Abstract
The utility model provides a three-way injection-extraction machine. The three-way injection-extraction machine comprises a three-way infusion tube, wherein the three-way infusion tube comprises a suction tube, a drainage tube and an output tube, wherein the suction tube is connected with a needle head; the drainage tube is connected with an injector; the output tube is connected with a liquid storage bag; the suction tube and the output tube are respectively provided with a first valve and a second valve; a medicine injection cap is additionally arranged on the suction tube; and the medicine injection cap is arranged between the needle head and the first valve. A doctor uses the three-way injection-extraction machine for injecting liquid medicine to the body of a patient through the medicine injection cap and then extracting body fluid after the injection without pulling out the needle head, so that the painful feeling of the patient is relieved, and operation processes are also simplified.
Description
Technical field
This utility model relates to a kind of pump, particularly relates to a kind of threeway pump.
Background technology
The threeway pump is very important medical apparatus and instruments in carrying out breast, abdominal paracentesis operation process, and the doctor uses the threeway pump that the body fluid such as the hydrops in the patient body, congestion are extracted out, again these body fluid is injected liquid storing bag.Although the threeway pump has made things convenient for doctor's extracting bodily fluid, in the therapeutic process of reality, often be in extracting bodily fluid, also need in patient body, inject liquid medicine at identical position.When running into this situation, the method for employing generally has two kinds at present, and the one, the syringe needle of threeway pump is extracted, use new syringe and needle injection liquid medicine, after the liquid medicine injection is complete, reinsert again the syringe needle of threeway pump, continue extracting bodily fluid; Another is the syringe needle of not extracting the threeway pump, and new syringe needle is inserted in position aside.These two kinds of methods all must increase patient's pain, also make the operating process of operation loaded down with trivial details, and difficulty strengthens.
The utility model content
Technical problem to be solved in the utility model provides a kind of threeway pump, and the doctor uses this threeway pump to be patient infusion liquid medicine when extracting patient's body fluid, has simplified the operation sequence for the treatment of, has alleviated patient's misery.
The technical scheme that this utility model technical solution problem adopts is: this threeway pump comprises the threeway tube for transfusion, described threeway tube for transfusion comprises suction tube, drainage tube and outlet tube, described suction tube is connected with syringe needle, described drainage tube is connected with syringe, described outlet tube is connected with liquid storing bag, be respectively arranged with the first valve and the second valve at described suction tube and outlet tube, also be provided with the injection medicated cap on described suction tube, described injection medicated cap is arranged between described syringe needle and described the first valve.After closing the first valve, in patient body, inject liquid medicine by the injection medicated cap, needn't extract syringe needle, continue extracting bodily fluid after the injection, alleviated patient's pain, also simplified operation sequence.
For shortening the mobile distance of liquid medicine, described injection medicated cap is arranged at the position near described syringe needle.
Described the first valve and the second valve are flow regulator, and flow regulator can accurately be controlled the speed of extracting bodily fluid and body fluid is injected the speed of liquid storing bag, is convenient to the character that the doctor observes body fluid.
The beneficial effects of the utility model are: the doctor neither needs to extract syringe needle when using this threeway pump to carry out breast, abdominal paracentesis operation, also do not need to use other syringe just can inject liquid medicine in patient body.Avoided repeatedly plugging the misery that syringe needle brings to the patient, more timely to patient's treatment.Simultaneously, this threeway pump can accurately be controlled the speed of extracting bodily fluid, thereby avoids also being conducive to the doctor and observing the body fluid character because extraction speed increases the patient suffering too soon, prevents from patient's fresh blood is released.
Description of drawings
Fig. 1 is the structural representation of this utility model threeway pump.
The specific embodiment
As shown in Figure 1, in the process of extracting bodily fluid, open the first valve 7, close the second valve 8, pulling syringe 2, body fluid flow enters syringe 2 through suction tube 4 and drainage tube 5; Then close the first valve 7, open the second valve 8, pushing syringe 2, body fluid flow enters liquid storing bag 3 through drainage tube 5 and outlet tube 6.So be provided with injection medicated cap 9 at suction tube 4, injection medicated cap 9 is arranged between syringe needle 1 and the first valve 7.When needs injection liquid medicine, close the first valve 7, liquid medicine is injected in the suction tube 4 by injection medicated cap 9, liquid medicine is expelled in the patient body by suction tube 4 and syringe needle 1.Because have inevitably certain distance between the middle joint portion of the second valve 8 and threeway tube for transfusion, so, if with on 9 settings of injection medicated cap and the drainage tube 5, even close the second valve 8, also have part liquid medicine and flow into outlet tube 6, cause waste.Adopt set-up mode as shown in Figure 1, can prevent that liquid medicine from refluxing, and avoids waste.Use this threeway pump, the doctor is when giving patient infusion liquid medicine, just do not need to extract syringe needle 1, re-use new syringe and syringe needle, perhaps use simultaneously other syringe and syringe needle, avoid repeatedly plugging the misery that syringe needle 1 brings to the patient, also simplified operative procedure, reduced operation easier.
In order to shorten the mobile distance of liquid medicine in suction tube 4, injection medicated cap 9 is arranged at the position near syringe needle 1.In the journey that extracts patient's body fluid, the tube wall inboard of suction tube 4 must be attached with body fluid, injection medicated cap 9 is arranged at the position of close syringe needle 1, can reduce body fluid to the pollution of liquid medicine, simultaneously, liquid medicine flows apart from short, more be conducive to control the injection rate of liquid medicine, cut the waste.
A kind of better mode is that the first valve 7 and the second valve 8 all adopt flow regulator.The first valve 7 use traffic actuators can make the doctor accurately control the speed of extracting bodily fluid, be convenient to observe the body fluid in the suction tube 4, prevent from patient's fresh blood is extracted out, also avoided extracting excessive velocities and the various complication that cause and the pain that strengthens the patient.The second valve 8 use traffic actuators can the control volume liquid stream enter the speed of liquid storing bag 4, are convenient to the doctor and observe fluid conditions, such as color, viscosity etc., thereby in time judge conditions of patients.
