Description
Technical field
This utility model relates to medical apparatus and instruments, is specifically related to a kind of disposable transfusion device.
Background technology
Common disposable medical transfusion device does not have the blood return prevention function, when finishing, patient's transfusion causes blood back easily as if the untimely syringe needle that pulls out, there is Crinis Carbonisatus to understand that various blood return prevention disposable transfusion devices solve transfusion device blood back problem, but existing blood return prevention disposable transfusion device or complex structure cost height, or the blood return prevention effect is good inadequately, or is not easy to use.
The utility model content
The purpose of this utility model provides the disposable transfusion device that is provided with blood return prevention fluid-tight tube that a kind of cost simple in structure is low, blood return prevention is effective, easy to use.
Technical solution of the present utility model is: it comprises the infusion bottle plug, drip tube, control valve, filter and infusion needle, dripping tube links to each other with filter with the infusion bottle plug respectively by tube for transfusion, control valve is enclosed within on the tube for transfusion that drips between tube and the filter, infusion needle links to each other with filter, be provided with blood return prevention fluid-tight tube between an infusion bottle plug and the tube, blood return prevention fluid-tight tube is the airtight cylindrical shell that an end is provided with inlet and liquid outlet, being provided with an end in the blood return prevention fluid-tight tube is connected with liquid outlet, the drain pipe of other end opening, the inlet of blood return prevention fluid-tight tube and liquid outlet are connected with an infusion bottle plug and a tube by tube for transfusion respectively.
Technique effect of the present utility model is: it has the advantage that cost simple in structure is low, blood return prevention is effective, easy to use, and is safe in utilization, the reliability height.
Description of drawings
Accompanying drawing is this utility model embodiment axonometric chart.
The specific embodiment
As shown in the figure, it comprises infusion bottle plug 1, drip tube 2, control valve 3, filter 4 and infusion needle 5, dripping tube 2 links to each other with filter 4 with infusion bottle plug 1 respectively by tube for transfusion 6, control valve 3 is enclosed within on the tube for transfusion 6 that drips between tube 2 and the filter 4, infusion needle 5 links to each other with filter 4, special: as to be provided with blood return prevention fluid-tight tube 7 between an infusion bottle plug 1 and the tube 2, blood return prevention fluid-tight tube 7 is the airtight cylindrical shell that an end is provided with inlet 71 and liquid outlet 72, being provided with an end in the blood return prevention fluid-tight tube 7 is connected with its liquid outlet 72, the drain pipe 73 of other end opening, the inlet 71 of blood return prevention fluid-tight tube 7 and liquid outlet 72 are connected with an infusion bottle plug 1 and a tube 2 by tube for transfusion 6 respectively.Inlet 71 is provided with dropper 74 in the blood return prevention fluid-tight tube 7.The liquid outlet 72 of blood return prevention fluid-tight tube 7 by fall L shaped tube for transfusion 6 with drip tube 2 and be connected.
Medicinal liquid during normal infusion in the blood return prevention fluid-tight tube 7 drips tube 2 through drain pipe 73 from the bottom suction of blood return prevention fluid-tight tube 7 by siphonage, when the liquid level in the blood return prevention fluid-tight tube 7 is brought down below the outlet of dripping the tube dropper, medicinal liquid in the blood return prevention fluid-tight tube 7 can't be sucked out, siphonage stops, medicinal liquid forms fluid-tight in blood return prevention fluid-tight tube 7 lower ends, the liquid level that drips tube 2 inner liquid medicines continues to descend, confined space between liquid level and the fluid-tight forms negative pressure, negative pressure makes liquid level no longer continue to descend when the liquid level of tube for transfusion 6 inner liquid medicines drops to certain altitude, transfusion stops automatically, the human vein blood pressure can't be pressed into blood tube for transfusion 6 under the effect of medicinal liquid pressure, thereby realizes blood return prevention.
