Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Examples

When using breathing machine face guard, the main pressurized position of patient's face is bridge of the nose and alar both sides respectively, so in order to avoid the waste of material and the facial too much cover of patient to make its skin surface appear impaired condition, the utility model discloses a nose pad wholly is the style of calligraphy of falling V, as shown in fig. 1, a breathing machine is nose pad for face guard, including top 1, left end 2 and right-hand member 3, top 1, left end 2 and right-hand member 3 structure as an organic whole. Wherein the left end 2 and the right end 3 respectively cover the cheeks at the two sides of the nose of the patient, and the top end 1 transversely covers the bridge of the nose of the patient, so that the face of the patient is directly pressed on the side edge of the mask when the respirator mask is used. According to human nasal part shape, traditional nose pad designs into the triangle-shaped, and the purpose is in order to cover patient's nose comprehensively, nevertheless because the human bridge of the nose has a take the altitude, and everyone's nasal part shape is different, can appear the condition that the nose pad part arches or sticks up the limit when covering, leads to its unable complete laminating nasal part for the patient is wounded the facial part healing slow, is unfavorable for the recovery of the state of an illness. So the utility model discloses top 1 at the style of calligraphy of falling V nose pad still is equipped with a plurality of one-way openings 8 outwards, as shown in fig. 2, after setting up a plurality of openings 8, because the top is not the laminating of whole piece formula, medical personnel can do corresponding adjustment when pasting top 1 according to the particular case of patient's nasal part, avoid the nose pad to appear the part hunch-up, guarantee the complete laminating of nose pad and patient's face, be favorable to patient to receive the quick recovery of the surface of a wound.

Specifically, the nose pad is divided into two layers, as shown in fig. 3, a bottom layer 4 contacting with the face of the patient and a top layer 5 facing the inner wall of the respirator mask, and the bottom layer 4 and the top layer 5 are adhered together by medical adhesive. Bottom layer 4 includes a dressing region 41 and an adhesive region 42 (similar in construction to a wound covering) disposed about dressing region 41. Dressing district 41 is used for preventing and resumes the pressure sore phenomenon that patient's face appears, and pasting region 42 is convenient for the nose pad and pastes and fix on patient's skin surface, still be equipped with on bottom 4 rather than tearing the pad pasting 6 of pulling the dismantlement, the nose pad of being convenient for protects bottom 4 when not using, avoids contacting with the external world.

Further, top layer 5 is the buffer layer, because the side of face guard has certain width, can carry out direct extrusion to the nose pad, and the setting of buffer layer can avoid face guard direct extrusion bottom 4's dressing district 41 and adhesion area 42, leads to appearing pasting the tension, and dressing district 41 and the facial excessive clench of patient, the condition of uncomfortable sense appears in the patient. Specifically, the buffer layer is made of medical film, and the foam is filled in the buffer layer, because the foam of the top layer 5 is directly extruded by the side edge of the buffer layer after the mask belt is worn, the buffer layer is used for buffering the pressure on the back face of the patient wearing the mask, and the phenomenon of air leakage can be effectively prevented. And because under the condition that the temperature is lower, because patient's spontaneous breathing, the inside steam that can appear of face guard, if not in time clear up steam, breed the bacterium in the face guard, will make the patient receive the infection of virus, aggravate the state of an illness. Therefore, the top layer 5 is filled with active carbon, which can absorb the water vapor generated in the mask in time, prevent the discomfort of the patient caused by the water vapor condensed in the mask, effectively avoid the breeding of bacteria and reduce the harm to the patient.

Further, still outwards extend on the left end 2 and the right-hand member 3 of nose pad and be equipped with outstanding section 7, outstanding section 7 is convenient for medical personnel to tear the pad pasting 6 back of covering on its bottom 4, and handheld nose pad pastes it in patient's skin surface, effectively avoids medical personnel hand direct contact nose pad bottom 4, causes the bacterial growing of bottom 4, finally leads to the facial impaired condition of patient.

Furthermore, because the nose pad that uses on the market at present often adopts gauze or other software materials to make, though when the cooperation breathing machine face guard uses, can reduce the sense of squeezing that the face guard brought to a certain extent, when changing the nose pad, because the reason of preparation material, can cause the painful sense of tearing to patient, especially to younger children patient, the painful sense that produces when tearing makes medical personnel be not convenient for take off the nose pad, so increased the time of changing the nose pad. Based on this shortcoming, the utility model discloses dressing district 41 of nose pad bottom layer 4 adopts hydrocolloid dressing preparation to form, because hydrocolloid's special property, so when tearing the nose pad change of its preparation, the patient can not have strong painful sense, and the medical personnel of being convenient for take off it from patient's nose, and because its inside enzyme that contains endogenesis, can promote fibrin's dissolution and be convenient for clear away the necrotic tissue in patient's face, more do benefit to the compressive wound, the impaired skin tissue of being convenient for is restoreed and is good for.

Parts not described in the above modes can be realized by adopting or referring to the prior art.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
