Adjustable ICU auxiliary breathing device

Abstract

The invention provides an adjustable ICU auxiliary breathing device, and relates to the technical field of medical instruments. The adjustable ICU auxiliary breathing device comprises a support frame;the top end of the support frame is fixedly provided with a control panel; the front end of the control panel is fixedly connected with an air tube; the end, away from the control panel, of the air tube is fixedly connected with a transition tank; the other end of the transition tank communicates with a respirator; and an upper connecting base and a lower connecting base are fixedly installed atthe upper end and the lower end of the transition tank respectively. The adjustable ICU auxiliary breathing device realizes adjustment of the tidal volume by controlling the speed of a motor, is highin adjusting precision and high in response speed, improves the comfort of a patient, can automatically relieve pressure to avoid air pressure injury caused by overlarge tidal volume, and can stir internal air to avoid uneven distribution of air inhaled by the patient and avoid the phenomenon of dyspnea of the patient when a ventilator is abnormally stopped.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable ICU breathing aid device. Background technique [0002] When first aiding or treating patients in the ICU ward, assisted breathing devices, that is, ventilators, are often used. In modern clinical medicine, it has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. [0003] The control of the tidal volume during the use of the ventilator is very important, while the traditional ventilator uses electrical signals to adjust the range of the tidal volume through the control panel, the adjustment accuracy is low and the response time is slow. The comfort of the patient is reduced, and the improper application of mechanical ventilation is prone to occur during the adjustment process, which will cause barotrauma and damage the patient'...

Problems solved by technology

[0003] The control of the tidal volume during the use of the ventilator is very important, while the traditional ventilator uses electrical signals to adjust the range of the tidal volume through the control panel, the adjustment accuracy is low and the response time is slow. The comfort of the patient is reduced, and the improper application of mechanical ventilation is prone to occur during the adjustment process, which will cause barotrauma and damage the patient's body. In order to ensure the assisted breathing effect of the ventilator, the breathing mask of the ventilator It should be attached to the patient's face to avoid the interference of external gas, but if the ventilator fails or the power is cut off, if the patient is in a coma and cannot pull out the breathing mask autonomously, it will easily cause the patient's breathing difficulties. Even suffocation, and when the ventilator operates at a large tidal volume, the inhaled gas is unevenly distributed. In the lung area with good compliance, the gas distribution is more, resulting in excessive expansion of the alveoli without obvious lesions, resulting in an increase in physiological dead space.
