Abstract
The utility model discloses a disposable bubbling oxygenator (manual lung), comprising an oxygenation room which is communicated with the vein tube, the oxygenation room is horizontally provided with an oxygen dispersion machine, one end of the oxygenation tube vertically goes through the oxygen dispersion machine and is communicated with the oxygenation room. A heat exchange wave tube is arranged on the oxygenation tube, a secondary counterflow heat exchanger is formed by the combination of the oxygenation tube, the heat exchange wave tube and the oxygenator casing, the blood exit end of the heat exchanger is communicated with a disposable bubbling net, a filtering net and an artery blood bank. The utility model has the characteristics of small oxygen/blood proportion, stable oxygenation, large oxygenation amount, low price, and is suitable for the need of various patients.
Description
This utility model is a kind of oxygenator (artificial lung), particularly a kind of all disposable bubble oxygenators (artificial lung) of can abandoning entirely.
People such as nineteen fifty-three Gibbon successfully are applied to spiral cast bubble oxygenator (artificial lung) clinical experiment, (document 1: " cardiovascular surgery ", Lan Xichun etc., P233,1985, People's Health Publisher).But, the oxygen of this bubble oxygenator/blood ratio big (3～5:1), blood is destroyed big, can not adapt to the clinical operation requirement.Along with the raising of science and technology development and industrial level, the seventies foreign scholar again research and development novel bubble oxygenator---pocket type and hard-shell type can be abandoned bubble oxygenator (document 2:Michele F.Roesler, etal entirely.Clinical use of the Shiley oxygenating system。Marian I。Ionescu，MD，FACS Techniquesin extracorporeal Circulation。Butterworth 8 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, avoided the cross infection between the patient, but the oxygen/blood ratio of this oxygenator is still bigger than normal, can not adapt to longer 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.
To be that design is a kind of all disposablely can abandon bubble oxygenator to the purpose of this utility model entirely, has that oxygen/the blood ratio is little, oxygenate stable, the oxygenate amount is big, is suitable for the characteristics of various needs of patients.
This utility model comprises a rotary blood flow oxygenation chamber that can communicate with duct of Arantius, horizontal arrangement monoxide disperser in the oxygenation chamber, one end of one oxygenate pipe vertically pass the oxygen disperser and and oxygenation chamber communicate, cover is furnished with heat-exchange corrugated pipe on the oxygenate pipe, oxygenate pipe, heat-exchange corrugated pipe and oxygenator shell thereof are combined into a second adverse current formula heat exchanger, the blood port of export of heat exchanger is communicated by the filter chamber that goes to indulge in serfing the Net, drainage screen surrounds with one, and the filter chamber is configured in the tremulous pulse blood bank.
The oxygen disperser can be 45 * 10 by the aperture
-6Rice is to 55 * 10
-6Many micropore titanium plates between the rice are made; Whole oxygenator can be by injection molded, and is bonding in aggregates.
After venous blood enters rotary blood oxygenation chamber, the effect that is rotated in the oxygen disperser along the bottom and the tangential direction of oxygenation chamber forms size to fit down and after the oxygen mix, many and bleeding blister foam uniformly, form the foamy blood of blood because its light specific gravity, buoyancy is big, centrifugal force is little, just enter in the oxygenate pipe of central part, behind the heat-exchange corrugated pipe countercurrent flow first time, flow out the oxygenate pipe and after the countercurrent flow second time is carried out in the outside of heat-exchange corrugated pipe, flow into the filter chamber, through the outer wall of filter chamber---go to indulge in serfing the Net and go to steep with drainage screen, enter the arterial blood storehouse after the filtration.
This shows that oxygen disperser air penetrability of the present utility model is big, resistance is little, thereby oxygen mixes the bleeding blister size to fit that the back forms with venous blood, many and evenly.In addition, owing to oxygenate circuit of the present utility model is second adverse current and wherein disposes heat-exchange corrugated pipe, thereby not only increased the oxygenate path, and made bleeding blister fully roll, thereby increased the oxygenate effect.
Accompanying drawing is a structure principle chart of the present utility model.
Among the figure, (1) be vein blood inlet, (2) be oxygenation chamber, (3) be oxygen disperser, (4) be oxygenate pipe, (5) be heat-exchange corrugated pipe, (6) be indulge in serfing the Net, (7) be that drainage screen, (8) they are that tremulous pulse blood bank, (9) they are that arterial blood outlet, (10) they are heat exchangers, heat exchanger (10) is made up of oxygenate pipe (4), heat-exchange corrugated pipe (5) and oxygenator shell thereof, and (11) are the filter chambers.
According to Xijing-87 type oxygenator of principle design of the present utility model, its oxygen/blood ratio is 0.4～0.7:1, and the oxygen/blood ratio of external like product is 2～3:1; And this utility model is when oxygen/blood constant rate, and blood flow is big more, and oxygenate is good more, in certain oxygen/blood proportion, along with the increase of oxygen/blood ratio, the oxygenate effect obviously increases, under other parameter the same terms, heat exchange coefficient improves more than 8%, and price reduces greatly.
Claims (2)
1, can abandon bubble oxygenator entirely, comprise an oxygenation chamber that can communicate with duct of Arantius, heat exchanger, what communicate with the blood port of export of heat exchanger indulges in serfing the Net by going, the tremulous pulse blood bank of filter chamber that drainage screen surrounds and outside, filter chamber, feature of the present utility model is, said oxygenation chamber is a rotary blood oxygenation chamber, in it end of a horizontal arrangement monoxide disperser and an oxygenate pipe vertically pass the oxygen disperser and and oxygenation chamber communicate, cover is furnished with heat-exchange corrugated pipe, oxygenate pipe on the said oxygenate pipe, heat-exchange corrugated pipe and oxygenator shell thereof are combined into a second adverse current formula heat exchanger.
2, according to claim 1ly can abandon bubble oxygenator entirely, it is characterized in that said oxygen disperser can be 45 * 10 by the aperture
-6Rice is to 55 * 10
-6Many micropore titanium plates between the rice are made.
