Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail, can implement according to this with reference to description word to make those skilled in the art.
As shown in Figure 1, the invention provides a kind of self adaptation portable constant pressure transfusion device, comprise, working bladder 8, described working bladder 8 is provided with air inlet pipe, and described air inlet pipe is provided with pressure transducer 3 and venting valve 4; Control system 6, is electrically connected respectively with described pressure transducer 3 and described venting valve 4; Flow adjustment mechanism, comprises flow sensor 5 and flow control valve, and described flow sensor 5 and described flow control valve control by described control system 6; Wherein, described working bladder 8 and transfusion bag are with being put in the cavity 7 of fixed volume, and described flow sensor 5 is all located on the tube for transfusion of described transfusion bag with described flow control valve.Described control system 6 comprises input mechanism and circuit mechanism, and described input mechanism is man-machine control panel; Described circuit mechanism comprises signaling conversion circuit, single-chip microcomputer and output circuit, and described single-chip microcomputer is connected with described signaling conversion circuit and output circuit respectively and controls all circuit and runs.Described pressure transducer 3 is all electrically connected with described single-chip microcomputer by described signaling conversion circuit with described flow sensor 5; And described venting valve 4 is connected with described output circuit with described flow control valve.Described control system 6 is also connected with boom unit, and when flow sensor 5 influence value is lower than setting value, described control system 6 is closed described flow control valve and started described alarm device.Described air inlet pipe one end is connected on air storage bag 2, and described air storage bag 2 is connected by the first pipeline with inflatable ball 1, and described first pipeline is also provided with venting valve 4.Described flow sensor 5 can be held in transfusion bag outlet tube optional position by condensing tube tongs.Described cavity 7 points is done two-layer up and down by the built-in soft dividing plate of described cavity 7, working bladder 8 described in upper stratification, lower stratification transfusion bag.
