Description

Children's suction tube with adjustable suction force

Technical Field

The utility model relates to the technical field of sputum suction tubes, in particular to a sputum suction tube for children with adjustable suction force.

Background Art

The suction tube is made of medical polymer materials and consists of a catheter and a connector. It is divided into six specifications according to different tube diameters. The end where the connector is located is connected to the suction device to suction the patient's sputum.

Currently, there is a lack of suction tubes specifically suitable for children. When using general catheters to suction pediatric patients, the suction force of the suction tube is difficult to adjust. When children have a lot of sputum in their respiratory tract, if the suction force of the suction tube is small, the sputum suction time will be prolonged. If children have less sputum in their respiratory tract and the suction force of the suction tube is large, it will cause discomfort to the child, and the suction tube cannot be removed quickly and in time, affecting its efficiency.

Based on this, a pediatric suction tube with adjustable suction force is now provided to eliminate the disadvantages of existing devices.
