Clamping head capable of improving air permeability of medical plane mask

Abstract

The invention belongs to the technical field of medical masks, and relates to a clamping head capable of improving the breathability of a medical planar mask. The clamping head comprises a baffle, a nose support is arranged at the top of the baffle, and a mask body clamping groove is formed in one side of the top of the nose support; a plurality of sets of air holes are evenly formed in the side, away from the mask body clamping groove, of the baffle in an array mode, the air holes are communicated with one another through connecting pipes, upper supporting rods are hinged to the two sides of the baffle, upper ventilation pipes are arranged in the upper supporting rods, one ends of the upper ventilation pipes are communicated with the connecting pipes, and dehumidifiers are arranged in the upper ventilation pipes. The clamping head not only can effectively disperse expiration and inspiration of a wearer and prolong the service life of the mask, but also can adsorb water vapor in the air, can improve the clamping force of the upper supporting rods on the wearer in the expiration and inspiration processes and ensure the fastening effect, and can also be matched with the expiration and inspiration to squeeze and massage the wearer, so as to improve the wearing comfort and tightness.

Description

technical field [0001] The invention belongs to the technical field of medical masks, in particular to a clamping head capable of improving the air permeability of medical flat masks. Background technique [0002] Medical masks are mostly made of one or more layers of non-woven fabrics. The main production processes include meltblown, spunbond, hot air or acupuncture, etc. It has the effects of resisting liquids, filtering particles and bacteria, and is a medical protection. Textile and medical masks are composed of a mask body and a tension belt. The mask body is divided into inner, middle and outer layers. The inner layer is made of skin-friendly material, the middle layer is an isolation filter layer, and the outer layer is a special antibacterial layer. [0003] Chinese invention patent CN113017176B discloses a clamping head that can improve the air permeability of a medical flat mask. The upper end of the liner body is provided with a liner head, which can be folded alo...

Problems solved by technology

[0003] Chinese invention patent CN113017176B discloses a clamping head that can improve the air permeability of a medical flat mask. The upper end of the liner body is provided with a liner head, which can be folded along the second crease line; the lower end of the liner body is provided with a The liner is opened, and the two sides of the liner opening are respectively provided with a first tie bar and a second tie bar; the outer end of the first tie bar is provided with a first buckle, and the outer end of the second tie bar is provided with a second buckle; A first crease line is provided at the junction of the first brace and the second brace and the pad main body, and the first brace and the second brace can be folded in the same direction along the first crease line; the pad The main body is rolled up in a semi-cylindrical shape in the direction opposite to the folding of the first tie bar and the second tie bar, and the first buckle and the second buckle on the first tie bar and the second tie bar are oppositely buckled together, The opening of the liner is bent to form a semicircle and fixed; this application cannot achieve adaptive dispersion of the inhalation and exhalation gas of the wearer with the mask, so the wearer will wear it for a long time and cause excessive saliva or water vapor. Attached to the inner side of the clamping head to cause pollution, thus affecting subsequent use

[0004] At the same time, existing masks cannot adapt to wearers of various face shapes. Because the length of the tension band of the mask is certain, and the tension band is an elastic band, the wearer will appear to wear too tight or too loose, which seriously affects wearer comfort

[0005] Moreover, wearing the same mask for a long time will cause the performance of the mask to decline, and it will no longer have the required protective performance. However, the existing masks do not have the effect of reminding the wearer to replace them. They can only be replaced selectively by themselves, which greatly increases possibility of cross infection
