Problems solved by technology

[0002] Ventilators are often used in the medical field. Ventilators need to fully mix oxygen and air. The longer the air duct, the higher the mixing degree of oxygen and air. However, the length of the air duct will increase the size of the air duct module. It is beneficial to practical application; at the same time, the rapid flow of gas in the air duct will generate noise, and the increase in the size of the air duct module is not conducive to the setting of the sound-absorbing structure

Embodiment

[0028] Such as figure 1 , figure 2 and image 3 As shown, a spiral air duct module of a ventilator in this embodiment includes a housing 1 and an air duct module 2 disposed in the housing 1 , and the housing 1 is in the shape of a cuboid as a whole.

[0029] combine Figure 4 , the air duct module 2 includes a spiral air duct 21 and a sound-absorbing block 22 wrapped around the spiral air duct. The sound-absorbing block is made of sound-absorbing cotton material. The air channel 21 is arranged in the groove, so that the sound-absorbing block wraps the spiral air channel, and the sound-absorbing effect is good; the sound-absorbing block 22 is respectively provided with a first through hole 23 and a second through hole 24 on both sides of the spiral air channel 21, Moreover, the sound-absorbing block 22 is provided with a communication groove 25 connecting the first and second through holes on the back side, and the first oxygen inlet 26 is provided on one side of the air du...

Abstract

The invention relates to a breathing machine screw air duct module which comprises a rectangular shell and an air duct module body arranged in the shell. The air duct module body comprises a screw airduct and silencers, the silencers wrap the periphery of the screw air duct, a first oxygen inlet is formed in one side of the air duct module body, a first air inlet is formed in the other side of the air duct module body, the first oxygen inlet and the first air inlet are communicated and then connected with an inlet of the screw air duct, and an outlet of the screw air duct is formed in the center of the screw air duct. According to the breathing machine screw air duct module, the length of the air duct is prolonged by the aid of the screw air duct, so that oxygen and air are conveniently and sufficiently mixed.

Description

technical field [0001] The invention relates to an air duct module, in particular to a spiral air duct module for a medical ventilator. Background technique [0002] Ventilators are often used in the medical field. Ventilators need to fully mix oxygen and air. The longer the air duct, the higher the mixing degree of oxygen and air. However, the length of the air duct will increase the size of the air duct module. It is beneficial to practical application; at the same time, the rapid flow of gas in the air duct will generate noise, and the increase in the size of the air duct module is not conducive to the setting of the sound-absorbing structure. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a ventilator spiral air channel module capable of fully mixing oxygen and air. [0004] In order to achieve the above object, the technical solution proposed by the present invention is: a spiral air duct module for ...
