Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of medical threeway pump.
Background technology
As everyone knows, in medical diagnosis on disease, treatment, in the pathological analysis process, extract, collect relevant body fluid out, or inject medicinal liquid, analytical test of being correlated with and treatment are the important means of using always.At present, generally adopt ordinary syringe to extract body fluid or injection medicinal liquid out, because the capacity limit of ordinary syringe often needs repetitious operation, the easy like this gas of bringing in patient body causes foreign body or cross infection.And to extract body fluid out and inject medicinal liquid generally be separately to carry out, need just can finish with many syringes, and medical cost up, operation is also inconvenient.Patent 02214581.8 has been announced a kind of medical threeway pump, it is provided with syringe, threeway, conduit, check valve, cone joint, threeway connects syringe and two cone joints by conduit, be provided with check valve between cone joint and the threeway, the control flow direction of two check valves is respectively dorsad and enters threeway.But continuous uninterrupted is extracted body fluid out or is injected medicinal liquid, but when extracting body fluid out and adding the conversion of medicinal liquid function, operation is still inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple structure is provided, and cost is low, operation, easy to use, the medical threeway pump that security performance is good.
The technical scheme in the invention for solving the above technical problem is: a kind of medical threeway pump, it includes syringe, conduit, joint, it is characterized in that: also be provided with three-way valve, three-way valve connects syringe and feed liquor conduit respectively, goes out fluid catheter by joint, feed liquor conduit and go out the fluid catheter other end and also be respectively equipped with joint.
Also be provided with liquid stopping clamp on this utility model feed liquor conduit.The feed liquor conduit, go out to be respectively equipped with on the fluid catheter conduit mark card.
This utility model is owing to adopt three-way valve to connect syringe and two conduits, by regulating the three-way valve conducting, control take out beam to, can under the situation of not extracting drainage tube and syringe, repeatedly extract body fluid continuously out or inject medicinal liquid.This utility model simple structure, operation, easy to use, high efficiency, cost is low, and security performance is good.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
1. syringes among the figure, 2. female cone joint, 3. three-way valve, 4. liang pass joint 5. goes out fluid catheter, 6. mark card, 7. liang pass joint, 8. helmet, 9. female cone joint, 10. liquid stopping clamp, 11. feed liquor conduits, 12. mark cards, 13. outer cone joints, 14. helmets.
The specific embodiment
As can be seen from Figure 1, a kind of medical threeway pump of this utility model, it includes syringe 1, three-way valve 3, feed liquor conduit 11, goes out fluid catheter 5, several joints etc.Syringe 1 can be a common syringe, is used for finishing the notes of taking out of liquid by pull core bar and piston.Three-way valve 3 connects syringe 1 respectively by joint 2,4,9 and goes out fluid catheter 5, feed liquor conduit 11, and the direction of the said turnover liquid of this utility model is when extracting body fluid out, the relative three-way valve of flow direction.This utility model three-way valve 3 is provided with and leads to knob, leads to knob by rotation, the conducting of control three-way valve, its essence is two two-way valves, the one, syringe 1 and go out fluid catheter 5 conductings is discharged body fluid from syringe 1, another is syringe 1 and 11 conductings of feed liquor conduit, extracts body fluid from focus out.In focus during dosing, therewith roughly the same.The concrete structure of three-way valve 3 belongs to prior art, is not describing in detail here.
Also be provided with liquid stopping clamp 10 on this utility model feed liquor conduit 11, be used for preventing the body fluid outflow.The reliability of operating when extracting body fluid or dosing out for assurance, the connector at feed liquor conduit 11 two ends is cone joints.Wherein feed liquor conduit 11 is connected by female cone joint 9 with syringe 1; Feed liquor conduit 11 connected with being connected by outer cone joint 13 of puncture needle or drainage tube.Outer cone joint 13 also is provided with helmet 14.Go out fluid catheter 5 other ends and also be provided with two pass joints 7, which is provided with helmet 8.
This utility model feed liquor conduit 11, go out also to be respectively equipped with on the fluid catheter 5 conduit mark card 12,6, be used for indicating the purposes of conduit.
This utility model adopts three-way valve 3 to connect syringe 1 and conduit, by three-way valve 3 control take out beam to, when drain is used, cone joint 13 connects puncture needle or drainage tube, joint 7 connects drain tube, by the piston of continuous pull, pushing syringe 1, can under the situation of not extracting drainage tube and syringe, extract drain body fluid continuously out.When injection is used, under the situation of not extracting drainage tube or puncture needle, add medicinal liquid by syringe.This utility model simple structure, easy to operate, high efficiency, safe in utilization.
