Description

Anti-winding type medical ventilator bellows

Technical Field

The utility model relates to a bellows technical field especially relates to an antiwind formula medical treatment breathing machine bellows.

Background

The corrugated pipe is a tubular elastic sensitive element which is formed by connecting foldable corrugated sheets along the folding and stretching direction. The corrugated pipe has wide application in instruments and meters, and is mainly used as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The corrugated pipe has thin pipe wall and high sensitivity, and the measurement range is from tens of Pa to tens of MPa. Its open end is fixed and its sealed end is in free state, and an auxiliary spiral spring or reed is used to increase elasticity. When working, the pipe is extended along the length direction under the action of internal pressure, so that the movable end generates displacement in a certain relation with the pressure. The movable end drives the pointer to directly indicate the pressure. Bellows are often combined with displacement sensors to form pressure sensors that output an electrical quantity, sometimes also acting as isolation elements. The response speed of the bellows is slower than that of the bourdon tube because of the large volume change required for the expansion of the bellows. The bellows is adapted to measure low pressure.

When the corrugated pipe used for connecting the breathing machine is produced, the pipe body structure of the corrugated pipe is required to be ensured not to be extruded, the sectional area in the pipeline is reduced due to the extrusion, and the extruded corrugated pipe structure is easy to damage when being used, so that the communication effect of the corrugated pipe is influenced, namely the existing corrugated pipe is lack of a necessary anti-winding structure, and the damage of the pipe body structure caused by winding is avoided.
