Movable first-aid breathing machine

Abstract

The invention relates to a movable first-aid breathing machine which comprises a movable suite, a material supporting frame, a breathing machine, a breathing guide pipe and a guide pipe frame. The material supporting frame is installed on the movable suite, the breathing machine is fixedly installed on the material supporting frame, the breathing guide pipe is connected to the breathing machine, and the guide pipe frame is installed on the breathing machine. The breathing machine can solve the following problems when an existing breathing machine is used: a, in order to facilitate movement of the existing breathing machine, rollers are often required to be mounted at the lower end of the breathing machine, so that the breathing machine is often moved due to external force interference during use, the breathing machine is further separated from a breathing catheter, and great potential safety hazards exist; and b, when an existing breathing machine carries out gas transmission treatment, a breathing catheter is usually and freely placed and then is tripped to a human body, so that the breathing catheter and the breathing machine are separated, and certain potential safety hazards exist.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a movable emergency 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.

[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. Its working principle is that oxygen enters the gas circuit box, and after passing through the filter, an electric contact pressure gauge is used to monitor the gas source pressure. When the gas source pressure drops to the set alarm When the pressure is high, the circuit alarms, and the oxygen passes through the pressure reducing valve to limit the pressure to 0.28MPa, and then the oxygen passes through the solenoid valve and reaches the tidal volume regulating valve. By adjusting the tidal volume regulating valve, the air flow to the patient can be controlled and the tidal volume can The high-speed gas of the regulating valve generates a negative pressure at the inlet of the air-oxygen mixer, bringing in a certain proportion of air, and the air-oxygen mixed gas enters the airway. For safety, a safety valve is designed in the airway. The safety valve is used To limit the maximum pressure of the patient's airway, it is generally set to 6kPa. When the airway pressure exceeds the safety pressure of the airway system, the safety valve is opened to deflate, and the airflow passes through the inspiratory flow sensor and is converted into a monitoring signal for the system, which can be monitored Inspiratory tidal volume and minute ventilation, and then enter the humidifier, in which the gas is humidified and heated to the required temperature of the human body, and then sent to the patient through the breathing circuit, and the gas exhaled by the patient is discharged through the exhalation valve outside the machine, but the existing ventilators still have certain deficiencies when they are used

[0003] Existing ventilators often have the following problems when they are used: a: Existing ventilators often need to install rollers at the lower end of the ventilator in order to facilitate movement, so that when in use, the ventilator often moves due to external force interference, thereby causing the ventilator to move. The separation between the ventilator and the breathing tube poses a great potential safety hazard; b: when the existing ventilator performs gas delivery, the breathing tube is often placed freely, which often trips the human body, which makes the breathing tube and the breathing tube Machines are separated, there is a certain security risk
