Description
Technical field
This utility model relates to a kind of medical supplies, in particular for a kind of hermetically sealed 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.
Summary of the invention
The purpose of this utility model be to provide a kind of easy to use, can prevent to point a kind of hermetically sealed anti-pollution injector that the contact piston bar pollutes.
The purpose of this utility model is achieved in that a kind of hermetically sealed 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, wherein: described piston rod periphery is provided with protection tube, the handle of the outer end of protection tube and piston rod outer end is tightly connected, be provided with through hole on the handle in protection tube, through hole is provided with the sealing plug, be provided with the tubular cavity that can hold this protection tube with the corresponding syringe barrel of protection tube, protection tube can slide along this tubular cavity; Inner close end at protection tube is provided with elastic sealing ring, is provided with at least one passage in the bottom or the nearly bottom of tubular cavity.
After this utility model adopts said structure, by protection tube is set outside piston rod, and can hold the protection tube tubular cavity outer tube wall setting, form a seal cavity that surrounds piston rod by sealing ring, protection tube, piston, can prevent effectively that medical personnel from pointing when operating syringe directly touches piston rod, avoid causing pollution, guarantee injection safety liquid medicine injection.
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;
Fig. 2 is a user mode sketch map of the present utility model.
Among the figure: 1-syringe, 2-piston, 3-piston rod, 4-handle, 5-protection tube, 6-through hole, 7-sealing plug, 8-tubular cavity, 9-elastic sealing ring, 10-passage.
The specific embodiment
Consult shown in Fig. 1, a kind of hermetically sealed anti-pollution injector of the present utility model, 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 protection tube 5 in piston rod 3 peripheries, the handle 4 of the outer end of protection tube 5 and piston rod 3 outer ends is tightly connected, and is provided with through hole 6 on the handle 4 in protection tube 5, through hole 6 is provided with sealing plug 7, is used for the production combination of syringe; Be provided with the tubular cavity 8 that can hold this protection tube 5 with protection tube 5 corresponding syringe 1 barrels, protection tube 5 can slide along this tubular cavity 8; Inner close end at protection tube 5 is provided with medical silica-gel elastic sealing ring 9, makes protection tube 5 lower ends form the hermetic seal state with syringe 1 barrel, is provided with a passage 10 in the bottom of tubular cavity 8.
The concrete user mode of this utility model is consulted shown in Fig. 1, Fig. 2, identical with the common syringe using method, when handle 4 is pulled out outward, driving piston 2 by piston rod 3 moves up, thereby can aspiration medicinal liquid, the protection tube 5 of piston rod 3 peripheries also stretches out after the tubular cavity 8 of syringe 1 barrel slides simultaneously; When handle 4 during toward interior extruding, is driven pistons 2 by piston rod 3 and moves down, thereby medicinal liquid can be extruded, the protection tube 5 of piston rod 3 peripheries is also withdrawn along the tubular cavity 8 of the syringe 1 barrel back of sliding simultaneously; Because of protection tube 5 is positioned at piston rod 3 peripheries all the time, piston rod 3 is hidden in the protection tube 5, the medical worker is when operation; Finger can directly not touch piston rod 3, can avoid liquid medicine contamination effectively.
