Abstract
The utility model discloses a composite syringe capable of being pressurized in a rotating mode or pushed through a piston. The composite syringe comprises a hollow columnar body, wherein one end of the body is provided with a catheter connector which is sleeved with a nipple, and a composite push injection rod is inserted in the other end of the body. Through the composite push injection rod composed of an independent rod body and a push injection rod body, push injection of the syringe can be freely selected to be the rotatable pressurizing mode or the piston push injection mode according to the actual requirements of patients, so that push injection quantity can be accurately regulated and controlled, and the problem that the push injection quantity of an existing common syringe can not be accurately regulated and controlled is solved.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to the composite injection device that a kind of rotatable pressurization or piston push.
Background technology
At present, in the clinical row artery embolization for treatment of intervention radiation doctor process, especially iodized oil is by the process of microtubular thromboembolism target vessel, often need very accurately to control iodized oil and inject speed and bolus amount, ordinary syringe is due to himself architectural characteristic, make it have the defect of following several respects: 1, iodized oil is injected speed and bolus amount is uncontrollable, cannot regulate and control flexibly according to different patients' situation, often there is the too large or too little situation of moment bolus amount, disturb embolotherapy process; 2, need to inject the patient of heavy dose of iodized oil for some, in the time of application microtubular thromboembolism, require great effort time-consuming, extend the thromboembolism time, increase the roentgen radiation x time, all bring unnecessary damage to patient and doctor.
Utility model content
The purpose of this utility model is to provide the composite injection device of a kind of rotatable pressurization or piston propelling movement, regulates and controls coarse problem to solve existing ordinary syringe bolus amount.
The technical scheme that this utility model adopts is, the composite injection device that a kind of rotatable pressurization or piston push comprises the body of open column shape, and one end of body is provided with catheter adapter, and catheter adapter overcoat has nipple, and the other end of body is inserted with the compound bar of injecting; The described compound bar of injecting that bar comprises hollow of injecting, injecting one end of bar stretches in the cavity of body, inject in bar and run through and be provided with independent bar along its axis direction, independent bar with the inwall of injecting bar for being threaded, independent bar is connected with valve near one end of nipple, and independent bar is provided with holder handle away from one end of nipple; The described bar of injecting is provided with reverse aerocurve plate a near one end of holder handle, and described body is provided with reverse aerocurve plate b near one end correspondence of reverse aerocurve plate a.
The inwall of injecting bar and body further, is interference fit.
Further, described nipple is that screw fastening type is connected with catheter adapter.
Further, the material of described body is transparent rigid plastics.
The beneficial effects of the utility model are, by by independent bar with inject the compound bar of injecting that bar forms, make the syringe in use can be according to patient's actual needs, freely select the mode of injecting of rotation pressurization or the mode that piston type is injected, thereby realize the accuracy controlling to bolus amount, solved existing ordinary syringe bolus amount and regulated and controled coarse problem.
Brief description of the drawings
Fig. 1 is the structural representation of the composite injection device of a kind of rotatable pressurization of this utility model or piston propelling movement.
In figure, 1. body, 2. independent bar, 3. valve, 4. injects bar, 5. nipple, 6. holder handle, 7. reverse aerocurve plate a, 8. reverse aerocurve plate b.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is elaborated.
The composite injection device that this utility model provides a kind of rotatable pressurization or piston to push, its structure, referring to Fig. 1, comprises the body 1 of open column shape, and one end of body 1 is provided with catheter adapter, catheter adapter overcoat has nipple 5, and the other end of body 1 is inserted with the compound bar of injecting.Wherein, compound inject that bar comprises hollow inject bar 4, injecting one end of bar 4 stretches in the cavity of body 1, inject that bar 4 is interior to be run through and be provided with independent bar 2 along its axis direction, independent bar 2 with the inwall of injecting bar 4 for being threaded, independent bar 2 is connected with valve 3 near one end of nipple 5, and independent bar 2 is provided with holder handle 6 away from one end of nipple 5; Injecting bar 4 is interference fit with the inwall of body 1; Inject bar 4 and be provided with reverse aerocurve plate a7 near one end of holder handle 6, body 1 is provided with reverse aerocurve plate b8 near one end correspondence of reverse aerocurve plate a7; Nipple 5 is that screw fastening type is connected with catheter adapter; The material of body 1 is transparent rigid plastics.
The composite injection device that a kind of rotatable pressurization of the present utility model or piston push, its front-end architecture is set to screw fastening type nipple 5, can firmly be fixedly connected with the catheter adapter of body 1, prevents slippage; Compound push rod comprise the independent bar 2 of rotatable pressurization and can piston type inject inject bar 4, make it in the time being applied to microtubular iodized oil, can be in rotating bolus injection or piston type be injected, select the suitable mode of injecting according to patient's actual needs, thereby accurately control moment bolus amount, avoided conventional syringe cannot accurately control the shortcoming of bolus amount; Meanwhile, rotation pressurization is injected design and is made that thromboembolism is laborsaving to save time, and reduces the thromboembolism time, has reduced the roentgen radiation x time, is very easy to interventional embolization operation, result of use highly significant; In addition, the reverse aerocurve plate a7 being oppositely arranged and oppositely aerocurve plate b8, make to control in bolus infusion processes syringe more reliable.
The material of body 1 is transparent rigid plastics, in use, control effective, can not cause device deformation because of operation, the cavity of body 1 can be designed to the volume of different sizes, for example 2-5mL, injects bar 4 and can be designed to different length, for example 2-3cm according to practical situation, the material thickness of injecting bar 4 is 1.9-2.1mm, to adapt to different sick human needs.
