Description
Technical Field
The embodiment of the invention relates to the technical field of medical equipment, in particular to a sensor connecting device.
Background
Anesthesia is an indispensable step in surgical operations, and proper anesthesia depth is an important link for ensuring the quality of clinical anesthesia. The side effect of the anesthetic can be reduced as much as possible by avoiding the over-deep anesthesia, and the postoperative recovery is accelerated; avoid anesthesia too shallow can prevent to know in the art, improve patient's comfort level etc.. The electroencephalogram is a main signal of cerebral cortex activity, has the characteristics of reflecting the advantages of consciousness activity, being noninvasive and the like, is in the leading position in anesthesia depth monitoring research at present, and forms an industry consensus that the electroencephalogram consciousness monitoring improves the accuracy of anesthesia, reduces the use of anesthetic, reduces the anesthesia risk and reduces the prognosis complications of operation patients in the operation anesthesia process at present. Therefore, it is very important to judge the depth of anesthesia through electroencephalogram signal acquisition and processing.
The anesthesia depth monitor is characterized in that electroencephalogram signals are obtained by a sensor adhered to the head, a sensor interface is connected with a host, the sensor is locked by a mechanical structure of an interface connecting device, and the sensor is connected with an internal circuit contact of the interface. The electroencephalogram signals acquired by the sensor are transmitted to the host computer, algorithm processing and displaying are carried out, and corresponding monitoring data are provided for doctors. Change the position in the use, mobile device, drag the lead wire, the doctor plug does not press release button etc. easily arouses that sensor and connecting device pine takes off or damage and lead to signal transmission to appear unusually, because of dragging or not pressing release button to pull out when the doctor changes the sensor and insert the sensor and lead to the condition such as interface deformation easily simultaneously, lead to signal interruption or transmission unstable even the interface damage unable use to influence monitoring data's accuracy. Therefore, reliability, stability, and ease of use of the sensor interface connection are important.
When the sensor works, the sensor needs to be inserted into the connecting device, then the sensor is locked into the connecting device through the downward elastic pressure of the locking copper sheet and the locking part of the copper sheet to be in contact with the transmission cable, and therefore signals are transmitted to the host through the transmission conducting wires. When the sensor needs to be taken out or replaced, the release button needs to be pressed down, so that the locking part is lifted up to release the locking part to take out the sensor. In order to prevent the sensor from loosening, the angle and elasticity of the locking copper sheet and the locking part of the elastic sheet need to be adjusted. The traditional interface usually makes the sensor reach the locking state through the angle of adjusting locking copper sheet and shell fragment locking position, the pressure through the locking copper sheet and the angle at shell fragment locking position, in order to take out and change the sensor, need press the release button.
However, in clinical use of such devices, the connection reliability of the sensor has a great influence on the signal connection and transmission stability. In actual use, locking mechanism's deformation, sensor locking can not live or the locking is not in place, and the sensor can't lock to contact with transmission cable in the interface, can lead to the transmission of signal and stability to be influenced greatly. In addition, when a doctor uses the locking copper sheet deformation sensor, the doctor often neglects to press the release button, and the locking copper sheet deformation sensor cannot be pulled out due to the fact that the sensor is plugged and pulled out forcefully, so that the use convenience is greatly limited.
In order to achieve reliable connection and stable signal transmission, the connection form of the locking mechanism and the release button must be changed, so that a more reliable connection transmission form can be provided.
