Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a respiratory medicine clinical lung capacity training device. Background Technology

[0002] Lung capacity training is a common rehabilitation method in respiratory medicine. It primarily involves specific breathing exercises (such as diaphragmatic breathing and pursed-lip breathing) or the use of breathing machines to help patients strengthen their respiratory muscles and improve lung ventilation efficiency, thereby increasing lung capacity and gas exchange capacity. This training is suitable for patients with chronic obstructive pulmonary disease, postoperative lung function recovery, asthma, etc. It can effectively relieve shortness of breath, improve exercise tolerance, and promote sputum expectoration. Training should be conducted gradually under professional guidance, with intensity adjusted according to individual circumstances. Long-term adherence can significantly improve quality of life and reduce the risk of acute exacerbations.

[0003] Existing lung capacity training devices are simple in function, only collecting exhaled air through a damping structure. However, the duration of inhalation and exhalation is also an important indicator of training. Usually, due to poor lung capacity in the early stage and hyperventilation, dizziness and blurred vision are likely to occur during training. Improper training can also easily lead to respiratory alkalosis, making it difficult to carry out regular and stable breathing training. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing lung capacity training equipment has a simple structure and function, and provides little help for breathing training during lung capacity training. In view of the problems existing in the prior art, a clinical lung capacity training device for respiratory medicine is provided.

[0005] The purpose and effect of this utility model are achieved by the following specific technical means: including a machine box and a breathing seat, the breathing seat is disposed outside the machine box, and a nasal tube groove and a mouth tube are formed on the breathing seat, and an external air tube with an outlet end and an inlet end is passed through the end of the nasal tube groove and the mouth tube between them and the machine box.

[0006] The machine box has an exhalation chamber and an inhalation chamber fixed on both sides. The inhalation chamber is directly connected to an inhalation valve tube that is connected to the outlet end of the external air tube. The valve port of the inhalation valve tube is controlled by a solenoid valve. The exhalation chamber is connected to an interface valve. One end of the interface valve is connected to an exhalation valve tube that is connected to the inlet end of the external air tube. The other end of the interface valve is connected to a first inflation tube. A second inflation tube is symmetrically arranged on one side of the first inflation tube. A three-way valve is connected between the first inflation tube and the second inflation tube. The air volume between the first inflation tube, the second inflation tube, and the three-way valve is constant. A stopper plate with a position matching the air volume is slidably arranged in the first inflation tube and the second inflation tube. The bottom and top of the second inflation tube are provided with switch contacts that cooperate with the stopper plate. An inflation ball is connected to the second inflation tube.

[0007] The control panel is embedded in the chassis.

[0008] Furthermore: the mouth tube is a slender conical tube, and the nasal tube groove is an externally enclosed nasal groove.

[0009] A further preferred embodiment: the air intake chamber is connected to an air inlet pipe, and a suction fan assembly is embedded between the air inlet pipe and the outer wall of the casing.

[0010] A further preferred embodiment: a filter bag is provided through the air intake pipe and the suction fan assembly.

[0011] A further preferred embodiment: one end of the three-way valve is connected to a piston shaft tube, and the piston shaft end of the piston shaft tube is driven by a micro motor. The piston shaft tube changes the volume of the cavity between itself and the three-way valve through axial piston movement.

[0012] A further preferred embodiment: the valve port of the interface valve has a pneumatic valve leaf structure, and the opening and closing direction of the valve leaf is located inward at the port end connected to the exhalation chamber.

[0013] The beneficial effects of this utility model are:

[0014] This respiratory medicine clinical vital capacity training device limits expiratory volume by restricting the lumen capacity through two opposing inflation tubes. It prompts trainees to inhale and exhale by closing the expiratory tube and opening and closing the inspiratory tube in corresponding states. The tube structure uses a constant volume of air to cycle through inflation, resetting, and inflation, allowing trainees to perform isometric inhalation and exhalation training. This avoids the problems of poor training effect and overtraining that traditional training devices rely solely on the patient's self-judgment of breathing, thus improving the training effect and safety of this device.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the following description is provided in conjunction with the accompanying drawings. Figures 1-4 The present invention will be further described in detail below with specific embodiments. The following embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any modifications and refinements made without departing from the scope of the present invention are within the patent protection scope of the present invention.

[0022] A respiratory medicine clinical vital capacity training device includes a housing 1 and a breathing seat 2. The breathing seat 2 is disposed outside the housing 1, and a nasal tube groove 4 and a mouth tube 5 are formed on the breathing seat 2. An external trachea 6, which is divided into an outlet end and an inlet end, is inserted between the end of the nasal tube groove 4 and the mouth tube 5 and the housing 1.

[0023] The casing 1 has an exhalation chamber 12 and an inhalation chamber 13 fixed on both sides. The inhalation chamber 13 is directly connected to an inhalation valve tube 8 that is connected to the outlet end of the external air tube 6. The valve port of the inhalation valve tube 8 is controlled by a solenoid valve. The exhalation chamber 12 is connected to an interface valve 18. One end of the interface valve 18 is connected to an exhalation valve tube 7 that is connected to the inlet end of the external air tube 6. The other end of the interface valve 18 is provided with a first inflation tube 9. A second inflation tube is symmetrically arranged on one side of the first inflation tube 9. An inflation tube 10 is provided, and a three-way valve 11 is provided between the first inflation tube 9 and the second inflation tube 10. The air volume between the first inflation tube 9, the second inflation tube 10 and the three-way valve 11 is constant. A stopper plate 19 with a position matching the air volume is slidably provided in the first inflation tube 9 and the second inflation tube 10. Switch contacts 20 that press against the stopper plate 19 are provided at the bottom and top of the second inflation tube 10. An inflation ball 21 is connected to the second inflation tube 10.

[0024] The control panel 3 is embedded in the box 1;

[0025] The device uses a breathing seat 2 connected by a tube as a gripping structure for patients during training. The breathing seat 2 has a nasal tube groove 4 and a mouth tube 5 for the patient's nose and mouth to align. During training, patients can perform synchronous training by exhaling through their mouth and inhaling through their nose.

[0026] Under normal conditions, the valve of the inhalation chamber 13 is relatively closed. At this time, the patient exhales to inflate the first inflation tube 9 through the external trachea 6 and the exhalation valve tube 7. During the inflation process, the air pressure will push the stopper 19 downward to compress the gas in the first inflation tube 9, and continuously push the gas into the second inflation tube 10 through the three-way valve 11. The expansion of the gas at the bottom of the second inflation tube 10 is used to push the stopper 19 in the second inflation tube 10. Finally, the stopper 19 is pressed to the top of the second inflation tube 10 and contacts the switch contact 20. The gas stored in the second inflation tube 10 is collected by the inflation of the inflation ball 21. At this time, the inflation volume in the entire exhalation line reaches the maximum, making it difficult to exhale. The electrical signal of the switch contact 20 pressing down will open the valve of the inhalation chamber 13. The patient can inhale through the nasal tube slot 4 by judging the state of difficulty in exhaling. The inhalation chamber 13 and the inhalation valve tube 8 provide air to the patient.

[0027] Furthermore, after exhalation stops, the inflatable ball 21, no longer subject to the air pressure at the inflation end, will elastically reset, and during the reset, the gas inside will be squeezed back into the second inflation tube 10. During this process, the downward movement of the stopper 19 will reset the position of the stopper 19 of the first inflation tube 9 through air pressure. When the stopper 19 is reset, the gas inhaled by the patient in the first inflation tube 9 will close the valve port of the interface valve 18 in the counter-current direction. At this time, the inhaled gas can pass through the interface valve 18 to the exhalation chamber 12 to empty the first inflation tube 9 and reset the position of the stopper 19 until the switch contact 20 at the bottom of the second inflation tube 9 is connected to the stopper 19, thereby closing the valve port of the inhalation chamber 13 to provide the patient with a indication of the difficulty in inhaling. Then, a second exhalation is performed, and the cycle repeats.

[0028] The device provides patients with equal exhalation and inhalation space through a constant air volume cavity in the first inflation tube 9 and the second inflation tube 10, and a stopper disc 19 structure that matches the air volume, which facilitates patients to perform periodic breathing training. This tubing structure makes it easy to control the patient's respiratory rate and ventilation duration, thereby improving the training effect of the device.

[0029] Based on the above, the mouth tube 5 is a slender conical tube, and the nasal tube slot 4 is an externally covered nasal slot. The mouth tube 5 is a slender conical tube, which makes it convenient for patients to train using the locked-lip breathing method and reduces the error between the exhalation volume and the inhalation volume.

[0030] Furthermore, the inhalation chamber 13 is connected to an air inlet pipe 14, and a suction fan assembly is embedded between the air inlet pipe 14 and the outer wall of the casing 1. The inhalation chamber 13 is filled with air along the air inlet pipe 14 by braking the suction fan assembly, providing stable air volume support for the patient's inhalation action. At the same time, the oxygen supply effect can be improved by connecting an oxygen generator to the air inlet pipe 14.

[0031] Furthermore, a filter bag 15 is installed between the air intake pipe 14 and the suction fan assembly. The air entering the air intake chamber 13 is filtered by the filter bag 15 with a custom mesh size to ensure the purity of the air and improve the user experience.

[0032] Furthermore, one end of the three-way valve 11 is connected to a piston shaft tube 17, and a micro motor 16 is driven and coupled to the piston shaft end of the piston shaft tube 17. The piston shaft tube 17 changes the volume of the cavity between itself and the three-way valve 11 through axial piston movement, such as... Figure 4 As shown, the trainee can control the micro motor 16 via the switch on the control panel 3. The micro motor 16 brakes and drives the piston shaft tube 17 to make relative axial piston displacement along the tube body. During this period, the axial movement of the piston shaft will change the size of the tube body cavity, that is, change the capacity of the three-way valve 11 pipeline. By changing the volume of air passing through, the inflation capacity between the first inflation tube 9 and the second inflation tube 10 is changed. That is, the air volume ratio of the stopper disc 19 in the second inflation tube 10 to the top when the patient exhales is adjusted, thereby prolonging / shortening the entire exhalation time. The adjustment is made according to the actual training plan.

[0033] Furthermore, the valve port of the interface valve 18 has a pneumatic valve leaf structure, and the opening and closing direction of the valve leaf of the interface valve 18 is located inward at the end of the pipe connected to the exhalation chamber 12, such as... Figure 4 As shown, the opening and closing positions of the valve leaf correspond to the ventilation state. When air enters the exhalation valve tube 7, the valve leaf is relatively pressed against the valve port of the interface valve 18. When the first inflation tube 9 vents air into the exhalation valve tube 7, the valve leaf position will be changed by the air pressure to close the valve leaf at the port of the exhalation valve tube 7, so that the gas in the first inflation tube 9 enters the exhalation chamber 12 along the interface valve 18.

[0034] During training, the patient holds the breathing seat 2 to align the nose and mouth on the nasal tube groove 4 and mouth tube 5, and performs synchronous training by exhaling through the mouth and inhaling through the nose.

[0035] Under normal conditions, the valve of the inhalation chamber 13 is relatively closed. At this time, the patient exhales to inflate the first inflation tube 9 through the external trachea 6 and the exhalation valve tube 7. During the inflation process, the air pressure will push the stopper 19 downward to compress the gas in the first inflation tube 9, and continuously push the gas into the second inflation tube 10 through the three-way valve 11. The expansion of the gas at the bottom of the second inflation tube 10 is used to push the stopper 19 in the second inflation tube 10. Finally, the stopper 19 is pressed to the top of the second inflation tube 10 and contacts the switch contact 20. The gas stored in the second inflation tube 10 is collected by the inflation of the inflation ball 21. At this time, the inflation volume in the entire exhalation line reaches the maximum, making it difficult to exhale. The electrical signal of the switch contact 20 pressing down will open the valve of the inhalation chamber 13. The patient can inhale through the nasal tube slot 4 by judging the state of difficulty in exhaling. The inhalation chamber 13 and the inhalation valve tube 8 provide air to the patient.

[0036] After exhalation stops, the inflatable ball 21, no longer subject to the air pressure at the inflation end, will elastically reset, and during the reset, the gas inside will be squeezed back into the second inflation tube 10. During this process, the downward movement of the stopper 19 will reset the position of the stopper 19 of the first inflation tube 9 through air pressure. When the stopper 19 is reset, the gas inhaled by the patient in the first inflation tube 9 will close the valve port of the interface valve 18 in the counter-current direction. At this time, the inhaled gas can pass through the interface valve 18 to the exhalation chamber 12 to empty the first inflation tube 9 and reset the position of the stopper 19 until the switch contact 20 at the bottom of the second inflation tube 9 is connected to the stopper 19, thereby closing the valve port of the inhalation chamber 13, providing the patient with a indication of the difficulty in inhaling, and then a second exhalation is performed, and the cycle repeats.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
