Abstract
The utility model relates to a pollution-free syringe, which is a medical syringe. A medical liquor bottle is arranged in an inner cavity of a needle cylinder shell. The utility model is characterized in that a bidirectional needle head is fixed on a fixed seat of the needle head and assembled at the head part of the needle cylinder shell, a medical liquor port relative to the needle head is sealed by a sealing gasket and an annular outer cap, a rubber plug is arranged at the bottom of the medical liquor bottle, the surface of the rubber plug has a blind hole, a push rod is hollow, and the end head of the push rod is inserted in the blind hole of the rubber plug of the medical liquor bottle. The syringe has the advantages of easy usage and no pollution, and the needle head and the needle cylinder can not fall off at the time of injection.
Description
The pollution-free syringe of this utility model is a kind of injector for medical purpose.
General syringe needs liquid drug separately, and the chance of polluting in the use is more, has caused certain insecurity; Come off sometimes between syringe needle and syringe and make overflow of drug fluid and the damage human body.
The purpose of this utility model is: provide a kind of medicinal liquid bottle to place the inner chamber of syringe shell, syringe needle is two-way pollution-free syringe.
The purpose of this utility model is achieved through the following technical solutions: the medicinal liquid bottle places the inner chamber of syringe shell, and medicinal liquid bottleneck end has seal cover, and rubber stopper is arranged at the bottom, and characteristics are: bidirectional needle is fixed on the syringe needle holder and is assemblied in the syringe case head; Medicinal liquid bottleneck facing to syringe needle is sealed by gasket seal and shaped outer cover, and a rubber stopper is arranged at medicinal liquid bottle bottom, and there is a blind hole rubber stopper outside; Push rod is a hollow form, and the push rod termination is inserted on the medicinal liquid bottle rubber stopper blind hole.Push rod can be taken off when non-working condition, with it as needle cap.When this utility model uses, one end of bidirectional needle passes gasket seal and directly inserts in the medicinal liquid bottle, and when rubber stopper was pushed ahead, medicinal liquid injected human body by the other end of syringe needle, reduce contacting of medicinal liquid and other apparatuses, also reduced the chance of polluting accordingly.This utility model uses back medicinal liquid bottle and syringe needle to go out of use, and the syringe shell can continue to reuse, and need not the strict sterilization sterilization, and can not produce cross infection.
Superiority of the present utility model is: easy to use, pollution-free, syringe needle and sleeve can not come off during injection.
Describe in detail below by embodiment.
The structural representation of accompanying drawing this utility model embodiment.
As figure, this utility model medicinal liquid bottle (1) places the inner chamber of syringe shell (2), and syringe shell (2) can be made of plastic, and bidirectional needle (3) is fixed on syringe needle holder (4) and goes up and be assemblied in syringe shell (2) head; Medicinal liquid bottle (1) mouth is sealed by the foraminous shaped outer cover of gasket seal (5) and center (6), shaped outer cover (6) can be materials such as aluminum, medicinal liquid bottle (1) mouth is facing to syringe needle (3), materials such as medicinal liquid bottle useable glass, medicinal liquid bottle (1) bottom is by rubber stopper (7) sealing, and rubber stopper (7) outer surface has a blind hole (8); The push rod of this utility model (9) is a hollow form, and push rod (9) termination is inserted on the blind hole (8) of rubber stopper (7).
On the said structure basis, syringe shell (2) afterbody socket one sleeve cap (10), a through hole (11) is arranged at sleeve cap (10) bottom, through hole (11) diameter and push rod (9) external diameter are complementary.Materials such as the available plastics of sleeve cap (10), glass, push rod during use (9) is located to be inserted into from the through hole (11) of sleeve cap (10) on the blind hole (8) of rubber stopper, and through hole (11) has guide effect at this, makes push rod (9) propulsive force equilibrium.Sleeve cap (10) has effect dustproof, that overall structure is all claimed at this.
Claims (2)
1, a kind of pollution-free syringe, its medicinal liquid bottle places the inner chamber of syringe shell, and medicinal liquid bottle one end has seal cover, and the other end has rubber stopper, is characterised in that: bidirectional needle is fixed on the syringe needle holder and is assemblied in the syringe case head; Medicinal liquid bottleneck facing to syringe needle is sealed by gasket seal and shaped outer cover, and a rubber stopper is arranged at medicinal liquid bottle bottom, and the rubber stopper outer surface has a blind hole; Push rod is a hollow form, and the push rod termination is inserted on the medicinal liquid bottle rubber stopper blind hole.
