Description

Disposable nasal umbrella device

Technical Field

The utility model belongs to the relevant field of medical protective equipment, more specifically relates to a disposable nose umbrella utensil, and it not only is suitable for and provides the reliable medical protection of high leakproofness under occasions such as disease diagnosis, treatment and nursing, can effectively play the effect of gentle expansion alar moreover for more accord with aerodynamics when the nasal cavity is breathed, ensured the ventilation effect who has more good travelling comfort.

Background

In the operation process of medical diagnosis, treatment, nursing and the like, necessary protection needs to be provided for medical staff, patients and the like; for this purpose, products such as medical protective masks are usually provided. However, the comfort, convenience and safety of protective articles have not been fully exploited. For example, users often get into the embarrassment of being forced to take off the mask and lose protection when eating and drinking water; or when the mask is not properly worn by an improper operation, there is a risk that bacterial virus in the air enters the nasal cavity through the gap between the mask and the face.

It was found that, in addition to protective articles such as medical masks, some products for nasal protection are disclosed in the prior art such as CN201320467395.7, CN200410037363.9 and CN201420121274.1, which can work well together with masks by being worn in the nasal cavity.

However, further studies have shown that the above-mentioned nasal protection products still suffer from the following drawbacks or drawbacks:

first, from the product application, the existing nose protection product is mainly designed for daily life filtration such as dust prevention, and is generally an appliance suitable for repeated use, or a filter part needs to be replaced when the nose protection product is used again. However, when such nasal protective products are used in medical diagnosis, treatment, nursing and other operations, effective protection against pathogenic microorganisms is practically impossible, and protective products such as respiratory infectious diseases are obviously not reusable or complicated disinfection treatment is adopted, and in the working practice of a large number of medical workers, it has been proved that the development of nasal protective products suitable for filtering pathogenic microorganisms well is becoming an urgent need.

Secondly, from the structural characteristics of the product, the main body of the existing nose protection product is usually an accommodating space with openings at two ends, the accommodating space is placed in a nasal cavity, and a replaceable filter layer is arranged in the accommodating space to play a role in filtering. However, on one hand, the filter component and the accommodating component of the nasal protection product are not integrally designed, and the whole tightness has defects; on the other hand, the arrangement mode of the filtering component and the structural design of the accommodating space are not safely and reasonably attached to the biological structure of the nasal cavity in the breathing process, so that the special filtering requirements of pathogenic microorganisms and the like cannot be effectively met.

Thirdly, from the working mechanism of the product, the product needs to have better aerodynamic characteristics after entering the nasal cavity to maintain good ventilation effect, but the existing product does not give enough consideration in this aspect. In particular, it is found in practice that respiratory tract infections, suspected patients or persons in close contact therewith often have or potentially have a certain level of breathing difficulties of their own. In this situation, there is also an urgent practical need for providing better wearing comfort and higher ventilation in addition to providing safe and reliable pathogenic microorganism filtration function.

Accordingly, how to more conveniently and efficiently solve the above-mentioned various needs is becoming one of the technical problems to be solved urgently in the medical protection field.

The design that the shell gradually increases from small to large and the part of the shell is provided with the bulge ensures that the nasal umbrella is not easy to fall off when the nasal cavity exhales. When in use, the arched string side is placed at the columella side of nasal vestibule, and the fan-shaped part is placed at the alar side of nose. And a support surface is arranged from the midpoint of the chord side to the opposite side of the fan shape to avoid the collapse of the shell. In addition, the flexible water-absorbable material can absorb a small amount of liquid or medicine, keep the nasal cavity moist and improve the defense capacity of the upper respiratory tract.

In addition, the outer surface of the canopy portion may be provided with folds for deforming before use or for facilitating removal of the nasal umbrella apparatus. The umbrella cover can also be used for generating some attachments, so that the umbrella cover can be conveniently taken out or fixed.

According to another preferred embodiment of the present invention, said canopy portion is slightly larger than the nostril and the cross-section of the nose piece in contact therewith. Wherein, the umbrella face can adopt biological glue class and outer nostril laminating, increases leakproofness. The umbrella surface can also extend in different shapes or add devices, so that the fixation and the sealing performance with external nostrils are further enhanced.

To sum up, according to the utility model discloses a disposable nose umbrella utensil product can effectively satisfy the medical protection usage of respiratory infectious disease class, has gained obvious improvement in the aspect of maintaining good ventilation effect and use travelling comfort simultaneously. The product has the following main technical characteristics in the whole aspect:
