Description

Technical Field

[0001] This utility model belongs to the field of nursing equipment technology, and in particular relates to a protective earmuff. Background Technology

[0002] After ear surgery, such as otitis media drainage or ear deformity surgery, a rigid earmuff can be used to protect the ear from accidental touching or pressure on the wound while sleeping or in daily life.

[0003] Common earmuffs are typically in the form of headsets, covering both ears simultaneously. However, headset-style earmuffs are prone to falling off, and the fact that they cover both ears at once adds inconvenience for patients who have only had surgery on one ear. Furthermore, conventional transparent bowl-shaped earmuffs are unsuitable for patients whose ears are frequently wrapped with cotton balls or gauze after surgery, resulting in varying sizes of the covered area. Thirdly, for drainage procedures, where drainage tubes are inserted, existing earmuffs lack corresponding notches to avoid these tubes, causing the edges of the earmuffs to press against the drainage tubes, making them very inconvenient to use. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a protective earmuff, which aims to solve the above technical problems.

[0005] The present invention adopts the following technical solution:

[0006] A protective earmuff includes an upper earmuff and a lower earmuff, which are joined together and both bulge outwards. The edges of the two earmuffs are formed by an integral skirt, the bottom surface of which is covered with flexible cotton. The upper and lower earmuffs are connected by several guide components and several adjustment and fixing components. Both earmuffs have ear loops. The adjustment and fixing components include a first connecting tube fixed to the upper earmuff and a second connecting tube fixed to the lower earmuff. A steel shaft is fixed to the first connecting tube and passes through the second connecting tube. The second connecting tube has a buckle. The steel shaft has several positioning holes, and the bottom surface of the buckle has a locking block for embedding into the positioning holes.

[0007] Furthermore, the guide assembly includes a third connecting tube fixed on the upper cover and a fourth connecting tube fixed on the lower cover. A guide shaft is fixed on the third connecting tube, and the guide shaft passes through the corresponding fourth connecting tube.

[0008] Furthermore, one of the two enclosures has an opening at its bottom edge.

[0009] Furthermore, both covers have air vents.

[0010] Furthermore, the hanging ears are disposed on the skirt panel, and there are two adjustment and fixing components.

[0011] The beneficial effects of this utility model are as follows: The earmuff of this structure is a split type, connected in the middle by a guide component and an adjustment and fixing component. By adjusting the distance between the two covers, the size of the internal space of the earmuff can be adjusted, making it more versatile. In addition, this earmuff has two ways of use: the earmuff can be fixed to the ear by tying a connecting strap on the ear hook, or the earmuff can be directly covered to the ear and then fixed to the ear with gauze strips wrapped around the surface. In the preferred structure, the earmuff is also provided with a clearance opening for the drainage tube to pass through, which can be adapted for drainage surgery and further expands the application scenarios.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0017] like Figure 1-3 As shown, the protective earmuffs provided in this embodiment include an upper cover 1 and a lower cover 2. The upper and lower covers are spliced ​​together and both bulge outwards. The edges of the two covers are formed by an integral skirt 3. The bottom surface of the skirt 3 has flexible cotton 4. The upper and lower covers are connected as a whole by several guide components 5 and several adjustment and fixing components 6. In the figure, there are three guide components and two adjustment and fixing components. Both covers have ear loops 7. The adjustment and fixing components 6 include a first connecting tube 61 fixed to the upper cover 1 and a second connecting tube 62 fixed to the lower cover 2. A steel shaft 63 is fixed on the first connecting tube 61 and passes through the second connecting tube 62. The second connecting tube 62 has a buckle 64. The steel shaft 63 has several positioning holes 65. The bottom surface of the buckle 64 forms a locking block 66 for embedding into the positioning hole. The ear loops 7 are disposed on the skirt 3.

[0018] In this structure, the guide component 5 serves a guiding function, and the adjusting and fixing component 6 serves a fixing and locking function after length adjustment. As a specific structure of the guide component 5, it includes a third connecting pipe 51 fixed to the upper cover 1 and a fourth connecting pipe 52 fixed to the lower cover 5. A guide shaft 53 is fixed to the third connecting pipe 51, and the guide shaft 53 passes through the corresponding fourth connecting pipe 52. Therefore, when adjusting the distance between the upper and lower covers, the movement is guided by the guide shaft, ensuring stability.

[0019] The adjustment assembly includes a steel shaft and a latch, such as... Figure 3 As shown, there are three positioning holes on the steel shaft. The latches are located in one of these holes and cannot move relative to each other, allowing for three-level distance adjustment. When adjustment is needed, simultaneously engage two latches and move the lower cover. After adjustment, the latches automatically retract to lock the position. Therefore, this embodiment's structure allows for adjustment of the internal space of the earcups by adjusting the distance between the two covers, making it more versatile. Furthermore, this earcup can be used in two ways. First, the earcup can be secured to the ears by attaching connecting straps to the ear hooks, with one strap going up over the head and the other around the chin, then locking it. Alternatively, the earcup can be directly placed over the ears and secured with gauze straps, which is also a viable method.

[0020] These earmuffs are made of hard, transparent plastic, allowing you to see inside. Both earmuffs have vents (9) for ventilation.

[0021] Finally, regarding the drainage technique, in this embodiment, one of the two covers has a relief opening 8 at its bottom edge. The illustration shows the relief opening at the bottom edge of the upper cover. The drainage tube is led out from the relief opening, and the earmuff will not squeeze the drainage tube. This protective earmuff is particularly suitable for this scenario and is superior to existing earmuff designs.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
