Abstract
The utility model relates to a medical three-way pumping and injecting device, which comprises an injector, a three-way, a conductor, two one-way valves, and cone connectors. The three-way is connected with the injector and the two cone connectors, and the two one-way valves are arranged between the cone connectors and the three-way. And the two one-way valves respectively control the back flows and the entry into the three-way. The utility model controls the pumping and injecting flows through the one-way valves, and continuously pumps body fluid or injects soup in multi-time under the circumstances of no extracting a drain and the injector. The utility model has simple structure, convenient operation and employment, high efficiency, low cost, and excellent safe performance.
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.At present, but also do not have special-purpose continuous uninterrupted to extract the medical threeway pump that body fluid maybe can inject medicinal liquid out on the market.
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 is characterized in that: 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 two cone joints and the threeway, the control of two check valves flows to be respectively dorsad and to enter threeway.
This utility model is owing to adopt threeway to connect syringe and two cone joints that are provided with check valve, by check valve 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 need not used power supply, high efficiency, cost is low, and security performance is good.
Description of drawings
Below in conjunction with drawings and Examples 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. check valve, 5. check valve, 6. cone joint, 7. 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, conduit 2, threeway 3, check valve 4,5, cone joint 6,7.Syringe 1 is exactly a common syringe, is used for finishing the notes of taking out of liquid by pull core bar and piston.Threeway 3 connects syringe 1 and two cone joints 6,7 by conduit 2.Be respectively equipped with check valve 4,5 between two cone joints 6,7 and the threeway 3.On the conduit that check valve 4,5 can be connected between them, promptly there is conduit to be connected between cone joint and the check valve; Also can directly link to each other with cone joint 6,7.The control of two check valves 4,5 flows to be respectively dorsad and to enter threeway, i.e. it is threeway dorsad that the control of check valve 4 flows to, and correspondingly cone joint 6 can only be by the injection trickle.It is to enter threeway that the control of check valve 5 flows to, and correspondingly cone joint 7 can only pass through pull piston inspiration liquid.This utility model cone joint 6,7 outer ends also are provided with helmet.
This utility model adopts threeway 3 to connect syringes 1 and two check valves and cone joint, by check valve 4,5 controls take out beam to.When drain was used, cone joint 7 connect puncture needle or drainage tube, and cone joint 6 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 was used, cone joint 6 connect puncture needle or drainage tube, and cone joint 7 connects the medicinal liquid bottle, by the piston of continuous pull, pushing syringe 1, can inject medicinal liquid continuously under the situation of not extracting drainage tube or puncture needle.This utility model simple structure, easy to operate, high efficiency, safe in utilization.
Claims (4)
1. medical threeway pump, it is characterized in that: 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.
2. medical threeway pump according to claim 1 is characterized in that: be connected with conduit between cone joint and the check valve.
