Abstract
The utility model relates to a medical appliance of cardiac operations under extracorporeal circulation. The utility model comprises an oxygenation chamber, a heat exchanger, and a blood storage box having a defoaming layer and a filtering layer. The oxygenation chamber uses a central blood entering sleeve type structure. The oxygenation chamber is composed of a central post, an inner cylinder, an outer cylinder, and an overflow cylinder. The heat exchanger is arranged in an oxygenation path formed between the inner and the outer cylinders of the oxygenation chamber. The heat exchanger has the functions of oxygenation and variable temperature. The utility model has the advantages of compact structure, reasonable structure, small size, stable and thorough oxygenation property, high oxygenation effect rate, favorable effects of the variable temperature, easy use, and safety. The length of the oxygenation path can be added.
Description
This utility model relates to the disposable medical instrument that carries out the used temporary transient alternative artificial lungs function of cardiac operation under a kind of extracorporeal circulation.
The present bubble oxygenator that generally uses clinically, form by oxygenation chamber, heat-exchanging chamber and storage blood Tong with froth breaking layer and filter course, its oxygenation chamber and heat-exchanging chamber generally all are to adopt outer top or the bottom that the formula structure is connected storage blood Tong one side that connect, this version is relatively disperseed, volume is big, often brings inconvenience in transportation with in using.
The purpose of this utility model be for overcome above-mentioned deficiency provide a kind of compact conformation, rationally, volume is little, the oxygenate alternating temperature is integrated, increases the oxygenate path, and oxygenation property is stable, oxygenate efficient height, alternating temperature is effective, a kind of bubble oxygenator easy to use.
This utility model is realized by following measure:
A kind of bubble oxygenator, comprise oxygenation chamber, heat-exchanging chamber and storage blood Tong with froth breaking layer and filter course, the oxygenation chamber bottom disposes the venous blood inlet and the oxygen inlet that can be connected with duct of Arantius, blood cover Tong formula structure is advanced at oxygenation chamber employing center, be made up of newel, interior Tong, outer Tong and overflow Tong, heat exchanger is arranged in the oxygenate path that forms between the interior Tong of oxygenation chamber and the outer Tong, and there is a transparent windows upper end of oxygenation chamber in the storage blood Tong.Heat exchanger is the toroidal helical corrugated tube, and adopts stainless steel material.The froth breaking layer is made up of the sponge in two-layer different apertures.
Accompanying drawing is the structural representation of this utility model embodiment;
Among the figure: (1) oxygen intake (2) intake-outlet (3) venous blood inlet (4) liquid injection port
(5) transparent windows (6) heat exchanger (7) storage blood Tong (8) air vent
(9) the interior Tong of oxygenation chamber (10) foaming plate (11) newel (12)
(13) outer Tong (14) overflow Tong (15) froth breaking layer (16) filter course
(17) bracing frame (18) tremulous pulse outlet
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment of the present utility model comprises oxygenation chamber (9), heat exchanger (6) and has the storage blood Tong (7) of froth breaking layer and filter course as shown in drawings.The centre position of storage blood Tong is provided with a center to be advanced oxygenation chamber (9), the oxygenation chamber of blood cover Tong formula structure and is made up of newel (11), interior Tong (12), outer Tong (13) and overflow Tong (14), forms the continuous oxygenate path that makes a circulation.The outermost discharge tube of oxygenation chamber is fixedly connected on storage blood Tong bottom, and be connected to an integral body with interior Tong, the upper end of storage blood Tong is provided with a transparent windows (5), be convenient to observe blood circumstance, the upper end of the outer Tong of oxygenation chamber and transparent windows are pegged graft fixing, and the intermediary newel of oxygenation chamber (11) is connected with the transparent windows build-in.The interior Tong of oxygenation chamber and outside the heat exchanger (6) of the toroidal helical corrugated tube that adopts stainless steel material is set between the Tong.The oxygenation chamber bottom disposes venous blood inlet (3), oxygen intake (1) and the intake-outlet (2) that can be connected with duct of Arantius, and oxygen intake is located at the bottom of foaming plate (10).By bracing frame (17) fixedly froth breaking layer (15) and filter course (16), the froth breaking layer is that the sponge by two-layer different apertures constitutes in the storage blood Tong.Be provided with tremulous pulse outlet (11) outside the filter course of storage blood Tong lower end, storage blood tube top is provided with air vent (8) and liquid injection port (4).
This utility model in use, patient's vein blood connects the venous blood inlet by conduit and enters oxygenation chamber, carries out oxygenate through foaming, because the oxygenation chamber of blood cover Tong formula structure is advanced at the employing center, blood flow has increased the length in oxygenate path through circuitous continuously oxygenate path, has improved the oxygenate effect.Because heat exchanger of the present utility model is arranged in the oxygenate path that forms between the interior Tong of oxygenation chamber and the outer Tong, blood flow is under the effect of toroidal helical heterotherm tube, by shunting, converge constantly alternative flowing, produce blood film change effect, improved the oxygenate effect.The heat exchanger of the toroidal helical corrugated tube not only contact area with blood is big, and depressor area is just being put in the alternating temperature district.Blood flow rate is low, has improved the alternating temperature effect of blood flow greatly.Oxygenated blood among the storage blood Tong fully guarantees defoaming effect through the spongy layer froth breaking in the different apertures of bilayer, passes through to enter storage blood Tong (7) behind the filtering layer (16) and derived by tremulous pulse outlet (18) again.
The utility model has the advantage of: compact conformation, rationally, volume is little, and oxygenate, alternating temperature is integrated, increase The length in oxygenate path, oxygenation property is stable, fully, oxygenation efficiency height, effective, easy to use, the peace of alternating temperature Complete reliable.
