Abstract
The utility model provides a medical one-way valve rubber bottle plug. The bottle plug is made from a regular rubber bottle plug by adding a valve and a through hole to the regular rubber bottle plug, wherein the through hole is a round tube with big end up and the valve provided inside, the valve is closed without the action of external force and can be opened under the action of tension, while after the action is gone the valve is closed automatically. The outer side of the bottle plug can be sealed with plastic. According to the medical one-way valve rubber bottle plug, liquid medicine is prevented from being polluted by rubber particles, and therefore the purpose of safe transfusion is achieved. Meanwhile, the medical one-way valve rubber bottle plug is simple in structure and economical and practical, can be used for bottled liquid and powder as well as bagged liquid and the like, and is wide in clinical application range.
Description
Technical field
The present invention relates to a kind of medical apparatus, specifically a kind of medical unidirectional valve bottle closure of rubber.
Background technology
Present various medical grade rubber plugs all are integrative-structures; need during use could use with syringe needle puncture bottle stopper; because syringe needle is a kind of hollow tubular structures; in the process of puncture bottle stopper, often have rubber particle and stop up syringe needle or pollute medicinal liquid, cause patient's anaphylaxis or infusion reaction.
Summary of the invention
For addressing the above problem, the invention provides a kind of medical unidirectional valve bottle closure of rubber.
The present invention is achieved in that in General Purpose Rubber bottle stopper central authorities increases flap valve, through hole.
Through hole is little at the bottom of being one, head is large, inner pipe with flap valve.
Flap valve is in closed state in the effect that does not have external force, can open when being subject to the tension force effect, again can self-closed after effect disappears, and plastic seal can be used in the bottle stopper outside.
The invention has the beneficial effects as follows: avoid rubber particle to pollute medicinal liquid, reached the purpose of safe infusion, simultaneously simple in structure, economical and practical, not only be used for bottling liquid, powder, also can be used for bag liquid etc., clinical practice is extensive.
Description of drawings
Be described further below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention.
Among the figure 1, bottle stopper, 2, through hole, 3, flap valve.
The specific embodiment
As shown in the figure, central authorities increase flap valve structure (comprising through hole 2 and flap valve 3) at the General Purpose Rubber bottle stopper, through hole 2 is little at the bottom of being one, head is large, inner pipe with flap valve 3, elasticity is moderate, flap valve 3 is in closed state in the effect that does not have external force, can open when being subject to the tension force effect, again can self-closed after effect disappears, aseptic for guaranteeing in addition, bottle stopper 1 outside is good with plastic seal.
After during use the plastics package of bottle stopper 1 outside being removed, only need syringe needle is injected in the through hole 2 of rubber stopper, slightly firmly just flap valve 3 can be strutted, just can be to dosing in the bottle or extraction medicinal liquid, needle tubing is extracted, flap valve 3 pinch confinement.
Claims (3)
1. a medical unidirectional valve bottle closure of rubber is characterized in that, central authorities increase flap valve, through hole at the General Purpose Rubber bottle stopper.
