Description

Three-channel infusion set

technical field

The utility model relates to a medical instrument, which is a three-channel infusion set for plastic infusion bottles.

Background technique

At present, intravenous infusion is a commonly used treatment method in clinical practice. The injection medicines used include liquid medicaments and powdered medicaments. The non-inlet infusion set and the two-channel infusion set with air intake tube cannot use the disposable infusion set to export the liquid in the infusion bottle to dissolve the powdered medicine. The dissolution method is to use a syringe to draw liquid from the infusion bottle and inject the powdered medicine. After dissolving, use a syringe to re-inject into the infusion bottle. Some patients should not inject more liquid during intravenous infusion, and also need to use a syringe to extract part of the liquid from the infusion bottle. The disadvantage is: repeatedly puncture the bottle stopper with a syringe It is easy to produce rubber debris to contaminate the liquid medicine. Disposable infusion sets and disposable syringes are packaged and stored separately, which increases the consumption of raw materials and is inconvenient for medical staff to use. At the same time, patients need to pay for disposable infusion sets and disposable syringes at the same time for each infusion. The two costs increase the financial burden on patients.
