A kind of warm and humid exchange filter of above-mentioned tracheostomy tube, the diameter range of the hemispherical shell is 24 ~ 50mm。

A kind of warm and humid exchange filter of above-mentioned tracheostomy tube, the hemispherical shell are PVC or silica gel material It constitutes.

A kind of warm and humid exchange filter of above-mentioned tracheostomy tube, the raised type infusion connector are medical 1:Outside 40 Locked joints are located at the spherical surface lower edge and back plate connections of hemispherical shell.

A kind of warm and humid exchange filter of above-mentioned tracheostomy tube, the filtering sponge and corrugation roll paper, are filled in Mode inside Loadings On Hemispherical Shell is first to put corrugation roll paper layer, then stack filtering on the basis of hemispherical shell inside bottom plane Sponge.

A kind of warm and humid exchange filter of above-mentioned tracheostomy tube, the pore are arranged in " rice " font or circular hole In on hemispherical shell spherical surface and bottom plate.

A kind of warm and humid exchange filter of above-mentioned tracheostomy tube, the concave inner circle taper joint, can with it is corresponding The outer circle taper joint of model connects.

A kind of warm and humid exchange filter of above-mentioned tracheostomy tube, the connection type of the hemispherical shell and bottom plate For fastening, spiral interlocking, bonding.

Possessed advantageous effect is the utility model compared with prior art：

1. volume is light and handy, moderate, light-weight, patient is facilitated to carry；

2. using concave inner circle taper joint, can be connect with the incision cannula of arbitrary medical modular connection；

3. raised type infusion connector can be connect with the infusion pipeline of arbitrary medical standard cock, and because being located at lower edge, can be prevented There is ponding when only humidification amount is excessive；

4. inside corrugation roll paper is below, filtering sponge, and can be with above with corrugated paper moisture absorption and support function When preventing humidification amount excessive, the excessive completely plugged air duct of continuous water suction is filtered.
