Description
Technical field
this utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of precharging type syringe.
Background technology
syringe is one of the most frequently used utensil of medical field, syringe is made up of the foraminate syringe of leading portion band and the piston core bar that matches, syringe is used for that a small amount of liquid or its are injected into region that other method cannot be approaching or from those local extractions out, when core bar is extracted, liquid or gas suck from syringe front end aperture, in the time that core bar pushes, liquid or gas are extruded.Be called injection by this process of syringe and syringe needle extraction or injecting gas or liquid.
in actual use, syringe generally all needs to coordinate draw point to use, and after syringe needle is arranged on the aperture of syringe leading portion, then syringe needle is inserted in various medicine bottles and extracts medicinal liquid to syringe, is then utilizing syringe to carry out follow-up medical care precess.But find in actual use, it is exactly a cumbersome thing that medical personnel use syringe from medicine bottle, to extract medicinal liquid itself, increased medical personnel's workload, and syringe needle is easy to produce and contact with pollutant in environment, thereby medicinal liquid or syringe are produced to pollution.
Summary of the invention
this utility model object is to provide a kind of precharging type syringe, uses this syringe, can avoid secondary pollution, and can alleviate medical and nursing work amount.
the technical solution of the utility model is: a kind of precharging type syringe, comprise overcoat, push rod and plug, described overcoat top is provided with the joint with pin hole, described joint is 6:100 female Luer, described push rod top is connected with described plug, described push rod and plug are arranged in described overcoat and overcoat slip relatively, also comprise helmet structure, described overcoat top is positioned at described joint outside and is provided with stationary magazine creel, and described helmet structure is arranged between described joint and stationary magazine creel and with described stationary magazine creel and is threaded.
further technical scheme, described helmet structure is made up of shell and the sealing shroud that is arranged in shell, formation boss stretches out in the middle part of described shell, described boss can be conflicted with described stationary magazine creel top end face, described stationary magazine creel inwall is provided with 6:100 luer lock joint, is engaged in and on described outer shell outer wall, is positioned at described boss below and is provided with external screw thread with described luer lock joint.
further technical scheme, the inner corresponding described pin hole of described sealing shroud position is provided with seal convexity, and the external diameter of described seal convexity matches with described pin hole internal diameter.
further technical scheme, described push rod top is threaded with described plug.
the utility model has the advantages that:
1. this utility model is by being positioned at joint arranged outside stationary magazine creel on overcoat top, helmet structure is set between joint and stationary magazine creel, and helmet structure is threaded with stationary magazine creel, in use, owing to being filled with in advance medicinal liquid in overcoat, only need take off helmet structure, can normally use syringe, use as compared with the past more conveniently, and be difficult for contacting with environment generation, secondary pollution can be avoided, and medical and nursing work amount can be alleviated;
2. this utility model is by sealing shroud the inner, seal convexity being set, and sealing projection external diameter coordinates with the internal diameter of pin hole, can effectively play the effect of sealing;
3. this utility model is simple in structure, easy to use, is applicable to promoting the use of.
Accompanying drawing explanation
below in conjunction with drawings and Examples, this utility model is further described:
fig. 1 is the structural representation of this utility model embodiment mono-.
wherein: 1, overcoat; 2, push rod; 3, plug; 4, joint; 5, stationary magazine creel; 6, shell; 7, sealing shroud; 8, boss; 9, seal convexity.
The specific embodiment
embodiment mono-: shown in Figure 1, a kind of precharging type syringe, comprise overcoat 1, push rod 2 and plug 3, described overcoat 1 top is provided with the joint 4 with pin hole, described joint is 6:100 female Luer, described push rod 2 tops are threaded with described plug 3, described push rod 2 and plug 3 are arranged in described overcoat 1 and overcoat slip relatively, also comprise helmet structure, described overcoat 1 top is positioned at described syringe needle 4 outsides and is provided with stationary magazine creel 5, and described helmet structure is arranged between described joint 4 and stationary magazine creel 5 and with described stationary magazine creel and is threaded.
described helmet structure is made up of shell 6 and the sealing shroud 7 that is arranged in shell 6, described shell 6 middle parts stretch out and form boss 8, described boss 8 can be conflicted with described stationary magazine creel 5 top end faces, described stationary magazine creel 5 inwalls are provided with 6:100 luer lock joint, are engaged in and on described shell 6 outer walls, are positioned at described boss 8 belows and are provided with external screw thread with described luer lock joint.
described sealing shroud 7 inner corresponding described pin hole positions are provided with seal convexity 9, and the external diameter of described seal convexity 9 matches with described pin hole internal diameter.
in the present embodiment, precharging type syringe is in the time of sealing state, the overcoat inside of hollow is filled with medicinal liquid in advance, helmet structure is connected and fixed between stationary magazine creel and joint via the external screw thread of shell and the 6:100 luer lock joint screw thread of stationary magazine creel inwall, now sealing shroud is arranged in the effect of playing sealing between shell and joint, the pin hole position of the inner corresponding syringe needle of sealing shroud is also provided with a seal convexity, the external diameter of sealing projection coordinates with the internal diameter of pin hole, can stick in pin hole, better play sealing effectiveness.In the time that precharging type syringe need to use, only need to screw off helmet structure, the joint of syringe is connected with conduit or other medical apparatus and instruments of injecting medical liquid to be added, can normally use.
certainly above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All modifications of doing according to the spirit of this utility model main technical schemes, within all should being encompassed in protection domain of the present utility model.
