Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of novel syringe.
Background technology
At present, the employed syringe push rod that mainly contains syringe needle, syringe and have a piston constitutes clinically, and this syringe simple in structure exerted pressure to push rod with hands by medical personnel, and the liquid in the syringe is gone in the human body by needle injection.The hand-pushing handle that the rear end of the push rod of syringe arranges is planar rondure, needs the back pulling-pushing rod to do when extracting action sometimes, and the hand-pushing handle on plane can't easily be finished, and medical personnel can only the map function posture, and this makes troubles to medical personnel.Traditional syringe generally is by syringe needle and syringe is split type constitutes, the front end face of syringe is provided with the syringe needle Connection Block, on the syringe needle socket syringe needle Connection Block, but such syringe needle is firm inadequately with being connected of syringe, in the process of inhaling medicine or injection, excessive or medical personnel shake reasons such as syringe owing to the syringe internal pressure, sometimes the phenomenon that syringe needle comes off can appear, this makes troubles to operation of medical workers, and waste medicinal liquid, if in injection process, even also malpractice can take place.In addition, syringe is after finishing to patient injection, and its structure, function are still intact, are easy to be recycled again, bring infected potential safety hazard to sufferer, serious threat patient's health.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provides that a kind of simple in structure, syringe needle and syringe are connected firmly, easy to use and safe novel syringe.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel syringe, the push rod that it comprises syringe, be slidingly mounted on the piston of syringe inside, be connected with piston and the syringe needle that is installed in the syringe end, the front end of described syringe is provided with and has externally threaded syringe needle mount pad, syringe needle mount pad and syringe are one-body molded, the afterbody of described syringe needle is provided with the Connection Block that has female thread, Connection Block and syringe needle are one-body molded, and the syringe needle mount pad is connected by threaded engagement with Connection Block; The afterbody of push rod is provided with the hand-pushing handle of annular.
The arranged outside of described syringe opening part has the grip part, and a side of grip part is arcs of recesses.
Described syringe needle outer cover is equipped with the pin cover, and the bossing of pin cover inside and the outer wall of Connection Block are connected.
Also be provided with the broken part on the described push rod.
The utlity model has following advantage:
1, the described syringe of this utility model is simple in structure.
2, syringe needle adopts threaded engagement to be connected with syringe, is connected firmly, and in medical personnel's use, the situation that syringe needle drops can not occur.
3, a side of grip part is set to arcs of recesses, cooperate with finger, and hand-pushing handle is annular, is convenient to push-and-pull that medical personnel are very easy to use, simple.
4, push rod is provided with the broken part, and after injection finished, medical personnel can fracture push rod very like a cork, prevents that syringe is recovered secondary and uses.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structure for amplifying sketch map at A place among Fig. 1;
Among the figure: 1-syringe, 2-syringe needle, 3-push rod, 4-syringe needle mount pad, 5-piston, 6-broken part, 7-Connection Block, 8-hand-pushing handle, 9-grip part, 10-pin cover.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As depicted in figs. 1 and 2, a kind of novel syringe, the push rod 3 that it comprises syringe 1, be slidingly mounted on the piston 5 of syringe 1 inside, be connected with piston 5 and the syringe needle 2 that is installed in syringe 1 end, the front end of described syringe 1 is provided with and has externally threaded syringe needle mount pad 4, syringe needle mount pad 4 is one-body molded with syringe 1, the afterbody of described syringe needle 2 is provided with the Connection Block 7 that has female thread, and Connection Block 7 is one-body molded with syringe needle 2, and syringe needle mount pad 4 and Connection Block 7 are connected by threaded engagement; The afterbody of push rod 3 is provided with the hand-pushing handle 8 of annular; The arranged outside of syringe 1 opening part has grip part 9, and a side of grip part 9 is concave arc; Syringe needle 2 outer cover are equipped with pin cover 10, and the bossing of pin cover 10 inside and the outer wall of Connection Block 7 are connected; Also be provided with broken part 6 on the push rod 3.
Work process of the present utility model is as follows: take the packaging bag of syringe apart, the Connection Block 7 of syringe needle 2 is aimed at syringe needle mount pad 4, connect by threaded engagement, syringe needle 2 and syringe 1 are coupled together, such connected mode socket mode more in the past is more firm.Adopt the hand-pushing handle 8 of annular and a side of grip part 9 to be set to arcs of recesses, these improve all is that medical personnel inhale medicine or action of injection for convenience.After injection finished, medical personnel fractureed push rod 3.
