Abstract: Mouthpiece (1) having vestibular shield (21) overlapping a user's teeth and gums, gases passageway means extending through said vestibular shield allowing for the passage of said gases through mouthpiece and extra oral sealing (25) means associated with gases passageway, said passageway in use causes gases to be diffused (outlets 23, 24) when exiting from gases passageway. Mouth piece may have a noseflap to seal the user's nose or provide a passageway for use'r s nasal passages. Mouthpiece may have adjustment means to alter distance between said vestibular shield and said extra-oral sealing means.

Abstract: Tracheostomy apparatus includes a needle with a doppler ultrasound transducer mounted within it close to its patient end and connected to a monitor. Two electrodes are insulated from one another on the external surface of the needle close to its patient end. The electrodes are also connected to the monitor. The needle supports a catheter on its outer surface. As the needle is inserted through tissue overlying the trachea, the ultrasound transducer detects the presence of any nearby blood vessels and gives an audible indication on the monitor. The monitor also responds to a rise in impedance between the electrodes indicative of entry of the end of the needle into the trachea so that the needle can be removed to leave the catheter in place. A guide is then inserted through the catheter and the path into the trachea is enlarged with a dilator sufficiently to receive a tracheostomy tube.

Abstract translation: 气管造口术装置包括具有多普勒超声换能器的针，其安装在其内靠近其患者端并连接到监视器。 两根电极在靠近患者端的针的外表面上彼此绝缘。 电极也连接到显示器。 针在其外表面上支撑导管。 当针穿过覆盖气管的组织时，超声换能器检测到任何附近血管的存在，并在监护仪上给出可听见的指示。 监测器还响应电极之间的阻抗上升，指示针头进入气管，使得针可以被移除以使导管离开原位。 然后将引导件插入通过导管，并且用扩张器扩大进入气管的路径以充分接收气管造口管。
