Abstract
The invention relates to a safety component for automatic protection in intravenous infusion. The safety component is structured in such a manner: an air inlet is communicated with the tail end of an air channel of a bottle stopper puncture device; a liquid channel is communicated with an infusion pipeline; the liquid channel is communicated with a protecting device and then is communicated with the infusion pipeline; the liquid channel is communicated with a liquid stopping cavity in the protecting device; a floating block is placed in the liquid stopping cavity; and an output stopper at the bottom part of the liquid stopping cavity is placed below the floating block and communicated with the infusion pipeline. By adopting the safety component, the defect that the air flows into the infusion pipeline to generate bubble if an infusion injecting component is failed to be pulled out timely or an infusion bottle cannot be timely changed after the infusion, and the bubble flows into a patient to result in blood flowing in the pipeline from the vein or even cause a serious medical incident, can be solved. Through the safety component, an infusion tube can be directly blocked after the infusion, so that the drawback that the blood flowing in the infusion tube from vein if the infusion tube is not pulled out after the infusion can be overcome, a patient can rest well during infusion, the medical staff is not needed to make an inspection tour repeatedly, and the safety in infusion can be greatly improved.
Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of safety fittings for the automatic protection of venous transfusion.
Background technology
Before the present invention, extract the transfusion injection member or in time change the bottle operation if the disposable gravity infusion formula transfusion device that uses clinically at present is untimely behind infusion-completed, air will enter infusion pipeline and form bubble, bubble enters in the patient body can cause the vein blood back, even causes serious malpractice.This just requires patient, entourage to keep clear-headed in infusion process, and requires medical personnel's repeat runs in-motion viewing to examine, and has virtually increased patient, entourage and medical personnel's stress and work difficulty.
Summary of the invention
Purpose of the present invention just is to overcome defects, develops a kind of safety fittings for the automatic protection of venous transfusion.
Technical scheme of the present invention is:
A kind of safety fittings for the automatic protection of venous transfusion, the terminal air inlet that is communicated with of bottle plug puncture unit gas channels, fluid passage is communicated with infusion pipeline, and its technical characteristics is that fluid passage connective protection device is communicated with infusion pipeline again; Described fluid passage connective protection device is the sap cavity that ends in the fluid passage connective protection device, ends and places floating block in the sap cavity, and the floating block below is the spout plug that ends the sap cavity bottom, and spout plug is communicated with infusion pipeline.
Advantage of the present invention and effect are directly to block tube for transfusion behind infusion-completed, overcome infusion-completed and do not extracted the drawback that tube for transfusion causes the vein blood back, the patient can feel at ease to have a rest in infusion process, does not also need medical personnel's tours of running back and forth, has greatly increased the safety of infusing.
The present invention is simple in structure, and cost increases limited, and function-stable is effective, can be widely used in medical clinic.

Each label represents that the corresponding component title is as follows among the figure:
Bottle plug puncture unit 1, fluid passage 2, protector 3, package casing 3-1, end sap cavity 3-2, floating block 3-3, baffle plate 3-4, liquid-leaking nozzle 3-4-1, spout plug 3-5, infusion pipeline 4, air inlet 5.
The specific embodiment
Such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4:
Two passages are arranged in the bottle plug puncture unit 1, and one is fluid passage 2, and another is gas channels; The terminal air inlet 5 that is communicated with of gas channels, air inlet 5 is with air filter and stopper; Fluid passage 2 passes the package casing 3-1 in the protector 3, enter and be communicated with only sap cavity 3-2, place floating block 3-3 in the sap cavity 3-2 and end, be fixedly connected with baffle plate 3-4 ending sap cavity 3-2, a plurality of liquid-leaking nozzle 3-4-1 are set on the baffle plate 3-4, and baffle plate 3-4 is above floating block 3-3; In the middle of ending sap cavity 3-2 bottom a spout plug 3-5 is set, floating block 3-3 bottom is for spout plug 3-5 top, and floating block 3-3 bottom is semicircular arc, is complementary with spout plug 3-5 top semicircular arc, ends sap cavity 3-2 and is communicated with infusion pipeline 4 by spout plug 3-5.
Application process explanation of the present invention:
As shown in Figure 1:
After the present invention inserts infusion bottle; under the effect of atmospheric pressure; the infusion bottle inner liquid medicine flows into infusion pipeline 4 and forms hydrostatic pressing; when hydrostatic pressing during greater than venous pressure; medicinal liquid is communicated to ending among the sap cavity 3-2 in the protector 3 by the fluid path 2 in the bottle plug puncture unit 1; make only by the liquid-leaking nozzle 3-4-1 on the baffle plate 3-4 and to be full of from less to more medicinal liquid in the sap cavity 3-2; medicinal liquid liquid is so that floating block 3-3 come-up and leave spout plug 3-5; baffle plate 3-4 blocks floating block 3-3 and continues come-up, ends sap cavity 3-2 and is communicated with infusion pipeline 4 to human vein through spout plug 3-5.
As shown in Figure 2:
When the medicinal liquid in the infusion bottle is totally lost; the medicinal liquid that ends in the sap cavity 3-2 in the protector 3 reduces gradually; until do not have at last; floating block 3-3 falls after rise gradually in the sap cavity 3-2 so that end, and comes back at last only sap cavity 3-2 inner bottom part, and the circular arc of floating block 3-3 bottom is just in time agreed with the circular arc on spout plug 3-5 top; and spout plug 3-5 stopped up; whole infusion pipeline 4 is obstructed, so that air can not be from entering human vein here, thereby guarantees infusion safety.
