Real-time anesthesia level monitoring method based on body temperature monitoring

Abstract

The invention relates to a real-time anesthesia level monitoring method based on body temperature monitoring. A plurality of wireless wearable body temperature probes are connected in series to form an H shape and attached to the skin surface of a patient, the body temperature probes on the two sides are attached to the skin on the two sides along midaxillary lines of the patient, the horizontal sections of the body temperature probes and a spinal innervation area are consistent in body surface sign, the position of the anesthesia level is indicated accordingly, the body temperature of the skin surface of the patient is monitored in real time through a mobile intelligent terminal, and the position of the anesthesia level is judged through the body temperature monitoring. The method has theoutstanding advantages of being free of invasiveness, convenient to use, clear, quantitative, precise and real in time; according to the method, through the monitoring and calculating of the body temperature probes at corresponding parts, the metabolism situation of anesthetics in canalis spinalis can be known without follow-up visiting, the fading situation of the anesthesia level of the patientis monitored through the real-time changes of the skin temperature, and abnormity is early found and handled.

Description

technical field [0001] The present invention relates to the technical field of anesthesia monitoring in clinic, in particular to a real-time anesthesia plane monitoring method based on body temperature monitoring. Background technique [0002] Spinal anesthesia is a commonly used clinical anesthesia method. It has the characteristics of clear analgesic effect, good muscle relaxation and fast postoperative recovery. It is widely used in lower abdomen, lower limbs and pelvic floor operations. Intraspinal anesthesia is to inject local anesthetics into the subarachnoid space or epidural space in the spinal canal, and the spinal nerve is blocked to produce anesthesia in the corresponding area innervated by the nerve root. Therefore, definite anesthesia will be produced after spinal anesthesia block. The anesthesia plane refers to the area where skin pain sensation disappears after the anesthesia nerve in the spinal canal is blocked, and its upper and lower boundaries are called ...

AI Technical Summary

Problems solved by technology

[0006] 1. Acupuncture strength is highly subjective, and different strengths of pain stimuli may produce different test results;

[0007] 2. The patient suffers from repeated acupuncture pains. Before the anesthesia level is determined, the anesthesiologist needs to repeatedly stimulate the patient's skin with the needle. When the patient is punctured in an unanesthetized area, the patient will feel pain, which increases the patient's pain and fear;

[0008] 3. Needle punctures can easily lead to skin infection of the patient. If the force is too small, the measurement will not be obvious. If the force is too large, it will inevitably puncture the skin and form a wound, which will bring pain to the patient and leave hidden dangers of infection.

If medical personnel use unclean needles inadvertently, it may cause the spread of viral hepatitis and even blood-borne diseases such as AIDS;

[0009] 4. For patients with language barriers who cannot communicate, it is difficult to use acupuncture to monitor the plane position after anesthesia;

[0010] 5. It is difficult to obtain accurate main statement materials for patients with generalized hyperalgesia

However, the disadvantage of this method is that it requires professional equipment for infrared imaging and data analysis, and the cost is too high. It is limited to research and cannot be used clinically.

In addition, the sensitivity of this technology is not high. The far-infrared thermal imaging camera can receive the infrared radiation emitted by the human body, accurately measure the body surface temperature, and display it in the form of a thermal image. rate is difficult to capture and reflect body temperature changes, which also limits the application

[0012] In addition, the method of measuring the anesthesia plane in the prior art cannot monitor the change of the plane in real time: the anesthesia plane will be produced with the onset of anesthesia drugs, and will also disappear with the metabolism of the anesthesia drugs, and the anesthesia plane will gradually disappear during the operation, but During the operation, it is difficult to accurately judge the disappearance of the anesthesia level in real time, so adding or stopping the use of intraspinal anesthesia is blind, and there is a risk of underuse and overdose of anesthesia

Nerve damage may also be caused by inaccurate judgment of the level of anesthesia
