Abstract
The utility model relates to a disposable injector for medical purposes which is composed of a needle, a casing tube, a connecting embolism, a stop cock, and a rubber sealing plug. After injection, the stop cock can be taken out for repeated use, the cross infection generated by the injector during the injection can be strictly prevented. Compared with an existing disposable injector, the raw materials can be saved by more than 20%, and the manufacture cost is lowered.
Description
The present invention relates to a kind of medical plug formula disposable syringe.
Known disposable syringe is to be raw material with silicone rubber, is made up of syringe needle, sleeve pipe, rubber seal plug, embolus.Because it is embolus directly contacts with liquid medicine injection with sleeve pipe, therefore, behind the injector to inject, promptly discarded.
Purpose of the present invention is to prevent to produce under the prerequisite of cross infection by syringe in assurance, designs the medical plug formula disposable syringe that a kind of plug can use repeatedly.
Technical solution of the present invention is: medical plug formula syringe is made up of syringe needle, sleeve pipe, rubber seal plug, connection bolt, plug.Connecting bolt is hollow garden cylindricality, and head is equipped with rubber seal plug, and rectangle or irregularly-shaped hole are arranged at the bottom, are contained in the sleeve pipe.Plug is a solid garden cylindricality, and there are rectangle or special-shaped protruding key in the front portion, inserts to connect bolt bottom rectangle or irregularly-shaped hole internal rotation one angle, promptly combines as a whole, and pushes away or pumpback before the rubber seal plug of promotion connection bolt head carries out in sleeve pipe.Connecting bolt and plug usable resins, silicone rubber, metal, glass etc. makes.
Medical plug formula disposable syringe is that the embolus with known disposable syringe is divided into two sections, and one is truncated into the connection bolt; One is truncated into plug.Because plug does not contact sleeve pipe and medicinal liquid in connecting bolt, thereby guarantee plug in use, when having avoided the human injection fully, the cross infection that medicinal liquid and human body pathogenic bacteria are produced.After syringe used, plug screwed out and connects bolt, can recycle, and saves material more than 20% than former syringe, and manufacturing cost reduces, and can obtain remarkable economic efficiency.
Routine accompanying drawing has been described one embodiment of the present of invention down:
Fig. 1 has described the syringe of being made up of syringe needle 4, sleeve pipe 1, rubber seal plug 5, connection bolt 2, plug 3.Rubber seal plug 5 is contained in and connects bolt 2 heads, connects bolt 2 bottoms and has rectangle or irregularly-shaped hole 7, connects bolt and is contained in the sleeve pipe 1.There are rectangle or special-shaped protruding key 6 in plug 3 front portions, and protruding key 6 inserts rectangle or the irregularly-shaped hole 7 that connects bolt 2 bottoms, rotates an angle plug and promptly fixes with connecting bolt, promote then to push away or pumpback before rubber seal plug is done.
Claims (2)
1, a kind of medical plug formula disposable syringe is made up of syringe needle, sleeve pipe, embolus, rubber seal plug.It is characterized in that: connect bolt 2 bottoms and have rectangle or irregularly-shaped hole 7, there are rectangle or special-shaped protruding key 6 in plug 3 front portions, plug 3 forward rectangles or special-shaped protruding key 6 inserts in the rectangle or irregularly-shaped hole 7 that connects bolts 2 bottoms, rotates an angle, promptly with connect bolt 2 and be fixed as one.
2, syringe according to claim 1 is characterized in that: connection bolt 2, plug 3 can adopt material such as resin, silicone rubber, metal, glass.
