Abstract

The invention relates to a medical trachea cannula and relates to a novel percutaneous tracheotomy cannula to overcome the defects that the prior art plastic cannula has a thick wall, high airway resistance, high mutual friction coefficient, difficulty in implanting during surgery, poor inter-cannula tightness, inconvenience of inner cannula changing, high cost and inconvenience of sterilization.To solve the technical problems, the novel percutaneous tracheotomy cannula comprises inner and outer metal sleeves, a plastic balloon and a hollow core; the novel percutaneous tracheotomy cannula is characterized in that the modified inner and outer metal sleeves and hollow core are fit with inner and outer plastic balloons, better tightness is provided between the trachea cannulas as well as between the trachea cannula and the airway, the defects that the plastic trachea cannula is difficult to implant during surgery and the metal trachea cannula is unable to be connected with a ventilator for use are solved, the defect that the cannula has thick wall, high ventilation resistance and convenience of changing is also overcome, and this cannula has the advantages of better economy, environmental friendliness, convenience and durability.

Description

New Percutaneous tracheostomy cannula

Technical field

This patent relates to medical device technical field, is specifically related to a kind of New Percutaneous tracheostomy cannula.

Background technology

In curative activity, percutaneous tracheotomy is that a kind of Wicresoft, quick artificial airway set up mode. The percutaneous tracheostomy cannula commonly used clinically is plastic, although artificial airway can be set up, but find to have the disadvantage that 1. the mutual coefficient of friction of plastic is big in clinical practice is applied, insert resistance during tracheal casing pipe big, usually occur inserting difficulty, easily cause bleeding due to trauma, or cause serious complication such as tracheal collapse because strength is excessive, and very easily cause trocar sheath to deviate from when changing or inner sleeve inserts difficulty, increase the risk of damage air flue; 2. inner sleeve and trocar sheath cannot fully effective be closed, and have gas leak phenomenon, particularly in patients with mechanical ventilation, it is impossible to ensure effective ventilatory volume; 3. inside and outside tube wall is all thicker, and when same caliber size, tube chamber is obviously reduced, and adds airway resistance and tracheal casing pipe expectorant bolt blocking risk during ventilation; 4. the general only standby two set inner sleeves of a set of trocar sheath, during relatively thickness as more in patient's sputum, inner sleeve quantity is substantially not enough, it is impossible to replacing timely, on-demand; 5. plastic is disposable product, causes very large resource waste, and cost of use is also higher; 6. plastics inner sleeve, sterilization equipment requirements is higher, Disinfection Effect cannot be ensured at basic hospital.
