Disclosed embodiment can be about respirator facepieces, and it is with the pad around its outer rim location.Mask body can seal the mouth, nose of user or the two, and mask body is usually designed to and filters the air that becomes a mandarin.The material of mask body itself can be fulfiled this filtering function, if or mask be impermeable, can use strainer valve (for example, possibly, the two-way valve that filters air amount and allow exhalation air to be discharged from).In certain embodiments, even, in the time that mask body provides the filtration to the air amount that becomes a mandarin, single-pass outlet valve can be used, to improve expiration.Described pad is generally used for improving the sealing between face and the mask body (outer rim) of user, closes thereby provide to be close to.For example, only there being pad to provide and be close to (, in the time that mask is fixed to the face of user by band) in the embodiment closing, mask can not comprise nose folder (because nose folder to provide be close to incompatible say optional).But, in other embodiments, mask can comprise nose folder and pad, so that better laminating to be provided.In certain embodiments, pad can be self-adjustable pad, automatically the fit face contour (for example, pattern/somatometry) of user of this pad.In certain embodiments, pad is filled with fluid, makes the face of its user of easily fitting.The conformal performance of pad often allows this pad to be filled in the gap of (between the operating period of mask) between mask body and the face of user, allows mask to be used to vast user group thereby provide to be close to merge to the concrete face contour of specific user.In certain embodiments, the conformal performance of mask can be consistent, and when band mask is fixed to user on the face time applied pressure can allow direction of flow in pad between mask and face, may have the region (being applied to the region of pad because these gaps can be pressure/power still less) in gap, and expand to fill described gap in these regions.In a further embodiment, the conformal performance of pad can position-based and change, that wherein pads during use (for example may run into gap, the recess of the face of user) part often more conformal, and the part of the ledge of the face that may run into user of this pad is often so not conformal during use.In certain embodiments, pad can be (hollow) pipe (thereby conventionally connecting around the outer rim of mask body in ring-type mode) single, one.In other embodiments, pad can comprise the independent fragment of a series of line styles, and wherein the fragment of each sealing is as the independent pad (whole fragments can be provided together around the padded coaming of the whole outer rim of mask) of a part for the outer rim of mask.

Face has complicated pattern.For example, face can comprise outstanding (or protruding) for example bridge of the nose of part and jaw line likely.Face also can comprise recess, for example transition portion from the wing of nose to cheek part (and likely cheek part).The 3 dimensional coil geometry that the nasal area of face is especially complicated, wherein the transition portion from the wing of nose to cheek is especially difficult to effectively seal.Consider the complicated three-dimensional nature of each face, and extensive variation (that is, crowd changes) in face contour in whole user population, being difficult to provides effective sealing to respiratory mask.Embodiment attempts to use with the pad of enough conformal performances (being normally filled with fluid) and allows being close between mask body and the face of user to close.Embodiment automatically regulates, and wherein pads the conformal face contour with laminating user and closes (conventionally completely the band applied force/pressure of correct position on the face based on mask being fixed to user) with conformal being close to.

Fig. 1 shows the embodiment of respirator facepieces, it has mask body 10(or face component), nose and mouth that it filters air amount and has surrounded user between respiratory period, the pad 20(locating round the outer rim of mask body 10 makes described pad around this outer rim), and be with 15 for the one or more of face that mask body 10 are fixed to user.In certain embodiments, mask body 10 also comprises exhalation valve 11.Mask body 10 can be flexible (non-rigid) at some embodiment, thereby allows mask body 10 to meet better the face contour of user.For example, in the embodiment in figure 1, mask body 10 can be made up of filtration fabrics (for example,, as used in dust mask and/or surgical operation mask).The pad 20 of Fig. 1 is filled with fluid, makes it can be conformal.In certain embodiments, fluid can be air or certain other gas.In certain embodiments, fluid can be liquid, if if preferably it contacts with human body skin and/or is safe liquid when it is swallowed by people.In certain embodiments, this fluid can be gel (for example, the fluid of suitable thickness).In certain embodiments, whole pad is filled by single fluid, and in other embodiments, the different piece of pad can be filled with different fluid (this conformal performance that for example depends on the each part to this pad requires).The pad 20 of Fig. 1 is attached to the outer rim of mask body 10, makes in the time that respirator facepieces is used (for example, by being fixed to user on the face with 15), and pad 20 can contribute to provide to be close to close.In the embodiment in figure 1, pad 20 can for example, for example, by the one or more mask bodies 10 that are attached in several possible attachment means, ultra-sonic welded, binding agent, insert molding and/or hook and ring material (, Velcro.TM).

Fig. 2 illustrates the embodiment of the pad of Fig. 1.The pad 20 of Fig. 2 be pipe, its formed the outer rim of approximate mask body 10 sealing, tubular shape.Fig. 3 shows the cross section of the pad 20 of the Fig. 2 intercepting as shown.As shown in Figure 3, pad 20 is shells of hollow pipe or bendable material.Conventionally, fluid has filled up the inside of padding 20, makes to pad 20 and expands to provide conformal performance and/or buffering.Pad 20 diameter ranges that can have are from about 1mm to about 30mm.For example, can have the diameter of about 1mm-5mm, and reusable mask can have larger pad for the pad of disposable mask, its diameter is for example about 30mm to the maximum.Pad for example can be formed by rubber, polypropylene, PVC or nylon, and the scope of the thickness of the material of formation pad can be from about 0.3-0.8mm.The pad 20 of Fig. 2 can be made up of elastomeric material, for example rubber or nylon fabrics.In an embodiment, the material of pad is enough obedient to (for example, flexible and/or elasticity), make its can be in the time that pressure be applied on it (conventionally mask be fixed to user on the face time applied by band) distortion or distortion (for example, knuckle).Conventionally, band applies normal pressure with by position mask and the sealing of effective pad is provided, and wherein band applies the pressure (with being held in place on the face at user by mask cosily) that is less than approximately 5 bar conventionally.One or more coating materials that also can be coated with in the surface of pad 20.For example, if nylon fabrics or other non-airtight material are used to pad, pad so 20 inner surface and can be coated with sealant (for example, rubber) to seal described pad and to make described cushion steam close (or sealing is for filling seepage or the leakage of particular fluid of described pad).In other words,, if pad 20 material is not to be enough to impermeablely, so enough the coating of impermeable material can be applied to one or more surfaces of pad 20.In the embodiment in figure 1, pad 20 available stream volume expansions are to approximately 1 bar or more pressure, conventionally in the scope of about 1-5 bar (before mask is applied to the face of user).Fig. 4 A and 4B illustrate how knuckle is to be filled in the gap between mask body 10 and the face of user in some regions padding 20 between the operating period of mask.Fig. 4 A shows the mask before mask is applied to the face of user, has illustrated that pad 20 is in deformation state not.Fig. 4 B shows pad 20 and may be out of shape when mask for example, is fixed to the face of user by (, by with 15), in the outside knuckle in some region to be filled in the gap between face and the mask body 10 of user.In other words, Fig. 4 B has illustrated during use how the conformal performance of pad closes for providing to be close in the time that mask is applied to the face of user.In Fig. 4 B, pad positive knuckle to meet the wing of nose part of face of for example user.

Fig. 5 has illustrated with the embodiment of the respirator facepieces of pad (illustrate individually, but in use pad the outer rim that can conventionally be applied to mask body).Mask body 10 has outer rim 18, and it is designed to seal mouth and the nose of user.The mask of figure also has valve 12(, and it can be exhalation valve), and be one or morely with 15, these bands can be used for mask body 10 to be fixed to the face (and also providing enough power or pressure to form effective sealing) of user.For example, in use, pad 20 will close to form be close between the face at user and the outer rim 18 of mask body the outer rim 18(that pad 20 can be used for being attached to mask body).In the embodiment of Fig. 5, pad 20 is formed by single, integral tube, and this pipe has conformal performance feature consistent in whole pipe (along its length/girth).For example, the pad 20 of Fig. 5 can have consistent (cross section) diameter, consistent material or elasticity, consistent material thickness (in the wall of pad pipe), and/or consistent expansion (for example, the fluid pressure in pad pipe).This structure allows the fluidic response in pad 20 freely on whole pad 20, to flow in the power/pressure acting on pad.And, the material that forms pad 20 is enough obedient to (flexible/elasticity, for example) make to pad 20 can under pressure, be out of shape with outwards sufficiently knuckle so that any gap between face and the mask body 10 of user (it is enough conformal to provide being close between mask body 10 and the face of user to close making to pad 20, although mask body 10 is not to customize (but the extensively facial All-Service Mask that is designed to fit) for the face contour of concrete user) to be provided.In use, mask body 10 can be by with 15 faces that are fixed to user.Be with 15 therefore can apply power/pressure on mask body and/or pad.By being applied to the power of pad on 20 or the amount of pressure can change with position with 15, it is mainly the face contour based on user, pad contact user face outstanding (for example, protruding) part part experience more power/pressure, and part in gap between the face and the mask that are located at user of pad (conventionally, in the convex domain of the face of user) experience power/pressure still less.Pad high-tensile strength/pressure span of 20, by compressed, forces fluid to flow into the low power/pressure span of pad 20 from these regions, thereby makes thus those part swelling or knuckle provide to be close to and close to be filled in gap between face and the mask body of user.By this way, the pad 20 of Fig. 1 can provide automatic spacer sealing, can be used for optimizing laminating.

Fig. 6 A and Fig. 6 B have illustrated another exemplary embodiment of respiratory mask.In this modification, pad 20 has formed single, one (fluid filled) pipe, and this circumference of cannon bone, around the outer rim of mask body 10, allows the fluid stream (, on its whole length/girth) on whole pad.But the pad 20 of the embodiment of Fig. 6 A for example can have, along the conformal performance feature of the variation of its length (, depending on the face contour being associated with general user facial appearance).For example, in certain embodiments, the how conformal part of pad can be corresponding to the cheekbone of mask (or face of user), the bridge of the nose and/or menton part, and the side face part that conformal part still less can corresponding mask (or face of user).In certain embodiments, pad 20 can be to have in advance fluctuating, makes its shape can initially be prepared the recessed region that gap may appear in filling.And the pad in advance with fluctuating can be also changes aspect conformal performance, makes in use, fluid stream will further make part knuckle or the distortion relevant to the recessed region of the face of user.For example, pad 20 can be so not conformal in the part of the ledge of the face of the expection contact user of pad, and pad 20 part can be more conformal for example, to be filled in the part (part, being associated with the recess of the face of user) in the gap between face and the mask body 10 of user as the expection of this pad.Pad 20(or its part) can to use one or more in following technology to be manufactured into more conformal, for example: the larger diameter of pad, form the more thin material of pad, and/or for the elasticity more of described pad or the material of being obedient to.Similarly, pad 20(or its part) can to use one or more in following technology to be manufactured into so not conformal, for example: the more minor diameter of pad (for example, amount that may be based on being applied to the coating in the part of pad), form the more thick material of this pad, and/or for the still less elasticity of this pad or the material of compliance.In Fig. 6 A, for example, pad 20 is designed to the part more conformal (, the part of the wing of nose of the user of expection contact during use) of locating in the wing of nose part 23 along mask body, and the part of locating in the bridge of the nose part 22 along mask body is so not conformal).In certain embodiments, during can having, the part that the jaw line part 25 along mask body of pad is located arrives low conformal performance.And during can having, the part that in certain embodiments, the cheek part 24 along mask body of pad is located arrives high conformal performance.Fig. 6 A has illustrated original shape or the distortion (due to the different conformal performance feature of the different piece along mask body or position) of padding 20, and Fig. 6 B has illustrated and pads and 20 can further be out of shape to provide in the time that mask is fixed to (conventionally by be with) on the face of user and be more close to and close the mode of (by being filled in the gap between face and the mask body of user, for example, in recessed wing of nose part).As shown in Figure 6B, when being with 15 to apply power/pressure on pad 20 time, fluid in pad flows and leaves high-tensile strength/pressure portion (for example, bridge of the nose part) and flow to low power/pressure portion (for example, wing of nose part).By this way, pad 20 can automatically regulate self to be suitable for providing tighter laminating to concrete user, based on oneself face contour of this user.

Fig. 7 A and 7B have illustrated another embodiment of respirator facepieces.The mask of Fig. 7 A and 7B has mask body 10 and is attached to the pad 20 of the outer rim 18 of mask body.The pad 20 of Fig. 7 A comprises the fragment 27 that array of fluid is filled, and these parts are connected in series with the outer rim around mask body.Each fragment 27 be sealing, the hollow pipe of fluid filled (normally pliable material), and fragment 27 is connected to form the tubular shape of the outer rim 18 around mask body of whole pad 20 end-to-end.This mode does not allow the fluid between the fragment 27 of pad 20 to flow (, do not move or flow as another fragment from the fluid of a fragment), but fragment 27 still can (for example affect each other more or less by laterally applying power/pressure, fluid in suppressive fragment can push away on sidewall and the fluid that brings some pressure to bear thus in adjacent low pressure fragment on, this can cause that the distortion of low pressure fragment or knuckle are to be filled in the gap between face and the mask body of user.Pad each fragment 27 of 20 can have its oneself conformal performance feature, for example, depend on the part of the face of its position and each fragment mask/user associated therewith.Conformal performance can be with one or more adjusting the in following technology, for example: the diameter that changes this fragment, change the amount of the fluid that makes this fragment expansion, change the thickness of the material that forms this pad section, and/or change elasticity or the compliance of the material that forms this pad section.Therefore, it is more conformal that certain fragment can be used one or more in following technology to be manufactured into, for example: larger diameter and/or the volume of this fragment, increase the fluid (pressure) that this fragment is expanded, form this fragment with thinner material, and/or realize this fragment with the material that has more elasticity or compliance.Similarly, it is so not conformal that this fragment can be used one or more in following technology to be manufactured into, for example: the less diameter of this fragment and/or volume are (for example, the amount of coating of a part that may be based on being applied to this fragment), reduce the amount of the fluid (pressure) that makes this fragment expansion, form the thicker material of this fragment, and/or for the still less elasticity of this fragment or the material of compliance.So for instance, the embodiment of pad section can have the diameter of scope from about 3-10mm, scope is from the fluid pressure of about 1.1-5 bar, and scope is from the cushion material thickness of about 0.3-0.8mm, and/or use has the material of elastic range from about 0.5-5 kilogram.In Fig. 7 A, for example, the fragment (that is, expection contacts the fragment of the wing of nose of user during use) that pad 20 is designed to locate in the wing of nose part 23 along mask body is more conformal, and the fragment of locating in the bridge of the nose part 22 along mask body is so not conformal.Fig. 7 A has illustrated and (has for example padded 20 initial (having in advance fluctuating) shape or distortion, due to the different conformal performance feature of the part position of the part along mask body), and Fig. 7 B has illustrated and pads and 20 can further be out of shape to provide in the time that mask is fixed to the face (conventionally by be with) of user and be more close to and close the mode of (by being filled in the gap between face and the mask body of user, for example, in recessed dilator naris office).

In certain embodiments, replace in manufacture process with other other pre-filled pad of air or certain, pad is alternately filled with chemical material, and these chemical materials can be triggered to react, and this chemical material are converted to gas so that pad expands.Conventionally, this chemical material can be liquid form before being triggered.For example, can or vibrate this material and trigger this chemical reaction by compression, mixing.For example, in one embodiment, one or more in chemical substance can be maintained in rupturable bag at first, thereby and this bag can be broken and trigger this reaction by pushing this part of described pad.In certain embodiments, the part part of described pad can by individually expand (or, keep not reacting and unaerated), thereby provide a kind of mode (because if only needs further make suitable demi-inflation close to form to be close to, user can trigger these parts so) that further makes to pad the concrete face contour that is applicable to user.

In formation, the respirator facepieces of Fig. 1 can be by being formed pad 20 outer rims 18 that are attached to mask body 10.One or morely be with 15 also can be attached to mask body or pad.Mask body 10 can be provided or form, and mask body 10 is by outer rim normally cup-shaped and that be designed to have mouth and the nose that can seal user.Mask body 10 can be formed by filtering material, or it can be formed but strainer valve is installed by impermeable material.Alternatively, mask body can be filtering material but exhalation valve is also installed.Forming in pad 20, the whole pad maybe part of this pad or the conformal performance feature of fragment can be selected (for example, the position of this part based on mask or fragment and/or the region by the face of the user of this fragment or part expection contact).Pad now can be formed and have selected conformal performance feature (this can change along with part or fragment at some embodiment).The formation of pad can comprise one or more in following: the formation of pipe, this pipe (by applying coating, for example), to the pressure of expecting or select, and is sealed to form the pad of fluid filled with this pipe of fluid filled in the surface that seals this pipe.In certain embodiments, the formation of pad also can or alternatively comprise the multiple fragments that form the vicissitudinous conformal performance of tool, by the each fragment of fluid filled, seals or seal each fragment, and/or the pad that the plurality of fragment is linked into an integrated entity.After pad is formed or provides, it can be attached to the outer rim of mask body.In certain embodiments, attachment means can be permanent, but in other embodiments, attachment means can be removable (make in the time that user changes mask, pad can be attached to the respirator facepieces body of new disposable (or limited use)).For example, pad can be by the one or more mask bodies that are attached in following: ultra-sonic welded, binding agent and/or Velcro.TM.

In use, the mask body 10 of Fig. 1 for example can be installed to user on the face to surround mouth, nose or the two.The most normally, embodiment surrounds mouth and the nose of user.With 16 faces that can be used to mask body 10 to be fixed to user.While doing like this, pad 20 automatically meets the concrete face contour of specific user, and distortion (for example knuckle) is to be filled in the gap between the outer rim of mask body 10 and the face of user.This provides to be close to respirator facepieces and has closed.In certain embodiments, user (for example can also be adjusted in nose on the mask body folder bridge of the nose part of mask body (conventionally across), deformable material strips, the shape after but it can keep it to be out of shape by hands is moulding fully is during use to meet the face of user), but in many examples, pad 20 itself provides enough conformal performances to close to provide to be close in the situation that not needing nose folder.During use with 15 be applied to the pressure of pad on 20 can be automatically to pad 20(based on conformal performance) the moulding concrete face contour with the specific user of fitting.By this way, embodiment can provide the laminating of improvement to respiratory mask, and has simplified occupation mode (by eliminating the needs to manual adjusting range tool body, for example, using nose folder).It will be appreciated by those skilled in the art that these and other the purposes of embodiment.
