Description

Breathing mask

The application requires on May 1st, 2006 to submit to, and application number is the priority of 60/796,994 U.S. Provisional Patent Application, and to introduce its full content referring to mode.

Background technology

Breathing mask is guarded in manufacturing industry, physical culture, and all found its practicality in the various application of daily life.In the application of these types, breathing mask filters out the pollutant of dust and other to help the more comfortable breathing on the part of wearing at user.Similarly, breathing mask has also been found its practicality in health care industry.At this on the one hand, the usefulness of breathing mask is that it can be set for gas that filtration breathed out by the wearer and be discharged into the antibacterial the environment or the quantity of other pollutant to minimize from user.Because the inpatient needs gnotobasis avoiding infection usually, and the inpatient often has impaired immune system and makes its easier infection, so be very important to this restriction of bacterial pollutant.In addition, because the inpatient can carry airborne bacterial pathogen usually, so breathing mask can also filter inhaled air avoid the pollutant effects that may find with the protection user in hospital environment.

Therefore present case is in medical health field; particularly in operating room, the medical personnel often uses breathing mask, and they must not various harmful diseases for example may be present in by the treatment intravital acquired immune deficiency syndrome (AIDS) of patient and hepatitis and other infectious disease to help protection.

Breathing mask is also for providing the tightening seal device to design.This sealing device can prove effectively aspect the propagation that prevents to reside in body fluid or the intravital pathogen of other liquid.Similarly, breathing mask designs for preventing that the intravital pathogen of airborne pathogen and/or liquid is transmitted to the medical personnel and/or propagating from the medical personnel.This sealing device can be used to help from being isolated dust wearer's inhaled air, particulate matter, perhaps other pollutant (that is to say, air during by breathing mask breathing mask play the effect of filter or otherwise help to isolate such material, dust, or pollutant).

Some breathing mask is set to hide the entire face of user and other breathing masks are set to only hide the nose and the mouth of user.In addition, breathing mask has been designed to hide the various piece of user face.For example, some breathing mask is set for the nose that hides user, eye, and mouth.The part that breathing mask hides nose and mouth usually by prevent antibacterial and other pollutant therefrom by but the material that allows air to pass through make so that user can be breathed.What be connected to breathing mask is the fixture that is used for the preceding width of cloth is fixedly connected to the user head.For example, can use manual frenulum, particularly for the health care breathing mask.For this purpose, breathing mask is placed on the user face then frenulum is stretched and fastens around the user head.Frenulum is fastened to user with breathing mask.

At present, disposable breathing mask, especially for industry or those disposable breathing masks of relevant purpose, the overwhelming majority comprises all that usually the elasticity faciola at two backs that are used to tie up to wearer's head and top is to guarantee to press close to and cooperate closely.This frenulum is difficult to place like clockwork and often landing, tumbles, and perhaps drops.And, such breathing mask may during exhaling, allow from the air that user pulmonary breathes out flow or be directed to user around eyes (for example, if the main body of breathing mask fail suitably to seal around its edge the wearer skin---this is easy to take place usually during the wearer has face action).If user has on protective eye lens, safety goggles for example, these have the air of dampness so, just may cause condensing on the surface of protective eye lens, and it is more difficultly seen clearly.And present respiratory face mask design may hinder the downward and peripheral visual field.

Needed breathing mask (and assembly, in the just following parts one or more) comprising: help to wear convenient and wear during the scalable or the elastic frenulum of comfortableness; And/or the guiding breath, guide the venthole of a part of breath at least away from the user eyes; And/or be easy to use and help to wear convenient and wear during the securing member of comfortableness; And/or be configured as and help breathing mask that protective eye lens and described breathing mask are worn together; And/or be fit to improve in the frenulum of breathing mask allotment property or as the bellows-type parts of a frenulum part, perhaps in the frenulum or as other likes of a frenulum part; And/or can be during use (for example from the outside expansible breathing mask part of state more flat between storage or delivery period, between transportation and storage life, be in certain concertina or bellows-type structure by the main body that makes breathing mask, but outwards expand during being adapted at using described breathing mask; Perhaps can fold---for example doubling---so that the main body of breathing mask can or store with flat relatively attitude transportation, but be fit to open/expand) for using by the main body that makes breathing mask.

Summary of the invention

We have determined multiple unique design structure, can help to improve to wear, and cooperate, and regulate sealing, comfortableness, style/aesthetic feeling and/or frenulum.

Various feature and advantage of the present invention will be introduced in the description part below.

Should be appreciated that scope and the border mentioned comprise all scopes that are positioned at it herein, also comprise being positioned at following or all the above numerical value in described border.For example, also comprise from 110 to 150,170 to 190 and 153 to 162 scope from about scope of 100 to 200.And, be approximately 7 the upper limit and also comprise and be approximately 5, be 3 and be approximately 4.5 the upper limit.

As mentioned above, a lot of existing breathing masks all are considered to uncomfortable or are difficult to wear and use.Parts that influence breathing mask comfort and convenience are to help the main body location of breathing mask and remain on frenulum on the wearer's face.As mentioned above, two elasticity faciolas main body of often being connected to breathing mask by one particularly is designed for the main body of the breathing mask that industrial class uses.These two frenulums be for around the back of wearer's head and top to assist in ensuring that and to cooperate closely.Unfortunately, this frenulum is difficult to place like clockwork and often landing, tumbles, and perhaps drops.

Breathing mask of the present invention comprises having the innovation material, the frenulum of shape, and/or connecting device (just securing member or fastening system).For example, a plurality of representative embodiment of the present invention comprise the frenulum that can connect or be fastened to breathing mask releasedly, thereby allow user to wear face shield more easily.For example, referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and representative embodiment shown in Figure 8.In each of these representative embodiment, the one or both ends of frenulum are not connected to main body (just suitable filtration of breathing mask by one, shielding, perhaps otherwise influence by breathing mask suck or the air of breathing out or the breathing mask part of at least a portion in one or more compositions in the gas).In certain embodiments, the width of frenulum is selected as making and is not easy to roll or move (for example frenulum shown in Fig. 1 2).In certain embodiments of the present invention, at least some parts of frenulum have about 0.5cm to the width between about 5cm.In other embodiments of the invention, at least some parts of frenulum have about 0.3cm to the width between about 3cm.It shall yet further be noted that as shown in Figure 1 frenulum part can be divided into two or more frenulums so that stablize breathing mask during use.Here frenulum part in wearer's ear portions from forming effective Y shape branch, or connection wye, wearer's ear is divided into the position of two frenulums near frenulum simultaneously, a frenulum extends below ear, and a frenulum extends above ear.

Can use different fastening systems.In the part embodiment that is introduced, frenulum is made of the flexible material (for example being fit to tensile non-woven material) that is fit to around head.The frenulum that is made of this material is connected to the frenulum secure component that can engage secure component corresponding on the breathing mask main body releasedly at its end.The frenulum secure component can be connected to frenulum with various modes commonly known in the art, and (for example, use is bonding; Welding; By importing heat energy or other energy with alloying material; By using mechanical fasteners frenulum is connected to frenulum secure component-for example, bolt, rivet, hasp, magic tape etc.; Perhaps other these class methods or the combination of method is as long as the frenulum secure component keeps being connected to frenulum between the operating period of the breathing mask of having used frenulum and frenulum secure component).Be fit to be engaged to releasedly the secure component of frenulum secure component, can be connected to the main body of breathing mask with identical or similar method.The main body of breathing mask, or its each several part, can be formed or cut forms (be included in to cut out in the described main body and be fit to hold for example opening of at least a portion of secure component).

In a scheme of the present invention, the frenulum secure component is the abundant rigid shape that can engage or be connected to the secure component on the breathing mask main body releasedly, and is for example circular, square, or other shapes.An example of the secure component on the breathing mask main body is abundant rigid shape, have opening and cavity, can insert the frenulum secure component by opening, can be (for example with the frenulum secure component, circular, square, or other shaped members) insert in the cavity and fix in position (for example when wearing this device, the tension force by frenulum is drawn in the frenulum secure component in recess or groove or other shapes that fixedly breathing mask and frenulum are in place to help; Fixedly the frenulum secure component is in place to help can certainly to use other method, magnetic force for example, and magic tape, gluing, metal or plastics hasp, bracelet etc.).In representative embodiment shown in Figure 1, the frenulum secure component is in the opening 6 that can be inserted in the secure component 8, and and secure component 8 be connected to the disk 4 of the main body of breathing mask 10 together.The cross section 14 of breathing mask main body shows a kind of of main body and is fit to self folding representative solution (for example providing the flat substantially shape that is used for transporting and/or using between the storage life).The foldable structure of breathing mask main body can be unfolded, and opens, or opens to be used as the structure on the part (for example being worn over the mouth of user, nose, and near facial zone) that is fit to be worn on the user face.

In certain embodiments, the secure component on the breathing mask main body also is suitable as venthole (gas that just helps to guide exhalation is by the secure component on the breathing mask main body or some other part and outwards enter hole in the external environment).In Fig. 1, venthole comprises the passage 12 that therefrom guides air.In certain embodiments, these holes help the eyes of mobile breath away from the wearer, thereby are used to reduce the expired gas scale of construction of the humidity between the various protective eye lens that the eyes that enter the wearer and wearer worn.As described in other places, the dampness in the breath can condense on the surface of this protective eye lens, and it is more difficultly seen clearly.And the breath that such hole can be used in guiding more volume flow passes through from the hole, rather than the main body by breathing mask is to external diffusion.In some cases, the hole, port, passage, perhaps opening can be covered, for example hides with porous or filter medium, leaks into the amount of the intravital special component of expired gas in the surrounding with minimizing.In other schemes of the present invention, port, passage, or other openings that comprise venthole can be rotated or change so that the wearer of breathing mask can change the direction of breath.For example, passage can be set in the disk and with wearer's face and the space fluid between the breathing mask inner surface and be communicated with, and described disk is adapted at the housing internal rotation to constitute air-out apparatus (perhaps, as mentioned above, be arranged in the secure component that is connected to breathing mask, and secure component is used as the receptor and the venthole of corresponding frenulum secure component simultaneously).Alternatively, the whole secure component that is connected to the breathing mask main body can be fit to rotate or rotation with respect to breathing mask main body self pivot.Also can select other structures for use, as long as at the of the present invention various schemes that comprise the scalable venthole, port, passage, opening, perhaps other structures that constitute ventholes are suitable for rotating or pivot rotates to change because the air that wearer's expiration of breathing mask discharges or the direction of gas get final product.

In some scheme of the present invention, venthole comprises check-valves, flank, and perhaps other allow air to flow along a direction, but reduce or stop gas along mobile this type of airflow apparatus of other directions.Such frame for movement is known to those skilled in the art.For example, venthole can be included in user and reduces when air-breathing or stop gas inwardly to flow by venthole and flow into airflow apparatus in the air volume between breathing mask main body and the user face.But when user was exhaled, this airflow apparatus allowed to breathe out by venthole in the air volume of gas between breathing mask main body and user face and enter the breathing mask user environment on every side.

In certain embodiments, the main body of breathing mask comprises two secure components (representing with labelling 8) in representative embodiment shown in Figure 1, wherein each secure component on the breathing mask main body all is positioned near the side of wearer's face when wearing breathing mask.In some scheme of the present invention, the secure component that is connected to the breathing mask main body also all is used as venthole.

In other schemes of the present invention, an end of frenulum can be connected to breathing mask main body one side by one, and the other end of frenulum terminates in the frenulum secure component place that can engage the corresponding secure component that is connected to the breathing mask main body releasedly.

Usually, the strap arrangement that is fit to be used in the breathing mask comprises frenulum; Be connected to the frenulum secure component of frenulum; With the secure component that is fit to be connected to the breathing mask main body simultaneously and engage the frenulum secure component releasedly.Mentioned frenulum in other places of the present disclosure, frenulum secure component and being fit to is connected to the representative embodiment of the secure component of breathing mask main body.And as described in other places, secure component can comprise venthole.Should note in some scheme of the present invention, the end of frenulum self is passed drawstring device for example by screw thread or is connected to other adapters of breathing mask main body, that is to say that the secure component that is connected to breathing mask is applicable to engage frenulum material self releasedly and need not frenulum is terminated in frenulum secure component independently for example in the plastic components of substantially rigid.

In some scheme of the present invention, frenulum comprises bellows-type device 20 as shown in Figure 2.The bellows-type device can be made of elastomeric material.And the bellows-type device goes for designing and mechanical stretching by its concertina.Any machinery of bellows-type device and/or elastic stretching can be selected so that its correspondence is different from the tensile tension force of frenulum self, that is to say, can select the bellows-type device when bearing motive power (for example making tensile active force), to make the stretching that it can be more more or less than frenulum self.The bellows-type device can improve comfortableness and controllability.And this device can for example carry out sports at some potential consumers of described breathing mask, and house decoration is perhaps worn breathing mask and carried out various other active consumers, and aesthstic attractive force is provided.In addition, the Producer of this breathing mask or distributors can give related brand name of breathing mask or the trade mark that this bellows-type device (and/or other features to introduce among the application) is a characteristic.And the color that can select the bellows-type device is to be used for providing higher aesthstic attractive force to breathing mask.For example, the bellows-type device can be made with orange plastics or other materials, and the remainder of frenulum is for being different colours (for example black) simultaneously.But should be appreciated that the color scheme that also can select other is to be used to provide aesthstic attractive force (comprise the color of bellows-type device and frenulum remainder is complementary).Should also be appreciated that color can be chosen as to the people around wearer or the wearer provides certain safe class or by the information of other standards of the Producer of government or other mechanisms or breathing mask or distributors's defined.
