Abstract
The utility model relates to a medical three-way drawing and injection device, which comprises a syringe, a three-way joint, catheters, one-way valves and a joint, wherein the three-way uses the catheters to respectively connect the syringe and the inlet and outlet one-way valves; between the inlet one-way valve and the joint on the inlet conduit also a medicine-adding three-way joint is provided. The utility model controls drawing and injection flow direction through a one-way valve and can be connected for many times to draw out the liquid or inject the medicine lotion without the need of pulling out the drainage tube and the syringe. The structure is simple, operation and use is convenient, working efficiency is high, cost is low and the safe performance is high.
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, threeway, conduit, check valve, joint, threeway connects syringe and two liquid inlet and outlet check valves respectively by conduit, it is characterized in that: also be provided with the dosing threeway on the feed liquor conduit between feed liquor check valve and the joint.
This utility model is owing to adopt threeway to connect syringe and two check valves, the feed liquor conduit is provided with the dosing threeway, by check valve control take out beam to, can be under the situation of not extracting drainage tube and syringe, add the treatment medicinal liquid, 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. conduit, 3. threeway, 4. fluid check valve, 5. feed liquor check valve, 6. feed liquor conduit, 7. dosing threeway, 8. liquid stopping clamp, 9. cone joint.
The specific embodiment
As can be seen from Figure 1, a kind of medical threeway pump of this utility model, it includes syringe 1, threeway 3, conduit 2, check valve 4,5, joint 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.Threeway 3 is by conduit and connect syringe 1 and two feed liquor check valves 5, fluid check valve 4 respectively, and the direction of this utility model turnover liquid is relative threeway.The control flow direction that is fluid check valve 4 is threeway dorsad, and correspondingly connecting duct can only be by the injection trickle; It is to enter threeway that the control of feed liquor check valve 5 flows to, and correspondingly feed liquor conduit 6 can only pass through pull piston inspiration liquid.This utility model feed liquor conduit also is connected with cone joint 9, and cone joint 9 outer ends also are provided with protective sleeve.
Characteristics of the present utility model are: also be provided with dosing threeway 7 between feed liquor check valve 5 and the joint 9 on the feed liquor conduit 6, add medicine to focus when being used for treating.When preventing dosing, the liquid outflow also correspondingly is provided with liquid stopping clamp 8 on the feed liquor conduit 6 between feed liquor check valve and dosing threeway.
This utility model adopts threeway 3 to connect syringe 1 and two check valves, by check valve 4,5 controls take out beam to, and on feed liquor conduit 6, be provided with dosing threeway 7.When drain was used, cone joint 9 connect puncture needle or drainage tube, and joint connects drain tube, by the piston of continuous pull, pushing syringe 1, can extract drain body fluid continuously out under the situation of not extracting drainage tube and syringe.When injection is used, clamp liquid stopping clamp 8, under the situation of not extracting drainage tube or puncture needle, add medicinal liquid by dosing threeway 7.This utility model simple structure, easy to operate, high efficiency, safe in utilization.
