    摘要： An apparatus, breathing equipment training device, and method for breathing equipment training. The apparatus includes a shell and a diaphragm. The shell includes a first opening and a second opening. The first opening is configured to be inserted into a breathing opening in a mask to form a connection with the breathing opening of the mask. The diaphragm is inside the shell and positioned about the second opening. The diaphragm is configured to impede airflow into the shell through the second opening. The first opening can be defined by a first ellipse insertable into the breathing opening of the mask. The second opening can be defined by a second ellipse through which airflow enters into the shell. A diameter of the second ellipse can be greater than a diameter of the first ellipse.

    摘要： An apparatus and methods for air filtration are disclosed. The apparatus includes a body and first and second replaceable filters. The body of the apparatus further contains an air-exchange assembly and a filter receiver attached to the air exchange assembly. The air-exchange assembly contains an exhaust tube with an open end and a closed end, two wings on opposite sides of the exhaust tube, and an intake check valve and an exhaust check valve inside the exhaust tube. The first replaceable filter surrounds the filter receiver; and the second replaceable filter is inside the filter receiver. Several apertures and the check valves are strategically disposed in the exhaust tube to achieve optimal air filtration and avoid contamination of a user's exhaust.

    摘要： A method of rebreathing for a human, comprising: breathing through a rebreathing device for up to 20 minutes at a time, repeated as needed; wherein said rebreathing device has a form of a) cylindrical form made by rolling a sheet of paper, and able to fit snugly over either the mouth or the nose of a human in need of rebreathing; b) cylindrical form made with a cardboard tube from a toilet paper roll; c) cylindrical form made with a cardboard tube from a paper towel roll; d) cylindrical form made from a washable, re-useable, solid tube and able to fit snugly over either the mouth or the nose; e) rectilinear form made from a paper bag made of absorbent paper, at least 5 inches long [=12.7 cm] for adults, that is modified by i) cutting or tearing horizontally to shorten the bag so the remaining bag is approximately 5 to 7 inches [12.7 to 17.8, cm] tall, and ii) folding over one corner of the rectangular bottom approximately 1 inch [=2.5 cm] and cutting or tearing it off to make a hole approximately 1.5 inch [=3.8 cm] in diameter to allow rebreathing when worn over the nose and mouth; f) triangular form folded in the shape of a mask able to cover both nose and mouth made from i) a sheet of paper size 8.5×11 inches [=21.6×28 cm], A-10, or any larger sheet of newspaper folded down to this size, or made by folding a foil-lined snack-food bag of approximately 6×10 inches [=15.2×25.4 cm]; or g) conical form made from a paper, foam or plastic disposable cup, into which a hole is made in the bottom about 1 inch [=2.5 cm], which need not need to be centered, so that the original cup opening may be placed over the nose and mouth and pushed lightly against the face so that it forms a snug seal all around.

    摘要翻译： 一种对人类进行呼吸的方法，包括：一次呼吸通过反复呼吸达20分钟，根据需要重复; 其中所述再呼吸装置具有以下形式：a）通过滚动一张纸而制成的圆柱形形状，并且能够紧密地贴合在需要再呼吸的人的嘴或鼻上; b）由卫生纸滚筒用纸板管制成的圆柱形; c）用纸巾卷起的纸板管制成的圆柱形; d）由可洗涤，可重复使用的实心管制成的圆柱形形状，能够紧贴在嘴或鼻子上; e）由成人的至少5英寸长= 12.7厘米的由吸收纸制成的纸袋制成的直线形式，其通过i）水平切割或撕裂以缩短袋以使剩余袋约为5至 7英寸[= 12,7至17.8厘米]高，并且ii）在大约1英寸[= 2.5厘米]的矩形底部的一个角上折叠，并切割或撕开以形成大约1.5英寸的孔[= 3,8厘米]，以便在鼻子和嘴巴上穿戴时可以重新呼吸; f）三角形折叠成能够覆盖鼻子和口腔的形状的三角形形状，其由i）一张尺寸为8.5×11英寸[= 21,6×28cm]的纸张，A- 10或任何较大的报纸 折叠成这种尺寸，或通过折叠约6×10英寸[= 15,2×25,4厘米]的带箔衬里的小吃食品袋制成; 或g）由纸，泡沫或塑料一次性杯制成的圆锥形，其中在底部制成大约1英寸[= 2.5cm]的孔，其不需要居中，使得原始杯开口 可以放在鼻子和嘴巴上，轻轻地推着脸部，使其周围形成一个贴合的密封。
