Abstract
The utility model provides an once -used syringe, relates to medical supplies preparation technical field, and the main part includes cylinder and piston rod, its characterized in that: the piston rod setting inside the cylinder, the piston rod top be provided with the piston, the piston include upper cover plate and lower apron, the upper cover plate and be provided with down the fixed spring of level between the apron, spring one end fix at the piston rod top, the other end of spring be fixed in on the slider, the slider setting at the upper cover plate under and between the apron, the top slot of cylinder. The beneficial effects of the utility model are that: the utility model discloses simple structure, the modern design, effect through the spring makes the syringe to realize the self -destruction, avoided the syringe in violation of rules and regulations the secondary use, convenient simple, the cost is with low costs, and is costly, just with promote and use.
Description
Technical field
This utility model relates to medical supplies preparing technical field, is specifically related to a kind of re-use preventing once-used syringe.
Background technology
Medical supplies are for process wound or the general name processing disease article used.Medical supplies scope can comprise home medical articles for use, Medical pet articles for use etc., medical supplies from we very close to, from required article of binding up a wound at ordinary times little aspect, medicine bottle, plastics, clear vial, plastic bottle, eye water bottle and liquid medicine bottle are all the categories of medical supplies.From large aspect to operation required for large-scale device product, some device product of body-building at ordinary times are also within comprising, in general, medical supplies are exactly be medical science complementary apparatus used or article, in current medical supplies, the most widely usedly be syringe, syringe is due to its scope of application, general is all single use, in order to be exactly prevent pathophoresis, infect, cause immeasurable consequence, but at present, after disposable syringe uses, if after it reclaims by some illegal enterprise or individual by the gross, it is not rationally processed, after simply processing, again come into the market, very large hidden danger can be caused like this, if but inherently accomplish self-destruction at disposable syringe, just can avoid from farther, but self-destruction syringe at present on the market, its due to its cost too high, can not get batch production.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple and practical, easy to use, the re-use preventing once-used syringe that cost is low.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of re-use preventing once-used syringe, it is characterized in that: main body comprises syringe and piston rod, it is characterized in that: described piston rod is arranged on syringe inside, described piston rod part is provided with piston, described piston comprises upper cover plate and lower cover, the spring that level is fixing is provided with between described upper cover plate and lower cover, described spring one end is fixed on piston rod part, the other end of described spring is fixed on a slide block, described slide block is arranged between upper cover plate and lower cover, top one groove of described syringe.
The junction of described groove and the outer wall of syringe is set to arc, avoids salient angle to hurt operator, safer.
Described groove and syringe are structure as a whole, and structure is more firm.
Described slide block is provided with many groups, and all circumferentially mode is arranged between upper cover plate and lower cover, more stable.
This utility model is in use: when syringe uses, when push rod pushes top to by bottom, piston is by after syringe to groove, and under the action of the spring, slide block can eject, and so just can be stuck in groove, realizes fixing, self-destruction.
The beneficial effects of the utility model are: this utility model structure is simple, novel in design, make syringe realize self-destruction by the effect of spring, avoid syringe in violation of rules and regulations secondary use, convenient and simple, cost is low, is worth high, just with popularization and use.
Accompanying drawing explanation
Fig. 1 is this utility model syringe self-destruction pre-structure schematic diagram;
Fig. 2 is structural representation after the self-destruction of this utility model syringe;
Fig. 3 is the structural representation of piston in this utility model.
Detailed description of the invention
The technological means realized to make this utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth this utility model further.
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of re-use preventing once-used syringe, main body comprises syringe 1 and piston rod 2, it is inner that piston rod 2 is arranged on syringe 1, piston rod 2 top is provided with piston 3, piston 3 comprises upper cover plate 31 and lower cover 32, the spring 33 that level is fixing is provided with between upper cover plate 31 and lower cover 32, spring 33 one end is fixed on piston rod 2 top, the other end of spring 33 is fixed on a slide block 34, slide block 34 is arranged between upper cover plate 31 and lower cover 32, top one groove 4 of syringe 1, when syringe uses, when push rod pushes top to by bottom, piston 3 is by after syringe to groove 4, under the effect of spring 33, slide block 34 can eject, so just, can be stuck in groove 4, realize fixing, self-destruction, groove 4 is set to arc with the junction of the outer wall of syringe 1, salient angle is avoided to hurt operator, safer, groove 4 and syringe 1 are structure as a whole, structure is more firm, slide block 34 is provided with many groups, and all circumferentially mode is arranged between upper cover plate 31 and lower cover 32, more stable.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed this utility model.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
