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 front panel 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 help breathing mask shape 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.

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 the frenulum with innovation shape, and/or coupling arrangement (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).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 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, grappling, 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 (comprise cutting out and be fit to hold for example intravital opening of described master 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 theopening 6 that can be inserted in thesecure component 8, and andsecure component 8 be connected to thedisk 4 of the main body ofbreathing mask 10 together.

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 and outwards enter hole in the external environment).In Fig. 1, venthole comprises thepassage 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.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 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.No matter secure component is one or a plurality of, wear or use the convenience degree of face shield and/or the ability of giving vent to anger of breathing mask preferably to improve, for the enhancing advantage, secure component is arranged in the breathing mask main body so that the tailing edge of secure component is positioned within the 3.75cm of breathing mask main body tailing edge, 2.5cm within, within the 1.25cm and 0.625cm within the scope of 2.5cm, can be favourable.

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.At the frenulum of all having mentioned everywhere 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 everywhere, 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.Can select any machinery of bellows-type device and/or elastic stretching 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.Bellows-type device device can improve comfortableness and controllability.And this device can for example carry out sports at some potential consumers of described breathing mask, house decoration, and various other the active consumers that perhaps wear breathing mask provide aesthstic attractive force.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 different colours (a 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.

Bellows-type device 20 shown in Fig. 2 is examples that are different from the machinery or the elastomeric element of frenulum self major part.Also can select to be suitable as in other this base part, particularly strapping system the part (the tensile part of response that just is different from bellows-type device or miscellaneous part in the frenulum) of independent response external influence power.For example, frenulum can comprise the more inflexible frenulum secure component near its end, has the first discontinuous length of first elastic first material and has the second discontinuous length of second elastic second material.Perhaps, for example the bellows-type device 20 shown in Fig. 2 can replace with compare the discontinuous length with different elastic materials with the remainder offrenulum 22.

In some scheme of the present invention, illustrating typically in Fig. 3, twofrenulums 30 and 32 include the frenulum secure component that can engage the corresponding secure component that is connected to the breathing maskmain body 34 releasedly.Representative solution shown in Fig. 3 also shows two optionally near thetie 36 of frenulum secure component, here is the bellows-type device.In the illustrated scheme of the present invention, thesecure component 34 that is connected to the breathing mask main body is also with acting on the venthole that port or passage are represented.Although illustrated scheme shows two frenulums, but frenulum (for example can constitute an assembly, suspensorium is connected at the back with frenum-for example, be similar to the side of letter " H " in back formation owing to connect suspensorium and frenum in some way).Otherwise, two secure components independently, each all is similar to thesecure component 8 shown in Fig. 1, also can be connected to each side of breathing mask main body.

Another representative solution shown in Fig. 4 shows uses the main body that is connected to the breathing mask of two independent frenulums with the similar frenulum secure component of above-mentioned frenulum secure component.In the present embodiment, frenulum further comprises thedrawstring device 40 of the additional flexibility that allows the adjusting frenulum.Fig. 5 shows similar scheme of the present invention, also has drawstring device 50.In fact, frenulum is not connected to frenulum secure component (it comprises the drawstring device that is fit to engage releasedly frenulum self) by one.

In another representative solution of the present invention, as shown in Figure 6,frenulum 60,61,62 and 63 are connected to the main body of breathing mask by one.Every pair of frenulum all is connected to assembly, makes up each assembly for example to be engaged with each other with illustratedbracelet 65 in the position near the wearer's head back side of breathing mask releasedly when wearing breathing mask.In the illustrated scheme of the present invention, the main body of breathing mask comprises not theventhole 67 with the secure component one.

In some scheme of the present invention, the main body of breathing mask adopts planar structure when being adapted at transportation or storage, but can open it in use, unties, and perhaps otherwise launches, so that main body is adapted to fit on some part of user face.

In other schemes of the present invention, venthole device as shown in Figure 7 and Figure 8 is used in the breathing mask of the present invention.Fig. 7 shows the different parts of this venthole scheme.Interior hole body 70 in this representative solution has oval in shape, but other shape also is possible (for example, circle etc.).Interior hole body is connected to or is set to the inner surface near the breathing mask main body.In a kind of scheme of the present invention, the main body of breathing mask is cut in advance has an opening, inserts hole body in the part by this opening.For example, this opening can be set at position near near the body rim the breathing mask wearer ear (for example, be similar among Fig. 1fastening firmware 8 residing positions).Although frenulum can be connected to a side of breathing mask by one, and be connected to the opposite side of breathing mask releasedly, but in some scheme of the present invention for example the venthole device in the representative solution shown in Fig. 7 and Fig. 8 can be connected to the both sides (this device comprises the secure component that can engage the frenulum secure component releasedly) of breathing mask.In of this sort scheme, breathing mask can have the pre-cut opening in the both sides of breathing mask main body, thereby allows venthole is connected to the both sides of breathing mask main body.

For theinterior hole body 70 shown in Fig. 7, the interior holebody wheel rim 72 that projects upwards from interior hole body can pass that the pre-cut opening is inserted in the breathing mask main body, andmarginal portion 74 is abutted against at least a portion of breathing mask body inner surface.What be connected towheel rim 72 iscrosspiece 76, it is used as usually: (1) helps flow (by blocking some part of theopening 78 that therefrom flows through air) of guiding exhalation air, and/or (2) can be inhaled into by venthole as stoping or blocking air when the people is air-breathing at least in part, but (for example when exhaling, the people allows air by the derivative barrier film of venthole, thin film, substrate, or composite diaphragm) junction point.For example, hide the barrier film that opening 78 also only is connected tocrosspiece 76 fully, can be as the removable thin slice that pulls to opening 78 edges when the people who uses breathing mask is air-breathing, thus blocking-up or stop inside air-flow (thereby and obtain to make the benefit of the material of inhaled air by being used to make the breathing mask main body); But when the user of breathing mask was exhaled, the edge of opening that barrier film is never connected thin slice pushed away, thereby allowed air to send by the opening of venthole.

Interior hole body 70 is formed as and/or introduces parts usually, so that it can engage withouter hole body 84 and/or cooperate.Therefore, in the representative solution of venthole shown in Figure 7,outer hole body 84 comprises the outer holebody wheel rim 86 of installing and engaging around interior hole body wheel rim 72.And wheel rim can be designed as each other mechanical engagement so that interior hole body and outer hole body are not easy between the operating period and break away from each other at breathing mask.For example, the includable hole body of the wheel rim of interior hole body and outer hole body top is placed outer hole body and is engaged flanged type structure (being similar to for example snap-in fasteners) in place when pressing down.A lot of such mechanical connections all are known and can be used for this purpose.Also can use other method that interior hole body and outer hole body are connected to each other, and be connected to the main body (for example, making to stick with glue welding, heat bonding etc.) of breathing mask.

The representative solution ofouter hole body 84 shown in Fig. 7 also comprises and main outer hole body opening is divided into two independentlyseparators 88 of air duct 90.According tointerior hole body 70 towards, and interiorhole body crosspiece 76 whether hide at least in part above or belowair duct 90, user or Producer can be by required direction guiding breath (guiding parts wherein at least).

Note also separator not being set.Perhaps also can use other structure or shape so that Producer or user can select with parts be connected to the venthole device with along required direction (for example away from glasses; if the user of breathing mask also wears glasses or other eye protection device; warm humid gas may condense on protective eye lens or eye protection device surface; thereby make it more be difficult to see clearly) guide breath, or guide a part wherein at least.

The representative solution of air vent device shown in Fig. 7 also comprises frenulum secure component 100.Representative solution 100 shown in Fig. 7 has leg-of-mutton shape usually, and tworectangular channels 102 and 104 that all are fit to hold frenulum are arranged.The frenulum secure component also comprises theopening 106 that is fit to engage releasedlyouter hole body 84, and it uses to link up with assecure component 92 in representative solution shown in Figure 7 and engages opening on the above-mentioned frenulum secure component.

These three parts are engaged with each other in being combined into air vent device 110.Should be noted that in the view of thesingle parts 70 of Fig. 7 towards the interiorhole body crosspiece 76 that makes progress, incomposite set 110 towards downwards.It should further be appreciated that the barrier film that preamble mentions is not shown in Figure 7.It should further be appreciated that in the view of composite set of Fig. 7 and the main body of not shown breathing mask, or its each several part, its certainly should-at least partially-in being clipped in hole body and outer hole body partly between.

Fig. 8 provides another view of venthole device, wherein also shows barrier film 120.As shown in previous drawings,interior hole body 70 is connected toouter hole body 84, is connected to frenulum then releasedly and connects secure component 100.As mentioned above, in barrier film is connected to the part of hole body with since user exhale to membranous inner surface exert pressure/membranous some part is moved freely during active force.And, as mentioned above, the edge of hole body in barrier film is attracted to when user is air-breathing, thereby blocking-up or stop air-flow inwardly to enter space between breathing mask body inner surface and the user face when user is air-breathing.

Usually Fig. 7 and parts shown in Figure 8 are by the materials such as plastics of substantially rigid, metal, and similar material is made.

In some scheme of the present invention, be formed as near the breathing mask body rim of wearer's eyes and be convenient to the wearer and select to use protective eye lens.And one or more schemes of the present invention also include the parts that help captivation or help the part of any routine or special protective eye lens is connected to the breathing mask part.For example, some part at the breathing mask edge of close wearer's eyes can comprise magnet, adhesive, and perhaps other are fit to engage releasedly mechanical fastening systems of at least a portion protective eye lens.In some scheme of the present invention, protective eye lens is connected to the main body of breathing mask by one.

Should note in some scheme of the present invention, certain material is by at least a portion setting around the breathing mask body surfaces, it towards wearer's skin (for example inwardly is fit to, comfortable encapsulant is the water-setting material for example, foamed materials, or the similar material that (at breathing mask/wearer's seam) adds around the breathing mask edge; Perhaps improve the tacky sealant of edge sealing and breathing mask performance).

In some scheme of the present invention, breathing mask, frenulum, perhaps add in the miscellaneous part and be applicable to and detect or measure some variable, elapsed time for example perhaps is inhaled into or the air of breathing out or the cumulant of gas componant, or temperature, or humidity, or some other this class variable, the perhaps pick off of its some combination; And for example computer or wearer or other such signal recipients provide signal to give massaging device immediately.Signal can be sense of touch, vision, sound, olfactory sensation, or the signal of some other sensory effects.Pick off can be as the simple things of the decolored indicator that is connected to breathing mask or frenulum with signal.Perhaps pick off can be operated and be connected to another and can receive, and storage is handled, show and the device of transmission information-no matter this device is connected to or is independent of breathing mask.
