Description

Infusion stand with quantitative constant speed alarm function

technical field

The invention relates to the field of medical devices, in particular to an infusion stand with a quantitative and constant speed alarm function.

Background technique

In the daily work of the hospital, intravenous infusion is a commonly used auxiliary medical method in clinical medicine, and the infusion stand is a commonly used medical device used to hang infusion bottles for intravenous infusion of patients. There are several hooks on the top of the rod, which are used to hang the infusion bottle and have no other functions. In reality, at present, the hospital basically adopts the traditional infusion method, relying on manual control and monitoring, and after the patient hangs the infusion bottle Generally, they will be in a state of nothingness, waiting for the liquid in the infusion bottle to be infused. During this period, patients often play mobile phones, chat, read magazines, or sleep and rest to pass this boring time, so they will forget to read The situation of the remaining capacity of the potion in the bottle, so that the potion is hung up without paying attention, and the timing of taking the needle is missed, resulting in the phenomenon of blood returning, and even life-threatening. For children and elderly patients, sometimes only half a bottle is needed for IV drip. In this case, it is generally difficult to do a quantitative dose manually, and it is easy to forget, which eventually leads to a bottle of IV drip directly, and when excessive drug intake may occur There will be sequelae. And the infusion speed is too fast to easily cause the patient's physical discomfort, and even damage the patient's health. There is currently a lack of equipment that can easily monitor the volume and rate of infusion.
