Description
Technical field
This utility model relates to the pre-filled tube sealing syringe that rushes of a kind of disposable use.
Background technology
The existing pre-filled tube sealing syringe that rushes, because piston is quality of rubber materials, ordinary syringe is being rushed to conduit in tube sealing process, and syringe piston is shifted this stage of syringe head end onto.When earth pressure release, piston will push and resilience, produces one simultaneously and causes blood to get back to the region of no pressure in conduit, produces blood back effect, is unfavorable for injection, and patient has been caused to impact.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly can reduces above-mentioned blood back problem, can also reduce the risk of conduit breakage, can also reduce acupuncture and injure the risk that ampoule is stabbed, also there is the at the uniform velocity pre-filled tube sealing syringe that rushes of disposable use of loading function simultaneously simultaneously.
For addressing the above problem, this utility model adopts following technical scheme:
The pre-filled tube sealing syringe that rushes of a kind of disposable use, comprise protective cap, overcoat, 0.9% sodium chloride solution, jam device, piston and core bar, described jam device is arranged on the medium position place of outer casing inner wall, described piston is arranged on overcoat inner side, and keep sealing to form a sealed cavity with overcoat, described piston nose and jam device offset, rear end is connected with core bar front end, described core bar rear end extends to overcoat outside, described protective cap is arranged on overcoat front opening place, described 0.9% sodium chloride solution is filled in piston and the formed sealed cavity of overcoat, the rear end of described overcoat is coated with a shell, between described shell and overcoat, by glue, bond fixing, described enclosure is provided with a rubber utricule offseting with described core bar, described rubber utricule has an inlet end, described inlet end extends to housing exterior.
As preferred technical scheme, described core bar rear end is provided with a force-application block, and described overcoat rear end is provided with the force application board being used in conjunction with force-application block.
As preferred technical scheme, described sleeve pipe front end is provided with conehead, and described conehead is 6% Rule cone locking joint.
The beneficial effects of the utility model are:
1, disposable use in advance the formula of rushing rush tube sealing syringe by reducing the elasticity of piston, reduce extruding and the resilience of piston, reach the effect that reduces blood back;
2, because the pressure of the less generation of diameter of syringe is larger.The overcoat caliber design that all specifications of tube sealing syringe all adopt 10mL ordinary syringe is rushed in the disposable use in advance formula of rushing, thereby reduces the risk of conduit breakage;
3, disposable use in advance the formula of rushing to rush tube sealing syringe be that female Luer and other medical apparatus and instruments by overcoat supports the use, all adopt needleless to connect, thereby reduce acupuncture, injure the risk that ampoule is stabbed.
4,, by set rubber utricule, this device, when drug delivery, by the inner input uniformly of rubber utricule gas, makes core bar promotion at the uniform velocity, guarantees the uniformity of drug delivery, can, according to injection needs, accelerate or reduce the speed of loading simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the pre-filled structural representation that rushes tube sealing syringe of the disposable use of this utility model.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Consult the pre-filled tube sealing syringe that rushes of a kind of disposable use shown in Fig. 1, comprise protective cap 1, overcoat 2, 0.9% sodium chloride solution 3, jam device 4, piston 5 and core bar 6, described jam device 4 is arranged on the medium position place of overcoat 2 inwalls, described piston 5 is arranged on overcoat 2 inner sides, and keep sealing to form a sealed cavity with overcoat 2, described piston 5 front ends and jam device 4 offset, rear end is connected with core bar 6 front ends, described core bar 6 rear ends extend to overcoat 2 outsides, described protective cap 1 is arranged on overcoat 2 front opening places, described 0.9% sodium chloride solution 3 is filled in piston 5 and the formed sealed cavity of overcoat 2, the rear end of described overcoat 2 is coated with a shell 10, between described shell 10 and overcoat 2, by glue, bond fixing, described shell 10 inside are provided with a rubber utricule 11 offseting with described core bar 6, described rubber utricule 11 has an inlet end 12, described inlet end 12 extends to shell 10 outsides.
Wherein, described core bar 6 rear ends are provided with a force-application block 7, and described overcoat 2 rear ends are provided with the force application board 8 being used in conjunction with force-application block 7.
Described sleeve pipe 2 front ends are provided with conehead 9, and described conehead 9 is 6% Rule cone locking joint.
The beneficial effects of the utility model are:
1, disposable use in advance the formula of rushing rush tube sealing syringe by reducing the elasticity of piston, reduce extruding and the resilience of piston, reach the effect that reduces blood back;
2, because the pressure of the less generation of diameter of syringe is larger.The overcoat caliber design that all specifications of tube sealing syringe all adopt 10mL ordinary syringe is rushed in the disposable use in advance formula of rushing, thereby reduces the risk of conduit breakage;
3, disposable use in advance the formula of rushing to rush tube sealing syringe be that female Luer and other medical apparatus and instruments by overcoat supports the use, all adopt needleless to connect, thereby reduce acupuncture, injure the risk that ampoule is stabbed.
4,, by set rubber utricule, this device, when drug delivery, by the inner input uniformly of rubber utricule gas, makes core bar promotion at the uniform velocity, guarantees the uniformity of drug delivery, can, according to injection needs, accelerate or reduce the speed of loading simultaneously.
The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
