The invention discloses a device for bi-phase forming of exogenous positive end-expiratory pressure through oxygen driven inhalation. The device comprises an oxygen driven inhalation mechanism, a T-shaped joint and a mouthpiece, wherein an inspiration one-way valve is arranged in a first opening; and the mouthpiece is connected with a second opening of the T-shaped joint. Therefore, atomizing gas with inspiration oxygen helps dilute secretion of the air passage and improve the blood oxygen saturation, blood oxygen improvement facilitates improving expiratory dyspnea of patients and active cough to remove secretion of the air passage, and meanwhile, the exogenous positive end-expiratory pressure resists endogenous positive end-expiratory pressure of a COPD (Chronic Obstructive Pulmonary Disease) patient so as to be favorable for reducing the concentration of carbon dioxide in blood. Accordingly, not only is secretion of the air passage removed, but also carbon dioxide retention caused by oxygen inhalation is prevented.

The invention relates to the technical field of medical devices, in particular to a clinical pulmonary rehabilitation exercise device in respiratory medicine, which includes a substrate, a backboard, an elastic air bag, a resistance blowing device, an inflatable cylinder, a hand-supported telescopic rod, a filter head, a mask, a puller Stretching spring, the middle part of the front outer wall of the base plate is fixedly connected with an inflatable cylinder, and the upper outer wall of the middle part of the inflatable cylinder is fixedly connected with a resistance blowing device, and the resistance blowing device includes a resistance air cylinder, an exhaust pipe, a thrust Piston, support rod, resistance piston. The structure design of the invention is reasonable. When inhaling, the arms can be stretched out to expand the chest. When exhaling, the inflatable cylinder can inflate the resistance air cylinder, so that the resistance piston and thrust piston can move up in the resistance air cylinder to exert resistance to exhalation, and at the same time press down The column will press down on the back panel, so that the elastic airbag can press down and massage the chest, so that the air can be exhaled. It is easy to use, can increase the strength of the respiratory muscles, increase the breathing range, and improve the effect of lung rehabilitation exercises.

The invention discloses a TCPC (total cavopulmonary connection) stent. The TCPC stent comprises an artificial blood vessel, a blocking stent and a covered stent. The blocking stent and the covered stent are made of memory alloy. A flow guide hole is communicated with the wall of the artificial blood vessel. The blocking stent is in the shape of a tube with openings at two ends, and is provided with a flow blocking film internally. The flow blocking film is used for sealing the blocking stent. The blocking stent can be embedded in the artificial blood vessel. The coated stent is in the shape of a tube with openings at two ends in a natural state, and the outer diameter of the coated stent is larger than or equal to the inner diameter of the artificial blood vessel in that state. After being compressed, the coated stent can be paced in the artificial blood vessel and can be penetratingly arranged in the blocking stent. When the coated stent swells to recover to the natural state, the outer wall of the coated stent can be attached to the partial inner wall of the artificial blood vessel and the inner wall of the blocking stent tightly so as to seal the flow guide hole and make the blocking stent through. By the TCPC stent, frequency of conventional staged operations in surgery departments can be reduced, and surgical risk and complication occurrence rate both caused by multiple times of thoracotomies can be lowered.
