[0025] Embodiment One

[0026] At present, in addition to the anesthesia machine or breathing machine with ventilation device, there is a simple balloon respirator. But the balloon respirator is used for assisted ventilation in the case of respiratory arrest or weakening, which needs one hand to hold the ventilation mask and the other hand to pinch the balloon for ventilation, relying on the patient's chest to lift up to observe the effectiveness of ventilation, and the patient cannot use it when breathing.

[0027] The design of the simple breathing device is based on the anesthesia machine circuit, which can manage closed breathing without carbon dioxide absorption device, can observe the condition of spontaneous breathing, can assist ventilation, and can simply adjust the concentration of inhaled oxygen.

[0028] Please refer to Figures 1-5 The disposable simple breathing device of the embodiment can be a balloon structure or an organ type structure (also known as a threaded air bag). It includes a large air bag 2 and a small air bag 4. One side of the large air bag 2 is connected to a first one-way air inlet valve 21, and the other side is connected to a first one-way air outlet valve 25. The end of the first one-way air outlet valve 25 is connected to an air inlet 34. The small air bag 4 is arranged inside the large air bag 2. The top and bottom of the large air bag 2 and the small air bag 4 are connected together. The contraction and expansion of the small air bag 4 can drive the contraction and expansion of the large air bag 2 synchronously. The bottom of the small air bag 4 is connected to a second one-way air inlet valve 41, and the end of the second one-way air inlet valve 41 is connected to an air outlet 35. The air outlet 35 is arranged outside the large air bag 2. The top of the small air bag 4 is connected to a second one-way air outlet valve 42, and the end of the second one-way air outlet valve 42 extends out of the large air bag 2 and the small air bag 4. Oxygen supply and small air bag 4 exhaust are achieved by pressing the large air bag 2 to compress the small air bag 4. By stretching the large air bag 2 to expand the small air bag 4 to absorb the exhaled gas, simple ventilation is achieved.

[0029] Embodiment Two

[0030] Please refer to Figures 1-5, embodiment one is only the most basic state of the breathing device, but direct pressing of the air bag structure can easily cause unevenness in the air bag in hand, reducing the service life of the air bag, and directly stretching the air bag with the hand is not convenient, therefore, on the basis of embodiment one, the device is further optimized in the embodiment. In the embodiment, both the large air bag 2 and the small air bag 4 adopt organ type air bags, the top of the large air bag 2 and the small air bag 4 is connected through the top cover 1, the top of the top cover 1 is connected with the ventilation handle 11 for facilitating manual assisted ventilation; the bottom of the large air bag 2 and the small air bag 4 is connected through the base 3; the base 3 is provided with an arc-shaped air guide groove 31 on the top, the air guide groove 31 is connected with the large air bag 2 on the top, the side of the air guide groove 31 is connected with two groups of air guide pipes 33, the two groups of air guide pipes 33 extend out of the base 3 and are connected with the first one-way air inlet valve 21 and the first one-way air outlet valve 25 respectively; the middle part of the base is provided with an air guide space 32 inside, the air guide space 32 is connected with the second one-way air inlet valve 41 on the bottom of the small air bag 4 on the top, the side of the air guide space 32 is connected with the air guide pipe 33, the end of the air guide pipe 33 extends out of the base 3 and is connected with the air outlet 35. Through the addition of the top cover 1 and the base 3 and the addition of the ventilation handle 11, the large air bag 2 and the small air bag 4 can be stretched and compressed more conveniently, and the ventilation effect is improved.

[0031] In the embodiment, the air guide pipe 33 is further provided with the third one-way air inlet valve 43 at the connection with the air outlet 35 to prevent the backflow of exhaled air. The radius of the large air bag 2 is greater than the outer radius of the arc-shaped air guide groove 31, and the radius of the small air bag 4 is less than the inner radius of the arc-shaped air guide groove 31 to prevent the large air bag 2 and the small air bag 4 from being connected to cause the device to fail. The air inlet 34 and the air outlet 35 are arranged on the same side to facilitate the connection with a breathing mask or an air supply pipe.

[0032] In addition, in order to adjust the oxygen concentration in the air for ventilation, the first one-way air inlet valve 21 is connected with the oxygen adjusting one-way valve 22 at the end, the oxygen adjusting one-way valve 22 is provided with an oxygen inlet 24 and an air inlet 23, the oxygen inlet 24 is connected with an oxygen supply device to provide oxygen.

[0033] Working process:

[0034] The exhaled air of the patient enters the small air bag 4 through the air outlet, and the small air bag 4 is lifted; at the same time, air and oxygen enter the large air bag 2 through the corresponding inlets; when the patient inhales, the large air bag 2 is sunken, and the mixed oxygen and air enter the patient's lungs through the air inlet, and the cycle is repeated. When the patient has poor ventilation, the ventilation handle 11 can be used to press the large air bag 2 to assist ventilation when the patient inhales.

[0035] The above describes the specific implementation of the utility model in combination with the drawings, but is not a limitation on the protection scope of the utility model, various modifications or changes made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
