Detailed Description

The following detailed description of embodiments of the utility model refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the utility model, are given by way of illustration and explanation only, not limitation.

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

In embodiments of the utility model, where the context requires otherwise, the use of directional terms such as "upper, lower, top and bottom" is generally intended in the orientation shown in the drawings or the positional relationship of the various components in a vertical, vertical or gravitational orientation.

The utility model will be described in detail hereinafter with reference to the drawings and in connection with exemplary embodiments.

In an exemplary embodiment of the present invention, a protective mask is provided that includes a flexible strip 10, a wearing unit 20, and a nasal shield 30. Wherein the wearing unit 20 extends outwardly from the end of the flexible strip 10 and comprises an elastic ear-hanging strap 21. Nasal shield 30 includes horizontal shield 31 and curved shield 32, horizontal shield 31 extending horizontally outward from the circumferential side of flexible strip 10, and curved shield 32 extending upward from horizontal shield 31.

After the patient wears the protective mask, when a dentist works through a high-speed tooth grinding mobile phone, the situation of choking cough caused by water mist splashing to the nasal cavity is avoided, and the protective mask is especially important for the patient suffering from nasal cavity diseases or respiratory diseases. Specifically, the flexible strip 10 has a certain flexibility, that is, can generate a certain deformation under the action of external force, and after the protective mask is worn, the flexible strip 10 is located between the nostrils and the upper lip. The patient wears the unit 20 and the flexible strip 10 is secured in place by placing the elastic ear straps 21 over the ears. After the flexible strip 10 is fixed, the horizontal blocking screen 31 is located below the nostrils, and the curved blocking screen 32 extending upwards blocks the nostrils, so that water mist is prevented from entering the nasal cavity of a patient, discomfort is avoided, and the patient experience in diagnosis is improved.

Further, the flexible strip 10 comprises a flexible base layer 11, a skin-friendly layer 12 and a protective layer 13. Wherein, the skin-friendly layer 12 is arranged on the inner side surface of the flexible base layer 11, and the protective layer 13 is arranged on the outer side surface of the flexible base layer 11.

Specifically, the flexible strip 10 is formed by compounding three layers of materials made of different materials, so that the flexible strip 10 has good performance. The flexible base layer 11 may be made of a bendable plastic sheet or a metal sheet, and the like, so as to ensure good bending fatigue resistance. The skin-friendly layer 12 is one side attached to the skin of a patient, and the skin-friendly layer 12 can be made of sponge, silica gel or foam, so that the softness and elasticity of the skin-friendly layer are guaranteed, and the skin is not irritated. The protective layer 13 is located on the side relatively far away from the skin, and may be rubber coated on the outer side surface of the flexible base layer 11, and has a certain protective function for the flexible base layer 11 and the skin-friendly layer 12 located on the inner side.

After the mask is worn, the flexible strip 10 is located below the nostrils, and in order to form a larger gas flow space between the nostrils and the flexible strip 10, in the embodiment of the utility model, a concave breathing groove 14 is arranged in the middle of the flexible strip 10. When the patient wears the protective mask, the breathing groove 14 can be aligned to the position below the nostrils, so that the patient can breathe conveniently. It can be understood that if the width of the flexible strip 10 is too narrow, it is easy to press the lips of the patient, but if the width of the flexible strip 10 is too wide, it may block the oral cavity, block the view of the operation area of the dentist, and affect the operation of the oral cavity, therefore, in this embodiment, the width of the flexible strip 10 is preferably 10 mm-20 mm.

In an embodiment of the utility model, the wearing unit 20 further comprises an elastic connecting band 22, the elastic connecting band 22 being connected between the end of the flexible strip 10 and the elastic ear-hanging band 21.

It should be noted that, in the present embodiment, the elastic ear hanging belt 21 is made by winding a thin elastic rope into a ring, and if the elastic ear hanging belt 21 is worn directly, the elastic ear hanging belt 21 will cause a large pressure on the face of the patient, which causes discomfort, so the elastic connecting belt 22 is additionally arranged between the flexible strip 10 and the elastic ear hanging belt 21, and after the protective mask is worn, the elastic connecting belt 22 is attached to the face to reduce the pressure. It will be appreciated that the width of elastic connecting band 22 is suitably selected, and preferably, the width of elastic connecting band 22 is 20mm to 30 mm.

In the embodiment of the present invention, the angle between the curved screen 32 and the horizontal screen 31 is an obtuse angle.

Specifically, in the present embodiment, the curved screen 32 extends obliquely upward relative to the horizontal screen 31, and an included angle between the curved screen 32 and the horizontal screen 31 is an obtuse angle. So set up, wear this protective mask the back, along vertical direction, the curved surface keeps off the space between screen 32 and the face and is bigger and bigger, avoids taking place to interfere with the face.

Further, the radius of the curved barrier 32 increases in the bottom-up direction. In other words, the curved screen 32 presents a shape with a narrow lower part and a wide upper part, so that the triangular area formed by the glasses and the nose can be well shielded, the bad influence of the splashed water mist on the sense organs of the face can be avoided, meanwhile, most of the face area can be shielded, and particularly for female patients, the face makeup can be protected.

Of course, in order to make the curved screen 32 reach the eye height, in the present embodiment, the height of the curved screen 32 is preferably between 70mm and 100 mm.

In an embodiment of the present invention, the nasal shield 30 is a clear resin shield. In other words, the nose screen 30 is made of a transparent resin material, so that the patient can conveniently act on the external environment by wearing the protective mask, and for example, the patient can conveniently look up a water cup for mouth.

To sum up, after the patient wears foretell protective mask, can not form the art district field of vision to the dentist and shelter from, the water smoke that produces when the dentist uses high-speed cell-phone of grinding one's teeth in a mouth is sheltered from outside by this protective mask, avoids appearing bucking the risk of coughing because of water smoke entering nasal cavity produces, because the shroud scope of this protective mask covers eyes, consequently can further avoid the uncomfortable sense that causes because of water smoke splash to the eye, this protective mask adopts skin-friendly material with skin contact part, improves patient's experience of seeking medical advice.
