Description
DESCRIPTION OF PREFERRED EMBODIMENTS
[0080] In the following description of preferred embodiments of the present invention, identical reference signs denote identical or comparable components.
[0081] FIG. 1: State of the art: eye protection at the top of the surgical mask.
[0082] FIG. 1a shows a schematic sketch of the side view of the head 1 of the wearer of the mouth-nose guard 10 with eyes 2, ears 3, nose 4, mouth 5 and chin 6. Mouth 5 and nose 4 are covered by a mouth-nose guard 10 acting more or less well as a filter. FIG. 1b. shows the arrangement from above. The material 11 is usually a fabric, preferably multilayered. Individual adaptation to the shape of the face is usually provided by fold structures 12, and there are many variants on the market in this respect, including those with a stable frame and with adaptable deformation elements. The known mouth-nose guard optionally has a connection area at the top to an eye shield 20, connected via connecting area 23. The protection of the eye shield 20 can partially cover the forehead and have a curvature 22 that follows the forehead. The material 21 is transparent at least in the eye area 2, circumferential non-transparent edges are possible, as well as further connecting areas for connection to head hoods, etc. Despite all these details, this arrangement has serious hygienic shortcomings, because it splashes unhindered on the mouthguard. Likewise, the wearer can touch this mouthguard unhindered, which often happens unknowingly. This happens because the mouthguard is not covered but openly accessible. Since the mouthguard is usually moist, it represents a breeding ground for germs. In addition, in the event of rapid air movements, for example when coughing or speaking, the mouth-nose guard 10 can emit aerosol contamination that can affect the patient. This risk of contamination must be prevented in particular. Thus, the mask 10 basically has a filter area 11 that can be contaminated by splashes and/or aerosols. The pull strap or elastic band 15 holds the mouth-nose guard 10 to the ears 3, the protection can rest on the front of the nose 4, wherein, again, there is a risk of contamination that can be transferred to the patient. The protective shield 20 optionally added above is quite close-fitting or also inclined forward, with seam 23. The material 21 of the eye protection 20 is usually colorless transparent. Characteristic for the group of these variants is that the breathing air can flow to the patient during exhalation. This also applies to the variants with lateral blow-out valves in particular, as they are used especially for protection against chemicals, these have a high protection class for the wearer but a poor protective effect for the opposite or the patient. This is because contaminated material and possibly liquid collects at the blow-off valve due to condensation and is then ejected as drops or aerosols.
[0083] FIG. 1a shows the prior art with a textile mouth-nose guard 10 and an eye shield 20 coupled to the top, but leaving the mouth-nose area exposed. The consequence is the danger of contaminating the filter area 11, 12, by touch and by splashes. The nose 4 is covered by the filter element or by textile or by other materials, the mouth 5 as well and in the vast majority of embodiments also the chin 6. The disadvantages are described above. The air 8 flowing out through the filter can reach the patient directly and contaminate him by aerosol.
[0084] FIG. 1b shows the same arrangement systematically from above. One can see the joint 23 where the eye shield is coupled to the mouth-nose guard 10. The filter fabric 11 lies openly unprotected. The eyes 2 are covered by the splash guard. Both together are held by the rubber bands 15, which hold preferably to the ears.
[0085] The unhindered transfer of contaminated air or droplets between the wearer and the patient poses an unreasonable risk to the patient in many FFP3 masks used by dentists. Most of the time, this major risk is not discussed, but for the containment of spreading infectious diseases, it is very important to at least reduce the contamination load for both parties involved, the mask wearer and the patient on both sides.
[0086] FIG. 2: Protective shield clamped to the side of the mouth-nose guard
[0087] FIG. 2a shows a side view of the head of the wearer 1 with the mouth-nose guard 10 attached and with the protective shield 30 attached to it. FIG. 2b shows the constellation from above. The protective shield 30 is preferably a visor extending from under the chin to above the eyebrows. The material is waterproof and transparent at least in the field of view of the eyes, preferably also in the other areas. It may be a thin film of polycarbonate or of acetate or of some other material that is sufficiently optically transparent not to interfere with the wearer's view. The film may also be coated, particularly to reduce reflections and to prevent fogging caused by condensing moisture from the breathing air. The protective shield 30 with its coupling devices 34, 36 is mechanically coupled to the mouth-nose guard 10 directly via coupling elements 14 and 16 or indirectly via spacer elements so that its relative position and spatial orientation relative to the head of the wearer is largely fixed. The necessary holding force for the mouth-nose guard 10 is thus increased, depending on the weight and design of the mouth-nose guard and the protective shield, and in particular also on the distance of the shield from the face. If necessary, further holding points can be introduced between the protective shield and the head, which are not shown here in FIGS. 2a and 2b. Shown schematically is the holding of the mouth-nose guard 10 by partially elastic loops 15, which are guided around the ears 3. The attachment point of the holding device 15 can coincide with the coupling points 14, 16 for the shield or be designed separately. It is characteristic that the entire mouth-nose area and thus also the mouth-nose guard 10 is covered. Contamination of the filter element 11 is thus prevented. In addition, the flow of the outflowing breathing air 9 is deflected, and in particular, in the example of use by a dentist, it no longer hits the patient directly when exhaling or coughing. Optionally, the mouth-nose guard carries an adaptation element 17 for sealing adaptation, in particular to the individual contour in the nose area, in order to prevent the moist breathing air from escaping there in the direction of the eyes, in particular also to prevent fogging of glasses lenses and self-contamination of the eyes. This simplified arrangement avoids touching of the mouth-nose mask and the face. In addition, splashes coming from the patient are intercepted and the transfer of contaminated exhaled air directly to the patient during coughing or when the exhalation valves open is prevented.
[0088] FIG. 2a shows a preferred embodiment of the protective shield 30 with a shell shape drawn backwards towards the neck at the chin, which may be necessary to prevent splash contamination from below, e.g. for dental use by the dentist. Conversely, this shape of the splash guard 30 also deflects the outflowing respiratory air schematically following the arrows 9 and does not flow directly to the patient. This protects the patient from contamination. Coupling elements 14, 16 on the mask correspond with spacing elements 34, 36 on the shield 30 to provide a spacing of the shield from the cheeks at the side of the face. The mask 10, to which the shield 30 is attached, is fastened to the ears 3 or to the head 1 of the wearer. Preferably with partially elastic band elements 15. FIG. 2b shows the shield 30 attached to the mouth-nose guard 10 from above, analogous to FIG. 1a. The mouth-nose mask 10 itself is fastened to the head with sufficiently stable tension straps, e.g. leading backwards above and below the ears, preferably also with partially elastic tension straps with surface adhesion, which can be easily fixed to the back of the head. The attachment of the straps 15 to the ears 3 is only one of the possibilities and in many cases permanently not sufficiently stable, but for very light arrangements without further attachment elements at the shield 30 quite functional. The protective shield 30 may have a shell-shaped form as shown, but it may also be shaped like the lateral surface of a cylinder (see FIGS. 4a and 4b) or include beveled flat areas.
[0089] FIG. 2c shows an embodiment of the protective shield 30 with coupling elements 34, 36, which are used for coupling to the coupling elements 14,16 on the mouth-nose guard. Due to the ellipsoidal curvature in two spatial directions, the shield in this embodiment has a comparatively spatially stable shape of its own even without the coupling. For an alternative embodiment of the shield 30 without a shell shape, the curvature requires attachment in at least two locations, such as three locations on a glasses frame, front and left and right sides, or on the mask. see FIG. 4a and FIG. 5a.
[0090] FIG. 3: Fastening the protective shield with central clamping piece
[0091] FIG. 3a shows a further embodiment in simplified schematic representation in side view. FIGS. 3b and 3c show the constellation in top view. The protective shield 30 or visor, respectively, is here attached to a central coupling element 47 on the breathing mask 40, which is mechanically stable at least in this area. The mouth-nose guard 40 here has more the form of a respiratory mask with preferably replaceable filter element 41, which can preferably be reached from the outside for filter replacement, preferably without having to remove the mask.
[0092] This mouth-nose guard 40 comprises an individually adaptable sealing area 46, which fits circumferentially around the mouth and nose as completely and as tightly as required by the protection classes, e.g. for a tightness of at least 95% for FFP3 masks. The sealing area is designed in terms of material selection and material thickness so that it can fit against the wearer's face without undue stress on the wearer in order to achieve sufficient tightness. For this purpose, the tension elements 15 must provide sufficient force, although this can usually no longer be achieved by ear fastening. The shape of the mask 40 may have been determined on the basis of individual 3D data of the head 1 of the wearer, thus having an individual fit. In particular, the sealing area 46 also extends over the nose 4 and under the eyes 2. Flexible elements may be attached at points of low elasticity, for example foam elements or sealing lips. The material of the protective shield is sufficiently stable, at least in the coupling area 37, to transmit a holding force to the protective shield 30. Preferably, there is an aperture 37 in the shield 30, with a diameter of preferably at least 10 mm, particularly preferably at least 20 mm. An adapter piece leads through this aperture 37 of the shield 30, which can create a clamping effect and sealing effect between the mask 40 and the shield 30. In the vicinity of the lead-through or directly as part of the lead-through, preferably mechanical keying elements are provided which create a spatial orientation between mask 40 and shield 30. Alternatively, in the vicinity of the opening 37, the shield 30 is held and fixed in its orientation solely by the frictional force on the clamping element 47. Distally beyond the shield 30, the filter element 41 can be connected to the breathing air path of the mask 40. Preferably, different filter variants are available for this purpose, which can be coupled to the adapter 47. The mask 40 can also be used without the protective shield 30, but then with increased bidirectional contamination risk. This mask 40 also has at least two fastening elements 44, 46 which correspond to coupling elements 34, 36 on the shield and which can be reversibly connected and disconnected again.
[0093] In particular embodiments, the connection between the shield 30 and the mask 40 or mouth-nose guard 10 is not reversible but permanent.
[0094] In another embodiment, fastening elements that are located laterally (see FIGS. 2a and 2b) are combined with fastening elements that are located centrally at the front (see FIGS. 3a, 3b and 3c). This results in increased stability and load capacity of the coupling of the shield 30.
[0095] In addition, the protective shield can also be supported in the upper head area, e.g. by coupling it to glasses or by means of a forehead support. This serves in particular to stabilize the upper shield area in the event that a lamp, camera or other accessories are to be clamped to the shield 30.
[0096] FIG. 3a shows another way of attaching the shield 30, now to a more mechanically stable breathing mask 40 with a flanged replaceable filter element 41. The mouth-nose mask portion 46 is preferably shaped to fit individually. The holding force on the head positions the mask securely around the mouth and nose to achieve the required tightness. Air exiting through the filter 41 can reach the patient, but is filtered. Attachment to the head is via the retaining points 44.
[0097] FIGS. 3b and 3c show the mask 40 from above and the shield 30 attached to the mask 40. Here again with a curvature. One can see the guidance of the inhaled air through an aperture 37 into the mouth and nose, and out through the filter again if required. Next to this is a relief valve 49, see FIG. 3c, through which air can escape when coughing, etc. This escaping air flow 9 is deflected by the shield 30 and cannot reach the patient directly. However, there may also be valves or additional filter paths for exhalation, in which case the exhaled air is deflected by the shield similar to FIG. 2b.
[0098] FIG. 4: Shield attached to mouth-nose guard with internal replaceable filter
[0099] FIG. 4a shows a side view of another embodiment of the shield in combination with another embodiment of a mouth-nose guard 10. FIG. 4b shows the constellation and the air path from above. Here, the shield 30 is predominantly curved in only one spatial direction, i.e., it is predominantly in the form of a section of a lateral surface of a cylinder. The cylindrical curvature of the shield results here from the interaction of several holding points 34 laterally above, 36 laterally below and 38 centrally in front. These correspond to the coupling elements 14, 16 on the mask 10. The optional spacers on the right, left and front create the distance of the shield from the mask and face. The airway does not pass through the shield here, and the aperture 37 in the shield is not present. The mask includes replaceable filters 19 and a permeable filter cover 18. The sealing rim may be circumferential with sealing lip or foam elements, or may be customizable. The filter 18, 19 is located on the side of the mouth relative to the shield. Thus, both the flow of the inhaled air is guided by the shield and the flow of the air 9 exiting through these filter elements 19 and the cover 18. The coupling of the shield 30 takes place via coupling elements which are preferably located in the mechanically more stable area of the mask 10, which can have the function of a predominantly dimensionally stable three-dimensional frame 13, which also supports the cover 18 of the filter element 19. Here, too, different filter elements can be used depending on the requirements. This frame is pulled backward against the face by the strap attachment 15, providing stability to the mask relative to the head. The shield 30 is optionally shell-shaped or cylindrical in shape and is attached to the mask or to the mouth-nose guard 10, respectively.
[0100] FIG. 5: Shield clamped to frame and lamp
[0101] FIG. 5a shows a schematically sketched protective shield 30 with predominantly sole attachment not to the mouth-nose guard but to a glasses frame 50, e.g. a pair of magnifying glasses, preferably in the area between the eyebrows. In this embodiment, the magnifying optics 51 are attached to the glasses lenses or to the frame 52. The transparent protective shield 30 made of material 31 has a lateral edge 32 and may have rectangular or also rounded contours, have beveled flat areas and have cylindrical or ellipsoidal curvatures. The shield is attached for stabilization firstly centrally above the nose to the glasses temple 53 and laterally to the ear temples, preferably by inserting the glasses temples 53 through holes 37 in the shield 30, or by fastening elements 57 on the glasses temple holding the shield at lateral attachment points 37. The magnifying optics 51 require a forward spacing of the shield 30, which is preferably achieved by spacing elements 60. According to the invention, the fastening element clamping the shield 30 has at least a first clamping element 73 and a second clamping element 62. The spacer 60 is also self-holdingly fastened to the glasses frame 52, the clamping elements 57 and 61 cooperating here. Preferably, these are magnetically acting clamping elements. The length of the spacer 60 depends on the space requirement of the loupe optics 51.
[0102] FIG. 5b shows the arrangement of the elements on the magnetic clamp with spacer 60 in enlarged detail. The first clamping element 73 generates the clamping force together with the second clamping element 62. The spacer is held to the frame 52 of the glasses 50 via the clamping elements 61, 58.
[0103] FIG. 5c shows the constellation of the shield with magnifying glasses with lamp from above. Several auxiliary devices such as lamps 70 or cameras can also be arranged.
[0104] FIG. 5d shows a perspective view of a protective shield with attachment to magnifying glasses via clamping elements and spacer 60. Attachment of lamp 70 is optional, and the lamp can be replaced by an end piece (not shown). The protective shield 30 can also be attached to the mouth-nose guard (not shown).
[0105] FIG. 5e schematically shows a rotationally stable clamp attachment with two parallel magnetic clamping elements 58 in the clamp part 56 on the glasses side. Likewise, two magnetic clamping elements 62 in the spacer 60 and, in addition, an end cap 80 with clamping elements 82 to develop the clamping force for the shield 30. The end piece 80 can be replaced by a lamp or camera 70, with clamping elements 72, 73.
[0106] FIG. 6: Visor-magnet clamp for lamp/camera
[0107] FIG. 6a shows the clamping device with clamping cap 80 and clamping elements 82, 73 for clamping accessories such as lamps 70 or cameras. The clamping is done by means of static friction and/or mechanical keying directly to the shield 30. This allows the attachment of such accessories without the need for a glasses frame (compare FIG. 5a). The clamped equipment 70, in the example a micro LED battery light, is very light and can be removed if necessary. The weight is preferably between 5 and 50 grams, between 5 and 20 grams for embodiments without a battery with an external power source, and between 10 and 30 grams for embodiments with an integrated battery. In the embodiment shown without attachment to head frame or glasses, the accessory 70 is clamped via the first clamping element 72, 73 and a second clamping element 80, 82. The foil or pane 31 of the protective shield 30 is so thin or so widely perforated in the clamping area that the clamping effect is largely sufficient for stable fixation of the protective shield.
[0108] With modern magnetic elements 82 and 73, which can be identically oriented cylinder magnets, forces are achieved so that even foils up to 1 mm thick can be clamped. The smaller the gap filled by the shield between the clamping elements 82, 73, the greater the clamping force with the same magnets. Supporting and for better orientation of the shield 30, further orientation elements can be attached to the devices or elements 70, 60, 80, 50, which scramble with orientation elements on the protective shield.
[0109] FIG. 6b shows an attachment of an LED light 70 to the shield 30 by means of the clamping device 72, 73, 82, 80. In addition, a support part 85 may be attached, in particular for supporting the lamp on the forehead.
[0110] FIG. 7: Shield with coupling elements for attachment to head-mounted device
[0111] FIG. 7a shows a protective shield 30 made of preferably transparent material 31 and with fastening elements 37 in the form of holes for the passage of glasses frames on the right and left and with further fastening elements 34, 36 for coupling to a mouth-nose guard or to a breathing mask equipped with coupling elements 14, 16. At the top center, one can see an opening for strongly clamping magnetic holders or other fastening elements for clamping the shield to a glasses frame with the aid of a spacer.
[0112] FIG. 7b shows a preferred embodiment of the protective shield 30 without glasses attachment with attachment via the coupling elements 34, 36 to a mask (not shown) equipped with corresponding elements therefor. Plug-in elements, magnetic elements, Velcro elements and/or other coupling elements can be used for fastening.
[0113] FIG. 7c shows a shield 30 with coupling elements in the upper area prepared for coupling to glasses, without additional coupling to a mask. The particularly preferred embodiment comprises at least one fastening element 37 on the right and left side, respectively, for contact with the ear temples 53. Furthermore, at least one centrally arranged coupling element 56 for attaching a counter-clamping element 60 or 80 or 70, so that the pane of the protective shield is clamped at this point. Furthermore, holding elements may be attached which correspond to holding elements 57 on the glasses temples (not shown. See FIG. 5a).
[0114] The mechanical stability of the shield 30 at the clamping point is achieved by an at least one-dimensional curvature. Depending on the application, one-dimensional curved shields like in FIG. 4 and FIG. 5 or two-dimensional curved shields like in FIGS. 2 and 3 as well as FIG. 6b are suitable.
[0115] FIG. 8: Shield for protection against laser radiation
[0116] FIGS. 8a and 8b show a shield 30 for protection against laser radiation in various views. The shield 30 includes a curved main section 30A, a lower protection section 30B, and an upper protection section 30D. The main section 30A is in the shape of a segment of a lateral surface of a cylinder and is designed to cover the eyes of the wearer. The lower and upper protection sections 30B, 30D extend transversely or perpendicularly, respectively, to the main section 30A. The protection sections 30B, 30D are configured to be positioned below and above the eyes, respectively, and to be brought close to the face of the wearer.
[0117] This is to attenuate or prevent laser radiation coming from below or above from entering the eyes. The lower protection section 30B has a recess 30C for the wearer's nose.
[0118] The shield 30 is made of acrylic in the main section 30A and/or in the protection sections 30B, 30D, for example, and has a thickness of about 3.2 mm there.
[0119] Further, the shield 30 includes coupling elements 37 in the form of hooks. The hooks 37 are disposed on the main portion 30A on an inner side of the shield 30, that is, on the side facing the wearer. The hooks 37 can be hooked into temples of a glasses frame so that the shield 30 is carried by the glasses.
[0120] In addition, apertures 35 are provided in the shield 30 centrally in the main section 30A, i.e. in the area above the nose of the wearer. Magnets 63 are bonded into these. The magnets 63 are provided to interact with magnets 82 of an end cap 80 and magnets 62 of a spacer 60 to clamp the shield 30 between the end cap 80 and the spacer 60. The spacer 60 has further magnets 61 at an end remote from the shield 30, which are arranged to interact with magnets of, for example, a glasses frame. Thus, the shield 30 can be attached to glasses via the magnets and the spacer 60 in addition to the hooks 37.
[0121] This patent application claims the priority of German patent application DE 10 2020 112 737.5, the disclosure content of which is hereby incorporated by reference.
