[0020] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention. Example

[0021] An oxygen mask described in this embodiment, such as Figure 1 As shown, the mask body 1 includes a mask body 1, which is an existing known product and is mainly composed of a mask shell, a nose clip, a strap 2, an oxygen conduit and a connector. The mask shell is used to cover the nose and mouth. The strap is used to fix the mask shell to the patient's head. The nose clip is used to adjust the fit between the mask and the nose to ensure oxygen circulation and reduce leakage. The oxygen conduit is used to connect the mask and the oxygen source pipeline to transport oxygen to the mask. The connector is used to connect with the interface of the oxygen cylinder or other oxygen supply equipment. When in use, the mask shell is placed on the patient's face, the straps are two left and right, and then the mask shell is tied to the patient's face with two straps, and finally the oxygen supply to the patient can be completed through the oxygen conduit and the connector.

[0022] like Figure 1 and 2As shown, the strap 2 on the mask body 1 is provided with a connecting strip 4 along its length direction, and the connecting strip 4 is provided with a groove for placing the strap 2 along its length direction, as shown in FIG. Figure 1 In the middle position, the groove is in a state of being connected to the left and right, so the strap 2 can be smoothly placed in the groove; the groove width can be designed according to the width of the strap 2, so that the strap 2 is just placed in the groove without too much movement gap, and the strap 2 can be initially limited by placing it in the groove;

[0023] The connecting strip 4 is made of soft material. When the strap 2 drives the mask body 1 to be tied to the patient's face, the strap 2 will bend. At this time, through the design of soft material, the connecting strip 4 is easy to bend or move with the strap 2; at the same time, it can also avoid causing discomfort to the patient;

[0024] like Figure 1 and Figure 2 As shown, a limiting strip 3 is provided on the connecting strip 4, and the limiting strip 3 is made of a soft material, and the limiting strip 3 is fixed in the notch of the groove; this section of the scheme as a whole constitutes a limiting component for limiting the strap 2 from moving out of the notch of the groove; the limiting strip 3 is made of a soft material, and when the strap 2 drives the connecting strip 4 to move, the limiting strip 3 is also convenient to bend or move with the connecting strip 4 and the strap 2; after the limiting strip 3 is fixed in the notch of the groove, the notch of the groove is not completely blocked by the limiting strip 3, and a gap is left between the limiting strip 3 and the notch of the groove, and the material of the strap 2 is also relatively soft. At this time, through the gap and the softness of the strap 2, the strap 2 can be put into the groove through the gap, and when the strap 2 is put in, the limiting strip 3 can further limit the position of the strap 2 in the groove, and the strap 2 can be restricted in the groove without an external force moving in the direction of the notch of the groove;

[0025] In a specific implementation process, the limiting strip 3 in the limiting assembly can be replaced with an adhesive tape, and the adhesive tape can be adhered to the notch of the groove to prevent the binding strap 2 from moving out of the groove;

[0026] like Figure 1 and Figure 2 As shown, there are two limiting strips 3, and they are symmetrically installed at the notch of the groove along the length direction of the groove, and the distance between the two limiting strips 3 is smaller than the width of the strap 2; because the strap 2 is made of relatively soft material, the strap 2 can be squeezed into the groove through the distance between the two limiting strips 3; when the strap 2 enters the groove, because the distance between the two limiting strips 3 is smaller than the width of the strap 2, the strap 2 can be stably placed in the groove without the action of external force; thus, through the design of the two limiting strips 3, the strap 2 can be more stably limited in the groove;

[0027] like Figure 1 , Figure 2and Figure 3 As shown, a sponge pad 5 is provided on the connecting strip 4, and the sponge pad 5 is fixed on a side wall of the connecting strip 4 away from the groove; this section of the scheme as a whole constitutes a buffer component for reducing the pressure exerted by the connecting strip 4 on the patient's skin; Figure 2 In the orientation, the left side of the connecting strip 4 is one side of the groove, and the side wall away from the groove is the right side wall of the connecting strip 4, so the sponge pad 5 is fixed on the right side wall of the connecting strip 4, corresponding to Figure 1 In the middle position, the sponge pad 5 is located at the rear side of the strap 2; when in use, Figure 3 The two straps 2 are tied tightly behind the patient's head in the middle position, so as to fix the mask body 1 on the patient's face; when the mask body 1 is tied tightly, the sponge pad 5 contacts the patient's skin, the sponge pad 5 is fixed on the connecting strip 4, and the strap 2 is limited in the groove on the connecting strip 4 by the limiting strip 3. During the limiting process, because the strap 2 applies force to one side of the sponge pad 5, and the notch of the groove is in the opposite direction to the sponge pad 5, the strap 2 will not move out from one side of the notch of the groove, so that the strap 2 can be stably limited in the groove by the limiting strip 3; when the strap 2 is limited, the part originally in contact with the patient's skin is replaced by the sponge pad 5, so as to avoid The strap 2 is prevented from directly contacting the patient's skin, and the sponge pad 5 is made of a relatively soft material, so that the patient can reduce the pressure caused by the strap 2 when using the strap 2, improve the comfort, and avoid the occurrence of pressure sores; secondly, when used by children, if the strap 2 causes discomfort during the binding process, the child is likely to be uncooperative. Through the design of the sponge pad 5, the child can wear the mask body 1 more cooperatively, so this design has certain practicality; the limit strip 3, the connecting strip 4 and the sponge pad 5 in this design are not only applicable to the strap 2 on the oxygen mask, but also to other masks, such as the strap 2 on the atomizer mask;

[0028] In the specific implementation process, the sponge pad 5 in the buffer component can also be replaced with preventive dressings such as hydrocolloid, foam pad or transparent film, so as to reduce skin damage and pressure.

[0029] More preferably, the side of the connecting strip 4 close to the skin is configured as a curved surface structure that fits the cheek skin, such as Figure 2 In the middle position, the right side wall of the connecting strip 4 is a side of a curved surface structure, and the sponge pad 5 is designed as a curved surface structure with the same curvature according to the connecting strip 4. Therefore, when the sponge pad 5 contacts the patient's skin, the contact surface can be increased, so that the sponge pad 5 fits more stably on the face, thereby improving the stability of the sponge pad 5 when in contact with the face;

[0030] Further preferably, the limiting strip 3, connecting strip 4 and sponge pad 5 in the present design can be designed to have different widths, because people's faces vary in size. By designing them to have different sizes, when used for patients with smaller cheeks, narrower limiting strips 3, connecting strips 4 and sponge pad 5 can be used, and when used for patients with fatter cheeks, wider limiting strips 3, connecting strips 4 and sponge pad 5 can be used. The design of multiple sizes makes it easier for patients with different cheek sizes to use, thereby improving practicality.

[0031] The connecting strip 4 is made of silicone material, and the limiting strip 3 is made of silicone material; silicone has many advantages, such as wear resistance, soft material, lightness, no burden on the local area, low price and high cost performance; therefore, through the design of silicone material, the limiting strip 3 and the connecting strip 4 not only have a long service life during use, but also can save production costs; at the same time, because the limiting strip 3, the connecting strip 4 and the sponge pad 5 can be removed from the strap 2, the limiting strip 3 and the connecting strip 4 can be reused after cleaning and disinfection, which reduces the use cost;

[0032] The length of the connecting strip 4 is 18cm-22cm, the length of the limiting strip 3 is 18cm-22cm, and the length of the sponge pad 5 is 18cm-22cm; in actual use, the lengths of the connecting strip 4, the limiting strip 3 and the sponge pad 5 can be selected to be 18cm, 19cm, 20cm, 21cm, 22cm or between 18cm-22cm, because the distance from the tip of the nose to the back of the ear is usually 15 to 20 centimeters. When the limiting strip 3, the connecting strip 4 and the sponge pad 5 are used, their positions are adjusted so that one end of them is close to the mask body 1. Therefore, the lengths of the limiting strip 3, the connecting strip 4 and the sponge pad 5 are approximately taken from the position of the patient's nose as the starting end, so ... preferably selected to be 18cm, 19cm, 20cm, 21cm, 22cm or between 18cm-22cm. When the limit strip 3, the connecting strip 4 and the sponge pad 5 are moved in the direction above the patient's ear, the skin from the nose to the back of the ear can be fully covered; if the length of the limit strip 3, the connecting strip 4 and the sponge pad 5 is less than 18 cm, it is possible that the length is too short, and the sponge pad 5 cannot cover the skin from the patient's nose to the ear, and the buffering efficiency is reduced; the limit strip 3 and the connecting strip 4 cannot stably limit the strap 2 of this distance; if the length of the limit strip 3, the connecting strip 4 and the sponge pad 5 is greater than 22 cm, it is possible to waste resources; therefore, through the design within this range, not only can the patient's facial skin be fully protected, but also the production cost can be saved;

[0033] During the specific use process: first, put the strap 2 on the mask body 1 into the groove on the connecting strip 4. During the placement process, because the materials of the strap 2 and the limiting strip 3 are soft, the strap 2 can be smoothly placed in the groove by squeezing the limiting strip 3. When the placement is completed, under the action of the limiting strip 3, the strap 2 can be limited in the groove; then, the strap 2 is tied to the back of the patient's head, thereby driving the mask body 1 to be tied tightly to the patient's face. After tightening, the sponge pad 5 fixed on the connecting strip 4 is the side in contact with the patient's skin, thereby avoiding the strap 2 from contacting the patient's skin; because the material of the sponge pad 5 is soft, the problem of bringing a sense of oppression to the patient's skin is avoided as much as possible during the long-term wearing of the mask body 1.
