Abstract

The invention relates to the technical field of medical instruments, in particular to a fan. The fan includes a housing, an impeller and a motor; the housing is provided with an air inlet and an air outlet; the impeller is located inside the housing and is close to the air inlet; the output shaft of the motor is connected to the The impeller, so that the gas flows along the direction of the air inlet towards the air outlet; the space inside the housing for containing the gas is the gas flow space in the shell; the volume of the gas flow space in the shell is related to the The ratio range of the volume of the impeller is 15-30; the housing has an air outlet channel, and the air outlet channel communicates with the air outlet; along the direction of the gas outlet flow, the outlet air A plurality of arc-shaped grooves are uniformly arranged on the inner wall of the channel. The purpose of the present invention is to provide a fan to improve the stability of the output pressure and flow of the fan.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a fan. Background technique [0002] Fans are widely used in the medical field, especially ventilators. In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. [0003] However, the pressure and flow output by the existing fans are unstable, which directly affects the quality of medical equipment such as ventilators, and even affects the saving and prolonging of patients' lives.
