Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a breathing training mouthpiece that prevents aspiration. Background Technology

[0002] In daily life, unhealthy habits such as prolonged sitting, poor posture, and lack of exercise can lead to the degeneration of respiratory muscles, thus affecting their health. Therefore, in addition to providing respiratory rehabilitation training for patients with chronic respiratory diseases, lung diseases (such as emphysema, COPD, etc.), or those who have undergone lung surgery, it is also recommended that people with damaged respiratory muscles strengthen their breathing training to improve lung function, enhance respiratory muscle strength and endurance, and improve their overall health.

[0003] Effective breathing training usually requires the assistance of a breathing trainer. A common breathing trainer is the three-ball breathing trainer, which can be used for both exhalation and inhalation training. For exhalation training, the trainee holds the mouthpiece in their mouth and exhales deeply and evenly, causing the floats inside the three-ball breathing trainer to rise sequentially and hold them in the raised position for as long as possible, then releases the mouthpiece and inhales. For inhalation training, the trainer is inverted, and the trainee holds the mouthpiece in their mouth and inhales deeply and evenly, causing the floats inside the three-ball breathing trainer to rise sequentially and hold them in the raised position for as long as possible, then releases the mouthpiece and exhales. During training, the resistance level of the trainer can be adjusted according to the actual situation. By alternating between exhalation and inhalation training, the goal of strengthening respiratory muscles and improving lung capacity can be achieved. In addition, when using a three-ball breathing trainer, patients can combine it with some breathing techniques, such as pursed-lip breathing and diaphragmatic breathing, to enhance the effect of breathing training. Diaphragmatic breathing involves taking a deep breath through the nose and then slowly exhaling through the mouth; pursed-lip breathing involves inhaling through the nose and exhaling through the mouth, pursing the lips as if whistling. However, in clinical practice, patients often unconsciously inhale through their mouths during breathing training, resulting in ineffective training.

[0004] To address the aforementioned issues, the existing technology, specifically Chinese utility model patent application number CN202220745244.2, employs a one-way ventilation valve to seal the inner end of the mouthpiece, creating an air dead space. This forces patients to exhale through their mouths during pursed-lip breathing training, preventing them from inhaling. However, this method is unsuitable for mouth-inhalation training; if inhalation training is required, the one-way valve must be removed and reversed, making the operation cumbersome. Furthermore, both the one-way valve and mouthpiece are fixed in place in this patent, making disassembly and reassembly difficult and preventing the switching of breathing training modes. Utility Model Content

[0005] In view of the above, it is necessary to provide a breathing training mouthpiece that prevents aspiration. This mouthpiece can facilitate breathing training in various modes without requiring the removal and installation of a one-way valve or replacement of the mouthpiece to adapt to different breathing training modes, making it more convenient to use.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an anti-aspiration breathing training mouthpiece, comprising an installation section, an adjustment section, and a mouthpiece section connected in sequence; the installation section is detachably connected to the air delivery tube of the breathing trainer via a connector; the adjustment section is internally composed of two gas flow channels, both of which are connected to the installation section and the mouthpiece section, and each gas flow channel is equipped with a one-way valve, namely an exhalation one-way valve and an inhalation one-way valve; wherein, the gas flow path of the exhalation one-way valve is from the mouthpiece section to the installation section; the gas flow path of the inhalation one-way valve is from the installation section to the mouthpiece section; the adjustment section is equipped with an opening and closing component for controlling the opening and closing of the two gas flow channels, and the two gas flow channels are not closed simultaneously.

[0007] Furthermore, the regulating section includes regulating section A and regulating section B, each of the two gas flow channels being divided into two sections by regulating section A and regulating section B. The exhalation one-way valve is installed on the connecting section A, and the inhalation one-way valve is installed on the connecting section B. Regulating section A and regulating section B are connected by a connecting cylinder. The opening and closing element is installed on the connecting cylinder and is rotatably connected to the cylinder wall. The opening and closing element is provided with a sealing plate, which is located inside the connecting cylinder and, under the rotational action of the opening and closing element relative to the connecting cylinder, directly faces and seals one of the gas flow channels or is offset from both gas flow channels.

[0008] Furthermore, a connecting groove is formed on the inner wall of the connecting cylinder, the connecting groove is formed around the circumference of the connecting cylinder, and its opening faces the inside of the connecting cylinder. The opening and closing member is an annular connecting member, and the sealing plate is provided on the inner side of its annular shape. The outer edge of the annular opening and closing member is installed in the connecting groove and is slidably connected to the connecting groove. The opening and closing member is rotatably connected to the connecting cylinder by sliding its outer edge in the connecting groove. A notch is formed on the outer wall of the connecting cylinder, the notch is connected to the bottom of the connecting groove, the notch is sealed by the opening and closing member in the connecting groove, and the operating block provided on the annular outer wall of the opening and closing member extends to the outside of the connecting cylinder through the notch.

[0009] Furthermore, under the rotation of the opening and closing member relative to the connecting cylinder, the operating block only abuts against one side wall of the notch at a time. When the operating block abuts against the side wall of the notch, the gas flow channel where the suction one-way valve is located is completely closed or completely opened.

[0010] Furthermore, the opening and closing element is detachably connected to the side wall of the notch via a magnetic attachment.

[0011] Furthermore, the connector includes clamping blocks and a fixing sleeve. At least two clamping blocks are provided, all of which are arranged around the center line of the mounting section and spaced apart at one end of the mounting section, the end being the end away from the bite piece. The thickness of each clamping block gradually decreases from the end it connects to the mounting section to the other end. The fixing sleeve has a threaded section and a locking section connected in sequence inside. The fixing sleeve is threadedly connected to the mounting section through the threaded section. The locking section is a tapered horn shape, with the larger end of the horn opening connected to the threaded section. When the threaded section is threadedly connected to the mounting section, the locking section compresses the clamping blocks towards the center of the air delivery pipe to clamp and fix the air delivery pipe.

[0012] Furthermore, the adjusting section is detachably connected to the mouthpiece section, and a filter membrane is detachably installed between the mouthpiece section and the adjusting section.

[0013] Furthermore, the ends of the adjustment section and the mouthpiece section are both tubular structures, and they are connected by threads, with the filter membrane sandwiched between the adjustment section and the mouthpiece section.

[0014] Furthermore, the mouthpiece section has a gourd-shaped shape, and its internal gas channel is funnel-shaped, with the larger funnel opening facing the adjustment section.

[0015] Furthermore, the bite section is made of soft silicone material.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention, through the design of an opening and closing mechanism, allows users to choose whether to close the air inlet of the one-way valve according to the training objective. For nasal-to-mouth breathing training, the opening and closing mechanism can be used to close the gas flow channel of the inhalation one-way valve. In this case, the trainee can exhale through their mouth while biting the mouthpiece, but cannot inhale through their mouth, thus preventing the trainee from habitually inhaling through their mouth during nasal-to-mouth training. For alternating exhalation and inhalation training, the opening and closing mechanism can be used to open the gas flow channels of both one-way valves. With the function of the opening and closing mechanism, this invention can meet the needs of various breathing training modes without requiring disassembly and reassembly of the one-way valves or replacement of the mouthpiece to adapt to different training modes, making it convenient to use.

[0035] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0036] Please see Figure 1-10In a preferred embodiment of this utility model, an anti-aspiration breathing training mouthpiece includes an installation section 1, an adjustment section 2, and a mouthpiece section 3 connected in sequence. Preferably, the adjustment section 2 is detachably connected to the mouthpiece section 3, facilitating disassembly for cleaning and disinfection of the interior. Additionally, a filter membrane 31 is detachably installed between the mouthpiece section 3 and the adjustment section 2, preventing saliva and phlegm from entering the breathing trainer during training. In this embodiment, the filter membrane is preferably installed on the mouthpiece section, and both the filter membrane and the mouthpiece section can be replaced simultaneously. The detachable connection of the adjustment section 2 to the mouthpiece section 3 also facilitates the installation of the filter membrane 31. Specifically, the ends of both the adjustment section 2 and the mouthpiece section 3 are tubular structures connected by threads, with the filter membrane 31 clamped between the adjustment section 2 and the mouthpiece section 3. Furthermore, the mouthpiece section 3 is gourd-shaped, making it easy for users to place it in their mouths and seal it tightly. The internal gas passage of the mouthpiece section 3 is funnel-shaped, with the larger end of the funnel opening facing the adjustment section 2, facilitating direct airflow and outflow. Moreover, the mouthpiece section 3 is made of soft silicone, minimizing irritation to the oral cavity and providing a comfortable experience.

[0037] Furthermore, the installation section 1 is detachably connected to the air delivery tube 4 of the breathing trainer via the connector 11, facilitating the removal, cleaning, disinfection, and replacement of this utility model. Specifically, in this embodiment, the connector 11 includes a clamping block 111 and a fixing sleeve 112. At least two clamping blocks 111 are provided, all of which are arranged around the center line of the installation section and spaced apart at one end of the installation section 1, the end being the end furthest from the mouthpiece. The thickness of each clamping block 111 gradually decreases from one end connected to the installation section 1 to the other. The fixing sleeve 112 has a threaded section 1121 and a locking section 1122 connected sequentially inside. The mounting section 1 is threadedly connected to the threaded section 1121 via the threaded section 1121. The locking section 1122 is a tapered horn shape, with the larger end of the horn opening connected to the threaded section 1121. When the threaded section 1121 is threadedly connected to the mounting section 1, the locking section 1122 compresses the clamping block 111 to contract toward the center of the air delivery tube to clamp and fix the air delivery tube. The mounting section 1 is stably connected to the air delivery tube 4 of the breathing trainer by the locking section 1122 of the fixing sleeve 112 driving the clamping block 111 to clamp and fix the air delivery tube.

[0038] Furthermore, the regulating section 2 is composed of two gas flow channels, both of which are connected to the mounting section 1 and the mouthpiece section 3. Each gas flow channel is equipped with a one-way valve, namely an exhalation one-way valve 23 and an inhalation one-way valve 24. The gas flow path of the exhalation one-way valve 23 is from the mouthpiece section 3 to the mounting section 1; the gas flow path of the inhalation one-way valve 24 is from the mounting section 1 to the mouthpiece section 3. The regulating section 2 is equipped with an opening and closing element 26 for controlling the opening and closing of the two gas flow channels, and the two gas flow channels are not closed at the same time. Users can choose whether to close one of the gas flow channels according to the training purpose. For example, when training requires abdominal breathing or pursed-lip breathing, which requires inhaling through the nose and exhaling through the mouth, the user can choose to use the opening and closing part 26 to close the gas flow channel of the inhalation one-way valve 24, while the gas flow channel of the exhalation one-way valve 23 is open. At this time, the trainee bites the mouthpiece 3 to exhale. Since the gas flow channel of the inhalation one-way valve 24 is closed and the gas flow channel of the exhalation one-way valve 23 is open, the trainee cannot inhale through the mouth but can exhale through the mouth. This can prevent the trainee from habitually using the mouth to inhale when training nasal inhalation and oral exhalation. When alternating exhalation and inhalation training is required, the control opening and closing element 26 can be selected to open the gas flow channels of both one-way valves. During exhalation training, the air exhaled by the trainee from the mouthpiece section 3 can enter the breathing trainer through the gas flow channel of the exhalation one-way valve 23. During inhalation training, the trainee inhales through the mouthpiece section 3, causing the air to flow from the breathing trainer through the gas flow channel of the inhalation one-way valve 24 to the mouthpiece section 3 and then into the trainee's mouth or abdomen. With the action of the opening and closing element 26, this invention can meet the needs of multiple modes of breathing training without the need to disassemble and reassemble the one-way valves or replace the mouthpiece to adapt to different training modes, making it more convenient to use.

[0039] Preferably, the regulating section 2 includes regulating section A 21 and regulating section B 22. Both gas flow channels are divided into two sections by regulating section A 21 and regulating section B 22. The exhalation one-way valve 23 is disposed on the connecting section A 21, and the inhalation one-way valve 24 is disposed on the connecting section B 22. The regulating section A 21 and regulating section B 22 are connected by a connecting cylinder 25. There are various ways to connect the regulating section A 21 and regulating section B 22 to the connecting cylinder 25. They can be directly connected by integral molding, or by detachable connection such as threads or buckles, or by glue. There are various connection methods, and those skilled in the art can choose according to the actual situation.

[0040] Furthermore, the opening / closing member 26 is mounted on the connecting cylinder 25 and rotatably connected to the cylinder wall of the connecting cylinder 25. Preferably, in this embodiment, the opening / closing member 26 is rotatably connected to the connecting cylinder 25 in the following manner: a connecting groove 251 is provided on the inner wall of the connecting cylinder 25, the connecting groove 251 is opened around the circumference of the connecting cylinder 25, and its opening faces the inside of the connecting cylinder 25. The opening / closing member 26 is an annular connecting member, and the annular outer edge of the opening / closing member 26 is installed in the connecting groove 251 and slidably connected to the connecting groove 251. The opening / closing member 26 slides within the connecting groove 251 by means of its outer edge. The connecting cylinder 25 is rotatably connected to the connecting cylinder 25. A notch 252 is provided on the outer wall of the connecting cylinder 25, and the notch 252 communicates with the bottom of the connecting groove 251. The notch 252 is sealed by the opening and closing member 26 in the connecting groove 251, that is, the notch 252 is not connected to the inside of the connecting cylinder 25. The operating block 261 provided on the annular outer wall of the opening and closing member 26 extends to the outside of the connecting cylinder 25 through the notch 252. The user can adjust the opening and closing member 26 by operating the operating block 261 located on the outside of the connecting cylinder 25.

[0041] Specifically, the opening and closing element 26 opens and closes the gas flow passage of the one-way valve through the following structure: a sealing plate 262 is provided on the opening and closing element 26. The sealing plate 262 is located on the inner annular side of the opening and closing element 26 and inside the connecting cylinder 25. Under the rotational connection between the opening and closing element 26 and the connecting cylinder 25, it faces and covers one of the gas flow passages or is offset from both gas flow passages. When the sealing plate 262 faces a gas flow passage, the gas flow passage is closed. When it is offset from the gas flow passage, the gas flow passage is opened.

[0042] Since exhalation training in actual practice involves exhaling through the mouth, there is no need to close the gas flow channel of the exhalation one-way valve 23. Instead, the gas flow channel of the inhalation one-way valve 24 needs to be controlled for opening and closing. Therefore, in this embodiment, the notch 252 on the connecting pipe is used to limit the movement of the operating block 261, so that the opening / closing element 26 only controls the opening and closing of the gas flow channel of the inhalation one-way valve 24. Specifically, the operating block 261 only abuts against one side wall of the notch 252 at a time under the rotation of the opening / closing element 26 relative to the connecting cylinder 25. When the operating block 261 abuts against the side wall of the notch 252, the sealing plate 262 is directly opposite the gas flow channel of the inhalation one-way valve 24, or offset from it, thus completely closing or opening the gas flow channel of the inhalation one-way valve 24. The opening and closing status of the gas flow channel of the inhalation one-way valve 24 can be determined by the position of the operating block 261. More preferably, the opening and closing member 26 is detachably connected to the side wall of the notch 252 via a magnetic attraction member. Under the action of magnetic attraction, the operating block 261 can be fixedly abutted against a certain side wall of the notch 252, thereby ensuring that the gas flow channel of the inhalation one-way valve 24 is in a stable open or closed state, avoiding automatic opening and closing under non-human circumstances, which is conducive to the smooth progress of breathing training.

[0043] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
