A plan view for explaining how the endoscope mask is used Enlarged sectional view of IV-IV part in FIG. FIG. 4 is an enlarged cross-sectional view of an endoscope mask according to a second embodiment;

The illustrated embodiments will be described below. FIG. 1 shows a plan view of an endoscope mask 1 according to a first embodiment. When conducting a medical examination (hereinafter referred to as a medical examination, etc.), the patient's mouth is covered to prevent the discharge from the patient from scattering.
Since the endoscope is conventionally known, a detailed description thereof will be omitted. Ta having a diameter of about 9 mm is generally used.
3 and 4, the patient holds the mouthpiece 11 in his or her mouth when performing a diagnosis using an endoscope. The endoscope tube Ta is passed through and inserted into the patient's esophagus or the like.

The endoscope mask 1 of this embodiment includes an insertion sheet 2 through which the endoscope tube Ta of the endoscope can be inserted, a cover sheet 3 provided so as to surround the insertion sheet 2, and the Straps 4 are provided as retaining means for fixing the cover sheet 3 to the patient. Here, in the following description, the up-down direction is defined as the direction connecting the patient's head and jaw, and the left-right direction is defined as the direction connecting the patient's ears.
The insertion sheet 2 is made of a material that is transparent, flexible, and slightly stretchable, and can be made of silicon, urethane, elastomer, or the like, and has a thickness of 1 mm or less. It is desirable to use
Here, the term “transparency” includes semi-transparency that is somewhat turbid as long as the appearance of the opposite side can be confirmed through the cover sheet 3 .
Although the insertion sheet 2 of this embodiment has an oval shape that is elongated in the horizontal direction, it may have an elliptical shape or a rectangular shape.
A transparent double-sided tape 5 is attached to the patient-side surface of the insertion sheet 2 so that the distal end portion of the mouthpiece 11 held by the patient during examination using an endoscope as will be described later. It is designed to be adhesively fixed to the

The cover sheet 3 is made of, for example, a non-woven fabric having a thickness of about 0.5 mm. The cover sheet 3 has a substantially rectangular shape elongated in the horizontal direction, and covers substantially the lower half of the patient's face including the mouth. It has a size of about
An elliptical mounting hole 3a is formed substantially in the center of the cover sheet 3 so as to match the shape of the insertion sheet 2, and the outer peripheral edge of the insertion sheet 2 and the inner peripheral edge of the mounting hole 3a are mutually connected.

Next, an endoscope insertion port 6 for inserting an endoscope tube Ta is formed in a substantially central portion of the insertion sheet 2 .
The diameter of the endoscope insertion port 6 is set to be the same as or slightly smaller than that of the endoscope tube Ta. When the diameter of the endoscope insertion opening 6 is made smaller than the diameter of the endoscope tube Ta, the insertion sheet 2 has elasticity, but if the diameter is made too small, insertion and removal of the endoscope tube Ta is hindered. Therefore, it is desirable to set the diameter of the endoscope insertion opening 6 to about 50% of the diameter of the endoscope tube Ta.
The diameter of the endoscope insertion opening 6 can be appropriately changed according to the material and thickness of the insertion sheet 2 .
By doing so, the endoscope insertion port 6 can be maintained in close contact with the endoscope tube Ta, and the discharge from the patient can be prevented from passing through the endoscope tube Ta and the endoscope insertion port 6. can be prevented from leaking out of the gaps.
The double-sided tape 5 is attached to the patient side of the insertion sheet 2 so as to surround the endoscope insertion opening 6 (see FIG. 3). It is adapted to be adhered to the tip of the piece 11 .

Furthermore, suction insertion holes 7 for inserting suction tubes Tb (see FIG. 4) are formed at positions adjacent to the endoscope insertion hole 6 on the right and left sides of the insertion sheet 2 . there is
The suction tube Tb sucks saliva accumulated in the oral cavity of the patient and discharge material discharged between the patient and the endoscopic mask 1 during examination using an endoscope. , and is connected to suction means (not shown).
The position where the suction insertion port 7 is formed is formed in accordance with the position of the through hole 13 a formed in the flange portion 13 of the mouthpiece 11 . Further, it is desirable that the diameter of the suction insertion port 7 is set to be the same as or slightly smaller than that of the suction tube Tb, but it is not always necessary.

The suction tube Tb is adapted to be inserted from the suction insertion port 7 only when collecting the above-mentioned discharge matter, and normally, the suction tube Tb is provided on the patient side surface of the insertion sheet 2 as an opening/closing means.

A method of using the endoscope mask 1 according to the present embodiment will be described below.
3 and 4 show an example of the state of use of the endoscopic mask 1. When performing a medical examination using an endoscope, the patient uses the mouthpiece shown in FIGS. 11 is held in the mouth, and the patient's face is covered with the endoscopic mask 1. As shown in FIG.
A conventional mouthpiece 11 can be used as the mouthpiece 11, and even if a mouthpiece 11 having a configuration other than that described here is used, the endoscope mask 1 of the present embodiment can be used. It is possible to use.
The mouthpiece 11 is composed of a cylindrical portion 12 for a patient to hold, and a flange portion 13 formed at the distal end of the cylindrical portion 12, that is, a portion projecting outward from the patient's mouth.
The cylindrical portion 12 has an outer diameter and length suitable for a patient to hold in his/her mouth during examination, etc., and the inner diameter of the cylindrical portion 12 is such that the endoscope tube Ta can be inserted and removed. It is set to a diameter of about
The flange portion 13 is curved along the shape of the patient's face, and a portion adjacent to the cylindrical portion 12 has a flat surface. In addition, through holes 13a are formed in portions of the flange portion 13 adjacent to the cylindrical portion 12 on the left and right sides so as not to impede breathing of the patient.

When the patient undergoes endoscopic treatment, the patient lies down with the right side of the body downward and holds the mouthpiece 11 in the patient's mouth. At this time, the through holes 13a formed in the flange portion 13 are aligned substantially vertically because the patient is lying down.
Subsequently, the patient is fitted with the endoscope mask 1 of the present embodiment. At this time, the release paper of the double-sided tape 5 provided on the patient side of the insertion sheet 2 is peeled off as shown in FIG.
At this time, the endoscope insertion opening 6 provided in the endoscope mask 1 is aligned with the center of the cylindrical portion 12 of the mouthpiece 11, and the suction insertion openings 7 are aligned with the flange portion 13 of the mouthpiece 11. The insertion sheet 2 and the mouthpiece 11 are adhered in a state of being aligned with the position of the through hole 13a.
Subsequently, the straps 4 provided on both sides of the cover sheet 3 are engaged with the patient's ears, whereby the endoscopic mask 1 is attached to the patient, and the lower half of the patient's face including the mouth is covered with the cover sheet 3. and the insertion sheet 2 . Since the patient is lying down as described above, the endoscope insertion opening 6 and the suction insertion opening 7 are aligned substantially vertically.

Subsequently, the doctor operates the endoscope to insert the endoscope tube Ta into the endoscope insertion opening 6 of the endoscope mask 1, and then through the tubular portion 12 of the mouthpiece 11. Let
At this time, the tip of the endoscope tube Ta that has passed through the mouthpiece 11 can be observed from the outside of the endoscope mask 1 by a doctor through the transparent insertion sheet 2. A doctor can guide the endoscope tube Ta into the patient's esophagus without being hindered from normal operations.
Further, the doctor inserts the endoscope tube Ta into the patient for examination or the like. , and the insertion sheet 2 is adhered to the mouthpiece 11 with the transparent double-sided tape 5, so that the endoscope mask 1 may be displaced during operation. is less likely to occur.

When the examination using the endoscope is performed in this way, the patient may cough or vomit the contents because the endoscope tube Ta is inserted into the esophagus.
Even in such a case, since the patient's mouth is covered with the endoscopic mask 1, the endoscopic mask 1 can prevent the discharge from scattering, and the endoscope can be used. It is possible to prevent infection by viruses and bacteria contained in the discharged matter that adheres to the operating doctor or medical staff.
At this time, since the endoscope insertion opening 6 into which the endoscope tube Ta is inserted is in close contact with the endoscope tube Ta, it is possible to prevent discharge from leaking through the gap.
Furthermore, the suction insertion port 7 is closed by a valve member 8, and even if the patient vigorously spouts the discharge material, the valve member 8 is in close contact with the insertion sheet 2 from the patient side. The opening of the member 8 is prevented, and leakage of the discharge can be prevented.

Next, when the patient's mouth discharges between the endoscopic mask 1 and the patient's face, or when saliva accumulates in the patient's oral cavity during treatment, the suction means is used. These can be collected.
A doctor or a medical worker who assists him inserts the suction tube Tb of the suction means into the suction insertion port 7 . The suction insertion openings 7 are provided above and below the endoscope insertion opening 6. Since the discharge flows downward, the suction tube Tb is inserted into the suction insertion opening 7 positioned below. .
Then, the tip of the suction tube Tb presses the valve member 8 to open toward the patient, allowing the suction tube Tb to be inserted between the endoscope mask 1 and the patient's face or into the patient's oral cavity. can be done.
Also in this case, since the insertion sheet 2 is transparent, the tip position of the suction tube Tb can be easily recognized from the outside, and the discharged material can be collected quickly.
When the collection of the discharged matter is completed, the suction tube Tb is quickly pulled out from the suction insertion port 7, and thereafter the valve member 8 is brought into close contact with the insertion sheet 2 again by its elastic force, and the suction insertion port 7 is closed again. It will be done.

As described above, according to the endoscope mask 1 according to the present embodiment, by inserting the endoscope tube Ta through the endoscope insertion opening 6 of the insertion sheet 2, the patient can use the endoscope as an endoscope mask. A medical examination or the like can be performed with an endoscope while wearing the mask 1 .
At this time, since the insertion sheet 2 is transparent, even when the endoscopic tube Ta is inserted into the mouth of the patient wearing the endoscopic mask 1, it is possible to insert the endoscopic tube Ta from the outside of the endoscopic mask 1. It is possible to visually recognize the position of the tip of the endoscope tube Ta, and the operation of the endoscope by the medical staff is not hindered.
In addition, since the patient's mouth is covered with the insertion sheet 2 and the cover sheet 3 during examination by the endoscope, even if the patient blows out the discharge from the mouth, the discharge can be prevented from scattering. It is possible to prevent discharge from adhering to medical personnel.
Next, by making the diameter of the endoscope insertion port 6 smaller than the diameter of the endoscope tube Ta, a gap is prevented from being formed between the endoscope tube Ta and the endoscope insertion port 6. Therefore, it is possible to prevent the discharge from leaking through the gap.
Next, a transparent double-sided tape 5 for adhering to the tip of the mouthpiece 11 held by the patient is provided on the patient-side surface of the insertion sheet 2, so that the mouthpiece 11 and endoscopic vision during treatment can be improved. There is no deviation from the endoscope mask 1 and it does not interfere with the operation of the endoscope.
Next, at a position adjacent to the endoscope insertion opening 6 in the insertion sheet 2, a suction insertion opening 7 for inserting the suction tube Tb is formed so that the patient and the endoscope mask 1 are connected. It is possible to collect the discharge that has leaked out in between and saliva accumulated in the oral cavity of the patient by the suction tube Tb. At that time, since the insertion sheet 2 is transparent, the suction tube Tb can be easily operated.
Since the valve member 8 is provided at the opening of the suction insertion port 7 on the patient side, the suction insertion port 7 is closed by the valve member 8 when the suction tube Tb is not inserted, and the patient sprays. It is possible to prevent the ejected substance from scattering.
Next, when the through hole 13a is provided in the flange portion 13 formed at the tip of the mouthpiece 11 as shown in FIG. Since it is provided, the operation of the suction tube Tb is not hindered.
