Description

Blood return monitoring device for injection pipeline

The present invention relates to a monitoring device for drip injection, and more particularly to a monitoring device for monitoring blood return of an injection line.

Peripheral venous indwelling is the most common invasive treatment in hospitals. According to statistics, approximately 80% of inpatients are treated intravenously every day. Intravenous treatment is similar to other invasive medical measures and has potential risks.

Dropping blood back is a problem that often occurs when intravenous drip injection, mainly because the blood pressure in the venous blood vessels is greater than the liquid pressure in the drip, and most of the causes are too low in the drip bottle, or there is a blockage in the drip tube, for example, there is air. Or a blood clot, or a drop of droplets, or a three-way joint may be installed in the wrong direction. When the blood return to the pipeline occurs, as long as the pipeline is smooth, the drip bottle can be taken up. If the drip is not treated, the blood flowing back into the tubing will condense into a blood clot and block the drip line. Once the tubing is unobstructed, the needle must be removed and re-applied. If the dropper does not pass because there is air in the pipeline, you must try to shake the air back into the drip bottle. If a large amount of air enters the vein through the drip line, it may cause pulmonary embolism and endanger the patient's life.

Accordingly, it is an object of the present invention to provide a blood return monitoring device for an injection line that improves at least one of the disadvantages of the prior art.

Therefore, the blood return monitoring device of the novel injection line is suitable for being installed on a drip tube for intravenous injection and defining the injection line.
