Abstract: A device for positioning tracheostomy tube includes a tracheostomy tube and a tracheostomy tube protecting membrane. The tracheostomy tube protecting membrane includes a tearing line portion formed at two sides of the tracheostomy tube protecting membrane. The tracheostomy tube protecting membrane is used for mounting in a trachea of a patient to form a positioning path for the tracheostomy tube. The tearing line portion is used for being torn open and removed. The present invention utilizes the tracheostomy tube protecting membrane to be mounted in a trachea of a patient first. The tracheostomy tube protecting membrane can effectively protect the trachea of the patient.

Abstract: An injection base for artificial blood vessels includes a body and a catheter. The body has an injection chamber, a strengthened injection top diaphragm and a strengthened injection side diaphragm. The catheter is connected to one side of the body, and the strengthened injection side diaphragm is at another side of the body according to the catheter. The body and the catheter are integrated as one member. The totally implantable central venous access port further has a metal wire, which is coated with a film, and a puncture sheath with a side opening in order to make a loop around the metal wire through the puncture sheath conveniently. For the cases of a small blood vessel and a large angle of a blood vessel, the totally implantable central venous access port is easily implanted into and reinforces the strength thereof.
