Abstract
The utility model relates to a bubble type oxygenator which can utilize residual blood, which comprises an oxygenation chamber and a heat exchanging chamber arranged on the upper part or the lower part of the oxygenation chamber. The oxygenation chamber is provided with a vein blood inlet which can be communicated with a vein pipe and an oxygen inlet which is communicated with outside oxygen; a blood outlet on the upper part of the heat exchanging chamber is communicated with an artery blood bank, the artery blood bank is communicated with the openings on the lowest positions of the oxygenation chamber and the heat exchanging chamber by pipelines, when cardiopulmonary bypass are ended, residual blood in the heat exchanging chamber can be infused into human bodies through the blood bank. The utility model has the advantages of simple structure and high utilization rate of blood.
Description
This utility model relates to a kind of oxygenator (artificial lung), particularly a kind of disposable bubble oxygenator (artificial lung).
People such as nineteen fifty-three Gibbon successfully are applied to spiral cast bubble oxygenator (artificial lung) clinical) [document 1: " cardiovascular surgery ", Lan Xichun etc., P233,1985, People's Health Publisher].But the oxygen of this bubble oxygenator/blood ratio is big by (3～5: 1), blood is destroyed greatly, can not adapt to the clinical operation requirement.Raising along with science and technology development and industrial level, the seventies foreign scholar again research and development novel bubble oxygenator---pocket type and duricrust can be abandoned bubble oxygenator [document 2:Michele F.Roesleretal entirely, Clinical use of the Shiley oxygenating system.Marian I.Ionescu, MD, FACS Techniquesin extracorporealcirculation, Butterworth﹠amp; Co (Publication) Ltd 1981.In England, ], although the gas exchange of this oxygenator can satisfy the clinical operation requirement substantially, oxygen in the cardiopulmonary bypass process/blood ratio descends to some extent, and disposable use, has avoided the cross infection between the patient, but the oxygen of this oxygenator/blood ratio is still bigger than normal, can not adapt to long period patient with operation needs, and oxygenate is stable inadequately and the oxygenate amount is big inadequately, the normal heavy patient's oxygenate bad phenomenon substantially that occurs.Number of patent application CN88213357.8 discloses a kind of bubble oxygenator of abandoning, the oxygenate foaming chamber improved and the oxygenate path of lengthening have been adopted, make the oxygen/blood ratio little (0.6: 1) of oxygenator, oxygenate is stable, the oxygenate amount is bigger, but, after this kind oxygenator uses and finishes, residual in its heat-exchanging chamber have a large amount of blood (100～300ml), these blood are thrown away together because of reclaiming with oxygenator, and when operation, in order to satisfy patient blood circulation needs, having to has again not only increased operating difficulty to additionally giving hyperemia in the artificial heart-lung, and the blood waste is serious, causes blood source anxiety and has increased patient's financial burden.
The purpose of this utility model is to propose a kind of bubble oxygenator that improves structure, can guarantee in cardiopulmonary bypass finishes the back heat-exchanging chamber left blood by oxygenator blood bank input human body, have simple in structure, the characteristics that the blood utilization rate is high.
Essence of the present utility model is to open a through hole at the minimum position of oxygenate one heat-exchanging chamber of bubble oxygenator, communicates with tremulous pulse blood bank by pipeline.This pipeline intermediate configurations one control blood valve 16 and one " Y " type joint 15 is so that extract the arterial blood specimen.
Use of the present utility model can realize its purpose by the method method:
Configuration one valve on the pipeline is closed through hole and filter chamber's passage when operation; After operation, open the passage of through hole and filter chamber, residue blood flows into the filter chamber by through hole under action of gravity, through going to enter the arterial blood storehouse after bubble and the filtration, import human body at last, thereby make the left blood in the heat-exchanging chamber obtain effective utilization.
This shows, the utlity model has following characteristics:
1, reduced the waste of blood, patient's autoblood is fully utilized, and avoided bringing, easily caused drawbacks such as cross infection to the defeated storehouse of patient blood.
2, simple in structure, be particularly suitable for having now the transformation of oxygenator.
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is an embodiment of the present utility model.
Fig. 3 is another embodiment of the present utility model.
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are done detailed explanation.
With reference to Fig. 1, this utility model comprises an oxygenation chamber 2, is configured in the heat-exchanging chamber 10 of oxygenation chamber 2 bottoms, the blood bank 8 that is connected with the blood outlet on heat-exchanging chamber 10 tops.Dispose vein blood inlet 1 that can communicate and the oxygen inlet 13 that communicates with extraneous oxygen on the oxygenation chamber 2 with duct of Arantius, horizontal arrangement monoxide disperser 3 in the oxygenation chamber 2, one end of one oxygenate pipe 4 vertically pass the oxygen disperser and and oxygenation chamber 2 communicate, cover is furnished with heat-exchange corrugated pipe 5 on oxygenate pipe 4 other ends, heat-exchange corrugated pipe 5 is configured in the heat-exchanging chamber 10, the blood outlet on heat-exchanging chamber 10 tops and one is by going to indulge in serfing the Net 6, the filter chamber 11 that drainage screen 7 surrounds communicates, filter chamber 11 is configured in the tremulous pulse blood bank 8, have a through hole 17 in the tremulous pulse blood bank 8, through hole 17 is connected by the perforate 14 of pipeline 20 with oxygenate one heat-exchanging chamber 10 lowest orders.Configurable valve 16 and " Y " type joint 15 on the pipeline 20 is so that control blood is mobile.After the operation, open valve 16, residue blood is promptly flowed in the tremulous pulse blood bank 8 through pipeline 20, through hole 17 by perforate 14, again by in the blood outlet 9 input patient bodies.
In addition, among the figure, the 12nd, mouth, the 18th, the water inlet of heat-exchange corrugated pipe 5, the 19th, outlet are regulated in aerofluxus.
With reference to Fig. 2, among this embodiment, oxygenation chamber 2 and bottom interior, that oxygen disperser 3, oxygen inlet 13, vein blood inlet 1 configuration on it are configured in heat-exchanging chamber 10 thereof, blood carries out heat exchange from the bottom to top.The heat-exchange corrugated pipe 5 of this embodiment is enclosed within on the hollow stay pipe 24.In order to strengthen the oxygenate effect, 11 tops, filter chamber dispose a diversion column 21.Pipeline 20 can be connected with perforate 14 or be connected with vein blood inlet 1 after operation finishes, and specific embodiments is: block perforate 14, configuration one threeway check valve between vein blood inlet 1, vein blood vessel and pipeline 20.After operation finishes, start the threeway check valve, cut off the passage between vein blood inlet 1 and the vein blood vessel, the passage of opening between vein blood inlet 1 and the pipeline 20 gets final product.
With reference to Fig. 3, the oxygen disperser 3 of this embodiment, oxygen inlet 13, vein blood inlet 1 are configured in the bottom of heat-exchanging chamber 10.Oxygenate pipe 4 is configured among the filter chamber 11, and the baffle 22 of its upper end configuration one gradual shrinkage is beneficial to blood flow and oxygenate; Configuration one " U " jacket 23 in the filter chamber 11 of its lower end, being beneficial to dirty blood flow can upwards reflux around oxygenate pipe 4, forms and rolls, and has further improved the oxygenate effect.Pipeline 20 can communicate with perforate 14 or be connected with venous blood mouth 1 after operation finishes.
