Abstract
The utility model provides an automatic propelling device for a syringe, comprising a cylinder, wherein, the left end of the cylinder is provided with an air releasing valve, an air nozzle and a regulating valve which are respectively communicated an inner cavity of the cylinder, a piston glidingly matched with the cylinder is arranged in the cylinder, the right part position of the cylinder is provided with an air escaping hole communicated with the inner cavity of the cylinder, and the right end of the cylinder is provided with an end sleeve which is in threaded match with the right end. The utility model can perform the operation of injecting contrast medium to patients without requiring medical staff to enter CT chambers. The utility model is a technique which is worth generalizing.
Description
This utility model relates to technical field of medical instruments, the automatic propeller of specifically a kind of syringe.
At present, when the medical personnel patient that reinforcement scans to needs carries out injection of contrast medium work, then will enter in the comparatively serious CT Room of radioactive pollution, directly the patient be injected, be sizable to the healthy influence of medical personnel like this.
The purpose of this utility model is for solving above-mentioned insufficient section, provide a kind of medical personnel of need not to enter CT Room, can carrying out the automatic propeller of syringe of injection of contrast medium work to the patient.
The purpose of this utility model is achieved through the following technical solutions: the automatic propeller of syringe, it has cylinder barrel, the left end of cylinder barrel has atmospheric valve, valve and the control valve that communicates with its inner chamber respectively, the piston that is slidingly fitted with it is arranged in cylinder barrel, on the right part position of cylinder barrel the bleeder port that communicates with its inner chamber is arranged, have on the right-hand member of cylinder barrel and its end cover of threaded engagement mutually.
Advantage of the present utility model: one, reasonable in design, it is by the air of input certain pressure in cylinder barrel, make the piston motion in the cylinder barrel, automatically advance syringe that the patient is injected thus, so thoroughly avoided medical personnel to enter CT Room directly carries out injection of contrast medium work to the patient drawback; Two, simple in structure, easy making, with low cost, easy to use and reliable.Extensive use of the present utility model can produce good social, economic benefit.
Figure of description is a structural representation of the present utility model.
In conjunction with the embodiments this utility model is described in further detail below with reference to Figure of description.
The automatic propeller of syringe of the present utility model, it has cylinder barrel 4, the left end of cylinder barrel 4 has atmospheric valve 2, valve 14 and the control valve 10 that communicates with its inner chamber respectively, the piston 5 that is slidingly fitted with it is arranged in cylinder barrel 4, the bleeder port 6 that communicates with its inner chamber is arranged on the right part position of cylinder barrel 4, have on the right-hand member of cylinder barrel 4 and its end cover 8 of threaded engagement mutually.Spool 3 is arranged in the control valve 10, and the valve gap 13 that has a pore 12 and control valve 10 be threaded engagement mutually, the stage clip 11 in the control valve 10, and its two ends contact with spool 3 and valve gap 13 respectively.
During making, process various parts assemblings by above-mentioned requirements and get final product.During use, this utility model is fixed on the support, by flexible pipe valve 14 and air pressure container outlet are joined, outward winding behind the plug 1 on the atmospheric valve 2, the piston 5 in the cylinder barrel 4 is passed the left end of cylinder barrel 4 with a thin rod, outward winding the then end cover 8 of cylinder barrel 4 right-hand members, the syringe that contrast agent is housed is inserted in the cylinder barrel 4, and the pintle 7 of syringe is contacted with piston 5, to hold cover 8 to be inserted in the needle tubing 9 of syringe again, and screw end cover 8, its left end is contacted with needle tubing 9 afterbody boss get final product.At this moment, the tube for transfusion of need being strengthened the prior transfusion of scan patients unplugs, and it is inserted in needle tubing 9 exits that contrast agent is housed gets final product, at this moment medical personnel can be outside CT Room console switch, gas in the air pressure container is entered in the cylinder barrel 4, promote piston 5 end motion to the right, advance 7 couples of patients of pintle to inject thus.When pintle 7 was pulled to the right-hand member of needle tubing 9, the left end of piston 5 was corresponding with the bleeder port 6 on the cylinder barrel 4, no pressure in this moment cylinder barrel 4, and 5 stop motions of piston protect syringe not to be damaged with this.Air pressure container and the support that uses that match with this utility model is prior art, just do not give unnecessary details one by one here.
