Problems solved by technology

However, with the increase of turbine power, the jitter will increase when the turbine speed is adjusted, and the noise of the turbine will also increase, requiring more noise reduction measures; and with the increase of turbine power, the power consumption of the turbine will also increase. Larger, the turbine heat increases, and more turbine cooling measures are also required
Therefore, the respiratory support equipment in the prior art has the disadvantages of relatively large pressure regulation delay, high noise and high heating power

Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] refer to figure 1 , the present invention provides a respiratory support device, including an airway 1 , a turbine 2 arranged on the airway 1 , an air storage unit 3 , a first pressure sensor 4 , a flow control valve 5 and a second pressure sensor 6 .

[0019] The airway 1 is set in the respiratory support device, one end of which is an air inlet 11, which is the air intake of the respiratory support device, and the other end is an air outlet 12, which is the air outlet of the respiratory support device. Gas ...

Abstract

The invention discloses a respiratory support device including a turbine; the respiratory support device also includes a gas way, a gas storage unit arranged on the gas way, a first pressure sensor, aflow control valve and a second pressure sensor. The invention also discloses a control method of the respiratory support device. Compared with the prior art, the respiratory support device and the control method thereof have smaller pressure regulating delay, lower noise and smaller heating power.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a respiratory support device and a control method thereof. Background technique [0002] Existing respiratory support equipment supplied by a turbine calculates the pressure value that the respiratory support equipment needs to output at the current moment through the data detected by the pressure sensor, and according to the value detected by the pressure sensor, the closed-loop control turbine quickly reaches this pressure value and sends it to the user. Therefore, the basis of adjusting the output pressure is to adjust the turbine speed, the higher the turbine speed, the greater the pressure of the output gas. [0003] However, because the rotation speed of the turbine cannot be changed suddenly, the adjustment process takes time, and the pressure transmission delay in the airway inside the respiratory support device causes a delay in pressure adjustment. For example...
