  • Design and Control of a Mechatronic Tracheostomy Tube for Automated Tracheal Suctioning
    IEEE Transactions on Biomedical Engineering, 2016
    Co-Authors: Thanh Nho Do, Tian En Timothy Seah, Soo Jay Phee
    Abstract:

    Goal: Mechanical ventilation is required to aid patients with breathing difficulty to breathe more comfortably. A tracheostomy tube inserted through an opening in the patient neck into the trachea is connected to a ventilator for Suctioning. Currently, nurses spend millions of person-hours yearly to perform this task. To save significant person-hours, an automated mechatronic tracheostomy system is needed. This system allows for relieving nurses and other carers from the millions of person-hours spent yearly on tracheal Suctioning. In addition, it will result in huge healthcare cost savings. Methods: We introduce a novel mechatronic tracheostomy system including the development of a long Suction Catheter, automatic Suctioning mechanisms, and relevant control approaches to perform tracheal Suctioning automatically. To stop the Catheter at a desired position, two approaches are introduced: 1) Based on the known travel length of the Catheter tip; 2) Based on a new sensing device integrated at the Catheter tip. It is known that backlash nonlinearity between the Suction Catheter and its conduit as well as in the gear system of the actuator are unavoidable. They cause difficulties to control the exact position of the Catheter tip. For the former case, we develop an approximate model of backlash and a direct inverse scheme to enhance the system performances. The scheme does not require any complex inversions of the backlash model and allows easy implementations. For the latter case, a new sensing device integrated into the Suction Catheter tip is developed and backlash compensation controls are avoided. Results: Automated Suctioning validations are successfully carried out on the proposed experimental system. Comparisons and discussions are also introduced. Significance: The results demonstrate a significant contribution and potential benefits to the mechanical ventilation areas.

  • Design and control of a novel mechatronic tracheostomy tube-inserted Suction Catheter for automated tracheal Suctioning
    2015 IEEE 7th International Conference on Cybernetics and Intelligent Systems (CIS) and IEEE Conference on Robotics Automation and Mechatronics (RAM), 2015
    Co-Authors: Thanh Nho Do, Tian En Timothy Seah, Soo Jay Phee
    Abstract:

    Mechanical ventilation is required to aid patients with breathing difficulty to breathe more comfortably. A tracheostomy tube is inserted through an opening in the patient neck into the trachea, below the vocal cords. This opening is either created surgically or using a percutaneous dilatational technique. The inserted tube sits in the trachea, above the carina, and before the airways branch into the left and right main bronchi. In mechanical ventilation, the tube is connected to a ventilator and air is moved in and out of the lungs via positive pressure. In this process, mucus will accumulate at the point of branching into the branchi. Currently, this mucus is manually removed half-hour by inserting a Suction tube via the tracheostomy to reach the point of branching. Nurses spend millions of person-hours to perform this task yearly. To save significant person-hours, an automated system is needed. This system also allows the patient to recover at home, rather stay in hospital solely for nurses to remove mucus periodically. In this paper, we present a novel mechatronic device to perform automatic tracheal Suctioning in conjunction with a tracheostomy tube. A new Suctioning Catheter is also developed. It is known that nonlinear friction and backlash between the Suctioning Catheter and its conduit as well as in the gear system of the actuator cause difficulties to accurately control the position of Catheter tip. To enhance the system performances, a novel direct inverse of backlash-like hysteresis model-based feedforward is also developed. The designed device and proposed compensation scheme are experimentally validated. The results demonstrate a significant contribution and potential benefits to the mechanical ventilation works.
