The technical scheme that its technical problem that solves this utility model adopts is: the safe precision filter infusion set of this disposable use, comprise dropping funnel, the dropping funnel upper end connects flexible pipe by the dropping funnel loam cake, be provided with water in the flexible pipe and end switch, the flexible pipe end connects the bottle stopper sting device, the dropping funnel lower end is communicated with tube for transfusion by the dropping funnel lower cover, be provided with flow regulator and venoclysis needle on the tube for transfusion successively, it is characterized in that: described dropping funnel internal fixation one precision liquid medicine filter membrane, precision liquid medicine filter membrane circumference is connected with the tight heat seal of dropping funnel lower cover upper inside wall, dropping funnel lower cover bottom is provided with brace rod, and the precision liquid medicine filter membrane is supported in the brace rod upper end.The heat seal closely of precision liquid medicine filter membrane covers under dropping funnel, the slit that the no supplied gas of periphery is passed through.
Described precision liquid medicine filter membrane is the hydrophilic liquid medicine filtering membrane.Can change the liquid medicine filtering membrane in different medical filtrations aperture according to demand.
Described brace rod is two vertical planes that relative cross section is arc and the same center of circle.
Described brace rod is that many sliver transvers sections are the vertical plane of arc, and a plurality of vertical plane circle spacings are uniform.
Described dropping funnel lower cover is installed in the dropping funnel bottom, and dropping funnel lower cover top is filled in dropping funnel inside and closely is connected with the dropping funnel inwall, and dropping funnel lower cover lower central position is provided with infusion hole, and infusion hole is communicated with tube for transfusion.
Described dropping funnel loam cake covers in the dropping funnel upper end, covers on the dropping funnel and is provided with one or two inlet opening, inlet opening and soft pipe connection.
Compared with prior art, the beneficial effect that has of this utility model is:
1, precision liquid medicine filter membrane and the heat seal of dropping funnel lower cover are tight, but periphery does not have the slit that supplied gas is passed through, the precision liquid medicine filter membrane is the liquid medicine filtering membrane of possess hydrophilic property, gas is difficult to pass through, thereby the bubble of effectively having stopped to produce in the infusion process enters human body and realizes the secondary filter effect; After transfusion finishes, under the obstruct of precision liquid medicine filter membrane, the gas in the pipeline of liquid medicine filtering membrane lower end is difficult to penetrate precision liquid medicine and filters film formed enclosed space, thereby effectively prevents and avoid blood backflow phenomenon in the infusion process, safe and reliable, and effectively reduce the patient care difficulty;
2, the safe precision filter infusion set of this disposable use is simple in structure, and convenient production utilizes automatization's assembling to enhance productivity greatly, and be easy for operation, low cost of manufacture.
Description of drawings
Fig. 1 is the safe precision filter infusion set structural representation of this disposable use.
Fig. 2 is the safe precision filter infusion set partial enlarged drawing of this disposable use.
Fig. 3 is that the A-A of Fig. 2 is to cutaway view.
Wherein: 1, bottle stopper sting device 2, flexible pipe 3, water end switch 4, dropping funnel loam cake 5, dropping funnel 6, precision liquid medicine filter membrane 7, dropping funnel lower cover 8, tube for transfusion 9, flow regulator 10, venoclysis needle 11, brace rod.
The specific embodiment
Fig. 1 ~ 3rd, most preferred embodiment of the present utility model is described further below in conjunction with 1 ~ 3 pair of this utility model of accompanying drawing.
With reference to accompanying drawing 1, the safe precision filter infusion set of disposable use, comprise dropping funnel 5, dropping funnel 5 upper ends connect flexible pipe 2 by dropping funnel loam cake 4, be provided with water in the flexible pipe 2 and end switch 3, flexible pipe 2 ends connect bottle stopper sting device 1, and dropping funnel 5 lower ends are communicated with tube for transfusion 8 by dropping funnel lower cover 7, are provided with flow regulator 9 and venoclysis needle 10 on the tube for transfusion 8 successively.Dropping funnel loam cake 4 covers in dropping funnel 5 upper ends, dropping funnel loam cake 4 is provided with one or two inlet opening, inlet opening is communicated with flexible pipe 2, when inlet opening arranges one, bottle stopper sting device 1, flexible pipe 2 and the water of top end switch 3 cover are set, when inlet opening arranged two, the bottle stopper sting device 1 of top, flexible pipe 2 and water ended switch 3 two covers are set respectively, can insert two medicine bottles simultaneously; Dropping funnel lower cover 7 is installed in dropping funnel 5 bottoms, and dropping funnel lower cover 7 tops are filled in dropping funnel 5 inside and closely are connected with dropping funnel 5 inwalls, and dropping funnel lower cover 7 lower central positions are provided with infusion hole, and infusion hole is communicated with tube for transfusion 8.
