Abstract
The utility model relates to a longitudinal opening and closing type injector, which is provided with a disposable boat-tailed needle head and a disposable piston-shaped injection tube. The utility model belongs to the technical field of clinical medicine and solves the disadvantages of high cost, complex operation and a plurality of contamination opportunities of the existing injectors. The utility model is characterized in that two casings of a tile-shaped injector are connected together by means of two coaxial shafts and are in a longitudinal opening and closing type. The utility model forms a cylinder after the utility model is closed. One end of the disposable injection tube is closed by a conical top and a threaded bottom. The disposable injection needle head forms a boat-tailed type with an elliptical handle. When the disposable injection tube and the disposable needle head are loaded in the closed injector casing, the utility model can be used for injecting directly and pumping back.
Description
This utility model belongs to clinical medicine domain.The syringe that uses clinically mainly contains two kinds now: a kind of is plastic injector for temporary use, and another kind is the reusable syringe that glass is made.Above-mentioned two kinds of syringes all will be extracted injection out from medicine bottle, inject again.So not only time-consuming, effort, and increased the liquid medicine contamination chance.It is more convenient that plastic injector for temporary use uses, but cost height, waste material are many.
This utility model purpose is to eliminate the weak point of existing syringe, provides a kind of metal longitudinal of being furnished with disposable two sharp formula syringe needles and disposable piston type liquid injection pipe to the open-close type syringe, its directly injection, but also pumpback.
This utility model purpose reaches by the following technical programs:
Syringe shell is vertical open-close type tubular structure, does not wait a watt shape shell to constitute by two, and connects together by two concentric shafts.In the syringe shell after disposable two sharp formula syringe needles and disposable liquid injection pipe are packed closure into, push-tight syringe top plug thrusts in the disposable liquid injection pipe disposable aspiration needle.Rotate injector push-rod, i.e. injectable and pumpback.
Description of drawings is as follows:
Pack into the longitudinal sectional drawing of the syringe shell after the closure of Fig. 1, disposable two sharp formula syringe needles and disposable piston type liquid injection pipe.
Fig. 2, syringe shell backsight face.
Fig. 3, syringe shell front view.
Fig. 4, syringe shell middle part transverse cross-sectional view.
Fig. 5, disposable two sharp formula syringe needle longitudinal sectional drawings.
Fig. 6, disposable two sharp formula syringe needle handle lock housing plane graphs.
Fig. 7, disposable piston type liquid injection pipe longitudinal sectional drawing.
Now be described with reference to the accompanying drawings as follows:
As shown in the figure, two slices watts of shape syringe shells (6) connect together by two concentric shafts (1), (2).Aseptic disposable pair of prong head (9) and aseptic disposable piston type liquid injection pipe (8) are packed in the asepsis injector shell (6), and closed syringe shell (6) is inserted the latch (7) of good syringe, makes syringe shell (6) be a tubular.Syringe top plug (4) in the push-tight retainer ring (5) makes aseptic disposable pair of prong head (9) just pass the valve rubber of aseptic disposable piston type liquid injection pipe (8) front end.Rotary injection device push rod (3), the screw thread that makes its front end interlocks in piston (11) screw thread of aseptic disposable liquid injection pipe.But this moment syringe direct injection and pumpback.After using up, the push rod of loosening (3) is opened syringe shell (6), and disposable two sharp formula syringe needles (9) and disposable liquid injection pipe (8) can integral body be taken out.
Disposable piston type liquid injection pipe (8) is a tubular glass tubing (see figure 7), and its front end is that rubber blanket seals, and metal thin skin hoop is fixed; Its rear portion is that plastic, rubber piston (11) seals.Piston (11) rear plastic partly has the screw thread linkage structure, in order to connect the screw thread linkage structure of injector push-rod (3) front end.
Disposable two sharp formula syringe needle (9) center is that the needle handle rear end lock housing (10) that front and back belt taper metal tube, plastics are made is ellipse.String moved and left-right rotation before and after it can prevent syringe needle.
Disposable aspiration needle (9) and disposable liquid injection pipe (8) are disposable sterilized packing.
The utility model is compared with existing syringe and is had the following advantages:
1, time saving and energy saving, easy and simple to handle, more be conducive in time give emergency treatment to a patient.
2, save material, reduce cost, reduce patient's medical expense.
3, in the whole operation process, do not have and cut a piece of glass, do not have and fracture liquid injection pipe and take out step such as medicine, can reduce opportunities for contamination like this, help the sterile working.
4, in the whole operation process, needle interior wall does not contact with fungus is arranged, and syringe needle and liquid injection pipe are disposable, so eliminated the cross infection chance.
Claims (4)
1, a kind of vertical open-close type syringe of being furnished with disposable pair of prong head and disposable piston type liquid injection pipe, it is characterized in that: two slices watts of shape syringe shells (6) connect together by two concentric shafts (1), (2), are vertical open-close type.Syringe retainer ring (5) be same axle center with top plug (4), push rod (3), and disposable aspiration needle (9) be pair sharp formulas, and disposable liquid injection pipe (8) one ends are that piston (11) seals at the bottom of the screw thread of cone top.
2, vertical open-close type syringe as claimed in claim 1 is characterized in that push rod (3) front end has the screw thread linkage structure.
3, vertical open-close type syringe as claimed in claim 1, the lock housing (10) that it is characterized in that two prong heads (9) is for oval.
4, vertical open-close type syringe as claimed in claim 1 is characterized in that piston (11) end of liquid injection pipe is provided with the screw thread linkage structure.
