Abstract
The utility model relates to a film type oxygenator for an animal experiment. An oxygenator in prior art is not suitable for the experiment of a small animal because of big priming volume. The film type oxygenator for an animal experiment comprises a blood heat exchanger and the oxygenator. A heat exchanger in the oxygenator is connected with the oxygenator. A blood inlet is arranged on one end of the heat exchanger, and a blood outlet is arranged on one end of the oxygenator. The water inlet and the water outlet of the heat exchanger are arranged on the same side. The gas inlet and outlet of the oxygenator are respectively arranged on both sides. The outer diameter of dynamic heating fiber is 0. 2mm-1. 2mm, and the wall thickness is 0. 02mm-0. 1mm, so the utility model is suitable for small animals. The oxygenator has the advantages of simple structure, high oxygenation efficiency, and low price; the oxygenator can satisfy the requirement of the animal experiment.
Description
Technical field
This utility model belongs to medical experiment equipment, is a kind of membrane oxygenator that is used for extracorporeal circulation experiment usefulness.
Background technology
Oxygenator claims artificial lung again, but the short time substitutes the function of lung.Be indispensable equipment in the extracorporeal circulation experiment, in the prior art,, be used for its priming volume of toy (as rat) and still seem too big, and cost an arm and a leg though the ertro corporeal membrane oxygenation device that clinical operation is used has different specifications.
Summary of the invention
The purpose of this utility model provides a kind of extracorporeal circulation state can simulate clinical operation the time, and is applicable to toy (as rat), and volume is little, and is simple in structure, the heat transfer efficiency height, and oxygenate is effective, the novel oxygenator that price is low.
Technology implementation scheme of the present utility model is that oxygenator and thermode are linked together by connection cover.Oxygenator adopts the external blood circulation streaming, and the hollow-fibre membrane of braiding is looped around the oxygenator shell of packing on the oxygenator inner core, and two ends seal with polyurethane adhesive, adopts bleed bottom mouth mode, reduces the probability of aeroembolism.Blood and the reverse flow of oxygenate gas help the discharge of oxygenate and carbon dioxide.Thermode is walked the blood flow formula in adopting, and blood is from thermode one end entrance.Thermode is made by the doughnut of high polymer, and blood flows in doughnut, and heat transfer medium flows outside doughnut, and heat transfer medium and blood reverse flow make it higher heat transfer coefficient.This utility model is suitable animal, so the long 100-150mm of oxygenator, diameter 16-22mm; The long 100-130mm of thermode, diameter 16-22mm.
The water inlet of this utility model thermode, outlet are all in the same side of thermode.
The gas access of this utility model oxygenator is in the end of oxygenator, and gas outlet is positioned at a side of oxygenator.The doughnut external diameter of thermode is 0.2-1.2mm, and wall thickness is 0.02-0.1mm, is more suitable for the use in toy.
Venous blood enters thermode from blood inlet (1) during use, and blood flow carries out heat exchange through the alternating temperature water outside alternating temperature fiber (14) endoporus and the alternating temperature fiber, and alternating temperature water advances from water inlet (3), and outlet (2) goes out.The blood flow inflow connection cover (12) of process alternating temperature carries out oxygenate by the channel of blood flow and the oxygenation membrane of oxygenator inner core (10), oxygen by gas access (6) enter contrary blood flow direction flow with blood oxygenation after, the carbon dioxide of remaining oxygen and discharge is discharged by gas outlet (4).Venous blood through the oxygenate that relents becomes arterial blood by blood outlet (5) outflow.
Characteristics of the present utility model are: simple in structure, and in being, thermode and oxygenator walk blood.The priming volume I satisfies the needs that toy (as rat) etc. is done the extracorporeal circulation experiment.
Description of drawings
Fig. 1 is this utility model example structure sketch map.
1 is the blood inlet among the figure, the 2nd, and outlet, the 3rd, water inlet, the 4th, gas access, the 5th, blood outlet, the 6th, gas outlet, the 7th, oxygenator end cap, the 8th, oxygenation membrane, the 9th, oxygenator shell, the 10th, oxygenator inner core, the 11st, sealing gasket, the 12nd, connection cover, the 13rd, thermode shell, the 14th, alternating temperature fiber, the 15th, thermode end cap, the 16th, thermode, the 17th, oxygenator.
The specific embodiment
With diameter is that 1080 of 0.3mm polypropylene screens make the oxygenator that effective length is 120mm, the long 140mm of oxygenator, diameter is 20mm, and the gas access 6 of oxygenator is driveed in the end, outlet 4 sides of opening at oxygenator, and the hollow-fibre membrane that weaves is looped around on the inner core of the about 20mm of diameter.With diameter is that the 1.0mm wall thickness is that 100 of the modified poly ethylene doughnuts of 0.1mm make the thermode that effective length is 110mm, the long 130mm of thermode, diameter 20mm.Water inlet 3, the outlet 2 of thermode are opened the same side at thermode, and thermode 16 is connected by connection cover 10 with oxygenator 17, and an end that makes thermode is as blood inlet 1, and the side of oxygenator is blood outlet 5.Doughnut is prior art with concrete processing technology such as polyurethane sealing, crop sealing, connection.
The oxygenator that the foregoing description obtains, its technical parameter is as follows:
Blood flow: 0.05-0.3L/min
Oxygenate area: 0.1m
2Oxygenation chamber priming volume: 6ml;
Alternating temperature coefficient: 0.5; Temperature-changing chamber priming volume: 6ml.
If change oxygenator, thermode size, i.e. the long 100mm of oxygenator, effective length 80mm, diameter 16mm, the long 100mm of thermode, diameter 16mm are with above-mentioned same method, and can obtain oxygenator is the zoopery membrane oxygenators such as mice of walking blood in external blood circulation, thermode are.
