Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a face protection shield, and more particularly, to a shield for protecting a face, particularly both eyes, from splashing of blood or body fluid of a patient during a surgical operation.

[0002]

2. Description of the Related Art When a medical worker faces a patient in a surgical operation, an outpatient procedure, or the like, there is a danger that blood or body fluid will scatter from the affected area and enter the worker's face, especially the eyeball.
May cause bacterial or viral infection. Therefore, conventionally, medical goggles have been worn or a mask with an eye shield has been used. The medical goggles are eyeglasses type, fixed and attached to both auricles as if wearing normal glasses, and covered around the both eyelids with a transparent plastic cover so that they can deal with scattering from the surroundings. It has become. After use, clean and disinfect
Reused. On the other hand, a mask with an eye shield is made so that a transparent synthetic resin film whose front and rear surfaces have been subjected to anti-fog treatment is mounted on the same plane as the mask at the upper edge of the mask so as to cover the entire face. A notch is provided at the center of the lower part of the eye shield, and is fixed to the mask with an adhesive or the like so as to be positioned on the nose of the wearer when the eye shield is worn. For example, Japanese Patent Application No. 7-205131 and Japanese Utility Model Application No.
No. 9345 and the like.

[0003]

However, the conventional goggles described above have a problem that only the periphery of the eyelid can be protected, and the face other than the portion covered by the other mask is exposed. In addition, there is a disadvantage that the feeling of wearing is poor because it is in close contact with the face when worn, and furthermore, it takes a lot of time, labor and cost to wash and disinfect the goggles for reuse.

Further, even in a mask with a shield, when the mask is worn, the shield is located on the same plane as the mask surface, so that the mask is in close contact with the face to give a feeling of pressure or obstruction to the wearer, and also to cause the wearer to exhale. However, there is also a problem that the inner surface of the shield is fogged due to leakage from a gap above the mask, which hinders medical operation.

Further, once the shield is removed from the mask, it cannot be remounted and the mask itself has to be replaced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to prevent the wearer's face, especially both eyes, from scattering of blood or body fluid of a patient during a surgical operation. To provide a protective shield that protects and removes a feeling of pressure and obstruction at the time of wearing, prevents fogging of the shield due to exhalation, and furthermore, it is extremely easy to install and replace the shield while wearing a mask or a cap. It is in.

[0007]

The technical means taken by the present invention to achieve the above object is to provide a shield made of a transparent elastic member having a front surface and a back surface subjected to anti-fog treatment,
At the upper and lower four corners of the upper edge and the lower edge of the shield, a structure having a bent portion bent at an obtuse angle so as to have a certain distance between the face and the face is further contacted with the face. There is a margin for attaching an adhesive tape, and the adhesive tape allows the upper part to be fixed to the frontal surface of the cap and the lower part to be fixed to the front surface of the mask.

[0008] The folded portion and the margin portion are also made of the same transparent elastic member as the shield body.

[0009] The length of the above-mentioned folded portion is set so as not to cause trouble even for the spectacle wearer. Even if the length of the folded portion between the upper edge and the lower edge of the shield is the same, the upper edge is longer. It may be longer.

[0010] The face protection shield is a disposable type, and ideally the material that can be incinerated is ideal.
It is sufficient that the elastic member is transparent and has a hardness capable of maintaining the shape. Useful materials include polyesters such as polyethylene terephthalate, polyolefins such as polystyrene-copolyacrylonitrile, polyethylene or copolymers thereof, and polyacrylic acids such as polycarbonate, polymethyl methacrylate, polyethyl acrylate or copolymers thereof. Examples include esters, polysulfone, polyvinylidene chloride or polyvinylidene fluoride, and cellulose derivatives such as cellulose acetate butyrate.

Considering the case where the adhesive tape is directly attached to the face, it is preferable that the adhesive tape does not have skin hypersensitivity, and it is sufficient that the adhesive tape has such an adhesive strength that it does not peel off naturally during attachment.

[0012]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a face protection shield of the present invention, FIG. 2A is a top view thereof, and FIG. 2B is a side view thereof. As shown in FIGS. 1 and 2, the face protection shield comprises a shield main body 1, folded portions 2a and 2b at four upper and lower right and left corners, and a marginal portion 3a and 3b at the tip. Have been. Bends 4 are formed on the left and right sides of the shield body for blood and body fluid scattered from the side.

The front and back surfaces of the shield are provided with anti-fog treatment, and have a size sufficient to completely cover the face other than the face covered with the mask and the cap, and It is sufficient that the visual field and operation of the camera are not hindered.

Folded portions 2a and 2b at four corners of shield
Must be long enough not to cause any trouble even for spectacle wearers, but if it is too long, the shield body will be poorly fixed, and even if the head moves slightly, There is a danger of shaking. Therefore, it is appropriate that the length is around 3 to 5 cm.

The lengths of the folded portions 2a and 2b at the upper and lower edges may be the same, but the upper edge 2a may be longer than the lower edge 2b and the shield surface may be inclined obliquely downward. . The reason for the inclination is that the line of sight of the wearer at the time of the surgical operation is often directed downward, and the distortion of the field of view can be reduced by arranging the shield surface at right angles to the line of sight. Further, the inclination angle of the shield can be freely selected by changing the positions where the adhesive tapes on the upper and lower edges are attached and changing the obtuse angles θ1 and θ2 with the shield. FIG. 3 shows a side view when the shield is mounted.

The width of the folds 2a and 2b is only required to be such that the shield can naturally draw a curve along the curve in the lateral direction of the face in both the upper and lower directions.

The adhesive portions 5a and 3b are provided with adhesive tapes 5 on the adhesive surfaces, respectively. 3a is fixed to the cap of the wearer and 3b is fixed to the front surface of the mask. The size of the margin portion may be any size as long as it can be securely fixed to the cap or mask with the adhesive tape on both the upper and lower sides. The upper and lower portions may be the same size or 3a may be larger. FIG. 4 shows an embodiment equipped with the face protection shield of the present invention.

In another embodiment, only the margin at the lower edge of the eye shield is fixed to the mask, and after the mask is worn, it may be fixed to the cap with an adhesive tape at the upper edge of the shield (FIG. Not shown).

[0019]

According to the first and second aspects of the present invention, the face protection shield for a surgical operation protects the wearer's face, especially both eyes, from scattering of blood or body fluid of a patient during a surgical operation. In addition, it is possible to remove a feeling of pressure or blockage at the time of wearing, and to prevent clouding of the shield due to exhalation. Further, it is possible to provide a protective shield in which the shield can be extremely easily mounted and replaced while the mask or the cap is being worn.
