in addition, when being provided with aforementioned temperature sensor 5 in the soft lens body 1, in the rubble operation course of working, through the temperature in the real-time detection cavity of temperature sensor 5, feed back to the temperature tester to judge whether the temperature is too high, when the temperature tester is through the temperature data discovery in the cavity to the feedback surpass the default, can send the warning, remind forbidding or adjusting laser instrument energy output, if adopt the supersound appearance, remind or adjust the energy output of supersound appearance, the unexpected injury to the human body appears when avoiding performing the operation.
When both are included, pressure and temperature can be measured simultaneously, with an alarm if one is out of calibration, or separately.
The system and the using method can monitor the temperature and/or the pressure of the liquid in the cavity, and can sense the temperature (instant, process) and the pressure condition (instant, process) of the environment in the human body cavity at the front end of the soft lens at any time. The temperature of liquid in the cavity can be monitored conveniently by doctors in time during the operation, and unnecessary thermal injury to human body caused by the operation is avoided; meanwhile, the pressure of gas, liquid or gas-liquid mixture in the cavity can be monitored in time during the operation. Avoiding the phenomenon that when the water pressure in the cavity is overlarge, the liquid is reversely flowed to bring the substances containing bacteria, toxin and pyrogen into the blood, causing uropyemia and seriously endangering the life of a patient.
Particularly, in the working process of the lithotripsy operation, the temperature in the cavity is detected in real time through the temperature sensor 5 and fed back to the host of the temperature tester, so that whether the temperature is too high or not is judged. When the temperature data in the cavity fed back by the temperature tester exceeds a preset value, an alarm is sent out to remind the prohibition of energy output of the laser instrument or the ultrasonic instrument, and accidental injury to a human body during operation is avoided.
In the working process of the lithotripsy operation, the pressure in the cavity is detected in real time through the pressure sensor 4 and fed back to the pressure tester, so that whether the pressure is too high or not is judged. When the pressure sensor detects that the pressure in the cavity is greater than a preset value, an alarm is sent to remind that the laser instrument or the ultrasonic instrument is forbidden to output energy. The endoscope flushing and sucking system can also automatically adjust the water supply pressure, and avoid the phenomenon that the substances containing bacteria, toxins and pyrogen are brought into the blood by the liquid backflow caused by the overlarge water pressure, so that the uropyemia is caused, and the life of a patient is seriously threatened.
The above embodiments only show some embodiments of the present invention, which are described in detail and specific, but not to be understood as the limitation of the scope of the present invention, it should be noted that those skilled in the art can make various changes and modifications without departing from the spirit of the present invention, and these embodiments are all within the scope of the present invention. Therefore, the protection scope of the present patent should be subject to the appended claims.
