Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a vehicle-mounted portable ventilator, which belongs to the technical field of ventilators. Background Art

[0002] A ventilator is a device that can replace, control, or change a person's normal physiological breathing, increase pulmonary ventilation volume, improve respiratory function, reduce the consumption of respiratory work, and save the heart's reserve capacity.

[0003] Existing ventilators include large floor-standing ventilators with a relatively large volume that can be moved on the ground. This type of ventilator is mainly used for invasive patients to assist breathing or provide respiratory support. When existing emergency ventilators are used for on-vehicle patient rescue, since they need to be connected to an external air source for use or an oxygen cylinder needs to be carried, they occupy a large space on the ambulance, are inconvenient to carry, and the gas cylinders need to be frequently replaced or oxygen needs to be refilled. In the case of long-distance patient transfer, their use will be restricted.

[0004] Existing ventilators also include horizontal small ventilators. This type of ventilator is mainly used to treat patients with snoring or apnea and pulmonary insufficiency. The patients have spontaneous breathing, that is, there is no major problem with normal breathing, and they will not be in life danger if they are separated from the ventilator.

[0028] A medical small air compressor, a pressure reducing valve, an oxygen concentration regulating valve, a tidal volume regulating valve, a first solenoid valve, a second solenoid valve, an oxygen sensor, a safety valve, and a flow sensor are arranged inside the chassis.

[0029] The inner end of the air inlet joint is fixedly connected to a gas input interface end of a medical mini air compressor pump. The inner end of the oxygen inlet connecting pipe head is connected to the input end of a pressure reducing valve. The output end of the pressure reducing valve is connected to the input end of an oxygen concentration regulating valve. The output end of the oxygen concentration regulating valve is connected to another gas input interface end of the medical mini air compressor pump. Among them, the regulating end of the oxygen concentration regulating valve is fixedly connected to an oxygen concentration regulating knob. By rotating the oxygen concentration regulating knob to different positions, the regulation of the oxygen concentration is realized, that is, the regulation of the oxygen delivery amount, so as to achieve the control of the oxygen concentration. Through the dual-interface input mode of air and oxygen, the alternative or simultaneous input of air and oxygen can be realized.

[0030] The output end of the medical mini air compressor pump is respectively connected to the gas input interface of a tidal volume regulating valve and the gas input port end of a first solenoid valve through two branch pipelines. Among them, the regulating end of the tidal volume regulating valve is fixedly connected to a tidal volume regulating knob. By rotating the tidal volume regulating knob to different positions, the regulation of the inhalation volume is realized. The gas output end of the tidal volume regulating valve is connected to the gas input end of a second solenoid valve.

The first interface is fixedly connected to the inner end of a safety air inhalation joint. An oxygen sensor is installed at the second interface, a safety valve is installed at the third interface, and a flow sensor is installed at the fourth interface. The safety air inhalation joint is used to realize the auxiliary input of air.

When the gas pressure is too high, pressure relief control is realized through the safety valve. The flow sensor is used to realize the flow detection of the output gas.

[0031] The air outlet of the above inhalation port connecting pipe and the air inlet of the exhalation valve are connected to a breathing mask through an inner and outer sleeve type inhalation pipe (the inhalation pipe and the breathing mask are not shown in the attached drawings). Among them, the inner pipe is used to transport the gas discharged from the inhalation port connecting pipe to the exhalation mask. As the patient inhales, the inhalation of oxygen is realized. And the annular cavity between the inner and outer pipes is used to transport the gas exhaled by the patient to the exhalation valve and finally output through the exhaust port of the exhalation valve.

[0032] The above first solenoid valve is used to realize the on-off control of inhalation, and the second solenoid valve is used to realize the control of exhalation discharge. The control system of the ventilator controls the two solenoid valves to open and close simultaneously. The air inlet and the exhaust port of the above exhalation valve are in a connected state under normal conditions. When the second solenoid valve is opened, external air or other inputs drive the control element to move, realizing the cut-off of the passage between the air inlet and the exhaust port. And when the second solenoid valve is closed, the air inlet and the exhaust port of the exhalation valve are connected, realizing the discharge of the exhaled gas.

[0033] The detection values of the above oxygen sensor, flow sensor, etc. are displayed on the display screen, facilitating the adjustment of oxygen concentration and tidal volume according to the actual situation of the patient.
