Abstract
The utility model provides a seal structure for preventing injection pollution and comprises a needle canister, a piston rod connected with the back end of the piston, a pull handle arranged on the outer end of the piston rod; and a flexible protection soft film sleeve arranged around the piston rod; wherein. The outer side at the back end of the needle canister and the inside of the pull handle extends connecting tubes; one end of the protection soft film sleeve is seal connected with one connecting tube; the other end of the protection soft film sleeve is connected with the other connecting tube; a pressing cover is arranged around the protection soft film sleeve; a flexible seal ring is arranged between the pressing cover and the protection soft film sleeve; and the pressing cover is connected with the connecting tube through screw threads. The utility model has the advantages of simple structure and easy manufacturing, and can be used in a sleeve type pollution-proof injector.
Description
Technical field
This utility model relates to a kind of medical supplies, in particular for the hermetically-sealed construction of a kind of anti-pollution injector of intramuscular injection, medicine allocation.
Background technology
At present, the intramuscular injection device that generally uses in the hospital is made up of syringe, piston and piston rod, and medical personnel are to drive piston by the push-and-pull piston rod to move in 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 piston rod, causes liquid medicine contamination easily.For avoiding medical personnel in the pollution of using syringe to medicinal liquid, the way that a lot of people have proposed increase by one protection tube outside piston rod solves the problems of the technologies described above, but concrete being tightly connected to protection tube and syringe and piston rod outer end, really not corresponding concrete scheme is difficult to concrete enforcement.
Summary of the invention
The purpose of this utility model provides a kind of hermetically-sealed construction of a kind of anti-pollution injector simple in structure, easy to manufacture.
The purpose of this utility model is achieved in that a kind of hermetically-sealed construction of anti-pollution injector, comprise syringe, be arranged on the piston in the syringe, be connected the piston rod of piston rear end, be provided with handle in the piston rod outer end, be provided with telescopic protection mantle sleeve pipe in the piston rod periphery, wherein: the described back end of syringe outside, handle inboard are extended with one section connection tube respectively, and the protection telescopic wherein end of mantle and one of them connection tube socket are tightly connected; The protection mantle telescopic other end is socketed on another connection tube, is provided with gland in the telescopic periphery of protection mantle of this end, is provided with elastic seal ring at gland with protecting between the mantle sleeve pipe, is threaded between gland and this section connection tube.
The leading portion of the connection tube described in the hermetically-sealed construction of above-mentioned anti-pollution injector is taper, can conveniently generate to add to protect that mantle is telescopic to be connected and fixed man-hour.
Protection mantle sleeve pipe described in the hermetically-sealed construction of above-mentioned anti-pollution injector and the connection tube socket flexible tight loop of portion's overcoat that is tightly connected.
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 the present utility model.
Among the figure: 1-syringe, 2-piston, 3-piston rod, 4-handle, 5-connection tube, 6-protection mantle sleeve pipe, 7-gland, 8-elastic seal ring, 9-elasticity tight loop.
The specific embodiment
Consult Fig. 1, the hermetically-sealed construction of a kind of anti-pollution injector of the present utility model, comprise syringe 1, be arranged on the piston 2 of syringe 1, be connected the piston rod 3 of piston 2 rear ends, be provided with handle 4 in piston rod 3 outer ends, be provided with telescopic protection mantle sleeve pipe 6 in piston rod 3 peripheries, in the outside, syringe 1 rear end, handle 4 inboards are extended with one section connection tube 5 respectively, a wherein end of protection mantle sleeve pipe 6 and handle 4 inboard connection tube 5 sockets of extending are tightly connected, at protection mantle sleeve pipe 6 and the connection tube 5 sockets flexible tight loop 9 of portion's overcoat that is tightly connected, to strengthen sealing effectiveness; The other end of protection mantle sleeve pipe 6 is socketed on the connection tube 5 that extends in the outside, syringe 1 rear end, periphery at the protection mantle sleeve pipe 6 of this end is provided with gland 7, between gland 7 and protection mantle sleeve pipe 6, be provided with elastic seal ring 8, be threaded between gland 7 and this section connection tube 5; The leading portion of connection tube 5 is taper, connects with convenient.
When this utility model specifically uses, identical with traditional ordinary syringe, because of outside piston rod 3, being provided with telescopic protection mantle sleeve pipe 6, can avoid medical personnel's finger contact piston bar 3 when using syringe effectively, prevent that the medicinal liquid in the syringe 1 is contaminated, guarantee safety, the health of injection, medicinal liquid allotment.
