Description

A dysmorphism foam dressing for preventing sore is pressed to face

Technical Field

The utility model belongs to the technical field of medical supplies, especially, relate to a dysmorphism foam dressing for preventing sore is pressed to face.

Background

Medical mask such as N95 mask that vast first-line medical personnel must wear high gas tightness carries out effectual virus protection work, and must reduce the risk of occupational exposure through increasing the pressure of mask edge (including the plastic metal of nasal wing part) and skin. The blood flow change will be more obvious when the skin of the human body is pressed for 2 hours, and medical care personnel at the epidemic prevention front line must be subjected to the pressure from the mask for a long time, so that the pressure sores and the ulceration of the nasal wings, the cheeks and the like are caused.

The pressure sore prevention material is added on the edge of the mask with high air tightness such as an N95 mask which is conventionally used at present. The concrete shape of the pressure sore prevention material is based on bony marks of the nasal alar part, the cheek, the chin and the like; the material has the buffer function and the skin-friendly function, and can play the roles of preventing pressure sores and air leakage;

the existing mask adopts an extensible rubber rope sleeve joint part or a hangers type fixing mode in order to ensure that a mask main body is firmly fixed on the face of a human body in the wearing process, and the mode is different in the fat and thin body types of people in the actual using process, so that the tensile pressure of a rope strip in the fixing process can be larger for users with larger faces, the pressure sore of a larger face area is generated due to the fact that partial area blood does not circulate due to the compression force of the head and the ears of the human body, discomfort is brought to the users, and the using requirements of the users cannot be met;

simultaneously to some users who wear glasses, the gas part of human exhalation flows by gauze mask edge, because human exhalation gas temperature is on the high side, to with some cold areas or cold season user, can make glasses lens atomizing when the gas of human exhalation and outdoor difference in temperature are great, causes the vision fuzzy, influences daily work.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the technical problem and providing a special-shaped foam dressing for preventing facial pressure sores.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a dysmorphism foam dressing for preventing face pressure sore, dysmorphism foam dressing is rectangular form, dysmorphism foam dressing includes the cheek portion of nose portion and nose bridge portion both sides, the epirelief in the middle of the nose bridge portion, the nose portion with the junction of cheek portion is recessed, it is concave on the bottom of dysmorphism foam dressing, the side edge thickness of face cheek portion reduces gradually, be equipped with horizontal bridge of the nose strip on the internal surface of dysmorphism foam dressing and paste the groove, the internal surface of dysmorphism foam dressing is in bridge of the nose strip pastes the inslot and the following part of bridge of the nose strip paste the groove all is equipped with the viscose coating.

Preferably, the depth of the nose bridge strip sticking groove is gradually reduced from bottom to top.

Preferably, the special-shaped foam dressing comprises a chemical fiber layer and a polyurethane foam dressing layer from outside to inside, and the surface of the viscose coating is provided with release paper.

After the technical scheme is adopted, the utility model has the advantages of as follows:

when the special-shaped foam dressing is used, the isolating paper is torn off at present, the nose bridge strip on the mask is stuck in the nose bridge strip sticking groove, and then the special-shaped foam dressing is tightly stuck with the mask, so that the effect of avoiding pressure damage to the face of a person can be achieved; in addition, the thickness of the side edge of the cheek part is gradually reduced, so that a large gap between the mask and the face of a person caused by the fact that the side edge of the special-shaped foam dressing is thick can be avoided, and germs are prevented from entering the mask.

Drawings

Fig. 1 is a schematic structural diagram of a special-shaped foam dressing for preventing facial pressure sores according to the present invention;

in the figure:

1-bridge of nose; 2-cheek part; 3-nose bridge strip sticking groove; 4-viscose coating.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a shaped foam dressing for preventing facial pressure sores, which is in the shape of a long strip, includes a nose bridge 1 and cheek portions 2 on both sides of the nose bridge 1.

The middle of the nose bridge portion 1 is convex upwards, the joint of the nose bridge portion 1 and the cheek portion 2 is concave downwards, and the bottom end of the special-shaped foam dressing is concave upwards. The special-shaped foam dressing is matched with the face of a person in shape, so that the face of the person, the special-shaped foam dressing and the mask/face mask are well attached.
