Abstract
The utility model relates to an inner capsule-style syringe, belonging to the category of medical appliances. The syringe is composed of a needle cylinder (1), a piston (2) and a needle head (4). The utility model is characterized in that an internal capsule (5) is sheathed in the needle head (4) which is inserted in the joint (3) of the needle cylinder. When the utility model is used, the piston (2) is pumped back along the direction shown by an arrow (6), and the internal capsule (5) is inhaled in the needle cylinder (1). When the piston (2) is pushed along the opposite direction shown by the arrow, physic liquor is injected out. The utility model has the same performance and use method to the performance and use method of the existing disposable syringes, but has low cost.
Description
This utility model relates to the category of medical apparatus and instruments, particularly the syringe of inside bag type structure.
Original syringe is made up of syringe, piston, syringe needle, and is all contaminated after once using, and just cross infection may take place if reuse.
Be head it off, all promote the use of disposable syringe in recent years both at home and abroad.The structure of this syringe is identical with original syringe, though it is lower to manufacture cost with plastics, can prevent cross infection again, and all discarded through once using, consumption is very big.The insufficient area of health resources is difficult to bear its expense.So many medical institutions fail to promote disposable syringe so far.
This utility model is that a kind of improved inside bag type syringe will be provided, and it can prevent cross infection effectively, and cost is very low again.
The purpose of this utility model is achieved in that in syringe needle suit a capsula interna of manufacturing with the strong material of retractility (as latex etc.), and syringe needle inserts the joint area of syringe.When the pumpback piston capsula interna is sucked in the syringe, produce negative pressure in the syringe and make the swollen expansion of rising of capsula interna, medicinal liquid sucks capsula interna.When piston forward promotes, injecting liquid drug is gone out.Syringe needle, capsula interna contact medicinal liquid reach the purpose that prevents cross infection as disposable use, and syringe does not contact medicinal liquid with piston, can reuse, and can reduce cost significantly.
This utility model is because only need the joint of original syringe is enlarged, and is convenient to suit and the syringe needle of capsula interna and insert in the joint of syringe.Because manufacture technology is simple, performance is identical with original syringe with using method, so realize easily.
The concrete structure of utility model is provided by following example and accompanying drawing thereof.
Fig. 1 is the profile according to the inside bag type syringe static state that the utility model proposes; Fig. 2 is dynamic profile.
Describe details and working condition in detail below in conjunction with Fig. 1 and Fig. 2 according to the concrete structure that the utility model proposes.
The inside bag type syringe comprises a syringe (1), is piston (2) in the syringe, inserts a syringe needle (4) in the joint of syringe (3), and suit a capsula interna (5) in the syringe needle.
Fig. 2 is along direction pumpback piston (2) shown in the arrow (6), the capsula interna (5) of syringe needle (4) lining is sucked in the syringe (1), the negative pressure that produces in the syringe makes the swollen expansion of rising of capsula interna, medicinal liquid can be sucked capsula interna (5) lining during use, during along arrow rightabout promotion piston (2), just medicinal liquid can be injected away through syringe needle (4).
Claims (2)
1, injector for medical purpose, particularly inside bag type syringe have piston (2) and syringe (1), have located a syringe needle (4) at the joint (3) of syringe, it is characterized in that the interior suit of syringe needle (4) a capsula interna (5).
2, inside bag type syringe according to claim 1 is characterized in that syringe needle (4) inserts in the joint (3) of syringe.
