Description

[Detailed description of the invention] [Industrial application field] This invention is used to collect blood, secretions, pus, etc. that flow from the affected area when doctors, dentists, etc. diagnose or perform surgery on the affected area of a patient. Regarding face masks to protect doctors' faces from body fluids, more specifically, disposable paper masks that are commonly used by doctors, dentists, etc. when making diagnoses or performing surgeries. In addition to a cloth mask or cloth mask, it is also worn on the outside of the mask, and it can adhere to the surgeon's eyes, upper jaw, lower jaw, etc., and there is a high possibility of infection such as AIDS or serum hepatitis from microscopic scratches in those areas. The present invention relates to a surgical face mask for preventing the entry of highly pathogenic pathogens.

[Prior Art] When doctors, dentists, etc. make a diagnosis or perform surgery on an affected area, they usually use a surgical cap and a disposable mask made of paper or a mask made of cloth.

Surgical masks are used to prevent the doctor's exhaled air from hitting the patient's face and causing discomfort to the patient, and to prevent influenza and other germs from adhering to the affected area during surgery due to the doctor's coughing or sneezing. It also has the purpose of preventing the affected area from becoming contaminated.

On the other hand, from the doctor's perspective, it also serves to prevent the patient's body fluids, such as blood and secretions, from entering the surgeon's mouth and nostrils.

In particular, when cutting bones etc. using a rotary saw, there is a possibility that a considerable amount of blood may scatter towards the eyes and facial skin of the surgeon who is observing the affected area with his/her face close to the affected area. There are quite a lot of them.

However, the eyes and lower jaw, which were not covered by the mask, were left unprotected.

In conventional diseases, even if the patient's blood, saliva, secretions from the affected area, etc. may come into contact with the doctor's eyes, lower jaw, or other areas not covered by the mask, the patient's blood, saliva, and secretions from the affected area may come into contact with the doctor's eyes, lower jaw, or other areas that are not covered by the mask. This was because there was a general empirical belief that doctors would not become infected if they were cleaned and disinfected afterwards.

[Problem that the invention aims to solve] In recent years, there have been cases where trace amounts of body fluids such as blood and secretions from patients can be transmitted to humans through small wounds on the skin surface, such as in cases of hepatitis B and AIDS (acquired immunodeficiency syndrome). Infection occurs immediately when the virus enters circulating blood, and after an incubation period corresponding to each disease, the disease develops at an extremely high rate and often leads to death.Moreover, unlike AIDS, the pathogen itself has not been identified and cannot be treated. This situation has led to concerns as there is no established method for this.

From this point of view, it is important for doctors who diagnose or operate on patients with these diseases to avoid exposing these pathogens to areas such as the eyes, upper part of the face, and lower jaw that are not protected by regular masks during surgical procedures. When it adheres to
There was a growing concern that these pathogens could enter the surgeon's blood through tiny wounds and cause illness.
Physicians have become increasingly fearful of operating on this type of patient, and there has been a strong demand for means that can protect the eyes and face from contamination.

[Means for solving the problem] The present invention was made to solve the above problem, and it is a mask that covers the entire face of the operator, on the outside of the paper mask that has been used conventionally. A transparent protective plate or shield is placed at a distance of 10 to 20 mm from the top of the surgeon's nose, extending along the contour of the face from the forehead to below the mandible to cover the entire face of the surgeon. , to prevent direct contact with contaminated body fluids.

Use a mounting band on the upper edge of the protective plate of this face protection mask that has enough room to go around the surgeon's head once, or one that can be easily attached to the surgeon's forehead and can be easily attached and detached by the surgeon. . The attachment device is not limited to the band type, and may be a headphone type, but since the surgeon often wears a head cap during surgery, the band type is convenient.

A forehead pad was attached to the back of the mounting band to maintain an appropriate distance between the surgeon's face and the protective plate.

[Embodiment] Fig. 1 is a schematic perspective view showing one embodiment of the face mask of the present invention attached to the face of an operator, and the reference numeral 10 in the drawing indicates the entire face mask, and 11 indicates the protective plate. , 12 indicates a mounting band, and 13 indicates a forehead pad for mounting. Reference numeral 14 is a one-touch fixing member called Magic Band (registered trademark) attached to the wearing band at the position of the back of the head on the left side of the user in the drawing, and the raised part of the wearing band wrapped around the back of the head from the right side It is intertwined with the attached back surface 12' and fixed at a predetermined position depending on the size of the surgeon's head.

The transparent protective plate 11 that constitutes the main body of this protective mask is made of polyethylene, polystyrene, polyvinyl chloride, etc., which can prevent static electricity, and is made of a plastic sheet with a thickness of about 0.2 to 0.5 mm and a width of about 300 mm. It is cut into a rectangular shape with a height of about 200mm, and finishing processes such as corner cutting and rounded edges are applied. This protective plate 11 has a mounting band 1 whose upper edge is a part for mounting on the forehead of the operator.
2.

This mounting band 12 is made of a raised fiber material called nylon velveteen 12' on the back side of the vinyl sheet.
This is a composite material that is fused together, and this raised surface easily entangles with the removable binding band 16 called Magic Tape (registered trademark), which is the mating partner, making the binding possible.

This mounting band 12 is spot-bonded to the transparent protection plate by a heat fusion method, as shown by reference numeral 15.

The attachment pad 13 of the forehead rest has a crescent shape with substantially the same upper and lower surfaces and a rectangular cross section as shown in FIG. 2, and the inside is filled with a porous material such as styrofoam.

The inner side of the forehead pad 13, ie, the portion 16 that directly contacts the forehead of the practitioner, is lined with nylon velveteen material to ensure a good fit with the forehead of the practitioner.

After the mounting band 12 is positioned by tightening the back of the head, it is fixed with the one-touch fixing member as described above.

As shown in FIG. 2, the forehead pad 13 and the upper edge of the protective plate 11 are joined together by heat-sealing only the central portion 17, which occupies approximately one-half of the height and width of the pad. Both edges are not fused and are kept open (18).

The purpose of this design is to create a buffer that prevents the protective plate from being unnaturally deformed due to excessive force, even if the degree of curvature of the protective plate varies depending on the size of the forehead of the surgeon. This is to fulfill the role of

[Effects] The protective mask of the present invention is constructed as described above, so the operator can put it on with one touch, and the transparent plastic surface protects the lower part of the surgical cap from the lower jaw to the lower part. Therefore, the entire face of the operator can be prevented from being contaminated. In addition, since the mask surface is transparent and flexible,
The affected area, the operator's hands, the tips of surgical instruments, etc. can be fully observed, and if blood or other body fluids are attached, cleaning and disinfection are easy and hygienic.

Furthermore, even when worn, a 10 to 20 mm gap is maintained between the inner surface of the mask's protective plate and the tip of the surgeon's nose, and an even wider space is secured between the cheeks and eyes, allowing air to circulate. This is sufficient to prevent the surface of the protective plate or the operator's glasses from fogging up due to the operator's breathing, which would interfere with the operation.

Furthermore, since the structure is simple and the materials are ordinary materials that are easily available, the manufacturing cost is low and it does not impose a heavy burden on hospitals and the like to keep them on hand.
