Abstract
The utility model discloses compound 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 A chamber that holds solution, piston A, piston B and outer casing inner wall form the B chamber that holds solution, in described conehead, are provided with draw point, and draw point needle point is towards piston A.Injected after the liquid of A chamber, draw point runs through piston A can continue to inject the liquid in B chamber, thereby realizes the object that uses two kinds of different liquids of a syringe sequential injection.
Description
Technical field
This utility model relates to a kind of syringe, relates in particular to once priority to the compound 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 still may cause blood coagulation with pump pickle solution irrigating catheter, 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, therefore 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 use two syringes, can make medical personnel's workload strengthen, also in operating process, increase unnecessary pollution risk.
Summary of the invention
The purpose of this utility model is to provide a kind of compound syringe, and this syringe can be realized the injection in turn of two kinds of different injection solutions, can raise the efficiency, reduce pollution risk for rinsing, seal venous duct.
This utility model is achieved in that a kind of compound 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 A chamber that holds solution, piston A, piston B and outer casing inner wall form the B chamber that holds solution, in described conehead, are provided with draw point, and draw point needle point is towards piston A.
In described A chamber, be packaged with pump pickle solution, in B chamber, be packaged with heparin solution.
The pin hole of described draw point is opened at needle point place, and draw point root is provided with aperture.
Described overcoat front end is provided with helmet.
The beneficial effects of the utility model are: in same syringe, can encapsulate two kinds of different liquids, inject after the liquid of A chamber, draw point runs through piston A can continue to inject the liquid in B chamber, thereby realizes the object that uses two kinds of different liquids of a syringe sequential injection.This syringe construction is simple, easy to use, improves medical personnel's efficiency, effectively reduces pollution risk.

Fig. 1 is the structural representation of the disposable compound syringe of this utility model;
Fig. 2 is draw point structural representation;
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, A chamber; 4, piston A; 5, B chamber; 6, overcoat; 7, piston B; 8, core bar; 9 coneheads; 21, pin hole; 22 apertures.
Detailed description of the invention
Can be found out by Fig. 1 and Fig. 3, the compound 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, between piston B7 and overcoat front end conehead 9, be provided with piston A4, piston A4 and overcoat 6 inwalls form the A chamber 3 that holds solution, and piston A4, piston B7 and overcoat 6 inwalls form the B chamber 5 that holds solution, in described conehead 9, be provided with the draw point 2 of hollow, draw point 2 needle points are towards piston A4.The pin hole 21 of draw point is opened at needle point place, and draw point 2 roots are provided with aperture 22.Overcoat 6 front ends are provided with helmet 1.In the time using this utility model to nurse venous duct, in A chamber, be packaged with pump pickle solution, in B chamber, be packaged with heparin solution.
When use, while promoting core bars 8 and piston B7 composition overall to conehead 9 directions, under the solution thrust of piston A in B chamber 5, also advance to conehead 9 directions, and then make the interior liquid of A chamber 3 move and inject by steel pinhole 21 to conehead direction under the effect of piston A4, along with the continuous minimizing of A chamber 3 interior liquid solutions in syringe, when piston A4 moves to while contacting with draw point 2 needle points, now the entirety of core bar 8 and piston B7 composition continues to promote B chamber 5 interior liquid to conehead direction under the effect of external force, the interior liquid-driving piston of B chamber 5 A4 moves to conehead 9 directions, because draw point needle point is very sharp, and then under the effect of power, penetrate piston A4, after penetrating completely, the interior liquid of B chamber 5 injects by draw point 2.The top of draw point 2 is provided with pin hole 21, is also provided with several apertures 22 on draw point, and sharp needle point is easy to puncture, and aperture is easy to the smooth injection of surplus solution.Use two kinds of liquid of an injector to inject to reduce medical personnel's workload, also reduced antibacterial infection risk unnecessary in operating process.
