Abstract
The utility model relates to a microinjection pump for children. The microinjection pump for children comprises a pump body, two injectors and an extension tube, wherein two pushers are arranged on the pump body; each injector comprises an injector body and a push rod; each injector body is fixed on the pump body; a lockable liquid inlet is arranged at the front end of each injector body; the terminal end of each push rod is connected to each pusher; a corrugated flexible tube is sleeved outside each push rod; one end of each corrugated flexible tube is fixedly connected to the back end of each injector body while the other end thereof is fixedly connected to the back end of each pusher; the extension tube is detachably installed at the front end of the injector body of one injector and is provided with a flow controller and a liquid separation tube; one end of the liquid separation tube is connected to an initial section of the extension tube and is provided with a single-way ball valve at a joint; the other end of the liquid separation tube is connected to a liquid inlet at the front end of the injector body of the other injector, and the front end of the injector is blocked off by a sealing cap. The microinjection pump for children overcomes the disadvantages that the push rods of existing microinjection pumps are polluted easily and self-refitting is necessary for dual control, and is particularly suitable for infusing trace medicines at a constant speed for a long time during the pediatric nursing process in a hospital.
Description
Technical field
This utility model relates to a kind of pediatric nursing Special medical equipment, particularly a kind of children's's micro-injection pump.
Background technology
Existing micro-injection pump is more often used the 60mL syringe, while being applied to pediatric nursing, contains the general excess of dose; In addition, transfusion speed is generally 2-5ml/h, and one group of liquid is wanted 12-15h usually, and transfusion time is long, and injector push-rod open-assembly time in air of extracting state is also long, easily causes injector push-rod to pollute.Simultaneously, the existing matching used extension tube of micro-injection pump does not have flow controller, the simple propeller control medicinal liquid feeding rate that relies on, therefore the pediatric nursing personnel often will coordinate trace pump syringe to use after the general infusion set repacking, but the repacking of general infusion set need to be used sterile scissors that the upper part of Murphy's burette is cut off, then the broken ends of fractured bone is connected with the syringe body, the process of not only complex operation, and pruning transfusion device has increased its contaminated probability undoubtedly.
The utility model content
The technical problems to be solved in the utility model is the above-mentioned defect that how to overcome prior art, and a kind of children's's micro-injection pump is provided.
For solving the problems of the technologies described above, this children's micro-injection pump comprises a pump housing, two syringes and an extension tube, and the described pump housing is provided with two propellers; Described syringe comprises body and push rod, wherein body is fixed on the pump housing, its front end is provided with a closed inlet, the push rod end is connected on propeller, described push rod outer cover is provided with corrugated flexible hose, this corrugated flexible hose one end is fixedly connected on the body rear end, and the other end is fixedly connected on the propeller rear end; The detachable wherein body front end of a syringe that is arranged on of described extension tube, this extension tube is provided with flow controller and separating tube, described separating tube one end is connected to an extension tube initial segment, and be provided with non-return valve in junction, the other end is connected on the inlet of body front end of another syringe, and in a sealing cap shutoff for this syringe front end.
So design, at the outside sheathed corrugated flexible hose of push rod, overcome transfusion time long, and injector push-rod open-assembly time in air of extracting state is also long, the defect that easily causes injector push-rod to pollute; Flow controller is set on extension tube, has realized the dual control of flow, make the pediatric nursing personnel often will prune voluntarily the repacking general infusion set; Set up isocon, while making the flow controller current limliting, the unnecessary medicinal liquid extruded is delivered to another syringe, avoided the waste of medicinal liquid.
As optimization, the described pump housing is provided with flow, flow velocity display screen.So design, be convenient to the nursing staff and observe flow and flow velocity.
As optimization, described syringe is the 40mL syringe.So design, to adapt to the pediatric nursing special use.
This utility model children's micro-injection pump is simple in structure, easy to use, overcome the easy pollution of existing micro-injection pump push rod and dual control and need to reequip voluntarily the defect that former parts are realized, be particularly useful for the at the uniform velocity administration of long-time trace in the pediatric hospital nursery work.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model children's micro-injection pump is described further:
Fig. 1 is the planar structure schematic diagram (in figure, solid line is partly visible structure, and dotted portion is perspective structure) of this children's micro-injection pump.
