Abstract
The invention discloses an antipollution dosing device, which belongs to a field of medical devices and aims at providing a dosing injector with a simple structure, good sealing property and convenient use. The key technical point comprises an injector and a push handle; among whicn, a slide sleeve is arranged on the upper part of the injector, and the external end of the slide sleeve is connected with the push handle in a sealing way; a tubular cavity which can accommodate the slide sleeve is arranged at an injector wall which is corresponding to the slide sleeve which can slide along the tubular cavity; an elastic sealing ring is arranged at a near end part at the internal end of the slide sleeve. The drug adding device provided by the invention is used for dosing preparation.
Description
Technical field
The present invention relates to a kind of medical device, more particularly, it relates to a kind of a kind of antipollution medicine adding device of the allotment of dosing clinically.
Background technology
At present, the medicine adding syringe that generally uses in the hospital is common syringe, is made up of syringe, piston and push rod, and medical personnel move by push rod push-and-pull piston when operation, realize operations such as aspiration medicinal liquid, admixing medical solutions.But find that in actual use medical personnel are when carrying out operation such as aspiration medicinal liquid, admixing medical solutions, finger can touch push rod, exist medicinal liquid contaminated may, cause cross infection easily.For avoiding medical personnel's pollution to medicinal liquid when using syringe, Chinese patent CN200510100206.2 (open day: on March 22nd, 2006) disclose a kind of no pushing rod anti-pollution injector, by Sealed casing pipe being set on syringe top, no push-rod piston in the drive syringe moves up and down the effect that reaches suction or discharge medicinal liquid, has solved conventional syringe and has pointed the deficiency that contacts push rod and easily cause cross-contamination.But in the such scheme, because the possibility that the elastic packing cushion rubber also exists gas leakage or pollutant to enter, thereby also have security breaches, be necessary to improve.
Summary of the invention
The technical problem to be solved in the present invention is at the deficiencies in the prior art, provide a kind of simple in structure, use antipollution medicine adding device more easily.
Technical scheme of the present invention is such: a kind of antipollution medicine adding device, comprise syringe and handle, wherein, described syringe top is provided with sliding sleeve, the outer end and the handle of sliding sleeve are tightly connected, be provided with the tubular cavity that can hold this sliding sleeve with the corresponding syringe barrel of sliding sleeve, sliding sleeve can slide along this tubular cavity; Inner close end at sliding sleeve is provided with elastic sealing ring.
Above-mentioned a kind of antipollution medicine adding device, it is characterized in that, the peristome of described syringe is provided with sealing plate, sealing plate is provided with the ventilation pore, be connected with the molecular film air filter in the passage outside, the pollutant that enter from elastic sealing ring be can further prevent like this, health, safety guaranteed to use.
In above-mentioned a kind of antipollution medicine adding device, described syringe is provided with coloured float, can be used to refer to the liquid level in the syringe, makes things convenient for the medical worker to observe in use.
In above-mentioned a kind of antipollution medicine adding device, describedly be connected with guide pipe in the passage inboard, liquid flows out from the molecular film air filter in the time of can preventing that the drug feeding device syringe needle from upwards taking out medicine, makes the use of syringe convenient.
The present invention compared with prior art has following advantage: owing to cancelled the push rod and the piston that contacts medicinal liquid of contact finger, directly utilize sliding sleeve to move the negative pressure-pumping medicinal liquid of formation, have advantage simple in structure, easy to use; After further improving, utilize the molecular film air filter to isolate the pollutant that may enter from elastic sealing ring, to the cross-contamination of medicinal liquid, guarantee drug safety when preventing operating syringe effectively.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the present invention is described in further detail, but does not constitute any limitation of the invention.
