Abstract

The invention discloses a self-control suction-type patient-controlled analgesia device. Besides an oxygen and laughing gas flow controller arranged by doctors, the patient-controlled analgesia device further comprises a self-control button, a self-control device for patients, a flow adjusting device, a data storage device, a serial-port communication module, a clock module, a power source module and a data displayer, wherein air sources of oxygen and laughing gas and the output end of the power source module are communicated with the input end of a quality and flow controller, the output end of the quality and flow controller is connected with the input end of a gas blending device, and the output end of the gas blending device is connected with the input end of a ventilating loop the output end of which is connected with a nasal mask wore by the patient; after the patient feels pain, the patient can switch on the device by pushing the self-control button, when the self-control device for the patients receives a command sent by the patient by pushing the self-control button, a main control module circuit immediately adjusts the open aperture of an oxygen and laughing gas electromagnetic valve in the quality and flow controller through the serial-port communication module. In this way, the oxygen flow is reduced, and meanwhile, the laughing gas flow is increased, so that the patient-controlled analgesia effect is taken.

Description

technical field [0001] The invention relates to a medical device for realizing the analgesic effect of a patient through respiratory inhalation, in particular to a patient-controlled inhalation analgesic method and device in which the concentration of the inhaled drug is adjusted and controlled by the patient. Background technique [0002] It has always been a very important task for medical institutions to eliminate the pain and fear of patients in the implementation of various diagnosis and treatment activities for patients. At present, during the diagnosis and treatment projects implemented by medical institutions such as stomatology, obstetrics and gynecology, gastroenterology, cosmetology and other diagnosis and treatment projects, patients are usually inhaled with nitrous oxide (laughing gas) to achieve painlessness and sedation Effect. With the popularization of the concept of comfortable medical treatment in recent years, there are more and more such demands in clin...
