisms 7 are provided at both ends of the multiple gas pipe groups 5, and the fastening mechanisms 7 are connected to the intermediate pipe 3. Therefore, under the action of the fastening mechanisms 7, the gas pipe group 5 can be stably installed in the intermediate pipe 3, and convenience is provided for disassembly and replacement according to needs.

[0044] like Fig. 9 , Fig.10 As shown, specifically, the fastening mechanism 7 includes a plurality of first arc plates 71 and a second arc plate 75, the central angle of the first arc plate 71 and the second arc plate 75 is less than 180°, the number of the plurality of first arc plates 71 and the second arc plate 75 is equal to the number of the gas transmission pipe group 5, and the plurality of first arc plates 71 are fixedly mounted on the side wall of the intermediate pipe 3, and the second arc plate 75 is detachably arranged on the side of the first arc plate 71. A diagonal support plate 74 is hingedly arranged on the side of each second arc plate 75, and the ends of the plurality of diagonal support plates 74 are hingedly arranged on the limiting tube 73, and the acting force between the diagonal support plate 74 and the second arc plate 75 and the limiting tube 73 is relatively large, and when the diagonal support plate 74 simply bears the gravity of the second arc plate 75 and the diagonal support plate press 74, its inclination angle will not change.

[0045] like Fig. 9As shown, in addition, the limiting tube 73 can be adjustably installed on the auxiliary mechanism 8, and the auxiliary mechanism 8 is fixedly connected to the intermediate tube 3. At the same time, the first arc plate 71 and the second arc plate 75 are spliced ​​and sleeved on the end tube 52. Therefore, when controlling the movement of the limiting tube 73 relative to the auxiliary mechanism 8, the inclination angle of the diagonal support plate 74 can be adjusted to force the second arc plate 75 to be close to the first arc plate 71, thereby squeezing the end tube 52, so that the gas supply pipe group 5 is stably installed relative to the intermediate tube 3, and it is convenient to disassemble the gas supply pipe group 5.

[0046] like Fig.11 As shown, in order to be able to control the movement of the limiting tube 73 to adjust the inclination angle of the diagonal support plate 74, the auxiliary mechanism 8 includes a fixed plate 81 and a threaded rod 84. The fixed plate 81 is fixedly installed on the intermediate tube 3, and a limiting hole 82 and a threaded connecting hole 83 are provided at the end thereof. The diameter of the threaded connecting hole 83 is larger than the diameter of the limiting hole 82, and the threaded rod 84 is threadedly inserted at the threaded connecting hole 83. The end of the limiting tube 73 is inserted into the limiting hole 82. Since the length of the limiting tube 73 is larger than the length of the limiting hole 82, its end extends into the threaded connecting hole 83 and contacts with the threaded rod 84. Then, when the threaded rod 84 is rotated by an external force, the limiting tube 73 can be controlled to move along the length direction of the limiting hole 82, thereby driving the end of the diagonal support plate 74 to move, thereby realizing the adjustment of the inclination angle of the diagonal support plate 74, and providing support for the stable installation of the first arc plate 71 and the second arc plate 75 splicing and limiting the gas supply pipe group 5.

[0047] like Fig.11 As shown, in order to facilitate the control of the rotation of the threaded rod 84, a polygonal groove 86 is provided on the threaded rod 84. The size of the polygonal groove 86 is smaller than the size of the limiting tube 73. Therefore, a polygonal wrench can be passed through the limiting tube 73, and the end portion can be inserted into the polygonal groove 86. The rotation of the threaded rod 84 is controlled by rotating the polygonal wrench, and the movement of the threaded rod 84 is controlled, thereby driving the limiting tube 73 to move.

[0048] like Figure 7 , Fig. 9 , Fig.10 As shown, in order to connect the end pipe 52 with the first arc plate 71 in the initial stage of connection between the end pipe 52 and the first arc plate 71, a limiting ring plate 53 is fixedly provided on the outer side of the end pipe 52, and a first arc groove 72 is provided on the side wall of the first arc plate 71. The end of the first arc groove 72 is set to be an opening, and a rubber layer is provided on the side wall of the first arc groove 72. Therefore, after the limiting ring plate 53 extends into the first arc groove 72, under the action of the rubber layer, the resistance of the limiting ring plate 53 to move relative to the first arc plate 71 is increased, thereby making the gas supply pipe group 5 relatively stably placed relative to the first arc plate 71.

[0049] In addition, a second arc groove 76 may be provided on the side wall of the second arc plate 75, and the end of the second arc groove 76 may be set as an opening. Therefore, after the second arc plate 75 is sleeved on the end pipe 52, the limiting ring plate 53 is located in the first arc groove 72 and the second arc groove 76, thereby making the gas supply pipe group 5 and the first arc plate 71 and the second arc plate 75 relatively stably placed.

[0050] like Figure 2 , Figure 6 As shown, in order to make the first end cover 1 and the second end cover 2 stable and adjustably arranged at the ends of the intermediate tube 3, an adjusting mechanism 6 is arranged through the middle of the inner side of the intermediate tube 3. The adjusting mechanism 6 is movably arranged relative to the intermediate tube 3, and the ends are adjustably connected to the first end cover 1 and the second end cover 2. Therefore, the first end cover 1 and the second end cover 2 can be controlled to move relative to the intermediate tube 3 by rotating the adjusting mechanism 6, so as to release the restriction between the end cover and the gas pipe group 5, and provide convenience for adjusting the connection between the gas pipe group 5 and the end cover.

[0051] like Figure 8 , Fig.11 As shown, specifically, the adjustment mechanism 6 includes a transmission shaft 61 and two threaded columns 64. A support plate 62 is provided in the middle of the transmission shaft 61 through a bearing connection sleeve, and the support plate 62 is connected to the intermediate tube 3. In order to prevent the existence of the auxiliary mechanism 8 and the fastening mechanism 7 from affecting the installation of the transmission shaft 61, a through hole 85 is provided at the end of the polygonal groove 86, and the transmission shaft 61 is provided through the through hole 85, and the diameter of the transmission shaft 61 is smaller than the diameter of the through hole 85. Therefore, on the premise of satisfying the installation of the transmission shaft 61, it is convenient for the transmission shaft 61 to rotate. The two threaded columns 64 are respectively arranged at both ends of the transmission shaft 61, and the ends close to each other are fixedly provided with an end shaft 65, and the end shaft 65 is connected to the transmission shaft 61 through a coupling 63. Therefore, when one threaded column 64 rotates, the other threaded column 64 rotates synchronously. In addition, a first internally threaded tube 16 is disposed in the middle of the first end cap 1 and the second end cap 2, and a threaded column 64 is threadedly inserted into the first internally threaded tube 16. Therefore, when the two threaded columns 64 rotate, the first end cap 1 and the second end cap 2 can be forced to move closer to or farther from each other, providing support for removing the restriction between the gas delivery pipe group 5 and the end caps. In order to control the rotation of the threaded columns 64, a rotating disk 66 is disposed on the side of one of the threaded columns 64, and the rotating disk 66 is located on the side of the end cap away from the intermediate pipe 3.

[0052] Example 2

[0053] like Figure 3 , Figure 4As shown, on the basis of Example 1, in order to facilitate the user to hold the device and provide support for the relative movement of the first end cover 1 and the second end cover 2, a bottom plate 13 is fixedly arranged below the first end cover 1 and the second end cover 2, a plug plate 14 is fixedly arranged at the bottom of the bottom plate 13, and a buckle groove 15 is arranged on the side wall of the plug plate 14. A connecting plate 4 is arranged between the two bottom plates 13, a slot 43 is arranged at the end of the connecting plate 4, and a buckle column 44 is arranged on the side wall of the slot 43. The plug plate 14 is inserted into the slot 43, and the buckle column 44 is located in the buckle groove 15, so that the bottom plate 13 and the connecting plate 4 are connected movably and stably, and a handle is formed, which is convenient for the user to hold, and at the same time, it is convenient for the first end cover 1 and the second end cover 2 to move relative to each other.

[0054] like Figure 4 , Figure 5 As shown, the connecting plate 4 can also be connected to the intermediate pipe 3, for example, a socket 41 is provided on the connecting plate 4, and a threaded hole 42 is provided on the side wall of the socket 41, so that a vertical plate 35 is installed at the socket 41 through bolt connection. An arc clamping plate 33 is fixedly provided on the top of the vertical plate 35, and the arc clamping plate 33 is sleeved on the intermediate pipe 3 and is located between two annular plates 31 fixedly installed on the intermediate pipe 3, so as to limit the position of the arc clamping plate 33 relative to the intermediate pipe 3. The side walls of the arc clamping plate 33 and the intermediate pipe 3 are provided with mutually meshing protrusions 34 and grooves 32, which provide convenience for quantitatively rotating the intermediate pipe 3 and the gas delivery pipe group 5 when the intermediate pipe 3 rotates relative to the arc clamping plate 33. In addition, an indicator mark can be provided at the end of the intermediate pipe 3 to provide support for quantitatively adjusting the connection between the gas delivery pipe group 5 and the end cover.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
