Description

Technical Field

[0001] The utility model relates to the technical field of breathing masks. Specifically, the utility model relates to a breathing mask with a double-hardness buffer pad, so as to increase the adaptability between the breathing mask and the human face and achieve a better sealing effect. Background Art

[0002] A breathing mask is the main device used to assist patients with dyspnea in positive pressure ventilation, and is also often used by doctors in clinical operations or treatments to assist patients in breathing or to enable patients to inhale drugs that need to be inhaled through breathing. It is a very important medical auxiliary device.

[0003] A breathing mask generally includes a swivel tube. One end of the swivel tube is connected to a gas supply device through a ventilation catheter, and the other end is connected to a mask bracket. The other end of the mask bracket is provided with a buffer pad for contacting the human face.

[0004] Due to the great differences in the shape and size of the human face, and the breathing mask cannot be personalized and matched according to the differences of the human face. Therefore, the existing breathing masks have the problem that the buffer pad does not fit well with the human face due to the large differences in the human face, resulting in gas flowing out through the gap between the mask and the human face during use, generating relatively large noise. This noise affects the patient's rest on the one hand, and may even affect the patient's mood and the treatment effect. Summary of the Utility Model

[0005] In view of the problem that the currently used breathing masks have poor sealing performance and generate relatively large noise, the embodiments of the present application provide a breathing mask with a double-hardness buffer pad.

The inside of the swivel tube first end and the swivel tube second end is communicated. The swivel tube first end is provided with a swivel tube installation part. The swivel tube installation part is rotatably connected to the swivel head assembly installation part on the mask bracket. The second end of the swivel tube is provided with a ventilation catheter installation part for connecting to a ventilation catheter;

[0008] Buffer pad assembly, including a buffer pad bracket, the first end of the buffer pad bracket is connected to the buffer pad assembly installation part of the mask bracket, and further includes a soft buffer pad made of a first hardness material in contact with the human face, and a buffer pad made of a second hardness material. The buffer pad made of the second hardness material connects the buffer pad bracket and the soft buffer pad made of the first hardness material, and the first hardness value of the soft buffer pad made of the first hardness material is less than the second hardness value of the buffer pad made of the second hardness material;

[0009] Headband assembly, the headband assembly is provided with a connecting part connected to the mask bracket, and a soft headband connected to the connecting part.

[0010] The double-hardness buffer pad breathing mask provided by the embodiment of the present application is provided with a soft buffer pad made of a first hardness material that fits the human face on the buffer pad bracket. The texture of the buffer pad material is soft, so that the wearer feels more comfortable. A buffer pad made of a second hardness material is provided between the soft buffer pad made of the first hardness material and the buffer pad bracket. Its hardness is greater than that of the soft buffer pad made of the first hardness material and has better elasticity. When wearing the breathing mask, by squeezing the buffer pad made of the second hardness material, it can produce a certain elastic deformation. On the one hand, it can make users with different face shapes better fit the buffer pad and better fit the human face. At the same time, the elastic pressure can provide a certain squeezing force to achieve a better sealing effect, reduce the generation of noise, reduce the discomfort brought to the user during the use of the breathing mask, and improve the auxiliary treatment effect.

[0011] Preferably, the soft buffer pad made of the first hardness material includes a nose pad portion that fits the nose, a lower pad portion that fits the chin or the upper lip, and a left pad portion and a right pad portion that are symmetrically arranged on the left and right sides and are respectively connected to the nose pad portion and the lower pad portion.

Since the shape of the nose part of each person varies the most during the process of wearing the breathing mask, during the wearing process, the deformation of the nose part of the breathing mask is the largest and the most difficult to control, resulting in the worst fit between the breathing mask and the nose part. By providing a buffer pad groove in the nose pad portion of the soft buffer pad made of the first hardness material in the direction of the buffer pad made of the second hardness material, the deformation of the nose pad portion can be adjusted by squeezing the buffer pad groove, and the deformation of the buffer pad groove is used to adjust the fit between the nose pad portion and the human nose.

[0012] Preferably, both the soft buffer pad made of the first hardness material and the buffer pad made of the second hardness material are made of silicone material.

The main problem is that although the breathing masks are provided with masks of different sizes for different age groups and can also be adjusted to a certain extent to generally meet the adaptation of the breathing mask to the human face. However, the shapes and sizes of different human faces vary greatly, and there are also significant differences in the height of the nose bridge. The existing breathing masks still have insufficient adaptation to the human face during use, resulting in poor sealing and relatively large noise generated by the outflow of gas. This kind of noise may seriously affect the sleep of some users who need to wear the mask for a long time, such as patients who need to wear it for several days, or the sleep of people next to them, and even affect the mood of the patients and people around them, leading to the patients being unwilling to wear it and affecting the treatment effect.

[0034] In response to the above problems, the present application provides a breathing mask with a dual-hardness buffer pad, such as Figure 1 、 Figure 2 、 Figure 3As shown, it includes a mask bracket 1.
