2. Description of the Related Art Generally, a person sleeps for 7 hours a night. Some people have more than 30 apnea episodes during REM and NREM sleep during this 7-hour sleep, or 5 or more apnea episodes per hour during sleep. When called apnea.
The apnea here refers to a case where no airflow is observed in both the mouth and the nose for 10 seconds or more.

When a patient with such an apnea syndrome falls asleep, the upper respiratory tract is obstructed and apnea begins, causing the patient to become awake and awake. Upon awakening, the blocked airway is opened and breathing resumes. Patients with apnea recapitulate this state during sleep, but repeated wakefulness causes insufficient sleep, and various effects on the circulatory system are associated with apnea and ventilation efforts. As a result, it causes various complications such as arrhythmia, hypertension, myocardial infarction, cerebrovascular accident, and sudden death.

Therefore, in order to prevent such a dangerous complication, a medical mask 10 as shown in FIG. 10 is conventionally used.
One is worn during sleep. The medical mask 101 will be described. The medical mask 101 has a substantially triangular base 102 made of synthetic resin. This substantially triangular base 10
An upper fixing piece 105 and lower fixing pieces 106 and 107 are formed so as to project from the three apexes of 2. The upper fixing piece 105 is provided with two band insertion holes 112, 112. One end of a stretchable upper fixing band 108 is inserted into the insertion holes 112, 112, and the other end is wrapped around the patient's forehead. The lower fixing pieces 106 and 107 are also provided with two band insertion holes 113 and 113.
One end of a telescopic lower fixing band 109 is inserted into 3, 113, and the other end is wrapped around the cheek of the patient. The medical mask 101 is fixed to the face by the lower fixing band 109 and the upper fixing band 108.

The central portion of the base 102 forms a nasal bursa portion 103 which projects in the shape of a triangular pyramid and covers the nose portion. An oxygen supply tube 104 is formed so as to project from the nose pack 103. The oxygen supply pipe 104 has a rubber oxygen conduit 11

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of a medical mask worn by a patient with apnea syndrome according to the present invention, and FIG. 2 is a perspective view thereof. The medical mask 1 is made of synthetic resin and has a substantially triangular shape. Have two. An upper fixing piece 5 and lower fixing pieces 6 and 7 are formed so as to project from three apexes of the substantially triangular base 2. The upper fixing piece 5 is provided with two band insertion holes 12 and 12, and these insertion holes 12 and 12 are made of elastic upper fixing bands 108 as shown in FIG.
One end is inserted and wrapped around the patient's forehead as shown in FIG. The lower fixing pieces 6 and 7 are also provided with two band insertion holes 13 and 13, respectively.
One end of a telescoping lower fixation band 109 as shown at 0 is inserted and the other end is wrapped around the cheek of the patient as shown in FIG. The medical mask 1 is fixed to the face by the lower fixing band 108 and the upper fixing band 109.

A central portion of the base 2 projects into a triangular pyramid shape to form a nasal capsule portion 3 covering the nose. An oxygen supply tube 4, which is an oxygen supply tool for supplying oxygen into the medical mask 1, is formed so as to project from a substantially central portion of the nasal capsule 3. One end of a rubber oxygen conduit 110 as shown in FIG. 10 is connected to the oxygen supply pipe 4, and the other end is connected to an oxygen supply device 111. Two air pressure adjusting holes 14, 14 are formed above the oxygen supply pipe. Further, a dew condensation prevention tool (hereinafter, referred to as a “mask heater”) 20 including a tubular heater bent in a substantially triangular shape along the peripheral edge of the triangular nasal capsule portion 3 is attached. A conductor 21 is connected to one end of the mask heater 20 for the dew condensation prevention tool, and a switch breaker 22 and an outlet 23 are attached to the conductor 21.

A specific structure of the tubular mask heater 20 will be described with reference to FIG. The annular mask heater 20 has a thickness of about 5 mm, a width of 10 mm, and a length of 120 to 30.
There is up to 0 mm. Reference numeral 25 denotes a heating element mainly composed of carbon. A lead wire 26 is provided through the heating element 25, and the heating element 25 having the lead wire 26 provided therethrough is covered with an insulator 24. If you connect this lead wire 26 to the power supply,
The heating element 25 is adapted to generate heat. The annular mask heater 20 configured in this manner is provided outside the substrate 2 so as to heat the peripheral edge of the triangular nose wrap portion 3. As shown in FIG. 2, a cushion material 15 is attached to the back side of the base 2, that is, the inside of the medical mask 1 so as to provide a cushioning function when the medical mask 1 is worn on the face.

The method of using the medical mask 1 having such a structure will be described. A patient with apnea syndrome fixes the medical mask 1 to which the mask heater 20 is attached to the face as shown in FIG. . If an apnea is detected during sleep by a computer (not shown), the oxygen supply device 111 operates, oxygen passes through the oxygen conduit 110 and is sent to the oxygen supply pipe 4 of the medical mask 1 to supply the oxygen. The oxygen introduced into the mask 1 through the tube 4 allows the patient with apnea to breathe. Oxygen sent to the oxygen supply pipe 4 is different from the atmosphere as described above, and is a gas that is particularly dry or dehumidified. There is a temperature difference between the temperature of oxygen and the temperature of the atmosphere outside the mask 1, and this temperature difference causes dew condensation inside the medical mask 1. However, in the medical mask 1, the heating element 25 of the mask heater 20 attached to the peripheral edge of the mask heats up to heat the atmosphere outside the nose wrap portion 3 of the mask 1. By heating this atmosphere, there is no difference in temperature between the inside of the medical mask 1 and the outside of the medical mask 1, and no dew condensation occurs inside the medical mask 1. As a result, the conventional medical mask 1
Like No. 01, the patient does not feel discomfort when the dew droplets adhere to the patient's face, and the trouble of removing the dew droplets accumulated inside the mask one by one is eliminated.

FIG. 3 shows the mask heater 2 for preventing dew condensation.
0 is a front view of another example of No. 0, and FIG. 4 is a perspective view thereof. As shown in the figure, in the medical mask 1, the mask heater 30 has a planar shape. Except for the fact that the mask heater 30 is a sheet like this,
Since the medical mask 1 has the same structure as that shown in FIGS. 1 and 2, the mask heater 30 will be mainly described below.

As shown in FIGS. 3 and 4, in the medical mask 1, a mask heater 30 having a triangular planar body is formed on the outside of the nasal capsule portion 3 protruding from the base 2 in a triangular pyramid shape.
It is coated with and heated.

The specific structure of the mask heater 30 will be described with reference to FIG. The size of the mask heater 30 is manufactured according to the shape of the nose wrap portion 3 of the medical mask 1. 36 is a flat plate-shaped heating element mainly made of copper,
Terminals 37, 37 are attached to one end of the heating element 36, and lead wires 38, 38 are connected to the terminals 37, 37. The heating element 36 to which the lead wires 38, 38 are connected is built in a heat conductive synthetic resin case 35, and the outside of the case 35 is covered with a synthetic resin insulator 34. When the lead wires 38, 38 are connected to a power source, the heating element 36 generates heat. This planar mask heater 30 is characterized in that it has a large heat generation area. By connecting the lead wires 38, 38 to a power source, it is possible to heat the entire outer side of the nasal capsule portion 3 in a short time.

The front view in FIG. 7 and the perspective view in FIG. 8 relate to still another embodiment of the medical mask 1, and those shown in FIGS. 1 and 3 are apnea syndromes. While the purpose of the invention is to cover only the nose of the patient, the medical mask 1 is intended to cover both the nose and mouth of the patient. Therefore, in the medical mask 1, the tubular mask heater 20 or the planar mask heater 30 as described above is provided so as to cover not only the nasal capsule portion 3 but also the mouth portion. The other points are the same as those shown in FIGS. The medical mask 1 having such a structure is worn so as to cover both the nose and the mouth of the patient as shown in FIG.

[0023]

As described above, the present invention is configured so that there is no temperature difference between the temperature of oxygen inside the medical mask and the temperature of the atmosphere outside the medical mask. As a result, dew condensation does not occur inside the medical mask even during the winter. Therefore, according to the present invention, patients in the apnea group do not feel discomfort due to dew drops,
The effect is that you can always sleep well. Further, since it is not necessary to remove the dew drops that have accumulated inside the medical mask one by one, there is an effect that the burden on a nurse or the like can be reduced.
