The double-layer sac tracheotomy tube is the same as the existing tracheotomy tube in the aspect of tube placement, after the double-layer sac tracheotomy tube is placed, liquid medicine can be input into the slow release sac before a patient pulls out a tube and when the patient is in a sober belt, the liquid medicine can slowly, uniformly and continuously seep out of the mucous membrane of the trachea outside the wall of the slow release sac through the slow release sac wall under the action of the slow release sac, the stimulation of the tube to the trachea is relieved, the stress response of the patient is greatly reduced, and meanwhile, specific medicines such as vasoactive medicines, hormones, antibiotics and the like can be given through the combined action of the medicine storage sac 4 and the slow release sac 3 in the process of treating the patient.
The medicine storage bag 4 is made of an elastic material so as to force the medicine liquid in the medicine storage bag 4 into the slow release cavity 31 by utilizing the elastic retraction of the medicine storage bag 4, and preferably, the medicine storage bag 4 is provided with a medicine injection port 41. At this time, the external liquid medicine is input into the medicine storage bag 4 through the medicine injection port 41, and the liquid medicine in the medicine storage bag 4 is conveyed into the sustained release cavity 31 along the medicine injection tube 42 under the action of the elastic retraction force of the medicine storage bag 4 due to the elasticity of the medicine storage bag 4, so that the medicine slowly, uniformly and continuously seeps out of the tracheal mucosa outside the bag wall through the bag wall of the sustained release bag 3 under the action of the retraction force. The slow release capsule 3 is made of medical hydrophilic and hydrophobic nano composite materials, specifically, the medical hydrophilic and hydrophobic nano composite materials can comprise one of fluorine-containing macromolecules and polyurethane, and the pore diameter of a permeation hole on the slow release membrane is 1-100 nm. It is further noted that the cooperation of the elastic medicine storage bag 4 and the slow release cavity 31 makes the administration more durable and uniform.
