The present disclosure relates to the technical field of medical appliances, and in particular to a face shield.
During medical examinations, treatments, and care, splashes of body fluid, blood, other treatment fluids, and spatters may occur, which will bring great risks to the inspection and treatment operations of medical personnel. Therefore, it is desirable to set up a shield between the medical personnel and the patients to block the contamination and injury of these splashes to faces of the medical personnel. There are two types of protective products on the market, one is eye protection, such as goggles, and the other is facial protection, such as a protective face mask. In general inspection and treatment, the wearer can wear one type of protective appliances. In a circumstance with serious pollution sources, it is necessary to wear the goggles and the protective face mask while wearing protective appliances such as a mask and protective clothing to protect the safety of the wearer. However, the wearing of the goggles, the protective face mask, and the mask at the same time, there will be deep indentations on the wearer's face, undoubtedly causing some damage to the body.
Therefore, how to reduce the facial injury to the wearer while satisfying the protection requirements has become a technical problem to be urgently solved by those skilled in the art.
In view of the above, the technical problem to be solved by the present disclosure is how to reduce the facial injury to the wearer while satisfying the protection requirements. Therefore, a face shield is provided according to the present disclosure.
To achieve the above object, the following technical solutions are provided according to the present disclosure.
A face shield includes:
a transparent face shield body having an eye area in correspondence with the eyes and a face area in correspondence with the face;
an eye mask body extending from the eye area along a thickness direction of the eye mask body, where a hollowed-out area is provided in the middle of the eye mask body, and the eye mask body is of an elastic body structure allowable to be elastically deformed under pressure; and
a headband provided on the face shield body and configured to secure the face shield body to the head, where, when the headband is sleeved on the head, an end face of the eye mask body away from the face shield body is allowable to be fit with a periphery of the eyes.
In one embodiment of the present disclosure, an inner surface of the face shield body is coated with a first anti-fog coating.
In one embodiment of the present disclosure, an outer surface of the face shield body is coated with a second anti-fog coating.
In one embodiment of the present disclosure, the face shield body is made of PET.
In one embodiment of the present disclosure, the eye mask body has an upwardly recessed nose wing portion, and the nose wing portion isolates the hollowed-out area enclosed by the eye mask body from a vent hole of the nose.
In one embodiment of the present disclosure, the eye mask body is made of sponge.
In one embodiment of the present disclosure, the eye mask body and the face shield body are bonded together.
In one embodiment of the present disclosure, two ends of the headband are provided with rivets, and the face shield body is provided with mounting holes for mounting the rivets.
In one embodiment of the present disclosure, the headband has an elastic band structure.
It can be seen from the above technical solutions that, when the face shield of the present disclosure is used, the face shield body is secured onto the head by the headband, the face area of the face shield body is in correspondence with the face, the eye area of the face shield body is in correspondence with the eyes, and the eye mask body is pressed so that the end face away from the face shield body fits with the periphery of the eyes. Since the hollowed-out area is provided in the middle of the eye mask body and the face shield body is transparent, the face shield integrates the functions of the protective face mask and the protective goggles, which greatly reduces the weight of the protective appliance and reduces the facial injury to the wearer while satisfying the protection requirements.

The core of the present disclosure is to provide a face shield to reduce the facial injury to the wearer while satisfying the protection requirements.
Embodiments described hereinafter do not intend to limit the scope of the present disclosure as defined in the claims. Further, the entire contents of the configurations described in the following embodiments may not be necessary for the solutions of the present disclosure defined in the claims.
Referring to
When the face shield of the present disclosure is used, the face shield body 100 is secured onto the head by the headband 300, the face area 101 of the face shield body 100 is in correspondence with the face, the eye area 102 of the face shield body 100 is in correspondence with the eyes, and the eye mask body 200 is pressed so that the end face away from the face shield body 100 fits with the periphery of the eyes. Since the hollowed-out area 201 is provided in the middle of the eye mask body 200 and the face shield body 100 is transparent, the face shield integrates the functions of the protective face mask and the protective goggles, which greatly reduces the weight of the protective appliance and reduces the facial injury to the wearer while satisfying the protection requirements.
It should be noted that the face shield body 100 has a planar structure or a curved surface structure. Preferably, the face shield body 100 has a curved surface structure, which makes the face shield body 100 have a wide visibility range. Alternatively, the face shield body 100 has a planar structure before being worn, and when worn, the face shield body 100 changes into a curved surface structure under the pulling force of the headband 300. Any structure of the face shield body 100 capable of protecting the face is within the protection scope of the present disclosure.
The face shield body 100 of the present disclosure not only has the function of face protection. In addition, a portion of the face shield body 100 in correspondence with the hollowed-out area 201 does not affect the normal field of vision, and in combination with the eye mask body 200, is equivalent to the function of the goggles. Since the eye mask body 200 is of the elastic structure and is deformed when pressed, the eye mask body 200 can be kept sealed around the eyes, so as to achieve the purpose of eye protection. It can be seen that the face shield body 100 of the present disclosure in combination with the eye mask body 200 can be used as the goggles. Besides, some wearers have limited vision. With regards to this, the hollowed-out area 201 enclosed by the eye mask body 200 has enough space for wearing short-sighted glasses, far-sighted glasses, and various glasses. The wearer can still have a clear vision even when wearing glasses.
Alternatively, in order to improve the protection level, the hollowed-out area 201 enclosed by the eye mask body 200 may be large enough for wearing goggles.
In a case that the face shield is worn in a circumstance with a large temperature difference, the portion of the face shield body 100 in correspondence with the hollowed-out area 201 will fog up, thereby affecting the wearer's field of vision. In order to reduce fogging, an inner face of the face shield body 100 in correspondence with the hollowed-out area 201 is coated with a first anti-fog coating. In order to reduce the processing difficulty, the entire inner surface of the face shield body 100 is coated with the first anti-fog coating. Further, when a temperature difference occurs in the circumstance, an outer surface of the face shield body 100 may also fog up. In order to reduce the probability of fogging on the outer surface of the face shield body 100, the outer surface of the face shield body 100 is coated with a second anti-fog coating.
The face shield body 100 is made of lightweight plastic to reduce the pressure on the wearer. Preferably, the face shield body 100 is made of PET.
The function of the eye mask body 200 is to ensure a tight seal around the eyes, so as to meet the protection requirements of the goggles. The eye mask body 200 is of an elastic structure, for example, it is made of sponge or latex. When the headband 300 tightens the face shield, a squeezing force is generated between the eye mask body 200 and the wearer's face. Since the eye mask body 200 is of the elastic structure, the eye mask body 200 can be deformed correspondingly to the curve surface of the wearer's face to ensure the fit with the face and improve the sealing. In addition, since the sponge and latex are soft, it is relatively gentle when the eye mask body 200 is pressed against the face, and the sense of pressure is also light.
Specifically, an end face of the eye mask body 200 away from the face shield body 100 has a first fitting surface that fits with an upper portion around the eyes, a second fitting surface that fits with a lower portion around the eyes, a third fitting surface that fits with a left portion around the eyes, and a fourth fitting surface fits with a right portion around the eyes. The first fitting surface, the second fitting surface, the third fitting surface and the fourth fitting surface can ensure the isolation of the eyes from the outside, and shapes of the first fitting surface, the second fitting surface, the third fitting surface, and the fourth fitting surface are in correspondence with the corresponding surface of the face.
In order to isolate a vent hole of the nose from the hollowed-out area 201, the eye mask body 200 has an upwardly recessed nose wing portion. The nose wing portion isolates the hollowed-out area 201 enclosed by the eye mask body 200 from the vent hole of the nose. In this way, when worn, the eye mask body 200 is located above the nose, the nose is not in the hollowed-out area 201 enclosed by the eye mask body 200, and the vent hole of the nose may be isolated from the hollowed-out area 201, so that the air exhaled by the wearer is vented from a lower end of the eye mask area. Therefore, the problems of goggles fogging up, visibility being reduced, and the sight being hindered, which are caused by part of the air escaping from two sides of the nose wing portion due to long term operation or communication while wearing the face shield, can be avoided.
In order to ensure the protection level, the face shield body 100 is of an integrated structure, and the eye mask body 200 and the face shield body 100 are bonded together, so that the face shield body 100 is free of perforation, which further ensures the sealing effect of the eye mask body 200 and the face shield body.
The headband 300 is directly bonded to the face shield body 100, or two ends of the headband 300 are provided with rivets, and the face shield body 100 is provided with mounting holes for mounting the rivets. Alternatively, the face shield body 100 is provided with rivets, and the headband 300 is provided with mounting holes cooperating with the rivets. Any configuration capable of realizing detachable assembly of the headband 300 with the face shield body 100 is within the protection scope of the present disclosure. In addition, the headband is made of an inelastic material, or in order to improve the comfort of the wearer, the headband 300 has an elastic band structure.
Based on the above description of the disclosed embodiments, those skilled in the art can implement or use the present disclosure. Various modifications to these embodiments are apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure is not limited to the embodiments described herein but confirms to a widest scope in accordance with principles and novel features disclosed in the present disclosure.
