Description

Cassette bottle full-automatic syringe

Technical field

This utility model relates to a kind of automatic injector, specifically a kind of cassette bottle full-automatic syringe.

Background technology

" automatically injection technique " be meant without medical personnel's operation or instruct, by non-medical staff such as soldier in the battlefield, the patient injects the injection technique of first aid, treatment voluntarily inside and outside hospital.Automatic injecting needle is equipped in a few countries such as Sweden, the U.S., France, Russia small lot and is engaged in the specialized force that anti-chemical weapon, bacteriological protection weapon, protection against atomic weapons kill and wound, and is used for the interim first aid in battlefield.And be applied to the injection that also is only limited to medicines such as insulin or growth hormone of common medical field.But the structure of this automatic injecting needle is very complicated, and production cost is also high, automatic injecting needle at home selling price about 200 yuan.China is also once relevant for the patent report of automatic injecting needle, but its structure is not too complicated, is difficult to processing and manufacturing, designs unreasonablely exactly, and performance is stable inadequately, and it is also not too convenient to use.In addition, the injection operation link is more, and the program complexity is professional more intense.Such as sucking water for injection earlier sometimes, reinject and mix medicine in the powder injection bottle, and then sucking-off medicinal liquid and discharge air and could implement injection, this operation is that general non-medical staff can not be grasped easily, for promptly save oneself or daily self-injection treatment very inapplicable.

Summary of the invention

The technical problems to be solved in the utility model is for overcoming the deficiencies in the prior art, and a kind of novel structure, easy to operate is provided, and can realize the cassette bottle full-automatic syringe of fast automatic injection.

Technical solution of the present utility model is:

This cassette bottle full-automatic syringe comprises a cassette bottle that medicinal liquid is housed, the slippage frame that is fixed with the conducting pin is engaged in the bottle mouth position of cassette bottle, a piston is positioned at the cassette bottle, mainly be that core bar is installed in the cover, the push-rod hole that is provided with chute in the core bar and communicates with chute, the push rod that has fixture block vertically penetrates cover and push-rod hole, is equipped with spring between push rod and the last cover inwall, is equipped with spring between core bar top and the last cover.

Its further technical solution is:

Push rod is a strip shape body, and said fixture block is positioned at the termination of push rod, and fixture block and push-rod hole are for being slidingly matched, and chute and push rod are also for being slidingly matched.The lower end and the piston of core bar join.Be fixedly connected with the cover card last putting, the outer end of push rod is embedded in the opening of cover card.

As can be seen from the above technical solutions, this utility model adds the active force of upper spring owing to adopted cooperating of core bar and push rod and fixture block, when promoting push rod and making the push-rod hole of fixture block disengaging core bar, core bar will be oppressed the piston motion under the pressure of spring, thereby medicinal liquid is released.This injector operations is very simple, only need press the push rod termination and just can realize the purpose of injection automatically, is particularly suitable for being equipped on special trade and hospital, emergency tender etc. and is used for urgent rescue.Because simple to operate, also can be used for family, individual's self-injection treatment.

The specific embodiment

As shown in Figure 1, this utility model is divided into upper and lower two parts.

The cover card 9 that top is connected as a single entity by last cover 7, with last cover 7, the core bar 6, spring 8, the termination that are positioned at cover 7 have the push rod 10 of fixture block 15, the spring 5 that cooperates with push rod 10 constitutes.Wherein, core bar 10 vertically is positioned at cover 7, the step place on core bar 6 tops with on overlap between 7 tops and be provided with spring 8.Along core bar 6 vertically have a chute 14, the lower end of this chute 14 is provided with the push-rod hole 16 (referring to Fig. 3) that the fixture block 15 with push rod 10 terminations adapts.Said fixture block 15 only is located at the front end of strip push rod 10 and as a whole with push rod 10, and its cross section is cross or convex shape (referring to Fig. 3, Fig. 5).The width of push rod 10 or diameter are slightly less than the width of chute 14 in the core bar 6; The width of fixture block 15 then should be greater than the width of chute 14.Be provided with one with corresponding position, push rod 10 termination and can place a spring 5 in this pit 17 to hold the pit 17 of fixture block 15 down completely in last cover 7, an end of spring 5 extend into fixture block 15 and push rod 10 inside (referring to Fig. 2).In the opening 18 of the cover card 9 that it is one that the other end of push rod 10 embeds with last cover 7, this cover card 9 can be protected push rod 10 unlikely generation misoperations.

The lower part mainly contains a cassette bottle 11 that medicinal liquid is housed, the piston of being made by butyl rubber 4 is positioned at cassette bottle 11, be sliding combined with slippage frame 2 on the bottleneck of cassette bottle 11, the hollow conducting pin 12 of two ends band point is fixed on the slippage frame 2, the conducting pin 12 outer monobutyl rubber sleeves 13 that are with.Be with a sheath 3 outside cassette bottle 11 and the conducting pin 12, these sheath 3 tops are connected with last cover 7, and the lower end is provided with a pin hole 1 that conducting pin 12 is passed through.Core bar 6 lower ends and the piston 4 on top are interconnection.

This utility model is when configuration state as shown in Figure 1, and spring 8 is in compressive state, and the fixture block 15 of push rod 10 terminations just in time is positioned at push-rod hole 16, and chute 14 lower ends are located on the fixture block 15, and fixture block 15 does not enter in the pit 17 yet.Slippage this moment frame 2 does not have action yet, and conducting pin 12 does not also pierce through the plug of cassette bottle 11.When needing injection, with sheath lower end aligned injection site, with hands push rod 10 terminations are pressed into, 5 on spring is in compressive state, the fixture block 15 of front end has broken away from push-rod hole 16 and has entered in the pit 17 (referring to Fig. 4), under the effect of spring 8, compressing core bar 6 moves downward (push rod 10 moves upward relatively along chute 14 simultaneously), and core bar 6 lower ends are oppressed piston 4 again and moved downward together with cassette bottle 11.Conducting pin 12 thrusts the suffered counteracting force of skin makes slippage frame 2 upwards slide along bottleneck again, makes conducting pin 12 upper ends pierce through the plug of cassette bottle 11 simultaneously.Under the pressure of spring 8, gradually the medicinal liquids in the cassette bottle 11 are injected human body (referring to Fig. 6) by core bar 6, piston 4, finish once the overall process of injection automatically.

Because butyl rubber cover 13 is not only thin but also soft, can protect conducting pin 12 to be in aseptic condition at ordinary times.And conducting pin 12 also pierces through rubber sleeve 13 when injection, and rubber sleeve 13 finally is compressed between slippage frame 2 and sheath 3 lower ends under pressure, can not influence injection operation at all.
