Description

It ensures the stability of the output anesthetic gas concentration by accurately controlling the evaporation rate of anesthetic drugs. It is mainly used in the process of general anesthesia, and can accurately control the concentration of anesthetic gas, provide a stable anesthetic gas concentration, ensure the consistency of the anesthetic effect, and thus ensure that the patient is at an appropriate depth of anesthesia.

There is a hot steaming component 336, and the top surface of the evaporation tank 335 is penetrated and connected with a first medicine outlet hopper 332 and a second medicine liquid pipe 333. The top end of the first medicine outlet hopper 332 is penetrated and connected to the inside of the air delivery cavity of the medicine outlet box, and the top end of the second medicine liquid pipe 333 is penetrated and connected to the inside of the liquid delivery cavity of the medicine outlet box. The outer wall of the second medicine liquid pipe 333 is provided with a first control valve 334, and the bottom end of the second medicine liquid pipe 333 is penetrated and connected to the inside of the hot steaming component 336.

[0047] The anesthetic is controlled to enter the hot steaming component 336 for evaporation preparation through the second liquid medicine pipe 333, and then the hot steaming component 336 guides the gaseous anesthetic and discharges it into the air delivery cavity of the drug delivery box 311 through the first drug outlet hopper 332, so that the liquid anesthetic and the gaseous anesthetic are processed independently to avoid mutual interference, thereby ensuring the stability of the concentration of the prepared gaseous anesthetic.

[0048] In this embodiment, the hot steaming component 336 includes a second baffle 3361, a first fixed block 3362, an elastic inner heat ring 3363, a second fixed block 3364, a sealing plug 3365, a second medicine outlet hopper 3366, a second control valve 3367, a guide rod 3368 and a spring 3369.

[0058] Then adjust the second control valve 3367 to control the gaseous anesthetic to be discharged upward. The gaseous anesthetic rises and passes through the first drug outlet hopper 332 into the air delivery chamber of the drug delivery box 311. Start the fan 313 to accelerate the flow of the gaseous anesthetic to the transfer column 315. The first detection head 3141 detects the concentration of the gaseous anesthetic and uploads it to the concentration detector 314 for display. After the gaseous anesthetic passes through the through hole 3151 of the transfer column 315, it is discharged from the drug outlet pipe 318, and the second detection head 3142 is used to detect the flow of the gaseous anesthetic. Finally, the quantitative gaseous anesthetic with the required concentration is combined with the carrier gas and delivered to the patient for use.
