The technical scheme in the invention for solving the above technical problem is: a kind of cardioplegic solution filling apparatus, include loam cake, housing, lower cover, the pipe external blood circulation is housed in the housing, the fiber tubular type alternating temperature film of leaking water in the pipe, it is characterized in that: on be covered with water inlet, under be covered with outlet, alternating temperature water is directly entered in the fiber tubular type alternating temperature film by water inlet, discharge from outlet after taking away heat, lower housing portion is provided with blood inlet, top is provided with blood outlet and air vent, blood, stop jumping liquid and enter in the filling apparatus housing, from bottom to top flow, discharge from blood outlet behind the alternating temperature by the gap that fiber tubular type alternating temperature is intermembranous from blood inlet.
The said lower housing portion inwall of this utility model is provided with an annular along blood inlet and leads the blood groove, like this, makes blood flow path lengthening, helps the dispersion that the housing inner blood advances blood, and makes that blood inlet and blood outlet blood flow have promoted the alternating temperature effect to opposite in the housing.
The said housing of this utility model top is provided with an annular gas collecting belt, and it is communicated with air vent.
The position of air vent is higher than the position of blood outlet on the said housing of this utility model, and like this, the gas after the separation can fully drain in exhaust ports, helps vim and vigour and separates.
The said blood outlet of this utility model front portion is provided with drainage screen, and the blood behind the alternating temperature flows into the perfusion pipeline through filter screen from blood outlet.
The said lower housing portion of this utility model is provided with a spare interface in 180 ° of directions of blood inlet.
This utility model adopts said structure, blood, stop jumping liquid from down and mobile, alternating temperature water from top to bottom flows, go with blood back flow, against existing technologies, the exchange heat medium is reverse to carry out, and improves the heat exchange effect, reduce blood flow resistance, reduced blood and foreign body contact area and priming volume.Air vent and blood outlet have certain height poor, and the gas that produces in gas in the preliminary filling process and the perfusion is drained by the air vent branch, have increased safety.This utility model structure is reasonable, compact conformation, and blood flow resistance is little; the heat transfer efficiency height, the alternating temperature effect is remarkable, and safety in utilization is good; simple to operate, aerofluxus, easy to connect, multiple functional; exhaust capacity is strong; alternating temperature is satisfactory for result, and blood cell damage is few, and it is little that blood gives charge; the myocardial preservation effect is obvious, and reasonably blood flow direction and filtering function greatly facilitate clinical perfusion's teacher work.It is applicable to that open heart operation with extracorporeal circulation makes the cardiac arrest perfusion, is applicable to that also other histoorgan protection perfusion uses.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
1. loam cakes among the figure, 2. housing, 3. lower cover, 4. blood inlet, 5. blood outlet, 6. temperature-measuring port, 7.PU shutoff glue, 8. drainage screen, 9. fiber tubular type alternating temperature film, 10. water inlet, 11. outlet, 12. spare interface, 13. air vents, 14. annulars are led the blood groove, 15. annular gas collecting belts.
The specific embodiment
As can be seen from Figure 1, a kind of cardioplegic solution filling apparatus of this utility model includes loam cake 1, housing 2, lower cover 3 etc., and the fiber tubular type alternating temperature film 9 of leaking water in pipe external blood circulation, the pipe is housed in the housing 2.Loam cake 1 is tightly connected with housing 2, and lower cover 3 is tightly connected in housing 2 bottoms and housing 2.Loam cake 1, housing 2, lower cover 3 etc. are the PC transparent material, the blood flow clear route, are easy to observe.Fiber tubular type alternating temperature film 9 two ends PU shutoff glue 7 shutoff in the housing 2, two ends form shutoff face, in order to isolate cooling-water duct and blood, to stop jumping the liquid passage.Gap between fiber tubular type alternating temperature film 3 pipes is for walking haemocoele.Described alternating temperature material is a fiber tubular type alternating temperature film, adopts the form of leaking water in pipe external blood circulation, the pipe, and the alternating temperature effect is obvious.During use, the fiber tubular type alternating temperature film 9 that is coiled into tubular is packed in the filling apparatus housing 2.With PU shutoff glue 7 shutoff filling apparatus housings 2 two ends, make it to form shutoff face, so that water stream channel and blood channel are isolated.
