In embolotherapy process, injection pressure is a very crucial important parameter, often determines the success or failure for the treatment of.When injection of sclerosing agent, if injection pressure is excessive, injection of sclerosing agent is many and dark, and postoperative easy generation organ cicatricial stricture, affects its normal physiological function; And if injection pressure is too small, in blood vessel, sclerosing agent is inadequate, easily increases again the risk of intraoperative hemorrhage.Therefore person's moment is paid close attention to, to need operation technique.But adopt ordinary syringe more than the embolotherapy of current human peripheral blood pipe clinically, injection pressure size is often held by operator's sensation on hand, the control of neither one objective criterion, this method by experience or maneuver, has increased the risk of operation and operator's difficulty undoubtedly.
In prior art, also have the injection device that can show or indicate injection pressure.As patent documentation CN202490265U discloses a kind of pressure indicator type syringe, in injecting handle, syringe is provided with the pressure indicator being formed by elastic element, inject handle and be provided with scale, carry out directly accurately indication intravascular pressure by this pressure indicator arranging between syringe and puncture needle.Patent documentation CN102266601B discloses a kind of syringe and pressure detection mechanism of injector pump, in this application, pressure transducer is set directly on the outer wall of injection pipeline, thereby make its can direct-detection the pressure of injection pipeline change.
But, in above-mentioned prior art, syringe all can only be realized the object of direct indication or detection injection pressure, send pressure caution or realize direct pressure release or the direct excessive problem of pressure relief and can not reach, even injection pressure has shown in the time of operation, but still existence is excessive because careless manipulation causes suppository or hardware agent to be injected, make embolotherapy operation still exist certain risk
?.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that existing pressure shows injection device, provide a kind of can either Measurement accuracy pressure in injection process, again can be at the excessive alarm of pressure and drainage decompression automatically, the syringe of pressure relief problems of too.
For achieving the above object, detailed technology scheme of the present utility model is: a kind of syringe, comprise injection mechanism, connecting hose and injection needle, injection mechanism by a syringe, be arranged on the piston in syringe, and the push rod that connects piston forms, push rod stretches out one end of syringe, the other end socket connecting hose of syringe, in connecting hose, connect the Pressure gauge of a signal of telecommunication control type by tee T, connect a ball-type overflow valve by tee T again, the far-end of connecting hose connects injection needle by extension tube.
Syringe of the present utility model, in the connecting hose between injection mechanism and syringe needle, be connected with Pressure gauge and the ball-type overflow valve of signal of telecommunication control type, in the time being expert at suppository or injection of sclerosing agent, not only can directly show the injection pressure in connecting hose in injection process, and can in Pressure gauge, preset a dangerous values, in the time that injection pressure reaches dangerous values, pressure ball-type overflow valve is opened automatically, by the overflowing mouth discharge opeing decompression of overflow valve.The problem that thereby the injection that reaches sclerosing agent while avoiding thromboembolism sclerotherapy is excessive, injection pressure is excessive, avoids operation risk greatly, makes to perform the operation safer, has higher success rate.
Further, in order to reach the object of carrying out in advance safety instruction or dangerous warning, on Pressure gauge, indicating device can also be set, respectively the safe pressure scope on corresponding indicated pressure scale and warning pressure limit.Indicating device can be the various means that are used to refer to or warn in prior art field, for example, can be display lamp, can be also sound etc.In the thromboembolism of being expert at when injection,, when injection pressure is during in safety range, indicating device gives safe indication.When sclerosing agent pushes the amount and the degree of depth that reach certain, injection pressure constantly raises, and in the time that injection pressure is elevated to fence coverage, indicating device sends warning indication to operator.This warning in advance can further avoid injection pressure to continue to be elevated to dangerous values again, thereby avoids Pressure gauge to trigger overflow valve, can more save surgical material, further reduces operation risk.
