The device is composed of a transforming interface, a roller pump, a blood purifier, an external membrane oxygenator and an open type oxygen interface, wherein, the components are connected into a blood flow loop through aseptic polyethylene pipelines. The correlated arrangement for the blood flow volume of the whole blood loop and for blood purification can be controlled through a blood-purifying machine. The utility model has the advantages of simple, scientific and reasonable structure, low cost, good safety, good practicability and good serviceability. The utility model can be used for treating severe acute respiratory distress syndromes.
Description
Technical field
This utility model belongs to medical instruments field, relates to blood purification and extracorporeal membrane oxygenation integrated apparatus, relates to the integration technology when using blood purification and extracorporeal membrane oxygenation simultaneously.
Background technology
The poverty-stricken syndrome of severe acute respiratory (ARDS) is more common critical illness (the SARS underlying cause of death also is ARDS), mortality rate is very high, main treatment at present is a mechanical ventilation, sometimes can't reach therapeutic goal but rely on mechanical ventilation merely, therefore be necessary very much to use new device and technology to improve this situation for some patients with severe symptoms.Blood purification and extracorporeal membrane oxygenation are the technology of having used clinically, blood purification have been applied to rescue serious symptom ARDS, and extracorporeal membrane oxygenation then is applied in the extracorporeal circulation when cardiac surgery operation, and it is unusual effectively to improve vim and vigour ARDS patient.Think that at present inflammatory mediators such as cytokine play an important role in the pathogenic process of ARDS, and blood purification can be treated the mechanism of ARDS and just is that it can remove in the blood circulation the unusual inflammatory factor that raises, but the intractable hypoxemia that causes for ARDS does not then have obvious mitigation in a short time; Although extracorporeal membrane oxygenation can effectively improve body hypoxemia and hypercapnia, can cause the rising of part inflammatory mediator level in the blood, this also is the reason that extracorporeal membrane oxygenation can not improve ARDS patient's prognosis.If but with blood purification and extracorporeal membrane oxygenation use in conjunction, then can overcome shortcoming separately, thereby better performance therapeutical effect separately: the effect that blood purification improves hypoxemia and hypercapnia can be remedied by extracorporeal membrane oxygenation, and the inflammatory mediator in the blood that extracorporeal membrane oxygenation produces can be removed by blood purification, final rising learnt from other's strong points to offset one's weaknesses the effect of mutual supplement with each other's advantages.Have not yet to see device and technology report that The combined is used.
Summary of the invention
The purpose of this utility model provides a kind of blood purification and extracorporeal membrane oxygenation integrated apparatus, and it can be used with respirator and rescue the poverty-stricken syndrome of severe acute respiratory (ARDS).
This utility model integrated apparatus is simple and reasonable, with blood purification and extracorporeal membrane oxygenation organic combination.
Of the present utility model being constructed as follows: it is mainly by translation interface, hsempdiakysing systems, and the extracorporeal membrane oxygenation device, the oxygen interface, blood purifications etc. are formed by connecting by the aseptic polyethylene pipeline.Wherein the power drive blood that provides of the roller pump of hsempdiakysing systems flows in extracorporeal membrane oxygenation device and blood purification, mobile direction is for being introduced into blood purification, enter extracorporeal membrane oxygenation subsequently, be polyphone between the two, and the extracorporeal membrane oxygenation device is by being connected oxygen supply with the oxygen interface.Control and regulate the flow of blood in the whole circulation and other parameter of blood purification by hsempdiakysing systems; Carry out aerofluxus by the exhaust apparatus in the polyethylene pipe, to prevent air embolism.Realize the connection of whole blood circuit by translation interface.
The advantage of this utility model device is: realized the integrated of blood purification and extracorporeal membrane oxygenation by translation interface, hsempdiakysing systems, extracorporeal membrane oxygenation device, blood purification and aseptic polyethylene pipeline, made blood just can finish the treatment of blood purification and extracorporeal membrane oxygenation by a loop; Oxygen interface of the present utility model can be open, the safe oxygen supply in the time of being implemented in low-down blood flow, because the pressure of oxygen should be less than the pressure in the blood circuit during extracorporeal membrane oxygenation, otherwise the hollow-fibre membrane of membrane oxygenator will break; Translation interface makes between the interface of different size bore on extracorporeal membrane oxygenation device and the blood purification and realizes being connected smoothly, to guarantee the complete of loop.This utility model is simple in structure, scientific and reasonable, and is safe and convenient to use, cheap.Final therapeutic effect can be realized learning from other's strong points to offset one's weaknesses, and has complementary advantages, and the practicality and the suitability are all good.
Description of drawings
Fig. 1. be this utility model apparatus structure sketch map.
Wherein, the 1st, translation interface, the 2nd, roller pump, the 3rd, blood purification, the 4th, the extracorporeal membrane oxygenation device, the 5th, open oxygen interface, the 6th, by polyethylene pipe, the 7th, the patient.
Accompanying drawing is this utility model embodiment accompanying drawing.
Be further described this use is novel according to above-mentioned accompanying drawing.This utility model is by translation interface 1, roller pump 2, and blood purification 3, extracorporeal membrane oxygenation device 4, open oxygen interface 5 is formed by connecting by polyethylene pipe 6, constitutes the blood flow loop.Wherein patient 7 blood draw the back by polyethylene pipe 6 and conversion connect 1 mouthful roller pump 2 driving under enter blood purification 3, after carrying out blood purification, enter (oxygen supply is by open oxygen interface 5) in the extracorporeal membrane oxygenation device 4 by pipeline and translation interface, after gas exchange carries out, drive through roller pump again and fail back in patient's body, the blood flow of whole blood circuit is controlled and is regulated by roller pump 2, and the parameter of blood purification is provided with and adjusts by hsempdiakysing systems.
This utility model is simple in structure, scientific and reasonable, and cost is low, can be used for the treatment of the poverty-stricken syndrome of severe acute respiratory.Through clinic trial, show that this blood purification and extracorporeal membrane oxygenation integrated apparatus can treat the patient under the state of safety, its safety, practicality, the suitability are good.
