Description

Deformable face frame

Technical Field

The invention relates to the technical field of medical instruments, in particular to a deformable face frame.

Background

A plurality of masks are available in medical treatment, some masks are anti-virus and some masks are dustproof, but the existing masks are not tightly attached to the face of a human body, so that dust and viruses enter respiratory tracts to cause the masks to lose due functions. At present, the problem has been noticed, and some measures have been taken, such as the mask is provided with an iron clip at the nose bridge, and the iron clip is pinched when the mask is worn to fit the nose bridge, but the iron clip will loosen and fatigue, and the iron clip cannot completely prevent dust and virus from entering from the gap between the mask and the face. The iron clip obviously cannot enable the gap between the mask and the face to be in a micron scale matched with the filtering capacity of the mask.

For example, in china, some medical staff wear a four-layer mask to prevent virus inhalation, but the mask still becomes infected with virus as a result, and the reason for this is that the mask is not well protected, but after wearing the four-layer mask, the ventilation capacity of the mask is poor, so that air directly enters from the gap between the mask and the face, which is worse than the effect of wearing a one-layer mask.

In a word, the existing mask is required to be worn more, the problem that the mask is simple is solved simply, the mask is not made according to the requirement, most people do not know how to wear the mask correctly, and even if the mask is worn according to the requirement, the mask is loosened by actions of speaking, coughing and the like, a gap is formed between the mask and the face, and the mask is also out of action.

Because human face shape is different, it is lower like the bridge of the nose of oriental, and the bridge of the nose of western people is higher, hardly accomplish a gauze mask and everybody's face and laminate completely, some people's face is wider in addition, and some people's face is narrower. It is difficult to make a face frame suitable for all human faces.

If the face frame only presses the mouth and nose parts, the difference of the human faces is not so large, but the area of the mask for ventilating is too small, so that people can feel that the breathing is not smooth, and the contact range of the face frame and the face is enlarged to increase the ventilating area of the mask. The invention can also be used in the labor protection field and the gas defense field.

Therefore, it is necessary to design a face frame suitable for all human face shapes to press the mask according to the attaching problem between the human face and the mask.

Preferably, the soft colloid is a ring-shaped colloidal silica.

Preferably, the hydropneumatic sac is a thin-walled sac body with an annular cavity.

Preferably, the liquid gas cell is not filled with gas and/or liquid in its cavity but is used after filling with gas and/or liquid or filled with gas and/or liquid in its cavity.

Preferably, the liquid air bag is used after the volume of the gas and/or liquid filled in the cavity of the liquid air bag at normal temperature and normal pressure is smaller than the maximum volume of the cavity of the liquid air bag which can be filled at normal temperature and normal pressure or the gas and/or liquid is not filled in the cavity of the liquid air bag, but the volume of the gas and/or liquid filled at normal temperature and normal pressure is smaller than the maximum volume of the cavity of the liquid air bag which can be filled at normal temperature and normal pressure.

The maximum radius of the liquid air bag is R after the liquid air bag is filled with liquid or gas, so that the liquid air bag can be filled in gaps between 0 and 2R. If the bag body is a multilayer liquid air bag and N layers of liquid air bags are arranged, gaps between 0 and 2NR of the bag body can be filled. The face frame sealed by the liquid air bag has the same pressure on all parts, and can not generate marks on the face.

Preferably, the liquid air bag is used after filling the cavity with gas and/or liquid at normal temperature and normal pressure, wherein the volume of the gas and/or liquid at normal temperature and normal pressure is one sixth to five sixths of the maximum volume of the cavity which can be filled at normal temperature and normal pressure, or the gas and/or liquid is not filled, but the gas and/or liquid at normal temperature and normal pressure is filled with the gas and/or liquid at normal temperature and normal pressure, wherein the volume of the gas and/or liquid at normal temperature and normal pressure is one sixth to five sixths of the maximum volume of the cavity which can be filled at normal temperature and normal pressure. For example, the maximum volume that can be filled inside the liquid gas cell is the volume of the liquid gas cell at which the gas and/or liquid pressure in the liquid gas cell is equal to one atmosphere at a temperature of 20 degrees celsius, i.e., the maximum volume of water that can be filled in the liquid gas cell. When in use, the volume of the gas and/or liquid filled in the cavity of the liquid air bag under normal temperature and normal pressure is less than the maximum volume of the cavity which can be filled under normal temperature and normal pressure. This is because the liquid-gas bag is a non-elastic sealed bag body, and if the liquid-gas bag is elastic, the gas volume in the liquid-gas bag is uncertain, and the liquid-gas bag can be filled with the whole liquid-gas bag. If the bladder is flexible, the bladder may be unfilled, and optionally filled with a gas and/or liquid in an amount of one third to one half, or even over-inflated, to a pressure greater than one standard atmosphere.

Normal temperature and pressure mean a standard atmospheric pressure and a temperature of 20 ℃. For example, the gas and/or liquid filled in the cavity of the liquid air bag can be gas, liquid or liquid plus gas, and the volume of the gas and/or liquid filled in the cavity of the liquid air bag refers to the sum of the volumes of the gas and the liquid, the volume of the gas with gas, the volume of the liquid with liquid, and the sum of the volumes of the gas and the liquid with both the gas and the liquid. The gas can be filled before sale, or when the liquid gas bag is used by a customer, when the liquid gas bag is provided with the filling hole 25, the liquid gas bag can be inflated and sold according to the inflation requirement of the liquid gas bag without the filling hole 13 when the face frame is sold, or can be sold without inflation, the liquid gas bag is inflated automatically when the face frame is used by a user, when the face frame is used, the liquid gas bag is folded and divided into two halves, one half is compressed and filled with no gas, the other half is filled with gas, and the compressed half is released, so that the whole bag body is filled with only half of gas. Because the liquid air bag is not full of air, the liquid air bag can be swelled at the concave place of the human body under the action of small external force, and can be shrunken at the convex place of the human body, so that the face frame body 1 is fully attached to the human body, and is completely sealed.

Preferably, the volume of the gas and/or liquid filled in the cavity of the liquid air bag at normal temperature and normal pressure is one third to two thirds of the maximum volume of the cavity filled at normal temperature and normal pressure or the gas and/or liquid is not filled but the gas and/or liquid filled in the cavity at normal temperature and normal pressure is indicated to be used after the gas and/or liquid is filled in the cavity at normal temperature and normal pressure, and the volume of the gas and/or liquid is one third to two thirds of the maximum volume of the cavity filled at normal temperature and normal pressure.

Preferably, the volume of the gas and/or liquid filled in the cavity of the liquid air bag at normal temperature and normal pressure is one half to two thirds of the maximum volume of the cavity filled at normal temperature and normal pressure or the gas and/or liquid is not filled but the gas and/or liquid filled in the cavity at normal temperature and normal pressure is one half to two thirds of the maximum volume of the cavity filled at normal temperature and normal pressure.
