Description

A kind of contamination seal syringe

Technical field

This utility model relates to injector for medical purpose, especially a kind of contamination seal syringe.

Background technology

At present, the intramuscular injection device that generally uses in the hospital 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, injection.But find that in actual use medical personnel are when carrying out operation such as aspiration medicinal liquid, admixing medical solutions, injection, finger can touch push rod, exist medicinal liquid contaminated may and cause cross infection.For avoiding medical personnel's pollution to medicinal liquid when using syringe, someone has proposed to increase the scheme of protection tube outside push rod, solve above-mentioned technical problem, but because of complex structure, manufacturing cost height are difficult to apply, thereby also do not have a kind of can being applied by effective antipollution syringe so far.

Summary of the invention

The purpose of this utility model provides a kind of contamination seal syringe of a kind of processing simple in structure, easy, low cost of manufacture.

The purpose of this utility model is achieved in that a kind of contamination seal syringe, comprise syringe, be arranged on the wing plate on back end of syringe both sides, be arranged on piston and the push rod that is connected with piston in the syringe, wherein: described back end of syringe is connected with the mantle sleeve pipe of outer end sealing, and the mantle sleeve pipe is connected on the wing plate of back end of syringe by connector.

Connector described in above-mentioned a kind of contamination seal syringe is made up of inner sleeve and trocar sheath, outer wall at inner sleeve is provided with at least one circle groove, be provided with the bulge loop corresponding with groove at outer sleeve inner wall, the mantle sleeve pipe is fixed between the inside and outside sleeve pipe by bulge loop and groove snapping.

Be respectively equipped with at least one snapping hole on the wing plate on back end of syringe both sides described in above-mentioned a kind of contamination seal syringe, be provided with connecting plate, on connecting plate, be provided with the connection button corresponding with the snapping hole at the wherein end of inner sleeve.

Button described in above-mentioned a kind of contamination seal syringe is to be made of for three sections outer section, stage casing, inner segment, is interference fit between outer section of button and the snapping hole wherein, the stage casing be outer little in big left-hand thread section, inner segment and snapping hole are movingly; Like this can be earlier outer section be connected with the snapping hole, be used for the antiseptic hygiene processing after the combinations of syringe, again the stage casing be snapped onto on the snapping hole during use.

Between connecting plate and wing plate, be provided with sealing gasket described in above-mentioned a kind of contamination seal syringe; To strengthen sealing effectiveness.

The telescopic opening of mantle is provided with reinforcing ring described in above-mentioned a kind of contamination seal syringe; Deviate from from connector to prevent the mantle sleeve pipe.

After this utility model adopted said structure, the protection tube that one outer end is sealed by connector was connected on the wing plate of back end of syringe the handling ease of each accessory, with low cost, and the syringe sterilization after the combination is easy to use easily, and the popularization of anti-pollution injector is had positive effect.

The specific embodiment

Consult Fig. 1 to shown in Figure 5, a kind of contamination seal syringe of the present utility model, comprise syringe 1, be arranged on the wing plate 11 on both sides, syringe 1 rear end, be arranged on piston 2 and the push rod 3 that is connected with piston 2 in the syringe 1, be connected with the mantle sleeve pipe 4 of outer end sealing in syringe 1 rear end, mantle sleeve pipe 4 is connected on the wing plate 11 of syringe 1 rear end by connector 5; This connector 5 is made up of inner sleeve 51 and trocar sheath 52, outer wall at inner sleeve 51 is provided with a circle groove 51a, be provided with the bulge loop 52a corresponding with groove 51a at trocar sheath 52 inwalls, mantle sleeve pipe 4 is fixed between the inside and outside

sleeve pipe

51,52 by bulge loop 52a and groove 51a snapping; On the wing plate 11 on both sides, syringe 1 rear end, be respectively equipped with two spaced snapping hole 11a, be provided with connecting plate 51b, on connecting plate 51b, be provided with corresponding with snapping hole 11a four and connect button 51c at the wherein end of inner sleeve 51; Button 51c is made of for three sections outer section, stage casing, inner segment, is interference fit between outer section of button 51c and the snapping hole 11a wherein, the stage casing be outer little in big left-hand thread section, inner segment and snapping hole 11a are movingly; Like this can be earlier outer section be connected with snapping hole 11a, be used for the antiseptic hygiene processing after the combinations of syringe, again the stage casing be snapped onto on the 11a of snapping hole during use; Between connecting plate 51b and wing plate 11, sealing gasket 6 is set, to strengthen sealing effectiveness; Reinforcing ring 41a can also be set at the opening of mantle sleeve pipe 4, and mantle sleeve pipe 4 is deviate from from connector 5 when preventing that syringe from using, and increases the steadiness that connects.
