Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of small-sized medicine injection pen for medication injections.
Background technology
In hospital, the apparatus pin overwhelming majority for Patient drug's injection is disposable.But along with economical environment-protective becomes a large theme of existing society, those disposable products need to improve undoubtedly.
Injection pen arises at the historic moment for this reason, and the principle of conventional injection pen can so be understood substantially: set injection volume as required, then turn push rod, till can not turning, just completes calibrated shot.What this injection pen adopted is rotate injection, if patient oneself injection, hands carries out operating often, and the amount of injection is just so inaccurate yet.
Summary of the invention
In order to solve the problem, the technical solution of the utility model provides a kind of push-in type non-replaceable medicated core type calibrated shot pen.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of push-in type non-replaceable medicated core type calibrated shot pen, comprise spiral cover, push rod, penholder, locating cover, clamped bottle and protecting cover, described penholder inwall is provided with positioning table and guiding rib, described push rod is provided with rotation positioning boss, described spiral cover is arranged on described push rod upper end, described locating cover is arranged on described penholder topmost, described clamped bottle is arranged on described push rod bottom, described protecting cover and described penholder are together by a threaded connection, described penholder shell is also provided with pen hanging.
Feature of the present utility model is, adopts the Simple mechanical structure of guiding rib and gradient limiting stand, achieves accurate calibrated shot, simple to operate, has and well promotes the use of prospect.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 2: this utility model structure of pen holder figure.
Fig. 3: this utility model pusher structure figure.
Wherein, 1, spiral cover; 2, locating cover; 3, pen hanging; 4, clamped bottle; 5, protecting cover; 6, penholder; 7, push rod; 8, guiding rib; 9, positioning table; 10, positioning boss is rotated.
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.
Fig. 1 in accompanying drawings, shown in Fig. 2 and Fig. 3, a kind of push-in type non-replaceable of this utility model medicated core type calibrated shot pen, comprise spiral cover (1), push rod (7), penholder (6), locating cover (2), clamped bottle (4) and protecting cover (5), described penholder (6) inwall is provided with positioning table (9) and guiding rib (8), described push rod (7) is provided with and rotates positioning boss (10), described spiral cover (1) is arranged on described push rod (7) upper end, described locating cover (2) is arranged on described penholder (6) topmost, described clamped bottle (4) is arranged on described push rod (7) bottom, described protecting cover (5) and described penholder (6) are together by a threaded connection, described penholder (6) shell is also provided with pen hanging (3).
Operation principle
1, spiral cover: facilitate rotating push rod, makes push-and-pull push rod convenient;
2, locating cover: pulling back of push rod is spacing, pushes away mast switch and limits mouth, the locating slot that push rod rotates, the reading form of quantitative transfusion, and the spacing draw-in groove of switch of injection positive stop lug boss, has positioner to be fixed on penholder;
3, pen hanging: can insert when carrying and hang in coat pocket;
4, clamped bottle: the medicinal liquid of hoarding demand infusion, and facilitate patient oneself to inject with injection pen cooperation;
5, protecting cover: the contact pin mouth of protection clamped bottle, unwinding thread during use, sterilizes and screws on entry needle;
6, penholder: fix with locating cover, contains the guide rail that push rod slides, the limiting stand etc. of quantitative transfusion;
7, push rod: promote clamped bottle piston and move the switch comprising location, the positioning boss of limitation transfusion, rotates the elasticity boss for locating, the capacity colour code of quantitative transfusion and capacity Grad.
Operation instruction
1, before using, scale is rotated to the scale gradient of needs;
2, in use procedure, promote spiral cover, transfusion positioning table is finally fixed on corresponding limiting stand.When again injecting, pumpback push rod, rotates to next gradient scale, presses syringe to push rod can not move, has namely injected;
3, at the end of transfusion, final scale arrives above form.
The feature of this technical scheme is:
1, this Simple mechanical of the limiting stand structure of guiding rib and gradient type is adopted to achieve accurate calibrated shot;
2, have employed the Simple mechanical structure rotating locating slot and elastic rotation positioning boss, achieve the transfer transposition of different gradient in accurate injection process;
3, easy window structure makes patient can clear injected dose;
4, the front limit boss of positioning table makes patient inject and promotes sensation obviously;
5, switch boss and switch limited mouth ensure that injection can not occur before pressing;
6, pen-hanging type structure makes to portably use conveniently.
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.
