Embodiment 1

[0028] see figure 1 As shown, an EEG lead of a helmet-type anesthesia depth monitor includes a helmet-type shell 1, and a signal shielding layer 2 is provided in the helmet-type shell, and a layer is arranged in the signal shielding layer to fit the human head. Shaped lining, the position corresponding to the forehead of the human head 3 is provided with an electrode array on the lining, and the electrode array includes a plurality of dry electrodes 4, and the part of each of the dry electrodes protruding from the helmet-like shell is connected to the test line 5 , and then connected with the corresponding monitoring equipment by the test line.

[0029] In this embodiment, a first adjustment knob 7 and a second adjustment knob 8 are also provided on the helmet-shaped shell,

[0030] One end of the first adjustment knob protrudes into the inside of the helmet shell and is drivenly connected to the lining, so that the liner moves back and forth relative to the helmet shell;

Abstract

The invention discloses a head-mounted EEG (electroencephalogram) lead unit for an anesthesia depth monitor. The head-mounted EEG lead unit comprises a head-mounted casing, wherein a signal shielding layer is arranged in the head-mounted casing; a lining fitted with the head shape of a human body is arranged in the signal shielding layer; an electrode array is arranged in the position, corresponding to the forehead of the head of the human body, of the lining and comprises a plurality of dry electrodes, and the part, extending out of the head-mounted casing, of each dry electrode is connected with a testing wire. The head-mounted EEG lead unit for the anesthesia depth monitor has the characteristics of being convenient to use and fast, injection of electrode paste is not needed, and the head-mounted EEG lead unit is not prone to falling off after being worn and has low probability of producing errors, so that monitoring accuracy and reliability are improved.

Description

technical field [0001] The invention relates to an accessory for a medical device, in particular to an EEG lead for a helmet-type anesthesia depth monitor. Background technique [0002] During general anesthesia, maintaining an appropriate depth of anesthesia is very important to ensure patient safety and provide surgical conditions! Therefore, the importance of mastering the monitoring and clinical judgment of the depth of general anesthesia is self-evident. [0003] The traditional judgment of the depth of anesthesia mainly relies on the observation of clinical signs. Including blood pressure and heart rate, pupillary light response, eye movement and tearing, respiratory rate, body movement response, swallowing, saliva secretion, etc. However, these indicators are difficult to accurately and objectively reflect the depth of anesthesia due to their low specificity, many influencing factors, and large individual differences among patients. [0004] EEG bispectral index (B...
