Description

Technical Field

[0001] The invention relates to the technical field of medical gases, and in particular to an automatically switchable medical gas bus device. Background Art

[0002] A gas bus device is a device used to collect and distribute gas, and is widely used in industries, laboratories, and medical fields. Its main function is to collect gas from multiple gas sources to a common outlet, thereby achieving the rational distribution and use of gas. This device usually consists of multiple gas input ports, one or more gas output ports, a regulating valve, a flow meter, etc. The gas enters the bus through the input port, is flow-controlled by a regulating valve, and then is transported to where it is needed. The design of the gas bus device needs to fully consider the properties of the gas, such as pressure, temperature, and corrosiveness, to ensure safe and efficient operation. In laboratories, gas buses are often used in gas supply systems, such as the preparation and supply of oxygen, nitrogen, or helium. In the medical field, it is commonly found in anesthesia machines or ventilators to provide necessary oxygen and anesthetic gases. In industrial production, it can effectively manage the supply of multiple gases and improve production efficiency.

[0015] The present invention has the following beneficial effects:

[0016] 1.

[0017] 2. The automatically switchable medical gas bus device adopts the setting of a blocking block. The blocking block cooperates with the piston disc to control the piston disc under the blocking block to avoid blockage of the first gas bottle. If the locking rod does not separate the piston block from the airway tube, the continuous inhalation air pressure will also suck out the piston block. The cooperation of the first pull ring, the second pull ring and the third pull ring facilitates the subsequent installation of the piston block, ensures the smooth supply of gas, and prevents the interruption of gas supply due to the improper separation of the piston block.

[0018] 3. The automatically switchable medical gas bus device is provided with a self-locking component. The self-locking component cooperates with the first locking disk and the first gas bottle to thread the connecting bolt into the first threaded hole and the second threaded hole, and then press the abutment column, so that the block inside the abutment column is squeezed with the first snap cap. The telescopic column and the spring are compressed, so that the block is snapped between the first snap cap and the second snap cap. When disassembly is required, the abutment column is pressed again, and the block cooperates with the second snap cap and the third snap cap. The moment the force is loosened, the abutment column and the connecting core bolt are unlocked. The self-locking component ensures that the connection remains stable under normal working conditions, avoiding accidental loosening or falling off during the gas supply process, improving the safety of the system, ensuring the safety of patients and medical staff, and making the entire solution better.
