Abstract
The utility model relates to a mini-membrane type blood oxygenator for multi-blood stream, which belongs to the technical field of medical apparatus and comprises a heat exchanger, a gas exchanger and an arterial micro embolism filter, wherein the heat exchanger and the gas exchanger form a cuboid shape and are orderly and in series connected into an integrative body; inner cavities of the heat exchanger and the gas exchanger are respectively divided into two chambers through partition plates along the one third position of the length direction of the inner cavities; the arterial micro embolism filter forms an elliptical shape. The utility model can be changed into three types of blood flowing quantity and has the advantages of simple production, flexibility and convenience and is suitable for extracorporeal circulation and perfusion for baby's different bodies and for long-term supporting cardiorespiratory functions for patients with cardiopulmonary insufficiency.
Description
This utility model belongs to technical field of medical instruments, further belongs to replace people's lung to carry out the small-sized membrane oxygenator of multiple blood flow of gas exchange when being used for open heart operation with extracorporeal circulation.
The at present clinical bubble oxygenator that adopts, its operation principle is that oxygen is blown into venous blood, to form foam, finishes the oxygenate process more.Disclosed as Chinese utility model patent 88213357.8: " can abandon bubble oxygenator entirely ".This bubble oxygenator does not meet Human Physiology because vim and vigour directly contact.Membrane oxygenator is to make oxygen enter blood by the dispersion of one deck capillary-pipe film, carbon dioxide disperse from blood is come out, thereby finish gas exchange.As people's alveolar, blood does not directly contact with gas during oxygenate, and slight to the blood formed element damage, albuminous degeneration is light, and the danger of no gas thromboembolism is a kind of physiological oxygenator that meets.Though existing market has multiple adult type membrane oxygenator for clinical selecting for use, still do not have suitable different weight infant and be fit to the small-sized membrane oxygenator of multiple blood flow that long-term cardiopulmonary are supported.
The purpose of this utility model is, provides a kind of and is suitable for not consubstantiality infants outer filling, and the multiple blood flow membrane oxygenator of the long-term cardio-pulmonary function support of pulmonary insufficiency patient.
This utility model comprises heat exchanger, gas exchanger and tremulous pulse Micro-Bolt Filter.Heat exchanger and gas exchanger are all cuboid, and the order polyphone is one./ 3rd punishment along its length do not separate with dividing plate in the cavity of heat exchanger and gas exchanger, are divided into two Room.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Heat exchanger 1 of the present utility model and gas exchanger 2 are all cuboid, and order is connected as a single entity./ 3rd punishment along its length Yong not separate by dividing plate 7 in the cavity of heat exchanger 1 and gas exchanger 2, are divided into two Room.This utility model also can be with heat exchanger 1, and gas exchanger 2 and tremulous pulse Micro-Bolt Filter 3 order polyphones are one.
Heat exchanger 1 be with the ellipse aluminum pipe as heat-exchange tube 4, admittedly be encapsulated in a cuboid intracavity, two glue envelope 5 makes blood flow through 6 heat-exchange tube 4 outside, falls, rewarming water is mobile in heat-exchange tube 4, finishes heat exchange.Heat exchanger 1 is divided into two Room along cavity length direction 1/3rd places with dividing plate 7.Blood enters from advancing blood vessel 8, and the passage 9 from offside heat exchanger 1 and gas exchanger 2 after the heat exchange enters gas exchanger 2.
Gas exchanger 2 is the intracavity that polypropylene hollow fiber 10 (oxygenation membrane) are encapsulated in admittedly a cuboid, two glue envelope 5.As heat exchanger 1, be divided into 1/3rd and 2/3rds liang of chambers with dividing plate 7.Blood enters gas exchanger 2 from the passage 9 of heat exchanger 1 and gas exchanger 2, and the passage 11 from offside gas exchanger 2 and tremulous pulse Micro-Bolt Filter 3 behind the oxygenate enters tremulous pulse Micro-Bolt Filter 3.Oxygen flows in hollow fibre 10, and blood flows outside fiber 10, finishes gas exchange.
Tremulous pulse Micro-Bolt Filter 3 is oval working of plastics, is filled with fibrous filter layer 13 between the two-layer screen cloth 12, to filter small embolus.Blood flows out from exporting 14 then.
This utility model is the small-sized membrane oxygenator of multiple blood flow, makes simply, uses model with wide, and is flexible.
Heat-exchange tube of the present utility model is oval aluminum pipe, can reduce resistance of blood flow, improves heat exchanger effectiveness.There are three kinds of blood flows can be applicable to the extracorporeal circulation cardiopulmonary bypass and the pulmonary insufficiency patient of infant cardiac operation under direct vision for selecting for use, serious pulmonary function injury patient's long-term cardio-pulmonary function support in war wound, the wound.Need the visual oxygenate situation of the latter and patient, with its 1/3, or with its 2/3, or both merge use, change flow at any time.Can avoid changing oxygenator and hyperoxygenation or oxygenate bad phenomenon temporarily.
Claims (3)
1, the small-sized membrane oxygenator of multiple blood flow, it comprises heat exchanger, gas exchanger and tremulous pulse Micro-Bolt Filter, it is characterized in that, described heat exchanger and gas exchanger are all cuboid, and the order polyphone is one, and 1/3rd punishment along its length are not divided into two Room with dividing plate in the cavity of heat exchanger and gas exchanger.
2, the small-sized membrane oxygenator of multiple blood flow as claimed in claim 1 is characterized in that: described heat exchanger, gas exchanger and tremulous pulse Micro-Bolt Filter are contacted in proper order and are that one, tremulous pulse Micro-Bolt Filter are oval.
