Abstract

The invention provides a medical intelligent ventilator comprising an expiration loop and an inspiration loop, which are connected with a breathing mask; the inspiration loop comprises an intelligent air-oxygen mixer, a bacterium filter, an inspiration valve, an inspiration flow meter, a pressure sensor A, a humidifying device and a heater, which are connected successively, the pressure sensor A being installed at the tail end of the inspiration loop. The expiration loop comprises a check valve, an expiration flow meter, a novel expiration valve and a water-removing bottle, which are connected successively. The breathing mask is internally provided with a carbon dioxide concentration sensor. The carbon dioxide concentration sensor, the pressure sensor A, the intelligent air-oxygen mixer, the inspiration flow meter and the expiration flow meter are connected with an ARM processor. The ARM processor is connected with an LED touch screen and an alarm. The medical intelligent ventilator can work according to the autonomous respiration of a patient, can maintain positive end-expiratory pressure of a patient, can discharge gas exhaled by a patient, is safer and can give alarm automatically.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a medical intelligent ventilator. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. [0003] Effective monitoring of patients with ventilators and automatic alarms for ventilator failures can prevent patients from suffocating when ventilators fail, and intelligent ventilators can provide patients with independent breathing methods instead of fixed ones. frequency. The e...
