DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The detailed description and technical content of the invention are described below with reference to the accompanying drawings.

Please refer toFIG.1, the invention provides a mask20, the mask20is mainly used to prevent water from entering a tracheal stoma32opened from a neck31of a tracheostomy patient30when the tracheostomy patient30takes a shower.

Please refer toFIG.1,FIG.2,FIG.3,FIG.4,FIG.5,FIG.6,FIG.7andFIG.8, the mask20comprises a neck hanging part21and a mask body22connected to the neck hanging part21. Wherein, the neck hanging part21is used as a main part for hanging the mask20on the tracheostomy patient30, and the neck hanging part21can be an elastic band, a cord or other devices capable of achieving a same efficacy, the invention does not limit a way of implementing the neck hanging part21.

On the other hand, a concave space221is formed on an inner side of the mask body22, a plurality of air vents222communicating with the concave space221are formed in a lower half of an outer side of the mask body22, and a plurality of inclined retaining walls223are located in the concave space221and respectively connected to a top edge of each of the air vents222. A range of the concave space221is at least big enough such that the tracheal stoma32can be properly positioned therein and a proper breathing space can be reserved. In addition, the plurality of air vents222serve as bridges for the concave space221to communicate with outside, and the plurality of air vents222are not limited to united shape and united size. Please refer toFIG.5andFIG.6, each of the plurality of inclined retaining walls223is respectively connected to the top edge of one of the plurality of air vents222, so that the concave space221can be prevented from being seen when viewed directly through the plurality of air vents222of the mask body22. Thereby, the tracheostomy patient30uses a shower head to take a shower, when shower water sprayed toward the plurality of air vents222caused by careless manipulation, the shower water will not be able to enter the concave space221due to being blocked by the inclined retaining walls223, such that the tracheal stoma32located in the concave space221can be prevented from ingress of water, as shown inFIG.9. In addition, the shower water splashed on the plurality of inclined retaining walls223can be discharged toward the plurality of air vents222, thereby enhancing an effect of preventing water from entering the tracheal stoma32.

Please refer toFIG.1andFIG.8, the inner and outer sides of the mask body22are defined hereinafter in this specification. The inner side refers to a side of the mask body22facing the tracheal stoma32, and the outer side refers to a side of the mask body22that does not face the tracheal stoma32, and the outer side is served as a side of an outer surface when the mask body22is worn. Accordingly, in one embodiment, the outer side of the mask body22includes an arcuate surface224, and the plurality of air vents222cannot be seen when viewing the arcuate surface224from a top edge toward a bottom edge of the mask body22, as shown inFIG.7. Further, water splashed on the arcuate surface224flows toward the bottom edge of the mask body22. Please refer toFIG.4,FIG.5andFIG.8, in one embodiment, a recessed area225is formed in the lower half of the outer side of the mask body22, and the plurality of air vents222are disposed on an edge of the recessed area225. Furthermore, the recessed area225is tapered from the bottom edge toward the top edge of the mask body22. Further, the recessed area225is roughly triangular, and the plurality of air vents222is respectively located on two adjacent sides of the aforementioned triangle.

Please refer toFIG.3andFIG.6again, in one embodiment, the mask body22includes a plurality of inclined drainage walls226located in the concave space221and respectively connected to each of the plurality of air vents222. Further, each of the plurality of inclined drainage walls226is respectively opposite to each of the plurality of inclined retaining walls223. Furthermore, each of the inclined drainage walls226and each of the inclined retaining walls223opposite to each other jointly define a channel227, and the channel227is communicated and tapered toward one of the plurality of air vents222due to configuration of one of the plurality of inclined drainage walls226and one of the plurality of inclined retaining walls223that jointly define the channel227; that is, the channel227is trumpet-shaped, that is, the channel227is gradually expanded from one of the plurality of air vents222, thereby this design is capable of reducing a flow rate of an airflow entering from one of the plurality of air vents222due to the channel227. If water accidentally enters the channel227, this design is also capable of reducing a flow rate of the water, and due to an effect of gravity, the water will flow downward and back to one of the plurality of air vents222, further reducing a possibility of the tracheostomy patient30inhaling water inadvertently. In one embodiment, one end of each of the plurality of inclined drainage walls226not connected to one of the plurality of air vents222is connected to one of the plurality of inclined retaining walls223.

Please refer toFIG.1,FIG.2,FIG.3,FIG.4,FIG.5,FIG.6andFIG.7. In one embodiment, the mask body22includes a skirt228disposed along an edge of the mask body22, the skirt228receives splashed water during showering and prevents water from approaching a position where the mask body22is in contact with a body of the tracheostomy patient30. In another embodiment, when viewed from a side of the mask body22, the skirt228includes a first inclined section229and a second inclined section230connected to the first inclined section229. Wherein, a slope of the second inclined section230is different from that of the first inclined section229. On the other hand, in one embodiment, the mask body22includes a plurality of hanging ears231formed on the skirt228to assemble with the neck hanging part21.

Please refer toFIG.3andFIG.8. In one embodiment, the mask body22includes an airtight ring232disposed along the concave space221. The airtight ring232can be formed integrally with the mask body22or implemented by assembling on the mask body22by another component. If the airtight ring232is another component, the mask body22needs to have an annular assembly portion233formed along the concave space221, the annular assembly portion233needs to be designed to match the airtight ring232, and can be a groove or a rib.

Please refer toFIG.10andFIG.11, a length of each of the plurality of inclined retaining walls223of the invention can be adjusted according to implementation requirements. For example, the mask body22can be provided with the plurality of inclined drainage walls226corresponding to the plurality of inclined retaining walls223, or a length of each of the plurality of inclined drainage walls226can also be adjusted according to a design of the plurality of inclined retaining walls223.
