Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of disposable safe transfusion system.
Background technology
Transfusion is named again and is had an intravenous drip or hang water.By the large bolus injection liquid in intravenous drip input body, to supplement body fluid, electrolyte, nutrient substance is provided, inputs effective, the most the most frequently used method of medicine treatment disease.Transfusion completes by means of transfusion device, at present, the transfusion device that medical institutions are used is all by intravenous needle, infusion tube, flow control valve, drip kettle, air filter and bottle plug puncture unit are formed by connecting, medical personnel are when infusing for patient, by be equipped with liquid bottle or bag hang on drip stand after, air enters bottle or the bag that liquid is housed from air inlet pipe, the liquid level that bubble passes, generation air pressure is assembled in space between liquid level and container, under the effect of air pressure, medicinal liquid flows into and drips kettle along thinner infusion tube, when a kettle water column pressure is greater than venous pressure, liquid runs down flexible pipe in bottle or bag flows into vein through intravenous needle.But the function that this transfusion device is not closed automatically, patient needs medical personnel or household to accompany and attend to when transfusion, at medicinal liquid, approach while being totally lost, medical personnel or patient household must stop transfusion as early as possible, otherwise, medicinal liquid can cause backflow of blood or air to enter vein after being totally lost, and has a strong impact on patient's life security.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, automatically closes after providing a kind of transfusion to complete, and guarantees that air does not enter in human body, and blood does not flow backwards, and simple structure, a kind of disposable safe transfusion system easy to use.
In order to reach above object, technical solution adopted in the utility model is: this kind of disposable safe transfusion system consists of intravenous needle, infusion tube, flow regulator, a kettle, air inlet pipe, air filter and bottle plug puncture unit, it is characterized in that: intravenous needle is connected to infusion tube one end, bottle plug puncture unit is connected to the other end of infusion tube, infusion tube is provided with and drips kettle, between a kettle and intravenous needle, is provided with flow regulator; One end of air inlet pipe is connected to the bottom of bottle plug puncture unit, and the other end of air inlet pipe is connected on air filter; Top in dripping kettle is provided with dividing plate, and dividing plate is circular, and the outer of dividing plate is connected on the inwall that drips kettle, the center of dividing plate is provided with liquid-leaking nozzle, below liquid-leaking nozzle, connect short tube, the internal diameter of short tube is identical with the aperture of liquid-leaking nozzle, and egative film is located at the below of short tube, egative film is circular, the diameter of egative film is greater than the external diameter of short tube, and the outer of egative film is arranged with ear, and elastic yarn is located at the outside of short tube, one end of elastic yarn be connected to dividing plate below, the other end of elastic yarn is connected on ear; Due to the pulling force of elastic yarn, egative film is sealed in the lower end of short tube.
When using this utility model, when having drop, medicine enters short tube, and due to the effect of gravity, elastic yarn extends, and drives egative film to leave short tube, and transfusion is normally carried out, and when splashing into short tube without medicinal liquid, elastic yarn is retracted, and drives egative film to be sealed in again the lower end of short tube.
The beneficial effects of the utility model are: this kind of disposable safe transfusion system can automatically be closed after transfusion completes, solve current tube for transfusion used and caused not in time backflow of blood because stopping transfusion, air enters the drawback of vein, and simple in structure, safe and reliable, practical, can be widely used in medical institutions.
