Problems solved by technology

Third, anesthesia is also susceptible to other factors, such as interference from electric knife and poor signal quality. At this time, if there is no good way to eliminate it, it is easy to cause medical accidents
[0011] Moreover, there is also a relationship of interaction and influence between drugs: the three drugs for anesthesia, sedatives, analgesics, and muscle relaxants, after entering the human body, their onset time, action time, and metabolism time are different. The three drugs will interact in the body. Analgesics will affect the effect of sedation. The balance point is quite complicated, which also makes the current anesthesia often cause problems that are too deep or too shallow, which brings unpredictable risks to the surgical process

Embodiment 1

[0115] 1. The target control process of the sedative drug control sub-module is as follows:

[0116] 1. Setting parameters:

[0117] age

[0118] height

[0119] weight

[0120] 2. Find the initial target concentration:

[0121] a. Taking the Chinese as an example, divide the BIS value from 0 to 100 into several intervals according to the table below, and each interval corresponds to a TCI value.

[0122] b. After the induction is completed, open the search window with a window width of 2 minutes. If 20 to 24 BIS values ​​belong to the same interval are found in the window, the TCI value of this interval will be used as the initial target concentration; if there is no BIS value in the first window If 20 to 24 BIS values ​​belonging to the same interval are found, the window moves for 5s to continue the search. When the initial target concentration is determined, the closed-loop control function is turned on.

[0123] 3. Closed loop control

[0124] a. Check the BIS valu...

Embodiment 2

[0160] Clinical Research Data

[0161] A total of 61 cases were screened in this study, 60 cases were randomly enrolled, 30 cases in the manual group and 30 cases in the closed-loop group. There were no cases dropped out or excluded.

[0162] At the time of enrollment, there were no significant differences in gender, age, height, weight, BMI, and ASA classification between the artificial group and the closed-loop group. .

[0163] At the time of enrollment, there was no significant difference between the artificial group and the closed-loop group in terms of cardiopulmonary disease, liver and gallbladder disease, endocrine system disease, diabetes, eye disease and other coexisting diseases.

[0164] There was no significant difference in the type of surgery between the two groups. Among the types of surgery, gastrointestinal surgery was the most (13 cases in the manual group, 14 cases in the closed-loop group), followed by urological surgery (8 cases in the manual group, 6 ...

Abstract

The invention aims at providing an anaesthetic balance control device. The device comprises a data filter module and a drug balance control module. Pre-stored electrocerebral indexes, noxious stimulation data drug usage data are divided into electrocerebral index-sedative data and noxious stimulation data-sedative data. Corresponding drug target control indexes are selected according to electrocerebral index and noxious stimulation data changes in certain period, threshold values are preset, and injection of muscle relaxants are increased or stopped based on the set threshold values. Meanwhile, bispectral index, noxious stimulation data, neuromuscular retarding depth data change tendency slope and the like can be analyzed dynamically, and transverse balance adjusting control is performed on three signals. The invention further provides a work method of the device. According to the device and the method, the problem the imbalanced usage of three drugs is solved, effects of individual differences are prevented, the safety during anesthesia is guaranteed to the largest extent, and good social values and application prospects are provided.

Description

technical field [0001] The invention relates to the field of computers, in particular to an anesthetic drug balance control device and a control method thereof. Background technique [0002] According to clinical statistics, only about 60% of patients can enjoy complete high-quality anesthesia services, about 14% of patients are over-anesthetized, 16% of patients are under-anesthesia, and 10% of patients are in the state of shallow and deep. [0003] If the anesthesia is too light, the patient may have memories of the operation and even feel pain, and in severe cases, it may cause mental or sleep disorders. The "horrible memories" that may be triggered during the operation will become another pain in postoperative life; Sequelae, there may be discomfort for a long time after the operation, and even life-threatening. [0004] Sedation and anesthesia are too deep, and drug overdose will cause slow breathing, until breathing stops, brain hypoxia, and long-term brain hypoxia, c...
