Methods and devices to clear obstructions from medical tubes
First Claim
1. A device for clearing obstructions from a medical tube, comprising a drainage canister having a drainage port for the introduction of material into the canister, and a vacuum port for connecting to a vacuum source to draw a suction through said canister, a guide-member actuator, and a guide member extending through said drainage port, said guide-member actuator being operable to advance and/or withdraw said guide member through said drainage port, said guide-member actuator comprising a biasing member to bias said actuator in either a normally-inserted position wherein the guide member is advanced to a maximum extent through said drainage port, or a normally-withdrawn position wherein the guide member is withdrawn to a maximum extent through said drainage port.

Abstract
A device for clearing obstructions from a medical tube, such as a chest tube, is disclosed in various embodiments. In embodiments, the device features a guide wire that extends from a drainage canister and can be advanced and withdrawn through a medical tube, such as a chest tube, via an actuator. The guide wire is actuated so as to maintain the sterile field within the chest tube and the associated suction pathway. Methods of clearing a medical tube of obstructions using such a device are also disclosed.

18. A device for clearing obstructions form a medical tube, comprising a drainage canister having a drainage port for the introduction of material into the canister, and a vacuum port for connecting to a vacuum source to draw a suction through said canister, a guide-member actuator, a guide member extending through said drainage port, said guide-member actuator being operable to advance and/or withdraw said guide member through said drainage port, and a CO2-sensor to detect the presence of CO2 in said drainage canister.
- 20. A method of clearing obstructions from a medical tube, comprising establishing fluid communication between said medical tube and an interior of a drainage canister for collecting material drained through said medical tube, drawing a suction through said medical tube and through said drainage canister in fluid communication therewith, and advancing a guide member that extends from said canister through said medical tube, said guide member being biased adjacent a proximal end thereof in a normally-inserted position wherein the guide member is advanced to a maximum extent through said drainage port.

25. A medical tube drainage system comprising:
-
a drainage canister having a fluid chamber; a drainage tube having a proximal end and a distal end, the proximal end being coupled to the drainage canister via a drainage port thereof, the drainage tube comprising a lumen therethrough, the drainage tube lumen being in fluid communication with the fluid chamber; a medical tube having a proximal end and a distal end, the medical tube comprising a lumen therethrough, the proximal end of the medical tube being coupled to the distal end of the drainage tube, the medical-tube lumen being in fluid communication with the lumen of the drainage tube; and a guide wire having a proximal portion terminating at a proximate end and a distal portion terminating at a distal end, the proximal portion of the guide wire extending through the fluid chamber and at least partially out of said drainage canister through an actuator port, the distal portion of the guide wire extending through the lumen of the drainage tube and into the lumen of the medical tube, wherein the guide wire is adapted such that the distal end of the guide wire can be extended into and withdrawn from the medical tube by pushing and pulling the guide wire proximal end, the distal end of the guide wire being adapted to dislodge obstructing material from the medical tube, the proximal portion of the guide wire being biased so that said proximal portion is in either a normally-inserted position wherein the guide wire is advanced to a maximum extent into said drainage canister through said actuator port, or a normally-withdrawn position wherein said proximal portion is withdrawn to a maximum extent from said canister through said actuator port. - View Dependent Claims (28, 29, 30, 31, 32)

26. A medical tube drainage system comprising:
-
a drainage canister having a fluid chamber; a drainage tube having a proximal end and a distal end, the proximal end being coupled to the drainage canister via a drainage port thereof, the drainage tube comprising a lumen therethrough, the drainage tube lumen being in fluid communication with the fluid chamber; a medical tube having a proximal end and a distal end, the medical tube comprising a lumen therethrough, the proximal end of the medical tube being coupled to the distal end of the drainage tube, the medical-tube lumen being in fluid communication with the lumen of the drainage tube; a guide wire having a proximal portion terminating at a proximate end and a distal portion terminating at a distal end, the proximal portion of the guide wire extending through the fluid chamber and at least partially out of said drainage canister through an actuator port, the distal portion of the guide wire extending through the lumen of the drainage tube and into the lumen of the medical tube, wherein the guide wire is adapted such that the distal end of the guide wire can be extended into and withdrawn from the medical tube by pushing and pulling the guide wire proximal end, the distal end of the guide wire being adapted to dislodge obstructing material from the medical tube; and
a sheath coupled to the drainage canister and the proximal end of the guide wire, the sheath adapted to contain that portion of the guide wire proximal portion that extends from the drainage canister through the actuator port, the sheath being flexible so as to allow expansion and contraction thereof as the guide wire proximal portion is withdrawn from and inserted into the drainage canister, respectively, through said actuator port. - View Dependent Claims (27)
