Abstract
A can anti-tampon blocking pipeline and reduce the extracorporeal circulation blood circuit of losing blood, tremulous pulse kettle and the venous chambers profile of this extracorporeal circulation blood circuit are designed to trapezoidal shape, the upper end of tremulous pulse kettle and venous chambers is made to be less than lower end, one end that blood flows to kettle body is less, one end that blood flows out kettle body is larger, the filter screen of a serpentine is devised respectively in the tremulous pulse kettle of extracorporeal circulation blood circuit and the kettle body of venous chambers, the aperture of this filter screen is the square aperture of 1mm, the thrombosis formed during hemodialysis is once come off, can fall on serpentine filter screen or slide into the bottom of filter screen along serpentine filter screen, and tremulous pulse kettle and venous chambers can not be blocked, if thrombosis drops to the bottom of kettle body through filter screen, because the design of kettle body upper and lower side size is different, larger bottom kettle body, the thrombosis dropped also can not block tremulous pulse kettle and venous chambers completely.
Description
One, technical field
This utility model relates to Dialysis tubing road technique field, the extracorporeal circulation blood circuit of especially hemodialysis.
Two, background technology
When hemodialysis, the blood in patient body causes external after cleansing filter again in defeated ex vivo by hemodialysis extracorporeal circulation blood circuit.Therefore, this device is mainly used in setting up extracorporeal circulation of blood.Tremulous pulse kettle and the venous chambers of conventional extracorporeal circulation blood circuit are the cylindricality of hollow or single inverted trapezoidal structure, tremulous pulse kettle bottom is only had to have a conical screen, for preventing the thrombosis blocking pipeline formed in hemodialysis process, but at clinical discovery, once after larger thrombosis comes off drop to conical screen from the top of tremulous pulse kettle or venous chambers, be easy to total blockage pipeline, cause patient to lose blood.
Three, summary of the invention
In order to overcome the deficiency that existing extracorporeal circulation blood circuit easily causes thrombosis to block, this utility model provides a kind of extracorporeal circulation blood circuit, and it can make to be unlikely to bottom total blockage tremulous pulse kettle and venous chambers during thrombus breaks loose, thus reduces unnecessary losing blood.
This utility model solves the technical scheme that its technical problem adopts: the filter screen devising a serpentine in the tremulous pulse kettle of extracorporeal circulation blood circuit and the kettle body of venous chambers respectively, the aperture of this filter screen is the square aperture of 1mm, the kettle body upper end of tremulous pulse kettle and venous chambers is less than lower end, namely one end kettle body of flowing to of blood is less, one end kettle body that blood flows out is larger, the thrombosis formed during hemodialysis is once come off, the bottom of filter screen can be slided into along serpentine filter screen, , and tremulous pulse kettle and venous chambers can not be blocked, if thrombosis drops to the bottom of kettle body through filter screen, because the design of kettle body upper and lower side size is different, larger bottom kettle body, the thrombosis dropped also can not block tremulous pulse kettle and venous chambers completely.
Four, accompanying drawing explanation
Fig. 1 is this utility model structure chart, wherein 1, tremulous pulse kettle, and 2, venous chambers, 3, arterial end flexible pipe, 4, vein end flexible pipe, 5, serpentine filter screen, 6, upper end, 7, lower end
Five, detailed description of the invention
In FIG, the tremulous pulse kettle (1) of extracorporeal circulation blood circuit and the upper end (6) of venous chambers (2) are less than lower end (7), in a trapezoidal shape, a serpentine filter screen is devised respectively in tremulous pulse kettle (1) and venous chambers (2), the generation of situation of losing blood when such design decreases thrombosis, ensure that thrombosis is unlikely to complete blocking pipeline.
Claims (1)
1. an extracorporeal circulation blood circuit, it is characterized in that extracorporeal circulation blood circuit tremulous pulse kettle and venous chambers profile are trapezoid, namely the upper end of tremulous pulse kettle and venous chambers is less than lower end, the filter screen of a serpentine is devised respectively in the kettle body of tremulous pulse kettle and venous chambers, the aperture of this filter screen is the square aperture of 1mm, the thrombus breaks loose formed during hemodialysis is to filter screen, filter screen bottom can be slided into along serpentine filter screen, , and the bottom of tremulous pulse kettle and venous chambers can not be dropped to, if thrombosis drops to the bottom of kettle body through filter screen, because kettle body is designed to trapezoid, larger bottom kettle body, the thrombosis dropped also is unlikely to block tremulous pulse kettle and venous chambers completely.
