Description

Technical Field

[0001] This utility model relates to the field of respiratory training equipment technology, and in particular to a respiratory training equipment for respiratory medicine training. Background Technology

[0002] Breathing training is a core intervention in respiratory rehabilitation. It requires training based on standardized breathing rhythms and movement patterns. In some scenarios, it can be combined with breathing training equipment to carry out resistance training. The training focuses on strengthening the respiratory muscle groups such as the diaphragm and intercostal muscles, correcting shallow and rapid chest breathing habits, optimizing the range of chest wall movement, and improving lung ventilation and gas exchange efficiency.

[0003] Currently, the respiratory training devices used in clinical respiratory rehabilitation have relatively limited functions. Most products only support unidirectional expiratory or inspiratory training. If bidirectional respiratory training is required, it is often necessary to change the device, flip the equipment, or manually adjust the valve assembly. The operation process is cumbersome and not conducive to independent use by bedridden patients. In addition, the resistance adjustment weights of traditional devices are mostly independent external accessories, and the storage lacks a reliable limiting structure, making the weights easy to scatter and be lost. Utility Model Content

[0004] The purpose of this invention is to provide a respiratory training device for respiratory medicine training, which can automatically switch between inhalation and exhalation training modes without the need for switching operations. It is equipped with an integrated weight storage structure and can flexibly adjust the training resistance, effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A respiratory training device for respiratory medicine includes a cylinder. A side airway compartment is integrally formed on the outer side of the cylinder. A lower end cover is fixedly installed at the lower end of the cylinder, and an upper end cover is detachably fixedly installed at the upper end of the cylinder. A first sealing seat and a second sealing seat are fixedly installed on the inner bottom surface of the cylinder. A second air intake sealing bag is inserted into the first sealing seat, and a first air intake sealing bag is inserted into the second sealing seat. A third sealing seat is fixedly installed in the side airway compartment near the lower end cover, and a first air outlet sealing bag is inserted into the third sealing seat. A sealing plate is fixedly installed in the upper end cover and extends downward into the cylinder. A perforated plate is fixedly installed below the sealing plate through a connecting pipe, and a second air outlet sealing bag is inserted into the connecting pipe.

[0006] As a further preferred embodiment of this utility model, the cavities inside the cylinder are respectively configured as a weight travel chamber and a weight storage chamber. The weight storage chamber is located above the weight travel chamber, and the inner diameter of the weight storage chamber is larger than the inner diameter of the weight travel chamber, so as to guide the weight to move within the weight travel chamber. The cylinder is provided with an annular guide groove along its inner contour, and the guide groove is connected to the inner cavity of the side air passage chamber.

[0007] As a further preferred embodiment of this utility model, a first shaft frame is fixedly installed inside the first sealing seat, and the guide shaft at the lower end of the second air intake sealing bladder is inserted into the first shaft frame. The second air intake sealing bladder can move vertically inside the first sealing seat, so that when inhaling training, external air pushes open the second air intake sealing bladder and enters the cylinder through the first sealing seat.

[0008] As a further preferred embodiment of this utility model, a second shaft frame is fixedly installed inside the second sealing seat, and the first air intake sealing bag is inserted into the second shaft frame through the guide shaft at the lower end. The first air intake sealing bag can move upward and open during air blowing training, so that the air blown by the user can enter the cylinder.

[0009] As a further preferred embodiment of this utility model, a third shaft frame is fixedly installed inside the third sealing seat, and the guide shaft at the upper end of the first air outlet sealing bladder is inserted into the third shaft frame. A connecting rod is fixedly connected between the first air outlet sealing bladder and the first air inlet sealing bladder, so that during blowing training, the first air inlet sealing bladder opens and the first air outlet sealing bladder closes, and during inhalation training, the first air outlet sealing bladder opens and the first air inlet sealing bladder closes.

[0010] As a further preferred embodiment of this utility model, a connector is fixedly installed on the outer side of the lower end cover, a breathing training tube is fixedly installed on one end of the connector, the lower end cover is connected to the connector and the breathing training tube channel, an air inlet pipe is fixedly installed inside the lower end cover, the upper end of the air inlet pipe abuts against the lower end face of the cylinder, and the inner channel of the air inlet pipe is connected to the inner channel of the first sealing seat.

[0011] As a further preferred embodiment of this utility model, the perforated plate is provided with multiple air holes, which are used to open the first shaft frame by utilizing the negative pressure generated by the user's inhalation during inhalation training, so that external air enters the cylinder through the air inlet pipe and the first sealing seat, and then enters the side airway chamber through the air holes and the guide groove, and then enters the user's lungs through the lower end cover, connector, and breathing training tube.

[0012] As a further preferred embodiment of this utility model, a storage rod is fixedly installed inside the connecting pipe, the storage rod extends into the cylinder, and a limiting block is fixedly installed on the outside of the storage rod. Multiple weights are inserted into the storage rod located below the limiting block. The limiting block restricts the weights from blocking the air vents and connecting pipes during storage. A locking ring is also threaded onto the outside of the storage rod. The locking ring is located below the lowest weight and is used to lock and fix the weights inserted into the storage rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the breathing training modes can be freely switched between inhalation and exhalation to adapt to the different respiratory function rehabilitation training needs of patients, and no manual adjustment or flipping device is required, thus improving the ease of use. Meanwhile, the built-in weight storage structure, through the cooperation of storage rod, limiting block and locking ring, allows the number of weights to be increased or decreased freely according to the patient's recovery progress, and flexibly adjusts the resistance of breathing training. This structure can directly store fixed weights without the need for additional packaging accessories, which not only avoids the problems of weight loss and misalignment blocking the airway, but also greatly improves the portability and practicality of the device.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-4As shown, the present invention provides a respiratory training device for respiratory training, including a cylinder 1, a side airway chamber 2 integrally formed on the outer side of the cylinder 1, a lower end cover 3 fixedly installed at the lower end of the cylinder 1, an upper end cover 4 detachably fixedly installed at the upper end of the cylinder 1, a first sealing seat 12 and a second sealing seat 14 fixedly installed on the inner bottom surface of the cylinder 1 respectively, a second air intake sealing bladder 6 inserted in the first sealing seat 12, a first air intake sealing bladder 5 inserted in the second sealing seat 14, a third sealing seat 16 fixedly installed in the side airway chamber 2 near the lower end cover 3, a first air outlet sealing bladder 7 inserted in the third sealing seat 16, a sealing plate 8 fixedly installed in the upper end cover 4 and extending downward into the cylinder 1, a perforated plate 9 fixedly installed below the sealing plate 8 through a connecting pipe 10, a second air outlet sealing bladder 11 inserted in the connecting pipe 10.

[0018] The cavities inside the cylinder 1 are respectively configured as a weight travel chamber 21 and a weight storage chamber 22. The weight storage chamber 22 is located above the weight travel chamber 21, and the inner diameter of the weight storage chamber 22 is larger than the inner diameter of the weight travel chamber 21, so as to guide the weight 28 to move within the weight travel chamber 21. An annular guide groove 23 is formed along the inner contour of the cylinder 1, and the guide groove 23 is connected to the inner cavity of the side air passage chamber 2. A first shaft bracket 13 is fixedly installed inside the first sealing seat 12, and the guide shaft at the lower end of the second air inlet sealing bladder 6 is inserted and installed inside the first shaft bracket 13. The second air intake sealing bladder 6 can move vertically within the first sealing seat 12. During inhalation training, external air pushes open the second air intake sealing bladder 6 and enters the cylinder 1 through the first sealing seat 12. A second shaft bracket 15 is fixedly installed inside the second sealing seat 14. The first air intake sealing bladder 5 is inserted into the second shaft bracket 15 through a guide shaft at its lower end. During exhalation training, the first air intake sealing bladder 5 can move upward to open, allowing the air blown out by the user to enter the cylinder 1. A third shaft bracket 17 is fixedly installed inside the third sealing seat 16. The first air outlet sealing... The guide shaft at the upper end of the bladder 7 is inserted into the third shaft bracket 17. A connecting rod 29 is fixedly connected between the first exhaust sealing bladder 7 and the first intake sealing bladder 5, so that during blowing training, the first intake sealing bladder 5 opens and the first exhaust sealing bladder 7 closes; during inhalation training, the first exhaust sealing bladder 7 opens and the first intake sealing bladder 5 closes. A connector 18 is fixedly installed on the outside of the lower end cover 3. A breathing training tube 19 is fixedly installed at one end of the connector 18. The lower end cover 3 is connected to the connector 18 and the breathing training tube 19. A connecting rod 29 is fixedly installed inside the lower end cover 3. There is an air inlet pipe 20, the upper end of which abuts against the lower end face of the cylinder 1, and the inner channel of the air inlet pipe 20 is connected to the inner channel of the first sealing seat 12. Multiple air holes 24 are opened in the perforated plate 9, which are used to open the first shaft frame 13 by using the negative pressure generated by the user's inhalation during inhalation training, so that the external air enters the cylinder 1 through the air inlet pipe 20 and the first sealing seat 12, and enters the side airway chamber 2 through the air holes 24 and the guide groove 23, and then enters the user's lungs through the lower end cover 3, the connector 18, and the breathing training tube 19.

[0019] A storage rod 25 is fixedly installed inside the connector 10. The storage rod 25 extends into the cylinder 1, and the guide shaft at the lower end of the second vent sealing bladder 11 is inserted into the channel inside the storage rod 25. A limiting block 26 is fixedly installed on the outside of the storage rod 25. Multiple weights 28 are inserted into the storage rod 25 located below the limiting block 26. The limiting block 26 restricts the weights 28 so that they do not block the air hole 24 or the connector 10 during storage. A locking ring 27 is also threaded onto the outside of the storage rod 25. The locking ring 27 is located below the lowest weight 28 and is used to lock and fix the weights 28 inserted into the storage rod 25.

[0020] It should be noted that this utility model is a respiratory training device for respiratory medicine training. During exhalation training, the user holds the breathing training tube 19 and places the sealing cover at the end of the breathing training tube 19 over their mouth. Then, the user blows air into the breathing training tube 19. The airflow then enters the lower end cap 3 through the breathing training tube 19 and pushes the first outlet sealing bladder 7 upward, so that the upper part of the first outlet sealing bladder 7 abuts against the third sealing seat 16. At the same time, it pushes the first inlet sealing bladder 5 upward, thereby causing the lower part of the first inlet sealing bladder 5 to detach from the inner wall of the second sealing seat 14. The first exhaust sealing bladder 7 and the first intake sealing bladder 5 move together with the connecting rod 29 to prevent the airflow entering the cylinder 1 from flowing back into the side air passage chamber 2 through the air hole 24 and the guide groove 23, thus opening the first exhaust sealing bladder 7. As a result, the airflow entering the cylinder 1 blows air onto the weight 28 and moves it upward in the weight travel chamber 21. At the same time, some airflow rises along the gap between the weight 28 and the inner wall of the weight travel chamber 21 and finally enters the connecting pipe 10, opening the second exhaust sealing bladder 11 upward, so that it can be discharged through the hole at the top of the upper end cover 4, thereby realizing the exhalation training.

[0021] During inhalation training, the user only needs to switch from exhalation to inhalation. The negative pressure generated by the user's inhalation is guided into the cylinder 1 through the third sealing seat 16, the side airway chamber 2, the guide groove 23, and the air hole 24. This negative pressure also attracts the weight 28 upward into the weight travel chamber 21. At the same time, the second air intake sealing bladder 6 opens upward using the negative pressure, allowing external air to enter the cylinder 1 through the air intake pipe 20 and the first sealing seat 12. Finally, the air enters the user's lungs through the air hole 24, the guide groove 23, the side airway chamber 2, the lower end cover 3, the connector 18, and the breathing training tube 19, thus completing the inhalation training.
