Description

Technical Field

[0001] The invention relates to the technical field of breathing training equipment, and in particular to a lip-pursed breathing training device. Background Art

[0002] Pursed lip breathing is suitable for patients with severe COPO, who often have overinflation of the lungs during bronchospasm, panic or exercise. It is also used as an auxiliary measure for patients who are undergoing exercise rehabilitation or respiratory muscle training, such as in the later stages of treatment of lung diseases such as chronic obstructive pulmonary disease and bronchial asthma. The purpose of pursed lip breathing training is to improve lung function, help improve pulmonary circulation, and reduce the intrabronchial pressure to prevent bronchial collapse. More importantly, through pursed lip breathing training, the diaphragm muscle strength can be improved, and the chest pressure can be slowly reduced, thereby improving vital capacity.

[0003] When practicing pursed lip breathing, inhale through the nose, exhale with the mouth pursed to apply some resistance, exhale slowly, and the ratio of inhalation to exhalation is 1:2. Exercise gradually to make the ratio of inhalation to exhalation 1:4. Through this breathing method, patients can get a certain degree of contraction and relaxation training of respiratory muscles, which can enhance the improvement of the respiratory motor function of the diaphragm and relieve their clinical symptoms.

[0004] At present, when patients perform lip pursing training in the rehabilitation stage, some patients have weak self-control and are often unable to inhale through the nose and exhale through the mouth. After such practice, the rehabilitation effect of lip pursed breathing is not good; and the existing lip pursed breathing cannot feel the training effect well, which makes it easy for patients to lose the motivation to continue training after a period of training. Summary of the invention

[0042] See also Figure 1 to Figure 2The present invention provides a lip-pursed breathing training device, comprising a mask body 10, an air outlet mechanism 20, an air intake assembly 30 and a detection member 40. The mask body 10 is provided with an air intake hole 11 and an air outlet hole 12, the air intake hole 11 is located above the air outlet hole 12, and both sides of the mask body 10 are worn on the patient's face through binding members 50; the air outlet mechanism 20 is installed on the mask body 10, and the inner end of the air outlet mechanism 20 passes through the air outlet hole 12 and extends to the inner side of the mask body 10 and is covered on the lips, and the air outlet mechanism 20 includes an air outlet inner tube 21, an air outlet outer tube 22 and an adjustable impedance member 23, one end of the air outlet outer tube 22 extends through the air outlet hole 12 to the inside of the mask body 10 and is fixedly connected to the air outlet inner tube 21, the inner end of the air outlet inner tube 21 is used to cover the lips, and the adjusting impedance 23 is arranged in the air outlet outer tube 22 to adjust the impedance of exhalation; the air intake component 30 is installed on the mask body 10, and the inner end of the air intake component 30 extends through the air intake hole 11 to the inside of the mask body 10 and is covered on the nose; the detection component 40 is installed on the end of the air outlet mechanism 20 located on the outside of the mask body 10, and is used to detect the gas flow rate of the patient's exhalation. Among them, the connection between the air intake component 30 and the air intake hole 11 is sealed, and the connection between the air outlet outer tube 22 and the air outlet hole 12 is sealed to avoid air leakage at the air intake hole 11 and the air outlet hole 12, and ensure the sealing of the inside of the mask body 10.

[0043] When in use, the mask body 10 is placed on the outside of the nose and lips, and the inner end of the air inlet component 30 is placed on the nose, while the inner end of the air outlet inner tube 21 is placed on the lips, and then the mask body 10 is fixed by the binding member 50; according to the patient's lung breathing condition, the impedance of exhalation is adjusted by the impedance regulating member, so as to formulate a reasonable exhalation resistance for the patient and ensure the effect of lip pursing training; and due to the setting of the air outlet mechanism 20 and the air inlet component 30, the patient can only inhale through the nose and exhale through the mouth, so that the patient can develop the habit of inhaling through the nose and exhaling through the mouth through long-term training, thereby enhancing the rehabilitation effect of lip pursing breathing; in addition, the setting of the detection member 40 can detect the intensity of the patient's exhaled gas, so that the patient can see the effect of the lip pursing training and enhance the patient's self-confidence in training.

[0044] Please also read Figures 3 to 6Specifically, the impedance adjustment member 23 includes a baffle 231, an impedance outer tube 232, an impedance inner tube 233 and a first spring 234. The baffle 231 is slidably arranged inside the air outlet outer tube 22, and the outer wall of the baffle 231 slides in contact with the inner wall of the air outlet outer tube 22. The impedance outer tube 232 is limitedly slidably arranged inside the air outlet outer tube 22, and one end of the impedance outer tube 232 is a closed end. One end of the impedance inner tube 233 is fixedly connected to the baffle 231, and the other end is inserted into the impedance outer tube 232 for sliding connection. One end of the first spring 234 is fixedly connected to the inner wall of the closed end of the impedance outer tube 232, and the other end is connected to the end of the impedance inner tube 233 located inside the impedance outer tube 232. Among them, a through hole 29 is opened on the air outlet outer tube 22, and the detection member 40 is connected to the through hole 29, so that the gas exhaled by the patient flows into the detection member 40 through the through hole 29 and then is discharged to the outside.

[0045] Before the patient performs lip pursing training, the patient first adjusts the exhalation impedance through the impedance-adjusting member according to the patient's lung breathing conditions. After the patient completes inhalation through the air intake assembly 30, the patient's lips are in a pursed lip state, and then exhales, and the gas flows through the outlet inner tube 21 to the inside of the outlet outer tube 22, so that the exhaled gas pushes the baffle 231 inside the outlet outer tube 22 to move toward the impedance outer tube 232. At this time, the first spring 234 is compressed to generate elastic force, so that the exhaled gas pushes the baffle 231 to move with a certain impedance, and the patient overcomes the impedance force by exhaling, thereby achieving the training effect.

[0046] Preferably, the impedance adjustment member 23 also includes an adjustment knob 235 and a retaining ring 236. The retaining ring 236 is fixedly sleeved on the inner wall of the air outlet outer tube 22, and the retaining ring 236 is located on the side of the baffle 231 away from the impedance inner tube 233. The adjustment knob 235 is rotatably sleeved inside the air outlet outer tube 22. The inner wall of the adjustment knob 235 is threadedly sleeved on the outer wall of the impedance outer tube 232. The middle part of the adjustment knob 235 is provided with a protrusion that rotatably penetrates the side wall of the air outlet outer tube 22 and extends to the outside. A limited sliding groove 221 is provided on the inner wall of the air outlet outer tube 22, and a limited sliding block 239 is fixedly provided on the outer wall of the impedance outer tube 232. The end of the limited sliding block 239 is inserted into the limited sliding groove 221 for sliding connection, so that the impedance outer tube 232 can only move inside the air outlet outer tube 22 and cannot rotate.

[0047] In the initial state, the baffle 231 is in contact with the baffle ring 236. When it is necessary to adjust the size of the patient's initial exhalation impedance force, the protrusion of the adjusting knob 235 is turned to make the adjusting knob 235 drive the impedance outer tube 232 to rotate, thereby making the impedance outer tube 232 move toward the baffle ring 236 inside the intake outer tube 32. At this time, the first spring 234 is squeezed and contracted, so that the impedance inner tube 233 is initially subjected to the elastic force of the first spring 234 toward the baffle ring 236, thereby increasing the impedance force received by the patient during the initial exhalation, so as to adapt to the patient's own lip pursing training intensity and achieve better training effect.

[0048] Furthermore, the impedance member also includes a second spring 237 and a third spring 238, one end of each of the second spring 237 and the third spring 238 is fixedly connected to the inner wall of the closed end of the impedance outer tube 232, the length of the second spring 237 is greater than the length of the third spring 238, and is less than the length of the first spring 234, and the elastic coefficients of the first spring 234, the second spring 237 and the third spring 238 are the same. Due to the different lengths of the first spring 234, the second spring 237 and the third spring 238, the contact distances between the impedance inner tube 233 and the three springs are also different; the end of the impedance inner tube 233 located in the impedance outer tube 232 contacts the first spring 234, the second spring 237 and the third spring 238 in sequence at the same time, so that the impedance strength of the patient's exhalation is continuously increased, thereby adapting to the exhalation strength of different patients, thereby achieving the effect of lip pursing training.

[0049] In this embodiment, the air outlet mechanism 20 also includes a movable induction sheet 24 and a plurality of fixed induction sheets 25. The movable induction sheet 24 is arranged on the outer wall of the impedance inner tube 233. A plurality of fixed induction sheets 25 are arranged on the inner wall of the air outlet outer tube 22 at intervals along the length direction. A plurality of LED lights 26 are arranged on the outer wall of the air outlet outer tube 22. The positions of the plurality of LED lights 26 correspond one-to-one to the positions of the fixed induction sheets 25. The LED lights 26, the fixed induction sheets 25 and the movable induction sheets 24 are electrically connected. When the movable induction sheet 24 contacts the fixed induction sheet 25 at the corresponding position, the LED light 26 at the corresponding position will emit light, so that the patient can see whether the required exhalation intensity and exhalation time are achieved, so that the patient can see the effect of the lip pursing training.

[0050] In this embodiment, the inner air outlet tube 21 is a soft tube, and the outer air outlet tube 22 is a hard tube. The outer side of the inner air outlet tube 21 is sleeved with a plastic tube 60. The inner side of the inner end of the inner air outlet tube 21 is provided with a solid ring 27 that fits the lip shrinking shape, and the solid ring 27 is elastic. Due to the characteristic that the plastic tube 60 will not be reset after being bent into the required shape, when the inner air outlet tube 21 is bent so that the inner end of the inner air outlet tube 21 covers the mouth, the shape and position of the inner air outlet tube 21 are fixed, so that it can adapt to the facial conditions of different patients and is easy to adjust. Moreover, the solid ring 27 can squeeze the patient's lips into a lip shrinking state, and keep the lip shrinking state when the patient exhales.

[0051] Please also read Figure 7 In this embodiment, the air intake assembly 30 includes an air intake inner tube 31, an air intake outer tube 32 and an impedance plate 33. One end of the air intake outer tube 32 extends through the air outlet 12 to the inside of the mask body 10 and is fixedly connected to the air intake inner tube 31. The inner end of the air intake inner tube 31 is used to be covered on the nose. The impedance plate 33 is fixedly arranged in the air intake outer tube 32. A plurality of through-inhalation holes 36 are opened on the side of the impedance plate 33 close to the air intake inner tube 31. An impedance sheet 34 is covered on the impedance plate 33 and corresponds to each air intake hole 36. The connection between the top side of the impedance sheet 34 and the impedance sheet 33 has a damping resistance, which is used to drive the impedance sheet 34 to cover the air intake hole 36. The impedance sheet 34 is located on the side of the impedance plate 33 close to the air intake inner tube 31. Among them, the area of ​​the impedance sheet 34 is larger than the area of ​​the air intake hole 36, so that the impedance sheet 34 can completely cover and block the air intake hole 36.

[0052] When the patient inhales, the outside air enters the air intake outer tube 32, and then the air enters the air intake hole 36 to squeeze the impedance piece 34, thereby pushing the impedance piece 34 away from the impedance plate 33. At this time, the impedance piece 34 no longer blocks the air from entering the air intake inner tube 31, and the air enters the air intake inner tube 31 and flows into the nasal cavity; when the patient stops inhaling, due to the damping resistance of the top side of the impedance piece 34, the impedance piece 34 is reset and fits on the air intake hole 36 again, thereby preventing the air inside the air intake inner tube 31 from flowing to the air intake outer tube 32, so that the air intake component 30 can only perform the inhalation action.

[0053] Preferably, the air intake inner tube 31 is a hose, the outer side of the air intake inner tube 31 is sleeved with a plastic tube 60, the air intake outer tube 32 is a hard tube, and a nose mask 35 is provided at the inner end of the air intake inner tube 31. Due to the characteristic that the plastic tube 60 will not be reset after being bent into a desired shape, the air intake inner tube 31 maintains the bent shape after the nose mask 35 is covered on the nose.

[0054] Please also read Figure 8In this embodiment, the detection member 40 includes a detection tube 41, a fan 42, a display screen 43 and a detection slide plate 44. The outer wall of the air outlet outer tube 22 is provided with a sliding groove 45 along the length direction. The inner wall of the sliding groove 45 is provided with a receiving groove 46. The length and width of the receiving groove 46 are both larger than the sliding groove 45. The detection slide plate 44 is slidably arranged in the receiving groove 46 for sliding connection. The inner bottom wall of the sliding groove 45 is provided with a plurality of through holes 29 along the length direction. The detection slide plate 44 is provided with a through detection hole 47. One end of the detection tube 41 is fixedly connected to the detection hole 47. The fan 42 is rotatably arranged at the top of the inner part of the detection tube 41. The display screen 43 is arranged on the outer wall of the detection tube 41 for displaying the rotation speed of the fan 42. Among them, displaying the rotation speed of the fan 42 by the display screen 43 in this application is a prior art (referring to the technical means of the anemometer).

[0055] Depending on the position of the through hole 29, the distance that the baffle 231 needs to move in the air outlet outer tube 22 is also different, so the required exhalation intensity is also different. When in use, by pushing the detection slide plate 44 to move in the storage groove 46, the detection hole 47 is connected with the through hole 29 at the corresponding position, so that the exhaled gas enters the detection tube 41 through the detection hole 47. At this time, the exhaled gas flowing in the detection tube 41 will blow the blades of the fan 42, driving the fan 42 to rotate. According to the different rotation speeds of the fan blades, the patient can see the flow rate of the exhaled gas, and at the same time, the patient can also observe whether the exhalation intensity required for training has been reached.

[0056] Preferably, a sealing gasket is provided at the contact point between the detection slide plate 44 and the receiving groove 46. The sealing gasket is used to maintain the sealing between the detection slide plate 44 and the receiving groove 46 to prevent the internal gas of the gas outlet outer pipe 22 from leaking.

[0057] Preferably, a first mark 48 is provided on the outer wall of the air outlet outer tube 22 at a position corresponding to each through hole 29, and a second mark 49 is provided on the detection slide plate 44. When the second mark 49 points to the first mark 48 at the corresponding position, the detection hole 47 is connected to the corresponding through hole 29.

[0058] In this embodiment, the binding member 50 includes two straps 51, one end of each of which is fixedly connected to the two sides of the mask body 10, and the other ends of each of which are wrapped around the back of the head and bonded to the head through Velcro 52. The mask body 10 can be fixedly covered on the face through the binding connection between the two straps 51.

[0059] Working principle of the present invention:

[0060] Before use, push the detection slide plate 44 to move in the storage groove 46 so that the detection hole 47 is connected to the through hole 29 at the corresponding position. When in use, the mask body 10 is placed on the outside of the nose and lips, and the inner outlet tube 21 and the inner inlet tube 31 are bent at the same time, so that the inner end of the inner outlet tube 21 and the inner end of the inner inlet tube 31 are respectively placed on the mouth and nose; then the patient starts to inhale, and the outside air enters the outer inlet tube 32, and then pushes the impedance plate 34 to leave the impedance plate 33. At this time, the impedance plate 34 no longer blocks the air from entering the inner inlet tube 31, and then allows the air to enter the inner inlet tube 31 and flow into the nasal cavity; then the patient begins to purse his lips and exhale, and the exhaled gas passes through the inner outlet tube 21 and enters the outer outlet tube 22, and then squeezes and pushes the baffle 231, so that the baffle 231 moves toward the impedance plate inside the outer outlet tube 22, The outer tube 232 moves in the direction of the anti-exhalation tube 232 until the baffle 231 moves through the through hole 29 at the corresponding position. At this time, the first spring 234 is compressed to generate elastic force, so that the exhaled gas pushes the baffle 231 to move with a certain impedance; at the same time, the movable sensing sheet 24 on the baffle 231 contacts the fixed sensing sheet 25 at the corresponding position, so that the LED light 26 at the corresponding position will emit light and be seen by the patient, reminding the patient to maintain the exhalation intensity at this time; when the exhaled gas flows into the detection tube 41 through the detection hole 47, the exhaled gas will blow the blades of the fan 42, driving the fan 42 to rotate, and the speed of the fan 42 will be displayed on the display screen 43.

[0061] When the initial intensity of the current patient's lip pursing training is lower than the patient's level, the protrusion of the adjusting knob 235 is turned so that the adjusting knob 235 drives the impedance outer tube 232 to rotate, thereby causing the impedance outer tube 232 to move toward the retaining ring 236 inside the air intake outer tube 32. At this time, the first spring 234 is squeezed and contracts, so that the impedance inner tube 233 is initially subjected to the elastic force of the first spring 234 toward the retaining ring 236, thereby increasing the impedance force that the patient is initially subjected to when exhaling.

[0062] The beneficial effects of the present invention are as follows: after the mask body 10 is fixed on the face using the binding member 50, the lip-pursed breathing training device provides a closed environment for the nose and mouth during lip-pursed training; the nose can only be inhaled through the air inlet component 30, and the mouth can only be exhaled through the air outlet mechanism 20, so that the patient can develop the habit of inhaling through the nose and exhaling through the mouth with pursed lips through long-term training, thereby enhancing the rehabilitation effect of lip-pursed breathing; the patient can only exhale through pursed lips through the air outlet mechanism 20, and the impedance of the patient's exhalation is adjusted by the adjustable impedance member 23, so that the patient can reach the exhalation intensity required for training when exhaling; and the rotation speed of the fan 42 enables the patient to see the effect of the lip-pursed training, thereby enhancing the patient's self-confidence in training; at the same time, the LED lamp 26 is used to emit a bright light, so that the patient can see whether the exhalation time has been reached, thereby preventing the patient from losing the motivation for training.
