[0009]FIG. 3 shows schematically the perspective view of the ventilation mask according to the present invention. [0010]FIG. 4 shows the exploded view of the ventilation mask according to the present invention. [0011]FIG. 5 shows schematically that a tube type is formed first, the middle part of the tube is formed into an “S” shape. [0012]FIG. 6 shows schematically that a toroidal tube is formed with the tube type FIG. 5.
DETAILED DESCRIPTION OF THE INVENTION [0013] As shown in FIGS. 3 and 4, the ventilation mask 30 according to the present invention comprises: [0014] an upper hood 40 made of hard polycabonate or polysulfone, having an excellent transparency and can be disinfected in high temperature for repeated use, a connecting tube 41 being provided thereof for input oxygen, several punctures 42 being provided suitably along the lower peripheral thereof. [0015] a toroidal tube 50 made of soft silicone, first to form a tube type (see FIG. 5), the middle part of the tube is formed into an “S” shape, whenever the lower part of the “S” is turned upwardly and inwardly, the “S” part will form the toroidal tube 50 (see FIG. 6). The toroidal tube 50 can be injected with air, so as to conform the face of the patient. [0016] The upper part 51 and the lower part 52 of the tube type are provided with punctures 511, 521 respectively. After the upper part 51 and the lower part 52 are attached and bound together, an assembly member 60 is used to penetrate through the puncture 42 of the upper hood 40 and the punctures 511, 521 on the upper part 51 and the lower part 52 of the tube type, therefore to form a ventilation mask 30. [0017] A connecting tube 513 is provided suitably at the “S” part for injecting air into the toroidal tube 50, so that the toroidal tube 50 can conform to the face of the patient. [0018] The assembly member 60 is used to combine the toroidal tube 50 and the upper hood 40 to form the ventilation mask 30. As shown in FIG. 4, the assembly member 60 is a button type, comprising a male button 61 and a female button 62. Each of the male button 61 and the female button 62 has a round surface 611, 621 respectively. A round pillar 612 and a round cylinder 622 are each provided at the center of the round surfaces 611, 621 respectively. When the round cylinder 622 penetrates through the puncture 42 of the upper hood 40 and the punctures 511, 521 on the upper part 51 and the lower part 52 of the tube type, and then the round pillar 612 of the male button 61 is plugged into the round cylinder 622, the ventilation mask 30 is therefore suitably assembled. [0019] The round pillar 612 and the round cylinder 622 can be designed with screw thread, and the round surface 611 has a groove. When we loosen the assembly member 60 to separate the upper hood 40 and the toroidal tube 50, the toroidal tube 50 can be replaced or be disinfected for repeated use. [0020] The advantages of the ventilation mask according to the present invention are being comfortable, excellent air tightness, and transparency. And the toroidal tube can be disassembled to disinfect for repeated use or for replacement. The upper hood does not have to be replaced, so the garbage is reduced. [0021] The scope of the present invention depends only upon the following claims, and is not limited by the above embodiment.
