Apparatus and methods for clearing obstructions from a medical tube are disclosed. In an exemplary embodiment, a spool drive system is disclosed for actuating a guide wire within a medical tube. The spool drive system can be a hand held, disposable device having a spool housing with a spool therein for alternately advancing and withdrawing a guide wire through an inlet of the spool housing. A track can be spaced from and extend about a perimeter of the spool to direct the guide wire onto or off of the spool as the spool is rotated. Other embodiments and devices for actuating the guide wire, and methods therefor, also are disclosed.

A flexible pipe containment sled includes a platform and a first sled portion coupled to a bottom surface of the platform. The first sled portion is disposed at a first side of the platform. The sled also includes a second sled portion coupled to the bottom surface of the platform. The second sled portion is disposed at a second side of the platform opposite to the first side of the platform. The sled also includes a passage formed between the first and second sled portions. The passage is configured to allow a flexible pipe to pass through the passage while the flexible pipe containment sled is placed on a surface.

Retractor systems are disclosed that reduce the wear on the retractor line from repeated extensions and retractions. Some embodiments comprise a retractor system having a retractor with a retractor housing having a front surface. A line and a line retraction mechanism can be included within the housing, with the line retraction mechanism urging retraction of the line in a first direction that is substantially parallel to the front surface. A line opening is included in the front surface through which the line extends from the housing at a second direction that is different from the first direction. A personal article attached to the line, and an anti-friction mechanism is included at said line opening to provide a smooth surface upon which the line rides when extending from the housing. Some anti-friction mechanisms comprise an eyelet proximate to said line opening and having a smooth surface that can take many different shapes and sizes, such as a funnel or hour glass shaped surface.

A vehicle-mounted reel utility. A brake wheel is macro-positioned to a non-contact position adjacent to the reel by sliding along a reel-supporting lifting arm. An actuator pivots the brake bracket bringing the wheel into a contact position with the reel. A cable dispenser for figure 8'ing the cable is mounted to the free end of a positioning arm that rotates from a position parallel to a lifting arm to a position perpendicular to the lifting arm. The dispenser is pivotally mounted to the positioning arm, allowing the user to swivel the dispenser about a horizontal arc while maintaining the dispenser in a central lateral position relative to a reel or a vehicle during the swivel movement. A hydraulic circuit controls the dispenser and the actuator that controls the brake wheel from a contact to non-contact position, to coordinate the stopping of cable dispensing.

A device for storing a rope for a descender includes the rope, a rope drum, and a dimensionally stable rope bag, wherein the rope has a diameter of less than or equal to 8 mm and is at least partially wound on the rope drum in such a way that a first end of the rope can be unwound from the rope drum, and wherein the rope drum is disposed in the rope bag in such a way that the first end of the rope can be led out of an opening) of the rope bag. Furthermore, an assembly includes a descender and the above-mentioned device, wherein the descender includes a centrifugal brake configured such that a rope passing through the descender can be slowed down in its motion, and wherein the rope of the device is passed through the descender.

A curtain reel structure for assembling a blind cord rapidly is disclosed herein. It mainly comprises a winding spool, a reel seat on which the winding spool is assembled, a first positioning device disposed between the winding spool and the reel seat and having a first chamber and a first sliding seat inserted into the first chamber, wherein the first sliding seat is provided with a first accommodating slot for accommodating the blind cord, and a second positioning device disposed between the winding spool and the reel seat and having a second chamber and a second sliding seat inserted into the second chamber, wherein the second sliding seat is provided with a second accommodating slot for accommodating the blind cord.

An auxiliary distribution station is configured to be used in cooperation with a primary distribution station. The auxiliary distribution system includes a mobile vehicle, an auxiliary hose reel and auxiliary hose, a lift, a tank, a pump, an auxiliary meter, and a tank hose. The auxiliary hose is configured to be fluidly connected with a hose of the primary distribution station. The lift is configured to move and deploy the auxiliary hose reel from the mobile vehicle. The pump is operable to pump fluid from the tank, through the meter, and through the tank hose.

A spool apparatus is described to include in one particular example a cable spool with a first cylindrical lip and a second cylindrical lip on an opposite side of the cable spool. A center of the spool includes a clutch bearing in the center of both the first cylindrical lip and the second cylindrical lip that provides a rotational axis for the cable spool to rotate around. The apparatus may also include a feed slot near the first cylindrical lip that provides a passage for cable to pass from the second cylindrical lip to the first cylindrical lip.

A pull-out type cord winding module, comprising a rotary wheel (6) which a cord (7) is wound on and which is connected with a coil spring (5), and a stopper mechanism working cooperatively with the rotary wheel (6) and including a functional rail, a ball (3) and a rolling assisting device. The functional rail comprises a locking rail, a communicating rail (25) and annular rails (21, 22) which are connected, groove-shaped and arranged around an outer circumference of the rotary wheel (6). A guide groove (91) is provided on the rolling assisting device, and two ends of the guide groove (91) are located at the upper and lower sides of the outer circumference of the rotary wheel (6) respectively. The guide groove (91) cooperates with the functional rail to hold the ball (3). When the rotary wheel (6) rotates, the ball (3) rolls in the functional rail to lock or unlock rotation of the rotary wheel (6).

The present disclosure provides a hose reel enclosure for a hose reel. The hose reel enclosure can include a unitary housing, a hose reel assembly, and a hose guide. The unitary housing can include lateral supports. The hose reel assembly can be disposed within the unitary housing and can be configured to receive the hose. The hose guide can be disposed within the unitary housing and configured to receive a free end of the hose.
