Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically to an infection-proof barrier type sputum suction connecting cap. Background Art

[0002] The traditional method of disinfecting the suction connecting tube is to rinse the suction connecting tube with saline after suctioning, and then insert the front end of the connecting tube into a glass bottle containing disinfectant (furacilin solution) fixed to the bedside rail to soak for use. In clinical practice, patients, especially those in intensive care units, need suction. The traditional suction connecting tube is directly connected to the end of the suction tube after suctioning, which is easy to cause residual sputum and increase the risk of infection.

[0003] The article "Investigation on the main infectious bacteria contaminating the interface of the suction connecting tube and the application effect of the medical infusion bottle mouth patch" discloses that the use of a medical infusion bottle mouth patch to seal the connecting tube can reduce the infection rate. Its construction method is to rinse the suction connecting tube with saline after suctioning, and then directly use the medical infusion bottle mouth patch to seal the connecting tube interface. The disadvantage is that the infusion bottle mouth patch is not firm enough and is easy to fall off after long-term use. It is inconvenient to fix the suction connecting tube after the infusion patch is applied. Summary of the invention
