Technical Field

The invention relates to the technical field of medical instruments, in particular to an external ear matching type protection device and a mask.

Background

After the respiratory infectious epidemic (such as the novel coronavirus pneumonia which is initially outbreak at 2020), the mask is used as a protective article, and can effectively prevent viruses, dust and the like from entering respiratory tract, lung and the like through mouth and nose. The mask plays an important role in individual protection. The mask mainly comprises a covering mask body for covering most part of the area below the eyes of a human body and mask ear ropes for relatively fixing the mask body on the face of the human body. A large amount of medical care and disease control personnel put into the front line of fighting against epidemic situation and spreading and fight, and medical care and disease control personnel need wear gauze mask, goggles etc. for a long time at the during operation and satisfy the protective articles that the isolated system required, cause the performance of many medical care and disease control personnel ear department etc. many places oppressive injury to appear, if strangle the trace, red swelling, ear root crush injury, ear loss of consciousness etc.. For this reason, it is necessary to protect the ears of a person who wears a mask for a long period of time.

For example, chinese patent publication No. CN205462695U discloses a mask with ear protection structure. The ear protection cushion comprises a rectangular cover body, a mask ear rope and an ear protection cushion, wherein the ear protection cushion comprises a cushion body and a pressing rope layer fixed on the cushion body, a connecting hole in sliding fit with the mask ear rope is formed between the pressing rope layer and the cushion body, the front end of the cushion body is integrally connected with a sticking cushion body, and a bonding layer is arranged on the sticking cushion body. The utility model discloses a take gauze mask of earflap structure, it is through setting up the earflap pad on gauze mask ear rope, the earflap pad can alleviate even eliminate the oppression of gauze mask ear rope to the ear, can avoid wearing the painful sense of ear that the gauze mask produced for a long time, can improve the gauze mask and wear the travelling comfort; and for the mask wearer with the glasses, the glasses hanging part can be adhered to the adhesive pad body through the adhesive layer, so that the problem that the glasses fall off can be effectively prevented. However, in the utility model, the adhesive layer is arranged to be fastened behind the ear, but some people have the problems of allergy to the adhesive layer and the like and cannot use the adhesive layer; and if the adhesive layer cushion body is not adopted, the cushion body cannot be kept and is easy to fall off.

Furthermore, on the one hand, due to the differences in understanding to the person skilled in the art; on the other hand, since the inventor has studied a lot of documents and patents when making the present invention, but the space is not limited to the details and contents listed in the above, however, the present invention is by no means free of the features of the prior art, but the present invention has been provided with all the features of the prior art, and the applicant reserves the right to increase the related prior art in the background.

Disclosure of Invention

Aiming at the defects of the prior art: the gauze mask ear rope of gauze mask tightens up the back for the face guard hugs closely at the cheek position, but gauze mask ear rope can make the ear back position receive great pressure load (this load roughly can be regarded as line load moreover), and after the wearing time is permanent, can locally appear reining in bad phenomena such as trace with the position of gauze mask ear rope contact. When wearing the gauze mask, because the ear belongs to the comparatively soft organ of human body, the ear receives great load simultaneously and causes it to produce the easy macroscopic displacement of soft body and be difficult for keeping in the ear to cause actions such as the gauze mask drops, and then cause the medical science of wearer to expose, especially the medical personnel in the isolation region, very easily cause its medical infection.

The invention discloses an external ear fitting type protection device, which can relatively fix a mask on the face of a wearer and comprises: soft body, its structure is for can laminating the ear of wearer, soft body's the back of the body ear body has along its longitudinal extension hold the groove, thereby the gauze mask ear rope can imbed hold the groove thereby make the gauze mask can soft body laminate in cover in the face of wearer under the condition of wearer's ear.

According to the present invention, the force applied to the supporting groove by the mask ear string can be applied to the region of the soft body where the root of the ear is located by the ear-attached body of the soft body, and the planar pressure is applied by the ear-attached body of the inequality ridge shape of the two wings in such a manner that the pressure in the middle region is greater than the pressures on the two wing sides and the pressure on the side close to the skull is greater than the pressure on the side far from the skull, as viewed in the cross section of the soft body, so that the reaction force applied to the root of the ear by the mask which is attached to the face of the wearer under pressure can be received by the root region of the ear in a three-dimensional manner. That is, in the present invention, the planar pressure is not applied on a single plane, but is applied in a planar manner to the root of the ear, which varies from person to person and in various forms, by the deformation of the soft body by the urging force after wearing the mask. "mask that fits the face of the wearer under pressure" is necessary for wearing a mask such as N95. The planar compression on the face caused by wearing the mask for a long time can leave deep impressions, and the compression on the root of the ear caused by higher pressure is not inconstant. The ear root must face a non-trivial challenge given that the ear also needs to withstand the pressure of the visor. The soft body of the invention disperses the planar pressure in a two-wing inequality ridge shape way behind the ear, especially on one side of the skull, so that the comfort and the safety of wearing for a long time are improved. In this case, the region of the soft body extending upwards can also, when subjected to protective goggles or the like, distribute pressure unevenly in a similar manner to the lateral wings, in particular with different pressures towards the side of the skull and away from the side of the skull, in particular by means of a structural design distributing a greater pressure towards the side of the skull.

According to a preferred mode of the invention, the lug body of the soft body is provided with a smooth convex body which is used for abutting against a connecting part between the ear and the skull and extends along the longitudinal direction of the lug body and is approximately parallel to the bearing groove, two sides of the smooth convex body are respectively connected to two side ends of the back lug body in a transverse extending mode through a first transition body and a second transition body which are different in curvature, and therefore the soft body can enable deformation of the smooth convex body to be relatively fixed by the ear, the skull and the connecting part based on pressure acting on the bearing groove. Such different curvatures can be designed according to physiological configurations for most human bodies, and since they are deformable, the curvature is widely applicable. However, it is preferred that the pressure is different toward the skull side than away from the skull side, in particular that a greater pressure is distributed toward the skull side by the structural design.

The first transition body and the second transition body have a fool-proof design concept: when wearing, because medical personnel are daily busy, the person of wearing can judge whether wear anti-with soft body based on travelling comfort and sense of touch for the person of wearing can in time discover whether wear anti-, prevents that it from in medical science practice process, causes medical science to expose because of soft body drops. Smooth convex body, first transition body and second transition body all can produce the deformation under the condition that pressure has been applyed by gauze mask ear rope in the bearing groove, smooth convex body is based on its deformation and is kept each other by the position of being connected between skull and the ear, first transition body is based on its deformation and keeps fixedly each other with the mutual laminating of skull, the second transition body is based on its deformation and keeps fixedly each other with the mutual laminating of ear, thereby soft body and skull, ear and its position of being connected reciprocal anchorage and keep, contact area has been increased, and the skull belongs to hard shape structure and non-deformable, make soft body be difficult for producing macroscopic displacement, and the position of being connected has limiting displacement, thereby make soft body be difficult for droing, and the risk that the person of wearing medical science exposes has been reduced.

The pressure generated by the ear rope of the existing mask is directly line load, so that the connecting part (ear root) between the ear back and the skull bears larger pressure, and the tightening mark and the pressing feeling are generated when the mask is used for a long time; in the invention, the pressure generated by the ear rope of the mask is absorbed by the deformed part of the soft body, and the smooth convex body can be in surface contact with the connecting part (ear root) between the back of the ear and the skull based on the deformation of the soft body, so that the oppressive feeling is reduced; and smooth convex body hugs closely in the position of being connected between the back of the ear and the skull (the root of a ear) after the deformation, and makes first transition body and second transition body can lean on respectively in skull and ear, makes this soft body can keep behind the ear. In particular, the invention is not only suitable for ear-hung type masks, but also suitable for binding type traditional surgical masks.

According to a preferred embodiment, the first transition body and the second transition body are each connected to the two lateral ends of the dorsal lug body with different lateral extension widths, wherein the lateral extension width of the first transition body for fitting against the skull is smaller than the lateral extension width of the second transition body for fitting against the ear.

According to a preferred embodiment, the second transition body is more reversibly deformable than the first transition body. The force between the soft body and the wearer is mostly applied to the first transition body, so that the soft body can deform in a self-coordinated manner based on the difference of the contact portions. The ear protector is mainly used for people with soft ears to wear and prevent the ears from falling off.

According to a preferred embodiment, the first transition comprises tab protrusions and tab extensions that are smoothly connected to each other at least two angles of rise, wherein the angle of rise of the tab protrusions adjacent to the smooth protrusions is smaller than the angle of rise of the tab extensions adjacent to the back ears.

According to a preferred embodiment, the second transition comprises a tab protrusion and a tab extension smoothly connected to each other at least two angles of rise, wherein the angle of rise of the tab protrusion adjacent to the smooth protrusion is smaller than the angle of rise of the tab extension adjacent to the back ear.

According to a preferred embodiment, the ends of the smooth protrusions are substantially flat and reversibly deformable to engage the connection sites to hold each other when subjected to pressure applied to the support slot by the mask ear cord, and the stud protrusions are simultaneously reversibly deformable to hold each other in surface contact with the skull and the ear protrusions are simultaneously reversibly deformable to hold each other in surface contact with the ear.

According to a preferred embodiment, the soft body comprises a release aperture located between and extending longitudinally along the support groove and substantially parallel to the support groove, wherein the release aperture is located simultaneously within the space defined by the lug protrusion and the tab protrusion. And the release hole is positioned in the space limited by the ear sticking protruding body and the head sticking protruding body, so that the ear sticking protruding body and the head sticking protruding body can also generate larger deformation along with the release hole, the clinging force between the ear sticking protruding body and the head sticking protruding body and the ear and the skull is increased respectively, and the contact surface force between the soft body and the ear and the skull is effectively increased and maintained. That is, due to the provision of the release hole: the earbud protrusion can abut against the base of the ear in a manner that applies substantially uniformly the pressure exerted by the mask ear cord to the back of the ear. Namely: the stud protrusion can abut against the skull near the root of the ear in such a manner that the pressure exerted by the mask ear cord is applied substantially uniformly to the back of the ear. The release hole can adaptively and uniformly disperse pressure to the second transition body, the first transition body and the smooth convex body based on pressure change generated by the mask ear rope, so that the soft body can be adaptively and relatively fixedly attached to the behind-the-ear part, the influence of the pressure generated by adjustment on stability is reduced, and the protection of the mask in wearing is ensured.

According to a preferred embodiment, the soft body has a curved body at the tip end thereof, which can be fitted to the inner ear of the wearer, and the curved body has a storage groove which penetrates the holding groove and has a different width. The object placing groove is mainly used for keeping the spectacle frame in the spectacle frame, when the spectacle frame acts in the spectacle frame, the mask ear ropes are pressed on the stressed base part (forming a fixing point) by the spectacle frame, and a wearer can quickly pull the mask part to the lower jaw part based on the base part without causing larger pulling force to the ears,
