BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic illustration of a preferred embodiment of a multi-segment gas volume Assisted Breathing Apparatus of the present invention.

Fig. 2 is an enlarged schematic view showing the respiratory cover of the auxiliary breathing apparatus in which the multi-stage gas amount is adjusted in Fig. 1.

Figures 3 and 4 are enlarged cross-sectional views, respectively, of the auxiliary breathing apparatus for multi-stage gas volume adjustment in Figure 1.

Hereinafter, the components of the auxiliary breathing apparatus for multi-stage gas amount adjustment of the present invention and the achievement of efficacy will be described with reference to the preferred embodiments of the drawings. However, the components, dimensions, and appearance of the multi-stage gas amount-adjusted auxiliary breathing apparatus in each of the drawings are merely illustrative of the technical features of the present invention and are not intended to limit the present invention.

As shown in Fig. 1, the multi-stage gas amount adjusting auxiliary breathing apparatus of the present invention 10 includes a flexible bladder 11, a respirator 13, and a gas regulator 15.

The flexible airbag 11 has a gas storage space for storing a gas. Gas usually refers to oxygen. The flexible airbag 11 is preferably made of polyvinyl chloride (PVC), plastic (PSF) or silicone rubber, but is not limited thereto. In this embodiment, the flexible airbag 11 can store 2700 ml of oxygen, and the 2700 ml of oxygen is a predetermined amount of gas that the flexible bladder 11 can store oxygen, but the predetermined amount of gas is not limited to 2700 ml.

As shown in FIG. 2, the respiratory cover 13 has a connecting tube 131, a first flexible cover 133 and a second flexible cover 135. The inner wall 137 of the connecting pipe 131 forms a gas passage 139. The first flexible body 133 and the second flexible body 135 extend from the outer wall 141 of the connecting tube 131, respectively. The second flexible cover 135 is seated in the first flexible cover 133. The respiratory mask 13 is preferably made of a silicone material, but is not limited thereto. The size of the first flexible cover 133 is suitable for adults and children, and the second flexible cover 135 is suitable for infants.

In particular, the first flexible cover 133 has a first annular bottom edge 1331, and the second flexible cover 135 has a second annular bottom edge 1351. The position of the first annular bottom edge 1331 is lower than the first The position of the second annular bottom edge 1351 will be described later.

As shown in FIG. 3, the gas regulator 15 is connected to the connecting tube 131 of the flexible airbag 11 and the respiratory cover 13, and has an air inlet 151, an air outlet 153, and a multi-stage adjustment unit 155. The intake port 151 communicates with the air storage space of the flexible airbag 11. The air outlet 153 communicates with the gas passage 139 of the connection pipe 131. The multi-stage adjustment unit 155 is for controlling the amount of gas passing through the gas passage 139 in the gas storage space.

In this embodiment, the multi-stage adjustment unit 155 is used to switch between three positions S1, S2, S3, which correspond to different output gas quantities. The position S1 indicates that it is suitable for an adult, and the oxygen output amount (ie, the amount of output gas) for an adult is 800-1,450 ml. The position S2 indicates that it is suitable for children, and the amount of oxygen pressure (ie, the amount of output gas) applied to the child is 350 ml. Position S3 indicates that it is suitable for infants, and the amount of oxygen output (ie, the amount of output gas) applied to the infant is 100 ml. It can be seen that the predetermined gas system of the flexible airbag 11 is larger than the output gas amount.

The gas regulator 15 also has a deflation unit 157 for discharging excess gas. The multi-stage adjustment unit 155 is switched to the position S2 as an example. Although the flexible airbag 11 stores 2700 ml of oxygen, when the flexible airbag 11 is pressed once, the air can be flexed. The oxygen in the bladder 11 is caused to flow to the gas regulator 15. At this time, if the multi-stage adjusting unit 155 is switched at the position S2, it means that only 350 ml of oxygen can enter the breathing mask 13, and the remaining oxygen is from the deflation unit. 157 is discharged to avoid excessive or too little oxygen output. Similarly, when the multi-stage adjustment unit 155 is switched at the position S1, 800 ml to 1350 ml of oxygen enters the respirator 13, and the remaining oxygen is also discharged from the deflation unit 157; when the multi-stage adjustment unit 155 is switched at the position S3, there is 100 ml of oxygen enters the breathing mask 13, and the remaining oxygen is also discharged from the deflation unit 157.

In addition, since the position of the first annular bottom edge 1331 is lower than the position of the second annular bottom edge 1351, when the respiratory cover 13 is covered by the mouth or nose of an adult or a child, the second flexible cover 135 is not Will touch the mouth and nose of adults or children.

As shown in FIG. 4, the first flexible cover 133 is suitable for adults and children, and the second flexible cover 135 is required for the baby. Therefore, when the second flexible cover 135 is to be used, The first flexible cover 133 can be everted by the material property of the first flexible cover 133 itself, and the second flexible cover 135 can be exposed, which is suitable for the baby. It is indicated that when the second flexible cover 135 is applied, the multi-stage adjustment unit 155 should be switched at the position S3. If applied to an adult, the first flexible cover 133 is used and the multi-stage adjustment unit 155 should be switched at position S1.

Compared with the prior art, the multi-segment gas volume adjusting auxiliary breathing apparatus 10 of the present invention can be applied to adults, children and infants, and does not need to carry multiple groups as in the prior art. Therefore, the present invention does not increase firefighters. Or the burden of medical staff attending.

Finally, it is emphasized that the constituent elements disclosed in the foregoing embodiments are merely illustrative and are not intended to limit the scope of the present invention, and alternatives or variations of other equivalent elements should also be the scope of the patent application of the present application.
