Abstract
A balloon device for a rigid bronchoscope includes a balloon shaft member; a balloon member connected to the balloon shaft member; and an inflation device operably connected to the balloon shaft member and the balloon member. The inflation device configured to adjust an inflation level of the balloon member. The inflatable and adjustable balloon device is configured to fit snugly on the outside of the rigid bronchoscope. This enables better ventilation of patient's undergoing rigid bronchoscopy and prevents back bleeding into the lung. Once the balloon is inflated, improved jet ventilation can occur with better resulting aeration.
Claims7
A rigid bronchoscope assembly comprising:
- a rigid bronchoscope including a barrel having an outer surface;
- and
- a balloon device disposed on the outer surface of the barrel, the balloon device comprising:
- a balloon shaft member comprising a hollow tube;
- a balloon member connected to a first end of the balloon shaft member, the balloon member configured to fit over and extend circumferentially around the barrel of the rigid bronchoscope and, when inflated, to expand radially outward from the barrel to form a seal between the outer surface of the barrel and an airway wall;
- an air installation port connected to a second end of the ballon shaft member away from the ballon member;
- an inflation device comprising a pump and a valve, the inflation device connected to the air installation port, the inflation device configured to regulate a flow of inflation fluid into and out of the balloon member through the air installation port and adjust an inflation level of the balloon member in order to create the seal;
- and
- a metal string member having an adjustable circular shape connected to an end of the balloon shaft member, the balloon member being connected to the metal string member, wherein a change of a diameter of the metal string member causes a corresponding change in a diameter of the ballon member around the outer surface of the barrel.
A rigid bronchoscope comprising:
- a rigid tubular barrel member configured for insertion into an airway of a patient, the barrel member having an outer surface and a distal tip;
- an inflatable balloon member disposed circumferentially around the outer surface of the barrel member near the distal tip;
- a balloon shaft member comprising a hollow tube connected to the balloon member and extending proximally along the barrel member;
- an inflation device comprising a pump and a valve, the inflation device connected to the balloon shaft member and the balloon member and configured to regulate a flow of inflation fluid into and out of the balloon member to adjust an inflation level of the balloon member so as to form a seal between the barrel member and a wall of the airway;
- a metal string member having an adjustable circular shape connected to an end of the balloon shaft member, the balloon member being connected to the metal string member, wherein an adjustment of a diameter of the metal string member causes a corresponding change in a diameter of the balloon member around the outer surface of the barrel;
- and
- wherein the balloon shaft member is further configured to slidably move the balloon member along a length of the barrel member.
