Abstract

The invention provides a draught fan device and a breathing machine with the same. The draught fan device comprises a shell, a draught fan body and a support. The shell comprises an upper cover, a middle frame and a lower cover. A closed cavity is formed by the upper cover, the middle frame and the lower cover, and a first air channel is formed by the upper cover and the middle frame. The shell isprovided with a first air inlet, a second air inlet and an air outlet. The draught fan body is installed in the cavity through the support. The draught fan body comprises a draught fan air inlet anda draught fan air outlet. A second air channel is formed by the support and the cavity. By means of the first air channel and the second air channel, the airflow entering the draught fan body 2 can beeffectively guided so that the airflow can be smoother, meanwhile, the outward transmission path of noise is increased, and therefore the noise generated in the running process of the draught fan device is effectively reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a fan device and a ventilator using the fan device. Background technique [0002] Ventilator is a device that can replace, control or change people's normal physiological breathing. It is often used to increase the patient's pulmonary ventilation, improve the patient's respiratory function, reduce the consumption of respiratory power, and save the patient's heart reserve capacity. [0003] The blower unit is an important part of the ventilator, which is used to pressurize the breathable gas and deliver it to the patient. The existing fan device has the problems of high noise and poor airflow smoothness of the air passage. Contents of the invention [0004] In order to solve the technical problems in the prior art, the present invention provides a fan device and a ventilator using the fan device (with it). The purpose is to improve the smoothness of air flow in the air passage...
