Utility model content
The intravenous transfusion device that provides a kind of patient of being convenient to oneself to change dressings is provided the purpose of this utility model, can overcome the existing transfusion device inconvenient defect of changing dressings, and technical solution adopted in the utility model is as follows:
A kind of intravenous injector, comprise bottle cork needle, air inlet pipe, dropper, flow regulator, liquid medicine filter, intravenous needle, infusion tube, described bottle cork needle, dropper, flow regulator, liquid medicine filter and intravenous needle connect successively by infusion tube, described bottle cork needle and intravenous needle are separately positioned on the two ends of infusion tube, described air inlet pipe is arranged on the connecting portion of bottle cork needle and infusion tube, described flow regulator is enclosed within on the infusion tube between dropper and liquid medicine filter, described dropper comprises body, body two ends be used as medicine mouthful and medicine outlet and being arranged on is used as medicine mouthful and medicine outlet between medicinal liquid switch, body is divided into upper and lower two parts by described medicinal liquid switch, described medicinal liquid switch comprises transfer strip and lower transfer strip, described upper transfer strip is fixedly installed in body, described lower transfer strip is rotationally connected by rotating shaft and upper transfer strip, described upper transfer strip and lower transfer strip are at least provided with a through hole, described lower transfer strip is provided with shifting block, on described body, the position of corresponding lower transfer strip is provided with semicircular notch, described shifting block stretches out from semicircular notch.
Preferably, described dropper is provided with two mouths that are used as medicine, described upper transfer strip is provided with two through holes, described lower transfer strip is provided with a through hole, in the top body of described dropper, be also provided with barrier sheet, top body is separated into two chambers in left and right by described barrier sheet, and two through holes of described upper transfer strip lay respectively in two chambers in left and right.
Preferably, the upper surface of described upper transfer strip is circular concave surface.
The beneficial effects of the utility model are: by medicinal liquid switch, patient can oneself change dressings, and has both reduced medical personnel's workload, can avoid again plugging the liquid medicine contamination that bottle cork needle causes, simple to operate, safe ready.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of dropper.
Fig. 3 is the partial schematic diagram of semicircular notch.
Fig. 4 is the process schematic diagram of changing dressings of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is illustrated.
As shown in Figure 1, a kind of intravenous injector, comprise bottle cork needle 1, air inlet pipe 2, dropper 3, flow regulator 4, liquid medicine filter 5, intravenous needle 6, infusion tube 7, bottle cork needle 1, dropper 3, flow regulator 4, liquid medicine filter 5 and intravenous needle 6 connect successively by infusion tube 7, bottle cork needle 1 and intravenous needle 6 are separately positioned on the two ends of infusion tube 7, air inlet pipe 2 is arranged on the connecting portion of bottle cork needle 1 and infusion tube 7, and flow regulator 4 is enclosed within on the infusion tube 7 between dropper 3 and liquid medicine filter 5.
As shown in Figure 2, dropper 3 comprises body 31, body 31 two ends be used as medicine mouthfuls 32 and medicine outlet 33 and being arranged on be used as medicine mouthfuls 32 and medicine outlet 33 between medicinal liquid switch 34, between medicinal liquid switch 34 and body 31 for being tightly connected, guarantee that extraneous air can not enter in dropper 3, and body 31 is divided into upper tube body 311 and lower tube body 312, medicinal liquid switch 34 comprises transfer strip 341 and lower transfer strip 342, upper transfer strip 341 is fixedly installed in body 31, lower transfer strip 342 is rotationally connected by rotating shaft 42 and upper transfer strip 341, rotating shaft 42 ends are provided with screw thread, upper transfer strip 341 is linked together with lower transfer strip 342, the part that rotating shaft 42 contacts with lower transfer strip 342 is smooth shaft, can make incision change sheet 342 rotates around rotating shaft 42.Dropper 31 is provided with two mouths 32 that are used as medicine, upper transfer strip 341 is provided with two through holes 35,36, lower transfer strip 342 is provided with a through hole 37, in upper tube body 311, be also provided with barrier sheet 38, upper tube body 311 is separated into two chambers 39,40 in left and right by barrier sheet 37, two through holes 35,36 of upper transfer strip 341 lay respectively in two chambers 39,40 in left and right, and the upper surface of upper transfer strip 341 is circular concave surface, is convenient to medicinal liquid and flows into lower tube body 312 from through hole 35,36 via through holes 37.
