Abstract

The invention provides an automatic pressure stabilizing device for a tracheal intubation airbag of a hyperbaric oxygen chamber. The automatic pressure stabilizing device for the tracheal intubation airbag of the hyperbaric oxygen chamber comprises a one-way air supply valve, a tee pipe connector, the intubation airbag, an air conveying pipe and an air pressure indicator, and is characterized in that a pressure sensor and a pressure release solenoid valve are installed on the air conveying pipe; the output end of the pressure sensor is connected to the signal input end of a pressure controller; the control output end of the pressure controller is connected with the pressure release solenoid valve; the pressure sensor, the pressure controller and the working power source end of the pressure release solenoid valve are connected with a power supply. When the pressure inside the intubation airbag exceeds a standard value, air inside the intubation airbag is discharged out automatically, the air pressure inside the intubation airbag is reduced, air discharge is stopped automatically after the pressure inside the intubation airbag reaches the standard value, and the pressure of the intubation airbag keeps at the safe and stable value all the time in the process of a hyperbaric oxygen operation. Meanwhile, the air pressure can be displayed, an alarm is given in high pressure or low pressure, and the safety and reliability of the treatment of the hyperbaric oxygen operation are improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a medical hyperbaric oxygen operation auxiliary equipment, in particular to a hyperbaric oxygen chamber tracheal intubation air bag automatic pressure stabilizing device. Background technique [0002] In the process of hyperbaric oxygen surgery, the air source is first injected into the intubation airbag of the human body through the air valve, so that the pressure in the intubation airbag is higher than that of the cabin and kept at 25-30cmH 2 O. After the operation, the pressure in the hyperbaric oxygen chamber drops. During the decompression process, the gas in the intubation balloon used in the patient's operation will expand, and the inflation pressure exceeds 25-30cmH 2 O will cause harm to the human body. Therefore, measures need to be taken to keep the pressure of the intubation balloon at 25-30 cmH 2 O. [0003] At present, the traditional method is to use a sy...
