Abstract
The utility model relates to a medical pumping injector comprising an injector, a guiding tube connected with an injecting head of the injector, wherein a triplet is arranged on the guiding tube, a main port of the triplet is communicated with an injecting port of the injector through the guiding tube, two branch ports of the triplet are connected with a tapered joint through the guiding tube, a one-way valve is respectively arranged between the tapered joint and the triplet, liquid which flows through the one-way valves has reverse current directions, and the pumping and the injecting of the injector can be realized through connecting the triplet on the injector, the liquid can be pumped or medicine liquid can be injected by multiple times without drawing out the guiding tube, and the device has the advantages of simple structure, convenient operation and use, high working efficiency, low cost and high safety efficiency.
Description
Technical field
This utility model relates to a kind of pump, specifically a kind of medical pump.
Background technology
At present, in the diagnosis of disease, in the treatment and the process of pathological analysis, extracting, collect relevant liquid out, or inject medicinal liquid, is one of the analytical test of being correlated with and main means of treatment.Generally adopt ordinary syringe to extract liquid out now clinically or inject medicinal liquid,, bring gas on one's body into easily like this, cause foreign body or cross infection the patient because the capacity limit of ordinary syringe often needs repetitious operation.Separately carry out with the injection Pharmaceutical owing to extract liquid out, need many syringes just can finish, make medical cost height, operation is also inconvenient.
Summary of the invention
It is low that the purpose of this utility model provides a kind of cost.Easy to operate, as can to take out simultaneously, annotate medical pump.
For achieving the above object, this utility model is by the following technical solutions:
Medical pump described in the utility model, comprise syringe, the conduit that is connected with the injection head of syringe, on the described conduit threeway is installed, main mouthful of threeway is communicated with the injection port of syringe by conduit, two branch mouths of threeway are connected with cone joint by conduit, are respectively equipped with check valve between cone joint and the threeway, and the flow direction of the liquid of the described check valve of process is opposite.
As a kind of improvement, described cone joint is provided with helmet.
Owing to adopted technique scheme, described medical pump, by on syringe, connecting a threeway, realize taking out, annotating of syringe, can be under the situation of not extracting conduit out, repeatedly extract liquid out or inject medicinal liquid, simple structure, operation, easy to use, high efficiency, cost is low, the security effectiveness height.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of this utility model.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Medical pump, comprise syringe 1, the conduit 2 that is connected with the injection head of syringe 1, on the described conduit 2 threeway 3 is installed, main mouthful of threeway 3 is communicated with the injection port of syringe 1 by conduit 2, two branch mouths of threeway 3 are connected with cone joint 4 respectively by conduit 2, promptly an end is connected with syringe 1 by conduit 2, the other end is provided with two branch mouths, be connected with conduit respectively, be respectively equipped with check valve 5 between cone joint 4 and threeway 3, the flow direction of the liquid of the described check valve 5 of process is opposite, a control injecting fluid, liquid is extracted in a control out.Two cone joints 4 can connect pricker or drainage tube, thereby can realize injection and drawing liquid to human body.Described cone joint 4 is provided with helmet 6, prevents that cone joint 4 from damaging and infection.
Claims (2)
1, medical pump, comprise syringe (1), the conduit (2) that is connected with the injection head of syringe (1), it is characterized in that: threeway (3) is installed on the described conduit (2), main mouthful of threeway (3) is communicated with the injection port of syringe (1) by conduit (2), two branch mouths of threeway (3) are connected with cone joint (4) respectively by conduit (2), are respectively equipped with check valve (5) between cone joint (4) and the threeway (3), and the flow direction of the liquid of the described check valve of process (5) is opposite.
2, medical pump according to claim 1 is characterized in that: described cone joint (4) is provided with helmet (6).
