Description

Technical Field

[0001] The utility model relates to the technical field of respiratory training devices, in particular to a respiratory training device. Background Art

[0002] Breathing refers to the process of gas exchange between the body and the external environment. The human respiratory process consists of three interconnected links: external respiration, including pulmonary ventilation and gas exchange; gas transport in the blood; and internal respiration, which refers to the gas exchange between tissue cells and the blood. A normal, resting adult's breathing interval is optimally 6.4 seconds. The lungs are both respiratory organs and important hematopoietic organs in the human body. They are located in the chest cavity, one on each side, covering the heart. During pulmonary function rehabilitation training, a pulmonary function rehabilitation trainer is required to train lung function breathing to facilitate lung function recovery.

[0003] Chinese utility model CN218553036U describes a breathing trainer with easily replaceable tubing. This design features a removable tubing to prevent internal bacterial growth from repeated use. The device utilizes a filter box at the interface to filter impurities. A connector is also located on one side of the filter box. To install the device, one end of the tubing is inserted into the connector, and then the electromagnetic coil is connected to an external power source. This increases the magnetic force, drawing the magnetic block inside the movable slot into the slot and into contact with the electromagnetic coil, thereby securing the tubing and preventing it from being removed from the connector, thus completing installation.

[0004] However, when using existing devices, inserting one end of the pipe into the connector requires rotating the pipe to align the movable groove on the pipe with the internal slot of the connector. Furthermore, the movable groove and the internal slot are not directly visible, requiring multiple attempts to align the movable groove and the internal slot. This also makes it difficult to insert the magnetic block into the internal slot to complete installation, making it inconvenient to use. Therefore, a breathing training device with easier installation has been designed to address the above issues. Utility Model Content

[0031] Breathing refers to the process of gas exchange between the body and the external environment. The human respiratory process consists of three interconnected links: external respiration, including pulmonary ventilation and gas exchange; gas transport in the blood; and internal respiration, which refers to the gas exchange between tissue cells and the blood. A normal, resting adult's breathing interval is optimally 6.4 seconds. The lungs are both respiratory organs and important hematopoietic organs in the human body. They are located in the chest cavity, one on each side, covering the heart. During pulmonary function rehabilitation training, a pulmonary function rehabilitation trainer is required to train lung function breathing to facilitate lung function recovery.

[0032] In the related art, a filter box is provided at the interface of the breathing trainer to filter impurities. At the same time, a connection seat is designed on one side of the filter box. When installation is required, one end of the pipe can be inserted into the connection seat and then the electromagnetic coil is connected to the external power supply. The magnetic force is increased to suck the magnetic block inside the movable groove into the slot and fit with the electromagnetic coil, thereby restricting the pipe and making it impossible to pull the pipe out of the connection seat, thus completing the installation. However, when using the existing device, when inserting one end of the pipe into the connection seat, the pipe needs to be rotated to align the movable groove on the pipe with the slot inside the connection seat. The movable groove and the slot are designed to be invisible from the inside, and multiple attempts are required to align the movable groove and the slot, so that the magnetic block is inserted into the slot to complete the installation, which is inconvenient to use.

[0033] To address the problems in the related art to a certain extent, an embodiment of the present application provides a breathing training device. When the air tube 14 needs to be installed on the breathing training device body 11, one end of the air tube 14 can be inserted into the interior of the connecting pipe 13 and finally into the interior of the filter box 12. When entering the interior of the filter box 12, the end of the air tube 14 will contact the block 24. Because one side of the block 24 is designed with an inclined surface, when the end of the air tube 14 contacts the block 24, the block 24 is squeezed to one side. The plate 23 pushes the pull rod 22 out of the interior of the filter box 12, and the spring 1 25 is compressed until the end of the block 24 is aligned with the slot 21 on the air tube 14. The spring 1 25 rebounds and pushes the plate 23 to move, so that the block 24 engages with the slot 21, thereby preventing the end of the air tube 14 from being withdrawn from the interior of the connecting pipe 13. Thus, the installation of the air tube 14 is completed. When disassembly is required, the pull rod 22 is simply pulled to separate the clamping block 24 from the clamping slot 21 and release the restriction on the air pipe 14 , so that the air pipe 14 can be pulled out from the inside of the connecting pipe 13 for disassembly.

[0034] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0035] Combine Figures 1-4 The embodiment of the present application provides a breathing training device, comprising: a breathing trainer main body 11 with a filter box 12 provided at its top interface; a connecting pipe 13 fixedly arranged on one side of the filter box 12; one end of the air pipe 14 is inserted into the interior of the connecting pipe 13; a locking assembly 2 is provided inside the filter box 12, and the locking assembly 2 comprises: a slot 21 opened on the outer wall of one end of the air pipe 14; one end of a pull rod 22 is inserted into the interior of the filter box 12; a plate body 23 fixedly arranged at one end of the pull rod 22; a blocking block 24 is arranged on one side of the plate body 23 and engaged with the slot 21; a spring 25 is sleeved on the outer wall of the pull rod 22, and its two ends are connected to the inner wall of the filter box 12 and the plate body 23.

[0036] Specifically, the respiratory trainer body 11 is a three-balloon respiratory trainer. The principle of the three-balloon respiratory trainer is to stimulate and improve the function of the respiratory muscles and promote lung expansion by simulating deep breathing, thereby maintaining a clear airway and preventing incomplete lung expansion. This trainer performs resistance breathing training by adjusting different resistance levels, helping to improve the chest cavity's ability to contract and expand, significantly increasing vital capacity. Specifically, the three-balloon respiratory trainer consists of three cylinders engraved with air flow rates, with the ball inside each cylinder representing the corresponding flow rate. The trainer is equipped with an exhalation training valve and an inhalation training valve, which respectively control the resistance of exhalation and inhalation. It also has a respiratory trainer tube and a mouthpiece, making it easy to use. The filter box 12 is equipped with an activated carbon plate to adsorb bacteria in the air. The activated carbon plate is prior art and is not shown in the figure.

[0037] When the air tube 14 needs to be installed on the breathing trainer body 11 during use, one end of the air tube 14 can be inserted into the interior of the connecting pipe 13 and finally into the interior of the filter box 12. When entering the interior of the filter box 12, one end of the air tube 14 will contact the block 24. Because one side of the block 24 is designed with an inclined surface, when the one end of the air tube 14 contacts the block 24, the block 24 is squeezed and moved to one side. The plate 23 pushes the pull rod 22 out of the interior of the filter box 12 and the spring 1 25 is compressed until one end of the block 24 is aligned with the slot 21 on the air tube 14. The spring 1 25 rebounds and pushes the plate 23 to move, so that the block 24 engages with the slot 21, thereby preventing the one end of the air tube 14 from being withdrawn from the interior of the connecting pipe 13. Thus, the installation of the air tube 14 is completed. When disassembly is required, the pull rod 22 is simply pulled to separate the clamping block 24 from the clamping slot 21 and release the restriction on the air pipe 14 , so that the air pipe 14 can be pulled out from the inside of the connecting pipe 13 for disassembly.

[0038] In some embodiments, the inner wall of the connecting tube 13 is in contact with the outer wall of one end of the trachea 14 .

[0039] During use, the inner wall of the connecting tube 13 fits against the outer wall of one end of the air tube 14 to reduce the gap, thereby reducing air leakage during blowing and ensuring the sealing of the installation.

[0040] In some embodiments, the locking assembly 2 further includes a pull rod 26 disposed at one end of the pull rod 22 .

[0041] The design of the pull knob 26 is convenient for gripping during use, and the pull rod 22 is not easy to slip when the pull knob 26 is controlled to pull it out from the interior of the filter box 12 .

[0042] In some embodiments, the engaging assembly 2 further includes a guide ring 27 disposed at one end of the air pipe 14 .

[0043] When in use, the outer wall of the guide ring 27 is designed to be inclined, and the inclination angle is consistent with the inclination angle of the inclined surface of the block 24, so it can fit better when in contact with the block 24, reducing scratches generated during contact.

[0044] In some embodiments, the locking assembly 2 further includes a retaining ring 28 fixedly sleeved on the outer wall of the trachea 14 .

[0045] The design of the retaining ring 28 during use can limit the length of the air pipe 14 inserted into the connecting pipe 13, preventing the block 24 from being separated from the slot 21 due to being inserted too deep, and stabilizing the position of the block 24.

[0046] In some embodiments, the locking assembly 2 further includes a sealing ring 29 disposed on one side of the retaining ring 28 .

[0047] The design of the sealing ring 29 can seal one end of the connecting pipe 13 during use, thereby improving the sealing effect after installation.

[0048] In some embodiments, a telescopic assembly 3 is symmetrically arranged on the outer wall of the filter box 12, and the telescopic assembly 3 includes: a tube body 31 arranged on the outer wall of the filter box 12; a second spring 32 arranged inside the tube body 31; one end of an inner rod 33 is inserted into the interior of the tube body 31 and connected to one end of the second spring 32.

[0049] During use, when the trachea 14 is installed, the retaining ring 28 will push the inner rod 33 back into the inside of the tube body 31, and at the same time squeeze the spring 2 32 to compress it, until the restriction on the trachea 14 is released when it is disassembled, and the spring 2 32 rebounds and pushes the inner rod 33 out from the inside of the tube body 31 while pushing the retaining ring 28 to move so that one end of the trachea 14 is pulled out from the inside of the connecting pipe 13.

[0050] In some embodiments, the telescopic assembly 3 further includes a rubber block 34 disposed at one end of the inner rod 33 .

[0051] The design of the rubber block 34 and its soft material make it difficult to scratch when in contact with the retaining ring 28 during use.

[0052] In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.

[0053] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0054] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
