Abstract
The utility model belongs to a medical appliance which is an extracorporeal circulation apparatus which combines the temperature exchanging and oxygenating of blood together and which is provided with a diaphragm type oxygenator on the upper part and a temperature exchanger on the lower part, both of which are integrally assembled via connection fittings. The center of the diaphragm type oxygenator is provided with an occupation core, while an oxygenating film which is net-structured by interweave-arranged hollow cored fibers is arranged between the occupation core and the housing. An oxygen inlet pipe and a blood outlet pipe are arranged on the upper part of the diaphragm type oxygenator, and the temperature exchanger is arranged in the concave-convex shaped temperature exchanging pipe with water. The blood inlet pipe is arranged on the lower side of the temperature exchanger, and the blood passes through the recess outside the temperature exchanging pipe. The diaphragm type oxygenator which is capable of throwing away wholly has scientific and compact structure, small priming volume of blood and high efficiency on oxygenating and temperature exchanging. The utility model is disposable, and avoids cross infection.
Description
This utility model relates to the medical apparatus and instruments that a kind of intra-operative is used, and referring in particular to a kind of alternating temperature and oxygenate that collects blood is holistic extracorporeal circulation apparatus.
In known prior art, the extracorporeal circulation apparatus that clinical operation is used, be commonly called as artificial lung, bubble oxygenator and membrane oxygenator are arranged,, therefore use membrane oxygenator to replace bubble oxygenator owing to use bubble oxygenator to cause certain damage to blood component, the membrane oxygenator that development in recent years is got up structurally also exists certain shortcoming, also do not see a kind of compact conformation, the hemoperfusion amount is little, and collection oxygenate and alternating temperature are the membrane oxygenator of a single unit system.
The purpose of this utility model is to overcome the shortcoming that existing oxygenator exists, and a kind of compact conformation is provided, and the hemoperfusion amount is little, is fit to disposablely can abandon membrane oxygenator entirely.
Embodiment of the present utility model is that membrane oxygenator is assemblied in top, thermode is assemblied in the bottom, be assembled into an integral body with oxygenator connection fittings and thermode connection fittings between them, space occupying core is installed at the center of membrane oxygenator, between space occupying core and the oxygenator housing oxygenation membrane is installed, oxygenation membrane is a layout conclusion of the business knitmesh shape structure of hollow fiber, the blood shunt device is installed in the lower end of space occupying core, between blood shunt device and the oxygenator connection fittings sealing ring is installed, the oxygenator loam cake is installed on oxygenator housing top, the oxygen inlet pipe is installed on the oxygenator and covers, the blood outlet is installed in the upside of oxygenator housing, the oxygenator connection fittings are installed in the lower end of oxygenator housing, and air vent is housed thereon, in the thermode housing concave convex shape changing temperature pipe is installed, the two ends of thermode housing are installed thermode installation cover and manhole cover respectively, water inlet pipe and outlet pipe are installed on the thermode installation cover, have the discharge orifice on their tube wall, the thermode connection fittings are installed in the upside of thermode housing, and the blood inlet pipe is installed in the downside of thermode housing.
The current that venous blood is entered in the groove in the concave convex shape changing temperature pipe outside of flowing through in the thermode housing by the blood inlet pipe and concave-convex temperature is managed in the inboard tongue during use carry out heat exchange, the venous blood of the temperature that improves enters membrane oxygenator by the thermode connection fittings and flows in oxygenation membrane through the blood shunt device, absorption becomes arterial blood from the oxygen that top oxygen inlet pipe comes, flow out from the blood outlet of membrane oxygenator upside, remaining oxygen goes out from the exhaust cycle bank of tubes of membrane oxygenator upside.Carbon dioxide is discharged by the air vent of membrane oxygenator lower end.
The utility model has the advantages that blood and oxygen carry out oxygenate by oxygenation membrane and do not have direct blood gas interface, significantly reduce damage to shaped components in blood, because oxygenation membrane layout conclusion of the business knitmesh shape causes the blood eddy current, improved oxygenate efficient greatly, because oxygenator and thermode are combined into an integral body compactly, it is little that thermode adopts concave convex shape changing temperature pipe, heat exchange efficiency height, the blood of whole device to give charge.This can abandon membrane oxygenator entirely, is convenient to promote disposable use, has avoided the cross infection between the patient, and is safe and reliable.
Accompanying drawing is this utility model example structure view, the drawing explanation:
1-oxygenator loam cake, 2-oxygen inlet pipe, 3-exhaust cycle pipe, 4-oxygenator housing,
The 5-space occupying core, the 6-oxygenation membrane, 7-blood shunt device, the 8-sealing ring, 9-oxygenator connection fittings,
