Abstract
The utility model provides a compaction and sealing structure for anti-pollution syringe, including the syringe cylinder, piston set inside the syringe cylinder, piston rod connected at the rear part of the piston, push handle set at the external part of the piston rod and elastic protective soft membrane sleeve set at the external of the piston rod. A section of connecting pipe is extended at the external side at the rear part of the syringe cylinder and the internal side of the push handle; the two ends of the protective soft membrane sleeve are covered at the connecting pipes at the external side at the rear part of the syringe cylinder and the internal side of the push handle; glands are set at the external of the two ends for the protective soft membrane sleeve; elastic seal ring is set in between the gland and the protective soft membrane sleeve; the gland and the connecting pipe are joined via screw thread. This utility model, with simple structure and convenient manufacturing, can be best applied for the anti-pollution syringe.
Description
Technical field
This utility model relates to a kind of medical supplies, in particular for the hermetically-sealed construction that compresses 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 that compresses 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 that compresses 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, the handle inboard is extended with one section connection tube respectively, the telescopic two ends of protection mantle are socketed in the back end of syringe outside respectively, on the connection tube of handle inboard, be provided with gland in protection periphery, the telescopic two ends of mantle, between gland and protection mantle sleeve pipe, be provided with elastic seal ring, be threaded between gland and the connection tube.
The leading portion that compresses 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.
After this utility model adopts said structure, the connection tube that utilization is extended on syringe, handle, can be easily the telescopic two ends of protection mantle be connected with handle with syringe, a kind of structure that is tightly connected of simple in structure, easy manufacturing is provided for the production of anti-pollution injector.
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.
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.
The specific embodiment
Consult figure institute, anti-pollution injector of the present utility model compress hermetically-sealed construction, comprise syringe 1, be arranged on the piston 2 in the 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, the two ends of protection mantle sleeve pipe 6 are socketed in the outside, syringe 1 rear end respectively, on the connection tube 5 of handle 4 inboards, periphery, two ends at protection mantle sleeve pipe 6 is provided with gland 7, is provided with elastic seal ring 8 at gland 7 with protecting between the mantle sleeve pipe 6, is threaded between gland 7 and the 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.
