Description
Technical field
This utility model relates to a kind of medical apparatus, specifically a kind of accurate blood transfusion apparatus.
Background technology
At present, clinical when giving patients with transfusion, employing be conventional blood exchange transfusion set, comprise needle for inserting bottle, puncture needle and murphy's dropper, during massive transfusion, because blood source is different, its RH factor of blood plasma that blood group is identical is not necessarily identical, so, after hanging one bag of blood plasma, need with the not luxuriant and rich with fragrance dropper of normal saline washing, after whole not luxuriant and rich with fragrance dropper rinses, then connect next bag of blood plasma, pull and push back and forth and easily pollute and strengthen medical personnel's workload; During infant blood transfusion, the blood volume of input is less, and needs very accurate, and blood transfusion does not reach therapeutic effect at least, and overtransfusion then can increase the weight of its heart burden, strictly must control transfusion volume; The blood vessel of infant is comparatively thin, when there is platelet, leukocyte, fibrin gathering in blood, probably causing syringe needle to block thus causing blood transfusion not smooth.
Utility model content
The purpose of this utility model is to provide a kind of accurate-metering transfusion volume, without the need to repeatedly plugging, can not causing the accurate blood transfusion apparatus of filter and syringe needle blocking, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of accurate blood transfusion apparatus, comprise bottle cork needle, drop bottle, four-way pipe, murphy's dropper, flow regulator, filter and venipuncture needle, described murphy's dropper top is connected with four-way pipe, each arm of four-way pipe is connected to drop bottle, described drop bottle is labeled with metering scale, described drop bottle is connected with bottle cork needle, described murphy's dropper upper end is provided with drip nozzle, it is the filter membrane that 60 degree of angles are arranged that middle part is placed with horizontal direction, described murphy's dropper bottom is connected with flexible pipe, flexible pipe is provided with flow regulator, the flexible pipe other end is connected with filter, described filter is connected with venipuncture needle.
As further program of the utility model: described drop bottle is provided with air filter.
As this utility model further scheme: described bottle cork needle and venipuncture needle are provided with protective sleeve.
As this utility model further scheme: each arm of described four-way pipe is also provided with control valve.
Compared with prior art, the beneficial effects of the utility model are: this utility model structure is simple, easy to use, to be punctured respectively normal saline bottle by three bottle cork needles, bags of blood and ampoule, drop bottle is carved with metering scale, dosing in transfusion procedure can be realized simultaneously, dilution, the function of blood volume metering, accurate-metering transfusion volume, effectively avoid repeatedly plugging, decreasing pollution probability, each arm is provided with control valve, independently can adjust and control each arm flow, the filter membrane in 60 degree of overturning angles is provided with in murphy's dropper, compared with flat placed type filter membrane in prior art, increase the contact area between filter membrane and blood, the platelet that can better excessively assemble in filtering blood, leukocyte and fibrin, deposit on filter membrane can be washed the low side to filter membrane under the drive of action of gravity and blood flow effect, avoid filter membrane or the blocked and not smooth situation of blood transfusion of syringe needle, microgranule after the filter that venipuncture needle place connects can filter bottle stopper lancet puncture bottle stopper in the microgranule that produces and normal saline, good filtration effect, transfusion generally can be continued after patient transfuses blood, due to the effect of filter after normal saline flushing flexible pipe, the control valve directly can opening the arm place be connected with ampoule is patient infusion, thus change transfusion device without the need to plug again.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of accurate blood transfusion apparatus, comprise bottle cork needle 1, drop bottle 2, four-way pipe 3, murphy's dropper 4, flow regulator 5, filter 6 and venipuncture needle 7, described murphy's dropper 4 top is connected with four-way pipe 3, each arm of described four-way pipe 3 is also provided with control valve 12, each arm of four-way pipe 3 is connected to drop bottle 2, described drop bottle 2 is labeled with metering scale, described drop bottle 2 is provided with air filter, described drop bottle 2 is connected with bottle cork needle 1, described murphy's dropper 4 upper end is provided with drip nozzle 8, it is the filter membrane 9 that 60 degree of angles are arranged that middle part is placed with horizontal direction, described murphy's dropper 4 bottom is connected with flexible pipe 10, flexible pipe 10 is provided with flow regulator 5, flexible pipe 10 other end is connected with filter 6, described filter 6 is connected with venipuncture needle 7, described bottle cork needle 1 and venipuncture needle 7 are provided with protective sleeve 11.
Operation principle of the present utility model is: the protective sleeve pulling out bottle cork needle 1, bottle cork needle is inserted blood bag, blood gravity flow enters band and indicates in the dropper 2 of scale, when blood liquid level arrives required transfusion volume scale, clamping blood bag opening part, the bottle cork needle 1 of another arm punctures normal saline bottle, open control valve 12, with normal saline pre-flush infusion tube 10, after rinsing twice, close flow regulator 5, being punctured into by venipuncture needle 7 treats in the vein blood vessel of blood donor, open flow regulator 5 and be adjusted to suitable flow velocity, then the control valve 12 of blood transfusion arm is opened, can select close or turn normal saline flow down according to haemoconcentration situation, blood flows into murphy's dropper 4 by four-way pipe 3, the platelet of excessive aggregation in blood is filtered out under the effect of filter membrane 9, leukocyte and fibrin, keep filter 6 and vein puncture needle head 7 not blocked, stop to transfuse blood not smooth situation, microgranule in the microgranule that filter 6 produces after can filtering bottle cork needle 1 piercing vials and normal saline, after blood transfusion terminates, continue the flushing tube for transfusion that has an intravenous drip of physiological saline, then the control valve 12 with ampoule connecting branch is opened, continue loading liquid, avoid plug blood exchange transfusion set repeatedly, decrease pollution probability
