Abstract
The utility model relates to a safety fitting for automatic protection of intravenous infusion. According to the structure of the safety fitting, an end of an air path channel of a bottle stopper puncture device is communicated with an air inlet. A liquid channel is communicated with infusion pipeline. The liquid channel is communicated with a protecting device and is then communicated with the infusion pipeline. The liquid channel is communicated with a liquid stoppage chamber in the protecting device. A floating block is placed in the liquid stoppage chamber. An outlet stopper at the bottom of the liquid stoppage chamber is provided below the floating block. The outlet stopper is communicated with the infusion pipeline. The safety fitting settles a defect that intravenous blood reflux or severe medical accident caused by entering of air bubbles into body of the patient when infusion injection member is not pulled out in time or bottle change operation is not performed in time and the air enters the infusion pipelines and form air bubbles. The safety fitting for automatic protection of intravenous infusion further has the following functions: directly blocking the infusion pipe after infusion is finished, overcoming an abuse of intravenous blood reflux caused by a fact that the infusion pipe is not pulled out after infusion is finished, causing the patient to rest in the infusion process, requiring no walking inspection of medical personnel, and greatly improving safety in infusion.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of safety fittings for the automatic protection of venous transfusion.
Background technology
Before the present utility model, the disposable gravity liquid infusing type transfusion device that uses is clinically extracted the transfusion injection member or is in time changed the bottle operation as if untimely after transfusion finishes at present, air will enter infusion pipeline and form bubble, bubble enters in patient's 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 increased patient, entourage and medical personnel's stress and work difficulty virtually.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned defective, develops a kind of safety fittings for the automatic protection of venous transfusion.
The technical solution of the utility model 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 major technique is characterised in that fluid passage connection protector is communicated with infusion pipeline again; It is that fluid passage is communicated with the sap cavity that ends in the protector that described fluid passage is communicated with protector, 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 utility model and effect are directly to block tube for transfusion after transfusion finishes, having overcome transfusion finishes and does not extract the drawback that tube for transfusion causes the vein blood back, the patient can feel at ease to have a rest in infusion process, do not need medical personnel's tour of running back and forth yet, increased the safety of transfusion greatly.
This utility model 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
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5:
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 has air filter and stopper; Fluid passage 2 passes the package casing 3-1 in the protector 3, enter and be communicated with and end sap cavity 3-2, place floating block 3-3 in the sap cavity 3-2 and end, end the fixedly connected baffle plate 3-4 of 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 at 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.
The explanation of this utility model application process:
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 medicinal liquid from less to more in the sap cavity 3-2; medicinal liquid liquid makes floating block 3-3 float and leaves 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 not having at last; make that ending the interior floating block 3-3 of sap cavity 3-2 falls after rise gradually, come back to only sap cavity 3-2 inner bottom part at last, 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, makes that air can not be from entering human vein here, thereby guarantees transfusion safety.
