Description

An intelligent preoperative continuous infusion device

technical field

The invention provides an intelligent preoperative continuous infusion device, which belongs to the technical field of medical devices.

Background technique

In clinical medicine, although intravenous infusion is widely used, the commonly used infusion tool is still the traditional Murphy infusion set, and manual monitoring is the main method. During infusion, the infusion bottle (bag) needs to be hung on the infusion stand or higher than the puncture site of the patient, and the liquid medicine is injected into the patient by using the potential difference. Manually adjust the pulley on the infusion set to control the infusion rate based on experience. During the infusion process, nurses need to keep patrolling, and the patient or accompanying staff should observe the remaining amount of liquid medicine. When the liquid medicine is about to be infused or the dripping speed is abnormal, the nurse on duty should be notified in time to deal with it. This not only increases the labor intensity of medical staff, resulting in a greatly increased error rate, but also is not conducive to patients' rest, affecting the quality of treatment. If the nurse fails to deal with the situation such as the end of the drug infusion or the blockage of the infusion tube, it may cause blood return or other dangers, causing pain to the patient, and even leading to medical accidents.

For patients with different individual conditions, different infusion purposes and infusion drugs, the required infusion speed is different. For example, most patients need to fast from food and water for 6 to 8 hours while they wait for surgery. And the longer the wait time, the patient's blood volume will decrease with the waiting time. However, after a long period of fasting of food and water, during anesthesia induction, patients often experience post-induction hypotension after real-time anesthesia induction due to insufficient replenishment of the lost blood volume. Preoperative fluid replacement is an important part of perioperative fluid management, which can ensure the patient's blood volume. Therefore, how to provide an efficient and safe preoperative fluid replacement method is a technical problem to be solved by those skilled in the art.
