Description

Technical Field

[0001] The utility model relates to the technical field of mouthpieces, in particular to an adjustable mouthpiece for auxiliary airway clearing technology. Background Art

[0002] ACBT is a technology that has a good effect on patients among airway clearance techniques. During the ACBT exercise process, there is a step called exhaling, but many patients often cannot do it well and need to use a mouthpiece for assistance, similar to the mouthpiece in a COPD pursed lip breathing exercise device with authorization announcement number CN212439922U and authorization announcement date of February 2, 2021.

[0003] The above-mentioned prior art still has the following problems during use. The size of the existing mouthpiece is not adjustable and is an integrated structure, similar to the mouthpiece in the above-mentioned prior art. When assisting exhalation, the larger the caliber of the mouthpiece is within a certain limit, the better. For patients of different groups, the mouthpiece with a non-adjustable caliber may be smaller for some patients and have a poor assisting effect, while it may be larger for some child patients.

[0004] Therefore, we propose an adjustable assisted airway clearance technique with a mouthpiece to solve the above problems. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides an adjustable mouthpiece for auxiliary airway clearing technology, which solves the problem that the size of the existing mouthpiece cannot be adjusted and the applicability is low.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable mouthpiece for auxiliary airway clearing technology, including a mouthpiece body, the mouthpiece body is composed of a plurality of arc-shaped plates, one side of the arc-shaped plate is fixedly connected to a limiting slide bar, the other side of the arc-shaped plate is provided with a limiting slide groove slidably connected to the limiting slide bar, and a limiting mechanism is arranged at one end of the arc-shaped plate.

[0007] Preferably, the limiting mechanism comprises an arc-shaped slide groove penetrating through one end of the arc-shaped plate, a plurality of arc-shaped slide grooves are connected, and an arc-shaped slider is slidably connected in the arc-shaped slide groove.

[0008] Preferably, anti-slip grooves are provided on the outer side of the arc-shaped sliding block.

[0009] Preferably, a push block is fixedly connected to the outer side of the arc-shaped sliding block.

[0010] Preferably, the depth of the limiting sliding groove is smaller than the length of the arc-shaped plate.

[0011] Preferably, the length of the limiting sliding strip is consistent with the depth of the limiting sliding groove.

[0012] Preferably, the limiting slide bar and the limiting slide groove are both T-shaped.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] This adjustable auxiliary airway clearing technology mouthpiece splits the mouthpiece body into multiple arc plates. When in use, multiple arc plates can be spliced ​​according to the required size to form a cylindrical state, thereby improving the applicability of the mouthpiece. When splicing, the limiting slide bar on one side of the arc plate is slid into the limiting slide groove on the other side of the arc plate. After use, it can be disinfected and reused. When some parts are damaged, only the damaged arc plate needs to be replaced to avoid the waste of replacing the entire mouthpiece. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 6, an adjustable mouthpiece for auxiliary airway clearing technology, including a mouthpiece body, the above structure is similar to the structure and function in the Chinese patent document with authorization announcement number CN212439922U, the mouthpiece body is composed of a plurality of arc plates 1, by splitting the mouthpiece body into a plurality of arc plates 1, when in use, a plurality of arc plates 1 can be spliced ​​according to the required size, and they can be spliced ​​into a cylindrical state, thereby improving the applicability of the mouthpiece, one side of the arc plate 1 is fixedly connected to a limiting slide bar 2, and the other side of the arc plate 1 is provided with a limiting slide groove 3 slidably connected to the limiting slide bar 2, when splicing, the limiting slide bar 2 on one side of the arc plate 1 is slid into the limiting slide groove 3 on one side of the other arc plate 1, after use, it can be disinfected and reused, and when some parts are damaged, only the damaged arc plate 1 needs to be replaced, avoiding the waste caused by replacing the entire mouthpiece, and a limiting mechanism is provided at one end of the arc plate 1.

[0024] When in use, the mouthpiece body is spliced ​​according to the patient. When splicing, the limiting slide 2 on one side of the arc plate 1 is slid into the limiting slide groove 3 on the other side of the arc plate 1, and multiple arc plates 1 are spliced ​​into a cylindrical state. Then, through the cooperation of the limiting mechanism, the limiting slide 2 can be prevented from being separated from the limiting slide groove 3 during use.

[0025] like Figure 4 and Figure 6 As shown, further, the limiting mechanism includes an arc-shaped slide groove that passes through one end of the arc-shaped plate 1, and multiple arc-shaped slide grooves are connected. An arc-shaped slider 4 is slidably connected in the arc-shaped slide groove. During the above-mentioned use, after multiple arc-shaped plates 1 are spliced ​​into a cylindrical shape, the arc-shaped slider 4 is pushed to move a part of the position of the arc-shaped slider 4 to another arc-shaped slide groove, and so on, to limit the multiple arc-shaped plates 1 and prevent the limiting slide bar 2 from detaching from the limiting slide groove 3.

[0026] like Figure 4 and Figure 6 As shown, further, anti-skid grooves are provided on the outer side of the arc-shaped sliding block 4, and the anti-skid grooves facilitate pushing the arc-shaped sliding block 4 to slide in the arc-shaped sliding groove.

[0027] like Figure 6 As shown, further, a push block 5 is fixedly connected to the outer side of the arc-shaped sliding block 4, and the push block 5 facilitates the arc-shaped sliding block 4 to slide in the arc-shaped sliding groove.

[0028] like Figure 2 As shown, further, the depth of the limiting slide groove 3 is less than the length of the arc plate 1, and the length of the limiting slide bar 2 is consistent with the depth of the limiting slide groove 3. When splicing, the limiting slide bar 2 is slid into the limiting slide groove 3 until it stops sliding. At this time, multiple arc slide grooves are connected.

[0029] like Figure 3As shown, further, the limiting slide bar 2 and the limiting slide groove 3 are both T-shaped to prevent the limiting slide bar 2 from escaping from the limiting slide groove 3 when the limiting slide bar 2 slides in the limiting slide groove 3.

[0030] It should be noted that: since the mouthpiece is inserted into people's mouths, a hard round tube is not used, and a soft round tube is generally used. After increasing or decreasing the number of arc plates 1, a cylindrical shape can be formed through deformation.
