Problems solved by technology
[0002] The applicant applied on October 28, 2011, the patent number is ZL201110333596.3, and the invention patent named "a CPAP oxygen supply instrument with dual gas sources" can theoretically solve the problem of air and oxygen in CPAP oxygen supply instruments. A gas source problem, but the clinical oxygen required by this equipment is generally 6-8L / min, with a maximum of 15L / min or more
At present, the miniaturization of mobile equipment, the use of PSA technology to achieve oxygen production flow generally can only reach below 8L / min, to achieve greater oxygen production, the usual practice is to use a compressor with a larger air supply, so that , the side effects of high-flow compressors such as heat and noise are very obvious, and it is actually not easy to meet the quiet requirements of hospital wards
At the same time, once a failure occurs in this way, there will be a risk of complete gas failure

Embodiment Construction
[0010] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:
[0011] like figure 1 As shown, an easy-to-implement safe dual-gas source oxygen mixer is used in hospitals to supply oxygen to patients in clinical practice. Oxygen supply pipeline, each air circuit all adopts oil-free air compressor pump 3, 3' of small flow rate (less than 8L / min).
[0012] Wherein, the first gas pipeline includes: a first oil-free air compressor 3 connected in series through the gas pipeline, a first air / oxygen separation parallel flow path, a pressure reducing valve 14, a throttle valve 15, a first A one-way valve 18 and a breathing mask 22, and a pressure sensor 21 is parallelly connected between the first one-way valve 18 and the breathing mask 22; wherein, the first air / oxygen separation parallel flow path includes mutually parallel regulating A pressure valve branch and an oxygen production branch, the oxygen production bran...

The invention provides a safe double-air-source mixed oxygen instrument and an oxygen supply method thereof and belongs to the technical field of medical instruments. The safe double-air-source mixed oxygen instrument comprises a double-gas-circuit oxygen supply pipeline of a first gas pipeline and a second gas pipeline, wherein each gas circuit is provided with a small flow of oil free air compressor pump. The oxygen supply method of the safe double-air-source mixed oxygen instrument comprises the following steps of S1, determining the oxygen supply scheme according to the condition of a patient and performing oxygen supply settings through monitoring on a display and control device; S2, setting one of the gas pipelines to perform the oxygen supply when the required oxygen flow is smaller than 8 liters every minute; S3, setting the two gas pipelines to perform the oxygen supply simultaneously when the required oxygen flow is larger than 8 liters every minute; S4, starting the mixed oxygen instrument for the oxygen supply after the settings are achieved. According to the safe double-air-source mixed oxygen instrument and the oxygen supply method thereof, the oxygen supply is safe, the noise is small, the energy is saved, and the like.
