Abstract
The utility model discloses an automatic resorption anti-pollution dosing injector, which belongs to the field of injector technology. The main points of the technical scheme of the utility model comprises an injection syringe, a piston arranged in the injection syringe and a guide cover board arranged at the rear end part of the injection syringe. A column push rod passes through the middle partof the guide cover board to be connected with the piston, the rear part of the injection syringe is connected with an air filter which is communicated with an inner cavity of the injection syringe, and an elastic pial sleeve whose natural length is shorter than the travel route of the piston in the injection syringe is arranged on the periphery of the column push rod between the guide cover boardand the piston, wherein a locating sleeve extends from the middle part of the guide cover board; and one end of the elastic pial sleeve is fixed on the periphery of the column push rod through a compression lantern ring, and the other end of the elastic pial sleeve is fixed on the periphery of the locating sleeve through another compression lantern ring. The utility model has the advantages of simple processing and convenient assembly, and is used for liquor preparation.
Description
Technical field
This utility model relates to a kind of syringe, and more particularly, it relates to a kind of automatic resorption type antipollution medicine adding syringe of medicinal liquid allotment.
Background technology
Chinese patent ZL200720051360.X (publication number CN201022886Y, open on 02 20th, 2008 day) a kind of " built-in anti-pollution injector " disclosed, by 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, for this reason, (open day: on JIUYUE 17th, 2008 for Chinese patent application ZL20081002775.2, publication number: CN101264359A) disclosed " automatic resorption type antipollution medicine adding syringe " is exactly the improvement that technique scheme is carried out, by the telescopic natural length of elasticity mantle is lacked this technical characterictic than piston at the stroke of syringe, utilize the telescopic resilience force of elasticity mantle to solve medicinal liquid and begin to aspirate inconvenient deficiency.But all do not provide mantle telescopic concrete fixed form in above-mentioned two technical schemes, for this reason, the present inventor provides a kind of preferable embodiment at above-mentioned technical problem.
The utility model content
The technical problems to be solved in the utility model is the above-mentioned deficiency at prior art, and a kind of automatic resorption type antipollution medicine adding syringe simple, easy to assembly of processing is provided.
The technical solution of the utility model is such: a kind of automatic resorption type antipollution medicine adding syringe, comprise 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, be connected with air filter is communicated with the syringe inner chamber at the syringe rear portion, column push rod periphery between defelctor apron and piston is provided with natural length than the short elasticity mantle sleeve pipe of the stroke of piston in syringe, wherein, described defelctor apron middle part is extended with locating sleeve, the telescopic wherein end of elasticity mantle compresses the collar by one and is fixed on column push rod periphery, and the telescopic other end of elasticity mantle compresses the collar by another and is fixed on the locating sleeve periphery.
In above-mentioned a kind of automatic resorption type antipollution medicine adding syringe, be connected for interference fit between described defelctor apron and the syringe.
After this utility model adopts said structure, compress fixedly elasticity mantle sleeve pipe of the collar by two, compress the simple in structure, easy to process of the collar, the combination of medicine adding syringe is also very convenient, and can guarantee to fix and sealing effectiveness.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing this utility model is described in further detail, but portion constitutes 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 the telescopic assembling sketch map of this utility model elasticity mantle;
Fig. 3 is a user mode sketch map of the present utility model.、
Among the figure: syringe 1, piston 2, defelctor apron 3, locating sleeve 3a, column push rod 4, air filter 5, elasticity mantle sleeve pipe 6, compress the collar 7.
The specific embodiment
Consult shown in Figure 1, a kind of automatic resorption type antipollution medicine adding syringe of the present utility model, comprise syringe 1, be arranged on the piston 2 in the syringe 1, the defelctor apron 3 that is provided with in the rearward end of syringe 1, for interference fit is connected, both convenient combination is installed, and can guarantee sealing effectiveness again between defelctor apron 3 and the syringe 1; Column push rod 4 passes these defelctor apron 3 middle parts and is connected with piston 2, be connected with air filter 5 is communicated with syringe 1 inner chamber at syringe 1 rear portion, column push rod 4 peripheries between defelctor apron 3 and piston 2 are provided with natural length than the short elasticity mantle sleeve pipe 6 of the stroke of piston 2 in syringe 1, be extended with locating sleeve 3a at defelctor apron 3 middle parts, the lower end of elasticity mantle sleeve pipe 6 compresses the collar 7 by one and is fixed on column push rod 4 peripheries, and the upper end of elasticity mantle sleeve pipe 6 compresses the collar 7 by another and is fixed on locating sleeve 3a periphery.
Consult shown in Figure 2, when elasticity mantle sleeve pipe 6 of the present utility model makes up with column push rod 4, earlier elasticity mantle sleeve pipe 6 is enclosed within column push rod 4 peripheries, then two plastics are compressed the collar 7 and be enclosed within elasticity mantle sleeve pipe 6 peripheries, the lower end of elasticity mantle sleeve pipe 6 is enclosed within column push rod 4 lower ends than on the big slightly locating ring of column push rod 4 external diameters, will compresses the collar 7 and move down and enforce to the end and can compress sealing to elasticity mantle sleeve pipe 6 lower ends; Same, elasticity mantle sleeve pipe 6 upper ends are enclosed within the locating sleeve 3a periphery that extend at defelctor apron 3 middle parts, another is compressed the collar 7 moves up and is forced into locating sleeve 3a periphery and elasticity mantle sleeve pipe 6 upper ends can be compressed sealing, combination is packed piston 2 into after finishing in the syringe 1 again, and defelctor apron 3 is fastened promptly to assemble in the open rearward end portion of syringe 1 finishes.
When this utility model specifically uses, consult shown in Figure 3, medical personnel can be easily with singlehanded with column push rod 4 to pressing down, thereby driving piston 2 moves down, after loosening, column push rod 4 moves up under the resilience force effect of elasticity mantle sleeve pipe 6, thereby driving piston 2 moves up, realize the auto-pumping medicinal liquid of incipient stage, Chou Xi medicinal liquid is more if desired, medical personnel's reuse hands till having aspirated medicinal liquid, carries out operations such as admixing medical solutions, injection with upwards pulling of column push rod 4 then.Air filter 5 can be realized the air eliminating in the syringe 1 or suck, and prevent that antibacterial, virus etc. from entering in the syringe 1, make more convenient to operately, when the present invention can effectively avoid medical personnel to operate pollutant are entered the cross infection that causes in the syringe 1 by column push rod 4.
