When the floating ball 130 reaches the top of the plurality of ventilation sleeves 110 in the expanded state, it indicates that one exhalation or inhalation training has been completed; the top surface of the air regulating plug 140 is symmetrically provided with an exhalation hole 141 so that the gas inside the ventilation sleeve 110 can be discharged in time;

[0039] The ventilation sleeve 110 is made of PP or PA material to form a transparent cylindrical structure, and the specifications of several ventilation sleeves 110 are in a nesting doll-like matching size; a support ring 122 is fixed between the top ends of a pair of tubes 120, and the support ring 122 is sleeved and matched with the top end of the ventilation sleeve 110 located on the outermost side.

[0040] Furthermore, a plurality of telescopic tubes 123 are sleeved inside the trustee 120 in an inner and outer connection, and a collar 124 is fixed between the top ends of each pair of telescopic tubes 123, and the collar 124 is sleeved and matched with the ventilation sleeve 110 of a size that matches the collar 124. An annular protrusion is provided on the inner wall of the top end of the trustee 120, and an annular protrusion is provided on the inner wall of the top end of the telescopic tube 123, and an annular protrusion is also provided on the outer wall of the bottom end, thereby forming a limiting structure, so that the trustee 120 and the telescopic tube 123 will not slip when they are stretched apart, and the adjacent two telescopic tubes 123 will not slip when they are stretched apart.

[0041] Specifically, the breathing mouthpiece 200 includes a mouth mask 210 movably connected to the bottom end of the outermost ventilation sleeve 110, a nose mask 220 arranged on the outer side wall of the mouth mask 210, and an inhalation tube 230 connected between the nose mask 220 and the air regulating plug 140; the nose mask 220 and the mouth mask 210 are an integrally formed structure and the interior thereof is a hollow structure, the connection ends of the nose mask 220 and the mouth mask 210 are open and can cover the mouth and nose at the same time; the connection ends of the mouth mask 210 and the nose mask 220 are clamped with a sealing cover 250, so that dust and bacteria are not allowed to enter when not in use, thereby playing a protective role; the inner walls of the mouth mask 210 and the nose mask 220 are both bonded with silicone pads to seal the face;

[0042] An exhalation channel is formed between the mouth mask 210 and the ventilation sleeves 110 to blow up the float 130, i.e., exhalation training is performed; an inhalation channel is formed between the nose mask 220, the inhalation tube 230 and the ventilation sleeves 110 to suck up the float 130, i.e., inhalation training is performed.

[0043] Furthermore, a support sleeve 121 is fixedly provided at the bottom end of the outermost ventilation sleeve 110, which plays a role of blocking and supporting the floating ball 130; and the bottom ends of a pair of support tubes 120 are fixedly connected to the top surface of the support sleeve 121 by bolts; the mouth cover 210 is trumpet-shaped and its small diameter end is connected to an air outlet pipe 211, and the air outlet pipe 211 is sleeved with the support sleeve 121, so that the large diameter end of the mouth cover 210 faces downward and stands firmly on the table;

[0044] The inner wall of the bottom end of the support sleeve 121 is sleeved with a connecting sleeve 240, and a retractable connecting tube 241 is sleeved and bonded to the inner wall of the connecting sleeve 240. The lower end of the connecting tube 241 is sleeved and sealed with the inner wall of the outlet pipe 211. The connecting tube 241 is a corrugated plastic tube that can be retracted and bent so that it can be used to align with the mouth and nose after the mouth mask 210 is removed.

[0045] Furthermore, the nasal mask 220 is an arched shell and is connected to an air inlet pipe 221 on its side facing the air outlet pipe 211. An air inlet hole 142 is provided at the edge of the top surface of the air regulating plug 140 and between a pair of exhalation holes 141. The upper and lower ends of the air inlet pipe 230 are respectively sleeved and sealed with the air inlet hole 142 and the air inlet pipe 221.

[0046] Furthermore, a through hole is opened in the center of the air regulating plug 140 and an air regulating valve 150 is sleeved in the through hole. The air regulating valve 150 is a flat cylinder and its height is greater than the thickness of the air regulating plug 140. Hole plugs 151 are symmetrically provided on both sides of the upper end of the air regulating valve 150, and the hole plugs 151 are plugged and slidably connected with the exhalation hole 141. The height of the hole plug 151 is less than the difference in axial height between the air regulating valve 150 and the air regulating plug 140; so that when the air regulating valve 150 is pushed up and cannot move by the float 130, the hole plug 151 has been moved out of the exhalation hole 141, and the exhalation hole 141 is opened to exhaust air.

[0047] When the lung rehabilitation breathing training device for thoracic surgery patients of the present invention is used, the plurality of ventilation sleeves 110 are first pulled up vertically and unfolded, and the size of the unfolded air volume space is selected according to the different stages of the patient's postoperative period. For example, a small air volume space is selected at the initial stage after the operation so that the patient needs less air volume to complete the breathing training. As time goes by, the air volume space is increased so as to enhance the strength of the breathing effect.

[0048] Then, the mouthpiece 200 is removed from the bottom of the support sleeve 121, turned to face the face and cover the corresponding mouth and nose to perform alternating breathing training; when exhaling into the ventilation sleeves 110, the float 130 is placed on the top and pushes up the air regulating valve 150, and then the exhalation is continued to avoid the air from being unable to be discharged; then, when switching to inhalation, the float 130 loses its push force and falls to the bottom of the ventilation sleeve 110. After the air inside the ventilation sleeves 110 is inhaled, the float 130 is placed on the top and pushes up the air regulating valve 150, and then the outside air is inhaled, avoiding the inhalation being blocked and allowing the inhalation of new air; such inhalation and exhalation training speeds up the training speed and saves time;

[0049] After the training, the mouth mask 210 and the nose mask 220 are cleaned and wiped, and then the ventilation sleeves 110 are folded and the breathing mouthpiece 200 and the supporting sleeve 121 are connected and placed on the desktop as a whole, so that the overall space is small and it is easy to carry and store.
