バッグへの注入という二度手間を要していた。Infusions used for IVH are usually mixed with various vitamins, trace metals, high-concentration salt solutions, etc., which patients tend to lack. High-calorie infusions do not normally contain salt, so mixed saline injections may require excessive salt intake, especially in hypertensive patients. is there. Therefore, in the case of mixed injection of saline solution, it is necessary to determine an accurate mixed injection amount according to the patient's condition. The amount of the saline solution to be mixed and injected is generally 20 to 100 cc, and conventionally, the mixed injection operation is performed by inhaling the saline solution into a syringe and then injecting the saline solution into an infusion bag. Therefore, it is necessary to perform the mixed injection operation on a clean bench or the like in order to prevent contamination by bacteria and the like, and it takes two steps of inhaling a saline solution with a syringe and injecting it into an infusion bag.
