Description

Technical Field

[0001] The utility model relates to the technical field of breathing trainers, and particularly relates to a mouthpiece for a breathing trainer. Background Technique

[0002] Respiratory training is a necessary and very effective method for pulmonary rehabilitation training of patients with chronic obstructive airway diseases (COPD, including chronic obstructive pulmonary disease, bronchiectasis, pulmonary cystic fibrosis, bronchial asthma, obstructive pulmonary emphysema, etc.), spinal cord injury patients, and long-term bedridden patients. At the same time of respiratory training, effective airway clearance can also be achieved. Effective airway clearance can significantly improve the conditions of chronic mucus hypersecretion airway inflammation and acute pulmonary infection such as COPD, bronchiectasis, and pulmonary cystic fibrosis.

[0003] Efficient respiratory training depends on a suitable breathing trainer. The main part of the breathing trainer is developed based on the principle of increasing expiratory resistance, so patients need to bite the mouthpiece part of the breathing trainer well and exhale fully to achieve the training effect.

[0004] At present, during the use of the breathing trainer, there is a lack of a limiting and fixing structure for the dental arch, resulting in unstable occlusion of the mouthpiece. Therefore, it is necessary to propose a mouthpiece for a breathing trainer to solve the above-mentioned problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a mouthpiece for a breathing trainer, which has the characteristics of realizing the sealing of the connection between the connecting pipe and the extension pipe, and at the same time can limit the dental arch part of the user to achieve stable occlusion of the mouthpiece.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A mouthpiece for a breathing trainer, including a connecting pipe, a mouthpiece is installed on the right side of the connecting pipe, limiting grooves are opened on both the front and rear sides of the outer wall of the mouthpiece, and two bosses are fixedly connected to both the front and rear sides of the outer wall of the mouthpiece, respectively located on the left and right sides of the limiting groove; a plurality of grooves are opened on the four bosses on the opposite sides of each other in pairs.

[0007] The left side of the mouthpiece is communicated with an extension pipe that is threadedly connected to the connecting pipe, a retaining ring is fixedly connected to the inside of the connecting pipe close to the extension pipe, and a retaining groove that abuts against the extension pipe is opened on the right side of the retaining ring.

[0008] In order to make the mouthpiece stably occlude in the mouth, as a preferred mouthpiece for a breathing trainer of the utility model, limiting pieces are fixedly connected to both the upper and lower sides of the outer wall of the mouthpiece, and the edge of the limiting piece is in an arc structure.

[0009] To block dust, preferably as a mouthpiece for a respiratory trainer of the present utility model, a baffle is fixedly connected to the outer wall of the extension tube and abuts against the right side of the connecting tube.

[0010] To ensure the sealing between the extension tube and the connecting tube, preferably as a mouthpiece for a respiratory trainer of the present utility model, a sealing ring is installed between the outer wall of the extension tube and the inner wall of the connecting tube.

[0011] To ensure the normal flow of gas, preferably as a mouthpiece for a respiratory trainer of the present utility model, a through hole communicating with the extension tube is formed through the middle of the retaining groove.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The present utility model first threadedly connects the extension tube into the connecting tube, and positions the extension tube within the retaining groove. At the same time, the extension tube abuts against the retaining ring, thereby achieving the sealing between the connecting tube and the extension tube. Then, the mouthpiece is placed in the mouth, and the upper and lower teeth are respectively bitten within the limiting grooves. At the same time, the two groups of convex platforms are located on the inner and outer sides of the upper and lower dental arches, thereby limiting the dental arch part of the user and achieving the effect of stable biting of the mouthpiece.

[0018] Please refer to Figures 1 to 3 , a mouthpiece for a respiratory trainer, comprising a connecting tube 1. A mouthpiece 3 is installed on the right side of the connecting tube 1. Limiting grooves 301 are formed on both the front and rear sides of the outer wall of the mouthpiece 3. Two convex platforms 302 are fixedly connected to both the front and rear sides of the outer wall of the mouthpiece 3, respectively located on the left and right sides of the limiting groove 301. A plurality of grooves 303 are formed on the opposite sides of the four pairs of convex platforms 302.

[0019] The left side of the mouthpiece 3 is connected to an extension tube 305 that is threadedly connected to the connecting tube 1. Inside the connecting tube 1 near the extension tube 305, a retaining ring 2 is fixedly connected. On the right side of the retaining ring 2, a retaining groove 201 that abuts against the extension tube 305 is provided.

[0020] In this embodiment: The extension tube 305 is threadedly connected inside the connecting tube 1, and the extension tube 305 is located within the retaining groove 201. At the same time, the extension tube 305 abuts against the retaining ring 2, thereby achieving the sealing performance of the connection between the connecting tube 1 and the extension tube 305. Then, the mouthpiece 3 is placed in the mouth, and the upper and lower teeth respectively bite within the limiting grooves 301. At the same time, the two sets of bosses 302 are located on the inner and outer sides of the upper and lower dental arches, thereby achieving the limitation of the user's dental arch part and realizing the effect of stable biting of the mouthpiece 3.

[0021] As a technical optimization scheme of the present utility model, on both the upper and lower sides of the outer wall of the mouthpiece 3, limiting pieces 304 are fixedly connected. The edges of the limiting pieces 304 are in an arc structure.

[0022] In this embodiment: The mouthpiece 3 is held in the mouth, and the two limiting pieces 304 are respectively located outside the corners of the mouth, thereby enabling the mouthpiece 3 to be stably bitten in the mouth.

[0023] As a technical optimization scheme of the present utility model, a retaining piece 306 that abuts against the right side of the connecting tube 1 is fixedly connected to the outer wall of the extension tube 305.

[0024] In this embodiment: Through the retaining piece 306, the sealing performance between the connecting tube 1 and the extension tube 305 can be further ensured, preventing dust and the like from entering.

[0025] As a technical optimization scheme of the present utility model, a sealing ring 202 is installed between the outer wall of the extension tube 305 and the inner wall of the connecting tube 1.

[0026] In this embodiment: Through the sealing ring 202, the sealing performance of the connection between the extension tube 305 and the connecting tube 1 can be ensured.

[0027] As a technical optimization scheme of the present utility model, a through hole communicating with the extension tube 305 is penetratingly provided in the middle of the retaining groove 201.
