Abstract
The utility model provides a safe infusion device, relating to a device which medium is input in a human body. A detection funnel in which detection liquid for heat source quality is contained is added between a needle stand for penetrating through a bottle stopper and an observation funnel. The outer end of an air inlet pipe penetrates through the needle stand of the bottle stopper and extends outwards. The inner end of the air inlet pipe is positioned in the detection liquid for heat source quality. When heat source quality exists in medical liquid in a dropping-bottle or in the air, or pathogenic organism enter the detection funnel, the heat source quality or the pathogenic organism can immediately react with the detection liquid for heat source quality to convert the detection liquid for heat source quality into the jelly state. So the air inlet pipe is sealed to lead infusion to automatically stop and infusion safety is ensured.
Description
Safe transfusion system relates to imports intravital apparatus with medium.
Infusion treatment is one of main means of treatment various diseases in the modern medicine field, and transfusion device is an instrument of realizing infusion treatment.The transfusion device that tradition is used comprises fluid-directing needle, the inducing QI pin that inserts the medicinal liquid bottle stopper, observes dropping funnel, catheter, intravenous needle and the transfusion speed controller of transfusion speed.The weak point of this transfusion device is during harmful substance such as airborne thermal source matter and source of disease microorganism can directly enter medicinal liquid in the medicinal liquid bottle along the inducing QI pin in infusion process, these harmful substances are with in the medicinal liquid input patient body, cause infusion reaction and infection, cause suffering to patient.Therefore, the transfusion device of tradition use is unsafe.
The purpose of this utility model is that design a kind ofly can prevent that thermal source matter and source of disease microorganism are input to intravital safe transfusion system.
What this safe transfusion system comprised that inside contains drain tube chamber and airway lumen wears the bottle stopper pin, with wear that the bottle stopper pin is connected as a single entity wear the bottle stopper needle stand, the outer end opening of drain tube chamber and airway lumen is in the needle tip of wearing the bottle stopper pin, the other end is opened on wears the bottle stopper needle stand, be fixed with the short tube that is communicated with the drain tube chamber on the bottle stopper needle stand wearing, be set with dropper on the short tube, the port of export of dropper is arranged in the inner chamber of observing funnel, observe funnel exit end and be plugged with catheter, the pinch roller formula is housed on the catheter drips fast controller, the port of export of catheter is equipped with liquid medicine filter, the port of export of liquid medicine filter is connected to the intravenous needle catheter, the port of export of intravenous needle catheter is connected on the vein needle stand, on the vein needle stand intravenous needle is housed, its construction features is to be fixed with the detection funnel on the bottle stopper needle stand wearing, preceding half section of dropper is arranged in the inner chamber that detects funnel, the thin end that detects funnel is connected as a single entity with an end of observing funnel suit dropper, and be tightly connected with the outer surface of dropper, in the inner chamber that detects funnel, the thermal source quality inspection also is housed surveys liquid and air inlet pipe, it is overhanging that the bottle stopper needle stand is passed in the air inlet pipe outer end, the inner places the thermal source quality inspection to survey liquid.
During use, the sponson that will detect funnel and air inlet pipe earlier with hand flat after, seal the close air inlet mouth of pipe, to wear the bottle stopper pin again penetrates in the medicinal liquid transfusion bottle, loose one's grip moment under negative pressure and action of gravity, having a spot of medicinal liquid to splash into the thermal source quality inspection that detects in the funnel through airway lumen in the medicinal liquid transfusion bottle surveys the liquid, then, under action of gravity, medicinal liquid is through the drain tube chamber, short tube, dropper, observe funnel, catheter, liquid medicine filter, the intravenous needle catheter, intravenous needle flows out, and again intravenous needle is penetrated human vein, simultaneously, air is through air inlet pipe, liquid is surveyed in the thermal source quality inspection, airway lumen enters in the medicinal liquid transfusion bottle, to guarantee proceeding of transfusion.If there is thermal source matter to exist in medicinal liquid or the air, the thermal source quality inspection is surveyed liquid and is reacted with thermal source matter immediately, becomes the jelly state by liquid state, and this jelly state is sealed the port of export of air inlet pipe, has blocked gas circuit, not following of medicinal liquid, and transfusion stops automatically.Survey the liquid filtration, purification owing to enter the air of transfusion medicine bottle through the thermal source quality inspection again, airborne dust and source of disease microorganism are filtered out.Therefore, this transfusion device has prevented that thermal source matter, source of disease microorganism are input in the patient body, have guaranteed transfusion safety.
The embodiment of safe transfusion system is provided by accompanying drawing, and what accompanying drawing provided is the structural representation of safe transfusion system.
In the present embodiment, what safe transfusion system comprised that inside contains drain tube chamber 2 and airway lumen 3 wears bottle stopper pin 1, wear on the plug bottle stopper pin 1 and be set with pin medicated cap 17, with wear that bottle stopper pin 1 is connected as a single entity wear bottle stopper needle stand 4 for covering the formula needle stand, the outer end opening of drain tube chamber 2 and airway lumen 3 is in the needle tip of wearing bottle stopper pin 1, the other end is opened on wears bottle stopper needle stand 4, be fixed with the short tube 5 that is communicated with drain tube chamber 2 on the bottle stopper needle stand 4 wearing, be set with dropper 6 on the short tube 5, the port of export of dropper 6 is arranged in the inner chamber of observing funnel 7, observe funnel exit end and be plugged with catheter 8, the pinch roller formula is housed on the catheter 8 drips fast controller 9, the port of export of catheter 8 is equipped with liquid medicine filter 10, the port of export of liquid medicine filter 10 is connected to intravenous needle catheter 11, the port of export of intravenous needle catheter 11 is connected on the vein needle stand 12, intravenous needle 13 is housed on the vein needle stand 12, be set with pin medicated cap 18 on the intravenous needle 13, detect funnel 14 wearing to be adhesively fixed with on the bottle stopper needle stand 4, preceding half section of dropper 6 is arranged in the inner chamber that detects funnel 14, the thin end that detects funnel 14 is connected as a single entity with an end of observing funnel 7 suit droppers 6, and be tightly connected with the outer surface of dropper 6, in the inner chamber that detects funnel 14, the thermal source quality inspection also is housed surveys liquid 15 and air inlet pipe 16, it is tachypleus amebocyte lysate that liquid 15 is surveyed in the thermal source quality inspection, and it is overhanging that bottle stopper needle stand 4 is passed in air inlet pipe 16 outer ends, the inner places the thermal source quality inspection to survey liquid 15.
