Description
Technical field
The present invention relates to a kind of syringe, refer in particular to a kind of automatic resorption type antipollution medicine adding syringe that is used for the medicinal liquid 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 through 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 with harmful substances such as antibacterial bring medicinal liquid into and cause cross infection maybe.Be the liquid medicine contamination of avoiding medical personnel when using syringe, to exist; The scheme that someone has proposed outside push rod, to increase protection tube solves above-mentioned technical problem; But because of complex structure, high, the singlehanded use inconvenience of manufacturing cost are difficult to apply, thereby also do not have a kind of can being applied by effective antipollution syringe so far.Chinese patent ZL200720051360.X (publication number CN201022886Y, open day on 02 20th, 2008) discloses a kind of " built-in anti-pollution injector ", through the column push rod periphery in syringe the mantle sleeve pipe is set; And utilize air filter to be communicated with the syringe inner chamber; Reach the purpose of avoiding cross-contamination, this technical scheme provides comparatively simple technique solution of a kind of structure, but this scheme is in implementation process; Because syringe is when just bringing into use; Comparatively difficult with the hands mobile putter, need to use bigger power just can carry out the medicinal liquid suction, also there is awkward deficiency.
Summary of the invention
But the technical problem that the present invention will solve provide a kind of laborsaving, easy to use, at the automatic resorption type antipollution medicine adding syringe of incipient stage auxiliary suction.
Technical scheme of the present invention is such: a kind of automatic resorption type antipollution medicine adding syringe; Comprise syringe, be arranged on the wing plate of back end of syringe, be arranged on the piston in the syringe; The defelctor apron that is provided with in the rearward end of syringe; The column push rod passes this defelctor apron middle part and is connected with piston, is connected with air filter at the syringe rear portion and is communicated with the syringe inner chamber, wherein; The flexible mantle sleeve pipe of column push rod outer periphery between described defelctor apron and the piston, the telescopic natural length of this elasticity mantle is shorter than the stroke of piston in syringe.
Defelctor apron described in the above-mentioned automatic resorption type antipollution medicine adding syringe is to be extended internally by wing plate to form, and is threaded between wing plate and defelctor apron and the syringe, so not only simple in structure but also conveniently makes processing.
Syringe rear portion described in the above-mentioned automatic resorption type antipollution medicine adding syringe is provided with pipe joint near the wing plate place, and air filter is connected with pipe joint.
The present invention also can be provided with pipe joint on described defelctor apron, air filter is connected with this pipe joint.
After the present invention adopts said structure, owing to adopt elasticity mantle sleeve pipe, and make the telescopic natural length of elasticity mantle shorter than the stroke of piston in syringe; So in use, medical personnel depress push rod with finger, utilize the telescopic resilience force of elasticity mantle to drive piston after loosening and move backward; Realize the auto-pumping medicinal liquid; Firmly bigger inconvenience when having avoided the beginning aspiration medicinal liquid if under the situation of low dose, also can realize auto-pumping; Make things convenient for the medical worker to utilize one hand to aspirate or the liquid medicine injection operation, compared with prior art have advantage laborsaving, that use is convenient.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the present invention is done to specify further, but do not constitute any restriction of the present invention.
Fig. 1 is the structural representation of the specific embodiment of the invention 1;
Fig. 2 is the structural representation of the specific embodiment of the invention 2;
Fig. 3 is the view that the embodiment of the invention 1 push rod is depressed;
Fig. 4 is the push rod view in when suction of loosening of the present invention.
Among the figure: syringe 1, wing plate 1a, defelctor apron 1b, pipe joint 1c, groove 1d, piston 2, column push rod 3, air filter 4, elasticity mantle sleeve pipe 5.
The specific embodiment
Consult shown in Figure 1ly, automatic resorption type antipollution medicine adding syringe of the present invention comprises syringe 1; Be arranged on the wing plate 1a on both sides, syringe 1 rear end, be arranged on the piston 2 in the syringe 1, the column push rod 3 that the lower end is connected with piston 2; The defelctor apron 1b that is provided with in the rearward end of syringe 1; Defelctor apron 1b in the present embodiment is extended internally by wing plate 1a to form, and is threaded between wing plate 1a and defelctor apron 1b and the syringe 1, and the processing combination is convenient like this; Column push rod 3 passes this defelctor apron 1b middle part; Being connected with air filter 4 at syringe 1 rear portion near wing plate 1a place is communicated with syringe 1 inner chamber; Air filter 4 can adopt molecular film filter commonly used in the prior art; This type filter can pass through air, and prevents that macromole such as antibacterial, virus from passing through; The mode that is communicated with is to be provided with pipe joint 1c at syringe 1 rear portion near wing plate 1a place, and air filter 4 is connected with pipe joint 1c; The flexible mantle sleeve pipe 5 of column push rod 3 outer periphery between defelctor apron 1b and piston 2; The natural length of this elasticity mantle sleeve pipe 5 (promptly under the state that does not stress) is shorter than the stroke of piston 2 in syringe 1; After depressing column push rod 3, can utilize the resilience force drive piston 2 of elasticity mantle sleeve pipe 5 to move backward like this, realize the auto-pumping medicinal liquid of incipient stage; Firmly bigger inconvenience when having avoided the beginning aspiration medicinal liquid is used convenient, laborsaving.
Consult shown in Figure 2, another kind of automatic resorption type antipollution medicine adding syringe of the present invention, basic identical with embodiment 1, not existing together is on defelctor apron 1b, to be provided with groove 1d, air filter 4 is installed in this groove 1d, result of use is identical.
Consult Fig. 3, shown in Figure 4, when the present invention specifically uses, medical personnel can be easily with singlehanded with column push rod 3 to pressing down; Move down thereby drive piston 2, after loosening, column push rod 3 moves up under the resilience force effect of elasticity mantle sleeve pipe 5; Thereby driving piston 2 moves up; Realize the auto-pumping medicinal liquid of incipient stage, the medicinal liquid of suction is more if desired, and medical personnel's reuse hands is with upwards pulling of column push rod 3; Till having aspirated medicinal liquid, carry out operations such as admixing medical solutions, injection then.Air filter 4 can be realized the air eliminating in the syringe 1 or suck; And prevent that antibacterial, virus etc. from getting in the syringe 1; Make more convenient to operately, when the present invention can effectively avoid medical personnel to operate pollutant are got into the cross infection that causes in the syringes 1 through column push rod 3.
