Description

Special nose patch for mask

Technical Field

The utility model relates to a nose pastes the field, specifically is a special nose of gauze mask pastes.

Background

The pathogen new coronavirus is mainly carried out in form of droplet and close contact transmission, and highlights the importance of respiratory protection. The protective mask mainly comprises a medical surgical mask and an N95 mask which can effectively prevent the invasion of droplets carrying viruses in respiratory tract. However, in the clinical use process, because the edges of the two masks are only provided with metal or plastic shaping strips, the textures are hard and are not tightly attached to the face, so that the masks are easily affected by breathing or facial activities to generate gaps, generate fog, and cause the fogging of goggles to affect the visual field. In order to solve the problem, if the mask which is completely tightly attached is worn for a long time, the phenomenon that the skin around the mask, particularly the skin on the upper edge of the mask is tightened and scratched, and even the phenomena of skin pressure sore and skin breakage can occur.

In order to solve the above problems, medical staff have devised many solutions, such as modifying the inner lining of the sealing strip, or modifying the shaping strip into an inner lining, or replacing the plastic strip with a moisture absorbing strip, and also have modified the material of the mask to make it more breathable or designed air or air ducts on the mask to prevent the mist from blocking the view by changing the flow direction of the exhaled air. However, the above method either reduces the protective effect or makes the structure of the mask more complicated, and still cannot fundamentally solve the problem. Therefore, a simple mask sealing method is urgently needed clinically, and the requirements of both the protection effect and the anti-mist effect are met.

Disclosure of Invention

The utility model aims at providing a special nose pad of gauze mask to solve the problem that the above-mentioned background art pointed out.

In order to realize the purpose, the following technical scheme is adopted:

a special nasal paste for a mask comprises a back lining layer, a hydrocolloid layer and an anti-sticking layer; the nose patch is strip-shaped, the main component of the hydrocolloid layer is sodium hydroxymethyl cellulose, the hydrocolloid layer can absorb moisture and expand, the cushioning and sealing effects are achieved, the backing layer is attached to the upper layer of the hydrocolloid layer, two ends of the backing layer are trapezoidal, and the hydrocolloid covers most area of the backing layer; the upper layer of the back lining layer is adhered with an anti-sticking layer which is composed of a polyurethane film, and the surface is covered with non-setting adhesive.

Further improved, when the mask is produced, the hydrocolloid adhesive film and the anti-sticking layer are directly pressed or sewn at the edge of the upper part of the mask and are combined with the mask body, so that the good effects of preventing pressure sores and preventing fog are achieved.

Preferably, the nose patch has three specifications of 6 cm, 8 cm and 11 cm in length, 1 cm in width and 0.2-0.5 cm in thickness.

Further improved, the utility model can be used in N95 mask, medical surgical mask, KN95 mask, DS2 mask and FFP2 mask.

The utility model has the advantages that: the mask can be tightly attached to the face, no gap is formed no matter how deep and frequent the breathing frequency is, and therefore water vapor is prevented from entering the goggles; meanwhile, the hydrophilic property of the hydrocolloid can avoid the strangulation or pressure sore on the skin caused by wearing the mask for a long time; moreover, the applicable mask is wide in range and is not limited by the model of the mask.

Detailed Description

The invention will be explained and explained in more detail with reference to the drawings and exemplary embodiments. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. 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.

Example 1: referring to fig. 1 and 2, a special nasal paste for a mask comprises a backing layer 3, a hydrocolloid layer 2 and an anti-sticking layer 1, wherein the nasal paste is integrally strip-shaped, the hydrocolloid layer 2 mainly comprises sodium hydroxymethyl cellulose and can absorb moisture and swell, the backing layer 3 is attached to the upper layer of the hydrocolloid layer 2, two ends of the backing layer 3 are trapezoidal and made of PP non-woven fabric, and the hydrocolloid layer 2 covers most of the area of the backing layer 3; the upper layer of the back lining layer 3 is adhered with an anti-sticking layer 1 which is composed of a polyurethane film, and the surface is covered with non-setting adhesive. The utility model has three specifications of 6 cm, 8 cm and 11 cm in length, the width is 1 cm, and the thickness range is 0.2-0.5 cm.

Example 2: can directly install hydrocolloid adhesive film and antiseized layer 1 in gauze mask upper portion edge when producing medical disposable gauze mask, make disposable gauze mask from taking one kind and preventing the part that presses the sore, remedy the sealed effect of current gauze mask ideal problem inadequately.

The utility model discloses can be applicable to the gauze mask of different models, for example: n95 mask, surgical mask, KN95 mask, DS2 mask, and FFP2 mask.

The using method comprises the following steps: firstly, checking whether the disposable anti-fog nose-guard is intact, if so, tearing off the polyurethane film on one side of the non-sticky glue, attaching the polyurethane film to the middle part of the upper edge of the mask, then attaching the side covered with the hydrocolloid to the nose bridge and the cheeks on the two side faces of a wearer, then pressing the upper part of the mask by hands until the upper part of the mask is tightly attached to the panel, and finally finishing the shaping of the mask.
