Problems solved by technology

[0003] This type of mask can block some bacteria, viruses, dust or sundries. The hospital environment is complex and there are many viruses. The bacteria and viruses attached to the mask are easy to cause cross-infection. It is very easy for medical staff to cause their own viruses in the process of helping patients. , and will bring secondary harm to the patient

Abstract

The invention relates to the technical field of medical supplies, in particular to a novel antibacterial surgical protective mask which comprises an outer layer, a middle layer and an inner layer. Thepreparation raw material of the outer layer is a hydrophobic blended polypropylene material; the middle layer is an antibacterial melt-blown layer or an antibacterial nano-film layer; and the inner layer is a water-absorbing non-woven fabric layer. The silver fiber or silver-copper fiber material of the novel antibacterial surgical protective mask has a killing effect on bacteria and viruses; therefore, when bacteria and viruses fall on the mask, the bacteria and viruses can be killed by silver ions or silver-copper ions, the mask has the antibacterial effect which is not achieved by an original mask, medical staff can be better protected, the risk of cross infection is reduced, and the service life of the mask can be prolonged.

Description

technical field [0001] The invention relates to the technical field of medical care products, in particular to a novel antibacterial surgical protective mask. Background technique [0002] At present, masks on the market generally adopt a multi-layer structure, referred to as SMS structure: the inner and outer sides are a single-layer spunbond layer (S); the middle is a melt-blown layer (M). Among them, the outer layer is a non-woven fabric with waterproof treatment, which is mainly used to isolate the droplets sprayed by the patient; the middle melt-blown layer is a specially-treated melt-blown non-woven fabric, which has good filtering and shielding properties. , heat insulation and oil absorption; the inner layer is ordinary non-woven fabric, which plays the role of water absorption. Although the spunbond layer (S) and meltblown layer (M) of the mask are both non-woven fabrics, and the raw materials are polypropylene, the production process is different. The fiber diame...
