Technical Field
The utility model relates to the technical field of medical instruments, in particular to a coaxial mechanical spray dosing and humidifying device in a breathing machine pipeline.
Background
At present, a humidifying device of a household respirator adopts electric heating humidification. Such devices are clearly not useful for administering drugs because they do not produce significant water mist. In addition, if the drug is not sensitive to heat, such a humidifier cannot be used if the drug cannot self-evaporate in a large amount. In addition, as a humidifying device, the southern Chinese people cannot turn on the air conditioner in winter, so that condensed water can be generated in the pipeline, and the experience is poor. In fact, continuous humidification is not needed when using the respirator.
Ultrasonic humidification seems simple and effective, but is often difficult to control for use in a ventilator, and ultrasonic waves do not destroy the molecular formula of the drug when blasting the liquid, and it is difficult to say that at least this process itself is a local high temperature process. In addition, in winter, the humidifier can be used for humidifying during sleeping, only one or two times of mist spraying are needed to be performed occasionally near the nose, and the mist spraying is not needed to be performed continuously.
Other atomising devices often require high pressure air, which is obviously inconvenient and also causes some noise. Therefore, there is a need to develop a device for administering a nebulized medication from a ventilator circuit. The device is different from the existing continuous spraying device, and can accurately administer medicine or humidify according to times.
