BEST MODE FOR CARRYING OUT THE INVENTION Exemplary embodiments of the present invention will be described in detail below with reference to the drawings. However, the components described in the following embodiments are merely examples, and the technical scope of the present invention is not limited to them.

[First embodiment]
A mask fixture 100 as a first embodiment of the present invention will be described with reference to FIG. The mask fixture 100 is, for example, a respirator mask, a non-invasive positive pressure ventilation NIPPV (Non-Invasive Positive Pressure Ventilation) mask including CPAP (Continuous Positive Airway Pressure) and BiPAP (Biphasic Positive Airway Pressure), and an N95 mask. It is a fixture for fixing airborne infection control masks, sanitary masks, dust masks, gas masks, etc. to the face. The mask can be a full face mask, a nose-only mask, or a mouth-only mask.

FIG. 1 is an exploded view of the mask fixture 100 before being attached to the mask.

As shown in FIG. 1, the mask fixture 100 includes a central support portion 101 that supports various belts at the center, and belts 102 to 107 connected to the central support portion 101 . The central support portion 101 and the belts 102 to 107 are made of stretchable members having the same or different colors, materials, and materials, and are connected by six seams (butt seams) 108 . The position and presence/absence of seams may be appropriately changed according to the function, design, and productivity required for the fixture. For example, the central support portion 101 and the belts 102 to 107 may be integrally formed without seams in order to improve productivity. Alternatively, the central support portion 101 and the belts 102 to 107 may be connected by fasteners, buttons, hook-like members, iron tapes, or the like instead of seams. By doing so, the belts 102 to 107 can be exchanged according to the user's facial shape and preference. At this time, the color, material, material, and design may be changed for each belt. By nonverbally expressing the difference between the belts in this way, even elderly people with cognitive decline can easily grasp, identify, and recognize how each belt should be connected to the mask without hesitation. become. For example, belts 104 and 105 may be of the same color, belts 106 and 107 may be of the same color, and may be of different colors. Alternatively, belts 105 and 107 may be of the same color and belts 104 and 106 may be of the same color but different colors.

The central support part 101 has arm parts 111 and 112 extending to the left and right in an unworn unfolded state, and covers at least a part of the back neck or the back of the head of the user when worn.

The belts 102 and 103 extend obliquely upward from the arm portions 111 and 112 in the unfolded state. form a circle.

The belts 104 and 105 extend obliquely downward from the arms 111 and 112 in the unfolded state, and when worn, the ends thereof are connected to the top of the mask in front of the user's face.

The belts 106 and 107 extend obliquely downward from the central support portion 101 in the unfolded state, and when worn, the ends thereof are connected to the lower portion of the mask in front of the user's face.

Hook-and-loop fasteners 121-171 known as Velcro (registered trademark) or Velcro (registered trademark) are provided at the ends of the belts 102-107, and are attached to the central support 101 and the surfaces of the belts 102-107 (facing outward when worn). ) are adapted to engage hook-and-loop fasteners 121-171.

FIG. 2 is a diagram for explaining a state in which parts used for fixing the mask to the mask are attached to the mask fixture 100. As shown in FIG.

The ends of the belts 102 and 103 are both passed through an annular member 201 as a connecting member, bent and attached to the surfaces of the belts 102 and 103 with hook-and-loop fasteners 121 and 131 . The belt can be easily attached and detached. The thickness of the belts 102 and 103 may be formed thicker than the connecting member that connects the ends of the belts. The ring 202 is formed in a headband shape by the central support portion 101 including the arm portions 111 and 112 and the belts 102 and 103 so that any head circumference can be perfectly inserted from the front to the back of the user's head. 202 can be adjusted. A pair of belts 102, 103 are connected to each other in an adjustable length, and the user's head is inserted into a loop 202 formed by the central support 101 and the connected pair of belts 102, 103 ( The mask is put on by the user from the head), so that the mask can be attached and fixed to the user's head even when the mask is not attached. In addition, by adopting such a structure of the mask fixing device 100, a mask wearing helper such as a nurse, for example, can use the patient, who is the user, on the bed with the head resting on a pillow, or the head or face. It is possible to easily wear a mask fixture and a mask even in the state of wearing various types of equipment after trauma treatment. In particular, since the mask fixture is made of a stretchable material, it is extremely easy to assist in putting on the mask. In addition, it is possible to reduce the risk of medical accidents (incidents and accidents) such as injury to the skin of the patient who is the user, or getting caught in treatment-related equipment and removing it due to non-elastic materials. If the belts 102 to 107 are made of stretchable members, even if they are hooked on treatment-related equipment, they are less likely to come off the mask.

When worn, the annular member 201 is positioned in the middle or near the middle of the user's forehead. Since the belts 102 and 103 are generally bilaterally symmetrical, the fit is good and the appearance is good.

Since the belts 102 to 107 are all made of stretchable or stretchable materials, their elasticity allows the mask to be brought into close contact with the face with proper pressure. In addition, the entire mask fixture including the central support portion 101 may be elastic.

Attachments 204 to 207 are attached to the ends of the belts 104 to 107 according to the specifications of the mask. Here, hook-type female connectors that are hooked by passing rod-shaped portions protruding from the mask through holes are shown as attachments 204 to 207, but the present invention is not limited to these, and any attachments can be attached. , can be freely changed by the user. For example, the ends of the belts 104 to 107 may be passed through an annular portion provided on the mask side, bent, and fixed with hook-and-loop tape.

3, 4, and 5 show the user 300 wearing only the mask fixture 100 (front view, right side view, and rear view). A ring 202 formed by a central support portion 101 and a pair of belts 102 and 103 connected to each other fits snugly in a ring 201 extending from the top of the head to the back of the head of the user 300, stably supporting the user even when the mask is not attached. worn on the head. Since the elastic member is stably attached to the head, the user can feel no discomfort or less discomfort, or even feel comfortable wearing the elastic member. .

In addition, since the belts 106 and 107 extend obliquely downward from the central support portion 101, they hang neatly along the neck without being twisted. Therefore, even when the user 300 wears only the mask fixing device 100, the user 300 does not feel uncomfortable or worry about the mask fixing device 100 coming off or being displaced. Other tasks can be performed, such as eye and nose drops, oral and perioral care (e.g., brushing teeth and shaving). In addition, by changing the material and color of the front and back of the mask fixture as a whole or part of it, or by using letters, marks, or illustrations, it is possible to make it easier to understand the front and back when wearing the fixture. The tactile sense of recognition may be improved.

FIG. 6 is a front view showing a state in which a respirator mask 600 is attached only to the belt 106 on one side of the mask fixture 100. FIG. In this way, the mask retainer 100 can remain attached even when the mask 600 is removed from the face. Therefore, the user maintains the mask hygienically attached to the mask fixing device in a medical field such as a hospital, or in a place such as a construction site where putting the mask on is unsanitary. It is possible.

Since only the fixture 100 can be firmly attached to the head in this manner, the belts 104 to 107 can be slowly attached to the mask one by one after the mask fixture 100 is worn over the head. Therefore, even if the user is not dexterous with his/her hands, the mask can be securely attached to the face by one person. Conversely, by using a stretchable material for the whole or part of the fixture, it is possible to cover the mask fixture 100 with the mask set in advance. A user or a mask-wearing helper such as a nurse can appropriately select a mask-wearing method that is easy for him/herself.

Conventional mask fixtures have no elasticity on the whole, or there are parts that do not have elasticity, so the mask does not fit the face in places, the mask floats, and there is a gap between the mask and the skin. Therefore, a situation could arise in which airtightness could not be ensured. In other words, it may cause leaks during artificial respiration, or cause dust to be inhaled into the lungs when the dust mask does not work. However, the mask fixing device 100 according to the present embodiment fits the entire head due to its structure or elasticity, so that it is possible to ensure the sealability of the mask and further provide comfort to the user. In particular, since the connection points of the belts 102 and 103 are not on the back of the head or the top of the head but on the frontal side of the head, the belts 102 and 103 are sandwiched between the central support portion 101 located on the back of the neck and are unlikely to slip off. Due to such good supportability, the user can attach the fixture in advance and then connect the mask without feeling any stress. Such a mounting method can be performed without difficulty.

7 and 8 are diagrams showing a state in which the bellows mask 700 attached to the mask fixture 100 is worn.

The bellows mask 700 has a bellows part 701 that follows the shape of the user's face and can change the internal volume according to breathing. The bellows portion 701 is made of soft resin. The bellows mask 700 has a front plate 702 made of transparent hard resin. The front plate 702 has a curved shape like a turtle shell. The user's mouth can be clearly seen through the front plate 702 .

Front plate 702 is provided with four pins 721-724, which are capable of engaging fittings 204-207, respectively. The pin 721 and the fixture 204 are colored the same color (eg, red), the pin 722 and the fixture 205 are colored the same color (eg, blue), the pin 723 and the fixture 206 are colored the same color (eg, green), and the pin 724 is colored the same color (eg, green). If the belt and the fitting 207 are colored in the same color (for example, yellow), the corresponding relationship between the belt and the pin becomes clear, and it becomes possible to reduce installation mistakes. In other words, the fixtures at the four locations may all be of different colors or the like to correspond to the colors of the four pins or the like. As described above, the color, material, material, and design of each belt can be made to correspond to each pin and fixture. For example, even if a combination is selected to identify the upper half (corresponding to pins 721 and 722), the lower half (corresponding to pins 723 and 724), or the left and right (pins 722 and 724 and pins 721 and 723), The belt can be easily attached to the mask, and the combination method can be freely selected. In addition to the belts 102 to 107, the pins 721 to 724 of the bellows mask or the attachments 204 to 207 may be made individually changeable.

FIG. 9 is a view of only the bellows mask 700 viewed obliquely from above (the position of the user's eyes). A bellows portion 701 of the bellows mask 700 is attached with band-shaped portions 901 to 906 . Although there are three strips on the right side and three strips on the left side, the number of strips 901 to 906 is not limited to this. The band-shaped portions 901 to 906 are members extending in the front-rear direction along the bellows portion 701, respectively. By forming the band-shaped portions 901 to 906 from a resin having the same rigidity as that of the bellows portion 701 or a resin having a high rigidity, the front-rear stretchability of the bellows portion 701 can be adjusted according to the number of the band-shaped portions 901 to 906 attached to the bellows portion 701. It can be changed depending on the point where it abuts on. The cross-sectional shape (width, thickness, height) may be changed depending on the positions of the band-shaped portions 901-906. By providing the band-shaped portions 901 to 906, it is possible to firmly attach the end surfaces 911 and 912 of the bellows portion 701 to the skin on both sides of the nose (the maxillary bone portion under the eyes). The band-shaped portions 901 to 906 may be formed integrally with the bellows portion 701, or may be formed separately and attached later.

Although FIG. 9 shows only the belt-like portions 901 to 906 attached to the upper surface of the bellows portion 701, the lower surface of the bellows portion 701 may also be attached with a belt-like portion made of a similar material. For example, if four strips on each side of the bellows part 701 are attached to the lower surface of the bellows part 701 with a greater space than the left and right strips on the upper surface, the bellows part 701 can be brought into close contact with the user's cheek. Become. By changing the number and width of the band-shaped portions in this way, it is possible to easily recognize the top and bottom of the mask. The color, material, and design of each strip may be changed as appropriate.

The face-side (rear) end of the bellows portion 701 is folded inward, and a concave portion 913 is formed along the shape of the nose. This makes it possible to increase the contact area with the face and prevent leakage. Further, by forming wide (convex) end surfaces 911 and 912 on both sides of the concave portion 913, it is possible to fit more variations in the shape of the root of the nose.

In the case of the bellows mask 700, since the mask fixture 100 expands and contracts along with the expansion and contraction, the mask is always pressed against the face with a constant pressure, and air leakage can be prevented. Furthermore, it is possible to prevent skin disorders such as pressure ulcers and pressure injuries caused by conventional mask fixtures with poor overall elasticity.
