The specific embodiment
Below in conjunction with Fig. 1-Figure 14 this utility model is specified, upper conduit 1 links to each other with observing tube 2, observing tube is with annular colored medicinal liquid face graduation mark 9 outward, sealed ball float 8 is housed in the observing tube 2, observing tube 2 is communicated with tee T 4 upper binding head 4-1 by lower port 2-2, and the lower union joint 4-2 of tee T 4 links to each other with downcomer 6; Horizontal siphunculus 4-4 is communicated with the inner shell chamber 5-3 cavity of chamber of septum 5 by threeway connection mouth 5-1, and diaphragm 5-5 is housed in the chamber of septum 5, and diaphragm 5-5 separates inner room shell 5-3 and mistress's shell 5-4 inner chamber, and mistress's shell 5-4 is connected with warner by alarm connection mouth 5-2; Scale flow control valve 7 is enclosed within downcomer 6 adjusted infusion flows.There is scale area 7-3 in scale flow control valve 7 fronts, and there is scale reading district 7-4 two sides, and demarcate and is the length scale in the reading district of a side, demarcate to dripping fast scale after the reading district of a side measures through standard state; The liquid edema caused by disorder of QI of downcomer termination links to each other with downcomer 6 by downcomer connection tube 10-2-1 from filter tube 10, links to each other with needle catheter 11 by needle catheter connection mouth 10-2-6.
Embodiment: as shown in Figure 1, in actual use, the nurse enters medicine bottle with the tube for transfusion puncture, open scale flow control valve 7, after medicinal liquid is introduced into tube for transfusion, carry out the tube for transfusion aerofluxus, observing the tube for transfusion inner liquid medicine flows, after treating that piercing needle has the medicinal liquid smooth outflow, close scale flow control valve 7, patient is carried out venipuncture.Work before this and use the common transfusion pipe identical.After the venipuncture, the nurse gently breaks the downcomer connection tube 10-2-1 of hydrodynamic edema caused by disorder of QI from filter tube 10 off with the fingers and thumb with have gentle hands, downcomer connection tube 10-2-1 promptly breaks apart from filter chamber feed tube 10-2-5, under the elastic reaction of bellows 10-1-2, the liquid edema caused by disorder of QI becomes big from capsule 10-1 cavity, be full of medicinal liquid in the blister cavities, reserved the scale position of scale flow control valve 7, patient begins normal infusion.
When sneaking into several bubble once in a while because of carelessness in the tube for transfusion downcomer 6, bubble descends with medicinal liquid, and enters into separating liquid medicine filter tube 10 inside; Because downcomer connection tube 10-2-1 does not directly communicate with filter chamber feed tube 10-2-5, bubble enters the liquid edema caused by disorder of QI in capsule 10-1 the time, atmospheric density is littler than medicinal liquid, bubble rises to the liquid edema caused by disorder of QI rapidly and is stored in bubble storage area 10-3 from capsule 10-1 top, and can not enter filter chamber 10-2, just can not enter needle catheter 11 yet, play the effect of air and separating liquid medicine.When band is torn at patient's needle catheter 11 on one's body, needle catheter 11 may be towards all directions, because inlet opening 10-2-8 is positioned at the central authorities of liquid edema caused by disorder of QI from capsule 10-1, no matter where needle catheter is towards, the bubble inlet opening of all having no chance to enter, but being in the upper position of liquid edema caused by disorder of QI all the time from capsule 10-1, the liquid edema caused by disorder of QI under the different conditions is air storage location such as Figure 12, Figure 13, shown in Figure 14 in capsule 10-1.
When using this utility model transfusion to be near completion, when treating that the interior medicinal liquid of upper tubing drips off, the medicinal liquid face leaves the medicinal liquid face graduation mark of observing on the ball 9 to begin to descend, the sealed ball float 8 that swims on the medicinal liquid face also descends thereupon, medicinal liquid in observing tube 2 is near having flowed, sealed ball float 8 is just identical with the sealing ring 3 of 2-3 lower end, funnel-form bottom, the gravity of sealed ball float 8 itself and the elasticity of sealing ring 3 form sealing, air and following tee T 4 have been blocked, the contact of downcomer 6 herb liquids, make the pressure in the downcomer 6 reach balance, medicinal liquid no longer continues to descend, having finished the automatic cut-off medicinal liquid descends, prevent the function of blood back, the state after identical is as shown in Figure 2 to observing tube 2 bottoms and sealing ring 3 for sealed ball float 8 times.This utility model after medical personnel once set transfusion speed, can navigate to original transfusion speed according to the calibration data on the scale flow control valve 7 after changing liquid easily when using separately.This utility model is to infuse warner when being used in combination, air pressure among the horizontal siphunculus 4-4 finishes back variant with transfusion during infusing, diaphragm 5-5 by chamber of septum 5 inside, can sensed pressure change, and by with warner connection mouth 5-2 on the capillary vessel that is connected, the pressure variation is passed to warner, accurately and timely realize alarm, reach prompting medical personnel's purpose.
When manufacturing, sealed ball float 8 is packed into by observing tube 2 lower port 2-2 in the observing tube, then sealing ring 3 is installed to sealing ring erecting bed 2-4 position; The diameter of sealed ball float 8 is greater than sealing ring 3 internal diameters but less than sealing ring erecting bed 2-4 internal diameter, to guarantee to pack into observing tube 2 and can coincideing with sealing ring 3; Tee T 4, chamber of septum 5 fit together after making respectively, connect observing tube 2 and downcomer 6.The liquid edema caused by disorder of QI is identical with before common transfusion pipe from the filter chamber of filter tube 10 part, filter chamber inner shell 10-2-2 and medicinal liquid feed tube 10-2-5, the integrated manufacturing of downcomer connection tube 10-2-1, the liquid edema caused by disorder of QI is from the integrated manufacturing of capsule 10-1, then the heat seal mouth 10-1-3 of liquid edema caused by disorder of QI from capsule 10-1 is connected with the shell heat seal of filter chamber 10-2, behind the compresses bellows telescoping tube 10-1-2 connection mouth 10-1-4 and downcomer connection tube 10-2-1 is connected and fixed.
