The structure of the medical protective mask for preventing pressure sores according to the present invention will be described in detail with reference to the specific embodiments.

Example one

As shown in fig. 1, for the medical protective facial mask's of preventing pressing sore of this embodiment structural schematic diagram, can know from the figure, the medical protective facial mask of preventing pressing sore of this embodiment includes gauze mask body 1, nose clip 4, in gauze mask body 1 inboard and near its marginal place set up first soft silicone foam dressing structure 3, it is the inboard that the ring encircles gauze mask body 1, and includes soft silicone wound contact layer 32, can paste in user's face through soft silicone wound contact layer 32 to let whole gauze mask cover in user's face.

Wherein, whole medical protective facial mask is left right folding symmetrical structure, and its gauze mask body 1 includes the filter layer, and this filter layer is the melt-blown material layer 12 of being made by superfine polypropylene fibre melt-blown material to can prevent coronavirus. And the nose clip 4 on the gauze mask main part can adopt aluminium system nose clip (can refer to the similar gauze mask structure of prior art), is located the position of upper and middle part of the gauze mask body, and during the preparation, the nose clip is about 9X 1cm long, and it can be moulded according to the nose type that the user is different, lets the gauze mask body and nose type laminating, and leakproofness, protective effect are better.

Specifically, the mask body 1 of the present embodiment adopts an inner, middle and outer three-layer structure, as shown in fig. 3, which includes: an inner layer 11 for contacting the face of a user, located inside the layer of meltblown material 12; an outer layer 13 disposed outside the meltblown material layer 12; wherein the inner side of the inner layer 11 is bonded to the outer side of the first soft silicone foam dressing structure 3.

When the sanitary napkin is manufactured, the inner layer 11 can be made of sanitary gauze or non-woven fabric, the outer layer 13 can be made of non-woven fabric or ultra-thin polypropylene melt-blown material, the middle layer is a melt-blown material layer 12 made of ultra-thin polypropylene fiber melt-blown material, and the three layers are sealed through thermal plastic. The manufacturing process of the mask body 1 may be the same as that of the prior art, and will not be repeated here. The mask body of the embodiment is provided with the melt-blown material layer, so that respiratory infectious diseases, such as neocoronary pneumonia, can be effectively prevented.

The first soft silicone foam dressing structure 3 of the present embodiment adopts a structure as shown in fig. 4, which includes: a soft silicone wound contact layer 32 with self-adhesion, a protective film 31 which is arranged on the inner side of the soft silicone wound contact layer 32 and can be torn off, an absorption layer 33 which is arranged on the outer side of the soft silicone wound contact layer 32 and is made of polyurethane foam, and an outer cover film 34 which is arranged on the outer side of the absorption layer 33 and is made of a breathable and waterproof material. The outer side of the outer cover 34 and the inner side of the inner layer 11 of the mask body 1 are bonded together by medical adhesive, and the removable protective film 31 needs to be removed from the inner side of the silicone wound contact layer 32 when the mask is used, so that the inner side of the silicone wound contact layer 32 can be adhered to the face of a user.

During the preparation, first soft silicone foam dressing structure 3 of this embodiment is the annular, its shape is the same with the shape at gauze mask body 1 edge, but the size is less than the size at gauze mask body 1 edge, certain thickness has, paste in user's facial back, can make the gauze mask balanced to user's facial pressure, can effectively cushion partial pressure, and the soft silicone wound contact layer 32 of soft silicone foam dressing structure can paste repeatedly, and viscidity is strong, can make gauze mask inseparable with the facial laminating of user, and the leakproofness is good, effectively prevents gas leakage.

Example two

As shown in fig. 2, a schematic structural diagram of the medical protective mask for preventing pressure sores in this embodiment is shown in fig. 2, and it can be seen from fig. 2 that the structure of the medical protective mask for preventing pressure sores in this embodiment is substantially the same as that of the first embodiment, except that the first soft silicone foam dressing structure 3 is disposed on the inner side of the mask body 1, the second soft silicone foam dressing structure 2 is disposed on the inner side of the mask body 1, and the second soft silicone foam dressing structure 2 is disposed on the inner side of the mask body 1 and between the edge of the mask body 1 and the first soft silicone foam dressing structure 3, so as to prevent the mask from being unable to be tightly attached to the face of the user due to insufficient viscosity of the first soft silicone foam dressing structure 3.

The second soft silicone foam dressing structure 2 of this embodiment is also ring-shaped, and its shape is the same as the shape of the edge of the mask body 1, but its size is smaller than the size of the edge of the mask body 1 and larger than the size of the first soft silicone foam dressing structure 3, and it also adopts the four-layer structure same as the first soft silicone foam dressing structure 3 in the first embodiment, and it is attached to the face of the user through the soft silicone wound contact layer, and the structure will not be described in detail here.
