Description

Composite medical protective mask protective plaster

Technical Field

The utility model belongs to the technical field of medical protective facial mask accessory, concretely relates to compound medical protective facial mask protection card.

Background

The world health organization indicates that wearing the mask can help prevent the spread of certain respiratory diseases and has important significance for the global prevention and control of respiratory infectious diseases. This means that more patients need to wear protective and medical equipment and more medical staff need to take care and treatment tasks for the patient.

The N95 mask is the most commonly used medical protective equipment, and in order to protect the patient from virus infection, the N95 mask is designed as a Tight-fitting protective device (light-fitting protective), and the edge of the mask is tightly attached to the face by a 3D-shaped and moldable metal nose bridge strip and an elastic strip which maintains sufficient tension, so as to reduce the leakage caused by the gap between the mask and the face. Therefore, the mask should be inspected for its close contact every time it is used, so as to prevent harmful substances in the air from directly entering the mask without being filtered by the filter material, and affecting the health of human body. The world health organization simultaneously reminds that the correct use and treatment of the mask must be ensured to ensure that the mask is effective and to avoid increasing the risk of virus transmission due to incorrect use and treatment of the mask. When the mask is worn correctly, the end of the metal strip is firstly confirmed to be positioned above the mask, the metal strip is pressed to be tightly attached to the bridge of the nose, the ears are sleeved by a bandage, or two cords are tightened behind the brain, and the mask is ensured to completely cover the nose, the mouth and the chin. A mask that is used improperly may present a wearer with a greater risk than if the mask were not worn.

Because of this, the N95 mask can only protect against high strain, and wearing the mask for a long time can cause different degrees of pressure injury to the carina, such as auricle, bridge of the nose, cheekbones, etc., and the contacting portion of the face. Pressure injure (Pressure injure) refers to a local injury to the skin or subcutaneous soft tissue, usually located at the bony prominences or/and associated with iatrogenic devices. The lesion may be an intact skin or an open wound, and may be accompanied by a sensation of pain. Damage occurs from intense and/or prolonged pressure, or pressure combined with shear. Medical device-related pressure injury (compressive injury) refers to pressure injury produced by a medical device used for diagnosis or treatment. Such lesions typically exhibit a range or shape that is compressed by the medical device. The devices such as the N95 cover and the goggles which are used by medical staff in a large amount during epidemic prevention cause pressure injury consistent with the edges of the devices due to long-term action on the parts such as the ear corridor, the cheekbones, the nose bridge and the like, and can be regarded as instrument-related pressure injury.

Through reports from various media, or the in-person experience of the applicant wearing the N95 mask on his or her own, it has been found that pressure injuries are very common to medical staff and other wearers caused by wearing the N95 mask, particularly the skin at the nasal site, and that pressure injuries ranging from grade 1 to grade 4 may occur, such as non-albedo erythema, partial cortical defects with exposed dermal layers, pink or red wound bed, and tissue moisturization. Full cortical defect this stage of lesion has already exhibited a full cortical lesion, with subcutaneous fat (fat) and granulation tissue visible in the wound, and often exhibiting a rolled edge (rolled wound edge). Slough and/or eschar may also appear, or there may be a persistent, unrelenting, deep red, superior or purple skin discoloration, or separation of the epidermis, showing a dark-black wound bed or engorged blisters, suggesting pressure injury of the deep tissues. In addition to the damage to the skin itself, the accompanying pain also causes lasting psychological and physiological harm to the medical practitioner.

Therefore, how to reduce the pressure injury at the nasal bridge caused by wearing the N95 mask is an urgent problem to be solved. According to the national and international guidelines for stress injury protection, the key to preventing and treating device-related stress injuries is the removal of the source of stress. However, since medical staff and patients need to wear masks and goggles for a long time during epidemic prevention, and spray propagation and contact propagation are prevented, the method of removing the pressure source is obviously not suitable for the prevention of pressure damage associated with the N95 mask, and the method of reducing pressure or dispersing pressure is more suitable.

The mask nose bridge sponge strip sold in the market at present can improve the comfort of wearing the mask, but the safety and the effectiveness of the mask used for medical protective masks may have problems.

For example, the 3M N95 mask respiratory 1860 was produced by a manufacturer who did not consider the potential damage to the skin from the nasal metal nose bridge, and therefore the original product was designed with foam or sponge underneath the metal nose bridge. However, due to prolonged use and greater pressure, the nasal bridge strip has very limited effect on both skin damage and head and face pain. Of course, according to this design, again reflecting the proper dressing design from another aspect, does not affect the fit of the mask.

The nose skin protection device of the ideal medical protective mask needs to meet three requirements of mask skin fitness, skin protection and pain reduction. At present, the problem of pressure dispersion from a metal nose bridge strip can not be solved although a part of comfort problem can be solved by sponge strips in the mask designed by manufacturers or external auxiliary devices.
