Problems solved by technology

The existing technology deals with patients with hypoxia and dyspnea, mainly from the aspects of breathing power and gas supply quality and quantity, but it has little effect on patients with gas exchange disorders caused by the structure and function of the lungs.

Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention will be described in further detail:

[0023] Such as force 1, figure 2 As shown, the lung sac 1 is a long cylindrical flexible sac made of elastic and shaped supporting material, and a diaphragm 4 is arranged in the middle of the sac to separate the air sac 2 and the oxygen inhalation 3 . Venous blood inlet 5 and exhaust port 8 are set at the beginning of lung sac cavity 1. After venous blood enters lung sac cavity 1, it will be shunted into capillary bundles composed of many capillaries 7. The membrane is fabricated as side-by-side capillaries with elastic support function. The capillary 7 passes through the diaphragm 4 and enters the oxygen inhalation chamber 3 from the air chamber 2 . The capillaries 7 converge at the end of the pulmonary sac cavity 1 and are discharged back through the arterial blood outlet 6 . An oxygen input port 9 is arranged on the end of the lung cavity 1 . A negative p...

Abstract

The invention relates to a cardiopulmonary bypass artificial lung, characterized by leading venous blood in large superficial veins of a human body, conducting in vitro gas exchange in a lung sac cavity consisting of a lung sac cavity, an oxygen intake sac cavity, a diaphragm and capillary bundles, generating arterial blood with supersaturated oxygen content, and transfusing the arterial blood back into the veins for participating in metabolic cycles of the human body. Compared with a physiological gas exchange process of the human body, the artificial lung uses a unidirectional segmented continuous mode to replace a gas exchange mode adopting exhaling and inhaling reciprocating bidirectionally in the same breathing pipeline in an intermittent alternating way, so that the efficiency is higher and the exchange is more thorough. Compared with allopathy in medical care in the prior art which improves the supplied gas quality and increases the amount, the artificial lung changes the inherent defects of body hypoxia situations, is independent and unique, does not rely on a physiological lung to complete gas exchange, and has replacement and compensation functions for treating pulmonary function defects and insufficiencies.

Description

[0001] 1. Technical field: [0002] The invention belongs to an artificial organ for human medicine, in particular to an artificial lung for extracorporeal circulation. [0003] 2. Background technology: [0004] Respiratory movement and function are the most important and primary manifest signs of the existence of human life. The core body of the respiratory system is the lung, and the lung is a treatment method with high technical content and difficult operation in the organ that can be transplanted and replaced in modern medicine, and the effect is not ideal. Therefore, the hope of survival of patients who are life-threatening due to lung diseases and injuries is even more remote and indifferent. The existing technology deals with patients with hypoxia and dyspnea, mainly from the aspects of breathing power and gas supply quality and quantity, but it has little effect on patients with gas exchange disorders caused by the structure and function of the lungs. [0005] 3. Con...
