in order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides an annular prevents blockking up extrinsic cycle diversion pipeline, includes the body, be equipped with the toroidal tube on the body, the toroidal tube includes first route and second route, first route with the second route with the body is the Y type and connects, first route with all be equipped with detachable filter screen subassembly on the second route, filter screen subassembly both sides first route with all be equipped with the ooff valve on the second route.
Atrium and heart-lung machine are connected respectively to the both ends of body and are carried out the blood drainage, the ooff valve is used for controlling first passageway with the break-make of second route to select the drainage route according to actual conditions, the filter screen subassembly is used for filtering the impurity of great granule in the blood, prevents the jam takes place for the body, works as when the filter screen subassembly needs the clearance, through the ooff valve closes and corresponds first passageway perhaps the second route carries out the drainage through another route, needs the clearance the filter screen subassembly can be pulled down alone, need not to pull down whole the body, does not influence the drainage and normally goes on, the back reload of clearance is gone up the filter screen subassembly can finish.
Further, the filter screen subassembly includes the coupling of double-end internal thread formula and sets up filter screen in the coupling, the coupling with first passageway with second passageway threaded connection, the coupling is used for connecting first passageway with the second passageway, the thread sealing's mode can be guaranteed to connect closely, prevents to take place blood and leaks, and conveniently will first passageway with the second passageway is opened, is convenient for take off the coupling with the filter screen is cleared up.
Furthermore, the switch valve is a butterfly valve, and the butterfly valve controls the switch through the rotation of the valve core, so that the phenomenon that the blood is gathered and coagulated due to the slowing of the flow velocity in the butterfly valve can be prevented, and the blockage is avoided.
Further, the filter screen with for dismantling between the coupling and being connected, the filter screen can be followed alone the change is pulled down on the coupling, and the health is guaranteed to the disposable aseptic filter screen of convenient to use.
Further, the annular pipe is transparent flexible plastic pipe, the coupling is transparent rigid plastic material, is convenient for observe the annular pipe with the flow state of blood in the coupling with the filtration state of filter screen does benefit to in time changing the filter screen.
(III) the beneficial effects are as follows:
compared with the prior art, the utility model discloses the beneficial effect who produces is: through set up the ring conduit on the body, the ring conduit includes first passageway and second passageway, first passageway and second passageway are the Y type with the body and are connected, all set up detachable filter screen subassembly on first passageway and the second passageway, filter screen subassembly both sides set up the ooff valve, can select the drainage passageway as required in carrying out atrium drainage extracorporal circulatory system in-process, the filter screen subassembly that needs the clearance can be pulled down alone, need not to pull down whole body, do not influence the drainage and normally go on, effectively improve drainage efficiency and prevent blockking up the effect.
