CN2461589Y - Nose mask - Google Patents

Abstract

The utility model relates to a nose mask, which is arranged in nostrils of a human body for filtering air in a respiratory system. The nose mask is supported by a skeleton net. Fiber fabrics are attached inside and outside the skeleton net. A filtering ground substance is filled in the fiber fabrics. The utility model has the advantages of compactness and practicability. When the air in the respiratory system of the human body is filtered by the nose mask, the face appearance of the human body can not be shielded simultaneously. Effective protection for the respiratory system for people living and working in polluted air can be reinforced.

Description

Nose cup

The utility model relates to the protector of human respiratory, is applicable to that the crowd of life in the air pollution environment, work uses.

The protector of existing human respiratory mainly contains mouth mask, anti-poison respirator and breathing mask.Because the difference of protector function, its environment for use is also had nothing in common with each other.Except that breathing mask be under the higher special air environment of poison gas, use, mouth mask and anti-poison respirator are then using under general contaminated environment.The poison gas per unit volume concentration is not higher than 0.1% in the instructions for use surrounding air of anti-poison respirator, in the air oxygen per unit volume concentration not the end in 18%, environment temperature-30～+ 54 ℃; Mouth mask then is to use in generally with the air that dust granules pollutes or disease carrying germ pollutes.With regard to mouth mask, anti-poison respirator, in the air-polluting environment, bring fine protection to human respiratory in, also blocked people's face, people were both inconvenient, also not attractive in appearance when daily use.

The purpose of this utility model is to design a kind of safeguard function that mouth mask, anti-poison respirator can be arranged, and does not block the human respiratory protector of face simultaneously.

The novel purpose of these family expenses realizes by following measure: make the cylinder skeleton of nostril size diameter, closure of skeleton with wire or organic material; An outside turnup is used the rubber edge sealing.

In above-mentioned cylinder skeleton inboard or the outside adhere to one or more layers artificial or natural fabric, fill filter substrate in the fabric.

Above-mentioned filter substrate adopts fibrous material when Chalk-dust filtering, germ; When filtering toxic gas, adopt absorbent charcoal material or other filtering material.

Principle in utility model is: according to human oral cavity when closing; self can prevent dust, germ and have poisonous weeds gas to enter respiratory system by the oral cavity; in the ordinary course of things; the air of human body respiration mainly is to pass through the nostril; thus; as long as perform the protection in nostril, human respiratory is well protected, the human body face just can not be subjected to large-area blocking yet.

Description of drawings is as follows:

Fig. 1 is the three-dimensional appearance structural representation of utility model,

Fig. 2 is the cross-sectional view of utility model,

Fig. 3 is the position view of utility model in nasal cavity,

Fig. 4 is the position view of utility model in nasal cavity;

Coding is respectively in the accompanying drawing: 1 nose cup, 2 skeletons, 3 cushion rubbers, 4 fabrics, 5 filter substrate, 6 vestibulum nasis, 7 nasal cavities.

Shown in Fig. 1 to 2, nose cup 1, by skeleton 2, cushion rubber 3, fabric 4 and filter substrate 5, four parts combine.

As shown in Figure 3, nose cup 1 is placed in facial two nostrils, and what be exposed at the outside, nostril has only cushion rubber 3, and fabric 4 does not only block human body face, and not obvious, outstanding.

The colour planning that nose cup is exposed at the cushion rubber 3 of outside, nostril becomes human body complexion; Fabric 4 is designed to black, makes people's naked eyes can not tell the other side outside two meters and whether wears nose cup, closely watches, and nose cup is also very natural, proper at human body face.

As shown in Figure 4, nose cup 1 does not contact with other nasal cavity tissue at nasal cavity 7 inner vestibulum nasis of living in 6 positions, can not change the physiological function of interior airflow direction of nasal cavity and schneiderian membrane tissue.

Skeleton 1 has plasticity, can change with nostril vestibular 6 change of shape, makes not extruding of nostril, the discomfort sensation that acid is expanded.

Nose cup can be used with water or the water-soluble dropping liquid that is made into various fragrance, and the nose cup that splashes into liquid has also increased the humidity that sucks air when improving filter effect, satisfy the requirement of human body to air humidity, stable and mediator's mood.

Nose cup and various volatile medicine are used, and the direct effect on human body respiratory system of medicine, blood and brain are the treatment of relevant disease, and a kind of new route of administration is provided.

The nose cup expiratory resistance is less than 49.0 (handkerchiefs), and inspiratory resistance is less than 78.0 (handkerchiefs), and protection time was greater than 10 minutes, and air leakage factor is less than 1%; Nose cup diameter 5-10mm, height 5-12mm.

The utility model is small and exquisite, practical, carry, easy to use, economical with materials, with low cost.

Utilize this nose cup, when the human respiratory air was filtered, the human body face can not be blocked, and had strengthened the people of life in contaminated air, work, to effective protection of respiratory system.

Claims (3)

1, a kind of nose cup, be arranged in the human body nostril, the respiratory system air is filtered, it is characterized in that (2) closures of cylinder skeleton, an outside turnup, and, in skeleton (2) inboard or outside attachment fiber fabric (4), in fabric (4), fill filter substrate (5) with cushion rubber (3) edge sealing.

2, nose cup according to claim 1 is characterized in that skeleton (2) adopts wire or organic material.

3, nose cup according to claim 1 is characterized in that filter substrate (5) adopts fibrous material or absorbent charcoal material.
