Abstract
This utility model discloses a kind of compound flushing syringe, comprise overcoat and be sleeved on the core bar in overcoat, described core bar front end is connected with piston B, between piston B and overcoat front end conehead, be provided with piston A, piston A and outer casing inner wall form the chamber that holds pump pickle solution, piston A, piston B and outer casing inner wall form the chamber that holds heparin solution, in described conehead, are provided with draw point, and draw point needle point is towards piston A.Injected after pump pickle solution, draw point runs through piston A can continue to inject heparin solution, thereby realizes the object of using a syringe order washing pipe.
Description
Technical field
This utility model relates to a kind of syringe, relates in particular to once priority to the compound flushing syringe of two kinds of different medicines.
Background technology
Venous duct is a kind of conventional therapy equipment, and arranging of venous duct can conveniently be treated, for example, can medicine be input in human body by venous duct, and these conduits need to rinse to keep catheter patency and complete, the fluid of irrigating catheter, has pump pickle solution, heparin etc.And for the sufferer of infusing every other day, only with pump pickle solution irrigating catheter, still may cause blood coagulation, cause plugging, if seal conduit and use heparin solution to rush, may make the heparin content of human body infusion too high, produce harmful effect, so in nursing process, preferably use pump pickle first conduit to be rinsed, and then use heparin solution closes ducts.If employing aforesaid operations, need to be used two syringes, can make medical personnel's workload strengthen, also in operating process, increased unnecessary antibacterial infection risk.
Summary of the invention
The purpose of this utility model is to overcome uses two defects that syringe is nursed conduit, and a kind of compound flushing syringe is provided, for rinsing, seal venous duct.
This utility model is achieved in that a kind of compound flushing syringe, comprise overcoat and be sleeved on the core bar in overcoat, described core bar front end is connected with piston B, between piston B and overcoat front end conehead, be provided with piston A, piston A and outer casing inner wall form the chamber that holds pump pickle solution, piston A, piston B and outer casing inner wall form the chamber that holds heparin solution, in described conehead, are provided with draw point, and draw point needle point is towards piston A.
The needle point of described draw point is sharp, and head side face is arranged with two oblong pin holes, and root is provided with aperture.
Described overcoat front end is provided with helmet.
Major advantage of the present utility model is: in same flushing syringe, can encapsulate pump pickle solution and heparin solution, injected after pump pickle solution, draw point runs through piston A can continue to inject heparin solution, thereby realizes the object of using a syringe order washing pipe.In addition, the pin hole of draw point is symmetrical oblong side opening structure can avoid puncturing time, and the powder of piston stops up pin hole, causes liquid to flow out.Root aperture is easy to the smooth injection of front end residue pump pickle solution.
Accompanying drawing explanation
Fig. 1 is the structural representation of the disposable compound flushing syringe of this utility model;
Fig. 2 is the structural representation of this utility model draw point;
Fig. 3 is the schematic diagram while having injected A chamber indoor liquid;
Fig. 4 is the partial enlarged drawing of puncture of steel needles piston A
In figure: 1, helmet; 2, draw point; 3, pump pickle solution; 4, piston A; 5, heparin solution; 6, overcoat; 7, piston B; 8, core bar; 9 coneheads; 21, pin hole; 22 apertures.
The specific embodiment
By Fig. 1 and Fig. 3, can be found out, the compound flushing syringe of this utility model, comprise overcoat 6 and be sleeved on the core bar 8 in overcoat 6, described core bar 8 front ends are connected with piston B7, piston B7 and 9 of overcoat front end coneheads are provided with piston A4, and piston A4 and overcoat 6 inwalls form the chamber that holds pump pickle solution 3, and piston A4, piston B7 and overcoat 6 inwalls form the chamber that holds heparin solution 5, in described conehead 9, be provided with the draw point 2 of hollow, draw point 2 needle points are towards piston A4.The needle point of described draw point 2 is sharp, and head side face is arranged with the oblong pin hole 21 of two, and root is provided with aperture 22.
During use, to conehead 9 directions, promote that core bars 8 and piston B7 form whole time, piston A also advances to conehead 9 directions under heparin solution 5 thrust, and then make pump pickle solution 3 to conehead direction, move and inject by pin hole 21 under the effect of piston A4, continuous minimizing along with pump pickle solution in syringe, when piston A4 moves to while contacting with draw point 2 needle points, the integral body that now core bar 8 and piston B7 form continues to promote heparin solution 5 to conehead 9 directions under the effect of external force, heparin solution 5 promotes piston A4 and moves to conehead 9 directions, because draw point needle point is very sharp, and then under the effect of power, penetrate piston A4, when penetrating postheparin solution 5 completely, by draw point 2, inject.In washing pipe process, use a syringe to rush the workload that two kinds of liquid of note have reduced medical personnel, also reduced antibacterial infection risk unnecessary in operating process.
Claims (3)
1. a compound flushing syringe, comprise overcoat and be sleeved on the core bar in overcoat, described core bar front end is connected with piston B, it is characterized in that: between piston B and overcoat front end conehead, be provided with piston A, piston A and outer casing inner wall form the chamber that holds pump pickle solution, piston A, piston B and outer casing inner wall form the chamber that holds heparin solution, in described conehead, are provided with draw point, and draw point needle point is towards piston A.
2. compound flushing syringe according to claim 1, is characterized in that: the needle point of described draw point is sharp, and head side face is arranged with two oblong pin holes, and root is provided with aperture.
