Abstract

The invention belongs to the technical field of medical instruments and discloses a medical breathing machine which comprises an inspiration tube and an expiration tube. A humidifying tank and a firstwater accumulation cup are sequentially arranged on the inspiration tube in a direction from an inlet to an outlet of the inspiration tube, and a second water accumulation cup is arranged on the expiration tube. A water tank is communicated with the humidifying tank through a water control part, the first water accumulation cup and the second water accumulation cup are provided with water outletscontrolled by respective water outlet electromagnets, and water level sensors are arranged in the first water accumulation cup and the second water accumulation cup respectively. A humidity sensor isarranged in the humidifying tank, each water level sensor is electrically connected with the corresponding water outlet electromagnet through a control box, and the humidity sensor is electrically connected with the water control part through the control box. By the medical breathing machine, the problem of burning of the respiratory tract of a patient or back-blowing of accumulated water to thelung of the patient due to less water in the humidifying tank or excessive water in the water accumulation cups of an existing medical breathing machine can be solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical ventilator. Background technique [0002] Medical ventilator is a device that can effectively replace, control or change people's normal physiological breathing, increase lung ventilation, improve respiratory function, reduce respiratory consumption, and save heart reserve. In modern clinical medicine, ventilators have been widely used Respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation occupy a very important position in the field of modern medicine. A medical ventilator includes an inhalation pipeline and an exhalation pipeline, and a humidification tank and a first water storage cup are sequentially arranged on the inhalation pipeline along the direction from the inlet to the outlet of the inhalation pipeline; The second water storage cup; the outlet en...
