At this situation, Chinese patent 961077190 discloses a kind of automatic medical injection instrument of being made up of syringe and driving device thereof, it is by the single-chip microcomputer micro computer, the keyboard special of computer, display, alarm, solid-state relay and electric manipulator are formed, computer storage doctor's optimal injection parameter and radiography parameter, computer commander electric manipulator is finished the injection operation of optimal parameter, the computer expert crosses the solid-state relay X-ray machine exposure film making of commanding behind the scenes, the doctor deposits optimal parameter computer in and adjusts the control computer work at any time by it by keyboard special, and the computer expert crosses display, alarm is reported the working condition of instrument in time Xiang the doctor.Though this scheme solves the doctor to a certain extent and exempts from the irradiation that is subjected to X ray, its complex structure, with high costs, exploitativeness is relatively poor.
Summary of the invention
Technical problem to be solved by this invention is how a kind of automatic injecting instrument for brain angiography is provided, and this injection instrument can be finished contrast-medium injection and X-ray machine radiography overall process automatically, can make medical personnel exempt from the irradiation of X ray.
Technical problem proposed by the invention is to solve like this: construct a kind of automatic injecting instrument for brain angiography, it is characterized in that:
A, comprise half slot shape body, be provided with spring and spring pedestal at the rear portion of described body, the other end of spring is connected with the piston suitable with body, the front portion of body is provided with the syringe deck, this deck leaves the preformed hole that entry needle is passed through, and the distance between piston and the syringe deck can be placed a syringe;
B, also comprise that electromagnetism two position three-way valve and control circuit, described electromagnetism two position three-way valve are connected on the sebific duct between syringe and the puncture needle, by the conducting of control circuit control sebific duct; Described control circuit comprises parts such as electromagnetic relay, the time relay, A.C. contactor and rotary switch, wherein electromagnetic relay coil, the time relay and rotary switch are connected in series, time relay on-delay closing contact and ac contactor coil are connected in series, and the A.C. contactor moving together contact is connected in the control circuit of X-ray machine.
According to automatic injecting instrument for brain angiography provided by the present invention, it is characterized in that described piston is provided with pitch brace.
According to automatic injecting instrument for brain angiography provided by the present invention, it is characterized in that, also be provided with LED relay indicating light and safeguard in the described control circuit.
Beneficial effect of the present invention is: medical personnel can put into injector for medical purpose " the injection instrument body " of this instrument; and after connecting " electromagnetism two position three-way valve ", cerebral arteries puncture needle; can return in the X-ray machine OPS of protection; operate this instrument mechanical-electrical-hydraulic integration control system; (be generally 2～4 seconds) in the time in doctor's advice and finish automatically and to inject contrast agent--the work process of-x-ray imaging; both finish the cerebral angiography requirement, and protected medical personnel not injured by x-ray again effectively.
Description of drawings
Fig. 1 is the frame for movement sketch map of automatic injecting instrument for brain angiography provided by the present invention;
Fig. 2 is the electric control schematic diagram of automatic injecting instrument for brain angiography provided by the present invention.
Wherein, 1, pull bar, 2, piston, 3, injector for medical purpose, 4, spring pedestal, 5, spring, 6, body, 7, contrast agent, 8, two position three-way valve, 9, cerebral arteries puncture needle, 10, the electromagnetism AC coil, FU, protective tube, SA, rotary switch, YA, electromagnetism AC coil, KT, the time relay, KT1, on-delay closing contact, KM, contactor coil, KM1, radiography display lamp closing contact.
The specific embodiment
The present invention is described further below in conjunction with accompanying drawing.
As Fig. 1, shown in Figure 2, this automatic injecting instrument comprises half slot shape body 6, be provided with spring 5 and spring pedestal 4 at the rear portion of body 6, the other end of spring 5 is connected with the piston 2 suitable with body, piston 2 is provided with pull bar 1, the front portion of body 6 is provided with the syringe deck, this deck leaves the preformed groove that entry needle is passed through, distance between piston 2 and syringe deck can be placed syringe 3, also comprise two position three-way valve 8 and control circuit, two position three-way valve 8 is connected on the sebific duct between syringe 3 and the puncture needle 9, by the conducting of control circuit control sebific duct.Control circuit comprises parts such as electromagnetism relay coil YA, time relay KT, contactor coil KM and rotary switch SA, wherein electromagnetism relay coil YA, time relay KT and rotary switch SA are connected in series, and contactor coil KM and on-delay Closing Switch KT1 are connected in series.Also be provided with LED relay indicating light and safeguard FU in this control circuit.
The work process of this automatic injecting instrument is as follows: patient lies in X-ray machine irradiation area place in advance, and the cerebral arteries puncture needle has also penetrated patient's intracranial.Medical personnel are standby with an amount of liquid contrast agent suction injector for medical purpose, and injector for medical purpose and two position three-way valve connect by sebific duct; Draw " pull bar " compression spring, and with injector for medical purpose put into the injection instrument body after, put down pull bar gently, make piston withstand the handle that pushes away of syringe, because two position three-way valve is in not on-state, contrast agent can not enter patient's intracranial by the cerebral arteries puncture needle, and contrast agent pushes away at spring, piston, syringe under the compressing of handle, waits for the conducting order of two position three-way valve.Arrive this, preparation finishes.
