A cleaning device is configured to access and remove fluid from and dry a moat region defined by a hub of a medical connector, thereby minimizing the potential for bacterial growth in the hub. The cleaning device takes the form of an absorbent block which can be inserted into the moat by extending about a central male fitting and into a gap between the male fitting and the inner wall of a female hub of the medical connector. In a preferred embodiment of the invention, the block takes the form of a tubular cylinder particularly configured for use on ENFit medical connectors wherein the absorptive feature of the cleaning device can be employed alone or in combination with another cleaning tool used to first remove any existing dried and caked solution in the hub before removing residual cleaning fluid from the moat.

A pipe scraper (1) comprising: a housing (2) comprising a bore (21) having a centre axis and an open end (24) that allows access to the bore (21), the bore (21) being shaped to receive into its open end (24) at least a portion of each of two pipes (19, 20) of an assembly of two concentric pipes (19, 20), wherein the assembly of two concentric pipes (19, 20) comprises a pipe (19) having a smaller diameter, and a pipe (20) having a larger diameter, and the end of the pipe (20) having the larger diameter is separated from the end of the pipe (19) having the smaller diameter by a distance along the central axis of the assembly; a first scraper tool assembly 9, 10, 11, 16) secured to the housing (2), configured to urge a first scraper tool (9) radially inwards, and positioned at a first radial distance from the centre axis of the bore (21), and at a first axial distance from the open end (24) of the bore (21); a second scraper tool assembly (13, 14, 15, 17) secured to the housing (2), configured to urge a second scraper tool (13) radially inwards, and positioned at a second radial distance from the centre axis of the bore (21), and at a second axial distance from the open end (24) of the bore (21), wherein the first radial distance is smaller than the second radial distance, and the first axial distance is larger than the second axial distance; and a transmission means (4) to allow torque to be delivered to the housing (2) to cause rotation of the housing (2) about the centre axis of the bore (21); wherein the first scraper tool (9) is configured so that rotation of the housing (2) will cause the first scraper tool (9) to scrape portions of a pipe (20) that are in contact with the first scraper tool (9), and wherein the second scraper tool (13) is configured so that rotation of the housing (2) will cause the second scraper tool (13) to scrape portions of a pipe (19) that are in contact with the second scraper tool (13).

The present invention addresses to an adaptation of a laser system in a reactor for the application of laser radiation, promoting the thermal catalysis of the complexation reactions of barium sulfate (BaSO.sub.4), strontium sulfate (SrSO.sub.4) and CaCO.sub.3 with application in fields of drilling and completion of wells, as well as lifting and draining systems; in this case, aiming at the removal of scale at an appropriate temperature for the complexation and consequent dissolution of the scale salt in subsea equipment of the production systems.
