Description

An infusion device with high safety and a method for accurately identifying infusion patients

technical field

The invention belongs to the technical field of medical devices, and in particular relates to a highly safe transfusion device and a method for accurately identifying transfusion patients.

Background technique

Infusion is to instill large doses of injection into the body through veins. Injections are usually packaged in glass or plastic infusion bottles or bags without preservatives or bacteriostatic agents. When in use, the drip rate is adjusted through the infusion device, and it enters the vein continuously and steadily to replenish body fluids, electrolytes or provide nutrients. Because of its large dosage and directly into the blood, the infusion process is required to be safe and stable. If there are drug input errors, drug allergies, or excessive infusion speed, etc., it will threaten the life and health of the patient. If the nurse cannot find out and deal with it in time, The consequences could be disastrous.

Nowadays, some large-scale hospitals receive tens of thousands of patients every day, and a large number of patients need infusion in the hospital. Usually, several nurses are there to provide infusion services for a large number of patients. In the case of a heavy workload, nurses may fail to accurately check whether the drug matches the patient due to negligence, resulting in drug input errors. Such medical accidents occur almost every year. Of course, the hospital will carefully check the patient's name and other information before the infusion, but there is still the possibility of infusion errors. For example, patients with the same name are infused at the same time, and some elderly and children may not be able to accurately check the identity information. And checking the information wastes a lot of time, which reduces the efficiency of the hospital in treating patients.
