Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of extracorporeal circulation apparatus that can temporarily substitute the gas exchange function of lung.
Background technology
In clinical medicine, because the strike of operation and extracorporeal circulation, obstinate severe hypoxia mass formed by blood stasis can appear in postoperative patient.Promptly use respirator treatment all invalid, cause MOFE such as heart failure, renal failure, blood system at last, critically ill.In addition, cause patient's acute respiratory failure also comparatively common by a variety of causes.This situation is similar to a people and can not breathes: though blood is still flowing, do not have enough oxygen to utilize for tissue in the blood, the activity of whole body organ all will stop thereupon.Therefore, in order to save people's life, artificial lung arises at the historic moment." artificial lung " medically is called external membrane lung, is by a drainage tube venous blood to be drained into to carry out oxygenate in the external membrane lung, and another root drainage tube of reuse will be full of the blood pump ex vivo angular vein of new fresh oxygen or the technology of tremulous pulse.It can temporarily substitute the gas exchange function of lung and the pumping function of heart, improves circumfusion, prolongs patient's life, for the patient who suffers from the severe cardiac pulmonary insufficiency provides the therapy apparatus meeting, for the recovery of cardio-pulmonary function is raced against time.Because artificial lung is the non-physiological state extracorporeal circulation supporting technology of a long period, the application requirements in clinical is very high.
The artificial lung machine is made up of oxygenator and blood pump and auxiliary facilities, can carry out the machinery of extracorporeal circulation. and the artificial lung machine is used for the extracorporeal circulation of operation on heart, the assisted respiartion of lung transplantation, the auxiliary treatment of acute respiratory failure etc.
Artificial lung machine basic functional principle
The venous blood of superior and inferior vena cava or right atrium is drawn by pipeline, flow into oxygenator (being artificial lung) and carry out oxygenate, pass through blood pump (the artificial heart) again, to keep the physiological function of body when circulation is blocked the input of the blood behind oxygenate Arterial system.
So blood is called cardiopulmonary bypass without the process of carrying out oxygenate and perfused tissue from the cardiopulmonary of body, also is called extracorporeal circulation.
Artificial lung has two types substantially at present: membrane type (contactless artificial lung), bubble type (contact artificial lung).Bubble type artificial lung is that oxygen bubbles directly contacts with blood and carries out gas exchange, though gas exchange rate is big, and dissolved oxygen skewness in the blood, and the serum albumin degeneration, be easy to generate haemolysis, produce thrombosis and aeroembolism, lack usefulness safely inadequately, just eliminated gradually.And contactless artificial lung is owing to separate with the good polymeric membrane of breathability between blood and the oxygen, oxygen can directly see through film and blood oxygenation, thereby be called membrane artificial lungs, membrane artificial lungs is made up of tens thousand of doughnut boundlings, be covered with micropore on the every doughnut surface, these holes are minimum, blood is oozed do not go out, but can discharge carbon dioxide, take in oxygen, carry out gas exchange.Therefore changed the mode that oxygen bubbles and blood in the past directly contact exchange, by the gas exchange between microporous membrane realization oxygen, carbon dioxide and the blood, it is little to have haemolysis, the characteristics that the serum albumin degeneration is little, be widely used in the extracorporeal circulation of cardiovascular and cerebrovascular vessel operation, America and Europe almost 100% application model artificial lung carries out extracorporeal circulation.But the carbon dioxide of discharging can not in time be rejected to outside the device, occupy certain space, make gas exchange rate not reach the oxygenate speed of bubble type for a short time, the treatment of cardiac operation does not reach effect preferably, but also the long various cardiopulmonary operative treatments of incompatibility operating time.Present artificial lung of while also exists bulky, carries inconvenience, has limited the wounded or individual's use.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of gas exchange rate big, and volume is little, the extracorporeal circulation apparatus of the gas exchange function that can temporarily substitute lung easy to carry and the pump of heart.
In order to solve the problems of the technologies described above, the invention provides a kind of artificial lung, comprising:
A kind of artificial lung comprises housing, blood pump, advances blood vessel and blood back pipe, and the inwall of described housing is fixed with Na
2O
2Plate, the import of blood pump is connected with netted scavenge trunk, and outlet is connected with the blood back pipe; The front end of scavenge trunk with advance blood vessel and link to each other; The front end that advances blood vessel is connected with blood taking needle; The end of blood back pipe is connected with the blood back pin.Netted scavenge trunk is made up of tens thousand of doughnut boundlings, has been covered with micropore on the every doughnut surface, and this hollow-fibre membrane that is used for artificial lung roughly is divided into two types, homogeneous membrane and perforated membrane.Homogeneous membrane makes infiltration gas keep motion by the mode that allows gas molecule dissolving and diffuse in the film, for example the film made of silicone rubber.The pore of perforated membrane is compared much bigger with gas molecule, flow in a large number so perforated membrane can allow infiltration gas pass pore, for example the perforated membrane of capillary polypropylene.Doughnut of the present utility model includes but not limited to above-mentioned two types film.

Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, in the drawings: the 1-blood taking needle, 2-advances blood vessel, 3-Na
2O
2Plate, 4-scavenge trunk, 5-housing, 6-blood pump, 7-blood back pipe, 8-blood back pin.
The specific embodiment
Describe the present invention below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.
The design is the device of a kind of anthropomorphic dummy's lung functions.Be illustrated as this device overall schematic.
In this device, housing 5 can be done shapes such as circular, and its inwall is fixed with Na
2O
2Plate 3 and within it portion blood pump 6 is housed; The import of blood pump 6 is connected with netted scavenge trunk 4, and the outlet of blood pump 6 is connected with blood back pipe 7; The front end of scavenge trunk 4 with advance blood vessel 2 and link to each other; The front end that advances blood vessel 2 is connected with blood taking needle 1; The end of blood back pipe 7 then is connected with blood back pin 8.
The vein blood vessel that blood taking needle 1 is penetrated human body is taken a blood sample, under the effect of blood pump 6, to the device blood supply, former blood enters into netted scavenge trunk 4 through advancing blood vessel 2, after oxygen enters the endoporus of doughnut, oxygen just the micropore from the doughnut to external diffusion, thereby with venous blood generation Oxygenation, simultaneously, the higher carbon dioxide of dividing potential drop is just discharged to the doughnut internal diffusion by doughnut on the netted scavenge trunk from blood in the venous blood, becomes approximate arterial blood thereby make venous blood absorb oxygen and discharge carbon dioxide.The carbon dioxide of discharging through with inner walls on Na
2O
2The plate acquisition oxygen that works, the oxygen of acquisition since dividing potential drop low enter the doughnut of netted scavenge trunk once more and from micropore to external diffusion, send out Oxygenation with venous blood, form approximate arterial blood, and release CO
2, carbon dioxide again with Na
2O
2Plate works, and circulation makes gas exchange rate big so repeatedly, has reached the oxygenate speed of bubble type artificial lung, reaches better medical effect.Approximate arterial blood flow to blood back pin 8 via blood back pipe 7, injects other end vein blood vessel by blood back pin 8 again.So far finish this cycle of operation.
