Abstract

The utility model discloses a detachable type pre-filling syringe, which comprises an outer sleeve, a sleeve cap, a rubber plug and a core rod, wherein, particularly, the rubber plug is detachably connected with the core rod, the rubber plug is glidingly connected with the inner wall of the outer sleeve, the outer sleeve is provided with a sleeve port, and the sleeve port is connected with the sleeve cap. The detachable type pre-filling syringe has the advantages that by adopting the rubber plug and the core rod which can be detachably connected, when the syringe is packaged, the rubber plug and the core rod can be separately packaged, so the problem of liquid leakage of the detachable type pre-filling syringe during transportation is effectively avoided; meanwhile, the packaging of the syringe is convenient, and the packaging difficulty is reduced.

Description

Detachable pre-charge injector
Technical field
This utility model relates to a kind of pre-charge injector, relates in particular to a kind of detachable pre-charge injector, belongs to technical field of medical instruments.
Background technology
Precharging type syringe has following characteristics: during use, without cross infection, in ward, unclean air does not reach medicine, accomplishes safety injection; Doctors and nurses is extremely easy to use, without taking out medicine, without syringe needle, direct injection, disposable use are installed; Some high-grade medicines make full use of, noresidue medicinal liquid; Field occasion is applicable to self-injection etc.
Precharging type syringe is after liquid drug, need to pack and transport, precharging type syringe of the prior art is integrated packing, because core bar is positioned at overcoat outside, comparatively inconvenience during packing, and easily bump in transit, there is the problems such as leakage, bring economic loss, the precharging type syringe that volume is larger also can increase packing difficulty, causes the wasting of resources simultaneously.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem, proposes a kind of detachable pre-charge injector.
The purpose of this utility model, will be achieved by the following technical programs:
Detachable pre-charge injector, comprises that overcoat, cover emit, plug and core bar, especially, between described plug and core bar, has the mechanism of removably connecting, and described plug is slidably connected to outer casing inner wall, is describedly arranged with running-on outward, and described running-on emits and is connected with cover.
Preferably, the mechanism that removably connects described in is screw thread mechanism or the bayonet socket mechanism that removably connects that removably connects.
Preferably, described running-on emits for being threaded with cover.
Preferably, described core bar is three rib core bars.
The beneficial effects of the utility model are mainly reflected in: apply detachable pre-charge injector of the present utility model, the plug that employing removably connects and core bar, during the packing of product, can be by plug packing separated with core bar, effectively prevent that detachable pre-charge injector from the problem of leakage occurring in transit, be convenient to the packing of product simultaneously, reduced packing difficulty.
Accompanying drawing explanation
Fig. 1 is the structural representation of the detachable pre-charge injector of this utility model.
Fig. 2 is the removably connect structural representation of mechanism of bayonet socket in the detachable pre-charge injector of this utility model.
Fig. 3 is the removably connect structural representation of mechanism of screw thread in the detachable pre-charge injector of this utility model.
Fig. 4 is the cross section structure schematic diagram of three rib core bars in the detachable pre-charge injector of this utility model.
The specific embodiment
This utility model provides detachable pre-charge injector, as shown in Figure 1, comprise that overcoat 1, cover emit 2, plug 3 and core bar 4, especially, between plug 3 and core bar 4, there is the mechanism of removably connecting, plug 3 is slidably connected to overcoat 1 inwall, overcoat 1 is provided with running-on 11, and running-on 11 emits 2 to be connected with cover, by removably connecting of plug 3 and core bar 4, product can adopt the separated packing of plug and core bar in when packing, reduce packing difficulty, prevent from producing in transit leakage, when product is used, take packing apart, plug is connected with core bar.
Concrete, as shown in Figures 2 and 3, the mechanism that removably connects between plug 3 and core bar 4 is screw thread mechanism or the bayonet socket mechanism that removably connects that removably connects, and is threaded and can makes plug steadily be connected with core bar, and bayonet socket is convenient and fast connection.Running-on emits for being threaded with cover, is threaded and has certain closure, is convenient to the preservation of liquid drug.
In addition, for optimizing detachable pre-charge injector, as shown in Figure 4, core bar is three rib core bars, and three rib core bars possess constitutionally stable feature equally compared to four rib core bars, more saves material simultaneously.
This utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming, within all dropping on protection domain of the present utility model.
