Description

Technical Field

[0001] This utility model relates to the field of COPD lip pursing exercise technology, specifically a COPD lip pursing exercise device. Background Technology

[0002] Patients with chronic obstructive pulmonary disease (COPD) often experience incomplete exhalation, leading to a vicious cycle where residual air is not completely exhaled, ultimately causing emphysema due to the accumulation of air in the alveoli. Pursed-lip breathing creates pressure clamps within the trachea and bronchi, preventing the collapse of the bronchioles caused by loss of radiative traction and intrathoracic pressure. It is suitable for patients with severe COPD who often experience bronchospasm, panic, or overinflation of the lungs during exercise. It can also be used as an adjunct measure for patients undergoing exercise rehabilitation or respiratory muscle training, with no contraindications. The basic method is as follows: Inhale through the nose with the mouth closed, and exhale slowly through pursed lips (slightly pursed-lip breathing), while simultaneously contracting the abdomen. The ratio of inhalation to exhalation time should be 1:2 or 1:3. Aim for deep, slow inhalation and exhalation, with the pursing of the lips done without feeling strenuous. Practice twice daily for 10-20 minutes each time, at a rate of 7-8 repetitions per minute.

[0003] Chinese utility model patent CN212439922U discloses a pursed-lip breathing exercise device for COPD, including an air cup and an air tube.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-9This utility model discloses a COPD pursed-lip exercise device, including an air inlet tube 1, a one-way valve 2, and an air cup 3. The one-way valve 2 is fixedly connected to one end of the air inlet tube 1, and the other end of the one-way valve 2 is fixedly connected to a bend tube 4. The air cup 3 is threadedly connected to the bend tube 4. A battery box 5 for installing batteries and a display screen 6 are fixedly connected to the surface of the air cup 3.

[0028] Specifically, the fixing structure includes connecting brackets 7 symmetrically arranged on both sides of the air tube 1. Each connecting bracket 7 has a slot 8, and a connecting rod 9 is movably connected inside the slot 8. A limiting ring 10 is fixedly connected to the surface of the connecting rod 9, and the surface of the limiting ring 10 is movably connected to the surface of the connecting bracket 7. A tightening strap 11 is detachably installed on the surface of the connecting rod 9, and a fastening component is fixedly connected to the end of the tightening strap 11. The fastening component can be Velcro or a buckle; alternatively, the fastening component can be omitted, and the device can be directly secured by the tightening strap.

[0029] In this implementation plan, for ease of use, the training device can be wrapped around the face and fixed at the back of the head without having to hold it with your hands. It can be fixed with Velcro or buckles, or it can be tied directly.

[0030] Specifically, a fixing ring 12 is fixedly connected to the surface of the connecting rod 9, and a pull rod 13 is movably connected inside the fixing ring 12. A connecting piece 14 is movably sleeved on the surface of the pull rod 13, and the tightening strap 11 is fixed to the surface of the connecting piece 14. A pull lug 15 is fixedly connected to the bottom of the pull rod 13, and a through hole 16 is opened at the top of the pull rod 13. A relief groove 17 connected to the through hole 16 is provided from top to bottom at the top of the pull rod 13, and the inner sidewall of the through hole 16 is movably connected to a U-shaped soft metal strip 18.

[0031] In this embodiment, in order to remove the training device as soon as possible, the patient can pull the lever 13 by pulling the ear 15, which will stretch and deform the U-shaped soft metal strip 18, and make room for the metal in the groove 17, thereby facilitating the movement of the lever 13. After detachment, the connector 14 can be separated from the fixing ring 12, and the training device can be automatically detached.

[0032] Specifically, the surface of the limiting ring 10 is provided with a positioning groove 19, the inner wall of the positioning groove 19 is movably connected to the surface of the U-shaped rod 20, the surface of the U-shaped rod 20 is movably connected to the inner wall of the slot 8, and the surface of the U-shaped rod 20 is fixedly connected with a pressing protrusion 21, which is disposed away from the connecting rod 9.

[0033] In this embodiment, the U-shaped rod 20 can be pulled directly, and the extrusion protrusion 21 on the U-shaped rod 20 will extrude the connecting rod 9, thereby disengaging the connecting rod 9 from the slot 8, which can also be used in an emergency.

[0034] Specifically, the internal detection structure includes an airflow sensor 22, which is fixedly connected inside the air cup 3. The air cup 3 is threadedly connected to the surface of the bent tube 4, and the surface of the bent tube 4 is provided with a flow groove 23. A return spring 24 is fixedly connected inside the air cup 3, and the other end of the return spring 24 is fixedly connected to the sealing cover 25. The surface of the sealing cover 25 is movably connected to the end of the bent tube 4. A temperature sensor 26 and a humidity sensor 27 are fixedly connected to the surface of the sealing cover 25. An infrared sterilizer 28 is also fixedly connected to the surface of the sealing cover 25.

[0035] In this embodiment, a temperature sensor 26 and a humidity sensor 27 are arranged inside the air cup 3 to detect the temperature and humidity inside the air cup 3 in real time. Since the air contains moisture during blowing, prolonged use may lead to excessive moisture inside the air cup 3, causing bacterial growth. When the humidity sensor 27 detects excessive humidity, the infrared sterilizer 28 will activate to perform heating sterilization. At this time, the display screen can show a message indicating that use is not recommended according to a pre-set program. During the heating process, the temperature sensor 26 can monitor the temperature in real time to prevent overheating.

[0036] Specifically, the resistance adjustment structure includes a filter screen 29 and a threaded cap 30. The filter screen 29 is fixedly connected inside the threaded cap 30, which is threadedly connected to the top of the air cup 3. The surface of the threaded cap 30 is provided with an air vent groove 31. The surface of the threaded cap 30 is provided with a snap-fit ​​ring groove 32, and the threaded cap 30 is movably connected to a rotating hole cap 33 through the snap-fit ​​ring groove 32. A conical hole cover 34 is fixedly connected to the top of the rotating hole cover 33, and a gas flow rate sensor 35 is fixedly connected inside the conical hole cover 34.

[0037] In this embodiment, the conical orifice cover 34 is transparent, and the internal rotating orifice cover 33 can be seen. By rotating the conical orifice cover 34, the rotating orifice cover 33 can be driven synchronously. The rotating orifice cover 33 can block part of the ventilation groove 31, thereby adjusting the air outlet resistance. The filter screen 29 can prevent external dust from entering the interior of the air cup 3 through the ventilation groove 31.

[0038] Specifically, the air cup 3 is internally connected to a fixed frame 36, and the surface of the fixed frame 36 is fixedly connected to an absorbent cotton 37.

[0039] In this embodiment, the air cup 3 is also provided with a fixing frame 36, and a water-absorbing cotton 37 is fixed on the fixing frame 36. The water-absorbing cotton 37 can absorb water vapor, and the infrared sterilizer 28 can heat and dry the water-absorbing cotton during the sterilization process.

[0040] The working principle and usage of this utility model are as follows: During use, the patient places the air tube 1 into their mouth. The air tube 1 is equipped with a bite ring and a soft stop. The patient can bite down on the bite ring, and the soft stop rests against the patient's mouth. For ease of use, eliminating the need to constantly hold the training device, the restraint strap 11 can be wrapped around the face and secured at the back of the head. This can be done using Velcro or buckles, or simply by tying it on.

[0041] The patient blows air through the inhalation tube 1. A one-way valve 2 ensures that air can only enter and not exit. After the airflow enters the inhalation cup 3, the gas flows. The airflow sensor 22 detects the airflow, and the counter built into the display screen 6 starts timing, showing the time. The gas eventually exits through the conical orifice hood 34. The gas flow rate sensor 35 detects the gas flow rate, which is also displayed on the display screen 6. The patient can adjust their exhalation force based on real-time data.

[0042] The conical orifice cover 34 is transparent, allowing a view of the internal rotating orifice cover 33. Rotating the conical orifice cover 34 synchronously drives the rotating orifice cover 33, which partially blocks the ventilation slot 31, thereby adjusting the airflow resistance. The filter screen 29 prevents external dust from entering the air cup 3 through the ventilation slot 31. A temperature sensor 26 and a humidity sensor 27 are arranged inside the air cup 3 to monitor the internal temperature and humidity in real time. Since the air contains moisture during blowing, prolonged use may lead to excessive moisture inside the air cup 3, causing bacterial growth. When the humidity sensor 27 detects excessive humidity, the infrared sterilizer 28 will activate for heating and sterilization. At this time, the display screen can show a warning against use based on a pre-set program. During the heating process, the temperature sensor 26 monitors the temperature in real time to prevent overheating.

[0043] Additionally, the air cup 3 has a mounting bracket 36 inside, on which absorbent cotton 37 is fixed. The absorbent cotton 37 can absorb moisture, and the infrared sterilizer 28 can heat and dry the absorbent cotton during the sterilization process. Patients or their families can periodically unscrew the threaded cap 30 to remove and replace the absorbent cotton 37.

[0044] The air cup 3 and the bend 4 are connected by threads. After the air cup 3 is unscrewed, the sealing cover 25 will automatically reset under the action of the return spring 24, blocking the air cup 3 and preventing external impurities from entering.

[0045] It should also be noted that when the gas flow sensor 35 detects a sudden increase in flow rate, followed by a sudden decrease, and then a sudden increase again, it can be determined that the patient is experiencing a rapid cough, and the built-in alarm in the display 6 will sound. To remove the training device as quickly as possible, the patient can pull the lever 13 by pulling the lug 15, which will deform the U-shaped soft metal strip 18, allowing the groove 17 to accommodate the metal and facilitate the movement of the lever 13. After detachment, the connector 14 can disengage from the fixing ring 12, and the training device can automatically detach. Alternatively, the U-shaped rod 20 can be pulled directly; the pressing protrusion 21 on the U-shaped rod 20 will press against the connecting rod 9, disengaging the connecting rod 9 from the slot 8, which can also be used in an emergency.
