Description
Technical field
This utility model relates to a kind of doser, relates in particular to once priority to the disposable compound doser 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 doser is provided, for rinsing, seal venous duct.
This utility model is achieved in that disposable compound doser, comprise overcoat and be sleeved on the core bar in overcoat, core bar front end is provided with core bar piston, overcoat is comprised of conehead and outer body, the hollow channel that conehead has liquid to flow out, hollow channel gos deep into outer body, between described core bar piston and outer taper, be provided with every liquid piston, A chamber every liquid piston and outer casing inner wall formation filling liquid, every liquid piston, core bar piston and outer casing inner wall form the B chamber of filling liquid, described have a motion stops with described hollow channel opposite position on liquid piston, after coordinating with hollow channel, motion stops forms the outlet of B chamber liquid on liquid piston.
There is aperture that can influent described hollow channel and outer body joint, every liquid piston, be provided with liquid communication passage, before contacting with hollow channel, motion stops is blocked liquid communication passage, prevent that B chamber liquid from flowing in A chamber, described after liquid piston is pulled to and contacts with hollow channel, every liquid piston and outer inner room, form a cone section chamber, described motion stops is by described hollow channel jack-up, liquid communication passage becomes the outlet of B chamber liquid, and B chamber liquid flows in cone section chamber and flows out through small holes.
The beneficial effects of the utility model are, the compound doser of this utility model is two kinds of different medicinal liquids of fill in advance, use same device to realize the successively administration of two kinds of liquid, alleviated medical personnel's workload, also avoid producing antibacterial infection risk in changing the process of syringe.
Accompanying drawing explanation
Fig. 1 is the cutaway view of this utility model while not using;
Fig. 2 is the anterior enlarged drawing of Fig. 1;
Fig. 3 be in this utility model A chamber liquid infusion complete after, cutaway view when liquid is released in B chamber;
Fig. 4 is the anterior enlarged drawing of Fig. 3;
In figure, each label declaration is as follows: 1, overcoat, 2, every liquid piston, 3, core bar piston, 4, core bar, 5, conehead, 6, outer body, 7, hollow channel, 8, aperture, 9, A chamber, 10, B chamber, 11, liquid communication passage, 12, motion stops, 13, a cone section cavity.
The specific embodiment
Below in conjunction with accompanying drawing 1-Fig. 4, this utility model is described in further details.
Disposable compound doser, comprises overcoat 1, every liquid piston 2, core bar piston 3, core bar 4.Core bar piston 3 is connected with core bar 4, is sleeved in overcoat 1.
Described overcoat 1 comprises conehead 5, outer body 6, the hollow channel 7 that conehead 5 has liquid to flow out, hollow channel 7 gos deep into outer body 6, and with outer body 6 joints have can influent aperture 8.
Every liquid piston 2 and overcoat 1 inwall, form the A chamber 9 of filling liquid, core bar piston 3, the B chamber 10 every liquid piston 2 with overcoat 1 inwall formation filling liquid.Every liquid piston 2, shift onto while being about to contact with hollow channel 7, in A chamber 9, still have liquid, aperture 8 can prevent from going deep in outer body 6 longly due to hollow channel 7, and the liquid in A chamber 9 cannot be released completely, and B chamber 10 liquid can flow follow-up afterflow at A chamber 9 liquid and go out simultaneously.
On liquid piston 2, there are two liquid communication passages 11, in the middle of liquid piston 2, there is a motion stops 12 with hollow channel 7 opposite positions, two liquid communication passages 11 are blocked by motion stops 12, prevent that in B chamber 10, liquid flows in A chamber 11, promote described core bar 4, core bar piston 3 is pushed, the interior liquid of A chamber 9 is pushed out by hollow channel 7, after liquid piston 2 is pulled to and contacts with hollow channel 7, every liquid piston 2 and 1, overcoat, form cone section chamber 13, liquid in residue A chamber 9 continues to flow out through small holes 8, motion stops 12 on liquid piston 2 is by hollow channel 7 jack-up, in B chamber 10, liquid flows in described cone section chamber 13 through two liquid communication passages 11, then through small holes 8, entering hollow channel 7 flows out.
In sum, this compound doser can be realized the successively administration of two kinds of liquid in a device, has saved the process of changing syringe, has avoided producing in Renewal process the risk infecting.
