[0013] The beneficial effects of the present invention are: (1) the present invention provides effective respiratory support for patients by controlling the air pressure in the inner cavity of each shell and the expansion and contraction of each airbag through air pressure drive.

When the air pressure in the inner cavity of each shell decreases, the gap between the pressure-dividing suction cup membrane and the shell decreases, while the gap between the pressure-dividing suction cup membrane and the patient's chest cavity increases, so that the air pressure outside the patient's chest cavity is increased. The air pressure in the inner cavity of each shell increases, and the air pressure in the inner cavity of each shell increases. This reasonable design structure effectively avoids the increase or decrease of the air pressure in the inner cavity of each shell from directly affecting the outside of the patient's chest cavity, reduces the air pressure shock load on the patient's chest cavity, provides effective protection for the patient, and proves the reliability and safety of the present invention. (3) The present invention reasonably designs the scale of contraction and expansion of pneumatic artificial muscles by imitating the principles of traditional Chinese medicine massage. The pneumatic artificial muscles include three annular artificial muscles arranged in parallel. When the pneumatic artificial muscles are inflated, the radial expansion of the bottom artificial muscles is the largest, and the radial expansion of the top artificial muscles is the smallest, so that the abdominal fixation plate and the abdominal drive airbag are in an oblique upward posture, which is conducive to adapting to the human body's breathing position and more effectively assisting and adjusting the patient's breathing state.

DETAILED DESCRIPTION
[0015] In order to provide a further understanding of the purpose, structure, features and functions of the present invention, the following detailed description is given in conjunction with the embodiments.
[0016] like Figure 1-Figure 4 A partitioned air pressure driven wearable breathing assistance robot shown in the figure comprises an upper chest shell 1, an upper chest shell soft package 2 and a suspension belt 3, wherein the upper chest shell soft package 2 is adhered to the edge of the upper chest shell 1; the suspension belt 3 is connected to the upper chest shell 1; an upper chest pressure suction cup membrane 15 is also arranged inside the upper chest shell 1, and the upper chest pressure suction cup membrane 15 is connected to the inner wall of the upper chest shell 1, and the upper chest pressure suction cup membrane 15 encapsulates the inner cavity of the entire upper chest shell 1; A right chest lower shell 6 and a left chest lower shell 7 are arranged below the chest upper shell 1, a right chest lower shell soft package 10 is adhered to the edge of the right chest lower shell 6, a left chest lower shell soft package 9 is adhered to the edge of the left chest lower shell 7, and two ends of the left chest lower shell soft package 9 are respectively connected to the two ends of the right chest lower shell soft package 10; a left chest lower partial pressure suction cup membrane 16 and a right chest lower partial pressure suction cup membrane 17 are respectively arranged inside the left chest lower shell 7 and the right chest lower shell 6, the left chest lower partial pressure suction cup membrane 16 and the right chest lower partial pressure suction cup membrane 17 are respectively connected to the inner walls of the left chest lower shell 7 and the right chest lower shell 6, and the left chest lower partial pressure suction cup membrane 16 and the right chest lower partial pressure suction cup membrane 17 respectively encapsulate the entire inner cavity of the left chest lower shell 7 and the right chest lower shell 6; The left chest cavity lower shell 7 is connected to the chest cavity upper shell 1 through the left lateral drive airbag 5; the right chest cavity lower shell 6 is connected to the chest cavity upper shell 1 through the right lateral drive airbag 4; the left chest cavity lower shell 7 and the right chest cavity lower shell 6 are connected through the middle drive airbag 8; The lower part of the left outer surface of the upper chest cavity shell 1 and the upper part of the outer surface of the lower left chest cavity shell 7 are both provided with connecting grooves, and the left lateral driving airbag 5 is located in the connecting groove. The end surface of the connecting groove is perpendicular to the movement lifting direction of the left lateral driving airbag 5 when it is inflated, and the two ends of the left lateral driving airbag 5 are respectively bonded and fixed to the end surfaces of the two connecting grooves on the upper chest cavity shell 1 and the lower left chest cavity shell 7.
[0017] The lower right side outer surface of the upper chest cavity shell 1 and the upper outer surface of the right chest cavity lower shell 6 are both provided with connecting grooves, and the right lateral driving airbag 4 is located in the connecting groove. The end face of the connecting groove is perpendicular to the movement lifting direction of the right lateral driving airbag 4 when it is inflated, and the two ends of the right lateral driving airbag 4 are respectively bonded and fixed to the end faces of the two connecting grooves on the upper chest cavity shell 1 and the right chest cavity lower shell 6.
[0018] A connecting groove is provided in the middle of the right side outer surface of the left chest cavity lower shell 7 and the middle of the left side outer surface of the right chest cavity lower shell 6. The middle driving airbag 8 is located in the connecting groove. The end surface of the connecting groove is perpendicular to the movement lifting direction of the middle driving airbag 8 when it is inflated. The two ends of the middle driving airbag 8 are respectively bonded and fixed to the end surfaces of the two connecting grooves on the left chest cavity lower shell 7 and the right chest cavity lower shell 6.
[0019] like Figure 3 A partitioned pneumatically driven wearable breathing-assisting robot is shown, which also includes an abdominal structure, which includes an abdominal-driven airbag 11 and a pneumatic artificial muscle 12. The pneumatic artificial muscle 12 is located below the left chest cavity lower shell 7 and the right chest cavity lower shell 6; an elastic fixing belt 13 is wrapped around the surface of the pneumatic artificial muscle 12, and the elastic fixing belt 13 is attached to the surface of the pneumatic artificial muscle 12 and is located in the lateral middle position of the pneumatic artificial muscle 12. The pneumatic artificial muscle 12 surrounds and fixes an abdominal fixing plate 14 inside the pneumatic artificial muscle 12, and the rear end of the abdominal-driven airbag 11 passes through the elastic fixing belt 13 to be connected and fixed to the abdominal fixing plate 14.
[0020] The pneumatic artificial muscle 12 includes three annular artificial muscles, which are arranged in parallel and kept in an upper and lower arrangement at a fixed distance. The pneumatic artificial muscle 12 is made of a woven sleeve and a latex tube. When the pneumatic artificial muscle 12 is inflated, the pneumatic artificial muscle 12 shortens axially and expands radially. The artificial muscles in the bottom layer expand the most, and the artificial muscles in the top layer expand the least. This makes the abdominal fixation plate 14 and the abdominal drive airbag 11 present an oblique upward posture when the pneumatic artificial muscle 12 is inflated, which is conducive to adapting to the human body's breathing position and more effectively assisting and adjusting the patient's breathing state.
[0021] The upper chest shell 1, the left chest lower shell 7 and the right chest lower shell 6 are all provided with connection holes, and the connection holes connect the air pump with the inner cavity of the upper chest shell 1, the left chest lower shell 7 and the right chest lower shell 6 through tracheas.
[0022] The upper chest shell 1, the left chest lower shell 7 and the right chest lower shell 6 are all made of hard material such as photosensitive resin; the upper chest shell soft package 2, the left chest lower shell soft package 9 and the right chest lower shell soft package 10 are all made of polyurethane foam sponge.
[0023] The abdominal driving airbag 11 and the abdominal fixing plate 14 are both in the shape of a trapezoid that is narrow at the top and wide at the bottom. The left lateral driving airbag 5, the right lateral driving airbag 4 and the middle driving airbag 8 are all cylindrical and the circular area is smaller than the area of the trapezoidal shape of the abdominal driving airbag 11 and the abdominal fixing plate 14. The trapezoidal shape with a larger area can more effectively support the abdominal position of the human body, thereby improving the applicability of the present invention.
[0024] Working principle: The air pump controls the air pressure of the upper chest shell 1, the lower left chest shell 7 and the lower right chest shell 6 through the trachea through the connection holes on each shell, drives the patient to breathe, and the right lateral drive airbag 4, the left lateral drive airbag 5 and the abdominal drive airbag 11 are extended to assist the expansion and contraction of the patient's chest and abdomen. When the air pressure inside each shell is controlled to decrease and each airbag is extended, the patient is actively driven to inhale. When the air pressure inside each shell is controlled to increase and each airbag is contracted, the patient is actively driven to exhale. Each part of the pressure-dividing suction cup membrane wraps the inner cavity of the entire upper chest shell 1, the lower left chest shell 7 and the lower right chest shell 6. When the air pressure in the inner cavity of each shell decreases, the gap between the pressure-dividing suction cup membrane and the shell decreases, while the gap between the pressure-dividing suction cup membrane and the patient's chest increases, so that the air pressure outside the patient's chest decreases, thereby driving the patient to inhale. The same applies when the air pressure in the inner cavity of each shell increases. At the same time, when the air pressure inside the pneumatic artificial muscle 12 is controlled to increase, the pneumatic artificial muscle expands radially and shortens axially. The bottom annular artificial muscle expands the most, while the top annular artificial muscle expands the least, causing the abdominal fixation plate 14 and the abdominal drive airbag 11 to be in an oblique upward posture, allowing the patient to receive more effective respiratory treatment.
[0025] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention are all within the scope of patent protection of the present invention.
