Health threatens, and when carrying out cerebral angiography injection contrast agent, the injection of micro air can cause brain air tap
Plug, constitutes a threat to patient vitals.To avoid the air exhaustjet device of suction, medical personnel often take time to handle syringe
Interior air, undoubtedly add many workloads.
The content of the invention
To solve in the prior art, the existing operation of contrast medium injector is inconvenient, is easily caused the technology of brain air embolism
Problem, technical scheme are as follows：
Contrast agents of cerebral vessel syringe in the present invention, including push rod and syringe, the handheld terminal of the push rod, which is provided with, to be pushed away
Disk, the push rod porch of the syringe are provided with acupressure probe, and the push-plate or acupressure probe are rotatably connected to limiting plate, make limiting plate
Rotated around with the junction of push-plate or acupressure probe.
In a preferred embodiment, the push-plate is rotatably connected to limiting plate；The push-plate opens up mounting groove, institute
State one end of limiting plate and the side wall of mounting groove is connected by rotating shaft.
In a preferred embodiment, the acupressure probe is rotatably connected to limiting plate；The acupressure probe opens up installation
Groove, one end of the limiting plate and the side wall of mounting groove are connected by rotating shaft.
In a preferred embodiment, the push-plate opens up two mounting grooves, is rotatablely connected in the mounting groove
Limited location plate.
In a preferred embodiment, the acupressure probe opens up two mounting grooves, the equal company of rotation in the mounting groove
It is connected to limiting plate.
In a preferred embodiment, the mounting groove extends the edge of push-plate.
In a preferred embodiment, the mounting groove extends the edge of acupressure probe.
In a preferred embodiment, the distance of the dispensing end of the zero graduation line of the syringe and syringe is equal to described
The height of limiting plate.
Contrast agents of cerebral vessel syringe in the present invention, compared with prior art, its advantage is：
Contrast agents of cerebral vessel syringe in the present invention, it is simple in construction, easy to use, it can effectively prevent from injecting radiography
Brain air embolism is formed during agent, when a small amount of air suction be present, due to the setting of limiting plate, even if doctor
Shield personnel direct injection will not also cause air embolism, and therefore, medical worker need not take time to discharge on a small amount of air, and then
Medical worker's workload is reduced, improves operating efficiency.

Embodiment
Below in conjunction with the accompanying drawing of the present invention, technical scheme is clearly and completely described.Based on this hair
Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
As shown in figure 1, the invention provides contrast agents of cerebral vessel syringe, the push rod 1 and pin to be matched each other using length
Cylinder 3, the handheld terminal of push rod 1 is provided with push-plate 2, and the porch of push rod 1 of syringe 3 is provided with acupressure probe 4, and push-plate 2 is rotatably connected to
Limiting plate 5, surround limiting plate 5 and rotated with the junction of push-plate 2.In use, keep limiting plate 5 parallel with push-plate 2 first, root
The radiography dosage for needing to inject according to patient sucks liquid, the rotary stopper plate 5 after the completion of liquid is sucked, makes limiting plate 5 and push-plate 2
Vertically, position-limiting action then is formed because limiting plate 5 is vertically set between push-plate 2 and acupressure probe 4 to patient's neck injection,
Avoiding push rod 1 from being pushed into too deep causes air that may be present in syringe 3 to enter patient vessel.
As shown in Fig. 2 acupressure probe 4 is rotatably connected to limiting plate 5, surrounds limiting plate 5 and revolved with the junction of acupressure probe 4
Turn.In use, keeping limiting plate 5 parallel with acupressure probe 4 first, liquid is sucked according to the radiography dosage that patient needs to inject, when
Rotary stopper plate 5 after the completion of suction liquid, makes limiting plate 5 vertical with acupressure probe 4, then to patient's neck injection, due to spacing
Plate 5 is vertically set between push-plate 2 and acupressure probe 4 and forms position-limiting action, and avoiding push rod 1 from being pushed into, too deep cause in syringe 3 may
Existing air enters patient vessel.
As shown in figure 3, push-plate 2 opens up mounting groove 6, one end of limiting plate 5 is connected with the side wall of mounting groove 6 by rotating shaft 7,
Rotating shaft 7 is using prior art and has stopping means, and the maximum anglec of rotation for making limiting plate 5 and horizontal direction is 90 degree；For just
In medical personnel's rotary stopper plate 5, mounting groove 6 extends the edge of push-plate 2.As shown in figure 4, in one embodiment,
Push rod 1 shifts during to prevent from using, and causes the activity of limiting plate 5, two mounting grooves 6 are symmetrically opened up with the center of circle of push-plate 2, pacify
Limiting plate 5 is rotatably connected in tankage 6.
As shown in figure 5, acupressure probe 4 opens up mounting groove 6, one end of limiting plate 5 is connected with the side wall of mounting groove 6 by rotating shaft 7
Connect；Rotating shaft 7 is using prior art and has stopping means, and the maximum anglec of rotation for making limiting plate 5 and horizontal direction is 90 degree.Such as
Shown in Fig. 6, in one embodiment, push rod 1 shifts during to prevent from using, and causes the activity of limiting plate 5, with acupressure probe 4
Center line symmetrically open up two mounting grooves 6, be rotatably connected to limiting plate 5 in the mounting groove 6.As shown in fig. 7, another
In kind embodiment, for ease of medical personnel's rotary stopper plate 5, mounting groove 6 extends the edge of acupressure probe 4.
The distance of the zero graduation line of syringe 3 and the dispensing end of syringe 3 is equal to the height of limiting plate 5, in order to medical personnel
It is accurate to grasp injection volume.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
