Description

  The present invention relates to a dental face cover that covers a patient's face during dental treatment. More specifically, the present invention relates to a dental face cover that prevents water droplets and dust scattered during dental treatment from adhering to the patient's face. Related to face cover.

  In dental treatment, cutting equipment such as an air turbine that cuts, polishes, and removes teeth, polishing equipment such as an ultrasonic scaler, and a syringe that performs drying, cooling, and washing are frequently used.

  Due to the use of these devices, cutting dust, cooling water and the like are often scattered outside the oral cavity of the patient, and in order to prevent this, a dental suction device (vacuum device) is generally used.

  However, while the dental suction device is effective in the treatment of the deep part of the oral cavity, for example, the back teeth, the treatment of the front teeth at the entrance of the oral cavity can prevent the scattering of scattered matter such as cutting dust and cooling water. Therefore, there is a problem in that the scattered matter scatters around the patient's mouth and the patient's face becomes dirty.

  Therefore, as in Patent Document 1 below, the oral cavity is exposed at the center of the sheet covering the lower half of the patient's face in order to prevent the scattered matter from scattering around the patient's oral cavity during dental treatment. There has been proposed a dental face cover in which a fenestration part is formed.

  However, since the dental face cover of Patent Document 1 described below simply covers the sheet on the face, there is a problem that the sheet is displaced from the face due to movements such as opening and closing of the patient's mouth during dental treatment.

  In addition, due to the reclining operation of the examination table during dental treatment, the dental face cover not only shifts from the face, but also shifts downward or falls, and the wind pressure due to the visit of staff such as practitioners and hygienists, There was also a problem that the dental face cover floated off the face or shifted.

  Moreover, in the following patent document 2, similarly to the following patent document 1, in order to prevent the stain | pollution | contamination around a patient's oral cavity, the cover main body which covers the whole face and the opening part which exposes a nose and a mouth were provided in the approximate center of the cover main body. Dental face covers have been proposed.

  In the following Patent Document 2, there is an advantage that the cover body is not easily displaced from the patient's face during treatment by exposing the nose from the opening. However, since the nose is exposed, there is a problem that the scattered matter scattered during the treatment may be scattered over the entire nose, and the adhesion of the scattered matter to the patient's face cannot be sufficiently prevented.

  That is, in Patent Documents 1 and 2 below, scattered objects at the time of dental treatment are prevented from adhering to the face as much as possible. However, this is not sufficient yet, and the patient's discomfort at the time of dental treatment has not been eliminated.

  The present invention has been made in view of the above-mentioned problems of the prior art, and the purpose thereof is to prevent scattered matters such as cutting dust and cooling water generated during dental treatment from adhering to the patient's face, An object of the present invention is to provide a dental face cover that is not easily displaced from the patient's face.

In order to solve the above problems, the present invention provides a dental face cover including a sheet main body that covers at least eyes to a mouth of a patient's face, and an opening for exposing the mouth to the sheet main body.
In the present invention, the opening has a triangular shape that exposes the nose tip including the nose wing together with the patient's mouth by aligning one apex thereof with the patient's nasal apex when the seat body is covered with the face. For example, it is preferable to form a regular triangle having one side of 50 mm to 150 mm.

  Further, the seat body has a pair of ear hook slits that are locked to the patient's ears at symmetrical positions across the opening, and the lower ends of the pair of ear hook slits are respectively For example, the slit length may be 50 mm to 150 mm, and the inclination angle from the upper end to the lower end may be 3 ° to 8 °. preferable.

  In the present invention, the sheet main body may have a structure of at least two layers including a waterproof sheet positioned on the patient's face side and a water absorbent sheet laminated on the waterproof sheet.

  According to the present invention, only the mouth that needs to be opened and closed during dental treatment and the tip of the nose including the nose wings are exposed to the opening formed in the seat body. Since scattered objects such as dust and cooling water can be prevented from adhering to the patient's face, the patient's discomfort can be reduced as compared with the conventional case.

  Further, the seat body can be positioned at a position where the mouth is exposed by a simple operation of placing one apex of the triangular opening on the tip of the nose.

  In addition, since the seat body is formed with a slit that locks the patient's ear, the seat body can be firmly covered with the patient's face, and the seat body can be faced regardless of the patient's movement during dental treatment. Can be prevented from shifting.

  In addition, when it is necessary to remove the seat body from the face such as gargle, for example, the seat body can be removed from the face with one ear engaged with one ear slit, and after gargle, By re-engaging the other ear with the other ear slit, it is possible to smoothly prepare for the next treatment.

  Hereinafter, although the dental face cover of this invention is demonstrated with reference to drawings, this invention is not limited to the following embodiment.

  FIG. 1 shows a dental face cover 1 according to the present invention. This dental face cover 1 is provided in a substantially square cover body 10 and substantially in the center of the cover body 10 to expose the patient's mouth. A substantially equilateral triangular opening 20 is formed, and a pair of ear hooking slits 30 and 31 that are cut into a target position across the opening 20 with a predetermined inclination angle and locked to a patient's ear.

  In the present embodiment, the cover main body 10 is made of a sheet body formed so as to cover at least the mouth of the patient's eyes, and includes a waterproof sheet 11 disposed on the patient's face side, and water absorption laminated on the waterproof sheet 11. A two-layer structure of the sheet 12 is formed.

  In this example, a paper material such as recycled paper is used for the water absorbent sheet 12, and a thin laminate of a synthetic resin such as polyethylene is used as the waterproof sheet 12.

  In the cover main body 10 of the present embodiment, a paper material such as recycled paper is used for the water absorbing sheet 12, and a synthetic resin such as polyethylene is laminated on the back side to form the waterproof sheet 11, so that it is lightweight. The light is transmitted.

  For this reason, when the cover body 10 is covered with the patient's face, the doctor side can be seen through the cover body 11 and the patient does not see the doctor directly. Because he can crawl and know the situation, he can avoid feeling more nervous than necessary because he can feel the doctor's face.

  In the present embodiment, as shown in FIG. 1, the cover body 10 is a dental face cover used for an adult male and has a size covering the chest from the patient's head, for example, a width 10L1 is 450 mm and a height 10L2 is. Although it is formed in a substantially square shape of 450 mm, it is not limited to this.

  The cover body 10 may be any size as long as it can cover at least the mouth of the patient's eyes, and may be appropriately selected according to the size and physique of the patient's face, such as an adult woman or a child.

  In the present embodiment, the opening 20 is formed in a substantially equilateral triangle having one vertex 20 </ b> A on the center line 10 </ b> C of the width 10 </ b> L <b> 1 of the cover body 10. In this example, as with the cover body 10, an adult male As a dental face cover used in the above, it is formed in an equilateral triangle having a side of 100 mm.

  Therefore, as shown in FIG. 3, by positioning the patient's nasal apex at the apex 20 </ b> A of the opening 20, the nose tip including the nose wing and the mouth can be exposed in the opening 20. It has become.

  In this case, since the patient's face is covered so that the center line 10C of the cover body 10 straddles the back of the nose, the cover body 10 is stably covered on the patient's face with the patient's nose as the center line. be able to.

  Also, since only the mouth that needs to be opened and closed during dental treatment and the tip of the nose including the nose wings are exposed from the opening 20, the scattered dust, cooling water, etc. are scattered on the other face. Objects can be prevented from adhering to the patient's face.

  Since the patient's mouth can be easily exposed from the opening by a simple operation of aligning the apex 20A of the opening 20 with the nose tip, the treatment time by using the dental face cover is hindered. Never come.

  In the present embodiment, the opening 20 is described as an example of an equilateral triangle having one side of 100 mm. However, the opening 20 is appropriately selected according to the size and physique of a patient such as an adult woman or a child. Needless to say, for example, the one side may be within a range of 50 mm to 150 mm, and more preferably, the one side may be within a range of 70 mm to 120 mm.

  As shown in FIG. 1, the pair of ear hook slits 30 and 31 is formed at a target position with the opening 20 interposed therebetween with a predetermined inclination angle.

  In this example, as shown in FIG. 1, one ear hooking slit 30 connects the corner portion 10A of the cover body 10 with a width 10L1 direction of 70 mm and a corner portion 10A of the cover body 10 with a height 10L2 direction of 95 mm. The position is an upper end 30a, and is a kerf having a lower end 30b at a position connecting the corner 10A of the cover main body 10 in the width 10L1 direction 75mm and the corner 10A of the cover main body 10 in the height 10L2 direction 165mm.

  Similarly, as shown in FIG. 1, the other ear hook slit 31 also connects the corner portion 10B of the cover body 10 with a width 10L1 direction of 70 mm and the cover body 10 corner portion 10B with a height 10L2 direction of 95 mm. This is a kerf with the upper end portion 31a as the upper end portion 31a, and the position connecting the corner portion 10B of the cover body 10 in the width 10L1 direction 75mm and the corner portion 10B of the cover body 10 in the height 10L2 direction 165mm as the lower end portion 31b. .

  In this example, the pair of ear hooking slits 30 and 31 has a predetermined inclination angle θ, in this example θ, as shown in FIG. 1, by bringing their lower end portions 30b and 31b closer to the opening 20 side. An inclination angle of 6 ° is provided.

  That is, since the base of the human ear is generally provided in an oblique direction from the head side to the chin side toward the center of the face, the ear hook slits 30 and 31 are thus inclined at a predetermined inclination. By providing the corner, the cover body 10 can be stably mounted along the inclination angle of the patient's ear.

  In this example, the ear-hanging slits 30 and 31 are dental face covers used for adult men, and the slit length from the upper end portions 30a and 31a to the lower end portions 30b and 31b is 175 mm, but is not limited thereto. However, similar to the cover main body 10 and the opening 20, it may be appropriately selected according to the size and physique of the patient's face, such as an adult female or a child.

  For example, the slit length of the ear hook slits 30 and 31 is preferably in the range of 50 mm to 150 mm, more preferably in the range of 60 mm to 80 mm, and the inclination angle θ is preferably in the range of 3 ° to 8 °. .

  As described above, the position, size, and range of the opening and the ear hook slit in the dental face cover of the present invention are appropriately selected according to the size and physique of the patient's face. The length of one side, the slit length of the ear hook slit, and the horizontal distance and vertical distance between the opening and the ear hook slit vary depending on the specifications.

  Further, in the present embodiment, the cover body 10 is an example of a two-layer structure in which a water absorbent sheet 11 is made of a paper material such as recycled paper, and a synthetic resin such as polyethylene is laminated on the back side to form a waterproof sheet 12. Although explained, it is not limited to this.

  For example, the cover main body may have a three-layer structure in which a waterproof sheet positioned on the patient's face side, a water absorbent sheet laminated on the waterproof sheet, and a waterproof sheet further laminated on the water absorbent sheet, A multilayer structure in which a waterproof sheet and a water absorbent sheet are appropriately combined may be used.

  In addition, crepe paper having high water absorption may be used as the water absorbent sheet 11, or, for example, a sheet obtained by applying a urethane resin to the water absorbent sheet 11 may be used as the waterproof sheet 12. The material and processing method can be appropriately selected as long as the sheet can be a waterproof sheet having a waterproof property on the surface touching the patient.
