Abstract
It the utility model is related to a kind of microchannel artificial bionic lung device.Exported including air inlet, blood entry port, oxygenation device, gas outlet and blood, it is characterised in that oxygenation device is made of multiple transport module longitudinal stacks, is connected between single transport module by vertical channel.Blood channel, oxygen channel and film are included in the single transport module.The film is used to isolate blood channel and oxygen channel, and gas can free in and out film.The blood channel, oxygen channel and vertical channel are process based on MEMS technology, are added surface-to-volume ratio, are effectively improved oxygen transfer coefficient.The blood channel, oxygen channel and the flowing of membrane analogy people's lung medium vessels and the physiology composition microvessel network of oxygen transmission, transition at smoother blood flow path and branch point is provided, with the thinner gas transfer membrane closer to actual alveolar film thickness, make the control of wall shear stress within physiology limitation.
Description
Technical field
A kind of bionic lung device is the utility model is related to, particularly a kind of microchannel artificial bionic lung device.
Background technology
Extracorporeal oxygenation device is the short-term Breathing Suppotion and acute in performing the operation currently used for coronary artery bypass grafting (CABG)
The rescue of Respiratory Distress Syndrome(RDS) (ARDS) patient, but extracorporeal oxygenation device can only short-period used, and required hemoperfusion
Volume is excessive, will cause serious safety problem and simultaneously to the heavy dependence of high concentration anti-coagulants in the patient for carrying out film oxygen conjunction
Send out disease high rate.
Chronic lung diseases need long-term Breathing Suppotion, and organ transplant is the effective treatment means of current chronic lung disease, but
The shortcomings that due to donor organ critical shortage and immunosuppressive therapy, is, it is necessary to develop more longlasting and potential wearable oxygen syzygy
System so that the technology can be safer and be more effectively applied to acute and chronic tuberculosis illness, and will improve and extend and is big
Measure the life of patient.
In a series of experiments chip application produced based on MEMS micro-processing technology, just positive exploration is used to support
The medical treatment device of the organs such as liver, kidney and lung.
Utility model content
The utility model is based on MEMS micro-processing technology, designs a kind of microchannel artificial bionic lung device.
The technical solution of the utility model is：
A kind of microchannel artificial bionic lung device, including air inlet, blood entry port, oxygenation device, gas outlet and blood go out
Mouthful, oxygenation device is made of multiple transport module longitudinal stacks, is connected between single transport module by vertical channel.The list
Blood channel, oxygen channel and film are included in a transport module.The film is arranged between blood channel and oxygen channel,
For isolating blood channel and oxygen channel, gas can free in and out film.
The beneficial effects of the utility model are：Blood channel, oxygen channel and vertical channel be based on MEMS technology process and
Into adding surface-to-volume ratio, effectively improve oxygen transfer coefficient.In the blood channel, oxygen channel and membrane analogy people's lung
Blood flow and the physiology of oxygen transmission composition microvessel network, there is provided the mistake at smoother blood flow path and branch point
Cross, there is the thinner gas transfer membrane closer to actual alveolar film thickness, the control of wall shear stress is limited it in physiology
It is interior.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of the utility model.
Fig. 2 is a kind of structure diagram of single transport module.
Fig. 3 is a kind of plan of single transport module.
Fig. 4 is a kind of cross-sectional view of single transport module.
Embodiment
As shown in Figure 1, blood and air flow into what is be made of multilayer transmission module 6 from blood entry port 1 and air inlet 2 respectively
Oxygenation device 3, flows out through blood outlet 4 and gas outlet 5；
From attached drawing 2,3, it is connected with each other between transport module 6 by vertical channel 7, single transport module 6 is by oxygen
Passage 8, blood channel 9 and film 10 form；Vertical channel 7, oxygen channel 8 and blood channel 9 be based on MEMS technology process and
Into.
From attached drawing 4, film 10 is arranged between blood channel 9 and oxygen channel 8, for isolating 8 He of oxygen channel
Blood channel 9, gas can free in and out film 10；People's lung medium vessels stream is simulated by oxygen channel 8, blood channel 9 and film 10
Dynamic and oxygen transmission physiology composition microvessel network, there is provided the transition at smoother blood flow path and branch point, has
Closer to the thinner gas transfer membrane of actual alveolar film thickness.
