Description
Technical field
This utility model relates to a kind of medical apparatus and instruments of the use of infusing, especially a kind of for intravenous infusion set dropper.
Background technology
Drip intravenous injection is due to easy to operate, and medicine directly enters blood, and therefore quick result is one of conventional medical procedure of hospitalize patient.But in clinical practice, often need the many bottle liquid medicines of a shot, this just needs medical personnel after a bottle liquid medicine, to change another bottle of continuation injection having injected, need bottle cork needle to extract and change medicinal liquid, insert in another medicine bottle, both increased medical personnel's working strength, increased again medicinal liquid by the chance of airborne courses of infection, and medicine bottle hangs over higher position mostly, patient oneself is also inconvenient to change dressings.
Utility model content
The purpose of this utility model is to provide a kind of intravenous transfusion device dropper of conveniently changing dressings, and 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 dropper, comprise body, described body upper end is provided with two mouths that are used as medicine, lower end is provided with a medicine outlet, described being used as medicine, is provided with medicinal liquid switch between mouth and medicine outlet, body is divided into upper and lower two parts by described medicinal liquid switch, described medicinal liquid switch comprises transfer strip, lower transfer strip and pallet, described upper transfer strip is fixedly installed in body, in the middle of described pallet, have the notch that connects upper lower tube body, described notch top is provided with step, described lower transfer strip is stuck on step and can on step, slidably reciprocates, on described inboard wall of tube body, be also provided with snap ring, described pallet is fixed in body by snap ring, described lower transfer strip is flexibly connected with upper transfer strip by pallet, on described upper transfer strip and lower transfer strip, be at least provided with a through hole, on described lower transfer strip, be also provided with push-pull bar, described push-pull bar protruded tube external body.
Preferably, in the upper tube body of described dropper, be provided with barrier sheet, upper tube body is separated into two chambers in left and right by described barrier sheet, and described upper transfer strip is provided with two through holes, described two through holes lay respectively in two chambers in left and right, and on described lower transfer strip, the position of corresponding notch is provided with two through holes.
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 pallet.
Fig. 3 is the structural representation of lower transfer strip.
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 dropper, comprises body 1, body 1 upper end is provided with two mouths 2 that are used as medicine, lower end is provided with a medicine outlet 3, is used as medicine and is provided with medicinal liquid switch 4 between mouth 2 and medicine outlet 3, and body 1 is divided into upper tube body 11 and lower tube body 12 by medicinal liquid switch 4.In upper tube body 11, be also provided with barrier sheet 5, upper tube body 11 is separated into two chambers 111,112 in left and right by barrier sheet 5.Medicinal liquid switch 4 comprises transfer strip 41, lower transfer strip 42 and pallet 43, on body 1 inwall, be also provided with snap ring 6, upper transfer strip 41 is fixedly installed in body 1, and pallet 43 is fixed in body 1 by snap ring 6, and lower transfer strip 42 is flexibly connected with upper transfer strip 41 by pallet 43.Upper transfer strip 41 is provided with two through holes 411,412, lower transfer strip 42 is provided with two through holes 421,422, two through holes 411,412 of upper transfer strip 41 lay respectively in two chambers 111,112 in left and right, the upper surface of upper transfer strip 41 is circular concave surface, lower transfer strip 42 is provided with push-pull bar 423, and push-pull bar 423 stretches out the outside of body 1.
As shown in Figure 2 (a) and (b), have the notch 431 that connects upper tube body 11 and lower tube body 12 in the middle of pallet 43, notch 431 tops are provided with step 432.
As Fig. 3 (a) with (b), lower transfer strip 42 is arranged on the step 432 of pallet 43, and can slidably reciprocate along step 432, the through hole 421,422 on lower transfer strip 42 is corresponding with the position of notch 431, so that medicinal liquid via through holes 421,422 and notch 431 flow in lower tube body 12.
As shown in Figure 4 (a), when start injection, through hole 411 aligns with through hole 421, and medicinal liquid can only enter dropper 1 lower tube body 12 through the passage between through hole 411 and through hole 421, and then enters human body; While changing dressings, push-pull bar 422 is shifted onto to the opposite side of body 1, as shown in Figure 4 (b), through hole 412 is alignd with through hole 422, now medicinal liquid will enter lower tube body 12 through the passage between through hole 412 and through hole 422, and then enters human body, just can be realized and changing dressings by above simple action.
This utility model is by medicinal liquid switch, and 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.
It should be noted that; above-mentioned explanation is not to restriction of the present utility model; this utility model is also not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those of ordinary skill in the art makes in essential scope of the present utility model, within all should being covered by protection domain of the present utility model.
