Abstract
The utility model discloses a drug-adding injector without a pushing rod, which aims at providing a drug-adding injector with simple structure and convenient operation. The injector adopts the technical proposal that the injector comprises a syringe and a pushing handle, wherein a sliding sleeve is arranged at the upper part of the syringe, the outer end of the sliding sleeve is connected with the pushing handle in a sealing way, a tubular cavity which can hold the sliding sleeve is arranged on the wall of the syringe corresponding to the sliding sleeve, and the sliding sleeve can slide along the tubular cavity; an elastic sealing ring is arranged at the adjacent end part of the inner end of the sliding sleeve, a sealing plate is arranged at the opening part of the syringe, an aeration tube hole is arranged on the sealing plate, a molecular film air filter is connected at the outer side of the aeration hole, and a conduit tube is connected at the inner side of the aeration hole; by adopting the structure, the pollution brought by the pushing rod piston type syringe is completely prevented, and the injector is used for drug-adding and medicine blending.
Description
Technical field
This utility model relates to a kind of syringe, refers in particular to the no push rod medicine adding syringe that is used for the dosing allotment.
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 there are security breaches, applicant of the present utility model improves according to above-mentioned deficiency, patent application (the application number: 200720051359.7 of " a kind of no push rod medicine adding syringe " has been proposed, the applying date: on May 14th, 2007), but this technical scheme is in implementation process, find that syringe can only the downward aspiration medicinal liquid of syringe needle, when upwards extracting, medicinal liquid may flow out from the molecular film air filter, and use inconvenience is normally used and caused in influence.
The utility model content
The technical problems to be solved in the utility model provide a kind of not only simple in structure, use more conveniently, and reduce the no push rod medicine adding syringe of the pollution of use.
The technical solution of the utility model is such: a kind of no push rod medicine adding syringe, comprise syringe and handle, be provided with sliding sleeve on syringe top, 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, and the peristome of wherein said syringe is provided with sealing plate, and sealing plate is provided with the ventilation pore, is connected with the molecular film air filter in the passage outside, is connected with guide pipe in the passage inboard.
After this utility model adopted said structure, by at the inboard guide pipe that connects of passage, liquid flowed out from the molecular film air filter in the time of can preventing that syringe needle from upwards taking out medicine, makes the convenient advantage of use of syringe.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing this utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of specific embodiment of this utility model;
Fig. 2 is a user mode sketch map of the present utility model.
Among the figure: syringe 1, handle 2, sliding sleeve 3, tubular cavity 4, elastic sealing ring 5, sealing plate 6, ventilation pore 7, molecular film air filter 8, guide pipe 9.
The specific embodiment
Consult shown in Figure 1, no push rod medicine adding syringe of the present utility model, comprise syringe 1 and handle 2, be provided with sliding sleeve 3 on syringe 1 top, the outer end of sliding sleeve 3 is inwardly shunk the back and is tightly connected with handle 2, be provided with the tubular cavity 4 that can hold this sliding sleeve 3 with sliding sleeve 3 corresponding syringe 1 barrels, sliding sleeve 3 can slide along this tubular cavity 4; Inner close end at sliding sleeve 3 is provided with elastic sealing ring 5, peristome at syringe 1 is provided with sealing plate 6, sealing plate 6 is provided with ventilation pore 7, be connected with molecular film air filter 8 in ventilation pore 7 outsides, prevent that further pollutant from entering in the syringe 1, to the cross-contamination of medicinal liquid, guarantee drug safety in the time of can preventing operating syringe effectively; Be connected with guide pipe 9 in ventilation pore 7 inboards, can make syringe when extracting medicinal liquid, prevent that medicinal liquid from flowing out from molecular film air filter 8; Usually be provided with indicating graduation at syringe 1, be used to refer to the liquid level in the syringe, observe during convenient the use; Outwards pulling sliding sleeve 3 can form negative pressure in syringe 1, thus aspiration medicinal liquid.
When this utility model specifically uses, consult shown in Figure 2, identical with the common syringe using method, when handle 2 was pulled out outward, sliding sleeve 3 was when the tubular cavity 4 of syringe 1 barrel moves up, in syringe 1, form negative pressuren zone, thereby can medicinal liquid be pumped in the syringe 1 by syringe needle, when with handle 2 during toward interior extruding, sliding sleeve 3 moves down along the tubular cavity 4 of syringe 1 barrel, medicinal liquid in the syringe 1 is formed malleation, thereby medicinal liquid can be extruded; And the medical worker is in when operation, because of the buffer action of the sealing function and the molecular film air filter 8 of sliding sleeve 3, can avoid liquid medicine contamination effectively.
