Abstract
The utility model discloses a new style disposable syringe which is a medical appliance used by medical care personnel for puncture, let blood and injection. The utility model is composed of a nipple, a hollow cylinder, a side ear, a piston, a piston hole, an annular protrusion, a front protrusion of a piston rod, a piston rod, a piston rod shaft and a piston rod handle. The utility model is characterized in that the piston rod and the piston rod shaft form a cylinder shape. Compared with the existing disposable syringes, the utility model has the advantages of convenient operation and the avoidance of rubbing fingers.
Description
This utility model belongs to medical instruments field, specifically, is exactly a kind of novel disposable syringe.
Present domestic used disposable syringe, piston rod, piston rod are four prismatics, not only operation inconvenience, and mill hands.The nurse has an injection, the laboratory blood drawing, and emergency department's rescue etc., everyone class often will operate up to a hundred person-times, and finger is ground with bleeding blister sometimes.
It is the disposable syringe of garden cylindricality that the purpose of this utility model is to provide a kind of piston rod and piston rod.
The purpose of this utility model is achieved in that
This novel disposable syringe, by nipple (1), empty tube (2), pick up the ears (3), and piston (4), piston hole (5), annular projection (6), piston rod prolapse (7), piston rod (8), piston rod (9), piston rod handle (10) is formed.It is characterized in that: piston rod (8) and piston rod (9) are the garden cylindricality.Piston rod prolapse (7) is " protruding " font, and piston (4) is made by rubber-like hollow type synthetic rubber, and periphery has three annular projections (6) that are higher than piston (4), piston rod prolapse (7) is inserted in the piston hole (5) be connected.Except that piston (4), all the other are made by plastics.Below in conjunction with accompanying drawing this utility model is described in detail:
Accompanying drawing 1 is an empty tube sketch map of the present utility model.
Accompanying drawing 2 is piston sketch maps of the present utility model.
Accompanying drawing 3 is piston rod sketch maps of the present utility model.
As shown in Figure 1, be provided with scale above the empty tube (2) of this novel disposable syringe, to show the volume of medicinal liquid, nipple (1) will be connected with injection needle.
As shown in Figure 2, piston (4) is identical with the piston of present used disposable syringe, make by hollow rubber-like synthetic rubber, periphery has three annular projections (6) that are higher than piston (4), so that it is tightly close with empty tube (2), form the negative pressure-pumping medicinal liquid during pumpback, piston hole (5) is arranged on the piston (4), so that " protruding " font piston rod prolapse (7) inserts and to be connected, when piston rod (8) when pulling back, simultaneously with piston (4) post-tensioning in the lump, medicinal liquid enters in the empty tube (2) with negative pressure, when piston rod (8) and preceding the pushing away of piston (4), medicinal liquid increases with pressure and is pushed out, in injection needle injects body or carry out the medicinal liquid dilution.
The advantage of this novel disposable syringe is: piston rod (8) and piston rod (9) are the garden cylindricality, and be both easy to operate, do not grind finger again, and good practical values and social benefit are arranged.
Claims (1)
1, a kind of novel disposable syringe, be made up of nipple (1), empty tin (2), pick up the ears (3), piston (4), piston hole (5), annular projection (6), piston rod prolapse (7), piston rod (8), piston rod (9), piston rod handle (10), it is characterized in that: piston rod (8) and piston rod (9) all are the garden cylindricality.
