Description

Technical Field

[0001] The invention relates to the technical field of medical monitoring, in particular to a computer-controlled anesthetic injection system for maxillofacial surgery. Background Art

[0002] Maxillofacial surgery is a surgical treatment for diseases of the face, oral cavity, temporomandibular joint, maxillofacial bones, and salivary glands. Before surgery, patients need to undergo routine examinations, including blood tests, urine tests, chest X-rays, electrocardiograms, and other routine health examinations to assess their health status. Based on the type of surgery and the patient's health status, the medical staff will have an anesthesiologist conduct an anesthesia assessment, develop an appropriate anesthesia plan, and use a syringe pump to perform the push of anesthetic drugs. The syringe pump is an important instrument used to accurately control the speed and dosage of anesthetic drug push to ensure the stability and safety of the patient's anesthesia during surgery. During the operation, the anesthesiologist will continuously monitor the patient's vital signs and adjust the depth of anesthesia and drug dosage as needed.

[0003] At present, the computer-controlled anesthetic injection system used in traditional maxillofacial surgery tends to ignore the patient's basal metabolic rate. The desired anesthesia depth is far from the actual anesthesia effect, resulting in a high anesthesia failure rate. The anesthesia effect cannot be maintained until the end of the operation. In addition, it can only calculate the anesthetic dosage required for the patient in the initial stage of the operation. As the operation progresses, the anesthetic injection plan cannot be automatically adjusted according to the patient's real-time physiological parameters. The anesthesia is not timely and effective, and the patient feels strong pain. Summary of the invention
